The vertical beam is fixedly connected to the support plate 1, and the horizontal beam is connected to the top of the telescopic rod II 7. The bottom ends of the two telescopic rods II 7 located on the same side of the support plate 1 are connected by a sliding rod 8. Each sliding rod 8 has a connecting plate 9 at its first end and a slider 11 slidingly sleeved on the outside of each sliding rod 8. The connecting plate 9 and the slider 11 are connected by a telescopic rod III 10. The support box 13 is located between the two sliders 11, and the support box 13 and the sliders 11 are connected by a connecting rod 12. The first ends of the two support rods 14 are located inside the support box 13, and the second ends are located outside the support box 13. The rotating assembly includes a rotating shaft 15, a turntable 16, and a rotating shaft drive. The turntable 16 is located above the support plate 1. The rotating shaft 15 is rotatably connected to the support plate 1 and fixedly connected to the turntable 16, and is driven to rotate by the rotating shaft drive.

[0027] Move the multi-functional auxiliary tool for coal mine equipment maintenance to the side of the coal mine equipment to be maintained, with the second end of the support rod 14 facing the equipment. First, control the retraction of the telescopic rod I3, causing the slide plate 4 to move the roller 5 upward, so that the telescopic box 2 is in contact with the ground. Keep the multi-functional auxiliary tool for coal mine equipment maintenance stationary. Then, control the retraction of the telescopic rod II7, causing the slide rod 8, slider 11, connecting rod 12, and support box 13 to move upward, so that the support rod 14 rises away from the turntable 16. The telescopic rod II7 stops retracting, and the telescopic rod III10 extends, causing the slider 11, connecting rod 12, and support box 13 to pass over the turntable 16. The telescopic rod III10 stops extending, and the telescopic rod II7 extends. The sliding rod 8, slider 11, connecting rod 12, and support box 13 are moved downwards, bringing the support rod 14 as close to the ground as possible. Telescopic rod II 7 stops extending, and then telescopic rod III 10 continues to extend, inserting the support rod 14 under the coal mine equipment to be repaired. Telescopic rod II 7 is then retracted, moving the coal mine equipment to be repaired upwards. Telescopic rod III 10 is then retracted, moving the equipment above the turntable 16. Telescopic rod II 7 is then extended, placing the equipment on the turntable 16. Telescopic rod III 10 continues to retract, disengaging the support rod 14 from the equipment. The angle of the equipment is adjusted by rotating the turntable 16. This multi-functional auxiliary tool for coal mine equipment repair mechanizes the lifting, moving, angle, and height adjustment of the equipment, reducing the labor intensity of maintenance personnel, improving safety and repair efficiency, and ensuring normal coal mine production.

[0028] The aforementioned multi-functional auxiliary tool for coal mine equipment maintenance also includes a clamping assembly; the clamping assembly includes a telescopic rod IV 17, a clamping plate 18, an arc plate 19, an elastic plate 20, and a straight plate 21; two clamping plates 18 are symmetrically arranged on both sides of the rotating shaft 15 and the turntable 16, each clamping plate 18 is connected to the rotating shaft 15 through the telescopic rod IV 17, an arc plate 19 is installed on the opposite sides of the two clamping plates 18, an elastic plate 20 is installed on the opposite sides of the two arc plates 19, and a straight plate 21 slides through each arc plate 19, and the two straight plates 21 are arranged in parallel.

[0029] The telescopic rod IV17 retracts, causing the two clamping plates 18 to move closer together. When the coal mining equipment to be repaired is cylindrical, the straight plate 21 is pulled out, and the curved plate 19 applies pressure to the elastic plate 20, causing the elastic plate 20 to fit against the cylindrical coal mining equipment, thus achieving clamping. When the coal mining equipment to be repaired is square, the straight plate 21 is inserted into the curved plate 19, and the straight plate 21 applies pressure to the elastic plate 20, causing the elastic plate 20 to fit against the square coal mining equipment, thus achieving clamping. The elastic plate 20 can deform, allowing it to better fit against the surface of the coal mining equipment to be repaired, increasing friction and preventing scratches on the surface of the coal mining equipment to be repaired.

[0030] The aforementioned multi-functional auxiliary tool for coal mine equipment maintenance also includes a limiting component; the bottom surface of the turntable 16 is evenly provided with several limiting grooves 22 around the center; the limiting component is located between the support plate 1 and the turntable 16, and includes a top rod 23, a spring 24, a sleeve 25 and a pressure plate 26; the bottom end of the sleeve 25 is connected to the support plate 1, and a sliding groove is provided on the side; the top rod 23 is slidably connected to the sleeve 25, with its bottom end located inside the sleeve 25 and its top end located outside the sleeve 25; the spring 24 is located inside the sleeve 25, and its two ends are connected to the top rod 23 and the support plate 1 respectively; the pressure plate 26 passes through the sliding groove, and its end located inside the sleeve 25 is fixedly connected to the top rod 23.

[0031] When it is necessary to rotate the coal mining equipment to be inspected, move the pressure plate 26 downward. The pressure plate 26 drives the top rod 23 to move downward. The top rod 23 disengages from the limiting groove 22. Then rotate the turntable 16. After rotating to the appropriate position, release the pressure plate 26. Under the action of the spring 24, the top rod 23 moves upward and engages with the inside of the limiting groove 22, thereby achieving the effect of engaging and fixing the turntable 16.

[0032] In the aforementioned multi-functional auxiliary tool for coal mine equipment maintenance, a push rod 27 is fixedly installed on the support plate 1, and a control panel 28 and a toolbox 29 are fixedly installed on the push rod 27.

[0033] The push rod 27 is set to facilitate the pushing of the support plate 1, and the control panel 28 can control the operation of each telescopic rod and drive component.

[0034] The aforementioned multi-functional auxiliary tool for coal mine equipment maintenance also includes a drive assembly; the drive assembly includes a stabilizing plate I 30, a connecting shaft I 31, a track 32, a connecting shaft drive component 33, a stabilizing plate II 34, a crossbar 35, a telescopic rod V 36, a U-shaped frame 37, and a connecting shaft II 38; two stabilizing plates I 30 are fixedly installed on the support plate 1; both ends of the connecting shaft I 31 are rotatably connected to the two stabilizing plates I 30 respectively, and are driven to rotate by the connecting shaft drive component, with fixed components on the connecting shaft I 31. A drive tooth I is fitted on the support plate 1; two stabilizing plates II 34 are fixedly installed on the support plate 1; the two ends of the crossbar 35 are rotatably connected to the two stabilizing plates II 34 respectively; the top end of the telescopic rod V 36 is rotatably fitted on the crossbar 35, and the bottom end is fixedly connected to the U-shaped frame 37; the two ends of the connecting shaft II 38 are rotatably connected to the two ends of the U-shaped frame 37, and the drive tooth II is fixedly fitted on the connecting shaft II 38; the track 32 is fitted on the drive tooth I and the drive tooth II, and meshes with the drive tooth I and the drive tooth II.

[0035] When the machine needs to be moved, the connecting shaft drive 33 is activated, driving the connecting shaft I 31 and the drive gear I fixed on the connecting shaft I 31 to rotate, which in turn drives the track 32 to rotate. The track 32 then contacts the ground, thus driving the machine to move. When movement is not required, the telescopic rod V 36 retracts, causing the U-shaped frame 37 and the connecting shaft II 38 to move upward, thus moving the track 32 away from the ground. The machine can be steered by cooperating with the push rod 27.

[0036] Among the aforementioned multi-functional auxiliary tools for coal mine equipment maintenance, a bidirectional hydraulic rod is installed inside the support box 13; two support rods 14 are respectively connected to the two output ends of the bidirectional hydraulic rod.

[0037] The distance between the two support rods 14 is adjusted by a bidirectional hydraulic rod to accommodate coal mine equipment of different sizes to be repaired, ensuring the stability of the coal mine equipment after it is supported.

[0038] Among the aforementioned multi-functional auxiliary tools for coal mine equipment maintenance, the top surface of the turntable 16 has two grooves for accommodating the support rod 14.

[0039] After the coal mine equipment to be repaired is placed on the turntable 16, the support rod 14 is embedded in the slide groove. Then, the telescopic rod Ⅲ10 is controlled to continue to retract, so that the support rod 14 is pulled out of the slide groove, thereby separating the support rod 14 from the coal mine equipment to be repaired.

[0040] In the aforementioned multi-functional auxiliary tool for coal mine equipment maintenance, the top surface of the support rod 14 is provided with several anti-slip grooves and several slots, and a limit rod is movably inserted into the slot; a baffle is fixedly installed on the support box 13, and the baffle is perpendicular to the support rod 14.

[0041] By creating several anti-slip grooves on the support rod 14, an anti-slip effect can be achieved, preventing slippage when raising the coal mining equipment to be repaired. After inserting the support rod 14 under the coal mining equipment to be repaired, the limiting rod is inserted into the slot, cooperating with the baffle to fix the coal mining equipment to be repaired. This can prevent the coal mining equipment to be repaired from falling during movement, and can also determine whether binding and fixing are necessary based on the size of the coal mining equipment to be repaired.

[0042] In the aforementioned multi-functional auxiliary tool for coal mine equipment maintenance, the L-shaped plate 6 is fixedly connected to the support plate 1, and the telescopic box 2 is fixedly connected to the L-shaped plate 6.

[0043] In this embodiment, the telescopic rod is a hydraulic rod, and both the rotating shaft drive and the connecting shaft drive 33 are motors or electric motors.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
