Abstract
The utility model relates to an anti-loosening and anti-turning device of a hinge pin, which is applied in the connection of the front frame and the rear frame of hinged engineering machinery, and comprises an upper hinge plate of a front frame, a positioning column, a washer, a bolt, a spring gasket, a positioning plate, a hinge pin, a lower hinge plate of the front frame, a pressure plate, a castle nut and a cotter pin. The positioning column is welded on the upper hinge plate of the front frame, the positioning plate is welded together with the hinge pin, and after the hinge pin is respectively inserted into the hinge holes of the upper hinge plate and the lower hinge plate of the front frame, and a U-shaped opening on the positioning plate locks the circumferential ring of the positioning column so as to prevent the hinge pin from being turned; and the pressure plate and the castle nut are screwed into the threaded part of the hinge pin shaft end, and after the castle nut is tightly screwed to a regulated position, the cotter pin passes through any radial hole of the hinge pin shaft end, so that the castle nut cannot rotate around the central axis of the hinge pin and retreats along the axial direction, so as to prevent the hinge pin from being loosened. By adopting the structure, the anti-loosening and anti-turning device of the hinge pin is simple to assemble, and is firm and effective.
Description
Technical field
The utility model relates to a kind of locking anti-rotation device of swivel pin, is applied to the connection of articulated engineer machinery front and back vehicle frame.
Background technique
Articulated engineer machinery for can be flexibly, stable, turn to reliably, usually the front and back vehicle frame is tied by swivel pin.The locking anti-rotation device of swivel pin commonly used is to adopt bolt positioning plate (being welded on the swivel pin) to be anchored on the last articulated slab of front frame, axially locating only, and the anti-rotation effect is poor; The swivel pin lower end adopts the follower bolt fixed structure to be installed on the following articulated slab bottom surface of front frame, and anti-rotation and fastening effect are bad.This swivel pin coupling gear in use for some time or under the abominable especially operating mode of vibratory impulse very easily because of the loosening play up and down that causes swivel pin of upper and lower part clamping bolt, and then cause the fixing bolt fracture, influence flexibility, stationarity and reliability that articulated engineer machinery turns to.
Summary of the invention
The purpose of this utility model is: provide a kind of under the abominable especially operating mode of vibratory impulse loosening, the not meeting of swivel pin of the clamping bolt locking anti-rotation device of play up and down, fundamentally solved disconnected, the caused mounting hole eccentric wear of the easy play of swivel pin of clamping bolt pine, a series of faults such as steering flexibility, stationarity and poor reliability.
The purpose of this utility model is achieved in that by articulated slab, pressing plate, castle nut and cotter pin under articulated slab, locating column, plain cushion, bolt, spring washer, positioning plate, swivel pin, the front frame on the front frame to be formed, locating column is welded on the front frame on the articulated slab, positioning plate and swivel pin are welded as a whole, after swivel pin inserted the hinging hole of articulated slab under articulated slab on the front frame, the front frame respectively, " U " type mouth on its positioning plate blocked the border of locating column to realize the anti-rotation of swivel pin; Pressing plate and castle nut screw in the helical thread portion of swivel pin axle head, after tightening to assigned position, castle nut penetrates in any one radial hole of swivel pin axle head with cotter pin, guarantee castle nut can not around the central axis of swivel pin rotate and vertically pine move back, thereby realize the locking of swivel pin.
Because the utility model adopts said structure, disconnected because of the clamping bolt pine, that the easy play of swivel pin caused a series of faults such as mounting hole eccentric wear have thoroughly been solved.Improved the flexibility that articulated engineer machinery turns to, stationarity and reliability, effectively simple.

Articulated slab 9. pressing plates 10. castle nuts 11. cotter pins under articulated slab 2. locating columns 3. plain cushions 4. bolts 5. spring washers 6. positioning plates 7. swivel pins 8. front frame on 1. front frame among the figure
Embodiment
Embodiment: form by articulated slab 8, pressing plate 9, castle nut 10 and cotter pin 11 under articulated slab on the front frame 1, locating column 2, plain cushion 3, bolt 4, spring washer 5, positioning plate 6, swivel pin 7, the front frame.As shown in Figure 1: at first locating column 2 is welded on the front frame on the articulated slab 1, positioning plate 6 is welded as a whole with swivel pin 7, insert the hinging hole of articulated slab under articulated slab on the front frame, the front frame respectively when swivel pin 7 after, the border that " U " type mouth on the positioning plate 6 is blocked locating column 2, use plain cushion 3, bolt 4, spring washer 5 that positioning plate 6 is fastening subsequently, guarantee the anti-rotation effect of swivel pin 7; Secondly pressing plate 9 and castle nut 10 are screwed in the helical thread portion of swivel pin 7 axle heads, after tightening to assigned position, castle nut 10 penetrates in any one radial hole of swivel pin 7 axle heads with cotter pin 11, castle nut 10 can not around the central axis of swivel pin 7 rotate and vertically pine move back, guarantee the anti-loosing effect of swivel pin 7.
The utility model can be guaranteed the locking anti-rotation effect of swivel pin, and assembling is simple, and is firm effective.
Claims (2)
1. the locking anti-rotation device of a swivel pin, form by articulated slab, pressing plate, castle nut and cotter pin under articulated slab, locating column, plain cushion, bolt, spring washer, positioning plate, swivel pin, the front frame on the front frame, locating column is welded on the front frame on the articulated slab, positioning plate and swivel pin are welded as a whole, swivel pin inserts respectively in the hinging hole of articulated slab under articulated slab on the front frame, the front frame, it is characterized in that: the border that " U " type mouth on the positioning plate blocks locating column, with plain cushion, bolt, spring washer that it is fastening.
