Description

Technical Field

[0001] The utility model relates to the technical field of tunnel engineering, in particular to a pull-out arch sealing device for a lining trolley. Background Art

[0002] Tunnel lining refers to a permanent structure that supports and maintains the long-term stability and durability of the tunnel. Its function is to support and maintain the stability of the tunnel, maintain the space required for train operation, prevent weathering of the surrounding rock, and relieve the influence of groundwater. Therefore, the tunnel lining must have sufficient strength, durability, and certain anti-freeze, anti-seepage and anti-corrosion properties.

[0003] Lining arch sealing refers to the process of pouring, sealing and filling the gaps in the top arch range that are not filled with concrete and the reserved entrance and exit windows before the top arch concrete is poured during tunnel construction. With the rapid development of current tunnel engineering technology, the safety hazards caused by the problem of tunnel lining arch voids have received more and more attention from the engineering industry, and have also become a difficult problem in tunnel lining arch construction quality control.

[0004] The existing lining arch sealers still have the following shortcomings: 1) During the construction of the traditional lining arch, the position of the concrete pouring pipe is very likely to cause leakage, and the appearance quality is poor. 2) The existing lining arch sealers only rely on the reserved grouting holes on the arch of the lining trolley to fill the lining arch with mold grouting to make up for the lining arch hollow defect, but the effect is not good.

[0005] It can be seen that the existing lining arch sealer still has problems such as leakage, poor appearance quality, and poor grouting effect of the reserved grouting holes with molds. Utility Model Content

[0006] The utility model aims to provide a pull-out arch sealer for a lining trolley, which controls slurry leakage, improves the appearance, controls the casting quality of the lining arch, and can be used permanently as the trolley moves, has low cost, simple operation and improved efficacy.

[0007] To achieve the above-mentioned purpose, the utility model provides a pull-out arch sealer for a lining trolley, comprising a cover plate, the cover plate is fixedly arranged on the lining trolley panel, a perfusion pipe is fixedly arranged on the cover plate, a fixing rod is arranged on the outer side of the perfusion pipe, a block is arranged on the lining trolley panel, a pull-out sealing plate is arranged between the cover plate and the lining trolley panel, a base is arranged on the pull-out sealing plate, a connecting rod is arranged on the base, and an operating handle is fixedly connected to the other end of the connecting rod.

[0008] Preferably, the cover plate is connected to the lining trolley panel by fixing bolts.

[0009] Preferably, the cover plate is connected to the perfusion pipe by welding, and the operating handle is welded to the perfusion pipe into a whole.

[0010] Preferably, the stopper is connected to the lining trolley panel by welding, and there are two stoppers, which are arranged on opposite sides of the pull-out sealing plate.

[0011] Preferably, a 2 mm gap is reserved between the pull-out sealing plate and the cover plate, and the pull-out sealing plate is slidably connected to the cover plate.

[0012] Preferably, the base and the pull-out sealing plate are welded into a whole.

[0013] Preferably, the connecting rod is rotatably connected to the base via a hinge, and the connection between the connecting rod and the operating handle is hinged to the other end of the fixing rod.

[0014] Therefore, the utility model adopts a lining trolley pull-out arch sealer of the above structure, which has the following advantages:

[0015] (1) The cover plate is firmly connected to the lining trolley panel through fixing bolts, and the arch sealer can move with the lining trolley and is easy to remove;

[0016] (2) The stopper can limit the position movement of the pull-out plugging plate when it is pulled out before the lining trolley is demoulded;

[0017] (3) The use of this new technology can prevent the problem of tunnel arch being hollowed out and improve the construction quality of tunnel lining arch.

[0026] Example

[0027] like Figure 1-3 As shown, the utility model provides a pull-out arch sealer for a lining trolley, comprising a cover plate 1, which is fixedly arranged on a lining trolley panel 2, and the cover plate 1 is connected to the lining trolley panel 2 by fixing bolts 9. The cover plate 1 is firmly connected to the lining trolley panel 2 by fixing bolts 9, and is permanently used, and moves with the trolley with the lining, so that it is easy to remove.

[0028] The cover plate 1 is fixedly provided with a perfusion pipe 3, and the cover plate 1 is welded to the perfusion pipe 3. A fixing rod 10 is arranged outside the perfusion pipe 3, and the fixing rod 10 is welded to the perfusion pipe 3 as a whole to limit the movement of the operating handle 4.

[0029] A stopper 5 is provided on the lining trolley panel 2, and the stopper 5 is connected to the lining trolley panel 2 by welding. There are two stoppers 5, which are provided on opposite sides of the pull-out plugging plate 6. The stopper 5 limits the position movement of the pull-out plugging plate 6 when it is pulled out before the lining trolley is demoulded. The side of the stopper 5 close to the pull-out plugging plate 6 is not welded, so as to ensure the flatness of the pull-out plugging plate 6 during the movement process.

[0030] A pull-out plugging plate 6 is provided between the cover plate 1 and the lining trolley panel 2. The pull-out plugging plate 6 is slidably connected to the cover plate 1. A 2 mm gap is reserved between the pull-out plugging plate 6 and the cover plate 1 to facilitate the movement of the pull-out plugging plate 6. A base 7 is provided on the pull-out plugging plate 6. The base 7 is welded to the pull-out plugging plate 6 as a whole to ensure that the base 7 can drive the pull-out plugging plate 6 to slide.

[0031] A connecting rod 8 is provided on the base 7, and the connecting rod 8 is rotatably connected to the base 7 through a hinge. The other end of the connecting rod 8 is fixedly connected to the operating handle 4, and the connecting rod 8 and the operating handle 4 form a whole. The connection between the connecting rod 8 and the operating handle 4 is hinged to the other end of the fixed rod 10, so that the movement of the connecting rod 8 can be controlled by pushing and pulling the operating handle 4.

[0032] When a pull-out arch sealer for a lining trolley of this embodiment is in use, after the arch crown of the tunnel lining trolley is poured, the connecting rod 8 is driven to rotate by the operating handle 4, and the connecting rod 8 drives the pull-out sealing plate 6 to move through the base 7 to seal the concrete pouring port in time.

[0033] A set of lining trolley arch crown adopts four pull-out arch sealers. Each arch sealer drives the pull-out sealing plate 6 through the operating handle 4 to seal the concrete pouring port in time, and seals the concrete seamlessly on the arch crown, ensuring the quality of the arch crown concrete pouring and the appearance quality of the arch crown lining after demolding.

[0034] Therefore, the utility model adopts a lining trolley pull-out arch sealer with the above structure, which controls leakage, improves the appearance, controls the casting quality of the lining arch, and can be used permanently with the trolley. It has low cost, simple operation and improved construction quality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
