Description

TECHNICAL FIELD

[0001] The utility model relates to shield segment prefabricated component processing technical field especially based on shield segment prefabricated component mould's release agent spraying device. BACKGROUND

[0002] The shield segment prefabricated component mould is a special tool for making shield segments. The shield segment mould forms the segments with specific size, shape and specification by moulding, to meet the needs of tunnel construction. These segments are important components of shield construction, which are used to form the inner wall of shield tunnel and support the tunnel.

[0003] The mould release agent spraying device is designed for spraying release agent on the mould. It can efficiently and uniformly spray the release agent on the mould surface, thus improving the release efficiency and quality. During the operation of the automatic spraying device, the release agent raw material barrel sends the release agent to the spraying head through the feeding pipe; the air compressor sends compressed gas to the spraying head, which mixes with the release agent to form misty spraying material. The spraying head uniformly sprays the misty spraying material on the mould surface through the nozzle.

[0004] In the prior art, the spraying head sprays the release agent on the mould surface through the nozzle. However, during the spraying process, some misty release agent condenses around the nozzle of the spraying head. These misty release agent cannot be effectively sprayed on the mould surface, and after fully condensing, it will also drip on the sprayed mould surface, which will further affect the uniformity of the spraying device on the mould surface. SUMMARY

[0005] The utility model discloses a release agent spraying device based on a shield segment prefabricated component mould. The release agent can be guided away through the flow guide groove, thereby avoiding the problem that the release agent will drip on the sprayed mould surface after fully condensing, which will further affect the uniformity of the spraying device on the mould surface, to solve the problems raised in the background.

The release agent conveying assembly comprises a conveying pipe penetrating through the inner wall of the top end of the spraying box body. The end of the conveying pipe located inside the spraying box body is fixedly connected with a spraying head. The outside of the spraying head is provided with a spraying condensation assembly.

[0007] The spraying agglomeration assembly is fixedly installed at the extension support at the bottom end of the spraying head, the outer side of the extension support is sleeved with the agglomeration cover, the inner wall of the agglomeration cover is provided with the flow guide grooves, and the flow guide grooves are arranged at equal angles.

[0008] Preferably, the release agent conveying assembly further comprises a release agent storage tank fixedly installed at the top end of the spraying box, a conveying pump fixedly installed at the top end of the spraying box is fixedly communicated at the front of the release agent storage tank, and the conveying pump is in communication with the spraying head and the release agent storage tank through the conveying pipe.

[0009] Preferably, the spraying box is provided with a spraying position adjusting mechanism on the inside and outside, the spraying position adjusting mechanism comprises a front-rear position adjusting assembly installed at the top end of the inside of the spraying box, and the right side of the front-rear position adjusting assembly is provided with an adjusting guide assembly installed at the top end of the inside of the spraying box.

[0010] Preferably, a left-right position adjusting assembly is arranged between the front-rear position adjusting assembly and the adjusting guide assembly, and the lower end of the left-right position adjusting assembly is connected with a spraying seat.

[0011] Preferably, an electric push rod is fixedly installed at the left side end of the spraying seat, and a plurality of high-elasticity supporting rods are fixedly connected to the output end of the electric push rod.

[0012] Preferably, the high-elasticity supporting rods are slidably connected with supporting rod limiting guide bases fixed on the outer side wall of the spraying head, and the bottom end of the high-elasticity supporting rods extends to the inside of the agglomeration cover.
