Abstract
The utility model discloses a caterpillar track hasp locking part. A upper locking part sheet (1) and a lower locking part sheet (2) are fixed into a whole through a middle locking bolt (4) which penetrates from top to bottom. The upper locking part sheet (1) and a lower locking part sheet (2) are fixed into a whole through four fixing bolts which penetrate through a track shoe (7). On the premise that the structural strength of the original component is not influenced, two half hasp locking parts are firstly fixed through an added inside hexagonal bolt, thereby facilitating the following installment. The caterpillar track hasp locking part structure can be finished by one worker and is time-saving, energy-saving and high in working efficiency. The caterpillar track hasp locking part can prevent the bolts which are used for tightly fixing the track shoe from being loose. The phenomena of reducing of contact area of tooth portion and breaking of hang teeth caused by looseness of the bolts are avoided. Service life of the locking joint is indirectly prolonged.
Description
Technical field
The present invention relates to the improvement of crawler belt hasp locking joint structure, more particularly, relate to the structural development that convenient locking joint is installed.
Background technology
Under the prior art, what crawler belt hasp locking joint generally adopted is, after the combination of hasp locking nodal plate two halves, connect shared same Bolt Connection with caterpillar block, specifically as shown in Figure 1, comprise locking nodal plate 1 and lower locking nodal plate 2, and the bolt 3 that caterpillar block 7 is connected to upper and lower locking nodal plate.The problem of this connecting mode is, must two people cooperate and to install caterpillar block and hasp joint during installation, labour intensity is large, inefficiency, sometimes also because bolt in use, tooth section area of contact is reduced, cause the serious consequence of broken teeth, have a strong impact on the service life of crawler belt.
Concrete installation steps are:
1, first the locking of two halves hasp is saved the compression that hangs together, pins.
2, four screws on the caterpillar block are alignd with four holes on the locking joint, four bolts are screwed on, twist the power size requirements by bolt and tighten.
Above step must two people partners can be finished when mounted, because every track rail assembly has more than 1000 kilogram at least, because hasp locking joint two halves are the two ends that are contained in advance respectively the same track rail assembly, when two ends were hung together installation, because the tension force effect, a people must pin the locking joint, another person caterpillar block to upper, hold-down bolt again, working strength is larger, and efficient is lower.
Summary of the invention
The present invention aims to provide a kind of crawler belt hasp locking joint installation method that makes things convenient for, and improves installation effectiveness and service life,
In order to achieve the above object, the invention provides a kind of crawler belt hasp locking joint, upper locking nodal plate and lower locking nodal plate are fixed as one by the middle part lock(ing) bolt that wears from top to bottom; 4 bolt of rear end plates that wear caterpillar block are fixed as one described upper locking nodal plate and described lower locking nodal plate.
The present invention links together two halves hasp locking joint in advance by increasing in advance bolted version (also can select the connecting pin structure).Thereby realized following beneficial effect:
1, under the prerequisite of the structural strength that does not affect former assembly, with increasing a socket bolt, in advance two halves hasp locking joint is fixed first, provide convenience to subsequent installation.
2, this structure can a people be finished installation, and time saving and energy saving, increases work efficiency.
3, this structure can also be prevented bolt loosening of tightening caterpillar block, and what the locking joint can be because of tight fixed bolt is loosening, tooth section area of contact occurs and reduces, and breaks the phenomenon of mentioning, has indirectly improved the service life of locking joint.
Description of drawings
Fig. 1 is the installing condition perspective view of prior art crawler belt hasp locking joint;
Fig. 2 is the installing condition perspective view of crawler belt hasp locking joint of the present invention;
Fig. 3 is the installing condition side-looking decomposition texture scheme drawing of crawler belt hasp locking joint of the present invention.
The specific embodiment
Crawler belt hasp locking joint installation method of the present invention specifically shown in Fig. 2 and 3, is fixed as one upper locking nodal plate 1 and lower locking nodal plate 2 from top to bottom first by the middle part lock(ing) bolt 4 that wears; Then utilize four bolt of rear end plates 3 that wear caterpillar block 7 that described upper locking nodal plate 1 and described lower locking nodal plate 2 are fixed as one.Among the figure, label 5 is used for the tapped bore that lock(ing) bolt 4 is fixed for being arranged in lower locking nodal plate 2; Label 6 is used for the tapped bore that bolt of rear end plate 3 is fixed for being arranged in lower locking nodal plate 2.
Under the optimal way, lock(ing) bolt 4 installs a M12 socket bolt additional in the middle of being positioned at hasp locking joint two screws 6.Concrete installation steps are:
1, first two halves hasp locking joint is hung together, with a M12 bolt two halves locking joint is screwed in together, at this moment two halves locking joint is just synthetic as a whole, brings convenience to follow-up work.
2, four screws on the caterpillar block are aimed at four screws on the locking joint, four bolts are loaded onto, screwde on request, inspection, installation.
The people that more than works just can finish, and has greatly improved work efficiency, has reduced simultaneously labour intensity.Because the M12 bolt becomes as a whole to two halfbodies, avoided in the use procedure, since the loosening broken teeth phenomenon that causes of tightening caterpillar block bolt, the service life of greatly having improved product.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
