[0002] In modern warfare, the main way to ensure wartime oil supply is through oil pipeline transportation. Ensuring that the oil pipeline reaches the designated location in a timely and accurate manner to ensure the smooth flow of oil during wartime is a basic task that must be done well in military struggle preparation. For pipelines that are frequently connected and disassembled in large quantities to replace the transportation site, frequent connection and disassembly operations are performed between steel pipes and joints.

[0003] Generally, steel pipelines are made of several steel pipes connected by joints. During the connection process, the steel pipes (6m in example) are laid flat on the ground one by one along the pipeline direction. When the steel pipes are connected, the traditional method is to move them one by one with a crowbar and then connect them. When the steel pipes need to be erected, it is laborious and time-consuming. During the long-distance continuous laying process, a special tool is needed to pry and erect the steel pipes.

[0024] Figure 1In the present invention, the long rod body 1 and the bracket 2 are welded to form a lever bracket. The long rod body 1 is a bending lever, and the long rod body 1 includes a handle portion 101, a rod body portion, and an arc-shaped hook portion 102. The connection between the handle portion 101 and the rod body portion is a bending point 105. The rod body portion has a bending point 2 106 near the lower part, an upper rod section 100 located above the bending point 2 106, and a lower rod section located below the bending point 2 106. The lower part of the arc-shaped hook portion is connected to the bracket 2. The upper end of the upper part of the long rod body 1 is bent into a handle portion 101 which is at an angle of 90° with the long rod body, which is a hand-held portion, and is convenient for applying force during the action and process of the sled and the bracket. The lower end of the lower part of the long rod body 1 is bent into an arc-shaped hook portion 102. The long rod body 1 and the arc-shaped hook portion 102 form a J shape, which is used to support the outer circle of a steel pipe (for example, a length of 6m). The hook head of the arc-shaped hook portion is milled into a triangular wedge structure, which is convenient for the steel pipe to be inserted into or separated from the inner circle of the arc-shaped hook. The triangular wedge structure of the hook head of the arc-shaped hook portion does not interfere with the outer circle of the steel pipe. The cross section of the triangular wedge structure is a triangle, and one inner angle 107 of the triangle is located at the inner side 109 of the hook head of the arc-shaped hook portion 102, and the other two inner angles of the triangle are located at the outer side 108 of the hook head of the arc-shaped hook portion 102.

[0025] The lower rod section and the arc-shaped hook portion 102 of the long rod body 1 are bent at an angle in the vertical direction of the upper rod section 100 and the handle portion 101. Before bending at the second bending point: the plane A where the handle portion 101, the first bending point, and the upper rod section axis are located coincides with the plane B where the arc-shaped hook portion 102, the lower rod section, and the axis of the bracket 2 are located. After bending at the second bending point: the angle between the plane A where the handle portion 101, the first bending point, and the upper rod section axis are located and the plane B where the arc-shaped hook portion 102 and the lower rod section axis are located is 140°. The upper part of the bracket 2 is an arc-shaped bent portion 201, and the arc-shaped bent portion 201 contacts the outer edge of the arc-shaped hook portion 102 at the lower part of the long rod body 1. The lower part of the bracket 2 is a straight section, and the head of the straight section is a flat wedge-shaped skid head 202. The arc-shaped contact part is welded firmly. The angle a2 between the support rod axis and the axis of the upper rod section 100 is an acute angle.

[0026] The end of the handle 101 protrudes from the hook of the arc-shaped hook 102, which is convenient for manual two-handed operation of the handle. The handle 101 is lengthened to increase the holding position of the two hands and increase the holding force. When in use, the lever bracket can be operated with greater force to balance the instantaneous greater force between the pry and the frame and between the frame and the inner arc of the arc-shaped hook 102.

[0027] Figure 6 , 78, the lever bracket 10 of the present invention is mainly used to pry and support the steel pipe 5 in the pipeline. It can be used as a pry or a frame. It can be used alone, that is, only as a pry or a frame, or it can be pried first and then framed, a one-time operation. It can also be used in conjunction with the assembly hook. The lever bracket 10 of the present invention first pries up the steel pipe 5, and then the assembly hook 6 hooks the steel pipe and lifts it up, and then the lever bracket 10 of the present invention holds the steel pipe 5. In addition, it also has the function of moving the steel pipe when two lever brackets 10 are used together. The specific method of use is as follows:

[0028] ① Use of crowbar: Take a 6m long steel pipe as an example. When the steel pipe 5 is on the ground and needs to be moved, use the sled head under the bracket to pry the steel pipe and use it as a crowbar.

[0029] ② When used as a bracket: Use the wedge-shaped sled head 202 to sled (the sled head refers to the sled head at the lower end of the lever bracket) the steel pipe, and then use the assembly hook to hook the steel pipe to the arc position of the lever bracket to temporarily support the steel pipe for easy maintenance of the steel pipe head.

[0030] ③ Use for both prying and erecting: When the steel pipe is not too long or too heavy (taking a 3m long steel pipe as an example), you can choose a concave position on the ground where the steel pipe is placed, and the lever bracket is horizontal to the ground. Use the wedge-shaped sled head 202 to pry up the steel pipe on the flat ground near the end, and then push it inward, so that the steel pipe rolls to the position of the arc-shaped hook part 102 of the lever bracket, and then rotate the lever bracket to make the outer circle of the steel pipe fall into the inner arc of the arc-shaped hook part 102, and then vertically lift the lever bracket, and the steel pipe is also erected during the process of the lever bracket. Since the angle a2 between the axis of the support rod and the axis of the upper rod section 100 is set as an acute angle, it is more convenient to rotate the lever bracket.

[0031] ④ Partial movement of steel pipe: When two lever brackets are used together, one of them acts as a pry and a bracket, and the other acts as a hook and a bracket. After the steel pipe is lifted up by the two lever brackets, the lever bracket can be moved a small distance along the axis.
