Description

Technical Field

[0001] The utility model relates to the technical field of steel, in particular to a hot-rolled H-shaped steel mechanical sample clamping and lifting tool. Background Art

[0002] According to the standard requirements, samples need to be taken from each furnace of steel for mechanical property testing. When sampling, a hot saw is used to cut a 1.5-meter-long large sample from the middle or tail of the entire steel (length 50 to 100 meters, temperature around 600°C). The sample is then clamped by a sling at the flange position and lifted to the designated area. Small samples are then cut by flame cutting and sent to the mechanical testing laboratory for testing.

[0003] Existing H-beam mechanical property samples are lifted by vertical steel plate lifting clamps. Due to the small jaws and high sample temperature (about 600°C), it is not easy to operate when clamping the steel flange. The lifting clamp needs to be supported by hand to clamp the steel, which poses safety risks such as burns and collisions, and the sampling efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide a hot-rolled H-shaped steel mechanical sample clamping and lifting tool to solve the problem that it is difficult to operate when clamping the steel flange, and the lifting clamp needs to be supported by hand to clamp the steel, which poses safety risks such as burns and collisions, and the sampling efficiency is low.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a hot-rolled H-shaped steel mechanical sample clamping and lifting tool, including an L-shaped rod, which is detachably arranged on the front side of the outer wall of the lifting clamp, and a fixing rod is movably arranged at the right end of the L-shaped rod, and an installation groove is opened at the left end of the fixing rod, and a connecting rod is fixed to the right end of the L-shaped rod, and the connecting rod is movably arranged in the installation groove, and a handle is fixed to the right end of the fixing rod.

[0006] Preferably, two first threaded grooves are provided on the front side of the outer wall of the lifting clamp, and two first threaded holes are provided on the front side of the outer wall of the L-shaped rod. The two first threaded holes are respectively threadedly connected with first bolts, and the threaded ends of the two first bolts are respectively connected with the internal threads of the two first threaded grooves.

[0007] Preferably, a rubber sleeve is fixed to the outer wall of the handle, and the outer wall of the rubber sleeve is provided with anti-slip patterns.

[0008] Preferably, a plurality of second thread grooves are provided on the front side of the outer wall of the connecting rod, a second thread hole is provided on the front side of the outer wall of the fixing rod, the second thread hole is threadedly connected with a second bolt, and the threaded end of the second bolt is threadedly connected to the internal thread of the second thread groove.

[0009] Preferably, the inner top surface and the bottom surface of the installation groove are respectively provided with sliding grooves, the top surface and the bottom surface of the connecting rod are respectively fixed with sliding rods, and the two sliding rods are respectively slidably arranged in the two sliding grooves.

[0010] Preferably, the thickness of the rubber sleeve is 1 cm.

[0011] Compared with the prior art, a hot-rolled H-beam mechanical sample clamping and lifting tool using the above technical solution has the following beneficial effects:

[0012] 1. During use, the lifting clamp can accurately and quickly clamp the high-temperature steel through the L-shaped rod, fixed rod and handle, which improves work efficiency. At the same time, it helps to avoid burns caused by close contact with high-temperature samples by the sampling personnel or injuries caused by the rotation of the samples during the lifting process, thereby improving safety;

[0013] 2. During use, by turning the first bolt, the operator can disassemble and assemble the L-shaped rod, which is convenient for the operator to maintain or replace, thereby improving the flexibility and maintainability of the tool. The rubber sleeve and anti-slip pattern provide the operator with a better hand feel and grip comfort when holding the handle, reducing the operator's hand fatigue. At the same time, it helps to increase the friction of the handle surface, improve the operator's control over the handle, effectively prevent the handle from accidentally sliding during operation, and improve operational safety;

[0014] 3. During use, by turning the second bolt, the length between the L-shaped rod and the fixed rod can be adjusted, and the application range is wider. The sliding groove and the sliding rod can prevent the L-shaped rod and the fixed rod from deviating, increase the stability of the L-shaped rod and the fixed rod, and improve the reliability of the tool.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 4 As shown, a hot-rolled H-shaped steel mechanical sample clamping and lifting tool includes an L-shaped rod 1, which is detachably arranged on the front side of the outer wall of a lifting clamp 2, a fixing rod 3 is movably arranged at the right end of the L-shaped rod 1, a mounting groove 4 is opened at the left end of the fixing rod 3, a connecting rod 5 is fixed to the right end of the L-shaped rod 1, the connecting rod 5 is movably arranged in the mounting groove 4, and a handle 6 is fixed to the right end of the fixing rod 3.

[0022] In use, the operator first installs the L-shaped rod 1 at a specific angle on the front side of the outer wall of the lifting clamp 2. When clamping the sample, the operator holds the handle 6 so that the lifting clamp 2 can accurately and quickly clamp the flange position of the steel section. In the process of lifting, the center of gravity of the original lifting clamp 2 will not be changed due to the weight of the L-shaped rod 1. When the sample is lifted to the air above the designated area, the operator can adjust the direction and landing position of the sample through the L-shaped rod 1, the fixed rod 3 and the handle 6. It is beneficial to enable the lifting clamp 2 to accurately and quickly clamp the high-temperature steel section through the L-shaped rod 1, the fixed rod 3 and the handle 6, thereby improving work efficiency, and at the same time, it is beneficial to avoid the sampler from being scalded by close contact with the high-temperature sample or the sample rotating during the lifting process, thereby improving safety.

[0023] like Figure 1-Figure 3 As shown, two first thread grooves 7 are provided on the front side of the outer wall of the lifting clamp 2, and two first thread holes 8 are provided on the front side of the outer wall of the L-shaped rod 1. The two first thread holes 8 are respectively threadedly connected with first bolts 9, and the threaded ends of the two first bolts 9 are respectively connected with the internal threads of the two first thread grooves 7.

[0024] During use, by rotating the first bolt 9 , the operator can disassemble and assemble the L-shaped rod 1 , thereby facilitating maintenance or replacement by the operator, thereby improving the flexibility and maintainability of the tool.

[0025] like Figure 1-Figure 4 As shown, a rubber sleeve 10 is fixed to the outer wall of the handle 6, and the outer wall of the rubber sleeve 10 is provided with anti-slip grooves 11. A plurality of second threaded grooves 12 are provided on the front side of the outer wall of the connecting rod 5, and a second threaded hole 13 is provided on the front side of the outer wall of the fixing rod 3. The second threaded hole 13 is threadedly connected with a second bolt 14, and the threaded end of the second bolt 14 is threadedly connected to the internal thread of the second threaded groove 12.

[0026] In use, the rubber sleeve 10 and the anti-slip pattern 11 provide a better hand feel and grip comfort when the operator holds the handle 6, reducing the operator's hand fatigue. At the same time, it is helpful to increase the friction of the handle surface, improve the operator's control over the handle 6, and effectively prevent the handle 6 from accidentally sliding during operation, thereby improving operational safety. By turning the second bolt 14, the length between the L-shaped rod 1 and the fixed rod 3 can be adjusted, and the scope of application is wider.

[0027] like Figure 3 and Figure 4 As shown, the inner top and bottom surfaces of the mounting groove 4 are respectively provided with slide grooves 15, the top and bottom surfaces of the connecting rod 5 are respectively fixed with slide rods 16, the two slide rods 16 are respectively slidably arranged in the two slide grooves 15, and the thickness of the rubber sleeve 10 is 1 cm.

[0028] During use, the slide groove 15 and the slide rod 16 can help prevent the L-shaped rod 1 and the fixed rod 3 from deflecting, thereby increasing the stability of the L-shaped rod 1 and the fixed rod 3 and improving the reliability of the tool.
