Abstract
The utility model belongs to a modified wind-resistant braking device for a gantry crane and a tower crane. The utility model is characterized in that a single-acting spring-returning hydraulic oil cylinder and a clamping brake are arranged at both sides of the walking wheel of the crane to clamp the walking wheel to ensure that the walking wheel does not move on the rail due to the gale. The device which has favorable wind resistant effect can reliably perform braking by that a switch is turned on and turned off.
Description
The utility model relates to the accessory equipment of engineering Transport Machinery, particularly a kind of brake equipment of the hoisting crane of operation on track.
Large and medium-sized gate-type, the tower crane of running job are the visual plants of handling goods and materials on track, are of wide application.But because of its framework height, the windward side is big, and a face is little, and rolling resistance is little, and is very responsive to wind, meets bigger wind, may be blown, and orbits, and influences normal operation, even the grave accident that leads to derailing, tumbles.
Existing hoisting crane wind resistance brake equipment, as track " skate ", electromagnetic brake, leading screw rail clamping device etc., defectiveness all, wind resistance braking reliably in the time of can not guaranteeing lifting opportunity wind.
The purpose of this utility model provides the wind resistance brake equipment of a kind of easy and simple to handle, braking failure-free gate-type, tower crane.
Task of the present utility model is finished like this: the folder lock that is promoted by hydraulic ram is installed in the some or all road wheels both sides at hoisting crane.When meeting wind, clamp road wheel, finally limit hoisting crane rolling in orbit, reach the purpose of wind resistance braking.
Embodiment further describes the utility model below in conjunction with accompanying drawing.
Fig. 1 is gate-type, tower crane wind resistance brake equipment scheme drawing.
Fig. 2 is wind resistance brake equipment hydraulic circuit figure.
As shown in Figure 1, go up mounting bracket (4), make the fixture block (5) of folder lock (3) place hoisting crane road wheel (6) both sides at gate-type, tower crane (1).Folder lock (3) is pushed by a pair of single-acting spring reset oil cylinder (2).Its principle of work as shown in Figure 2.
Hoisting crane is done the time spent driver and is closed a floodgate that (be Fig. 1 2) promotes piston and Jia Zha (3) after check valve (11), normal opened type electromagnetic valve (15) and sequence valve (16) input unidirectional spring drawback cylinder (13) through filtering from filter (8) with the hydraulic oil in the fuel tank (10) for starter motor (10), unidirectional fix-displacement pump (9), makes brake shoe (5) loose from the operation that can orbit of road wheel (6) (retracing spring is compressed in the oil cylinder (13) at this moment) hoisting crane.Pressure relay (12) and electromagnetic valve (15) and sequence valve (16) decomposition pressure control loop.
When hoisting crane stops operation or the prominent strong wind of meeting during operation, the outage as long as the driver operates a switch, the hydraulic circuit quick relief, retracing spring promotion piston and Jia Zha (3) in the oil cylinder (13) are pressed on the road wheel (6) brake shoe (5), press from both sides dead road wheel (6).Like this, no matter have wind calm, the wind strong wind is little, and hoisting crane can not gone up at track (7) and move.
Brake shoe (5) on the folder lock (3) can use general brake plate, also can use alloy from waste cutter head heap
Weldering forms, and braking effect is better like this.
Claims (3)
1, a kind of gate-type, tower crane wind resistance brake equipment is characterized in that said wind resistance brake equipment is made up of folder lock (3) that is installed in hoisting crane road wheel (6) both sides and the single-acting spring reset oil cylinder (2) and the hydraulic control system that promote folder lock (3).
2, hoisting crane wind resistance brake equipment according to claim 1 is characterized in that hydraulic control system is connected to form by motor (10), unidirectional fix-displacement pump (9), check valve (11), pressure relay (12), normal opened type electromagnetic valve (15) and sequence valve (16).
3, hoisting crane wind resistance brake equipment according to claim 1 and 2 is characterized in that the brake shoe (5) of said folder lock (3) is formed by the built-up welding of alloy from waste cutter head.
