Description
Technical field
The utility model belongs to coal mine fully-mechanized mining instrument field, particularly relates to a kind of endless rope winch auxiliary clamping device.
Background technology
At present, endless rope winch has become a kind of important transportation means of Chengjiao Coal Mine fully-mechanized mining working assistant conveyance, but in the transportation of reality, still there is a lot of indeterminable problem and drawback, particularly in the tunnel of big rise and fall, vehicle is easily caused to slide down, extruded cords rope causes distortion even to be ruptured, and brings potential safety hazard to transporting safely.The steel rope of endless rope winch is fixed on shuttle car two ends, and steel rope, by the tension wheel at tensioning hydro-cylinder place, walks around head roll, is connected with transport vehicle by shuttle car, and traction transport bunching carries out electrodeless transport.In vehicle operation, no matter shuttle car is still transporting in the middle of bunching at the two ends of transport bunching, vehicle is when tunnel larger by slope change, there is larger change along with the change of the gradient in the stressed meeting of shuttle car, along with the change that shuttle car is stressed, steel rope stressed also along with changing, shuttle car is to go up a hill or to going down the hill to run, shuttle car front and back end steel rope there will be one end tensioning and the other end relaxes.
After one end of steel rope is lax, because rope capacity is long, slack can through just passing to the position of head roll after a while, after the tensile force of head roll two ends steel rope changes, steel rope can be caused to skid above head roll, steel wire rope looseness amount is delivered to tensioning hydro-cylinder place, rear, tensioning hydro-cylinder again reaches equilibrium of pressure under the effect of energy storage, the action that can stretch or contract, thus steel wire rope looseness amount is absorbed, but this process need regular hour completes, so just easily cause potential safety hazard.
Utility model content
the purpose of this utility model is to provide a kind of endless rope winch auxiliary clamping device, device is for this problem, endless rope winch is installed a set of auxiliary clamping device, after steel rope generation is lax, require no head roll, directly carry out tensioning, efficiently solve this drawback of endless rope winch.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Endless rope winch auxiliary clamping device, comprise energy storage and the steel rope of tightening device, described pinch device also comprises housing, inner walls is installed with the first fixed pulley and the second fixed pulley, also movable pulley is provided with in housing, movable pulley is fixedly connected with the piston rod of auxiliary compressed oil cylinder, and steel rope walks around the first fixed pulley, movable pulley and the second fixed pulley successively, and auxiliary compressed oil cylinder is connected with the energy storage of tightening device.
Preferably, described movable pulley is fixedly connected with the piston rod of compressed oil cylinder by pin.
Preferably, the first described fixed pulley and the second fixed pulley are positioned at same level height.
Preferably, movable pulley is positioned at above the first fixed pulley and the second fixed pulley.
Preferably, described steel rope is walked around bottom the first fixed pulley successively, bottom movable pulley top and the second fixed pulley.
The utility model is arranged on head roll front, and the tensioning hydro-cylinder energy storage at auxiliary compressed oil cylinder and endless rope winch head roll rear is cascaded.After steel rope generation is lax, slack can reach rapidly head roll front, the steel wire tensioning power at movable pulley place reduces, auxiliary compressed oil cylinder can carry out contraction piston rod under the effect of energy storage, the related movable pulley of piston rod moves, and movable pulley produces displacement relative to the first fixing fixed pulley and the second fixed pulley, above carries steel rope, thus absorb rapidly the slack of steel rope, ensure the safe handling of endless rope winch.
The energy storage of auxiliary compressed oil cylinder and tightening device is cascaded, carry out work under auxiliary compressed oil cylinder is in same pressure condition with the tensioning hydro-cylinder of tightening device under the effect of energy storage, after auxiliary compressed oil cylinder action, finally meeting and the whole clamping system of endless rope winch reach the state of balance.
The utility model compared with prior art, tool has the following advantages: after steel wire tensioning power changes, without the need to can auto-tensioning be completed through head roll, the required time is short, speed is fast, avoid steel rope to skid on head roll, ensure that the friction force of head roll, ensure that the Transport Safety of endless rope winch.
Accompanying drawing explanation
fig. 1 is the structural representation of endless rope winch auxiliary clamping device in detailed description of the invention.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, endless rope winch auxiliary clamping device, comprise energy storage and the steel rope 7 of tightening device, also comprise housing 1, housing 1 inwall is installed with the first fixed pulley 5 and the second fixed pulley 6 being positioned at same level height, be positioned in housing 1 above first fixed pulley 5 and the second fixed pulley 6 and be also provided with movable pulley 4, movable pulley 4 is fixedly connected with by pin 3 with the piston rod of auxiliary compressed oil cylinder 2, steel rope 7 is walked around bottom the first fixed pulley 5 successively, bottom movable pulley 4 top and the second fixed pulley 6, auxiliary compressed oil cylinder 2 is connected with the energy storage of tightening device.
The utility model is arranged on head roll front, and auxiliary compressed oil cylinder 2 is cascaded with the tensioning hydro-cylinder energy storage at endless rope winch head roll rear.After steel rope 7 generation is lax, slack can reach rapidly head roll front, steel rope 7 tensile force at movable pulley 4 place reduces, auxiliary compressed oil cylinder 2 can carry out contraction piston rod under the effect of energy storage, the related movable pulley 4 of piston rod moves, and movable pulley 4 produces displacement relative to the first fixing fixed pulley 5 and the second fixed pulley 6, above carries steel rope 7, thus absorb rapidly the slack of steel rope 7, ensure the safe handling of endless rope winch.
Auxiliary compressed oil cylinder 2 is cascaded with the energy storage of tightening device, carry out work under auxiliary compressed oil cylinder 2 is in same pressure condition with the tensioning hydro-cylinder of tightening device under the effect of energy storage, after auxiliary compressed oil cylinder 2 action, finally meeting and the whole clamping system of endless rope winch reach the state of balance.
