Abstract
The utility model relates to a hydraulic band-type block brake, which is suitable for all the band-type brakes of various gantry cranes and hoisting machines. The hydraulic band-type block brake comprises an oil tank, a hydraulic cylinder, a main arm, springs, a pair of auxiliary arms, a pull rod, a bottom frame, a brake rubber frame and the brake rubber. The hydraulic band-type block brake is characterized in that a piston rod of the hydraulic cylinder is in pivotal connection with an operating lever; the other end of the operating lever is pivotally fixed to machine frames of the crane. The hydraulic principle of the hydraulic band-type brake adopted by the utility model is characterized in that no vibration is generated. The band-type brake of the utility model can brake with safety, smoothness and reliability when in power failure and power down times, or electric appliances have fault.
Description
The utility model relates to a kind of crane band-type brake block brake, particularly a kind of hydraulicdriven crane band-type brake block brake.
Existing crane drg comprises two kinds of electromagnetism block brake and power hydraulic pressure piece formula actuators.The electromagnetism block brake comprises calutron, spring and band-type brake piece.Under the crane normal operation, electromagnetic force unclamps the band-type brake piece, PTO Power Take Off when crane walks to desired location, and the calutron degaussing, the band-type brake piece is embraced axletree and is realized stopping under the effect of spring force.Electrohydraulic brake comprises the hydraulic braking sysgtem electrical controller of unifying.
These two kinds of brake equipments all be unable to do without.The user feels that electric control braking stops suddenly in actual moving process, and vibration is big, makes bolt looseness easily.And often, make by the handling article and aloft sway, sometimes even the generation major accident because the fault of power down or electrical equipment itself makes crane be not intended to brake suddenly.
The purpose of this utility model provides a kind of crane hydraulic contracting block brake device, it need not electrical controller, can make crane slip arbitrarily in its stroke range, slow shape and emergency braking, it can also reach the purpose of saves energy, makes the main motor of crane " cart " " dolly " save the electric energy of 40-50%.
Crane hydraulic contracting block brake of the present utility model comprises fuel tank, hydraulic actuating cylinder, main support arm, spring, a pair of secondary support arm, pull bar, underframe, brake rubber block frame and brake rubber block.The piston rod of hydraulic actuating cylinder connects a stretcher or hand lever, one bar oil circuit leads to fuel tank, another oil circuit connects a hydraulic pressure and divides cylinder, hydraulic pressure divides cylinder to be fixed on the main support arm, captive joint for one in its piston rod and the secondary support arm, one end of main support arm and an end of pull bar are fixed with adjustable clearance, the main support arm other end is provided with pin shaft hole, be connected with above-mentioned secondary support arm hinge with underframe by bearing pin, on another some a pull back spring is housed also on this pair support arm, the other end of spring is contained on the main support arm, and the other end of pull bar is connected with another secondary support arm hinge.Some difference pivotal joint one brake shoe block in the middle of on the two secondary support arms, the other end pivot of stretcher or hand lever is fixed on the crane frame.
Engaging accompanying drawing below is explained in detail the present invention.
Accompanying drawing is a schematic diagram of the present utility model.
As shown in the figure, the piston rod of hydraulic actuating cylinder 3 connects a stretcher or hand lever 1, one bar oil circuit leads to fuel tank 2, another oil circuit 4 connects a hydraulic pressure and divides cylinder 12, hydraulic pressure divides cylinder 12 to be fixed on the main support arm 10, captive joint for one in its piston rod and the secondary support arm 6, one end of main support arm and an end of pull bar 13 are fixed with adjustable clearance, main support arm 10 other ends are provided with pin shaft hole, be connected with above-mentioned secondary support arm hinge with underframe 7 by bearing pin, one pull back spring 6 also is housed on another aspect on this pair support arm, and the other end of spring is contained on the main support arm, and the other end of pull bar 13 is connected with another secondary support arm hinge.Some difference pivotal joint one brake shoe block 9 in the middle of on the two secondary support arms is equipped with brake rubber block 8 on the brake shoe block.
When stretcher or hand lever are applied certain force, hydraulic oil in the hydraulic actuating cylinder 3 enters hydraulic pressure by oil pipe 4 and divides cylinder 12, make hydraulic pressure divide cylinder 12 to produce a pressure, directly affact on main support arm 10 and the secondary support arm 6, main support arm and secondary support arm are given damper brake skin bit 9 and brake rubber block 8 with this transmission of pressure again, make brake rubber block 8 tightly embrace rotor, reach the purpose of brake.
After having eliminated the power on stretcher or the hand lever 1, pull back spring 6 draws the meeting original position with main support arm 10 and secondary support arm 6, and at this moment, brake rubber block 8 unclamps rotor, and crane can normally move.
Because crane drg of the present utility model adopts the hydraulic efficiency pressure system of manpower control, therefore use more steadily, be difficult for having an accident, safe and reliable.
Claims (3)
1. hydraulic contracting block brake that is used for crane, comprise fuel tank, hydraulic actuating cylinder, main support arm, spring, a pair of secondary support arm, pull bar, underframe, brake rubber block frame and brake rubber block, an oil circuit of hydraulic actuating cylinder leads to fuel tank, another oil circuit connects a hydraulic pressure and divides cylinder, hydraulic pressure divides cylinder to be fixed on the main support arm, captive joint for one in its piston rod and the secondary support arm, one end of main support arm and an end of pull bar are fixed with adjustable clearance, the main support arm other end is provided with pin shaft hole, be connected with above-mentioned secondary support arm hinge with underframe by bearing pin, on another some a pull back spring is housed also on this pair support arm, the other end of spring is contained on the main support arm, the other end of pull bar is connected with another secondary support arm hinge, some difference pivotal joint one brake shoe block in the middle of on the two secondary support arms, it is characterized in that: the piston rod of hydraulic actuating cylinder and a joystick pivotal joint, the other end pivot of joystick is fixed on the crane frame.
2. drg as claimed in claim 1, it is characterized in that: described joystick is a stretcher.
