Description

Technical Field

[0001] This utility model relates to the field of track engineering equipment technology, and in particular to a general-purpose track panel lifting and adjusting device. Background Technology

[0002] The common scheme for assembling rail panels on the ground at the track-laying base and transporting them to the tunnel working face for overall lifting involves ordinary long sleeper rail panels and trapezoidal sleeper rail panels. In general monolithic track sections, ordinary long sleepers are used to assemble rail panels, and a rail panel adjustment bracket with a total length of 2.2m and a screw support hole spacing of 2.035m is used for track panel lifting and geometric dimension adjustment. In high-vibration-damping track sections, trapezoidal sleepers are used to assemble 25m rail panels, and a rail adjustment bracket with a total length of 2.42m and a screw support hole spacing of 2.315m is used for track panel lifting and geometric dimension adjustment. The support distance varies for different models and specifications of rail panels, and the tooling for lifting and adjusting rail panels is custom-made for each model and specification. Urban rail transit track engineering is a municipal project, and construction generally takes place in urban areas. On-site storage space and underground working space are limited, and construction time is constrained by the urban environment. The diverse structures of ground buildings also lead to increased variations in track bed design. The existing construction plan uses two different construction tools for the same process, which increases the time and space required for construction turnover, increases the need for on-site material storage, and the frequent handling of tools also increases safety risks. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a universal track panel lifting and adjusting device that can be applied to track panel operations of different specifications and models, avoiding the risk of relocation caused by frequent tooling changes.

[0004] The purpose of this utility model is achieved through the following technical solution: a universal rail panel lifting and adjusting device, comprising a supporting horizontal plate and side supporting plates arranged at both ends of the supporting horizontal plate, a positioning plate for connecting the supporting horizontal plate and the side supporting plates, multiple lifting rods for adjusting the lifting height, and an adjusting assembly for adjusting the track gauge. A gap is provided between the supporting horizontal plate and the side supporting plates. The two ends of the positioning plate are respectively fixed to the bottom surfaces of the supporting horizontal plate and the side supporting plates. The area of ​​the positioning plate located in the gap is a positioning surface. The positioning surface, the side surface of the supporting horizontal plate, and the side surface of the side supporting plates form a rail support platform for mounting the rails. Multiple adjusting sleeves corresponding one-to-one with the lifting rods are provided on the side supporting plates. The adjusting assembly consists of a first limiting block installed on the side supporting plate, a second limiting block installed on the supporting horizontal plate, and a bolt assembly for holding the rails in place. The first limiting block is arranged flush with the side supporting plate, and the second limiting block is offset towards the center along the side surface of the supporting horizontal plate (not flush with the edge, leaving room for rail adjustment). Both the first and second limiting blocks are provided with threaded holes for installing the bolt assembly.

[0005] The positioning surface is provided with a rail bottom slope of 1:40. This appropriate slope concentrates the wheel-rail contact at the top of the rail and the center of the wheel tread, resulting in less axial force on the rail and less lateral biasing stress. This also reduces the additional bending stress at the rail web, improving the rail's lateral stability. Multiple adjusting sleeves are arranged on the same straight line, each corresponding to a different rail panel specification. The distance from the center of one adjusting sleeve to the center of the rail corresponds to the width of a rail panel specification. In this design, the distance from the center of the adjusting sleeve to the center of the rail is the width of the corresponding rail panel. Although the rail panel widths differ, they all conform to national standards and are fixed. Multiple adjusting sleeves can be installed on one side support plate. The lifting rod has threads for raising and lowering, and the adjusting sleeve has threaded grooves corresponding to the lifting rod threads. The threaded holes on the first and second limiting blocks are at the same height. Adjustment components are arranged on both sides of the support plate. The second limiting block is offset from the center along the side of the supporting cross plate by 15-25mm. The bolt assembly includes a first screw passing through the first limiting block and a second screw passing through the second limiting block. The first and second screws respectively abut against the rail webs on both sides of the rail, and the track gauge between the rails is adjusted by the screws (first and second screws) on both sides of the rail web.

[0006] This application addresses the shortcomings of existing construction methods by specifically resolving the need for two separate material storage areas on the ground during construction, the need for tool turnover, and the potential safety risks during the turnover process. Its working principle is to combine two (or more) rail adjustment supports into one, allowing the same track lifting and gauge adjustment tooling to be used for the same construction process under different track bed types. Different track lifting rods are used to match different specifications of rail panels, and the track gauge is adjusted by the adjustment components on both sides of the supporting crossbar, completing track lifting and gauge adjustment with a single set of tooling.

[0007] The beneficial effects of this utility model are: adjustment components for adjusting track gauge are provided on both sides of the support plate, and multiple adjustment sleeves and track lifting rods corresponding to different specifications of track panels are provided on the side support plates on both sides of the support plate, realizing track panel operation applicable to different specifications and models, and completing the track gauge adjustment operation and track lifting operation through a set of tooling, avoiding the risk of relocation caused by frequent tooling changes.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] like Figures 1-4As shown, a general-purpose track-raising and adjusting device includes a supporting horizontal plate 1 and side supporting plates 2 arranged at both ends of the supporting horizontal plate 1. It also includes a positioning plate 3 for connecting the supporting horizontal plate 1 and the side supporting plates 2, multiple track-raising rods 4 for adjusting the track-raising height, and an adjusting assembly 5 for adjusting the track gauge. A gap 7 is provided between the supporting horizontal plate 1 and the side supporting plates 2. Both ends of the positioning plate 3 are fixed to the bottom surfaces of the supporting horizontal plate 1 and the side supporting plates 2, respectively. The area of ​​the positioning plate 3 located in the gap 7 is a positioning surface 301. The positioning surface 301, the side surface of the supporting horizontal plate 1, and the side supporting plate 2... A rail support platform 8 for mounting the rail 6 is formed on the side. The side support plate 2 is provided with a plurality of adjusting sleeves 201 corresponding one-to-one with the track lifting rod 4. The adjusting assembly 5 consists of a first limiting block 501 mounted on the side support plate 2, a second limiting block 502 mounted on the support cross plate 1, and a bolt assembly 503 for holding the rail 6 in place. The first limiting block 501 is arranged flush with the side support plate 2, and the second limiting block 502 is arranged offset towards the center along the side of the support cross plate 1. Both the first limiting block 501 and the second limiting block 502 are provided with threaded holes 302 for mounting the bolt assembly 503.

[0015] The positioning surface 301 is provided with a rail bottom slope. The rail bottom slope is 1:40. The centers of the multiple adjusting sleeves 201 are arranged on the same straight line. The track lifting rod 4 is provided with threads for lifting, and the adjusting sleeve 201 is provided with threaded grooves corresponding to the threads of the track lifting rod 4. The threaded holes 302 on the first limiting block 501 and the threaded holes 302 on the second limiting block 502 are at the same height. The multiple adjusting sleeves 201 correspond to different specifications and models of rail panels, and the distance from the center of one adjusting sleeve 201 to the center of the rail corresponds to the width distance of one specification and model of rail panel. The offset distance of the second limiting block 502 from the side of the supporting cross plate 1 towards the center is 15-25mm. The bolt assembly 503 includes a first screw 504 passing through the first limiting block 501 and a second screw 505 passing through the second limiting block 502, wherein the first screw 504 and the second screw 505 respectively abut against the rail web on both sides of the rail 6.

[0016] In this application, the dimensions of the formed rail support platform 8 are 460mm in length, 140mm in width, and 20mm in thickness. The base of the positioning plate 3 has 8 bolt holes evenly distributed for positioning the plate 3 and supporting the horizontal plate 1 and the side support plate 2. Adjustment components 5 are arranged on both sides of the supporting horizontal plate 1, and two rail support platforms 8 are also arranged on the corresponding sides of the supporting horizontal plate 1.

[0017] The supporting horizontal plate 1 is a rectangular steel plate with a length of 1330mm, a width of 40mm, and a height of 80mm. The positioning plates 3 on both sides of the supporting horizontal plate 1 are steel plates with a length of 150mm, a width of 140mm, and a thickness of 10mm. On both sides of the supporting horizontal plate 1, 20mm from the edge, a steel block with a length of 40mm, a width of 25mm, and a height of 45mm is welded as a second limiting block 502. The second limiting block 502 has a bolt hole with a diameter of 20mm in the middle. In use, a second screw 505 is screwed in to limit the inward movement of the rail 6, preventing the rail 6 from shifting inward. The supporting horizontal plate 1 serves to connect the two side supporting plates 2 and limit the inward movement of the rail 6, making the entire device a whole.

[0018] The side support plate 2 is made of a rectangular steel plate with a length of 365mm, a width of 40mm, and a height of 80mm. A hollow ring with an inner diameter of 35mm, an outer diameter of 65mm, and a height of 80mm is welded in the middle as an adjusting sleeve 201. The hollow steel ring is threaded inside so that the track lifting rod 4 can be screwed in. The center of the inner ring is 172.5mm from the inner edge of the side support rod, and the center of the outer ring is 312.5mm from the inner edge of the side support rod, to accommodate two different widths of track panels: ordinary long sleepers and trapezoidal sleepers. A limiting steel block with a length of 40mm, a width of 25mm, and a height of 45mm is welded to the inner edge of the side support plate 2 as a first limiting block 501. The first limiting block 501 has a bolt hole with a diameter of 20mm in the middle. When in use, the first screw 504 is screwed in to limit the outer side of the rail 6 to prevent the rail 6 from shifting outward. The side support plate 2 serves to support the overall track panel, lift the track, adjust the rail, and limit the outward shift of the rail. The hollow ring can be screwed into a universal screw rod used in subway construction. The functions of track panel support, track panel elevation adjustment, and track panel superelevation adjustment are achieved by the cooperation between the hollow ring and the screw rod.

[0019] During the track panel lifting process, this solution can be used to lift and adjust both ordinary long sleeper track panels and trapezoidal sleeper track panels. The lifting rod 4 is used to pass through the reserved hole corresponding to the width of the track panel. By turning the lifting rod 4, the lifting amount and superelevation of the track panel can be adjusted. Bolts are screwed into the reserved bolt holes of the limiting steel block to restrict the lateral displacement of the rail and adjust the track gauge. When adjusting the track panel, the geometric dimensional accuracy of track gauge, direction, superelevation and other dimensions can reach within 1mm.
