[0001] The utility model relates to the technical field of drill pipe lifting magnet, concretely to a portable drill pipe lifting magnet. BACKGROUND

[0002] The drill pipe lifting magnet is a lifting device specially used in oil drilling operation, which is unique in design and can firmly clamp the drill pipe to ensure the stability and safety of the drill pipe during lifting, hanging and moving.

[0003] The existing drill pipe lifting magnet is not convenient to use. When the operator uses it, the drill pipe needs to be inserted into the inside of the lifting magnet, and then the cover plate movably installed at one end of the lifting magnet needs to be fixed. After use, the cover plate needs to be opened first, and then the drill pipe needs to be pulled out from the inside of the main body. Since there is a certain friction between the drill pipe and the main body of the lifting magnet, the operator needs to exert a certain force to pull out the drill pipe from the inside of the main body, which can make the operator feel tired quickly, thereby affecting the use efficiency.

[0004] Therefore, a portable drill pipe lifting magnet is proposed. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at providing a portable drill pipe lifting magnet to solve the problems raised in the background art. To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a portable drill pipe lifting magnet, comprising a fixed plate and a drill pipe clamp, two side plates are welded on one side of the fixed plate, two supporting slide rods are installed between the two side plates, the number of drill pipe clamps is two, two drill pipe clamps are respectively slidably sleeved on the outer sides of the two supporting slide rods, one fixed assembly is respectively welded on one side of each of the two drill pipe clamps, two positioning holes are formed on one side of the fixed plate, the positioning holes are used in cooperation with the fixed assembly, and one clamping groove is respectively formed on one side of each of the two drill pipe clamps.

[0006] Preferably, one lifting groove is respectively formed on both sides of the fixed plate, and a limiting plug is installed in the inside of the lifting groove.

[0007] Preferably, two sliding grooves are formed on one side of the fixed plate, two supporting sliding blocks are respectively welded on the bottoms of the two drill pipe clamps, and the supporting sliding blocks are slidably installed in the inside of the sliding grooves.

[0008] Preferably, a plug is installed in one end of the supporting slide rod, and a limiting plate is welded on one end of the supporting slide rod.

[0009] Preferably, the fixed assembly comprises a fixed groove, and the fixed groove is welded on one side of the drill pipe clamp.

[0010] Preferably, the inside of the fixing groove is fixed with a sleeve rod, and the outside of the sleeve rod is slidably sleeved with a sliding plate.

[0011] Preferably, the bottom of the sliding plate is welded with a fixed insertion rod, and the top of the sliding plate is welded with a control pull rod, and the top end of the control pull rod is slidably extended out of the inside of the fixing groove.

[0012] Compared with the prior art, the portable drill rod elevator has the following beneficial effects:

[0013] By controlling the movement of the two drill rod clamps, the two clamping grooves can clamp the outside of the drill rod. When the two drill rod clamps are moved so that the drill rod is clamped between the two clamping grooves, the bottom of the fixing assembly is fixed in the inside of the positioning hole, thereby fixing the positions of the two drill rod clamps and stably clamping the outside of the drill rod. Then, the drill rod can be clamped and moved. When disassembling, the bottom end of the fixing assembly is extracted from the inside of the positioning hole, and the drill rod clamp is controlled to slide along the mounting direction of the supporting slide rod, so that the drill rod clamped between the two clamping grooves is taken out. In the process of taking out the drill rod, the frictional force between the two clamping grooves and the outside of the drill rod can be ignored, so that the operator can easily separate the drill rod. The operator can conveniently disassemble and assemble the drill rod, thereby improving the work efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0024] In example 2, the two sides of the fixed plate 1 are provided with one lifting groove 101 respectively, and the inside of the lifting groove 101 is provided with a limiting plug 102, one side of the fixed plate 1 is provided with two sliding grooves 104, and the bottom of each of the two drill rod clamps 2 is welded with two supporting sliding blocks 202, and the supporting sliding blocks 202 are slidably installed in the inside of the sliding grooves 104, the inside of one end of the supporting slide rod 4 is provided with a plug 401, and one end of the supporting slide rod 4 is welded with a limiting plate, the fixing assembly 3 comprises a fixing groove 301, and the fixing groove 301 is welded with one side of the drill rod clamp 2, the inside of the fixing groove 301 is fixed with a sleeve rod 304, the outside of the sleeve rod 304 is slidably provided with a sliding plate 302, the bottom of the sliding plate 302 is welded with a fixed plug 303, the outside of the sleeve rod 304 is provided with a spring 305, and the top of the sliding plate 302 is welded with a control pull rod 306, and the top end of the control pull rod 306 is slidably extended out of the inside of the fixing groove 301.

[0025] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the lifting groove 101 opened on both sides of the fixed plate 1 can facilitate the lifting of the lifting device to the fixed plate 1, and the inside of the lifting groove 101 is provided with a limiting plug rod 102, which can be inserted into the lifting device inside the lifting groove 101 to limit the lifting device from being separated, and since the two supporting sliding rods 4 are slidingly inserted between the two side plates 5, the two supporting sliding rods 4 can be removed from between the two side plates 5, and when the supporting sliding rod 4 is removed, the plug bolt 401 inside one end of the supporting sliding rod 4 can be pulled out, and then the entire supporting sliding rod 4 can be pulled out from the inside of the side plate 5. After the supporting sliding rod 4 is pulled out, the two drill rod clamps 2 can be removed, so that the drill rod clamps 2 can be repaired and replaced. When the drill rod clamp 2 moves, the operator can hold the control pull rod 306, and then move the bottom end of the fixed plug rod 303 welded at the bottom of the sliding plate 302 to the top of the positioning hole 103, and then the rebound force generated by the compressed spring 305 can push the fixed plug rod 303 into the inside of the positioning hole 103 for fixation, thereby limiting the movement of the drill rod clamp 2. When disassembling, the operator holds the control pull rod 306, and then pulls the control pull rod 306 upwards, so that the bottom end of the fixed plug rod 303 is separated from the inside of the positioning hole 103, and the drill rod clamp 2 can be moved again, so that the two drill rod clamps 2 can be separated.
