Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel concrete segment prefabrication, and in particular relates to a mold cover locking device with a new structure. Background Art

[0002] The shield segment is the main assembly component of the shield tunnel construction. It is the innermost protective structure of the tunnel and 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. The production mainly uses the finished segment mold after sealing and pouring concrete. The segment mold is made of mold steel. It is a special concrete prefabricated mold for tunnel segment production composed of a bottom mold, four side plates and two cover plates. Before the segment is poured and after solidification, the two cover plates need to be opened or closed, so the locking device of the cover plate needs to be safe and reliable and easy to disassemble.

[0003] However, the mold cover locking devices currently on the market generally use a direct tightening method of bolts and pressure plates. This structure has the problem that the bolts are easily lost after being disassembled, and the tightened bolts are easily loosened due to the lack of a relaxation function. Therefore, a mold cover locking device with a new structure is proposed. Utility Model Content

[0010] A spring, one end of which is connected to a bolt, and the other end of which is connected to a retaining ring assembly.

[0011] Furthermore, the retaining ring assembly comprises:

[0012] A retaining ring 1, wherein the retaining ring 1 is welded to the baffle;

[0013] The second retaining ring is welded to the baffle.

[0014] Furthermore, a gasket is welded on the pressing plate, and a through hole is opened on the gasket.

[0015] Furthermore, a limiting groove is provided on the baffle.

[0016] Furthermore, the diameters of the through hole and the limiting groove are both smaller than the diameter of the positioning plate.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The mold cover locking device with this new structure can not only solve the problem that the mold cover fastening bolts are easily lost after disassembly, but also make the disassembly of the cover fastening device more convenient. At the same time, it can also solve the problem of bolt loosening during the use of the mold through the compression force of the spring. BRIEF DESCRIPTION OF THE DRAWINGS

[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 1-3 As shown, a mold cover plate locking device of a new structure is provided in one embodiment of the utility model, and the locking device is used to lock the cover plate and the mold end side plate, and includes:

[0026] Press plate 1;

[0027] A baffle plate 2, wherein the baffle plate 2 is welded to the top of the pressing plate 1, and a limiting groove is provided on the baffle plate 2;

[0028] A gasket 3, wherein the gasket 3 is welded on the pressing plate 1, and a through hole is formed on the gasket 3;

[0029] The retaining ring assembly is welded to the baffle 2; the retaining ring assembly comprises:

[0030] A retaining ring 4, wherein the retaining ring 4 is welded to the baffle 2;

[0031] A second retaining ring 6, wherein the second retaining ring 6 is welded to the baffle 2;

[0032] Bolt 5, the bolt 5 is installed on the baffle 2, and a positioning plate 51 is fixedly connected to the bolt 5; the bolt 5 is used in conjunction with a nut;

[0033] Spring 7, one end of the spring 7 is connected to the bolt 5, and the other end of the spring 7 is connected to the retaining ring 4.

[0034] In the embodiment of the utility model, after the pressing plate 1 is connected to the bolt 5, the cover plate can be pressed against the side plate of the mold end. One end of the spring 7 is connected to the bolt 5, and the other end is connected to the retaining ring 4, which can ensure that the bolt 5 does not loosen when the locking device is locked. At the same time, when the locking device is opened, the rebound force of the spring 7 can quickly reset the bolt 5, making it convenient to open the cover plate.

[0035] The locking device connects the cover plate to the side plate of the mold end. This new structure not only solves the problem that the mold cover plate fastening bolts are easily lost after disassembly, but also makes the disassembly of the cover plate fastening device more convenient. At the same time, it can also solve the problem of bolt loosening during the use of the mold through the compression force of the spring.

[0036] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the present utility model, the diameters of the through hole and the limiting groove are both smaller than the diameter of the positioning plate 51 .

[0037] In the embodiment of the utility model, the baffle plate 2 limits the positioning plate 51 on the bolt 5, so as to prevent the bolt 5 from falling off after the cover plate is opened.

[0038] The working principle of the utility model is:

[0039] The mold cover locking device of the new structure, after the pressing plate 1 is connected with the bolt 5, can press the cover on the mold end side plate. One end of the spring 7 is connected with the bolt 5, and the other end is connected with the retaining ring 4, which can ensure that the bolt 5 does not loosen when the locking device is locked. At the same time, when the locking device is opened, the rebound force of the spring 7 can quickly reset the bolt 5, making it convenient to open the cover.

[0040] 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.
