Description

Technical Field

[0001] This utility model relates to the field of power cable technology, and in particular to a power cable support. Background Technology

[0002] During temporary power supply at the construction site, cables are required to be overhead to prevent them from dragging on the ground and causing electric shock accidents. When overhead cables are used, cable overhead supports must be used.

[0003] In the prior art, Chinese patent application number 202421415877.2 discloses an overhead power cable support, including a counterweight base. A support frame is fixedly connected to the top of the counterweight base via a mounting bracket, and the bottom of the support frame is spaced apart from the top of the counterweight base. A slide block is slidably connected to the inner wall of the support frame via a sliding groove. In this application, the slide block is moved to a suitable height by connecting the outer sleeve of the slide block to the sliding groove at the bottom of the support frame. Rotating the positioning rod causes it to engage with the inner wall of the mounting plate, while the open end of the positioning rod abuts against the outer wall of the support frame. Through friction, the placement sleeve and slide block are fixed together, and the cable is attached to the inside of the placement sleeve. The pressure sleeve is then flipped to engage with the fixing sleeve, and a locking rod secures the pressure sleeve and fixing sleeve together, thus achieving cable overhead support. This process is repeated, allowing for the increase or decrease of the number of placement sleeves according to usage requirements, while each set of placement sleeves can be independently adjusted in height.

[0004] However, the above technical solutions have the drawbacks that although the spacing between the various placement sleeves can be adjusted, the height of the support frame is fixed, making it impossible to adjust the overall height of the cables on multiple placement sleeves, resulting in poor applicability. Furthermore, fixing the position of the bracket requires rotating multiple reinforcing rods in sequence, which is time-consuming and laborious, and cannot meet the usage requirements. Therefore, this application proposes a power cable bracket to solve the above problems. Utility Model Content

[0017] Example Reference Figures 1-4 A power cable support includes a counterweight base 1, with four rollers 2 mounted on the bottom of the counterweight base 1. The cable support also includes: The bottom end of the first support frame 3 is fixedly installed on the top of the counterweight base 1; The bottom end of the second support frame 4 is slidably sleeved on the top end of the first support frame 3; The lifting assembly includes: a lead screw 9, a lifting rod 10, a worm gear 12, a rotating shaft 13, and a worm 14. The top and bottom ends of the lead screw 9 are rotatably connected to the top inner wall and bottom inner wall of the first support frame 3, respectively. The lifting rod 10 is threaded onto the lead screw 9. The left and right ends of the lifting rod 10 pass through the inner wall of the first support frame 3 and extend to the outside of the first support frame 3, respectively. The top of the lifting rod 10 is fixedly installed at the bottom of the second support frame 4. The worm gear 12 is fixedly sleeved on the lead screw 9. The left end of the rotating shaft 13 passes through the first support frame 3 and is rotatably connected to the inner wall of the first support frame 3. The worm 14 is fixedly sleeved on the rotating shaft 13 and meshes with the worm gear 12. The placement component is mounted on the second support frame 4 and is used to support and fix the cable. The positioning component is mounted on the counterweight base 1 and is used to fix the position of the power cable bracket.

[0018] To address the issue of inconvenient height adjustment of cables on multiple placement sleeves 7, such as... Figure 1 As shown, rotating the shaft 13 can drive the worm gear 14 to rotate. Then, through the meshing transmission between the worm gear 14 and the worm wheel 12, the lead screw 9 can be driven to rotate. Then, through the threaded connection between the lead screw 9 and the lifting rod 10, the lifting rod 10 and the second support frame 4 can be adjusted in height. This allows for overall height adjustment of the second support frame 4 and the multiple placement sleeves 7 on it. It can be adjusted according to the overall support height of multiple cables, making it highly adaptable.

[0019] To facilitate the rotation of the shaft 13, a handle 15 is fixedly installed on the right end of the shaft 13.

[0020] In order to facilitate the lifting and lowering movement of the lifting rod 10 and to provide stable sliding support for the lifting rod 10, sliding holes 11 are provided on the left and right inner walls of the first support frame 3. The left and right ends of the lifting rod 10 pass through the two sliding holes 11 respectively and are slidably connected to the inner walls of the sliding holes 11.

[0021] To assist the upward movement of the second support frame 4, a spring 8 is fixedly installed at the top of the first support frame 3, and the top of the spring 8 is fixedly installed on the inner top wall of the second support frame 4.

[0022] To achieve stable support and placement of the cable, the placement assembly includes multiple slides 6 and multiple placement sleeves 7. The second support frame 4 has grooves 5 on both the left and right sides. The slides 6 are slidably connected in the corresponding grooves 5, and one side of the placement sleeve 7 is fixedly installed on one side of the corresponding slide 6.

[0023] To fix the position of the cable bracket, when the cable bracket is moved to the usage position, rotating any one of the turntables 19 will drive the corresponding screw 18 to rotate. At this time, through the transmission wheel 20 and the transmission belt 21, the two screws 18 can be driven to rotate synchronously in the same direction. Then, through the threaded connection between the screw 18 and the moving frame 16, the moving frame 16 and the two positioning rods 17 can be moved up and down. When the two positioning rods 17 move down, they can contact the ground and achieve stable positioning of the cable bracket. To ensure the stability of the cable bracket during use, the positioning assembly includes a movable frame 16, two positioning rods 17, two screws 18, and two turntables 19. The movable frame 16 is sleeved on the first support frame 3. The top ends of the two positioning rods 17 are fixedly installed at the bottom of the movable frame 16, and the bottom ends of the two positioning rods 17 penetrate through the counterweight base 1 and are slidably connected to the counterweight base 1. The bottom ends of the two screws 18 penetrate through the movable frame 16 and are rotatably connected to the top of the counterweight base 1. The two screws 18 are threadedly connected to the movable frame 16, and the turntables 19 are fixedly installed at the top ends of the corresponding screws 18.

[0024] In order to achieve synchronous rotation of the two screws 18, a transmission wheel 20 is fixedly installed at the bottom end of each screw 18, and the same transmission belt 21 is fitted on the two transmission wheels 20.

[0025] It should be noted that the second support frame 4, the slide 5, the slide seat 6 and the placement sleeve 7 adopt existing technology and can be directly used with the structure of the patent with application number 202421415877.2, so they will not be described in detail.

[0026] The working principle of this utility model is as follows: In use, rotating the shaft 13 first drives the worm gear 14 to rotate. Through the meshing transmission between the worm gear 14 and the worm wheel 12, the lead screw 9 rotates. Then, through the threaded connection between the lead screw 9 and the lifting rod 10, the lifting rod 10 and the second support frame 4 can be adjusted in height, thereby allowing for overall height adjustment of the second support frame 4 and its multiple placement sleeves 7. This allows for adjustment based on the overall support height of multiple cables, making it highly adaptable. Furthermore, when the cable bracket is moved to its operating position, rotating any turntable 19 drives the corresponding screw 18 to rotate. Through the transmission wheel 20 and the transmission belt 21, the two screws 18 rotate synchronously in the same direction. Then, through the threaded connection between the screw 18 and the moving frame 16, the moving frame 16 and the two positioning rods 17 can move up and down. When the two positioning rods 17 move down, they contact the ground and achieve stable positioning of the cable bracket, ensuring its stability during use.
