[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] refer to Figure 1 and Figure 2As shown, the utility model provides a roof truss diagonal brace hoisting tool, including a base 1, a column 2, a platform 3 and a winch 4, the column 2 is vertically installed on one side of the top surface of the base 1, the platform 3 is fixedly installed on the column 2, the winch 4 is installed on the platform 3, and the pulley of the winch 4 is installed on the top of the column 2, and the pulley is located above the base 1 and is arranged opposite to the column 2. After passing the top of the pulley, the steel wire rope of the winch 4 extends downward and directly binds the roof truss diagonal brace to be welded, and then the winch 4 is started to hoist the roof truss diagonal brace to a suitable height. The welding operator on the roof truss directly welds the diagonal brace to the roof truss, and the welding operation of the roof truss diagonal brace can be completed without using a hoisting machine, thereby reducing the construction cost.

[0020] An inclined rod support 5 is provided between the column 2 and the base 1, the top end of the inclined rod support 5 is connected to the side surface of the column 2, the bottom end of the inclined rod support 5 is connected to the base 1, and the platform 3 is installed at the position of the column 2 corresponding to the top end of the inclined rod support 5. The inclined rod support 5 has the effect of improving the overall stability of the lifting tool, and can prevent the column 2 from tilting during the process of lifting the diagonal brace of the roof truss, thereby improving the safety of the construction operation.

[0021] As a specific application of the base 1 in the above embodiment, the base 1 is an isosceles triangle structure, the top angle of the base 1 is an acute angle, the bottom end of the column 2 is fixed to the upper surface of the bottom edge of the base 1, and the pulley is above the base 1 and close to the vertex of the base 1. The triangular structure design of the base 1 itself makes it have sufficient stability and rigidity. The positional relationship between the pulley, the column 2 and the base 1 makes it difficult for the overall center of gravity of the hoisting tool to tilt when hoisting the roof truss diagonal brace, and the stability is stronger.

[0022] Furthermore, the diagonal support 5 includes three diagonal support rods, two of which are symmetrically distributed on both sides of the column 2 in the length direction of the bottom edge of the base 1, and the bottom end of the other diagonal support rod is connected to an angle iron, the angle iron is parallel to the bottom edge of the base 1, and the two ends of the angle iron are respectively connected to the upper surfaces of the two waist edges of the base 1. The three diagonal support rods and the column 2 and the base 1 form a triangular support state, further improving the overall stability of the lifting tool.

[0023] The angle between the two diagonal braces connected to the bottom edge of the base 1 and the horizontal plane is greater than the angle between the diagonal braces connected to the angle iron and the horizontal plane. This arrangement makes it more difficult for the overall center of gravity of the lifting tool to tilt toward the side of the diagonal brace being lifted, further enhancing the stability when lifting the diagonal brace of the roof truss.

[0024] The pulley is located directly above the area between the vertex of the base 1 and the angle iron. The diagonal brace of the roof truss can be directly placed in the area between the vertex of the base 1 and the angle iron. At this time, the diagonal brace of the roof truss is suspended, which makes it easier to wrap the wire rope around the diagonal brace to tie it up, making construction work more convenient.

[0025] A hanging rod is vertically installed on one side of the top end of the column 2 facing the vertex of the base 1, and a pulley is installed at the bottom of the end of the hanging rod away from the column 2.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
