[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The embodiment of the present application provides a T-beam maintenance system, which can solve the technical problem that in the related technology, bridge inspection vehicles, full-bridge brackets, hangers and other maintenance devices are used to inspect T-beams, but some sites, such as operating railway lines, are not convenient for using bridge inspection vehicles and building full-bridge brackets, and the use of hangers may cause certain damage to the beam body.

[0030] See also Figure 1 As shown, a T-beam maintenance system provided in an embodiment of the present application comprises: at least one group of T-beams, each group of the T-beams comprising two T-beams 1, and the two T-beams 1 are spaced apart along the transverse bridge direction; a support structure, the support structure is erected between the two T-beams 1 of each group, the support structure can be a structure with a longer length along the longitudinal bridge direction, or it can be a structure with multiple shorter lengths along the longitudinal bridge direction, and multiple support structures can be spaced apart along the longitudinal bridge direction between the two T-beams 1; a moving track, the moving track extends along the longitudinal bridge direction, and the moving track is installed at the bottom of the supporting structure. In this embodiment, the moving track is fixed to the bottom of multiple supporting structures; a moving rod 4, the moving rod 4 is installed on the moving track, and the moving rod 4 can move along the moving track, the moving rod 4 is connected to a working platform 7, that is, the working platform 7 is fixed to the moving rod 4, and the moving rod 4 moves in the moving track to drive the working platform 7 to move together, so as to inspect the T-beam 1 or perform other operations.

[0031] The embodiment of the present application sets a supporting structure between the two T-beams 1 in each group, and uses the supporting structure to install a movable track at the bottom thereof. The movable track can be installed at the bottom of the supporting structure by directly welding the movable track to the supporting structure, or by adding other structures to indirectly install the movable track to the supporting structure, and the maintenance platform is moved on the movable track through the moving rod 4, so as to realize other operations such as maintenance of various positions of the T-beam 1. This solves the technical problem that when maintenance devices such as bridge inspection vehicles, full-span brackets, and hangers are used to inspect T-beams in the related technology, some sites, such as railway operating lines, are not convenient for using bridge inspection vehicles and building full-span brackets, and the use of hangers may cause certain damage to the beam body. When the hangers in the related technology are used for construction, it is necessary to nail part of the fixing device into the side of the T-beam 1, which will cause certain damage to the beam body of the T-beam 1. In this embodiment, the structure between the two T-beams 1 is used to directly place part of the supporting structure between the two T-beams 1 structures, and the T-beam 1 does not need to be excavated or nailed. Moreover, the overall weight of the T-beam maintenance system is relatively light, and the impact on the mass structure of the T-beam 1 is minimal. The installation is quick and simple, and requires less manpower, which greatly reduces the maintenance construction cost of the T-beam 1. The construction process is economical and fast and does not affect the original road traffic.

[0032] See also Figure 2As shown, in some other embodiments, the T beam 1 includes a corbel 11, and the support structure includes: a support beam 21, the support beam 21 is installed at the top of the two corbels 11 of the T beam 1, in this embodiment, the support beam 21 is set as a shoulder beam, and the shoulder beam is prefabricated in a factory according to the distance between the two corbels 11 and the shape of the top of the corbel 11, so that when the shoulder beam is placed at the top of the corbel 11, the bottom surface of the shoulder beam and the contact point of the corbel 11 can be closely fitted; a cross beam 22, the cross beam 22 is connected to the support by a connection system 23 The beam 21 is fixed, and the cross beam 22 is in contact with the bottom surfaces of the two T beams 1. The movable track is installed on the cross beam 22. After the shoulder pole beam is installed on the top surface of the corbel 11, since the corbel 11 has a certain thickness along the vertical direction, the cross beam 22 is placed at the bottom end of the T beam 1 and in contact with the T beam 1. The shoulder pole beam and the cross beam 22 can be connected through a connecting system 23. In this embodiment, the connecting system 23 includes a plurality of hoops. The hoops can be directly tightened with bolts to complete the installation and fixation between the shoulder pole beam and the cross beam 22, which is relatively convenient and quick.

[0033] In some optional embodiments, at least two suspensions are installed on the side of the beam 22 away from the T-beam 1. In this embodiment, the length of the beam 22 along the transverse direction is set to span the two T-beams 1, and is in contact with the sides of the two T-beams 1 away from each other. At least two of the suspensions are symmetrically arranged at both ends of the beam 22. The suspension is arranged on the side of the beam 22 away from the T-beam 1, and the movable track is installed on the suspension. That is, in this embodiment, the movable track is indirectly connected to the beam 22. The suspension and the beam 22 can be integrally formed during factory manufacturing, or they can be installed and fixed on site.

[0034] In some optional embodiments, the suspension includes: a vertical plate 241, one end of the vertical plate 241 is fixed to the cross beam 22, and the other end extends toward a side away from the T-beam 1, the vertical plate 241 is arranged in the vertical direction, and the extension direction of the vertical plate 241 is perpendicular to the cross beam 22; a cross plate 242, the cross plate 242 is fixed to one end of the vertical plate 241 away from the cross beam 22, preferably, the cross plate 242 and the vertical plate 241 are perpendicular to each other, and the vertical plate 241 and the cross plate 242 form an "L" shape, the movable track is installed on the cross plate 242, and the two cross plates 242 are respectively arranged at both ends of the cross beam 22, and when the movable rod 4 moves in the movable track, it has a small distance with the vertical plate 241, so that the vertical plate 241 does not interfere with the movement of the movable rod 4. Preferably, an anti-skid structure is installed on the side of the support beam 21 in contact with the corbel 11. Since the shoulder pole beam can be prefabricated in the factory according to the distance between the two corbels 11 and the shape of the top end of the corbel 11, when the shoulder pole beam is placed on the top end of the corbel 11, the bottom surface of the shoulder pole beam and the contact point of the corbel 11 can fit tightly. Then, during installation, the shoulder pole beam can be directly erected between the two corbels 11. However, there may be some errors between the corbel 11 and the shoulder pole beam during manufacturing. Therefore, an anti-skid structure is installed on the side of the support beam 21 in contact with the corbel 11, that is, an anti-skid structure is installed on the side of the shoulder pole beam in contact with the corbel 11. The anti-skid structure may have some elasticity, and the elastic anti-skid structure may be fault-tolerant, so that even if there are some errors between the corbel 11 and the shoulder pole beam during manufacturing, it will not affect the installation of the shoulder pole beam, and the anti-skid structure can further prevent damage to the beam body of the T-beam 1 when the shoulder pole beam is placed on the corbel 11.

[0035] In some optional embodiments, the movable track includes multiple I-beams 3, each of the I-beams 3 extends along the longitudinal bridge direction, and each of the I-beams 3 is installed on multiple suspensions. In this embodiment, the I-beams 3 are installed on the cross bars, and the installation method can be welding; the movable rod 4 is mounted on multiple I-beams 3, and the movable rod 4 is provided with a limit assembly, which cooperates with the I-beams 3 to prevent the movable rod 4 from detaching from the I-beams 3, thereby enhancing the safety of the T-beam maintenance system.

[0036] Preferably, the limiting assembly includes multiple groups of limiting members, each group of limiting members cooperates with each of the I-beams 3, the limiting members include two limiting plates 5, the limiting plates 5 are arranged around the outer periphery of the moving rod 4, and each group of two limiting plates 5 are symmetrically arranged on both sides of the I-beam 3 along the transverse bridge direction. In this embodiment, the cross-section of the moving rod 4 is set to be circular, and the moving rod 4 can move on the I-beam 3 by utilizing its own performance. The limiting members are set to two limiting plates 5 symmetrically arranged on both sides of the I-beam 3, so that the moving rod 4 will not separate from the I-beam 3 during the movement, and the structure is simple and can save materials.

[0037] In some optional embodiments, the mobile rod 4 is also fixed with a rotating disk, the rotating disk is coaxially arranged with the mobile rod 4, the rotating disk is fixed at the middle part of the mobile rod 4, and the rotating disk and the limit assembly are arranged at intervals. It should be understood that in this embodiment, the mobile rod 4 moves along the longitudinal bridge direction on the I-beam 3 by rotating the rotating disk, so that the mobile rod 4 rotates synchronously to achieve movement. Preferably, the T-beam maintenance system also includes a suspension rod 6: one end of the suspension rod 6 is fixed to the working platform 7, and the other end is connected to the mobile rod 4. The suspension rod 6 is connected to the end of the mobile rod 4 and is fixed with a collar. The mobile rod 4 is penetrated by the collar, so that the mobile rod 4 is rotatably connected with the suspension rod 6. During the construction operation, the staff stands on the working platform 7. When the maintenance of the T-beam 1 at one position is completed, the staff manually rotates the rotating disk to drive the mobile rod 4 to rotate. Since the suspension rod 6 is connected to the mobile rod 4 through the collar, when the mobile rod 4 rotates, the suspension rod 6 can remain motionless, thereby realizing the maintenance of different positions of the T-beam 1.
