Description

Technical Field

[0001] The present invention relates to the technical field of positioning devices, and particularly to an elevator landing door positioning device. Background Technique

[0002] The elevator landing door is a safety door between the elevator and the floor, mainly used to ensure the safe entry and exit of passengers. It works in coordination with the elevator door through mechanical or electronic devices to prevent accidents caused by the door not being closed during elevator operation. The design of the landing door not only needs to meet safety standards but also consider aesthetics and convenience, and is widely used in various passenger elevators and freight elevators;

[0003] When installing the elevator landing door, generally, the inner wall of the elevator shaft needs to be marked and drilled first to facilitate the accurate installation of the sill track, and then the door pocket and door machine 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, during the installation process of the elevator landing door, ensuring accurate drilling positions and measuring distances is crucial. Currently, common tools include steel rulers or tape measures in combination with spirit levels and plumb bobs. Although these tools can complete the measurement, when determining distances, multiple-point measurements are often required, which is time-consuming and not very convenient. In addition, traditional measurement methods are easily affected by human factors during operation, which may lead to errors and are rather inconvenient. Summary of the Invention

[0059] The technical effects and advantages of the present invention:

[0060] (1) The present invention utilizes a setting method in which a moving frame, a support mechanism, an adjustment mechanism, a dotting measurement mechanism, and a measurement plate cooperate with each other. The support mechanism adjusts the levelness of the moving frame, so that the position of the dotting measurement mechanism can be adjusted through the adjustment mechanism, and the form of the dotting measurement mechanism can be changed, so as to dot or install an article according to the required positioning distance. At the same time, the setting of the measurement plate also facilitates the measurement of the distance after installation, improving the overall measurement and installation accuracy, and enhancing the work efficiency and measurement quality;

[0061] (2) The present invention utilizes a setting method in which a fixed plate, a rotating plate, a clamping and dotting assembly, a positioning assembly, and a measurement assembly cooperate with each other. The positioning assembly fixes the clamping and dotting assembly in different states. When the clamping and dotting assembly is on the same horizontal line as the fixed plate and the displacement rod, it can clamp the landing door track and other components that need to be installed. And when clamping, the clamping distance can be determined by the measurement assembly, which is convenient for installation processing. When the fixed plate and the displacement rod are in a mutually perpendicular state, the clamping and dotting assembly can complete synchronous dotting of the position to be dotted under the pulling of the first pull rod, and the dotting distance can also be measured by the measurement assembly. The design of the rotating plate enables the clamping and dotting assembly to flexibly adjust the angle to adapt to different installation environments and requirements, so that the device can not only be used for installation on a horizontal plane, but also perform effective dotting on a vertical plane, further expanding its application range. The high-precision sensor of the measurement assembly can real-time feedback the clamping distance and dotting position, ensuring that users can quickly obtain the required data, reducing the errors that may be caused by manual measurement in the traditional method. This design greatly improves the work efficiency and reduces the repeated adjustment and inspection during the installation process;

[0062] (3) The present invention utilizes a setting method in which a laser distance measuring transmitter, a laser distance measuring receiver, a linkage plate, a telescopic rod, a third compression spring, an extrusion plate, an extrusion rod, a sliding block, and a rotating frame cooperate with each other. When the fixed plate is in a rotating and changing state, the laser distance measuring transmitter and the laser distance measuring receiver rotate 90° under the extrusion and push of the extrusion plate, so as to realize the mutual conversion between the distance measurement between the clamping plates and the distance measurement between the measurement plates. Users can easily obtain the required measurement data, reducing the cumbersome operations common in traditional measurement tools and greatly improving the work efficiency;

[0063] (4) The present invention utilizes a setting method in which a screw rod, a support plate, a support frame, and universal wheels cooperate with each other, so that the moving frame can be reversed, which is convenient for positioning and installing the elevator landing door. At the same time, it can also act as a material conveying device on the construction site, serving two purposes in one, being applicable to various construction sites and meeting the diverse needs of users.

Detailed implementation manners

[0075] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0076] The present invention provides an elevator landing door positioning device as Figures 1-10 shown, which includes a moving frame 1, a support mechanism 2, an adjustment mechanism 3, a dotting and measuring mechanism 4, and a measuring plate 5. The support mechanism 2 is arranged on the moving frame 1 and is used to adjust the position of the moving frame 1. The adjustment mechanism 3 is arranged on the moving frame 1. The dotting and measuring mechanism 4 is movably arranged on the moving frame 1 through the adjustment mechanism 3 and is used for punctuating, clamping, and measuring distances. The measuring plate 5 is arranged on the dotting and measuring mechanism 4. The measuring plate 5 is located at the edge of the fixing plate 461, which is convenient for measuring some smaller distances and the distances required to be measured after the elevator is completed, so as to observe whether they meet the requirements.

[0077] Specifically, the support mechanism 2 includes a screw rod 21, a support plate 22, a support frame 23, and universal wheels 24. Adjustment grooves are equidistantly opened at the bottom end of the moving frame 1. One end of the screw rod 21 is threadedly inserted into the inner cavity of the adjustment groove. The support plate 22 is fixedly connected to the bottom end of the screw rod 21. The positions of the support plates 22 can be finely adjusted through the screw rod 21. Cooperating with a plurality of spirit levels 7, the entire moving frame 1 can be in a horizontal state during use, which is convenient for drilling position dotting and positioning installation operations. The support frames 23 are symmetrically and fixedly connected to the top end of the moving frame 1. The universal wheels 24 are symmetrically and rotatably installed inside the support frames 23. By flipping the moving frame 1, at this time, the universal wheels 24 contact the ground, and the entire device can be used as a transportation device to bundle and transport some materials, serving two purposes in one, which is convenient for use.

[0078] Specifically, the adjustment mechanism 3 includes a motor 31, a driving 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 mobile frame 1. The motor 31 is electrically connected to the external power supply through an external switch. The end of the driving rod 32 is rotatably connected with the inner wall of the mobile frame 1. The output end of the motor 31 is transmission-connected with one end of the driving rod 32. The slider 33 and the driving rod 32 form a screw transmission. The driving rod 32 is driven by the motor 31 to rotate in the forward and reverse directions, so that the slider 33 can be The movable frame 1 is displaced inside, thereby driving the adjusting frame 34 to move back and forth in the vertical direction. The adjusting frame 34 is fixedly connected to the outer wall of the slider 33, and the end of the first bidirectional screw 35 is rotatably and interlacedly connected with the inner wall of the adjusting frame 34. The dot-marking measuring mechanism 4 is displaced by the first bidirectional screw 35, and then the dot-marking measuring mechanism 4 inside the adjusting frame 34 is moved closer to or farther away from each other by the rotation of the first bidirectional screw 35, so that operations such as drilling and dot-marking at different distances or distance measurement can be performed as needed.

[0079] Specifically, the dot 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 rotation measuring assembly 46. The sleeve 41 is symmetrically arranged inside the adjustment frame 34. The sleeve 41 and the first bidirectional screw 35 form a screw transmission. One end of the fixed rod 42 is slidably connected with the inner cavity of the sleeve 41, and the other end of the fixed rod 42 is slidably connected with the inner cavity of the displacement rod 43. One end of the displacement rod 43 is slidably connected with 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 is provided with 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, the other end of the first compression spring 45 is fixedly connected to the displacement rod 43, and the rotation measuring component 46 is arranged at the other end of the displacement rod 43. The first compression spring 45 is always in a compressed state, thereby providing 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, which is convenient for pulling the displacement rod 43 by the first pull rod 44 during the drilling and spotting operation, and after the spotting is completed, it can also be restored under the elastic force of the first compression spring 45, which is convenient for use.

[0080] Further, the rotation measurement assembly 46 includes a fixed plate 461, a rotating plate 462, a clamping and dotting assembly 463, a positioning assembly 464, and a measurement assembly 465. The fixed plate 461 is arranged at the other end of the displacement rod 43. One end of the rotating plate 462 is fixedly connected to the fixed plate 461. A rotating groove is formed at the other end of the displacement rod 43. The rotating plate 462 is rotationally inserted into the inner cavity of the rotating groove through a rotating shaft. The clamping and dotting assembly 463 is arranged inside the fixed plate 461 and is used for clamping elevator parts. The positioning assembly 464 is arranged at the other end of the displacement rod 43 and is used for multi-point positioning of the rotating plate 462. The measurement assembly 465 is arranged inside the fixed plate 461 and is used for measuring the dotting distance and the distance between the measuring plates 5. By using the positioning assembly 464 to fix the clamping and dotting assembly 463 in different states, when the fixed plate 461 and the displacement rod 43 are on the same horizontal line, the clamping and dotting assembly 463 can clamp the sill track to be installed and other components. And during clamping, the clamping distance can be determined by the measurement assembly 465, which is convenient for installation. When the fixed plate 461 and the displacement rod 43 are in a perpendicular state, the clamping and dotting assembly 463 can complete synchronous dotting at the position to be dotted under the pulling of the first pull rod 44, and the dotting distance can also be measured by the measurement assembly 465. The design of the rotating plate 462 enables the clamping and dotting assembly 463 to flexibly adjust the angle to adapt to different installation environments and requirements, so that the device can not only be used for installation on a horizontal plane, but also effectively dot on an inclined plane or a vertical plane, further expanding its application range. The high-precision sensor of the measurement assembly 465 can real-time feedback the clamping distance and the dotting position, ensuring that users can quickly obtain the required data and reducing the errors that may be caused by manual measurement in the traditional method. This design greatly improves the work efficiency and reduces the repeated adjustment and inspection during the installation process.

[0081] Further, the clamping and dotting assembly 463 includes a second bidirectional screw 4631, clamping plates 4632, limit blocks 4633, anti-slip pads 4634, marking pens 4635 and protective covers 4636. A groove is formed at the bottom end of the fixed 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 arranged inside the groove. The clamping plate 4632 and the second bidirectional screw 4631 form a lead screw drive. By rotating the second bidirectional screw 4631, the clamping plates 4632 can be moved closer to or away from each other, so as to clamp the elevator sill track, facilitating subsequent installation. Other components can also be clamped for convenient installation. Limit slots are formed on both sides of the inner wall of the groove. The limit blocks 4633 are slidably inserted into the inner cavity of the limit slots. The limit blocks 4633 are fixedly connected to the clamping plates 4632. The limit blocks 4633 play a role in limiting the clamping plates 4632, so that the clamping plates 4632 can only reciprocate along the direction of the limit slots under the rotation of the second bidirectional screw 4631. The anti-slip pads 4634 are embedded at the bottom of the clamping plates 4632 and are used to contact elevator car door parts. The anti-slip pads 4634 are provided to increase the friction between the clamping plates 4632 and the clamped parts, making the clamping effect better. An installation groove is formed at the bottom end of the clamping plate 4632. The marking pen 4635 is threadedly inserted into the inner cavity of the installation groove. The protective cover 4636 is threadedly inserted into the bottom of the clamping plate 4632 and is used to isolate the marking pen 4635. By opening the protective cover 4636, the marking pen 4635 can be exposed, so that the clamping plate 4632 has the function of dotting under the pulling of the first pull rod 44, which is convenient for use.

[0082] Further, the positioning component 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 rotation 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 rotation plate 462. The other end of the positioning rod 4641 is matched 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 arranged 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, so as to provide a stable elastic force to the positioning rod 4641, so that the positioning rod 4641 always extends out and fits against the bottom end of the rotation plate 462, and the rotation plate 462 can be limited, so that the fixed plate 461 can be maintained on the same horizontal line as the displacement rod 43. When the state of the fixed plate 461 needs to be adjusted, the positioning rod 4641 can be pulled through the second pull rod 4642, so that the fixed plate 461 can be turned to a vertical state, so that the positioning rod 4641 can be engaged with the positioning hole, which is convenient for fixing the fixed plate 461 in a vertical state and facilitating the drilling and dotting operation of the sill track installation frame on the inner wall of the elevator shaft.

[0083] Further, the measuring component 465 includes a laser distance measuring transmitter 4651, a laser distance measuring receiver 4652, a linkage plate 4653, a telescopic rod 4654, a third compression spring 4655, a pressing plate 4656, a pressing rod 4657, a sliding block 4658 and a rotating frame 4659. The laser distance measuring transmitter 4651 is rotatably connected to the top end of one of the clamping plates 4632 through a rotating shaft, and the laser distance measuring receiver 4652 is rotatably connected to the top end of the other clamping plate 4632 through a rotating shaft. The number of the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 is two, and the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 are staggeredly arranged at the points of the four corners from a top view angle. Thus, under the measurement of the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652, the required measurement data can be calculated and fed back to the display screen 6. Under the extrusion of the linkage plate 4653, the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 can be flipped by 90°, so as to realize the mutual conversion between the distance measurement between the clamping plates 4632 and the distance measurement between the measurement plates 5. The user can easily obtain the required measurement data, reducing the cumbersome operations common in traditional measuring tools and greatly improving the work efficiency. The bottom ends of the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 are both fixedly connected with limiting rods 8. The top ends of the clamping plates 4632 are both provided with arc-shaped grooves for the limiting rods 8 to slide. The angle of the arc-shaped groove is a quarter of a circle, which is convenient for limiting the rotation of the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652. The top end of the inner wall of the groove is provided with a displacement groove. The linkage plate 4653 is arranged inside the displacement groove. One end of the telescopic rod 4654 is fixedly connected with the inner wall of the displacement groove at equal intervals, and the other end of the telescopic rod 4654 is fixedly connected with the linkage plate 4653 at equal intervals. The third compression spring 4655 is sleeved outside the telescopic rod 4654. One end of the third compression spring is fixedly connected with the linkage plate 4653, and the other end of the third compression spring 4655 is fixedly connected with the inner wall of the displacement groove. One side of the inner wall of the displacement groove is provided with a through groove communicated with the positioning hole. The pressing plate 4656 is slidably inserted into the inner cavity of the through groove. One end of the pressing plate 4656 is provided with an inclined surface, and the pressing plate 4656 is provided with a pressing groove. One end of the pressing rod 4657 is fixedly connected with the linkage plate 4653, and the other end of the pressing rod 4657 is slidably inserted into the inner cavity of the pressing groove. The bottom end of the linkage plate 4653 is provided with a sliding groove. The 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 respectively rotatably connected with the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652, and the other end of the rotating frame 4659 is rotatably connected with the sliding block 4658. The third compression spring 4655 is always in a compressed state, so that the linkage plate 4653 can be close to the direction of the measurement plate 5. At this time, the rotating frame 4659 is in Figure 6The state shown, at this time, the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 inside the same fixing plate 461 are in a non-matching state, but are in a matching state with those inside another fixing 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 clamping plate 4632 and the edge of the fixing plate 461 can be subtracted, which is the distance between the measuring plates 5. When pre-positioning the drilling positioning, half of the thickness of the clamping plate 4632 can be added to the measurement result, which is the distance required for drilling. Such addition and subtraction operations can be implemented in the control system inside the display screen 6. When the fixing plate 461 and the displacement rod 43 are in a vertical state, the positioning rod 4641 can squeeze the extrusion plate 4656, so that the displacement can be carried out through the extrusion rod 4657, enabling the linkage plate 4653 to pull the rotating frame 4659, and making the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 in the state as Figure 7 shown, at this time, the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 inside the same fixing plate 461 are in a communicating state, so that the distance of the center position of the clamping plate 4632 can be measured, which is convenient for measuring the drilling marking distance and displaying it on the display screen 6.

[0084] Furthermore, a display screen 6 is fixedly installed on the outer wall of the moving frame 1 for displaying measurement data, and level gauges 7 are symmetrically and fixedly installed at the top of the moving frame 1.

[0085] The working principle of the present invention:

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

[0087] After adjusting the levelness, the driving rod 32 can be rotated by the motor 31, and the slider 33 can drive the adjusting frame 34 to be displaced to a suitable height. Then, by rotating the first bidirectional screw 35, multiple sleeves 41 can drive the fixing plate 461 on the displacement rod 43 to be displaced. At this time, the fixing plate 461 and the displacement rod 43 are on the same horizontal line, and the display screen 6 shows that the measured distance is exactly the distance between the two clamping plates 4632. By adding half of the thickness of the clamping plate 4632, the drilling marking position of the sill mounting bracket can be pre-marked.

[0088] Then, by pulling the second pull rod 4642, the positioning rod 4641 is received inside the positioning groove. At this time, the fixing plate 461 can be flipped by the rotating plate 462 to be perpendicular to the displacement rod 43. Then, the second pull rod 4642 is released, so that the positioning rod 4641 can be inserted into the positioning hole. Thus, while fixing the fixing plate 461 in a vertical state, the pressing plate 4656 can be pressed. The displacement of the pressing rod 4657 inside the pressing groove causes the linkage plate 4653 to pull the rotating frame 4659, and the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 to rotate. At this time, the laser distance measuring transmitter 4651 and the laser distance measuring receiver 4652 inside the same fixing plate 461 are in a communicating state, so that the distance from the center position of the clamping plate 4632 can be measured, facilitating the adjustment of the drilling and marking distance, and the value is measured and displayed on the display screen 6. At this time, the protective cover 4636 can be unscrewed to expose the marker pen 4635. Thus, under the pull of the first pull rod 44, the marker pen 4635 can mark the inner wall of the elevator shaft. After the installation of the landing sill track mounting bracket is completed by drilling, the landing sill track can be clamped by the clamping plate 4632 to complete the installation of the elevator landing sill track.
