[0047] Refer to the attached Figure 1 The embodiment of the present application provides an elevator guide rail alignment detection device, including a base 1, a transverse movement mechanism 2, an elastic top-contact mechanism 3 and a marking assembly 4. The base 1 is used to be installed on a detection base 5, the elevator guide rail 6 to be tested is fixed on the base 1, and the transverse movement mechanism 2 is fixedly arranged on the base 1 and extends in the same direction as the base 1. The elastic top-contact mechanism 3 is fixed to the transverse movement mechanism 2, and one end of the elastic top-contact mechanism 3 away from the transverse movement mechanism 2 is in contact with the detection surface 601 of the elevator guide rail 6 to be tested. The elastic top-contact mechanism 3 is driven by the transverse movement mechanism 2 to move along the elevator guide rail 6 to be tested, and the elastic top-contact mechanism 3 can jump as the alignment of the detection surface 601 of the elevator guide rail 6 to be tested changes; the marking assembly 4 is fixed to the elastic top-contact mechanism 3, and moves with the elastic top-contact mechanism 3 and draws lines.

[0048] It can be imagined that by fixing the elevator guide rail 6 to be tested on the base 1, the transverse movement mechanism 2 configured on the base 1 is used to drive the elastic top contact mechanism 3 and the marking component 4 fixedly connected to the elastic top contact mechanism 3 to move along the detection surface 601 of the elevator guide rail 6 to be tested. If the straightness of the elevator guide rail 6 to be tested is abnormal, the elastic top contact mechanism 3 will jump during the movement along the elevator guide rail 6 to be tested, thereby making the line drawn by the marking component 4 a broken line shape, thereby not only being able to realize the detection of the elevator straightness during the movement, but also being able to mark the defect position, which is convenient for calibration and alignment.

[0049] Specifically:

[0050] like Figure 1As shown, the base 1 includes a rectangular crossbeam base plate, which has two wider panels, which are defined as a first panel and a second panel. The first panel has first connecting parts 101 formed integrally at both ends, and the first connecting parts 101 are used to be fixed to the detection base 5. The detection base 5 can be a detection table or any wall surface that can fix the crossbeam base plate. The second panel has second connecting parts 102 formed integrally at both ends, and the second connecting parts 102 are used to fix the elevator guide rail 6 to be tested.

[0051] like Figure 7 As shown, the elevator guide rail is provided with a mounting hole for fixed installation. Therefore, in the above, the second connecting part 102 includes a group of L-shaped connecting legs, each group of connecting legs is provided with a connecting hole corresponding to the mounting hole. Figure 6 As shown, the elevator guide rail is fitted between the two second connection parts 102, and the elevator guide rail can be fixed on the base 1 by passing bolts through the connection holes and the mounting holes and tightening with nuts.

[0052] Furthermore, the first connection part 101 is a T-shaped connection leg, and a through hole is provided on the transverse plate of the T-shaped connection leg. The base 1 can be installed on the detection base 5 by passing bolts or expansion screws through the through hole.

[0053] In this embodiment, the transverse movement mechanism 2 is a linear guide rail fixedly arranged on the base 1, and the guide rail section 201 of the linear guide rail is fixedly installed on one side of the second panel of the base 1, in the same direction as the second connecting portion 102, and a slider 202 is installed on the guide rail section 201. In a natural state, the slider 202 of the linear guide rail is located at one end of the base 1, and moves from one end of the base 1 to the other end of the base 1 during detection. As a conventional prior art, linear guide rails have the advantages of high precision, low friction, and long life, and can realize precise reciprocating linear motion. Of course, the transverse movement mechanism 2 is not limited to the use of linear guide rails, and mechanisms such as reciprocating screw rods and electric telescopic mechanisms can also be applied to this solution. This embodiment uses linear guide rails as an example.

[0054] At the same time, if Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the elastic top contact mechanism 3 is fixedly mounted on the transverse movement mechanism 2, and is driven by the transverse movement mechanism 2 to move transversely along the base 1. Specifically, the elastic top contact mechanism 3 includes a fixed frame 301, a guide sleeve 302, a variable diameter guide column 303, a spring 305 and a roller 304. Among them, the fixed frame 301 is a U-shaped frame body, which is fastened and mounted on the slider 202 of the linear guide rail by bolts. The guide sleeve 302 is integrally formed at the center of the inner side of the crossbar of the U-shaped frame body, and a through hole with a diameter smaller than the inner diameter of the guide sleeve 302 is provided in the center of the crossbar of the U-shaped frame body. The variable diameter guide column 303 includes a large diameter section and a small diameter section. The large diameter section is arranged in the guide sleeve 302, and the length of the large diameter section is smaller than the inner length of the guide sleeve 302, so that the variable diameter guide column 303 can be telescopically moved in the guide sleeve 302. The guide sleeve 302 is arranged along a square perpendicular to the base 1, and the spring 305 is fixed inside the guide sleeve 302 close to one end of the base 1, and the other end of the spring 305 is kept in contact with the large diameter section. In a natural state, the spring 305 supports the large diameter section to the end of the guide sleeve 302 away from the base 1. When the variable diameter guide post 303 is pressed and moves toward the inside of the guide sleeve 302, the spring 305 is compressed. When the external force exerting pressure on the variable diameter guide post 303 disappears, the spring 305 drives the variable diameter guide post 303 to return to its original position. During this process, in order to keep the variable diameter guide column 303 in linear motion, an insertion rod 306 is integrally formed at the inner bottom of one end of the guide sleeve 302 close to the base 1, and a socket 307 is provided at the large diameter section. In a natural state, the insertion rod 306 is inserted into the socket 307 and is located at the opening of the socket 307. When the variable diameter guide column 303 is pressed and moves toward the inside of the guide sleeve 302, the insertion rod 306 is gradually inserted into the socket 307, thereby playing a guiding role and preventing the variable diameter guide column 303 from moving skewed.

[0055] In the above, the small diameter section and the large diameter section are integrally formed, and the small diameter section passes through the through hole in the middle of the U-shaped frame and extends to the outside of the guide sleeve 302. The end of the small diameter section is integrally formed with a U-shaped wheel frame, and a roller 304 is rotatably mounted on the wheel frame. During testing, after the elevator guide rail 6 to be tested is fixed to the base 1, the roller 304 contacts the testing surface 601 of the elevator guide rail to be tested.

[0056] It can be imagined that after the elevator guide rail 6 to be tested is fixed to the base 1, the traverse mechanism 2 drives the elastic contact mechanism 3 to move along the detection surface 601 of the elevator guide rail 6 to be tested. Since the roller 304 contacts the detection surface 601 of the elevator guide rail 6 to be tested, when the alignment of the elevator guide rail 6 to be tested is inconsistent, the roller 304 will move along the detection surface 601 of the elevator guide rail 6 to be tested and jump. Of course, in this detection process, in order to avoid the "false jump" of the roller 304 due to the uneven detection surface 601 of the elevator guide rail 6 to be tested, the length of the roller 304 in this embodiment should be close to or equivalent to the width of the detection surface 601 of the elevator guide rail 6 to be tested. Because the detection surface 601 of the elevator guide rail 6 to be tested will not have a relatively wide area of ​​unevenness, otherwise it will be found during quality inspection, so the length of the roller 304 is set to be longer, forming a longer contact surface with the elevator guide rail 6 to be tested, thereby avoiding the "false bounce" of the roller 304 due to the uneven detection surface 601 of the elevator guide rail 6 to be tested.

[0057] For more, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The marking assembly 4 includes a laser engraving head 401 and a marking plate 402. The side wall of the guide sleeve 302 is axially provided with a first vertical guide groove 308, and a first connecting arm 404 is provided in the first vertical guide groove 308. In a natural state, the first connecting arm 404 is located at the side of the first vertical guide groove 308 away from the base 1 and is parked. The first connecting arm 404 is integrally formed with the outer wall of the large diameter section of the variable diameter guide column 303, and the first connecting arm 404 moves up and down in the first vertical guide groove 308. An L-shaped seat is fixedly provided at one end of the first connecting arm 404 extending out of the guide sleeve 302, and the laser engraving head 401 is fixedly installed on the L-shaped seat. The marking plate 402 is installed on the side of the base 1 by bolts and corresponds to the laser engraving head 401. It can be imagined that after the elevator guide rail 6 to be tested is fixed to the base 1, the transverse movement mechanism 2 drives the elastic contact mechanism 3 to move along the detection surface 601 of the elevator guide rail 6 to be tested. Since the roller 304 contacts the detection surface 601 of the elevator guide rail 6 to be tested, when the straightness of the elevator guide rail 6 to be tested changes, the roller 304 will move along the detection surface 601 of the elevator guide rail 6 to be tested and jump. Since the laser engraving head 401 is fixed to the large diameter section of the reducing guide column 303 through the first connecting arm 404, when the reducing guide column 303 changes in extension and contraction, the laser engraving head 401 will jump synchronously, so that the line engraved on the marking plate 402 is not a straight line shape, so that the straightness of the elevator guide rail 6 to be tested can be judged.

[0058] In addition, it can be understood that during the measurement of the straightness of the elevator guide rail, the elevator guide rail may be deflected in two directions: Figure 6For example, when the elevator guide rail 6 to be tested is fixed to the base 1, the plane where the first connecting portion 101 and the elevator guide rail 6 to be tested are attached is used as the reference plane. The elevator guide rail 6 to be tested may be deflected toward the side close to the base 1 or away from the side of the base 1. Therefore, in order to achieve accurate measurement of deflection in two different directions, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a first arc groove 309 is provided in the middle of the first vertical guide groove 308 along the outer circumference of the guide sleeve 302 , and the first connecting arm 404 moves along the first vertical guide groove 308 , and the first connecting arm 404 can slide laterally and snap into the first arc groove 309 .

[0059] It can be imagined that a first arc groove 309 is set in the middle of the first vertical guide groove 308. During detection, the first connecting arm 404 is first moved to the side of the base 1 to the middle of the first vertical guide groove 308, the spring 305 is compressed, and the first connecting arm 404 is rotated laterally to be inserted into the first arc groove 309. Then, after the elevator guide rail 6 to be tested is fixed to the base 1, the roller 304 is fitted with the detection surface 601 of the elevator guide rail 6 to be tested, and then the first connecting arm 404 is withdrawn from the first arc groove 309. At this time, the elastic top contact mechanism 3 is driven to move along the detection surface 601 of the elevator guide rail 6 to be tested by the movement of the transverse movement mechanism 2. Under normal circumstances, if the alignment of the elevator guide rail 6 to be tested is consistent, the elastic top contact mechanism 3 will not jump during the movement, and the laser engraving head 401 will engrave a straight line on the marking plate 402. When the elevator guide rail 6 to be tested is deflected away from the base 1, the spring 305 will drive the elastic top contact mechanism 3 to move away from the base 1 under the action of elastic force, forming a broken line; similarly, when the elevator guide rail 6 to be tested is deflected toward the side close to the base 1, the elevator guide rail 6 to be tested will squeeze the elastic top contact mechanism 3 toward the side of the base 1, the spring 305 will be further compressed, and the elastic top contact mechanism 3 will move toward the side close to the base 1, forming a broken line. Therefore, by judging whether the engraved line is a straight line, the alignment of the elevator guide rail 6 to be tested can be judged, and the position to be searched and corrected can be obtained from the broken line position.

[0060] In addition, the collimation deviation is allowable within a certain range. Therefore, in this embodiment, in order to accurately determine whether the collimation after detection is within the allowable range, in a preferred embodiment, a group of upper and lower parallel limit marking lines 403 are provided on the marking plate 402, and the limit marking lines 403 are symmetrically arranged on both sides with the midpoint of the vertical line between the two. Under normal circumstances, the line engraved by the laser engraving head 401 is located between the two limit marking lines 403. When there is a broken line exceeding the limit marking lines 403 on both sides, it means that the collimation does not meet the requirements.

[0061] In the above, the laser engraving head 401 can be a domestically produced 500mw DC laser engraving head 401 with an input voltage of 12V. The figure does not show components for providing power, voltage and related supporting use.

[0062] In one embodiment, in order to facilitate the rotation of the variable diameter guide pillar 303, as shown in FIG. Figure 2 As shown, the guide sleeve 302 is provided with a second vertical guide groove 310 axially symmetrical with the first vertical guide groove 308, a second arc groove 311 is provided in the middle of the second vertical guide groove along the outer circumference of the guide sleeve 302, and the second arc groove 311 is opposite to the first arc groove 309 in direction, and the large diameter section of the variable diameter guide column 303 is provided with a lever 405 that slides in the second vertical guide groove 310, and the lever 405 can slide sideways and be clamped in the second arc groove 311. It can be imagined that the variable diameter guide column 303 can be conveniently rotated by the lever 405.

[0063] Based on the above content, the embodiment of the present application also provides a method for detecting the straightness of an elevator guide rail, comprising the steps of:

[0064] S1: Fix the elevator guide rail 6 to be tested on the base 1, and adjust the elastic contact mechanism 3 to fit the detection surface 601 of the elevator guide rail 6 to be tested;

[0065] S2: Start the traverse mechanism 2 to drive the elastic contact mechanism 3 to move along the detection surface 601 of the elevator guide rail 6 to be tested, and at the same time use the marking component 4 to move synchronously with the elastic contact mechanism 3 and draw a line;

[0066] S3: Determine the straightness of the elevator guide rail by checking whether there is a broken line on the line drawn by the marking component 4.

[0067] Specifically for each step:

[0068] The specific method for step S1 is:

[0069] The base 1 is fixed on the detection base 5 through the first connecting part 101, and the reducing guide column 303 is driven by the lever 405 to move to the side of the base 1 to the middle of the second vertical guide groove 310, and slides laterally into the second arc groove 311, and then the elevator guide rail 6 to be tested is fixed to the second connecting part 102 by bolts, and finally the lever 405 is retracted into the second vertical guide groove 310, so that the elastic contact mechanism 3 returns to the first vertical guide groove 308, and the roller 304 is in contact with the detection surface 601 of the elevator guide rail 6 to be tested.

[0070] The specific method for steps S2 and S3 is:

[0071] Start the transverse movement mechanism 2, and the elastic top contact mechanism 3 moves along the detection surface 601 of the elevator guide rail 6 to be tested under the drive of the transverse movement mechanism 2. Under normal circumstances, if the alignment of the elevator guide rail 6 to be tested is consistent, the elastic top contact mechanism 3 will not jump during the movement, and the laser engraving head 401 will engrave a straight line on the marking plate 402. When the elevator guide rail 6 to be tested is deflected away from the base 1, the spring 305 will drive the elastic top contact mechanism 3 to move away from the base 1 under the action of elastic force, forming a broken line; similarly, when the elevator guide rail 6 to be tested is deflected toward the side close to the base 1, the elevator guide rail 6 to be tested will squeeze the elastic top contact mechanism 3 toward the side of the base 1, the spring 305 will be further compressed, and the elastic top contact mechanism 3 will move toward the side close to the base 1, forming a broken line. Therefore, by judging whether the engraved line is a straight line, the alignment of the elevator guide rail 6 to be tested can be judged, and the position to be searched and corrected can be obtained from the broken line position. At the same time, by observing whether the engraved lines cross the limit marking lines 403 on both sides, it is determined whether the deflection of the elevator guide rail 6 to be tested is within the allowable range.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
