Description

Technical Field

[0001] This utility model relates to the field of steam pipeline technology, specifically to a sliding pipe support offset measurement device. Background Technology

[0002] In steam pipeline engineering, sliding pipe supports allow the pipeline to move freely due to thermal expansion or contraction, while providing necessary support. However, due to various factors such as temperature changes and mechanical stress, the pipe supports may exhibit misalignment, meaning their position deviates from the ideal centerline. Accurately measuring this misalignment is crucial for ensuring the long-term stable operation of the pipeline system. Currently, when checking the misalignment of sliding pipe supports after installation during the construction phase, it is usually necessary to first accurately mark the center positions of both the support and the pipe support, and then determine the misalignment by measuring the distance between these two center points. This method is not only cumbersome but also prone to human error. Each time, the center position needs to be re-aligned and marked, increasing unnecessary workload. Furthermore, because it involves multiple manual interventions (such as manual marking), cumulative errors can easily occur, affecting the accuracy of the final measurement results. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a sliding tube support offset measurement device, which has the advantages of simple measurement operation, avoidance of repeated measurements, reduction of errors, and lower cost.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a sliding tube support offset measurement device, comprising: a main housing, a gear set assembled in the main housing, a rack set assembled on the upper and lower sides of the gear set and meshing with the gear set, a pointer set slidably assembled on the surface of the main housing, and a scale line set on the surface of the main housing and increasing outward from the center of the main housing as the zero point.

[0005] The pointer group includes: a first pointer and a second pointer; the end of the rack group that abuts against the edge of the main housing extends to the side opposite to the pointer group and is provided with a convex condition;

[0006] When the main housing is placed on the support, the rack assembly is pushed to move the convex condition axially to abut against both sides of the support, so that the zero point of the scale line is aligned with the center point of the support; the first pointer and the second pointer are slid to align with both sides of the support, and the value of the pointer assembly corresponding to the scale line is read.

[0007] The present invention further provides that the gear set includes: a middle gear aligned with the zero point of the scale line, a left gear disposed to the left of the middle gear, and a right gear disposed to the right of the middle gear.

[0008] The present invention further provides that the distance between the left gear and the middle gear is equal to the distance between the right gear and the middle gear.

[0009] The present invention further provides that the rack assembly includes: a first rack that meshes with the upper side of the middle gear and the right gear, and a second rack that meshes with the lower side of the middle gear and the left gear and has the same length as the first rack.

[0010] The present invention further includes a track groove inside the main housing for axial movement of the first rack and the second rack.

[0011] The present invention further includes a first convex strip with one end connected to the end of the first rack and the other end being a free end, and a second convex strip with one end connected to the end of the second rack and the other end being a free end.

[0012] The present invention further includes a clearance hole on the main housing for accommodating axial movement of the convex condition.

[0013] The present invention further provides that the main housing has a through groove for the sliding assembly of the pointer group.

[0014] The present invention further provides that the inner side of the groove is provided with an outwardly protruding part, and the pointer assembly is provided with a recessed part that cooperates with the protruding part.

[0015] The present invention further includes a blocking block at both ends of the groove to prevent the pointer assembly from sliding out.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In this utility model, the main shell is placed on the support, and the rack group is pushed to move axially, causing the convex condition at its end to contact and fit against both sides of the support. At this time, the zero point of the scale line is aligned with the center point of the support. Then, the first and second pointers are simultaneously aligned with both sides of the sliding support. Since the scale line increases from the center of the main shell as the zero point to both sides, the scale value corresponding to the right angle side of the first and second pointers is read according to the scale line position pointed to by the pointer group. The difference between these two scale values ​​is divided by two to obtain the offset of the sliding support, thus completing the measurement. In the above measurement process, no complicated tools or steps are required. Only the measurement device and adjustment components need to be placed to obtain the measurement result. The measurement operation is simple and does not require multiple measurements to increase unnecessary workload, greatly shortening the measurement time, improving work efficiency, and thus reducing labor costs. It can reduce measurement errors, and the accurate measurement result ensures that the sliding support can be stably held on the support after displacement according to the set expansion length when the steam pipeline is heated and expanded, ensuring the safe operation of the heating pipeline.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0025] This embodiment relates to a sliding tube support offset measurement device, referring to... Figures 1-3 It includes: main housing 1, gear set 2, rack set 3, pointer set 4, and scale line 5.

[0026] The main housing 1 is stamped from steel plate into a rectangular shape with an internal cavity. In other embodiments, the main housing 1 can also be stamped from other materials or into other shapes. The gear set 2 is assembled in the cavity within the main housing 1. The gear set 2 includes a bearing (not shown) fixedly mounted on the main housing 1 and a gear rotatably mounted on the bearing. Through meshing with the rack sets 3 on its upper and lower sides, the linear motion of the rack sets 3 moving axially within the main housing 1 is converted into the rotational motion of the gear set 2, further achieving efficient force transmission. Specifically, in this embodiment, both the bearing and the gear are coated with grease to reduce friction and wear during transmission, maintaining long-term reliability. It should be noted that during long-term use of the measuring device, regular checks and grease replenishment are necessary. In other embodiments, the bearing and gear can be coated with other lubricants. Furthermore, the end of the rack set 3 abutting the edge of the main housing 1 extends towards the pointer set 4 with a protruding condition. Specifically, one end of the convex conditioner is connected to the end of the rack assembly 3, and the other end passes through the back of the main housing 1, used to align the center point of the support 6 when the main housing 1 is placed. The pointer assembly 4 is slidably mounted on the surface of the main housing 1, and includes a first pointer 41 and a second pointer 42, used to align the two sides of the support 7. Specifically, the first pointer 41 and the second pointer 42 form a right-angled triangle, and when their right-angled sides are aligned with the two sides of the support 7, the values ​​on the corresponding scale lines 5 can be read simultaneously. The scale lines 5 are laser-engraved on the surface of the main housing 1, growing outwards from the center of the main housing 1 as the zero point, providing an intuitive reading method. In some embodiments, the scale unit of the scale lines 5 is millimeters or centimeters. It should be noted that the measuring device can be one or more types, and the scale unit of the scale lines 5 is not specifically limited.

[0027] Reference Figure 1 When the main housing 1 is stably placed on the support 6, the rack assembly 3 is pushed to move axially, causing the convex end of the rack assembly to contact and fit against both sides of the support 6. At this time, the zero point of the scale line 5 is aligned with the center point of the support 6. Then, the first pointer 41 and the second pointer 42 are simultaneously aligned with both sides of the sliding support 7. The scale value corresponding to the right angle side of the first pointer 41 and the second pointer 42 is read. The larger reading is subtracted from the smaller reading, and the difference between the two scale values ​​is divided by two to obtain the offset of the sliding pipe support, thus completing the measurement of the offset of the sliding pipe. Compared with traditional measurement methods, this measuring device reduces multiple manual measurements and improves work efficiency. At the same time, no complicated tools or steps are required. The measurement results can be obtained simply by placing the measuring device and adjusting the components. The measurement operation is simple, thereby reducing labor costs and reducing measurement errors. The accurate measurement results ensure that the sliding pipe support can be stably held on the support 6 after displacement according to the set expansion length when the steam pipe is heated, ensuring the safe operation of the heating pipeline.

[0028] In this embodiment, refer to Figure 1 The gear set 2 includes a middle gear 21, a left gear 22, and a right gear 23. The middle gear 21 is aligned with the zero point of the scale line 5, the left gear 22 is positioned to the left of the middle gear 21, and the right gear 23 is positioned to the right of the middle gear 21. Furthermore, the distance between the left gear 22 and the middle gear 21 is equal to the distance between the right gear 23 and the middle gear 21. By maintaining the left gear 22 and the right gear 23 equidistant from the middle gear 21, the power from the rack set 3 can be evenly distributed, ensuring synchronized movement on both sides. This also ensures that when the main housing 1 is placed on the support 6, the zero point of the scale line 5 is accurately aligned with the center point of the support 6, thereby improving the accuracy of the measurement results.

[0029] In this embodiment, refer to Figure 1 and Figure 3 The rack assembly 3 includes a first rack 31 and a second rack 32. The first rack 31 meshes with the upper sides of the middle gear 21 and the right gear 23, while the second rack 32 meshes with the lower sides of the middle gear 21 and the left gear 22, further ensuring that the movement of the two racks is synchronized. The equal length of the first rack 31 and the second rack 32 ensures consistent movement during motion, preventing one rack from moving before the other.

[0030] Furthermore, the main housing 1 is also provided with a track groove 11 for the axial movement of the first rack 31 and the second rack 32. The track groove 11 serves a positioning function, enabling the two racks to move within a predetermined path and reducing the possibility of deviation or tilting. Specifically, the side of the track groove 11 facing the first rack 31 and the second rack 32 is also coated with grease.

[0031] Reference Figures 2-3 In this embodiment, the convex condition includes: a first convex strip 311 with one end connected to the end of the first rack 31 and the other end being a free end, and a second convex strip 321 with one end connected to the end of the second rack 32 and the other end being a free end. The first convex strip 311 and the second convex strip 321 are respectively connected to the ends of the rack assembly 3 that abut against the two sides of the main housing 1. Specifically, the two convex strips are located on both sides of the main housing 1, so that the force when pushing the rack assembly 3 to move axially is directly transmitted to drive the two convex strips to move axially within the main housing 1. In some embodiments, the free ends of the first convex strip 311 and the second convex strip 321 can find suitable contact points on the supports 6 of different shapes or sizes, thereby setting them to better fit the shape of both sides of the supports 6, so that the measuring device can adapt to a variety of different construction environments and support 6 types, enhancing its versatility and flexibility.

[0032] Furthermore, the main housing 1 is also provided with a clearance hole 12 for axial movement of the protrusion, which ensures the smooth movement of the first protrusion 311 and the second protrusion 321.

[0033] In this embodiment, refer to Figure 4 The main housing 1 has a through groove 13 for sliding assembly of the pointer group 4. The groove 13 ensures that the first pointer 41 and the second pointer 42 can move smoothly during the measurement process, reducing measurement errors caused by shaking or offset.

[0034] In this embodiment, the inner side of the groove 13 is provided with an outwardly protruding protrusion 131, and the pointer assembly 4 is provided with a recessed portion 43 that mates with the protrusion 131. The insertion and connection of the protrusion 131 and the recessed portion 43 not only restricts the radial movement of the pointer assembly 4, but also ensures that the first pointer 41 and the second pointer 42 always maintain the correct direction and position during sliding, further improving the positioning accuracy of the measurement.

[0035] In this embodiment, the two ends of the groove 13 are also provided with blocking blocks (not shown) to prevent the pointer group 4 from sliding out, which effectively prevents the pointer group 4 from accidentally sliding out of the groove 13 during operation.

[0036] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
