[0019] 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.

[0020] In this embodiment, if Figure 1 As shown, the scraper conveyor scraper correction device includes a workbench 1, a mounting frame 2, a driving member 3 and a correction pressure head 4. The mounting frame 2 is arranged on the workbench 1. A limiting opening 5 is arranged on one side of the mounting frame 2. The limiting opening 5 is arranged on one side of the workbench 1 to limit the scraper (not shown in the figure) located on the workbench 1. The driving member 3 is arranged on the mounting frame 2 and is located above the workbench 1. The correction pressure head 4 is connected to the driving member 3, and the driving member 3 is used to drive the correction pressure head 4 to move along the height direction of the workbench 1 (Z direction in the figure).

[0021] For example, the driving member 3 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is connected to the mounting frame 2, the correction pressure head 4 is connected to the piston rod of the hydraulic cylinder, and the correction pressure head 4 is driven to move along the height direction of the workbench 1 by the extension and retraction of the piston rod.

[0022] When the scraper needs to be corrected, the scraper is placed on the workbench 1, and one end of the scraper is inserted into the limit opening 5. The scraper is limited by the limit opening 5, and then the driving member 3 is started. The correction pressure head 4 is driven downward by the driving member 3. The scraper is corrected by the pressure applied by the correction pressure head 4 to the scraper. No manual knocking is required, which can reduce labor intensity and is beneficial to improving the correction efficiency of the scraper.

[0023] In this embodiment, if Figure 1 As shown, the correction pressure head 4 includes a connecting portion 41 and a crimping portion 42. The connecting portion 41 has a first end and a second end in the height direction of the workbench 1. The first end of the connecting portion 41 is connected to the driving member 3. The crimping portion 42 is connected to the second end of the connecting portion 41.

[0024] Specifically, the correction pressure head 4 can be provided in plurality, and the lengths of the connecting parts 41 of the plurality of correction pressure heads 4 are different. The correction pressure head 4 with the connecting part 41 of the corresponding length can be selected as needed to be connected to the driving member 3, so that the stroke of the crimping part 42 can be changed, so that when correcting the scraper with different bending degrees, the stroke of the crimping part 42 is more conducive to improving the correction efficiency of the scraper. The crimping part 42 and the connecting part 41 can be integrally formed or separately formed. The separately formed connecting part 41 and the crimping part 42 are detachably connected, and the connecting part 41 can be provided in plurality, and the lengths of the plurality of connecting parts 41 are different. By connecting different connecting parts 41 and the crimping part 42, the total length of the correction pressure head 4 can also be changed, so that costs can be saved, and when the crimping part 42 is damaged, there is no need to replace the correction pressure head 4 as a whole.

[0025] The correction pressure head 4 includes a connecting portion 41 and a crimping portion 42. By providing the connecting portion 41 and the crimping portion 42, the connecting portion 41 and the crimping portion 42 can be respectively set to corresponding sizes as required, which is beneficial to saving costs.

[0026] In this embodiment, the height of the limiting opening 5 in the height direction of the workbench 1 is H, the thickness of the scraper is T, and 1T<H≤1.4T.

[0027] Specifically, the thickness of the scraper is the thickness determined when the scraper conveyor is produced, and its specific value will not be described in detail again.

[0028] For example, the height H of the limit opening 5 can be 1.1T, 1.2T, 1.3T or 1.4T, etc. If the height of the limit opening 5 is too small, it will make the scraper installation inconvenient or impossible to install. If the height of the limit opening 5 is too large, the scraper will easily shake, which is not conducive to correcting the scraper.

[0029] In this embodiment, the thickness of the scraper is set to 1T<H≤1.4T, which can facilitate the placement of the scraper into the limiting opening 5 and can limit the scraper more stably, which is conducive to making the correction head 4 more stable during the correction of the scraper.

[0030] In this embodiment, the length of the limiting opening 5 in the width direction of the workbench 1 matches the width of the scraper.

[0031] It can be understood that the length of the limit opening 5 in the width direction of the workbench 1 matches the width of the scraper, which can better limit the width direction of the scraper and prevent the scraper from being deflected in the limit opening 5, causing the correction head 4 to be unable to accurately correct the scraper.

[0032] In this embodiment, if Figure 1As shown, the support frame includes two side supports 21 and a top support 22. The two side supports 21 are arranged at intervals on the workbench 1, and at least one of the two side supports 21 is provided with a limiting opening 5. The top support 22 has a first end and a second end in the length direction of the workbench 1. The first end and the second end of the top support 22 are respectively connected to the two side supports 21, and the driving member 3 is arranged on the top support 22.

[0033] Specifically, the limiting opening 5 can be provided on the side support member 21 on one side, or the limiting opening 5 can be provided on the side support members 21 on both sides. When the limiting opening 5 is provided on the side support member 21 on one side, one end of the scraper is inserted into the limiting opening 5, and the other end is free. When the limiting opening 5 is provided on the side support members 21 on both sides, either end of the scraper can be inserted into the corresponding limiting opening 5.

[0034] For example, the first end and the second end of the top support member 22 are respectively welded to the side support members 21 on both sides. Of course, the top support member 22 and the side support member 21 can also be connected in other ways, which are not limited here.

[0035] It can be understood that by providing two side supports 21 to support the top support 22 and providing the drive on the top support 22, the installation of the drive member 3 can be facilitated, and a limit opening 5 can be provided on the side support 21 to limit the scraper, without the need for additional components to provide the limit opening 5, the structure is simple and compact, and cost is saved.

[0036] In this embodiment, if Figure 1 As shown, the scraper conveyor scraper correction device also includes a connecting frame 6, the connecting frame 6 is connected to the top support member 22, and the driving member 3 is arranged on the connecting frame 6.

[0037] Specifically, the connection frame 6 and the top support member 22 are detachably connected, which can facilitate the installation and removal of the connection frame 6.

[0038] When installing the driving member 3 , the driving member 3 may be installed on the connecting frame 6 in advance, and then the connecting frame 6 may be installed on the top supporting member 22 , which may facilitate the installation of the driving member 3 .

[0039] In this embodiment, if Figure 1 As shown, the connecting frame 6 includes a first mounting plate 61, a connecting rod 62 and a second mounting plate 63, and the first mounting plate 61 is connected to the top support member 22. The connecting rod 62 has a first end and a second end in the height direction of the workbench 1, the first end of the connecting rod 62 is connected to the first mounting plate 61, the second mounting plate 63 is arranged at the second end of the connecting rod 62, the driving member 3 is arranged on the top of the second mounting plate 63, and the telescopic end of the driving member 3 passes through the second mounting plate 63, and the correction pressure head 4 is located below the second mounting plate 63 and connected to the telescopic end of the driving member 3.

[0040] Specifically, a avoidance hole is provided on the second mounting plate 63 , and the telescopic end of the driving member 3 passes through the second mounting plate 63 through the avoidance hole.

[0041] For example, the connecting rod 62 can be one, two, three or four, etc. When a plurality of connecting rods 62 are provided, the plurality of connecting rods 62 are spaced and distributed between the first mounting plate 61 and the second mounting plate 63. The plurality of connecting rods 62 can make the connection between the first mounting plate 61 and the second mounting plate 63 more stable.

[0042] It can be understood that the first mounting plate 61 and the second mounting plate 63 are spaced apart from each other in the upper and lower parts and are connected by a connecting rod 62, and a space for accommodating the driving member 3 is formed between the first mounting plate 61, the second mounting plate 63 and the connecting rod 62. The installation is connected by the first mounting plate 61 and the top support member 22, which can make the connection between the connecting frame 6 and the top support member 22 more convenient.

[0043] In this embodiment, the connecting rod 62 is a screw rod, and the screw rod passes through the second mounting plate 63 .

[0044] Specifically, the top end of the connecting rod 62 is fixedly connected to the first mounting plate 61, for example, the top end of the connecting rod 62 is welded to the first mounting plate 61, the bottom end of the connecting rod 62 is provided with a thread, the bottom end of the connecting rod 62 passes through the second mounting plate 63, and a nut is sleeved on the connecting rod 62 to fix the second mounting plate 63. The second mounting plate 63 can be moved along the connecting rod 62 by rotating the nut, so that the distance between the second mounting plate 63 and the first mounting plate 61 can be changed, which is convenient for installing drive members 3 of different specifications and can change the stroke of the drive member 3.

[0045] In this embodiment, the scraper conveyor scraper correction device further includes a protective pad (not shown in the figure), which is arranged at the end of the correction pressure head 4 away from the driving member 3.

[0046] For example, the protective pad can be a rubber protective pad. Of course, the protective pad can also be set to other materials, which is not limited here.

[0047] It can be understood that by providing a protective pad on the side of the correcting pressure head 4 facing the workbench 1, the scraper can be protected when the correcting pressure head 4 applies pressure to the scraper, thereby reducing damage to the scraper caused by the pressure.

[0048] In this embodiment, the scraper conveyor scraper correction device also includes a correction pad (not shown in the figure), which is arranged on the workbench 1 and opposite to the correction head 4. The correction head 4 is provided with a first correction portion on the side facing the correction pad, and the correction pad is provided with a second correction portion on the side facing the correction head 4. When the correction head 4 is crimped onto the correction pad, a correction cavity matching the shape of the scraper is formed between the correction pad and the correction head 4.

[0049] It can be understood that by setting a correction pad, setting a first correction part on the top of the correction pad, and setting a second correction part on the bottom of the correction head 4, when the correction head 4 is crimped onto the correction pad, a correction cavity matching the shape of the scraper is formed between the correction pad and the correction head 4. The shapes of the first correction part and the second correction part can be set according to the shape of the scraper, and different shapes of correction heads 4 and correction pads can be set for scrapers of different shapes, thereby expanding the scope of application of the scraper correction device of the scraper conveyor.
