Description

Technical Field

[0001] This utility model relates to the field of bearing device technology, and in particular to a bearing device for assembling current transformers. Background Technology

[0002] A 220kV instrument transformer refers to an instrument transformer with a rated voltage of 220 kV. It is a key device used for measurement and protection in power systems. Traditional assembly requires multiple complex procedures: First, the instrument transformer mounting flange must be hoisted down from the riser using an overhead crane. After taking protective measures on the ground, it must be manually flipped over to ensure that the flange face is upward. Then, the insulation components and the instrument transformer are placed in sequence. After the tightening and pressing operations are completed, the instrument transformer model and number are recorded. Finally, the entire assembly must be flipped over again using the overhead crane hook, and after adjusting its position, it must be hoisted to the riser flange to complete the final assembly. The entire process involves overlapping procedures, repeated hoisting, and redundant operation steps, requiring extremely high coordination between manual labor and the overhead crane.

[0003] In existing technologies, traditional assembly processes rely too heavily on multiple lifting and turning operations. To reduce the number of turning operations, tooling capable of supporting insulating components, current transformers, and lifting flanges is used, giving it a stable structure and ease of operation. However, existing supporting tooling cannot automatically guide the position of the lifted current transformer, requiring manual assistance in positioning the current transformer and the supporting tooling. This poses a safety risk to workers who may be collided with or squeezed by the swaying lifting components. Utility Model Content

[0004] The purpose of this utility model is to solve the safety risks of workers being hit or squeezed in the prior art, and to propose a bearing device for assembling current transformers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bearing device for assembling a current transformer, comprising: a support component and a guide component, wherein the guide component includes a fixed bottom cylinder, a primary guide tube is fixedly connected to the top of the fixed bottom cylinder, a secondary guide tube is slidably connected to the inner wall of the primary guide tube, and a tertiary guide tube is slidably connected to the inner wall of the secondary guide tube.

[0006] Preferably, the primary guide tube, secondary guide tube, and tertiary guide tube are all arranged in a funnel shape.

[0007] Preferably, the support assembly includes a positioning square plate, on both sides of which a first long steel bar is welded, and on the other two sides of which a second long steel bar is welded.

[0008] Preferably, both ends of the two first long steel bars are welded with supporting steel bars, and a fixing frame is welded between the top ends of the four supporting steel bars.

[0009] Preferably, a laminated wood board is fixedly installed on the top of the fixed frame by bolts, and a positioning hole is provided in the middle of the top of the laminated wood board.

[0010] Preferably, the primary guide tube, secondary guide tube, and tertiary guide tube are movably disposed inside the positioning hole. The guiding assembly also includes a multi-stage electric telescopic rod, the top end of which is fixedly connected to an installation block. The installation block is fixedly installed on the inner wall of the tertiary guide tube by bolts. The multi-stage electric telescopic rod is disposed on the top of the positioning square plate.

[0011] Preferably, the outer surface of the laminated wood board is provided with four positioning grooves, each of which corresponds to one of the four sides of the fixing frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by activating the multi-stage electric telescopic rod, the first-stage guide pipe, the second-stage guide pipe, and the third-stage guide pipe are sequentially extended and raised. Under the positioning guidance of the first-stage guide pipe, the second-stage guide pipe, and the third-stage guide pipe, the lifting seat flange can reduce swaying and prevent workers from being bumped when approaching. It can also be automatically and accurately placed in the middle of the laminated wood board, avoiding the need for repeated manual adjustments when the placement is off-center. This solves the safety risk problem of workers facing collisions and squeezing of the hoisting parts.

[0013] 2. In this utility model, hollow square steel from the factory's inventory is used as the material to make a support frame. Then, laminated wooden boards are installed on top of the overall support frame. Before assembly, the insulating parts and current transformers are placed on the tooling according to the drawings. After ensuring that the parts are placed neatly, the current transformer model and number are recorded. The alignment between the current transformer and the riser flange is completed by using an overhead crane. The flange bolts are tightened at the positioning groove. Then, the whole assembly is lifted to the riser by the overhead crane to complete the final assembly. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1, such as Figures 1-4 As shown, this utility model provides a bearing device for assembling a current transformer, including: a support assembly 1 and a guide assembly 2. The guide assembly 2 includes a fixed bottom cylinder 201, a primary guide pipe 202 fixedly connected to the top of the fixed bottom cylinder 201, a secondary guide pipe 203 slidably connected to the inner wall of the primary guide pipe 202, and a tertiary guide pipe 204 slidably connected to the inner wall of the secondary guide pipe 203. The primary guide pipe 202, the secondary guide pipe 203, and the tertiary guide pipe 204 are all arranged in a bucket shape. The support assembly 1 includes a positioning square plate 101, and a multi-stage electric telescopic rod 205 is arranged on the top of the positioning square plate 101. The guide assembly 2 also includes a multi-stage electric telescopic rod 205, and an installation block 206 is fixedly connected to the top of the multi-stage electric telescopic rod 205. The installation block 206 is fixedly installed on the inner wall of the tertiary guide pipe 204 by bolts.

[0019] The overall effect of Embodiment 1 is that, during use, the lifting flange and the marked current transformer and insulation are suspended in the middle. By activating the multi-stage electric telescopic rod 205, it is extended, thereby causing the primary guide pipe 202, the secondary guide pipe 203, and the tertiary guide pipe 204 to unfold and rise sequentially. The outer diameter of the top of the tertiary guide pipe 204 is small, while the middle circular hole of the lifting flange is usually larger. Therefore, the middle circular hole of the lifting flange is easy to align with its top. Under the positioning guidance of the primary guide pipe 202, the secondary guide pipe 203, and the tertiary guide pipe 204, the suspended lifting flange and current transformer can reduce swaying, preventing workers from being bumped when approaching. It can also be automatically and accurately placed in the middle of the laminated wooden board 106, avoiding the need for repeated manual adjustments when the placement is off-center. This solves the safety risk of workers being hit or squeezed by the lifting components. After placement, the multi-stage electric telescopic rod 205 is activated again, causing it to drive the primary guide pipe 202 and the secondary guide pipe 203 back into the tertiary guide pipe 204.

[0020] Example 2, as Figures 1-4 As shown, the support assembly 1 includes a positioning square plate 101. First long steel bars 102 are welded to both sides of the positioning square plate 101, and second long steel bars 103 are welded to both sides of the positioning square plate 101. Support steel bars 104 are welded to both ends of the two first long steel bars 102. A fixing frame 105 is welded between the top ends of the four support steel bars 104. A laminated wood board 106 is fixedly installed on the top of the fixing frame 105 by bolts. A positioning hole 108 is opened in the middle of the top of the laminated wood board 106. Four positioning grooves 107 are opened on the outer surface of the laminated wood board 106. Each positioning groove 107 corresponds to the four sides of the fixing frame 105. The primary guide tube 202, the secondary guide tube 203 and the tertiary guide tube 204 are movably arranged inside the positioning hole 108.

[0021] The effect achieved by the entire embodiment 2 is as follows: When in use, hollow square steel from the factory inventory is used as the material to make a bracket. The bottom structure of the bracket consists of two first long steels 102 and two second long steels 103, forming a square frame structure. A positioning square plate 101 is welded in the middle to make the bottom of the bracket sufficiently strong. The fixing frame 105 is connected to the bottom structure by four supporting steels 104 to form a whole, forming a complete bracket. Then, the laminated wood board 106 is installed on the top of the whole bracket. Before assembly, the insulating parts and current transformers are placed on the tooling according to the drawings. After ensuring that the parts are placed neatly, the current transformer model and number are recorded. The alignment between the current transformer and the riser flange is completed by the overhead crane. The flange bolts are tightened at the positioning groove 107. Then, the whole assembly is lifted to the riser by the overhead crane to complete the final assembly.

[0022] Working Principle: In use, hollow square steel from the factory's inventory is used to construct a support frame. The bottom structure of the frame consists of two first long steel bars 102 and two second long steel bars 103, forming a square frame. A positioning square plate 101 is welded in the middle, ensuring sufficient stability at the bottom. Four supporting steel bars 104 connect the fixing frame 105 to the bottom structure to form a complete support frame. Then, laminated wood boards 106 are installed on top of the overall support frame. Before assembly, the insulation components and current transformers are placed on the tooling according to the drawings, ensuring neat arrangement. The current transformer model and serial number are recorded. An overhead crane is used to align the current transformer with the riser flange. The flange bolts are tightened at the positioning groove 107. Finally, the entire assembly is lifted to the riser by the overhead crane, completing the final assembly. In use, the riser flange, along with the marked current transformer and insulator, is lifted. By activating the multi-stage electric telescopic rod 205, it extends, causing the primary guide pipe 202, secondary guide pipe 203, and tertiary guide pipe 204 to unfold and rise sequentially. The top outer diameter of the tertiary guide pipe 204 is small, while the central hole of the riser flange is usually larger. Therefore, the central hole of the riser flange easily aligns with its top. Under the positioning guidance of the primary guide pipe 202, secondary guide pipe 203, and tertiary guide pipe 204, the lifted riser flange and current transformer can reduce swaying and can be automatically and accurately placed in the middle of the laminated wood board 106. After placement, by activating the multi-stage electric telescopic rod 205 again, it drives the primary guide pipe 202 and secondary guide pipe 203 to retract into the tertiary guide pipe 204.

[0023] The wiring diagram of the multi-stage electric telescopic pole 205 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the multi-stage electric telescopic pole 205 will not be explained in detail.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
