Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a supporting tooling structure for the foundation of a tunnel steel spring floating slab track bed. Background Technology

[0002] The supporting tooling structure for the foundation of tunnel steel spring floating slab track bed is a supporting tooling system used for foundation treatment during the construction of tunnel steel spring floating slab track bed. It provides positioning, support, and formwork fixing functions for the excavation, cleaning, leveling, reinforcement installation and concrete pouring of the floating slab track bed foundation, ensuring the accuracy and stability of foundation construction.

[0003] During construction, when workers need to adjust the position of the base elevation clamp, they manually loosen the nut so that the nut and the bracket no longer clamp the base elevation clamp, and then adjust the position by moving the base elevation clamp by hand.

[0004] The existing technology has the following drawbacks: it is impossible to adjust the two sets of base elevation clamps at the same time. If it is necessary to adjust the position of the two sets of clamps at the same time, they can only be operated one by one. This not only consumes a lot of time, but also easily causes new positional deviations due to the asynchronous adjustment of each set, which seriously restricts the construction progress and makes it difficult to guarantee the overall accuracy of the base elevation. Therefore, a supporting tooling structure for the base of the tunnel steel spring floating slab track bed is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tooling structure for the foundation of a tunnel steel spring floating slab track bed, aiming to solve the problem of cumbersome foundation elevation clamping adjustment steps in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tooling structure for the base of a tunnel steel spring floating slab track bed, comprising a support, a connecting rod provided on the inner wall of the support, an arc-shaped block contacting the bottom end of the connecting rod, a threaded rod rotatably connected to the inner wall of the support, a connecting plate threadedly connected to the outer wall of the threaded rod, a slider hinged to the inner wall of the connecting plate via a hinge rod, a base elevation clamp contacting the inner wall of the slider, and a nut threadedly connected to the outer wall of the base elevation clamp.

[0007] As a further description of the above technical solution:

[0008] The inner wall of the arc-shaped block is threaded with bolts, and the inner wall of the arc-shaped block is fixedly connected with a rubber pad.

[0009] As a further description of the above technical solution:

[0010] A bottom end of the nut is in contact with a top end of the sliding block, and a rectangular opening is provided inside the bracket.

[0011] As a further description of the above technical solution:

[0012] The sliding block is slidably connected to an inner wall of the bracket.

[0013] As a further description of the above technical solution:

[0014] An inner wall of the connecting plate is hinged to one end of a hinge rod, and the other end of the hinge rod is hinged to an inner wall of the sliding block.

[0015] As a further description of the above technical solution:

[0016] The bolt is threadedly connected to an inner wall of the connecting rod.

[0017] The present utility model has the following beneficial effects:

[0018] 1. In the present utility model, by manually loosening or tightening the nut, the position of a single set of foundation elevation fixture can be adjusted individually and flexibly, and by rotating the threaded rod clockwise or counterclockwise, two sets of foundation elevation fixtures can be synchronously driven to separate from or approach each other, so that the precise adjustment of the positions of the foundation elevation fixtures can be quickly realized, and the adjustment efficiency is greatly improved.

[0019] 2. In the present utility model, when replacing the arc block, the old block can be removed only by manually unscrewing the bolt, and the fixation can be completed by aligning the notch and tightening the bolt during new installation, which has simple and quick steps. This design can flexibly replace a suitable arc block according to different pipeline conditions, significantly enhance the adaptability of the device to various pipelines and improve the use flexibility.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a tooling structure for a tunnel steel spring floating slab track bed base, including a support 1. The support 1 supports the entire device. A connecting rod 2 is provided on the inner wall of the support 1, and the connecting rod 2 connects to an arc-shaped block 3. The bottom end of the connecting rod 2 contacts the arc-shaped block 3. The connecting rod 2 is provided with the same number of nuts 11 as the base elevation clamp 10. A threaded rod 9 is rotatably connected to the inner wall of the support 1. The support 1 has a groove corresponding to the smooth surface of the threaded rod 9 to facilitate the rotation of the threaded rod 9. The outer wall of the threaded rod 9 is threadedly connected to a connecting plate 8. The connecting plate 8 is provided with threads that match the threaded rod 9. The inner wall of the connecting plate 8 is hinged to a slider 6 via a hinge rod 7. The inner wall of the slider 6 contacts a base elevation clamp 10. The outer wall of the base elevation clamp 10 is threadedly connected to a nut 11. A round rod is provided on the upper part of the base elevation clamp 10. The round rod is provided with threads that match the nut 11. Two sets of nuts 11 are provided on the round rod. By turning the upper set of nuts 11, the position of the base elevation clamp 10 can be restricted.

[0028] Reference Figure 1 , Figure 2 and Figure 4 The inner wall of the arc-shaped block 3 is threaded with a bolt 5, and the arc-shaped block 3 is provided with a thread that matches the bolt 5. The inner wall of the arc-shaped block 3 is fixedly connected with a rubber pad 4, and the rubber pad 4 is provided with multiple sets of small protruding particles, which can increase the friction between the arc-shaped block 3 and the central pipe. The bolt 5 is threaded on the inner wall of the connecting rod 2, and the connecting rod 2 is provided with a thread that matches the bolt 5.

[0029] Reference Figures 1-3The bottom end of nut 11 contacts the top end of slider 6. A rectangular opening is provided inside the bracket 1 so that the hinge rod 7 is not obstructed when it deflects. Slider 6 is slidably connected to the inner wall of bracket 1. Slots corresponding to slider 6 are provided on bracket 1 to facilitate the left and right movement of slider 6. The inner wall of connecting plate 8 is hinged to one end of hinge rod 7, and the other end of hinge rod 7 is hinged to the inner wall of slider 6. Since the length of hinge rod 7 is fixed, when connecting plate 8 moves forward with one end of hinge rod 7, the other end of hinge rod 7 will separate the two sets of sliders 6. When connecting plate 8 moves backward with one end of hinge rod 7, the other end of hinge rod 7 will bring the two sets of sliders 6 closer together.

[0030] Working principle: When it is necessary to adjust the position of a set of base elevation clamps 10, manually loosen the upper set of nuts 11 so that the nuts 11 no longer restrict the position of the base elevation clamps 10. Then, manually move the base elevation clamps 10 left and right to adjust their position on the slider 6. When the position adjustment is complete, manually tighten the nuts 11 so that the upper set of nuts 11 contacts the slider 6 and clamps the base elevation clamps 10. When it is necessary to adjust the position of two sets of base elevation clamps 10 at the same time, manually rotate the threaded rod 9 clockwise. When the connecting plate 8 moves forward with the hinge rod 7, the other end of the hinge rod 7 will move the two sets of... When the sliders 6 separate, the position of the base elevation clamp 10 is changed. When the threaded rod 9 is manually rotated counterclockwise, the connecting plate 8 moves backward with the hinge rod 7. The other end of the hinge rod 7 will bring the two sets of base elevation clamps 10 closer together, thereby changing the position of the base elevation clamps 10. When it is necessary to adjust the height position of the base elevation clamps 10, manually loosen the two sets of nuts 11 on the set of base elevation clamps 10, and then manually adjust the height position of the base elevation clamps 10. After the adjustment is completed, manually tighten the two sets of nuts 11 so that the two sets of nuts 11 clamp the slider 6, thus completing the limitation of the base elevation clamps 10.

[0031] When the arc block 3 needs to be replaced, manually unscrew the bolt 5. When the bolt 5 separates from the connecting rod 2, manually remove the arc block 3. Then, the staff can replace the appropriate arc block 3 according to the pipeline conditions. At this time, the staff needs to align the bolt 5 with the groove on the connecting rod 2, and then tighten the bolt 5 to complete the connection between the arc block 3 and the connecting rod 2.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
