Description
Technical field
The utility model belongs to hydraulic tunnel drilling machine equipment technical field, particularly relates to a kind of novel hydraulic underground drill rig clamper.
Background technology
Underground drill rig is specifically designed to the rig carrying out work of creeping in underground passage, and rig is all equipped with clamper usually, and its Main Function is drilling rod in protective hole, prevents drilling rod slippage, or coordinate unit head to carry out the automatic dismantling of drilling rod.Because clamper is easy to use, the power that accommodates is large, it is made to be widely adopted.
But existing clamper is only provided with the thrust mechanisms such as flexible member, flexible member is flexible frequent, and easily fatigue damage occurs, application life is short, and replacement operation is loaded down with trivial details, brings very big inconvenience to construction; In addition, the chucking power that flexible member nature determines clamper immobilizes, and can not, along with the chucking power of industrial and mineral demand change clamper, make the clamper scope of application limited.
Utility model content
The purpose of this utility model is to provide the novel hydraulic underground drill rig clamper that a kind of structure is simple, chucking power can be in harmonious proportion good clamping effect.
For achieving the above object, the utility model adopts following technical scheme: a kind of novel hydraulic underground drill rig clamper, comprise the end cap of cylinder body and cylinder ends, be provided with the left oil pocket at clamping chamber and clamping two ends, chamber and right oil pocket in described cylinder body, cylinder side wall is provided with the left clamping oilhole communicated with left oil pocket, the right clamping oilhole communicated with right oil pocket; Clamping is provided with slips in chamber, and be respectively equipped with the left piston and right piston that connect with slips both sides in left oil pocket and right oil pocket, left piston outer face apical grafting has the left disc spring of being installed by left end cap, and right piston outer face apical grafting has the right disc spring of being installed by right end cap.
Be provided with the oil duct being communicated with left oil pocket and right oil pocket in described cylinder body, cylinder side wall be provided with communicate with oil duct unclamp oilhole.
It is two right that the quantity of described left disc spring and right disc spring is, and often pair of disc spring is connected by outer.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model comprises the end cap of cylinder body and cylinder ends, and be provided with the left oil pocket at clamping chamber and clamping two ends, chamber and right oil pocket in described cylinder body, cylinder side wall is provided with the left clamping oilhole communicated with left oil pocket, the right clamping oilhole communicated with right oil pocket; Clamping is provided with slips in chamber, the left piston and right piston that connect with slips both sides is respectively equipped with in left oil pocket and right oil pocket, left piston outer face apical grafting has the left disc spring of being installed by left end cap, right piston outer face apical grafting has the right disc spring of being installed by right end cap, its structure is simple, during use, being connected high-pressure oil pipe at left clamping oilhole, right clamping oilhole with unclamping on oilhole respectively, first in slips, loading drilling rod; Open oil cylinder again, high-pressure oil pipe is by left clamping oilhole and right clamping oilhole fuel feeding in oil pocket and right oil pocket left respectively, and left piston and right piston inwardly promote slips, to clamp drilling rod under high-voltage oil liquid promotes; Then, when needing to unload drilling rod, stop fuel feeding in oil pocket and right oil pocket left, then by unclamping oilhole to fuel feeding in oil duct, to promote left piston and the outwards movement of right piston, unclamp slips and drilling rod, easy and simple to handle; Meanwhile, when the clamping dynamics of left disc spring and right disc spring is inadequate, promote left piston by high-voltage oil liquid and right piston enters secondary clamped condition, and change chucking power by the oil pressure adjusting high-voltage oil liquid, reach required clamping force, chucking power is adjustable, use flexibly, the scope of application is wide.
2, the oil duct being communicated with left oil pocket and right oil pocket is provided with in cylinder body, cylinder side wall be provided with communicate with oil duct unclamp oilhole, when needing to unload drilling rod, stop fuel feeding in oil pocket and right oil pocket left, then by unclamping oilhole to fuel feeding in oil duct, to promote left piston and the outwards movement of right piston, unclamp slips and drilling rod, easy and simple to handle, action is fast sensitive, reliable operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Novel hydraulic underground drill rig clamper as shown in Figure 1, it comprises the clamping chamber 13 in cylinder body 1 and cylinder body 1, left oil pocket 11 and right oil pocket 12 is respectively equipped with at clamping two ends, chamber 13, be provided with the oil duct 10 being communicated with left oil pocket 11 and right oil pocket 12 in cylinder body 1, cylinder body 1 sidewall is provided with the left clamping oilhole 91 communicated with left oil pocket 11, the right clamping oilhole 92 communicated with right oil pocket 12, communicate with oil duct 10 unclamp oilhole 93.
Slips 8 is provided with in clamping chamber 13, the left piston 4 and right piston 7 that connect with slips 8 both sides is respectively equipped with in left oil pocket 11 and right oil pocket 12, left piston 4 outer face apical grafting has the left disc spring 3 of being installed by left end cap 2, and right piston 7 outer face apical grafting has the right disc spring 6 of being installed by right end cap 5.
In the present embodiment, it is two right that the quantity of left disc spring 3 and right disc spring 6 is, and often pair of disc spring is connected by outer, and two pairs of adjacent disc springs are connected by the interior edge of inner side disc spring; The quantity of left disc spring 3 and right disc spring 6 also can adjust as required.
When the utility model uses, respectively at left clamping oilhole 91, right clamping oilhole 92 with unclamp on oilhole 93 and be connected high-pressure oil pipe, specific works process is: first, in slips 8, load drilling rod; Secondly, open oil cylinder, high-pressure oil pipe is by left clamping oilhole 91 and right clamping oilhole 92 fuel feeding in oil pocket 11 and right oil pocket 12 left respectively, and left piston 4 and right piston 7 inside promotion slips 8 under high-voltage oil liquid promotes, to clamp drilling rod; Then, when needing to unload drilling rod, stop fuel feeding in oil pocket 11 and right oil pocket 12 left, then by unclamping oilhole 93 to fuel feeding in oil duct 10, to promote left piston 4 and right piston 7 outwards movement, unclamp slips 8 and drilling rod.
In the utility model, the state of left disc spring 3 and right disc spring 6 is one-level clamped condition, when the one-level clamping dynamics of left disc spring 3 and right disc spring 6 is inadequate, secondary clamped condition is entered by high-voltage oil liquid promotion left piston 4 and right piston 7, and change chucking power by the oil pressure adjusting high-voltage oil liquid, reach required clamping force.
