Description

Technical Field

[0001] This utility model relates to the field of power tower technology, and more specifically, to an assembled crossarm structure applied to power towers. Background Technology

[0002] The towers of overhead power transmission lines are supporting structures used to support conductors and lightning protection wires. They ensure that the conductors meet the distance requirements to the ground and ground objects, and can withstand the loads of the conductors, lightning protection wires, and themselves, as well as external loads. Power towers are generally classified into five types according to their shape: goblet type, cat head type, U-shaped type, T-shaped type, and barrel type. According to their purpose, they are classified into tension towers, straight-line towers, angle towers, transposition towers (towers for changing conductor phase positions), terminal towers, and crossing towers, etc. Their structural characteristic is that all tower types are spatial truss structures, and the members are mainly composed of single equilateral angle steel or combined angle steel.

[0003] However, the support range of the existing device is fixed, which makes it inconvenient for staff to position the wires. To solve the above problems, we have introduced the following device. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an assembled crossarm structure for use in power towers, which has the feature of facilitating the adjustment of the support range of the conductor.

[0006] (2) Technical solution

[0007] To achieve the above objectives, this utility model provides an assembled crossarm structure for power towers, including a support platform, a fixing mechanism, and a first bearing. The fixing mechanism is fixedly connected to the side of the support platform. There are two sets of fixing mechanisms, symmetrically arranged on the side of the support platform. The first bearing passes through the surface of the support platform, and a first rotating shaft passes through the first bearing. A turntable is fixedly connected to the lower end of the first rotating shaft, and a threaded column is fixedly connected to the upper end of the first rotating shaft. A second rotating shaft is fixedly connected to the upper end of the threaded column. A second bearing is fixedly connected to the inner wall of the support platform, and the upper end of the second rotating shaft passes through the second bearing. A threaded cap is threadedly connected to the surface of the threaded column, and a connecting rod is fixedly connected to the side of the threaded cap. A movable groove is opened on the surface of the support platform, and the connecting rod passes through the movable groove. A movable rod is movably connected to the side of the connecting rod through a pin. A positioning housing is fixedly connected to the side of the support platform, and a support rod passes through the inside of the positioning housing. A fixing block is fixedly connected to the lower surface of the support rod, and the lower end of the fixing block is movably connected to the upper end of the movable rod through a pin.

[0008] When using an assembled crossarm structure for power towers according to this technical solution, by setting threaded columns and threaded caps, when it is necessary to adjust the support range of the device, one only needs to rotate the turntable, thereby driving the threaded columns to rotate. With the cooperation of the threaded columns and threaded caps, the movable rod is moved. With the cooperation of the movable rod and the fixed block, the support rod is moved. When the support rod moves to the designated position, one only needs to stop rotating the turntable, thereby achieving the adjustment of the support range of the device. At the same time, with the cooperation of the positioning housing, the support rod can be directionally moved, avoiding jamming of the support rod during the movement.

[0009] Furthermore, a limiting groove is formed on the upper surface of the support rod, and there are multiple limiting grooves, which are symmetrically formed on the upper surface of the support rod.

[0010] Furthermore, the fixing mechanism includes a first positioning clamp, which is fixedly connected to the side of the support platform. A second positioning clamp is provided on the side of the first positioning clamp. A first connecting block is fixedly connected to the side of the first positioning clamp. A second connecting block is fixedly connected to the side of the first positioning clamp.

[0024] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0025] Please see Figure 1-3This utility model provides a technical solution: an assembled crossarm structure for power towers, including a support platform 1, a fixing mechanism 2, and a first bearing 3. The fixing mechanism 2 is fixedly connected to the side of the support platform 1. There are two sets of fixing mechanisms 2, symmetrically arranged on the side of the support platform 1. The first bearing 3 passes through the surface of the support platform 1, and a first rotating shaft 4 passes through the first bearing 3.

A second rotating shaft 7 is fixedly connected to the upper end of the threaded column 6. A third rotating shaft 7 is fixedly connected to the inner wall of the support platform 1. The upper end of the second bearing 8 and the second rotating shaft 7 are inserted into the second bearing 8. The threaded column 6 is threaded with a threaded cap 9. The threaded cap 9 is fixedly connected to the side of the connecting rod 10. The support platform 1 has a movable groove 11. The connecting rod 10 is inserted into the movable groove 11. The side of the connecting rod 10 is movably connected to the movable rod 12 by a pin. The side of the support platform 1 is fixedly connected to the positioning housing 13. The positioning housing 13 is inserted into the support rod 14. The lower surface of the support rod 14 is fixedly connected to the fixing block 15. The lower end of the fixing block 15 is movably connected to the upper end of the movable rod 12 by a pin.

[0026] By adopting the above technical solution, this assembled crossarm structure applied to power towers, through the setting of threaded column 6 and threaded cap 9, when it is necessary to adjust the support range of the device, it is only necessary to rotate the turntable 5, thereby driving the threaded column 6 to rotate. With the cooperation of the threaded column 6 and threaded cap 9, the movable rod 12 is moved. With the cooperation of the movable rod 12 and the fixed block 15, the support rod 14 is moved. When the support rod 14 moves to the designated position, it is only necessary to stop rotating the turntable 5, thereby achieving the adjustment of the support range of the device. At the same time, with the cooperation of the positioning housing 13, the support rod 14 can be directionally moved, avoiding jamming of the support rod 14 during the movement.

[0027] Specifically, a limiting groove 16 is provided on the upper surface of the support rod 14. There are multiple limiting grooves 16, which are symmetrically provided on the upper surface of the support rod 14.

[0028] By adopting the above technical solution, this assembled crossarm structure applied to power towers, by setting a limiting groove 16, when people need to position the conductor, they only need to snap the conductor into the limiting groove 16 and then fix it with the wire clip, thereby achieving the purpose of positioning the conductor and improving the practicality of the device.

[0029] Specifically, the fixing mechanism 2 includes a first positioning clamp 201, which is fixedly connected to the side of the support platform 1. A second positioning clamp 202 is provided on the side of the first positioning clamp 201. A first connecting block 203 is fixedly connected to the side of the first positioning clamp 201.

A fixing bolt 205 passes through the surface of the first connecting block 203. The first connecting block 203 and the second connecting block 204 are fixedly connected by the fixing bolt 205.

[0030] It should be noted that, in terms of the fixing mechanism, an anti-slip design can be added, such as setting anti-slip textures or rubber pads (not shown) on the contact surfaces of the first and second positioning clamps to improve the stability of the fixing.

[0031] It should be noted that, to increase accuracy, scale markings can be set next to the threaded post to improve adjustment precision.

[0032] By adopting the above technical solution, this assembled crossarm structure applied to power towers, through the setting of the fixing mechanism 2, when people need to fix the device, they only need to snap the first positioning clip 201 and the second positioning clip 202 onto the surface of the power tower, and then fix the first connecting block 203 and the second connecting block 204 with the fixing bolts 205, thereby achieving the purpose of fixing the device, so that the device can maintain a stable working state during normal operation.

[0033] The working principle of this utility model is as follows: In use, the device only needs to be moved to a suitable position. When the device needs to be fixed, the first positioning clip 201 and the second positioning clip 202 are simply snapped onto the surface of the power tower, and then the first connecting block 203 and the second connecting block 204 are fixed using fixing bolts 205, thereby achieving the purpose of fixing the device and ensuring a stable working state during normal operation. When the support range of the device needs to be adjusted, the turntable 5 is rotated, thereby driving the threaded column 6 to rotate. With the cooperation of the cap 9, the movable rod 12 is moved. With the cooperation of the movable rod 12 and the fixed block 15, the support rod 14 is moved. When the support rod 14 moves to the designated position, people only need to stop rotating the turntable 5, thereby adjusting the support range of the device. At the same time, with the cooperation of the positioning housing 13, the support rod 14 can move in a directional manner, avoiding jamming during the movement of the support rod 14. When people need to position the wire, they only need to clip the wire into the limiting groove 16 and then fix it with the wire clip, thereby achieving the purpose of positioning the wire and improving the practicality of the device.
