Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, specifically a heat insulation and protection device for lifting equipment. Background Technology

[0002] In the metal smelting industry, the hoisting of high-temperature molten metal is a critical and frequently performed operation. During this process, the extremely high temperature of the molten metal, coupled with the large amount of high-temperature fumes generated during oxygen refining, can easily damage the equipment above. Furthermore, molten metal may splash out during oxygen refining, causing serious injury to personnel and equipment. Moreover, when the crane malfunctions, the high temperature environment prevents timely repairs, forcing maintenance to wait until the temperature drops, resulting in significant downtime losses.

[0003] However, existing protective measures have problems such as large equipment footprint, high investment cost, low safety factor, unstable structure and complex maintenance. Furthermore, current protective equipment generally focuses on stability during the hoisting process and does not consider the problem of heat damage to the hoisting equipment caused by the rise of high-temperature gas. Summary of the Invention

This device is used to solve the problem that high temperature fumes can easily damage lifting equipment and equipment and cause downtime losses when lifting high temperature liquid metal in the metal smelting industry. In addition, existing protective measures have problems such as large footprint, high cost, and failure to specifically address heat damage to lifting equipment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a heat insulation and protection device for a lifting device, including heat insulation plates disposed in the grooves on both sides of the lifting beam. The heat insulation plates are composed of a semi-circular plate and a rectangular plate. The rectangular plate is fixedly disposed in the groove on the side of the lifting beam, and a guide plate is provided on the bottom surface of the semi-circular plate.

[0006] In a preferred embodiment, the main body of the guide plate is a triangular heat-resistant steel plate, and a fiberboard is bonded and fixed to the outer surface of the heat-resistant steel plate with an adhesive.

[0007] In a preferred embodiment, a fiberboard is bonded and fixed to the bottom surface of the semicircular plate using an adhesive.

[0008] In a preferred embodiment, the fiberboard is a multi-piece L-shaped board structure, with L-shaped guide plate mounting grooves spaced apart between adjacent fiberboards, and the guide plates are fixed in the guide plate mounting grooves.

[0009] In a preferred embodiment, the fiberboard is a high-temperature resistant aluminum silicate fiberboard or an alumina fiberboard.

[0010] In a preferred embodiment, a flow guide plate is provided between two adjacent fiberboards.

[0011] In a preferred embodiment, the adhesive is an inorganic high-temperature adhesive, preferably a phosphate-based adhesive or a silicate adhesive.

[0012] The heat insulation and protection device for lifting equipment provided by this utility model has the following beneficial effects by adopting the above-described structure:

[0013] (1) The heat insulation board can effectively block the high-temperature fumes and splashes generated by the high-temperature liquid metal, thus providing effective protection for the upper hoisting equipment;

[0014] (2) The guide plate can change the flow direction of high temperature flue gas, reduce its direct impact on the beam of the lifting device, and its triangular shape enhances the structural stability of the device, making it better suited to high temperature working environment.

[0015] (3) When the vehicle malfunctions and needs maintenance, the heat insulation plate can effectively prevent the maintenance personnel from being injured by the rising high-temperature airflow.

[0016] (4) The guide plate can accelerate the speed at which the heat flow spreads to the surroundings, reduce the heat flow staying at the hanging beam, and reduce the thermal pressure on the device. Attached Figure Description

[0025] Example 1:

[0026] like Figure 1-5 A heat insulation and protection device for a lifting device includes a heat insulation plate 2 disposed in grooves 101 on both sides of the lifting beam 1. The heat insulation plate 2 is composed of a semi-circular plate 201 and a rectangular plate 202. The rectangular plate 202 is fixedly disposed in the groove 101 on the side of the lifting beam 1, and a guide plate 5 is provided on the bottom surface of the semi-circular plate 201.

[0027] In a preferred embodiment, the main body of the guide plate 5 is a triangular heat-resistant steel plate 3, and a fiberboard 6 is bonded and fixed to the outer surface of the heat-resistant steel plate 3 by an adhesive 7.

[0028] In a preferred embodiment, a fiberboard 6 is bonded and fixed to the bottom surface of the semi-circular plate 201 by an adhesive 7.

[0029] In a preferred embodiment, the fiberboard 6 is a multi-piece L-shaped plate structure, with L-shaped guide plate mounting grooves 4 spaced apart between adjacent fiberboards 6, and the guide plate 5 is fixed in the guide plate mounting groove 4.

[0030] Example 2:

[0031] The fiberboard 6 is a high-temperature resistant aluminum silicate fiberboard or an alumina fiberboard.

[0032] Fiberboard 6 can also be replaced with calcium silicate board, aerogel board, silicon carbide board, or boron nitride board. All of the aforementioned high-temperature resistant boards can withstand high temperature and pressure of over 1000℃, effectively preventing the rising high-temperature airflow from harming hoisting equipment or maintenance personnel.

[0033] Example 3:

[0034] A flow guide plate 8 is provided between two adjacent fiberboards 6.

[0035] The guide plate 8 can form a sloping airflow upward channel, realize the rapid diffusion of hot airflow to both sides of the hanger, minimize the heat flow staying below the heat insulation plate 2, and reduce the temperature below the heat insulation plate 2.

[0036] Example 3:

[0037] The adhesive 7 is an inorganic high-temperature adhesive, and phosphate adhesives or silicate adhesives are selected.

[0038] Alternatively, organic-inorganic composite adhesives can be selected, such as silicone resin adhesives or phosphate-organic silicone composite adhesives. The choice should be made according to the temperature requirements of the lifting equipment. When it is necessary to withstand short-term high temperatures (less than 1000°C), silicone resin or phosphate adhesives (such as aluminum dihydrogen phosphate) should be given priority. When it is necessary to withstand long-term high temperatures (greater than 1000°C), ceramic sintered or glass-ceramic adhesives are more reliable.

[0039] In addition, considering that the adhesive strength may decrease at high temperatures, mechanical fixation (such as bolts or clips) can be used to fix load-bearing or critical parts of the structure.
