[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a box-type substation construction auxiliary lifting device provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of the structure of area A is shown; Figure 3 for Figure 1 The schematic diagram of the structure of the fixed plate part is shown; Figure 4 for Figure 1The structural schematic diagram of the hook cross-section diagram is a box-type substation construction auxiliary lifting device, comprising: a placement box 1, adjustment components 2 are arranged on both sides of the placement box 1, and a stabilizing component 3 is arranged at the bottom of the placement box 1;

[0024] The adjustment assembly 2 includes a connecting frame 21 which is mirror-imaged on both sides of the placement box 1. The inner sides of the two connecting frames 21 are both laterally rotatably provided with a bidirectional threaded screw 22. The peripheral sides of the two bidirectional threaded screws 22 are both slidable left and right along the length direction thereof. A connecting ring 24 is provided at the bottom of the two sliding blocks 23 and below the connecting frame 21.

[0025] The spacing between the grab ears of substations of different specifications is different. The rotation of the output end of the driving motor 28 drives the rotation of the connecting rod 26, and then drives the rotation of the two bidirectional threaded screws 22. In conjunction with the setting of the limit slide bar 25, the two sliding blocks 23 are driven to move relative to or apart, thereby driving the movement of the connecting ring 24 set at the bottom, so as to be suitable for the lifting of substations of different specifications.

[0026] The stabilizing component 3 includes a longitudinal plate 31 arranged at the bottom of the placement box 1, a fixed plate 32 is arranged at the bottom of the longitudinal plate 31, two rotating frames 33 are arranged on the upper and lower front sides of the fixed plate 32, a slide 34 is arranged on the inner side of the upper rotating frame 33 so as to be rotatable up and down, and a stabilizing plate 35 is rotatably arranged at the front end of the slide 34.

[0027] Two fixing plates 32 are arranged at the bottom of the longitudinal plate 31, and they are arranged in a mirror image. When the substation is hung, the extension of the output end of the telescopic rod 37 drives the sliding sleeve 36 to move on the slide cylinder 34, and then drives the slide cylinder 34 to gradually rise, so that the stabilizing plate 35 gradually approaches the front and rear sides of the substation, and finally supports the front and rear sides of the substation, avoiding the safety hazard caused by the substation swaying left and right when it is in the air.

[0028] A sliding sleeve 36 is provided on the peripheral side of the slide cylinder 34 so as to slide forward and backward along its length direction, and a telescopic rod 37 is provided on the inner side of the lower rotating frame 33 so as to rotate up and down. The telescopic end of the front side of the telescopic rod 37 is rotatably connected to the peripheral side of the sliding sleeve 36.

[0029] Limiting slide bars 25 are disposed laterally on the inner sides of the two connecting frames 21, and the circumferential side surfaces of the two limiting slide bars 25 are respectively slidably connected to the inner sides of the two sliding blocks 23, and the opposite ends of the two bidirectional threaded screws 22 penetrate the inner walls of the two connecting frames 21 and extend to the interior of the placement box 1.

[0030] A connecting rod 26 is vertically rotatably provided at the bottom of the inner wall of the placement box 1, and two groups of oblique teeth 27 are provided on the surrounding side of the connecting rod 26. The opposite ends of the two bidirectional threaded screws 22 are fixedly connected to one side of the corresponding oblique teeth 27. A driving motor 28 is provided at the top of the inner wall of the placement box 1, and the output end at the bottom of the driving motor 28 is fixedly connected to the top of the connecting rod 26.

[0031] A hook 4 is provided on the top of the storage box 1 , and the left and right sides of the hook 4 are fixedly connected to the tops of the two connecting frames 21 through steel cables, and a hook 29 is provided at the bottom of the connecting ring 24 .

[0032] A slot 5 is provided on the inner side of the hook 29, and a closed ring 6 is provided on the inner side of the slot 5 so as to slide along the slot 5. A spring 7 is provided on the top of the left side of the closed ring 6 and inside the slot 5, and a semicircular stopper 8 is provided on the inner side of the closed ring 6.

[0033] When the hook 29 is hooked at the grab ear of the substation, the semicircular stopper 8 is pushed away, thereby driving the closing ring 6 to slide on the inner side of the slot 5, so that one end of the closing ring 6 abuts against the top of the right side of the hook 29 to close the hook 29, completely avoiding the problem of unhooking that may occur when the substation is in the air.

[0034] The working principle of the auxiliary lifting device for box-type substation construction provided by the utility model is as follows:

[0035] Step 1: When in use, according to the spacing between the two grab ears of the substation, adjust the spacing between the two connecting rings 24, drive the connecting rod 26 to rotate by the rotation of the output end of the driving motor 28, and then drive the two bidirectional threaded screws 22 to rotate, cooperate with the setting of the limit slide bar 25, drive the two sliding blocks 23 to move relative or apart, and thus drive the movement of the connecting ring 24 set at the bottom, so as to be suitable for the lifting of substations of different specifications;

[0036] Step 2: Hang the hook 29 on the grab ear. When the hook 29 is hooked on the grab ear of the substation, the semicircular stopper 8 is pushed open, thereby driving the closed ring 6 to slide inside the slot 5, so that one end of the closed ring 6 abuts against the top of the right side of the hook 29 to close the hook 29, completely avoiding the problem of decoupling that may occur when the substation is in the air;

[0037] Step 3: When the substation is hung, the extension of the output end of the telescopic rod 37 drives the sliding sleeve 36 to move on the slide cylinder 34, and then drives the slide cylinder 34 to gradually lift up, so that the stabilizing plate 35 gradually approaches the front and rear sides of the substation, and finally supports the front and rear sides of the substation, avoiding the safety hazard caused by the substation swaying left and right when it is in the air.

[0038] Compared with the related art, the auxiliary lifting device for box-type substation construction provided by the utility model has the following beneficial effects:

[0039] The extension of the output end of the telescopic rod 37 drives the sliding sleeve 36 to move on the slide cylinder 34, and then drives the slide cylinder 34 to gradually rise, so that the stabilizing plate 35 gradually approaches the front and rear sides of the substation, and finally supports the front and rear sides of the substation, avoiding the safety hazard caused by the substation swaying left and right when it is in the air, and the possible unhooking problem is avoided by the setting of the hook 29, which greatly reduces the safety hazard caused by the use of the lifting device.
