Description
Technical Field
[0001] This application relates to the technical field of industrial equipment testing, and in particular to a multifunctional scraper chain ring testing ruler. Background Technology
[0002] As a core material conveying equipment, the performance and reliability of the scraper chain links of the scraper conveyor directly affect production safety and efficiency. Under long-term high load and strong wear conditions, scraper chain links are prone to problems such as dimensional deviation, wear, and deformation. If they are not inspected and maintained in time, they may cause serious accidents such as chain breakage and machine shutdown.
[0003] The inspection of scraper chain links mainly relies on general measuring tools such as vernier calipers and micrometers, or dedicated single-function testing equipment. When using general tools such as vernier calipers and micrometers, operators need to have high professional skills and rich experience. The measurement process is cumbersome, inefficient, and requires multiple tools, making it difficult to meet the needs of rapid inspection in industrial settings.
[0004] Regarding the aforementioned technologies, the applicant believes that they suffer from drawbacks such as cumbersome processes, low efficiency, and the need for multiple tools. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides a multifunctional scraper chain ring detection ruler.
[0006] This application provides a multifunctional scraper chain ring inspection ruler, which adopts the following technical solution:
[0007] A multifunctional scraper chain ring measuring ruler includes a ruler plate. One side of the ruler plate is provided with a vertical ring outer width measuring section and a horizontal ring outer width measuring section. The vertical and horizontal ring outer width measuring sections are composed of two stepped rectangular grooves. The rectangular groove of the vertical ring outer width measuring section is located inside the rectangular groove of the horizontal ring outer width measuring section. The width of the rectangular groove of the vertical ring outer width measuring section is smaller than the width of the rectangular groove of the horizontal ring outer width measuring section. Both the vertical and horizontal ring outer width measuring sections have rounded corners on both sides of their bottom ends. The vertical ring outer width measuring section is used to measure the outer width of the chain's vertical rings, and the horizontal ring outer width measuring section is used to measure the outer width of the chain's horizontal rings.
[0008] By adopting the above technical solution, the outer width detection section of the vertical ring and the outer width detection section of the horizontal ring adopt a stepped rectangular groove structure. The outer width of the two types of chain links can be measured in a targeted manner by means of the width difference. The rounded corner structure can better adapt to the arc transition part of the chain link, so that the detection ruler fits tightly with the surface of the chain link. The detection section is integrated into the same ruler plate, eliminating the need to carry multiple special tools, reducing equipment redundancy, and facilitating quick switching of measurement objects on site.
[0009] Preferably, the rectangular block portion at one end of the flat ring outer width detection part is the vertical ring inner width detection part, and the bottom ends of the rectangular block of the vertical ring inner width detection part have rounded corner structures. The vertical ring inner width detection part is used to measure the inner width of the chain vertical ring.
[0010] By adopting the above technical solution, the outer width detection part of the flat ring, the outer width detection part of the vertical ring, and the inner width detection part of the vertical ring are sequentially set on the same side of the ruler plate. The three detection functions are integrated in a limited space through the stepped structure. The bottom of the rectangular block of the inner width detection part of the vertical ring adopts a rounded corner design, which can accurately match the arc transition area of the inner hole of the vertical ring and avoid measurement deviation caused by the right angle edge not being able to be fully embedded in the inner hole.
[0011] Preferably, the diameter detection unit is composed of two stepped rectangular grooves, the outer rectangular groove of the diameter detection unit represents the maximum standard value of the diameter, and the inner rectangular groove of the diameter detection unit represents the minimum standard value of the diameter. The diameter detection unit is used to measure the diameter of the chain.
[0012] By adopting the above technical solution, the width of the outer rectangular groove corresponds to the maximum allowable value of the chain diameter, and the inner rectangular groove corresponds to the minimum allowable value. The outer groove can be embedded but the inner groove cannot be embedded, so that the diameter is within the qualified range.
[0013] Preferably, a ring width detection part is provided on the opposite side of the upright ring outer width detection part and the flat ring outer width detection part on the ruler plate. The ring width detection part is composed of a single rectangular groove. The width of the ring width detection part is the maximum standard value of the ring width. The bottom ends of the rectangular groove of the ring width detection part have rounded corner structures. The ring width detection part is used to measure the width of the ring.
[0014] By adopting the above technical solution, the ring width detection unit adopts a single rectangular groove design, and the groove width is set to the maximum standard value of the ring width. It can quickly detect whether the ring width exceeds the standard. It complements the vertical ring outer width detection unit and the horizontal ring outer width detection unit, and completes the measurement of multiple key dimension parameters of chain rings on the same ruler plate. There is no need to equip it with additional special measuring tools, which improves the integration and practicality of the detection ruler.
[0015] Preferably, a flat ring inner width detection part is provided on the side of the ring width detection part away from the diameter detection part. The flat ring inner width detection part is a rectangular block. The width of the flat ring inner width detection part is the minimum standard value of the flat ring inner width. The bottom side of the flat ring inner width detection part has a rounded corner structure. The flat ring inner width detection part is used to measure the inner width of the chain flat ring.
[0016] By adopting the above technical solution, the inner width detection part of the flat ring is set on one side of the ring width detection part and reasonably arranged with other detection parts on the same ruler. A rectangular block is used as the inner width detection part of the flat ring, and its width is set as the minimum standard value of the inner width of the flat ring. When the rectangular block can be smoothly inserted into the inner hole of the flat ring, it means that the inner width of the flat ring is greater than or equal to the minimum standard value and is within the qualified range.
[0017] Preferably, the ring width detection part has a rectangular notch on the ruler plate on the side near the diameter detection part, the middle part of the ring width detection part on the side near the diameter detection part has a rounded corner structure, the bottom of the rectangular notch on the ruler plate on the side near the diameter detection part of the ring width detection part has a rounded corner structure, the inner width detection part of the flat ring has a rectangular notch on the ruler plate on the side away from the diameter detection part, and the bottom of the rectangular notch on the side away from the diameter detection part of the flat ring has a rounded corner structure.
[0018] Preferably, the rectangular notch on the side away from the diameter detection part has a rounded corner structure at the transition connection with the adjacent side, and a hole concentric with the rounded corner structure is provided at the transition connection with the adjacent side, the diameter of the hole being smaller than the rounded corner structure at the transition connection with the adjacent side.
[0019] Preferably, the end of the inner width detection section away from the diameter detection section and the end of the outer side of the ring width detection section near the diameter detection section are configured as chain pitch detection sections. The outer sides of both ends are the minimum standard value of the pitch, and the inner sides of both ends are the maximum standard value of the pitch. The chain pitch detection section is used to measure the chain pitch.
[0020] By adopting the above technical solution, the pitch detection unit does not need an independent structure. It directly uses the end of the inner width detection unit away from the diameter detection unit and the end of the stepped rectangular block of the ring width detection unit near the diameter detection unit as the measurement reference. The pitch tolerance range is formed by the minimum standard value on the outer side and the maximum standard value on the inner side of both ends. Pitch detection is achieved by reusing the geometric features of the ends. No additional tools are required, which improves the detection efficiency.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] The vertical ring outer width detection section and the horizontal ring outer width detection section adopt a stepped rectangular groove structure. By using the width difference, the outer width of the two types of chain links can be measured in a targeted manner. The rounded corner structure can better adapt to the arc transition part of the chain link, so that the detection ruler fits tightly with the surface of the chain link. The detection section is integrated into the same ruler plate, eliminating the need to carry multiple special tools, reducing equipment redundancy, and facilitating quick switching of measurement objects on site.
[0023] The pitch detection unit does not require a separate structure. It directly utilizes the end of the inner width detection unit away from the diameter detection unit and the end of the stepped rectangular block of the ring width detection unit near the diameter detection unit as the measurement reference. The pitch tolerance range is formed by the minimum standard value on the outer side and the maximum standard value on the inner side of both ends. Pitch detection is achieved by reusing the geometric features of the ends, without the need for additional tools, thus improving detection efficiency. Attached Figure Description
