Description
Technical field
The utility model relates to a kind of control devices, especially overhead traveling crane cart arrester control device.
Background technique
It is responsible for making for 22 overhead traveling cranes of full factory in the stainless wire rolling plants mechanical work area of Shanxi Taigang Stainless Steel Co., Ltd
With, maintenance, repair work, main target is to ensure that overhead traveling crane zero failure, zero complaint, provides high-efficiency high-quality service for production.And day
The brake of the cart of vehicle is to ensure that one of the important component that overhead traveling crane operates normally again, my stainless wire rolling plants lifting equipment is most of
For the old equipment of the sixties, the mode of braking of lifting equipment cart is braked with vehicle, i.e., when motor operation, brake is beaten
It opens, the operation of lifting equipment cart；When motor stop when, brake automatic braking, cart by brake braking moment come stop to
Designated position.The advantages of this mode of braking is that route is simple, convenient for safeguarding, cost is relatively low.But have the shortcomings that it is larger i.e.: 1.
Operator must repeatedly for accurate stopping or repeatedly crawl operates, and the probability that maloperation occurs increases, and increases security risk；
2. will cause hanging object amplitude of fluctuation if braking moment adjustment is improper greatly or hanging object rotate, object strike most probably occurs or rises
Grievous hurt accident；3. lifting equipment cargo motor long-time frequent starting, stopping will cause overload operation, often make in this way
At motor burning.
Summary of the invention
The technical problem to be solved by the utility model is to how to reduce the scaling loss of motor, avoid it is dangerous in work
Factor, it is ensured that equipment operates normally, and creates benefit for enterprise.
The technical scheme adopted by the utility model is overhead traveling crane cart brake dedicated control device, 380V AC power source
The three-phase alternating current input terminal of 20 contactor of CJ10-, the three-phase alternating current output end of 20 contactor of CJ10-are connected by connecting terminal
The brake of overhead traveling crane cart is connected, 380V AC power source is transformed into 12V safety power supply, 12V safety electricity after transformer transformation
The source-series switch of DZ5-20/330 is connected in the control terminal of 20 contactor of CJ10-.
As a kind of preferred embodiment: the number of connecting terminal is more than or equal to 2.
The beneficial effects of the utility model are: reducing the initiation culture situation of lifting equipment motor, effectively extend
The service life of motor.It ensures that operation, the stopped process of lifting equipment are steady, brakes relatively reliable.It steps on and steps on DZ5-20/
330 switch can carry out according to the needs of production to lifting equipment carry out active brake, thus ensure that operation reliability and
Accuracy effectively meets production safety, steady, efficient operation demand, that is, require steady operator, quasi-, fast, safety,
It is reasonable to require, effectively raise the serviceability rate, running rate and working efficiency of equipment.This cart brake not only reduces behaviour
Make the labor intensity and degree of fatigue of personnel, and simple, convenient, practical, make operator that can more more concentrate one's energy, protects
Hindered job specification, standard, efficiently, significantly reduce the security risk of operation process, for safe operation improve it is strong
It ensures.
Detailed description of the invention
Fig. 1 is the circuit diagram of the utility model；
Wherein, 1,380V AC power source, 2, connecting terminal, 3, transformer, 4,20 contactor of CJ10-, 5, overhead traveling crane cart
Brake, 6, the switch of DZ5-20/330.
Specific embodiment
As shown in Figure 1, the utility model is the improvement to existing overhead traveling crane cart arrester control device, existing overhead traveling crane
Cart arrester control device by 380V AC power source be directly connected to overhead traveling crane cart brake and overhead traveling crane cart it is electronic
Machine, when connecting 380V AC power source, the brake of overhead traveling crane cart decontrols the motor brake to overhead traveling crane cart, overhead traveling crane cart
Motor start turning, when closing 380V AC power source, braking of the brake of overhead traveling crane cart to overhead traveling crane cart makes electricity
Motivation quickly stops, and operator repeatedly or repeatedly crawl operation (must connect 380V alternating current for accurate stopping when parking
Source), and once connect 380V AC power source motor and start to rotate, it results in the probability that maloperation occurs to increase in this way, increases
Security risk.
The utility model is installed a DZ5-20/330 on the basis of existing overhead traveling crane cart arrester control device and is switched
With 20 contactor of CJ10-, and with realizing control to 20 contactor of CJ10-, while overhead traveling crane after 380V AC power source transformation
The motor of cart can be closed repeatedly in this way when needing to brake from this improved controller using different two-way power supplys
Conjunction/disconnection DZ5-20/330 is switched, to realize the safety arrestment to overhead traveling crane cart.
Since overhead traveling crane cart arrester control device uses 380V power supply, and it is to be shorted that braking process, which is equal to,
Short-time current intensity is very big, it is easy to electric wire is burnt, therefore the cable space for connecting 380V power supply is connected by connecting terminal, one
Denier, which is burnt, is easily exchanged new electric wire.
