Description

Technical Field

[0001] This utility model belongs to the technical field of elevator testing equipment, specifically relating to a device for measuring the engagement depth between the elevator hall door slider and the sill groove. Background Technology

[0002] Current elevator cars typically use suspended sliding hall doors, with a sliding door slider 100 installed at the bottom. The sliding door slider 100 slides into the groove of the sill groove 200. During operation, the sliding door slider 100 slides along the sill groove, working in conjunction with the door pulley to guide and limit movement. When the sliding door slider 100 disengages from the sill groove 200 or the engagement depth with the sill groove 200 is insufficient, it can easily lead to accidents where people outside the hall door accidentally fall into the elevator shaft. Therefore, it is necessary to routinely check and adjust the engagement depth between the sliding door slider 100 and the sill groove 200 to ensure that the engagement depth is within the safe range.

[0003] And such Figure 1 As shown, the engagement point between the elevator hall door slider 100 and the sill groove 200 is relatively deep, and the distance between the elevator landing door and the ground is small. It is difficult for general measuring devices to reach deep into the sill groove for measurement. Even if they can be placed into the sill groove 200, the distance between the elevator hall door slider 100 and the edge of the hall door is relatively long, making it impossible to measure deeply. Existing technologies usually adopt two solutions. One is as shown in patent CN221302184, which adds a bent measuring hook to the traditional measuring ruler and inserts the hook part into the sill groove 200 for measurement. However, the hook length is still insufficient. The other is as shown in patent CN212475728, which uses a laser displacement sensor for measurement. However, the price range of the HG-C1100 laser displacement sensor used in this method is 980-1520, making the device very expensive and difficult to promote. Therefore, it is necessary to propose a new, simple and effective measuring device for the engagement depth of the elevator hall door slider 100 and the sill groove 200. Utility Model Content

[0004] The purpose of this invention is to provide a measuring device for the engagement depth of an elevator hall door slider and a sill groove, aiming to solve the technical problem in the prior art that it is inconvenient to directly measure the engagement depth of the elevator hall door slider and its sill groove because the engagement is deep inside the groove, and laser-type measuring tools are very expensive.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A slide rail, horizontally positioned within a sill groove; a measuring ruler, one end of which is perpendicular to and fixedly connected to the upper surface of the slide rail; a sliding platform, the lower surface of which is slidably connected to the upper surface of the slide rail to move closer to or further away from the elevator hall door slider, the end of the sliding platform closer to the elevator hall door slider being the front end, and the upper surface of the sliding platform being an inclined surface whose height decreases from back to front; a first positioning part, the first positioning part including a slider, the slider having a sliding surface for sliding on the inclined surface, and a side surface for engaging with the elevator hall door slider. The sliding surface and the inclined surface have a friction angle greater than the inclination angle of the inclined surface. The sliding surface is arranged perpendicular to the moving direction of the slide table, and its lower end is connected to the lower end of the sliding surface. The slide table can be driven to approach the elevator hall door slider, and the side of the elevator hall door slider pushes the slider to move up the inclined surface until the lower end of the elevator hall door slider abuts against the inclined surface, and the lower end of the slider is flush with the lower end of the elevator hall door slider. The slide table can be driven to approach the measuring ruler to obtain the height value of the lower end of the slider.

[0007] The beneficial effect of the sliding table and the first positioning part in this utility model is that the distance between the bottom of the elevator hall door slider and the bottom of the sill groove can be equivalently derived from the first positioning part. When the sliding table moves towards the elevator hall door slider, the side of the elevator hall door slider will contact the abutting surface of the first positioning part. When the sliding table continues to move forward, under the squeezing force generated after the elevator hall door slider and the first positioning part abut against each other, the first positioning part begins to slide upward along the slope until the bottom of the elevator hall door slider abuts against the slope of the sliding table, making the sliding table unable to move forward. At this time, the position of the bottom of the first positioning part (i.e., the first positioning part slider) is... The connection between the sliding surface and the contact surface represents the position of the lowest point of the elevator hall door slider. Using this method, the distance between the elevator hall door slider and the bottom of the sill groove can be equivalently derived. Since the friction angle between the sliding surface of the slider and the inclined surface is greater than the inclination angle of the inclined surface itself, the slider of the first positioning part can stay on the inclined surface without external force, maintaining its position pushed to the inclined surface by the elevator hall door slider. Therefore, when the slide table moves in the opposite direction to the measuring ruler, the height data of the lowest point of the slider of the first positioning part can be obtained by the measuring ruler, and then the engagement depth between the elevator hall door slider and the sill groove can be obtained.

[0008] Furthermore, the first positioning part also includes a locking block. The slide has an assembly cavity inside. The inclined surface has a strip-shaped sliding hole along its length that communicates with the assembly cavity. The lower part of the locking block is located in the assembly cavity and slides against the top surface of the assembly cavity. The upper part passes through the strip-shaped sliding hole and is fixedly connected to the sliding surface of the slider.

[0009] The further beneficial effects of this utility model are: by utilizing the sliding relationship between the locking block and the strip-shaped sliding hole, the stability of the sliding of the first positioning part is ensured, and the first positioning part is guided. At the same time, the lower part of the locking block slides against the inner top surface of the assembly cavity to limit the movement and prevent the slider of the first positioning part from disengaging from the inclined surface of the slide table.

[0010] Furthermore, it also includes a threaded rod, which is located inside the assembly cavity and arranged parallel to the inclined surface. Its two ends are respectively rotatably connected to the inner wall of the assembly cavity. The middle of the locking block has a through threaded hole, and the locking block is threadedly connected to the threaded rod through the threaded hole.

[0011] A further beneficial effect of this utility model is that, through the threaded connection between the threaded rod and the threaded hole of the locking block, the self-locking effect of the thread is utilized to further ensure that the first positioning part slides down without being affected by the force of the elevator hall door slider, thereby affecting the measurement accuracy.

[0012] Furthermore, the first positioning part also includes an L-shaped first indicator needle, which is located on the side of the slider near the measuring ruler. Its first segment is perpendicular to and fixedly connected to the lower end of the side of the slider, and its second segment is arranged in the horizontal direction.

[0013] A further beneficial effect of this utility model is that by setting a first indicator needle, the first segment of which plays a positioning role, the slide moves along the slide rail toward the measuring ruler. When the first segment comes into contact with the side of the measuring ruler, the second segment in the horizontal direction replaces the lower end of the slider of the first positioning part and aligns with the scale line, making it convenient to observe and read the value with the naked eye.

[0014] Furthermore, the length of the first segment of the first indicator needle is adapted to the thickness of the measuring ruler body.

[0015] A further beneficial effect of this invention is that by controlling the length of the first segment of the first indicator needle, the second segment is made closer to the surface of the scale when reading, making it easier to read and avoiding incorrect readings due to insufficient horizontal viewing angle.

[0016] Furthermore, it also includes a second positioning part, which is slidably connected to the measuring ruler, and its lower end can abut against the ground aligned with the groove opening of the sill.

[0017] A further beneficial effect of this utility model is that, by utilizing the characteristic that the lower end of the second positioning part can be aligned with the ground surface at the opening above the sill groove, and by using the scale on the measuring ruler to display the position of the uppermost part of the sill groove, the engagement depth between the lowermost part of the second positioning part and the lowermost part of the first positioning part can be directly expressed.

[0018] Furthermore, a U-shaped groove is provided on the side of the second positioning part, and the second positioning part is slidably connected to the measuring ruler along its length direction through the U-shaped groove. A second indicator needle is provided at the lower end of the U-shaped groove.

[0019] Further beneficial effects of this utility model are: the first positioning part is driven to slide up and down along the measuring ruler by using a U-shaped slide groove, the U-shaped opening makes it convenient for the observer to take readings, and the second indicator needle at the lower end of the U-shaped slide groove can help the observer to quickly position the object.

[0020] Furthermore, it also includes an operating handle, the mounting end of which is fixedly connected to the rear end of the slide, and the operating end of which is higher than the upper opening of the sill groove.

[0021] Further beneficial effects of this utility model are: by setting an operating handle to extend the maximum sliding distance of the slide table, it can accommodate elevator hall door sliders with deeper engagement positions. At the same time, the operating end of the operating handle is higher than the upper opening of the sill groove, which facilitates operation by surveyors.

[0022] Furthermore, the minimum scale on the measuring ruler is 0.5mm, and the width of the slide rail along its length remains constant and is less than or equal to 50mm.

[0023] Further beneficial effects of this utility model are: by limiting the scale to 0.5mm, the overall measurement accuracy of the device is improved, and the size of the slide rail is limited to facilitate the overall lowering of the device into the sill groove. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] As shown in the figure, this embodiment provides a measuring device for the engagement depth of an elevator hall door slider 100 and a sill groove 200, including: a slide rail 1, a measuring ruler 2, a slide table 3, and a first positioning part 4. The measuring ruler 2 is longer than the depth of the sill groove 200 corresponding to the elevator hall door slider 100, specifically 200mm, and is vertically arranged. Its lowest end abuts against the bottom of the sill groove 200. One side has scale lines, and the side with scale lines is set as the front of the measuring ruler 2. The slide rail 1 is perpendicular to and fixedly connected to the lower back of the measuring ruler 2. The slide rail 1 is used to be placed at the bottom of the sill groove 200. The slide table 3 is shaped like a wedge, and its bottom surface is slidably connected to the upper surface of the slide rail 1. It is used to move closer to or away from the elevator hall door slider 100. The inclined surface of the slide table 3 is arranged relative to the elevator hall door slider 100. The direction in which the tip of the slide table 3 points forward, i.e., the sliding direction of the slide table 3 towards the elevator hall door slider 100, is forward. The first positioning part 4 includes a slider 401. The slider 401 has a sliding surface 4011 for sliding on the inclined surface and an abutting surface 4012 for abutting against the side of the elevator hall door slider 100. The friction angle between the sliding surface 4011 and the inclined surface is greater than the inclination angle of the inclined surface, so that the slider 401 of the first positioning part 4 can stay on the inclined surface without external force. The abutting surface 4012 is arranged perpendicular to the moving direction of the slide table 3, and its lower end is connected to the lower end of the sliding surface 4011. In this embodiment, the slider 401 of the first positioning part 4 is a triangular block, one side of which is slidably connected to the inclined surface, and the other side is arranged vertically to abut against the side of the elevator hall door slider 100.

[0039] The working principle of the slide table 3 and the first positioning part 4 is as follows: when power is provided to the slide table 3, the slide table 3 moves towards the elevator hall door slider 100 until the front end of the slide table 3 reaches the edge of the elevator hall door slider 100. At this time, the bottom end of the elevator hall door slider 100 will simultaneously contact the second measuring part. Under the action of the power and the squeezing force generated after the elevator hall door slider 100 and the first positioning part 4 come into contact, the first positioning part 4 begins to slide upward along the slope until the bottom end of the elevator hall door slider 100 comes into contact with the slope of the slide table 3. The slide table 3 can no longer advance. At this time, the position of the bottom end of the first positioning part 4 represents the position of the bottom end of the elevator hall door slider 100. Using this method, the distance between the bottom of the elevator hall door slider 100 and the bottom of the sill groove 200 can be extended by an equal amount. Then, the slide table 3 is driven in a direction to approach the measuring ruler 2. The scale line corresponding to its bottom end position can represent the distance between the bottom of the elevator hall door slider 100 and the bottom of the sill groove 200.

[0040] In some embodiments, the slide table 3 is hollow inside, and a strip-shaped sliding hole 301 is formed on the inclined surface along its length. The lower end of the first positioning part 4 has a protruding locking block 402. The locking block 402 extends into the sliding hole 301 and slides in connection with the sliding hole 301. The two sides of the lower end of the locking block 402 have protruding limiting parts that abut against the inner top surface of the slide table 3. In this embodiment, the first positioning part 4 is installed on the slide table 3 by the locking block 402 cooperating with the sliding hole 301, and the limiting parts are used to prevent the first positioning part 4 from disengaging from the inclined surface of the slide table 3.

[0041] Based on the previous embodiment, a threaded rod 302 is also included. The threaded rod 302 is located inside the slide table 3 and arranged parallel to the inclined plane. Its two ends are rotatably connected to the slide table 3. The middle part of the locking block 402 has a through threaded hole along the axial direction of the threaded rod 302 and is threadedly connected to the threaded rod 302. In this embodiment, the threaded connection between the threaded rod 302 and the threaded hole of the locking block 402 utilizes the self-locking effect of the thread to further ensure that the measurement accuracy is not affected when the first positioning part 4 slides down without being affected by the force of the elevator hall door slider 100.

[0042] In some embodiments, the side of the slider 401 of the first positioning part 4 can slide and fit against the side of the measuring ruler 2 away from its scale line. The structure of this embodiment can ensure that the lower end of the first positioning part 4 is closer to the scale line of the measuring ruler 2 in space, avoiding reading errors caused by the viewing angle not being aligned with the scale line.

[0043] Based on the previous embodiment, an L-shaped first indicator 403 is also included. The first segment of the first indicator 403 is perpendicularly and fixedly connected to the lower end of the side of the slider 401 near the measuring scale 2, and the second segment is arranged horizontally. In this embodiment, by setting the first indicator 403, its first segment plays a positioning role. The slide 3 moves along the slide rail 1 towards the measuring scale 2. When the first segment abuts against the side of the measuring scale 2, its second segment in the horizontal direction replaces the lower end of the first positioning part 4 and aligns with the scale line, making it convenient to observe and read the value with the naked eye.

[0044] Based on the previous embodiment, the length of the first segment of the first indicator needle 403 is adapted to the thickness of the measuring ruler 2. In this embodiment, by controlling the length of the first segment of the first indicator needle 403, the second segment is made closer to the surface of the measuring ruler 2 when reading, which facilitates reading and avoids reading errors caused by the viewing angle not being aligned with the second segment of the first indicator needle 403.

[0045] In other embodiments, a second positioning part 5 is also included. The second positioning part 5 is slidably connected to the measuring ruler 2, and its lower end can abut against the ground aligned with the opening of the sill groove 200. In this embodiment, by additionally setting the second positioning part 5, and utilizing the characteristic that its lower end can be flush with the ground aligned with the opening above the sill groove 200, the scale on the measuring ruler 2 displays the position of the uppermost part of the sill groove 200. At this time, the engagement depth between the scale corresponding to the lowermost part of the second positioning part 5 and the scale corresponding to the lowermost part of the first positioning part 4 can be directly expressed, making the measurement more convenient.

[0046] Based on the previous embodiment, the second positioning part 5 has a U-shaped groove 501 on its side. The side of the measuring ruler 2 away from the scale line is slidably connected to the U-shaped groove 501, and a second indicator needle 502 is provided at the lower end of the U-shaped groove 501. In this embodiment, the U-shaped groove 501 is used to drive the second positioning part 5 to slide up and down along the measuring ruler 2. The U-shaped opening facilitates reading by the observer, and the second indicator needle 502 at the lower end of the groove assists the observer in reading the measurement.

[0047] In some embodiments, an operating handle 6 is also included. One end of the operating handle 6 is fixedly connected to the rear end of the slide table 3, and the other end is the operating end, which is higher than the upper opening of the sill groove 200. Specifically, the operating handle 6 includes a horizontal push rod and a vertical operating rod. One end of the push rod is fixedly connected to the middle of the rear end of the slide table 3, and the lower end of the operating rod is perpendicular to and fixedly connected to the other end of the push rod. The installation position of the push rod and the length of the operating rod satisfy the condition that the upper end of the operating rod is above the upper opening of the sill groove 200. The upper end of the operating rod is also fitted with a rubber anti-slip sleeve. In this embodiment, the maximum sliding distance of the slide table 3 is extended by setting the operating handle 6 to accommodate the elevator hall door slider 100 with a deeper engagement position. At the same time, the operating end of the operating handle 6 is higher than the upper opening of the sill groove 200, which facilitates operation by surveyors.

[0048] The minimum graduation on the measuring ruler 2 of this invention is 0.5mm, and the width of the slide rail 1 along its length remains constant and is less than or equal to 50mm. By limiting the graduation to 0.5mm, the overall measurement accuracy of the device is improved, and the size of the slide rail 1 is limited to facilitate the overall placement of the device into the sill groove 200.

[0049] The specific method of using this utility model is as follows:

[0050] First, lay the guide rail flat in the sill groove 200. Then, slide the second positioning part 5 until its lower end abuts against the ground above the sill groove 200. Read the scale line corresponding to the second indicator needle 502 at the lower end of the second positioning part 5. Then, use the operating handle 6 to control the slide table 3 to move along the guide rail toward the elevator hall door slider 100. The bottom of the elevator hall door slider 100 will push the slider 401 of the first positioning part 4 to slide along the inclined surface of the slide table 3 until the bottom of the elevator hall door slider 100 abuts against the inclined surface of the slide table 3, restricting the movement of the slide table 3. At this time, the lower end of the slider 401 corresponds to the elevator hall. The door slider 100 is positioned at its lowest point. Then, the operating handle 6 is used to retract the slide table 3. During this process, because the friction angle between the sliding surface of the slider 401 and the inclined plane is greater than the angle of the inclined plane itself, and the threaded rod 302 and the threaded hole in the locking block 402 are self-locking, the slider 401 remains stationary on the inclined plane. The slide table 3 gradually moves towards the measuring ruler 2 until the first segment of the first indicator needle 403 abuts against the side of the measuring ruler 2. Then, the scale line pointed to by the second segment of the first indicator needle 403 is read. The length between the two scale lines is the engagement depth between the elevator hall door slider 100 and the sill groove 200.

[0051] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
