Abstract

The utility model belongs to the field of drilling equipment, and in particular relates to a hydraulically driven power head of a deep hole hydraulic core drilling machine for deep hole coring construction. The power head is driven by four hydraulic motors, and consists of a box body, a main shaft and a power head bracket, wherein the main shaft is provided with a fixed gear, a big through hole is formed in the middle of the main shaft, and the power head bracket is used for assisting in lifting the power head and provided with a rhombic rack; and the rhombic rack is connected with a pair of hydraulic oil cylinder through a triangular support, and the power head bracket is connected with a guide rail at the same time. The drift diameter of the main shaft of the power head is large, and the power head is compact in structure; the power head transmits high output power by drive of the four hydraulic motors, provides a large rotary torque, and has the advantages of light weight, small size, stepless speed regulation and overload protection; by using the hydraulic oil cylinders, the speed of lifting and lowering a drilling tool can be easily controlled, pressure at the bottom of a hole is easily controlled, and coring exploration construction is realized; and lifting forces provided by the hydraulic oil cylinders are symmetrically distributed, so that the guide rail does not produce bending moment, the power head can bear a huge lifting force, and large-load deep hole construction is finally realized.

Description

Deep hole all-hydraulic core drill unit head
Technical field
The utility model belongs to the drilling equipment field, is specifically related to a kind of hydraulically powered deep hole all-hydraulic core drill unit head.
Background technology
Rock-core borer is a kind of machinery that is used for solid mineral deposit exploration collect specimen, and all-hydraulic core drilling rig is widely used in geological prospecting because of it is light, efficient, the rate Gao Erzheng of coring progressively replaces the mechanical type rock-core borer.Along with fast development of national economy, to the corresponding raising that requires of resource, the deep layer exploration looks for the ore deposit to become the object of mainly assaulting fortified position of China's geological work.In recent years, solid mineral deposit exploration requires increasingly highly to drilling equipment, and the development of all-hydraulic drilling equipment is maked rapid progress.
The vertical shaft rotary drill of tradition rock core exploration usefulness is widely used a kind of main type, the drilling operation requirement in incompatible modern times at present both at home and abroad.This type is the machine driving gear shift of multi-stage gear, low or first gear, and moment of torsion is little, is difficult to carry out the construction of macropore high pulling torque; The top gear rotating speed is high, it is big to impact, and is very high to the requirement of gear, and whole driving-chain is hard connection, and the working condition of gear is very abominable.
Mostly the all-hydraulic core drilling rig that uses on the market now is that hydraulic variable motor drives, and slows down through multiple-speed gearbox, again through the final stage transmission, drives at last and passes main shaft, the drilling rod of being clamped by the oild chuck construction of drilling.During drilling construction, rely on the interior oil cylinder of mast to drive the unit head that is attached to the mast outside and move up and down.Its complex structure, axle is many, gear is many, parts are many, each is higher relatively with gear rotational speed, noise is strong, calorific value is big, when carrying out deep hole construction, load is big, gripper chuck incessantly, the mast moment of flexure is big, is difficult to guarantee reliably working.
The utility model content
For solving above-mentioned shortcoming, the utility model provides a kind of big pulling force of bearing, compact conformation, and the number of gears is few, and noise is little, the deep hole all-hydraulic core drill unit head that calorific value is little.
The utility model adopts following technical scheme: a kind of deep hole all-hydraulic core drill unit head; Form by four hydraulic motors, casings, unit head carriage that the band rhombus frame of a fixed gear and middle main shaft and assistance for lifting unit head by large through-hole is housed; Wherein the rhombus frame connects a pair of hydraulic jack through tripod, and the unit head carriage connects guide rail simultaneously.
Said deep hole all-hydraulic core drill unit head by four fluid motor-driven, adopts gear drive, and power output is big, and rotary torque is big.
Said unit head casing is fixed on the unit head carriage, and the unit head carriage can slide on guide rail.
Said unit head carriage is connected with the rhombus frame with bearing pin, and rhombus frame two ends connect a pair of hydraulic jack through tripod.
The shift fork that is connected on the said rhombus frame, installing angle sensor on the unit head carriage, after rhombus frame (4) turned to certain angle, shift fork (5) promoted the overhang signal of the adjustment hydraulic jack that rotary angle transmitter (6) sends, and in time rhombus frame (4) is carried out leveling.
The deep hole all-hydraulic core drill unit head advantage that the utility model provides is: the main shaft latus rectum is big, compact conformation; It is big that four fluid motor-driven are transmitted power output rotary torques big, that provide, but have in light weight, the little stepless speed regulation of volume, realize overload protection; Use hydraulic jack easily to have controlled and pull out, transfer drilling tool speed, light control hole bottom pressure, realizing cores reconnoitres construction; The pulling force that hydraulic jack provides is symmetrically distributed, and guide rail is not produced moment of flexure, can bear the super large pulling force, finally realizes the heavy load deep hole construction.

The specific embodiment
Shown in accompanying drawing 1; A kind of deep hole all-hydraulic core drill unit head; Comprise that there is large through-hole casing 7, centre and fixedly main shaft 9, four hydraulic motors 1, the unit head carriage 2 that is connected with casing of gear wheel are housed; The unit head carriage is connected with rhombus frame 4 with bearing pin 8, and rhombus frame two ends connect a pair of hydraulic jack through tripod 3, and unit head carriage 2 moves up and down along guide rail 10.
Said four hydraulic motors 1 drive power shaft, power shaft drives gear wheel through gear drive and main shaft 9 rotates; Said unit head carriage 2 is connected with casing 7, is connected with rhombus frame 4 usefulness bearing pins 8 simultaneously; Said rhombus frame 4 two ends connect a pair of hydraulic jack through tripod 3.
Shown in accompanying drawing 2, rhombus frame 4 usefulness bearing pins 8 are connected on the unit head carriage 2, and rhombus frame 4 is connected with shift fork 5, and rotary angle transmitter 6 is installed on the unit head carriage 2, and rhombus frame 4 two ends are connected with tripod 3 usefulness axle, and tripod 3 upper ends connect hydraulic jack.
The end of said rotary angle transmitter 6 rocking arms is arranged in the draw-in groove of shift fork 4 ends; Said rhombus frame 4 is rotatable around bearing pin 8; Said tripod 3 upper ends connect hydraulic jack, and the hydraulic jack overhang at two ends can not make rhombus frame 4 rotate simultaneously; After said rhombus frame 4 corners reach certain angle, can make rotary angle transmitter 6 send signal, the signal that sends can be adjusted the overhang of hydraulic jack, to reach the purpose of leveling rhombus frame 4.
