[0023] 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.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A power line laying frame for electrical construction includes:

[0026] The frame includes a base plate 1, a support column 11 fixedly connected to the surface of the base plate 1, a placement platform 12 fixedly connected to the surface of the support column 11, a locking block 13 provided on the surface of the placement platform 12, and a placement rod 14 connected to the inner side of the locking block 13. With the connection between the base plate 1 and the support column 11, and the connection between the support column 11 and the placement platform 12, the support effect of the locking block 13 is achieved. There are two sets of locking blocks 13, and the two sets of locking blocks 13 are connected by bolts. Under the action of the locking block 13, the placement rod 14, in conjunction with the use of bearings, fixes the position of the placement rod 14, and the placement rod 14 can rotate.

[0027] The braking mechanism includes a brake disc 2, which is sleeved on the surface of a placement rod 14. A connecting sleeve 21 is fixedly connected to the surface of the brake disc 2, and a stop rod 22 is connected through the surface of the connecting sleeve 21. A support frame 23 is fixedly connected to the surface of the placement platform 12, and a stop block 24 is fixedly connected to the surface of the support frame 23. A handle 25 is movably connected to the surface of the support frame 23, and a brake pad 26 is fixedly connected to the surface of the handle 25. Through the connection between the brake disc 2 and the connecting sleeve 21, and the connection between the connecting sleeve 21 and the stop rod 22, the brake disc 2's position on the placement rod 14 is limited and supported. Through the action of the stop block 24 and the brake pad 26, the angle of the handle 25 is changed, causing the brake pad 26 to abut against the surface of the brake disc 2, thereby achieving the braking control effect on the rotation of the placement rod 14.

[0028] Furthermore, the brake disc 2 is connected to the placement rod 14 via the connecting sleeve 21 and the abutment rod 22. The abutment rod 22 is connected in two opposing sets on both sides of the connecting sleeve 21. The abutment block 24 and the brake pad 26 are distributed on both sides of the brake disc 2. Through the connection of the abutment rod 22 and the connecting sleeve 21, the abutment rod 22 and the placement rod 14 make contact, thereby achieving the effect of limiting the position of the brake disc 2 on the placement rod 14.

[0029] Furthermore, the support frame 23 is L-shaped, the abutment 24 is distributed on one side of the brake disc 2 via the support frame 23, and the brake pad 26 is distributed on the other side of the brake disc 2 via the handle 25. Through the connection between the support frame 23 and the abutment 24, the position of the abutment 24 is fixed under the action of the support frame 23. Through the connection between the handle 25 and the brake pad 26, the position of the brake pad 26 can be easily adjusted under the rotational connection between the handle 25 and the support frame 23, so as to achieve contact between the brake pad 26 and the surface of the brake disc 2, and realize the braking operation of the rotating rod 14.

[0030] Furthermore, a limiting mechanism is provided on the surface of the locking block 13. The limiting mechanism includes a guide plate 3 and a support rod 31. The support rod 31 is rotatably connected to the locking block 13 via a movable seat. The guide plate 3 and the support rod 31 are fixedly connected. A moving groove 32 is opened on the surface of the guide plate 3. A limiting groove 33 is opened on the inner side of the moving groove 32. A limiting block 34 is slidably connected to the inner side of the limiting groove 33. A support block 35 is fixedly connected to the surface of the limiting block 34. A limiting plate 310 is fixedly connected to the inner side of the support block 35. A telescopic rod 38 is passed through the surface of the limiting plate 310. A movable plate 36 is fixedly connected to the surface of the telescopic rod 38. A rotating ball 37 is movably connected to the inner side of the movable plate 36. A support spring 39 is sleeved on the outer surface of the telescopic rod 38. Through the connection between the locking block 13 and the movable seat, and under the bolt connection between the movable seat and the support rod 31, the connection angle of the support rod 31 on the locking block 13 is changed by rotating the bolt, thereby changing the working position of the guide plate 3.

[0031] Furthermore, the guide plate 3 acts above the placement rod 14 through the support rod 31 and the locking block 13. The limiting grooves 33 are arranged in two opposing sets on both sides of the moving groove 32. The support block 35 is slidably connected to the moving groove 32 through the limiting block 34 and the limiting groove 33. Through the connection between the guide plate 3 and the moving groove 32, and the connection between the moving groove 32 and the limiting groove 33, the sliding connection between the limiting groove 33 and the limiting block 34 facilitates the adjustment of the position of the support block 35 and the movable plate 36 on the guide plate 3.

[0032] Furthermore, the movable plates 36 are distributed in two groups on both sides of the support block 35. The support block 35 and the movable plates 36 form a ring. The rotating balls 37 are evenly distributed on the inner surface of the movable plates 36. Through the connection between the movable plates 36 and the rotating balls 37, the contact friction between the movable plates 36 and the cable is reduced under the action of the rotating balls 37, thus avoiding wear.

[0033] Furthermore, the movable plate 36 and the support block 35 are connected by the telescopic rod 38 and the limiting plate 310. The two ends of the support spring 39 are fixedly connected to the surfaces of the limiting plate 310 and the movable plate 36. The movable plate 36 and the support block 35 are elastically connected by the support spring 39. With the telescopic rod 38 and the limiting plate 310 penetrating the connection, the elastic connection between the movable plate 36 and the support block 35 is achieved through the action of the support spring 39, changing the functional dimensions of the movable plate 36 and the support block 35, which facilitates the guidance of cables of different specifications.

[0034] Working principle: When braking the rotation of the placement rod 14, pulling the handle 25 changes the connection angle of the handle 25 on the support frame 23. At this time, the brake pad 26 and the brake disc 2 abut against each other. Under the action of the friction of their contact, the placement rod 14 stops rotating. Under the abutment contact of the abutment rod 22 and the placement rod 14, the brake disc 2 is supported at its position on the placement rod 14, and it is convenient to disassemble and assemble it. With the connection of the guide plate 3 and the moving groove 32, the support block 35 and the movable plate 36 facilitate the guidance of the cable during cable laying. With the connection of the movable plate 36 and the telescopic rod 38, the telescopic rod 38 and the limiting plate 310 are connected through the support spring 39, so that the movable plate 36 and the support block 35 slide elastically, changing the functional size of the movable plate 36 and the support block 35, which facilitates the guidance of cables of different specifications.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
