But, in the process of drilling operation, owing to receive digging layer influence of geological factors; The phenomenon generation that drilling rod is lost often occurs,, need salvage it in case drilling rod is lost in the digging layer; Lose drilling rod and do not salvage, can have potential safety hazard, cause that all fire and gas accident take place.Traditional salvaging mode is that artificial making a breach at face salvaged.This salvaging mode wastes time and energy, inefficiency, and success rate is not high, can not drilling rod salvaged out fully.
Therefore, produce a kind of simple in structure, easy to operate, high efficiency, the screw bell that safety factor is high has vast market prospect.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of simple in structure, easy to operate, high efficiency, screw bell that safety factor is high.
The technical scheme of the utility model is such realization: a kind of screw bell; Comprise hydraulic jack; Described hydraulic jack is fixedly mounted on the liner plate, is symmetrically distributed with four bracing frames on the liner plate, the piston rod of hydraulic jack stretch out liner plate and through hook with threaded drill bit be set be connected; Drill bit is connected with the drilling rod fixator, offers the drilling rod connecting hole on the drilling rod fixator.
Described liner plate is the steel plate of 10 millimeters thick.
Described drill bit is connected with the drilling rod fixator through connecting rod, and the aperture of drill bit and connecting rod junction is 95 millimeters, and the diameter of connecting rod is 20 millimeters, and the length of connecting rod is 100 millimeters.
The diameter of described drilling rod fixator is 101 millimeters, and length is 500 millimeters.
The internal diameter of described drilling rod connecting hole is 6 millimeters.
Offer draw-in groove on the described drill bit.
Described piston rod is provided with retainer ring.
Described hydraulic jack is provided with draw ring.
Described bracing frame end is provided with supporting pad, and adjusting knob is installed on bracing frame.
The utlity model has following good effect: at first, this product structure is simple, and is easy to operate; Hydraulic jack is fixedly mounted on the liner plate, is symmetrically distributed with four bracing frames on the liner plate, the piston rod of hydraulic jack stretch out liner plate and through hook with threaded drill bit be set be connected; Drill bit is connected with the drilling rod fixator, offers the drilling rod connecting hole on the drilling rod fixator, and the pulling force after utilizing the drilling rod connecting hole and drilling rod being connected and the support force of bracing frame and hydraulic jack are to the reversal interlocking relay of drilling rod; Make the drilling rod of losing pull out the digging layer easily; High efficiency, laborsaving saving time, success rate is high; Be suitable for this product and solved the problem that drilling rod is lost, got rid of, improved the safety factor of underground work because of drilling rod is retained in the potential safety hazard in the digging layer.
