Description
Technical Field

[0002] Elevator guide rails are vital components in the elevator system. They are mainly composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. The cross-sectional shapes include T-shaped, L-shaped and hollow. The guide rails not only provide precise guidance for the elevator car and counterweight, but also withstand various impact forces during elevator operation, such as the impact force during braking and emergency braking of the safety clamp. The magnitude of these forces is closely related to the load capacity and speed of the elevator. Therefore, choosing suitable guide rails is crucial to ensuring the safe operation of the elevator. The guide rails have strong rigidity and high reliability, and must be smooth during installation without obvious uneven surfaces to ensure the smooth operation of the elevator and the comfort of passengers. With the continuous development of elevator technology, high-precision guide rails have gradually become a market trend to meet the higher requirements of high-speed elevators for guide rail accuracy and stability.
[0003] Elevator guide rails are important components used in elevator operation. Existing guide rails are mostly inspected by cameras, which perform inspections through image analysis and comparison. Some minor changes may cause the camera to be unable to distinguish, resulting in the danger not being eliminated in time, and increasing the risk of elevator operation.
[0004] Therefore, it is necessary to redesign the guide rail detection device to effectively prevent the existing guide rails from being detected mostly by camera devices, and detecting through image analysis and comparison. For some minor changes, the camera device may not be able to distinguish them, resulting in the danger cannot be eliminated in time, resulting in increased danger of elevator operation.

Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0037] like Figures 1 to 4 As shown, the utility model provides a high-precision elevator guide rail 2 detection device, comprising:
[0038] Fixed plate 1;
[0039] Guide rails 2 are fixedly mounted on both sides of the bottom of the fixed plate 1 and are used to limit the position of the elevator;
[0040] The moving mechanism 3 is installed on the top of the fixed plate 1 and is used to detect the movement of the guide rail 2;
[0041] The detection mechanism 4 is installed on the surface of the guide rail 2 and is used to perform efficient detection on the guide rail 2.
[0042] like Figures 1 to 4As shown, the moving mechanism 3 includes a motor 301, which is fixedly mounted on the top of the fixed plate 1, and a worm 302 is fixedly connected to the output end of the motor 301. A worm wheel 303 is meshed on the surface of the worm 302. The end of the worm 302 away from the motor 301 is movably connected to a support plate 304 through a bearing seat. The bottom of the support plate 304 is fixedly connected to the top of the fixed plate 1, and the inside of the worm wheel 303 is fixedly connected to a cross bar 305. Both ends of the cross bar 305 are movably connected to a stabilizing plate 306 through a bearing seat. The bottom of the stabilizing plate 306 is movably connected to the The top of the fixed plate 1 is fixedly connected, and both sides of the surface of the cross bar 305 are fixedly connected with a winding wheel 307, and the surface of the winding wheel 307 is fixedly connected with a winding rope 308. The inner side of the guide rail 2 is movably connected with a bidirectional screw 309 through a bearing seat, and both sides of the surface of the bidirectional screw 309 are threadedly connected with a screw sleeve 311. The internal sliding connection of the screw sleeve 311 is connected to a limit rod 312, and both ends of the limit rod 312 are fixedly connected to the guide rail 2. The front of the screw sleeve 311 is fixedly connected with a guide ring 313, and the winding rope 308 passes through the interior of the guide ring 313.
[0043] In the embodiment of the present invention (working principle), when in use, the user drives the motor 301 and the worm gear 303 and the worm 302.
[0044] Driven by motor 301: Motor 301 is fixedly mounted on the top of fixed plate 1 and serves as the power source of the entire detection device. When motor 301 is started, its output end drives worm 302 to rotate.
[0045] The worm gear 303 and worm 302 are driven by the worm gear 302: The surface of the worm gear 302 meshes with the worm gear 303, so rotation of the worm gear 302 drives the worm gear 303 to rotate synchronously. The worm gear 303 and worm 302 transmission has a large transmission ratio and self-locking properties, ensuring stable and reliable transmission. The end of the worm gear 302 away from the motor 301 is flexibly connected to the support plate 304 via a bearing seat. The support plate 304 is fixedly mounted on the fixed plate 1, providing stable support for the worm gear 303.
[0046] Retraction and Extension of Retraction Rope 308
[0047] Crossbar 305 and Reel 307: Crossbar 305 is fixedly connected to the interior of worm gear 303 and rotates with it. Both ends of crossbar 305 are movably connected to stabilizing plate 306 via bearing blocks. Stabilizing plate 306 is fixedly mounted on fixed plate 1, providing support for crossbar 305. Reel 307 is fixedly connected to both sides of crossbar 305, rotating with crossbar 305.
[0048] Winding rope 308: A winding rope 308 is fixedly attached to the surface of the winding wheel 307. As the winding wheel 307 rotates, the winding rope 308 is wound or released, thereby moving the portion of the detection device connected to the winding rope 308 along the elevator guide rail 2. This design allows the detection device to move flexibly on the guide rail 2, enabling precise detection.
[0049] Adjustment of the bidirectional screw 309 and the screw sleeve 311
[0050] Bidirectional screw 309: The inner side of the guide rail 2 is movably connected to a bidirectional screw 309 through a bearing seat, and the right side of the bidirectional screw 309 is fixedly connected to a motor 310. When the motor 310 is started, the bidirectional screw 309 is driven to rotate.
[0051] Sleeve 311 and Limiting Rod 312: Sleeves 311 are threadedly connected to both sides of the bidirectional screw 309. The interior of the sleeve 311 is designed with threads that match the threads of the bidirectional screw 309. Therefore, when the bidirectional screw 309 rotates, the sleeve 311 will reciprocate along the screw. The interior of the sleeve 311 is slidably connected to the limiting rod 312. The ends of the limiting rod 312 are fixedly connected to the guide rail 2, ensuring that the sleeve 311 will not rotate during movement and can only slide along the limiting rod 312 to meet the requirements of high-precision detection.
[0052] Guiding function of guide ring 313
[0053] Guide ring 313: The front of the screw sleeve 311 is fixedly connected with a guide ring 313, and the winding rope 308 passes through the inside of the guide ring 313. The function of the guide ring 313 is to ensure that the winding rope 308 maintains a stable path during the movement.
[0054] Synergistic effect: When the winding wheel 307 rotates to reel in or release the winding rope 308, the winding rope 308 can smoothly drive the detection device part to move along the guide rail 2 through the guidance of the guide ring 313, and cooperate with the adjustment mechanism of the bidirectional screw 309 to achieve precise movement and positioning of the detection device on the guide rail 2.
[0055] like Figures 1 to 4 As shown, the detection mechanism 4 includes a fixed frame 41, and a roller 46 used in conjunction with the guide rail 2 is fixedly installed on the inner side of the fixed frame 41. The number of rollers 46 is several, and a connecting block 42 is fixedly connected to the inner side of the fixed frame 41. A control board 43 is fixedly connected to the inner side of the connecting block 42. The bottom of the winding rope 308 is fixedly connected to the top of the control board 43. A laser emitter 44 is fixedly installed on the front of the control board 43 on the left side of the motor 301. There are two laser emitters 44 in both horizontal and vertical directions. A receiver 45 used in conjunction with the laser emitter 44 is fixedly installed on the front of the control board 43 on the right side of the motor 301.
[0056] In the embodiment of the present utility model, the cooperation between the roller 46 and the guide rail 2
[0057] Roller 46 Design: Detection mechanism 4 includes a fixed frame 41, on the inside of which are fixedly mounted several rollers 46. These rollers 46 tightly mate with the sides of the elevator guide rails 2, ensuring smooth movement of detection mechanism 4 along the guide rails 2. The number and distribution of rollers 46 are carefully designed to provide sufficient support and stability while reducing friction and resistance during movement.
[0058] Movement mechanism: When the movement mechanism 3 is working, the retraction and extension of the winding rope 308 drives the fixed frame 41 and the roller 46 thereon to move along the guide rail 2. The contact surface between the roller 46 and the guide rail 2 is smooth and wear-resistant, which helps to achieve high-precision position control and detection.
[0059] Control board 43 and connection block 42
[0060] Connecting blocks 42: Connecting blocks 42 are fixedly connected to the inner side of the fixing frame 41. These connecting blocks 42 serve as a supporting structure to firmly fix the control board 43 to the detection mechanism 4. The design of the connecting blocks 42 takes into account stability and load-bearing capacity to ensure that the control board 43 will not loosen or be damaged during the detection process.
[0061] Control board 43: A core component of the testing device, it integrates various electronic components and sensors for controlling the testing process, processing test data, and communicating with other systems. Control board 43 is connected to mounting bracket 41 via connector block 42, ensuring stability and reliability during testing.
[0062] Lasers are emitted in the horizontal and vertical directions by the laser transmitter 44 and received by the receiver 45. If all are received, the horizontal and vertical directions are normal. When a receiver 45 does not receive a signal, it means that the guide rail 2 is deformed at a certain place, thereby improving the efficiency of detection.
[0063] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
