Cement single-pole linear cross arm

Abstract

The utility model relates to the technical field of power lines, in particular to a cement single-pole linear cross arm. Comprising a cross rod, hoops and bolts. A positioning block is fixedly arranged on the cross rod; the bolts are arranged on the two sides of the positioning block respectively. The hoops are in one-to-one correspondence with the bolts; the hoop is connected with the bolt in a swinging manner; the swing paths of the hoops intersect so as to embrace each other. In the prior art, when a worker assembles a cross arm, one bolt needs to be disassembled firstly, so that a nut and a gasket are prone to falling off, and work of the worker is affected. Compared with the prior art, in the assembling process, bolts do not need to be disassembled, only the primary hoop and the secondary hoop need to be mutually hooped together, and therefore the risk that small parts fall off is effectively avoided.

Description

TECHNICAL FIELD

[0001] The utility model relates to power line technical field especially relates to a cement single pole straight line cross arm. BACKGROUND

[0002] The tower is the support of overhead transmission line and is the main support structure of overhead transmission line. The main components of the tower include the cement pole and the cross arm. The cross arm is the angle iron fixed horizontally on the top of the cement pole. Its function is to install the insulator and the hardware to support the conductor and the lightning conductor and to ensure that they maintain the specified safety distance.

[0003] Specifically, the cross arm includes the cross bar and the hoop. The positioning block is welded at the midpoint of the cross bar. The positioning block is in the shape of a circular arc matching the diameter of the cement pole. The hoop is fixed on the cross bar by two bolts. The hoop corresponds to the positioning block. Thus, the staff can rotate the nut on the bolt to tightly clamp the hoop and the positioning block on both sides of the cement pole to complete the assembly of the cross arm. However, in actual operation, the height of the cement pole is high, and the assembly position of the cross arm is usually at the end of the cement pole, which requires the staff to first climb to the designated position and then use the corresponding hoisting tool to hoist the cross arm or directly shoulder the cross arm to climb. Regardless of the form, in order to prevent the loss of nuts and other small parts during transportation, the hoop needs to be pre-assembled on the cross bar. Therefore, during assembly, the staff needs to first remove one of the bolts, then set the hoop and the positioning block on both sides of the cement pole, and then tighten the two bolts. The nuts, gaskets and other parts are relatively small, and the parts may fall during the bolt removal process, which seriously affects the work of the staff. SUMMARY

[0004] In view of the technical problems of the prior art, the utility model provides a cement single pole straight line cross arm.

[0005] To solve the above technical problems, the utility model provides the following technical scheme:

[0006] A cement single pole straight line cross arm, comprising: a cross bar, a hoop, and a bolt; the cross bar is fixedly provided with a positioning block; the bolt is arranged on both sides of the positioning block; the hoop corresponds to the bolt one by one; the hoop is swingably connected with the bolt; the swing paths of the hoops intersect to embrace each other.

[0007] Further, the hoop is fixedly provided with a fixed column at the end away from the bolt; the hoop is provided with a clamping groove at the end close to the bolt; the fixed column of one of the hoops can be embedded in the clamping groove of the other hoop.

[0008] Further, the hoop is further provided with a through groove; the thickness of the other hoop corresponds to the through groove to pass through the through groove.

[0009] Further, the hoop is in an arc shape corresponding to the positioning block.

[0010] Further, one end of the bolt penetrates the crossbar; the other end of the bolt is fixedly provided with a swing shaft; the swing shaft is embedded in the hoop; the hoop is provided with a position-avoiding groove corresponding to the bolt. BRIEF DESCRIPTION OF DRAWINGS

[0015] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0016] A cement single-pole straight linear cross arm, comprising: a crossbar 1, a hoop 2, and a bolt 3. The crossbar 1 is fixedly provided with a positioning block 11. The positioning block 11 is in an arc shape corresponding to the cement pole.

[0017] The bolt 3 is arranged on both sides of the positioning block 11. One end of the bolt 3 penetrates the crossbar 1. The other end of the bolt 3 is fixedly provided with a swing shaft 31. The swing shaft 31 is embedded in the hoop 2. The hoop 2 is provided with a position-avoiding groove 24 corresponding to the bolt 3.

[0018] Meanwhile, the hoop 2 corresponds to the bolt 3 one by one. The hoop 2 is swingably connected to the bolt 3. The hoop 2 is fixedly provided with a fixed column 21 at an end away from the bolt 3. The hoop 2 is provided with a clamping groove 22 at an end close to the bolt 3. The fixed column 21 of one of the hoops 2 can be embedded in the clamping groove 22 of the other hoop 2. Meanwhile, the one of the hoops 2 is further provided with a through groove 23. The thickness of the other hoop 2 corresponds to the through groove 23 to pass through the through groove 23. On the other hand, the hoop 2 is in an arc shape corresponding to the positioning block 11.

[0019] In actual application, each component is assembled together in advance, and the clamping hoop 2 is swung so that the clamping hoops 2 are not crossed. After the staff climbs to the designated position, the cross arm is hoisted by using hoisting tools. Since the clamping hoops 2 are not crossed, there is an opening between the clamping hoops 2. At this time, the position of the cross rod 1 is adjusted so that the cement rod is fitted with the positioning block 11 through the opening between the clamping hoops 2. Since the bolt 3 is in a pre-assembled state, there is sufficient space between the clamping hoop 2 and the cement rod. The staff can swing the clamping hoop 2 so that one of the clamping hoops 2 passes through the other clamping hoop 2 through the through slot 23, so that the two clamping hoops 2 are crossed together. Then, the clamping hoop 2 is continued to be swung to adjust the relative position between the clamping hoops 2, so that the fixing column 21 on one of the clamping hoops 2 is clamped into the clamping groove 22 of the other clamping hoop 2. Thus, the two clamping hoops 2 are clamped together. At this time, the staff can gradually tighten the nut on the bolt 3, so that the clamping hoop 2, the positioning block 11 and the cement rod are fully fitted, and the clamping hoop 2, the positioning block 11 are tightly clamped on both sides of the cement rod.

[0020] In summary, when assembling the cross arm, the staff does not need to disassemble small parts such as nuts, and only needs to swing the clamping hoop 2, thereby effectively avoiding the risk of falling of small parts during assembly.

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
