One end of the chain is connected and fixed to the frame chain seat through a connecting bolt and a locking nut, and the other end is fixedly connected to the platform chain seat on the side of the platform frame assembly.

[0007] Furthermore, ramps and extension plates are respectively installed at both ends of the platform frame assembly, and the ramps, extension plates and platform frame assembly are all equipped with lifting rings, which are connected by iron chains, and chain spring buckles are also installed on the iron chains. When the pallet cargo enters the center position of the platform frame, the ramp is folded, and the chain spring buckle is used to connect the lifting ring on the ramp and the nearest iron chain. At this time, the ramp is in an upright state and fixed by the iron chain, which can play a role in blocking the cargo. The extension plate is equipped with an extension plate support rod with adjustable length on the frame assembly, and a support wheel is installed on the top of the extension plate support rod to support the extension plate.

[0008] There is a switch on the electrical box to control the lifting of the cylinder assembly. The power switch and display, lifting control button and emergency stop switch are installed on the electrical box. A pump station is installed inside to provide power. The power supply adopts V AC. There is an extended control line outside the electrical box to connect the driving switch to facilitate operation on the platform frame. There is an oil pipe connected to one end of the three-way joint on the valve block of the pump station. The other two ends of the three-way joint are connected to the bottom of the two cylinder groups through oil pipes. An explosion-proof valve is installed at the bottom of the cylinder group. When the oil pipe bursts, it can instantly ensure that the platform frame will not fall, thereby effectively protecting the safety of personnel and goods.

[0009] The beneficial effects of the utility model are: 1. The platform vehicle is flexible to operate, convenient to transfer goods to a site, and has a strong load-bearing capacity. 2. The platform vehicle has a simple structure, low production cost, and is suitable for vigorous promotion. BRIEF DESCRIPTION OF THE DRAWINGS

Two straight wheels 4 and two universal wheels 5 are respectively installed at the front and rear of the bottom of the frame assembly 1. Each universal wheel 5 is equipped with an adjustable foot cup group 6. The adjustable foot cup group 6 is provided with a foot screw 7 and a foot cup 8 connected to the foot screw 7. A polyurethane foot pad is fixed at the bottom of the foot cup, which can increase the friction with the ground when in contact with the ground, and can increase the parking stability of the whole vehicle. The cylinder assembly 3 and C-shaped columns 11 are installed side by side on both sides of the frame assembly 1. The cylinder assembly 3 is provided with a cylinder support 13 fixedly installed on the frame assembly 1. The platform frame assembly 2 is installed in the frame assembly 1, and the electrical box 20 is also installed on the outside of the frame assembly 1.

[0014] Two rollers 10 with centers on the same vertical line are installed on both sides of the platform frame assembly 2. The rollers 10 are installed in the C-shaped column 11. The outer diameter of the rollers is slightly smaller than the inner size of the C-shaped column, so that the rollers can rotate freely up and down in the C-shaped column with little shaking. Side rollers 12 are also installed on both sides of the platform frame assembly 2. The side rollers 12 are close to the C-shaped column 11, and together with the other four rollers 10, they limit the front and back, left and right movement directions of the platform frame, and the platform frame can only be lifted and lowered by the rotation of the rollers.

[0015] The upper end of the cylinder body of the cylinder assembly 3 is connected and fixed to the frame chain seat 15 through the cylinder clamp 14, the top of the lifting rod of the cylinder assembly 3 extends into the sprocket seat 17 and is fastened with screws, the sprocket 16 is installed in the sprocket seat 17, and the chain 18 is installed in the groove of the sprocket 16, one end of the chain 18 is connected and fixed to the frame chain seat 15 through a connecting bolt 19 and a locking nut, and the other end is fixedly connected to the platform chain seat on the side of the platform frame assembly 2.

[0016] The platform frame assembly 2 is provided with a ramp plate 21 and an extension plate 24 at both ends of the platform frame assembly 2. The ramp plate 21, the extension plate 24 and the platform frame assembly 2 are all provided with lifting rings 23. The lifting rings 23 are connected by iron chains 22. The iron chains 22 are also provided with chain spring buckles 25. When the pallet cargo enters the center of the platform frame, the ramp plate is retracted, and the chain spring buckle 25 is used to connect the lifting ring on the ramp plate and the nearest iron chain. At this time, the ramp plate is in an upright state and fixed by the iron chain, which can play a role in blocking the cargo. The extension plate 24 is provided with an extension plate support rod 26 with adjustable length on the frame assembly 1. The top of the extension plate support rod 26 is provided with a support wheel 27 for supporting the extension plate 24.
