Description
Technical field
The utility model relates to dumping car and manufactures field, is specifically related to a kind of heavy-duty tipper back door chain-type catch gear.
Background technology
Dumping car refers to the vehicle of the unloaded of cargo voluntarily by hydraulic pressure or mechanical lift, because can greatly save dumping time and labour power, shorten the haul-cycle time, enhance productivity, reduce the advantages such as traffic cost and be widely used, but the general colliery in the open of dumping car, steel mill, bulk cargo terminals, large-scale building site, some road conditions such as reclamation are poor, the place operation that operating environment is severe, traditional chain-type catch gear chain in operation is easily out of shape and even ruptures, coupling mechanism force can not adjust, the damaged not easily maintain and replace that ruptures also of chain, a lot of inconvenience is brought to user.
Utility model content
Technical problem to be solved in the utility model is to provide one can regulate coupling mechanism force, can effectively cushion when chain is subject to external force excessive instantaneously, prevent from chain to be pulled out of shape to break, maintain and replace or adjustment chain length heavy-duty tipper back door chain-type catch gear easily especially.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of heavy-duty tipper back door chain-type catch gear, comprise adjusting bolt seat, regulate locking bar assembly, chain, lock hook seat, latch hook, described adjusting bolt seat is fixed on bottom body dump, described lock hook seat fixes the bottom of compartment tail end, described adjustment locking bar assembly comprises nut, large washer, bump rubber, regulate locking bar, described adjustment locking bar one end is thread end, the described adjustment locking bar other end is U-shaped end, overall U-shaped structure, wall is provided with through hole, described nut and large washer, bump rubber is contacted successively on the thread end regulating locking bar, secured adjusted bolt block, described chain one end is connected with the U-shaped end bearing pin of adjustment locking bar, the described chain other end is connected with latch hook bearing pin, described latch hook is connected with lock hook seat.
On such scheme basis preferably, described buffer substrate tablet is made up of elastomeric material.
On such scheme basis preferably, described chain and the process of lock hook seat plating zinc on surface.
The beneficial effect that the utility model compared with prior art has is: the length available being changed screw rod by setting nut, ensures the strong coupling mechanism force between lock hook seat and back door; Accompany large washer and bump rubber between nut and latch hook lower bracket, good damping, buffering effect can be played when latch hook lower bracket is stressed; The adjustment locking bar of U-shaped structure and chain use the pinned connection of bearing pin, pad and spring cotter, and connect simple, intensity is reliable, arbitrarily can change the use length of chain, need also very easily to take off when replacing or maintenance; Zinc-plated process is carried out to chain and lock hook seat surface, can ensure that can not go up rust after they use for a long time rots.
Accompanying drawing explanation
Fig. 1 is the utility model integral structure schematic diagram;
Fig. 2 is the structural representation that the utility model regulates locking bar.
Number in the figure is: 1-adjusting bolt seat, 2-nut, 3-large washer, 4-bump rubber, and 5-regulates locking bar, 5.1-thread end, 5.2-U type end, 6-chain, 7-lock hook seat, 8-latch hook.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Known with reference to Fig. 1 Fig. 2, a kind of heavy-duty tipper back door chain-type catch gear, comprise adjusting bolt seat 1, regulate locking bar assembly, chain 6, lock hook seat 7, latch hook 8, described adjusting bolt seat 1 is fixed on bottom body dump, described lock hook seat 7 fixes the bottom of compartment tail end, described adjustment locking bar assembly comprises nut 2, large washer 3, bump rubber 4, regulate locking bar 5, described adjustment locking bar one end is thread end 5.1, the described adjustment locking bar other end is U-shaped end 5.2, overall U-shaped structure, wall is provided with through hole, described nut 2 and large washer 3, bump rubber 4 is contacted successively on the thread end 5.1 regulating locking bar 5, secured adjusted bolt block 1, described chain one end is connected with regulating U-shaped end 5.2 bearing pin of locking bar 5, described chain 6 other end is connected with latch hook 8 bearing pin, described latch hook 8 is connected with lock hook seat 7.
Further, described bump rubber 4 is made up of elastomeric material.
Further, described chain 6 and lock hook seat 7 do zinc-plated process on surface.
During dumping car roping goods; back door of vehicle is locked by lock hook seat 7 by the chain 6 in extended state; in using; back door often can be subject to the shock extruding of goods; give the load that chain 6 is excessive instantaneously; bump rubber 4 is made up of elastomeric material, at this moment can effective cushion impact forces, prevents chain 6 from being broken suddenly or being out of shape.During use, regulate locking bar 5 to change the coupling mechanism force at latch hook 8 pairs of back doors by effect, bearing pin can through the annular distance of any one section of chain 6.Adjustment regulates the nut 2 on locking bar 5 can change arbitrarily chain 6 can use length, chain 6 and regulate locking bar 5, use bearing pin between lock hook seat 7, the pinned connection of pad and spring cotter, connect simple, chain 6 maintain and replace is also convenient, zinc-plated process is carried out to chain 6 and lock hook seat 7 surface, can ensure that can not go up rust after they use for a long time rots.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
