Technical Field

[0001] The utility model relates to auxiliary equipment for subway track construction, in particular to a running track support frame with adjustable track gauge and elevation. Background Art

[0002] Track laying gantry crane is a commonly used equipment for subway track laying. Its main function is to hoist track structures such as rails and track plates or components such as rails and fasteners to the laying site. The track laying gantry crane runs on the running rails on the left and right sides. The running rails are installed with brackets and are generally installed on the shield segments by drilling holes or combining pre-embedded slideways in the segments.

[0003] Since the shield tunneling sections of each subway line or section vary in size and track structure size, the installation height of the running rails and the track gauge after installation are also different. Since the span of the gantry crane cannot be changed, the construction party needs to use different gantry cranes and matching running rails when constructing different lines, which leads to problems such as increased construction costs.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0025] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-Figure 5 As shown, the utility model comprises a support assembly 2 fixed to a shield segment 1, which is provided with a horizontal support surface;

[0027] A telescopic sleeve 3 is vertically arranged on the support surface to achieve the effect of adjusting the height of the running rail 4;

[0028] A running rail 4 is installed on the top of the telescopic sleeve 3, a transverse sliding structure is provided between the running rail 4 and the telescopic sleeve 3, and a fixed structure is provided between the running rail 4 and the telescopic sleeve 3. The transverse relative position of the running rail 4 and the telescopic sleeve 3 can be moved by the transverse sliding structure and fixed by the fixed structure, so as to achieve the effect of adjusting the track gauge.

[0029] Specifically, the support assembly 2 includes an arc-shaped mounting side plate 201 fixed on the shield segment 1 by mounting side plate bolts 202, and a horizontally arranged support platform 203 arranged on the mounting side plate 201, a support rib 204 is arranged between the support platform 203 and the mounting side plate 201, and the support platform 203, the mounting side plate 201, and the support rib 204 are connected by welding, and the support surface is formed with the upper surface of the support platform 203. This embodiment has the advantages of simple structure and high strength.

[0030] Specifically, the telescopic sleeve 3 includes a lower sleeve 301 welded on the support platform 203, and an upper sleeve 302 inserted in the lower sleeve 301, a plurality of latch holes are reserved on the upper sleeve 302, and a plurality of latch holes are also reserved on the lower sleeve 301, and a latch is inserted into the latch hole to connect the upper sleeve 302 and the lower sleeve 301, and the relative position of the latch and the latch hole is adjusted to achieve the effect of adjusting the elevation of the running rail 4. This embodiment has the advantages of simple structure and durability.

[0031] Specifically, the transverse sliding structure includes a rail plate 5 welded to the top of the upper sleeve 302 and a slide groove 501 provided on the rail plate 5, and the fixing structure includes a rail clip 502, a rail plate bolt 503, and a nut. The rail clip 502 is crimped onto the running rail 4, and the rail plate bolt 503 passes through the slide groove 501 on the rail plate 5 and is then locked with a nut, thereby fixing the rail clip 502 to the rail plate 5. The principle of this embodiment is to connect the running rail 4 to the rail plate 5 by using the rail plate bolt 503, and to reserve a slide groove 501 on the rail plate 5 for moving the lateral relative position of the running rail 4 and the rail plate 5, so as to achieve the effect of adjusting the track gauge. This embodiment has the advantages of simple structure and durability.

[0032] As a preferred embodiment, considering the heavy weight of the running rail 4 and the difficulty in operation, the support platform 203 has an operating platform 203a extending laterally, and the operating platform 203a can be used to carry a jacking device 7 such as a hydraulic jack (such as Figure 4 When adjusting the height, a hydraulic jack can be placed under both ends of a running rail 4 to lift the running rail 4 to a predetermined height, and then adjust the telescopic sleeve 3, which can greatly reduce the difficulty of operation when adjusting the height of the running rail 4.

[0033] As a preferred embodiment, based on the same consideration, the rail support plate 5 has bolt interfaces 5a at both ends of the slide groove 501, and the bolt interfaces 5a can be connected to the transverse adjustment bolts 6; when adjusting the track gauge, the transverse adjustment bolts 6 can be installed on the bolt interfaces 5a at both ends of a section of the running rail 4, the rail support plate bolts 503 are loosened, and then the transverse adjustment bolts 6 are adjusted (such as Figure 5 ), the lateral adjustment bolt 6 can be rotated by a wrench operation to press against the side of the running rail 4 and then push the running rail 4 to move to adjust the track gauge. This can not only reduce the difficulty of operating when adjusting the track gauge of the running rail 4, but also accurately adjust the track gauge and straighten the running rail 4.
