By adopting the above technical scheme, compare with prior art, the of the present invention structure is simpler, and it is very easy to install and remove, and the rig can not form any harm to the guide line cable at the despinning who starts in the twinkling of an eye or the drilling rod forms in tool joint, and the center of creeping into of unit head there is not the change when swinging, so can not cause any influence to creeping into the operation.

Description

Formula power head of core drilling machine guider is driven on a kind of top

Technical field

The invention belongs to geological prospecting apparatus field, it particularly relates to drive formula rock core drill motor-driven on a kind of top Power head guider.

Background technology

Existing top is driven churn (as shown in Figure 1) and is mainly made up of following some parts: elevator 101, Unit head guide rail 102, lifting rope 103, tower top assembly pulley 104, boring tower 105, unit head 106, drilling rod 107, tower seat and platform 108.Its operation principle is as follows: start elevator 101, will be dynamic by lifting rope 103 Power 106 is parked in appropriate location, installs drilling rod 107, turns on the power 106, drives drilling rod 107 to revolve Turning, progressively unclamp elevator 101, unit head 106 press against drilling rod 107 under gravity and is rotated down brill Enter.

In whole drilling process, the direction that unit head moves up and down must keep consistent, it is simply that top is driven formula and bored Mechanomotive force head conventional guide primary structure (as shown in Figure 2): be filled with guiding in the both sides of unit head Pulley 111, leading block 111 is encased in the unit head guide rail 102 on unit head 106 both sides, power Head guide rail 102 upper end is fixed with boring tower 105, and lower end is fixed with tower seat and platform 108, thus limits Unit head 106 can only move up and down, thus plays guide effect.

The unit head guide rail in churn guider is driven typically by the bigger specification of more than 8 meters in this top Channel-section steel is made, and this structure exists following drawback: 1, dismounting difficulty: the installation of bigger specification channel-section steel with Remove the most relatively difficult；2, structure is complicated: unit head guide rail must assure that vertical state when fixing up and down, After fixing, medial stability is poor, therefore must also install some guide rail struts additional in guide rail centre position, to add The stability of strong power head guide rail mid portion；3, unit head guiding edge is easily damaged: drilling process In, when starting moment or drilling rod encounters hard material in drilling process, unit head all can be formed necessarily Despining, this despining can make the leading block of unit head collide with unit head guiding edge, When this impact force is bigger, unit head guiding edge will damage, so that steering capability is deteriorated.

Summary of the invention

For solving the problem in background technology, the invention provides a kind of top and drive formula power head of core drilling machine and lead To device.

The technical scheme is that formula power head of core drilling machine guider is driven on a kind of top, including guiding Rope and leading block；Guide cords is positioned at unit head both sides, and its upper end is fixing with the top of boring tower to be connected, Its lower end is fixing with tower seat to be connected；Leading block is arranged on unit head both sides, and the top and bottom of every side are each Having two pulleys, the two pulley is for being arranged in juxtaposition, and guide cords is clipped between the two pulley.

Improving as one, described leading block can be set up one group, be distributed in the centre bit of unit head both sides Put, to obtain more preferable stability.

The further technical scheme of the present invention is: described guide cords is made up of the steel wire rope that intensity is higher.

Owing to have employed technique scheme, compared with prior art, present invention guide cords replaces Guiding rail of the prior art, eliminates original guide rail strut；And by original Guide rollers dress Enter the structure in astern power head guide rail to change Guide rollers into and clamp the structure of guide cords.Former owing to eliminating The guide rail strut come, the structure of this guider is simpler；Guide cords is by the higher steel wire rope of intensity Making, mounting or dismounting are the easiest；When guide cords is in tensioned state, the centre position of guide cords belongs to In elastic region, rig encounters hard material in startup moment or drilling rod in drilling process, and unit head is formed Certain despining, this despining makes leading block clip guide cords and forms swing by a small margin, Under the effect of guide cords elastic stage, the relative position of unit head quickly can be reduced, and this puts by a small margin Move and guide cords will not be formed any infringement, and when swinging, the center of creeping into of unit head does not becomes, therefore will not Have any impact to creeping into operation.

Detailed description of the invention

Embodiment

As shown in Figure 3, Figure 4, formula power head of core drilling machine guider is driven, including guide rope in a kind of top Rope 202 and leading block 211；Guide cords 202 is positioned at unit head 206 both sides, its upper end and boring tower The top of 204 is fixing to be connected, and its lower end is fixing with tower seat 208 to be connected；Leading block 211 is arranged on dynamic Power 206 both sides, the top and bottom of every side are respectively arranged with two pulleys, the two pulley for being arranged in juxtaposition, Guide cords 202 is clipped between the two pulley；Described leading block 211 can set up one group, is distributed in The center of unit head 206 both sides, to obtain more preferable stability；Described guide cords 202 is by by force Spend higher steel wire rope to make.

The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the enlightenment in the present invention Under the structure change made, every have with the present invention same or like as technical scheme, belong to Protection scope of the present invention.
