Abstract
The utility model discloses a dumper body with a back door locking and buffer device. The dumper body comprises a dumber case, a back door and the back door locking and buffer device. Wheels are arranged at the bottom of the dumper case, the back door is in pivot joint to the dumper case, and the rear door locking and buffer device is arranged between the bottom of the dumper case and the back door. According to the dumper body with the back door locking and buffer device, when a dumper runs with materials loaded, the materials produce impulse loads to the back door, the back door locking and buffer device absorbs impact force and consumes the impact force away, a chain is protected, the situation that the chain is pulled apart under the action of instantaneous impact force is avoided, and reliability and safety of the rear door locking and buffer device are improved.
Description
[technical field]
The utility model relates to a kind of composition structure of dumping car, is specifically related to a kind of tipping body with back door lock locking buffering device, belongs to the dumping car technical field.
[background technology]
The operation of travelling under the severe road conditions in mining area when engineering truck, be difficult to avoid material impacting Rear Door in envelope fully, back door lock often occurs and strain at the phenomenon that the bar chain bar is pulled off, and situation occurs to cause that material scatters etc.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved tipping body with back door lock locking buffering device that has, to overcome described defect of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model be to provide a kind of simple in structure, result of use good and the safe and reliable tipping body with back door lock locking buffering device.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of tipping body with back door lock locking buffering device, and it comprises dumper skip, back door and back door lock locking buffering device; Wherein, the bottom of described dumper skip is provided with wheel; On described back door pivot joint dumper skip; Described back door lock locking buffering device is arranged between dumper skip bottom and back door.
Tipping body with back door lock locking buffering device of the present utility model further is set to: described back door lock locking buffering device comprises latch hook support, latch hook, chain, Connection Block, adjusting bolt and setting nut; Wherein, described latch hook is articulated on the latch hook support by the first bearing pin; Described chain one end is articulated on latch hook by the second bearing pin, and the other end is connected on adjusting bolt; Described adjusting bolt is installed on Connection Block by setting nut; Be arranged with buffering apron and packing ring on described adjusting bolt; Described setting nut, packing ring, buffering apron and Connection Block be butt successively.
Tipping body with back door lock locking buffering device of the present utility model further is set to: described buffering apron is served as reasons and is had the buffering apron that elastomeric material processes, and its outside dimension is Φ 100mm, and inner cavity size is Φ 35mm.
Tipping body with back door lock locking buffering device of the present utility model also is set to: described latch hook support is fixed in the bottom of dumper skip; Described Connection Block is articulated in the bottom of dumper skip.
Compared with prior art; the utlity model has following beneficial effect: the tipping body with back door lock locking buffering device of the present utility model is under vehicle loading material travel situations; material produces impact load to back door; this back door lock locking buffering device absorbs impulsive force consume and dissipates; chain is played a protective role; be unlikely under the effect of instant impact, chain is broken, strengthen reliability and the safety of the tight latch mechanism in back door.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the tipping body with back door lock locking buffering device of the present utility model.
Fig. 2 is the structural representation of the back door lock locking buffering device in Fig. 1.
[specific embodiment]
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of tipping body with back door lock locking buffering device, and it is comprised of several parts such as dumper skip 1, back door 2 and back door lock locking buffering devices 3.
Wherein, the bottom of described dumper skip 1 is provided with wheel 4.On the 2 pivot joint dumper skips 1 of described back door.Described back door lock locking buffering device 3 is arranged between dumper skip 1 bottom and back door 2.
Described back door lock locking buffering device 3 is comprised of several parts such as latch hook support 31, latch hook 32, chain 33, Connection Block 34, adjusting bolt 35 and setting nuts 36.Wherein, described latch hook support 31 is fixed in the bottom of dumper skip 1, and a side at close back door 28.Described latch hook 32 is articulated on latch hook support 31 by the first bearing pin 39, and it locks described back door 2.Described chain 33 1 ends are articulated on latch hook 32 by the second bearing pin 38, and the other end is connected on adjusting bolt 35.
Described adjusting bolt 35 is installed on Connection Block 34 by setting nut 36.Be arranged with buffering apron 311 and packing ring 312 on described adjusting bolt 35.Described setting nut 36, packing ring 312, buffering apron 311 and Connection Block 34 be butt successively.Described buffering apron 311 is served as reasons and is had the buffering apron 311 that elastomeric material processes, and its outside dimension is Φ 100mm, and inner cavity size is Φ 35mm.
In loaded material Vehicle Driving Cycle situation, material produces impact load to back door 2, when impulsive force is greater than the tightening force of chain 33, produce compressive deformation by buffering apron 311 with extruding, transient absorption part impulsive force, alleviate the application force that 33 moments of chain break, effectively improved the shock resistance of chain 33, played safety and the reliability of back door 2 lockings.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making within all spirit in this creation and principle, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation.
