Description

Technical Field

[0001] This utility model relates to the field of cable assembly technology, specifically to a cable support frame for power transmission and distribution. Background Technology

[0002] A cable is a wire consisting of one or more mutually insulated conductors covered by an outer insulating protective layer. It is used to transmit electrical energy or electrical signals. It includes conductors, insulation layers, shielding layers, and sheathing layers, which respectively perform the functions of conducting electricity, insulating, shielding interference, and protecting against the external environment. It is then classified in various ways according to voltage level, insulation materials, etc. It is the key to power transmission and distribution systems.

[0003] In existing technologies, the conventional procedure for using cable support frames is to first accurately place the support frame in the planned assembly position, and then place the cable stably on top of the support frame to achieve the basic support function for the cable. However, if the cable length is misestimated or the site layout is temporarily adjusted, it is often necessary to pull the installed cable. This causes the strong force generated by the external force pulling the cable to be transmitted to the support frame along the contact point, making it difficult for the support frame to withstand the huge lateral tension. Ultimately, this causes the entire support frame to tilt or even fall over. Once the support frame falls over, it will not only cause the cable to move out of its normal installation position and cause local line disorder, but more seriously, it may cause a series of safety accidents such as cable insulation damage and short circuits, which will greatly threaten the stable operation of the power transmission and distribution system and bring great difficulties to power emergency repair and maintenance work. To address this, we propose a cable support frame for power transmission and distribution. Utility Model Content

[0004] The purpose of this utility model is to provide a cable support frame for power transmission and distribution to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power transmission and distribution cable support frame, comprising a support frame, a lifting assembly fixedly connected inside the support frame, a placement block installed on the top of the lifting assembly, multiple placement slots opened inside the support frame, a support wheel rotatably connected inside the placement slots, an installation plate fixedly connected inside the placement block, two mounting plates fixedly connected to the top of the installation plate, two rotating slots opened inside the placement block, telescopic rods fixedly connected to the four corners of the top, springs sleeved on the outside of the telescopic rods, a fixing plate fixedly connected to the top of every two telescopic rods, a connecting shaft fixedly connected inside every two fixing plates, and a support wheel rotatably connected to the outside of the connecting shaft.

[0006] The bracket frame is fixedly connected to multiple warning signs and multiple reflective signs.

[0007] The lifting assembly has a hollow column fixedly connected to the top, a top column slidably connected inside the hollow column, a sliding groove inside the hollow column, two sliders fixedly connected to the outside of the top column, a threaded rod rotatably connected inside the hollow column, a rotating ring fixedly connected to the outside of the threaded rod, a threaded block threadedly connected to the outside of the threaded rod, a connecting plate rotatably connected to the top of the threaded block, a connecting block rotatably connected to the outside of the connecting plate, a limit block fixedly connected to the bottom of the threaded block, and a limit groove on the outside of the lifting assembly.

[0008] The lifting assembly is fixedly connected to a support column at the top, and a support ring is fixedly connected to the top of the support column.

[0009] The connecting block is externally fixed to the outside of the top column, and the limiting block is externally slidably connected to the inside of the limiting groove.

[0010] The limiting block is externally slidably connected to the inside of the lifting assembly, and the slider is externally slidably connected to the inside of the slide groove.

[0011] One side of the spring is fixedly connected to the bottom of the fixing block, and the other side of the spring is fixedly connected to the bottom of the fixing plate.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, this utility model allows for cable support by placing the support frame at the assembly location, inserting the cable into the placement block, and first contacting the first support wheel before pressing down on the second support wheel to increase the contact area. When pulling the cable, because the cable does not directly contact the support frame, it prevents the support frame from tipping over due to cable tension, avoiding cable detachment, line malfunction, insulation damage, short circuits, and other safety accidents, thus ensuring the stability of the power transmission and distribution system. Rotating the rotating ring drives the threaded rod to rotate, which, through the threaded block and connecting plate, lifts the placement block to a suitable height, allowing for flexible height adjustment and improved applicability. Furthermore, the warning sign on the support frame serves as a warning, and the reflective sign enhances protection at night, alerting surrounding personnel and reducing accidents, thereby lowering the safety risks and difficulties in power emergency repairs and maintenance.

[0019] 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.

[0020] Example 1

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a cable support frame for power transmission and distribution, including a support frame 1, a lifting assembly 2 fixedly connected inside the support frame 1, a placement block 4 mounted on the top of the lifting assembly 2, multiple placement slots 401 opened inside the support frame 1, a support wheel 402 rotatably connected inside the placement slots 401, an installation plate 403 fixedly connected inside the placement block 4, two fixing blocks 404 fixedly connected to the top of the installation plate 403, two rotating slots 405 opened inside the placement block 4, telescopic rods 406 fixedly connected to the four corners of the top of the fixing blocks 404, springs 407 sleeved on the outside of the telescopic rods 406, one side of the springs 407 fixedly connected to the bottom of the fixing blocks 404, the other side of the springs 407 fixedly connected to the bottom of the fixing plates 408, a fixing plate 408 fixedly connected to the top of every two telescopic rods 406, and a connecting shaft 409 fixedly connected inside every two fixing plates 408. A second support wheel 4010 is rotatably connected to the outside of the connecting shaft 409. When supporting the cable, the bracket frame 1 is placed at the assembly location, and then the cable is placed inside the placement block 4. At this time, the cable will contact the outside of the first support wheel 402 and the second support wheel 4010. Due to the weight of the cable, the second support wheel 4010 will be squeezed downwards, which, together with the telescopic rod 406, presses down and compresses the spring 407. The contact area between the cable and the first support wheel 402 and the second support wheel 4010 increases, improving the stability of the support. When the cable is pulled, the cable will not directly contact the placement block 4, but will slide on the first support wheel 402 and the second support wheel 4010. The rotation of the first support wheel 402 and the second support wheel 4010 reduces the friction between the cable and the placement block 4, so that the placement block 4 will not tilt when the cable is pulled, and the cable can be pulled smoothly.

[0022] Multiple warning signs 101 and multiple reflective signs 102 are fixedly connected to the outside of the support frame 1. The warning signs 101 are fixed to the outside of the support frame 1 to issue warning signals to people in the surrounding area, reminding them to pay attention to the cable support frame and related cable equipment to avoid accidents. The reflective signs 102 can reflect light at night or in low light conditions, improve the visibility of the cable support frame, enhance safety when using it at night, and play a protective role.

[0023] A hollow column 201 is fixedly connected to the top of the lifting assembly 2. A top column 202 is slidably connected inside the hollow column 201. A sliding groove 203 is opened inside the hollow column 201. Two sliders 204 are fixedly connected to the outside of the top column 202. A threaded rod 205 is rotatably connected inside the hollow column 201. A rotating ring 206 is fixedly connected to the outside of the threaded rod 205. A threaded block 207 is threadedly connected to the outside of the threaded rod 205. A connecting plate 208 is rotatably connected to the top of the threaded block 207. A connecting block 209 is rotatably connected to the outside of the connecting plate 208. The connecting block 209 is fixedly connected to the outside of the top column 202. A limiting block 2010 is slidably connected to the inside of the limiting groove 2011. The bottom of the threaded block 207... A limiting block 2010 is fixedly connected to the lifting assembly 2. The limiting block 2010 is externally slidably connected to the inside of the lifting assembly 2. The slider 204 is externally slidably connected to the inside of the slide groove 203. A limiting groove 2011 is opened on the outside of the lifting assembly 2. The threaded block 207 will move axially along the threaded rod 205 and approach the hollow column 201. As the threaded block 207 moves, the angle between the connecting plate 208 and the threaded block 207 gradually becomes perpendicular. The connecting plate 208 pushes the connecting block 209 and the top column 202 to move upward. With the cooperation of the slider 204 and the slide groove 203, the top column 202 rises smoothly in the hollow column 201, thereby driving the placement block 4 to rise, so that the placement block 4 and the top cable reach the appropriate height.

[0024] The top of the lifting assembly 2 is fixedly connected to a support column 3, and the top of the support column 3 is fixedly connected to a support ring 301; the support column 3 serves to fix the support ring 301 and provides an additional support point for the cable.

[0025] The working principle of this utility model is as follows: When supporting the cable, simply place the bracket frame 1 at the assembly location, and then place the cable inside the placement block 4 to complete the support of the cable. At this time, the cable placed inside the placement block 4 will contact the outside of the first support wheel 402 and the second support wheel 4010, and then squeeze the second support wheel 4010 downward, so that the second support wheel 4010 cooperates with the telescopic rod 406 to press down, so that the contact area between the cable and the first support wheel 402 and the second support wheel 4010 is larger. Then, the cable is pulled. The cable will not directly contact the placement block 4, so that the pulled cable will not cause the placement block 4 to tilt. At the same time, through the cooperation of the first support wheel 402 and the second support wheel 4010, the cable can slide effectively on the top of the placement block 4, so that the cable can be effectively pulled.

[0026] The warning sign 101 is used to enhance the warning effect, and the reflective sign 102 is used to enhance protection during nighttime use.

[0027] Example 2

[0028] Please see Figure 1 and Figure 4 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that when the height of the placement block 4 needs to be adjusted, it is only necessary to hold the rotating ring 206, so that the rotating ring 206 drives the threaded rod 205 to rotate. Then, the threaded block 207 outside the threaded rod 205 is limited by the limiting block 2010, so that the threaded block 207 drives the connecting plate 208 to move closer to the hollow column 201. Then, the angle between the threaded block 207 and the connecting plate 208 gradually becomes perpendicular. Then, the connecting plate 208 pushes the connecting block 209 and the top column 202 upward, so that the top column 202 drives the placement block 4 to rise, so that the placement block 4 and the top cable reach the appropriate height.
