Description

Technical Field

[0001] This utility model belongs to the field of clamp technology, and in particular relates to a clamp crossarm. Background Technology

[0002] The crossarm is a core connecting component in power transmission and distribution systems. It consists of a crossarm and a clamp and is mainly used to fix conductors, insulators and auxiliary equipment on poles and towers. It is usually made of equilateral angle steel with hot-dip galvanized surface treatment. It is used to support conductors, lightning protection wires and insulator strings and maintain a safe distance between conductors. It consists of symmetrical semi-circular clamps, bolts and inner linings. The crossarm is fastened to the pole and tower by bolt connection.

[0003] The following problems exist when using clamp crossarms currently on the market:

[0004] 1. Traditional clamp crossarms are usually fastened to the outside of the object using bolts. However, when the fasteners are tightened repeatedly, the inside of the clamp structure rubs against the outside of the object, resulting in varying degrees of wear. Therefore, no wear-resistant structure is installed inside the clamp during use.

[0005] 2. Most clamp crossarms are used with two sets of fastening structures installed on both sides of the clamp. After a long period of use, the fastening structures and the clamp may loosen, requiring regular maintenance by staff. Therefore, no support and tightening structure is installed during use. Utility Model Content

[0006] The purpose of this utility model is to provide a clamp crossarm to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A clamp crossbeam includes a first semi-circular clamp plate and a second semi-circular clamp plate. The second semi-circular clamp plate is provided on the side of the first semi-circular clamp plate. A fixing seat is provided on the outer side of the first semi-circular clamp plate. A rubber ring is provided on the inner side of the first and second semi-circular clamp plates. A rubber strip is provided inside the rubber ring. The rubber strip is distributed in a ring shape. A ring body is provided on the side of the rubber ring. The ring body is symmetrically distributed. A positioning rod is provided on the side of the ring body. A positioning groove is opened on the outer side of the first semi-circular clamp plate. A positioning groove is opened on the outer side of the second semi-circular clamp plate. The positioning rod is embedded in the inside of the positioning groove.

[0008] Preferably, the fixed base is provided with a first fixed frame on its exterior, the second semi-circular hoop is provided with a second fixed frame on its exterior, the first fixed frame is provided with a reinforcing plate on its inner side, the reinforcing plate is provided with a fixing block on its side, the fixing block has a through hole inside, the first fixed frame and the second fixed frame are provided with a compression screw inside, the compression screw passes through the through hole, the rubber ring has a through hole inside, and the compression screw passes through the through hole.

[0009] Preferably, the outer side of the rubber ring is provided with a magnetic absorbing piece, which magnetically attracts the inner side of the first semi-circular hoop and the inner side of the second semi-circular hoop.

[0010] Preferably, mounting holes are provided on the outside of the first semi-circular hoop and the second semi-circular hoop, and a circular hole is provided on the inside of the fixing seat.

[0011] Preferably, a fastening screw is embedded inside the mounting hole, the fastening screw passes through the circular hole, and a nut is connected to the external thread of the fastening screw.

[0012] Preferably, the outer side of the fixing block is provided with a connecting plate, the connecting plates are symmetrically distributed, and the other side of the connecting plate is provided with a reinforcing plate.

[0013] The clamp crossarm of this utility model has the following advantages:

[0014] 1. This type of clamp crossarm, by installing a rubber ring and rubber strip inside the semi-circular clamp plate structure, and providing a ring body on the side of the rubber ring, and a positioning rod at the bottom of the ring body, facilitates the installation of the wear-resistant structure on the inner side of the clamp structure. When using the clamp plate, the worker first takes out the rubber structure, preliminarily pries open the ring body, embeds the positioning rod in the positioning groove, and at the same time, magnetic plates on the side of the rubber ring are magnetically attracted to the outside of the semi-circular clamp plate structure. Since the first semi-circular clamp plate and the second semi-circular clamp plate are made of metal plates, the wear-resistant structure can be installed on the inner side of the clamp structure, which can play a wear-resistant role during use.

[0015] 2. This type of clamp crossarm, by installing a first fixing frame on the outside of the first semi-circular clamp plate and a second fixing frame on the outside of the second semi-circular clamp plate, and by providing a reinforcing plate and a pressing screw inside the fixing frame structure, can perform secondary compression of the clamp structure. After the crossarm clamp is initially installed on the outside of the object using fasteners, the operator removes the pressing screw again and passes it through the first and second fixing frames respectively, to perform secondary compression of the object inside the crossarm clamp from both sides. This results in a better compression effect during application, reduces the impact of expansion on the inside of the clamp, and makes the fastening more secure. Attached Figure Description

The positioning rod 9 is embedded inside the positioning groove 10. By installing a rubber ring 6 and a rubber strip 7 inside the semi-circular hoop structure, and providing a ring body 8 on the side of the rubber ring 6, and a positioning rod 9 at the bottom of the ring body 8, when using the clamping plate, the worker first takes out the rubber structure, initially pries open the ring body 8, and embeds the positioning rod 9 into the positioning groove 10. At the same time, the magnetic suction piece 19 on the side of the rubber ring 6 is magnetically attracted to the outside of the semi-circular hoop structure. In this way, the wear-resistant structure can be installed on the inside of the clamping structure. When tightening the semi-circular hoop structure later, the rubber structure can be pressed tightly to the outside of the object.

[0030] The fixed base 3 is provided with a first fixed frame 11 on its outside, and the second fixed frame 12 is provided on its outside. The first fixed frame 11 is provided with a reinforcing plate 13 on its inside, and a fixed block 14 is provided on the side of the reinforcing plate 13. A through hole 17 is opened in the inside of the fixed block 14. A compression screw 16 is provided inside the first fixed frame 11 and the second fixed frame 12. The compression screw 16 passes through the through hole 17. A through hole 18 is opened inside the rubber ring 6. The compression screw 16 passes through the through hole 18. By installing the first fixed frame 11 on the outside of the first semicircular hoop 1, installing the second fixed frame 12 on the outside of the second semicircular hoop 2, and providing the reinforcing plate 13 and compression screw 16 inside the fixed frame structure, after the crossarm clamp is initially installed on the outside of the object with fasteners, the workers take out the compression screw 16 again and pass it through the first fixed frame 11 and the second fixed frame 12 respectively. The object inside the crossarm clamp is then pressed again from both sides. This results in a better pressing effect during application and reduces the impact of expansion on the inside of the clamp.

[0031] A magnetic absorbing piece 19 is provided on the outer side of the rubber ring 6. The magnetic absorbing piece 19 is magnetically attracted to the inner side of the first semi-circular hoop 1 and the inner side of the second semi-circular hoop 2. Due to the installation of the magnetic absorbing piece 19, the rubber ring 6 can be initially installed on the inner side of the semi-circular hoop structure by means of strong ferromagnetic attraction.

[0032] Mounting holes 20 are provided on the outside of the first semi-circular hoop 1 and the second semi-circular hoop 2, and a circular hole 21 is provided inside the fixing seat 3. Because of the mounting holes 20, it is convenient to pass the fastening screw 4 through the first semi-circular hoop 1 and the second semi-circular hoop 2.

A positioning groove 10 is opened on the outer side of the first semi-circular clamp plate 1, and a positioning groove 10 is opened on the outer side of the second semi-circular clamp plate 2. Before using the clamp, the worker first removes the rubber structure, initially pries open the ring body 8, and inserts the positioning rod 9 into the positioning groove 10. Simultaneously, the rubber ring 6 is... The magnetic clasp 19 is magnetically attached to the outside of the semi-circular hoop structure. Since the first semi-circular hoop 1 and the second semi-circular hoop 2 are made of metal sheet, the wear-resistant structure can be installed on the inside of the hoop structure, achieving a wear-resistant effect during use. Then, the worker installs the first semi-circular hoop 1 and the second semi-circular hoop 2 on the outside of the object. Next, the fastening screw 4 is removed and passed through the mounting hole 20. Then, the external nut 5 is tightened to secure it. This allows the semi-circular hoop structure to be installed on the outside of the object. However, to avoid… Due to expansion, the clamps may loosen. Therefore, a first fixing bracket 11 is installed on the outside of the first semi-circular clamp plate 1, and a second fixing bracket 12 is installed on the outside of the second semi-circular clamp plate 2. A reinforcing plate 13 and a clamping screw 16 are provided inside the fixing bracket structure. A fixing block 14 is provided on the outside of the clamping screw 4. The side of the fixing block 14 is connected to the reinforcing plate 13 via a connecting plate 15. After the crossbeam clamp is initially installed on the outside of the object using fasteners, the worker removes the clamping screw 16 again and passes it through the through hole 17 and the through hole 18 in sequence. From both sides of the first fixing bracket 11 and the second fixing bracket 12, tighten the compression screws 16 to place the second compression plate on the outside of the object. This will result in a better clamping effect during application, reduce the impact of expansion on the inside of the clamp, and make the tightening more secure. Finally, when inspecting the clamp crossarm structure, if the rubber structure is found to be severely worn, turn the nut 5 in the opposite direction to remove the first semi-circular clamp plate 1 and the second semi-circular clamp plate 2 from the outside of the object. Then, remove the damaged rubber structure and reinstall the new rubber structure inside. This completes the replacement work.
