Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyor detection, in particular to a device for detecting parallelism of a middle groove of a scraper conveyor. Background Art

[0002] The middle trough is mainly used in scraper conveyors in coal mines and is the body of the scraper conveyor. Scraper conveyors at home and abroad are constantly developing in the direction of large capacity, long distance, high power, long life and high reliability. The quality of the middle trough accounts for more than 70% of the total quality of the scraper conveyor. Therefore, the product quality and service life of the middle trough are important indicators for measuring the life of the whole machine. The middle trough is welded by the middle plate, trough side, bottom plate, panel, rack rail seat and other parts. Therefore, the measurement of the welding quality of the middle trough and the dimensional deformation after welding is particularly important.

[0003] At present, the key technical difficulty of the middle trough of the scraper conveyor is that the parallelism between the middle plate of the middle trough and the panel is required to be ≤1.5 mm. If the tolerance is exceeded, the cable trough assembled on the panel will be deformed, and the next section of the cable trough cannot be installed with the previous cable trough. However, since the width of the middle trough of this structure is greater than 1200 mm, the specifications are large, the welding process is complex, and the welding amount is large, the middle plate and the panel will undergo welding deformation to varying degrees after welding, and the welding deformation is irregular. Due to the structural limitations of the middle trough, it is impossible to directly or indirectly measure the parallelism between the middle plate of the middle trough and the panel, which makes it difficult to correct the middle plate and the panel, and the efficiency is low. It is impossible to ensure the technical requirement of parallelism between the middle plate of the middle trough and the panel of ≤1.5 mm, and thus it is impossible to ensure the product quality of the middle trough, which reduces production efficiency. Summary of the invention

[0025] The technical scheme and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0026] Please see Figures 1 to 3A device 200 for detecting parallelism of a middle groove of a scraper conveyor includes a long measuring rod 210 and a short measuring rod 220. The long measuring rod 210 is vertically connected to the short measuring rod 220 so that the short measuring rod 220 can be placed on a middle plate 110 of the middle groove 100 of the scraper conveyor, and cooperates with the long measuring rod 210 to detect the parallelism between the middle plate 110 and the panel 120 of the middle groove 100 of the scraper conveyor.

[0027] Compared with the prior art, the beneficial effects of the utility model are:

[0028] By placing the short measuring rod on the middle plate of the scraper conveyor middle slot, the part of the long measuring rod is located above the panel, and measuring the distance between the long measuring rod and the panel, the parallelism between the middle plate and the panel of the scraper conveyor middle slot is determined. The parallelism detection device for the scraper conveyor middle slot of the utility model can quickly and conveniently detect the parallelism tolerance between the middle plate and the panel, and provide data support for the correction welding deformation of the scraper conveyor middle slot, thereby ensuring product quality and improving production efficiency.

[0029] Among them, the measuring long rod 210 and the measuring short rod 220 are vertically connected, and can be connected by welding, bolting, or other connection methods, which are not limited here. After the connection is completed, the measuring long rod 210 and the measuring short rod 220 need to be processed to ensure that the detection device 200 itself is placed on the plane and is parallel to the plane, so as to ensure that the detection device 200 itself is parallel, and then the detection device 200 can be used to detect the parallelism of the middle groove of the scraper conveyor. Among them, detecting the parallelism of the middle groove of the scraper conveyor is actually measuring the parallelism between the middle plate and the panel of the scraper conveyor.

[0030] When the scraper conveyor middle groove parallelism detection device 200 is used for detection, the measuring short rod 220 is placed on the middle plate 110 for detection. Since the width direction of the middle groove is flat, the measuring short rod 220 can stand firmly on the middle plate 110, so no additional fixing device is required to fix the measuring short rod 220; and in order to enhance the stability of the measuring short rod 220 during measurement, the measuring short rod 220 can also be additionally fixed, which is not limited here. After the measuring short rod 220 is placed on the middle plate 110, part of the measuring long rod 210 will be located above the panel 120, and the parallelism between the middle plate 110 and the panel 120 is determined by detecting the distance between the measuring long rod 210 and the panel 120. Specifically, when testing the parallelism of the middle groove, the measuring short rod 220 is placed on the middle plate 110, and the measuring long rod 210 is located above the panel 120, and the distance between the measuring long rod 210 and the panel 120 is measured. After the measurement, the measuring short rod 220 is placed at other positions of the middle plate 110, and the distance between the measuring long rod 210 and the panel 120 at the corresponding position is continued to be measured. Similarly, multiple positions of the middle plate 110 are tested, so as to determine the parallelism between the middle plate 110 and the panel 120 based on the difference between the measurement results of multiple positions. For example, the measuring short rod 220 is placed at the front position of the middle plate 110, and the distance between the measuring long rod 210 and the panel 120 is measured to be 30 mm. The measuring short rod 220 is placed in the middle position of the middle plate 110, and the distance between the measuring long rod 210 and the panel 120 is measured to be 31 mm. The difference between the two is 1 mm, that is, the measured parallelism between the middle plate and the panel of the middle groove of the scraper conveyor is 1 mm, and is less than 1.5 mm, indicating that the parallelism between the middle plate and the panel meets the requirement; if the difference is greater than 1.5 mm, it indicates that the parallelism between the middle plate and the panel does not meet the requirement, and the middle groove needs to be corrected.

[0031] When measuring the distance between the measuring rod 210 and the panel 120, the scraper conveyor middle groove parallelism detection device 200 can only measure the distance between the end of the measuring rod 210 and the end of the panel 120, and then compare it with the distance at the end of the panel at other positions; it can also measure the distances at multiple positions in the width direction of the panel 120 to determine whether the panel 120 is deformed in the width direction. That is, the scraper conveyor middle groove parallelism detection device 200 can be used in multiple groups to detect the parallelism of the middle groove in the length direction, width direction, and different points.

[0032] In some embodiments, the scraper conveyor middle groove parallelism detection device 200 needs to center and align the middle groove 100 before detection. Specifically, the middle groove 100 is centered during processing and aligned within the same range of spacing on both sides, wherein the range can be adjusted according to the different groove widths of the middle groove 100. For example, when the groove width is 800 mm, the spacing range can be about 500 mm; when the groove width is 1 meter, the spacing range can be about 800 mm. The scraper conveyor middle groove detection device 200 measures the parallelism between the middle plate 110 and the panel 120 within the range of the middle groove alignment during detection.

[0033] Furthermore, the scraper conveyor middle groove parallelism detection device 200 further includes a support rib 240, so as to fasten the measuring long rod 210 and the measuring short rod 220 through the support rib 240. When the measuring long rod 210 and the measuring short rod 220 are connected by welding, in order to enhance the stability of the connection between the measuring long rod 210 and the measuring short rod 220, the measuring long rod 210 and the measuring short rod 220 can be fastened through the support rib 240.

[0034] Further, the connection position between the short measuring rod 220 and the long measuring rod 210 is close to the right end of the long measuring rod 210, so that when the short measuring rod 220 is placed on the middle plate 110, the left end of the long measuring rod 210 is located above the panel 120, and the parallelism between the middle plate 110 and the panel 120 is determined by measuring the distance between the left end of the long measuring rod 210 and the panel 120. When the short measuring rod 220 is placed on the middle plate 110, since the short measuring rod 220 is connected close to the right end of the long measuring rod 210, it can be ensured that the left end of the long measuring rod falls above the panel 120, so that the parallelism between the middle plate and the panel is determined by measuring the distance between the long measuring rod and the panel, wherein a square ruler can be used to measure the distance between the long measuring rod and the panel.

[0035] Further, the length of the measuring rod 210 is recorded as the first length, and the distance between the right end of the middle plate 110 and the left end of the panel 120 is recorded as the second length, wherein the first length is greater than or equal to the second length, so that a portion of the measuring rod 210 is located above the panel 120, and the parallelism between the middle plate 110 and the panel 120 is determined by measuring the distance between the measuring rod 210 and the panel 120. In order to adapt to the middle grooves of different sizes, the measuring rod 210 can be designed according to the sizes of the middle plate and the panel of the middle groove, that is, as long as the length of the measuring rod 210 is greater than or equal to the sum of the widths of the middle plate and the panel, when the measuring short rod 220 is placed on the middle plate 110, a portion of the measuring rod 210 is located above the panel 220.

[0036] For further information, see Figure 4, the height between the middle plate 110 and the panel 120 is A, and the height of the measuring short rod 220 is B, wherein B is greater than A, so as to ensure the accuracy of measuring the distance between the measuring long rod 210 and the panel 120. Specifically, after the measuring long rod 210 and the measuring short rod 220 are vertically connected, the lower end surfaces of the measuring long rod 210 and the measuring short rod 220 need to be processed to ensure that the height B of the measuring short rod 220 is greater than the height A between the middle plate 110 and the panel 120, so as to ensure that the detection device 200 can perform detection normally.

[0037] Furthermore, the difference between B and A is H, so that the distance between the measuring long rod 210 and the panel 120 is measured, and the parallelism between the middle plate 110 and the panel 120 is determined according to the difference between the distance and H. Among them, H should be set larger, that is, the difference between the height B of the measuring short rod 220 and the height between the middle plate 110 and the panel 120 should be large, so as to facilitate the measurement of the distance between the measuring long rod 210 and the panel 120 and ensure the accuracy of the distance measurement. When the scraper conveyor middle trough detection device 200 is performing detection, H can be used as a theoretical value as a reference, and the actual measured distance between the measuring long rod 210 and the panel 120 is the measured value, and the parallelism tolerance value between the middle plate and the panel is the difference between the measured value and the theoretical value, and then the parallelism between the middle plate and the panel is determined by comparing the difference between the parallelism tolerance values ​​of multiple positions. For example, H is set to 35, that is, the theoretical value is 35, the measuring short rod 220 is placed at the front section of the middle plate, and the distance between the measuring long rod 210 and the panel 120 is measured to be 35, that is, the measured value is 35, then the parallelism tolerance value of the middle plate and the panel at this position is 0; the measuring short rod 220 is placed at the middle position of the middle plate, and the distance between the measuring long rod 210 and the panel 120 is measured to be 36, then the parallelism tolerance value of the middle plate and the panel at this position is 1; the measuring short rod 220 is placed at the rear section of the middle plate, and the distance between the measuring long rod 210 and the panel 120 is measured to be 36, then the parallelism tolerance value of the middle plate and the panel at this position is 1. The spacing between the panels 120 is 31, and the parallelism tolerance value of the middle plate and the panel at this position is 4; among them, the difference between the parallelism tolerance value of the front position and the parallelism tolerance value of the middle position is 1, which is less than 1.5, which can indicate that the parallelism of the middle plate and the panel from the front position to the middle position has met the requirement; the difference between the parallelism tolerance value of the rear position and the parallelism tolerance value of the middle position is 3, which is greater than 1.5, which can indicate that the parallelism of the middle plate and the panel from the middle position to the rear position has not met the requirement, and this section of the panel needs to be corrected.

[0038] Furthermore, when it is detected that the parallelism of the middle groove does not meet the parallelism requirement, the middle groove needs to be corrected, wherein H can be used as a reference to determine whether the panel 120 is warped upward or pulled downward relative to the middle plate 110. For example, H is 35, the parallelism tolerance value of the middle position is 36, and the parallelism tolerance value of the rear position is 31. The difference between the two is 3, which is greater than 1.5. It can be explained that the parallelism of the middle plate and the middle position to the rear position of the panel does not meet the requirement, and the panel of this section needs to be corrected. Among them, the parallelism tolerance value of the middle position is greater than H, indicating that the panel at the middle position is pulled downward relative to the middle plate, and it needs to be corrected upward; the parallelism tolerance value of the rear position is less than H, indicating that the panel at the rear position is warped upward relative to the middle plate, and it needs to be corrected downward.

[0039] In some embodiments, the number of the short measuring rod 220 may be one, and the short measuring rod 220 may be connected to the middle of the long measuring rod 210, so that the short measuring rod 220 can maintain balance and stand stably on the middle plate 110 when placed on the middle plate 110. When the short measuring rod 220 is placed on the middle plate 110, it is necessary to ensure that part of the long measuring rod 210 falls above the panel 120, wherein the left end of the long measuring rod 210 may be flush with the left end of the panel 120, or may extend slightly beyond the left end of the panel 120, as long as the distance between the long measuring rod and the panel can be measured, which is not limited here. The number of the short measuring rod 220 may also be multiple.

[0040] Furthermore, the measuring short rod 220 includes a first measuring short rod 221 and a second measuring short rod 222. The first measuring short rod 221 is connected to a position close to the right end of the measuring long rod 210, and the second measuring short rod 222 is connected to a position close to the middle of the measuring long rod 210. The distance between the first measuring short rod 221 and the second measuring short rod 222 is less than the width of the middle plate 110 and greater than half of the width of the middle plate 110, so that the scraper conveyor middle groove parallelism detection device 200 can stand stably on the middle plate 110, ensuring the stability of the scraper conveyor middle groove parallelism detection device during the detection process.

[0041] For further information, see Figure 5The scraper conveyor middle groove parallelism detection device 200 also includes a supporting side rod 230, which is installed on the right side of the first measuring short rod 221 and extends toward the right groove side of the middle groove. The upper surface of the supporting side rod 230 and the upper surface of the right groove side are located in the same plane; the supporting side rod 230 is parallel to the measuring long rod 210, and the length of the supporting side rod 230 is the same as the distance between the first measuring short rod 221 and the right groove side of the middle groove. Therefore, when the first measuring short rod 221 and the second measuring short rod 222 are placed on the middle plate 110, on the one hand, the scraper conveyor middle groove parallelism detection device 200 can be kept balanced and can be stably stood on the middle plate 110; on the other hand, since the upper surface of the supporting side rod 230 and the upper surface of the right groove side are located in the same plane, and the length of the supporting side rod 230 is the same as the distance between the first measuring short rod 221 and the right groove side of the middle groove, only when the supporting side rod 230 is kept parallel to the right groove side can the first measuring short rod 221 and the second measuring short rod 222 be placed on the middle plate 110, thereby ensuring that when the middle groove parallelism detection device 200 is placed on the middle plate 110, the measuring long rod 210 is parallel to the middle plate 110, thereby ensuring that the parallelism between the middle plate 110 and the panel 120 detected by the measuring long rod 210 is accurate.

[0042] Furthermore, both the long measuring rod 210 and the short measuring rod 220 are made of a hollow square tube.

[0043] For further information, see Figure 6 There are multiple scraper conveyor middle trough parallelism detection devices 200, so that multiple scraper conveyor middle trough parallelism detection devices 200 are placed at different positions of the middle plate 110 respectively, and the parallelism tolerance values ​​of different positions of the middle plate 110 are detected at the same time, and the parallelism between the middle plate 110 and the panel 120 is determined according to the parallelism tolerance value, thereby improving the detection efficiency of the scraper conveyor middle trough parallelism detection device 200, and further improving the production efficiency of the middle trough.
