Description

Technical Field

[0001] The utility model relates to the technical field of wet spraying manipulators, in particular to an air inlet pipeline for a concrete wet spraying trolley. Background Art

[0002] In the process of tunnel excavation by drilling and blasting, wet spraying robots are usually used for concrete spraying operations, and accelerators must be mixed in the concrete before spraying to ensure construction quality. During the concrete spraying process, high-pressure air is required for pressurization to achieve the purpose of mixing concrete and accelerators and high-speed concrete spraying. During the operation, the nozzle may become clogged, and the staff will need to remove the nozzle for processing. During the removal of the nozzle, the pressure in the pipe will be released, which can easily cause injury to the operator.

[0003] Existing air supply pipelines for wet concrete spraying vehicles, such as the air supply pipeline for wet concrete spraying vehicles disclosed in Publication (Announcement) No.: CN217318559U, install an air control ball valve and a high-pressure air supply pipe together. When installing the high-pressure air supply pipe, a position for the air control ball valve needs to be reserved, which takes up a large space during installation. Every time the air pressure in the pipe is checked, it is necessary to check the air pressure in the pipe at the high-pressure air supply pipe. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses an air inlet pipe for a concrete wet spraying trolley. The utility model saves the space occupied by the equipment and does not require too much space to be reserved at the installation position of the air inlet pipe. At the same time, the pressure can be relieved in advance when the nozzle is disassembled to avoid damage to the operator, making it convenient for the operator to operate.

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with Figure 1 The air inlet pipeline for a concrete wet spraying trolley comprises an air inlet pipe 1, and ball valves are respectively installed at both ends of the air inlet pipe 1, the exhaust port of the air inlet pipe 1 is connected to one end of an air duct 2, and the other end of the air duct 2 is connected to one end of an electric ball valve 3, the air outlet of the electric ball valve 3 is connected to an air outlet pipe 4, and the electric ball valve 3 has a remote operation function.

[0018] The air duct 2 is made of a hose material, and the air intake pipe 1 and the electric ball valve 3 can be installed at different positions, without having to reserve too much space at the installation position of the air intake pipe 1.

[0019] A pressure relief ball valve 6 is installed on one end of the electric ball valve 3 connected to the air duct 2. The air pressure in the air duct 2 is released through the pressure relief ball valve 6, and the pressure relief ball valve 6 also has a remote operation function.

[0020] A pressure gauge is installed on one end of the electric ball valve 3 connected to the air duct 2, so that the staff can check the air pressure in the pipe at any time.

[0021] A support frame 5 is installed on one end of the electric ball valve 3 connected to the air outlet pipe 4.

[0022] The support frame 5 is a T-shaped plate, and bolt holes are respectively provided on the four corners of the horizontal plate of the support frame 5.

The electric ball valve 3 is used to control the supply and stop of high-pressure air. When the nozzle needs to be removed, the air pressure in the pipe is discharged through the pressure relief ball valve 6 to avoid the high pressure in the pipe from hurting the staff when the nozzle is removed.
