[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Such as Figures 1-3As shown in the figure, a repair device for railway bridge tunnels includes a support inner frame 1. The support inner frame 1 is an arc-shaped structure. At both ends of the support inner frame 1, a pair of support bases 2 are connected. A pair of height adjustment structures 3 are arranged on the pair of support bases 2 and connected to both ends of the support inner frame 1. On the front and back sides of the support inner frame 1, a pair of arc-shaped plates 5 are provided, and a pair of arc-shaped chutes are symmetrically opened on the pair of arc-shaped plates 5.
[0019] This repair device for railway bridge tunnels adopts a frame structure design. The support inner frame 1 with an arc-shaped structure and a pair of support bases 2 form a complete frame structure. This frame structure uses the pair of support bases 2 as supports. During maintenance, the pair of support bases 2 straddle both sides of the railway track and are arranged in parallel to support the upper support inner frame 1. Moreover, a pair of height adjustment structures 3 are arranged on the pair of support bases 2 and connected to both ends of the support inner frame 1, which plays a role in supporting and height adjustment of the support inner frame 1. And the height adjustment structure 3 can adjust the height of the support inner frame 1 to ensure the passing of railway vehicles, and also enable the construction workers to be closer to the top of the tunnel for easy maintenance.
[0020] A pair of sliding blocks 6 are symmetrically assembled on the pair of arc-shaped chutes. A bearing frame 7 is connected between the pair of sliding blocks 6. Climbing frames 8 are arranged in a grid pattern on the bearing frame 7. On one side of the bearing frame 7, a repair mortar inlet 9 is provided. A mortar inlet pipe 10 is connected to the repair mortar inlet 9. A mortar lifting pump 11 is connected to the mortar inlet pipe 10. The mortar inlet pipe 10 extends from one side of the support base 2. A pair of climbing frames 12 extend from the outer sides of the support inner frame 1.
[0021] A sliding system is formed by a pair of arc-shaped chutes on the pair of arc-shaped plates 5 and a pair of sliding blocks 6. Furthermore, a position adjustment component 4 is provided on one side of each arc-shaped chute, and the position adjustment component 4 is linked with the corresponding sliding block 6. The sliding block 6 can be adjusted to slide in the arc-shaped chute through the position adjustment component 4. The arc-shaped chute plays a role in limiting and guiding the sliding block 6. And the movement of the pair of sliding blocks 6 will drive the middle bearing frame 7 to move. The bearing frame 7 is the working platform for the repair work. The climbing frames 8 provide footholds for the repair personnel and a tying point for the safety ropes of the repair personnel. When the repair personnel are repairing, mortar is an essential material, which can be used for injecting seams and surface coating. The mortar is transported to the repair mortar inlet 9 with the mortar lifting pump 11 as the power and the mortar inlet pipe 10 as the passage. The mortar inlet pipe 10 extends from one side of the support base 2, and the mortar inlet pipe 10 is a hose structure with telescopic redundancy, so that the movement margin of the mortar inlet pipe 10 can be provided when adjusting the movement of the bearing frame 7 according to different repair positions. The climbing frames 12 facilitate the maintenance personnel to climb onto the bearing frame 7.
[0022] Furthermore, at least two sets of moving devices 13 are respectively arranged on a pair of support bases 2. The moving devices 13 are multiple roller structures arranged symmetrically. In this way, the support inner frame 1 can be moved by the moving devices 13 to move forward in the tunnel and reach the repair position.
[0023] Furthermore, a number of fixed anchor points are arranged on a pair of support inner frames 1, and corresponding grooves are arranged on the side wall of the tunnel. The overall fixation of the frame structure is realized through the connection between the fixed anchor points and the grooves.
[0024] Furthermore, the above-mentioned height adjustment structure 3 includes a number of telescopic columns 301. A number of telescopic grooves are formed on the support base 2. A number of telescopic columns 301 are inserted into the number of telescopic grooves. The ends of the number of telescopic columns 301 are connected to the ends of the support inner frame 1. An adjustment cylinder 302 is arranged on the support base 2. The telescopic end of the adjustment cylinder 302 is connected to the end of the support inner frame 1;
[0025] In the specific implementation process, taking the adjustment cylinder 302 as the power, the support inner frame 1 is lifted by the adjustment cylinder 302 to adjust the height of the support inner frame 1. With the limitation of the telescopic groove and the telescopic column 301, the lifting stability effect of the support inner frame 1 is achieved.
[0026] Furthermore, the position adjustment component 4 includes an adjustment motor. The adjustment motor is assembled on the sliding block 6. A gear 401 is arranged on the driving end of the adjustment motor. An arc-shaped rack 402 is arranged on one side of the arc-shaped chute. The arc-shaped rack 402 meshes with the gear 401. In the specific implementation process, the driving gear 401 can be adjusted to rotate through the adjustment motor. Then, by using the meshing of the gear 401 and the arc-shaped rack 402, and the reverse pushing effect of the arc-shaped rack 402, the sliding block 6 is made to slide, thereby adjusting the position of the bearing frame 7.
[0027] In summary, generally speaking, this railway bridge tunnel repair device uses a pair of movable support bases 2 arranged in parallel and a support inner frame 1 to form a frame system. The height of this frame system is adjustable and can accommodate trains passing through. And a bearing frame 7 with adjustable position is arranged on the support inner frame 1.
