Abstract
The invention discloses an anti-rotation fixing device for hinge pins. The anti-rotation fixing device comprises at least one no-head hinge pin (3), at least two positioning sleeves (4), vertical pins (5) and cotter pins (7). The no-head hinge pin (3) is installed in the connection position of a connection part I (1) and a connection part II (2). The positioning sleeves (4) are installed at the two ends of the no-head hinge pin (3). The positioning sleeves (4) are in series connection with the no-head hinge pin (3) through the vertical pins (5). Meanwhile, the vertical pins (5) are fixed to the cotter pins (7) through gaskets (6). According to the anti-rotation fixing device, abrasion or shear fracture of the cotter pins can be avoided. The connection installation efficiency of the hinge pins is improved, and a fixing function on the pin ends of the hinge pins can be effectively achieved.
Description
Technical field
The present invention relates to a kind of tower machine structural connection, specifically a kind of pin shaft anti-rotation fixing device.
Background technique
Tower machine anatomical connectivity is generally divided into two kinds: high strength exploitation and pinned connection.Wherein, pinned connection application is more extensive.
In existing structural design, in tower machine, pin shaft connection structure form is divided into: opening pin, axle end baffle plate formula.Fig. 1 is opening pin, and after bearing pin 3 axle without a head loads the connection part of joint I 1 and joint II 2, two ends are directly pinned fixing with cotter pin 7.Although this Placement can move axially by easy restriction bearing pin, cotter pin is relatively weak, but the rotation of bearing pin cannot be limited, long-time use after, make cotter pin 7 easily wearing and tearing cut off and come off, cause the accident.
Fig. 2 and Fig. 3 is axle end baffle plate formula, and there is the shaft shoulder bearing pin one end, and has the notch coordinated with baffle plate 3-1; When bearing pin 3 without a head loads company headquarters position, axle end baffle plate 3-1 snaps in bearing pin notch, with bolt 3-2, axle end baffle plate 3-1 and connection part is fixed.Fix although this Placement effectively can carry out axle head to bearing pin 3 without a head, when mounted, must consider the relative position of axle end baffle plate 3-1 and bolt hole, efficiency of assembling is lower.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of pin shaft anti-rotation fixing device, cotter pin can be avoided to wear and tear or cut off, improve pinned connection installation efficiency, and can effectively play pin shaft end fixation.
To achieve these goals, the technical solution used in the present invention is: a kind of pin shaft anti-rotation fixing device, and it comprises:
At least one bearing pin without a head, at least two setting sleeves, vertical pin and cotter pins;
Described bearing pin without a head loads joint I and installs setting sleeve with the connection part of joint II, bearing pin two ends without a head, and use vertical pin to be connected with bearing pin without a head by setting sleeve, vertical pin is fixed by packing ring and cotter pin simultaneously.
Described vertical pin quantity is two, is arranged on bearing pin two ends without a head.
Described setting sleeve is rectangle, and its size is mated mutually with end part of pin shaft size without a head.
Compared with existing structural type: the present invention has the following advantages:
1, install quick, simple and direct: pinned connection without a head, dismounting aspect, the easy disposable exact connect ion of vertical pin;
2, safe and reliable: setting sleeve limits bearing pin without a head and rotates, packing ring restriction cotter pin is worn and torn or cuts off, and makes connection safety and reliability.
Accompanying drawing explanation
Fig. 1 is existing design split shed pin structural representation;
Fig. 2 is axle end baffle plate formula structural representation in existing design;
Fig. 3 is side view in Fig. 2;
Fig. 4 is structural representation of the present invention;
Fig. 5 is the side view of Fig. 4.
In figure: 1, joint I, 2, joint II, 3, bearing pin without a head, 3-1, baffle plate, 3-2, bolt, 4, setting sleeve, 5, vertical pin, 6, packing ring, 7, cotter pin.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Wherein, the present invention is with accompanying drawing 4 for benchmark, and left and right, upper and lower, the center of accompanying drawing 4, end are left and right, upper and lower, center of the present invention, end.It should be noted that: unless specifically stated otherwise, otherwise positioned opposite, numerical value of the parts of setting forth in the present embodiment etc. is not limited to scope of the present invention.
As shown in Fig. 4 to Fig. 5, a kind of pin shaft anti-rotation fixing device, it comprises:
At least one bearing pin without a head 3, at least two setting sleeves 4, vertical pin 5 and cotter pins 7;
Described bearing pin without a head 3 loads the connection part of joint I 1 and joint II 2, setting sleeve 4 is installed at bearing pin without a head 3 two ends, vertical pin 5 is used to be connected with bearing pin 3 without a head by setting sleeve 4, vertical pin 5 is fixed by packing ring 6 and cotter pin 7 simultaneously, efficiently solves bearing pin 3 axial-rotation problem without a head.
Wherein, described vertical pin 5 quantity is two, is arranged on bearing pin 3 two ends without a head.
Wherein, described setting sleeve 4 is rectangle, and its size is mated mutually with bearing pin 3 end without a head size.
Compared with existing structural type: the present invention has the following advantages:
1, install quick, simple and direct: bearing pin 3 without a head connects, dismounting aspect, the easy disposable exact connect ion of vertical pin 5;
2, safe and reliable: setting sleeve 4 limits bearing pin 3 without a head and rotates, and packing ring 6 limits the wearing and tearing of cotter pin 7 or cuts off, and makes connection safety and reliability.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
