[0014] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below according to specific implementation modes and in combination with the accompanying drawings.

[0015] Figure 1 A schematic diagram of the structure of a device for assisting in lifting the upper header of a high-pressure water descaling box provided in an embodiment of the present application. The device comprises a descaling box 1, an upper frame 2, a lifting screw 3, an upper header 4, and a lifting drive assembly. The lifting drive assembly can drive the upper frame 2 to lift quickly, thereby driving the upper header 4 to lift quickly, and preventing the upper header 4 from being damaged by the slab.

[0016] For details, see Figure 1 , the upper frame 2 is installed above the descaling box 1. One end of the lifting screw 3 is connected to the descaling box 1, and the other end is connected to the upper frame 2. The lower ends of the two upper headers 4 extend into the descaling box 1, and the upper ends of the two upper headers 4 are fixedly connected to the upper frame 2 through telescopic joints.

[0017] The upper frame 2 can be driven to rise or fall slowly by the driving of the lifting screw 3, thereby driving the upper header 4 to rise or fall through the telescopic joint, thereby avoiding the collision between the upper header 4 and the slab.

[0018] It can be understood that the lifting screw 3 needs to drive the screw rod to rotate when driving the upper frame 2 to rise and fall, so the rising or falling speed is slow. Therefore, the embodiment of the present application improves the driving of the upper header 4 to rise and fall by setting a lifting drive component.

[0019] Among them, in this embodiment, the lifting drive assembly adopts a hydraulic cylinder 5. The main body of the hydraulic cylinder 5 is fixedly installed on the upper end of the descaling box 1, and the end of the piston rod of the hydraulic cylinder 5 is fixedly connected to the upper frame 2. The upper frame 2 is driven to rise by the hydraulic cylinder 5, so that the purpose of quickly rising the upper frame 2 can be achieved, thereby preventing the upper header 4 from being damaged by the slab due to untimely rising.

[0020] Preferably, two hydraulic cylinders 5 are provided. Figure 1 There are two upper headers 4, and the two upper headers 4 are symmetrically arranged on both sides of the lifting screw 3. Two hydraulic cylinders 5 are symmetrically arranged on both sides of the lifting screw 3 and are located outside the two upper headers 4. The two hydraulic cylinders 5 are respectively arranged on both sides of the length direction of the upper frame 2, and can drive the upper frame 2 to rise by operating at the same time, so as to achieve the purpose of quickly lifting the upper header 4.

[0021] In addition, a protective sleeve is also provided on the outside of the piston rod of each hydraulic cylinder 5. One end of the protective sleeve is connected to the upper frame 2, and the other end of the protective sleeve is connected to the main body of the hydraulic cylinder 5, and the protective sleeve is retractable. When the piston rod of the hydraulic cylinder 5 is extended and retracted, the protective sleeve always covers the piston rod to protect the hydraulic cylinder 5.

[0022] Therefore, the technical solution of the present application drives the upper frame 2 to rise through the hydraulic cylinder 5, so as to achieve the purpose of rapid rising of the upper frame 2, thereby preventing the upper collecting pipe 4 from being damaged by the slab due to untimely rising, thereby ensuring the service life of the descaling device.

[0023] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
