Description

Technical Field

[0001] The utility model relates to the technical field of pipe segment production, in particular to an adjustable pipe segment mould. Background Art

[0002] The shield segment is the main assembly component of the shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel.

[0003] At present, segment molds are produced according to the demand orders provided by users, and their width cannot be adjusted. Tunnels vary in length. At the end of tunnel construction, it is inevitable that the segment length will not be consistent with the remaining size of the tunnel, resulting in the segment being unable to be installed. This has low practicality and requires subsequent customization of molds of corresponding sizes or manual processing, which is cumbersome and greatly reduces construction efficiency. Therefore, we propose an adjustable segment mold. Utility Model Content

[0029] Example 1

[0030] like Figure 1-4 As shown, the utility model provides a technical solution: an adjustable segment mold, comprising a base 1, a casting mechanism 2 is arranged at the top of the base 1, the casting mechanism 2 comprises a bottom plate 201, side plates 202 are symmetrically arranged on the left and right sides of the bottom plate 201, a guide rail 203 is opened at the top of the side plate 202, a slider 204 is arranged inside the guide rail 203, a slide groove 205 is opened near the top of the outer side of the side plate 202, a first threaded rod 206 is arranged inside the slide groove 205, and the side plate 201 is provided with a first threaded rod 206. A fixing block 207 is provided on the inner side of 02 near the back side, a first threaded opening 208 is provided on the front side of the fixing block 207 near the bottom, a second threaded rod 209 is provided inside the first threaded opening 208, a rotating shaft 210 is provided on the front side of the second threaded rod 209 and at the top end of the bottom plate 201, a fixing plate 211 is provided on the front side of the bottom plate 201 and at the front side of the side plate 202, and a movable plate 212 is provided on the top end of the bottom plate 201 near the back side and between the two side plates 202.

[0031] Example 2

[0032] like Figure 1-4 As shown, the bottom plate 201 is fixed to the base 1 by bolts, and the side plate 202 and the fixing plate 211 are fixed to the bottom plate 201 by bolts.

[0033] The bolt fixation of the bottom plate 201 and the side plate 202 with the fixed plate 211 can improve the overall stability of the casting mechanism 2, and at the same time, it can facilitate the disassembly and cleaning of the parts of various parts of the casting mechanism 2. The slider 204 is slidably connected to the guide rail 203, the slider 204 is welded to the movable plate 212, and the first threaded rod 206 is slidably connected to the slide groove 205. The slider 204 can drive the movable plate 212 to slide back and forth inside the guide rail 203, so that the width of the pipe segment can be adjusted as needed to improve practicality. The first threaded rod 206 is slidably connected to the slide groove 205, and the position of the first threaded rod 206 is moved according to the position of the slider 204. The outer side of the slider 204 is provided with a second threaded opening 213 corresponding to the first threaded rod 206. The threaded rod 206 is adapted to the second threaded opening 213. By adapting the first threaded rod 206 to the second threaded opening 213, the first threaded rod 206 can be rotated to fix the slider 204, thereby achieving the purpose of fixing the movable plate 212. The fixed block 207 is welded to the side plate 202, and the second threaded rod 209 is adapted to the first threaded opening 208. By welding the fixed block 207 to the side plate 202, the fixed block 207 can be made more stable, thereby improving the overall stability. By rotating the second threaded rod 209, the bottom of the movable plate 212 can be fixed. The rotating shaft 210 is fixedly connected to the second threaded rod 209, and the movable plate 212 is fixedly connected to the rotating shaft 210. The rotating shaft 210 can make the second threaded rod 209 rotate more smoothly, thereby improving the convenience of use.

[0034] The working process of the utility model is as follows: when an adjustable segment mold is used for segment casting, the segment steel frame is first welded according to the required size, the welded segment steel frame is placed on the top of the bottom plate 201, and the front of the steel frame is aligned with the back of the fixed plate 211, and the movable plate 212 is pushed to slide toward the steel frame inside the guide rail 203 under the action of the slider 204 until the front of the movable plate 212 is aligned with the back of the steel frame. The width of the segment can be adjusted according to the use requirements, which greatly improves the practicality and eliminates the cumbersome steps of manual processing and customized molds in the later stage. The construction efficiency is effectively improved. The first threaded rod 206 is rotated to make it spirally rotate into the second threaded opening 213, thereby fixing the slider 204 and the movable plate 212. The second threaded rod 209 is rotated to make it spirally rotate forward inside the first threaded opening 208. The rotational connection between the second threaded rod 209 and the movable plate 212 can be achieved through the rotating shaft 210, which can make the second threaded rod 209 rotate more smoothly, completing the reinforcement of the bottom of the movable plate 212 and completing the entire fixing process. Finally, concrete grouting is carried out through external equipment to complete the casting production of the pipe segment.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
