Description

Technical Field

[0001] The invention relates to a belt pressing device for a belt conveyor, belonging to the technical field of belt conveyors. Background Art

[0002] Belt conveyors are widely used in coal mines to transport coal. In most transportation routes, especially in the transportation tunnels in the mining operation area, these tunnels are not completely flat due to the diversity of tunnel terrain and irregular inclination. The conveyor belt must adapt to these changes and is often in a non-horizontal state. Some sections of the conveyor belt even have a significant inclination angle, and the part of the conveyor belt in the climbing area faces the problem of upward movement, and cannot fit tightly on the roller support structure below, thereby increasing the risk of the conveyor belt deviating from the center line. In order to prevent the above situation, two pressure wheels are arranged at the lowest point of the conveyor belt climbing area, and the conveyor belt is pressed by the pressure wheels to prevent the part of the conveyor belt in the climbing area from not fitting on the roller support structure below due to upward movement, and to prevent the conveyor belt from contacting the tunnel roof. However, after the pressure wheels are arranged on the conveyor belt, the coal at the edge of the conveyor belt will hit the pressure wheels during the conveyor belt transportation process, causing the pressure wheels to be worn and affecting the service life of the pressure wheels. At the same time, the coal will fall from the conveyor belt after being blocked by the pressure wheels, and the workload of cleaning the fallen coal needs to be increased. Summary of the invention

[0008] Specifically, a supporting wheel in contact with the pressing wheel is provided on the upper side of the pressing wheel, the supporting wheel is arranged parallel to the pressing wheel, a U-shaped frame is sleeved on the supporting wheel, the supporting wheel is rotatably installed in the U-shaped frame through a rotating shaft, a hanging plate is connected and fixed to the side of the U-shaped frame facing the connecting seat, and the end of the hanging plate away from the U-shaped frame is connected and fixed to the connecting seat.

[0009] Specifically, a plurality of small holes are evenly formed on the upper surface of the top seat away from the connecting seat, a plurality of threaded holes aligned with the small holes are evenly formed on the upper surface of the vertical plate, connecting screws are inserted into the small holes, and the lower ends of the connecting screws are threadedly connected in the threaded holes.

[0010] Specifically, a plurality of L-shaped plates are arranged equidistantly from top to bottom on the opposite sides of the two guide plates, an end of the L-shaped plate close to the guide plate is connected and fixed with an extension plate, the extension plate is in contact with the guide plate, and the end of the L-shaped plate away from the extension plate is connected and fixed to the vertical plate.

[0011] Specifically, inclined bosses are provided on both sides of the inclined hole, and the side of the boss away from the vertical plate is perpendicular to the central axis of the stud. The boss is connected and fixed to the vertical plate. The nut is arranged on the side of the boss away from the vertical plate. A through hole aligned with the inclined hole is opened in the middle of one side of the boss, and the stud passes through the channel formed by the through hole and the inclined hole.

[0012] Specifically, two symmetrically arranged support plates are connected and fixed to the lower end of the vertical plate, and a plurality of through holes for inserting U-shaped screws are evenly arranged on one side of the support plate. The support plate and the vertical plate are arranged perpendicular to each other and are an integrally formed structure.

[0013] Specifically, the guide plate and the inclined plate are an integrally formed structure, the inclined plate and the shielding plate are an integrally formed structure, and the lower ends of the shielding plate, the inclined plate and the guide plate are all processed with arc surfaces.

[0014] Beneficial effects of the present invention:

[0015] 1. Adjust the position of the stud along the inclined hole. At this time, the relative position of the pressure wheel and the conveyor belt changes. When the pressure wheel moves to the required position of the conveyor belt, use two nuts to limit the relative position of the stud and the vertical plate to adjust the relative position of the pressure wheel and the conveyor belt as needed. Under the pressure of the two pressure wheels, the part of the conveyor belt in the climbing area is fitted with the roller support structure below to prevent the conveyor belt from moving upward in the climbing area and contacting the top of the lane. The studs are arranged along the direction of the inclined hole to facilitate the annular side of the pressure wheel to be pressed on the inclined edge of the conveyor belt.

[0016] 2. Inclined bosses are provided on both sides of the inclined hole, and the studs are passed through the bosses, so that when the nut is screwed, one side of the nut can be completely fitted with the side of the boss, thereby improving the stability of the nut installation.

[0017] 3. Insert the plug plate on the connecting seat into the slot on the top seat, and use the positioning screw to limit the relative position of the plug plate and the top seat. Adjust the relative position of the shielding plate and the pressure wheel according to the relative position of the pressure wheel and the conveyor belt. At the same time, the connecting seat, plug plate, connecting seat and other components work together to connect the vertical plate and the shielding plate, thereby limiting the relative position of the shielding plate and the conveyor belt.

[0018] 4. A support wheel is installed at the bottom of the connecting seat to contact the pressure wheel, and the support wheel is directly above the pressure wheel. When the pressure wheel rotates driven by the conveyor belt, the pressure wheel drives the support wheel to rotate. At this time, the support wheel, U-shaped frame, connecting seat, top seat and vertical plate can hold the pressure wheel, so that there are support points at both ends of the stud, which prevents the force of the conveyor belt moving upward in the climbing area from acting completely on the connection between the stud and the vertical plate, which is conducive to reducing the strength requirements of the stud and preventing the stud from bending and deforming due to uneven force.

[0019] 5. After the relative positions of the pressure wheel, the baffle plate and the conveyor belt are restricted, the two guide plates are respectively located at the two edges of the upper surface of the conveyor belt. Under the guidance of the two guide plates, the two inclined plates and the two baffle plates, the coal transported on the conveyor belt can pass through the pressure wheel installation area smoothly, and the coal does not contact the pressure wheel, thereby protecting the pressure wheel and preventing the coal from falling in the area where the pressure wheel is arranged on the conveyor belt. Because the distance between the two baffle plates is smaller than the width of the upper surface of the conveyor belt, the two baffle plates gather the coal at the edge of the conveyor belt to the middle area of ​​the upper surface of the conveyor belt, thereby preventing the coal at the edge of the conveyor belt from falling due to the change of the state of the conveyor belt during the climbing process of the conveyor belt.

[0020] 6. Install multiple L-shaped plates on the vertical plate, and make the extension plate installed at one end of the L-shaped plate contact the guide plate. The extension plate increases the contact range between the L-shaped plate and the guide plate. At this time, the structure formed by the L-shaped plate, the extension plate and the vertical plate jointly supports the guide plate, so that the structure formed by the guide plate, the inclined plate and the shielding plate has two-point support, which improves the stability of the structure and prevents the guide plate from moving to the outside of the conveyor belt under the squeezing of coal on the conveyor belt.
