Description
Technical field
The plug-in and pull-off device of a kind of large-scale hinge of the utility model, belongs to mechanical engineering equipment field, particularly goliath.
Background technology
In rubber tyre gantry crane design, two structure members adopt stud connection conventionally.Between certain structures parts mounting or dismounting more frequent, need often plug bearing pin.For large-scale hinge, the hinge of such as goliath arm etc., tradition hinge pluggable mode is adopted suspension weight, carry out hinge to carry out the method for hammering, this method operating difficulties, labour intensity is large, and efficiency is low, hinge is also had to damage influence outward appearance, and be subject to the impact restriction of workshop.Therefore, need one simple to operate, can reduce hand labor intensity, raise the efficiency, and can adapt to the hinge plug-in and pull-off device of particular job occasion, to realize easily and efficiently hinge plug.
Utility model content
The purpose of this utility model is to provide a kind of large-scale hinge plug-in and pull-off device, and to solve the operating difficulties existing in large-scale hinge plug, labour intensity is large, inefficient problem.
The plug-in and pull-off device of a kind of large-scale hinge of the utility model, formed by frame, support orifice plate, pilot sleeve, sleeve positioning end cover assembly, screw motion mechanism, sleeve positioning end cover assembly is made up of bearing, bearing block, sleeve positioning end cover, bearing through bearing block by bolt consistent the linking into an integrated entity of axial centre with sleeve positioning end cover; Screw motion mechanism is made up of screw rod, thread jacket and hand wheel type rotating disk, thread jacket and screw rod are threaded connection, sleeve positioning end cover assembly location and installation is in one end of pilot sleeve, be fixed in frame, the other end of pilot sleeve is connected with support orifice plate, the screw axial concentric locating of screw motion mechanism is arranged in pilot sleeve, and screw rod one end coordinates the centre bore that is arranged on sleeve positioning end cover, and its termination is connected with rotating disc type handwheel; Pilot sleeve is enclosed within to hinge periphery, screw rod inserts in the axis through-hole of hinge, and the thread jacket of screw motion mechanism is connected with hinge corresponding end, drives hinge to rotate relative to screw rod by driving rotating disc type handwheel to order about thread jacket, do the motion of straight line advance and retreat, realize the plug of hinge.
Described hinge has axial central through hole.
There is the annular groove with screw motion mechanism thread jacket adaptation described hinge end.
There is chamfering described hinge end.
The utility model, by rotating handwheel, drives rotating disk and screw rod rotation, makes thread bush on screw rod, carry out rectilinear motion, because thread bush and hinge are fixed, realizes hinge inwall along sleeve on screw rod and carries out rectilinear motion.Therefore, in the time rotating handwheel, drive hinge to travel forward by screw flight transmission, hinge is penetrated and needs hinged orifice plate, reverse rotation can be extracted hinge, separates hinge member.Meanwhile, because guide effect and the hinge end of sleeve are processed with suitable chamfering, can realize more fast and accurately the contraposition in hinge and hole, make hinge pass in and out quickly and easily axis hole.The a pair of taper roll bearing being equipped with in bearing block, effectively reduces the frictional resistance while rotating handwheel.The utility model is for the plug of large-scale hinge, and simple to operate, convenient and swift, hand labor intensity is low, and efficiency is high, and can adapt to different operating occasion.

The specific embodiment
Now further illustrating by reference to the accompanying drawings the utility model is how specifically to implement:
The plug-in and pull-off device of a kind of large-scale hinge of the utility model, formed by frame, support orifice plate, pilot sleeve, sleeve positioning end cover assembly, screw motion mechanism, sleeve positioning end cover assembly is made up of bearings D, bearing block B, sleeve positioning end cover C, bearings D through bearing block B by bolt and consistent the linking into an integrated entity of sleeve end cap C axial centre; Screw motion mechanism is made up of screw rod F, thread jacket H and rotating disc type handwheel A, thread jacket H and screw rod F are threaded connection, sleeve positioning end cover assembly location and installation is in one end of pilot sleeve E, be fixed in frame, the other end of pilot sleeve E is connected with support orifice plate G, the axial concentric locating of screw rod F of screw motion mechanism is arranged in pilot sleeve E, and the cooperation of screw rod F one end is arranged in the centre bore of sleeve positioning end cover C, and its termination is connected with rotating disc type handwheel A; Pilot sleeve E is enclosed within to the periphery of hinge J, there is chamfering hinge end, to facilitate contraposition, screw rod F inserts in the axis through-hole of hinge hinge J, and the thread jacket H of screw motion mechanism is connected with hinge J corresponding end, rotate relative to screw rod F by driving rotating disc type handwheel A to order about the moving hinge J of thread jacket band H, do the motion of straight line advance and retreat, reach the object of plug hinge J.
Described hinge has axial central through hole.
There is the annular groove with screw motion mechanism thread jacket adaptation the described hinge end that has an axial central through hole.
Plug-in mounting hinge operating procedure of the present utility model is as follows:
1, manual rotation handwheel, by the rotation that rotarily drives screw rod F of rotating disk A.
2, the thread bush H that rotarily drives of screw rod F travels forward along screw rod F, because thread bush H and hinge J fix, hinge J travels forward along sleeve E.See accompanying drawing 1, accompanying drawing 4,
3, hinge J is through orifice plate G, and bearings D and sleeve E have the effect of guiding, until hinge J inserts orifice plate G completely, see accompanying drawing 5.
