The hydraulic mechanism is usually installed at a certain height from the ground. When the hydraulic mechanism needs to be disassembled and maintained, due to the large self-weight of the hydraulic mechanism, the disassembly, transfer and installation of the hydraulic mechanism are very inconvenient.

[0034] A hydraulic mechanism support removal tooling provided in this embodiment is shown in Figures 1-6 the figure. It includes a transfer vehicle 1. The transfer vehicle 1 includes two lower support rods 3. The two lower support rods 3 are connected by a first cross beam rod 31. An upper support rod 4 is arranged above the lower support rod 3. A first sliding groove 32 is arranged at one end of the lower support rod 3. A first rotating shaft 321 is slidably connected in the first sliding groove 32. One end of the first rotating shaft 321 is rotatably connected to one end of a first support rod 5. The other end of the first support rod 5 is rotatably connected to one end of the upper support rod 4 through a second rotating shaft 51. A second sliding groove 41 is arranged at the other end of the upper support rod 4. A third rotating shaft 411 is slidably connected in the second sliding groove 41. One end of the third rotating shaft 411 is rotatably connected to one end of a second support rod 6. The other end of the second support rod 6 is rotatably connected to the other end of the lower support rod 3 through a fourth rotating shaft 61. The middle parts of the first support rod 5 and the second support rod 6 are rotatably connected through a fifth rotating shaft 7. A second cross beam rod 71 is connected between the two second support rods 6. A hydraulic telescopic rod 8 is arranged between the first cross beam rod 31 and the second cross beam rod 71. One end of the hydraulic telescopic rod 8 is rotatably connected to the first cross beam rod 31. The other end of the hydraulic telescopic rod 8 is rotatably connected to the second cross beam rod 71. A pulley 33 is installed at the lower part of the lower support rod 3. The pulley 33 is used to cooperate with a track 2. A connecting plate 42 is arranged at the upper part of the upper support rod

[0033] 4. A support platform 43 is arranged on the upper end surface of the connecting plate 42. An arc concave surface is arranged at the upper end of the support platform 43.

[0035] In the above embodiment, two lower support rods 3 are connected by a first cross beam rod 31 to form the lower support surface of the transporter 1. An upper support rod 4 is arranged above the lower support rod 3, and a connecting plate 42 is arranged at the upper part of the upper support rod 4. Two upper support rods 4 are connected by the connecting plate 42 to form the upper support surface of the transporter 1. A hydraulic telescopic rod 8 is arranged between the first cross beam rod 31 and the second cross beam rod 71. Two lower support rods 3 are connected by the first cross beam rod 31. A second cross beam rod 71 is connected between two second support rods 6. One end of the hydraulic telescopic rod 8 is rotatably connected to the first cross beam rod 31, and the other end of the hydraulic telescopic rod 8 is rotatably connected to the second cross beam rod 71. As Figure 2 shown in the example, when the hydraulic telescopic rod 8 extends, the other end of the second support rod 6 is rotatably connected to the other end of the lower support rod 3 through a fourth rotating shaft 61. The hydraulic telescopic rod 8 pushes the second support rod 6 to rotate counterclockwise along the fourth rotating shaft 61, that is, the extended hydraulic rod pushes the second support rod 6 to deflect upward. The middle parts of the first support rod 5 and the second support rod 6 are rotatably connected through a fifth rotating shaft 7, so that the lower included angle between the first support rod 5 and the second support rod 6 becomes smaller. As Figure 3 shown in the example, it drives the first rotating shaft 321 rotatably connected to the end of the first support rod 5 to move rightward along the arrangement direction of the first sliding groove 32, and the third rotating shaft 411 rotatably connected to the end of the second support rod 6 to move rightward along the arrangement direction of the second sliding groove 41. As Figure 2 shown in the example, the bottom end of the first support rod 5 approaches the bottom end of the second support rod 6, and the top end of the second support rod 6 approaches the top end of the second support rod 6, increasing the vertical height of the first support rod 5 and the second support rod 6, that is, increasing the height of the upper support rod 4, realizing the lifting of the support platform 43 on the connecting plate 42. The single-end movement between the first support rod 5 and the second support rod 6 realizes the cross opening and closing between the support rods to change the vertical height. Compared with the prior art where the cross support rods move at both ends to realize the cross opening and closing of the support rods, the mobile ends of the support rods are reduced, which is beneficial to improving the stability of the support rods during movement. At the same time, the driving device required for movement is also correspondingly reduced, making it easier to operate during use. The hydraulic telescopic rod 8 is used to push multiple support rods for linkage support cooperation. Compared with directly using the hydraulic telescopic rod 8 for lifting, the bearing capacity and stability of the hydraulic telescopic rod 8 are improved, which is suitable for lifting hydraulic mechanisms with relatively large self-weights. In addition, a pulley 33 is installed at the lower part of the lower support rod 3, and the pulley 33 is used to cooperate with the track 2. Further, an arc-shaped concave surface is arranged at the upper end of the support platform 43, which can be used for limit adaptation of the hydraulic mechanism, and is beneficial to improving the stability of the hydraulic components during transportation.

[0036] In an embodiment of the present application, refer to Figure 2 as shown, it further includes a track 2 arranged below the transporter 1, and the pulley 33 is used to cooperate with the track 2.

[0037] In the above embodiments, due to the excessive self-weight of the hydraulic mechanism, the route is likely to deviate during the movement of the transporter 1. The track 2 can provide a stable and continuous transportation path, enabling the transporter 1 to efficiently transfer the hydraulic mechanism within the specified route. The transporter 1 running on the track 2 can more stably carry and transport goods, reducing the risk of damage to the components of the hydraulic mechanism caused by vibration or jolting.

[0038] In an embodiment of the present application, ground piles 21 are buried under the track 2.

[0039] In the above embodiments, due to the large self-weight of the hydraulic mechanism, the track 2 - carrying trolley will be subjected to a large pressure, causing the track 2 to sink. The ground piles 21 are used to support the track 2, providing a stable foundation for the track 2, preventing the track 2 from sinking under pressure, and enhancing the overall stability and durability of the structure of the track 2.

[0040] In an embodiment of the present application, refer to Figure 2 As shown, one end of the lower support rod 3 is connected with a handle 34.

[0041] In the above embodiments, the handle 34 provides a stable hand - holding point for the transporter 1, facilitating the staff to control the movement of the transporter 1 through the handle 34, preventing the transporter 1 from accidentally slipping out of control, reducing the accident risk, and improving the stability of the transporter 1 during movement.

[0042] In an embodiment of the present application, refer to Figure 2 As shown, the two ends of the two lower support rods 3 are connected by a crossbar 35.

[0043] In the above embodiments, the two ends of the two lower support rods 3 are connected by a crossbar 35. On the one hand, it can increase the connection part of the two lower support rods 3 to enhance the stability of the two lower support rods 3. On the other hand, the crossbar 35 can block one end of the first chute 32 of the lower support rod 3 to prevent the first rotating shaft 321 from slipping out of the first chute 32 during the movement in the first chute 32, thereby improving the stability of the transporter 1 during lifting.

[0044] In an embodiment of the present application, refer to Figure 2 As shown, a soft pad 431 is attached to the arc - shaped concave surface at the upper end of the support platform 43.

[0045] In the above embodiments, the soft pad 431 is used to reduce the surface hardness of the arc - shaped concave surface, avoiding scratches when the hydraulic mechanism contacts the arc - shaped concave surface. Optionally, the soft pad 431 can be selected as a rubber soft pad 431, which plays a role in anti - slipping and improving stability. In addition, the rubber soft pad 431 also plays an insulating role to prevent accidental electric leakage of the electric - hydraulic mechanism, which is beneficial to improving safety.

[0046] In one embodiment of the present application, refer to Figure 2 As shown, a stop block 331 is provided on one side of the pulley 33.

[0047] In the above embodiment, the stop block 331 is used to protect the pulley 33, preventing the pulley 33 from directly hitting an obstacle during the movement of the transporter 1 and causing damage to the pulley 33.

[0048] In one embodiment of the present application, refer to Figure 2 As shown, the support platform 43 and the connecting plate 42 are detachably connected.

[0049] In the above embodiment, the detachable connection between the support platform 43 and the connecting plate 42 facilitates the replacement of the support platform 43 with different-sized arc-shaped concave surfaces for fixed cooperation with different types of hydraulic mechanisms, which is beneficial to improving the adaptability of the transporter 1.

[0050] During the actual use of the present application: As Figure 5 and Figure 6 shown, the guide rail is laid under the hydraulic mechanism to be disassembled, and the transporter 1 is pushed under the hydraulic mechanism to be disassembled. When the hydraulic telescopic rod 8 extends, the other end of the second support rod 6 is rotatably connected to the other end of the lower support rod 3 through the fourth rotating shaft 61. The hydraulic telescopic rod 8 pushes the second support rod 6 to rotate counterclockwise along the fourth rotating shaft 61, that is, the extended hydraulic rod pushes the second support rod 6 to deflect upward. The middle parts of the first support rod 5 and the second support rod 6 are rotatably connected through the fifth rotating shaft 7, making the lower included angle between the first support rod 5 and the second support rod 6 smaller. As Figure 3 shown in the example, respectively drive the first rotating shaft 321 rotatably connected to the end of the first support rod 5 to move to the right along the setting direction of the first sliding groove 32, and the third rotating shaft 411 rotatably connected to the end of the second support rod 6 to move to the right along the setting direction of the second sliding groove 41. As Figure 2 shown in the example, make the bottom end of the first support rod 5 approach the bottom end of the second support rod 6, and make the top end of the second support rod 6 approach the top end of the second support rod 6, increasing the vertical height of the first support rod 5 and the second support rod 6, that is, increasing the height of the upper support rod 4, so as to realize the lifting of the support platform 43 on the connecting plate 42, making the support platform 43 abut against the hydraulic mechanism, then disassembling the hydraulic mechanism from the circuit breaker, the hydraulic mechanism is borne on the transporter 1, and then pulling the transporter 1 out along the track 2 to complete the removal of the hydraulic mechanism.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some 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.
