Description

The chain lock device

Technical field

The present invention relates to a kind of chain lock device according to the characteristic in the preamble of claim 1, it is formed from steel, is used to connect each chain segment that is made up of round steel chain link or flat chain link.

Background technique

Such chain lock device belongs to existing technology in the scope of DE 36 15 201 A1.It has blocking device half one of the U-shaped of two identical formations, and said blocking device half one comprises the hook arc and favours the arm of that extend and the engaging piece that be provided with mutual interlocking in the vertical plane of horizontal center of blocking device half one from the hook arc.Between the inner arm that adjoins each other of each blocking device half one, insert the filling part at the center that is connected with each inner arm.

The characteristic of this chain lock device is the engaging piece on each arm.Convexity and groove that the outer arm of two blocking device half ones and inner arm all extend on the whole thickness that has on the inboard and/or on the outside at each arm, the interlocking each other of the sealed ground of their shapes.

The filling part is made up of hollow cylinder under known case, and this hollow cylinder embeds in each the column part surface on the inboard of the inner arm that is formed in blocking device half one.Two lock balls and a stop pin are used for each blocking device half one of fixed-site, and stop pin can be driven between each lock balls and also can remove from this position once more.

Summary of the invention

From existing technology, the objective of the invention is to the further known chain lock device of exploitation, it can be improved when fatigue limit is higher bear load carrying capacity.

The solution of this purpose is according to the characteristic that the invention reside in claim 1.

Favourable expansion scheme of the present invention is the theme of claim 2 to 21.

The structural form that is different from existing technology, the engaging piece on each arm is made up of the recess that is matched with protuberance protuberance, the other direction of boss shape on the one hand.Therefore do not exist in the engaging piece that extends on the whole thickness of blocking device half one.On each intermeshing side of each inner arm and each outer arm, draw bigger supporting plane thus.Particularly because in this case except that each cross section that keeps the recess, thereby can improve the load carrying capacity of bearing that load carrying capacity also improves whole chain blocking device significantly of bearing of each blocking device half one significantly.What combine with this advantage is to realize high fatigue strength simultaneously.

This new chain lock device is mainly in transporting system, particularly use at the chain drive-belt that is used for underground coal plough drag chain apparatus.Allow such chain lock device not only flatly but also vertically on sprocket wheel, to turn round in known manner according to structure of the present invention.Nominal diameter can be in 1 to 3 to 1 to 5 scope with the inner ration of division of cutting apart.Structure according to DIN 22258-1 is undoubtedly possible in addition.

According to a form of implementation, each protuberance can be arranged on the outside of each inner arm, and each recess can be arranged on the inboard of each outer arm.

Another form of implementation is that each protuberance is arranged on the inboard of each outer arm, and each recess is arranged on the outside of each inner arm.

Irrelevant with form of implementation, each protuberance extends in the vertical central longitudinal plane of each blocking device half one with each recess but basically.Each arm can be provided with two to four protuberances or recess.Particularly respectively three protuberances and with the recess of its coupling be favourable.

If the surface that is positioned at each protuberance and each recess next door in the outside of the inboard of each outer arm and each inner arm constitutes the plane, then realize the further improvement of bearing load carrying capacity to each blocking device half one.

In addition advantageously, each protuberance has rectangular cross section with each recess.Each seamed edge is rounded respectively.But on cross section, also can imagine the oval recess or the geometrical shape of other non-circles.

Be that the length that the horizontal direction towards each arm of each protuberance and each recess is looked is greater than its width along the longitudinal direction of each arm about what the power transmission of the hope between two chain segment also met purpose.

All protuberances can have identical cross section with recess.But what also can imagine is, looks towards the longitudinal direction of each arm, and each protuberance and each recess have the cross section of different size.When so for example three protuberances or recess being set on each arm, protuberance in the middle of each and recess can have bigger cross section than each protuberance and the recess that are positioned at its next door.Be arranged on each protuberance that each protuberance and each recess of the end side of each arm connect each hook arc near also can be again and have small cross section with each recess.

Also can imagine, the degree of depth that the height that the longitudinal direction towards each arm of each protuberance is looked or the longitudinal direction towards each arm of each recess are looked is different.

When each protuberance and each recess when the direction of each hook arc is obliquely installed, then realize the better clasp joint of each protuberance and each recess.

Each side of each protuberance and each recess is 5 ° to 15 °, preferred 10 ° to the tilt angle of the direction of each hook arc in this case.

Also reasonably be that the middle longitudinal region of each arm is thicker than the nominal diameter at each hook arc place within the scope of the invention.

Meet the destination, the separating surface between each outer arm and each inner arm becomes 5 ° to 30 ° angle to extend with respect to the vertical plane of horizontal center.

But more advantageously, the separating surface between each outer arm and each inner arm becomes 10 ° to 20 °, preferred 15 ° angle to extend with respect to the vertical plane of horizontal center.

In order to ensure the exterior contour that does not have protrusion as far as possible of chain lock device, what meet purpose is, looks towards the vertical central longitudinal plane of each blocking device half one, and each outer arm narrows down to its terminal direction.Each outer arm endways side by rounding slightly, thereby guarantee from the transition accurately of profile as far as possible on the surface of the adjacency of each hook arc of lateral of each outer arm.

The supporting of the inboard end chain length that connects with blocking device half one of chain segment improves like this, and promptly the end face spill of the inner arm of each blocking device half one ground is recessed.

What also meet purpose within the scope of the invention especially is that the filling part has mutual opposed cross groove in the face of on the broadside face of each inner arm, each cross groove and the lateral projection mating reaction on the inboard of each inner arm.

But also can imagine a form of implementation, wherein the filling part has the cross groove to the direction intersecting dislocation of each hook arc in the face of on each wide of each inner arm, the lateral projection mating reaction of each cross groove and corresponding dislocation on the inboard of each inner arm.

Two forms of implementation of filling part guarantee, in the operation of chain lock device is used, stop the breaking of each arm of each blocking device half one reliably.

What also meet purpose and the supporting of inboard end chain length that also improve chain segment in blocking device half one thus is that the distolateral spill ground in the face of each hook arc of filling part is recessed.

When the filling part passes through the clamping bolt fixed-site of the slope hole in filling part and each inner arm by means of at least one; Then guarantee the fixed-site of filling part between the inner arm of each blocking device half one, thereby and guarantee operational reliability according to chain lock device of the present invention.Said clamping bolt can for example extend in the transverse plane of the vertical center of chain lock device.

Reasonably be, each inner arm in each side of filling part, constitute the centering recess, extend perpendicular to each slope hole the bottom surface of this centering recess.Owing to only just make each slope hole that is used for clamping bolt, therefore can in these feel relieved recess, accurately locate drill bit so that make each slope hole at the assembled state of each blocking device half one and filling part.
