Description

Technical Field

[0001] This utility model relates to a conductor crossarm, specifically a high-strength conductor crossarm for power towers. Background Technology

[0002] A power crossarm is an angle iron fixed horizontally at the top of a utility pole. It is used to install insulators and fittings, support conductors and lightning protection wires, and maintain a safe distance between them as required.

[0003] Most existing crossarms are designed as traditional straight poles, and multiple power crossarms are installed on the same utility pole at the same time. This installation method often has the following problems: Since the crossarms installed on the same utility pole are mostly of the same specification, the longitudinal position of the wires installed above and below is on the same plane. Since the wires on the crossarms are mostly installed outdoors, when the outdoor wind is strong and there are too many wires installed at the same time, it is easy to cause interference between the wires installed above and below. In addition, the existing crossarms cannot be folded or stored, so when workers carry the crossarms for installation, the crossarms occupy a lot of space, which is not conducive to carrying or transporting them.

[0004] Therefore, this application designs a high-strength conductor crossarm for power towers. Utility Model Content

[0005] The main objective of this disclosure is to provide a high-strength conductor crossarm for power towers, so as to effectively solve the problems raised by the inventors in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-strength conductor crossarm for power towers includes a power tower body and a crossarm body. Both ends of the crossarm body are fixedly installed on the power tower body. Two locking seats are movably installed at the bottom of the crossarm body, and a reinforcing diagonal brace is movably installed on each locking seat. The end of the reinforcing diagonal brace away from the locking seat is fixedly connected to the power tower body. The reinforcing diagonal brace, the crossarm body, and the side of the power tower body form a triangular stable structure.

[0008] Preferably, a powerful rotating shaft is rotatably mounted on the lock seat, and the reinforced diagonal brace is fixedly mounted on the powerful rotating shaft. The length of the reinforced diagonal brace is less than half the length of the main body of the crossbeam.

[0009] Preferably, the bottom of the crossarm body is provided with a straight groove, and a guide slide rod is fixedly installed in the straight groove. Two left and right moving sliders are slidably installed on the guide slide rod. Two locking seats are respectively fixedly installed on the bottom of the two left and right moving sliders. The left and right moving sliders are provided with locking components to restrict the movement of the left and right moving sliders.

[0010] Preferably, the locking assembly includes a lever, a retractable block, a locking tooth, and a return torsion spring. The left and right movable slider has a notch, and the lever is rotatably installed inside the notch. The retractable block is fixedly installed on the lever and moves within the notch. The portion of the retractable block extending outside the notch is fixedly connected to the locking tooth. A return torsion spring is installed between the retractable block and the inner wall of the notch.

[0011] Preferably, the inner wall of the straight groove is provided with a slot, and an equidistant toothed row is fixedly installed in the slot, wherein the locking protrusion engages between two adjacent teeth on the equidistant toothed row.

[0012] Preferably, a plurality of insulator strings are fixedly installed on the top of the crossarm body.

[0013] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0014] (i) In this application, before the crossarm body is installed on the power tower body, the reinforcing brace and the crossarm body do not form a triangle. Since the reinforcing brace is fixed on the movable strong rotating shaft, the reinforcing brace can swing and swing to tend to be parallel to the crossarm body, thereby reducing the space occupied by the conductor crossarm and bringing convenience to its transportation.

[0015] (ii) In this application, when installing the crossarm body, first install both ends of it onto the two sides of the power tower body to initially fix it, then move the left and right sliding blocks to move it to a suitable position, then swing the reinforcing diagonal brace so that its other end can touch the power tower body, and then install and fix it. At this time, the reinforcing diagonal brace, the crossarm body, and the side of the power tower body form a triangular stable structure. This characteristic is used to improve the strength of the conductor crossarm, making its application safer and longer.

[0016] (III) In this application, during the installation of the crossarm body, the locking protrusion engages with the equidistant tooth row in the slot, restricting the movement of the left and right sliding block, thereby fixing the locking seat. Before installation, when it is necessary to move the left and right sliding block, the swinging shrink block is used to rotate the pivot, causing the locking protrusion to disengage from the slot. When the shrink block is loosened, the left and right sliding block can be locked again under the elastic force of the reset torsion spring. The operation is simple and flexible.

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.

[0026] Please see Figure 1-6 The present invention provides the following embodiments:

[0027] A high-strength conductor crossarm for power towers includes a power tower body 1 and a crossarm body 2. Both ends of the crossarm body 2 are fixedly installed on the power tower body 1. Two locking seats 4 are movably installed at the bottom of the crossarm body 2, and a reinforcing diagonal brace 3 is movably installed on each locking seat 4. The end of the reinforcing diagonal brace 3 away from the locking seat 4 is fixedly connected to the power tower body 1, and the reinforcing diagonal brace 3, the crossarm body 2, and the side of the power tower body 1 form a triangular stable structure.

[0028] Specifically, a powerful rotating shaft 5 is rotatably mounted on the lock seat 4, and a reinforced diagonal brace 3 is fixedly mounted on the powerful rotating shaft 5. The length of the reinforced diagonal brace 3 is less than half the length of the crossbeam body 2.

[0029] Specifically, a straight groove 8 is provided at the bottom of the crossarm body 2, and a guide slide rod 9 is fixedly installed in the straight groove 8. Two left and right moving sliders 7 are slidably installed on the guide slide rod 9. Two locking seats 4 are fixedly installed at the bottom of the two left and right moving sliders 7 respectively. The left and right moving sliders 7 are provided with locking components to restrict the movement of the left and right moving sliders 7.

[0030] Specifically, the locking assembly includes a lever 11, a contraction block 12, a locking tooth 13, and a reset torsion spring 14. The left and right sliding slider 7 has a notch, and the lever 11 is rotatably installed inside the notch. The contraction block 12 is fixedly installed on the lever 11 and moves inside the notch. The portion of the contraction block 12 extending outside the notch is fixedly connected to the locking tooth 13. The reset torsion spring 14 is installed between the contraction block 12 and the inner wall of the notch. The inner wall of the straight groove 8 has a slot 10, and an equidistant tooth row 15 is fixedly installed inside the slot 10. The locking tooth 13 engages between two adjacent teeth on the equidistant tooth row 15.

[0031] Specifically, several insulator strings 6 are fixedly installed on the top of the crossarm body 2.

[0032] The specific implementation method of this embodiment is as follows: Before the crossarm body is installed onto the power tower body, the reinforcing diagonal brace and the crossarm body do not form a triangle, such as... Figure 3 As shown, since the reinforced diagonal brace is fixed on the movable strong rotating shaft, the reinforced diagonal brace can swing and swing it to tend to be parallel to the main body of the crossarm, thereby reducing the space occupied by the conductor crossarm and bringing convenience to its transportation.

[0033] When installing the crossarm body, first install both ends onto the two sides of the power tower body to initially fix it. Then move the slider left and right to move it to the appropriate position. Next, swing the reinforcing diagonal brace so that its other end can touch the power tower body. Then install and fix it. At this time, the reinforcing diagonal brace, the crossarm body, and the side of the power tower body form a triangular stable structure. This characteristic is used to improve the strength of the conductor crossarm, making its application safer and longer.

[0034] During the installation of the crossarm body, the locking protrusion engages with the equidistant toothed row in the slot, restricting the movement of the left and right sliding block, thereby fixing the locking seat. Before installation, if the left and right sliding block needs to be moved, the swinging retraction block rotates the pivot, disengaging the locking protrusion from the slot. When the retraction block is loosened, the left and right sliding block can be locked again under the elastic force of the return torsion spring. The operation is simple and flexible.
