Abstract

A top-drive integrated core drill power head comprises an integrated box 201, a power head body 202, a gear box 203 and an input power box 204. The power head body 202, the gear box 203 and the input power box 204 are all installed in the integrated box 201. The power head body 202 is located at the bottom of the integrated box 201 and connected with a drill stem below. The gear box 203 is located over the power head body 203 and connected with the power head body 203. The input power box 204 is located over the gear box 203 and connected with the gear box 203. By adoption of the technical scheme, the path of power transmitted to the drill stem from a power output device is greatly shortened compared with the prior art; power is transmitted in the same direction, so that power waste is greatly reduced; and limit distance for vertical motion of the power head body is greatly increased, and the operating space is enlarged.

Description

A kind of top round-up accepted way of doing sth power head of core drilling machine

Technical field

A kind of the invention belongs to geological prospecting apparatus field, it particularly relates to top round-up accepted way of doing sth rock core drill Mechanomotive force head.

Background technology

Common rock-core borer (as shown in Figure 1) is to survey industry now to use to obtain a kind of rig the most universal, It is mainly made up of following some parts: input power 101, change speed gear box 102, frame 103, elevator 104th, power distributor box 105, drilling rod 106, unit head 107, main shaft 108, guide post 109, give Enter oil cylinder 110 and bevel gear phase 111.

Effect following (input power 101, change speed gear box 102, the frame 103 of common rock-core borer each several part It is not described herein):

1st, elevator 104 is typically used cooperatively with the boring tower that job site is built on the spot, is mainly used in lifting by crane Drilling rod 106, to facilitate the dismounting of drilling rod 106.

2nd, the power that power distributor box 105 is used for being transmitted through coming by change speed gear box 103 is assigned to bevel gear box 111 With elevator 104.

3rd, bevel gear box 111 passes to main shaft after the power that power distributor box 105 is transmitted through turns 108.

4th, main shaft 108 hollow, to load drilling rod 106, the upper end of main shaft 108 and unit head 107 It is connected, the power that can be transmitted through coming by bevel gear box 111 passes to unit head 107.

5th, unit head 107 accepts the power drive drilling rod that bevel gear box 111 is transmitted through coming by main shaft 108 106 rotations.

6th, feed oil cylinder 110 makes unit head 107 move up and down.

7th, drilling rod 106 produces rotary motion in the presence of unit head 107, in feed oil cylinder 110 The lower generation of effect moves up and down, and is downwards drilling, is then to take out upwards.

8th, guide post 109 ensures that the direction that unit head 107 moves up and down is consistent.

In sum, the path that power is delivered to drilling rod is: input power 101 → change speed gear box 102 → point Dynamic case 105 → bevel gear box, 111 → main shaft, 108 → unit head, 107 → drilling rod 106, power transfer path Longer, and when through bevel gear box 111, also change power direction and (become perpendicular by transverse rotation To rotation), cause power waste；The stroke that unit head 107 moves up and down is subject to feed oil cylinder 110 volume Determine the restriction of stroke, move distance is too short, move distance is excessive upwards also can make stablizing of unit head 107 Property becomes very poor.

Content of the invention

For solving the problems, such as in background technology, the invention provides a kind of top round-up accepted way of doing sth rock-core borer power Head.

The technical scheme is that a kind of top round-up accepted way of doing sth power head of core drilling machine, including overall case 201st, unit head 202, change speed gear box 203 and input power 204；Unit head 202, change speed gear box 203 and Input power 204 is installed in overall case 201；Unit head 202 is located at overall case 201 bottom, and It is connected with the drilling rod of lower section；Change speed gear box 203 is located at directly over unit head 202 and both are connected, and input is dynamic Power 204 is located at directly over change speed gear box 203 and both are connected.

Improve as a kind of, described top round-up accepted way of doing sth power head of core drilling machine also includes boom hoisting 205, Boom hoisting 205 is located at the top of overall case 201, is used for overall case 201 of slinging.

The further technical scheme of the present invention is: described top round-up accepted way of doing sth power head of core drilling machine also includes Several balancing weights 206；Balancing weight 206 is located inside overall case 201, can suitably increase and decrease its quantity with The weight of adjustment total.

The present invention further technical scheme is: described top round-up accepted way of doing sth power head of core drilling machine also wraps Include guider 207, guider 207 is located at overall case 201 both sides, movable with overall case 201 Ground connects, and is used for guaranteeing that pushing up round-up accepted way of doing sth power head of core drilling machine can vertically move up and down, and ensures Its stability.

Due to employing technique scheme, compared with prior art, the power of the present invention is by power The path that output device is delivered to drilling rod greatly shortens, and power output does not change direction so that power is unrestrained Expense greatly reduces；The restricted distance that unit head moves up and down greatly increases, and increased working place.
