[0015] The following is combined with Figures 1-5 The embodiments of this utility model will be described in detail below. Example 1

[0016] A grating transport trolley includes a straight frame 1, a double wheel assembly 2 mounted on the frame 1, and a lifting device assembly 3 for lifting grating panels. The double wheel assembly 2 is located in the middle section of the frame 1. The lifting device assembly 3 includes a shackle 4 connected to the front end of the frame and four steel wire rope lifting devices 5 hanging on the shackle 4. The four steel wire rope lifting devices 5 are rectangular hooks that hang on the grating panel 100 and lift the grating panel 100 as the front end of the frame 1 is raised.

[0017] The grating transport trolley described above has a straight frame 1 with two wheel sets 2 mounted in the middle. Four wire rope lifting devices 5 are attached to the shackles 4 connected to the front of the frame 1. When transporting the grating 100, the front of the frame is lowered first, and the four wire rope lifting devices 5 are hooked onto the grating 100 in a rectangular pattern. Then, the rear of the frame 1 is pressed down to raise the front, lifting the grating 100 with the lifting of the front. The frame 1 is then pushed forward to transport the grating to the work position. The rear of the frame 1 is then raised, lowering the front to lower the grating 100. Finally, the wire rope lifting hooks 5 are removed from the grating 100, and the grating 100 is placed flat at the work position. The grating is then lifted using leverage. During operation, only one person is needed to push the trolley, saving time and effort, reducing labor intensity and safety risks, and improving transport efficiency. The structure is simple, and materials can be sourced and assembled on-site, resulting in low cost and high practicality.

[0018] The wire rope lifting device 5 consists of a wire rope 51 and a hook 52 connected to the lower end of the wire rope 51. A lifting lug 6 connected to a shackle 4 is welded to the front end of the frame 1. The upper end of the wire rope 51 is connected to the shackle 4, and the hook 52 is hooked onto the grating plate 100. Four rectangularly distributed hooking positions are selected in the middle of the grating plate 100, and the hooks 52 at the lower ends of the four wire ropes 51 are hooked onto these positions respectively. When the front end of the frame 1 tilts upwards, the four wire ropes 51 are simultaneously straightened, lifting the grating plate 100 into the air.

[0019] The frame 1 includes a crossbar 7, a wheel support frame 8 for mounting the dual wheel assembly 2, and support rods 9 connecting the wheel support frame 8 and the crossbar 7. The wheel support frame 8 is rectangular and parallel to each other below the middle section of the crossbar 7. Each apex of the wheel support frame 8 is connected to the crossbar 7 by a support rod 9. Lifting lugs 6 are welded to the front end of the crossbar 7, and support handles 10 are welded to the rear end of the crossbar 7. The wheel support frame 8 is connected to the crossbar 7 by four support rods 9, supporting the crossbar 7 above the wheel support frame 8 to ensure the stability of the frame structure. The dual wheel assembly 2 is mounted on the wheel support frame 8. Using the dual wheel assembly 2 as a fulcrum, pressing down on the support handle 10 can lift the front end of the crossbar 7, allowing the wire rope lifting device 5 to lift the grating plate 100.

[0020] The wheel support frame 8 is fastened to two opposite sides parallel to the crossbar 7 with U-bolts 11. The double wheel assembly 2 includes an axle 12 passing through the two U-bolts 11 and rotatable wheels 13 mounted at both ends of the axle 12. The axle 12 passes through the two U-bolts 11 on the wheel support frame 8, resulting in a simple assembly structure that facilitates rapid assembly. The crossbar 7, wheel support frame 8, support rod 9, wheels 13, and axle 12 can all be sourced and assembled on-site, resulting in low cost and high practicality. Example 2

[0021] The difference from Embodiment 1 is that the crossbar 7 includes a hollow fixed rod 71 and a movable rod 72 that can move within the fixed rod 71. The support rod 9 is connected between the wheel support frame 8 and the fixed rod 71. The lug 6 is welded to the front end of the fixed rod 71. The support handle 10 is welded to the rear end of the movable rod 72. The front end of the movable rod 72 is inserted into the fixed rod 71 from the rear end of the fixed rod 71. The rear end of the fixed rod 71 is screwed with a tightening screw 73, and the lower end of the tightening screw 73 abuts against the movable rod 72. In this embodiment, the length of the crossbar 7 can be adjusted by the movement of the movable rod 72 in the fixed rod 71. Since different specifications of grating plates have different weights and sizes, in order to make the handling easier, the crossbar 7 is set to an adjustable length structure. When the weight of the grating plate being handled is greater, the length of the crossbar 7 can be increased accordingly, thereby increasing the length of the frame on the rear side of the wheel 12, which can lift the grating plate more easily. In order to prevent the movable rod 72 from moving or coming out of the fixed rod 71 after the length of the crossbar 7 is adjusted, a tightening screw 73 is screwed into the rear end of the fixed rod 71. When the tightening screw 73 is tightened, its lower end abuts against the movable rod 72, restricting the movement of the movable rod 72. When it is necessary to adjust the length of the crossbar 7, the tightening screw 73 is loosened so that the movable rod 72 can move in the fixed rod 71 to adjust the length of the crossbar 7.
