The following is an assembly principle of an assembly type lining trolley capable of realizing rapid turnover:
the trolley can quickly assemble and disassemble between adjacent sections. The assembly principle is divided into two stages: the first stage is the fabricated installation of the heightened portal. The heightening portal frame is assembled on the ground and is overlapped on the basic portal frame through hoisting, and the assembly of the portal frame assembly is completed. The second stage is the assembly installation of the top die plate assembly. The top template assembly is synchronously assembled on the ground, and then is overlapped on the portal assembly through hoisting to complete the second assembly. The method comprises the following steps of carrying out hoisting operation by adopting a digging machine or a mode of arranging pre-buried hoisting points on the top of a tunnel, splitting a top template assembly into a plurality of top template assembly monomers according to hoisting capacity, and completing simple assembly after the top template assembly is hoisted to a portal assembly in a subsection mode.
The trolley can finish rapid transfer between non-adjacent sections, and greatly saves the time that the trolley needs to be disassembled first and then transferred to the next section for re-assembly. The disassembly process of the trolley is opposite to the assembly process, the top template assembly is hoisted and unloaded to the ground, and the whole trolley is transported to the next section to wait for hoisting again. And unloading the heightening portal assembly to the ground by using the same operation, and integrally transferring to the next section to wait for hoisting again. Whether the top template assembly needs to be widened or not is judged according to the size condition of the next section, the side template assembly is heightened, local spare and accessory part replacement or reinforcement is carried out on the heightened portal assembly, a mechanical screw rod is adjusted, and the like.
The turnover principle of the assembled lining trolley capable of realizing quick turnover is as follows:
if the cavern A and the cavern C are non-adjacent caverns of the underground engineering, the cavern A and the cavern C have similar or same section sizes, and the application range of the trolley is met. The two chambers are connected by a main channel B, the spatial relationship of which is shown in fig. 4. After the trolley is used for lining the cavern A, the trolley needs to be quickly transferred to the cavern C for lining construction.
a. If cavern A is the same with cavern C's section size, and cavern B's space is enough again to let the platform truck transport under the condition that does not carry out the dismouting, and that only needs to accomplish according to 3 steps and transports:
step 1: and evacuating the trolley in the chamber A to the chamber B along the track.
Step 2: temporary supporting structures such as pier columns and the like are respectively placed on the bottom surfaces of two ends of each trolley lower longitudinal beam, a trolley hydraulic system is started, so that the hydraulic oil cylinder contracts to drive the transverse moving mechanism and the traveling system to be separated from the track, and the weight of the trolley is born by the temporary supporting structures. And (3) removing a matched bolt in the transverse moving mechanism, rotating the lower turntable and a traveling system connected with the lower turntable by 90 degrees under the assistance of a bearing in the transverse moving mechanism, and fixing the transverse moving mechanism by using the matched bolt. And drawing out the track, moving the track into the chamber B for placing again so as to put the head-on walking wheels down again. And starting the hydraulic system of the trolley again, so that the hydraulic oil cylinder stretches and retracts to drive the transverse moving mechanism and the traveling system to be separated from the contact with the steel rail again, drawing away the temporary supporting mechanism, and applying the weight of the trolley to the rail again through the hydraulic system and the traveling system. And starting the trolley traveling system to allow the trolley to travel to the outlet of the cavern C. The purpose of this step is to allow the wheels of the trolley to rotate 90 degrees in the cavern B while maintaining the orientation of the superstructure of the trolley, and then continue to travel to the intersection with the cavern C.
And step 3: and (3) the trolley is moved to the cavern C only by repeating the operation in the step (2), the walking wheels are rotated by 90 degrees again to restore the walking wheels to the original positions, and the cavern C is pushed to start lining construction.
b. If the cross section sizes of the chamber A and the chamber C are similar, or the space of the chamber B is not enough for the trolley to transfer without disassembly and assembly, the trolley top template assembly, the side template assembly or the heightening portal assembly are unloaded and transferred to the position near the lifting point of the chamber C, and necessary preparation works such as heightening portal adjustment or heightening the top template and the side template are completed. And then, moving the basic portal assembly to the position near the hoisting point of the chamber C by using the operation of the step 1-3, and completing the assembly type assembly of the trolley in the chamber C.
The above is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that several variations and modifications can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
