[0008] Optionally, the first carrier is rotatably mounted on the first traveling structure, and the rotation axis of the first carrier has an angle with the extension direction of the arm.

[0014] The technical solution provided in this application has the following advantages compared with the prior art:

[0015] The technical solution provided in this application includes a track-laying device comprising a boom, a traveling mechanism, and a hoisting mechanism. During track-laying operations, the track-laying device moves to the erection position via the traveling mechanism. Then, the hoisting mechanism grabs the object to be laid and, by moving along the boom, hoists the object to the target position to complete the track-laying operation. Here, at least one of the first and second traveling components in the traveling mechanism can move relative to the boom, allowing the distance between the first and second traveling components to be adjustable; that is, the railway gauge of the track-laying device can be adjusted. Thus, during track-laying operations, the track-laying device can adjust the railway gauge according to actual needs. For example, during the movement of the track-laying device, its curve-passing capability can be improved by increasing the railway gauge; after the track-laying device reaches the erection position, its long-distance erection capability can be improved by decreasing the railway gauge. Compared to related technologies where the railway gauge of the track-laying device is not adjustable, in this embodiment, the track-laying device can adjust the railway gauge according to actual needs to adapt to curved tracks with different curvatures and track-laying operations of different distances, improving the flexibility of the track-laying device. In this way, there is no need to replace the scaffolding device during the scaffolding laying operation, which reduces construction costs and scaffolding laying time. Attached Figure Description

Detailed Implementation

[0034] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0036] With the continuous growth of railway operating mileage and the increasing service life of bridges, the need for railway bridge maintenance is becoming increasingly prominent. Statistics show that approximately 40% of railway bridges nationwide have been in use for more than 30 years, and these bridges generally suffer from varying degrees of damage, making bridge replacement work particularly urgent.

[0037] In bridge construction, the bridge-laying device is the core component for completing the erection work. In related technologies, a bridge-laying device typically includes a boom, a traveling mechanism, and a hoisting mechanism. During the erection operation, the bridge-laying device travels to the erection location via the traveling mechanism, and then the hoisting mechanism grabs the object to be laid (such as beams, piers, etc.) for the erection work. However, in practice, bridge-laying devices suffer from poor operational flexibility.

[0038] Research into the aforementioned issues revealed that the traveling mechanism of a track-laying device typically comprises a front traveling component and a rear traveling component. In this device, the horizontal distance between the centerlines of the front and rear traveling components is called the railway gauge, which is directly related to the track-laying device's curve-passing capacity and erection distance. However, in related technologies, the railway gauge of track-laying devices is usually a fixed value, making it impossible to adjust the device's curve-passing capacity and erection distance, thus hindering its adaptability to curved tracks with varying curvatures and track-laying operations of different distances. Consequently, frequent replacement of the track-laying device is required during track-laying operations, increasing construction costs and extending the operation time.

[0039] Regarding the relationship between railway gauge, curve-passing capacity, and long-distance erection capability, it's important to explain in detail that when the track-laying equipment traverses a curved track, the traveling mechanism must always maintain tangential contact with the track. When the track-laying equipment is large, its inherent rigidity makes it difficult to bend with the track. Therefore, within its gauge range, it essentially acts as a "chord" intersecting the curved track, with the front and rear traveling components located at either end of this "chord." Thus, the larger the railway gauge, the longer the span between the front and rear traveling components, and the smaller the angle between the "chord" formed by the track-laying equipment on the curve and the curved track, thereby reducing the risk of interference between the track-laying equipment and the track. Conversely, during erection operations, a smaller railway gauge allows for a longer cantilever section of the boom, thus increasing the track-laying equipment's long-distance erection capability.

[0040] To solve the above problems, refer to Figure 1 , Figure 2 and Figure 3 This application provides a scaffolding device, which includes a boom 1, a traveling mechanism 2, and a hoisting mechanism 3. The traveling mechanism 2 includes a first traveling component 21 and a second traveling component 22. Along the extension direction of the boom 1, the first traveling component 21 and the second traveling component 22 are spaced apart on the boom 1, and at least one of the first traveling component 21 and the second traveling component 22 can move relative to the boom 1 to adjust the distance between the first traveling component 21 and the second traveling component 22. Along the extension direction of the boom 1, the hoisting mechanism 3 is movably disposed on the boom 1.

[0041] In this embodiment, the function of the boom 1 is to provide structural support for the laying device. Here, the structural design of the boom 1 has various possibilities. For example, the boom 1 can be a beam structure or a frame structure. This embodiment does not limit the specific design of the boom 1.

[0042] In this embodiment, the first walking component 21 and the second walking component 22 can drive the scaffolding device to move. Here, the structural forms of the first walking component 21 and the second walking component 22 are various. For example, the first walking component 21 and the second walking component 22 can be wheeled walking components, tracked walking components, or outrigger walking components. This embodiment does not limit the specific form of the walking component 21.

[0043] In this embodiment, the connection between the first walking component 21 and the second walking component 22 and the robotic arm 1 can be varied. For example, both the first walking component 21 and the second walking component 22 can be movably connected to the robotic arm 1; or only the first walking component 21 can be movably connected to the robotic arm 1; or only the second walking component 22 can be movably connected to the robotic arm 1. This embodiment does not limit the connection in this respect.

[0044] In this embodiment, the function of the hoisting mechanism 3 is to grab the object to be laid. Here, the structural design of the hoisting mechanism 3 has various possibilities. For example, the hoisting mechanism 3 may include a lifting beam trolley and a lifting block trolley; or, the hoisting mechanism 3 may only include a lifting beam trolley; or, the hoisting mechanism 3 may only include a lifting block trolley. This embodiment does not limit the scope of the application.

[0045] In the technical solution provided in this application embodiment, the track laying device includes a boom 1, a traveling mechanism 2, and a hoisting mechanism 3. During track laying operations, the track laying device moves to the erection position via the traveling mechanism 2. Then, the hoisting mechanism 3 grabs the object to be laid and, by moving on the boom 1, hoists the object to be laid to the target position to complete the track laying operation. Here, at least one of the first traveling component 21 and the second traveling component 22 in the traveling mechanism 2 can move relative to the boom 1, so that the distance between the first traveling component 21 and the second traveling component 22 can be adjusted, that is, the railway gauge of the track laying device can be adjusted. Thus, during track laying operations, the track laying device can adjust the railway gauge according to actual needs. For example, during the travel of the track laying device, its curve-passing capacity can be improved by increasing the railway gauge; after the track laying device has traveled to the erection position, its long-distance erection capacity can be improved by decreasing the railway gauge.

[0046] Compared to related technologies where the railway gauge of the track-laying device is not adjustable, in this embodiment, the track-laying device can adjust the railway gauge according to actual needs to adapt to curved tracks with different curvatures and track-laying operations of different distances, thus improving the flexibility of the track-laying device. This eliminates the need to replace the track-laying device during track-laying operations, reducing construction costs and operation time.

[0047] Reference Figure 1 and Figure 2In this embodiment of the application, at least one of the first walking assembly 21 and the second walking assembly 22 includes a first walking structure 211 and a first support member 212. The first support member 212 is disposed on the first walking structure 211 and is movably connected to the arm 1 along the extension direction of the arm 1. Here, the first support member 212 can serve as an intermediate force transmission member, distributing the pressure of the arm 1 evenly to the walking structure, thereby avoiding local stress concentration.

[0048] It should be noted that both the first walking component 21 and the second walking component 22 may include the first walking structure 211 and the first support member 212. Alternatively, only the first walking component 21 may include the first walking structure 211 and the first support member 212; or only the second walking component 22 may include the first walking structure 211 and the first support member 212. This application does not limit the specific implementation of these embodiments.

[0049] Reference Figure 1 and Figure 2 In this embodiment, the walking mechanism 2 further includes an adjustment structure 23, which is disposed between the first walking structure 211 and the first support member 212 to adjust the relative position between them. Thus, the walking mechanism 2 can adjust the relative position between the first walking structure 211 and the first support member 212 via the adjustment structure 23, thereby changing the posture of the scaffolding device. Consequently, when the scaffolding device passes through narrow passages, its ability to pass through can be improved by changing its posture.

[0050] In this embodiment of the application, the structural design of the adjustment structure 23 can be varied. For example, the adjustment structure 23 may include a worm gear structure, which is disposed between the first traveling structure 211 and the first carrier 212 to adjust the relative position between the first traveling structure 211 and the first carrier 212.

[0051] Reference Figure 4 and Figure 6 In this embodiment, the adjustment structure 23 includes a telescopic power member 231. The telescopic end of the telescopic power member 231 is connected to the first support member 212 to drive the first support member 212 to move along the telescopic direction of the telescopic power member 231. The telescopic direction of the telescopic power member 231 has an angle with the extension direction of the arm 1. Thus, along the telescopic direction of the telescopic power member 231, the telescopic power member 231 can drive the first support member 212 to adjust its position, thereby changing the size of the laying frame device in the telescopic direction of the telescopic power member 231.

[0052] It should be noted that the angle between the telescopic power member 231 and the extension direction of the arm 1 can be various. For example, the angle between the telescopic power member 231 and the extension direction of the arm 1 can be 60°, 90°, or 120°. This application embodiment does not limit this.

[0053] Reference Figure 5 and Figure 7 In this embodiment, the first carrier 212 is rotatably mounted on the first traveling structure 211. The rotation axis of the first carrier 212 has an angle with the extension direction of the arm 1. The adjustment structure 23 also includes a rotational power member 232, the power end of which is connected to the first carrier 212 to drive the first carrier 212 to rotate relative to the first traveling structure 211. Thus, the rotational power member 232 can drive the first carrier 212 to rotate relative to the first traveling structure 211, thereby adjusting the angle between the first carrier 212 and the first traveling structure 211. For example, refer to... Figure 4 and Figure 5 Before the track laying device passes through tunnel 9, the rotating power component 232 can adjust the angle between the first bearing component 212 and the first traveling structure 211 to an acute angle, thereby reducing the cross-sectional area of ​​the track laying device and improving its tunnel 9 passage capacity. (Refer to...) Figure 6 and Figure 7 After the paving device passes through tunnel 9, the rotating power component 232 can adjust the angle between the first bearing component 212 and the first traveling structure 211 to a right angle so that the paving device can continue to carry out paving operations.

[0054] It should be noted that the angle between the rotation axis of the first support member 212 and the extension direction of the arm 1 can be various. For example, the angle between the rotation axis of the first support member 212 and the extension direction of the arm 1 can be 60°, 90°, or 120°. This application embodiment does not limit this.

[0055] In this embodiment of the application, there are multiple possibilities for the connection between the first support member 212 and the robot arm 1. For example, a slide rail can be provided on the robot arm 1, and a slider adapted to the slide rail can be provided on the first support member 212. The first support member 212 and the robot arm 1 are movably connected through the slide rail and the slider.

[0056] Reference Figure 3 , Figure 4 and Figure 6In one possible embodiment of this application, one of the first support member 212 and the machine arm 1 has a connecting groove 2121, the extending direction of the connecting groove 2121 being parallel to the extending direction of the machine arm 1. The other of the first support member 212 and the machine arm 1 has a connecting protrusion 11. The first support member 212 and the machine arm 1 are movably connected through the connecting groove 2121 and the connecting protrusion 11. In this way, a reliable movable connection can be formed between the first support member 212 and the machine arm 1, and the structure of the connecting groove 2121 and the connecting protrusion 11 is relatively simple and easy to process.

[0057] It should be noted that, in the first carrier 212 and the arm 1, refer to Figure 3 and Figure 4 The connecting groove 2121 can be disposed on the first support member 212, and the connecting protrusion 11 can be disposed on the machine arm 1; or, the connecting groove 2121 can be disposed on the machine arm 1, and the connecting protrusion 11 can be disposed on the first support member 212. In this respect, the embodiments of this application do not limit the scope of the application.

[0058] Reference Figure 4 and Figure 6 In this embodiment of the application, the scaffolding laying device further includes a guide assembly 4, which is disposed between the first support member 212 and the machine arm 1 to guide the relative movement of the first support member 212 and the machine arm 1. Here, the arrangement of the guide assembly 4 can, on the one hand, reduce the friction between the first support member 212 and the machine arm 1; on the other hand, it can increase the fitting accuracy between the first support member 212 and the machine arm 1, thereby improving the reliability of the scaffolding laying device.

[0059] Reference Figure 4 and Figure 6 In this embodiment, the guide assembly 4 includes a first guide structure 41, which includes a guide wheel set. The guide wheel set is rotatably mounted on one of the first support member 212 and the machine arm 1 for rolling engagement with the other of the first support member 212 and the machine arm 1. Here, the guide wheel set increases the engagement accuracy between the first support member 212 and the machine arm 1 while further reducing the friction between them.

[0060] It should be noted that, in this embodiment, the guide wheel assembly can be rotatably mounted on the first support member 212, thereby rolling with the machine arm 1; or, the guide wheel assembly can also be rotatably mounted on the machine arm 1, thereby rolling with the first support member 212. This embodiment does not limit the scope of the application.

[0061] Reference Figure 4 and Figure 6In this embodiment, the guide assembly 4 includes a second guide structure 42, which includes a rack and a gear. The rack extends parallel to the extension direction of the machine arm 1. The rack is disposed on one of the first support member 212 and the machine arm 1, and the gear is disposed on the other of the first support member 212 and the machine arm 1 for meshing with the rack. Here, the meshing of the rack and gear can further increase the fitting accuracy between the first support member 212 and the machine arm 1, thereby improving the guiding accuracy of the guide assembly 4.

[0062] It should be noted that, in the embodiments of this application, the rack can be disposed on the first support member 212 and the gear can be disposed on the machine arm 1; the rack can be disposed on the machine arm 1 and the gear can be disposed on the first support member 212, and the embodiments of this application do not limit this.

[0063] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment of the application, the first walking component 21 includes a first walking structure 211 and a first support member 212. The first support member 212 is disposed on the first walking structure 211 and is movably connected to the arm 1 along the extension direction of the arm 1. The second walking component 22 includes a second walking structure 221 and a second support member 222. The second walking structure 221 is fixedly connected to the arm 1 through the second support member 222.

[0064] It should be noted that, referring to Figure 3 The adjustment structure 23 can also be set between the second traveling structure 221 and the second bearing member 222 to adjust the relative position between the second traveling structure 221 and the second bearing member 222, thereby further improving the passability of the laying device.

[0065] In this embodiment, after the distance between the first traveling assembly 21 and the second traveling assembly 22 is adjusted, the arm 1 and the first support member 212 can be relatively fixed by friction. Alternatively, in a possible embodiment of this application, the scaffolding device further includes a locking structure, which includes a locking member and a mating member. One of the locking member and the mating member is disposed on the arm 1, and the other is disposed on the first support member 212, for locking the relative position of the arm 1 and the first support member 212. When it is necessary to adjust the distance between the first traveling assembly 21 and the second traveling assembly 22, the locking member and the mating member can be released. After adjustment, the relative position of the arm 1 and the first support member 212 can be locked by the locking structure.

[0066] In this embodiment, the locking member can be disposed on the machine arm 1, and the mating member can be disposed on the first bearing member 212; or, the locking member can be disposed on the first bearing member 212, and the mating member can be disposed on the machine arm 1. This embodiment does not limit the specific choice.

[0067] In this application embodiment, the structural design of the locking member and the mating member can be various. For example, the locking member can be a locking pin and the mating member can be a lock hole; or, the locking member can be a buckle and the mating member can be a slot. This application embodiment does not limit the specific design of the locking member and the mating member.

[0068] Reference Figure 13 , Figure 14 and Figure 15 In this embodiment, the laying device further includes a support member 5, which is connected to the boom 1 for contact with the supporting foundation. Thus, during laying operations, the laying device can contact the supporting foundation via the support member 5, thereby improving the reliability of the laying device.

[0069] In this embodiment, the structural design of the support member 5 can be varied. For example, the support member 5 can be a support rod or a hydraulic cylinder. This embodiment does not limit the specific design of the support member 5.

[0070] Reference Figure 1 In this embodiment of the application, along the extension direction of the boom 1, the boom 1 has a first end for connection with the power equipment 6 and a second end for cantilever operation.

[0071] The frame laying operation process of the frame laying device provided in this application embodiment is as follows: Refer to Figure 8 The power unit 6 drives the scaffolding device to move towards the beam end. Once the distance between the first traveling structure 211 and the beam end is L1 (e.g., 1660mm), the forward movement stops. Then, refer to... Figure 9 and Figure 10 The locking between the first traveling component 21 and the boom 1 is released, and the power unit 6 drives the scaffolding device to continue moving towards the beam end, thereby reducing the distance L2 between the second traveling component 22 and the first traveling component 21. During this process, the position of the first traveling component 21 remains unchanged, and the power unit 6 drives the second traveling component 22 closer to the first traveling component 21 via the boom 1, thereby reducing the distance between the two components. For example, the traveling speed of the power unit 6 can be 1.5 m / min, and the distance L2 between the second traveling component 22 and the first traveling component 21 can be adjusted from 40 m to 18.5 m. Then, refer to... Figure 10 and Figure 11The height L3 of the boom 1 can be adjusted by adjusting structure 23. For example, the height L3 of the boom 1 can be adjusted from 2540mm to 5945mm. Finally, pier or beam erection operations can be carried out. (Refer to...) Figure 12 During pier erection, the hoisting mechanism 3 can directly grab the pier 7 for erection. (Refer to...) Figure 13 and Figure 14 During the bridge girder erection operation, boom 1 can first be supported by support member 5 against the already erected pier 7, and then, referring to... Figure 15 The bridge erection device uses the hoisting mechanism 3 to grab the bridge 8 for erection.
