Description

Technical Field

[0001] This utility model relates to the field of vehicle body covering technology, specifically a covering structure for mining truck transportation. Background Technology

[0002] Open-pit mines and large coal storage yards generally use 80t to 400t mining trucks for short-haul transportation of raw coal and stripping materials. In order to suppress dust and prevent coal dust from spilling, tarpaulins are needed for covering. In the existing technology, most of the tarpaulin installation is done manually. Although the above-mentioned devices are used to manually cover ordinary canvas or PE tarpaulin, manual installation is labor-intensive and takes a long time to seal the vehicle. In addition, there is no active pressing mechanism. When the vehicle moves, a negative pressure area is formed on the upper surface of the tarpaulin, which can easily cause the edges of the tarpaulin to tear or bulge, making the tarpaulin less stable during use. Utility Model Content

[0003] The purpose of this utility model is to provide a covering structure for mining truck transportation to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A mining truck transport cover structure includes a bracket installed on the front and rear surfaces of the truck body. A cover is fixedly connected to the front surface of the bracket, a first integrated motor reducer is fixedly connected to the rear surface of the cover, a second integrated motor reducer is fixedly connected to the rear surface of the cover, a take-up roller is fixedly connected to the output end of the first integrated motor reducer, and a take-up shaft is fixedly connected to the output end of the second integrated motor reducer. The front and rear surfaces of the truck body are equipped with a laying mechanism, which includes an n-shaped frame, a first guide pulley, a second guide pulley, a roller, and a mounting frame. The n-shaped frame is fixedly connected to the front and rear surfaces of the truck body. The first guide pulley is rotatably connected to the side surface of the n-shaped frame. The second guide pulley is rotatably connected to the inner surface of the n-shaped frame. The roller is rotatably connected to the lower surface of the n-shaped frame. The mounting frame is fixedly connected to the inner surface of the n-shaped frame. The inner surface of the mounting frame is rotatably connected to the second pulley. The inner surface of the mounting frame is fixedly connected to a blocking frame.

[0005] Furthermore, a steel wire rope is wound around the outer surface of the second pulley, one end of the steel wire rope passes over the first guide pulley and is fixedly connected to the winding roller, the other end of the steel wire rope passes over the second guide pulley and is fixedly connected to the winding shaft, and a flexible wear-resistant tarpaulin is fixedly connected to the outer surface of the steel wire rope.

[0006] Furthermore, a winding wheel is fixedly connected to the outer surface of the winding shaft and the corresponding position of the wire rope.

[0007] Furthermore, a pressing mechanism is fixedly connected to the side surface of the cover. The pressing mechanism includes a mounting frame, a mounting box, and a horizontal plate. The mounting frame is fixedly connected to the side surface of the cover, the mounting box is fixedly connected to the upper surface of the mounting frame, and the horizontal plate is fixedly connected to the lower surface of the mounting box. An energy storage power source is fixedly connected to the upper surface of the horizontal plate, and a controller is fixedly connected to the upper surface of the horizontal plate.

[0008] Furthermore, an electric push rod is fixedly connected to the upper surface of the horizontal plate, a lower pressure frame is fixedly connected to the output end of the electric push rod, and an extrusion roller is rotatably connected to the inner surface of the lower pressure frame.

[0010] Furthermore, L-shaped plates are fixedly connected to both the front and rear surfaces of the truck body, and bolts are threaded onto the outer surface of the L-shaped plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The wear-resistant tarpaulin is fixed to the outer surface of the steel wire rope by rivets or stitching to form a retractable structure. When the winding roller unwinds and the winding shaft winds up, the steel wire rope drives the wear-resistant tarpaulin to move along the U-shaped trajectory formed by the first guide pulley, the second guide pulley and the second pulley, to achieve full coverage of the truck bed roof. Conversely, the wear-resistant tarpaulin and steel wire rope are stored away, improving the efficiency of laying the wear-resistant tarpaulin. 2. The extrusion rollers press the windward side of the wear-resistant tarpaulin against the upper edge of the truck bed, reducing windward bulges. The outer surface of the extrusion rollers is covered with a rubber layer, which ensures sufficient friction while preventing scratches on the wear-resistant tarpaulin. Limiting rods are provided on both sides of the lower pressure frame, which cooperate with the holes on the lower surface of the horizontal plate to achieve lifting guidance. The vertical section of the L-shaped plate has screw holes. The bolts cooperate with the screw holes to press the outer surface of the wear-resistant tarpaulin, making it tightly connected to the n-shaped frame. During operation, it prevents lateral air intake and makes the wear-resistant tarpaulin more stable when covering the tarpaulin. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 In this embodiment of the utility model, a mining truck transport cover structure includes a bracket 5 installed on the front and rear surfaces of the truck body 1. A cover 501 is fixedly connected to the front surface of the bracket 5. A first integrated motor reducer 502 is fixedly connected to the rear surface of the cover 501. A second integrated motor reducer 503 is fixedly connected to the rear surface of the cover 501. A take-up roller 504 is fixedly connected to the output end of the first integrated motor reducer 502. A take-up shaft 505 is fixedly connected to the output end of the second integrated motor reducer 503. The front and rear surfaces of the truck body 1 are provided with a laying mechanism 2. The laying mechanism 2 includes an n-shaped frame 207, a first guide pulley 201, a second guide pulley 202, a roller 203, and a mounting frame 204. The n-shaped frame 207 is fixedly connected to the front and rear surfaces of the truck body 1. The first guide pulley 201 is rotatably connected to the side surface of the n-shaped frame 207. The second guide pulley 202 is rotatably connected to the inner surface of the n-shaped frame 207. The roller 203 is rotatably connected to the lower surface of the n-shaped frame 207. The mounting frame 204 is fixedly connected to the inner surface of the n-shaped frame 207. The inner surface of the mounting frame 204 is rotatably connected to a second pulley 205. The inner surface of the mounting frame 204 is fixedly connected to a blocking frame 206.

[0016] Specifically, during use, starting the No. 1 integrated motor reducer 502 drives the take-up roller 504 to rotate, and the No. 2 integrated motor reducer 503 drives the take-up shaft 505 to rotate. During laying, the take-up roller 504 unwinds, and the take-up shaft 505 winds up, laying the wear-resistant tarpaulin 4 on the upper surface of the truck bed 1 to cover the coal inside the truck bed 1. The first guide pulley 201 and the second guide pulley 202 guide the wire rope 3 and the wear-resistant tarpaulin 4 connected to the wire rope 3. The second pulley 205 acts as a fixed pulley, changing the direction of movement of the wire rope 3, making the movement path of the wire rope 3 U-shaped. The roller 203 reduces the friction between the wear-resistant tarpaulin 4 and the n-shaped frame 207. The winding path of the wear-resistant tarpaulin 4 is as follows: Figure 2 As shown, the blocking frame 206 shields the mounting frame 204, preventing coal from entering the interior of the n-shaped frame 207 when the truck bed 1 is tilted to unload.

[0017] Example 1 like Figure 1-4 As shown, a steel wire rope 3 is wound around the outer surface of the second pulley 205. One end of the steel wire rope 3 passes around the first guide pulley 201 and is fixedly connected to the winding roller 504. The other end of the steel wire rope 3 passes around the second guide pulley 202 and is fixedly connected to the winding shaft 505. A flexible wear-resistant tarpaulin 4 is fixedly connected to the outer surface of the steel wire rope 3.

[0018] In this embodiment, the wear-resistant tarpaulin 4 is fixed to the outer surface of the steel wire rope 3 by rivets or stitching to form a retractable structure. When the winding roller 504 unwinds and the winding shaft 505 winds up, the steel wire rope 3 drives the wear-resistant tarpaulin 4 to move along the U-shaped trajectory formed by the first guide pulley 201, the second guide pulley 202 and the second pulley 205, so as to achieve full coverage of the top surface of the truck bed 1. Conversely, the wear-resistant tarpaulin 4 and the steel wire rope 3 are stored away, thereby improving the efficiency of laying the wear-resistant tarpaulin 4.

[0019] like Figure 1-4 As shown, the reel is 505.

[0020] like Figure 1-4 As shown, a winding wheel 506 is fixedly connected to the outer surface of the winding shaft 505 and the corresponding position of the wire rope 3.

[0021] In this embodiment, the take-up reel 506 provides auxiliary limiting for the wire rope 3, so that the wire rope 3 is located inside the take-up reel 506 after being wound up.

[0022] Example 2 Based on Example 1, in order to overcome the problem that it is inconvenient to limit the windward side of the wear-resistant tarpaulin 4 in Example 1.

[0023] like Figure 1-4As shown, a pressing mechanism 6 is fixedly connected to the side surface of the cover 501. The pressing mechanism 6 includes a mounting frame 601, a mounting box 602, and a horizontal plate 603. The mounting frame 601 is fixedly connected to the side surface of the cover 501, the mounting box 602 is fixedly connected to the upper surface of the mounting frame 601, the horizontal plate 603 is fixedly connected to the lower surface of the mounting box 602, the energy storage power supply 604 is fixedly connected to the upper surface of the horizontal plate 603, the controller 605 is fixedly connected to the upper surface of the horizontal plate 603, and the electric push rod 606 is fixedly connected to the upper surface of the horizontal plate 603. In this embodiment, the energy storage power supply 604 is a lithium battery pack, which is connected to the controller 605 and the electric push rod 606 through the battery plate, wires and wires. The push rod of the electric push rod 606 extends at a constant speed until the extrusion roller 608 presses the windward side of the wear-resistant tarpaulin 4 against the upper edge of the truck bed 1 to reduce windward bulging.

[0024] like Figure 1-4 As shown, the output end of the electric push rod 606 is fixedly connected to the lower pressure frame 607, the inner surface of the lower pressure frame 607 is rotatably connected to the extrusion roller 608, the lower pressure frame 607 and the cross plate 603 are slidably connected, the extrusion roller 608 is in contact with the wear-resistant tarpaulin 4, the front and rear surfaces of the truck body 1 are fixedly connected to the L-shaped plate 7, and the outer surface of the L-shaped plate 7 is threaded with bolts 701.

[0025] In this embodiment, the outer surface of the extrusion roller 608 is covered with a rubber layer, which ensures sufficient friction and avoids scratching the wear-resistant tarpaulin 4. The lower pressure frame 607 is provided with limit rods on both sides, which cooperate with the holes on the lower surface of the horizontal plate 603 to realize lifting and guiding. The vertical section of the L-shaped plate 7 has screw holes, and the bolts 701 cooperate with the screw holes to press the outer surface of the wear-resistant tarpaulin 4, so that it is tightly connected with the n-shaped frame 207, preventing side air intake and making the wear-resistant tarpaulin 4 more stable when covering.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
