[0033] It should also be noted that the directional terms mentioned in the embodiments, such as "up", "down", "front", "back", "left", "right", etc., are only reference directions of the drawings, and are not intended to limit the protection scope of the utility model. Throughout the drawings, the same elements are represented by the same or similar reference numerals. When it may cause confusion to the understanding of the utility model, the conventional structure or configuration will be omitted.

[0034] In the escalator modification process, the trajectory surface of the bent edge of the escalator step is not easy to simulate and measure. The working point formed by the intersection position of the trajectory surface of the bent edge of the escalator step and the plane of the ground at the end of the escalator is not easy to measure, resulting in large measurement error and low measurement efficiency.

[0035] The first aspect of the utility model provides an escalator working point measuring device, referring to Figure 1 and Figure 2 The escalator working point measuring device includes a measuring scale 2 and at least one supporting mechanism 4. The side surface of the measuring scale 2 is arranged to be in contact with the bent edge 12 of each step 11 of the escalator 1, so as to measure the horizontal distance between the working point 5 intersected by the plane where the upper ground 7 and / or the lower ground 7 at the end of the escalator 1 and the supporting angle steel 13 of the escalator 1. The at least one supporting mechanism 4 is movably connected to the side of the measuring scale 2 facing the step 11, and is configured to be supported on the top surface of the step 11 to prevent the measuring scale 2 from moving relative to the step 11.

[0036] In detail, the side surface of the measuring scale 2 is in contact with the bent edge 12 of each step 11 of the escalator 1, so that the placement direction of the measuring scale 2 is the same as the running direction of the step 11 of the escalator 1, and the measuring scale 2 can simulate the trajectory surface of the bent edge 12 of each step 11 of the escalator 1.

[0037] It should be noted that the escalator 1 is arranged between two floors of a building, the bottom end of the escalator 1 is arranged at the lower floor through the support angle steel 13, and the top end of the escalator 1 is arranged at the upper floor through the support angle steel 13. The lower ground surface 7 represents the ground surface 7 of the lower floor. The upper ground surface 7 represents the ground surface 7 of the upper floor.

[0038] It should be noted that, referring to Figure 1 , during the measurement of the bottom end of the escalator 1, the excess steps 11 of the trajectory surface formed by the bent edge 12 of the steps 11 at the middle of the escalator 1 at the bottom end of the escalator 1 need to be removed, so that when the measuring ruler 2 is placed at the bottom end of the escalator 1, the bottom end of the measuring ruler 2 is below the plane where the lower ground surface 7 is located, so as to intersect the plane where the lower ground surface 7 is located to form the working point 5, and measure the horizontal distance between the working point 5 and the support angle steel 13 located at the lower ground surface 7.

[0039] Referring to Figure 2 , during the measurement of the top end of the escalator 1, the excess steps 11 of the trajectory surface formed by the bent edge 12 of the steps 11 at the middle of the escalator 1 at the top end of the escalator 1 need to be removed to avoid obstruction, so that when the measuring ruler 2 is placed at the top end of the escalator 1, the top end of the measuring ruler 2 is above the plane where the upper ground surface 7 is located, so as to intersect the plane where the lower ground surface 7 is located to form the working point 5, and measure the horizontal distance between the working point 5 and the support angle steel 13 located at the upper ground surface 7.

[0040] Further, referring to Figure 1 and Figure 2 , during the measurement of the working point 5, the cover of the foundation pit 71 at the end of the escalator 1 can be removed, and the laser instrument 6 is placed in the foundation pit 71, so that the laser generated by the laser instrument 6 is coplanar with the upper ground surface 7 or the lower ground surface 7. In this way, the laser generated by the laser instrument 6 projects on the measuring ruler 2 to form the working point 5, that is, the working point 5 formed by the intersection of the plane where the upper ground surface 7 and / or the lower ground surface 7 is located and the measuring ruler 2.

[0041] Further, referring to Figure 1 and Figure 2 , the length of the measuring ruler 2 is less than the length of the escalator 1 in the running direction. The measuring ruler 2 can be located at the top end or the bottom end of the escalator 1 for measurement. In this way, the measuring ruler 2 is convenient to carry, and the convenience of use is improved.

[0042] Referring to Figure 1 , Figure 2 and Figure 3As shown, the support mechanism 4 is movably connected to the side of the measuring ruler 2 facing the step 11. The support mechanism 4 includes, but is not limited to, being installed on the side of the measuring ruler 2 facing the step 11 through a hinge, a buckle assembly, a magnetic assembly, or any other movable connection manner. The support mechanism 4 is supported on the top surface of the step 11, which can prevent the measuring ruler 2 from moving relative to the step 11, or adjust the support mechanism 4 so that the support mechanism 4 is attached to the top surface of the step 11, thereby improving the stability of the measuring ruler 2 and the support mechanism 4. In this way, the hands of the staff can be freed from positioning the measuring ruler 2 by manpower or positioning devices, thereby improving the convenience and measurement efficiency.

[0043] It should be noted that in the case that the horizontal distance measurement value between the working point 5 and the support angle steel 13 at the end of the corresponding escalator 1 is smaller, the newly installed step 11 of the escalator 1 will move outward relative to the step 11 of the original escalator 1, which will cause the size of the step 11 and the surrounding building of the escalator 1 to decrease, which does not meet the requirements. Conversely, the newly installed step 11 of the escalator 1 will move inward relative to the step 11 of the original escalator 1, which will cause the size of the step 11 and the surrounding building of the escalator 1 to increase, which also does not meet the requirements.

[0044] According to the embodiments of the present application, when the escalator 1 is transformed or repaired, the side of the measuring ruler 2 is in contact with the bent edge 12 of each step 11 of the escalator 1, and the support mechanism 4 is supported on the top surface of the step 11, thereby positioning the measuring ruler 2 and preventing the measuring ruler 2 from moving relative to the step 11, thereby improving the convenience and measurement efficiency. At this time, the measuring ruler 2 can simulate the trajectory surface of the bent edge 12 of each step 11 of the escalator 1, the plane on which the upper ground 7 at the top end of the escalator 1 and / or the lower ground 7 at the bottom end of the escalator 1 is located intersects with the measuring ruler 2 to form the working point 5, thereby facilitating the measurement of the horizontal distance between the working point 5 and the support angle steel 13 at the end of the corresponding escalator 1, and improving the measurement efficiency and accuracy.

[0045] In an exemplary embodiment, referring to Figure 2 , Figure 3 and Figure 4 As shown, the measuring ruler 2 includes a plurality of measuring ruler units 21 which are connected end to end in a first direction and are detachably connected through the connecting mechanism 3.

[0046] In detail, when the measuring ruler 2 is placed on the escalator 1 and in contact with the bent edge 12 of each step 11 of the escalator 1, the first direction is parallel to the running direction of the escalator 1. The connecting mechanism 3 includes, but is not limited to, a bolt 4111, a connecting block and bolt 4111 assembly, a buckle assembly, etc., which are specifically defined according to actual needs.

[0047] It should be noted that the measuring ruler unit 21 is connected end to end to form the measuring ruler 2. The side of the measuring ruler 2 that contacts the step 11 of the escalator 1 is set to be coplanar, so as to avoid the unevenness of the measuring ruler unit 21 due to the connection through the connecting mechanism 3, thereby reducing the error caused by the contact between the measuring ruler 2 and the bent edge 12 of the step 11 of the escalator 1, and further improving the measurement accuracy.

[0048] In this implementation, multiple measuring ruler units 21 are detachable, which facilitates the disassembly and installation of the measuring ruler 2, thereby making it easier to store the measuring ruler 2 and improving its portability.

[0049] In one exemplary embodiment, reference is made to Figure 4 , Figure 5 and Figure 6 As shown, the connecting mechanism 3 includes a connecting part 31 and a locking member 32. The two ends of the connecting part 31 are respectively inserted into the grooves 22 of the first measuring scale unit 211 and the second measuring scale unit 212 of the adjacent measuring scale units 21. The locking member 32 is disposed between the connecting part 31 and the measuring scale unit 21 to prevent the connecting part 31 from moving relative to the measuring scale unit 21.

[0050] In detail, the measuring ruler unit 21 is recessed inward to form a groove 22 extending in the first direction. The length of the groove 22 can be equal to the length of the measuring ruler unit 21. The length of the groove 22 can also be less than the length of the measuring ruler unit 21. The groove 22 is located at both ends of the measuring ruler unit 21. The connecting mechanism 3 is located inside the groove 22, so that the connecting mechanism 3 does not protrude from the outer surface of the measuring ruler unit 21, thereby ensuring that the side of the measuring ruler 2 that contacts the bent edge 12 of each step 11 of the escalator 1 is on the same plane, ensuring the accuracy of the measuring ruler 2 in simulating the trajectory surface of each step 11 of the escalator 1, and ensuring measurement accuracy.

[0051] Reference Figure 5 and Figure 6 As shown, each measuring scale unit 21 has four grooves 22, meaning that each measuring scale unit 21 has one groove 22 on its side, and the groove 22 penetrates through the side wall of the measuring scale unit 21. The number of grooves 22 can also be one, two, three, etc., depending on the measuring scale unit 21.

[0052] In detail, the number of locking mechanisms is the same as the number of grooves 22, with one locking mechanism provided in each groove 22. The two ends of the connecting part 31 of the locking mechanism are respectively inserted into the first measuring scale unit 211 of the adjacent measuring scale unit 21. Figure 4 The groove 22 of the measuring scale unit 21 located on the left and the second measuring scale unit 212 ( Figure 4The locking member 32 can be a screw or bolt 4111, which prevents the connecting part 31 from moving relative to the ruler unit 21.

[0053] In such an embodiment, the connecting part 31 is located in the groove 22 of the adjacent ruler unit 21 to connect the adjacent ruler units 21. The locking member 32 prevents the connecting part 31 from moving relative to the ruler unit 21, so that the adjacent ruler units 21 are connected end to end, and the ruler units 21 are easy to disassemble and assemble, thereby improving the convenience of disassembly and assembly and the measurement efficiency.

[0054] In an exemplary embodiment, as shown in Figure 4 , Figure 5 and Figure 6 , the groove 22 includes a first slot 221 and a second slot 222. The first slot 221 is formed in the interior of the ruler unit 21. The second slot 222 is in communication with the first slot 221 and penetrates the side wall of the ruler unit 21, and the caliber of the second slot 222 is smaller than that of the first slot 221. The connecting part 31 cooperates with the groove 22, the locking member 32 is threadedly connected with the connecting part 31, and the end of the locking member 32 away from the second slot 222 abuts against the ruler unit 21.

[0055] In detail, since the caliber of the second slot 222 of the groove 22 is smaller than that of the first slot 221, and the second slot 222 is in communication with the first slot 221 and penetrates the side wall of the ruler unit 21. Therefore, the cross section of the groove 22 from outside to inside is roughly a T-shaped slot, as shown in Figure 5 , the groove 22 at the top is roughly a T-shaped slot from top to bottom.

[0056] In such an embodiment, when the adjacent ruler units 21 are installed, the first end of the connecting part 31 is inserted into the groove 22 from the end of the first ruler unit 211. Then, the groove 22 of the second ruler unit 212 is aligned with the first ruler unit 211, so that the second end of the connecting part 31 is inserted into the groove 22 of the second ruler unit 212. Subsequently, the locking member 32 penetrates the connecting part 31 and is threadedly connected with the connecting part 31, and the end of the locking member 32 away from the second slot 222 abuts against the ruler unit 21. In this way, the locking member 32 has an outward abutting force on the connecting part 31, so that the connecting part 31 abuts against the side wall of the second slot 222 facing the first slot 221, thereby preventing the connecting part 31 from moving relative to the first ruler unit 211 and the second ruler unit 212, and further completing the installation of the adjacent ruler units 21, which are easy to disassemble and assemble, thereby improving the measurement efficiency of the work point 5 and the horizontal distance between the work point 5 and the support angle steel 13 at the end of the corresponding escalator 1.

[0057] In an exemplary embodiment, as shown in Figure 1, Figure 2 and Figure 3 As shown, the support mechanism 4 is movably connected to the measuring ruler unit 21 at the first end of the measuring ruler 2 on the side facing the step 11. Specifically, when measuring the working point 5 at the top of the escalator 1, the second end of the measuring ruler 2 extends to the top of the escalator 1, and when measuring the working point 5 at the bottom of the escalator 1, the second end of the measuring ruler 2 extends to the bottom of the escalator 1.

[0058] In detail, refer to Figure 3 As shown, the support mechanism 4 is movably connected to the first end of the measuring ruler 2. Figure 3 (The bottom of the measuring ruler 2). Since the measuring ruler 2 is formed by connecting multiple measuring ruler units 21 end to end, the support mechanism 4 can be set at one end of the measuring ruler 2. The specific position of the support mechanism 4 is determined according to actual needs.

[0059] Specifically, in Figure 1 In the process of measuring working point 5 at the bottom of escalator 1, the support mechanism 4 is supported on the top surface of step 11, the first end of measuring ruler 2 is located above, the second end of measuring ruler 2 is located below, extending to the bottom of escalator 1 and located below the lower ground 7, so as to intersect with the plane where the lower ground 7 is located to obtain working point 5.

[0060] exist Figure 2 In the process of measuring working point 5 at the top of escalator 1, support mechanism 4 is supported on the top surface of step 11, the first end of measuring ruler 2 is located below, the second end of measuring ruler 2 is located above, extending to the top of escalator 1 and located below the upper ground 7, so as to intersect with the plane where the upper ground 7 is located to obtain working point 5.

[0061] In one exemplary embodiment, reference is made to Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the support mechanism 4 includes a mounting mechanism 41 and a support assembly 42. The mounting mechanism 41 is positioned around a second direction perpendicular to the first direction (…). Figure 6 The vertical axis of the measuring scale unit 21 is rotatably disposed on the side facing the step 11. The support assembly 42 is disposed on the mounting mechanism 41 so that when measuring the working point 5 at the top or bottom of the escalator 1, the support assembly 42 abuts against the top surface of the step 11.

[0062] Specifically, in Figure 1 When measuring the working point 5 at the bottom of the escalator 1, the support mechanism 4 is in contact with the top surface of the step 11, and the first end of the measuring ruler 2 is located above. At this time, the support mechanism 4 and the first end of the measuring ruler 2 have an acute angle.

[0063] exist Figure 2In the embodiment, when the working point 5 at the top end of the escalator 1 is measured, the measuring scale 2 is turned 180°, the first end of the measuring scale 2 is located at the lower side, at this time, the support mechanism 4 is provided with an acute angle with the second end of the measuring scale 2, so that the support mechanism 4 of the first end of the measuring scale 2 is attached to the top surface of the step 11.

[0064] According to the embodiment of the utility model, in the process that the working point 5 at the bottom end of the escalator 1 is adjusted to the working point 5 at the top end of the escalator 1, the support assembly 42 is rotated around the axis of the second direction with the mounting mechanism 41, so that the support assembly 42 can be attached to the top surface of the step 11 in the case of measuring the working point 5 at the top or bottom of the escalator 1, to improve the stability of the positioning of the measuring scale 2.

[0065] In an exemplary embodiment, as shown in Figure 6 , Figure 7 and Figure 8 , the mounting mechanism 41 comprises a mounting assembly 411 and a mounting plate 412. The mounting assembly 411 is arranged on the measuring scale unit 21 and extends in the second direction. The mounting plate 412 is rotatably arranged on the mounting assembly 411, and the support assembly 42 is arranged on the mounting plate 412.

[0066] In detail, the mounting assembly 411 comprises but is not limited to a pivot, a pivot and bearing combination, a gear set or any other rotatable connecting assembly and the mounting plate 412 is rotatably connected, so that the mounting plate 412 is rotatably arranged on the measuring scale unit 21 around the axis of the second direction.

[0067] In such an embodiment, the mounting plate 412 is rotated around the axis of the second direction relative to the measuring scale unit 21 through the mounting assembly 411, so that the support assembly 42 is rotated around the axis of the second direction with the mounting plate 412, and the support assembly 42 can be attached to the top surface of the step 11 in the case of measuring the working point 5 at the top or bottom of the escalator 1.

[0068] In an exemplary embodiment, as shown in Figure 6 and Figure 8 , the mounting assembly 411 comprises a bolt 4111 and a matching part 4112. The bolt 4111 partially penetrates the measuring scale unit 21. The matching part 4112 is threadedly matched with the first end of the bolt 4111, preventing the bolt 4111 from being separated from the measuring scale unit 21. Wherein, the mounting plate 412 is rotatably sleeved on the bolt 4111.

[0069] In detail, the matching part 4112 is located in the groove 22 of the measuring scale unit 21. The bolt 4111 extends in the second direction, the bolt 4111 partially penetrates the measuring scale unit 21, and the first end of the bolt 4111 is threadedly matched with the matching part 4112. Figure 6The top of the bolt 4111 is threaded into the mating part 4112. In this way, the mating part 4112 prevents the bolt 4111 from disengaging from the measuring scale unit 21. The mounting plate 412 is provided with a through hole that allows the bolt 4111 to pass through, and the mounting plate 412 is rotatably fitted onto the bolt 4111.

[0070] According to an embodiment of this utility model, during the installation process, the bolt 4111 passes through the through hole of the mounting plate 412, and then the bolt 4111 engages with the mating part 4112 via a thread. This threaded engagement prevents the bolt 4111 and the mounting plate 412 from disengaging from the measuring scale unit 21, allowing the mounting plate 412 to rotate relative to the measuring scale unit 21 around the bolt 4111, thereby adjusting the position of the mounting plate 412 and the support assembly 42, so that the support assembly 42 abuts against the top surface of the step 11.

[0071] In one exemplary embodiment, reference is made to Figure 6 As shown, the measuring scale unit 21 is provided with a limiting groove 23, so that the mating part 4112 is partially inserted into the limiting groove 23 to prevent the mating part 4112 from rotating relative to the measuring scale unit 21.

[0072] In detail, the limiting groove 23 mates with the mating part 4112, and the limiting groove 23 is non-circular. In this way, the limiting groove 23 prevents the mating part 4112 from rotating relative to the measuring scale unit 21.

[0073] In this embodiment, during the process of the bolt 4111 rotating to tighten with the mating part 4112, the limiting groove 23 limits the mating part 4112, preventing the mating part 4112 from rotating relative to the measuring scale unit 21, thereby facilitating the tightening of the bolt 4111 and the mating part 4112, and further improving the ease of installation.

[0074] In one exemplary embodiment, reference is made to Figure 6 As shown, the mounting assembly 411 also includes a spacer ring 4113, which is sleeved on the second end of the bolt 4111 and abuts against the bolt 4111 and the measuring scale unit 21. The thickness of the spacer ring 4113 in the second direction is greater than the thickness of the mounting plate 412 in the second direction, so that the mounting plate 412 is rotatably sleeved on the spacer ring 4113.

[0075] In detail, the spacer ring 4113 is annular and is fitted onto the second end of the bolt 4111, that is, the spacer ring 4113 is located between the bolt 4111 and the mounting plate 412. The bolt 4111 presses the spacer ring 4113 against the measuring scale unit 21 between the measuring scale unit 21 and the second end of the bolt 4111. The spacer ring 4113 is located in the second direction ( Figure 6The thickness of the mounting plate 412 in the second direction is greater than the thickness of the mounting plate 412 in the vertical direction. In this way, there is a gap between the mounting plate 412 and the bolt 4111 head of the second end of the bolt 4111 and the measuring scale unit 21, facilitating the adjustment of the position of the mounting plate 412 around the bolt 4111. At the same time, the spacer ring 4113 reduces the friction between the mounting plate 412 and the bolt 4111, thereby reducing the degree of wear of the mounting plate 412 and the bolt 4111.

[0076] In an exemplary embodiment, referring to Figure 7 and Figure 8 The support assembly 42 includes a rotating assembly 421 and a support portion 422. The rotating assembly 421 is rotatably arranged on the mounting plate 412 about an axis parallel to the top surface of the step 11. The support portion 422 is arranged on the rotating assembly 421 such that the support portion 422 is parallel to and abuts against the top surface of the step 11.

[0077] In detail, the rotating assembly 421 can be a hinge. The rotating assembly 421 is arranged between the mounting plate 412 and the support portion 422, such that the support portion 422 rotates relative to the mounting plate 412 about an axis parallel to the top surface of the step 11. In this way, the angle between the support portion 422 and the mounting plate 412 and the measuring scale unit 21 can be adjusted, such that the support portion 422 is in close contact with the top surface of the step 11, thereby improving the stability of the positioning of the measuring scale 2 relative to the step 11 of the escalator 1, reducing the error of the horizontal distance between the work point 5 and the support angle steel 13 of the end of the corresponding escalator 1, and improving the measurement accuracy.

[0078] The second aspect of the utility model provides a kind of escalator work point measurement system, referring to Figure 1 and Figure 2 The escalator work point measurement system includes the escalator work point measurement device and laser instrument 6 as described above. The laser instrument 6 is located in the foundation pit 71 of the upper ground 7 or the lower ground 7 of the end of the escalator 1, and the laser instrument 6 is configured to generate laser, so that the laser is coplanar with the upper ground 7 or the lower ground 7 and is projected on the work point 5, to measure the horizontal distance between the work point 5 and the support angle steel 13 of the escalator 1. As described above, details are not repeated here.

[0079] According to the escalator 1 working point 5 measuring device and system provided by the embodiment, when the escalator 1 is transformed or maintained, the side surface of the measuring ruler 2 is contacted with the bending edge 12 of each step 11 of the escalator 1, and the supporting mechanism 4 is supported on the top surface of the step 11, so that the measuring ruler 2 is positioned and the movement of the measuring ruler 2 relative to the step 11 is prevented, the convenience and the measuring efficiency are improved. At this time, the measuring ruler 2 can simulate the trajectory surface of the bending edge 12 of each step 11 of the escalator 1, the plane where the upper ground 7 at the top end of the escalator 1 and / or the lower ground 7 at the bottom end of the escalator 1 is located intersects with the measuring ruler 2 to form the working point 5, so that the horizontal distance between the working point 5 and the corresponding support angle steel 13 at the end of the escalator 1 is measured conveniently, and the measuring efficiency and the measuring accuracy are improved.
