Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine machinery and equipment, and in particular relates to a self-moving tail lifting device for belt conveyors. Background Technology

[0002] Self-propelled belt conveyor tail sections are used for the rapid movement and proper overlap of the transfer conveyor and belt conveyor tail sections in high-yield and high-efficiency working faces, meeting the needs of high-speed and rapid advancement of the working face. However, with the increasing intelligence of coal mine fully mechanized mining equipment, the existing moving stroke can no longer meet the needs of efficient coal production. Therefore, extending the moving stroke of self-propelled belt conveyor tail sections has become an urgent need in coal production. However, with the extension of the moving stroke, the overall structure of the self-propelled tail section is also lengthened, which increases the difficulty of moving during the process and makes it easy for the mechanism to collapse in the middle on uneven ground.

[0003] During underground mining, to reduce the frequent movement of the conveyor belt's self-moving tail section, our company developed a long-stroke self-moving tail section, increasing the transfer conveyor's movement from three cuts per movement to ten cuts per movement, or even more. However, due to the limitations of the self-moving tail section's lifting cylinder, the overall height of the transfer conveyor and self-moving tail section combined is 2.3 meters, requiring the underground roadway height to be no less than 3 meters. Some small coal mines, due to their low roadway height, cannot accommodate this type of equipment. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a lifting device for the self-moving tail of a belt conveyor, which can reduce the overall height of the transfer machine and the self-moving tail after they are matched, thereby adapting to roadways with lower heights and increasing the application scenarios of coal mining equipment.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A lifting device for a self-moving tail section of a belt conveyor is disclosed. The lifting device is applicable to a self-moving tail section of a belt conveyor and includes a frame with guide rails on both sides. The lifting device includes a connecting seat A, a connecting seat B, a power component, a rocker arm, and a connecting rod. One end of connecting seat A and connecting seat B are fixedly mounted on the frame. The other end of connecting seat A is hinged to one end of the power component, and the other end of the power component is hinged to the rocker arm. The other end of connecting seat B is hinged to the rocker arm. One end of the connecting rod is fixedly connected to the guide rail on the corresponding side, and the other end of the connecting rod is hinged to the rocker arm.

[0007] Furthermore, the height of the connecting seat B is higher than the height of the connecting seat A.

[0008] Furthermore, the power component is a jack.

[0009] Furthermore, the fixed end of the jack is hinged to the connecting seat A, and the telescopic end of the jack is hinged to the rocker arm.

[0010] Furthermore, multiple lifting devices are provided, and the multiple lifting devices are arranged at intervals.

[0011] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

The self-moving tail section lifting device 3 for a belt conveyor of this embodiment is applicable to a self-moving tail section of a belt conveyor, which includes a frame 1, and guide rails 2 are provided on both sides of the frame 1.

[0020] The self-moving tail lifting device 3 for the belt conveyor includes a connecting seat A 32, a connecting seat B 34, a power component, a rocker arm 33, and a connecting rod 35. One end of the connecting seat A 32 and the connecting seat B 34 are fixedly mounted on the frame 1. The other end of the connecting seat A 32 is hinged to one end of the power component, and the other end of the power component is hinged to the rocker arm 33. The other end of the connecting seat B 34 is hinged to the rocker arm 33. One end of the connecting rod 35 is fixedly connected to the guide rail 2 on the corresponding side, and the other end of the connecting rod 35 is hinged to the rocker arm 33.

[0021] Preferably, the height of connector B 34 is higher than the height of connector A 32.

[0022] Preferably, the power component is a jack 31, or other power components that can provide extension and retraction power can also be selected.

[0023] More preferably, the jack 31 is arranged horizontally. Compared with the vertical arrangement of the power components in the prior art, the lifting device 3 for the self-moving tail of the belt conveyor of this utility model can reduce the overall height of the transfer machine and the self-moving tail of the belt conveyor, thereby adapting to roadways with lower heights and increasing the application scenarios of coal mining equipment.

[0024] Preferably, the fixed end of the jack 31 is hinged to the connecting seat A 32, and the telescopic end of the jack 31 is hinged to the rocker arm 33.

[0025] Preferably, multiple self-moving tail-end lifting devices 3 for belt conveyors are provided, and these multiple self-moving tail-end lifting devices 3 are arranged at intervals. The use of multiple tail-end lifting devices for belt conveyors can ensure the smooth self-moving of the self-moving tail of the belt conveyor.

[0026] The self-moving process of the self-moving tail of the belt conveyor using the self-moving tail lifting device 3 of this utility model is described in detail below:

[0027] Combination Figure 2 As shown, in the initial state, the jack 31 is in a semi-extended state, the guide rail 2 rests on the base plate, and the internal pressure of the jack 31 is 0.

[0028] Combination Figure 3 As shown, when the self-moving tail section of the belt conveyor moves forward, the frame 1 is lifted and raised by 200mm. In this state, the jack 31 is fully extended, and the rocker arm 33 drives the connecting rod 35 to move. The reaction force of the guide rail 2 on the connecting rod 35 lifts the frame 1. Subsequently, the pushing action of the push cylinder causes the self-moving tail section of the belt conveyor to move forward.

[0029] Combination Figure 4 As shown, after the frame 1 completes its forward movement, the guide rail 2 needs to be retracted. At this time, the guide rail 2 is raised by 100mm. In this state, the jack 31 is fully retracted, and the rocker arm 33 drives the connecting rod 35 to move. The connecting rod 35 is connected to the guide rail 2, raising the guide rail 2 100mm above the ground. Subsequently, the guide rail 2 is pulled forward by the pulling action of the push cylinder.
