Abstract
Disclosed is a drill rod lifter of a drill jumbo. The drill rod lifter of the drill jumbo comprises a front drill rod lifter and a middle drill rod lifter, wherein front bearings are installed inside a front drill rod lifting sleeve of the front drill rod lifter, middle bearings are installed inside a middle drill rod lifting sleeve of the middle drill rod lifter, and the front bearings and the middle bearings are needle bearings. According to the drill rod lifter of the drill jumbo, different mechanics principles are adopted an existing drill rod lifter. Due to the fact that the bearings are additionally arranged inside the sleeves of the front drill rod lifter and the middle drill rod lifter respectively, the drill rod lifters can overcome friction in the high-speed spinning process. Due to the fact that the bearings are made of high-strength materials, abrasion resistance can also be guaranteed, transmission of friction is overcome, drill rod, loss of a jackdrill and a drill rod tail is reduced, and investment is low.
Description
Technical field
The present invention relates to the constructional device using on a kind of jumbo, especially a kind of jumbo puncheon centralizing device of slidingtype.
Background technology
On domestic existing jumbo puncheon centralizing device, it is rigid puncheon centralizing device, i.e. mounting bush on jumbo puncheon centralizing device, because front puncheon centralizing device is to be fixed on forward beam to come directly towards upper motionless, hammer drill and middle puncheon centralizing device are done back and forth movement, therefore the longer vibration of distance is more severe, and hard and hard friction is to puncheon centralizing device lining and drill steel serious wear, and the short time must be changed, greatly increase cost, improved energy consumption.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of jumbo puncheon centralizing device of slidingtype, has overcome the transmission of frictional force, has reduced hammer drill, drill steel and bit shank loss, invests little.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of jumbo puncheon centralizing device, comprise front puncheon centralizing device and middle puncheon centralizing device,
Before front puncheon centralizing device, hold up fore bearing is installed in drill sleeve;
The centre of middle puncheon centralizing device is held up intermediate bearing is installed in drill sleeve.
In front puncheon centralizing device, fore bearing and before hold up drill sleeve to closely cooperate, hold up drill sleeve before making front the first support fastening together with front the second support by front bolt hole, front bearing is fixedly mounted on forward beam slide plate.
In middle puncheon centralizing device, intermediate bearing and centre hold up drill sleeve to closely cooperate, and in the middle of making by middle screw keyhole, the first support is held up drill sleeve in fastening centre together with middle the second support, and intermediate support is fixedly mounted on forward beam slide plate.
Fore bearing and intermediate bearing are needle bearing.
A kind of jumbo puncheon centralizing device provided by the invention, on existing puncheon centralizing device, utilize different mechanics principles, owing to respectively increasing bearing in the lining at front puncheon centralizing device and middle puncheon centralizing device, can guarantee puncheon centralizing device overcome friction when High Rotation Speed, bearing itself is made by high-strength material, also can guarantee to rely polishing machine, overcome the transmission of frictional force, can not add galling to drill steel, reduce hammer drill, drill steel and bit shank loss, invest little; Solved import and domestic jumbo problem, changed internal and overseas at technical barrier of the same trade, to user's production, standby redundancy material consumption, promoted higher level, economic benefit is specially for considerable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structural representation of puncheon centralizing device before the present invention;
Fig. 2 is the structural representation of puncheon centralizing device in the middle of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, the present invention includes front puncheon centralizing device 1 and middle puncheon centralizing device 2,
Before front puncheon centralizing device 1, hold up fore bearing 1-2 is installed in drill sleeve 1-1;
The centre of middle puncheon centralizing device 2 is held up intermediate bearing 2-2 is installed in drill sleeve 2-1.
In front puncheon centralizing device 1, fore bearing 1-2 and before hold up drill sleeve 1-1 to closely cooperate, before making front the first support 1-3 fastening together with front the second support 1-6 by front bolt hole 1-4, hold up drill sleeve 1-1, front bearing 1-5 is fixedly mounted on forward beam slide plate, before bolt hole 1-4 makes front the first support 1-3 fastening together with front the second support 1-6 before utilizing, hold up drill sleeve 1-1, avoid fore bearing 1-2 to rotate, the drill steel rotation that matches with fore bearing 1-2 inner circle, has overcome rigid frictional force.
In middle puncheon centralizing device 2, intermediate bearing 2-2 and centre hold up drill sleeve 2-1 to closely cooperate, in the middle of making by middle screw keyhole 2-4, the first support 2-3 holds up drill sleeve 2-1 in fastening centre together with middle the second support 2-6, intermediate support 2-5 is fixedly mounted on forward beam slide plate, utilize middle screw keyhole 2-4 to make middle the first support 2-3 hold up drill sleeve 21-1 in fastening centre together with middle the second support 2-6, avoid intermediate bearing 2-2 to rotate, the drill steel rotation that matches with fore bearing 1-2 inner circle, has overcome rigid frictional force.
Fore bearing 1-2 and intermediate bearing 2-2 are needle bearing.
It is upper motionless that front puncheon centralizing device 1 is fixed on forward beam top, and hammer drill and middle puncheon centralizing device 2 are done back and forth movement 5.
The endoporus of fore bearing 1-2 and intermediate bearing 2-2 is determined through size according to drill steel is outer, after its endoporus wearing and tearing greatly, directly affects the damages such as hammer drill, bit shank, drill steel, after endoporus wearing and tearing are large, must change fore bearing 1-2 and intermediate bearing 2-2.
