DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] Reference Figure 1-11 , a device for measuring the inclination angle of an escalator or moving walkway truss in this embodiment includes an angle plate 100 for installation on a horizontal section chord of an escalator or moving walkway truss and a measuring plate 200 for installation on an inclined section chord of an escalator or moving walkway truss. The measuring plate 200 and the angle plate 100 are connected by a fixed shaft assembly 400. The measuring plate 200 and the angle plate 100 can rotate around the axis of the fixed shaft assembly 400. Angle scale lines are engraved on the angle plate 100. The measuring plate 200 includes an indicating section 210 and an installing section 220. An indicating needle 211 for reading the inclination angle of the inclined section chord of the escalator or moving walkway truss is provided at one end of the indicating section 210 away from the installing section 220.

[0032] The angle plate 100 includes a fan-shaped scale plate 110, a connection portion 120 for fixing to the inclined section chord of the escalator or moving walkway truss, and a pointed mouth portion 130. The pointed mouth portion 130 is provided with a first mounting hole 131, and the first mounting hole 131 is the center of the circle where the scale plate 110 is located. The angle plate 100 is provided with an arc groove 140, and the circle where the arc groove 140 is located and the circle where the scale plate 110 is located are concentric circles. An upper scale area 111 and a lower scale area 112 are provided on the scale plate 110. The upper scale area 111 is used to detect the angle between the inclined section chord 600 of the escalator or moving walkway truss and the upper horizontal section chord 700 of the escalator or moving walkway truss, and the lower scale area 112 is used to detect the angle between the inclined section chord 600 of the escalator or moving walkway truss and the lower horizontal section chord 800 of the escalator or moving walkway truss. Of course, regardless of the upper scale area 111 or the lower scale area 112, the angle scale lines engraved thereon are the values ​​of the inclination angles of commonly used escalators, and the values ​​of the angle scale lines on the angle plate 100 are not limited to Figure 2 The scale shown can be increased as required.

[0033] The measuring plate 200 is a bent plate, including an indicating section 210 and a mounting section 220. The angle between the indicating section 210 and the mounting section 220 is an obtuse angle. The angle between the indicating section 210 and the mounting section 220 is related to the 0° angle scale position of the matching angle plate 100. Specifically, when the angle between the mounting section of the measuring plate 200 and the connecting portion 120 of the angle plate 100 is 180°, that is, when the two are in a straight line, the indicating position of the indicating needle 211 of the indicating section 210 on the angle plate 100 is recorded as 0°, and the other commonly used angle scale values ​​are marked accordingly based on the marked 0°. A second mounting hole 230 is provided at the bending portion of the measuring plate 200, and a third mounting hole 240 is provided on the indicating section 210 of the measuring plate 200. The distance between the third mounting hole 240 and the second mounting hole 230 is equal to the distance between any point on the center line of the arc groove 140 and the first mounting hole 131. The third mounting hole 240 is penetrated by a locking bolt 300 and a butterfly nut 500. The locking bolt 300 includes a locking bolt head 310 and a locking bolt body 320. The locking bolt head 310 is located on a side close to the angle plate 100, and the butterfly nut 500 is located on a side close to the measuring plate 200. A display frame 212 is provided at one end of the indicating section 210 away from the mounting section 220. A side of the display frame 212 away from the mounting section 220 is recessed into the display frame 212 to form an indicating needle 211, and the needle head of the indicating needle 211 faces the mounting section 220.

[0034] In addition, the arc groove 140 on the angle plate 100 is used for the locking bolt body 320 to slide therein, thereby allowing the indicating section 210 of the measuring plate 200 to rotate.

[0035] Of course, a base 900 is provided on the mounting section 220 of the measuring plate 200 and the connecting portion 120 of the angle plate 100. Specifically, the base 900 is in a concave shape, and the base 900 has a recessed mouth 910 that is recessed inward. The mounting section 220 of the measuring plate 200 and the connecting portion 120 of the angle plate 100 are fixed in the recessed mouth 910 by welding. Of course, other fixing methods can also be adopted.

[0036] The fixed shaft assembly 400 includes a sleeve 410, a fastening bolt 420 and a gasket 430. The sleeve 410 includes a sleeve head and a sleeve body. The sleeve is provided with a threaded hole along the axial direction. The fastening bolt 420 includes a fastening bolt head and a fastening bolt body. The threaded hole is for the fastening bolt body to be screwed in. The sleeve body passes through the first mounting hole 131 and the second mounting hole 230. The sleeve head is located on the side close to the angle plate 100, and the fastening bolt head is located on the side close to the measuring plate 200. The gasket 430 is located between the fastening bolt 420 and the sleeve 410. The length of the sleeve body of the sleeve 410 is greater than the total thickness of the angle plate 100 and the measuring plate 200, thereby ensuring that there is a gap 440 between the measuring plate 200 and the gasket 430.

[0037] When using, refer to Figure 8 , Fig. 9 As shown, first, the base 900 on the angle plate 100 is fitted with the upper horizontal segment chord 700 of the escalator or moving walkway truss or the lower horizontal segment chord 800 of the escalator or moving walkway truss, and then the measuring plate 200 is rotated. If necessary, the angle plate 100 can be moved forward and backward to make the base 900 on the measuring plate 200 fit with the inclined segment chord 600 of the escalator or moving walkway truss, and then the butterfly nut 500 and the locking bolt 300 are tightened. The angle between the upper horizontal segment chord 700 of the escalator or moving walkway truss and the inclined segment chord 600 of the escalator or moving walkway truss and the angle between the lower horizontal segment chord 800 of the escalator or moving walkway truss and the inclined segment chord 600 of the escalator or moving walkway truss can be read through the display frame of the measuring plate 200.
