Description

An adjustable power transmission device for power engineering construction Technical Field

[0001] This utility model relates to the field of power engineering construction technology, and in particular to an adjustable power transmission device for power engineering construction. Background Technology

[0002] In modern power engineering construction and maintenance, power transmission equipment, as the core equipment ensuring stable power transmission, directly affects the efficiency and safety of engineering construction. With the continuous expansion of power grid construction and the increasing diversification of cable and wire specifications, construction sites are placing higher demands on the flexibility and applicability of power transmission equipment. This applies to everything from overhead power line installation and underground cable laying to substation equipment connections.

[0003] Existing power transmission devices used in power engineering construction mostly employ fixed-spacing clamp structures or single-specification clamping components. Their mechanical structure primarily consists of rigid supports, fixing bolts, or hydraulically driven grippers. The technical principle involves manually tightening the bolts to adjust the clamp spacing, or using a hydraulic system to control the opening and closing of the grippers to secure the power lines. While some devices possess some adjustment capabilities, the adjustment process relies on manual measurement and repeated adjustments, making operation cumbersome and inefficient. Furthermore, some devices adopt a modular design, adapting to different specifications of clamp modules to fit the power lines, but this undoubtedly increases equipment purchase costs and storage space requirements.

[0004] However, existing power transmission devices generally suffer from the inability to automatically adapt to wires of different diameters. In actual construction, the same project often requires handling wires of various specifications. Traditional devices, lacking adaptive adjustment capabilities, require construction workers to frequently adjust the clamp spacing manually. This not only consumes a lot of time and energy but also easily leads to clamp loosening or component wear during repeated adjustments, reducing the stability and reliability of the device. If the clamps do not properly adapt to the wires, it can also cause safety hazards such as wire slippage and poor contact, seriously affecting the progress and quality of power engineering construction. Therefore, an adjustable power transmission device for power engineering construction is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an adjustable power transmission device for power engineering construction, which aims to improve the problem that the existing technology cannot automatically adapt to wires of different diameters and requires frequent manual adjustment of the clamp spacing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable power transmission device for power engineering construction includes a base and a support plate. A bracket is fixedly connected to the top of the base, a driving component is provided at the bottom of the bracket, a first hollow column is fixedly connected to the top of the bracket, the bottom of the support plate is provided at the top of the base, and a connecting component is provided at the top of the support plate.

[0008] The connecting assembly includes a hollow block, the bottom of which is fixedly connected to the top of a support plate. A fixed column is slidably connected inside the hollow block. A spring is provided on the outer wall of the fixed column. One end of the spring is fixedly connected to the inner wall of the hollow block, and the other end of the spring is fixedly connected to the outer wall of the fixed column. A handle is fixedly connected to one end of the fixed column, and a clamping plate is fixedly connected to one end of the fixed column.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes a motor, the bottom of which is fixedly connected to the bottom of the bracket, and a screw is fixedly connected to the output end of the motor.

[0011] As a further description of the above technical solution:

[0012] The screw has a first nut threadedly connected to its outer wall, and a second hollow column is fixedly connected to the outer wall of the first nut.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the first nut is threaded with a third threaded sleeve, and the outer wall of the third threaded sleeve is threaded with a second nut.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the third threaded sleeve is fixedly connected to a third hollow column, and the outer wall of the second nut is fixedly connected to a second threaded sleeve.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the second threaded sleeve is threadedly connected to the first threaded sleeve, and the top of the first threaded sleeve is fixedly connected to the top cover, which is fixedly connected to the bottom of the support plate.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the second hollow column is slidably connected to the inner wall of the first hollow column, and the inner wall of the second hollow column is slidably connected to the outer wall of the third hollow column.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the first threaded sleeve is slidably connected to the inner wall of the third hollow column, the outer wall of the second threaded sleeve is disposed on the inner wall of the first threaded sleeve, and the inner wall of the first threaded sleeve is disposed on the outer wall of the third threaded sleeve.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pulling the handle to move the fixed column, the clamping plate is slid, and then the spring on the outer wall is retracted, achieving the effect of adaptively clamping wires of different sizes. This solves the problem of not being able to automatically adapt to wires of different diameters and requiring frequent manual adjustment of the clamp spacing, thus improving the stability of the adjustable power transmission device used in power engineering construction.

[0025] 2. In this utility model, the rotation of the screw will drive the first nut to move, causing the second hollow column to slide on the inner wall of the first hollow column. Then, the second threaded sleeve will be driven to rotate, which in turn will drive the third hollow column to move. The third hollow column will then drive the second nut to rotate, causing it to move on the outer wall of the third threaded sleeve. Subsequently, the first threaded sleeve and the top cover will move, achieving the effect of height adjustment. This solves the problem that the device cannot adapt to the height requirements of different construction scenarios, can only be used at a fixed height, and requires additional support for complex terrain, thus limiting its adaptability. This improves the practicality of the adjustable power transmission device for power engineering construction. Attached Figure Description

A handle 16 is fixedly connected to one end of the fixed post 17. Pulling the handle 16 allows the fixed post 17 to slide inside the hollow block 15. The fixed post 17 drives the clamping plate 19 at one end to move. At the same time, the movement of the fixed post 17 causes the spring 18 on the outer wall to contract. The spring 18's rebound force resets the clamping plate 19, thus achieving an adaptive clamping effect for wires of different sizes. The clamping plate 19 is fixedly connected to one end of the fixed post 17.

[0037] Referring to Figures 1, 4, and 5, the drive assembly includes a motor 5. The output end of the motor 5 drives the screw 6 to rotate. The first nut 8, threadedly connected to the outer wall of the screw 6, moves when the screw 6 rotates. The first nut 8 drives the second hollow column 7 to slide inside the first hollow column 4. Simultaneously, the rotation of the first nut 8 drives the third threaded sleeve 13 on the outer wall to rotate. The third threaded sleeve 13 drives the second nut 12 on the outer wall to rotate. The second nut 12 drives the third hollow column 9 on the outer wall to move. The rotation of the third hollow column 9 drives the first threaded sleeve 10 on the inner wall to move on the outer wall of the second threaded sleeve 11, thereby driving the top cover 14 and the support plate 3 to move, achieving the effect of height adjustment. The bottom of the motor 5 is fixedly connected to the bottom of the bracket 2. The output end of the motor 5 is fixedly connected to the screw 6. The outer wall of the screw 6 is threadedly connected to the first nut 8. A second hollow column 7 is fixedly connected. A third threaded sleeve 13 is threadedly connected to the outer wall of the first nut 8. A second nut 12 is threadedly connected to the outer wall of the third threaded sleeve 13. A third hollow column 9 is fixedly connected to the outer wall of the third threaded sleeve 13. A second threaded sleeve 11 is fixedly connected to the outer wall of the second nut 12. A first threaded sleeve 10 is threadedly connected to the outer wall of the second threaded sleeve 11. A top cover 14 is fixedly connected to the top of the first threaded sleeve 10. The top of the top cover 14 is fixedly connected to the bottom of the support plate 3. The outer wall of the second hollow column 7 is slidably connected to the inner wall of the first hollow column 4. The inner wall of the second hollow column 7 is slidably connected to the outer wall of the third hollow column 9. The outer wall of the first threaded sleeve 10 is slidably connected to the inner wall of the third hollow column 9. The outer wall of the second threaded sleeve 11 is set on the inner wall of the first threaded sleeve 10. The inner wall of the first threaded sleeve 10 is set on the outer wall of the third threaded sleeve 13.

[0038] Working principle: When using the adjustable power transmission device for power engineering construction, first place the base 1 on the ground, and then support the entire device with the base 1 and the bracket 2. Next, the output end of the motor 5 drives the screw 6 to rotate. During the rotation of the screw 6, the first nut 8 on the outer wall moves. Next, the first nut 8 drives the second hollow column 7 to slide inside the first hollow column 4. Next, during the rotation of the first nut 8, the third threaded sleeve 13 on the outer wall rotates. Next, during the rotation of the third threaded sleeve 13, the second nut 12 on the outer wall rotates. Next, the rotation of the second nut 12 moves the third hollow column 9 on the outer wall. Next, during the rotation of the third hollow column 9, the first threaded sleeve 10 on the inner wall rotates, and then moves to the outer wall of the second threaded sleeve 11. Subsequently, the top cover 14 and the top support plate 3 move, thus achieving the effect of adjusting the height.

[0039] Next, when clamping the wire, first pull the handle 16. The handle 16 drives the fixing post 17 on the outer wall to slide on the inner wall of the hollow block 15. Then, as the fixing post 17 moves, it drives the clamping plate 19 at one end to move. Then, as the fixing post 17 moves, it will retract the spring 18 on the outer wall. Then, the spring 18 will return the clamping plate 19 to its original position through the rebound force of the spring 18, thus achieving the effect of adaptively clamping wires of different sizes.
