Abstract
A mechanical rotating arm for transforming drill rods is characterized in that the mechanical rotating arm comprises a support and an inner hole which is matched with the bottom end of a rotating arm shaft is axially formed in the support. A bearing and a gear which are in a shaft fit with the bottom end of the rotating arm shaft are arranged inside the inner hole. The bearing and the gear is sleeved on a bottom shaft of the rotating arm shaft from top to bottom and an inner gear sleeve engages with the outside of the gear. A speed-changing box is arranged at the bottom end of the support and the power outlet end of the speed-changing box is connected with the inner gear sleeve. The centering of the drill rods can be adjusted by a method that a low-speed hydraulic motor is controlled by hydraulic ratio and the mechanical rotating arm is driven by the worm and worm speed-changing box. The mechanical rotating arm has the advantages that the structure is simple and reasonable, the problem of accuracy of centering the drill rods in assembly and disassembly can be solved, the automatic control of devices can be achieved, effective transformation and positioning of the drill rods can be realized, and accordingly, working efficiency can be greatly improved and manpower is saved.
Description
Technical field
The utility model belongs to field of mechanical technique, especially a kind of for shifting, load and unload the mechanical full wind-up of drilling rod.
Background technology
Engineering driller in the course of the work drill bit need to often promote and transfer, and the drilling rod quantity connecting with it reaches 30 more than, and the length of every drilling rod reaches 2.5 meters, and weight reaches 270 kilograms.
The duty of drill central makes to change, dismounting drilling rod efficiency becomes problem.And when changing drilling rod, conventionally adopt at present hydraulic pressure or motor to drive hoist engine, coordinate the mode of artificial lifting.This mode wastes time and energy, and positioning precision is low, and operation is loaded down with trivial details, larger to rig whole work influence, and production efficiency is not high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mechanical full wind-up for transferring drill for the above-mentioned state of the art, has simple and reasonable, easy to operate feature, can realize like a cork the transfer location of drilling rod, increases work efficiency.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of mechanical full wind-up for transferring drill, it is characterized in that: comprise bracing frame, on bracing frame, axially run through and be provided with the endoporus that insert a lower end for pivoting axle arm, in endoporus, be provided with the bearing and the gear that coordinate with the lower end axle of pivoting axle arm, described bearing and gear are nested with from top to down on the axle of the lower end of pivoting axle arm, gear external toothing is arranged with internal tooth casing, bottom at bracing frame is provided with gearbox, and the clutch end of gearbox is connected with internal tooth casing.
As improvement, bearings cover is installed between described bearing and gear, the inwall of described endoporus is provided with for bearings cover and supports fixing step.
As improvement, described gearbox adopts worm-and-wheel gear, and a side of gearbox is connected with hydraulic motor by flange.
Compared with prior art, the utility model has the advantage of: adopt hydraulic proportional to control low speed hydraulic motor, the method for the worm and gear gearbox driven rotary arm of high transmission ratio, regulates the centering of drilling rod.The utility model is simple and reasonable, and the precision problem of drilling rod centering while having solved preferably handling has been realized the automation of equipment and controlled, and effectively realizes the transfer location of drilling rod, greatly increases work efficiency, and has saved artificial.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the mechanical full wind-up for transferring drill of the present embodiment, comprise bracing frame 2, pivoting axle arm 1, gearbox 9 and hydraulic motor 4, on bracing frame 2, axially run through and be provided with the endoporus 21 that insert a lower end for pivoting axle arm 1, in endoporus 21, be provided with the bearing 5 and the gear 7 that coordinate with the lower end axle of pivoting axle arm 1, bearing 5 and gear 7 are nested with from top to down on the axle of the lower end of pivoting axle arm 1, gear 7 external toothings are arranged with internal tooth casing 8, gearbox 9 is arranged on the bottom of bracing frame 4, the clutch end of gearbox 9 is connected with internal tooth casing 8, bearings cover 6 is installed between bearing 5 and gear 7, on the inwall of endoporus 21, be provided with for bearings and overlap 6 fixing steps 22, bracing frame 2 is run through in the lower end of pivoting axle arm 1, bearing 5, bearings cover 6, gear 7, and be installed on endoporus 21 inside of bracing frame 2, gearbox 9 adopts the worm-and-wheel gear of high transmission ratio, one side of gearbox 9 is connected with hydraulic motor 4 by flange 3.
After runing rest is horizontal, the hydraulic motor 4 being connected by flange 3 drives gearbox 9, and gearbox 9 drives the internal tooth casing 8 of upper end, and internal tooth casing 8 driven gears 7 rotate, thereby driven rotary armshaft 1 rotates, and auxiliary its rotation of bearing 5.Because hydraulic motor 4 is selected low speed hydraulic motor, add that the gearbox 9 of high transmission ratio and electro_hydraulic proportional speed control control, during rotation-controlled armshaft 1 left rotation and right rotation, reach at a slow speed or state fast.And during low speed, because gearbox 9 adopts worm-and-wheel gears, therefore can realize the adjusting of minute angle, make drilling rod centering reach ideal effect.
