Description

Anti-rolling out pinch roller device for unloading machine

The technical field is as follows:

the utility model relates to the technical field of car unloaders, in particular to an anti-rolling pinch roller device for a car unloader.

Background art:

the unloading machine is mainly used for unloading large transport vehicles, and two unloading modes are back-overturning unloading and side-overturning unloading, wherein the back-overturning unloading is most widely applied. The principle of backward turning and discharging is that a transport vehicle is driven onto a discharging platform, then the discharging platform is lifted by a hydraulic system to be turned backward, and then materials on the transport vehicle are discharged. The unloading machine has the advantages of time saving, labor saving, high efficiency, low cost and the like, and is widely used for automatically unloading bulk materials such as ores, grains, feeds, grease and other materials.

Although the unloading machine has many advantages, there are some deep technical problems in practical use, for example, the existing unloading machine is limited mainly by the wheel stopper in the whole unloading process, and the unloading platform can completely meet the structural requirements when in a horizontal position or in a small rotation angle, but as the rotation angle of the unloading platform is continuously increased, the structural stability of the whole vehicle and the risk of the transport vehicle rolling out of the wheel stopper (caused by the reduction of vertical component force) are increased, especially when the materials are intensively unloaded from the carriage, the transport vehicle is easy to jump, which further increases the risk of the transport vehicle rolling out of the wheel stopper. Therefore, there is a need for an improved unloader that prevents the wheels of a transport vehicle from disengaging the restraint of the chock.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

The utility model has the following contents:

the utility model aims to solve the problems in the prior art and provides the anti-rolling pinch roller device for the unloader, which has the advantages of reasonable structural design, good pinch roller effect, effective prevention of rolling out of wheels and the like.

The utility model adopts the following technical scheme to realize the purpose:

the anti-rolling-out pinch roller device is used for the unloading machine, and unloading platform bilateral symmetry is equipped with the anti-rolling-out pinch roller device, the anti-rolling-out pinch roller device is including setting up hydro-cylinder support and the lever support on the unloading platform, it has the pneumatic cylinder to articulate on the hydro-cylinder support, it has the lever to articulate on the lever support, the lever front end is equipped with the clamp plate that acts on the rear wheel, the lever rear end is equipped with articulated seat, the piston rod and the articulated seat of articulated connection of pneumatic cylinder.

The lever is T-shaped.

The side wall of the unloading platform is provided with a guide rail, the guide rail is provided with a movable plate, the oil cylinder support and the lever support are installed on the movable plate, and the movable plate is provided with a locking handle.

By adopting the structure, the utility model can bring the following beneficial effects:

the rear wheels are compressed by utilizing a lever principle in combination with a hydraulic cylinder, a pressing plate and a hinged connection, so that the wheels can be effectively prevented from rolling out of the wheel stopper, and the unloading safety is improved; through the design guide rail, can satisfy compressing tightly of not equidimension wheel, the suitability is stronger.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the anti-roll-out pinch roller device of the present invention;

FIG. 2 is a view showing a state of use of the anti-roll-out pinch roller device according to the present invention;

FIG. 3 is a schematic structural view of the anti-roll-out pinch roller device of the present invention including a guide rail;

in the figure, the device comprises an unloading platform 1, an oil cylinder support 2, an oil cylinder support 3, a lever support 4, a hydraulic cylinder 5, a lever 6, a pressing plate 7, a hinged support 8, a guide rail 9, a moving plate 10, a locking handle 11, a rear wheel 12 and a pin shaft.

The specific implementation mode is as follows:

in order to more clearly explain the overall concept of the utility model, the following detailed description is given by way of example in conjunction with the accompanying drawings.
