Description

Technical Field

[0001] This utility model relates to the field of cable crossing transfer racks, and more particularly to a foldable cable crossing transfer rack. Background Technology

[0002] Crossing a power line refers to the power transmission operation that crosses a lower power line from one side to the other. The transfer frame is activated by a hydraulic device and opens its "ribs" like an umbrella. When erecting a new line, it can support the cable and achieve uninterrupted power transmission across 35 kV and below lines. When crossing highways, it can also be done without closing the road, effectively improving the safety and efficiency of crossing construction.

[0003] Existing cable crossing transfer frames are generally designed to be foldable to facilitate easy relocation during construction, thereby reducing their footprint and simplifying the process. However, the folded area of ​​existing transfer frames is fixed during cable installation. When supporting large areas of cables, multiple transfer frames need to be spliced ​​together, making the adjustment and installation process cumbersome and complex, resulting in inconvenience and increasing the difficulty and cost of use. Therefore, a foldable cable crossing transfer frame is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 One embodiment of this utility model is a foldable cable crossing transfer frame, including a crossbeam 1, a top plate 2 fixedly connected to the top of the crossbeam 1, load-bearing plates 3 hinged to the left and right sides of the crossbeam 1, a load-bearing block 4 with a rectangular cross section fixedly connected to the top of the load-bearing plate 3, and a protective mechanism 10 provided on the top of the load-bearing plate 3.

[0031] Reference Figures 1-3 The protective mechanism 10 includes a frame 5 in the shape of a square frame. The frame 5 is hinged to the side of the load-bearing plate 3 away from the crossbeam 1. A vertical reinforcing plate 6 is fixedly connected to the inner wall of the frame 5. A horizontal round rod 7 is fixedly connected to the inner wall of the reinforcing plate 6. The angle between the round rod 7 and the reinforcing plate 6 is 90 degrees. A gap is formed between the reinforcing plate 6 and the round rod 7, which can reduce the overall weight of the frame 5 while increasing the working area that can support the cable. The left and right ends of the round rod 7 are fixedly connected to the inner wall of the frame 5. A groove 8 is provided on the top of the load-bearing plate 3. The groove 8 is used to accommodate the reinforcing plate 6 and the round rod 7.

[0032] Reference Figure 2 , Figure 3The frame 5 is connected to the load-bearing plate 3 via a fixing mechanism 11. The fixing mechanism 11 includes a circular plate 12, which is fixedly connected to the front and rear sides of the load-bearing plate 3. The circular plate 12 is fixedly connected to the frame 5 via bolts 13. The surface of the circular plate 12 is provided with multiple through holes 14, which are arranged in a ring at equal angles on the surface of the circular plate 12. The bolts 13 pass through the inside of the through holes 14. By inserting the bolts 13 into the through holes 14 at different positions, the load-bearing plate 3 and the frame 5 can be fixed at different angles. A support mechanism 15 is provided at the bottom of the crossbeam 1.

[0033] Reference Figure 1 The support mechanism 15 includes a support column 16, which is fixedly connected to the bottom of the crossbeam 1. A support base plate 17 is fixedly connected to the bottom of the support column 16. The top of the support base plate 17 is provided with reinforcing ribs to improve the stability of the support base plate 17 and the support column 16. Multiple ground nails 18 are provided on the surface of the support base plate 17 to firmly fix the support column 16 to the ground and provide a good construction environment.

[0034] Reference Figure 1 , Figure 4 The support mechanism 15 also includes a stepper motor 19. The stepper motor 19 has high control precision and is fixedly connected inside the support column 16. A screw 20 is fixedly connected to the top of the output shaft of the stepper motor 19. A moving block 21 is sleeved on the surface of the screw 20 and is slidably connected to the inner wall of the support column 16. When the stepper motor 19 rotates, the moving block 21 is linearly displaced in the axial direction of the screw 20. The support mechanism 15 also includes a connecting rod 22 that is set in an inclined state. One end of the connecting rod 22 is hinged to the surface of the moving block 21, and the other end of the connecting rod 22 is hinged to the bottom of the load-bearing plate 3. The unfolding angle of the load-bearing plate 3 relative to the crossbeam 1 is precisely controlled by controlling the rotation angle of the output shaft of the stepper motor 19.

[0035] Working principle: When in use, the crossbeam 1 is fixed to the working area by the support mechanism 15, and the ground nails 18 at the bottom of the support column 16 are inserted into the ground, so that the support column 16 is vertically and stably fixed on the ground. The stepper motor 19 is started by the controller, which drives the screw 20 to rotate, thereby driving the moving block 21 to rise and fall vertically along the inner wall of the support column 16. The moving block 21 pushes the load-bearing plate 3 to unfold around the hinge point of the crossbeam 1 through the connecting rod 22, forming a large-area working platform.

[0036] After the load-bearing plate 3 is unfolded into place, the frame 5 is rotated out from the inside of the groove 8 and fastened to the circular plate 12 by bolts 13, thereby fixing the frame 5 and the load-bearing plate 3 tightly together so that the frame 5 will not loosen or fall off due to external force. By passing the bolts 13 through the through holes 14 at different positions on the circular plate 12, the frame 5 and the load-bearing plate 3 can be fixed at different angles. With the support of the load-bearing plate 3 and the protective mechanism 10, the cable can be transferred across the space above the top plate 2. The stepper motor 19 can finely adjust the screw 20 to tilt the load-bearing plate 3 at a certain angle to adapt to cable paths with different slopes.

[0037] After the transfer operation across the line is completed, the reinforcing plate 6 and the round rod 7 of the frame 5 are stored in the groove 8, and the bolts 13 are inserted into the corresponding through holes 14 to fix the load-bearing plate 3 and the frame 5. Then, the stepper motor 19 is driven in reverse to fold the load-bearing plate 3, so that the overall equipment is reduced in size after folding, making it easier to transport and transfer.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
