[0051] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0052] like Figure 1-7 As shown, the utility model is a bushing workpiece handling assisting arm for a high-voltage switch cabinet, which is used to carry a wall bushing 8, and includes a lifting arm 1, a fixing frame 2, a lifting frame 3, a lifting cylinder 4, a clamp 5, a turning cylinder 6 and an adjusting cylinder 7.

[0053] The boom 1 is a crane or other equipment used for lifting operations. The crane utilizes the lever principle and a lifting device to lift other components.

[0054] The fixing frame 2 is used to fix and carry other components. The fixing frame 2 is fixedly arranged on the boom 1 and is raised and lowered along with the raising and lowering of the boom 1 .

[0055] The lifting frame 3 is used to carry the clamp 5 . The lifting frame 3 is slidably disposed on the fixed frame 2 and slides in a vertical direction relative to the fixed frame 2 .

[0056] The lifting cylinder 4 is used to drive the lifting frame 3 to move up and down. The lifting cylinder 4 is fixedly arranged on the fixed frame 2, and its output end is rotatably connected with the lifting frame 3. Figure 2 As shown, when the lifting cylinder 4 is extended, it drives the lifting frame 3 to descend, and conversely, it drives it to move upward.

[0057] The clamp 5 is used to clamp the wall sleeve 8. The clamp 5 is rotatably arranged on the lifting frame 3 and can be adjusted according to the placement angle and state of the wall sleeve 8, so that the clamp 5 can adapt to different working conditions.

[0058] The flip cylinder 6 is used to control the angle of the fixture 5. The flip cylinder 6 is rotatably arranged on the lifting frame 3, and its output end is rotatably connected to the fixture 5; Figure 2 As shown, when the clamp 5 clamps the wall bushing 8, the expansion and contraction of the flip cylinder 6 can be used to control the clamping angle and placement angle of the wall bushing 8, so that the vertically placed wall bushing 8 can be horizontally entered into the side wall of the high-voltage switch cabinet. The expansion and contraction of the lifting cylinder 4 can also be used to lift the wall bushing 8 to avoid the problem of collision with the high-voltage switch cabinet due to movement in the horizontal position, making the transport assist arm more suitable for bushing transport operations in the field of high-voltage switch cabinets.

[0059] The structure of the wall bushing 8 is as follows: Figure 7 As shown, it includes an intermediate plate 81 and two sleeves 82. The two sleeves 82 are relatively arranged on both sides of the intermediate plate 81, and their outer diameters are smaller than the outer diameter of the intermediate plate 81. A corrugated groove 801 is provided on the outer side of the sleeve 82. In order to improve the clamping firmness and clamping safety of the clamp 5, the clamp 5 includes a fixed seat 51, two clamping plates 52, two clamping cylinders 53, a supporting plate 54, a positioning column 55, a supporting rod 56 and two contoured sleeves 57.

[0060] The fixed seat 51 is rotatably arranged on the lifting frame 3 and is rotatably connected to the output end of the flip cylinder 6; the clamping plate 52 is slidably arranged on the fixed seat 51, and the two clamping plates 52 are arranged opposite to each other; the clamping cylinder 53 is fixedly arranged on the fixed seat 51, and its output end is fixedly connected to the clamping plate 52, and the clamping cylinder 53 corresponds to the clamping plate 52 one by one. The two clamping cylinders 53 can drive the two clamping plates 52 to move relative to each other, so as to clamp and fix the sleeve 82; Figure 3 As shown, when the two clamping cylinders 53 are extended, the two clamping plates 52 can be driven to move away from each other. Conversely, the two clamping plates 52 can be driven to move closer together, thereby achieving clamping and fixing of the wall sleeve 8.

[0061] The abutment plate 54 is fixedly arranged on the fixing seat 51, and is used to abut against the end of the sleeve 82; the positioning column 55 is fixedly arranged on the side of the abutment plate 54 away from the fixing seat 51, and is used to be inserted into the sleeve 82. When the clamp 5 clamps the wall sleeve 8, the positioning column 55 is first inserted into the interior of the sleeve 82, so that the clamp 5 can be initially positioned, and the top of the wall sleeve 8 can also be positioned by utilizing the abutment between the abutment plate 54 and the end of the sleeve 82, so that the clamping position of the clamp 5 and the wall sleeve 8 is consistent.

[0062] One end of the supporting rod 56 is fixed on the fixing seat 51, and the other end is used to support the middle plate 81. During transportation, there may be a problem that the clamp 5 moves down too far and damages the wall sleeve 8. When the supporting rod 56 abuts against the middle plate 81, it means that the clamp 5 cannot move down further, thereby playing a certain safety protection role.

[0063] The two contoured sleeves 57 are respectively fixed on the two clamping plates 52, and the inner sides thereof correspond to the shape of the corrugated groove 801, so that the fixing firmness of the clamp 5 and the wall sleeve 8 is higher; specifically, two abutting rods 56 are provided, and the two abutting rods 56 and the two contoured sleeves 57 are arranged in a circular array about the center line of the positioning column 55 and are alternately arranged, so as to realize the encirclement of the wall sleeve 8 and prevent it from tilting during the clamping process.

[0064] In order to realize the sliding of the fixed frame 2 and the lifting frame 3, as Figure 4 As shown, the fixed frame 2 includes a fixed bracket 21 and a rectangular tube 22, and the lifting frame 3 includes a lifting bracket 31 and a guide rail 32. The fixed bracket 21 is fixedly arranged on the lifting arm 1; the rectangular tube 22 is fixedly arranged on the fixed bracket 21; the lifting bracket 31 is rotatably connected to the output end of the lifting cylinder 4; the guide rail 32 is fixedly arranged on the lifting bracket 31, which penetrates and is slidably arranged in the rectangular tube 22. A slider can be arranged in the rectangular tube 22, and the slider and the guide rail 32 are used to slide. When the lifting cylinder 4 is extended or retracted, the lifting bracket 31 and the fixed bracket 21 can be driven to slide. At the same time, the guide rail 32 is located in the rectangular tube 22, and it is not easy to cause derailment, which is beneficial to ensuring the safety of the device.

[0065] An operation panel 33 needs to be provided in the device to electrically control each mechanism.

[0066] The adjusting cylinder 7 is used to adjust the position of the operating panel 33, and the operating panel 33 is slidably arranged on the lifting bracket 31; the adjusting cylinder 7 is rotatably arranged on the lifting bracket 31, and its output end is rotatably connected to the operating panel 33, such as Figure 4 As shown, when the clamp 5 is lifted, the adjusting cylinder 7 can be extended to allow the operation panel 33 to be lowered, and vice versa, to allow the operation panel 33 to be lifted, thereby keeping the height of the operation panel 33 unchanged during the up and down movement of the clamp 5.

[0067] In order to improve the safety of the device, the lifting frame 3 further includes a buffer rod 34 and two nuts 35, wherein the buffer rod 34 passes through the lifting bracket 31 and is used to selectively resist the clamp 5; the nut 35 is connected to the outer side of the buffer rod 34 through threaded fitting, and the two nuts 35 are relatively arranged on both sides of the lifting bracket 31; Figure 5As shown, when the clamp 5 rotates to a certain position, the buffer rod 34 and the clamp 5 are abutted to prevent it from continuing to rotate, and the position of the buffer rod 34 can be adjusted by rotating the nut 35, thereby adjusting the abutment angle of the clamp 5.

[0068] The fixed support 21 includes a first support arm 211, a second support arm 212 and two positioning cylinders 213. The first support arm 211 is rotatably arranged on the lifting arm 1; the second support arm 212 is rotatably arranged on the first support arm 211 and connected to the lifting support 31; the two positioning cylinders 213 are both fixedly arranged on the first support arm 211, and the output ends of the two positioning cylinders 213 selectively abut against the second support arm 212 and the lifting arm 1, respectively. Figure 6 As shown, by rotating the first arm 211, the second arm 212 and the boom 1, the clamp 5 can be moved horizontally, and by controlling the extension and retraction of the positioning cylinder 213, the relative positions of the first arm 211, the second arm 212 and the boom 1 can be fixed.

[0069] The method of using the bushing workpiece handling assisting arm for high-voltage switch cabinet of the utility model is as follows:

[0070] First, the position of the lifting arm 1, the fixed frame 2 and the lifting frame 3 are adjusted to move the clamp 5 to the wall bushing 8 placed on the ground, and then the clamp 5 is clamped to clamp the wall bushing 8. Finally, the clamp 5 and the wall bushing 8 clamped therein are turned 90 degrees by controlling the turning cylinder 6 and the lifting cylinder 4, and lifted vertically upward to be inserted into the side wall of the high-voltage switch cabinet; during this period, the height of the operating panel 33 can also be kept unchanged by controlling the adjusting cylinder 7.
