Abstract

The utility model relates to a hydraulic power head drilling machine, and comprises a pumping station (6), an operation desk (5), a stander (4), an upright post framework (1), a power head (3) and a drilling tool (2). The power head (3) adopts a structure of an overall flange principal axis which is simple, reliable, and hard to wear and need not replace the principal axis frequently. The upright post in the upright post framework (1) adopts a structure of a screw jack, and is simple, reliable and low in cost. The drilling machine is applicable to drilling engineering holes of various kinds on the ground or in a mine tunnel.

Description

The hydraulic power head churn

Technical field

The utility model relates to a kind of hydraulic power head churn, the hydraulic power head churn that particularly uses in the tunnel.

Background technology

Existing similar hydraulic power head churn is made up of pumping plant, operating desk, frame, column frame, unit head, drilling tool etc.Unit head adopts six square shafts and six side's nested structures, and six square shafts are enclosed within the six sides cover, and the torque of transmitting motor with six square shafts is to water swivel axis, but six square shaft nested structure more complicated, difficulty of processing is big, cost is high, and the seamed edge of six square shafts is easy to wear and can't transfer torque in the use, must often change; In addition, column in the column frame adopts the hydraulic prop structure, makes, maintenance cost is higher, and dependability is poor.

Summary of the invention

The purpose of this utility model is a kind of hydraulic power head churn of design, and its unit head transmits the simple and reliable for structure, easy for operation of torque.

The technical solution of the utility model is: the main shaft of unit head in housing respectively by about two bearings; Pack into the Kong Zhongyu main shaft of main shaft input end of motor output shaft is fixedly connected; The output of main shaft adopts the flange disc structure to fixedly connected with water swivel axis; Ring washer, snap ring, shelves ring set are in the input of main shaft, the left side of left bearing, to the input axial location of main shaft; Oil seal washer, gland, collar, floor clip, locking nut are enclosed within the output of main shaft, the right side of right bearing, and the main shaft output is located; The shell of motor and gland are separately fixed at the two ends, the left and right sides of housing.

The outer steel pipe socket of column frame central post is outside interior steel pipe, and the lower end of interior steel pipe is welded with lining, and rotating nut is fixedlyed connected with lining, and screw mandrel top screws in rotating nut and the lining, and the bottom is fixed on the base.

After adopting this structure, main shaft is not easy to wear, need not often overhaul replacing, has improved rig operating efficiency and reliability; Column in the column frame adopts the jackscrew structure, and the rotation rotating nut just can change the anchored force of the column in the rig column frame, has improved reliability, has reduced cost.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

The specific embodiment

Fig. 1 embodiment the utility model rig is made up of pumping plant 6, operating desk 5, frame 4, column frame 1, unit head 3, drilling tool 2 etc.

The main shaft 10 of the unit head 3 of Fig. 2 embodiment the utility model rig in housing 9 respectively by about two bearings 11,17 support; Pack into the Kong Zhongyu main shaft 10 usefulness keys of main shaft 10 inputs of motor 7 output shafts connect; The output of main shaft 10 adopts the flange disc structure to fixedly connected with water swivel axis 14; Ring washer 15, snap ring 8, shelves ring 16 are enclosed within the input of main shaft 10, the left side of left bearing 11, to the input axial location of main shaft 10; Oil seal washer 13, gland 12, collar 18, floor clip 19, locking nut 20 are enclosed within the output of main shaft 10, the right side of right bearing 17, and main shaft 10 outputs are located; The shell of motor 7 and gland 12 are separately fixed at the two ends, the left and right sides of housing 9.The pressure oil of pumping plant 6 outputs to unit head motor 7, makes motor 7 produce gyration through operating desk 5, output shaft drive shaft 10 revolutions of motor 7, and main shaft 10 is passed to water swivel axis 14 with rotary motive power, and water swivel axis 14 drives drilling tool 2 revolutions.

The column of Fig. 3 embodiment the utility model rig comprises outer steel pipe 21, latch 22, interior steel pipe 23, lining 25, rotating nut 26, alignment pin 24, screw mandrel 27, pin 28, base 29 etc., outer steel pipe 21 is enclosed within outside the interior steel pipe 23, the lower end of interior steel pipe 23 is welded with lining 25, rotating nut 26 usefulness alignment pins 24 are fixedlyed connected with lining 25, screw mandrel 27 tops screw in rotating nut 26 and the lining 25, and the bottom is connected with base 29 with pin.Interior steel pipe 23 stretches in the steel pipe 21 outside, in the hole on steel pipe 23 and the outer steel pipe 21 in latch 22 insertions, steel pipe 23 outer steel pipes 21 in fixing manually rotate rotating nut 26 and can make outer steel pipe 21 rise or descend, to change the anchored force of the column in the column frame.This column work is simple and reliable, cost is low, and is easy to maintenance.
