[0029] In the application, the channel steel support 1 provided with the lifting assembly 5 and the angle adjusting assembly 6 is placed above a device cover shell, one end of the lifting assembly 5 is inserted into the device cover shell through a maintenance opening in the top of the device cover shell, the rear supporting leg to be hooked is found, the screw rod 51 is driven by using the mobility between the ball head 62 and the fixed seat 61, the lifting hook 53 is connected with the rear supporting leg (a lifting ring can also be installed on the rear supporting leg and matched with the lifting hook 53), then the rotating handle 52 is rotated to drive the screw rod 51 to rotate, the ball head 62 is limited by the first ball 63 and cannot rotate with the screw rod 51, the screw rod 51 drives the lifting hook 53 to ascend, so that the rear supporting leg can be easily lifted by one person, and another person can complete the replacement of the belt below.

[0030] In an embodiment, two supporting parts 2 are further included, a sinking groove 3 for placing the supporting part 2 is arranged at the bottom of the channel steel support 1, and an anti-toppling assembly 4 located in the sinking groove 3 is arranged between the channel steel support 1 and the supporting part 2; the supporting part 2 comprises a supporting plate 21, a first spring 22 is arranged between the top of the supporting plate 21 and the channel steel support 1, and the sum of the height of the first spring 22 and the supporting plate 21 is greater than the groove depth of the sinking groove 3 when the channel steel support 1 is not stressed; the anti-toppling assembly 4 comprises a guide plate 41 arranged on the side of the two supporting plates 21 facing each other, the guide plate 41 is sleeved with a hooking plate 42 capable of reciprocating sliding along the guide plate 41, a linkage plate 43 is arranged between the top of the hooking plate 42 and the channel steel support 1, and the hooking plate 42 and the channel steel support 1 are both rotationally connected with the linkage plate 43.

[0031] In this way, by adding the support part 2 and the anti-toppling assembly 4 to the channel steel support 1, when the channel steel support 1 is not subjected to external force, the support part 2 supports the channel steel support 1, so that the channel steel support 1 is suspended, when the channel steel support 1 is lifted, the channel steel support 1 is pressed downward to overcome the thrust of the first spring 22, thereby driving the linkage plate 43 to push the hooking plate 42 to move along the guide plate 41 to one side of the support plate 21, so that the hooking plate 42 is hooked on the equipment cover, thereby avoiding the toppling problem caused by the gravity center deviation during lifting, and improving the safety of the maintenance process.

[0032] Preferably, different support parts 2 with different intervals are arranged for different types of carding machines to adapt to different widths of the maintenance opening on the equipment cover.

[0033] In an embodiment, a plurality of first limiting plates 7 limiting the moving direction of the support plate 21 are arranged in the sink 3, and the first limiting plates 7 are fixedly connected with the channel steel support 1, the number of each group of first limiting plates 7 is two, and the two first limiting plates 7 are distributed on the left and right sides of the support plate 21, and the interval between the two first limiting plates 7 is equal to the thickness of the support plate 21.

[0034] In this way, by limiting the moving direction through the first limiting plate 7, the stability of the channel steel support 1 during the lifting and lowering process is improved.

[0035] In an embodiment, a second limiting plate 8 limiting the sliding length of the hooking plate 42 is arranged at the end of the guide plate 41 away from the support plate 21.

[0036] In this way, by preventing the hooking plate 42 from separating from the guide plate 41 through the second limiting plate 8, it is ensured that the hooking plate 42 can be stably hooked on the equipment cover during use.

[0037] In an embodiment, the hooking plate 42 comprises a vertical plate 421, the vertical plate 421 is provided with a horizontal plate 422 away from the lifting assembly 5, the vertical plate 421 is provided with a through hole 423 matched with the guide plate 41, and the through hole 423 is provided with a second ball 424 embedded in the vertical plate 421.

[0038] In this way, the second ball 424 is used to reduce the friction of the vertical plate 421 moving on the guide plate 41.

[0039] In an embodiment, the bottom of the support plate 21 is provided with a third ball 211 for reducing the moving resistance of the support plate 21.

[0040] In this way, the third ball 211 is used to make the support plate 21 slide on the equipment cover, when the placement position of the channel steel support 1 deviates from the hooking point, the support plate 21 can drive the channel steel support 1 to move to the optimal lifting position under the influence of the gravity of the equipment when being hooked.

[0041] Preferably, the distance between the horizontal plate 422 and the third rolling ball 211 is not less than the thickness of the equipment cover, so as to avoid the situation that the horizontal plate 422 of the hooking plate 42 cannot be moved to the lower side of the equipment cover to complete the hooking.

[0042] In an embodiment, the screw rod 51 is provided with an extension assembly 9 for pushing the hook 53 away from the screw rod 51.

[0043] In this way, when there is a certain distance between the hook 53 and the rear supporting leg, the hook 53 can be connected to the rear supporting leg by the extension assembly 9, so that the maintenance personnel do not need to rotate the screw rod 51 to make the hook 53 close to the rear supporting leg, and the maintenance and replacement efficiency can be improved.

[0044] In an embodiment, the extension assembly 9 includes a center rod 91 capable of reciprocating in the screw rod 51, the height of the center rod 91 is greater than the height of the screw rod 51, one end of the center rod 91 is rotationally connected with the hook 53, and the other end is fixedly connected with an end plate 92.

[0045] The end plate 92 and the handle 52 are provided with a second spring 93 for pushing the end plate 92 to reset, the outer circumferential wall of the center rod 91 is provided with a linkage block 94 for linking the center rod 91 and the screw rod 51, the screw rod 51 is provided with a first sliding groove 511 and a plurality of second sliding grooves 512 for the up-and-down movement of the linkage block 94, and the screw rod 51 is further provided with a rotating groove 513 for the rotation of the linkage block 94 around the axis of the center rod 91, and the rotating groove 513 is communicated with the second sliding grooves 512 and the first sliding groove 511.

[0046] In this way, according to the distance between the hook 53 and the rear supporting leg, the maintenance personnel pushes the center rod 91 to move downward by a certain length, so that the linkage block 94 moves to the intersection point of the first sliding groove 511 and the rotating groove 513, then the center rod 91 is rotated, so that the linkage block 94 enters the rotating groove 513 and rotates along the rotating groove 513 until it cannot continue to rotate, then the second spring 93 pushes the end plate 92 to rise, so as to drive the linkage block 94 installed on the center rod 91 to be clamped into the second sliding groove 512, so that the center rod 91 can rotate together with the screw rod 51, at this time, the adjustment of the position of the hook 53 is completed, then the hook 53 can be connected with the rear supporting leg, and the screw rod 51 is rotated to lift the rear supporting leg.

[0047] Preferably, an indicating groove corresponding to the position of the rotating groove 513 is formed on the outer wall of the center rod 91, so as to facilitate the operator to judge whether the center rod 91 is pushed to the right position.
