[0045] Two rotatable clamping rods 6 are mounted on the sliding plate 3, a bidirectional screw rod 33 is mounted in the sliding plate 3, the two clamping rods 6 are respectively connected with two sliding sleeves 34 on the bidirectional screw rod 33 through the base 5, one end of the bidirectional screw rod 33 is connected with a first motor 35, and the two clamping rods 6 move towards each other along the width direction of the sliding plate 3.

[0046] A rotating mechanism for driving the support rod to rotate is mounted in the base 5.

[0047] The rotating mechanism in the embodiment is a worm and gear mechanism, and a rotating motor can also be selected as the rotating driving device of the clamping rod 6.

[0048] A clearance 54 is formed in the base 5, one end of the clamping rod 6 extends into the base 5 through the clearance 54 and is connected with a worm gear 51, the worm gear 51 is rotatably mounted in the base 5 and is in transmission connection with a worm 52, and one end of the worm 52 is connected with a second motor 53.

[0050] The end of the clamping rod 6 away from the sliding plate 3 is provided with a limiting rod 65.

[0051] The inner side of the fixed rod 61 of the clamping rod 6 can be provided with a rubber pad layer, the outer side of the rubber pad layer is flush with the side of the base 5, and the rubber pad layer and the base 5 jointly clamp the module to be disassembled.

[0052] In addition, the fixed rod 61 can drive the telescopic rod 62 to extend or retract through the installation of a reciprocating driving device, and then drive the limiting rod 65 to extend or retract.

[0053] In the embodiment, the first motor 35 and the second motor 53 can be respectively installed on the sliding plate 3 and the base 5 through the mounting frame.

[0054] Working process: first, start the second motor 53 to make the clamping rod 6 rotate clockwise to the horizontal state with the sliding plate 3 through the worm gear 51 and the worm 52 mechanism, and then close the second motor 53.

[0055] Secondly, the operator holds the handrail 7 and pushes the tool, and pushes the bearing chassis 1 of the tool to the bottom of the module support to be disassembled.

[0056] Start the second motor 53 to make the clamping rod 6 rotate counterclockwise to the state of being nearly perpendicular to the sliding plate 3 through the worm gear 51 and the worm 52 mechanism, and in actual operation, the clamping rod 6 needs to be rotated by 85 degrees, and then the second motor 53 is closed, so that the two clamping rods 6 are located on both sides of the module to be disassembled.

[0057] Then, the operator holds the handle and rotates the hand wheel 22 clockwise, drives the first bevel gear 28 to rotate through the gear transmission mechanism, drives the second bevel gear 42 which is engaged with the first bevel gear 28 to rotate through the first bevel gear 28, and then drives the electric drive shaft 4 to rotate, and then drives the sliding plate 3 to adjust the height through the gear and rack 31 mechanism, and adjusts to the position corresponding to the middle height of the clamping rod 6 and the module to be disassembled, as shown in Figure 6

[0058] ​Start the first motor 35, the bidirectional lead screw 33 rotates, driving the two clamping rods 6 to move inward, thereby clamping the side of the module to be disassembled; loosen the locking knob 63, push the tooling so that the sliding plate 3 is close to the front side of the module to be disassembled, and tighten the locking knob 63 after it is aligned with the corresponding adjustment hole 64. At this time, the limit rod 65 and the sliding plate 3 achieve front and rear clamping of the module to be disassembled.

[0059] Finally, the operator grasps the handle 7 and pulls the tool to remove the module from the bracket, thus completing the module disassembly. The operator then grasps the handle and rotates the handwheel 22 counterclockwise, which in turn drives the first bevel gear 28 to rotate via the gear transmission mechanism. This, in turn, drives the second bevel gear 42, which meshes with the first bevel gear 28, to rotate. This, in turn, rotates the electric drive shaft 4, which, through the gear and rack mechanism 31, lowers the module, allowing it to land stably on the load-bearing chassis 1. Figure 7 As shown.

[0060] Example 2

[0061] like Figure 8 As shown, the difference between this embodiment and embodiment 1 is that: in this embodiment, the limiting rod 65 is rotatably connected to the end of the telescopic rod 62, a limited angle motor 66 is installed inside the telescopic rod 62, a connecting seat is provided at the end of the limiting rod 65, and a limiting block 67 that cooperates with the limiting port inside the telescopic rod 62 is installed on the connecting seat. The limiting port and the limiting end of the limiting block 67 are both circular, which can ensure that the limiting block 67 rotates within the limiting port. The driving end of the limited angle motor 66 is connected to a T-shaped block, and the limited angle motor 66 drives the rotation of the limiting rod 65.

[0062] In actual operation, the gap between adjacent modules or between a module and the side edge of the bracket may be small, making it difficult for the horizontal limiting rod 65 to move in and out. When a limited angle motor 66 is set, the limiting rod 65 is first swung to a vertical state and inserted into the gap to reach the rear of the module to be disassembled. Then, the limited angle motor 66 drives the limiting rod 65 to rotate to a horizontal state, thereby completing the subsequent clamping work.

[0063] By setting a limited-angle motor 66, the tooling can complete the clamping work when the gap between adjacent modules or between the module and the side edge of the bracket is small.

[0064] Example 3

[0065] like Figure 9 and Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment has a locking mechanism inside the support plate 2 for locking the first transmission gear 24. Preferably, the locking mechanism is installed between the first transmission gear 24 and the second transmission gear 27, which can avoid interfering with the operation of the toothed synchronous belt 25.

[0066] The locking mechanism comprises a pin sleeve 8 mounted inside the support plate 2, a pin shaft 81 is slidingly mounted in the pin sleeve 8, one end of the pin shaft 81 extends outside the pin sleeve 8 and is connected with a wedge-shaped locking block 82, the locking block 82 is matched with the tooth groove of the first transmission gear 24, a spring is arranged between the other end of the pin shaft 81 and the pin sleeve 8, a long slot 84 is formed in the pin sleeve 8, limit slot one 85 and limit slot two 86 are respectively formed at both ends of the long slot 84, the long slot 84, the limit slot one 85 and the limit slot two 86 penetrate the surface of the support plate 2, and a handle 83 extending outside the support plate 2 through the long slot 84 is mounted on the pin shaft 81.

[0067] When the operator needs to adjust the height by rotating the hand wheel 22, the handle 83 is pushed by fingers to drive the pin shaft 81 to move towards the spring direction, the handle 83 is clamped into the limit slot one 85 by rotating the handle 83, and at this time the pin shaft 81 will not be popped out of the pin sleeve 8 to lock the first transmission gear 24 due to the elastic force of the spring.

[0068] When the operator needs to temporarily lock the gear transmission mechanism after adjusting the height, the handle 83 is pushed by fingers to be separated from the limit slot one 85, the pin shaft 81 drives the locking block 82 to move towards the first transmission gear 24 under the action of the spring, the handle 83 is clamped into the limit slot two 86 by rotating the handle 83, and at this time the locking of the first transmission gear 24 is realized.

[0069] The temporary locking of the transmission mechanism is realized by setting the locking mechanism, the reverse driving of the gear and rack 31 mechanism and the gear transmission mechanism is avoided, and the use stability and safety are enhanced.

[0070] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
