Abstract
The utility model relates to an automatic pulling device for rear board of a self-dump truck, which uses a steel rope and a dead pulley assembly. Pivoting points (6) are mounted on both sides of the upper end of the two side boards of the self-dump truck, second fixed points (5) are disposed on both side of the upper section of the rear board (7), fixed pulleys (3, 4) are provided on the upper and the lower side boards on both sides on the rear portion of the carriage, and the steel rope passes through the second fixing point (5), gets around the fixed pulleys (3, 4) and is linked to a first fixed point (2) on the bottom beam (8) of the frame. When the carriage is lifted, the rear door automatically opens along with the height increment of the carriage, the impact from the cargo to the rear board is reduced during dumping, the blocking of the cargo is reduced, so that damage to the rear board is reduced, the problems of easiness in dropping, cracking, and deformation of the dumping rear board is solved. Moreover, the structure of self-dumping semitrailer truck is simplified, work of design is reduced, weight is lightened, the production cost is reduced, and the most simple mode with relatively less cost is provided for the improvement of the self-dumping truck.
Description
Technical field
The utility model relates to the dumping car technical field, relates in particular to plate after the formula of turning over certainly of dumping car.
Background technology
At present dumping car generally adopts plate behind the bolt hook-type, there is not exterior power, automatically sagging and open when lifting by dumping car, its opening angle is little, the obstruction goods glides, and is big to the bump of back plate when unloading weight such as stone, thereby makes fragile, the distortion of back plate, can not SELF CL, influence the normal use of car.Development along with technology, though also improve, bonnet winding type synchronous lifting dumping car is arranged, be respectively arranged with the bonnet hoist lifting device on the both sides of the box back of this dumping car, connect by a closed loop steel rope between these two bonnet hoist lifting devices, bonnet is provided with fixed pulley, steel rope promotes bonnet via this fixed pulley and by driving steel rope, though improved the speed of unloading to a certain extent, it need spur steel rope by the power of hydraulic efficiency gear to promote bonnet, its structure more complicated is not easy operation.The automatic pull-up device of back plate is arranged subsequently, solved above-mentioned technical matters, but still have certain productive costs.
Summary of the invention
The utility model provides the automatic pull-up device of plate behind a kind of mechanical type dumping car for solving the problems of the technologies described above, and it can overcome and solve defective and the deficiency that exists in the prior art.
The technical scheme of the utility model technical solution problem: the automatic pull-up device of plate behind a kind of dumping car comprises fixed pulley, attachment point, steel rope, fulcrum etc.It is characterized in that, changed traditional design routine, the back plate is set respectively on the both sides of box back draws high device automatically, back plate utilizes steel rope and assembly pulley, rope one end is connected side plate epimere both sides, back, plate is controlled by steel rope behind the dumping car, and plate is slowly risen by the steel rope pulling after self-discharging carriage is slowly during lifting.
The utility model has utilized steel rope and fixed pulley assembly, the both sides of back plate (7) upper end are installed second attachment point (5) respectively, one end of steel rope (1) is connected on second attachment point (5), fixed pulley (3,4) is installed in rear end, both sides, compartment side plate symmetry up and down, go up symmetry at the bottom girder (8) of vehicle frame both sides first attachment point (2) is installed, steel rope (1) one end is connected second attachment point (5), and the other end is connected first attachment point (2).
The automatic pull-up device of plate behind the described dumping car is characterized in that: by steel rope (1) fixed pulley (3,4) is connected with first attachment point (2), second attachment point (5).
The automatic pull-up device of plate behind the described dumping car is characterized in that: be symmetrically arranged with fulcrum (6) on side plate on the rear end of both sides, compartment, the compartment is connected with back plate (7).
The automatic pull-up device of plate behind the described dumping car is characterized in that: fixed pulley (3,4) is formed assembly pulley.
The automatic pull-up device of plate behind the described dumping car is characterized in that: first attachment point (2) is arranged on the bottom girder (8) of vehicle frame, any point selection that first attachment point (2) can be on vehicle frame bottom girder (8).
The automatic pull-up device of plate behind the described dumping car is characterized in that: the rope that steel rope (1) connects fixed pulley (3,4) places interior.
The automatic pull-up device of plate behind the described dumping car is characterized in that: the rope that steel rope (1) connects fixed pulley (3,4) places the outside, compartment.
When the compartment lifted, steel rope (1) was walked around fixed pulley (3,4) pulling second attachment point (5) and is raised, and is the center with fulcrum (6), will the slowly pull-up of back plate (7).Technique effect of the present utility model is: utilize the utility model, when the compartment from time-out, open automatically with the height of wagon increase at the back door, by the both sides steel rope will the back plate be lifted to parallel with car body, reduced damage to the back plate, solve the problem that plate comes off easily, ftractures, is out of shape behind the dumping car, simplified the structure of self-discharging semitrailer, reduced the design effort amount, alleviated weight, having reduced productive costs, is the transformation of dumping car also, provides mouse less and the easiest pattern.
