Abstract

The utility model provides a stereo garage traction control device capable of automatically controlling counter weight. The stereo garage traction control device capable of automatically controlling the counter weight comprises a control system, a traction system and a dynamic counter weight system. The dynamic counter weight system comprises a set of fixed counter weight boxes, a plurality of sets of variable counter weight boxes, a rope holder and spring rope winders. The weight of the fixed counter weight boxes is the same as that of a lift car, and the fixed counter weight boxes are connected with the lift car through a steel wire which winds around rope wheels of a traction motor. The variable counter weight boxes can be combined into variable counter weight box combinations with various types of weight. A plurality of spring rope winders are arranged on the top of a garage. The variable counter weight boxes are respectively hung on the spring rope winders. The rope holder is used for controlling the length of the steel wire. The variable counter weight boxes initially are suspended on the top layer of the garage. In the operating process, electromagnetic chucks which control the corresponding positions of the fixed counter weight boxes through a program absorb the variable counter weight boxes to change the counter weight matched with the load, and consequently operating energy consumption and operating cost of a stereo garage system can be reduced.

Description

Automatically control the multi-storied garage traction control device of counterweight weight

Technical field

The utility model relates to a kind of traction control device that is applied to the vertical-lifting multi-storied garage, it is characterized in that controlling the gross weight of counterweight weight and car and load in the multi-storied garage lifting process near balance, belongs to the crane gear technical field.

Background technology

At present, known vertical-lifting multi-storied garage traction system is that wire rope is fixed on the car by traction sheave grooving one end, and the other end is fixed on the counterweight, and wire rope and traction sheave produce frictional force and drive car movement.The traction system counterweight is essential, and function is balance car and fractional load weight, reduces the motor power (output) loss.Counterweight weight is fixed, and the weight design is W=P+KQ with the equation expression, and in the formula, W is counterweight weight (kg); P is car deadweight (kg); K is coefficient of balance, gets 0.4-0.5; Q is rated weight (kg).Coefficient of balance K clearly stipulates should be 40%-50% by standard GB 10060-93 4.6.1 (a) bar.The multi-storied garage load weight is a definite value range, and therefore traditional hoisting motor power must satisfy 60% and system friction of load weight, and it is big to design bigger motor power (output) value and operation energy consumption.If can realize real-time counterweight weight balancing control, just can adopt high speed small-power hoisting motor in design, can not only reduce system's operation energy consumption, also can promote conventional stereo garage traction speed ability.

Summary of the invention

In order to overcome the fixed mode deficiency of traditional counterweight weight, the utility model provides a kind of traction control device, the gross weight of counterweight weight and car and load is near balance in the control multi-storied garage lifting process, namely be to make coefficient of balance K near 100%, because the hoisting motor load is very little during operation, will reduce stereo garage system operation energy consumption and operating cost; The scope of design of traction system rated load, the speed of service can expand and is twice abovely, to reduce the multi-storied garage cost and promotes the advantage of garage performance.

The technical scheme that its technical problem that solves the utility model adopts mark by reference to the accompanying drawings is described in detail as follows: the traction control device is made up of control system, traction system and dynamic counterweight system.Control system comprises programmable logic controller 11 and LOAD CELLS 18; Traction system comprises high speed small-power hoisting motor 9, traction sheave 10, wire rope 16 and car 17, dynamically counterweight system comprise a cover fixing to loaded van 3, magnechuck 4, overlap more variable to loaded van 6, rope brake and electromagnet 7 and spring ropewinder 8.Wherein, described fixing identical with car 17 weight to loaded van 3, walk around the hoisting motor rope sheave by wire rope 16 and connect, make unloaded up-downgoing process keep counterbalancing, reduce no-load running consumption; A plurality of spring ropewinder 8(prior aries are equipped with at top, described garage), each spring ropewinder 8 plays variable to loaded van 6 respectively, off working state rope brake and electromagnet 7(prior art) band-type brake, control variablely to the loaded van position of hovering, variable loaded van 6 is initially hovered over the garage top layer; Described many covers are variable to be made as multiple weight capable of being combined to loaded van 6, all should be more than or equal to the multi-storied garage peak load to the loaded van gross weight, when stopping vehicle being arranged on the car 17, automatically select to cooperate counterweight by programmable logic controller 11 programs, connection is fixing variable to loaded van 6 to magnechuck 4 adhesives of loaded van 3 correspondence positions, thereby changes the counterweight weight that cooperates load; This device utilizes car and counterweight to be equal in weight at work, and the physical principle that gravitional force can be changed has mutually reduced traction system and dragged the merit that load consumes, thereby reached remarkable energy saving effect.

The obtained technological progress of the utility model is by simple form of structure, realize keeping in the traction system course of work the in a basic balance of counterweight and load with programmable controller program control, by such method of operation, multi-storied garage moves used power can reduce 60%-80%, realizes energy-conservation economize on electricity.Because the hoisting motor load of when operation is very little, the scope of design of traction system rated load, the speed of service can expand be twice above, the advantage that obtains to reduce the multi-storied garage cost and promote garage performance.
