Description

Technical Field

[0001] This utility model relates to a coal pile covering traction device. Background Technology

[0002] Due to environmental protection requirements, open-pit coal yards in China must take measures to prevent coal dust from damaging the environment. Covering the coal pile with rainproof and dustproof tarpaulins is the most common technical measure. Currently, mechanical tarpaulin covering devices are used. The rainproof and dustproof tarpaulin is connected to the rope on the winch. The tarpaulin is covered over the coal pile by the rope when the winch is turned on. However, when the tarpaulin reaches the outer side of the top of the coal pile, it will be subjected to horizontal tension and get stuck on the top of the coal pile, creating resistance. This prevents the tarpaulin from getting over the top of the coal pile. At this time, workers need to climb up and down the coal pile to manually intervene and pull the tarpaulin out of the stuck area. This increases the workload, reduces work efficiency, increases work intensity, and poses high safety risks. Utility Model Content

[0003] The purpose of this invention is to provide a coal pile covering traction device that solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model employs the following technical solution: A coal pile covering traction device comprises a front axle and a rear axle. At least five front support wheels are connected to the front axle, and a plurality of rear support wheels corresponding to the number of front support wheels are connected to the rear axle. A bearing is connected between two adjacent front support wheels, and a collar is fixed to the outside of the bearing. Two of the collars are fixed to one end of a connecting rod, and the other end of the connecting rod is fixed to the rear axle. The collars of the other two bearings are fixed to the hanging rings.

[0005] In the aforementioned coal pile covering traction device, multiple support rods are threaded between the two connecting rods, and multiple pillars are fixed on the support rod at the first end.

[0006] In the aforementioned coal pile covering traction device, both the front support wheel and the rear support wheel are rubber wheels.

[0007] The aforementioned coal pile covering traction device, wherein the connecting rod is a type of rod. Beneficial effects

[0008] 1. This utility model is a traction device. The canvas is hung on the support of the traction device. The front end of the canvas is lifted by the traction device, which avoids the situation where the canvas is easily pressed down by coal when it reaches the top of the coal pile due to the resistance generated. This reduces the labor intensity of the workers, improves the work efficiency, and avoids the danger of workers climbing up and down the coal pile in extreme weather conditions, thus ensuring the safety of the workers.

[0009] 2. By setting up a connecting rod, this utility model ensures that the front end of the canvas is always higher than the coal pile at the turning points between the front and top sides and between the top and rear sides of the canvas during movement, thus preventing the canvas from sinking into the coal pile due to changes in the direction of tension when turning.

[0010] 3. This utility model can support the front end of the canvas by inserting multiple support rods between the two connecting rods, preventing the middle of the canvas from collapsing and falling into the coal pile during the pulling process, thus affecting the coverage.

[0012] Please see Figures 1 to 4 A coal pile covering traction device comprises a front axle 8 and a rear axle 5. At least five front support wheels 7 are connected to the front axle, and multiple rear support wheels 2 corresponding to the number of front support wheels are connected to the rear axle. Both the front and rear support wheels are rubber wheels. A bearing 13 is connected between two adjacent front support wheels. Both the front and rear support wheels are limited by cotter pins. A collar 12 is fixed to the outside of the bearing. The inner ring of the bearing is fixed to the front axle, and the outer ring of the bearing is fixed to the collar. Two of the collars are fixed to one end of a connecting rod 1, and the other end of the connecting rod is fixed to the rear axle. The collars of the other two bearings are fixed to the hanging ring 3.

[0013] In the coal pile covering traction device, multiple support rods 6 are passed between the two connecting rods, and multiple pillars 4 are fixed on the support rod at the first end. The multiple support rods are fixed to the connecting rod. The aforementioned coal pile covering traction device, wherein the connecting rod is a type of rod.

[0014] Working principle: Refer to Figures 5-7 First, hang one end of the canvas on the support pole. Then, tie the rope of the winch 14 to the hanging ring. When the winch starts, pull the rope to move the traction device, gradually covering the coal pile 10 with the canvas 9. At the turning point between the front and top of the canvas, due to the horizontal tension, the front support wheel supports the top of the coal pile, and the rear support wheel supports the front of the coal pile, thus ensuring that the traction device continuously supports the canvas, keeping the front end of the canvas higher than the coal pile and preventing the canvas from being pulled at the turning point. The canvas shifts direction and sinks into the coal pile. Simultaneously, multiple support rods are fixed between the two connecting rods to support the front end of the canvas, preventing it from collapsing in the middle and sinking into the coal pile during pulling, thus affecting coverage. At the turn between the top and rear, a downward pulling force is applied. Through the rotation of the connecting rods, the front support wheel supports the rear of the coal pile, and the rear support wheel supports the top. This ensures the traction device continuously supports the canvas, keeping the front end of the canvas higher than the coal pile, preventing the canvas from sinking into the coal pile when the pulling force changes direction at the turn.
