Description

Relay pump for long-distance miniature jacking pipe

Technical Field

The utility model belongs to the technical field of long-distance micro tunnel construction equipment, and particularly relates to a relay pump for a DG100 long-distance micro jacking pipe.

Background

The slurry balance pipe jacking construction has the advantages of wide soil adaptation range, high mechanization degree, high jacking speed, controlled ground settlement and the like, and becomes a main mode of pipe jacking construction. Along with the rapid development of municipal administration, culvert and sponge city construction in recent years, the tunneling requirements of miniature (tunnel with diameter of 1200m and 300-. To this end we propose a long distance micro top tube relay pump.

SUMMERY OF THE UTILITY MODEL

The utility model provides a relay pump for a long-distance miniature top pipe, and aims to solve the problems that a sludge discharge pump is large in size and difficult to carry, and is inconvenient to repair after being worn and inconvenient to use.

The utility model is realized in such a way that the relay pump for the long-distance miniature ejector pipe comprises a sliding base, wherein a pump body, a bracket body and a motor are sequentially arranged on the upper surface of the sliding base from left to right, a bearing body assembly is fixed on the bracket body, an input shaft of the pump body penetrates through the bearing body assembly, one end, far away from the pump body, of the input shaft of the pump body is connected with an output shaft of the motor through a coupler, the right side of the pump body is fixed with the bracket body, and a fluid discharge pipeline of the pump body bends along the outer side surface of the pump body and then extends backwards.

Preferably, the bearing body subassembly includes the sleeve, establishes at the intraoral bearing in sleeve both ends, establishes the waterproof dish in the bearing outside to and establish the rings at sleeve lateral surface top again, the inner circle of bearing is again installed to the input shaft of the pump body, waterproof dish passes through the installation of impeller lock nut again on the sleeve.

Preferably, the fixed shafts on two sides of the pulley base are movably provided with rollers.

Preferably, the coupling housing has a coupling cover, and the bottom of the coupling cover is fixed to the sliding base.

Compared with the prior art, the utility model has the beneficial effects that:

1. the back-twisted pump body designed according to the fluid mechanical principle reduces the space for arranging the pump and the pipeline to the maximum extent without reducing the efficiency and the performance of the pump.

2. The adjustable pulley base is suitable for tunnels with different diameters according to the change of the tunnel curvature, is convenient to move, and can be conveniently moved in the tunnel in a narrow space without the intervention of extra personnel and equipment.

3. The design of the additional waterproof disc of the utility model ensures that slurry can not enter key parts such as the bearing and the like even if the pump is worn and leaked after being used for a period of time, the maintenance-free operation period of the whole pump is greatly prolonged, and the maintenance frequency is greatly reduced. The method has good effect in the pipeline construction of medium petroleum.
