Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, in particular to a bottom belt deviation adjusting frame of a belt conveyor and a belt conveyor. Background Art

[0002] Belt conveyors are divided into fixed and mobile types, with simple structure and high efficiency. Their structure is an endless conveyor belt wrapped around the driving roller and the driven roller. The upper belt and the bottom belt between the driving roller and the driven roller are supported by several rollers. The upper roller uses three independent rollers, and the bottom roller uses two independent rollers. The friction between the driving roller, the driven roller and the conveyor belt is used to drag the conveyor belt and materials to run. It is suitable for conveying bulk materials and piece items in horizontal and inclined directions, and is widely used in metallurgy, mining, chemical industry, tobacco, printing, food and other industries.

[0003] After long-term operation, belt conveyors can easily deviate from the bottom belt due to factors such as temperature, dust, and uneven friction, preventing them from properly transporting materials. Traditionally, belt deviation adjustment involves raising the bottom roller brackets. This adjustment simultaneously shifts the top belt and results in poor deviation adjustment. Furthermore, the deviated bottom belt is prone to contact with the bottom roller brackets, causing wear. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following is a clear and complete description of the technical solution of the present invention in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are used to illustrate rather than limit the invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] According to the embodiment of the present invention, a bottom belt deflection adjusting frame for a belt conveyor is provided. Figures 1 to 4 , including a connected crossbeam 1 and a support leg 2, both the support leg 2 and the crossbeam 1 are provided with a hanging ear for mounting a bottom roller 5, the hanging ear is inclined in the vertical plane to increase the distance between the bottom belt above the bottom roller 5 and the support leg 2, and the top of the support leg 2 is detachably connected to the frame 10 of the belt conveyor through a connecting assembly.

[0025] It should be noted that the support legs 2 are detachably connected to the conveyor's frame 10. By moving the support legs 2 parallel to the conveyor's conveying direction, the position of the bottom rollers 5 is changed, effectively resolving the problem of the bottom belt's deviation, ensuring the reliable operation of the raw coal transportation system and providing favorable guarantees for safe and efficient production in the mine. Furthermore, the tilted mounting lugs increase the distance between the bottom belt above the bottom rollers 5 and the support legs 2, reducing wear on the bottom belt caused by the support legs 2 and extending the conveyor belt's service life.

[0026] Specifically, under normal conditions, the belt conveyor's belt deflection adjustment bracket is positioned parallel to the conveyor's width. If the left belt deviates during deflection adjustment, the left leg of the belt conveyor's belt deflection adjustment bracket is moved toward the rear of the conveyor. This causes crossbeam 1 to tilt relative to its normal position. The tilt angle is set to ensure the belt is properly aligned.

[0027] In this embodiment of the belt conveyor bottom belt deviation adjustment frame, please refer to Figures 1 to 3 The two ends of the crossbeam 1 are connected to the legs 2, and the two legs 2 and the crossbeam 1 form an H-shaped structure.

[0028] It should be noted that the legs 2 support the beam 1 to improve stability.

[0029] In this embodiment of the belt conveyor bottom belt deviation adjustment frame, please refer to Figures 1 to 3 The hanging ear includes a first hanging ear 3 connected to the beam 1. The first hanging ear 3 is set to a plate structure, one end of which is connected to the beam 1, and the other end of which is provided with a first mounting groove.

[0030] It should be noted that the first mounting groove is used to mount the roller shaft of the bottom supporting roller 5 , and the roller shaft is rotatably connected to the bottom supporting roller 5 .

[0031] In this embodiment of the belt conveyor bottom belt deviation adjustment frame, please refer to Figures 1 to 3 The lugs include a second lug 4 connected to the leg 2. The second lug 4 is configured as a bent structure. The bent structure includes a fixed end 401 connected to the leg 2 and a free end 402 having a second mounting groove. The free end 402 is arranged at an angle. Similarly, the second mounting groove is used to mount the roller shaft of the bottom roller 5.

[0032] It should be noted that the two bottom rollers 5 have a V-shaped structure, and accordingly, the first hanging ear 3 is located lower than the second hanging ear 4. At the same time, to avoid structural interference, the free ends 402 of the first hanging ear 3 and the second hanging ear are parallel, that is, the inclination angle and inclination direction of the two are the same.

[0033] In this embodiment of the belt conveyor bottom belt deviation adjustment frame, please refer to Figures 1 to 4 The connection assembly includes a connection base plate 6, a connection cover plate 7, and a connection member 9. The connection base plate 6 is connected to the top of the support leg 2. The connection base plate 6 and the connection cover plate 7 are spaced apart to form a space for accommodating the frame 10 of the belt conveyor. The connection member 9 is used to connect the connection base plate 6 and the connection cover plate 7. At the same time, a plurality of through holes are correspondingly provided on the connection base plate 6 and the connection cover plate 7, and the connection member 9 is located in the through holes.

[0034] It should be noted that two 200mm x 200mm square plates are machined from 10mm thick iron plates to serve as the connecting base plate 6 and the connecting cover plate 7, respectively. Four through-holes are machined in each square plate according to the cross-sectional dimensions of the frame 10. The legs 2 are secured to the frame 10 using the square plates and M16 U-bolts (connectors), ensuring full contact between the bottom rollers 5 and the bottom belt. It is worth noting that, compared to the cross-sectional dimensions of the frame 10, the cross-sectional dimensions of the square plates allow for adjustment, allowing for a 15° tilt of the crossbeam 1 compared to its normal state.

[0035] In addition, anti-slip grooves can be provided on the surfaces opposite to the connecting bottom plate 6 and the connecting cover plate 7 to improve the relative stability of the legs 2 and the frame 10. The through holes can also be provided as elongated holes to accommodate frames 10 of different cross-sectional sizes.

[0036] In this embodiment of the belt conveyor bottom belt deviation adjustment frame, please refer to Figures 1 to 3 A support base 8 is provided below the support leg 2 to increase the contact area with the ground and improve stability.

[0037] According to an embodiment of the present invention, a belt conveyor is provided. Figures 1 to 4 , including a frame 10, and a plurality of the belt conveyor bottom belt adjustment frames are arranged at intervals along the extension direction of the frame 10.

[0038] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
