The carriage 12 is arranged on the second guide structure, for example, by means of rotatable rollers. The second travel driving mechanism comprises a driving motor which is in transmission connection with the roller to drive the roller to rotate, so that the support 12 is displaced along the second guiding structure.
The inner die template can be switched between a closed state and an expanded state, and in the expanded state, the outer contour of the inner die template is the same as the inner contour of the inner cavity of the pipe gallery 23. As shown in fig. 9, the casting is performed in the unfolded state so that a cavity is formed inside the pipe gallery 23.
Referring to fig. 9 and 10, the inner die plate may alternatively comprise a top die plate 16, a side die plate 17 and an end die plate 18. The top template 16 is fixedly connected with the support 12, the two sides of the top template 16 are hinged with side templates 17, and the top template 16 is connected with the side templates 17 through a third linear driving mechanism 19. An end formwork 18 is hinged to one end, far away from the top formwork 16, of the side formwork 17, and the side formwork 17 is connected with the end formwork 18 through a fourth linear driving mechanism 20.
When the inner mould is in the working state, the third linear driving mechanism 19 and the fourth linear driving mechanism 20 extend to unfold the side mould plates 17 and the end mould plates 18, so that a cavity is formed inside the poured pipe gallery. Support assemblies 21 may be provided between the sideforms 17 and the support 12 and between the end forms 18 and the support 12 to increase the rigidity of the sideforms 17 and the end forms 18 and to prevent the sideforms 17 and the end forms 18 from moving. For example, the support assembly 21 may be a threaded telescoping rod.
When the inner mould is to be demoulded, all the support assemblies 21 are removed and then the third linear drive 19 and the fourth linear drive 20 are shortened to bring the sideforms 17 and the end forms 18 together to disengage the tube lane 23.
A second jacking assembly 13 is connected to the carriage 12 for driving the carriage 12 to raise and lower from and to the second guide structure. For example, the first end of the second jacking assembly is connected with the bracket, and the second end of the second jacking assembly is used for abutting against the second guide structure. The second jacking assembly may be a hydraulic telescoping structure and/or a threaded telescoping structure.

After the pouring is finished, the inner mold can be withdrawn along the second guide structure 24, and then the second guide structure 24 is withdrawn through the telescopic driving mechanism. So set up, be more convenient for send the centre form into and pour the space and withdraw from the cavity of piping lane.
The telescopic driving mechanism can be a hydraulic cylinder, a lead screw nut mechanism or a motor roller. The motor roller is a rotatable roller arranged on the second guide structure 24, the second guide structure is in sliding fit with the rack through the roller, and the motor is arranged on the second guide structure and is in transmission connection with the roller to drive the roller to rotate, so that the second guide structure is displaced along the rack.
In some embodiments provided by the present invention, the end die includes an end die plate 14 and a second linear drive mechanism 15.
For example, the end formwork template 14 is hinged to the bottom wall of the foundation pit, one end of the second linear driving mechanism 15 is hinged to the concrete wall 2, the other end of the second linear driving mechanism 15 is hinged to the end formwork template 14, and the end formwork is converted between the working state and the demoulding state through the extension and contraction of the second linear driving mechanism 15. For example, the second linear drive mechanism 15 may be a cylinder.
Further, a support assembly 21 is arranged between the end formwork 14 and the concrete wall 2 to support the end formwork 14, so that the rigidity is increased, and the end formwork 14 is prevented from moving in the pouring process. Before demolding, the support assembly 21 can be removed in advance.
Alternatively, the first guiding structure 3 comprises two parallel arranged guide rails.
