Detailed Description
The following embodiments are further described with reference to the drawings and examples, and the following examples are only used to more clearly illustrate the technical solutions of the present invention, but not to limit the scope of the present invention.
As shown in fig. 1 to 7, the formwork stripping device for an end wall formwork of an underground engineering of the present invention comprises a lifting device a, a first module B, and a second module C; the top end of the lifting device A is provided with a first module B or a second module C, and the lifting device A drives the first module B or the second module C to ascend or descend.
The lifting device A comprises a connecting rod 1 and a hollow supporting rod 2, and the connecting rod 1 moves in the hollow supporting rod 2; the connecting rod 1 is connected with the first module B or the second module C; the connecting rod 1 is provided with a pin hole 3, a pin penetrates through the pin hole 3, when the height of the connecting rod 1 is fixed, the pin penetrates through the pin hole 3, and two ends of the pin are supported on the hollow supporting rod 2, so that the connecting rod 1 is prevented from rising or falling.
As an option, the bottom of the connecting rod 1 is provided with a rectangular block 4, the hollow supporting rod 2 is internally provided with an air cylinder or a hydraulic cylinder, a piston rod of the air cylinder is connected with the rectangular block 4, the air cylinder or the hydraulic cylinder drives the connecting rod 1 to ascend and descend, and the rectangular block 4 is convenient for the piston rod of the air cylinder to be connected with the piston rod.
Preferably, the chock 5 is installed at the opening of the hollow support rod 2, the shaft hole is formed in the shaft center of the chock 5, the connecting rod 1 penetrates through the shaft hole, and the setting of the chock 5 can guarantee the stability of the ascending or descending of the connecting rod 1 and simultaneously avoid impurities from falling into the hollow support rod 2.
As another embodiment, the lifting process of the connecting rod 1 adopts the following structure:
the connecting rod 1 is provided with an external thread, an internal thread is arranged in a shaft hole of the chock 5, the connecting rod 1 is screwed with the chock 5 in a matching way, and when the connecting rod 1 needs to ascend or descend, the purpose can be achieved only by turning the connecting rod 1.
