Abstract

The utility model discloses a kind of position limitation protection structure of endless rope winch tightening device, this position limitation protection structure comprises winch take-up device, and four travel switches and bracing or strutting arrangement thereof.Four travel switches are separately fixed at by bracing or strutting arrangement the lower limit that the major and minor rope of winch take-up device stresses to hammer into shape, and by junction circuit parallel connection access PLC control cabinet.Be obstructed when advancing if there is vehicle, when stop device is not opened, vehicle slides down, haulage cable tensile force is caused to change violent, the major and minor rope of tightening device stresses one of hammer and drops rapidly, weight glides and triggers travel switch, by the control loop report tightening device limit switch fault of circuit ON winch after travel switch action, winch stall, reduces equipment damage and loss.The utility model structure is simple, easy to use, without the need to transforming existing tightening device remainder.

Description

A kind of position limitation protection structure of endless rope winch tightening device
Technical field
The utility model relates to a kind of position limitation protection structure, particularly a kind of position limitation protection structure of endless rope winch tightening device.
Background technology
Endless rope winch be coal mine down-hole tunnel with a kind of rail-based conveyor system of rope traction, mainly contain the compositions such as winch, tightening device, traction shuttle car, tail wheel, wheels.The part that tightening device Absorbable rod haulage cable system is extended due to elastic deformation, ensures that haulage cable is lining with more stable positive pressure at barrel rope, impel winch normally to draw, and unlikely haulage cable skids on barrel.This device is primarily of compositions such as framework 1, tight pulley 3, loose wheel 4, track adjusting wheel 2, sheave 5, weight 6 and grille guards.Tightening device divides major and minor rope side, is respectively made up of three tight pulleys, two loose wheels, two track adjusting wheels, two sheaves, two weights.Haulage cable enters from front end, tightening device main rope side sheave, enters tight pulley successively, loose wheel, tight pulley, loose wheel, tight pulley, after winch capstan, passes from tightening device pair rope front end, side sheave.For wherein side, wherein two loose wheels are connected with weight with steel rope respectively by suspension ring, and steel wire hang is in the track adjusting wheel at tightening device top.In winch operational process, when the tensile force of haulage cable reduces, because weight Action of Gravity Field makes weight walk around the track adjusting wheel at shelf top by steel rope, loose wheel is affected upwards to move about, otherwise, when the tensile force of haulage cable raises, haulage cable tensile force hauls loose wheel and declines, and loose wheel drives weight to raise by steel rope.Under normal circumstances, tightening device major and minor stresses to hammer into shape sliding up and down within the scope of downward 1.1 meters of vertex by a small margin.Endless rope winch is in operational process, if there is vehicle advance be obstructed, the situation such as stop device is not opened, vehicle slides down time, the main rope of haulage cable is caused to be stuck, and cylinder is rotated further, make haulage cable tensile force change near tightening device violent, tightening device side weight rises rapidly, and opposite side drops rapidly.If now run rider does not propaganda directed to communicate parking in time, and the non-Timeliness coverage exception parking of driver continues to drive, and can cause vehicle, the equipment of breaking, and haulage cable is impaired etc. makes fault spread.
Summary of the invention
The purpose of this utility model is, provides a kind of position limitation protection structure of endless rope winch tightening device, avoids the impact that endless rope winch machinery and electrical accident cause equipment, the simple and effective protection achieved equipment simultaneously.
Technical solution of the present utility model is:
The utility model provides a kind of position limitation protection structure of endless rope winch tightening device, and this position limitation protection structure comprises: winch take-up device, four travel switches and bracing or strutting arrangement thereof.Feature is: four travel switches are separately fixed at by bracing or strutting arrangement the lower limit that the major and minor rope of winch take-up device stresses to hammer into shape two ends, and by junction circuit parallel connection access PLC control cabinet.
Further, described bracing or strutting arrangement is adjustable-height supporting seat.
Be obstructed when advancing if there is vehicle, when stop device is not opened, vehicle slides down, haulage cable tensile force is caused to change violent, one of tightening device major-minor weight drops rapidly, weight glides and triggers travel switch, by the control loop report tightening device limit switch fault of circuit ON winch after travel switch action, winch stall.
The utility model compared with prior art has following obvious advantage: the utility model is arranged on tightening device weight lower limit place, and structure is simple, easy to use, without the need to transforming existing tightening device remainder.And height can be adjusted in real time according to the change of weight lower limit.When endless rope winch transportation system goes wrong, trigger this device by tightening device weight, winch is out of service, reduces equipment damage, increases the system cloud gray model safety of endless rope winch further.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the stepless rope winch system birds-eye view comprising tightening device;
In figure, 1-tensioner frame, 2-track adjusting wheel, 3-loose wheel, 4-tight pulley, 5-rear end sheave, 6-weight, 7-travel switch, 8-bracing or strutting arrangement, 9-front end sheave, 10-winch, 11-tightening device, 12-traction shuttle car, 13-haulage cable.
Detailed description of the invention
Detailed description of the invention of the present utility model is introduced further below in conjunction with accompanying drawing:
As shown in Figure 1, the position limitation protection structure of this endless rope winch tightening device comprises: winch take-up device, four travel switches 7 and bracing or strutting arrangement 8 thereof.
Winch take-up device comprises main rope side and secondary rope side, wherein side is containing three tight pulleys, 4, two loose wheels, 3, two track adjusting wheels, 2, two weights 6, haulage cable 13 enters from Zhu Sheng side, tightening device front end sheave 9, successively by tight pulley 4, loose wheel 3, tight pulley 4, loose wheel 3 and tight pulley 4, pass from tightening device pair rope rear flank end sheave 5, after winch 10 capstan, equally successively by tight pulley 4, loose wheel 3, tight pulley 4, loose wheel 3 and tight pulley 4, then pass from tightening device pair rope front end, side sheave 9.In its side, two loose wheels 3 are connected with weight 6 with suspension ring respectively by steel rope, and steel wire hang is in the track adjusting wheel 2 at tightening device top, and the wheel shaft of loose wheel 3 can move up and down along the guide groove of this loose wheel in tensioner frame 1.Travel switch 7 is separately fixed at by bracing or strutting arrangement 8 lower limit that the major and minor rope of winch take-up device stresses hammer 6 two ends, four travel switches 7 by junction circuit parallel connection access PLC control cabinet;
Bracing or strutting arrangement 8 can be fixed in tensioner frame 1, also can be adjustable-height supporting seat.
Be obstructed when advancing if there is winch, when stop device is not opened, winch slides down, haulage cable 13 tensile force is caused to change violent, loose wheel 3 moves up along the guide groove of this loose wheel in tensioner frame 1, the major and minor rope of tightening device stresses one of hammer 6 and drops rapidly, weight 6 glides and triggers travel switch 7, by the control loop report tightening device limit switch fault of circuit ON winch after travel switch 7 action, winch 10 stall.
