Description

Technical Field

[0001] The utility model relates to the field of slab clamps, in particular to a device for preventing jaws of a slab clamp from falling off. Background Art

[0002] The slab clamp is a device used to lift and transfer slabs. The jaws are fixed with jaws by bolts and are used to directly contact the slab. According to actual usage experience, the newly made slab is in a hot state. The slab clamp will inevitably be heated when it comes into contact with it, and the temperature will drop when it is away from the slab. The increase and decrease in temperature will cause thermal expansion and contraction of the material, which will easily cause the bolts to break under stress on the slab clamp. In severe cases, it will cause the slab to fall during lifting, which is very dangerous. Therefore, a slab clamp jaw anti-falling device that can effectively cope with thermal expansion and contraction is needed. Utility Model Content

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1-3As shown, the slab clamp teeth anti-falling device described in this embodiment includes a heat pipe and an inclined hole 2 opened on the slab clamp 1, the inclined hole 2 is filled with a heat conductor 3 and the bottom of the inclined hole 2 is close to the clamp teeth fixing bolt 4, the heat conductor 3 is heat-conducting oil, and can also be heat-conducting grease, which can effectively fill the gap between the heat pipe and the inclined hole 2, which is beneficial to heat conduction, and the heat pipe includes an inclined pipe section 5 and a vertical pipe section 6, the inclined pipe section 5 is inserted in the inclined hole 2 and the inclined pipe section 5 is filled with a phase change material 7, such as water, and a placeholder rod 8 is coaxially arranged at the bottom of the inclined pipe section 5. The diameter is not less than half of the inner diameter of the inclined tube section 5, so that the phase change material can gather and contact the inner wall of the inclined tube section 5 and increase the heat exchange area, which is beneficial to the heat absorption of the phase change material. The upper end of the inclined hole 2 is screwed with a plug 9. Specifically, the upper end of the inclined hole 2 has an internal thread, and the plug 9 has an external thread. The inner ring of the plug 9 is provided with a sealing gasket 10 that cooperates with the inclined tube section 5. The plug can prevent the heat conductor 3 from overflowing the inclined hole 2. Preferably, a step 11 is also coaxially provided on the plug 9, and a cutting surface is symmetrically provided on the step 11 to facilitate screwing the plug 9 with an open-end wrench;

[0020] The vertical pipe section 6 fits into the slab clamp 1 and is provided with a plurality of fins 12. The slab clamp 1 is also provided with a blast pipe 13 parallel to the vertical pipe section 6. The blast pipe 13 is provided with a plurality of air holes facing the vertical pipe section 6. The blast pipe 13 is connected to the fan through a flexible hose 14. The flexible hose 14 is a stainless steel hose. The slab clamp 1 is provided with a pipe clamp 15 that cooperates with the flexible hose 14.

[0021] A heat pipe adjustment clamp is also provided in the inclined hole 2. The heat pipe adjustment clamp includes a base plate 16, a center column 17 fixed on the base plate 16, and a plurality of claws 18 hinged at one end to the base plate 16. The plurality of claws 18 are evenly distributed circumferentially along the cross-section of the center column 17. A circle of return spring 19 is commonly provided on the outside of all the claws 18. When installing the heat pipe, first place the heat pipe adjustment clamp into the inclined hole 2, and then insert the inclined pipe section 5. When the bottom end of the inclined pipe section 5 pushes the heat pipe adjustment clamp against the bottom of the inclined hole 2, the plurality of claws 18 are pushed open to keep the inclined pipe section 5 coaxial with the inclined hole 2, and stop when the bottom end of the inclined pipe section 5 is tightly against the center column 17.

[0022] The slab clamp 1 is also provided with a heat reflecting plate 20 parallel to the blast pipe 13. The height of the heat reflecting plate 20 is greater than the height of the hot air pipe 13 and the height of the part with fins 12 on the riser section 6, and the width of the heat reflecting plate 20 is greater than the diameter of the hot air pipe 13 and the diameter of the fins 12, so that the heat reflecting plate 20 can block the hot air pipe 13 and the part with fins 12 on the riser section 6 at a horizontal angle, which can significantly reduce the impact of heat radiation from the hot slab and avoid the blast pipe 13 and the riser section 6 from heating up due to heat radiation. The heat reflecting plate 20 is a mirrored aluminum plate.

[0023] In order to ensure the heat conduction effect, inclined holes 2 and heat conduction pipes can be symmetrically arranged on the front and rear sides of the slab clamp 1.

[0024] The working principle of this embodiment is:

[0025] The jaws 21 are heated and heated up and transfer the heat to the jaws of the slab clamp 1. The temperature around the jaw fixing bolt 4 rises, and the phase change material in the inclined pipe section 5 absorbs heat and evaporates to reach the vertical pipe section 6 and is cooled by air and condensed again and falls back into the inclined pipe section 5, thereby realizing heat transfer. Heat is not accumulated around the jaw fixing bolt 4 to cause a significant temperature rise. Compared with the prior art, in this embodiment, a heat pipe is used to effectively conduct the heat near the jaw fixing bolt 4 to the outside and cool it down by air cooling. This can effectively avoid the sharp temperature rise around the jaw fixing bolt 4 when clamping the hot slab, and reduce the temperature difference around the jaw fixing bolt 4 in the working and shutdown states, that is, the thermal expansion and contraction phenomenon is reduced, and the safe operation of the jaw fixing bolt 4 is ensured.
