Description

Technical Field

[0001] The present invention belongs to the technical field of bridge maintenance, and in particular relates to an integrated device for automatic detection and maintenance of bridge cables. Background Art

[0002] In bridge maintenance operations, the inspection and maintenance of bridge cables are key links to ensure the safe operation of bridges.

[0003] In the prior art, a hanging basket carrying operators is often used to inspect and repair bridge cables. After the operation is completed, the hanging basket needs to be stored in the storage device inside the main tower. During this process, in order to drain the rainwater remaining in the hanging basket, the conventional cleaning method is to directly rotate the hanging basket ninety degrees. However, this cleaning method has obvious defects. During the rotation of the hanging basket, the position of the steel cable is fixed, which can easily cause the steel cable to be excessively bent by ninety degrees, thereby generating greater stress inside the steel cable. Under long-term use, this stress concentration phenomenon will seriously affect the service life of the steel cable, increase the replacement frequency and maintenance cost of the steel cable, and there is also the risk of safety accidents caused by fatigue damage of the steel cable, which has an adverse impact on the safety and economy of bridge maintenance operations.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the problem of draining the rainwater remaining in the hanging basket, the conventional cleaning method is to directly rotate the hanging basket 90 degrees.

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0038] Example 1:

[0039] like Figures 1 to 9 As shown, an integrated equipment for automatic inspection and maintenance of bridge cables includes a main tower 1 provided with a cable 12 and a lifting and maintenance vehicle body 13 installed on the top of the main tower 1.

[0040] A storage slot 11 is provided inside the main tower 1 for storing the folded lift maintenance vehicle body 13, and a positioning cover 2 is rotatably installed inside the storage slot 11, which is adapted to the hanging basket 132 on the lift maintenance vehicle body 13. A swing arm 233 is installed at the rotation center of the positioning cover 2. The swing arm 233 is adapted to the top frame 234 installed at the bottom of the horizontal telescopic boom on the lift maintenance vehicle body 13. When the top frame 234 is shortened, it squeezes the swing arm 233 to drive the hanging basket 132 inside the positioning cover 2 to rotate for draining the water therefrom, and the steel cable 133 provided on the hanging basket 132 moves horizontally to reduce the bending degree of the steel cable 133.

[0041] A sealing plate 3 and a synchronization plate 33 are installed on the storage groove 11. The positioning cover 2 rotates to drive the synchronization plate 33 sliding on the side wall to move vertically, and the synchronization plate 33 moves vertically to drive the sealing plate 3 to control the opening and closing of the storage groove 11. A top seat 4 is installed on the synchronization plate 33, and the top seat 4 vertically corresponds to the counterweight block 131 on the lifting and maintenance vehicle body 13.

[0042] This structural design achieves multiple functions during the equipment storage process, including automatic basket drainage, cable protection, automatic sealing of the storage slot, and equipment center of gravity balance. Compared to traditional bridge maintenance equipment, this integrated design significantly reduces the frequency of manual maintenance, reduces the risk of equipment corrosion caused by residual rainwater, and extends the overall equipment life. It also improves the safety and reliability of the cables by reducing bending stress, thereby preventing accidents caused by cable damage during high-altitude operations.

[0043] like Figures 1 to 9 As shown, in a specific embodiment, L-shaped frames 134 are installed around the bottom plate of the lifting and maintenance vehicle body 13, and the bottom of the L-shaped frame 134 is installed on the bottom of the storage slot 11 by bolts, and a lifting column and a horizontally telescopic boom are installed inside the lifting and maintenance vehicle body 13, a winch assembly is provided at the output end of the boom, and one end of the winch assembly is connected to a steel cable 133, and the other end of the steel cable 133 is on the hanging basket 132, and a counterweight block 131 is installed at the other end of the boom, the lifting column, the horizontally telescopic boom and the winch assembly are all existing technologies, and their working principles are not repeated here.

[0044] Example 2:

[0045] The difference between the above embodiment and this embodiment is that: Figures 1 to 9As shown, the positioning cover 2 is provided with an inclined surface 213 on the relative inner surface, and the two inclined surfaces 213 are parallel to each other. The width of the interior of the positioning cover 2 is adapted to the width of the hanging basket 132. The bottom of the positioning cover 2 is provided with a plurality of pairs of through grooves 211 to reduce the weight of the positioning cover 2. A pair of guide plates 21 are installed on the top of the positioning cover 2, and the pair of guide plates 21 are V-shaped. Compared with the ordinary positioning structure, the design of the inclined surface 213, through grooves 211 and guide plates 21 of the positioning cover 2 greatly improves the drainage efficiency of the hanging basket, reduces the weight of the positioning cover itself, and reduces the energy consumption of the equipment operation. At the same time, the V-shaped guide plate 21 can play a precise guiding role when the hanging basket is stored, avoiding collision damage caused by inaccurate alignment, and effectively improving the operating efficiency and safety of the equipment.

[0046] like Figures 1 to 9 As shown, in a specific embodiment, a base 23 is installed at the bottom of the storage tank 11, and a connecting frame 22 is rotatably installed on the base 23. The connecting frame 22 is in a horizontal state, and the end of the connecting frame 22 is connected to the side wall of the positioning cover 2. A positioning seat 221 is installed at the bottom of the storage tank 11. The positioning seat 221 vertically corresponds to the connecting frame 22. A pair of positioning grooves 222 are provided on the positioning seat 221. The bottom of the connecting frame 22 is overlapped on the positioning grooves 222, and a notch 212 is provided on the positioning cover 2. Compared with the traditional positioning method, the cooperation between the connecting frame 22 and the positioning seat 221 can more accurately control the rotation angle and trajectory of the positioning cover 2, ensure the stability and reliability of the hanging basket draining process, effectively prevent the positioning cover 2 from offsetting when rotating, and ensure the normal operation of the equipment.

[0047] like Figures 1 to 9 As shown, a shaft 231 is rotatably mounted on the base 23, and the shaft 231 is connected to the rotation center of the connecting frame 22. A torsion spring 232 is sleeved on the shaft 231, and one end of the torsion spring 232 is clamped to the side wall of the base 23, and the other end of the torsion spring 232 is clamped to the connecting frame 22. The provision of the torsion spring 232 realizes the automatic reset function of the positioning cover 2. Compared with the manual reset method, it greatly improves the convenience of using the device, reduces manual operation steps, improves the degree of automation of the device, and reduces manual maintenance costs.

[0048] Example 3:

[0049] The difference between the above embodiment and this embodiment is that: Figures 1 to 9As shown, a pair of mutually parallel guide rails 31 are provided on the side walls of the storage tank 11. A pair of relatively sliding sealing plates 3 are slidably provided on the guide rails 31. A synchronization plate 33 is plugged into the outer wall of the lift and maintenance vehicle body 13. A fixing bracket 321 is mounted on the synchronization plate 33, and a positioning shaft 322 is mounted on the fixing bracket 321. A connecting arm 32 is rotatably mounted on the positioning shaft 322. The end of the connecting arm 32 is rotatably connected to the bottom of the sealing plate 3, and the connecting arm 32 is in an inclined state. Compared with traditional sealing structures, the coordinated design of the guide rails 31 and the sealing plate 3 realizes the automatic sealing function of the storage tank 11, effectively preventing the entry of impurities such as dust and rainwater from the outside, providing a good protective environment for the lift and maintenance vehicle body 13, extending the service life of the equipment, and reducing the failure rate of the equipment due to erosion by the external environment.

[0050] like Figures 1 to 9 As shown, in a specific embodiment, a limit seat 331 is installed around the storage slot 11, and the bottom of the synchronization plate 33 is overlapped on the limit seat 331. A limit rod 332 is movably connected to the limit seat 331. The limit rod 332 is movably connected to the synchronization plate 33. A limit plate 333 is installed on the top of the limit rod 332. A limit spring 334 is sleeved on the outer wall of the limit rod 332. One end of the limit spring 334 is clamped to the limit plate 333, and the other end of the limit spring 334 is clamped to the synchronization plate 33. Compared with a design without limit, the setting of the limit structure provides precise limit for the movement of the synchronization plate 33, improves the stability and reliability of equipment operation, and reduces equipment maintenance costs.

[0051] like Figures 1 to 9 As shown, further, a U-shaped groove 335 is provided at one end of the sealing plate 3, and a rocker arm 341 is slidably provided on the U-shaped groove 335. The rotation center of the rocker arm 341 is interconnected with the rotation center of the swing arm 233. A synchronization shaft 34 is installed at the end of the clamping shaft 231. The end of the synchronization shaft 34 is interconnected with the rotation center of the rocker arm 341. The end of the rocker arm 341 is interconnected with the positioning cover 2. The side wall of the rocker arm 341 is provided with a strip groove 342. A slide rod 343 is slidably provided on the strip groove 342. The end of the slide rod 343 is interconnected with the side wall of the synchronization plate 33. This transmission structure realizes the linkage function between the rotation of the positioning cover 2 and the sealing of the storage groove 11. Compared with the independent operation mode, it simplifies the equipment operation process, improves the degree of equipment automation, reduces energy loss during equipment operation, and improves the overall operating efficiency of the equipment.

[0052] The implementation principle of the bridge cable automatic detection and maintenance integrated equipment of the present invention is as follows:

[0053] When carrying out inspection and maintenance in rainy weather, the operator can start the lifting and maintenance vehicle body 13. The columns inside the lifting and maintenance vehicle body 13 drive the entire vehicle body to rise along the main tower 1, and finally the basket 132 is moved out of the storage slot 11. At this time, the horizontal telescopic arm is extended to send the basket 132 to the vicinity of the cable 12, and the winch assembly controls the steel cable 133 to adjust the vertical position of the basket 132, so that the operator can inspect and repair the cable 12 in the basket 132.

[0054] When the operation is completed or the equipment needs to be stored, the horizontal telescopic boom retracts, driving the hanging basket 132 toward the main tower 1 until the hanging basket 132 is directly above the storage slot 11. At this time, the operator activates the column to drive the entire lifting and maintenance vehicle body 13 to fold and store it into the storage slot 11.

[0055] When the lift and maintenance vehicle body 13 is completely stored in the storage slot 11, the top frame 234 on the boom moves to the left side of the swing arm 233. The boom of the lift and maintenance vehicle body 13 is then retracted, and the boom drives the top frame 234 to move horizontally, thereby squeezing the swing arm 233 as a whole. Since the swing arm 233 is connected to the rotation center of the positioning cover 2, under the squeezing action of the top frame 234, the swing arm 233 rotates around the rotation center, thereby driving the positioning cover 2 to rotate synchronously. The inclined surface 213 on the relatively inner side of the positioning cover 2, the notch 212 at the bottom, and the through groove 211 play a key role in this process. When the positioning cover 2 rotates, the hanging basket 132 inside it flips over accordingly. Under the action of gravity, the remaining rainwater quickly flows along the inclined surface 213 to the notch 212 or through groove 211 for discharge, achieving efficient drainage of the hanging basket 132 and preventing residual rainwater from corroding equipment components. At the same time, the through groove 211 reduces the weight of the positioning cover 2 itself, reducing the overall load on the equipment. The connecting frame 22 and the positioning seat 221 at the bottom of the storage tank 11 cooperate with each other to play a limiting role when the positioning cover 2 rotates, ensuring the accuracy of its rotation angle and trajectory, and ensuring that the entire draining process is stable and reliable.

[0056] In the process of the upper arm of the lifting and maintenance vehicle body 13 being retracted to drive the hanging basket to rotate, unlike the general cleaning method of directly rotating the hanging basket ninety degrees (in the conventional method, the position of the steel cable remains unchanged, which easily causes the steel cable to bend ninety degrees, generating greater stress and affecting the life of the steel cable), when the upper arm of the lifting and maintenance vehicle body 13 is retracted, it will also drive the steel cable 133 to move to the right, thereby making the steel cable 133 and the hanging basket 132 always maintain a reasonable relative angle, avoiding the formation of an excessively large angle, effectively reducing the stress concentration caused by excessive bending of the steel cable, and reducing the degree of wear of the steel cable.

[0057] During the rotation of the swing arm 233, the torsion spring 232 on the swing arm 233 is twisted synchronously, and the clamping shaft 231 provides stable support for the rotation of the positioning cover 2. The torsion spring 232 stores elastic potential energy to facilitate later reset. When the top frame 234 no longer squeezes the swing arm 233, the torsion spring 232 releases elastic potential energy, driving the positioning cover 2 to automatically reset without manual operation, thereby improving the convenience of equipment use. When the swing arm 233 and the positioning cover 2 rotate, the rocker arm 341 on the positioning cover 2 rotates synchronously. When the rocker arm 341 rotates, the slide bar 343 in the side wall strip groove 342 will slide in the groove. Since the end of the slide bar 343 is connected to the side wall of the synchronization plate 33, it drives the synchronization plate 33 to move vertically on the guide rail 31.

[0058] The guide rails 31 on the side walls of the storage tank 11 provide precise guidance for the sliding movement of the sealing plate 3. As the synchronous plate 33 moves, its upper mounting bracket 321, via the connecting arm 32, drives the sealing plate 3 to slide relative to the guide rails 31, gradually closing the sealing plate 3 and sealing the storage tank 11. The guide rails 31 ensure the stability and tightness of the sealing plate 3's movement, effectively preventing dust, rainwater, and other impurities from entering the storage tank 11 and providing a good protective environment for the lift truck body 13 housed therein. Furthermore, the limiting structure surrounding the storage tank 11, consisting of a limiting seat 331, limiting rod 332, limiting plate 333, and limiting spring 334, provides precise positioning and cushioning for the movement of the synchronous plate 33. The limiting seat 331 provides support and initial positioning for the synchronous plate 33, the limiting rod 332 restricts its movement, and the limiting spring 334 acts as a buffer during movement, preventing severe vibration or collisions caused by inertia or external impact. When the positioning cover 2 is reset, the limit spring 334 pushes the synchronization plate 33 back to its original position, ensuring that all equipment components can accurately return to their initial positions. As the synchronization plate 33 moves vertically, the top seat 4 also moves with it. The top seat 4 moves to the bottom of the counterweight block 131 on the lift and maintenance vehicle body 13, supporting the counterweight block 131, balancing the center of gravity of the equipment and ensuring stable storage.
