A tail adjusting assembly of a belt conveyor in a tunneling working face

Abstract

This utility model relates to the field of belt conveyor technology and discloses a tail adjustment component for a belt conveyor in a tunneling face. The tail adjustment component includes: a bracket; a support frame is fixedly installed above the bracket; crossbeams are fixedly installed at both ends of the support frame; a connecting block is fixedly installed on one side of the crossbeams; a transition block is movably installed inside the connecting block; and a transmission piston is fixedly installed at the bottom end of the transition block. During the movement of the bracket after it is suspended in the air, gravel will enter the groove structure of the bracket under the guidance of the groove structure. Because the groove structure of the bracket increases the distance between the bracket and the bottom surface, the top of the gravel does not contact the top surface of the groove structure after entering it, thus preventing the gravel from getting stuck at the bottom of the bracket and causing friction due to the gravel during movement, which would affect the movement trajectory of the bracket.

Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically to a tail adjustment component for a belt conveyor in a tunneling face. Background Technology

[0002] The self-propelled tail section of a belt conveyor is a major transportation device in coal mine tunneling faces. It is installed between the head section of a transfer conveyor and the tail section of a belt conveyor. The head section of the transfer conveyor is connected to the guide rail of the self-propelled tail section. Coal is unloaded from the head section of the transfer conveyor onto the self-propelled tail section and then transferred to the belt conveyor for transport to the surface.

[0003] The existing Chinese utility model patent with publication number CN221543029U discloses a self-moving tail section for a belt conveyor, including a conveyor body, an inclined component on one side of the conveyor body, a transport component on one side of the inclined component, and a power component on one side of the transport component. This application, by incorporating the inclined component, transport component, and power component, allows for the adjustment of the tail section's tilt angle by activating a first hydraulic rod during operation, thus improving practicality. Activating the power motor rotates a connecting rod, which in turn rotates a third bevel gear, a second bevel gear, and a first bevel gear, which in turn rotates a bidirectional screw. This causes two first sliding blocks on the bidirectional screw to slide in opposite directions, tilting the transport rollers. This facilitates changing the tilt angle of the tail section for loading goods and allows for adjustment of the transport rollers' tilt angle to transport loads of different sizes.

[0004] The existing tail adjustment assembly supports the piston via rollers mounted above the sleeper rail. The rollers and sleeper rail wear down with use, and the sleeper rail requires a sliding connection with the support piston. Replacing the rollers is complex and difficult to maintain. Furthermore, the existing tail adjustment assembly has a small distance between the bottom plane of the bracket and the ground when moving the bracket, allowing ground debris to get stuck underneath. This results in greater friction on one side of the bracket than the other, causing the tail section to deflect during movement. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a tail adjustment component for a belt conveyor in a tunneling face, which has advantages such as preventing gravel from getting stuck under the bracket and facilitating the replacement of rollers, thus solving the aforementioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a tail adjustment assembly for a belt conveyor in a tunneling face, comprising: a bracket, a support frame fixedly installed above the bracket, crossbeams fixedly installed at both ends of the support frame, a connecting block fixedly installed on one side of the crossbeam, a transition block movably installed inside the connecting block, a transmission piston fixedly installed at the bottom end of the transition block, a fixing block movably installed at the bottom end of the transmission piston, a fixing bolt inserted into one side of the fixing block, a sleeper rail fixedly installed inside the fixing block, a fixing ring fixedly installed on one side of the crossbeam, a support piston fixedly installed at the center of the fixing ring, a connecting plate fixedly installed at the bottom end of the support piston, a connecting column inserted into the connecting plate, clamping plates inserted into both sides of the connecting column, rollers movably installed between the clamping plates, limit plates inserted into both ends of the connecting column, and connecting bolts movably installed at both ends of the connecting column; the bracket can support the support frame.

[0009] As a preferred embodiment of this utility model, the bracket is symmetrically installed on the left and right sides with the center of the crossbeam as the reference, the support roller and the support frame are rotatably connected, and the support frame is installed at equal intervals on the left and right sides; the support roller can support the conveyor belt.

[0010] As a preferred technical solution of this utility model, the crossbeam is symmetrically installed on the front and rear sides of the support frame with the center of the support frame as the reference. The transition block is fixedly installed on the upper and lower ends of the transmission piston. The transition block, the connecting block, and the fixing block form a rotatable connection. The fixing block can facilitate the fixed connection between the bottom end of the transmission piston and the sleeper rail.

[0011] As a preferred embodiment of this utility model, the fixing block is installed symmetrically on the front and rear sides of the sleeper rail by fixing bolts and is fixedly connected to the sleeper rail. The supporting piston is fixedly connected to the crossbeam by a fixing ring. The sleeper rail can restrict the movement direction of the roller.

[0012] As a preferred embodiment of this utility model, the movable end of the supporting piston points towards the sleeper rail, and the connecting column forms a sliding connection with the connecting plate, the clamping plate, and the limiting plate; the connecting column can limit the position between the connecting plate, the clamping plate, and the limiting plate.

[0013] As a preferred embodiment of this utility model, the rollers are symmetrically installed between the clamping plates and are rotatably connected to the clamping plates. The bottom of the rollers contacts the sleeper rail, and the front and rear sides of the sleeper rail are provided with strip-shaped protrusions. The clamping plates can restrict the position of the rollers.

[0014] As a preferred technical solution of this utility model, the bottom end of the limiting plate is provided with a corner that fits into the protruding structure of the sleeper rail, and the limiting plate and the sleeper rail form a sliding connection. The diameter of the disc structure at the head of the connecting bolt is larger than the diameter of the connecting column. The connecting bolt can make the two side clamping plates and the limiting plate clamp the connecting plate.

[0015] Compared with the prior art, this utility model provides a tail adjustment component for a belt conveyor in a tunneling face, which has the following advantages:

[0016] 1. This utility model features a bracket with equidistant grooves on its bottom surface. The grooves are funnel-shaped at both ends. As the bracket moves while suspended, gravel is guided into the grooves by the bracket. Because the grooves increase the distance between the bracket and the bottom surface, the top of the gravel does not contact the top surface of the groove after entering the groove. This prevents the gravel from getting stuck at the bottom of the bracket, thus avoiding friction caused by the gravel during movement and affecting the bracket's trajectory.

[0017] 2. This utility model, through the setting of the connecting column, forms a sliding connection between the connecting column, the connecting plate, the clamping plate, and the limiting plate. The rollers are symmetrically installed between the clamping plates and form a rotating connection with the clamping plates. The bottom of the rollers contacts the sleeper rail. Connecting bolts are movably installed at the front and rear ends of the connecting column. The diameter of the disc structure at the head of the connecting bolt is larger than the diameter of the connecting column. When the connecting bolt is tightened, the thread structure of the connecting bolt completely enters the interior of the connecting column. The disc structure at the head of the connecting bolt will cause the limiting plate and the clamping plate to clamp the connecting plate, thereby restricting the position of the roller. When replacing, the bottom surface of the bracket touches the ground, and the connecting bolts are removed. The limiting plate and the clamping plate can then be removed from the front and rear sides of the connecting column by sliding, and then the roller can be replaced. Attached Figure Description

[0026] Please see Figure 1 - Figure 4In this embodiment, a tail adjustment assembly for a belt conveyor in a tunneling face includes: a bracket 1; a support frame 11 is fixedly installed above the bracket 1; crossbeams 13 are fixedly installed at both ends of the support frame 11; a connecting block 14 is fixedly installed on one side of the crossbeams 13; a transition block 15 is movably installed inside the connecting block 14; a transmission piston 16 is fixedly installed at the bottom end of the transition block 15; a fixing block 17 is movably installed at the bottom end of the transmission piston 16; a fixing bolt 18 is inserted into one side of the fixing block 17; and the inner side of the fixing block 17... A sleeper rail 19 is fixedly installed. A fixing ring 110 is fixedly installed on one side of the crossbeam 13. A support piston 111 is fixedly installed at the center of the fixing ring 110. A connecting plate 112 is fixedly installed at the bottom of the support piston 111. A connecting column 113 is inserted inside the connecting plate 112. Clamping plates 114 are inserted on both sides of the connecting column 113. Rollers 115 are movably installed between the clamping plates 114. Limiting plates 116 are inserted at both ends of the connecting column 113. Connecting bolts 117 are movably installed at both ends of the connecting column 113.

[0027] The bracket 1 is symmetrically installed left and right with the center of the crossbeam 13 as the reference. The support roller 12 is rotatably connected to the support frame 11. The support frame 11 is installed equidistantly on the left and right sides. The crossbeam 13 is symmetrically installed front and back on both sides of the support frame 11 with the center of the support frame 11 as the reference. The transition block 15 is fixedly installed at the upper and lower ends of the transmission piston 16. The transition block 15 is rotatably connected to the connecting block 14 and the fixing block 17. The fixing block 17 is symmetrically installed front and back on both sides of the sleeper rail 19 by fixing bolts 18 and is fixedly connected to the sleeper rail 19. The support piston 111 is connected to the crossbeam 13 by the fixing ring 110. The fixed connection is provided, with the movable end of the supporting piston 111 pointing towards the sleeper rail 19. The connecting column 113 is slidably connected to the connecting plate 112, the clamping plate 114, and the limiting plate 116. The rollers 115 are symmetrically installed between the clamping plates 114 and are rotatably connected to the clamping plates 114. The bottom of the rollers 115 contacts the sleeper rail 19. The front and rear sides of the sleeper rail 19 are provided with strip-shaped protrusions. The bottom end of the limiting plate 116 is provided with a corner that fits into the protrusions of the sleeper rail 19, and the limiting plate 116 is slidably connected to the sleeper rail 19. The diameter of the disc structure at the head of the connecting bolt 117 is larger than the diameter of the connecting column 113.

[0028] Specifically, the bottom surface of the bracket 1 is provided with a groove structure with equal front and rear spacing, and the front and rear ends of the groove structure are flared to allow crushed stone to enter the groove structure when the bracket 1 moves, preventing the crushed stone from getting stuck at the bottom of the bracket 1. The bracket 1 can support the upper support frame 11 when the sleeper rail 19 is raised. The support roller 12 installed on the upper support frame 11 supports the conveyor belt and limits the stretching of the conveyor belt after bearing the load. The position of the support frame 11 is limited by the crossbeam 13 connecting all the support frames 11. The connecting block 14 and the transition block 15 facilitate the rotational connection between the top of the transmission piston 16 and the crossbeam 13. The bottom of the transmission piston 16 is rotatedly connected to the sleeper rail 19 through the transition block 15 and the fixing block 17, thereby connecting the transmission piston 16 to the crossbeam 13 and the crossbeam 19. The sleeper rail 19 can change its angle to facilitate the movement of the connecting block 14. The sleeper rail 19 can limit the movement direction of the device. The fixing ring 110 can limit the position of the fixed end of the support piston 111. The bottom end of the support piston 111 is fixedly connected to the connecting plate 112. The roller 115 is installed below the connecting plate 112 through the clamping plate 114 and contacts the sleeper rail 19. The support piston 111 lifts the crossbeam 13 to suspend the bottom surface of the bracket 1. The weight of the device will be transmitted to the sleeper rail 19 through the roller 115. Then, the relative position between the crossbeam 13 and the sleeper rail 19 is adjusted by the extension and retraction of the transmission piston 16 to move the device. The limiting plate 116 can limit the relative position between the sleeper rail 19 and the roller 115. When the support piston 111 retracts, it can suspend the sleeper rail 19.

[0029] In use, the bottom surface of the bracket 1 is provided with a groove structure with equal front and rear distances, and the front and rear ends of the groove structure are flared. During the movement of the bracket 1 after it is suspended in the air, the gravel will be guided into the groove structure of the bracket 1 by the groove structure. Because the groove structure of the bracket 1 increases the distance between the bracket 1 and the bottom surface, the top of the gravel does not contact the top surface of the groove structure after it enters the groove structure, thus avoiding the gravel getting stuck at the bottom of the bracket 1. This would prevent the bracket 1 from generating friction due to the gravel during movement, which would affect the movement trajectory of the bracket 1. The connecting column 113 is slidably connected to the connecting plate 112, the clamping plate 114, and the limiting plate 116. The rollers 115 are symmetrically installed between the clamping plates 114 and are connected to the clamping plate 116. The plates 114 are rotatably connected. The roller 115 contacts the rail 19 below. The connecting bolts 117 are movably installed at the front and rear ends of the connecting column 113. The diameter of the disc structure at the head of the connecting bolt 117 is larger than the diameter of the connecting column 113. When the connecting bolt 117 is tightened, the thread structure of the connecting bolt 117 completely enters the interior of the connecting column 113. The disc structure at the head of the connecting bolt 117 will cause the limiting plate 116 and clamping plate 114 to clamp the connecting plate 112, thereby restricting the position of the roller 115. When replacing, the bottom surface of the bracket 1 touches the ground. The connecting bolts 117 can be removed, and the limiting plate 116 and clamping plate 114 can be removed from the front and rear sides of the connecting column 113 by sliding. Then the roller 115 can be replaced.
