Description

Technical Field

[0001] This utility model relates to the field of boltless dropper clamp technology, and in particular to a forged boltless dropper clamp with an integral dropper. Background Technology

[0002] Boltless dropper clamps are devices used in power line construction, especially in high-voltage transmission lines, to fix conductors to steel towers or other supporting structures. Their design feature is that there are no bolt connections; instead, the fixing effect is achieved through other means.

[0003] Utility model CN209581205U discloses a boltless serrated dropper clamp. Its key technical features include: two mating clamps; symmetrically arranged arc-shaped connectors at the upper ends of the clamps; a first serrated structure that meshes with each other on the upper inner side of the clamps; and a toothed angle for contact wire at the lower inner side of the clamps. The clamps are fixed by U-shaped clips, and the clamps have openings for the U-shaped clips to pass through. The U-shaped clip includes a slot near the insertion end, in which a clip is rotatably connected. The upper end of the clip is connected to the U-shaped clip via a pressure spring, and a stop is provided on the U-shaped clip to prevent further rotation of the clip. The U-shaped clip in this utility model makes installation between dropper clamps more convenient, and the absence of bolts avoids the impact of nuts falling off. The addition of serrations further prevents misalignment between the clamps and allows for better positioning of the clamps.

[0004] Regarding the above-mentioned issues, the following technical defects exist: The forged boltless dropper clamp body of the integral dropper is one of the important components of the contact network device of high-speed electrified railways. Its main function is to control the height of the contact wire, improve the elasticity and uniformity of the contact network, achieve good current collection quality, and ensure the harmony of the pantograph-catenary relationship. Usually, when two dropper clamp bodies are connected to each other, they are connected by screws. However, when dropper clamp bodies are connected by bolts, the bolts may loosen over a long period of use. Loose bolts will affect the connection stability of the two bodies, thus causing the connection between the two dropper clamp bodies to loosen, thereby affecting the safety and effectiveness of the two dropper clamp bodies in use.

[0005] Therefore, it is necessary to provide a new type of forged boltless dropper clamp for integral dropper to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where two dropper clamp bodies are connected by screws or bolts. Over time, the bolts may loosen, affecting the stability of the connection and consequently impacting the safety and effectiveness of the two dropper clamp bodies.

[0007] To solve the above-mentioned technical problems, this utility model provides a forged boltless dropper clamp with an integral dropper, comprising: two dropper clamp bodies, the two dropper clamp bodies having a common adjustment device on their sides, the adjustment device including two connecting holes, the two connecting holes being respectively opened on the sides of the two dropper clamp bodies, the inner walls of the two connecting holes being threaded through a common rotating rod, one end of the arc surface of the rotating rod being fixedly connected to a rotating block, one end of the dropper clamp body being fixedly connected to two fixing blocks, the two fixing blocks being rotatably connected to a common connecting rod on their sides close to each other, one end of the arc surface of the connecting rod being fixedly connected to an adjusting plate, the arc surface of the rotating rod slidingly penetrating the inner walls of the two adjusting plates.

[0008] The effects achieved by the above-mentioned components are as follows: The forged boltless dropper clamp body of the integral dropper is one of the important components of the contact network device of high-speed electrified railways. Its main function is to control the height of the contact wire, improve the elasticity and uniformity of the contact network, achieve good current collection quality, and ensure the harmony of the pantograph-catenary relationship. Usually, when two dropper clamp bodies are connected to each other, they are connected by screws. However, when dropper clamp bodies are connected by bolts, the bolts may loosen over a long period of use. Loose bolts will affect the connection stability of the two dropper clamp bodies, thus causing the connection between the two dropper clamp bodies to loosen, thereby affecting the safety and performance of the two dropper clamp bodies. At this time, an adjustment device can be used to replace the bolts to connect the two dropper clamp bodies to each other. By adjusting the device, the stability of the connection between the two dropper clamp bodies can be improved, and the overall safety of the dropper clamp body can be improved.

[0009] Preferably, a plurality of anti-slip grooves are fixedly connected to one end of the arc surface of the rotating block, and the plurality of anti-slip grooves are evenly distributed on one side of the rotating block.

[0010] The effect achieved by the above components is that when the rotating block drives the rotating rod to rotate in the connecting hole, the anti-slip groove on the rotating block can increase the friction of the rotating block surface, thereby improving the stability of the rotating block during use.

[0011] Preferably, a protective ring is fixedly connected to the side of the rotating block away from the anti-slip groove, and the cross-section of the protective ring is circular.

[0012] The effect achieved by the above components is that when the rotating block contacts one side of the adjusting plate under the action of the rotating rod, the protective ring installed on the rotating block can improve the stability of the contact between the rotating block and the adjusting plate, and avoid wear when the two are in contact, thus affecting the service life of the rotating block.

[0013] Preferably, both ends of the arc surface of the connecting rod are slidably connected to coil springs, and the two ends of the coil springs are respectively fixedly connected to the fixing block and the adjusting plate.

[0014] The effect achieved by the above components is that when the two dropper clamp bodies are removed from the installation, the coil spring installed on the connecting rod can quickly drive the adjusting plate to move away from the dropper clamp bodies, thereby quickly releasing the installation effect of the adjusting device on the two dropper clamp bodies, and the two dropper clamp bodies can be quickly separated.

[0015] Preferably, a guide block is fixedly connected to one end of the rotating rod away from the arc surface of the rotating block, and the guide block is funnel-shaped.

[0016] The effect achieved by the above components is that when the rotating rod connects with the inner wall of the connecting hole, the guide block installed on the rotating rod can increase the speed at which the rotating rod connects with the inner wall of the connecting hole, thereby improving the efficiency of the connection between the rotating rod and the inner wall of the connecting hole.

[0017] Preferably, protective pads are fixedly connected to the sides of the two dropper clamp bodies that are close to each other, and the cross-section of the protective pads is rectangular.

[0018] The effect achieved by the above components is that when the two dropper clamp bodies come into contact with each other, the protective pads installed on the two dropper clamp bodies can prevent the two dropper clamp bodies from directly contacting each other, thereby preventing wear caused by direct contact.

[0019] Preferably, the connecting rod is a titanium alloy rod.

[0020] The aforementioned components achieve the following effects: the connecting rod made of titanium alloy has a relatively hard surface, is less prone to deformation even after long-term use, and has a good service life.

[0021] Compared with related technologies, the forged boltless dropper clamp of the integral dropper provided by this utility model has the following advantages:

[0022] This utility model provides a forged boltless dropper clamp for an integral dropper. By setting an adjustment device, when two dropper clamps are connected, the adjustment device can be used to further tighten and fix the two dropper clamps. The adjustment device can improve the stability of the connection between the two dropper clamps. The two dropper clamps are also less likely to loosen after a long period of connection, and the stability and safety of use are good. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 4 The present invention provides a forged boltless dropper clamp for integral dropper, comprising: two dropper clamp bodies 1, wherein the sides of the two dropper clamp bodies 1 are provided with the same adjustment device 2.

[0031] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting device 2 includes two connecting holes 201, which are respectively opened on the sides of the two dropper clamp bodies 1. The inner walls of the two connecting holes 201 are threaded through the same rotating rod 202. One end of the arc surface of the rotating rod 202 is fixedly connected to a rotating block 206. One end of the dropper clamp body 1 is fixedly connected to two fixing blocks 203. The side of the two fixing blocks 203 that is close to each other is rotatably connected to the same connecting rod 204. One end of the arc surface of the connecting rod 204 is fixedly connected to an adjusting plate 205. The arc surface of the rotating rod 202 slides through the inner walls of the two adjusting plates 205. The forged boltless dropper clamp body 1 of the integral dropper is one of the important components of the contact wire device of high-speed electrified railway. Its main function is to control the height of the contact wire. To improve the elasticity and uniformity of the contact wire, achieve good current collection quality, and ensure the harmony of the pantograph-catenary relationship, the two dropper clamp bodies 1 are usually connected by screws. However, with prolonged use, the bolts on the dropper clamp bodies 1 can loosen, affecting the connection stability and thus impacting the safety and performance of the two dropper clamp bodies 1. In this case, an adjusting device 2 can be used instead of bolts to connect the two dropper clamp bodies 1. The adjusting device 2 improves the stability of the connection between the two dropper clamp bodies 1, enhancing the overall safety of the dropper clamp bodies 1. The arc of the rotating block 206... A plurality of anti-slip grooves 208 are fixedly connected to one end of the rotating block 206. These anti-slip grooves 208 are evenly distributed on one side of the rotating block 206. When the rotating block 206 drives the rotating rod 202 to rotate within the connecting hole 201, the anti-slip grooves 208 on the rotating block 206 increase the friction on its surface, thereby improving the stability of the rotating block 206 during use. A protective ring 207 is fixedly connected to the side of the rotating block 206 away from the anti-slip grooves 208. The protective ring 207 has a circular cross-section. When the rotating block 206 contacts the adjusting plate 205 under the action of the rotating rod 202, the protective ring 207 on the rotating block 206 improves the stability of the contact between the rotating block 206 and the adjusting plate 205, preventing... To prevent wear during contact between the two components and thus extend the service life of the rotating block 206, coil springs 210 are slidably connected to both ends of the arc surface of the connecting rod 204. The two ends of the coil springs 210 are fixedly connected to the fixed block 203 and the adjusting plate 205, respectively. When the two dropper clamp bodies 1 are disengaged, the coil springs 210 on the connecting rod 204 can quickly move the adjusting plate 205 away from the dropper clamp body 1, thereby quickly releasing the installation effect of the adjusting device 2 on the two dropper clamp bodies 1. The two dropper clamp bodies 1 can then be quickly separated. A guide block 209 is fixedly connected to the arc surface of the rotating rod 202 away from the rotating block 206. The guide block 209 is funnel-shaped. When the rotating rod 202 connects with the inner wall of the connecting hole 201...The guide block 209 installed on the rotating rod 202 can increase the speed at which the rotating rod 202 connects with the inner wall of the connecting hole 201, thereby improving the efficiency of the connection. Protective pads 211 are fixedly connected to the sides of the two dropper clamp bodies 1 that are close to each other. The protective pads 211 have a rectangular cross-section. When the two dropper clamp bodies 1 come into contact with each other, the protective pads 211 prevent direct contact, thus avoiding wear caused by direct contact. The connecting rod 204 is made of titanium alloy. The titanium alloy connecting rod 204 has a relatively hard surface, is less prone to deformation even after long-term use, and has a good service life.

[0032] The working principle of the forged boltless dropper clamp of the integral dropper provided by this utility model is as follows: Two dropper clamp bodies 1 are brought into contact. The connecting rod 204 is rotated on the fixing block 203. The movement of the connecting rod 204 drives the adjusting plate 205 to move. Both adjusting plates 205 are rotated to one side of the connecting hole 201. At this time, the inner walls of the two adjusting plates 205 are aligned with the inner walls of the connecting hole 201. Then, the rotating rod 202 is rotated by the rotating block 206 within the inner walls of the adjusting plates 205 and the connecting hole 201. The rotating rod 202 then fixes the two adjusting plates 205 to one side of the dropper clamp body 1, and the two dropper clamp bodies 1 are fixed together. This completes the installation of the two dropper clamp bodies 1.

[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
