Abstract
The utility model relates to a pin-pulling apparatus, particularly a hydraulic pin-pulling apparatus used for a larger pin shaft on a large machine. The utility model comprises a force-bearing truss which is formed by the method that an upper and a lower two transverse plates are fixed by a pulling rod, the upper part in the middle of the force-bearing truss is provided with a hydraulic jack, one end of the hydraulic jack is supported on the lower bottom surface of the upper transverse plate, and the other end is supported on the upper top surface of one pressing plate. The pressing plate is fixedly connected a top pressing plate positioned at the lower part of the lower transverse plate by a pressure lever glidingly matching with a through hole of the lower transverse plate, and a pin-pulling bolt glidingly matches with a centre hole of the lower transverse plate and penetrates a centre hole of the top pressing plate and then extends out the top pressing plate. The utility model has the advantages of simple and compact structure, convenient operation, labor saving, and time saving.
Description
The utility model relates to a kind of utensil of pulling pin, particularly a kind of hydraulic pin remover that is used to dismantle on the big machinery than the major diameter bearing pin.
As everyone knows, to dismantle be very difficult to larger-diameter bearing pin on the big machinery, and the three roller centring machines that hot-working is used as steel pipe have two main shafts, are furnished with the bearing pin that diameter is 25mm, in case the main shaft string is moving.Because under the effect of repeated loading, can cause the bearing pin bending, this brings very big difficulty to dismantlement work.Usually because of can not pulling out bearing pin, can only remove bearing pin with drill bit bearing pin boring processing, but can therefore damage main shaft.
The purpose of this utility model is to provide a kind of hydraulic pin remover, can pull out larger-diameter bearing pin on the big machinery convenient and strength-savingly, and not damage relevant parts.
For achieving the above object, the utility model adopts following technical proposals: in the utility model and the prior art load framework commonly used the same include by about two transverse slats fixedly constitute the load framework by pull bar.It is characterized in that load framework middle upper portion arrangement hydraulic jack, hydraulic jack one end bearing is in the bottom surface of upper cross plate, and the other end is supported on end face on the block pressur plate; Pressing plate is by fixedlying connected the top pressing board that is positioned at the lower cross plate below with the depression bar that lower cross plate through hole cunning is joined; There are pull pin bolt and a lower cross plate centre bore cunning to join, and pass the centre bore of a pressing plate and stretch out outside the top pressing board.During use, process on the bearing pin that will be pulled out and screw that the bolt of pulling pin matches, the screw on will pull pin then bolt and the bearing pin spins, and starts hydraulic jack, just can extract bearing pin.
Load framework of the present utility model can design 2～4 pull bars, and the screw of pull bar lower end screw thread and lower cross plate spins, and pull bar upper end thread segment passes the perforation on the upper cross plate and spun by nut.Pressing plate can be fixedlyed connected with top pressing board by 2～4 depression bars, and the upper end bearing pin of depression bar and the perforation cunning on the pressing plate are joined, and the screw thread of depression bar lower end and the screw of top pressing board spin.Adopt said structure, being connected between the connection of load framework and pressing plate and the top pressing board, easy for removal and installation.
The utility model has following conspicuous advantage compared with prior art: adopt the utility model, larger-diameter bearing pin on the energy big machinery for convenience detach.The utility model is simple and compact for structure, and is easy to use, time saving and energy saving.
Accompanying drawing is the structural representation of an embodiment of the utility model.
An optimum implementation of the present utility model is: referring to accompanying drawing, this hydraulic pin remover includes by two transverse slats up and down 2,8 and fixedly constitutes the load framework by pull bar 3, load framework middle upper portion is settled hydraulic jack 4, hydraulic jack 4 one end bearings are in the bottom surface of upper cross plate 2, and the other end is supported on end face on the block pressur plate 5; Pressing plate 5 is by fixedlying connected the top pressing board 9 that is positioned at lower cross plate 8 belows with the depression bar 6 that lower cross plate 8 through hole cunnings are joined; There is a bolt 7 of pulling pin to join, and passes the centre bore of top pressing board 9 and stretch out outside the top pressing board 9 with lower cross plate 8 centre bore cunnings.The load framework has two pull bars 3, and the screw thread of pull bar 3 lower end screw threads and lower cross plate 8 spins, and pull bar 3 upper end thread segments pass the perforation on the upper cross plate 2 and spun by nut 1.Pressing plate 5 is fixedlyed connected with top pressing board 9 by two depression bars 6, and the upper end bearing pin of depression bar 6 and the perforation cunning on the pressing plate 5 are joined, and the screw thread of depression bar 6 lower ends and the screw of top pressing board 9 spin.
