Abstract

The utility model relates to a brake for the hoist of a crane. Because the prior brake system is in long-term switch-on regime and the hydraulic systems of two winding drums are working separately when a bridge crane is working for a long time, the whole set of the bridge crane is going to stop and the restarting time is long if any system works out. The utility model can solve the problem above. The utility model includes the technical measures as follow: the novel brake of the hoist of the bridge crane mainly consists of two sets of oil pressure devices; and each set of oil pressure device essentially consists of an oil cylinder 1, oil pipes 2, an electromagnetic directional valve 3, unloading relief valve 4 and an oil pump 5. A connection pipe 6 is connected between two oil pipes 2 which are used to connect two sets of oil pressure devices and the oil cylinder 1. An electromagnetic directional valve 7 is connected with the connection pipe 6, and an electromagnetic directional valve is connected with each oil pipe 2 which is connected with the oil cylinder 1. The brake greatly shortens the downtime and reduces the labor intensity of workers.

Description

The New Brake of crane in bridge type winch
Technical field
The utility model relates to winch, specifically belongs to the drg of crane in bridge type winch.
Background technology
The drg of on the crane in bridge type hoisting mechanism, installing, its effect be when hoisting mechanism owing to the causing under the emergency situation that object falls of component failures such as drg, reductor or coupler, utilize drg to act directly on the moment on the reel and the covering device that stops object to continue to fall.For on the hoisting mechanism that has two reels, two reels are equipped with a sure brake respectively.Its problem is because this system is in long-time "on" position when crane in bridge type works long hours; the hydraulic efficiency pressure system of two reels works alone respectively again; wherein any cover system et out of order; the capital directly causes the shutdown of whole crane in bridge type; influence is normal produces continuously, and its recovery time is long.
The utility model content
The utility model is to overcome above-mentioned deficiency, provides a kind of when reel of a cover system et out of order locking wherein, drives two cover sure brake work by an other cover system, also is to realize the New Brake of automatically controlled crane in bridge type winch.
Technical measures:
The New Brake of crane in bridge type winch, mainly by two the cover oil pressure installations forms, every cover oil pressure installation mainly by oil cylinder, and oil cylinder bonded assembly oil pipe, solenoid directional control valve, unloading overflow valve, oil pump form.In order to realize when reel of a cover system et out of order locking wherein, drive two cover sure brake work by an other cover system, and the purpose of realization automatically controlled, it is: two the cover oil pressure installations and oil cylinder bonded assembly oil pipe between connect pipe, on communicating pipe, connect solenoid directional control valve, every cover with oil cylinder bonded assembly oil pipe on be connected solenoid directional control valve.
It is: on the oil pipe above the solenoid directional control valve of every cover oil pressure detection table is installed.
The utility model compared with prior art, the floor time that sure brake causes significantly reduces, and has improved work efficiency, and can reduce staff's labour intensity.
Description of drawings
Fig. 1 is the New Brake structural representation of crane in bridge type winch
Fig. 2 is the circuit diagram of Fig. 1
Among the figure: 1-oil cylinder, 2-oil pipe, 3-solenoid directional control valve (original), 4-unloading overflow valve, 5-oil pump, 6-communicating pipe, 7-solenoid directional control valve (on communicating pipe), 8-solenoid directional control valve (on the oil pipe), 9-oil pressure detect table, P-pressure sensor, K-intermediate relay, Y-solenoid directional control valve, T-time relay, KM-oil pump power contactor, S-fault-indicating lamp
The specific embodiment
Be described in detail below in conjunction with accompanying drawing:
The New Brake of crane in bridge type winch by two the cover oil pressure installations forms, every cover oil pressure installation mainly by oil cylinder 1, and oil cylinder 1 bonded assembly oil pipe 2, solenoid directional control valve 3, unloading overflow valve 4, oil pump 5 form.Its two cover oil pressure installations and oil cylinder 1 bonded assembly oil pipe 2 between welding communicating pipe 6, the conventional solenoid directional control valve 7 of installing on communicating pipe 6; Every cover with oil cylinder 1 bonded assembly oil pipe 2 on the conventional solenoid directional control valve 8 of installing, in order to make solenoid directional control valve 8 normal operation, oil pressure is installed on the oil pipe above each solenoid directional control valve 82 is detected table 9.
Principle of work
When two cover system normal operation, work alone separately, do not disturb mutually.But when a cover system et out of order wherein can not be worked and when causing its sure brake locking reel, opens solenoid valve 7, conducting communicating pipe 6 is with hydraulic oil output oil pipe 2 sealings of fault hydraulic efficiency pressure system.That cover oil pump 5 by et out of order not drove and opened two reels operations this moment.Solenoid directional control valve 8 in electromagnetic valve 1 and the failure-free oil pressure installation switches, and makes hydraulic oil pass through communicating pipe 6 pairs two covers oil cylinder while fuel feeding, thereby opens the sure brake band-type brake.Its unlatching is very convenient, owing to adopt the control of electromagnetic valve change-over valve, just can finish the switching of two states several seconds, and hoisting crane is devoted oneself to work again by stopped status, and can not influence the safety effect of this sure brake.
