Description
Technical field
This utility model coal mine drilling machine equipment technical field, particularly belongs to the card on the hydraulic drive rig power head of a kind of colliery
Dish.
Background technology
Coal mining, geological drilling equipment have had and have developed faster.The gyroscope of rock-core borer is that tradition rock-core borer is defeated
Going out parts, its function is by passing to locking nut by the power of rig, and locking nut and chuck bonnet are by bolt and pin
Axle connects as one, the built-in slips of piston, and slips inclined-plane is loaded in collar surface groove, when chuck oil cylinder enters pressure oil,
Oil pressure makes piston move down, and drives collar to move down, and the clamping of compression spring slips, so that slips moves inward.Work as chuck oil cylinder
When being in off-load situation, under the effect of spring-return elastic force, piston top collar moving, slips is opened, and at this moment drilling rod is opened,
Such reciprocating action reaches to feed or act the purpose pulled out；The consumable accessory packing element that existing gyroscope is provided with, packing element is sealing member,
Installation degree of accuracy is high, and the most traditional gyroscope often changes a packing element needs the plenty of time, dismounting inconvenience, and installation steps are frequent,
Workload is big.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided the card on the hydraulic drive rig power head of a kind of colliery
Dish, overcomes the deficiencies in the prior art, reasonable in design, compact conformation, the internal consumable accessory glue used without tradition gyroscope of chuck
Cylinder, saves the step often changing packing element, has saved manual time.
The technical solution adopted in the utility model is as follows:
A kind of chuck on the hydraulic drive rig power head of colliery, including chuck bonnet, chuck body, piston and chuck protecgulum,
Described chuck body upper and lower end is correspondingly provided with chuck protecgulum, chuck bonnet respectively, and chuck body is central hole structure, chuck protecgulum, card
Forming cavity between dish bonnet and chuck body, described piston is arranged in chuck body, and piston has sealing ring, and piston inner hole is
Tapered hole is used for placing tapering slips, and described tapering slips upper and lower end carries out solid respectively by big torque-transmission disk, little torque-transmission disk
Fixed, by many spring supportings between tapering slips；On chuck bonnet, hydraulic fluid port is corresponding with hydraulic fluid port on chuck body, it is achieved pressure oil enters
Go out chuck body.
Described chuck protecgulum and chuck bonnet are fixed by sealing gasket and bolt with chuck body.
Described tapering slips is three slips self-centering type structures.
Compared with the prior art, the beneficial effects of the utility model are as follows:
This utility model is reasonable in design, compact conformation, is packing element inside traditional oild chuck, and packing element belongs to rapid wear
Part, needs often to change, reduces rig efficiency；This chuck is piston type, without packing element, it is to avoid consumable accessory, the fault of chuck
Rate is substantially reduced；This cartridge changing card watt-hour, it is not necessary to whole dismounting chuck, it is only necessary to chuck protecgulum is opened, slips is put
Enter, lock chuck protecgulum, convenient disassembly, be greatly saved the time, improve the efficiency of rig.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Seeing accompanying drawing, the chuck on the hydraulic drive rig power head of a kind of colliery, including chuck bonnet 1, chuck body 2, piston 3
With chuck protecgulum 7, described chuck body 2 upper and lower end is correspondingly provided with chuck protecgulum 7, chuck bonnet 1 respectively, and chuck body 1 is mesopore
Structure, forms cavity between chuck protecgulum 7, chuck bonnet 1 and chuck body 2, described piston 3 is arranged in chuck body 2, piston
Have on 3 sealing ring, piston 3 endoporus be tapered hole for placing tapering slips 5, described tapering slips 5 upper and lower end passes through respectively
Big torque-transmission disk 6, little torque-transmission disk 4 are fixed, by many spring supportings between tapering slips 5；Hydraulic fluid port and chuck on chuck bonnet 1
On body 2, hydraulic fluid port is corresponding, it is achieved pressure oil turnover chuck body 2；Described chuck protecgulum 7 and chuck bonnet 1 with chuck body 2 by close
Packing and bolt are fixed；Described tapering slips is three slips self-centering type structures.This utility model is reasonable in design, and structure is tight
Gathering, be packing element inside traditional oild chuck, packing element belongs to consumable accessory, needs often to change, reduces rig efficiency；This card
Dish is piston type, without packing element, it is to avoid consumable accessory, and the fault rate of chuck is substantially reduced；This cartridge changing card watt-hour, it is not necessary to whole
Individual dismounting chuck, it is only necessary to chuck protecgulum is opened, slips is put in, locks chuck protecgulum, convenient disassembly, significantly saves
The about time, improve the efficiency of rig.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model
Claimed scope is defined by appending claims and equivalent thereof.
