Abstract
An automatic guide rope tensioning device for a top drive type core driller comprises a guide rope (2) and a hydraulic oil cylinder (11). The upper end of the guide rope (2) is fixedly connected with the top of a drill tower (5); the lower end of the guide rope (2) is wound across a fixed pulley (9) and connected with the extending end of the hydraulic oil cylinder (11); and the other end of the hydraulic oil cylinder (11) is fixedly connected with a tower base and a platform (8). According to the automatic guide rope tensioning device for the top drive type core driller, by the adoption of the technical scheme, compared to the prior art, operation is simple, and the guide rope is good in tensioning effect and safe.
Description
Technical field
The invention belongs to geological prospecting apparatus field, it particularly relates to a kind of top drive formula rock-core borer is led
To the automatic tightening device of rope.
Background technology
Existing top is driven churn (as shown in Figure 1) and is mainly made up of following some parts: elevator 1,
Guide cords 2, lifting rope 3, tower top assembly pulley 4, boring tower 5, unit head 6, drilling rod 7, tower seat and flat
Platform 8.The operation principle that churn is driven on top is as follows: starts elevator 1, is stopped unit head 6 by lifting rope 3
In position, drilling rod 7 is installed, turns on the power 6, drive drilling rod 7 to rotate, progressively unclamp elevator
1, unit head 6 press against drilling rod 7 under gravity and is rotated down drilling.In whole drilling process,
Guide cords 2 make the direction that unit head 6 moves up and down be consistent.
In work process, guide cords 2 necessarily be in tensioned state, and tighten power and can not exceed guide cords
Bearing capacity.Guide cords routine is tightened and locking device is as shown in Fig. 1,2: guide cords 2
Upper end is fixed with tower top, and lower end is connected with elevator 1 after bypassing fixed pulley 9, starts elevator 1, is directed to
Rope 2 is tightened to suitable degree, is directed to rope 2 with conductor rope pressing plate 10 and locks, and disconnects guide cords
2 tighten and lock and finish with the connection of elevator 1, guide cords.When tightening guide cords, elevator 1
Must complete to sling unit head 6 simultaneously and tighten 2 two tasks of guide cords；Or complete to tighten guiding
Rope 2 simultaneously disconnects after locking, then unit head 6 of slinging, and two kinds of operating process are all quite loaded down with trivial details.
In addition, elevator 1 tightens the bad control of strength of guide cords 2, it is too small such as to tighten strength, guide cords
2 can not be played guide effect；As excessive in tightened strength, then guide cords are easy to damage.
Content of the invention
For solving the problems, such as in background technology, the invention provides a kind of top drive formula rock-core borer guide cords
Automatically tightening device.
The technical scheme is that a kind of top automatic tightening device of drive formula rock-core borer guide cords, bag
Include guide cords 2 and hydraulic jack 11；The upper end of guide cords 2 is fixedly connected with the top of boring tower 5,
Lower end is connected with the external part of hydraulic jack 11 after bypassing fixed pulley 9, the other end of hydraulic jack 11
It is fixedly connected with tower seat and platform 8.
Due to employing technique scheme, compared with prior art, the present invention is easy and simple to handle, guiding
Rope tightens that effect is good and safety.
Brief description
Fig. 1 is existing structural representation；
Fig. 2 is the partial enlargement structural representation of a part in Fig. 1；
Fig. 3 is the structural representation of the present invention；
Fig. 4 is the partial enlargement structural representation of b part in Fig. 3.
Specific embodiment
Embodiment
As shown in Figure 3, Figure 4, a kind of top automatic tightening device of drive formula rock-core borer guide cords, including
Guide cords 2 and hydraulic jack 11；The upper end of guide cords 2 is fixedly connected with the top of boring tower 5,
Lower end is connected with the external part of hydraulic jack 11 after bypassing fixed pulley 9, the other end of hydraulic jack 11
It is fixedly connected with tower seat and platform 8.The work process of this device is as follows: first holding according to guide cords 2
Loading capability, pre-sets to the input pressure of hydraulic jack 11, then hydraulic jack 11 is inputted
The hydraulic oil of relevant pressure value, makes hydraulic jack 11 shrink, and is directed to rope 2 and tightens, guide cords
2 enter working condition, and that is, the top automatic tightening device of drive formula rock-core borer guide cords has completed to tighten work
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.
