For example, in the claims, any one of the claimed embodiments can be used in any combination.
[0021] The following refers to the drawings Figure 1 to the drawings Figure 5 A conduit frame angle measurement tool and a measurement method are described.
[0022] The present embodiment provides a conduit frame angle measurement tool,Figure 1 The structural schematic diagram of the pipe rack angle measuring tool in working is shown in FIG. 1. Figure 1 As shown in FIG. 1, the pipe rack angle measuring tool is installed between two pipe racks 4 arranged at an angle, and is used for measuring the angle between the two pipe racks 4. The pipe rack angle measuring tool comprises a plurality of length-adjustable measuring units 1. The plurality of measuring units 1 are arranged at intervals, and the same end of the plurality of measuring units 1 is flush arranged and abuts against one of the pipe racks 4, and the other end abuts against the other pipe rack 4. The angle between the two pipe racks 4 is measured by the relative distance of the plurality of measuring units 1.
[0023] By arranging the plurality of length-adjustable measuring units 1, different positions of the two pipe racks 4 can be contacted at the same time, and the single-point measurement error can be reduced by comprehensive measurement data, so as to improve the accuracy of the angle measurement. The length-adjustable measuring unit 1 can adapt to pipe racks 4 with different distances, and has strong versatility. The plurality of measuring units 1 are arranged at intervals and the same end is flush arranged, so that the force is uniform during measurement, and the measurement deviation caused by tool inclination is avoided.
[0024] Further, Figure 2 The structural schematic diagram of the pipe rack angle measuring tool is shown in FIG. 1. Figure 3 The structural schematic diagram of the measuring unit is shown in FIG. 2. Figure 2 And Figure 3 As shown in FIG. 2, the measuring unit 1 comprises a first support 11 and a first adjusting part 12. The first adjusting part 12 can slide relative to the first support 11 to adjust the length of the measuring unit 1. By the sliding cooperation of the first support 11 and the first adjusting part 12, the stepless adjustment of the length of the measuring unit 1 is realized, and the accurate matching of different pipe rack 4 distances is met. The sliding adjustment mode is simple and intuitive, and is convenient for quick adjustment on site.
[0025] Further, the first support 11 is provided with two first supports 11, and the first adjusting part 12 is arranged between the two first supports 11. The two first supports 11 abut against the two pipe racks 4 respectively. The two first supports 11 abut against the two pipe racks 4 respectively to form symmetrical support and enhance the measurement stability. The first adjusting part 12 is located between the two supports to optimize the force transmission path and avoid the generation of partial load during adjustment.
[0026] Further, the first adjusting part 12 comprises a first guide sleeve 121 and a first fastener 122 arranged on the first guide sleeve 121, the first guide sleeve 121 is sleeved between the two first supports 11 and can slide relative to the two first supports 11, and the first fastener 122 abuts against the first support 11 to relatively fix the first support 11 and the first guide sleeve 121. The combination of the first guide sleeve 121 and the first fastener 122 can not only realize sliding adjustment, but also can be quickly locked by the fastener to ensure that the length is fixed and not loose during measurement. The guide sleeve is sleeved on the support to avoid the support from being separated during adjustment and improve safety. Further, the guide tube support angle measuring tool further comprises an adjusting unit 2 arranged between the measuring units 1, which is used to adjust the distance between the measuring units 1. The adjusting unit 2 can change the distance between adjacent measuring units 1 to adapt to guide tube supports 4 of different diameters or complex space layouts. Through the cooperative action of the adjusting unit 2 and the measuring unit 1, the tool can cope with more diversified measurement scenes.
[0027] Further, Figure 4 The structure diagram of the adjusting unit of the embodiment is shown in Figure 1 、 Figure 2 and Figure 4 The adjusting unit 2 comprises two second supports 21, the second supports 21 are respectively connected to adjacent first supports 11, and the adjusting unit 2 further comprises a second adjusting part 22, the first adjusting part 12 is arranged between the two first supports 11 and is used to adjust the relative distance between the two second supports 21. The second supports 21 are connected to adjacent first supports 11, the second adjusting part 22 synchronously controls the spacing of the plurality of measuring units 1 to realize efficient and unified adjustment. The adjusting unit 2 is designed separately from the measuring unit 1, which is convenient for maintenance or replacement of parts.
[0028] Further, the second adjusting part 22 comprises a second guide sleeve 221 and a second fastener 222 arranged on the second guide sleeve 221, the second guide sleeve 221 is sleeved between the two second supports 21 and can slide relative to the two second supports 21, and the first fastener 122 abuts against the second support 21 to relatively fix the second support 21 and the second guide sleeve 221.

The support units 3 directly abut against the pipe rack 4, so that damage caused by hard contact between the measuring tool and the pipe rack 4 is avoided. The support units 3 fix the position of the measuring tool, so that measurement deviation caused by human operation is reduced.
[0030] Further, the support units 3 are arranged in a semicircular shape, and the pipe rack 4 can be accommodated in the inner wall of the semicircular support unit 3, so that the inner wall of the support unit 3 abuts against the pipe rack 4. The semicircular support unit 3 is perfectly fitted with the cylindrical pipe rack 4, so that the contact area is increased and the stability is enhanced. The semicircular structure limits the radial movement of the pipe rack 4, so that the tool does not slide or rotate during the measurement process.
