Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

0.1 General

According to GB/T 15706, this standard is a Class C standard.

The scope of this standard indicates the extent to which the machinery to which this standard applies and the hazards, hazards and hazardous events covered.

When the requirements of this Class C standard are different from those in the Class A or Class B standards, it is designed and manufactured in accordance with this Class C standard.

For machines, the requirements in this Class C standard take precedence over those in other standards.

This standard specifies the safety regulations for inclined elevators for the purpose of protecting personnel and goods, and prevents the normal use and maintenance of inclined elevators. Risk of accidents related to protection, inspection or emergency operations.

0.2 Factors to consider

Various types of inclined elevators have been considered due to the structural (civil engineering), inclination angle and external factors of the following structures. Risks and dangers such as.

a) large outward opening;

b) the possibility of walking in the hoistway;

c) the arrangement of the doors;

d) The horizontal component of the deceleration when the carrier is stopped.

It is possible to walk in the hoistway and the car top can be used as a maintenance work area. The relevant method for protecting workers and evacuating from the car is different.

0.3 principle

The following principles were adopted in the development of this standard.

This standard does not repeat the general techniques applicable to any electrical, mechanical and building structures including fire protection of building components. specification.

However, it is necessary to develop certain requirements to ensure good manufacturing quality, as they may be unique to manufacturers of inclined elevators.

The requirements, or because in the use of inclined elevators, may have more stringent requirements than other locations.

This standard gives the most basic requirements for buildings or structures installed in inclined elevators, and the relevant national regulations and other regulations are not Can be ignored.

Typical terms affected by this are the minimum requirements for the height of the machine room, the height between the pulleys and the size of the entrance.

When parts cannot be moved by hand due to weight, size and/or shape, then these parts should.

a) setting attachments for lifting by the lifting device; or

b) designed to be connected to a lifting attachment (eg by means of a threaded hole); or

c) has a shape that is easily connected to a standard type of lifting device.

This standard only specifies that the materials and components used should meet the requirements for safe operation of inclined elevators.

0.4 hypothesis

The content of this standard is based on the assumption that personnel can independently use inclined elevators.

The buyer and the supplier (installer) negotiated and agreed on the following (see Appendix O).

a) the intended use of the inclined elevator;

b) environmental conditions;

c) civil engineering issues;

d) other matters related to the installation location (eg high voltage power lines, bridges, dangerous buildings and natural barriers);

e) Matters related to rescue.

The risks associated with each component that makes up a complete inclined elevator have been considered and the corresponding requirements have been established. Parts.

--- Designed in accordance with common engineering practices and calculation specifications, taking into account all failure modes;

--- Have reliable mechanical and electrical structure;

--- Made of materials of sufficient strength and good quality;

---flawless. Do not use hazardous materials such as asbestos.

The parts are well maintained and in a normal working condition, and despite the wear and tear, they still meet the required dimensions.

The selected and configured components do not affect the safe operation of the inclined elevator under the expected environmental impact and specific working conditions.

Especially for the extreme temperatures approved by customers and suppliers, the choice of materials and components should pay special attention to maintaining their characteristics, such as the impact of steel.

Strength, hardness and performance of plastics, function of electrical components, viscosity of oil, etc.

The load-bearing support is designed to guarantee a load range of 0 to 100% of the rated load plus the design-allowed overload (see 5.11.2.5.2).

The safe and normal operation of the elevator inside the inclined line.

The requirements of this standard for electrical safety devices (see 5.11.1.2) are that if the electrical safety device fully complies with the requirements of this standard, then it is lost. The possibility of effectiveness does not have to be considered.

When the user uses the inclined elevator according to the predetermined method, the danger caused by his own negligence and unintentional carelessness shall be given. protection.

In some cases, the user may make some kind of reckless action, and this standard does not consider the possibility of two kinds of reckless actions at the same time. (or) Violation of the instructions for use.

If during the maintenance period, the safety device that the user usually does not easily access is intentionally put into an invalid state, the safe operation of the inclined elevator at this time If there is no guarantee, additional measures must be taken to ensure the safety of the user in accordance with the maintenance procedures.

It is assumed that maintenance personnel are instructed and work according to the regulations.

Horizontal forces and/or energy are given in the relevant provisions of this standard.

--- Usually the static force that a person can apply is. 300N;

--- The energy generated by the impact depends on the inclined elevator components that may have an impact. If there are no other regulations, the impact is generated The force is. 1000N.

In addition to the following, mechanical devices manufactured according to good examples and standards will not be damaged until they cannot be inspected. On the verge of danger. Consider the following mechanical failures.

---The breaking of the suspension device;

--- Runaway slip on the traction rope on the traction sheave;

--- Breaking and slackening of all connections of the auxiliary rope, chain and belt;

---Invalidation of one of the mechanical parts of the electromechanical brake involved in braking the brake wheel (or disc);

---Parts related to the main drive unit and the traction sheave failed;

---The wire rope leaves the pulley and leaves the roller with a change in the inclination angle;

---The resistance of the rope running;

--- Jamming or derailment of the carrier.

The carrier is free to fall from the lowest landing, allowing the safety gear to be inoperative before hitting the bumper.

When the speed of the carrier is still related to the main power frequency at the moment of mechanical braking, the speed at this time is assumed to be no more than 115% rated. Speed or corresponding grading speed. Facilities for hoisting heavier equipment are provided.

In order to ensure the normal operation of the equipment in the machine space (for example. considering the heat emitted by the equipment), the ambient temperature in the equipment room remains Between 5 ° C ~ 40 ° C. The access to the work area is adequately illuminated.

According to the maintenance instructions, the opening of the door or trap door of any protective device in the inclined elevator and/or outside the working area of the shaft does not hinder the building. The minimum channel required by regulations (see 0.3).

If more than one person is working on an inclined elevator at the same time, it is necessary to ensure proper communication between them.

During maintenance or inspection, if the guard has to be disassembled, the retaining member can remain in the protective suit when the guard is removed Set or on the device.
