Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic flap unloading machines, in particular to a walking type hydraulic flap unloading machine. Background Art

[0002] Hydraulic flap unloaders are mainly used for fast unloading of bulk materials and improving the transportation efficiency of bulk materials. Hydraulic flap unloaders mainly include side-flip hydraulic flap unloaders and rear-flip hydraulic flap unloaders. The truck carrying bulk materials is driven onto the flap, and the flap is driven up by hydraulic transmission to tilt the vehicle body and complete the unloading.

[0003] The Chinese patent with application number CN201921488636.X provides a self-propelled hydraulic flipping device, including a chassis with wheels, a lifting platform hinged at one end on the chassis, and a hydraulic cylinder hinged between the chassis and the lifting platform to drive the free end of the lifting platform to lift or fall; it also includes a rotary motor and a reducer fixed to the chassis, and an energy absorption and anti-collision mechanism for the reducer and the rotary motor is arranged in front of the chassis. By arranging wheels, rotary motors and reducers on the chassis, the overall structure can have a walking function without external power, and the hydraulic cylinder is arranged between the protective beam and the chassis. On the one hand, it is convenient to arrange the hydraulic cylinder and ensure that the lifting platform is not affected by the hydraulic cylinder lifting arm and can be completely dropped. On the other hand, the two settings of the protective beam can also ensure the stability of the lifting platform during the lifting process.

[0004] The wheels of the above-mentioned device do not have a steering function and cannot be adjusted for steering, which makes it inconvenient to accurately adjust the position of the hydraulic flap unloader; when the hydraulic flap unloader is unloading a truck, the hydraulic flap unloader is supported as a whole by support columns, and the chassis of the hydraulic flap unloader cannot contact the ground, resulting in a small unit contact area between the hydraulic flap unloader and the ground, and a large force per unit area of ​​the ground. When unloading, the ground has to bear the entire gravity of the hydraulic flap unloader, the truck and the goods, which can easily damage the ground. At the same time, its supporting stability is reduced, which is far less stable than the contact between the chassis of the hydraulic flap unloader and the ground. Utility Model Content

[0005] The utility model aims to provide a walking hydraulic flap unloader, the wheels of which are provided with a steering mechanism for steering adjustment, so as to facilitate precise adjustment of the position of the hydraulic flap unloader, and the wheels can move up and down. During unloading operations, the chassis of the hydraulic flap unloader contacts the ground, thereby increasing the contact area and stability of the hydraulic flap unloader with the ground.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a walking hydraulic flip-plate unloading machine, including a hydraulic flip-plate unloading machine, a chassis of which is provided with a plurality of wheels and a driving device for driving the wheels to lift and lower; a steering mechanism for adjusting the steering of the wheels is also provided between the wheels and the driving device.

[0007] Preferably, the wheels include two front wheels and two rear wheels, the front wheels are transitionally connected to the drive device via a steering mechanism; and the rear wheels are directly connected to the drive device.

[0008] Preferably, the steering mechanism includes a first seat plate and a connecting shaft rotatably disposed on the first seat plate, one end of the connecting shaft is cooperatively connected to the wheel; the first plate seat and the connecting shaft together form a steering mechanism and are cooperatively connected to the driving device.

[0009] Preferably, the first seat plate is provided with an axial hole for the connecting shaft to pass through, and the upper and lower sides of the first plate seat are respectively provided with axial bearings coaxially arranged with the axial hole, and a limiting portion for axial limiting is provided on the connecting shaft and located on the outer sides of the two axial bearings.

[0010] Preferably, the steering mechanism further includes a swing cylinder for driving the connecting shaft to rotate.

[0011] Preferably, it also includes a driving motor for driving the wheels to rotate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the wheels are provided with a steering mechanism, which can be used for steering adjustment, so as to facilitate the precise adjustment of the position of the hydraulic flap unloading machine.

[0014] 2. The utility model has wheels that can move up and down. During unloading operations, the chassis of the hydraulic flap unloader contacts the ground, increasing the contact area and stability of the hydraulic flap unloader with the ground.
