Description

Technical Field

[0001] This utility model relates to the field of elevator measuring devices, specifically a device for measuring the distance between the elevator car sill and the landing door lock roller. Background Technology

[0002] An elevator is a transportation device that serves a rigid track within a building, specifically serving a number of floors. Vertical elevators are fixed lifting devices that serve designated floors. They have a car that runs between at least two vertical or inclined rigid guide rails with an angle of less than 15°. The size and structure of the car facilitate passenger entry and exit or loading and unloading of goods.

[0003] In the elevator operation safety system, the accuracy of the distance between the car sill and the landing door lock rollers is directly related to the safety of passengers and the stability of the equipment. If the distance exceeds the standard range (usually 3-8mm), it is very easy to cause safety accidents such as jamming and trapping people or equipment failure. During the early installation and later maintenance of elevators, it is often necessary to measure the distance between the car sill and the landing door lock rollers.

[0004] However, traditional measurement methods usually use manual tools such as feeler gauges, which have problems such as low measurement efficiency, large data deviation, and manual operation is easily restricted by the shaft. In order to ensure the safe operation of elevators, a device for measuring the distance between the elevator car sill and the landing door lock roller is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a device for measuring the distance between the elevator car sill and the landing door lock roller, in order to solve the technical problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for measuring the distance between the elevator car sill and the landing door lock roller, comprising a device body, wherein the device body includes a fixing mechanism, and the device body is fixedly connected to the top of the car through the fixing mechanism;

[0007] A scale is fixedly installed on one side of the fixed mechanism, and a telescopic tube is slidably connected to the outer wall of the scale. A laser emitter is fixedly installed at the end of the telescopic tube for aligning the elevator car sill with the landing door lock roller. A sliding frame is slidably installed on the scale for use as an initial reference for measurement. A transmission mechanism is rotatably installed inside the scale, and a motor is installed inside the fixed mechanism to drive the transmission mechanism.

[0008] By adopting the above technical solution, the laser beam is precisely positioned by moving the telescopic tube. The laser beam is vertically aligned with the car sill and the landing door lock rollers. The laser beam is clearly visible in the elevator shaft, which greatly shortens the positioning time. The device utilizes the precision of mechanical transmission and the intuitiveness of laser positioning, effectively improving measurement efficiency and data accuracy, and meeting the high precision requirements of elevator safety inspection.

[0009] Furthermore, the fixing mechanism includes a motor, a level, and a magnetic block. The magnetic block is located on the side of the fixing mechanism, and the fixing mechanism is fixedly attached to the metal surface of the car top by the magnetic block. The motor and the level are fixedly installed on one side of the magnetic block.

[0010] By adopting the above technical solution, the level can be integrated into the fixed mechanism, thereby adjusting the horizontal state of the device, ensuring the reference accuracy of the laser emitter, and avoiding errors caused by device tilt during the measurement process.

[0011] Furthermore, the transmission mechanism includes a lead screw and a threaded tube, wherein the lead screw is rotatably installed at one end inside the scale, and the threaded tube is fixedly installed at one end inside the telescopic tube, and the lead screw and the threaded tube are connected by threaded engagement. The motor is electrically connected to the transmission mechanism and is used to drive the transmission mechanism to drive the telescopic tube to perform telescopic movement.

[0012] By adopting the above technical solution, the screw and threaded tube are driven by a motor to perform threaded transmission, which converts the rotational motion of the screw into the axial linear motion of the threaded tube, thereby smoothly pushing the telescopic tube.

[0013] Furthermore, the plane at the end of the sliding frame protrudes beyond the plane at the end of the fixing mechanism, allowing the operator to move the sliding frame.

[0014] By adopting the above technical solution, the position of the sliding frame is used as an initial reference, and it is synchronously referenced with the last mark of the telescopic tube on the scale to achieve fast and accurate measurement.

[0015] In summary, the present invention has the following main advantages:

[0016] This invention utilizes a motor-driven lead screw and threaded tube for threaded transmission, converting the rotational motion of the lead screw into the axial linear motion of the threaded tube. This smoothly propels the telescopic tube, and the movement of the telescopic tube enables precise positioning of the laser beam. The laser beam is vertically aligned with the car sill and landing door lock rollers. The laser beam is clearly visible within the elevator shaft, significantly reducing positioning time. Combined with the initial reference of the sliding frame and the scale reference of the ruler, rapid and accurate measurement is achieved. The device leverages the precision of mechanical transmission and the intuitiveness of laser positioning, effectively improving measurement efficiency and data accuracy, meeting the high-precision requirements of elevator safety inspection. Integrating a level into the fixed mechanism allows for adjustment of the device's horizontal state, ensuring the reference accuracy of the laser emitter and preventing errors caused by device tilt during measurement.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] Example 1

[0025] A device for measuring the distance between the elevator car sill and the landing door lock roller, such as... Figure 1-4 As shown, the device includes a main body 1, which includes a fixing mechanism 10, and the main body 1 is fixedly connected to the top of the car through the fixing mechanism 10.

[0026] A scale 12 is fixedly installed on one side of the fixed mechanism 10, and a telescopic tube 13 is slidably connected to the outer wall of the scale 12. A laser emitter 14 is fixedly installed at the end of the telescopic tube 13 for aligning the elevator car sill and the landing door lock roller. The laser beam is precisely positioned by moving the telescopic tube 13. The laser beam is vertically aligned with the car sill and the landing door lock roller. The laser beam is clearly visible in the elevator shaft, which greatly shortens the positioning time. A sliding frame 11 is slidably installed on the scale 12 for use as the initial reference for measurement. A transmission mechanism is rotatably installed inside the scale 12, and a motor 101 is installed inside the fixed mechanism 10 to drive the transmission mechanism. By utilizing the precision of mechanical transmission and the intuitiveness of laser positioning, the measurement efficiency and data accuracy are effectively improved, meeting the high precision requirements of elevator safety inspection.

[0027] Please see Figure 1-4 The fixing mechanism 10 includes a motor 101, a level 102, and a magnetic block 103. The magnetic block 103 is located on the side of the fixing mechanism 10, and the fixing mechanism 10 is fixedly attached to the metal surface of the car top by the magnetic block 103. The motor 101 and the level 102 are fixedly installed on one side of the magnetic block 103. The level 102 is integrated into the fixing mechanism 10, which can adjust the horizontal state of the device, thereby ensuring the reference accuracy of the laser emitter 14 and avoiding errors caused by the tilt of the device during the measurement process.

[0028] Please see Figure 1-4 The transmission mechanism includes a lead screw 121 and a threaded tube 131. The lead screw 121 is rotatably mounted at one end inside the scale 12, and the threaded tube 131 is fixedly mounted at one end inside the telescopic tube 13. The lead screw 121 and the threaded tube 131 are connected by a threaded engagement. The motor 101 is electrically connected to the transmission mechanism and is used to drive the transmission mechanism to move the telescopic tube 13 in telescopic motion. By driving the lead screw 121 and the threaded tube 131 through threaded transmission by the motor 101, the rotational motion of the lead screw 121 is converted into the axial linear motion of the threaded tube 131, thereby smoothly pushing the telescopic tube 13.

[0029] Please see Figure 1-4 The plane at the end of the sliding frame 11 protrudes beyond the plane at the end of the fixing mechanism 10, allowing the operator to move the sliding frame 11. The position of the sliding frame 11 is used as an initial reference, and it is synchronized with the last mark on the scale 12 of the telescopic tube 13 to achieve fast and accurate measurement.

[0030] The working principle of this utility model is as follows: When the staff is performing measurement work, the fixing mechanism 10 of the main body 1 of the device is attached to the metal surface of the side wall of the car top by magnetic block 103, and the level 102 is observed to ensure that the main body 1 of the device is in a horizontal state, thereby ensuring the accuracy of the measurement benchmark and avoiding measurement deviation caused by the tilt of the main body 1 of the device.

[0031] After completing the preparations, turn on the laser emitter 14 to emit a laser beam. The motor 101 drives the lead screw 121 to rotate synchronously. The threads on the surface of the lead screw 121 and the threads inside the threaded tube 131 mesh with each other, converting the rotational motion of the lead screw 121 into the axial linear motion of the threaded tube 131. This causes the threaded tube 131 to move outward along the lead screw 121, thereby pushing the telescopic tube 13 to move outward smoothly. When the laser beam is vertically aligned with the car sill, immediately stop the operation of the motor 101 and slide the sliding frame 11 along the scale 12 to the side of the telescopic tube 13 to make the sliding frame 11 the initial reference object.

[0032] Subsequently, the motor 101 is restarted and operated. The lead screw 121 and the threaded tube 131 work together to move the laser beam outward to the position and align it with the landing door lock roller. The motor 101 is then stopped immediately. By observing the distance between the sliding frame 11 and the telescopic tube 13 on the scale 12, the distance between the car sill and the landing door lock roller can be determined. The main body 1 of this device utilizes the precision of mechanical transmission and the intuitiveness of laser positioning to effectively improve measurement efficiency and data accuracy, meeting the high precision requirements of elevator safety inspection.

[0033] After the measurement is completed, simply drive the lead screw 121 to rotate via the motor 101. During the process of the lead screw 121 driving the telescopic tube 13 to reset, the telescopic tube 13 contacts the slide frame 11 and pushes it to reset. After the telescopic tube 13 and the slide frame 11 have completed their reset, manually release the magnetic block 103 and store the main body 1 of the device.
