Description

Technical Field

[0001] The invention relates to mechanical manufacturing, and in particular to a novel damping device for a supporting down-conveying belt conveyor after rapid excavation. Background Art

[0002] Belt conveyors, one of the most important conveying equipment for bulk material transportation, offer advantages such as long-distance, high efficiency, large transport capacity, and continuous conveying. When used in conjunction with tunneling machinery for roadway excavation, they enable continuous transport and slag removal, improving roadway efficiency. Underground construction conditions are complex and changeable, and downdrafting is often encountered. Belt conveyors are more susceptible to accidents such as slippage, material spillage, and runaway if the downdraft angle is large, posing numerous risks to project safety.

[0003] To improve the reliability of down-conveyor belt conveyors, damping devices can be added to the load-bearing section to reduce the belt speed and prevent slippage or overspeeding. Common damping devices include damping rollers, damping plates, and damping rubber.

[0004] Among them, the traditional damping plate structure is as follows Figure 1-Figure 2 As shown, it includes an adjustment seat 100, a mounting frame 200, a damping plate 300, a connecting plate 400, and an adjustment bolt 500. Traditional damping plate structures are often used for conventional belt conveyor downhaul operations. They are fastened to the channel steel longitudinal beams via multiple sets of bolts, resulting in a heavy overall weight and complicated installation. However, continuous belt conveyors used for rapid tunneling generally have smaller transport volumes. The longitudinal beams are often made of steel pipes, which have a weak load-bearing capacity. As the tunneling operation gradually extends, the fuselage section must be easily disassembled and assembled, and the upper roller frame is mounted using a hanging mechanism. Therefore, traditional damping plate structures are not suitable for continuous belt conveyors used for rapid tunneling. Furthermore, traditional damping plate structures use a central hook and adjustment nut to adjust the deflection and damping plate angle. The adjustment components are located on the underside of the belt, making operation very inconvenient.

[0005] It can be seen that how to improve the reliability of the damping device is a problem that needs to be solved in this field. Summary of the Invention

[0006] In response to the technical problem of low reliability of the damping device on the existing belt conveyor, the purpose of this solution is to provide a new damping device for the belt conveyor after rapid excavation. By adopting three sets of damping plates, the contact surface is larger and the damping effect is better, which greatly improves the reliability of the damping device and overcomes the problems existing in the existing technology.

[0007] In order to achieve the above-mentioned purpose, the present invention provides a new damping device for a belt conveyor with a rapid excavation and a lower conveyor, wherein the new damping device is suspended on the steel pipe longitudinal beams on both sides of the conveyor; the new damping device includes a bracket, a damping assembly, an adjustment block, a first drive assembly and a second drive assembly; the damping assembly is hinged by a plurality of damping plates; the adjustment block is arranged on the bracket; the two sides of the damping assembly are damping side plates and are hinged to the adjustment block; the first drive assembly is connected to the damping side plates, and drives the damping assembly to move laterally by supporting the side of the adjustment block, thereby driving the damping assembly to adjust the angle to achieve the angle adjustment of the damping device; the second drive assembly is arranged at the bottom of the adjustment block, drives the adjustment block to move vertically, and supports the damping assembly to move upward to achieve the height adjustment of the damping device.

[0008] Furthermore, the novel damping device is hung on the steel pipe longitudinal beams on both sides of the conveyor by arranging U-bolts.

[0009] Furthermore, a bending structure of about half a pound is provided at the edge of each damping plate in the damping assembly.

[0010] Furthermore, a steel plate is provided at the lower portion of the bracket and is cooperatively connected with the second drive assembly.

[0011] Furthermore, a long hole is provided at the bottom of the adjustment block, and is connected to the steel plate on the bracket side through a second driving component.

[0012] Furthermore, the second driving component is a second adjusting bolt, which connects the long hole at the bottom of the adjusting block with the steel plate on the bracket side; by rotating the second adjusting bolt, the adjusting block can be supported and moved upward.

[0013] Furthermore, first threaded holes are provided on the end plates on both sides of the damping assembly for installing the first driving assembly.

[0014] Furthermore, the first driving component is a first adjusting bolt; the first adjusting bolt is arranged in the first threaded hole, and the damping side plate can be driven to move laterally by rotating the first adjusting bolt to adjust the damping inclination angle.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0031] In response to the technical problem of low reliability of the damping device on the existing belt conveyor, the purpose of this solution is to provide a new damping device for the belt conveyor after rapid excavation. By adopting three sets of damping plates, the contact surface is larger and the damping effect is better.

[0032] At the same time, height and angle adjustment devices are arranged on both sides of the damping plate, which can adjust the angle or height of the damping plate, greatly improving the reliability of the damping device.

[0033] The novel damping device provided by this solution includes a bracket 10, a damping assembly and an adjustment assembly; wherein the damping assembly and the adjustment assembly are symmetrically arranged on both sides of the bracket 10, and the adjustment assembly is arranged on both sides of the damping assembly, and the height and angle of the damping plate are adjusted by the adjustment assembly; for the specific structure, see Figure 3-Figure 6 .

[0034] See also Figure 7 The bracket 10 is the mounting body for the damping assembly and the adjusting assembly, and steel plates are provided on both sides of the lower part for matching and connecting with the adjusting assembly.

[0035] Furthermore, the damping assembly includes three damping plates, namely a first damping plate, a second damping plate and a third damping plate; wherein, see Figure 8 , the first damping plate and the third damping plate are damping side plates 8, see Figure 9 The second damping plate is the damping middle plate 9 , and the damping side plates 8 are arranged on both sides of the damping middle plate 9 .

[0036] The first damping plate, the second damping plate and the third damping plate are hinged and can rotate relative to each other.

[0037] In this solution, the first damping plate, the second damping plate and the third damping plate are hinged together and arranged at the bottom of the material conveyor belt, in direct contact with the conveyor belt 11, thereby increasing the transportation friction of the conveyor belt 11.

[0038] It should be noted here that the damping plate adopts a wear-resistant lining, which can extend the service life of the damping plate; the edge of the damping plate has a large radius bending transition, and the edge of the damping plate bends in the opposite direction of the conveyor belt 11, which can prevent the belt surface from being scratched and provide good protection for the conveyor belt; secondly, the hinged connection method between the first damping plate, the second damping plate and the third damping plate is not limited, and hinges or pins can be used.

[0039] At the same time, long holes are opened in the end ribs of the first damping plate and the third damping plate on both sides, and are movably connected to the adjustment block 12 through the first pin shaft 19 and the second pin shaft 20 respectively. The damping side plate can rotate relative to the adjustment block 12 and can also move horizontally along the long hole.

[0040] The pin shaft type is a B-type pin shaft with a hole, and the first pin shaft 19 and the second pin shaft 20 are fixed with the corresponding type of third flat washer 20, the fourth flat washer 23 and the first cotter pin 21 and the second cotter pin 24, which is convenient for disassembly and assembly.

[0041] Threaded holes are provided on the end plates of the first damping plate and the third damping plate on both sides for placing the first adjusting bolt 1. The damping side plate 8 is driven to move by rotating the first adjusting bolt 1 to support the adjusting block 12, thereby driving the damping side plate 8 to adjust the angle relative to the damping middle plate 9.

[0042] A first locking nut 2 is provided on the first adjusting bolt 1. After the first adjusting bolt 1 adjusts the angle of the damping plate, a first locking nut 2 is used to lock with the threaded hole of the end plate of the damping side plate 8, and a double nut structure is used to lock to fix the inclination angle of the damping plate.

[0043] The first adjusting bolt 1 and the first locking nut 2 cooperate to form a first driving assembly and cooperate with the damping side plate 8 and the adjusting block 12 to form a damping plate angle adjustment mechanism. When in use, first loosen the first locking nut 2, rotate the first adjusting bolt 1 to move axially, and press the adjusting block 12 to drive the damping side plate 8 to move, thereby driving the damping side plate 8 to adjust the angle relative to the damping middle plate 9, changing the angle between the damping plates, and then perform double nut locking through the threaded holes of the first locking nut 2 and the end plate of the damping side plate 8 to fix the angle of the damping plate, thereby adjusting the damping inclination angle.

[0044] See also Figure 10 A circular hole is opened on the top side of the adjustment block 12, which cooperates with the damping side plate 8 through a pin shaft; a long hole is opened at the bottom of the adjustment block 12 to reserve the adjustment length, and the steel plates on both sides of the bracket 10 are connected and fastened by fastening bolts 13, second locking nuts 14, first flat washers 15, and first spring washers 16; a steel plate is welded at the bottom of the adjustment block 12, which is adjusted and used by the second adjusting bolts 17, third locking nuts 18 and the threaded holes of the adjustment plates at the bottom of the steel plates on both sides of the bracket 10.

[0045] During adjustment, the adjustment block 12 is driven to move upward by rotating the second adjustment bolt 17, and the adjustment block 12 drives the damping side plate 8 to move upward through the pin shaft. Conversely, the adjustment block 12 moves downward, and the height of the damping side plate 8 can be lowered; finally, the second locking nut 14, the first flat washer 15, and the first spring washer 16 are connected and tightened by the fastening bolt 13. At the same time, the second adjustment bolt 17 cooperates with the third locking nut 18 and the threaded holes of the adjustment plate at the lower part of the steel plate on both sides of the bracket 10 to perform double-nut structure locking.

[0046] The second adjusting bolt 17 and the third locking nut 18 cooperate to form a second driving assembly and cooperate with the fastening bolt 13 and the second locking nut 14 to form a damping plate height adjustment mechanism. When in use, loosen the second locking nut 14 to make the fastening bolt 13 in a relaxed state; then loosen the third locking nut 18, rotate the second adjusting bolt 17 to move upward, and drive the adjustment block 12 to move upward against the damping side plate 8 to achieve height adjustment of the damping assembly.

[0047] The damping device, which consists of a bracket 10, a damping assembly and an adjusting assembly, is installed and fastened on both sides with the steel pipe longitudinal beam 7 of the conveyor by using U-bolts 3, a fourth locking nut 4, a second flat washer 5, and a second spring washer 6. The hanging installation meets the installation requirements of the rapid excavation continuous belt conveyor. And unlike the hanging method of the load-bearing roller frame, no additional processing and drilling are required on the steel pipe longitudinal beam 7, making installation more convenient.

[0048] The following example illustrates the working process of this solution when in use; it should be noted that the following content is only a specific application example of this solution and does not constitute a limitation on this solution.

[0049] The damping device is installed and fastened to the steel pipe longitudinal beam 7 of the conveyor through U-bolts 4.

[0050] First, the second adjusting bolt 17 is rotated to drive the adjusting block 12 to press against the first damping plate or the third damping plate and move upward to adjust to a suitable position, so that the damping assembly can be fitted to the conveyor belt 11 .

[0051] Then tighten it with the fastening bolts 13 on both sides of the adjustment block 12, and at the same time, use the second adjustment bolt 17 to cooperate with the third locking nut 18 and the threaded holes of the lower adjustment plate of the steel plate on both sides of the bracket 10 to perform double nut structure locking, thereby fixing the height of the damping device.

[0052] Then, by rotating the first adjusting bolts 1 on both sides of the first damping plate and the third damping plate to move axially, the adjustment block is pressed to drive the first damping plate or the third damping plate to adjust the angle, and the double nut structure is locked by cooperating with the threaded hole of the end plate of the damping side plate 8 through the first locking nut 2, thereby fixing the angle of the damping side plate of the damping device.

[0053] The novel damping device for the belt conveyor used for rapid excavation, constructed by the above scheme, increases the friction of the conveyor belt by adding a damping device to the conveyor's load-bearing section. The number of damping devices can be increased according to actual site conditions to reduce the belt speed, thereby effectively solving problems such as slipping and speeding that are prone to occur during the downhaul process. Compared with the existing technology, it has the following advantages:

[0054] The new damping device in this solution can adjust the height of the damping device by adjusting the bolts at the bottom of the adjustment block; at the same time, the damping side plate can be adjusted by adjusting the bolts to change the inclination angle of the side plate, which is convenient for adjustment and adapts to the conveyor belt transportation conditions.

[0055] Secondly, the height and inclination adjustments of the new damping device are located on both sides of the damping device, with a simple structure and easy adjustment.

[0056] In addition, the steel pipe longitudinal beam of the continuous belt conveyor is equipped with U-bolt hanging installation to cooperate with rapid excavation. The installation is convenient and quick, and the overall weight is light.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments.
