Description

Lifting device for rotary drilling rig

Technical Field

The utility model relates to a dig rig apparatus technical field soon, in particular to dig rig soon and use elevator.

Background

At present, a rotary drilling rig is widely applied to basic construction engineering such as municipal construction, highway bridges, high-rise buildings and the like as a construction machine suitable for boring operation in the building basic engineering. The rotary drilling rig has the advantages of large installed power, large output torque, large axial pressure, flexibility, high construction efficiency, good pore-forming quality and the like, is widely used in the field of engineering construction, becomes main pore-forming equipment for engineering construction, and can be matched with various drilling tools to be applied to pore-forming operation of dry type (matched with a short spiral drilling tool) or wet type (matched with a rotary bucket) and rock stratum (matched with a core drill). In the actual working process, the steel wire rope penetrates through the hoisting drill rod to drive the drill bit to rotate, so that the purpose of forming holes is achieved.

The existing elevator comprises an upper connector 1 ', a cylinder 2' and a lower connector 3 ', the bottom end of the lower connector 3' is of a slotted structure (shown in attached drawing 1), a drill rod is inserted into a slot and fixed by a pin, and the structure is high in production and processing cost on one hand, and on the other hand, when the elevator is used, the bottom end of the elevator is limited by an outer cylinder wall and cannot be further downwards detected along with the drill rod.

Therefore, it is necessary to provide an elevator for a rotary drilling rig to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a dig elevator soon for rig to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a dig elevator for rig soon, includes connector, barrel and lower connector, goes up connector and barrel fixed connection, and a recess has been seted up on the upper connector surface, and lower connector sets up to rotate through bearing and barrel and is connected, lower connector includes connecting portion, fixed axle and links up the portion, the fixed axle is fixed to be set up on the connecting portion top, links up the fixed setting in the connecting portion bottom, link up the portion and be square piece, and the connecting hole has been seted up on the surface.

Preferably, the length of the square block is smaller than the diameter of the connecting part and is matched with the drill rod.

Preferably, the connecting portion is integrally formed with the joining portion.

Preferably, two grooves are formed in the surface of the upper connecting body, so that the connection strength of the main winding steel wire rope and the elevator is guaranteed.

The utility model discloses a technological effect and advantage: the bottom end of the lower connecting part of the elevator is set to be a square block, and the square block is directly inserted into the drill rod and fixedly connected with the drill rod, so that the elevator can be used without being limited by the outer cylinder wall, can be used for exploring deeper places along with the drill rod, and is stopped until the bottom end of the connecting part abuts against the outer cylinder wall, and the drilling depth is improved; since the structure is simplified, the production cost can be reduced.
