Description

Technical Field

[0001] This utility model relates to the field of belt conveyor equipment technology, and in particular to a belt conveyor self-moving tail belt adjustment device. Background Technology

[0002] As a core piece of equipment in continuous underground coal mine transportation systems, the self-aligning tail section of a belt conveyor traditionally relies on a horizontal hydraulic cylinder at the bottom of the sliding shoe to drive the lateral displacement of the conveyor body and achieve dynamic belt alignment. While this technology is well-suited for conventional roadway floor conditions, it exhibits significant limitations in soft, fractured floor environments. When the floor's load-bearing capacity is insufficient, the horizontal cylinder's movement causes plastic deformation in the contact area between the sliding shoe and the floor, increasing lateral movement resistance and reducing displacement control accuracy. This directly weakens the lateral alignment of the conveyor belt, preventing raw coal unloading at the transfer machine from accurately landing in the center of the conveyor belt, resulting in some spillage. This spillage not only reduces the efficiency of the transportation system but also significantly increases the workload of workers, requiring additional time for cleanup. Furthermore, prolonged off-center loading exacerbates wear on the conveyor belt and related components, increasing equipment operation and maintenance costs and posing a potential threat to mine safety.

[0006] The two floating cylinders are arranged along the Y direction, and the cylinder body of the floating cylinder is hinged to the tail end frame of the belt conveyor.

[0007] The adjusting frame is located below the floating cylinder. The adjusting frame is hinged to the self-moving tail frame of the belt conveyor. The piston rod of the floating cylinder is hinged to the adjusting frame. The floating cylinder is used to drive the adjusting frame to move reciprocally vertically.

[0008] The idler roller assembly is used to carry the belt, and the idler roller assembly is arranged above the adjustment frame along the Y direction;

[0009] The two lifting cylinders are respectively arranged on both sides of the roller group along the Y direction. The lifting cylinder is vertically arranged and its cylinder body is mounted on the adjustment frame. The piston rod of the lifting cylinder is connected to the end of the roller group. The lifting cylinder is used to drive the end of the roller group to move back and forth vertically.

[0010] Preferably, the adjustment frame includes a mounting plate and two connecting rods respectively fixed at its ends;

[0021] After adopting the above technical solution, the beneficial effects of this utility model are:

[0022] This application includes two floating cylinders, an adjusting frame, a roller assembly, and two lifting cylinders. The two floating cylinders are arranged along the Y direction, and the cylinder body of the floating cylinder is hinged to the tail end frame of the conveyor belt. The width direction of the tail end frame of the conveyor belt is defined as the Y direction, and its length direction is defined as the X direction. The adjusting frame is located below the floating cylinders and is hinged to the tail end frame of the conveyor belt. The piston rod of the floating cylinder is hinged to the adjusting frame. The floating cylinder is used to drive the adjusting frame to move vertically back and forth. Because the adjusting frame is hinged to the tail end frame of the conveyor belt, and the floating cylinder 1 is also hinged to the tail end frame of the conveyor belt, when it is necessary to drive the adjusting frame to move upward, the piston rod of the floating cylinder retracts, which can drive it to move upward.

When the tilt angle of the idler roller assembly needs to be adjusted to achieve left-right belt misalignment, simply extending or retracting the piston rod of one lifting cylinder will move one end of the idler roller assembly up or down, thus achieving left-right belt misalignment. Simultaneously, in conjunction with the floating cylinder, it enables vertical and horizontal adjustment of the belt, ensuring smooth coal unloading from the transfer machine, preventing spillage, reducing worker workload, and lowering maintenance costs.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] like Figures 1 to 3 As shown in the figure, this utility model includes two floating cylinders 1, an adjusting frame 2, a roller group 3 and two lifting cylinders 4. The width direction of the self-moving tail frame 5 of the belt conveyor is defined as the Y direction, and its length direction is defined as the X direction.

[0032] In this configuration, two floating cylinders 1 are arranged along the Y-axis. The cylinder body of the floating cylinder 1 is hinged to the tail end frame 5 of the conveyor belt. Preferably, the adjusting frame 2 is located below the floating cylinder 1 and is hinged to the tail end frame 5 of the conveyor belt. The piston rod of the floating cylinder 1 is hinged to the adjusting frame 2. The floating cylinder 1 is used to drive the adjusting frame 2 to reciprocate vertically. In this application, because the adjusting frame 2 is hinged to the tail end frame 5 of the conveyor belt and the floating cylinder 1 is also hinged to the tail end frame 5 of the conveyor belt, when it is necessary to drive the adjusting frame 2 to move upward, the piston rod of the floating cylinder 1 retracts, which can drive it to move upward. When it is necessary to drive the adjusting frame 2 to move downward, the piston rod of the floating cylinder 1 extends, which can drive it to move downward.

[0033] Preferably, the diameter of the floating cylinder 1 is 125mm and the stroke of the floating cylinder 1 is 250mm; the diameter of the lifting cylinder 4 is 80mm and the stroke of the lifting cylinder 4 is 100mm.

[0034] The idler roller group 3 is used to carry the belt (not shown in the figure). The idler roller group 3 is set above the adjusting frame 2 along the Y direction. Two lifting cylinders 4 are set on both sides of the idler roller group 3 along the Y direction. The lifting cylinder 4 is set vertically and its cylinder body is installed on the adjusting frame 2. The piston rod of the lifting cylinder 4 is connected to the end of the idler roller group 3. The lifting cylinder 4 is used to drive the end of the idler roller group 3 to move back and forth vertically.

[0035] In this application, in order to ensure that the coal on the transfer machine can be smoothly unloaded to the middle position of the belt, the position of the belt needs to be adjusted. Based on this purpose, when it is necessary to adjust the tilt angle of the idler roller group 3 to achieve left and right belt adjustment, it is only necessary to extend or retract the piston rod of the lifting cylinder 4 on one side, which can drive one end of the idler roller group 3 to move up or down, thereby achieving left and right belt adjustment. At the same time, in conjunction with the floating cylinder 1, the belt can be adjusted up, down, left and right, ensuring that the transfer machine can unload coal smoothly, preventing spillage, reducing the labor intensity of workers, and reducing maintenance costs.

[0036] In this application, the adjustment frame 2 includes a mounting plate 21 and two connecting rods 22 respectively fixed at its ends. The ends of the connecting rods 22 are hinged to the tail end frame 5 of the conveyor belt via head frame hinge ears 23. The mounting plate 21 is arranged along the Y direction, and connecting rods 22 are fixed at both ends. The mounting plate 21 is hinged to the tail end frame 5 of the conveyor belt via the two connecting rods 22, which drives the mounting plate 21 to move back and forth vertically.

[0037] The mounting plate 21 is fixed with a floating cylinder hinge ear 24. The piston rod of the floating cylinder 1 is hinged to the floating cylinder hinge ear 24. The hinge can meet the requirement that the floating cylinder 1 drives the mounting plate 21 to move up and down. The floating cylinder hinge ear 24 is located on the outside of the lifting cylinder 4 along the Y direction. It will not interfere with the installation of the lifting cylinder 4, nor will it affect the lifting operation of the lifting cylinder 4.

[0038] An inclined baffle 25 is installed on the hinge lug 24 of the floating cylinder, and the inclined baffle 25 is arranged along the X direction on the side away from the floating cylinder 1. The inclined baffle 25 can improve the mechanical strength of the hinge lug 24 of the floating cylinder and extend its service life.

[0039] In this application, a plurality of supporting ribs 26 are fixedly provided at the bottom of the mounting plate 21, and a plurality of reinforcing ribs 27 are fixedly provided on the connecting rod 22. The provision of supporting ribs 26 and reinforcing ribs 27 can respectively enhance the supporting strength of the mounting plate 21 and the connecting strength of the connecting rod 22.

[0040] The idler assembly 3 includes an idler frame 31 and three idlers 32 mounted on it; both ends of the idler frame 31 are equipped with lifting cylinder connecting ears 33, and the piston rod of the lifting cylinder 4 is connected to the lifting cylinder connecting ears 33.

[0041] This application is installed on the tail section frame 5 of the self-propelled conveyor belt to ensure that coal on the transfer conveyor can be smoothly unloaded to the middle position of the belt. During use, the belt is adjusted according to the coal unloading position of the transfer conveyor, including vertical and horizontal adjustments. Vertical belt adjustment is achieved by extending and retracting the piston rod of the floating cylinder 1, which drives the adjusting frame 2, idler roller group 3, and lifting cylinder 4 to move up and down together. Horizontal belt adjustment is achieved by adjusting one side of the lifting cylinder 4, extending or retracting its piston rod, which moves one end of the idler roller group 3 up or down, thus adjusting the belt's left or right alignment. By coordinating the floating cylinder 1 and the lifting cylinder 4, vertical and horizontal belt adjustments can be achieved, ensuring smooth coal unloading from the transfer conveyor, preventing spillage, reducing worker labor intensity, and lowering maintenance costs.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
