[0002] The retractable belt conveyor is mainly used for transporting raw coal and gangue in the mining working face of coal mines. The general layout is that the head of the machine is used for loading and unloading, and it is basically immobile; the tail of the machine is connected with the transfer machine of the comprehensive mining machine or comprehensive excavation machine at the working face, and needs to move forward and backward with the advancement or retreat of the working face, forming the extension or shortening of the entire conveyor.

[0003] To move the tail forward or backward, you need to stop the conveyor first, and then realize the telescopic function of the entire conveyor through the cooperation between the tensioner, the belt retracting device, the tail and the fuselage (upper roller, lower roller, outrigger and longitudinal beam).

[0004] Since multiple devices are involved and there are many parts in the machine body, disassembly and assembly require multiple people, which is time-consuming and labor-intensive.

[0020] The present invention is described in further detail below.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0022] Combination Figure 1 , Figure 2 As shown, this embodiment provides a device for disassembling and assembling the body of a telescopic belt conveyor without stopping the machine. The arch frame 2 is arranged in front of the self-moving tail 15 of the conveyor, and when the self-moving tail 15 moves, the arch frame 2 is dragged to move synchronously.

[0023] A horizontal slide 4 is fixedly connected to the lower end of the arch frame 2, and a longitudinal beam frame 10 and a second redirecting assembly 11 are slidably connected on a slideway in the middle of the slide 4. Two pairs of slideways are symmetrically arranged on the outer side of the slide 4, and four (two groups of front and rear) mechanical arms 7 are slidably connected to each other.

[0024] The mechanical arm 7 is L-shaped, and the upper end of the mechanical arm 7 is horizontally rotatably connected to the slide 4. The upper end of the mechanical arm 7 in the vertical direction is a telescopic structure for adjusting the height of the mechanical arm 7. The end of the mechanical arm 7 in the horizontal direction is a telescopic structure for adjusting the length of the mechanical arm 7 in the horizontal direction. The end of the mechanical arm 7 in the horizontal direction is detachably connected to the side of the supporting leg 6. The main function of the two groups of mechanical arms 7 is that when disassembling and assembling the fuselage, one group of mechanical arms 7 at the tail fixes the last pair of supporting legs 6 of the original fuselage, and the other group of mechanical arms 7 moves with the arch frame 2, passes the currently fixed mechanical arms 7, and moves to the front of the clamping frame 133 to be re-fixed with the new supporting legs 6. By using the two groups of mechanical arms alternately, they can not only cooperate with the longitudinal beam frame 10 and the support leg clamping assembly 13 for precise positioning, but also prevent the fuselage from being displaced due to the longitudinal tension of the belt when the longitudinal beam and the support leg are clamped. When the conveyor is operating normally, the two groups of mechanical arms 7 clamp the last two pairs of supporting legs 6 at the same time, so that the self-moving tail 15 forms a whole with the fuselage through this device.

[0025] Combination Figure 3As shown, the longitudinal beam frame 10 includes a sliding seat 101 and a longitudinal beam gripper 102. A telescopic rod is provided in the middle of the sliding seat 101 to enable it to have the function of telescoping up and down. The upper end of the sliding seat 101 is horizontally slidably connected to the slide 4. A slide groove is provided at the lower end of the sliding seat 101. The upper end of the longitudinal beam gripper 102 is horizontally slidably connected in the slide groove. The extension direction of the slide groove is perpendicular to the slide 4 on the horizontal plane. The lower end of the longitudinal beam gripper 102 is fixedly connected to two longitudinal beam rods 9. The two ends of the longitudinal beam rod 9 are detachably connected to the support leg 6. One side of the mechanical arm 7 is detachably connected to the side of the support leg 6. The longitudinal beam frame 10 can arrange the longitudinal beam rod 9 at the side channel position and the upper roller group 8 on the longitudinal beam rod 9 to the set position through lateral extension and contraction, vertical lifting and lowering, and longitudinal movement.

[0026] The end of the arch frame 2 close to the self-moving machine tail 15 is fixedly connected with a first redirecting assembly 14, and the first redirecting assembly 14 includes a first redirecting frame, which is fixedly connected to one side of the lower end of the arch frame 2, and the first redirecting roller and the first redirecting roller are rotatably connected to the first redirecting frame. The first redirecting roller is arranged below the first redirecting roller, and the return part of the carrying tape 1 passes around the bottom of the first redirecting roller and the top of the first redirecting roller in turn, and then connects to the second redirecting assembly 11; Combination Figure 4 As shown, the second redirecting assembly 11 includes a second redirecting frame 111, which is slidably connected to the lower end of the slide 4, and the second redirecting frame 111 is rotatably connected with a second downward redirecting roller 112 and a second upward redirecting roller 113, the second downward redirecting roller 112 is arranged below the second upward redirecting roller 113, and the return portion of the carrying tape 1 sequentially passes over the upper part of the second upward redirecting roller 113 and the lower part of the second downward redirecting roller 112 and then connects to the lower roller group 12; The second redirecting assembly 11 has two sets of redirecting rollers, which cooperate with the two sets of redirecting rollers in the first redirecting assembly 14 arranged at the rear to change the direction of the return belt, thereby making room for the arrangement of the longitudinal beam rod 9 and the support leg 6.

[0027] Combination Figure 5 As shown, the upper end of the mounting frame 131 of the leg locking assembly 13 is slidably connected to the slide 4, the lower end of the mounting frame 131 is vertically telescopically connected to the transverse frame 132, and the lower end of the transverse frame 132 is horizontally slidably connected to the locking frame 133; the mounting frame 131 of the leg locking assembly 13 moves synchronously with the second redirecting assembly 11.

[0028] A plurality of longitudinal beams 9 are laid along the supporting tape 1 on the side of the machine head 5 , and supporting legs 6 are provided below the end-to-end portions of the plurality of longitudinal beams 9 , and supporting legs 6 are also provided at the ends of the longitudinal beams 9 at the end and end positions.

[0029] An anti-slip load-bearing roller 3 is provided at the upper end of the arch frame 2, and an upper roller group 8 is provided on the longitudinal beam rod 9. The anti-slip load-bearing roller 3 and the upper roller group 8 are used for laying the load-bearing tape 1. A lower roller group 12 is also provided in the middle of the supporting leg 6. The return part of the load-bearing tape 1 passes through the first redirecting component 14 and the second redirecting component 11 in sequence and is laid on the lower roller group 12.

[0030] When this embodiment is used: Combination Figure 1 , Figure 5 , Figure 6 As shown, when the conveyor is operating normally Figure 1 The fuselage longitudinal beam rod 9 is not connected to the tail, two sets of mechanical arms 7 fasten the last two pairs of support legs 6 of the fuselage, the self-moving tail 15 is connected to the fuselage through the arch frame 2, and the longitudinal beam frame 10 and the support leg positioning assembly 13 are in the empty position of the center line of the conveyor.

[0031] When the conveyor needs to be extended and the body is increased, the steps are as follows: In the first step, a pair of robotic arms 7 on the (left side) side of the nose 5 release the clamping of the supporting legs 6, rotate the vertical part of the robotic arms 7 (upper and lower telescopic arms) so that the horizontal part of the robotic arms 7 faces outward, and lift the group of robotic arms 7, and the self-moving tail 15 drives the arch frame 2 to move backward (to the right) for a distance of about 3 meters (about the length of a group of longitudinal beams 9). In this process, except that the original tail robotic arms 7 and the supporting legs 6 remain clamped and fixed, other parts move with the arch device frame. The robotic arms 7 (the robotic arms 7 on the original nose 5 side) after moving with the arch frame 2 coincide with the robotic arms 7 at the tail position. Since the robotic arms 7 and the robotic arms 7 are on different slides, they do not interfere with each other when they are staggered.

[0032] In the second step, the device of this embodiment is installed on the fuselage as follows Figure 6 After the arch frame 2 of the first step stops moving and stabilizes, the longitudinal beam frame 10 moves backward a little (to Figure 6 The longitudinal beam 9 with two upper roller groups 8 is manually placed on the gripper of the longitudinal beam device, and the gripper is lifted up to move the longitudinal beam 9 to the installation position (such as Figure 1 above the standard position shown.

[0033] In the third step, the working form of the leg positioning assembly 13 is similar to that of the longitudinal beam frame 10. The transverse moving frame 132 of the leg positioning assembly 13 drives the positioning frame 133 to extend to the side and descend. The supporting leg 6 with the lower roller is manually placed on the positioning frame 133 in the center (a support plate is provided on one side of the positioning frame 133 for supporting the supporting leg 6). The positioning frame 133 is raised and retracts the new supporting leg 6 to the center line position of the conveyor. The leg positioning assembly 13 descends to make the supporting leg 6 stand on the ground, and then the unfixed mechanical arm 7 is controlled to move along the slide of the slide frame 4 to the leg positioning assembly 13, so that one end of the cross arm of the mechanical arm 7 is reconnected with the new supporting leg 6.

[0034] In the fourth step, the longitudinal beam frame 10 is lowered so that the two ends of the longitudinal beam rod 9 are stuck on the supporting legs 6. Figure 7 As shown, subsequently, the longitudinal beam gripper 102 is released and raised, and the leg locking assembly 13 moves backward to the set position without affecting the next round of disassembly and assembly of the longitudinal beam rod 9 and the supporting leg 6. At this point, one set of fuselage installation is completed, and this set of actions is repeated if the installation continues.

[0035] To shorten the conveyor, the machine body needs to be dismantled, and the operation is just the opposite.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
