Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel management, in particular to a chiseling machine. BACKGROUND

[0002] A tunnel is an engineering structure, which can be divided into traffic tunnels, water tunnels, municipal tunnels, mine tunnels and military tunnels. The structure of a tunnel includes a main building and auxiliary equipment. The main building is composed of a tunnel body and a tunnel portal, and the auxiliary equipment includes a vehicle escape hole, fire-fighting facilities, emergency communication and drainage facilities, and long tunnels have special ventilation and lighting equipment. Tunnel construction and maintenance are realized by a tunnel construction vehicle, which is loaded with various tools such as a drilling machine, a chiseling machine and a cutting machine. The chiseling machine is a tool similar to an axe that processes the completed main structure surface to make the construction surfaces of two construction stages firmly bonded. Generally, the chiseling machine is applied in cast-in-place concrete structures. After the cast-in-place slab is poured, chiseling is performed for the pouring of the next layer to make the concrete firmly bonded. Therefore, the chiseling machine is also commonly referred to as a "concrete chiseling machine".

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

[0004] 1. All hammer heads of the existing chiseling machine perform hammering together, but there is a need to control some hammer heads, for example, when hammering the corner position, some hammer heads are suitable for hammering. For example, CN214293845U relates to a chiseling machine capable of controlling the working sequence and time of a single chiseling head through programming. Each air outlet passage is connected to a chiseling head through an air outlet branch pipe, but this scheme requires a large number of control structures, control pipelines and logic control chips, which is high in cost and has many components.

[0005] 2. The air cylinder of the existing chiseling machine is designed to intake air from the upper side, but in the case of multiple passages, such as controlling different air cylinder movements, only air intake from the upper side cannot adapt to the layout of more functional pipelines.

[0006] 3. The air cylinder of the existing chiseling machine only considers up-down driving, 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 existing technology has not realized a scheme to effectively solve this problem.

[0007] 4. In the internal passage control of the existing chiseling machine, only the on-off of a single passage can be controlled, and the on-off of multiple passages cannot be controlled. Some technologies can control the on-off of multiple passages, but such technologies cannot control the on-off of two passages in perpendicular directions. SUMMARY

[0008] To overcome the above problems, the present application proposes a solution to simultaneously solve the above problems.

[0009] The technical scheme adopted by the present application to solve its technical problems is: a gouging machine, comprising a main body, a driving member mounted on the main body, 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 arranged in the main body; the driving plate comprises a closed portion, an open portion, and an L-shaped portion from top to bottom; the first module comprises a row of cylinder modules, and the second module comprises a plurality of cylinder modules; the cylinder module comprises a cylinder body and a piston portion; the cylinder body is provided with an upper cavity, a lifting cavity, a pressing-down cavity, a lower cavity, a branch air inlet path, an upper exhaust path, a lower exhaust path, an annular cavity, an upper pad, and a lower pad; the piston portion comprises an upper piston, a connecting column, a diameter-reducing rod, a lower piston, a piston rod, and a gouging head;

[0010] The driving member can drive the driving plate to move up and down; when the closed portion closes the upper air inlet path, the upper air inlet path and the lower air inlet path are closed; when the open portion communicates the upper air inlet path, the lower air inlet path is closed, and the upper air inlet path communicates with the secondary path; the L-shaped portion comprises an L-shaped cross section; when the L-shaped portion is aligned with the upper air inlet path, the upper air inlet path is cut off from the secondary path, the upper air inlet path communicates with the lower air inlet path through the vertical air path, and the lower air inlet path communicates with the main path; when the L-shaped portion continues to lift from the position aligned with the upper air inlet path, the upper air inlet path communicates with the secondary path, and the lower air inlet path communicates with the main path; the main path respectively communicates with the branch air inlet path of each cylinder module in the second module, and the secondary path respectively communicates with the branch air inlet path of each cylinder module in the first module;

[0011] The connecting column is connected below the upper piston, the diameter-reducing rod is connected below the connecting column, the lower piston is connected below the diameter-reducing rod, the piston rod is connected below the lower piston, the gouging head is connected below the piston rod, and the gouging head extends out of the cylinder body; the upper cavity is above the upper piston, the lifting cavity is formed between the lower surface of the upper piston and the inner wall of the cylinder body, the lower cavity is below the lower piston, and the pressing-down cavity is formed between the upper surface of the lower piston and the inner wall of the cylinder body; the connecting column is provided with a communication path; when the piston portion is at a first position, the branch air inlet path outputs gas to the annular cavity, and then the gas flows to the pressing-down cavity through the outer periphery of the diameter-reducing rod; during the pressing-down process, the gas in the lifting cavity is discharged through the upper exhaust path; when the piston portion is at a second position, the branch air inlet path communicates with the communication path, and the branch air inlet path communicates with the lifting cavity through the communication path; during the lifting process, the gas in the pressing-down cavity is discharged through the lower exhaust path.

[0012] Preferably, when the branch air inlet path communicates with the communication path, and fluid flows from the branch air inlet path to the communication path, the flow area decreases.

[0013] Preferably, the number of cylinder modules in the first module is one, two, three, or four.

[0014] Preferably, the number of each row of cylinder modules in the second module is the same as the number of cylinder modules in the first module.

[0015] Preferably, a lower pad is arranged in the lower pressing cavity, and an upper pad is arranged in the lifting cavity.

[0016] Preferably, the diameter of the lower piston is larger than the diameter of the upper piston.

The first point raised in the background art is to construct an integrated chiseling machine, which realizes the switching of overall chiseling and single-row chiseling through fewer structures, realizes the two effects of overall chiseling when the working environment is spacious and single-row chiseling when the working environment is narrow or chiseling corners, and the working states include overall chiseling, single-row chiseling, other partial chiseling except single-row chiseling, and shutdown.

[0023] II. The second point raised in the background art is to propose a bidirectional cylinder adapted to the middle air inlet of the chiseling machine main body, so that the cylinder can be adapted to the low-position air inlet, so that even if there are multiple functional air paths, the air path position can be reasonably adapted.

[0024] III. The third point raised in the background art is to design a scheme of different flow paths for different driving forces upward and downward, wherein a small flow path and a small piston are designed for upward driving, and an annular cavity, a reduced-section piston rod, and a large piston are designed for downward driving to expand the air path area and improve the downward driving force.

[0026] Note: The four invention points are arranged in the order from the whole to the local, and the arrangement order is irrelevant to the invention height. The four invention points all have outstanding substantial features and significant progress. BRIEF DESCRIPTION OF DRAWINGS
