Abstract
The utility model discloses a lever-type dumper rear boxboard opening device which is characterized by comprising levers installed at two sides of the rear end of a dumper box, wherein the supporting points of the levers are respectively arranged on hinge pins at the upper part of the rear end of the box; the front ends of the lever arms are respectively connected with the auxiliary frame of the dumper through connecting pieces; the rear boxboard is respectively connected with the rear ends of the lever arms through rotary pins arranged at the upper ends of the left and right sides; and the rear boxboard can rotate around the rotary pins relative to the lever arms. The device has the benefits: the rear boxboard has comparatively large open degree and can meet the self-discharging requirements of large-volume goods.
Description
Technical field
The utility model relates to the physical structure on a kind of dumping car, especially a kind of opening device of dumping car rearing-box plate.
Background technology
The rearing-box plate that existing dumping car lifting rearing-box plate opening ways generally all is the dumping car railway carriage rotates under the effect of deadweight around one group of link pin.Under this opening ways, because the upper end of rearing-box plate is connected on the railway carriage all the time, make the opening degree of rearing-box plate be subjected to certain restriction, aperture is less, damages the railway carriage rearing-box plate when measurement of cargo big (as ore etc.) easily.
The utility model content
In order to overcome the rearing-box plate aperture problem of smaller of dumping car railway carriage in the prior art, the purpose of this utility model is to provide a kind of lever rearing-box plate opening device that can increase the rearing-box plate aperture.
The technical scheme that the utility model adopted is: a lever is respectively installed on the top in the left and right sides, dumping car casing rear end, the fulcrum of described lever is provided in a side of the bearing pin on box back top respectively, the front end of throw of lever links to each other by the subframe of attaching parts and dumping car respectively, described rearing-box plate is connected with the rear end of throw of lever by being located at shipping and reselling on another market of left and right sides upper end respectively, and the rearing-box plate pin that can rotate rotates relative to throw of lever.
When dumping car during in lifting, the front end of throw of lever is owing to there is the attaching parts restriction, and the distance of the relative vehicle frame of front end can not change, and makes the rear end upward movement of throw of lever, drives rearing-box plate and upwardly opens.
Further, the throw of lever inhibiting device can also be set on rearing-box plate, described inhibiting device is located at the rearing-box plate both sides respectively, heads on the rear end of throw of lever.After inhibiting device has been installed, when the rear end of throw of lever makes progress lifting,, therefore can further increase the aperture of rearing-box plate because throw of lever withstands inhibiting device rearing-box plate is lifted.
Those skilled in the art will be understood that the attaching parts that connects throw of lever front end and vehicle frame generally can be a connecting rod, and the two ends of connecting rod are hinged with the front end and the vehicle frame of throw of lever respectively.In other embodiment of the present utility model, attaching parts can also be an iron chains, and the effect that it can play restriction throw of lever front position does not influence the rotation within the specific limits of throw of lever front end again.
Technique effect of the present utility model is: the rearing-box plate aperture is bigger, can satisfy the self-unloading requirement of bulkload.

The specific embodiment
Below further specify the utility model by an embodiment.
As shown in Figure 1, lever dumping car rearing-box plate opening device comprises the lever that is installed in railway carriage 8 rear ends two upper lateral parts, and the fulcrum of described lever is provided in a side of the bearing pin 3 of railway carriage 8 rear upper end, and throw of lever 2 can rotate around bearing pin 3.The front end of throw of lever 2 links to each other with subframe 9 by iron chains 1.Rearing-box plate 10 4 is connected with the rear end of throw of lever 2 by shipping and reselling on another market of upper end, its both sides, and rearing-box plate 10 pin 4 that can rotate rotates relative to throw of lever 2.On rearing-box plate 10, also be provided with inhibiting device 5.As shown in Figure 2, inhibiting device 5 heads on the rear end of throw of lever 2, plays the effect in relative rotation between restriction rearing-box plate 10 and the throw of lever 2.Also be provided with latching device on the rearing-box plate 10, comprise the locking pin 7 that is located at rearing-box plate 10 sides and be located on the dumper skip 8 and locking pin 7 cooresponding latchs 6.Latch 6 is welded on the casing, locking pin 7 is welded on the rearing-box plate 10, when railway carriage 8 descends, rearing-box plate 10 by gravitys can descend along with the decline of throw of lever 2 rear ends, locking pin 7 just in time drops in the breach of latch 6 when rearing-box plate 10 falls, rearing-box plate 10 is locked like this, the general paired setting of latching device.
When the railway carriage 8 of dumping car during in lifting, because the front end of throw of lever 2 is subjected to pining down of iron chains 1, make the rear end of throw of lever 2 drive rearing-box plate 10 upward movements, while throw of lever 2 withstands inhibiting device 5 lifts rearing-box plate 10, thereby open rearing-box plate 10, this moment, the opening of rearing-box plate 10 was bigger, the bigger goods of convenient unloading volume.State after rearing-box plate 10 is opened as shown in Figure 3.
