To improve the safety and efficiency of belt conveyors in inclined shafts, technicians in this field urgently need a safety device for transporting water and coal on inclined shaft belt conveyors. Based on the existing belt conveyor, a large, direct-lap belt-pressing and anti-slip device has been designed to effectively address this belt slippage issue. Utility Model Content

[0003] The utility model aims to provide a safety protection device for water-coal transportation of an inclined shaft belt conveyor, which solves the problem of the belt sliding down when the belt stops.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The utility model discloses a safety protection device for water-coal transportation of an inclined shaft belt conveyor, comprising a protection frame assembly, two opposite protection frame assemblies respectively located on both sides of the belt, the bottom of the protection frame assembly being connected to the channel steel on the belt conveyor, and a plurality of protection frame assemblies being arranged along the extending direction of the belt;

[0006] The protective frame assembly includes a support frame, a skirt, a vertical belt, a bent plate, a plywood 1 and a plywood 2. The channel steel is connected to the bottom of the support frame, and a bent plate is welded to the top of the support frame. The top end of the skirt is connected to the support frame through the plywood 2, and the bottom end of the skirt contacts one side of the upper surface of the belt. The top end of the vertical belt is connected to the bent plate through the plywood 1, and the bottom end of the vertical belt contacts the upper surface of the skirt.

[0007] Preferably, the support frame includes angle steel 1 and angle steel 2, the top end of angle steel 2 is connected to the middle part of angle steel 1, a bent plate is welded to the top of angle steel 1, a hoop sub-plate is welded to the bottom end of angle steel 2, the outer sleeve of the channel steel is provided with a hoop mother plate, and a bolt assembly connects the hoop sub-plate, the hoop mother plate and angle steel 2 together.

[0008] Preferably, the second clamping plate, the top end of the skirt and the bottom end of the first angle steel are all provided with through holes, and the second clamping plate, the top end of the skirt and the bottom end of the first angle steel are connected together by a bolt assembly.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are:

[0012] (1) The utility model relates to a safety protection device for water-coal transportation on an inclined shaft belt conveyor. Since the vertical belt, skirt and belt are in contact with each other, when transporting water-coal and gangue, only the uncontacted part of the belt is used to transport the water-coal and gangue, and the remaining water-coal and gangue remain on the skirt and generate positive pressure on the belt, so that friction is generated between the vertical belt, skirt and belt, and friction is also generated between the moving coal and the stationary coal. When the components driving the belt stop running, the belt stops moving in time by relying on the friction between the belt and the vertical belt, skirt and the friction between the coal, so that the belt does not automatically slide down or fly away when it stops.

[0013] (2) The utility model is suitable for the use of belt conveyors in inclined shaft environments. By arranging a large surrounding protective structure on the belt, it can effectively prevent the belt from slipping when it is wet or the load is large, ensuring the continuous and stable operation of the conveying system, effectively improving the operating safety and efficiency, and solving the safety protection problem of inclined shaft belt conveyors in special environments.

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] like Figure 1-2 As shown, a safety protection device for water-coal transportation on an inclined shaft belt conveyor includes a protection frame assembly, two opposing protection frame assemblies are respectively located on both sides of a belt 5, the bottom of the protection frame assembly is connected to the channel steel 4 on the belt conveyor, and multiple protection frame assemblies are provided along the extension direction of the belt 5;

[0020] The protective frame assembly includes a support frame 3, a skirt 6, a vertical belt 10, a bent plate 9, a splint 1 7 and a splint 2 11. The channel steel 4 is connected to the bottom of the support frame 3. The top of the support frame 3 is welded with a bent plate 9. The top of the skirt 6 is connected to the support frame 3 through the splint 2 11. The bottom end of the skirt 6 contacts one side of the upper surface of the belt 5. The top end of the vertical belt 10 is connected to the bent plate 9 through the splint 1 7. The bottom end of the vertical belt 10 contacts the upper surface of the skirt 6.

[0021] Specifically, the channel steel 4 is a belt roller support frame on the belt conveyor.

[0022] Specifically, a clamping plate 7 is used to connect the vertical belt 10 and the bending plate 9 together to prevent the vertical belt from being squeezed out of the protective frame assembly when transporting gangue.

[0023] Specifically, the working principle of this protective device is that because the vertical belt 10 and the skirt are in contact with the belt 5, when transporting coal and gangue, only the untouched middle portion of the belt 5 is used to carry the coal and gangue. The remaining coal and gangue remain on the skirt 6 and exert positive pressure on the belt 5, causing friction between the vertical belt 10, the skirt 6, and the belt 5, as well as friction between the moving coal and the stationary coal. When the components driving the belt stop operating, the friction between the belt 5 and the vertical belt 10 and the skirt 6, as well as the friction between the coal, stops the belt 5 in a timely manner, preventing the belt from automatically sliding down or running away when it stops.

[0024] The support frame 3 includes an angle steel 1 31 and an angle steel 2 32. The top of the angle steel 2 32 is connected to the middle of the angle steel 1 31. A bent plate 9 is welded to the top of the angle steel 1 31. The bottom of the angle steel 2 32 is welded to the hoop sub-plate 2. The channel steel 4 is covered with a hoop mother plate 1. A bolt assembly connects the hoop sub-plate 2, the hoop mother plate 1, and the angle steel 2 32. Specifically, the top of the angle steel 2 can be connected to the middle of the angle steel 1 by welding or bolts.

[0025] The second clamping plate 11, the top end of the skirt 6 and the bottom end of the angle steel 31 are all provided with through holes, and the bolt assembly connects the second clamping plate 11, the top end of the skirt 6 and the bottom end of the angle steel 31 together.

[0026] The clamping plate 1 7 , the top end of the vertical belt 10 and the bent plate 9 are all provided with through holes, and the bolt assembly connects the clamping plate 1 7 , the top end of the vertical belt 10 and the bent plate 9 together.

[0027] The side walls of the two opposite bent plates 9 are connected by bolts with a pull rod 8. The pull rod is used to improve the stability of the entire device.

[0028] The use process of this utility model is as follows:

[0029] The device is installed on the belt conveyor so that the two opposite protective frame assemblies are respectively located on both sides of the belt 5, the bottom of the protective frame assembly is connected to the channel steel 4 on the belt conveyor, and multiple protective frame assemblies are arranged along the extending direction of the belt 5;

[0030] Because the vertical belt 10 and the skirt are in contact with the belt 5, when transporting coal and gangue, only the untouched middle portion of the belt 5 is used to carry the coal and gangue. The remaining coal and gangue remain on the skirt 6, exerting positive pressure on the belt 5. This creates friction between the vertical belt 10, the skirt 6, and the belt 5, as well as between the moving coal and the stationary coal. When the components driving the belt stop operating, the friction between the belt 5, the vertical belt 10, the skirt 6, and the coal itself acts together to stop the belt 5 in a timely manner, preventing the belt from automatically sliding down or running away when it stops.
