The number of templates is two or three sets, and the length of a single template can be set to 9m or 12m, etc., according to engineering needs. The templates are connected to the trolley via hydraulic cylinders. The templates and the hydraulic cylinders are detachably connected via a first connecting structure. It also includes a second connecting structure for detachably connecting two adjacent sets of templates. The first connecting structure includes a first connecting column 2, rotatably connected to the template via a pin; and a second connecting column 3, fixedly connected to the output shaft of the hydraulic cylinder. The first connecting column 2 and the second connecting column 3 are inserted into each other and are coaxially arranged after insertion. The end of the second connecting column 3 is provided with an insertion part 31, which is cylindrical and coaxially arranged with the second connecting column 3. The end of the first connecting column 2 is provided with... The first connection structure includes a connector 21, which is coaxially arranged with the first connecting post 2. The connector 31 is inserted into the connector 21 and fixed by a pin. The pin is inserted radially into the connector 31 and the connector 21 for fixing. At this time, the connector 31 cannot be dislodged from the connector 21. The first connection structure also includes a pull rope 4 and an electric rope retractor. One end of the pull rope 4 extends into the connector 21 and connects to the first connecting post 2. The other end of the pull rope 4 is connected to the electric rope retractor. The second connecting post 3 and the connector 31 are provided with a first rope groove 32 along the axial direction of the second connecting post 3. The side of the second connecting post 3 is provided with a rope groove outlet 33 connected to the first rope groove 32. The first rope groove 32 and the rope groove outlet 33 form an L-shaped structure. The pull rope 4 enters from the connector 31 and extends from the rope groove outlet 33.

[0029] The operation process of this horseshoe-shaped cross-section multi-mode through-type lining trolley device is as follows: Figure 5 As shown:

[0030] 1. After completing the pouring operation of N compartment and waiting for the concrete to initially set for about 4 hours, disconnect the various hydraulic cylinders of trolley 1 from the N compartment formwork, leaving the N compartment formwork in the N compartment.

[0031] 2. Move trolley 1 to the already poured N-1 compartment, connect the various hydraulic cylinders of trolley 1 to the N-1 compartment template, and demold;

[0032] 3. The trolley 1 with the template moves through the template of warehouse N to the position of warehouse N+1;

[0033] 4. After the templates are installed in place, connect the N-cell templates and the N+1-cell templates through the second connection structure and then pour the concrete.

[0034] 5. After the concrete has set for 4 hours, repeat the above steps to proceed with the N+2 section pouring process.

[0035] Working principle of the first connecting structure in this horseshoe-shaped cross-section multi-mode through-type lining trolley device:

[0036] When it is necessary to disconnect the template and the hydraulic cylinder, first remove the pin, then the electric rope retractor releases the pull rope 4 by a certain length, then the hydraulic cylinder retracts to make the plug part 31 disengage from the plug groove 21. After the person is away from the trolley device, the electric rope retractor slowly releases the pull rope 4 to make the hydraulic cylinder fall down. Finally, remove the pin and take the first connecting column 2 off the template.

[0037] When it is necessary to connect the template and the hydraulic cylinder, first install the first connecting post 2, then tighten the pull rope 4 by the electric rope retractor so that the first connecting post 2 and the second connecting post 3 are axially aligned, and then the hydraulic cylinder extends so that the insertion part 31 is inserted into the insertion groove 21 and fixed by the pin.

[0038] This device can solve the problem of crossing between templates, realize multi-template construction schemes, reduce the waiting time for demolding after the initial setting of concrete, thereby achieving continuous operation and improving construction efficiency. More importantly, it can solve the problem of difficult disassembly and assembly of the template and the hydraulic cylinder, especially the problem of the heavy hydraulic cylinder falling when disconnected from the template. When the horseshoe-shaped cross-section multi-template through-type lining trolley device removes the pin, since the insertion part 31 is still located in the insertion groove 21, even if the pull rope 4 loses tension, the hydraulic cylinder can be supported by the first connecting column 2 and will not suddenly fall, greatly improving safety.

[0039] As an optional embodiment of the present invention, the second connection structure includes bolts, and two adjacent sets of the templates are locked together by bolts.

[0040] As an optional embodiment of the present invention, the pull rope 4 is connected to the electric rope retractor via an elastic rope 5. When connecting the first connecting post 2 and the second connecting post 3, the elastic rope 5 always remains in a pulled state, thereby ensuring that when the second connecting post 3 moves relative to the pull rope 4, the pull rope 4 is always taut, thus making the first connecting post 2 and the second connecting post 3 axially aligned.

[0041] As an optional embodiment of the present invention, in order to accommodate small amplitude vibrations and errors, the end of the plug-in portion 31 is provided with a chamfer 311, which makes it easier for the end of the plug-in portion 31 to be inserted into the plug-in groove 21.

[0042] As an optional embodiment of the present invention, a guide block 6 is provided in the insertion slot 21. The connection point between the pull rope 4 and the first connecting post 2 is located on the side of the guide block 6 away from the insertion part 31. A second rope groove 61 is provided on the guide block 6 along the axial direction of the first connecting post 2. The second rope groove 61 and the first rope groove 32 are coaxially arranged. The pull rope 4 passes through the second rope groove 61. The main purpose of the guide block 6 and the second rope groove 61 is to make the axis of the first connecting post 2 coincide with the axis of the pull rope 4 under the guidance of the guide block 6 when the pull rope 4 is taut, thereby facilitating the connection between the first connecting post 2 and the second connecting post 3.

[0043] As an optional embodiment of the present invention, each set of templates includes a top mold 7, two side molds 8, and two bottom molds 9. The top mold 7 has side molds 8 and bottom molds 9 on both sides. The top mold 7 is connected to the trolley 1 via a top mold cylinder 10. The side molds 8 are connected to the trolley 1 via side mold cylinders 11. The bottom molds 9 are connected to the trolley 1 via bottom mold cylinders 12. The side molds 8 are connected to the top mold 2 via hinges. The system also includes a third connecting structure for detachably connecting the side molds 8 and the bottom molds 9. After the third connecting structure connects the side molds 8 and the bottom molds 9, the modules are fixed together as a whole, and the structure is stable. In this embodiment, the third connecting structure is a bolt.

[0044] As an optional embodiment of the present invention, it also includes support rods 13 for connecting the trolley 1 and the template. The support rods 13 are metal rods with supporting capacity. There are at least five support rods 13, which are respectively connected to the top mold 7, the side mold 8 and the bottom mold 9. The support rods 13 are at least detachably connected to the template. The main purpose of the support rods 13 is to ensure the stability of the structure and shape of the template during casting.

[0045] As an optional embodiment of the present invention, the bottom of the trolley 1 is provided with a lifting cylinder 14, the output shaft of the lifting cylinder 14 is set downwards, and during the pouring, the lifting cylinder 14 is lowered so that its output shaft touches the ground, thereby so that the tires do not bear the load during the pouring operation.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
