Detailed Description
The invention makes the loading and unloading of goods on and off the plane more convenient. The hydraulic lifting device enables the platform to be lifted and fixed on the wheels in a manner different from the previous platform. Because four hydraulic lifting device are independent respectively so can adjust the inclination of platform through the height of adjusting side wheel, rear wheel and make cargo transport more convenient.
The invention is further described below with reference to the figures and examples.
Referring to fig. 1, the device comprises a platform 1, side wheels 2 and rear wheels 3, wherein the side wheels 2 and the rear wheels 3 comprise rear wheel L-shaped mounting seats 4, inner and outer sleeves 5, hand pumps 6, wheels 7, an oil tank 8, a hydraulic cylinder 9, side wheel mounting seats 10, handles 11, throttle valves 12 and a supporting plate 13.
The corresponding mounting position of the side of the platform is symmetrically provided with the side wheels 2 through two quick-release pins, and the corresponding position of the rear part of the platform is symmetrically provided with the rear wheel 3 through a screw and a quick-release pin.
Referring to fig. 3, the side wheels are connected together by two wheels 7 through bearings, and the inner sleeve and the outer sleeve are welded at the middle positions of the bearings. The lower end of the hydraulic cylinder 9 is connected to the inner sleeve and the outer sleeve through bolts, and the upper end of the hydraulic cylinder 9 is connected to the side wheel mounting seat through bolts. The side wheel mounting 10 is welded to the outer sleeves of the inner and outer sleeves 5. The support plate 13 is welded to the outer sleeve of the inner and outer sleeves 5 to keep the support plate 13 parallel to the side of the platform. The hand pump 6 is mounted on the outside of the support plate 13 by four bolts. The oil tank 8 is mounted on the inside of the support plate 13 by two bolts. The handle 11 is directly inserted into the handle mounting hole of the hand pump 6. The throttle valve 12, the oil tank 8, the hydraulic cylinder (9) and the hand pump 6 are connected together through hydraulic oil pipes.
Referring to fig. 2, the rear wheels are connected together by two wheels 7 through bearings, and the inner and outer sleeves are welded at the middle positions of the bearings. The lower end of the hydraulic cylinder 9 is connected to the inner sleeve and the outer sleeve through bolts, and the upper end of the hydraulic cylinder 9 is connected to the side wheel mounting seat through bolts. The rear wheel mounting seat 4 is welded with the outer sleeves of the inner and outer sleeves 5. The support plate 13 is welded to the outer sleeve of the inner and outer sleeves 5 to keep the support plate 13 parallel to the side of the platform. The hand pump 6 is mounted on the outside of the support plate 13 by four bolts. The oil tank 8 is mounted on the inside of the support plate 13 by two bolts. The handle 11 is directly inserted into the handle mounting hole of the hand pump 6. The throttle valve 12, the oil tank 8, the hydraulic cylinder 9 and the hand pump 6 are connected together through hydraulic oil pipes.
The size of the platform can be changed according to the requirement, and the side wheels and the rear wheels provide lifting power and walking capability for the platform. The hand pump converts mechanical energy into hydraulic oil potential energy. Mechanical energy is provided to the hand pump by shaking the handle. The hydraulic cylinder converts the hydraulic oil potential energy into mechanical energy to lift the platform. The oil tank provides sufficient hydraulic oil for the whole system. The throttle valve controls the direction of the oil path and the oil return rate. The inner sleeve and the outer sleeve assist the hydraulic cylinder to lift the platform to prevent the eccentric force borne by the hydraulic cylinder from being too large and breaking a hydraulic rod of the hydraulic cylinder.
When in use, the two side wheels and the two rear wheels are firstly installed according to the figure 1. The rear wheel is connected with the platform through an L-shaped mounting seat, and the side wheel is connected with the platform through a side wheel mounting seat. The handles are the places directly held by the hands of people, and the platform can be gently lifted by simultaneously shaking (the joint flow valve is firstly shaken before the handles are shaken). The inclination angle of the platform can be adjusted by controlling the height difference between the side wheels and the rear wheels. When the platform descends, the descending speed of the platform is controlled by adjusting a knob of the throttle valve.
To sum up, the platform is connected with four hydraulic lifting device through reserving the interface, provides power through the hand pump for hydraulic pressure and makes the platform go up and down, controls the inclination of the lift height control platform of front and back wheel. And controlling a throttle valve to enable the goods platform to descend and return to the original position. The traveling direction of the cargo bed is controlled by controlling the rear wheels in the traveling process of the platform. The platform can be replaced as required.
