Description
Technical field
The utility model is related to underground coal mine instrument field, and in particular to a kind of drilling rod stalk pulling device.
Background technology
During underground coal mine is drilled, often bored because embracing occurs in artificial and non-artificial factor, fall drilling rod accident, drilled
Team's group is handled using conventional drill, supporting drilling rod, sleeve.Occur embracing during construction drill and bore phenomenon first after rig
Rig rear is fixed using jack by side, then to the whole drill motor rotating speed of low-key, tries to have rotated forward and pulls out.Such as there is collapse hole serious
When construct one and drill again by former construction parameter below the drilling, then by above method dead man.If still embracing brill, it can make
With long-drawn-out hammer, drilling rod of swinging produces vibrations, reaches to embrace and is drilled loose dynamic, then dead man.Conventional treatment, which is embraced, bores, salvages the deficiency that drilling rod is present：①
Rig pressure is smaller, bores serious if embraced, it is impossible to extract drilling rod, easily falls to bore；2. it is artificial using the long-drawn-out drilling rod of long-drawn-out hammer, both took
When it is again laborious, have a strong impact on operating efficiency.
The content of the invention
For above-mentioned situation, the purpose of this utility model is to provide a kind of drilling rod stalk pulling device, simple to operate, security compared with
Height, bores it is possible to prevente effectively from embracing, falls the accidents such as drilling rod.
The technical solution of the utility model is as follows：A kind of drilling rod stalk pulling device, including two pieces of circular baffle plates setting up and down, institute
The center for stating two pieces of circular baffle plates is provided with drilling rod putting hole, and the opposite sides of two pieces of circular baffle plates is respectively fixed with hanger,
There are no less than two hydraulic jacks between two pieces of baffle plates, the hydraulic pressure hydraulic jack is set centered on drilling rod putting hole, hydraulic pressure
It is provided with oil cylinder and enters to press mouth and relief port for connected pipes.
It is preferred that, the hydraulic jack is provided with three, and setting triangular in shape is pulled out drilling rod strength uniformly, firmly stablized.
When the utility model high pressure stalk pulling device is operated, it first will enter to press mouth connecting to liquid interface by connected pipes and fisher
Connect, relief port is connected by oil pipe interface corresponding with pumping plant, feed pressure is transferred into minimum during work, then be slowly increased feed
Pressure, feed fluid enters hydraulic jack through fisher rear end three to liquid interface, and hydraulic jack jack-up has started to pull out drilling rod, when
When drilling rod is slowly released, stop increase feed pressure and slowly release drilling rod, after drilling rod extracts 600cm-650cm, start to shrink at
Oil cylinder, the oil pipe that oil return is connected through hydraulic jack relief port is backed into pumping plant, and rig behaviour is changed when drilling rod extracts 1 or 2
Make dead man.
Drilling rod stalk pulling device of the present utility model is simple to operate, easy left-hand seat, it is to avoid artificial frequently to go shock to bore using long-drawn-out hammer
Bar, security is higher, it is possible to reduce the potential safety hazard of artificial long-drawn-out drilling rod；Pressure is pulled out greatly by rising for hydraulic jack, can be effective
Solve to embrace and bore, fall the accidents such as drilling rod.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, a kind of drilling rod stalk pulling device, including two pieces of circular baffle plates 1 setting up and down, two pieces of circles
The center of baffle plate 1 is provided with drilling rod putting hole 2, and the opposite sides of two pieces of circular baffle plates 1 is respectively fixed with hanger 3, two pieces of circles
Triangular in shape between shape baffle plate 1 to be provided with three hydraulic jacks 6, the hydraulic pressure hydraulic jack 6 is set centered on drilling rod putting hole 2
Put, be provided with hydraulic jack 6 and enter to press mouth 4 and relief port 5 for connected pipes.
During concrete operations, pressure is supported using hydraulic jack 6, the drilling rod that drilling rod is penetrated into three hydraulic jack gaps is placed
Hole 2, is connected with drilling rod to be pulled out, and afterbody is fixed with stifled disk, the feed pressure of hydraulic jack 6 first is transferred into minimum, then be slowly increased
Feed pressure, feed fluid enters hydraulic jack 6 to liquid interface through fisher rear end three by entering to press mouth, and hydraulic jack 6 is opened
Begin to pull out drilling rod, when drilling rod is slowly released, stopped increase feed pressure and slowly release drilling rod, when drilling rod extracts 600cm-
After 650cm, hydraulic jack 6 is started to shrink at, the oil pipe that oil return is connected through the relief port 5 of hydraulic jack 6 is backed into pumping plant.
