Description

Technical Field

[0001] This utility model relates to the field of power transmission technology, and in particular to an adjustable fixed support crossarm. Background Technology

[0002] The pole has multiple crossbars installed on it to support the overhead line. The overhead line can be buried in two ways: the cable bundle can be bent and guided to the pole and buried through the pole, or it can be buried vertically. Each of these methods has its drawbacks: bending the cable bundle can easily damage it, posing a safety hazard to the power transmission system; burying the cable bundle vertically from the cable platform requires a lot of installation space, and in some situations, this method is not suitable due to site constraints.

[0003] Therefore, how to adjust the direction of the cable bundle so that it can be led out at any angle to adapt to various installation scenarios has become a major challenge in the construction of power transmission systems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable fixed support crossarm so that the cable fixing support can adapt to the routing direction of the cable bundle.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an adjustable fixed support crossarm, including a crossarm body, one end of which is fixedly connected to a rod connecting seat, and the other end is connected to a cable fixing bracket. The cable fixing bracket is installed in the vertical direction and gradually tilts towards the rod from top to bottom. A plug is provided at one end of the crossarm body connected to the cable fixing bracket. A plug interface for accommodating the plug is provided in the middle of the cable fixing bracket. The plug is inserted into the plug interface. Mounting plates are provided on both sides of the plug interface. A connecting plate is installed at the end of the plug. The connecting plate is fixedly installed on the mounting plates on both sides of the plug interface by bolts and nuts. A cable bundle extends downward along the cable fixing bracket. The surface of the cable fixing bracket is provided with support bars for supporting the cable bundle. The cable bundle is installed on the support bars by cable fasteners.

[0006] As a preferred technical solution, the cable fixing component is a cable clamp or a cable pressure plate.

[0007] As a preferred technical solution, the cable fixing bracket includes two parallel longitudinal beams, and the support bars are installed between the longitudinal beams. The number of support bars is multiple and they are arranged in parallel on the longitudinal beams.

[0008] As a further improvement, the cross-sectional shape of the connector is square, and the shape of the connector on the cable fixing bracket is rectangular to match the shape of the connector in its inclined state. The middle position of the cable fixing bracket is also provided with a connector adjustment device for adjusting the longitudinal length of the connector. The connector adjustment device includes two parallel support beams. The width between the two support beams is adapted to the width of the connector of the crossarm body. Two crossbars are slidably installed between the two support beams. The two crossbars are symmetrically arranged and slide in opposite directions. The two crossbars slide in opposite directions to adjust the longitudinal length of the connector.

[0009] As a further improvement, each crossbar is provided with a fixed rod on its outer side, which is also installed between two support beams. A sliding screw extending to the fixed rod is fixedly connected to the side of the crossbar. The outer wall of the sliding screw is provided with external threads. The end of the sliding screw passes through the fixed rod and is equipped with an adjusting nut. A spring is provided between the crossbar and the fixed rod, and the spring is sleeved on the outside of the sliding screw.

[0010] As another improvement, a positioning bolt is also installed between the crossbar and the fixed rod. The end of the positioning bolt passes through the crossbar and the fixed rod in sequence. The end of the positioning bolt is fixed to the fixed rod by a first set nut and a second set nut. The first set nut and the second set nut are symmetrically installed on both sides of the fixed rod or the crossbar.

[0011] As a preferred technical solution, the crossbar is an "L"-shaped angle steel, which includes two vertically arranged first side plates and second side plates. The first side plate abuts against the plug of the rod body and its surface is parallel to the support surface of the cable fixing bracket. The second side plate is perpendicular to the support surface of the cable fixing bracket, and the sliding screw is installed on the second side plate.

[0012] As an improvement, two sliding screws are installed between each crossbar and the fixed bar, the sliding screws are symmetrically arranged, and the positioning bolt is located between the two sliding screws.

[0013] As another improvement, the inner side of the support beam is bent toward the insertion interface to form a support platform, the fixing rod is fixedly installed on the support platform, and the crossbar slides along the support platform.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are: By setting inclined cable fixing brackets at the ends of the crossarm body, the cable bundle can extend downwards or into the ground at any angle. The cable bundle is constrained on the cable fixing brackets, which can prevent it from shifting, sagging, vibrating, or rubbing against each other, and can maintain the neat arrangement and separation of the cables.

[0015] Because the inclination angle of the crossarm connector can be adjusted to adapt to the cable route, the inclination angle of the cable fixing bracket can be flexibly set, the cable bundle installation is reliable and convenient, and it can adapt to the installation of cable bundles of different sizes, as well as the needs of moving the installation position of the cable bundle or future line changes.

[0016] Cable bundles are installed using cable fasteners (such as clamps and pressure plates), and have a wide range of adjustment to accommodate cable bundles of different diameters and quantities.

[0017] Because the cable fixing bracket's connector can be adjusted according to the tilt angle, the cable fixing bracket can be used for installations with various tilt angles. Attached Figure Description

Detailed Implementation

[0021] like Figures 1 to 4 As shown, an adjustable fixed support crossarm includes a crossarm body 100, one end of which is fixedly connected to a pole connecting seat 101, and the crossarm body 100 is fixedly connected to the pole body through the pole connecting seat 101.

[0022] The other end of the crossarm body 100 is connected to a cable fixing bracket 200. In order to follow the direction of the cable routing, the cable fixing bracket 200 is installed vertically and gradually tilts towards the pole from top to bottom. One end of the crossarm body 100 connected to the cable fixing bracket 200 is provided with a plug connector 102. The middle of the cable fixing bracket 200 is provided with a plug interface 201 to accommodate the plug connector 102. The plug connector 102 is inserted into the plug interface 201. Mounting plates 202 are provided on both sides of the plug interface 201. A connecting plate (not shown in the figure) is installed at the end of the plug connector 102. The connecting plate is fixedly installed on the mounting plates 202 on both sides of the plug interface 201 by bolts and nuts.

[0023] The cable bundle 500 extends downward along the cable fixing bracket 200. The surface of the cable fixing bracket 200 is provided with support bars 210 for supporting the cable bundle 500. The cable bundle 500 is mounted on the support bars 210 by cable fasteners (see details). Figure 4 (The dotted line portion) Preferably, the cable fastener is a cable clamp 400 or a cable pressure plate.

[0024] The cable fixing bracket 200 includes two parallel longitudinal beams 220, and support bars 210 are installed between the longitudinal beams 220. There are multiple support bars 210, which are arranged in parallel on the longitudinal beams 220.

[0025] Because the cable fixing bracket 200 has different inclination angles, the cross-sectional area of ​​the connector 102 of the crossarm body 100 inserted into the cable fixing bracket 200 will increase with the increase of the inclination angle. Specifically, the width direction remains constant, while the length direction changes according to the inclination angle. Figure 1 In the process, the length a of the plug 102 changes with the tilt angle, the cross-sectional shape of the plug 102 is rectangular, and the shape of the insertion interface 201 on the cable fixing bracket 200 is also rectangular to match the shape of the plug 102, that is, to match the cross-sectional shape of the plug 102 inserted into the insertion interface 201.

[0026] To adapt the size of the connector 201 to the tilt angle, a connector adjustment device for adjusting the longitudinal length of the connector 201 is provided in the middle of the fixed bracket. The connector adjustment device includes two parallel support beams 310. The width between the two support beams 310 is adapted to the width of the connector 102 of the crossbeam body 100. Two crossbars 320 are slidably installed between the two support beams 310. The two crossbars 320 are symmetrically arranged and slide in opposite directions. The two crossbars 320 slide in opposite directions to adjust the longitudinal length of the connector 201.

[0027] Each crossbar 320 has a fixed rod 330 on its outer side, which is also installed between the two support beams 310. A sliding screw 340 extending to the fixed rod 330 is fixedly connected to the side of the crossbar 320. The outer wall of the sliding screw 340 is provided with external threads. The end of the sliding screw 340 passes through the fixed rod 330 and is equipped with an adjusting nut 342. A spring 341 is provided between the crossbar 320 and the fixed rod 330. The spring 341 is sleeved on the outside of the sliding screw 340. Pushing the crossbar 320 pushes the sliding screw 340 out to one side of the fixed rod 330. Rotating the adjusting nut 342 adjusts the length of the sliding screw 340 extending out of the fixed rod 330, thereby adjusting the length of the insertion interface 201.

[0028] A positioning bolt 350 is also installed between the crossbar 320 and the fixed rod 330. The end of the positioning bolt 350 passes through the crossbar 320 and the fixed rod 330 in sequence. The end of the positioning bolt 350 is fixed to the fixed rod 330 by the first set nut 351 and the second set nut 352. The first set nut 351 and the second set nut 352 are symmetrically installed on both sides of the side wall of the fixed rod 330. By fixing the positioning bolt to the fixed rod 330 by the first set nut 351 and the second set nut 352, the crossbar 320 is also locked and cannot move.

[0029] The crossbar 320 is an "L"-shaped angle steel. The "L"-shaped angle steel includes two vertically arranged first side plates and second side plates. The first side plate abuts against the plug 102 of the bar body and its surface is parallel to the support surface of the cable fixing bracket 200 for installing the cable bundle. The first side plate abuts against the plug 102 so that the plug 102 can be inserted into the plug interface 201. The second side plate is perpendicular to the support surface of the cable fixing bracket 200 so that the sliding screw 340 can be installed on the second side plate.

[0030] To ensure adjustment accuracy and prevent tilting due to uneven adjustment length of the connector 201, two sliding screws 340 are installed between each crossbar 320 and the fixed rod 330. The sliding screws 340 are symmetrically arranged, and the positioning bolt 350 is located between the two sliding screws 340.

[0031] To facilitate guidance and support, the inner side of the support beam 310 is bent toward the insertion interface 201 to form a support platform 311. The fixing rod 330 is fixedly installed on the support platform 311, and the crossbar 320 slides along the support platform 311.

[0032] In use, the following steps are taken: First, determine the inclination angle of the cable fixing bracket 200. Then, process the top of the connector 102 of the crossarm body 100 into a cross section that matches the inclination angle of the cable fixing bracket 200. Insert the connector 102 into the insertion interface 201. Push the crossbar 320 to both sides, causing the first side plate of the crossbar 320 to abut against the connector 102. The end of the sliding screw 340 is then pushed out of the fixing rod 330 by a certain length. Rotate the adjusting nut 342 to determine the length by which the sliding screw 340 extends beyond the fixing rod 330. Finally, the positioning bolt 35... The first set nut 351 and the second set nut 352 on both sides of the side wall of the fixed rod 330 lock the distance between the fixed rod 330 and the crossbar 320, thus completing the size adjustment of the insertion interface 201. The insertion direction of the positioning bolt 350 can also be reversed. The positioning bolt 350 first passes out from one side of the fixed rod 330 and then passes through the crossbar 320. The first set nut 351 and the second set nut 352 are installed on both sides of the first side plate of the crossbar 320, which can be flexibly adjusted according to the installation space on site.

[0033] The connecting plate at the top of the connector 102 is fixedly installed on the mounting plates 202 on both sides of the connector 201 by bolts and nuts, thus completing the assembly of the crossarm body 100.

[0034] When installing the cable bundle 500, the cable bundle 500 is routed along the cable fixing bracket 200 and installed on the support bar 210 through the cable clamp 400.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
