A. be fixed on perpendicular again, S. A. is also vertically connected with limit shaft, main shaft frame is also provided with limit sensors, limit sensors is installed on belt support frame, limit shaft is connected with limit sensors, limit sensors is connected with controller, it is aging or come off and be difficult to be found and cause spreading the problem of the breakdown of machinery such as coal that the utility model solves the main shaft belt existed in prior art.
Description
Technical field
The utility model belongs to field of electromechanical technology, is specifically related to a kind of belt tear-preventing fender guard.
Background technology
Main shaft belt is in aging period, and often occur that rubber comes off, even belt tearing and coal piling spill coal phenomenon.Because belt running velocity is high, personnel cannot Timeliness coverage shutting down, and easily make fault spread, reduce belt Homes Using TV, prolongation is mistaken, and affects raw coal transportation.
Utility model content
The purpose of this utility model is to provide a kind of belt tear-preventing fender guard, solves the main shaft belt existed in prior art aging or come off and be difficult to be found and cause spreading the problem of the breakdown of machinery such as coal.
The technical scheme that the utility model adopts is, a kind of belt tear-preventing fender guard, comprise the trapezoidal load-bearing frame be arranged on main shaft below belt, load-bearing frame opening is relative with belt on main shaft, load-bearing frame bottom is also connected with bearing box, be connected with bearing plate bottom bearing box, distance equidistant position, bearing plate center, bearing plate two ends such as to be respectively arranged with at the weight, wherein the weight that waits of one end is connected with the S. A. be fixed on perpendicular again, S. A. is also vertically connected with limit shaft, main shaft frame is also provided with limit sensors, limit shaft is connected with limit sensors, limit sensors is connected with controller.
Feature of the present utility model is also,
Limit sensors is installed on belt support frame.
Bearing plate length is greater than bearing box and the bearing plate contact surface length of side.
The beneficial effects of the utility model are; a kind of belt tear-preventing fender guard; by the weight such as to arrange at bearing plate two ends; utilize the counterweight balance principles such as two ends and then driven rotary axle to make limit sensors send signal to controller, according to limit sensors signal, controller just can judge that main shaft belt has and do not tear or or occur spreading the phenomenon of coal.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of belt tear-preventing fender guard of the utility model.
In figure, 1. load-bearing frame, 2. bearing box, 3. bearing plate, 4. weight such as grade, 5. S. A., 6. limit shaft, 7. limit sensors, 8. controller.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of belt tear-preventing fender guard of the utility model, as shown in Figure 1, comprise the trapezoidal load-bearing frame 1 be arranged on main shaft below belt, load-bearing frame 1 opening is relative with belt on main shaft, bearing box 2 is also connected with bottom load-bearing frame 1, be connected with bearing plate 3 bottom bearing box 2, bearing plate 3 length is greater than bearing box 2 and the bearing plate 3 contact surface length of side, equal position, distance bearing plate 3 center, bearing plate 3 two ends such as to be respectively arranged with at the weight 4, wherein the weight 4 that waits of one end is connected with the S. A. 5 be fixed on perpendicular again, S. A. 5 is also vertically connected with limit shaft 6, main shaft frame is also provided with limit sensors 7, specifically, limit sensors 7 is installed on belt support frame, limit shaft 6 is connected with limit sensors 7, limit sensors 7 is connected with controller 8.
A kind of belt tear-preventing fender guard of the utility model, when main shaft belt tearing or upper belt spill coal occur spreading coal situation time, coal will be had to drop in load-bearing frame 1, because load-bearing frame 1 is designed to trapezoidal, can prevent the coal scattered from continuing to fall further, load-bearing frame 1 finally enters bearing box 2, at this moment bearing plate 3 meeting run-off the straight under the Action of Gravity Field of coal, the weight 4 that waits at bearing plate 3 two ends there will be one high and one low situation, be connected with S. A. 5 again owing to waiting weight 4, so wait the change in location of weight 4 and then can rotate by driven rotary axle 5, again because the limit shaft 6 on S. A. 5 is connected with limit sensors 7, drive limit shaft rotates, make spacing instrument action, so final limit sensors 7 can collect and the most originally spread coal signal, thus make controller 8 send halt command, equally, when main belt rubber decortication, bearing plate 3 is tilted, driven rotary axle 5 rotates, make limit sensors 7 action, realize shutting down.
The utility model makes to run in work when tearing appears in main belt, when decortication and coal piling spill coal, can realize timely shutdown, and avoid accident or hidden danger to expand, reduce loss, reduction is mistaken, and ensure that the transport of raw coal.
