Abstract

The utility model provides a mud mixing station suitable for a trenchless drilling machine providing hydraulic power. The mud mixing station comprises a mud mixing station body; the mud mixing station body comprises a Venturi hopper, a mud tank, a horizontal centrifugal mud pump and a motor, which are correspondingly communicated through pipelines. The mud mixing station is characterized in that the motor is a hydraulic motor driven by pressure oil in the trenchless drilling machine; an output shaft of the hydraulic motor driven by the pressure oil in the trenchless drilling machine is connected and fixed with an impeller of the horizontal centrifugal mud pump. The mud mixing station is suitable for trenchless drilling machines.

Description

A kind of mud mixture station that hydraulic power is provided by non-digging drill

Technical field

The utility model relates to a kind of mud mixture station, particularly relates to a kind of mud mixture station that hydraulic power is provided by non-digging drill.

Background technology

Non-digging drill creeps into as reducing drill bit resistance at underground, cooling or lubricated drilling bucket and drilling tool, must use mud, and be transported in hollow drilling rod by grouting pump, again by equally distributed mud small hole injection on drill bit to the face of creeping into, mud pressure is more than 10 MPas, the use of mud is not only in order to creep into, also can play pressure balance effect to boring, make duct be difficult for caving in, on the heavy stratum of the sand content of features as poor geologic condition, mud also needs to add other materials and keeps pore-forming, holds hole wall and carries out smoothly to guarantee construction.

Existing slush pump power has all adopted small size gasoline, Diesel engine or motor, and aluminium alloys four-cycle, single-cylinder put-put use at most.

For pipeline, install and construction requirement, between slush pump and hopper, space length is little, therefore drives the petrol engine of slush pump just by hopper.In mud conditioning process, early stage, mud allotment was generally that mud materials is added to water mixture, the main composition of mud materials is swell soil, its granularity is very thin, more than 200 orders, while preparing mud in hopper, with a dead lift to batch turning in hopper, make the thin dirt of kicking up be easy to be inhaled in the air filter of put-put, after Filtering Efficiency of Air Filters is poor, can not play barrier effect completely just enters in put-put cylinder body and causes the parts such as gasoline engine cylinder piston to wear and tear in advance, and cause that fault produces, and put-put cylinder piston is all that aluminum alloy materials is made and wears no resistance than ironcasting, this is also the unavoidable weakness of put-put maximum, general life cycle only one year left and right just substantially scrapped.

In addition, motor needs 380V power supply, but construction does not have fixing power supply in the wild, and though vapour, Diesel engine are without power supply, but the shortcoming yet existing is mainly complex structure, if any cylinder body, piston, connecting rod, bent axle, spark plug, the parts such as inlet and outlet door, and easily cause and damage and maintenance trouble.

Generally speaking, existing slush pump provides power also to have problems by motor or small size gasoline, Diesel engine, therefore needs further perfect.

Summary of the invention

The purpose of this utility model is that a kind of improved mud mixture station that hydraulic power is provided by non-digging drill will be provided, it not only can be effectively for digging drill provides required mud, but also the hydraulic motor that both can guarantee mud mixture station continues normally to work all the time, can make again hydraulic motor and the non-digging drill at mud mixture station share hydraulic system power, thereby reduce use cost.

Solution of the present utility model is to achieve the above object: of the present utility modelly a kind ofly by non-digging drill, provide the mud mixture station of hydraulic power to comprise mud mixture station, described mud mixture station is formed by venturi hopper, mud tank, horizontal centrifugal slush pump and motor, and do corresponding connection by pipeline, described motor is the hydraulic motor being driven by the pressure oil of non-digging drill, the output shaft of the described hydraulic motor driving for the pressure oil by non-digging drill and form and be connected and fixed with the impeller of described horizontal centrifugal slush pump.

The utility model has improved existing mud mixture station, and the motor at mud mixture station is adopted to the hydraulic motor being driven by the pressure oil of non-digging drill, the hydraulic motor being driven by the pressure oil of non-digging drill is connected by three hydraulic oil pipes with the hydraulic system on non-digging drill, it is one-in-and-one-out hydraulic oil pipe, the hydraulic motor drain mast that also has the pressure oil by non-digging drill to drive, from convenience, consider to select and insert type snap joint connection, hydraulic oil pipe has been connected to form hermetic hydraulic system.

The utility model is selected high-speed hydraulic motor, is connected to rear its power and the hydraulic system of sharing on working non-digging drill, and after main frame leaves, the hydraulic motor being driven by the pressure oil of non-digging drill rotarily drives horizontal centrifugal slush pump and just can work.

Non-digging drill needs high-power Diesel engine to drive hydraulic pump on rig to produce hydraulic power, the power of high-power Diesel engine of non-digging drill own is 150 kilowatts of left and right, for the work of creeping into of non-digging drill provides powerful power, mud is allocated to required excess power demand (approximately 5 kilowatts) can be taken into account when the technical design, can not cause under powered burden.

Debugging by sample of the present utility model is used, can reach the effect that building site is used completely, can complete venturi hopper feeding quantity, also meet the requirement of mud system internal circulating load, compared with original slush pump because Torque Performance of Hydraulic Motor is large, so situation performance thicker and relatively thickness is more outstanding to mud, and also have steadily, stepless speed regulation, the advantages such as noise is low, share hydraulic system power with non-digging drill, can reduce actual Energy in use and meet low-carbon (LC), the environmental protection requirements of the times of energy-saving and emission-reduction, also reduce customer using cost simultaneously, for user, bring the convenience of the aspects such as maintenance.Also do not exist non-digging drill and horizontal centrifugal slush pump to interfere with each other, mutually pin down situation, because mud mixture station is complementary equipment, it is to coordinate non-digging drill work, and rig leaves, the work of horizontal centrifugal slush pump, and rig stops, and it has also stopped.

The high-power Diesel engine of non-digging drill is allocated place away from mud, and swell soil smalls can not exert an influence to it, adopts the work of fluid motor-driven horizontal centrifugal slush pump also there is no these problems completely.

Of the present utility modelly a kind ofly by non-digging drill, provide the mud mixture station of hydraulic power to be suitable for non-digging drill to apply.
