[0002] In the related art, when a bridge-type scraper conveyor is operating, the main shaft of the bridge-type scraper conveyor needs to be connected to a driving device so that the driving device drives the main shaft to rotate; among them, the driving device is composed of a motor connected to a reduction device.

[0003] Due to the limitation of the working conditions of the bridge-type scraper conveyor, the width of the position in front of the bridge-type scraper conveyor where the driving device can be placed is relatively narrow, so that the transmission components in the reduction device can only be arranged vertically. When the transmission components in the reduction device are arranged vertically, the distance between the transmission components at the top of the reduction device and the lubricating oil at the bottom of the reduction device is relatively large, so that even if the lubricating oil splashes, it cannot reach the position of the transmission components, resulting in the transmission components not being lubricated. Therefore, after the transmission components operate for a long time, they will be damaged, which in turn affects the quality of the product. Summary of the Invention

[0016] A conveying drive device of a bridge-type scraper conveyor according to the present invention, compared with the prior art, has the beneficial effects as follows:

[0017] 1. Since the first intermediate shaft is located on one side of the input shaft, the second intermediate shaft is located on one side of the first intermediate shaft, the third intermediate shaft is located on one side of the second intermediate shaft, and the output shaft is located on the third intermediate shaft, so that the input shaft, the first intermediate shaft, the second intermediate shaft, the third intermediate shaft and the output shaft are horizontally placed in a plane, making the distances between the center lines of the parts of the input shaft, the first intermediate shaft, the second intermediate shaft, the third intermediate shaft and the output shaft and the bottom surface of the box body the same. Thus, when the first intermediate shaft, the second intermediate shaft, the third intermediate shaft and the output shaft drive the first gear, the second gear, the third gear and the fourth gear to rotate respectively, the first gear, the second gear, the third gear and the fourth gear can splash the lubricating oil poured into the bottom of the box body upward, and then lubricate each component in the box body. Compared with vertically setting the transmission components of the box body, it avoids the situation that the transmission components located in the upper part of the box body are too far away from the lubricating oil at the bottom of the box body, resulting in the lubricating oil not being able to lubricate this transmission component, and avoids the damage of the transmission components, so as to improve the quality of the product. Moreover, since the input shaft, the first intermediate shaft, the second intermediate shaft, the third intermediate shaft and the output shaft are horizontally placed in a plane, the space occupied by the box body in the horizontal direction will increase. Therefore, the main shaft is embedded in the output shaft to realize the hoisting of the box body and the base by the cooperation of the main shaft and the hanger assembly, which improves the stability of the product and at the same time meets the need for lubricating each component in the box body.

[0018] 2. The rotating shaft of the motor is connected to the input shaft through a fluid coupling to avoid the direct connection between the rotating shaft of the motor and the input shaft, thus avoiding the situation that the motor is directly rigidly connected to the input shaft and causing damage to the input shaft, so as to improve the quality of the product.

[0019] 3. By fixing the protective cover on the base and winding the protective cover around the outside of the fluid coupling, the protective cover can protect the fluid coupling, thus avoiding damage to the fluid coupling and improving the quality of the product.

[0020] 4. By sleeving two bearings on the outside of the input shaft and installing the two bearings in the box body, the box body can support the input shaft through the two bearings, thereby improving the flexibility of the input shaft rotation.

[0021] 5. The gaps between the input shaft and the spacer block and the bearing cover are sealed by the first sealing ring and the skeleton oil seal respectively. At the same time, the gap between the input shaft and the box body is sealed by the second sealing ring to realize the combined sealing of the lubricating oil, thus avoiding the outflow of the lubricating oil and improving the quality of the product.

[0022] 6. By making the boom capstan seat rotatably connected to the boom beam, and making the boom body rotatably connected to the base through the lower capstan seat, it is possible to adjust the relative position of the boom beam and the boom body, and to adjust the relative position of the boom body, the base and the box body, so as to facilitate the embedding of the main shaft into the output shaft in the box body, thereby reducing the difficulty of product installation and improving the installation efficiency of the product.

[0023] 7. By setting the first opening at the top of the suspension rod capstan, the upper capstan is embedded in the first opening, and the first pin is passed through the suspension rod capstan and the upper capstan in sequence to achieve a rotational connection between the suspension rod capstan and the upper capstan.

[0024] 8. By setting the second opening at the bottom of the lower capstan seat, the base is embedded in the second opening, and the second pin shaft passes through the lower capstan seat and the base in sequence, so as to realize the rotational connection between the base and the lower capstan seat.

[0025] 9. The two ends of the connecting rod are connected to the two boom bodies respectively to connect the two boom bodies together, so that the two boom bodies and the connecting rod form a stable frame structure to improve the stability of the product.

[0026] 10. By connecting two triangular reinforcing ribs to the side walls of the bridge scraper body and the side walls of the suspension beam at the same time, the connection strength between the side walls of the bridge scraper body and the suspension beam is improved, thereby improving the stability of the box.

[0036] By fixing the box body 15 to the base 14, the box body 15 and the base 14 are connected into a whole, thereby increasing the area of the bottom of the box body 15 that can be connected. By connecting the suspension beam 12 to the side wall of the bridge-type scraper body 10, connecting the top of the hanger assembly 13 to the suspension beam 12, and connecting one end of the base 14 to the bottom of the hanger assembly 13, the suspension beam 12 is hoisted with the base 14 and one side of the box body 15 through the hanger assembly 13.

By embedding the third intermediate shaft 24 into the box body 15 and rotatably connecting the third intermediate shaft 24 with the box body 15, the box body 15 supports the third intermediate shaft 24, so that the third intermediate shaft 24 rotates in the box body 15; by arranging the fifth external teeth 23 on the outer wall of the second intermediate shaft 21, sleeving the third gear 25 on the outside of the third intermediate shaft 24, and meshing the sixth external teeth of the third gear 25 with the fifth external teeth 23, when the second intermediate shaft 21 rotates in the box body 15, the second intermediate shaft 21 drives the third intermediate shaft 24 to rotate through the fifth external teeth 23 and the third gear 25.By passing the output shaft 27 through the box body 15 and rotatably connecting the output shaft 27 with the box body 15, the box body 15 supports the output shaft 27, so that the output shaft 27 can rotate within the box body 15; by arranging the seventh external teeth 26 on the outer wall of the third intermediate shaft 24, sleeving the fourth gear 28 outside the output shaft 27, and meshing the eighth external teeth of the fourth gear 28 with the seventh external teeth 26, when the third intermediate shaft 24 rotates, the third intermediate shaft 24 drives the output shaft 27 to rotate through the seventh external teeth 26 and the fourth gear 28. By setting the output shaft 27 as a hollow cavity with openings at both ends, embedding the main shaft 11 into the output shaft 27, and connecting the main shaft 11 with the output shaft 27, when the output shaft 27 rotates, the output shaft 27 drives the main shaft 11 to rotate, so as to drive the bridge type scraper conveyor body 10 to operate normally; at the same time, since the main shaft 11 is embedded in the output shaft 27, the main shaft 11 supports the output shaft 27 and the box body 15, so as to cooperate with the hanger assembly 13 to hoist the box body 15 and the base 14, thereby improving the stability of the product.

[0037] With the above structure, since the first intermediate shaft 18 is located on one side of the input shaft 16, the second intermediate shaft 21 is located on one side of the first intermediate shaft 18, the third intermediate shaft 24 is located on one side of the second intermediate shaft 21, and the output shaft 27 is located on the third intermediate shaft 24, the input shaft 16, the first intermediate shaft 18, the second intermediate shaft 21, the third intermediate shaft 24 and the output shaft 27 are horizontally placed on a plane, so that the distances between the center lines of the respective parts of the input shaft 16, the first intermediate shaft 18, the second intermediate shaft 21, the third intermediate shaft 24 and the output shaft 27 and the bottom surface of the box body 15 are the same.

Moreover, since the input shaft 16, the first intermediate shaft 18, the second intermediate shaft 21, the third intermediate shaft 24 and the output shaft 27 are horizontally placed on a plane, the space occupied by the box body 15 in the horizontal direction will increase. Therefore, by embedding the main shaft 11 into the output shaft 27, the main shaft 11 and the hanger assembly 13 cooperate to hoist the box body 15 and the base 14, so as to improve the stability of the product. At the same time, it meets the need for lubricating each component within the box body 15.

[0042] With the above structure, the rotating shaft of the motor 29 is connected to the input shaft 16 through the fluid coupling 30, so as to avoid the direct connection between the rotating shaft of the motor 29 and the input shaft 16, thereby avoiding the rigid connection between the motor 29 and the input shaft 16, which may cause damage to the input shaft 16, and improving the quality of the product.
