Description
Technical field
This utility model relates to bridge crane manufacturing technology field, especially a kind of pedal hydraulic brake for bridge crane.
Background technology
Iron-smelter winding-up workshop is as the auxiliary shop producing 10000000 tons of pig iron per year, and this workshop adopts bridge crane to carry out blast-furnace coal powder injection, owing to annual production is relatively big, causes that the workload of bridge crane is big, uses frequently.In actual production, whether the brake of bridge crane is sensitive, reliably, it it is one of important indicator restricting bridge crane safe operation, this bridge crane includes two braked wheels and acts on two electrohydraulic brakes of the two braked wheel respectively, in actual production, there is the problem that reliability is not high in electrohydraulic brake, concrete manifestation is as follows: when 1) abrasion of electrohydraulic brake working clearance increases, can not be adjusted accordingly in time, cause brake fade, poor reliability, ensure that brake normally uses, will frequently adjust brake, the working strength of maintenance mans and operative employee is big；2) during the tightness difference that electrohydraulic brake adjusts, the braking moment of both sides is not etc., during parking, one braked wheel stops operating, another is also rotating, two sets of transmission mechanism run asynchronous, the crossbeam causing braking rear axle type crane is crooked so that it is wheel gnawing rail, the substantial equipment accident that runway grider ftractures even occurs；3) when the tripping operation of prominent chance overhead traveling crane has a power failure, owing to brake force is not enough, when cannot be carried out again " reversely " brake operating, bridge crane, under the effect of inertia, continues to run with, and security incident easily occurs；4) in electrohydraulic brake, lever movable joint is stuck, there are the reasons such as greasy dirt on brake shoe undue wear, brake wheel surface, causes and can not check bridge crane, and namely after power-off, coasting distance is relatively big, easily causes security incident；5) slowly, not in time, bridge crane location is inaccurate in action for electrohydraulic brake braking, release reaction；6) hydraulic driver is in use, and leakage of oil often occurs, and causes pusher oil starvation, and braking effect is poor, it is impossible to meets and produces needs.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pedal hydraulic brake, the problem that it can solve existing electrohydraulic brake poor reliability.
In order to solve the problems referred to above, this utility model be the technical scheme is that this pedal hydraulic brake, including braked wheel and the brake acting on described braked wheel, described brake includes the support being located at described braked wheel both sides, being respectively arranged with an oil cylinder on each described support, the piston rod of described oil cylinder is provided with the friction plate corresponding with described braked wheel；Described oil cylinder is connected with main oil pipe each through allotter, and described main oil pipe is connected with oiling pump box by filling pump, and described oiling pump box is connected with scrunching button.
In technique scheme, technical scheme is it may also is that described filling pump is connected with supplementary fuel tank by oil inlet pipe more specifically.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that
1, the wear extent that causes of rubbing in braking procedure is followed up automatically by brake compensations, and after simultaneously ensureing to work each time return, the gap between friction plate and braked wheel is a steady state value, and this steady state value is 0.2mm-0.5mm；
2, this pedal hydraulic brake can improve the reliability of brake, there is braking sensitive, reliable, the advantage that noiselessness, brakeless are stuck, braked wheel both sides braking moment is equal, it is easily achieved quick startup, braking and commutation simultaneously, efficiently solves electrohydraulic brake Problems existing aborning；
3, the angle saving the energy, pedal hydraulic brake power consumption is little, and maximum power consumption is 1.08kW h, more originally the few power consumption more than 78% of electrohydraulic brake.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Embodiment as shown in Fig. 1 pedal hydraulic brake, including braked wheel 2 and the brake 1 acting on this braked wheel 2, this brake 1 includes base 1-1 and is located at the support 1-3 of these braked wheel 2 both sides, each support 1-3 is respectively arranged with an oil cylinder 1-4, the piston rod of this oil cylinder 1-4 is provided with the friction plate 1-5 corresponding with braked wheel 2, this oil cylinder 1-4 is connected with branch oil pipe 3, this branch's oil pipe 3 is connected with main oil pipe 5 by allotter 4, this main oil pipe 5 is connected with oiling pump box 7 by filling pump 6, this oiling pump box 7 is connected with scrunching button 8, this filling pump 6 is connected with supplementary fuel tank 10 by oil inlet pipe 9.
During work, ride and scrunch press button 8, the oil of oiling pump box 7 through filling pump 6 its front end formed pressure, the pressure oil cylinder 1-4 to the support both sides of brake is transmitted by main oil pipe 5, allotter 4 and branch's oil pipe 3, piston in oil cylinder 1-4 moves forward under the effect of the pressure, promote with friction plate 1-5 to two lateral movements of braked wheel 2, and produce frictional damping moment between braked wheel 2, braked wheel 2 is made to shut down, so that the motor 11 being connected with braked wheel 2 and reductor 12 shut down, reach the purpose of brake.When oiling pump box 7 oil mass is few, by supplementary fuel tank 10 and oil inlet pipe 9, it is carried out repairing.After release scrunches button 8, oil release pressure in brake inside main oil pump case 7, main oil pump 6 does not have oil pressure through main oil pipe 5 and branch's oil pipe 3, thus oil cylinder 1-4 is also without pressure, thus the piston in oil cylinder 1-4 does not have pressure to act on support 1-3, thus friction plate 1-5 returns, take-off the brake wheel 2.Its fretting wear is automatically followed up compensation by the wear extent that causes of rubbing in braking procedure by the autocompensation installation in brake 1, ensureing to work each time simultaneously return after gap between friction plate 1-5 and braked wheel 2 be a steady state value, this steady state value is 0.2mm-0.5mm, until the abrasive material of friction plate 1-5 effective thickness exhausts and again need to more renew friction plate, brake oil then returns filling pump 6 along branch's oil pipe 3 and main oil pipe 5.Braking procedure principle is identical with a front braking procedure next time.
