Description

Technical Field

[0001] The present disclosure relates to the technical field of bridges, and particularly relates to a jacking guiding device and a main cable saddle for a main cable saddle. Background Art

[0002] The main cable saddle of a suspension bridge is an important component for supporting the main cable. The main cable saddle is used to place the main cable and is generally located on the top of the main tower. Usually, according to the requirements of bridge construction, the main cable saddle needs to be jacked multiple times to jack the installation position of the main cable saddle to a predetermined position on the top of the main tower.

[0003] In the related art, the main cable saddle includes: a saddle body, an upper bearing plate, and a lower bearing plate. The saddle body is located on the plate surface of the upper bearing plate. The upper bearing plate is slidably arranged on the surface of the lower bearing plate, and the lower bearing plate is installed on the surface of the top of the main tower. During the displacement construction, by jacking the saddle body, the saddle body and the upper bearing plate slide together on the surface of the lower bearing plate to a predetermined position on the top of the main tower.

[0004] However, during the jacking process of installing the main cable saddle, due to reasons such as unbalanced magnitudes of the jacking component forces, the problem that the resultant force direction of pushing the main cable saddle is not parallel to the direction required for the main cable saddle to move easily occurs. This makes the main cable saddle prone to deviation when moving to the predetermined position, and also causes contact and extrusion between the two side ends of the main cable saddle and the two side ends of the lower bearing plate, resulting in biting and jamming, which affects the displacement operation of the main cable saddle.

[0016] The beneficial effects brought by the technical solutions provided by the embodiments of the present disclosure at least include:

[0017] The jacking guiding device provided by the embodiments of the present disclosure includes an upper bearing seat and a lower bearing seat. Two parallel and spaced guiding side plates are provided on the upper bearing plate of the upper bearing seat. Among them, the upper bearing plate is a plate for carrying the saddle body of the main cable saddle. The lower bearing seat includes a lower bearing plate and at least two guiding and deviation correcting assemblies, and the guiding and deviation correcting assemblies are distributed on opposite side edges of the lower bearing plate. Among them, the guiding wheel and the force applying member of the guiding and deviation correcting assembly are fixed on the lower bearing plate through a mounting vertical plate, and the guiding wheel is clamped between the mounting vertical plate and the guiding side plate, and the force applying member is used to apply a force to the guiding wheel to make the guiding wheel approach the guiding side plate, and a certain pre-pressure is applied to the guiding wheel by the force applying member so that the guiding wheel abuts against the guiding side plate. In this way, during the jacking process of the saddle body, the guiding wheel can always abut against the guiding side plate, defining the sliding direction of the saddle body on the upper bearing plate, so that the saddle body can move along a preset direction. When the direction of the resultant jacking force received by the saddle body deviates from the preset direction, the force transmitted by the force applying member to the guiding wheel will resist the resultant jacking force, prompting the saddle body to move back to the preset direction position. Therefore, the unbalanced forces on both sides of the saddle body during jacking can be greatly reduced, realizing active deviation correction during the jacking process of the saddle body and ensuring that the saddle body moves along the preset direction. The coincidence degree between the real-time center line in the bridge longitudinal direction during the sliding of the main cable saddle and the theoretical center line of the main cable saddle in the bridge longitudinal direction is relatively good.

[0018] At the same time, the guiding wheel rotates under the action of friction, and its friction is rolling friction, which can further avoid biting and jamming between the guiding side plate and the guiding and deviation correcting assembly. Therefore, it is ensured that the main cable saddle slides smoothly and without jamming during the jacking and sliding process. Description of the Drawings

As Figure 5 , 6 shown, the lower bearing seat 20 includes: a lower bearing plate 21 and at least two guiding and correcting components 22. A part of the guiding and correcting components 22 and another part of the guiding and correcting components 22 are respectively located on opposite side edges of the lower bearing plate 21.

[0047] As Figure 2 , 3 shown, the plate surface of the upper bearing plate 11 away from the guiding side plates 12 is in sliding fit with the lower bearing plate 21, and the two guiding side plates 12 are located between a part of the guiding and correcting components 22 and another part of the guiding and correcting components 22.

[0048] Figure 7 FIG. 27 is a schematic structural view of a guiding and correcting component 22 provided by an embodiment of the present disclosure. Figure 8 FIG. 29 is a cross-sectional view of a guiding and correcting component 22 provided by an embodiment of the present disclosure. As Figure 2 , 7 , 8 shown, the guiding and correcting component 22 includes: a mounting vertical plate 221, a guiding wheel 222 and a force applying member 223. One end of the mounting vertical plate 221 is connected to the lower bearing plate 21. The guiding wheel 222 and the force applying member 223 are both located at the other end of the mounting vertical plate 221. The guiding wheel 222 and the force applying member 223 are located between the mounting vertical plate 221 and the guiding side plate 12, and the guiding wheel 222 abuts against the guiding side plate 12.

[0049] Wherein, the force applying member 223 is used to apply a force to the guiding wheel 222 to make the guiding wheel 222 approach the guiding side plate 12.

[0050] The jacking guiding device provided by the embodiments of the present disclosure includes an upper bearing seat 10 and a lower bearing seat 20. Two parallel and spaced guiding side plates 12 are arranged on the upper bearing plate 11 of the upper bearing seat 10. Among them, the upper bearing plate 11 is a plate for carrying the saddle body 30 of the main cable saddle. The lower bearing seat 20 includes a lower bearing plate 21 and at least two guiding and rectifying components 22, and the guiding and rectifying components 22 are distributed on opposite sides of the lower bearing plate 21. Among them, the guiding wheel 222 and the force applying member 223 of the guiding and rectifying component 22 are fixed on the lower bearing plate 21 through the mounting vertical plate 221. The guiding wheel 222 is clamped between the mounting vertical plate 221 and the guiding side plate 12, and the force applying member 223 is used to apply a force to the guiding wheel 222 to make the guiding wheel 222 approach the guiding side plate 12. A certain pre-pressure is applied to the guiding wheel 222 by the force applying member 223 so that the guiding wheel 222 abuts against the guiding side plate 12. In this way, during the jacking process of the saddle body 30, the guiding wheel 222 can always abut against the guiding side plate 12, defining the sliding direction of the saddle body 30 on the upper bearing plate 11, so that the saddle body 30 can move along the preset direction. When the direction of the resultant jacking force received by the saddle body 30 deviates from the preset direction, the force transmitted by the force applying member 223 to the guiding wheel 222 will resist the resultant jacking force, prompting the saddle body 30 to move back to the preset direction position. Therefore, the unbalanced forces on both sides of the saddle body 30 during jacking can be greatly reduced, realizing the active rectification of the saddle body 30 during the jacking process and ensuring that the saddle body 30 moves along the preset direction. It makes the coincidence degree between the real-time center line in the bridge longitudinal direction during the sliding of the main cable saddle and the theoretical center line of the main cable saddle in the bridge longitudinal direction better.

[0051] Meanwhile, the guiding wheel 222 rotates under the action of friction, and its friction is rolling friction, which can further avoid biting and jamming between the guiding side plate 12 and the guiding and rectifying component 22. Therefore, it ensures that the main cable saddle slides smoothly and without jamming during the jacking process.

[0052] Optionally, as Figure 8 shown, the guiding and rectifying component 22 further includes: a mounting plate 224, a mounting shaft 225, a connecting plate 226, a cover plate 227, a locking nut 228 and two ear plates 229.

[0053] As Figure 8 shown, one end of the mounting shaft 225 is connected to the plate surface of the mounting plate 224, and the two ear plates 229 are arranged in parallel and spaced on the plate surface of the mounting plate 224 away from the mounting shaft 225, and the guiding wheel 222 is rotatably mounted between the two ear plates 229.

[0054] By arranging two ear plates 229 on one side of the mounting plate 224, a mounting basis is provided for the guiding wheel 222, enabling the guiding wheel 222 to be rotatably mounted between the two ear plates 229 and realizing the rolling contact between the guiding wheel 222 and the guiding side plate 12.

[0055] As Figure 8As shown, the force - applying member 223 is a disc spring. The disc spring is sleeved outside the mounting shaft 225, and one end of the disc spring abuts against the mounting plate 224. The connecting plate 226 is sleeved outside the mounting shaft 225, and the other end of the disc spring abuts against the connecting plate 226. The other end of the mounting shaft 225 has a threaded section 2251. The cover plate 227 is sleeved outside the threaded section 2251, and the cover plate 227 abuts against the connecting plate 226. The connecting plate 226 is located between the cover plate 227 and the mounting plate 224. The locking nut 228 is sleeved outside the threaded section 2251 and is threadedly connected to the threaded section 2251. The locking nut 228 abuts against the cover plate 227.

[0056] In the embodiment of the present disclosure, the disc spring is sleeved outside the mounting shaft 225, and the two ends of the disc spring respectively abut against the connecting plate 226 and the mounting plate 224. And the connecting plate 226 is movably sleeved outside the mounting shaft 225. Therefore, when the guide wheel 222 is subjected to an extrusion force, the extrusion force is transmitted to the mounting plate 224 through the ear plate 229, causing the mounting plate 224 to move in the direction of the connecting plate 226. Since the distance between the mounting plate 224 and the connecting plate 226 is shortened, the disc spring will be compressed, so that the disc spring exerts a reverse elastic force on the mounting plate 224, prompting the mounting plate 224 to move back in the direction away from the connecting plate 226, that is, the guide wheel 222 will also push the guide side plate 12 back, thus achieving the purpose of active rectification during the jacking process of the main saddle, ensuring the coincidence degree of the main saddle along the preset center - line direction, and ensuring smoothness and no jamming during the jacking and sliding process of the main saddle.

[0057] Exemplarily, a threaded section 2251 is also provided at the end of the mounting shaft 225. The cover plate 227 is sleeved outside the threaded section 2251 and abuts against the sleeve plate through the locking nut 228. Since the cover plate 227 abuts against the connecting plate 226, by rotating the locking nut, it is possible to control the cover plate 227 to abut against the connecting plate 226 and move in the direction of the mounting plate 224, so as to reduce the distance between the connecting plate 226 and the mounting plate 224 and compress the disc spring, thereby adjusting the elastic force of the disc spring. That is to say, by rotating the locking nut, the pre - pressure exerted by the disc spring on the mounting plate 224 and the guide wheel 222 can be flexibly adjusted.

[0058] Figure 9 It is a schematic structural diagram of a connecting plate 226 provided by an embodiment of the present disclosure. As Figure 8 、 9 shown, the plate surface of the connecting plate 226 has a first through - hole 2261 and a second through - hole 2262 connected coaxially. The aperture of the first through - hole 2261 is larger than that of the second through - hole 2262. The first through - hole 2261 is located on the plate surface of the connecting plate 226 close to the mounting plate 224.

[0059] Exemplarily, as Figure 9As shown, the first through hole 2261 and the second through hole 2262 penetrate through the connecting plate 226, and the first through hole 2261 and the second through hole 2262 together form a stepped hole.

[0060] Figure 10 It is a partial structural schematic diagram of a guiding and deviation-correcting assembly 22 provided by an embodiment of the present disclosure. As Figure 10 shown, the guiding and deviation-correcting assembly 22 further includes a protection cylinder 230. The protection cylinder 230 is coaxially sleeved outside the mounting shaft 225, and one end of the protection cylinder 230 is connected to the mounting plate 224.

[0061] As Figure 8 shown, the inner diameter of the protection cylinder 230 is greater than or equal to the outer diameter of the disc spring, the outer diameter of the protection cylinder 230 is less than or equal to the aperture of the first through hole 2261, the aperture of the second through hole 2262 is greater than or equal to the diameter of the mounting shaft 225, and the mounting shaft 225 is inserted into the second through hole 2262.

[0062] By sleeving the protection cylinder 230 outside the disc spring, it can protect the disc spring from being interfered by impurities in the external environment, thereby preventing the disc spring from being stuck by foreign objects and affecting the elastic force exerted by the disc spring. At the same time, the outer diameter of the protection cylinder 230 is less than the aperture of the first through hole 2261, so that the protection cylinder 230 can also extend into the first through hole 2261.

[0063] Exemplarily, the length of the protection cylinder 230 is less than the length of the disc spring, and the length of the protection cylinder 230 can be equal to the length of the disc spring in the maximum compression state. In this way, when the disc spring is compressed to the limit state, the protection cylinder 230 will abut against the bottom surface of the first through hole 2261, thereby preventing the distance between the mounting plate 224 and the connecting plate 226 from being further shortened and preventing the disc spring from being damaged.

[0064] Optionally, as Figure 8 shown, the guiding and deviation-correcting assembly 22 further includes an adjusting ring 231. The adjusting ring 231 is sleeved outside the mounting shaft 225. One end of the adjusting ring 231 abuts against the bottom surface of the first through hole 2261, and the other end of the adjusting ring 231 abuts against the disc spring.

[0065] When a larger pre-pressure needs to be provided by the disc spring, an adjusting ring 231 can also be sleeved outside the mounting shaft 225 so that the adjusting ring 231 abuts against the connecting plate 226 and the disc spring, so that the disc spring can be further compressed, thereby providing a larger pre-pressure in the initial stage.

[0066] Exemplarily, the adjusting ring 231 can include a plurality of rings with different lengths. When the pre-pressure of the disc spring needs to be adjusted, rings with different lengths can be sleeved outside the mounting shaft 225, so as to adjust the degree of compression of the disc spring in the initial stage.

[0067] Optionally, as Figure 8As shown, the guiding and deviation-correcting assembly 22 further includes a spacer ring 232. The spacer ring 232 is sleeved outside the mounting shaft 225 and is clamped between the disc spring and the mounting plate 224.

[0068] Exemplarily, the spacer ring 232 can be a rubber pad, which can avoid direct contact between the disc spring and the mounting plate 224, thereby reducing the wear caused by contact between the disc spring and the mounting plate 224 and improving the service life of the disc spring and the mounting plate 224.

[0069] Optionally, as Figure 8 , 9 shown, the plate surface of the connecting plate 226 also has a mounting hole 2263. The connecting plate 226 is connected to the mounting vertical plate 221 by bolts passing through the mounting hole 2263.

[0070] Exemplarily, as Figure 9 shown, a plurality of mounting holes 2263 are provided on the plate surface of the connecting plate 226. The plurality of mounting holes 2263 are arranged circumferentially around the first through hole 2261. Each mounting hole 2263 is correspondingly provided with a bolt, and the bolt can pass through the mounting hole 2263 and be threadedly connected to the screw hole on the mounting vertical plate 221, thereby fixing the guiding wheel 222 and the disc spring on the mounting vertical plate 221, so that the guiding wheel 222 can stably abut against the guiding side plate 12.

[0071] Optionally, as Figure 8 shown, the guiding and deviation-correcting assembly 22 further includes: a wheel shaft 233 and an end cover 234. Both ends of the wheel shaft 233 are inserted into the through holes of the two ear plates 229. The guiding wheel 222 is sleeved outside the wheel shaft 233. The end cover 234 is press-fitted on the plate surface of one ear plate 229, and the end cover 234 is detachably connected to one end of the wheel shaft 233.

[0072] In the embodiment of the present disclosure, the cover plate 227 is connected to the wheel shaft 233, and the cover plate 227 is also connected to the ear plate 229. In this way, the cover plate 227 can be fixed in the through hole of the ear plate 229 to prevent the wheel shaft 233 from loosening. Among them, the wheel shaft 233 is used for sleeving the guiding wheel 222. Therefore, setting the cover plate 227 can make the guiding wheel 222 stably abut against the guiding side plate 12.

[0073] Exemplarily, as Figure 8 shown, the cover plate 227 and the plate surface of the ear plate 229 can be fixed by bolts. In this way, the wheel shaft 233 can be removed by disassembling the cover plate 227, which is convenient for disassembling and replacing the guiding wheel 222.

[0074] Exemplarily, as Figure 8As shown, the guiding and deviation correcting assembly 22 further includes a bushing 239. The bushing 239 is sleeved outside the wheel axle 233, and the guiding wheel 222 is sleeved outside the bushing 239. That is, a bushing 239 is further provided between the wheel axle 233 and the guiding wheel 222 to prevent the guiding wheel 222 and the wheel axle 233 from being easily damaged by means of the bushing 239.

[0075] Exemplarily, the guiding and deviation correcting assembly 22 may further be provided with a bearing. The bearing is arranged between the wheel axle 233 and the guiding wheel 222, so that the guiding wheel 222 can rotate relative to the wheel axle 233 more easily, reducing the wear between the wheel axle 233 and the guiding wheel 222.

[0076] Optionally, as Figure 2 shown, the lower bearing seat 20 further includes two baffles 25. The two baffles 25 are arranged in parallel at intervals on the surface of the lower bearing plate 21, and the upper bearing plate 11 is clamped between the two baffles 25.

[0077] In the embodiment of the present disclosure, two parallel baffles 25 are further provided on the surface of the lower bearing plate 21. The baffle 25 clamps the upper bearing plate 11 to guide and limit the upper bearing plate 11 by means of the baffle 25, so as to prevent the upper bearing plate 11 from sliding and deviating too much.

[0078] Optionally, the guiding and deviation correcting assembly 22 further includes: a proximity switch 235, an alarm and a controller. The proximity switch 235 and the alarm are both electrically connected to the controller.

[0079] As Figure 7 shown, the proximity switch 235 is located on the connecting plate 226. The proximity switch 235 is used to detect the distance information between the connecting plate 226 and the mounting plate 224. The controller is configured to control the alarm to generate an alarm signal based on the distance information detected by the proximity switch 235.

[0080] Exemplarily, the controller may be a Programmable Logic Controller (PLC). Instructions for performing operations such as logical operations, sequential control, timing, counting, and arithmetic operations are stored inside the PLC, and various types of devices are controlled through digital or analog inputs and outputs.

[0081] Exemplarily, the alarm may be a speaker or a flash lamp.

[0082] When the guiding wheel 222 is pressed against the compression disc spring, the mounting plate 224 will gradually approach the proximity switch 235, and the proximity switch 235 will detect the distance information between it and the mounting plate 224 in real time. When the distance information obtained by the controller exceeds the threshold, the controller will output an instruction to the alarm to control the alarm to send out an alarm message, thereby reminding the technician to observe the jacking situation of the main saddle in time and improving safety.

[0083] In some other implementation manners, the force applying member 223 may also be an annular airbag. The annular airbag is sleeved outside the mounting shaft 225, and the annular airbag is connected to an air inflation pump. When it is necessary to increase the force applied by the force applying member 223 to the guide wheel 222, the air pump can be controlled to inflate. When it is necessary to reduce the force applied by the force applying member 223 to the guide wheel 222, the air pump can be controlled to deflate. In this way, the force applied by the force applying member 223 to the guide wheel 222 can be controlled more precisely.

[0084] Figure 11 is a schematic structural diagram of another guiding and deviation correcting assembly 22 provided by an embodiment of the present disclosure. As Figure 11 shown, a plurality of lubricating sacs 236 are further clamped between the disc spring and the mounting plate 224. The lubricating sacs 236 are arranged at circumferential intervals around the mounting shaft 225. An oil absorbing sponge 237 is arranged in the lubricating sac 236, and lubricating oil is adsorbed in the oil absorbing sponge 237.

[0085] As Figure 11 shown, the mounting plate 224 has oil injection holes 2241 penetrating through the mounting plate 224. The oil injection holes 2241 correspond to the lubricating sacs 236 one by one. The surface of the lubricating sac 236 has oil discharge ports 238, and the oil discharge ports 238 are connected to the corresponding oil injection holes 2241.

[0086] In this way, when the guide wheel 222 is stressed and the disc spring is further compressed, the action of the disc spring on the lubricating sac 236 will also increase, so that the lubricating sac 236 and the oil absorbing sponge 237 in the lubricating sac 236 are further compressed. After the oil absorbing sponge 237 is compressed, lubricating oil is injected into the oil injection holes 2241 through the oil discharge ports 238. After the lubricating oil is discharged from the oil injection holes 2241, it will be sprayed on the guide wheel 222, the ear plate 229 and the shaft sleeve, thereby realizing the lubrication of the guide wheel 222 and preventing the guide wheel 222 from being easily damaged due to a large extrusion force.

[0087] An embodiment of the present disclosure provides a main cable saddle. As Figure 1 、 2 shown, the main cable saddle includes the jacking guiding device and the saddle body 30 as described above. The saddle body 30 is located on the surface of the upper bearing plate 11 away from the lower bearing plate 21, and the saddle body 30 is located between the two guiding side plates 12.

[0088] During the jacking operation of this main cable saddle, when the resultant jacking force deviating from the center line received by the main cable saddle increases and the tendency of the main cable saddle to deviate from the center line increases, the guide wheel 222 compresses the disc spring through the mounting plate 224, so that the disc spring generates compressive deformation, so that the guide wheel 222 can yield to the deviating direction, thereby avoiding the rigid extrusion between the guide wheel 222 and the main cable saddle.

[0089] Meanwhile, since the disc spring is restricted by the connecting plate 226 fixed on the lower bearing plate 21, a reverse elastic force is exerted on the guiding side plate 12 of the main saddle through the guiding wheel 222. Therefore, the main saddle can be pushed back towards the theoretical position of the center line of the main saddle jacking, thereby realizing the active rectification of the main saddle during the jacking process, ensuring the coincidence degree of the main saddle along the preset center line direction, and ensuring the smoothness and non-blocking of the main saddle during the jacking and sliding process.

[0090] Moreover, a proximity switch 235 is also provided between the connecting plate 226 and the mounting plate 224. When the main saddle deviates from the jacking center line and the guiding wheel 222 compresses the disc spring along the mounting shaft 225 and moves a certain distance towards the mounting vertical plate 221 through the mounting plate 224, the controller will control the alarm to emit an alarm signal based on the distance information detected by the proximity switch 235.

[0091] During the jacking process of the main saddle, when the resultant jacking force deviating from the center line acting on the main saddle is too large and causes the main saddle to deviate too much, when the compression deformation of the disc spring reaches the contact between the plate surface of the connecting plate 226 and the end face of the protection cylinder 230, the mounting plate 224 will no longer yield, forming a limit for the extreme position of the main saddle by the guiding and rectifying assembly 22, ensuring the safety during the jacking process.

[0092] The above is not any form of limitation to the present disclosure. Although the present disclosure has been disclosed as above through embodiments, it is not intended to limit the present disclosure. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes by using the above-disclosed technical content within the scope of the technical solution of the present disclosure. However, as long as it does not depart from the content of the technical solution of the present disclosure, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present disclosure still fall within the scope of the technical solution of the present disclosure.
