Description

Technical Field

[0001] The utility model relates to the technical field of shield machine water jet orientation, in particular to a shield shell externally attached water jet orientation device. Background Art

[0002] At present, when the soil under the shield is removed, the cutting distance is long, the water jet gun rod is more elastic and has a larger deadweight after being lengthened. During the soil cutting process, the operating space is small, the water jet gun rod is more elastic and has a larger deadweight, which makes it easy for the cutting range to be uncontrollable and the shield machine posture adjustment effect to be poor.

[0003] Therefore, the posture of the shield machine is uncontrollable, which will lead to large deviations from the designed route and cause great losses. Summary of the invention

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A shield shell externally attached water jet orientation device comprises a body, the top of the body is provided with a fixing component for fixing the water jet; the bottom of the body is provided with an adsorption component outside the shield shell for adsorption;

[0006] Wherein, the adsorption component is a magnet, and the magnet is fixed at the bottom of the body; the fixing component is two arc-shaped fixing parts arranged oppositely at the two ends of the body.

[0007] Furthermore, a groove is provided on the top of the body, and a through hole is provided in the groove.

[0008] Furthermore, the main body is a rectangular parallelepiped structure, the groove is a rectangular parallelepiped groove, and the through hole is a strip hole composed of a rectangle and two semicircles.

[0009] Furthermore, the center of the groove, the center of the through hole and the center of the body are concentric.

[0010] Furthermore, the magnets are two circular magnets, which are arranged oppositely at two ends of the body.

[0011] Furthermore, the circular magnet at least partially overlaps with a portion of the through hole.

[0012] Furthermore, the body is provided with wheels. Beneficial Effects

[0013] (1) The device has a simple structure, is easy to install and has low installation difficulty.

[0014] (2) The device is easy to manufacture and has low cost.

[0015] (3) The device is easy to use and improves safety. During use, it only needs to be attached to the outside of the shield shell and moved back and forth with the gun rod to maintain a certain safe distance from the workers.

[0016] (4) This device can control the soil cutting range in a narrow working space by being adsorbed on the lower part of the shield shell, thus solving the problem of high elasticity of the water jet gun rod and uncontrollable cutting range during the process of adjusting the posture of the water jet cutting shield machine soil.
