Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a track installation device for a steel structure bridge inspection vehicle and a bridge. Background Technology

[0002] The existing installation process for bridge inspection vehicle tracks on steel structure bridges is as follows: Generally, the inspection vehicle tracks are welded to the steel structure beams before the beams are installed; then, the inspection vehicle tracks are installed together with the steel structure beams. While welding the two sections of steel structure beams end to end, the inspection vehicle tracks on adjacent steel structure beams are also welded together.

[0003] However, the installation process of the aforementioned bridge inspection vehicle track has the following defects: 1. Misalignment is inevitable during the installation of steel structure beams, which directly affects the linearity of the track installation; in addition, the track may be damaged during the beam installation process.

[0004] 2. Large-span steel structure beams are generally divided into many segments, with each segment being relatively short and having a large number of track butt welds. Utility Model Content

[0009] According to the above technical solution, the length of the rotating shaft is 10cm to 15cm longer than the length of the roller; the length of the rubber block is 1cm to 2cm.

[0010] According to the above technical solution, the roller has an annular groove around its circumference. The cross-section of the annular groove is divided into a bottom surface and two side surfaces. The width of the bottom surface is the same as the width of the standard section of the track.

[0025] Reference Figures 1-3 As shown, this utility model provides a track installation device for a steel structure bridge inspection vehicle.

[0026] Example 1 The bridge inspection vehicle track is composed of several standard track sections connected end to end; including Support frame 2, several sets of support frames are arranged at intervals along the length of bridge beam 3; Roller structure 4: Roller structures are fixedly installed on each set of support frames. All roller structures are located on the same straight line and together form a slide. Clamp 5, the clamp is fixedly connected to the end of the first standard section of track; The wire rope traction mechanism 6 has a construction platform 7 at one end of the bridge for welding two adjacent standard track sections; and an installation platform 8 at the other end of the bridge for installing the wire rope traction mechanism. The wire rope traction mechanism is connected to the clamp and pulls the welded standard track sections to move on the slide.

[0027] In this invention, each bridge beam segment is equipped with a roller structure mounted on a support frame. Several roller structures form a slide rail located at the bottom of the bridge beam, which is used for positioning and transporting standard track sections. The standard track sections are finished by welding on a construction platform and then placed on the slide rail. A wire rope traction mechanism located at the other end of the bridge pulls the welded standard track section along the slide rail, thereby transporting the entire welded bridge inspection vehicle track from the construction platform to directly beneath the bridge beam. Once the welded bridge inspection vehicle track is transported to the designed position directly beneath the bridge beam, it is welded integrally onto the beam, thus completing the precise installation of the bridge inspection vehicle track on the track beam.

[0028] Based on the above structure, firstly, it solves the problem of inconvenient transportation of track components when installing the bridge inspection vehicle track for cross-river and cross-line steel structure bridges; secondly, the standard track sections do not need to be hoisted along with individual bridge beam sections, removing the limitation on the size of the standard track sections, increasing the length of the standard track sections, reducing the number of track butt welds, and improving installation efficiency and quality; thirdly, it improves the linearity of the bridge inspection vehicle track installation, enhances the installation quality of the bridge inspection vehicle track, and avoids the problem of slippage and jamming of the bridge inspection vehicle.

[0029] Example 2 Based on Example 1, two preferred roller structures are presented.

[0030] The first type of roller structure includes a rotating shaft fixed to a support frame and a roller rotatably connected to the rotating shaft; the roller can only be rotatably connected to the rotating shaft, such as by a bearing. The advantage of this roller structure is its simplicity.

[0031] The second method, in order to improve the installation accuracy of the bridge inspection vehicle track and reduce the installation difficulty of the support frame on the bridge beam, includes a rotating shaft 4-1 fixed on the support frame, a roller 4-2 rotatably connected to the rotating shaft, and rubber blocks 4-3 for limiting the position; the roller is sleeved on the rotating shaft and slides on the rotating shaft; the rubber blocks are sleeved on the rotating shaft and located on both sides of the roller; under certain action, the rubber blocks slide to adjust the position of the roller on the rotating shaft.

[0032] Due to welding errors between bridge beams and between standard track sections, these errors can cause the support frame to deviate from its designed position, resulting in the roller structure falling off the straight line where the slide is designed to be. Damped rubber blocks restrict the rollers' position on the rotating shaft; operators then drive the rubber blocks to slide axially on the shaft, adjusting the rollers' positions to ensure all rollers are on the straight line where the slide is designed to be.

[0033] In the above embodiments, preferably, the length of the rotating shaft is 10cm to 15cm longer than the length of the roller; and the length of the rubber block is 1cm to 2cm.

[0034] Example 3 Based on Example 2, in order to prevent the track standard section from shifting during the movement of the roller structure, the roller is provided with an annular groove 4-4 around its perimeter. The cross-section of the annular groove is divided into a bottom surface and two side surfaces, and the width of the bottom surface is the same as the width of the track standard section.

[0035] In embodiments 2 and 3, each set of support frames includes two support frames, which are respectively connected to the two ends of the rotating shaft.

[0036] In embodiments 1-3, the preferred interval of the support frame along the direction of the bridge beam is 2m to 4m.

[0037] Example 4 Based on embodiments 1-3, the wire rope traction mechanism includes a first wire rope 6-1 and a traction drum structure 6-2, with the two ends of the first wire rope connected between the clamp and the traction drum structure, respectively.

[0038] After the clamp holds the standard section of the track in the first section, the first steel wire rope is pulled by the traction drum structure, driving the standard section of the track to slide on the slide.

[0039] To facilitate the connection of the first wire rope and clamp to the first standard section of the track, a fixed pulley 6-3 and a reciprocating wire rope 6-4 are also included. Several fixed pulleys are provided and are fixed to the bridge beam, construction platform, or installation platform respectively. The reciprocating wire rope is connected to the fixed pulley and the traction drum structure to form a ring structure, and the traction drum structure pulls the reciprocating wire rope to rotate. The clamp is connected to a reciprocating wire rope, which carries the clamp and the first wire rope connected to the clamp from the installation platform to the construction platform.

[0040] In this implementation, when pulling the first standard track section, the clamp and the first wire rope located at the installation platform are connected to a node of the reciprocating wire rope via a reciprocating wire rope. Subsequently, the rotation of the traction drum structure drives the reciprocating wire rope to carry the clamp and the first wire rope from the installation platform to the construction platform.

[0041] In embodiments 1-4, a hanging basket 9 is also included, which is connected to the bridge.

[0042] This utility model also provides a bridge, on which a steel structure bridge inspection vehicle track installation device as described in any of the above is provided.

[0043] Construction steps of this utility model: S1: Before installing the bridge beam, determine the installation position of the bridge inspection vehicle track in advance, and install the support frame on the bridge beam accordingly. The installation position of the support frame on the bridge beam along the transverse direction of the bridge can be determined according to the adjustment requirements of the bridge inspection vehicle track on the bridge connector along the transverse direction of the bridge. The spacing of the support frames along the length of the bridge can be determined according to the length of the standard track section, generally with a spacing of 3m.

[0044] S2: After the bridge beam is installed, a winch is installed on the installation platform at one end of the bridge beam as a wire rope traction mechanism, forming a reciprocating traction system together with the reciprocating wire rope and several fixed pulleys. Under the action of the reciprocating traction system, the clamp and the first wire rope pass through the installation position of the bridge inspection vehicle track. The first standard section of the track is connected to the reciprocating traction system through the clamp, and then the reciprocating traction system pulls the bridge inspection vehicle track to the installation position.

[0045] S3: Accurately measure the installation position of the bridge inspection vehicle track as designed, and adjust the actual position of the slide rail using the rubber blocks on the rotating shaft to ensure that the designed installation position of the bridge inspection vehicle track coincides with the actual position of the slide rail. Specifically, the gap between the support frames should be greater than the length of the rollers, generally 10-15cm wide is appropriate. Adjustment method for the transverse bridge track beam position: The rotating shaft is fixed, and the rollers can roll around the rotating shaft or swing laterally along it; the rubber blocks are generally 1-2cm long and are used to restrict the axial movement of the rollers on the rotating shaft, preventing hard contact between the rollers and the support frames, and adjusting the position of the rubber blocks on the rotating shaft. Adjust the position of the rubber blocks on the rotating shaft as needed, so that the rollers located between the rubber blocks are on the straight line of the set position of the slide rail, thus ensuring that the bridge inspection vehicle track on the slide rail is in the designed installation position.

[0046] After the roller position is adjusted to be correct, the bridge inspection vehicle track is connected to the bottom of the bridge beam to complete the installation of the track beam (during the fine-tuning stage, personnel use a hanging basket to reach the designated position).

[0047] S4: Remove the rolling structure and support frame.

[0048] If multiple bridge inspection vehicle tracks are installed on the bridge, then multiple sets of the aforementioned steel structure bridge inspection vehicle track installation devices shall be installed.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
