The detecting device 100 includes a main scale 110, a fixed arm 120, a moving arm 130, and a distance measuring part 140. The main scale 110 provides a mounting base for the fixed arm 120, the moving arm 130 and the distance measuring piece 140, the fixed arm 120, the moving arm 130 and the distance measuring piece 140 are mounted on the main scale 110, the fixed arm 120 provides a reference base for detection, the moving arm 130 slides relative to the fixed arm 120, and the distance measuring instrument 140 is used for detecting the sliding distance of the moving arm 130 to obtain the gap parameter.

The main scale 110 extends in a first direction, specifically, in the embodiment, the first direction is a horizontal direction of the main scale 110 when the main scale is horizontally arranged as shown in fig. 1, and the first direction is changed when the detection device 100 rotates. The fixing arm 120 extends along a second direction intersecting the first direction, specifically, an included angle between the second direction and the first direction is greater than 0 degree and less than 180 degrees, and in this embodiment, the second direction is a vertical direction perpendicular to the first direction. The fixed arm 120 has a reference surface 121, and the reference surface 121 needs to be attached to the first surface to be detected 210 during the detection process. In addition, the reference surface 121 extends in the second direction, and the reference surface 121 faces toward or away from the plane where the end surface of the main scale 110 is located. Specifically, taking fig. 1 as an example, the reference surface 121 is a right side surface or a left side surface of the fixing arm 120, and a plane where an end surface of the main scale 110 is located may be a plane where an end surface of the main scale 110 is located on a left side or a plane where an end surface of the main scale 110 is located on a right side.

The moving arm 130 extends in a first direction and has a detecting end. The movable arm 130 includes a return-to-zero state and a detection state, when the movable arm is in the return-to-zero state, an end tail of the detection end is aligned with the reference surface 121, when the movable arm is in the detection state, an end tail of the detection end is aligned with the second surface to be detected 220, and the movable arm 130 is operable to slide along the first direction and can be switched between the return-to-zero state and the detection state. Optionally, when the detection end is tapered, the end tail of the detection end is a point, in this case, the end tail of the detection end is aligned with the reference surface 121, which means that a point of the end tail of the detection end is located in the plane of the reference surface 121, and the end tail of the detection end is aligned with the second surface to be measured 220, which means that a point of the end tail of the detection end is located in the plane of the second surface to be measured 220; when the end face of the detection end is a plane, the plane is an end tail of the detection end, in this case, the end tail of the detection end is aligned with the reference plane 121, which means that the end face of the detection end and the reference plane 121 are located in the same plane, and the end tail of the detection end is aligned with the second surface to be detected 220, which means that the end face of the detection end and the second surface to be detected 220 are located in the same plane; when the detection end is spherical, the end tail of the detection end is a point, in this case, the alignment of the end tail of the detection end with the reference plane 121 indicates that the most protruded point of the end tail of the detection end is located in the plane of the reference plane 121, and the alignment of the end tail of the detection end with the second surface to be measured 220 indicates that the most protruded point of the end tail of the detection end is located in the plane of the second surface to be measured 220. It should be noted that, when the end tail of the detection end is a point, the end tail of the detection end is aligned with a certain surface, and can be achieved by abutting the end tail against the surface, or by arranging the end tail in parallel with the surface at intervals, or by arranging the end tail in parallel with the surface and abutting against the surface; when the end tail of the detection end is a plane, the end tail of the detection end is aligned with a certain surface, and the end tail can be realized by arranging the end face of the detection end opposite to the surface, attaching and coplanarity, or arranging the end face of the detection end in parallel to the surface, and attaching and coplanarity at most. The distance measuring unit 140 is used to measure the sliding distance of the moving arm 130 from the zeroing state to the detecting state, so as to obtain the gap parameter between the first surface under test 210 and the second surface under test 220.

Specifically, when detecting the gap parameter between the first surface to be detected 210 and the second surface to be detected 220, the moving arm 130 slides, the end tail of the detection end aligns with the reference surface 121, and the distance measuring unit 140 returns to zero; then, the reference surface 121 is attached to the first surface to be measured 210, and the moving arm 130 continues to slide, so that the end tail of the detection end is aligned with the second surface to be measured 220. Next, the distance measuring unit 140 detects a sliding distance of the moving arm 130 from the zeroing state to the detecting state, which is a gap parameter between the first surface to be measured 210 and the second surface to be measured 220. Further, since the reference surface 121 faces toward or away from the plane where the end surface of the main scale 110 is located, different surfaces of the fixing arm 120 can be selected as the reference surfaces 121 according to different first surfaces 210 to be measured, and then the distance measuring part 140 measures the distance by sliding the moving arm 130, so that the gap parameters under different conditions can be obtained. Therefore, the detection device 100 can be used singly to measure a plurality of clearance parameters of the elevator, so that the detection process of the detection device 100 is simpler and the detection efficiency is higher.

Alternatively, the main scale 110, the fixed arm 120 and the movable arm 130 may be in a shape of a long strip, a cylinder, a rectangular parallelepiped or other shapes, the fixed arm 120 and the movable arm 130 may be respectively distributed on two opposite sides of the main scale 110, or two adjacent sides, and so on, and the following embodiments are described by taking the main scale 110 as a rectangular parallelepiped and the fixed arm 120 and the movable arm 130 as examples of being respectively distributed on two opposite sides of the main scale 110.

The use of the detection device 100 will be described in detail with reference to fig. 2, taking as an example the detection device 100 for detecting the depth of engagement of the comb teeth 240 of the comb plate with the tread surface grooves 230.

In the escalator, the bottom surface of the comb plate teeth 240 engaged in the tread surface tooth grooves 230 is the first surface to be measured 210, and the tread surface is the second surface to be measured 220. During detection, the moving arm 130 slides until the end tail of the detection end is aligned with the reference surface 121, and the distance measuring piece 140 returns to zero; then, the moving arm 130 slides until the moving arm 130 is positioned above the tread surface; then, the fixed arm 120 extends deeply into the tread surface tooth slot 230, the reference surface 121 of the fixed arm 120 is attached to the bottom surface of the comb teeth 240 of the comb plate, and the first direction is kept to be the same as the perpendicular direction of the bottom surface of the tread surface tooth slot 230; next, the moving arm 130 slides in the first direction until the end of the detection end abuts against the tread surface 250. Further, the distance measuring unit 140 measures a distance from a position where the end-to-end of the detection end is aligned with the reference surface 121 to a position where the detection end abuts against the tread surface 250 of the escalator, which is a depth of engagement between the tread surface tooth grooves 230 and the comb teeth 240 of the escalator.

In one embodiment, the moving arm 130 includes a first end 131 and a second end 132 disposed opposite to the first end 131 and rollable relative to the first end 131, and the first end 131 or the second end 132 forms a detecting end.

Referring to fig. 3, in particular, when the first end 131 is used as the detecting end, the detecting apparatus 100 is used for measuring a single gap parameter between the first surface to be measured 210 and the second surface to be measured 220. Fig. 3 is a schematic diagram illustrating the detection device 100 detecting the engagement depth of the elevator door slider 260 in the vertical elevator according to an embodiment of the present invention. In the vertical elevator, the elevator door slider 260 is partially engaged with the elevator door sill groove 270, the first surface to be measured 210 is the bottom surface of the elevator door slider 260 engaged in the sill groove 270, and the second surface to be measured 220 is the top surface of the elevator door sill. During detection, the moving arm 130 slides, so that the end tail of the first end 131 is aligned with the reference surface 121, and the distance measuring piece 140 returns to zero; then, the fixing arm 120 extends into and is accommodated in the sill groove 270, the reference surface 121 of the fixing arm 120 faces the opening of the sill groove 270 and is attached to the bottom surface of the elevator door slider 260, and the first direction is the same as the perpendicular direction of the bottom surface of the sill groove 270; then, the moving arm 130 slides along the first direction until the first end 131 abuts against the top surface of the elevator door sill; next, the distance measuring device 140 detects a distance from the position where the first end 131 is aligned with the reference surface 121 to the position where the first end is abutted against the top surface of the elevator door sill, which is the engagement depth of the elevator door slider 260. If the clearance parameter meets the national standard, the elevator is manufactured to meet the standard, otherwise, the elevator is possibly derailed in the sliding process and needs to be stopped or used after being overhauled.

Referring to fig. 4, specifically, when the second end 132 is used as the detecting end, the detecting apparatus 100 is used for measuring a set of continuous gap parameters between the first surface to be measured 210 and the second surface to be measured 220. Fig. 4 shows a schematic diagram of an embodiment of the present invention in which the detecting device 100 detects a gap parameter between the elevator door 310 and the elevator door frame 290 in a vertical elevator. Specifically, in the present embodiment, the first surface to be measured 210 is a frame surface of the elevator door frame 290 facing the elevator door 310, and the second surface to be measured 220 is a door panel surface of the elevator door 310 facing the elevator door frame 290. During detection, the moving arm 130 slides until the end of the second end 132 is aligned with the reference surface 121, and the distance measuring piece 140 returns to zero; next, the detecting device 100 is placed outside the elevator car, the fixed arm 120 is hooked on the elevator door frame 290, the reference surface 121 is attached to the door frame surface, then the moving arm 130 slides, the end of the second end 132 abuts against the door leaf surface, then, the whole detecting device 100 is operated to slide along the gap extending direction between the elevator door leaf 310 and the elevator door frame 290, and it is ensured that the reference surface 121 is always attached to the door frame surface, the end of the second end 132 always abuts against the door leaf surface, and thus a set of continuous gap parameters between the door leaf surface and the door frame surface can be measured.

By providing the first end 131 and the second end 132, the operator can select different ends as the detection ends according to different detection requirements, so that the detection apparatus 100 has wider applicability. When a single gap parameter is measured, the sliding of the moving arm 130 can be finished and the sliding distance of the moving arm 130 can be measured by abutting the first end 131 with the second surface to be measured 220, so that the measuring process of the detection device 100 is simple and convenient, and the working efficiency is improved conveniently; when continuous gap parameters are measured, the second end 132 abuts against the second surface to be measured 220, and in the sliding process of the moving arm 130, the second end 132 can roll relative to the first end 131, so that the friction force between the second end 132 and the second surface to be measured 220 can be effectively reduced, the wear of the second end 132 is smaller, and the service life of the detection device 100 can be further prolonged.

Further, the outer diameter of the first end 131 gradually decreases along the direction from the second end 132 to the first end 131, the second end 132 is a spherical structure or a cylindrical structure, and the end surface of the second end 132 is an arc surface.

The outer diameter of the first end 131 is gradually reduced along the direction from the second end 132 to the first end 131, the smaller the area of the end tail of the first end 131 is, and the smaller the difficulty in manufacturing and forming the end face of the first end 131 into a smooth surface is, so that when the first end 131 abuts against the second surface to be measured 220, the better the fitting degree between the first end 131 and the second surface to be measured 220 is, thus, the measurement error is smaller, and the measurement accuracy is higher; the second end 132 is configured to be a spherical structure or a cylindrical structure, and the spherical structure or the cylindrical structure can roll relative to the first end 131 when rotating around the central axis of the spherical structure or the cylindrical structure, so that the second end 132 is simpler to form and simpler and more convenient to operate. Specifically, the end surface of the second end 132 is an arc surface, the arc surface is an outer surface of a spherical structure or a side wall of a cylindrical structure, and when the arc surface is aligned with the reference surface 121 and the second surface to be measured 220, the most protruded top line of the arc surface is aligned with the reference surface 121 and the second surface to be measured 220.

In one embodiment, the detecting device 100 further includes a locking member 150, the main scale 110 has a plurality of locking holes spaced along the first direction, the moving arm 130 has a plurality of mounting holes (not shown), and the locking member 150 is operatively disposed through the mounting holes and the locking holes aligned in position and cooperates with the mounting holes and the locking holes to fix the moving arm 130. When the moving arm 130 slides to the end tail of the detection end to align with the reference surface 121 or slide to abut against the second surface to be measured 220, the locking member 150 can be used to fix the moving arm 130, and the distance measuring member 140 measures the moving distance of the moving arm 130, so as to obtain the gap parameter. Through the arrangement of the locking member 150, the movable arm 130 can be prevented from sliding in the process of distance measurement reading of the distance measurement member 140, so that the distance measurement result is more accurate, and the detection precision of the detection device 100 can be effectively improved. After the detection is finished, the locking member 150 may be used to lock the moving arm 130, so as to facilitate the storage of the detection apparatus 100.

Alternatively, the locking member 150 may be a latch, bolt, or other structure, and in one embodiment, the locking member 150 is a bolt. The bolt is tightened, the movable arm 130 can be locked, the bolt is loosened, the movable arm 130 can be operated to slide and/or rotate relative to the main scale 110, the movable arm 130 slides to enable the end tail of the detection end to be aligned with the reference surface 121 or the second surface to be detected 220, and the movable arm 130 rotates to select and replace the detection end according to actual detection requirements.

Referring to fig. 5, fig. 5 shows a schematic diagram of an embodiment of the present invention, in which the detecting device 100 detects the depth of engagement between the comb teeth 240 and the tread tooth grooves 230 of the escalator, and in the detecting process, the moving arm 130 can be rotated, and the bottom end of the moving arm 130 extending along the length direction is defined to be used as a detecting end.

Specifically, taking the locking member 150 as a bolt as an example, the bolt is loosened, and the moving arm 130 slides relative to the main scale 110 in the extending direction of the slide 113. The slide 113 is provided to operate the moving arm 130 to slide without detaching the locking member 150, so that the detection efficiency can be further improved.

In some embodiments, the locking element 150 may also be a conical shaped latch. The locking member 150 has a large end and a small end, the small end is inserted through the aligned assembly hole and the locking hole, and the shape of the assembly hole and the locking hole matches with the shape of the locking member 150. When the moving arm 130 is operated to slide, the locking member 150 is partially pulled out of the locking hole or the slide 113.

In some embodiments, the detecting device 100 further includes a sliding member 180 received in the sliding channel 113 and slidable along the sliding channel 113, and the locking member 150 is disposed through the sliding member 180. Specifically, the shape of the sliding member 180 matches the sliding space of the sliding rail 113, and a limiting effect is provided between the inner wall of the sliding rail 113 and the sliding member 180, so that when the moving arm 130 and the sliding member 180 slide relatively, the limiting effect between the two can make the sliding of the moving arm 130 and the sliding member 180 more stable.

Referring to fig. 6, in an embodiment, the detecting device 100 further includes a sliding arm 160, the sliding arm 160 is mounted on the main scale 110 and has a sliding component 163 extending along the second direction, the sliding component 163 has a sliding surface 161 disposed parallel to the reference surface 121, and the sliding arm 160 is operable to slide along the first direction to adjust a distance between the sliding surface 161 and the reference surface 121.

Specifically, the distance between the sliding surface 161 and the reference surface 121 is a clearance parameter between the first surface to be measured 210 and the second surface to be measured 220. The fixed arm 120 and the sliding part 163 are used in cooperation, the outer diameter or the length of the piece to be measured can be measured, and the fixed arm 120, the sliding part 163 and the moving arm 130 are used in cooperation, and the gap parameter between the left door leaf 320 and the right door leaf 330 after the vertical elevator is closed can also be detected.

For example, if the outer diameter of the dut needs to be detected, the fixed arm 120 and the sliding arm 160 respectively have a first surface and a second surface that are disposed opposite to each other, the first surface is a reference surface 121, the second surface is a sliding surface 161, the sliding member 163 is operated to slide to a position where the dut is clamped between the reference surface 121 and the sliding surface 161, and then the distance measuring device 140 measures the distance between the reference surface 121 and the sliding surface 161, which is the outer diameter of the dut.

The following description will be made with reference to fig. 6, taking as an example a case where the detection device 100 detects a gap parameter between the left door 320 and the right door 330. If the gap parameter between the left door 320 and the right door 330 is detected after the vertical elevator is closed, the fixed arm 120 and the sliding arm 160 respectively have a third surface and a fourth surface that are separated from each other, the third surface is a reference surface 121, the fourth surface is a sliding surface 161, first, the fixed arm 120 and the sliding member 163 are clamped between the left door 320 and the right door 330, the reference surface 121 is in contact with the surface of the left door 320, the sliding surface 161 is in contact with the surface of the right door 330, then, the end-to-end of the detecting end of the moving arm 130 is aligned with the reference surface 121, the distance measuring piece 140 is zeroed, then, the moving arm 130 slides to align the end of the detecting end with the sliding surface 161, and then the distance measuring device 140 measures the distance from the position where the end of the detecting end slides from the position where the end of the detecting end is aligned with the reference surface 121 to the position where the end of the detecting end is aligned with the sliding surface 161, where the distance is the gap parameter between the left door 320 and the right door 330. It should be noted that, when detecting a gap parameter between the left door 320 and the right door 330 after the vertical elevator is closed, only the fixed arm 120 and the moving arm 130 may be used, a specific detection process is to operate the reference surface 121 to be attached to the surface of the left door 320, then the moving arm 130 moves to align the end tail of the detection end with the reference surface 121, the distance measuring unit 140 returns to zero, then the moving arm 130 slides to align the end tail of the detection end with the right door 330, then the distance measuring unit 140 measures the position where the end tail of the detection end is aligned with the reference surface 121 and the position where the end tail of the detection end is aligned with the surface of the left door 320, and a distance between two positions measured by the distance measuring unit 140 is the gap parameter between the left door 320 and the right door 330. However, during the whole measurement process, due to the lack of support of the right door leaf 330, the stability of the detection device 100, the measured gap parameter error is large.

In one embodiment, the detecting device 100 further includes a detaching member 170, and the sliding arm 160 is detachably mounted to the main scale 110 through the detaching member 170. By providing the detaching member 170, the detecting person can detach or replace the sliding arm 160 according to the specific detection requirement, so that the detecting device 100 has wider applicability. For example, if the gap parameter between the left door 320 and the right door 330 of the vertical elevator needs to be detected, the sliding arm 160 is installed, and if the gap parameter between the elevator door 310 and the elevator door frame 290 of the vertical elevator needs to be detected, the sliding arm 160 is removed to prevent the sliding arm 160 from abutting against the elevator door frame 290 and the detection is not performed.

In one embodiment, the dismounting member 170 includes a first dismounting member 171 and a second dismounting member 172, the sliding arm 160 further includes a sliding body 162, the sliding body 162 is slidably mounted to the main ruler 110 and is connected to the main ruler 110 through the first dismounting member 171, and the sliding member 163 is connected to the sliding body 162 through the second dismounting member 172. By providing the first and

second detachers

171 and 172, the sliding body 162 and/or the sliding member 163 may be detached according to the inspection requirement, so as to improve the efficiency of the handling. For example, when it is necessary to detach the entire slide arm 160, the first detachment member 171 may be detached, and when it is necessary to detach only the slide member 163, only the second detachment member 172 may be detached.

Alternatively, the distance measuring unit 140 may be a scale disposed on the main scale 110, when the moving arm 130 is in the zeroing state, the main scale 110 has a first scale aligned with the end and the tail of the detecting end, when the moving arm 130 is in the detecting state, the main scale 110 has a second scale aligned with the end and the tail of the detecting end, and an absolute value of a difference between the first scale and the second scale is the gap parameter.
