Description

Technical Field

[0001] This invention relates to the technical field of positioning devices, and in particular to an elevator landing door positioning device. Background Technology

[0002] Elevator landing doors are safety doors between elevators and floors, primarily used to ensure the safe entry and exit of passengers. They work in conjunction with elevator doors through mechanical or electronic devices to prevent accidents caused by doors not closing during elevator operation. The design of landing doors must not only meet safety standards but also consider aesthetics and convenience, and they are widely used in various types of passenger elevators and freight elevators.

[0003] When installing elevator landing doors, it is generally necessary to first drill holes in the inner wall of the elevator shaft to facilitate the accurate installation of the sill track. Then, the door frame and door operator are installed in sequence. After installation, it is necessary to measure with a ruler to ensure that each component is installed within the specified range.

[0004] However, ensuring accurate drilling positions and distance measurements is crucial during elevator door installation. Currently, commonly used tools include steel rulers or tape measures with levels and plumb bobs. While these tools can complete the measurement, determining distances often requires multiple point measurements, which is both time-consuming and inconvenient. Furthermore, traditional measurement methods are easily affected by human factors, which may lead to errors and are quite inconvenient. Summary of the Invention

[0059] The technical effects and advantages of this invention are as follows:

[0060] (1) The present invention utilizes a combination of a mobile frame, a support mechanism, an adjustment mechanism, a dotting and measuring mechanism, and a measuring plate. The support mechanism adjusts the level of the mobile frame, and the adjustment mechanism adjusts the position of the dotting and measuring mechanism. By changing the shape of the dotting and measuring mechanism, the object can be dotted or installed at the required distance. At the same time, the measuring plate facilitates the measurement of the distance after installation, improving the overall accuracy of measurement and installation, and enhancing work efficiency and measurement quality.

[0061] (2) This invention utilizes a combination of a fixed plate, a rotating plate, a clamping and marking component, a positioning component, and a measuring component. The positioning component fixes the clamping and marking component in different states, allowing the clamping and marking component to clamp the sill track and other components to be installed when the fixed plate and the displacement rod are on the same horizontal line. The clamping distance can be determined by the measuring component during clamping, facilitating installation. When the fixed plate and the displacement rod are perpendicular to each other, the clamping and marking component can synchronously mark the required positions under the pull of the first pull rod, and the marking distance can also be measured by the measuring component. The rotating plate design allows the clamping and marking component to flexibly adjust its angle to adapt to different installation environments and needs, enabling the equipment to be used not only for installation on horizontal planes but also for effective marking on vertical planes, further expanding its application range. The high-precision sensor of the measuring component can provide real-time feedback on the clamping distance and marking position, ensuring that users can quickly obtain the required data and reducing the errors that may be caused by manual measurement in traditional methods. This design greatly improves work efficiency and reduces repeated adjustments and inspections during the installation process.

[0062] (3) The present invention utilizes a combination of a laser rangefinder transmitter, a laser rangefinder receiver, a linkage plate, a telescopic rod, a third compression spring, a pressing plate, a pressing rod, a sliding block, and a rotating frame. When the fixed plate is in a rotating state, the laser rangefinder transmitter and the laser rangefinder receiver rotate 90° under the pressing and pushing of the pressing plate. This enables the conversion between measuring the distance between clamping plates and measuring the distance between measuring plates. Users can easily obtain the required measurement data, reducing the cumbersome operations common in traditional measuring tools and greatly improving work efficiency.

[0063] (4) The present invention utilizes a combination of screw, support plate, support frame and caster wheel to make the mobile frame reversible, which is convenient for positioning and installing elevator doors, and can also serve as a material conveying device on the construction site. It is a dual-purpose device, suitable for various construction sites, and meets the diverse needs of users. Attached Figure Description

[0075] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] This invention provides, for example Figure 1-10 The elevator landing door positioning device shown includes a movable frame 1, a support mechanism 2, an adjustment mechanism 3, a marking and measuring mechanism 4, and a measuring plate 5. The support mechanism 2 is mounted on the movable frame 1 and is used to adjust the position of the movable frame 1. The adjustment mechanism 3 is mounted on the movable frame 1. The marking and measuring mechanism 4 is movable on the movable frame 1 via the adjustment mechanism 3 and is used for marking, clamping, and measuring distances. The measuring plate 5 is mounted on the marking and measuring mechanism 4 and is located at the edge of the fixed plate 461, which facilitates the measurement of some small distances and the measurement of the distances required after the elevator is completed, so as to observe whether it meets the requirements.

[0077] Specifically, the support mechanism 2 includes a screw 21, a support plate 22, a support frame 23, and casters 24. The bottom of the movable frame 1 is provided with equidistant adjustment slots. One end of the screw 21 is threadedly connected to the inner cavity of the adjustment slot. The support plate 22 is fixedly connected to the bottom end of the screw 21. The position of each support plate 22 can be finely adjusted by the screw 21. With the help of multiple spirit levels 7, the entire movable frame 1 can be kept in a horizontal state during use, which is convenient for drilling and positioning. The support frame 23 is symmetrically fixedly connected to the top of the movable frame 1. The casters 24 are symmetrically rotated and installed inside the support frame 23. By flipping the movable frame 1, the casters 24 contact the ground, and the entire device can be used as a transportation device to bundle and transport some materials. It is a dual-purpose device that is easy to use.

[0078] Specifically, the adjustment mechanism 3 includes a motor 31, a drive rod 32, a slider 33, an adjustment frame 34, and a first bidirectional screw 35. The motor 31 is fixedly installed on the top of the movable frame 1 and is electrically connected to an external power source via an external switch. The end of the drive rod 32 is rotatably connected to the inner wall of the movable frame 1, and the output end of the motor 31 is drively connected to one end of the drive rod 32. The slider 33 and the drive rod 32 form a screw drive, and the motor 31 drives the drive rod 32 to rotate in both directions, thereby allowing the slider 33 to rotate. The displacement inside the movable frame 1 drives the adjustment frame 34 to move back and forth in the vertical direction. The adjustment frame 34 is fixedly connected to the outer wall of the slider 33. The end of the first bidirectional screw 35 is rotatably inserted into the inner wall of the adjustment frame 34. The dotting and measuring mechanism 4 is displaced by the first bidirectional screw 35, and then rotated by the first bidirectional screw 35, so that the dotting and measuring mechanisms 4 inside the adjustment frame 34 can move closer or further away from each other, so that drilling and dotting at different distances or distance measurement can be performed as needed.

[0079] Specifically, the dot-marking measuring mechanism 4 includes a sleeve 41, a fixed rod 42, a displacement rod 43, a first pull rod 44, a first compression spring 45, and a rotating measuring assembly 46. The sleeve 41 is symmetrically arranged inside the adjusting frame 34, and the sleeve 41 and the first bidirectional screw 35 form a screw drive. One end of the fixed rod 42 is slidably inserted into the inner cavity of the sleeve 41, and the other end of the fixed rod 42 is slidably inserted into the inner cavity of the displacement rod 43. One end of the displacement rod 43 is slidably inserted into the inner cavity of the sleeve 41. The first pull rod 44 is fixedly connected to the top end of the displacement rod 43. The top end of the sleeve 41 has a first groove communicating with the inner cavity of the sleeve 41. The first compression spring... 45 is sleeved on the outer wall of the fixed rod 42. One end of the first compression spring 45 is fixedly connected to the inner wall of the sleeve 41, and the other end of the first compression spring 45 is fixedly connected to the displacement rod 43. The rotation measuring component 46 is set at the other end of the displacement rod 43. The first compression spring 45 is always in a compressed state, so that it can provide a stable elastic force to the displacement rod 43, so that the displacement rod 43 can push the rotation measuring component 46 to the farthest point. This makes it convenient to pull the displacement rod 43 through the first pull rod 44 to perform the drilling and marking operation. After the marking is completed, it can also recover under the elastic force of the first compression spring 45, which is convenient for use.

[0080] Furthermore, the rotation measuring assembly 46 includes a fixed plate 461, a rotating plate 462, a clamping and marking assembly 463, a positioning assembly 464, and a measuring assembly 465. The fixed plate 461 is disposed at the other end of the displacement rod 43. One end of the rotating plate 462 is fixedly connected to the fixed plate 461. The other end of the displacement rod 43 has a rotating groove. The rotating plate 462 is rotatably inserted and connected to the inner cavity of the rotating groove through a rotating shaft. The clamping and marking assembly 463 is disposed inside the fixed plate 461 and is used to clamp elevator parts. The positioning assembly 464 is disposed at the other end of the displacement rod 43 and is used for multi-point positioning of the rotating plate 462. The measuring assembly 465 is disposed inside the fixed plate 461 and is used to measure the marking distance and the distance between the measuring plates 5. By using the positioning assembly 464 to fix the clamping and marking assembly 463 in different states, the clamping and marking assembly 463 can be used to fix the sill rail to be installed when the fixed plate 461 and the displacement rod 43 are on the same horizontal line. The device clamps other components together, and the clamping distance can be determined by the measuring component 465 during clamping, facilitating installation. When the fixed plate 461 and the displacement rod 43 are perpendicular to each other, the clamping and marking component 463 can synchronously mark the required marking positions under the pull of the first pull rod 44, and the marking distance can also be measured by the measuring component 465. The design of the rotating plate 462 allows the clamping and marking component 463 to flexibly adjust its angle to adapt to different installation environments and needs, enabling the device to be used not only for installation on horizontal surfaces, but also for effective marking on inclined or vertical surfaces, further expanding its application range. The high-precision sensor of the measuring component 465 can provide real-time feedback on the clamping distance and marking position, ensuring that users can quickly obtain the required data and reducing the errors that may be caused by manual measurement in traditional methods. This design greatly improves work efficiency and reduces repeated adjustments and inspections during the installation process.

[0081] Furthermore, the clamping and marking assembly 463 includes a second bidirectional screw 4631, a clamping plate 4632, a limiting block 4633, an anti-slip pad 4634, a marker 4635, and a protective cover 4636. A groove is formed at the bottom end of the fixing plate 461. The end of the second bidirectional screw 4631 is rotatably inserted into the inner wall of the groove. One end of the clamping plate 4632 is symmetrically positioned inside the groove. The clamping plate 4632 and the second bidirectional screw 4631 form a screw drive. Rotation of the second bidirectional screw 4631 allows the clamping plates 4632 to move closer or further apart, thereby clamping the elevator sill rail for convenient subsequent installation. It can also clamp other components for easy installation. Limiting grooves are formed on both sides of the inner wall of the groove. The limiting block 4633 is slidably inserted into the inner cavity of the limiting groove. The limiting block 4633 and the clamping plate 4632... The fixed connection and the limiting block 4633 limit the clamping plate 4632, so that the clamping plate 4632 can only move back and forth along the direction of the limiting groove under the rotation of the second bidirectional screw 4631. The anti-slip pad 4634 is embedded in the bottom of the clamping plate 4632 and is used to contact the elevator door parts. The anti-slip pad 4634 increases the friction between the clamping plate 4632 and the clamped part, making the clamping effect better. The bottom end of the clamping plate 4632 has a mounting groove. The marker pen 4635 is threadedly connected to the inner cavity of the mounting groove. The protective cover 4636 is threadedly connected to the bottom of the clamping plate 4632 and is used to isolate the marker pen 4635. By opening the protective cover 4636, the marker pen 4635 can be exposed, so that the clamping plate 4632 can have the function of marking points under the pull of the first pull rod 44, which is convenient for use.

[0082] Furthermore, the positioning assembly 464 includes a positioning rod 4641, a second pull rod 4642, and a second compression spring 4643. A positioning groove is formed on one side of the inner wall of the rotating groove. One end of the positioning rod 4641 is slidably inserted into the inner cavity of the positioning groove. A positioning hole is formed on the outer wall of the rotating plate 462. The other end of the positioning rod 4641 cooperates with the inner cavity of the positioning hole. The second pull rod 4642 is fixedly connected to the bottom end of the positioning rod 4641. A second pull groove communicating with the positioning groove is formed at the bottom end of the displacement rod 43. The second compression spring 4643 is disposed inside the positioning groove. One end of the second compression spring 4643 is fixedly connected to the positioning rod 4641, and the other end of the second compression spring 4643 is fixedly connected to the inner wall of the positioning groove. The second compression spring 4643 is always in a compressed state, thus providing a stable elastic force to the positioning rod 4641. This ensures that the positioning rod 4641 always extends and fits against the bottom end of the rotating plate 462, limiting the rotation plate 462 and keeping the fixed plate 461 and the displacement rod 43 on the same horizontal line. When it is necessary to adjust the state of the fixed plate 461, the positioning rod 4641 can be pulled by the second pull rod 4642, thereby flipping the fixed plate 461 into a vertical state. This allows the positioning rod 4641 to engage with the positioning hole, facilitating the drilling and marking of the sill rail mounting bracket on the inner wall of the elevator shaft by fixing the fixed plate 461 in a vertical state.

[0083] Furthermore, the measuring component 465 includes a laser rangefinder transmitter 4651, a laser rangefinder receiver 4652, a linkage plate 4653, a telescopic rod 4654, a third compression spring 4655, a compression plate 4656, a compression rod 4657, a sliding block 4658, and a rotating frame 4659. The laser rangefinder transmitter 4651 is rotatably connected to the top of one of the clamping plates 4632 via a rotating shaft, and the laser rangefinder receiver 4652 is rotatably connected to the top of the other clamping plate 4632 via a rotating shaft. There are two laser rangefinders 4651 and 4652, which are staggered at the four corners when viewed from above. This allows the required measurement data to be calculated based on the measurements taken by the laser rangefinders 4651 and 4652, and then fed back to the display screen 6. Under the pressure of the linkage plate 4653, the laser rangefinders 4651 and 4652 can rotate 90°, thus enabling… The distance measurement between clamping plates 4632 and the spacing measurement between measuring plates 5 are now interchangeable, allowing users to easily obtain the required measurement data. This reduces the cumbersome operations common in traditional measuring tools and greatly improves work efficiency. Limiting rods 8 are fixedly connected to the bottom ends of both the laser rangefinder 4651 and the laser range receiver 4652. Arc-shaped grooves for sliding the limiting rods 8 are provided at the top ends of both clamping plates 4632. The angle of these grooves is a quarter-circle arc, facilitating the movement of the laser rangefinder 4651. 1. The rotation of the laser rangefinder receiver 4652 is limited. A displacement groove is provided at the top of the inner wall of the groove. The linkage plate 4653 is set inside the displacement groove. One end of the telescopic rod 4654 is fixedly connected to the inner wall of the displacement groove at equal distances. The other end of the telescopic rod 4654 is fixedly connected to the linkage plate 4653 at equal distances. The third compression spring 4655 is sleeved on the outside of the telescopic rod 4654. One end of the third compression spring is fixedly connected to the linkage plate 4653. The other end of the third compression spring 4655 is fixedly connected to the inner wall of the displacement groove. A through groove communicating with the positioning hole is provided on one side of the inner wall of the displacement groove. The extrusion plate 4656 is slidably inserted into the inner cavity of the through groove. One end of the extrusion plate 4656 has an inclined surface and an extrusion groove. One end of the extrusion rod 4657 is fixedly connected to the linkage plate 4653, and the other end of the extrusion rod 4657 is slidably inserted into the inner cavity of the extrusion groove. A sliding groove is provided at the bottom end of the linkage plate 4653, and a sliding block 4658 is slidably inserted into the inner cavity of the sliding groove. The cross-section of the sliding block 4658 is T-shaped. One end of the rotating frame 4659 is rotatably connected to the laser rangefinder transmitter 4651 and the laser rangefinder receiver 4652, respectively. The other end of the rotating frame 4659 is rotatably connected to the sliding block 4658. The third compression spring 4655 is always in a compressed state, so that the linkage plate 4653 can be closely attached to the direction of the measuring plate 5. At this time, the rotating frame 4659 is in the position of Figure 6In the state shown, the laser rangefinder transmitter 4651 and laser rangefinder receiver 4652 inside the same fixed plate 461 are not in a cooperative state, but are in a cooperative state with those inside another fixed plate 461. At this time, the distance between the clamping plates 4632 can be measured. When measuring the distance through the measuring plate 5, the distance between the edge of the clamping plate 4632 and the fixed plate 461 can be subtracted, which is the spacing between the measuring plates 5. When pre-positioning the drilling, half the thickness of the clamping plate 4632 can be added to the measurement result, which is the required drilling distance. This addition and subtraction operation can be implemented in the control system inside the display screen 6. When the fixed plate 461 and the displacement rod 43 are in a vertical state, the positioning rod 4641 can press the pressing plate 4656, thereby allowing displacement through the pressing rod 4657, causing the linkage plate 4653 to pull the rotating frame 4659, and causing the laser rangefinder transmitter 4651 and laser rangefinder receiver 4652 to be in a cooperative state. Figure 7 In the state shown, the laser rangefinder transmitter 4651 and laser rangefinder receiver 4652 inside the same fixed plate 461 are in a connected state, so that the distance to the center position of the clamping plate 4632 can be measured, which facilitates the measurement of the drilling distance and displays it on the display screen 6.

[0084] Furthermore, a display screen 6 is fixedly installed on the outer wall of the movable frame 1 to display measurement data, and a spirit level 7 is symmetrically fixedly installed on the top of the movable frame 1.

[0086] When it is necessary to install the landing door sill track, the entire device can be placed at the landing door entrance, and the position of the movable frame 1 can be finely adjusted by screw 21 so that the multiple spirit levels 7 on the movable frame 1 are all in a horizontal state.

[0087] After adjusting the level, the motor 31 drives the drive rod 32 to rotate, causing the slider 33 to move the adjusting frame 34 to a suitable height. Then, the first bidirectional screw 35 rotates, causing multiple sleeves 41 to move the fixed plate 461 on the displacement rod 43. At this time, the fixed plate 461 and the displacement rod 43 are on the same horizontal line. The display screen 6 shows that the measured distance is exactly the distance between the two clamping plates 4632. By adding half the thickness of the clamping plates 4632, the drilling and marking positions of the sill mounting frame can be pre-marked.

[0088] Then, by pulling the second pull rod 4642, the positioning rod 4641 is housed inside the positioning groove. At this time, the fixing plate 461 can be rotated by the rotating plate 462 to be perpendicular to the displacement rod 43. Then, the second pull rod 4642 is released, allowing the positioning rod 4641 to interlock with the positioning hole. This fixes the fixing plate 461 in a vertical position while simultaneously pressing the pressing plate 4656. The pressing rod 4657 moves within the pressing groove, causing the linkage plate 4653 to pull the rotating frame 4659, and causing the laser rangefinder transmitter 4651 and laser range receiver 4652 to rotate. The laser rangefinder 4651 and laser rangefinder 4652 inside the same fixed plate 461 are in a connected state, so that the distance to the center position of the clamping plate 4632 can be measured, which facilitates the adjustment of the drilling and marking distance. The measured value is displayed on the display screen 6. At this time, the protective cover 4636 can be unscrewed to expose the marker pen 4635. Under the pull of the first pull rod 44, the marker pen 4635 can mark the inner wall of the elevator shaft. After the drilling operation is completed and the sill rail mounting frame is installed, the sill rail can be clamped by the clamping plate 4632 to complete the installation of the elevator landing door sill rail.
