TECHNICAL FIELD
[0001] The utility model relates to tunnel engineering equipment technical field, concretely relates to a tunnel construction all -in -one with automatic telescopic guide structure. BACKGROUND
[0002] At present, in the initial support stage of tunnel construction, the installation of arch frame plays a vital role, and the folding arch frame as a kind of support structure capable of quick assembly and disassembly is widely applied in temporary building, activity site erection and tunnel construction. The design of folding arch frame usually includes the side arch part of left and right sides. However, in the current construction technology, the installation process of arch frame is quite complex, and highly depends on mechanical assistance and manual operation. The installation process is briefly described as follows: first, the folding arch frame is transported to the tail of the rack by the loader; then, the rack main arm grabs the arch frame, and the side arch is unfolded by the lifting mechanism on the left and right sides; then, the side arch grabbing mechanism cooperates with the main arm, and the unfolded arch frame is transported to the working face by the sliding assembly for installation.
[0003] However, the prior art has a significant problem: although the rack left and right sides are provided with guide sliding round pipes, these round pipes do not extend to the outside of the front and rear sides of the rack. When the folding arch frame is unfolded by the lifting mechanism, the side arch has a tendency to contract inward due to gravity. Since the guide sliding round pipes do not cover the position of the lifting mechanism at the rear end of the rack, the inward contraction of the side arch often causes the arch frame to be difficult to slide smoothly to the round pipe, thereby reducing the transfer efficiency. In addition, there is a certain distance (usually 2-3 meters) between the front end of the rack and the vertical arch area, and the guide sliding round pipe also does not extend to this area. Therefore, when the folding arch frame is transferred from the front end of the rack to the vertical arch area, the side arch naturally contracts inward due to gravity, which brings inconvenience to the subsequent vertical arch construction.
[0004] At the same time, if an extension pipe is provided at the front end of the guide sliding round pipe, in order to enable the extension pipe itself to support the side arch of the folding arch frame, the structural strength of the extension pipe itself needs to be high, which easily leads to the weight of the extension pipe being large, and the worker pulling the extension pipe is more laborious. UTILITY MODEL CONTENTS
[0005] The utility model aims at providing a tunnel construction all-in-one machine with automatic telescopic guide structure, which can support the arch frame by automatic telescopic extension piece, and is more labor-saving.
[0006] To solve the above technical problems, the utility model adopts the following scheme:
[0007] A tunnel construction all-in-one machine with automatic telescopic guide structure, comprising a rack, the side of the rack is provided with a guide and a driving device for facilitating the side arch to be dragged, the guide extends from the rear end of the rack to the front end of the rack, and an extension is arranged at the front end of the guide and can extend to the vertical arch area, and the driving device is used to drive the extension to move forward and backward. The driving device can be a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, a worm gear, a gear rack, etc. Through the design of the extension, the side arch of the arch support can be supported during the process of transferring the arch support from the front end of the rack to the working face, effectively preventing the shaking of the side arch and ensuring the smooth progress of the installation process. Through the arrangement of the driving device, the extension can be automatically driven to move forward and backward, which is labor-saving for driving the extension.
[0008] Further, the extension and the driving device are both built-in the guide, and the rear end of the extension is connected with the driving device. Through the design of the built-in driving device, damage of the driving device caused by accidental collision can be avoided.

[0016] Further, the rear end of the extension piece is provided with a hinge seat, the piston rod is connected with the hinge seat through a rotating shaft, the rotating shaft is vertically arranged with the ground, and the elastic ring is arranged at the position close to the hinge seat of the extension piece. Its role is that, since the extension piece is subjected to a large force in the horizontal direction when supporting the arch frame, the setting of the rotating shaft facilitates the horizontal deviation of the extension piece, and the service life of the extension piece and the guide piece is prolonged.
[0017] Further, the guide piece and the extension pipe are in the shape of a circular pipe or a square pipe, the guide pieces on the left and right sides of the rack are symmetrically arranged with the rack as the center, and the guide pieces are arranged in parallel with the bottom end of the rack. Its role is that, through the design that the guide pieces are symmetrically arranged on the left and right sides of the rack, the same limiting effect can be achieved on the left and right sides of the side arch; through the design that the guide pieces are arranged in parallel with the bottom end of the rack, the side arch can be kept stable during the transportation from back to front.
[0018] Further, the rear end of the guide piece is provided with an expansion pipe, and the distance between the expansion pipe and the rack gradually decreases from front to back. Its role is that, through the setting of the expansion pipe, the side arch can enter the expansion pipe when the side arch is not completely expanded, and then the side arch can be gradually expanded along the expansion pipe during the transportation from front to back.
[0019] Further, a diagonal brace is arranged between the section of the guide piece outside the front end of the rack and the front end of the rack. Its role is that, through the setting of the diagonal brace, the structural strength of the section of the guide piece outside the front end of the rack can be enhanced.

[0022] 2. By using the hinged design of the piston rod and the extension and the setting of the elastic ring, a certain deflection space can be provided between the extension and the guide when the extension supports the arch frame. This avoids direct contact between the side walls of the extension and the guide, which could easily cause deformation or damage to the extension or the guide when they are offset.
