Description

Technical Field

[0001] The present invention relates to the technical field of tunnel management, and in particular to a bidirectional traveling operation device for a railway tunnel. Background Art

[0002] A tunnel is an engineering structure that can be categorized as a transportation tunnel, hydraulic tunnel, municipal tunnel, mining tunnel, or military tunnel. A tunnel's structure consists of a main structure and ancillary facilities. The main structure consists of the tunnel body and portals. Ancillary facilities include a car shelter, firefighting equipment, emergency communications, and drainage systems. Long tunnels also have specialized ventilation and lighting equipment. Tunnel construction and maintenance are carried out using tunnel construction vehicles equipped with a variety of tools, such as drills, chisels, and cutters. A chisel is a tool similar to an axe that processes the surface of a completed main structure to ensure a secure bond between the two construction stages. Chisels are commonly used in cast-in-place concrete structures. After the cast-in-place slab is poured, the surface must be chiseled to allow for the next layer to be poured and ensure a secure bond. Therefore, "chisels" are often also referred to as "concrete chisels."

[0003] In actual engineering practice, the following problems exist:

[0004] First, all the hammer heads of the existing haircutting machine work together to hammer, but there is a need in the prior art to control some of the hammer heads, for example, when hammering corners, it is suitable to use some of the hammer heads to hammer. For example, CN214293845U relates to a haircutting machine in which the working order and time of individual haircutting heads can be controlled by programming. Each air outlet channel is connected to a haircutting head through an air outlet branch pipe, but this solution requires a large number of control structures, control pipelines, and logic control chips, which is costly and has many components.

[0005] 2. The existing chiseling machine cylinders are all designed to take in air from the upper side. However, in the face of multi-channel situations, such as multi-channels controlling different cylinder movements, only taking in air from the upper side can no longer adapt to the pipeline layout with more functions.

[0006] 3. The chiseling machine cylinder in the prior art only takes into account the up and down drives, but in actual work, the downward hammering force needs to be large, and the upward return needs to be as light as possible to reduce the impact on the inner wall; the prior art has not yet realized an effective solution to this problem.

[0007] 4. In the existing technology for controlling the internal passages of the haircutting machine, only a single passage can be controlled to be on and off, but multiple passages cannot be controlled to be on and off. Some technologies can control the on and off of multiple passages, but such technologies cannot control the on and off of two passages in mutually perpendicular directions. Summary of the Invention

[0008] In order to overcome the above problems, the present invention proposes a solution to solve the above multiple problems at the same time.

[0009] The technical solution adopted by the present invention to solve its technical problems is: a two-way walking operation device for a railway tunnel, comprising a car body, a first driving cab, a second driving cab, a crawler track, a hydraulic support leg, a gantry, a platform, a support plate, a first arm, a second arm, a third arm, a fourth arm, a spray gun, a cutting device, a drilling device, a hydraulic drive mechanism, and a chiseling device, wherein the first driving cab and the second driving cab are arranged above the car body, and the first and second driving cabs face opposite directions, the crawler track is arranged below the car body, and hydraulic support legs are arranged on the side of the car body, a gantry is respectively provided at the front and rear ends of the car body, a platform is provided on one gantry, and a support plate is provided on the other gantry, the platform is provided with the first arm and the fourth arm, and the support plate is provided with the second arm and the third arm; the cutting device is provided at the working end of the first arm, the chiseling device is provided at the working end of the second arm, and the chiseling device includes a working arm and a chiseling machine, the drilling device is provided at the working end of the third arm, and the spray gun is provided at the working end of the fourth arm, and the first to fourth arms are all driven to rotate by the hydraulic drive mechanism;

[0010] The haircutting machine includes a main body, on which a driving member is installed, and a first module, a second module, an upper air inlet path, a lower air inlet path, a vertical air path, a secondary path, a main path, and a driving plate are arranged in the main body; the driving plate includes a closed portion, an opening portion, and an L-shaped portion from top to bottom; the first module includes a row of cylinder modules, and the second module includes a plurality of row of cylinder modules, and the cylinder module includes a cylinder body and a piston part; an upper chamber, a lifting chamber, a lower pressure chamber, a lower chamber, a branch air inlet path, an upper exhaust path, a lower exhaust path, an annular chamber, an upper pad, and a lower pad are arranged in the cylinder body; the piston part includes an upper piston, a connecting column, a diameter reduction rod, a lower piston, a piston rod, and a chiseling head;

[0011] The driving member can drive the driving plate to move up and down; when the closing portion closes the upper air inlet path, the upper air inlet path and the lower air inlet path are closed; when the opening portion is connected to the upper air inlet path, the lower air inlet path is closed and the upper air inlet path is connected to the secondary path; the L-shaped portion includes an L-shaped cross-section, and when the L-shaped portion is aligned with the upper air inlet path, the upper air inlet path and the secondary path are cut off, the upper air inlet path is connected to the lower air inlet path through the vertical air path, and the lower air inlet path is connected to the main path; when the L-shaped portion continues to rise from the position aligned with the upper air inlet path, the upper air inlet path is connected to the secondary path, and the lower air inlet path is connected to the main path; the main path is respectively connected to the branch air inlet path of each cylinder module in the second module, and the secondary path is respectively connected to the branch air inlet path of each cylinder module in the first module;

[0012] The lower part of the upper piston is connected to the connecting column, the lower part of the connecting column is connected to the diameter reduction rod, the lower part of the diameter reduction rod is connected to the lower piston, the lower part of the lower piston is connected to the piston rod, the lower part of the piston rod is connected to the chiseling head, and the chiseling head extends out of the cylinder body; the upper part of the upper piston is connected to the upper chamber, the lifting chamber is formed between the lower surface of the upper piston and the inner wall of the cylinder body, the lower chamber is formed below the lower piston, and the lower pressure chamber is formed between the upper surface of the lower piston and the inner wall of the cylinder body; a connecting path is provided in the connecting column; when the piston part is in the first position, the branch air inlet path outputs gas to the annular chamber and then flows to the lower pressure chamber through the outer periphery of the diameter reduction rod. During the downward pressure process, the gas in the lifting chamber is discharged through the upper exhaust path. When the piston part is in the second position, the branch air inlet path is connected to the connecting path and is connected to the lifting chamber through the connecting path. During the lifting process, the gas in the lower pressure chamber is discharged through the lower exhaust path.

[0013] Preferably, when the branch air intake path is connected to the communicating path and the fluid flows from the branch air intake path to the communicating path, the flow path area decreases.

[0014] Preferably, the number of cylinder modules in the first module is one, two, three or four.

[0021] Preferably, in working state, the bracket portion abuts against the working surface to position the haircutting machine.

[0022] The beneficial effects of the present invention are:

[0023] 1. In response to the first point raised in the background technology, an integrated chiseling machine is constructed, which realizes the switching between overall chiseling and single-row chiseling through relatively few structures, achieving two effects: overall chiseling when the working environment is ample, and single-row chiseling when the working environment is narrow or when chiseling corners. The working states include overall chiseling, single-row chiseling, chiseling of parts other than single-row, and shutdown.

[0024] 2. In response to the second point raised in the background technology, a bidirectional cylinder suitable for air intake in the middle of the haircutting machine body is proposed, so that the cylinder can be adapted to the air intake path at a low position, so that even if there are multiple functional air paths resulting in a lowered air path position, it can be reasonably adapted.

[0025] 3. In response to the third point raised in the background technology, a solution was designed with different flow paths for different upper and lower driving forces. A small flow path and a small piston were designed for upward drive, and an annular cavity, a piston rod with a reduced diameter, and a large piston were designed for downward drive to expand the air path area and increase the downward driving force.

[0026] 4. Regarding the fourth point raised in the background technology, a structure is adopted that can control the on and off of two vertical paths, which includes a closed section, an open section, and an L-shaped section. It can realize four functions of vertical bidirectional conduction, closure, lateral conduction, and folding conduction, and the structure is just a plate.

[0027] Note: The four invention points are arranged in order from the whole to the part. The order of arrangement has nothing to do with the height of the invention. All four invention points have outstanding substantive features and significant progress. BRIEF DESCRIPTION OF THE DRAWINGS
