Abstract

The utility model relates to an automatic braking locator which can be used in water and used for wind proof for a crane. The utility model comprises a pair of base plates which are provided with a compression cylinder, a pull rod, a spring plate, etc.; one metal shoe is connected with the pull rod and the spring plate, and the tip of the metal shoe is provided with a convex hull which can make the wheels of the crane reliably fixed on a concave part which is behind the convex hull and fully separated from track; the reciprocating motion of a piston which is arranged in the compression cylinder pulls the pull rod and drives the metal shoe to make the metal shoe lifted or released to execute the braking task. The braking device of the utility model has no electric element, so the utility model fears no tidewater immersion and can perform the task of automatic braking and locating of the crane wheels in water.

Description

Automatic braking locator

Be used for the self-actuating brake steady arm on the hoisting crane.The utility model belongs to a kind of windproof retouching and decides device.

The hoisting crane of open work, windproof retouching is to be related to the significant problem that crane safety uses surely.Especially large bridge crane formula high pedestal jib crane because there is not dead-man's device, is blown away often meeting high wind by chance, causes a serious accident and property damage.The windproof fixed point pile anchoring chaining method that set down measures of retouching that adopts before, way toward big wheel plate hole dowel rod, place skate or adopt the method etc. of rail clamping device, but these methods all are difficult to solve meet high wind or the self-actuating brake problem in wind and rain tidewater by chance when operation.

Task of the present utility model is, for fear of the generation of above-mentioned accident and improve traditional windproof retouching and decide mode, particularly solves the brake orientation problem of lifting wheel in water the time.Improve the reliability and the practicality of brake location, and a kind of hoisting crane of design-calculated self-actuating brake steady arm.

Basic design of the present utility model is, the self-actuating brake steady arm has a sole plate, a pull bar is arranged above him, the pull bar upper end connects with sole plate, the lower end connects with the skate afterbody, a spring plate is arranged, its the upper end with bolt to sole plate, the lower end connects with the middle part of skate, have a regulating plate to be contained in the back of spring plate, can cooperate the gap of adjusting between skate and track and the wheel with spring plate, the front end of skate has a convex closure, correspondingly there are two holes the rear end, axle cooperation on pull bar and spring plate is connected to respectively, and a cylinder is arranged, and the rear end is connected on the sole plate with axle, front end is linked to pull bar with axle, complete self-actuating brake steady arm can be sat by the connection hook and the coupling spindle that are welded on the hoisting crane travelling wheel cover plate, is installed on the hoisting crane, an air compressor and an electromagnetic conversion air valve are arranged, be installed on the hoisting crane.

Self-actuating brake steady arm by above-mentioned design concept manufacturing, start air compressor and electromagnetic valve in use, pressurized air is promptly passed through electromagnetic valve and pipeline, be cylinder charge, make pressurized air promote piston, the pulling pull bar, pull bar promptly can cooperate with spring plate pulls out skate and mentions, and hoisting crane gets final product normal operation, during brake, turn-off electromagnetic valve, discharge the pressurized air in the cylinder, pull bar is just under the effect of deadweight and spring plate, skate is put on the track, fast the lifting wheel of operation fell in the recess after can pressing the convex closure of skate front end, at the bottom of the skate with the effect of interorbital friction drag under, force hoisting crane out of service to reach the purpose of brake.By the break-make of automatic guidance electric switch control electromagnetic valve, can finish the self-actuating brake location tasks.

Be a most preferred embodiment of this practicality row type below: as shown in the figure, be welded with hook (4) and coupling spindle on the cover plate on the lifting wheel and sit (8), sole plate (7) is made by two metal sheets, have pull bar (14) above it, pull bar (14) upper end is porose and be enclosed within on the pull rod shaft (5), the lower end has slotted hole, axle (17) is inserted in the hole of pull bar (14) lower end slotted hole and skate (16) rear end, has a spring plate (2) and regulating plate (3) to be fixed on the sole plate (7) by bolt (1).Regulating plate (3) is contained in the back of spring plate (2), can cooperate with spring plate and adjust crack between skate and the track, there is its toe cap of a skate (16) that one convex closure is arranged, one recess is arranged behind the convex closure, the rear end correspondingly has two holes, by being inserted in axle (15) and the axle (17) in two holes respectively, skate (16) is connected on pull bar (14) and the spring plate (2), there is a cylinder (11) to be connected on the sole plate (7), tracheae (10), piston (13) is housed on the cylinder (11) is connected on the pull bar (14) by spool (6) by axle (12).Also have an air compressor and electromagnetic air change-over valve, be installed on the hoisting crane, tracheae (10) on the gas thick stick (11) connects with the freeing pipe of electromagnetic air change-over valve and air compressor, when starting air compressor and electromagnetic air change-over valve, pressurized air can enter in the cylinder (11) by electromagnetic air change-over valve and tracheae (10), pressurized air can promote piston (13) pulling pull bar (14), pull bar is promptly by axle (17) pulling skate (16), skate can be mentioned by spring plate (2), hoisting crane gets final product normal operation, during brake, close solenoid directional control valve, discharge the pressurized air in the cylinder (11), piston (13) is when losing air pressure, the screen resilience that utilizes spring plate (2) and pull bar (14) cooperate and are put on the track (18) skate (16) is parallel, carry out the location tasks of braking.Complete self-actuating brake steady arm can be sat on (8) by the connection that hook (4) and axle (9) are installed on the hoisting crane.

Claims

1, be used for the self-actuating brake steady arm on the hoisting crane, belong to a kind of windproof retouching and decide device, it comprises sole plate (7), a pull bar (14), a cylinder (11), a spring plate (2), a skate (16), it is characterized in that said sole plate (7), front end is equipped with spring plate (2) and pull bar (14) and gas thick stick (11) and piston (13), spring plate (2) and pull bar (14) are connected in respectively on the skate (16), when filling with pressurized air for cylinder (11), can promote piston (14) pulling pull bar (14), cooperate by pull bar (14) and spring plate (2) to drive skate (16) together and mention, promote piston by the cylinder compressed air, the pulling pull bar, the rise and the let-down of pull bar control skate can be finished the self-actuating brake location tasks.
