[0027] The utility model will be explained below through several specific embodiments. In order to keep the following explanation of the utility model embodiment clear and concise, the detailed explanation of known functions and known components can be omitted. When any component of the utility model embodiment appears in more than one figure, the component can be indicated by the same reference numeral in each figure Figure 1 A front view of a railway high bridge maintenance and repair device provided by the utility model embodiment, Figure 2 A left view of a railway high bridge maintenance and repair device provided by the utility model embodiment, Figure 3 A Figure 2 A local structure amplification schematic view of the middle A area, Figure 4 A right view of a railway high bridge maintenance and repair device provided by the utility model embodiment, Figure 5 A top view of a railway high bridge maintenance and repair device provided by the utility model embodiment. As shown in Figures 1 to 5 A railway high bridge maintenance and repair device, comprising: a support 1, a working platform 2 connected at the bottom of the support 1 and a slidable clamping structure 3 connected at the top of the support 1, the working platform 2 and the slidable clamping structure 3 are arranged on the same side, wherein the slidable clamping structure 3 comprises: a fixed frame 30, a roller assembly 31 and a locking piece 32, the fixed frame 30 is connected to the top of the support 1, the roller assembly 31 is connected to the fixed frame 30, the roller assembly 31 is used to adapt to the high bridge, so that the railway high bridge maintenance and repair device slides on the bridge railing, the locking piece 32 is connected to the fixed frame 30, and is used to lock the position of the railway high bridge maintenance and repair device on the high bridge railing.

[0028] By setting the working platform at the bottom of the support 1 and the slidable clamping structure 3 at the top of the support, the slidable clamping structure 3 comprises the fixed frame 30, the roller assembly 31 and the locking piece 32, the roller assembly 31 is placed on the bridge railing during high bridge maintenance, and the device is locked and fixed by the locking piece 32, the worker maintains and repairs the bridge on the working platform 2, when the position is repaired, the locking piece 32 is opened, so that the roller assembly 31 can move on the railing, the whole device is moved to the next maintenance point, and the locking piece 32 is locked again for maintenance at the next maintenance point. The device is convenient to move, safe and high in working efficiency during bridge maintenance through the roller assembly 31 and the locking piece 32.

[0029] Refer again Figure 1 The roller assembly 31 includes a pair of fixed rods 310 symmetrically arranged at the bottom of the fixed frame 30 and a roller 311 connected between the two fixed rods 310. The length of the fixed rods 310 is greater than the length from the roller 311 to the fixed frame 30, so that when the roller 311 is rollingly connected to the bridge railing, the bridge railing can be stuck between the two fixed rods 310. If the length of the fixed rods 310 is less than or equal to the length from the roller 311 to the fixed frame 30, the roller 311 may slide off the bridge railing during movement, making the movement of the railway high-level bridge maintenance and repair device unstable. If the length of the fixed rods 310 is greater than the length from the roller 311 to the fixed frame 30, the bridge railing will be stuck between the two fixed rods 310, making the movement of the device more stable.

[0030] The support 1 is a ladder to facilitate workers to enter the work platform 2. The support 1 is a ladder, so that workers can climb the ladder to the work platform 2 to repair the bridge. It makes it easy for workers to enter and exit the work platform 2 when they need to repair the bridge. Without the help of other tools, one person can complete the movement and can repair multiple repair points on the bridge.

[0031] Refer again Figures 1 to 5 The locking member 32 includes two connectors 320 and a pull rope 321. The two connectors 320 are connected to the end of the fixed frame 30 away from the bracket 1. The pull rope 321 passes through the two connectors 320 so that the fixed frame 30 is fixed when the pull rope 321 is tied to the bridge railing. It should be understood that the connector 320 described in this embodiment can be a bent steel bar welded to the fixed frame 30, or it can be a steel plate with a hole opened to allow the pull rope 321 to pass through. The connection between the connector 320 and the fixed frame 30 is welded, making the connection more stable. Using the pull rope 321 for fixing makes it easy to disassemble and the fixation is more firm, which improves the safety of the device.

[0032] When in use, at the location that needs maintenance, the roller assembly 31 is brought into contact with the railing, and then the pull rope 321 passing through the two connecting pieces 320 is tightened and then tied to the railing below to fix the fixing frame 30, thereby fixing the entire device and preventing it from sliding or flipping outward, thereby improving the stability of the entire device. The staff maintains and repairs the bridge on the working platform 2. When the maintenance at that location is completed, the pull rope 321 is opened so that the roller assembly 31 can be moved on the railing, and the entire device is moved to the next maintenance point. The pull rope 321 is straightened and tied to the railing again, and maintenance is carried out on the next maintenance point. The device is easy to move when performing bridge maintenance through the roller assembly 31 and the pull rope 321, has high safety, and can improve work efficiency.

[0033] Referring to FIG. 1 again, the stabilizing component 4 includes a connecting rod 40 and a clamping groove 41. The connecting rod 40 is connected to the support 1 vertically, and the connecting rod 40 is located at the area of the support 1 close to the fixed frame 30. The clamping groove 41 is connected to the end of the connecting rod 40 away from the support 1. The connecting rod 40 is welded to the support 1. Since the railing usually has multiple horizontal rods, the clamping groove 41 should be clamped at a suitable position of the horizontal rod of the railing during use, so as to further ensure that the construction device will not move during construction, the connecting rod 40 bears the tension, shares the stress of the support 1, and plays a horizontal and vertical constraint role together with the clamping groove 41, thereby improving the stability of the device during operation, and ensuring the safety of the workers.

[0034] Referring to FIG. 1 again, Figure 1 and Figure 2 , the stabilizing component 4 further includes a first support rod 42. One end of the first support rod 42 is connected to the support 1, and the other end of the first support rod 42 is obliquely connected to the fixed frame 30, so that the fixed frame 30, the support 1 and the first support rod 42 form a triangular structure. In order to make it more stable, the first support rod 42 can have two, and one end of each of the two first support rods 42 is connected to the ladder beam of the ladder stand, and the other end of each of the two first support rods 42 is obliquely connected to the side of the connecting frame. The first support rod 42 is connected to the ladder beam of the ladder stand and the side of the connecting frame, so that it will not affect the movement of the workers working on the ladder stand. The formation of the triangular structure makes the device more stable while moving conveniently, thereby ensuring the safety of the workers during operation.

[0035] Referring to FIG. 1 again, Figure 1 and Figure 2 , the stabilizing component 4 further includes a second support rod 43. One end of the second support rod 43 is connected to the support 1, and the other end of the second support rod 43 is obliquely connected to the fixed frame 30, so that the support 1, the fixed frame 30 and the second support rod 43 form a triangular structure. The formation of the triangular structure makes the device more stable while moving conveniently, thereby ensuring the safety of the workers during operation.

[0036] The connecting rod 40 is an L-shaped steel, and the connecting rod 40 is connected to the support 1 by bolts. The connection and disconnection of the connecting rod 40 are more simple and stable through the bolt connection.

[0037] The fixed frame 30 and the support 1, the support 1 and the standing plate 20, and the standing plate 20 and the protective fence 21 are fixed by welding. The two are firmly fixed together, thereby further improving the stability.

[0038] The height of the protective fence 21 is 90 cm. This height avoids affecting the maintenance due to the too high height of the protective fence, and can also provide good protection for the workers.

[0039] The included angle between the first support rod 42 and the ladder beam of the support 1 is 21°, the second support rod 43 is connected at 2 / 3 of the width of the guardrail, and the included angle between the second support rod 43 and the guardrail is 21°. Through stress analysis, the stress of such an included angle is reasonable and more stable.

[0040] The manufacturing method of the device is as follows:

[0041] 1) Component pre-processing:

[0042] According to the design drawing requirements, various steel components such as stainless steel square tubes are processed, including cutting and processing components into specific shapes and pre-punching holes at specific positions.

[0043] 2) Welding:

[0044] According to the design drawing, the main components are welded, and the welding process is required to be high, without defects such as slag inclusion, cracks, pores, and undercut, to ensure the strength of the connection. In the parts that need to bear more force, the weld length is as long as possible, and structural checking is carried out.

[0045] 3) Drilling:

[0046] Select L-shaped steel as the connecting rod 40, drill holes, and drill holes at appropriate positions of the support 1, so that the connecting rod 40 and the support 1 can be connected by bolts. Considering the installation of the steel pipe component later, the drilling should be strictly according to the design distance, with a maximum allowable deviation of ±2mm, and the hole inclination should not exceed 2° per 10mm. After the hole is formed, use a blower to clean the residue in the hole.

[0047] 4) Assembly:

[0048] Use nuts to fix the connecting rod 40 on the support 1, which is to prevent the construction frame from deforming too much when in use.

[0049] 5) Use and installation:

[0050] In use,

[0051] Place the construction frame so that the guardrail is clamped between the first fixed rod and the second fixed rod, which plays a vertical support and vertical plane moment constraint. The roller can move to the appropriate position along the guardrail, the fixed clamping groove 41 is on the bottom crossbar of the guardrail, the safety belt is fixed around the guardrail for one turn, and is tied to the construction personnel, which plays a protective role. Before construction, the installed construction frame should be checked to check whether it is firmly installed.

[0052] The above disclosure is only a few specific embodiments of the present application, but the embodiments of the present application are not limited to this. Any changes that can be thought of by those skilled in the art should fall within the protection scope of the present application.
