[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a simple lifting trolley, including a trolley 1, a support rod 2 is fixedly connected to the surface of the trolley 1, and a through hole is reserved on the surface of the support rod 2, a first steel pipe 8 is fixedly connected through the through hole on the surface of the support rod 2, a large boom 3 is rotatably connected to the surface of the first steel pipe 8, a second steel pipe 9 is fixedly connected to the surface of the large boom 3 near the end, and a counterweight 7 is sleeved on the surface of the second steel pipe 9, a small boom 4 is fixedly connected to the surface of the small boom 4, a winch structure 5 is fixedly connected to the surface of the small boom 4, the winch structure 5 is fixedly connected to a hook 12 through a steel wire rope, a pulley 6 is fixedly connected to the end of the small boom 4, the steel wire rope on the surface of the winch structure 5 is slidably connected to the surface of the pulley 6, and a universal wheel 13 is fixedly connected to the bottom of the trolley 1.

[0019] In a preferred embodiment, the number of counterweights 7 can be increased or decreased according to the weight of the hoisted object, and then the first steel pipe 8 is welded to the support rod 2 through the reserved through hole, and the large boom 3 can rotate around the first steel pipe 8. The small boom 4 is driven by the large boom 3, and then the winch structure 5 is rotated to drive the wire rope to lift the hook 12, so that the hook 12 can assemble and lift the pipes that need to be hoisted. This design has the advantages of simple structure and strong operability, which can reduce labor intensity and improve work efficiency. It also reduces production costs and shortens the production cycle of equipment. It can be used for the assembly of pressure vessel components and the transportation of relatively heavy components.

[0020] In another preferred embodiment, Figure 3 As shown, a groove 10 is provided on the surface of the middle position of the large boom 3, and the large boom 3 is rotatably connected to the surface of the first steel pipe 8 through the groove 10. The groove 10 provided on the surface of the large boom 3 can realize splicing and assembly, thereby improving the overall applicability of the cart 1, making it easy to carry, and allowing the cart 1 to be used for placing tools and other items.

[0021] In another preferred embodiment, Figure 3 As shown, the first steel pipe 8 and the second steel pipe 9 are both solid steel pipes, and the groove 10 is an inclined groove. The solid steel pipe can effectively improve the strength and avoid bending.

The length of the first steel pipe 8 is greater than the width of the two support rods 2, so that both ends of the first steel pipe 8 extend out of the support rods 2, which is convenient for the staff to use. The self-locking winch can assist the staff in lifting by holding the steel pipe to rotate the winch structure 5, and avoid the situation of reversing before locking.

[0024] In another preferred embodiment, Figure 1As shown, a push rod 11 is fixedly connected to the surface of the cart 1, and the cart 1 is assembled by welding angle steel and steel plate. The push rod 11 can facilitate the staff to operate the cart 1. The steel cart 1 can ensure the strength of the cart 1, and the material is easy to obtain and the cost is low. At the same time, it can also ensure the lifting strength and avoid deformation and damage.
