Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, in particular to a grouting pipe propeller. Background Art

[0002] Grouting, in construction engineering, refers to the method of injecting certain curable slurries into cracks or pores in rock foundations by appropriate methods, in order to improve their physical and mechanical properties through replacement, filling and extrusion.

[0003] At present, in the process of building grouting, corresponding propellers are configured on the grouting pipes. The propellers are devices that convert any form of energy into mechanical energy, and the propellers mainly generate thrust by rotating blades or jets to better guide the slurry into the interior of the grouting pipe.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. Existing thrusters, during use, will cause noise and vibration due to gear meshing connection, oil leakage and water ingress due to seal failure, resistance and loss due to shaft system, and turbulence and weight increase due to attachments;

[0006] 2. During use, the existing thrusters are locked and connected to the device by multiple bolts, so that when the staff disassembles and repairs the existing thrusters, they need to remove the entire existing thrusters from the device, which not only makes the operation steps cumbersome, but also increases the workload of the staff.

[0007] To this end, we provide a grouting pipe thruster to solve the above-mentioned problems. Utility Model Content

[0008] The utility model aims to provide a grouting pipe thruster, which solves the problems of resistance, noise, energy loss, large weight and large disassembly and assembly workload of the existing thrusters by arranging a thruster body and a connecting assembly.

[0012] The utility model is further configured that an internal thread groove is provided on the side wall of the forward shell, and an external thread ring fixedly connected to the side wall of the reverse shell is threadedly connected to the internal thread groove.

[0013] The utility model is further configured such that the free end of the cable connected to the rim-type motor passes through the forward housing, and the internal length dimensions of the forward housing and the reverse housing are both half of the rim-type motor.

[0014] The utility model is further configured such that the reverse screw cover has a T-shaped appearance, the forward screw cover has a cylindrical appearance, and the cross-sections of the reverse screw cover and the forward screw cover are both T-shaped.

[0015] The utility model is further configured that a flange is connected to the side wall of the forward screw cover, and a flange is connected to the side wall of the reverse screw cover, and the flange is T-shaped in shape.
