Description
Technical field
The utility model provides a kind of bushing pipe extractor, belongs to bushing pipe puller field.
Background technology
In coal mine hydraulic supporting, be widely used quick joining type high-pressure rubber pipe, quick joining type high-pressure rubber pipe is comprised of wire rubber pipe, bushing pipe, sleeve three parts, and this three part, by after manual assembly, compresses with buckle machine.In assembling process, often occur, bushing pipe is not in place need pull out bushing pipe to ressemble.
Currently available technology defect is: one, and the strength that bushing pipe is extracted needs is larger, so the inconvenience of choosing; Its two, it is less that bushing pipe exposes sleeve part, uses the instruments such as pliers to be not easy to clamp.
Utility model content
The utility model object is to provide a kind of bushing pipe extractor, pulls out bushing pipe comparatively laborsaving, can clamp preferably bushing pipe and expose sleeve part.
Bushing pipe extractor described in the utility model, comprises threaded cylinder, is provided with top cover and pusher dog, in top cover, be provided with track, pusher dog outer surface is provided with slide block, and pusher dog is positioned at top cover inside, and cooperatively interacts by slide block and track and top cover, top cover one end is provided with plane bearing, pusher dog one end is provided with screw, and threaded cylinder passes plane bearing and screw, and coordinates with screw, the pusher dog other end is provided with pawl, and the neck shape of claw shape and bushing pipe one end adapts.
Described bushing pipe extractor, pusher dog is provided with two pawls, two pawls all claim circular arc, and made by elastomeric material with pawl coupling part, so outwards break two pawls, make it apart from expansion, to guarantee that pawl can buckle into the depression that bushing pipe exposes the neck neck portion of sleeve, then top cover is enclosed within to pusher dog outside, top cover internal diameter and pusher dog external diameter adapt, both guaranteed that top cover was enclosed within the pawl of pusher dog behind pusher dog outside and cannot opens again, prevented that pawl from deviating from the depression of neck, after under top cover is overlapped completely, make the end face under its cover withstand sleeve corresponding end-faces, finally by threaded cylinder through plane bearing and screw in the screw of pusher dog, then hold top cover, and use instrument simultaneously or in threaded cylinder one end, perpendicular handle is set, rotate threaded cylinder, at this moment threaded double-screw bolt and screw generation relative displacement, because sleeve is withstood by top cover, so bushing pipe can be pulled out under the drive of pusher dog dewclaw in sleeve, pawl of the present utility model can effectively catch bushing pipe to expose sleeve part, and top cover can guarantee that pawl do not deviate from, very reliable, and coordinate with screw by threaded cylinder, bushing pipe is extracted, and can increase moment by instruments such as handles, reduced greatly staff's working strength, very laborsaving.
Described bushing pipe extractor, threaded cylinder, the one end through top cover and pusher dog is not provided with handle, and handle is perpendicular to threaded cylinder.Can make to increase moment, make convenient bushing pipe is screwed out of staff.
The utility model compared with prior art beneficial effect is:
Described bushing pipe extractor, pusher dog is provided with two pawls, two pawls all claim circular arc, and made by elastomeric material with pawl coupling part, so outwards break two pawls, make it apart from expansion, to guarantee that pawl can buckle into the depression that bushing pipe exposes the neck neck portion of sleeve, then top cover is enclosed within to pusher dog outside, top cover internal diameter and pusher dog external diameter adapt, both guaranteed that top cover was enclosed within the pawl of pusher dog behind pusher dog outside and cannot opens again, prevented that pawl from deviating from the depression of neck, after under top cover is overlapped completely, make the end face under its cover withstand sleeve corresponding end-faces, finally by threaded cylinder through plane bearing and screw in the screw of pusher dog, then hold top cover, and use instrument simultaneously or in threaded cylinder one end, perpendicular handle is set, rotate threaded cylinder, at this moment threaded double-screw bolt and screw generation relative displacement, because sleeve is withstood by top cover, so bushing pipe can be pulled out under the drive of pusher dog dewclaw in sleeve, pawl of the present utility model can effectively catch bushing pipe to expose sleeve part, and top cover can guarantee that pawl do not deviate from, very reliable, and coordinate with screw by threaded cylinder, bushing pipe is extracted, and can increase moment by instruments such as handles, reduced greatly staff's working strength, very laborsaving.
Described handle, can make to increase moment, makes convenient bushing pipe is screwed out of staff.

The specific embodiment
Below in conjunction with the utility model, the utility model embodiment is described further:
Embodiment 1: as shown in Figure 1, bushing pipe extractor described in the utility model, comprises double-screw bolt 1, be provided with top cover 2 and pusher dog 3, in top cover 2, be provided with track, pusher dog 3 outer surfaces are provided with slide block, pusher dog 3 is positioned at top cover 2 inside, and by slide block and track and top cover, cooperatively interact, top cover 2 one end are provided with plane bearing 8, and pusher dog 3 one end are provided with screw 6, double-screw bolt 1 is through plane bearing 8 and screw 6, and coordinate with screw 6, pusher dog 3 other ends are provided with pawl 5, and the neck shape of pawl 5 shapes and bushing pipe 4 one end adapts.
Embodiment 2: on the architecture basics described in embodiment 1, double-screw bolt 1 is not provided with handle 7 through one end of top cover 2 and pusher dog 3, and handle 7 is perpendicular to double-screw bolt 1.
Operating procedure and operation principle:
Described bushing pipe extractor, pusher dog 3 is provided with two pawls 5, two pawls 5 all claim circular arc, and made by elastomeric material with pawl 5 coupling parts, so outwards break two pawls 5, make it apart from expansion, to guarantee that pawl 5 can buckle into the depression that bushing pipe 4 exposes the neck neck portion of sleeve 9, then top cover 2 is enclosed within to pusher dog 3 outsides, top cover 2 internal diameters and pusher dog 3 external diameters adapt, both guaranteed that top cover 2 was enclosed within the outside pawl of pusher dogs afterwards of pusher dog 3 and cannot opens again, prevented that pawl 5 from deviating from the depression of neck, after under top cover 2 is overlapped completely, make the end face under its cover withstand sleeve 9 corresponding end-faces, finally by double-screw bolt 1 through plane bearing 8 and screw in the screw 6 of pusher dog 3, then hold top cover 2, and use instrument simultaneously or in double-screw bolt 1 one end, perpendicular handle 7 is set, rotation double-screw bolt 1, at this moment there is relative displacement with screw 6 in double-screw bolt 1, because sleeve 9 is withstood by top cover 2, so bushing pipe can be pulled out under the drive of pusher dog 3 dewclaws 5 in sleeve 9, pawl 5 of the present utility model can effectively catch bushing pipe 4 to expose sleeve 9 parts, and top cover 2 can guarantee that pawl 5 do not deviate from, very reliable, and coordinate with screw 6 by double-screw bolt 1, bushing pipe 4 is extracted, and can increase moment by instruments such as handles 7, reduced greatly staff's working strength, very laborsaving.
