Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and more specifically, to a pier-crossing moving device. Background Technology

[0002] In recent years, with the rapid development of road networks, bridges, as key nodes in transportation networks, have become increasingly important for inspection and reinforcement. Regular inspections can detect structural damage to bridges (such as cracks and foundation settlement), allowing for timely assessment of their safety and ensuring healthy operation. Bridge inspection and reinforcement are crucial technical supports for ensuring road network safety and promoting sustainable development. Conventional bridge maintenance and reinforcement on land involves erecting a full-span scaffolding platform, while on water, suspended platforms or bridge inspection vehicles are used. Full-span scaffolding construction is time-consuming, requires a large amount of scaffolding materials, has a long construction cycle, and increases construction costs. Suspended platform operations are limited in scope due to the platform's immobility, resulting in limited operating space, inconvenience, and time-consuming and material-intensive movements, leading to low efficiency. Bridge inspection vehicles are also expensive.

[0003] The existing patent application number is 202322553030.2, entitled "A Mobile Operating Platform for Full-Section Construction of Large-Span Waterborne Beam Bottom with Through-Hole Capability." It discloses that "the operating platform includes a platform body, upper and lower channels, and a load-bearing moving system. The platform body includes two detachably connected platform split structures. The load-bearing moving system includes multiple winches and sliding devices. The sliding devices can slide back and forth on the upper surface of the steel box girder. Each winch can be detachably connected to the platform body and the upper and lower channels, and can drive the platform body and the upper and lower channels to move. This utility model operating platform has good performance, high safety and stability, can move through holes, is convenient to move, and can effectively improve safety in production. It can be applied and promoted to future bridge construction projects." However, the use of multiple winches to move the platform body increases the demand for additional winches.

[0029] This embodiment discloses a cross-pier moving device, such as Figure 1-4 As shown, it includes:

[0030] The cross-pier moving device 1 is located on bridge 2;

[0031] The cross-pier moving device 1 includes a walking component 10, a lifting component 20, a working component 30, and a supporting component 40;

[0032] The walking component 10 is suspended above the bridge deck of the bridge 2. The walking component 10 rolls in contact with the supporting guardrail 3 on the bridge 2. The walking component 10 can move relative to the supporting guardrail 3. The lifting component 20 is installed on the walking component 10 and is located on one side of the supporting guardrail 3. The walking component 10 is connected to one end of the support component 40. The support component 40 is located on the other side of the supporting guardrail 3 and there is a gap between the support component 40 and the supporting guardrail 3. The other end of the support component 40 is movably connected to one side of the working component 30. The working component 30 can rotate relative to the support component 40. The traction rope 22 in the lifting component 20 is connected to the other side of the working component 30. The working component 30 is located below the bridge 2. The supporting component 40, the traction rope 22, and the working component 30 form a triangular structure.

[0033] In this embodiment, the pier-crossing moving device 1 is erected on the bridge 2. Specifically, the walking component 10 is erected on the supporting guardrail 3. One end of the walking component 10 is in rolling contact with the supporting guardrail 3, allowing it to roll on the surface of the supporting guardrail 3. The other end of the walking component 10 is suspended above the bridge deck of the bridge 2 and is used for the installation of the lifting component 20. The walking component 10 carries the lifting component 20, which is located on one side of the supporting guardrail 3. One end of the walking component 10 is connected to the support component 40, which is located on the other side of the supporting guardrail 3. The support component 40 and the supporting guardrail 3 are spaced apart, meaning the support component 40 does not directly contact the supporting guardrail 3, reducing friction between the pier-crossing moving device 1 and the guardrail. This creates a connection between the support component 40 and the lifting component. The support components 20 are located on opposite sides of the supporting guardrail 3. The support component 40 has a length extending below the bridge 2. The other end of the support component 40 is movably connected to one side of the working component 30. The working component 30 is located below the bridge 2. The traction rope 22 in the lifting component 20 is connected to the other side of the working component 30. The lifting component 20 retracts or releases the traction rope 22, allowing the working component 30 to rotate relative to the support component 40. When the bridge 2 needs to be inspected, maintained, or repaired, the lifting component 20 controls the length of the traction rope 22 to be maintained so that the worker can be on the working component 30. At the same time, the worker can work on the working component 30 while moving the cross-pier moving device 1 through the walking component 10. The cross-pier moving device 1 can be moved by pulling or pushing. When the moving device 1 encounters a pier column 4 that obstructs the progress of the working component 30, the worker leaves the working component 30. The lifting component 20 releases the traction rope 22, causing the working component 30 to rotate relative to the support component 40. This increases the angle between the working component 30 and the support component 40, potentially reaching 180 degrees. The working component 30 and the support component 40 are then aligned in the same direction of gravity, with the working component 30 suspended below the support component 40. This allows the working component 30 to avoid the pier column 4, enabling the moving device 1 to continue moving forward. When work is needed, the lifting component 20 tightens the traction rope 22, causing the working component 30 to rotate relative to the support component 40 until it is perpendicular to the support component 40, allowing the worker to stand on it. At this point, the tightening of the traction rope 22 is stopped, and it remains tightened to ensure the worker's safety while working on the working component 30.

[0034] In this embodiment, as Figure 1As shown, the walking component 10 can both support the lifting component 20 and drive the lifting component 20 to move, thereby driving the support component 40 and the working component 30 to move. The lifting component 20 controls the traction rope 22 to adjust the rotation of the working component 30, ensuring that the working component 30 avoids the bridge pier 4 when moving along the length of the bridge. This embodiment of the pier-crossing moving device 1 not only moves but also self-adjusts to avoid obstacles such as the bridge pier 4. This pier-crossing moving device 1 is flexible in use, simple in structure, and readily available, making it suitable for widespread application.

[0035] Preferably, the length of the support component 40 extending below the bridge 2 can be set according to the vertical height of the bridge 2, that is, the length of the support component 40 extending below the bridge 2 is greater than the vertical height of the bridge 2. This not only allows workers to work on the working component 30, but also ensures that the cross-pier moving device 1 can move without obstruction, or with minimal obstruction. This eliminates the need for frequent adjustments to the rotation of the working component 30 relative to the support component 40.

[0036] In some embodiments, the work platform has a counterweight to ensure relative balance between the work component 30 and the lifting component 20.

[0037] According to one embodiment of the present invention, such as Figure 1-4 As shown, the cross-pier moving device 1 includes a first working state and a second working state. The first working state includes: the included angle between the working component 30 and the traction rope 22 is equal to a set value, and the traction rope 22 has a first length from the lifting component 20 to the working component 30.

[0038] The second working state includes: the traction rope 22 has a second length from the lifting component 20 to the working component 30, the second length is greater than the first length, and the angle between the working component 30 and the traction rope 22 is less than the set value.

[0039] In this embodiment, the first working state is when the worker can carry out construction on the working component 30, and the second working state is when the worker has left the working component 30. At this time, the working component 30 is in a state of avoiding the bridge pier column 4, so that the cross-pier moving device 1 can move without obstacles.

[0040] In some embodiments, the set value is the angle between the working component 30 and the support component 40 that ensures the worker is working on the working component 30. Specifically, the horizontal plane of the platform on which the worker works on the working component 30 is perpendicular to the direction of gravity of the support component 40. Preferably, the set value is 90 degrees.

[0041] According to one embodiment of the present invention, such as Figure 1As shown, there are two pier moving devices 1. The two pier moving devices 1 are located on both sides of the bridge 2 along the extension direction of the bridge 2, and the two pier moving devices 1 are connected to each other through the working component 30.

[0042] In this embodiment, the installation of two cross-pier moving devices 1 facilitates workers to carry out comprehensive maintenance and other work on the bridge 2. On the other hand, the interconnection of the two cross-pier moving devices 1 increases the stability of the cross-pier moving devices 1, further ensuring that workers can work in a safe environment.

[0043] In some embodiments, the working component is provided with a fourth connecting part 35, and the fourth connecting parts 35 of the two cross-pier moving devices 1 are connected to each other by bolts or other connecting parts.

[0044] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the walking assembly 10 includes a support frame 11, a support platform 12, and a first roller 13. The first roller 13 is rotatably connected to the support frame 11 and contacts the support railing 3. The first roller 13 is movable relative to the support railing 3. The support platform 12 is connected to the support frame 11 and is suspended on one side of the support railing 3. The lifting assembly 20 is located on the support platform 12.

[0045] In this embodiment, the support platform 12 is used to install the lifting assembly 20. The lifting assembly 20 is suspended above the bridge deck on one side of the support railing 3 via the support platform 12, so that the support railing 3 serves as a balancing support point between the working assembly 30 and the lifting assembly 20, reducing the lateral load on the support railing 3 from the lifting assembly 20. The support frame 11 contacts the support railing 3 via the first roller 13. When the first roller 13 rolls, it drives the lifting assembly 20 to move through the support frame.

[0046] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the support frame 11 is L-shaped. The first end of the support frame 11 is located on one side of the support railing 3. The first end of the support frame 11 is connected to the support platform 12. The first roller 13 is rotatably connected to the second end of the support frame 11. The first roller 13 contacts the side of the support railing 3. The support assembly 40 is connected to the first end of the support frame 11.

[0047] The walking assembly 10 also includes a second roller 14, which is rotatably connected to the second end of the support frame 11 and contacts the top of the support guardrail 3.

[0048] In this embodiment, the first roller 13 contacts the side of the supporting guardrail 3, and the second roller 14 contacts the top of the supporting guardrail 3, increasing the ability of the cross-pier moving device 1 to move easily.

[0049] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, at least two of the first roller 13 and the second roller 14 are provided.

[0050] In this embodiment, at least two first rollers 13 and second rollers 14 are provided, making it easy for the pier-crossing moving device 1 to move forward.

[0051] In some embodiments, the number of second rollers 14 is greater than the number of first rollers 13. The second rollers 14 not only drive the lifting assembly 20 to move, but also serve as indirect support points for balancing the heat exchange lifting assembly 20 between the working assembly 30 and the working assembly 30. Therefore, while considering the ease of movement of the second rollers 14, it is also ensured that the second rollers 14 have suitable support performance. Multiple second rollers 14 cooperate to support and improve the structural and operational stability of the pier moving device 1.

[0052] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the lifting assembly 20 includes a winch 21 and a traction rope 22. The winch 21 is connected to the traction rope 22, and the traction rope 22 is connected to the working assembly 30.

[0053] In this embodiment, the winch 21 is mounted on the moving component. Specifically, the winch 21 is mounted on the support platform 12. The winch 21 is connected to the traction rope 22. The winch 21 stores the traction rope 22. The winch 21 is connected to the working component 30 through the traction rope 22. The winch 21 controls the retraction and release of the traction rope 22 to adjust the angle between the working component 30 and the support component 40.

[0054] According to one embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the working component 30 includes a working platform 31, a working guardrail 32, a first connecting part 33, and a second connecting part 34. The working guardrail 32 is located around the working platform 31. The first connecting part 33 is located on the side of the working platform 31 near the support component 40 and is rotatably connected to the support component 40. The second connecting part 34 is located on the side away from the support component 40. The traction rope 22 is connected to the second connecting part 34.

[0055] In this embodiment, the work platform 31 provides a working environment for workers, the work railing 32 ensures a safe working environment for workers, the first connecting part 33 is rotatably connected to the support component 40, and the second connecting part 34 is connected to the traction rope 22. When the traction rope 22 is released, the work component 30 rotates relative to the support component as the traction rope 22 is released.

[0056] According to one embodiment of the present invention Figure 1-3 As shown, the support assembly 40 includes a first support rod 41, a second support rod 42, and a third connecting part 43. One end of the first support rod 41 is connected to the walking assembly 10, and the third connecting part 43 is disposed at the other end of the first support rod 41. The first support rod 41 is rotatably connected to the first connecting part 33 through the third connecting part 43. One end of the second support rod 42 is detachably connected to the first support rod 41, and the other end of the second support rod 42 is detachably connected to the second connecting part 34.

[0057] In this embodiment, there are two first support rods 41, two second support rods 42, and two third connecting parts 43. The second support rod 42 is connected to the first support rod 41, and the second support rod 42 is connected to the second connecting part 34 on the work platform 31, so that the second support rod 42, the first support rod 41 and the work platform 31 form a triangular structure, which increases the stability of the structure. When the pier-crossing moving device 1 needs to be moved and encounters the pier column 4, the second connecting rod is disconnected from the second connecting part 34 on the working platform 31. During this process, the second support rod 42 and the first connecting rod can be detached or kept connected. If the pier column 4 affects the forward movement of the second support rod 42, the second connecting rod should be disconnected from the first support rod 41, the traction rope 22 is released, and the working platform 31 rotates relative to the first support rod 41 until the working platform 31 avoids the pier column 4. When it avoids the pier column 4, the traction rope 22 is retracted, and the working platform 31 rotates relative to the first support rod 41 to the first working state. The angle between the platform surface of the working platform 31 and the vertical direction of the first support rod 41 is 90 degrees. The retraction of the traction rope 22 is stopped, and the length of the traction rope 22 remains unchanged at this time. The second support rod 42 is then reconnected to the second connecting part 34.

[0058] In some embodiments, such as Figure 3 As shown, the support assembly 40 also includes multiple crossbars 46, which are connected to two first support rods 41 to form a ladder, allowing workers to access the work platform 31 via the ladder.

[0059] According to one embodiment of the present invention, such as Figure 1 , 2 and Figure 4As shown, the support assembly 40 includes a first steering pulley 44 and a second steering pulley 45. The first steering pulley 44 is disposed at one end of the first support rod 41 near the walking assembly 10, and the second steering pulley 45 is disposed on the first support rod 41 near the second support rod 42. The traction rope 22 is connected to the first connecting part 33 in sequence along the first steering pulley 44 and the second steering pulley 45.

[0060] In this embodiment, the arrangement of the first steering pulley 44 and the second steering pulley 45 facilitates the placement of the traction rope 22 in a suitable space.

[0061] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
