Abstract
The utility model discloses an electrohydraulic pushed calipers disk brake. The electrohydraulic pushed caliper disk brake comprises an electricdevice pushing device, a brake spring and a large triangular plate, wherein the large triangular plate is connected with a brake calipers and an adjusting screw rod, and the adjusting screw rod is connected with the brake calipers. Brake blocks are arranged on the brake calipers, gap is arranged between two brake blocks, a hoisting device brake disk can extend in the brake blocks, and the middle end of the brake calipers is fixed on a brake frame. The utility model has the advantages that the patent does not need additionally providing with a high pressure oil and a high pressure air systems, and the leakage problem and the maintenance difficulty of the high pressure oil and the high pressure air can be relieved because the utility model and the hoisting device use electricity together. Therefore, the cost can be reduced by one half at least, besides, the utility model has the advantages of compact structure, small volume, light weight and convenient installation and use. The utility model only needs being arranged near the brake disk, a brake rubber is convenient for replacing after the brake rubber of a brake is worn, and the replacement can be performed only by fixing a bolt after the brake rubber is loosened.
Description
Technical field
The utility model relates to a kind of electric liquid and promotes clipper disk brake, and especially a kind of electric liquid promotes clipper disk brake.
Background technology
The disc-brake that high-power in the past weight-lifting equipment uses is to enrich existing drg by high pressure or high pressure gas to produce big braking force, thereby a cover system and equipment need be set in addition, and the result causes cost too high, and high pressure oil, high pressure gas leakproof problem are difficult to handle simultaneously, et out of order, maintenance is difficulty also.
Summary of the invention
The purpose of this utility model is to provide a kind of electric liquid to promote clipper disk brake, use this electricity liquid to promote clipper disk brake, needn't establish high pressure oil, high pressure air system in addition, with the same electrification of weight-lifting equipment, also exempt the difficulty of high pressure oil, high pressure gas leakage problem and maintenance, thereby make cost can deduct half at least.
The technical solution of the utility model is: a kind of electric liquid promotes clipper disk brake, this electricity liquid promotes clipper disk brake and comprises electric liquid pusher, retarding spring, support, pusher, retarding spring, support upper end and connecting rod, link to each other by bearing pin, pusher, retarding spring, the support lower end links to each other with frame, the pull bar upper end links to each other with bearing pin with connecting rod, the pull bar lower end links to each other with vertically arranged little set square with bearing pin, little set square is fixed on the support with bearing pin, the little set square other end links to each other with bearing pin with Hooke's coupling, the big set square that the Hooke's coupling other end is installed with bearing pin and level links to each other, big set square end in addition links to each other with adjusting screw(rod) with a slice pawl of brake clamp, the adjusting screw(rod) other end links to each other with another pawl of bearing pin and brake clamp, slipper is installed on the brake clamp with bearing pin, in the middle of two slipper certain interval is arranged, the weight-lifting equipment brake disc can be stretched in the slipper, the brake clamp middle-end is fixed on the frame with bearing pin.
Advantage of the present utility model is: this patent needn't be established high pressure oil, high pressure air system in addition, with the same electrification of weight-lifting equipment, also exempts the difficulty of high pressure oil, high pressure gas leakage problem and maintenance, thereby makes cost can deduct half at least.This patent compact conformation, volume are little, in light weight, easy to install and use, only need be directly installed on by the brake disc, and after the brake shelling decreased, it was also convenient and swift to change brake rubber block, only need unclamp behind the brake shoe bolt of rear end plate and change and get final product.Lock torque is big, applicable high-power weight-lifting equipment, and the winch as use in the mine for safety, requires to have at least the lock torque more than three times, 1.6 meters winch lock torques reach 96000 Ns more than the rice, and this patent satisfies three times of lock torque requirements fully.Previously used electric liquid promotes block brake and the electromagnetism block brake all can not satisfy this requirement.
Description of drawings
Fig. 1 is that the utility model electricity liquid promotes the clipper disk brake structural representation.
The specific embodiment
A kind of electric liquid promotes clipper disk brake, this electricity liquid promotes clipper disk brake and comprises electric liquid pusher 1, retarding spring 2, support 5, pusher 1, retarding spring 2, support 5 upper ends and connecting rod 3, link to each other by bearing pin, pusher 1, retarding spring 2, support 5 lower ends link to each other with frame 12, pull bar 4 upper ends link to each other with connecting rod 3 usefulness bearing pins, pull bar 4 lower ends link to each other with vertically arranged little set square 6 with bearing pin, little set square 6 usefulness bearing pins are fixed on the support 5, little set square 6 other ends link to each other with Hooke's coupling 7 usefulness bearing pins, the big set square 8 that Hooke's coupling 7 other ends are installed with bearing pin and level links to each other, big set square 8 end in addition links to each other with adjusting screw(rod) 9 with a slice pawl of brake clamp 11, adjusting screw(rod) 9 other ends link to each other with brake clamp 11 another pawls with bearing pin, slipper 10 usefulness bearing pins are installed on the brake clamp 11, in the middle of two slipper 10 certain interval is arranged, weight-lifting equipment brake disc 13 can be stretched in the slipper, brake clamp 11 middle-ends are fixed on the frame 12 with bearing pin.
Principle of work: when weight-lifting equipment is worked, must send earlier, electric liquid pusher also must be established beginning work by cable simultaneously, the pusher push rod rises, promoting connecting rod also rises, because of the connecting rod other end links to each other with support, can only rotate and can not rise, thereby connecting rod drives spring bar and pull bar rises, retarding spring is compressed, the savings spring force, pull bar is little set square pulling rotation, makes the brake clamp tail end dwindle the gap the big set square of horizontal positioned by Hooke's coupling, and slipper then increases the gap, slipper and brake disc disengage and declutch, and weight-lifting equipment just can be started working.When weight-lifting equipment has an accident or have a power failure, the staff in time presses power-off switch, electricity liquid pusher does not have electricity and loses thrust, and this moment, retarding spring release spring power was drop-down with pipe link and pull bar, pull bar promotes little set square contrarotation, and promote big set square contrarotation by Hooke's coupling, thereby two pawl tail ends of brake clamp are open, slipper then clamps brake disc, produce braking force, make drg realize safety arrestment.
