Description

Steering saddle for bridge construction Technical Field

[0001] This invention relates to the field of bridge construction, and more specifically, to a steering saddle for bridge construction. Background Technology

[0002] The steering saddle used in bridge construction is a core guiding and load-bearing component in the construction phase of cable-stayed bridges such as suspension bridges and cable-stayed bridges. Its core function is to change the direction of force on the main cable (or traction cable) and support the vertical load of the main cable, ensuring the stress stability of the main cable during erection, tensioning and after the completion of the bridge.

[0003] For example, the Chinese utility model patent (application number: 202421246195.3) discloses a "steering cable saddle for bridge construction," the description of which states that during the installation of the water-retaining seat, as the water-retaining seat slowly approaches the steering cable saddle, the steel cable in the saddle groove will move the control rod at the bottom of the water-retaining seat, causing the control rod to rotate. During the rotation of the control rod, a series of transmissions will cause the sealing cover to slide, aligning the oil outlet and the oil leakage hole, allowing lubricating oil to flow into the oil outlet pipe. Simultaneously, the foam block and diversion hole can divert the lubricating oil in the oil outlet pipe, reducing the flow rate of the lubricating oil, allowing the lubricating oil to slowly flow into the cable saddle groove to lubricate and maintain the steel cable; however, the above-mentioned bridge construction... The existing steering saddle has some shortcomings in actual use: In the above-mentioned existing technology, lubricating oil is dripped into the saddle groove and main cable through the oil outlet pipe. Since the lubricating oil in the existing technology is grease, the grease has poor fluidity. When the grease falls freely from the oil outlet pipe onto the saddle groove and main cable, the grease is difficult to spread due to its high viscosity. Most of it can only adhere to the surface of the main cable and the raised parts of the saddle groove. It is difficult to penetrate into the splicing joints of the wear-resistant modules of the saddle groove, the twisting gaps of the main cable wires, and other hidden places. This results in a small effective area for the grease to act, and many lubrication blind spots are formed in the saddle groove and main cable, which leads to a reduction in the service life of the steering saddle and main cable. Therefore, we have made improvements and proposed a steering saddle for bridge construction. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the lubrication efficiency of the saddle groove and main cable in the existing steering saddle is low, resulting in many lubrication blind spots between the saddle groove and the main cable, which leads to a reduction in the service life of the steering saddle and the main cable.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0018] As described in the background art, the lubrication efficiency of the saddle groove and the main cable of the steering saddle is low, which results in a large number of lubrication blind spots between the saddle groove and the main cable, leading to a reduction in the service life of the steering saddle and the main cable.

[0019] To solve this technical problem, the present invention provides a steering saddle for bridge construction, which is applied to bridge construction.

[0020] Specifically, please refer to Figures 1-7. The steering saddle for bridge construction includes: a saddle body 1, including a mounting base 101 on the saddle body 1 and a spraying mechanism 2 on the mounting base 101; the spraying mechanism 2 includes a sealing cavity 201 on the mounting base 101, a cylinder 202 on the mounting base 101, a push plate 203 on the cylinder 202, a transmission plate 204 in the sealing cavity 201, a drive plate 205 on the transmission plate 204, a guide groove 206 on the drive plate 205, a piston 207 on the guide groove 206, a pressure valve 208 on the piston 207, a hollow seat 209 on the piston 207, and an oil outlet 210 on the hollow seat 209.

[0021] The present invention provides a steering cable saddle for bridge construction. To address the problem in existing technologies where the lubrication efficiency of the saddle groove and main cable is low, resulting in numerous lubrication blind spots and reduced service life of the saddle and main cable, this application utilizes a spraying mechanism 2. This mechanism drives grease to specifically lubricate the saddle groove and main cable of the cable saddle body 1, reducing grease waste, improving utilization, minimizing lubrication blind spots, and extending the service life of the cable saddle body 1 and main cable. Furthermore, the spraying mechanism 2, through the upward sliding piston 207… The spray mechanism 2 moves and pushes the grease on it, disturbing the grease in the sealed cavity 201, reducing the grease from settling and separating, and improving the service life of the grease. This solves the problem of reduced service life caused by grease settling in the prior art. Through the spray mechanism 2, the piston 207 slides downward and drives the air outlet 212 to discharge air, so that the generated air pressure can form a directional thrust, carrying the grease into the gap between the saddle groove of the cable saddle body 1 and the main cable, improving the permeability of the grease. This solves the problem of low grease permeability in the prior art, which leads to more lubrication blind spots.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Example 1, please refer to Figures 1, 2, 3, 4, 5, 6, and 7. A steering saddle for bridge construction has a push plate 203 slidably disposed within a sealed cavity 201. A guide groove 206 communicates with the sealed cavity 201, and a pressure valve 208 communicates with both the guide groove 206 and the hollow seat 209. In use, as shown in Figure 2, the cylinder 202 is activated. The output of the cylinder 202 drives the push plate 203 to slide downwards along the sealed cavity 201. The sealed cavity 201 is filled with grease. The downward sliding of the push plate 203 compresses the grease, causing it to enter the guide groove 209. Within 06, the grease enters the guide groove 206 and squeezes the piston 207 and pressure valve 208. At this time, the grease enters the hollow seat 209 from the pressure valve 208, and finally exits from the oil outlet 210 on the hollow seat 209, as shown in Figure 4. The oil outlet 210 is aligned with the gap between the saddle groove of the cable saddle body 1 and the main cable. The grease discharged through the oil outlet 210 provides targeted lubrication to the saddle groove of the cable saddle body 1 and the main cable. Compared with existing technologies, where grease is lost or accumulates in non-friction areas due to gravity through traditional free dripping, resulting in grease waste, targeted lubrication reduces... This reduces grease waste, improves utilization, and decreases lubrication blind spots, thereby extending the service life of the saddle body 1 and the main cable. Furthermore, the piston 207 is slidably mounted on the guide groove 206, and springs 211 are provided on the corresponding surfaces of the drive plate 205 and the piston 207. The hollow seat 209 is slidably mounted on the guide groove 206. When the output end of the cylinder 202 drives the push plate 203 to slide downwards along the sealing cavity 201, the grease in the sealing cavity 201 squeezes the piston 207 and the pressure valve 208. At this time, the piston 207 slides along the guide groove 206, and the hollow seat 209 and the piston 207 move synchronously. Sliding, spring 211 is squeezed and compressed by piston 207 to store force. When the grease is discharged through pressure valve 208, hollow seat 209 and oil outlet 210, the cylinder 202 drives the push plate 203 to reset. At this time, spring 211 elastically drives piston 207 to slide upward and reset. Piston 207 slides upward and pushes the grease on it, disturbing the grease in the sealing cavity 201, reducing the grease stratification and improving the service life of the grease. Furthermore, the drive plate 205 is provided with an air outlet 212, which is connected to the guide groove 206.As the piston 207 slides downwards along the guide groove 206, as shown in Figure 5, the piston 207 divides the guide groove 206 into an upper region and a lower region. The region above the piston 207 contains lubricating grease, while the region below the piston 207 is connected to the outside through the vent 212. When the piston 207 slides downwards, it compresses the air in the region below the guide groove 206, causing the air to be discharged from the vent 212. The vent 212 is aligned with the gap between the saddle groove of the saddle body 1 and the main cable. Due to the high viscosity of the lubricating grease, the air discharged through the vent 212... This allows the generated air pressure to form a directional thrust, carrying the lubricating grease deep into the gap between the saddle groove of the cable saddle body 1 and the main cable, improving the permeability of the lubricating grease and enhancing the lubrication effect. Furthermore, a motor 213 is mounted on the mounting base 101, and a screw 214 is rotatably mounted on the mounting base 101. The screw 214 is located at the output end of the motor 213, and a transmission plate 204 is threadedly connected to the screw 214. A sliding groove 215 is provided on the mounting base 101, and a drive plate 205 is slidably mounted on the sliding groove 215. The transmission plate 204 is slidably mounted within the sealed cavity 201. By starting the motor 213, the electric... The output end of the machine 213 drives the screw 214 to rotate, the screw 214 drives the transmission plate 204 to slide, and the drive plate 205 on the transmission plate 204 slides synchronously along the sliding groove 215. By adjusting the position of the drive plate 205 in the sliding groove 215, the oil outlet 210 is moved to the other side of the gap between the saddle groove of the cable saddle body 1 and the main cable, so that the oil outlet 210 provides equal lubrication to both sides of the gap between the saddle groove of the cable saddle body 1 and the main cable. In this way, the frictional resistance on both sides of the gap between the saddle groove of the cable saddle body 1 and the main cable is balanced, and the lateral deflection of the main cable is prevented. The spraying mechanism 2 drives the grease to apply to the cable saddle body. Targeted lubrication of the saddle groove and main cable reduces grease waste, improves utilization, reduces lubrication blind spots, and extends the service life of the saddle body 1 and the main cable. The piston 207 slides upwards, pushing the grease on it and agitating the grease within the sealed cavity 201, reducing grease stratification and extending its service life. The piston 207 slides downwards, driving air out through the vent 212, creating a directional thrust that carries the grease deep into the gap between the saddle groove and the main cable, improving grease penetration and lubrication effectiveness.

[0026] Example 2 further optimizes the steering saddle for bridge construction provided in Example 1. Specifically, as shown in Figures 2, 3, 4, 5, 6, and 7, the mounting base 101 is provided with a pressing groove 216, and a jacking block 217 is slidably disposed on the pressing groove 216. A spring 218 is disposed on the corresponding surface of the jacking block 217 and the pressing groove 216, and a semi-circular groove 219 is disposed on the transmission plate 204; furthermore, the jacking block 217 rotates... A ball bearing 220 is provided, which is adapted to the semi-circular groove 219. When the drive plate 205 and the transmission plate 204 slide synchronously along the sliding groove 215, the ball bearing 220 and the semi-circular groove 219 disengage. The ball bearing 220 and the push block 217 slide along the pressing groove 216, and the second spring 218 is pressed and compressed. When the ball bearing 220 and the semi-circular groove 219 engage, the second spring 218 elastically drives the ball bearing 220 to press the semi-circular groove 219. The ball bearings 220 impact the semi-circular groove 219, causing the transmission plate 204 and the mounting base 101 to vibrate. Poor contact between the main cable and the saddle groove of the saddle body 1 in some areas leads to uneven stress. Vibration optimizes the fit between the main cable and the saddle groove of the saddle body 1, improving load-bearing stability. Furthermore, a filter screen 221 with a guide ring 222 is installed on the mounting base 101. The filter screen 221 filters out external dust and impurities. The main cable slides on the guide ring 222. Because the saddle groove on the saddle body 1 is arched, grease slides along the saddle groove and contacts the guide ring 222, lubricating the guide ring 222 and reducing friction between the guide ring 222 and the main cable, thus improving grease utilization. The filter screen 221 and guide ring 222 are made of flexible material, absorbing grease and reducing grease loss.The application process of the steering saddle for bridge construction provided by this invention is as follows: During use, the cylinder 202 is activated. The output end of the cylinder 202 drives the push plate 203 to slide downwards along the sealed cavity 201, which is filled with grease. The push plate 203 slides downwards and squeezes the grease, causing it to enter the guide groove 206. The grease squeezes the piston 207 and pressure valve 208, causing the piston 207 to slide along the guide groove 206. The hollow seat 209 slides synchronously with the piston 207, and the spring 211 is compressed and stored by the piston 207. At this time, the grease enters the hollow seat 209 from the pressure valve 208, and finally exits from the oil outlet 210 on the hollow seat 209. The oil outlet 210 is aligned with... The grease discharged through the oil outlet 210 in the gap between the saddle groove of the cable saddle body 1 and the main cable provides targeted lubrication to both. Simultaneously, the piston 207 divides the guide groove 206 into an upper and lower region. The region above the piston 207 contains the grease, while the region below the piston 207 is connected to the outside through the vent 212. When the piston 207 slides downwards, it compresses the air in the region below the guide groove 206, causing the air to be discharged through the vent 212. The vent 212 is aligned with the gap between the saddle groove of the cable saddle body 1 and the main cable. Due to the high viscosity of the grease, the air discharged through the vent 212 generates a directional thrust, carrying the grease towards the cable. The grease flows deep into the gap between the saddle body 1 saddle groove and the main cable, improving the permeability of the grease. After the grease is discharged through the pressure valve 208, hollow seat 209 and oil outlet 210, the cylinder 202 drives the push plate 203 to reset. At this time, the spring 211 drives the piston 207 to slide upward and reset through elasticity. The piston 207 slides upward and pushes the grease on it, disturbing the grease in the sealing cavity 201 and reducing the grease stratification. By starting the motor 213, the output end of the motor 213 drives the screw 214 to rotate. The screw 214 drives the transmission plate 204 to slide. The drive plate 205 on the transmission plate 204 slides synchronously along the sliding groove 215. When the drive plate 205 and the transmission plate 204 slide synchronously along the sliding groove 215, the grease is released into the air. When groove 215 slides, and the ball 220 and semi-circular groove 219 disengage, the ball 220 and the jacking block 217 slide along the compression groove 216, and the second spring 218 is compressed. When the ball 220 and semi-circular groove 219 engage, the second spring 218 elastically drives the ball 220 to compress the semi-circular groove 219. The impact of the ball 220 on the semi-circular groove 219 causes the transmission plate 204 and the mounting base 101 to vibrate. This vibration optimizes the fit between the main cable and the saddle groove of the saddle body 1. By adjusting the position of the drive plate 205 in the sliding groove 215, the oil outlet 210 is moved to the other side of the gap between the saddle groove of the saddle body 1 and the main cable, so that the oil outlet 210 provides equal lubrication to both sides of the gap between the saddle groove of the saddle body 1 and the main cable.
