Abstract
The utility model relates to an automatic mechanical rear-board opening/closing device for a heavy-duty mine self-discharging vehicle, pertains to the transportation field, is characterized in that on a baseboard, a transversal rib is provided, at two sides of the base board, a support is mounted; a lock hook is fixedly mounted on the support; one end of the lock hook is sequentially connected with a rigging-unloading buckle and a tension spring; the tension spring is connected with a helical buckle through a steel rope, the helical buckle is connected with an eye bolt fixed on the rear axle through the steel rope; at back of the two side boards, the support is mounted; the rear cover board is movably connected with the support, and is fit with the side boards and the base board. While improving the loading capacity of the mine self-discharging vehicle, the utility model can achieve automatic opening and closing of the rear cover board, and the mechanism is simple and practical.
Description
One, technical field
The utility model relates to the automatic folding back shroud of heavy mining truck mechanical type device.Belong to transport field.
Two, background technology
The railway carriage of heavy mining truck standard configuration is primarily aimed at the bigger material of ore equidensity and designs, so its rear portion is a unenclosed construction.When loose type materials such as transportation coal, sandstone,,, need increase cover plate to increase volume at aftbody for giving full play to the load carrying behaviour of quarry tipper because of density is littler than ore.Simultaneously, convenient and for satisfying discharging in transportation, when back shroud mechanism should be implemented in discharging self-opening and when transportation the function of auto lock, thereby no longer need get off manual folding or adopt complicated hydraulic pressure closing device of chaufeur.
Three, summary of the invention
The technical matters that the utility model solves is: improve the rate of loading of heavy type mining car and realize the automatic folding of back shroud, need not chaufeur gets off manually opened or avoids adopting complicated hydraulic pressure closing device, simple in structure, easy to operate, prevent the unrestrained of material, thereby reduced pollution environment.
Technical solution:
The utility model base plate is provided with horizontal bar, both sides are equipped with support, latch hook is fixedly mounted on the support, the one end butt rigging shackle successively of latch hook, extension spring, extension spring is connected with a turnbuckle by steel rope, and turnbuckle is connected biside plate rear portion mounting bracket by steel rope with suspension ring nut on being fixed on back axle, back shroud and support flexibly connect, and fit with side plate and base plate.
The effect of the utility model back shroud is to increase the railway carriage volume and prevent that material is unrestrained, and it adopts and arranges the horizontal bar with booster action on the base plate, and both sides are welded with mounting bracket.Back shroud is complied with the support of aftbody form and biside plate upper back, and swivel pin is connected with rotating flexibly, thereby back shroud and biside plate and base plate have been formed the sealing box-structure.
The beneficial effects of the utility model are, when improving the quarry tipper load carrying behaviour, can realize back shroud self-opening and closure, and mechanism is simple and practical.
Four, description of drawings
Fig. 1 is the utility model rear cover plate structure figure;
Fig. 2 is the automatic opening-closing machine composition of the utility model mechanical type;
Five, the specific embodiment
In Fig. 1, back shroud 12 is installed on the support 11 of side plate 10 upper backs with swivel pin 13, guarantee that back shroud 12 is tight with railway carriage side plate 10 and base plate 7 applyings.
In Fig. 2, base plate 7 is provided with horizontal bar 8, both sides are equipped with support 9, latch hook 6 is fixedly mounted on the support 9, the butt rigging shackle 5 successively of one end of latch hook 6, extension spring 4, extension spring 4 is connected with a turnbuckle 2 by steel rope 3, turnbuckle 2 is connected with suspension ring nut 1 on being fixed on back axle by steel rope 3, the lifting railway carriage connects each part in the automatic closing device successively slightly, regulates the length of steel rope 3, make the other end of latch hook 6 be fitted on the back shroud just, the railway carriage that slowly descends then, at this moment extension spring 4 is subjected to the tension elongation, and the tension latch hook compresses the back tailgate.Turn turnbuckle 2 has changed by latch hook the extension spring lengthening and is added in size stressed on the back shroud to desired value.Because the effect of latch hook thrust, back shroud can not reach locking and prevent the purpose that material is unrestrained again because bump base plate phenomenon appears in jolting in the vehicle enforcement.During discharging, lifting along with railway carriage, because steel rope loosens, extension spring length shortens thereupon, latch hook is stressed to be reduced gradually, and latch hook is because self gravitation rotates and the back shroud disengaging, and at this moment back shroud is also opened by the self gravitation effect, material comes down in torrents downwards, thereby has realized the self-opening function.Discharging finishes, and railway carriage descends, and back shroud falls back to earlier on the side plate, and extension spring drives latch hook again back shroud is compressed.
