[0028] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 8 As shown, the utility model proposes a bridge maintenance and repair device, which mainly includes a track 2, a base 6 and a concave-shaped lifting seat 10 with a closed bottom, wherein:

[0031] The track 2 is provided in several pieces and is installed on the bridge guardrail 1 in sections. Both sides of the track 2 are rotatably connected with a clamping plate 3. The clamping plate 3 and the track 2 are connected by bolts 4. By adjusting the tightness of the bolts 4, the mutual rotation damping between the clamping plate 3 and the track 2 can be adjusted. When in use, it can be adjusted according to the needs of different bridge guardrails 1. The top and rear parts of the track 2 are provided with a horizontally arranged slide rail 5; the base 6 is provided thereon, and the track 2 and the base 6 are connected by a mobile structure 7. When powered on, the base 6 and the above-mentioned components can slide in the slide rail 5 opened on the track 2 under the drive of the mobile structure 7.

[0032] Next, a rotating platform 27 is fixedly connected to the rear of the top of the base 6, and a rotating arm 8 facing forward is rotatably connected to the top of the rotating platform 27, and the lifting seat 10 is rotatably connected to the front end of the rotating arm 8, and the rotating platform 27 and the rotating arm 8, as well as the rotating arm 8 and the lifting seat 10 are all connected to each other through the telescopic cylinder 24. Therefore, the mutual angle between the rotating platform 27 and the rotating arm 8, as well as the rotating arm 8 and the lifting seat 10 can be adjusted by driving the telescopic cylinder 24, and the rear end of the base 6 is fixedly connected to a counterweight box 9; maintenance tools can be placed in it, and objects with a certain mass can also be placed in it to balance the center of the entire device, so as to ensure that the center of gravity of the device always falls near the bridge guardrail 1.

[0033] The front end of the lifting seat 10 is located in the concave shape, and both sides of the inner surface are provided with a slide groove 11. A lifting platform 12 is slidably connected in the slide groove 11. The front end of the lifting platform 12 is fixedly connected to a load-bearing part 13. When in use, the maintenance personnel stand inside the load-bearing part 13. By sliding the lifting platform 12 in the slide groove 11, its height can be adjusted to perform maintenance and repair on bridges of different heights. In order to make the lifting platform 12 and the load-bearing part 13 rise and fall smoothly, the utility model is also fixedly connected to a motor table 16 at the rear of the top of the lifting seat 10. Both sides of the top of the motor table 16 are fixedly connected to a motor 17. A winding roller 18 is fixedly connected between the motors 17 on both sides. Both sides of the middle of the winding roller 18 are wound with a sling rope 19, and the bottom end of the sling rope 19 is fixedly connected to the lifting platform 12. By the forward and reverse rotation of the motor 17, the winding roller 18 can be driven to release or reel in the sling rope 19, thereby completing the operation of raising or lowering.

[0034] During this process, the lifting rope 19 will repeatedly rub against the concave edge of the lifting seat 10, which will cause wear on the lifting rope 19 over time, causing safety hazards. Therefore, in order to alleviate the above problem, the utility model has grooves 25 for matching with the lifting rope 19 on both sides of the middle of the top of the lifting seat 10, and the bottom of the groove 25 is rotatably connected to a roller 26. Therefore, during the process of releasing or winding the lifting rope 19, the friction can be reduced by driving the roller 26 to roll, thereby ensuring its service life.

[0035] The lifting platform 12 and the supporting part 13 are fixed at the designated location after they have reached the designated location. At this time, if they are only supported by the motor 17, their service life will be affected. In order to solve the above problems, the utility model is provided with a plurality of evenly distributed vertical through holes 14 on the slide slot 11, in which a latch 15 is inserted, and the latch 15 passes through the through hole 14 and is inserted into a recess provided on the lifting platform 12. At the same time, a tool placement box 28 is provided inside the supporting part 13. Therefore, when lifting is required, the user can remove the restrictions of the lifting platform 12 and the lifting seat 10 by pulling out the latch 15. When the lifting platform 12 is lifted to the designated position, the latch 15 is inserted into the through hole 14 at the target position and deeply buckled into the recess in the lifting platform 12 to complete the limiting. At this time, the lifting platform 12 relies on the dual support of the latch 15 and the motor 17, reducing the support burden of any one of the components.

[0036] In order to further explain the specific working principle of the utility model, the above-mentioned moving structure 7 includes a wheel seat 20 fixedly connected to both sides of the bottom end of the base 6 and the front and rear ends, and a moving wheel 21 rolling on the slide groove 11 is arranged in the wheel seat 20, and the separated surfaces of the front and rear end moving wheels 21 are fixedly connected to a motor 22, and the top end of the motor 22 is fixedly connected to a motor seat 23, and the motor seat 23 is fixedly connected to the bottom end of the base 6.

[0037] Therefore, the device as a whole can be moved on the slide 11 by driving the motor 22 .

[0038] It should be noted that the electrical components in this article are all connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of the market equipment.

[0039] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
