Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting technology, specifically to a cutting device for steel composite plates used in tunnels with a cooling structure. Background Technology
[0002] Steel composite plates for tunnels are a widely used material in tunnel construction, primarily used to improve the wear resistance and corrosion resistance of steel formwork trolleys, thereby extending their service life. These composite plates are typically made by hot-rolling stainless steel and ordinary steel plates, combining the corrosion resistance of stainless steel with the toughness of ordinary steel plates, achieving a perfect balance between low cost and high performance. Before installation, these composite plates need to be cut to the required dimensions.
[0003] Currently, during the use of tunnel steel composite plate cutting devices, the cutting disc generates a large amount of heat during friction with the composite plate, which reduces the service life of the cutting disc and also reduces the cutting quality. To address this, we propose a tunnel steel composite plate cutting device with a cooling structure. Utility Model Content
[0004] The purpose of this utility model is to provide a tunnel steel composite plate cutting device with a cooling structure. When cutting tunnel steel composite plates, it can cool the cutting disc to extend the service life of the cutting disc and improve the cutting quality. This solves the problem that in the current tunnel steel composite plate cutting devices, the cutting disc generates a lot of heat during friction with the composite plate, which reduces the service life of the cutting disc and also reduces the cutting quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel steel composite plate cutting device with a cooling structure, comprising a fixed base and a lifting plate. A rotating base is rotatably mounted on the upper surface of the fixed base. Sliding rods are symmetrically fixedly connected to both sides of the upper surface of the rotating base. Sliding sleeves are fixedly mounted on both sides of the upper surface of the lifting plate, and the two sliding rods pass through the two sliding sleeves respectively. A protective cover is fixedly mounted on the front surface of the lifting plate, and an air inlet pipe is fixedly mounted on the front surface of the protective cover. A rotating motor is fixedly mounted on the upper surface of the lifting plate near the rear surface. The output end of the rotating motor is fixedly connected to a rotating shaft through a safety coupling. A cutting disc and a fan blade are fixedly mounted on the outer surface of the rotating shaft, and the cutting disc and the fan blade are located inside the protective cover and the air inlet pipe respectively.
[0006] Preferably, the outer surfaces of both slide rods are spirally wound with helical springs between the lifting plate and the rotating seat. The helical springs provide elastic support for the lifting plate, so that the cutting disc can be separated from the composite plate before cutting the tunnel steel composite plate on the fixed seat.
[0007] Preferably, the ends of the two slide rods are fixedly connected by a cross plate, which fixes the ends of the two slide rods together to improve the stability of the two slide rods.
[0008] Preferably, a bearing seat is fixedly installed on the upper surface of the lifting plate near the front surface, and the rotating shaft passes through the bearing seat. The bearing inside the bearing seat is sleeved on the outer surface of the rotating shaft, which supports the rotating shaft and makes the rotating shaft rotate stably.
[0009] Preferably, a protective net is fixedly installed inside the air inlet duct near the front surface. The protective net can prevent large impurities from entering the air inlet duct and causing damage to the fan blades, and also prevent accidental contact with the fan blades and mechanical injury.
[0010] Preferably, a handle is fixedly installed on the upper surface of the lifting plate near the rear surface of the protective cover, and the lifting plate is raised and lowered by the handle.
[0011] Preferably, support legs are fixedly connected to the lower surface of the fixed base near the four corners, and the support legs provide fixed support for the fixed base.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a fixed base, a rotating base, a lifting base, a sliding rod, a sliding sleeve, a rotating motor, a protective cover, an air inlet pipe, fan blades, a rotating shaft, and a safety coupling, achieves the effect of cooling the cutting disc during the cutting of tunnel steel composite plates, thereby extending the service life of the cutting disc and improving the cutting quality. The tunnel steel composite plate is placed on the fixed base, and the cutting angle of the cutting disc relative to the composite plate is adjusted by rotating the rotating base. The output end of the rotating motor drives the cutting disc and fan blades to rotate through the safety coupling and the rotating shaft. The lifting plate descends and completes the cutting of the composite plate through the cutting disc. During the cutting process, the outside air is drawn into the protective cover through the air inlet pipe, which dissipates heat and cools the cutting disc, thereby reducing the temperature of the cutting disc during cutting and extending the service life of the cutting disc.

Detailed Implementation
[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

A rotating base 2 is rotatably mounted on the upper surface of the fixed base 1. The rotating base 2 and the fixed base 1 are rotatably connected by bearings. Slide rods 5 are symmetrically fixedly connected on both sides of the upper surface of the rotating base 2. The ends of the two slide rods 5 are fixedly connected by a horizontal plate 7. The horizontal plate 7 fixes the ends of the two slide rods 5 together to improve the stability of the two slide rods 5. Sliding sleeves 18 are fixedly mounted on both sides of the upper surface of the lifting plate 4, and the two slide rods 5 pass through the two sliding sleeves 18 respectively. A helical spring 3 is spirally wound on the outer surface of the two slide rods 5 between the lifting plate 4 and the rotating base 2. The helical spring 3 provides elastic support for the lifting plate 4.
[0023] A protective cover 9 is fixedly installed on the front surface of the lifting plate 4, and an air inlet pipe 10 is fixedly installed on the front surface of the protective cover 9. A rotating motor 6 is fixedly installed on the upper surface of the lifting plate 4 near the rear surface. The output end of the rotating motor 6 is fixedly connected to a rotating shaft 17 through a safety coupling 13. The safety coupling 13 has an overload protection function to prevent the rotating motor 6 from being damaged due to overload jamming during the rotation of the rotating shaft 17. A bearing seat 14 is fixedly installed on the upper surface of the lifting plate 4 near the front surface, and the rotating shaft 17 passes through the bearing seat 14. The bearing inside the bearing seat 14 is sleeved on the outer surface of the rotating shaft 17, which supports the rotating shaft 17 and makes the rotating shaft 17 rotate stably.
[0024] A cutting disc 16 and a fan blade 15 are fixedly installed on the outer surface of the rotating shaft 17. The cutting disc 16 and the fan blade 15 are located inside the protective cover 9 and the air inlet pipe 10, respectively. The protective cover 9 is hollow inside and open at the bottom. Part of the cutting disc 16 extends from the bottom opening to the outside of the protective cover 9. The part of the cutting disc 16 located outside the protective cover 9 cuts the steel composite plate for the tunnel. The air inlet pipe 10 and the inside of the protective cover 9 are connected. When the fan blade 15 rotates, outside air is drawn into the inside of the protective cover 9 from the air inlet pipe 10, which plays a role in heat dissipation and cooling of the cutting disc 16. A protective net 11 is fixedly installed inside the air inlet pipe 10 near the front surface. The protective net 11 can prevent large impurities from entering the air inlet pipe 10 and causing damage to the fan blade 15. It can also prevent accidental contact with the fan blade 15 and mechanical injury.
