Description

Technical Field

[0001] This utility model relates to the field of inspection equipment technology, and in particular to a directional inspection device for bridge piers. Background Technology

[0002] Bridge piers are widely used; for example, they are essential for the construction of viaducts, high-speed railways, and large bridges. Therefore, the safety inspection of bridge piers involves multiple aspects, and their importance is self-evident.

[0003] Currently, the safety inspection of bridge piers mostly relies on manual inspection. Given the complex top environment of bridge piers (especially super high bridge piers), manual inspection poses significant safety hazards, has low inspection efficiency, and may result in missed inspections.

[0004] In addition, there are also methods of deploying inspection robots by suspending them with cranes or lowering them with simple ropes. However, this method is extremely susceptible to the influence of wind and rope swing when operating on the facade of bridge piers tens of meters high. It is difficult to accurately locate the starting point, which can easily lead to violent collisions between the robot and the surface of the bridge pier, damaging the robot or the surface of the bridge pier. In addition, there are also problems such as getting stuck or falling. Utility Model Content

[0005] This application provides a bridge pier orientation inspection device, which can provide a precise inspection track for a wall-climbing robot. The wall-climbing robot can move smoothly along the guide track for inspection by its own drive or auxiliary traction. It has high stability, can achieve high-precision starting positioning and accurate recovery, reduces the risk of swinging and collision, and is not easy to get stuck or fall.

[0006] This application provides a bridge pier directional inspection device, which uses a wall-climbing robot to inspect bridge piers. The top of the bridge pier is provided with a bridge deck, and the bridge deck and the bridge pier together form a bridge body. The bridge pier directional inspection device includes two quick-fixing seats, a retractable guide rail connected between the two quick-fixing seats, and a fall-prevention component that can move directionally along the retractable guide rail. The two quick-fixing seats are used to be fixed at intervals to the bottom of the bridge deck. The fall-prevention component includes a moving part, an upper rope, a fall arrestor, and a lower rope connected in sequence from top to bottom. The bottom of the lower rope is connected to the wall-climbing robot. The moving part cooperates with the retractable guide rail, and the wall-climbing robot is used to climb and inspect the surface of the bridge pier.

[0007] In one possible implementation, the quick-fixing seat is a magnetic seat, and the bottom of the quick-fixing seat is provided with a limiting ring. The limiting rings on the two quick-fixing seats cooperate to form a passage suitable for the retractable guide rail to pass through.

[0008] In one possible implementation, the take-up and release guide rail is a U-shaped guide rail. The bottom of the take-up and release guide rail is symmetrically provided with limiting plates along the extension direction of the take-up and release guide rail, and there is a gap between the symmetrically distributed limiting plates to form a limiting channel. The moving member includes a traveling arm that cooperates with the limiting channel and a moving body that cooperates with the U-shaped inner cavity of the take-up and release guide rail. The moving body is in sliding or rolling cooperation with the U-shaped inner cavity.

[0009] In one possible implementation, the moving body includes a connecting arm vertically connected to the walking arm and a set of walking wheels symmetrically arranged at both ends of the connecting arm, wherein the connecting arm extends along the extension direction of the retraction guide rail, and wherein the set of walking wheels includes an axle vertically connected to the connecting arm and guide wheels symmetrically distributed at both ends of the axle, with the guide wheels at both ends abutting against the top walls of the limiting plates on both sides.

[0010] In one possible implementation, a process groove is provided in the middle of the connecting arm, and the process groove extends along the extension direction of the take-up and take-down guide rail.

[0011] In one possible implementation, the two ends of the take-up and take-down guide rail are respectively connected to limit members for limiting the moving member and limiting the take-up and take-down guide rail within the passageway.

[0012] In one possible implementation, the limiting member is a locking rod that horizontally penetrates the front and rear side walls of the take-up and put-down guide rail and symmetrically protrudes from the front and rear side walls of the take-up and put-down guide rail, with a positioning ring fitted at one end of the locking rod.

[0013] Beneficial effects: Compared with the prior art, the pier orientation inspection device provided in this application is equipped with a quick-fix seat, a retractable guide rail, and a fall protection component. The fall protection component has a fall protection device connected to a wall-climbing robot via a lower rope. The retractable guide rail provides the wall-climbing robot with a precise inspection track and a retractable track, thereby achieving high-precision initial positioning and accurate retrieval of the wall-climbing robot. At the same time, the wall-climbing robot can move smoothly along the retractable guide rail for inspection by its own drive or with auxiliary traction, which can reduce the risk of swinging and collision, and is less likely to get stuck or fall, making the inspection more efficient and safer.

[0014] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] refer to Figures 1 to 6This application provides a bridge pier directional inspection device, which uses a wall-climbing robot to inspect bridge piers 11. The top of each bridge pier 11 has a bridge deck 12, and the bridge deck 12 and the bridge piers 11 together form a bridge body 10. The bridge pier directional inspection device includes two quick-fixing seats 20, a retractable guide rail 30 connecting the two quick-fixing seats 20, and a fall-prevention component 40 capable of directional movement along the retractable guide rail 30. The two quick-fixing seats 20 are used to fix the bottom of the bridge deck 12 at intervals. Preferably, the quick-fixing seats 20 are magnetic seats, such as electromagnetic / permanent magnet hybrid adsorption bases, which can quickly and easily... Stable adsorption to the bottom of the bridge deck 12, with high working efficiency and strong adsorption stability, wherein the anti-fall component 40 includes a moving part 41, an upper rope 42, an anti-fall device 43 and a lower rope 44 connected in sequence from top to bottom, wherein the bottom of the lower rope 44 is connected to a wall-climbing robot 50, wherein the wall-climbing robot 50 is used to climb the surface of the bridge pier 11 for inspection, wherein the moving part 41 cooperates with the retraction guide rail 30 to provide guidance during the inspection process of the wall-climbing robot 50, and can provide the wall-climbing robot 50 with precise initial positioning and precise path retrieval, so as to reduce or even eliminate the risk of the wall-climbing robot 50 swinging, colliding and other risks.

[0025] The working process is roughly as follows: First, attach two quick-fixing seats 20 to the bottom of the bridge deck 12, that is, the lower surface near the pier 11, one on each side of the pier 11. Then install the take-up and release guide rail 30. Next, install the moving part 41 into the take-up and release guide rail 30. Then connect the upper rope 42, the fall arrestor 43 and the lower rope 44 in sequence. Finally, connect the wall climbing robot 50.

[0026] Based on the positioning function of the retraction guide rail 30, the wall-climbing robot 50 can achieve fixed-point release and fixed-point retrieval. When the wall-climbing robot 50 patrols to a distance, it pulls the suspension rope to move the fall arrestor 43 along the retraction guide rail 20. As the wall-climbing robot 50 moves further and further down, the coiled rope inside the fall arrestor 43 will be pulled out. When the wall-climbing robot 50 moves from far to near, the pulled-out rope will be automatically retrieved. When the wall-climbing robot 50 unexpectedly loses pressure and falls, if the falling speed exceeds the threshold, the rope inside the fall arrestor 43 will be tightened instantly, triggering the mechanical locking action inside the fall arrestor 43, thus enabling the wall-climbing robot 50 to hover quickly. This allows for fully active safety protection and inspection operations without the need for external power. In addition, under the guidance of the deployment and take-up rail 30, whether the wall-climbing robot 50 moves by its own drive or with the assistance of traction, it can smoothly glide along the deployment and take-up rail 30 to the deployment edge, achieving high-precision initial positioning. During retrieval, the wall-climbing robot 50 accurately returns along the deployment and take-up rail 30.

[0027] Fall arrestor 43 is an existing device, also known as a speed differential device. It is a protective product that can quickly brake and lock falling objects within a limited distance. It is suitable for cargo hoisting, protecting the lives of ground operators and preventing damage to the hoisted workpiece.

[0028] In one embodiment, the bottom of the quick-fixing seat 20 is provided with a limiting ring 21, and the limiting rings 21 on the two quick-fixing seats 20 cooperate to form a passage suitable for the retractable guide rail 30 to pass through.

[0029] In one embodiment, the take-up and put-down guide rail 30 is a U-shaped guide rail, which can be quickly manufactured from U-shaped steel, making it easy to manufacture and low in cost. The bottom of the take-up and put-down guide rail 30 is symmetrically provided with limiting plates 31 along its extension direction, and the symmetrically distributed limiting plates 31 have gaps between them, forming a limiting channel 301. Correspondingly, the moving member 41 includes a traveling arm 411 that cooperates with the limiting channel 301 and a moving body 412 that cooperates with the U-shaped inner cavity 302 of the take-up and put-down guide rail 30. Simultaneously, the moving body 412 and the U-shaped inner cavity 302 are in sliding or rolling cooperation. Thus, the moving member 41 can be guided through the cooperation between the traveling arm 411 and the limiting channel 301, and the cooperation between the moving body 412 and the U-shaped inner cavity 302. The structure is simple and the guiding effect is good.

[0030] More preferably, the moving body 412 includes a connecting arm 4121 vertically connected to the walking arm 411 and a set of walking wheels symmetrically arranged at both ends of the connecting arm 4121. The connecting arm 4121 extends along the extension direction of the retractable guide rail 30. The set of walking wheels includes an axle 4122 vertically connected to the connecting arm 4121 and guide wheels 4123 symmetrically distributed at both ends of the axle 4122. The guide wheels 4123 at both ends abut against the top walls of the limiting plates 31 on both sides. Thus, based on the formation of a guiding fit, friction can be further reduced through a rolling fit, making the movement of the moving body 412 more convenient.

[0031] More preferably, a process groove 401 is provided in the middle of the connecting arm 4121, and the process groove 401 extends along the extension direction of the take-up and take-down guide rail 30. Thus, the design of the process groove 401 can reduce the overall weight on the one hand, and appropriately increase the structural strength and hardness of the connecting arm 4121 on the other hand.

[0032] In one embodiment, the two ends of the take-up and put-down guide rail 30 are respectively connected to limiting members 32, which are used to limit the moving member 41 within the take-up and put-down guide rail 30 by the limiting members 32, so as to prevent the limiting members 41 from moving and detaching from the take-up and put-down guide rail 30. At the same time, the limiting members 32 are also used to limit the take-up and put-down guide rail 30 within the passageway by the outer end, so as to prevent the take-up and put-down guide rail 30 from detaching from the quick fixation seat 20, making it safer to use.

[0033] In one embodiment, the limiting member 32 is a locking rod, wherein the locking rod horizontally penetrates the front and rear side walls of the take-up and put-down guide rail 30 and symmetrically protrudes from the front and rear side walls of the take-up and put-down guide rail 30, and a positioning ring 33 is sleeved on one end of the locking rod to ensure that the locking rod is inserted in place, so that both ends of the locking rod can be directly opposite the limiting ring 21.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
