Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel concrete segment prefabrication, and in particular relates to a detachable cone fixing device. Background Art

[0002] The shield segment is the main assembly component of the shield tunnel construction. As the innermost protective structural barrier of the tunnel, it bears the role of resisting soil pressure, groundwater pressure and some special loads. The production of shield segments usually uses high-strength impermeable concrete to ensure reliable bearing and waterproof performance. In the production process, the finished segment mold can be formed after sealing and pouring concrete. The segment mold is made of mold steel. It is a special concrete prefabricated mold for tunnel segment production consisting of a bottom mold, four side plates and two cover plates. In some projects, the segment needs to have a conical hole for assembly and positioning, so a cone part will be installed on the side plate of the mold. After the segment is cast, a conical hole will be formed on the segment. The segments of different sections of the same project have two segment designs: conical holes for assembly and positioning and conical holes without assembly and positioning. Therefore, it is necessary to design a detachable cone fixing device on the mold to meet the needs of different segment designs.

[0003] At present, the common connection method of mold cones in the market is to connect directly to the side plate through threads. This structure requires the cone parts to be completely removed when disassembling them, which is inconvenient to operate and cannot meet the requirements of casting segments with and without cone holes on the same mold, which increases the cost for customers when using the mold. Therefore, a detachable cone fixing device is proposed. Utility Model Content

[0004] The utility model aims to provide a detachable cone fixing device, aiming to solve the problems raised in the above background technology.

[0005] The embodiment of the utility model is implemented as follows: a detachable cone fixing device includes a cone member and further includes:

[0006] A stop ring, wherein the cone member is welded to the stop ring;

[0007] Cone support assembly;

[0008] A bolt, wherein the bolt is threadedly connected to the cone support assembly, and the bolt is fixedly connected to the cone member;

[0009] Flanges;

[0010] Connector 1, the connector 1 is used to connect the cone support assembly with the mold side plate;

[0011] Connecting piece 2, the connecting piece 2 is used to connect the flange piece with the mold side plate.

[0012] Furthermore, the cone support assembly comprises:

[0013] A cone support ring, wherein the cone support ring is threadedly connected to the bolt;

[0014] The cone support tube, the cone support ring is welded to the cone support tube, and the cone support tube is connected to the mold side plate through a connecting piece.

[0015] Furthermore, a stop ring is welded on the cone member.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The detachable cone fixing device can eliminate the need to completely remove the cone part when demoulding the pipe segment. The installation operation is quick and convenient. It also solves the problem that a set of molds needs to be switched to produce pipe segments with and without tapered holes during the casting process, reducing the cost for customers when using molds.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-4 As shown, a detachable cone fixing device provided by an embodiment of the utility model includes a cone member 1 and also includes:

[0026] A stop ring 2, wherein the cone member 1 is welded to the stop ring 2;

[0027] A cone support assembly, the cone support assembly comprises a cone support ring 3 and a cone support tube 6, the cone support ring 3 is welded to the cone support tube 6;

[0028] Bolt 4, the cone support ring 3 is threadedly connected with the bolt 4, and the bolt 4 is fixedly connected with the cone member 1;

[0029] Flange 5;

[0030] A connecting piece 7, wherein the connecting piece 7 is used to connect the cone support tube 6 to the mold side plate;

[0031] A second connecting member 8, wherein the second connecting member 8 is used to connect the flange member 5 to the mold side plate;

[0032] In the embodiment of the utility model, the detachable cone fixing device is connected to the mold side plate by connecting piece 1 7 and connecting piece 2 8, and the cone member 1 is installed and positioned on the mold side plate by rotating bolt 4. When the segment is demoulded, the cone member 1 can be removed from the mold by rotating bolt 4, and the operation can be completed without completely removing the cone member 1. In addition, it is also possible to cast a segment without a conical hole. A segment without a conical hole is a segment type that can be cast by Figure 4 The steel plug 11 parts in the cone 1 are replaced by the cone 1, so that a set of molds can produce two different types of pipe segments. By removing the connecting piece 1 7 and the connecting piece 2 8, the detachable cone fixing device can be quickly removed.

[0033] The working principle of the utility model is:

[0034] The detachable cone fixing device is connected to the mold side plate by connecting piece 1 7 and connecting piece 2 8, and then the cone member 1 is installed and positioned on the mold side plate by rotating bolt 4. Different from the structure in which the cone member 1 is directly connected to the mold side plate by thread, the detachable cone fixing device only needs to rotate bolt 4 to withdraw the cone member 1 from the mold during the demoulding operation of the pipe segment, and the cone member 1 does not need to be completely removed to complete the operation. The installation operation of the cone member 1 is fast and convenient, and the pipe segment without a tapered hole can also be cast. By removing connecting piece 1 7 and connecting piece 2 8, the detachable cone fixing device is quickly removed, which solves the problem of quickly switching between casting pipe segments with tapered holes and those without tapered holes on the same mold.

[0035] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
