Detailed Embodiment

[0025] The detailed embodiment of the present utility model will be described below with reference to the drawings.

[0026] As Figure 1 , Figure 2 shown, the power-free steel member transporting tool of the present utility model includes a side frame 1, a top frame 2, a front lifting mechanism 3, a rear lifting mechanism 4, a front support 5, a rear support 6, wheels 8 and a handle 7.

[0027] Among them, there are two side frames 1 in total, and the two side frames 1 are located on the left and right sides. The top frame 2 is located at the top of the two side frames 1 and connects the two side frames 1 into an integral structure. The two side frames 1 and the top frame 2 form an inverted U-shaped structure. Wheels 8 are provided at the bottom of the side frames 1. A front lifting mechanism 3 is provided at the front of the top frame 2. A rear lifting mechanism 4 is provided at the rear of the top frame 2. A front support 5 is provided in front of each side frame 1. A rear support 6 is provided behind each side frame 1. The handle 7 is provided in front of or behind the side frame 1, or handles 7 are provided both in front of and behind the side frame 1.

[0028] The top frame 2 is specifically divided into two layers, including a lower layer frame 2-1 and an upper layer frame 2-2. Among them, the lower layer frame 2-1 is a rectangular frame structure, including a number of cross bars and a number of longitudinal bars, and its length is the same as that of the side frame 1. The lower layer frame 2-1 connects the middle or upper middle parts of the two side frames 1. The upper layer frame 2-2 is also a rectangular frame structure, including a number of cross bars and a number of longitudinal bars. The upper layer frame 2-2 connects the tops of the two side frames 1. The length of the upper layer frame 2-2 is greater than that of the side frame 1, and both ends of the upper layer frame 2-2 extend forward and backward. Diagonal braces 2-3 are provided between the edges of the extending ends of the upper layer frame 2-2 and the side edges of the side frame 1. The front lifting mechanism 3 and the rear lifting mechanism 4 are respectively provided in the middle of the front and rear ends of the upper layer frame 2-2. A number of inclined connecting rods are provided between the upper layer frame 2-2 and the lower layer frame 2-1 to ensure the overall structural strength of the top frame 2 and the entire device.

[0029] To further ensure the structural strength and lifting stability, a number of diagonal braces 2-4 are respectively provided between the connection points of the front lifting mechanism 3 and the upper layer frame 2-2 and the lower layer frame 2-1, and between the connection points of the rear lifting mechanism 4 and the upper layer frame 2-2 and the lower layer frame 2-1. The upper ends of the diagonal braces 2-4 are gathered and connected to the ends of the upper layer frame 2-2, and the lower ends are radially connected to the lower layer frame 2-1. The lifting mechanism is supported by multiple diagonal braces 2-4 at the same time, and the gravity during lifting is evenly transmitted to the lower layer frame 2-1, thereby preventing deformation and damage of the top frame 2.

[0030] Among them, both the front lifting mechanism 3 and the rear lifting mechanism 4 include connecting ear plates 9, lifting rings 10 provided on the connecting ear plates 9, and chain hoists 11 hung on the lifting rings 10. The connecting ear plates 9 are welded and fixed to the upper layer frame 2-2. Since the present utility model is a non-powered steel member transportation tool and does not have a power system and a power source, an electric hoist is not applicable here.

[0031] Both the front support 5 and the rear support 6 include support legs 12 and connecting frames 13. The support legs 12 are vertically arranged, and the support legs 12 are connected to the side frame 1 through the connecting frames 13. The connecting member includes two parallel cross bars. One end of each of the two cross bars is connected to the side frame 1, and the other end of the two cross bars is connected to the support legs 12. An inclined bar is provided between the two cross bars. Among them, the cross bar at the upper part of the connecting frame 13 extends outward to form a handle 7. The handle 7 can be provided on the front side or the rear side of the device, or on both the front and rear sides.

[0032] The lower ends of the support legs 12 of the front support 5 and the support legs 12 of the rear support 6 are slightly higher than the lower ends of the wheels 8. In this way, when the side frame 1 tilts slightly around the wheels 8, the support legs 12 can contact the ground.

[0033] The present utility model also discloses a method for transporting steel components without power, including the following steps.

[0034] a. Arrange a power-free steel component transporting tool at the steel structure construction site. The power-free steel component transporting tool includes two left and right side frames 1. The tops of the two side frames 1 are connected by a top frame 2. The two side frames 1 and the top frame 2 form an inverted U-shaped structure. Wheels 8 are provided at the bottom of the side frames 1. A front lifting mechanism 3 is provided at the front part of the top frame 2. A rear lifting mechanism 4 is provided at the rear part of the top frame 2. A front support 5 is provided in front of the side frame 1. A rear support 6 is provided behind the side frame 1. A handle 7 is provided in front of and / or behind the side frame 1.

[0035] b. Move the power-free steel component transporting tool to the steel component to be transported, so that the power-free steel component transporting tool is located at one end of the length direction of the steel component. The steel component is located between the two side plates. Push the power-free steel component transporting tool along the length direction of the steel component until the top frame 2 is directly above the steel component.

[0036] c. Lower the front lifting mechanism 3 and the rear lifting mechanism 4 respectively, and connect the front lifting mechanism 3 and the rear lifting mechanism 4 to the steel component respectively.

[0037] d. After the front lifting mechanism 3 and the rear lifting mechanism 4 are firmly connected to the steel component, adjust the heights of the front lifting mechanism 3 and the rear lifting mechanism 4 to lift the steel component off the ground.

[0038] e. Manually push the power-free steel component transporting tool to move the steel component to a predetermined position, lower the front lifting mechanism 3 and the rear lifting mechanism 4 respectively, and lower the steel component to the ground.

[0039] f. Disconnect the front lifting mechanism 3 and the rear lifting mechanism 4 from the steel component respectively to complete the transportation of the steel component at the construction site.

[0040] Among them, in step b, when moving the unpowered steel member transfer tool above the steel member, the center of the steel member in the length direction is made to basically coincide with the center of the unpowered steel member transfer tool in the length direction.

[0041] When parking the unpowered steel member transfer tool, the unpowered steel member transfer tool is tilted forward or backward so that the front support 5 or the rear support 6 contacts the ground.

[0042] The unpowered steel member transfer tool of the present utility model is applicable to the steel structure construction site with a narrow site, a large number of members, and where powered transportation tools cannot move freely. Due to its small and flexible structure and large load capacity, it can quickly transfer steel members, and cooperating with hoisting greatly improves the construction speed.

[0043] The side frame 1 and the top frame 2 of the unpowered steel member transfer tool form a portal structure, providing space for the steel member to move up and down between the two side frames 1. At the same time, this structure has a certain structural strength, enabling it to lift heavier steel members and having a large load capacity.

[0044] Although the present utility model uses manual labor as the power and for operation, since the vertical lifting and lowering of the steel member can be achieved without manual handling and moving, after being lifted, the operator can easily push the unpowered steel member transfer tool to move, and can stop and park the unpowered steel member transfer tool at any time, with simple and convenient operation.
