Description

Technical Field

[0001] This utility model belongs to the field of jack technology, and in particular relates to a portable and simple jack. Background Technology

[0002] Steel plant maintenance often requires jacks for lifting operations, such as equipment repair. Workshop renovation or new construction projects also necessitate pipeline installation. Typically, horizontal pipes are placed on pipe supports. When vertical pipes are connected to horizontal pipes, one person on the ground must erect the pipe, while another person on scaffolding holds the welded elbow (or tee) at the top of the pipe. Ground personnel then lift the vertical pipe to a certain height for connection. After connection, the personnel at the height perform welding. Throughout this process, ground personnel must continuously lift the pipe to maintain a certain height, which is extremely strenuous. Welding slag can fall on the ground personnel, posing a safety hazard. Furthermore, even slight movement by ground personnel can widen the gap at the pipe connection, affecting the weld quality. Summary of the Invention

[0003] The purpose of this invention is to provide a portable, simple jack to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A portable simple jack includes a base, on which a lead screw is fixed, and a lifting plate is threaded onto the lead screw. The top of the lifting plate has several grooves of different diameters.

[0006] Furthermore, wing plates are welded to both sides of the lifting plate.

[0007] Furthermore, several ribs are welded to the outer wall at the bottom of the lead screw, and the bottom ends of the ribs are welded to the base.

[0008] Furthermore, a round tube is engaged in any of the grooves of the lifting plate.

[0009] This utility model has the following beneficial effects:

[0010] 1. This utility model can be used for equipment lifting and pipe welding assistance during workshop maintenance. It has a simple structure, is easy to carry, and is highly practical.

[0011] 2. The lifting plate can clamp pipes of different outer diameters, making it suitable for the installation and connection of various pipes. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 This is a schematic diagram of the structure of this utility model when it is snapped into a round tube.

[0014] The components are: 1. base; 2. lead screw; 3. lifting plate; 4. groove; 5. wing plate; 6. rib plate; 7. round tube. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0016] like Figure 1-2 As shown, a portable simple jack includes a base 1, a lead screw 2 fixed on the base 1, and a lifting plate 3 threaded onto the lead screw 2. The top of the lifting plate 3 has several grooves 4 of different diameters. The diameter of the grooves 4 is made according to the outer diameter of different pipes, so that the grooves 4 of different diameters can engage pipes of different outer diameters.

[0017] The lifting plate 3 has wing plates 5 welded on both sides.

[0018] Several ribs 6 are welded to the outer wall of the bottom end of the lead screw 2, and the bottom end of the ribs 6 is welded to the base 1.

[0019] A round tube 7 is inserted into any one of the grooves 4 of the lifting plate 3.

[0020] The working principle of this utility model is as follows:

[0021] When welding pipes, one person places the pipe on a support block (such as a stool in the workshop, a movable step ladder, etc.) or directly on the scaffolding (depending on the length of the vertical pipe). The vertical pipe is placed in the corresponding groove 4 according to its outer diameter. Another person on the scaffolding holds the elbow or tee at the top of the vertical pipe, while the person below uses a hammer to strike the wing plate 5, causing the lifting plate 3 to rotate on the screw 2, thereby adjusting the height of the vertical pipe and connecting it. After the connection is completed, the person below leaves, and the welder performs the welding on the scaffolding.

[0022] When lifting the equipment, cut a section of round pipe 7 of appropriate length, place it in the corresponding groove 4 according to its outer diameter, and place this utility model below the lifting position. Use a hammer to strike the wing plate 5 and the lifting plate 3 to rotate and rise on the screw 2, so that the top of the round pipe 7 is below the lifting point of the equipment, thereby lifting the equipment (such as lifting one corner of the equipment).

[0023] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.

[0024] The technologies, shapes, and structures not described in detail in this utility model are all known technologies.
