[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0022] like Figure 1 As shown, the scraper correction device 100 of the embodiment of the utility model comprises a fixed shell 1, a hammer 2 and a driving member 3. The fixed shell 1 is in a preset direction (for example Figure 1 A working platform 13 is provided at one end of the fixed shell 1 (in the up and down direction), and the working platform 13 is used to place the scraper. The hammer 2 is movably arranged on the fixed shell 1 and has a calibration position and a disengagement position. In the calibration position, the hammer 2 abuts against the scraper, and in the disengagement position, the hammer 2 is disengaged from the scraper. The driving member 3 is arranged on the fixed shell 1, and the driving member 3 is connected to the hammer 2 to drive the hammer 2 to move between the calibration position and the disengagement position.

[0023] When the scraper correction device 100 of the embodiment of the utility model is used, the scraper is placed on the working platform 13, and then the driving member 3 drives the hammer member 2 to move from the disengaged position to the correction position. In the correction position, the hammer member 2 applies force to the bent scraper, and the bent scraper is deformed by the force, so that the bent scraper tends to be flat, so that the scraper returns to its normal shape. After the driving member 3 drives the hammer member 2 to move from the correction position to the disengaged position, the hammer member 2 is separated from the scraper. If the deformation of the bent scraper is large, the driving member 3 drives the hammer member 2 to move back and forth between the correction position and the disengaged position for multiple times, and the hammer member 2 hammers the scraper multiple times to restore the scraper to its normal shape.

[0024] The scraper correction device 100 of the utility model embodiment has a simple structure. The fixed shell 1 provides stable support for the correction device. The driving member 3 drives the hammer member 2 to hammer the bent scraper back and forth for multiple times to restore the scraper to its normal shape, thereby completing the correction of the shape of the bent scraper. No personnel are required to knock, which reduces the degree of personnel participation, improves the efficiency of correcting the bent scraper, and improves the safety of the correction operation.

[0025] In order to make the solution of the present application easier to understand, the preset direction is taken as an example to illustrate that the preset direction is the same as the up and down direction. Figure 1 shown.

[0026] The scraper correction device 100 of the embodiment of the utility model comprises a fixed shell 1, a fixed base 4, a hammer member 2 and a driving member 3.

[0027] The fixed shell 1 is provided with a working platform 13 at one end (lower end) in the preset direction, and the working platform 13 is used to place the scraper. The fixed shell 1 has an installation cavity 11, and the hammer 2 and the driving member 3 are both located in the installation cavity 11. The fixed shell 1 is provided with a fixing port 12 at this end, and the fixing port 12 is connected to the installation cavity 11, and the fixing port 12 is opposite to the working platform 13, and the fixing port 12 is used to place the scraper. When the scraper is corrected, the scraper is placed from the fixing port 12 to the working platform 13. The fixing port 12 can limit the position of the scraper, so that the scraper can be accurately placed on the working platform 13 and remain stable on the working platform 13, so as to avoid the scraper from jumping when being hammered by the hammer 2. At the same time, the fixing port 12 also limits the range of activities of personnel, prevents the personnel's hands from reaching into the installation cavity 11 of the fixed shell 1, and prevents the hammer 2 from accidentally injuring people during operation, thereby improving the operation safety of the scraper correction device 100 of the embodiment of the utility model.

[0028] Specifically, according to the scraper of different sizes, the size of the fixing opening 12 suitable for the scraper can be selected to ensure that the scraper can pass through the fixing opening 12, and the fixing opening 12 can fix the scraper, ensure the stability of the position of the scraper, and ensure the contact and hammering between the hammer and the scraper.

[0029] Specifically, the fixed shell 1 is welded by I-beams, and a steel plate is provided at the lower end of the fixed shell 1. The steel plate forms a working platform 13 of the fixed shell 1. The fixed shell 1 has good anti-deformation ability.

[0030] The hammer 2 is movably arranged on the fixed shell 1 and has a calibration position and a disengagement position. In the calibration position, the hammer 2 abuts against the scraper, and in the disengagement position, the hammer 2 is disengaged from the scraper. The driving member 3 is arranged on the fixed shell 1, and the driving member 3 is connected to the hammer 2 to drive the hammer 2 to move between the calibration position and the disengagement position.

[0031] The hammer member 2 includes a connecting rod 21 and a pad 22, one end (upper end) of the connecting rod 21 is connected to the driving member 3, and the other end (lower end) of the connecting rod 21 is connected to the pad 22, and the projection surface of the pad 22 on the working platform 13 along the preset direction covers the projection surface of the other end of the connecting rod 21 on the working platform 13 along the preset direction, that is, the area of ​​the lower side surface of the pad 22 is larger than the area of ​​the lower side surface of the connecting rod 21, the contact area between the pad 22 and the scraper is larger, and the force application surface of the hammer member 2 on the scraper is large, which is beneficial to improving the efficiency of the hammer member 2 applying force to the scraper to deform it, and is beneficial to improving the efficiency of the scraper correction device 100 of the embodiment of the utility model for the scraper correction operation.

[0032] In some embodiments, the backing plate 22 is detachably connected to the other end of the connecting rod 21.

[0033] The pad 22 is detachably connected to the connecting rod 21, so that the pad 22 is easy to replace, so that the size of the pad 22 of the scraper correction device 100 can be adjusted to adapt to scrapers of different sizes and specifications, thereby ensuring the hammering efficiency and correction effect of the hammer member 2 on the scraper.

[0034] In some embodiments, the driving member 3 is a telescopic member, and the telescopic member has a fixed end and a movable end. The fixed end is arranged on the other end (upper end) of the fixed shell 1 in the preset direction, and the movable end is connected to the hammer member 2. The extension direction of the telescopic member is the same as the preset direction. When the telescopic member is extended and retracted, its movable end moves accordingly, thereby driving the hammer member 2 to move up and down, and realizing the movement of the hammer member 2 between the correction position and the disengagement position. The driving member 3 of the scraper correction device 100 of the utility model embodiment adopts a telescopic member, and the telescopic stroke of the telescopic member is the same as the moving stroke direction of the hammer member 2, which is conducive to the transmission of motion. At the same time, the telescopic member is arranged above the hammer member 2. During the process of the hammer member 2 hammering the scraper, the telescopic member can also provide support for the hammer member 2 to avoid the rebound of the hammer member 2 during the collision between the hammer member 2 and the scraper, thereby ensuring the movement of the hammer member 2 and the stability of the hammering.

[0035] In some embodiments, the telescopic member is a hydraulic cylinder. The use of a hydraulic cylinder as the driving member 3 exerts a large force on the scraper, thereby achieving a good correction effect and being able to adapt to the correction of scrapers with different deformation degrees, thereby improving the practicality of the scraper correction device 100 of the embodiment of the utility model.

[0036] Specifically, the stroke of the hydraulic cylinder is 8cm, and the pulling force generated is 20KN. The short stroke of the hydraulic cylinder can realize the correction of scrapers with large deformation degrees and meet the correction needs of scrapers with various curvatures.
