Description

Technical Field

[0001] The utility model relates to the technical field of bridge reinforcement auxiliary technology, in particular to a jacking, resetting and translation device for an existing bridge. Background Art

[0002] The misalignment of the bridge superstructure seriously affects the operational safety of the bridge, and it needs to be lifted and reset in a timely manner to ensure the safe operation of the bridge. When resetting the bridge superstructure, the selection of a translation device is very necessary to ensure the convenience and safety of the construction.

[0003] Conventional reset and translation devices used in existing bridge superstructures are mostly sliding friction structures, such as Teflon slides. These devices primarily reduce the friction between the bridge superstructure and the reset and translation device, and cooperate with jacks for reset construction, thereby achieving jacking and reset of the bridge superstructure. However, in this structure, the resistance encountered by sliding friction is relatively large, and due to the lack of a one-way limiter, a limit in the direction perpendicular to the intended translation direction is required during implementation. This makes construction control complex, construction accuracy difficult to ensure, and construction convenience is not high. Utility Model Content

[0004] Based on the above description, the utility model provides an existing bridge jacking, resetting and translation device to solve the shortcomings of existing bridge resetting and translation devices that mostly adopt sliding friction structures, which not only have large resistance, but also lack limiting structures, making construction accuracy difficult to guarantee and construction convenience needing to be improved.

[0005] The utility model is realized through the following technical solutions:

[0006] A jacking, resetting and translation device for an existing bridge, comprising:

[0007] The mold base is configured to be rectangular, and a slot is formed by extending downwardly from the center portion of its bottom surface, and the slot extends toward both ends and penetrates the outside of the mold base;

[0008] A slide seat, wherein the main body of the slide seat is configured as a rectangular plate, and a rectangular protrusion is provided at the center of the bottom surface of the slide seat, the protrusion extending downward and just inserted into the groove;

[0009] The position-limiting sliding component is arranged between the slide seat and the mold base, and the two ends of the position-limiting sliding component are respectively fitted with the slide seat and the end surface of the slide seat.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the position-limiting sliding assembly includes a clamping portion provided on two inner side walls of the slot, the cross section of the clamping portion is configured as a trapezoidal structure, and the two clamping portions are arranged opposite to each other and extend toward the center.

[0012] Furthermore, a limiting groove is provided on the outer wall of the protruding portion at the bottom of the slide seat, and the limiting groove is set as a trapezoidal notch. The clamping portion is just inserted into the limiting groove, and a matching groove structure is also provided between the end face of the clamping portion and the bottom surface of the limiting groove.

[0013] Furthermore, a plurality of guide grooves are provided on the top surface of the mold base and the bottom surface of the slot groove, and the bottom surfaces of the plurality of guide grooves are all configured to be arc-shaped and have both ends extending through the outside of the mold base in the longitudinal direction.

[0014] Furthermore, a cover plate is provided inside the guide slot, and the top surface of the guide slot extends toward both sides to form a positioning slot. The cover plate fits inside the positioning slot and completely covers the guide slot, and a bolt hole is provided on the bottom surface of the positioning slot. The cover plate is locked and fixed to the mold base by bolts.

[0015] Furthermore, the top surface of the cover plate is also provided with a through hole, and a plurality of the through holes are provided and arranged at intervals along the extension direction of the guide slide groove, and a steel ball is provided inside each of the through holes.

[0017] Furthermore, a marking scale for recording the length is provided on the inner wall of the slot.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0019] 1. This application is an improvement based on the existing bridge reset and translation device, and adopts a combination of balls and slide rails to replace the existing PTFE slide plate. It can not only convert sliding friction into rolling friction, thereby greatly reducing the resistance encountered during the longitudinal pushing process, but also a number of steel balls can evenly distribute the pressure on the slide seat, avoiding deformation due to local force, and effectively improving the efficiency of the jacking and reset of the bridge superstructure.

The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains.

[0028] Combine Figure 1-4 As shown, an existing bridge lifting, resetting and translation device includes:

[0029] Mold base 1 is the bottom support structure of the entire reset device;

[0030] The slide 2 is movably mounted on the top of the mold base 1 and is used to provide auxiliary support for the bridge superstructure, thereby cooperating with the mold base 1 to perform translation correction;

[0031] The limiting sliding assembly 3 is arranged between the mold base 1 and the slide 2, and is mainly used to reduce the friction between the mold base 1 and the slide 2 so that the staff can use the hydraulic cylinder to push the slide 2 for translation.

[0032] Specifically, in this embodiment, the mold base 1 is set to a rectangular shape, and the center of its top surface is recessed downward to form a slot 11, both ends of the slot 11 extend outward to the outside of the mold base 1;

[0033] The main body of the slide 2 is configured as a rectangular plate, and a rectangular protrusion 21 is formed at the center of the bottom surface thereof extending downward.

[0034] Moreover, the cross section of the mold base 1 is a concave shape, and the cross section of the slide base 2 is an inverted convex shape. The combination of the two allows the protrusion 21 to be precisely engaged with the inside of the slot 11.

[0035] The limiting sliding assembly 3 includes limiting grooves 31 provided on the two outer walls of the protrusion 21. The limiting grooves 31 are set as trapezoidal notches, and the two inner walls of the slot 11 are correspondingly provided with matching trapezoidal clamping parts 12. The clamping parts 12 can be just buckled into the inside of the notch, so that the slide 2 will not overturn to the sides when it moves horizontally on the top of the mold base 1, and the end face of the clamping part 12 and the bottom surface of the limiting groove 31 should also be provided with a matching groove structure. The staff only needs to assemble the two by pushing from the side, and the slide 2 assembled on the mold base 1 can only move along the extension direction of its slot 11.

[0036] A plurality of guide grooves 32 are provided on the top surface of the mold base 1 and the bottom surface of the slot 11. The top surface of each guide groove 32 has a positioning groove 33 extending to both sides. A step surface is formed between the positioning groove 33 and the guide groove 32, and a bolt hole is provided on the step surface. At the same time, a cover plate 34 is fitted in the positioning groove 33. The top surface of the cover plate 34 is penetrated by a hole and is locked in the positioning groove 33 by bolts, so that its top surface is arranged flush with the surface of the mold base 1.

[0037] A number of circular through holes are provided on the surface of the cover plate 34, which are arranged at intervals along the surface of the cover plate 34, and a steel ball 35 is provided inside each through hole. At the same time, a conveying groove 36 is provided on the bottom surface of the slide 2 and the bottom surface of the protrusion 21. Each conveying groove 36 is arranged directly above a guide slide groove 32, and the bottom surfaces of the conveying groove 36 and the guide slide groove 32 are both set to be arc-shaped and respectively abut against the two ends of the steel ball 35. Therefore, when the top slide 2 moves, the steel ball 35 will rotate inside the cover plate 34, thereby utilizing rolling friction to achieve longitudinal adjustment of the slide 2.

[0038] During the adjustment process, in order to facilitate the observation of the longitudinal pushing distance, an identification scale for recording the length can be provided on the inner wall of the slot 11, so that the staff can more intuitively understand the specific length of the movement, thereby further improving the construction accuracy.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
