Description

Technical Field

[0001] The present invention relates to the field of subway construction, and in particular to an adjustable automatic locking mechanism. Background Art

[0002] Existing subway stations and underground diaphragm walls are constructed using cast-in-place methods. This involves pouring concrete slurry around a steel cage. Once the concrete solidifies, it bonds tightly with the cage to form the station's floor slab, wall panel, or underground diaphragm wall. However, this method struggles to ensure the correct concrete mix, and the uncontrollable pouring environment makes it very easy for foreign matter to infiltrate the uncured concrete. This can cause the station or underground diaphragm wall to fail to meet design specifications, creating safety risks for subsequent construction.

[0003] In order to ensure the quality of the station's building and underground continuous walls and improve construction efficiency, it is now planned to prefabricate a number of prefabricated wall panels. The prefabrication factory can control the production environment of the prefabricated wall panels and ensure the precise concrete ratio of the prefabricated wall panels or prefabricated floor slabs.

[0004] When two adjacent floor slabs or wall panels are spliced ​​together, steel bars are generally welded together and then the exposed steel bars are sealed with grouting to form a whole. This splicing method requires waiting for the concrete slurry to solidify and cannot quickly fasten the two floor slabs or wall panels. Summary of the Invention

[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0026] Combine Figures 1 to 4 , the adjustable automatic locking mechanism of the present invention is schematically shown, comprising a locking component 1 and a plug-in component 2.

[0027] like Figures 1 to 3 The locking component 1 includes a hollow first shell 11 and a lock body 12 movably provided on the first shell 11, so that the lock body 12 can move in the first shell 11. The plug-in component 2 includes a hollow second shell 21 and a plug-in component 22 movably provided on the second shell 21. The plug-in component 22 is plate-shaped and can extend or retract from the second shell 21.

[0028] The lock body 12 is provided with an insertion slot 121. A locking member 124 and an opening of the insertion slot 121 to the outside are respectively located at both ends of the insertion slot 121. A guide hole 122 is formed on the inner side wall of the insertion slot 121. A locking assembly and a lock pin 123 that is movably inserted into the guide hole 122 are provided within the lock body 12. The locking assembly includes a locking member 124 movably connected to the lock body 12. The locking member 124 blocks the lock pin 123, forcing the end of the lock pin 123 to exit the insertion slot 121 and be received within the guide hole 122. The lock pin 123 has a received state and a locked state. When the lock pin 123 is in the received state, the lock pin 123 is received in the guide hole 122 and does not enter the insertion slot 121. When the lock pin 123 is in the locked state, the lock pin 123 extends out of the guide hole 122 and enters the insertion slot 121. Of course, a spring 125 may be provided between the lock pin 123 and the lock body 12 . The elastic force of the spring 125 may drive the lock pin 123 to automatically extend out of the guide hole 122 and penetrate into the insertion slot 121 .

[0029] like Figure 4 A lock hole 221 is provided on the connector 22, and a cavity 23 is provided between the fixed end of the connector 22 and the second shell 21. When high-pressure cement slurry is injected into the cavity 23, the high-pressure cement slurry pushes the connector 22 to slide relative to the second shell 21, so that the end of the connector 22 extends out of the second shell 21, and the connector 22 can be inserted into the plug-in slot 121 and push the locking member 124 to give way to the locking pin 123, so that the locking pin 123 extends into the plug-in slot 121 and passes through the lock hole 221, automatically locking the locking component 1 and the connector 2.

[0030] There are multiple guide holes 122, multiple locking pins 123 and multiple locking holes 221, and the number of the three is the same. Among them, multiple guide holes 122 are arranged in a matrix, and correspondingly, multiple locking pins 123 are arranged in an array, and multiple locking holes 221 are arranged in an array.

[0031] Furthermore, one or more guide rails 13 are provided in the first shell 11, and the lock body 12 is movably connected to the guide rails 13. The lock body 12 can slide along the guide rails 13 relative to the first shell 11, so that the position of the plug-in slot 121 on the lock body 12 can be changed to adapt to the construction error of the prefabricated panel or the building body, so that the connector 22 and the plug-in slot 121 between two adjacent prefabricated panels can be docked.

[0032] The cavity 23 is provided with a plurality of interlaced connecting ribs, preferably made of metal. When the cement slurry poured into the cavity 23 solidifies, the solidified cement and the connecting ribs form a reinforced concrete structure, allowing the connector 22 and the second housing 21 to be fixedly connected. The plug-in component 2 also includes a limiting rope 24 and a slider 25 slidably disposed within the second housing 21. The ends of the limiting rope 24 are respectively connected to the second housing 21 and the connector 22. The limiting rope 24 can be used to prevent the connector 22 from detaching from the second housing 21 under the pressure of high-pressure cement slurry. At the same time, when the cement slurry solidifies, the limiting rope 24 made of metal and the cement solidify, also forming a reinforced concrete structure. In addition, the cavity 23 is provided between the slider 25 and the second housing 21, and the connector 22 is disposed on the slider 25. The slider 25 can be provided with multiple parallel connectors 22.

[0033] The locking assembly also includes a connecting plate 126, to which a plurality of locking pins 123 are fixedly connected, with the connecting plate 126 and the locking pins 123 being arranged perpendicularly. Specifically, the spring 125 is connected to one side of the connecting plate 126, and the plurality of locking pins 123 are fixedly connected to the other side of the connecting plate 126. The locking member 124 abuts against the connecting plate 126 to block the locking pins 123. In this embodiment, the locking member 124 is provided with a limiting groove 1241, and one end of the connecting plate 126 is movably embedded in the limiting groove 1241, so that the locking member 124 prevents the connecting plate 126 from moving through the limiting groove 1241, thereby preventing the locking pins 123 from switching to the locked state under the elastic force of the spring 125.

[0034] There are multiple and equal numbers of both the insertion slots 121 and the insertion connectors 22. The multiple insertion slots 121 are arranged in parallel, and the guide holes 122 within the multiple insertion slots 121 are coaxially arranged. The locking pins 123 are inserted through the coaxially arranged guide holes 122. This structure can improve the connection stability between the insertion connector 22 and the lock body 12, allowing the automatic locking mechanism to withstand greater tension.

[0035] To sum up, the adjustable automatic locking mechanism of the present invention pours high-pressure cement slurry into the cavity 23, which can push the connector 22 to extend from the second shell 21. A guide hole 122 is provided in the plug-in slot 121 of the lock body 12, and the locking pin 123 is movably inserted into the guide hole 122. The locking member 124 is located in the lock body 12 and the two are movably connected. Under normal circumstances, the locking member 124 prevents the locking pin 123 from entering the plug-in slot 121. When the connector 22 is inserted into the plug-in slot 121, the connector 22 pushes the locking member 124 to give way to the locking pin 123. The locking pin 123 penetrates the plug-in slot 121 and penetrates the lock hole 221 of the connector 22 to automatically lock the connector 22 and the lock body 12. The automatic locking mechanism can realize the automatic splicing of two adjacent prefabricated panels without manual operation, so as to reduce the working hours consumed in splicing prefabricated panels.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
