Utilize the grooving to increase the interior edge that the friction pulley has been increased to the device, effectively solved the problem that a friction pulley that rises because of wire rope is loose damaged equipment, spacing protection device is adopted, the disconnected rope accident of wire rope because of pulling the big initiation of frictional force can be effectively avoided.
Description
Technical field
The utility model belongs to the technical field of mining car pusher hoist redution gear, is specifically related to a kind of car pusher winch friction wheel fender guard.
Background technology
Car pusher winch mainly relies on retarder friction wheel lay winding wire ropes to carry out towing vehicle, in grooving formula friction wheel, outer is relatively shallow with the friction wheel without grooving, time as little in normal traction resistance, steel rope then can not depart from grooving, but in actual use, there is car brakeing wind and do not put or do not drain the problem causing friction drag large, steel rope between the friction wheel of main gear side occurs that because friction force is large pine is risen phenomenon, and along more shallow in friction wheel, the steel rope that pine is risen will depart from grooving, will draw bad retarder.Therefore safety requirements when the former specification of equipment that dispatches from the factory can not meet routine use.Increase the height of outer in friction wheel, there is the excessive potential safety hazard breaking steel rope of friction drag equally, need initiatively to avoid the excessive harm caused of friction force.
Summary of the invention
The utility model in order to solve grooving formula friction wheel self Problems existing, avoid equipment be in operation exist hidden danger, provide a kind of car pusher winch friction wheel fender guard.
The utility model adopts following technical scheme:
A kind of car pusher winch friction wheel fender guard; the limiting and protecting device comprising two groups of grooving heightening devices and be located between two groups of grooving heightening devices; two groups of grooving heightening devices respectively correspondence are located at two friction wheel places; described each grooving heightening device comprises and is vertically fixed on ground two blocks of vertical supporting plates; friction wheel is placed between two blocks of vertical supporting plates, and the upper surface of vertical supporting plate is higher than the upper wheel rim of friction wheel.
Described limiting and protecting device comprises cross-tie plate; the two ends of cross-tie plate are connected with two groups of grooving heightening devices respectively; the stage casing of cross-tie plate is connected with vertical pipe; Contact plate is provided with in pipe; the top of Contact plate is provided with limit relay switch, and limit relay switch wire connection is to the control loop line point in friction wheel variable frequency control case.
Described cross-tie plate and grooving heightening device are for being flexibly connected, and junction is provided with height adjustment bolt.
The height of described cross-tie plate is greater than the height of the steel rope be wound on two friction wheels.
The utility model has following beneficial effect:
1, the utility model is in the original structure situation not destroying friction wheel, grooving heightening device is utilized to increase the interior edge of friction wheel, when steel rope occur pine rise phenomenon time, more loose steel rope can not drop out friction wheel grooving, efficiently solves because steel rope pine is risen and drops out the problem of friction wheel damage equipment;
2, the utility model have employed limiting and protecting device, rise to upwarp when steel rope pine and touch limit switch, send emergent stop signal in variable frequency control case to motor, make motor stop action, car pusher winch disconnects forward travel action, avoids steel rope because of the rope-broken accident of the large initiation of traction friction force;
3, described limiting and protecting device also can be used on similar retarder, effectively can avoid the accident that the steel rope caused because friction force is excessive is pulled off.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-vertical supporting plate, 2-pipe, 3-Contact plate, 4-limit relay switch, 5-steel rope, 6-friction wheel, 7-angle bar, 8-cross-tie plate.
Detailed description of the invention
By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:
Car pusher winch friction wheel fender guard as shown in the figure; the limiting and protecting device comprising two groups of grooving heightening devices and be located between two groups of grooving heightening devices; two groups of grooving heightening devices respectively correspondence are located at two friction wheel 1 places; described each grooving heightening device comprises and is vertically fixed on ground two blocks of vertical supporting plates 1; friction wheel 6 is placed between two blocks of vertical supporting plates 1, and the upper surface of vertical supporting plate 1 is higher than the upper wheel rim of friction wheel 6.
The utility model has installed two fender guards on friction wheel:
1. on retarder side two friction wheels, physical protection one is installed respectively additional, namely the steel plate (vertical supporting plate) using two pieces of 8mm thick is close to outer in friction wheel and is vertically put in ground, two pieces of angle bar are fixed respectively at ground expansion bolt, by angle bar and vertical Plate Welding, needs more change steel rope or other maintenance time, can be pulled down, Plate Welding is used equally in two pieces of vertical steel plate tops, form the environment of a closed friction wheel grooving, the upper surface of vertical supporting plate is higher than the upper wheel rim of friction wheel, be equivalent to increase edge in friction wheel, play a protective role.
2., after protecting one to complete, between two protection one top steel plates, one piece of 6mm plate iron (cross-tie plate) is fixed again with screw, can the position of this steel plate of up-down adjustment by governing screw place nut, make limit switch more flexible.Punch in this steel plate middle; weld a pipe; make Contact plate, put it in pipe, at touching version tip position; a limit switch is fixed in installation; limit switch is wired to the control loop line point in variable frequency control case, and after limit switch is touched, control loop stops action to motor is anxious; protection steel rope, easily and effectively.
Car pusher winch can avoid steel rope to drop out friction wheel after installing above-mentioned two protections, then makes retarder be drawn bad, the accident that steel rope is pulled off.This protection is fairly simple, maintains easily, and effectively can improve the safety of car pusher winch, reaches intrinsically safe equipment.
