Description

Technical Field

[0001] This invention relates to the field of sliding door technology, specifically to an adaptive compensation double sliding door and its adjustment method. Background Technology

[0002] Sliding doors, due to their combination of lateral sliding and inward / outward sliding characteristics, are widely used in rail transit cars, special enclosed cabins, and large equipment passages. Among them, the double-opening structure has become the mainstream configuration due to its high opening and closing efficiency and large passage space. Most existing double-opening sliding doors use synchronous belt drives combined with single or double-sided drives to achieve door opening and closing, and rely on simple mechanical limits to complete position control. However, the following technical defects have gradually been exposed during long-term high-frequency operation.

[0003] 1. Traditional transmission systems do not have a tension adaptive compensation mechanism. After long-term stretching and wear, the synchronous belt is prone to problems such as tension reduction and transmission clearance increase, which in turn causes cumulative positional deviation of the door opening and closing, resulting in misalignment of the double door closing and reduced airtightness, which cannot meet the sealing requirements. Moreover, abnormal tension can only be corrected manually on a regular basis, which is cumbersome to maintain, has a slow response, and is difficult to adapt to continuous operation scenarios. 2. In addition, traditional door panels and synchronous belts are mostly rigidly fixed connections. When positional deviations occur, it is impossible to achieve decoupled fine-tuning of a single door. The entire transmission mechanism needs to be disassembled, resulting in low debugging efficiency and complex operation. Furthermore, the lack of real-time door displacement monitoring and closed-loop control makes it impossible to accurately identify deviations and automatically correct them. This makes it difficult to meet the requirements of high-precision and high-reliability opening and closing, thus restricting the application of double-leaf sliding doors in the field of high-end airtight equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adaptive compensation double-leaf sliding door and its adjustment method. The main purpose is to solve the problems of the inability to achieve decoupled fine-tuning of a single door when the door body has positional deviations, the need to disassemble the transmission mechanism as a whole, low debugging efficiency, and complex operation.

[0009] As a further embodiment of the present invention, the fastening component is a pressure plate, and a rubber pad is detachably installed on the bottom of the pressure plate, with deformation grooves formed on the lower surface of the rubber pad.

[0010] As a further embodiment of the present invention, the traction system includes an assembly box fixedly connected to one side of the crossbeam. A connecting shaft is rotatably mounted in the assembly box via a bearing. A self-compensating gear is fixedly connected to the outer circumference of the connecting shaft. A self-compensating rod passes through the assembly box. The bottom of the self-compensating rod has a toothed groove that mates with the self-compensating gear. A tension sensor is fixedly connected to one end of the self-compensating rod. A pull rod is fixedly connected to one end of the tension sensor, and the end of the pull rod is fixed to the self-compensating slide.

[0011] As a further embodiment of the present invention, the monitoring system includes a matching distance sensor and a sensing element, wherein the distance sensor is fixedly connected to the bottom of the crossbeam and the sensing element is fixedly connected to one side of the pulley block.

[0012] As a further embodiment of the present invention, the locking assembly includes a positioning cylinder and a pin seat that cooperate with each other. The positioning cylinder is fixedly connected inside the crossbeam, and the pin seat is fixedly connected to one side of the pulley block.

Two slotted photoelectric switches that cooperate with the sensor frame are fixedly connected to one side of the side mounting plate.

[0014] An adaptive compensation adjustment method for a double-opening sliding door includes the following steps: S1: The tension sensor monitors the tension transmitted to the tie rod by the self-compensating rod in real time. When the tension is abnormal, such as too large or too small, the tension sensor will feed back the signal to the control system. The control system will adjust the self-locking geared motor according to the feedback signal to ensure that the tension detected by the tension sensor is within the specified range, thus completing the adaptive compensation of the synchronous belt tension. S2: The monitoring system monitors the position information of the first and second sliding doors of the double-leaf sliding door in real time, accurately determines whether the current position of the first and second sliding doors meets the preset position requirements, and adjusts the opening and closing position when the position of the first and second sliding doors deviates. S3: First, taking the position of the second sliding door as a reference, the distance sensor of the monitoring system accurately detects the position information of the second sliding door. Then, the drive motor drives the second sliding door to move to the closed position. Finally, the locking component locks the position of the second sliding door. S4: Then disconnect the plug door 2 from the synchronous belt, that is, open the closing mechanism; S5: At this time, the distance sensor of the monitoring system accurately detects the position information of the sliding door one, and then the drive motor drives the sliding door one to move to the closed position. Then, the locking component locks the position of the sliding door one. S6: Then restore the connection between the second sliding door and the synchronous belt, that is, close the closing mechanism; S7: At this point, the position of the first and second sliding doors of the double-opening sliding door is quickly corrected.

[0015] Compared with existing technologies, this invention provides an adaptive compensation double-opening sliding door and its adjustment method, which has the following beneficial effects: This invention is equipped with an adaptive compensation drive system and a tension sensor, combined with a worm gear and a self-locking geared motor with a two-stage self-locking structure, to monitor and compensate for the tension of the synchronous belt in real time, automatically eliminating the cumulative error caused by long-term operation; and through the monitoring system, the displacement data of sliding door one and sliding door two are collected in real time and fed back to the control system. During the operation of the door, if the position exceeds the specified range due to mechanical fatigue or cumulative error of the adaptive compensation drive system, the system can immediately trigger the adjustment program, solving the problem of double-opening sliding door opening and closing position deviation from the root, ensuring the synchronous operation accuracy of the two doors, improving the sealing effect of the door, adapting to high-frequency operation scenarios, significantly reducing the frequency of equipment debugging, and extending the service life of core transmission components.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0021] Please see Figures 1-15 As shown, the adaptive compensation double-opening sliding door includes a crossbeam 2, a double-opening sliding door 1, an adaptive compensation drive system 3, at least two sets of monitoring systems 6, at least two sets of locking components 7, and two sets of sliding components 4. A horizontal guide rail 201 is installed at the bottom of the crossbeam 2; the double-opening sliding door 1 includes a sliding door 101 and a sliding door 202, both of which are installed on the horizontal guide rail 201 by two sets of pulleys 5. Pulley block 5 includes a pulley frame, inside which are installed two upper pulleys and a middle anti-lateral deflection wheel. The two upper pulleys and the middle anti-lateral deflection wheel are distributed above and in the middle of the transverse guide rail 201, respectively. The middle anti-lateral deflection wheel is engaged inside the transverse guide rail 201 (e.g., Figure 14 As shown), this allows the pulley block 5 to move stably on the transverse guide rail 201; like Figure 13 As shown, two sets of sliding door components 4 are located at both ends of the crossbeam 2, respectively, and are used to drive the crossbeam 2 and the double-opening sliding door 1 to perform sliding action. The sliding door component 4 includes a side mounting plate 401 installed in the carriage. Two sets of side mounting seats 406 are fixed to one side of the side mounting plate 401 by bolts. A side guide rail 402 is fixed inside the side mounting seat 406 by bolts. A sliding sleeve 404 is slidably installed on one side of the side guide rail 402 via a sliding table. A side connecting plate 4 is fixed between the two sliding sleeves 404 by bolts. 07, and the side connecting plate 407 is fixed to the crossbeam 2. The spool assembly 4 is equipped with a spool cylinder 409 that drives the side connecting plate 407 to move along the side guide rail 402. The inside of the side mounting base 406 is fixed with a light rod 405 by bolts, and the light rod 405 passes through the inside of the sliding sleeve 404. The top of the sliding sleeve 404 is fixed with a sensor frame 408 by bolts. Two slotted photoelectric switches 403 that cooperate with the sensor frame 408 are fixed with bolts on one side of the side mounting plate 401. Specifically, the piston rod end of the hydraulic cylinder 409 is connected to the side connecting plate 407. When the hydraulic cylinder 409 is activated, it can drive the side connecting plate 407 to slide smoothly along the side guide rail 402. The smooth rod 405 serves to guide and stabilize the movement of the sliding sleeve 404, making the sliding sleeve 404 slide more smoothly on the side guide rail 402 and reducing jamming and offset.

[0022] The slotted photoelectric switch 403, in conjunction with the sensing frame 408, can accurately detect the position of the sliding sleeve 404. When the sliding sleeve 404 moves to a specific position, the sensing frame 408 will trigger the corresponding slotted photoelectric switch 403, thereby providing feedback on the position information of the sliding sleeve 404. This information allows the control system to precisely control and adjust the sliding action.

[0023] The symmetrical arrangement of the two sets of sliding door components 4 ensures the balance and synchronization of the crossbeam 2 and the double-leaf sliding door 1 during the sliding action. When driving the double-leaf sliding door 1 to perform the sliding action, the sliding door components 4 on both sides work simultaneously, enabling the double-leaf sliding door 1 to complete the opening and closing actions smoothly and steadily, avoiding the situation where one side moves faster than the other, thus improving the operational stability and safety of the double-leaf sliding door 1.

[0024] After a long period of operation, the opening and closing positions of the double-leaf sliding door 1 will deviate to a certain extent. For example, the tension error of the synchronous belt 303 and the cumulative error after continuous adaptive adjustment of the adaptive compensation drive system 3 will all cause the opening and closing position deviation of the double-leaf sliding door 1 and affect the sealing effect of the double-leaf sliding door 1.

[0025] like Figure 9 As shown, the monitoring system 6 is installed at the bottom of the crossbeam 2 to monitor the positions of the sliding door 101 and the sliding door 2 102. The monitoring system 6 includes a matching distance sensor 601 and a sensing element 602. The distance sensor 601 is fixed to the bottom of the crossbeam 2 by bolts, and the sensing element 602 is fixed to one side of the pulley block 5 by bolts. Specifically, when the double-opening sliding door 1 is sliding, sliding door one 101 and sliding door two 102 move on the side guide rail 402 along with the pulley block 5. At this time, the distance sensor 601 monitors the distance between itself and the sensing plate 602 in real time. Since the sensing plate 602 is fixed to one side of the pulley block 5, the movement of the pulley block 5 will drive the sensing plate 602 to move synchronously. In this way, the distance change detected by the distance sensor 601 can accurately reflect the position status of sliding door one 101 and sliding door two 102.

[0026] The monitoring system 6 promptly feeds back the monitored position information of the double-leaf sliding door 1 to the control system. Based on this feedback, the control system can accurately determine whether the current position of the sliding door meets the preset position requirements. If the position of the sliding door deviates, the control system can quickly make adjustments to return sliding door 101 and sliding door 102 to the correct position, thereby ensuring the normal operation of the double-leaf sliding door 1.

[0027] like Figures 5-8 As shown, in order to solve the problem of the double-opening sliding door 1 shifting after long-term use, an adaptive compensation drive system 3 is installed on one side of the crossbeam 2 to drive the sliding door 101 and the sliding door 2 102 to perform synchronous opening and closing actions. The adaptive compensation drive system 3 includes a drive motor 301, a self-compensating carriage 305 and a traction system. The drive motor 301 is fixed to one side of the crossbeam 2 by bolts. One end of the output shaft of the drive motor 301 is fixed to the drive synchronous pulley 302 by bolts. When the drive motor 301 is started, it drives the drive synchronous pulley 302 to rotate. The self-compensating slide 305 is slidably installed between two self-compensating guide rails 304 via a slide table. Both self-compensating guide rails 304 are fixed to one side of the crossbeam 2 by bolts. A driven synchronous pulley 306 is rotatably installed on one side of the self-compensating slide 305, and the driven synchronous pulley 306 and the driving synchronous pulley 302 are connected by a synchronous belt 303. Therefore, the rotation of the driving synchronous pulley 302 drives the driven synchronous pulley 306 to rotate synchronously through the synchronous belt 303, at which time the synchronous belt 303 is displaced. like Figures 10-12 As shown, one of the pulley blocks 5 on the first sliding door 101 is fixed above the synchronous belt 303 via an upper connecting plate 501, and another pulley block 5 on the second sliding door 102 is connected below the synchronous belt 303 via a lower connecting plate 502. When the synchronous belt 303 is displaced, the cooperation of the upper connecting plate 501, the lower connecting plate 502, and the pulley blocks 5 drives the first sliding door 101 and the second sliding door 102 to open or close synchronously along the transverse guide rail 201. The lower connecting plate 502 is connected to the synchronous belt 303 via a closing mechanism. The structure includes a lower retainer 50203 bolted to one side of the lower connecting plate 502. A pressure frame 50202 is slidably mounted on one side of the lower retainer 50203. A synchronous belt 303 passes between the pressure frame 50202 and the lower retainer 50203. A dual-shaft cylinder 50201 is bolted to the other side of the lower connecting plate 502, and one end of the piston rod of the dual-shaft cylinder 50201 is fixed to the pressure frame 50202. A fastening component 50206 for locking the synchronous belt 303 is bolted to the bottom of the pressure frame 50202. The fastening component 50206 is a friction plate 50207 (e.g., ...). Figure 10 As shown), the friction plate 50207 has fine anti-slip textures. The friction plate 50207 is made of polyurethane material, which has good wear resistance and elasticity.

[0028] Specifically, when the piston rod of the dual-axis cylinder 50201 extends, the pressure frame 50202 moves upward, and the friction plate 50207 separates from the synchronous belt 303, facilitating the adjustment of the positions of the first sliding door 101 and the second sliding door 102. Moreover, the entire closing mechanism has a compact structure and is installed in a limited space, so it will not interfere with the normal operation of the double-opening sliding door 1. When the piston rod of the dual-axis cylinder 50201 retracts, it will drive the pressure frame 50202 to move downward, so that the friction plate 50207 presses tightly on the synchronous belt 303. At this time, the lower baffle 50203 and the friction plate 50207 form a pressing chamber for the synchronous belt 303. The friction plate 50207 uses the friction force generated by the fine anti-slip texture to effectively lock the synchronous belt 303, ensuring the synchronous movement between the first sliding door 101 and the second sliding door 102. Meanwhile, since the synchronous belt 303 is provided with key teeth that cooperate with the driven synchronous pulley 306 and the driving synchronous pulley 302, the synchronous belt 303 can be continuously locked and fixed by the friction plate 50207. Furthermore, the 50207 friction plate made of polyurethane material can effectively resist wear during long-term use, ensuring the stability and reliability of the locking function.

[0029] As another embodiment, such as Figure 12 As shown, the fastening component 50206 is a pressure plate 50208, and a rubber pad 50209 is detachably installed on the bottom of the pressure plate 50208. The lower surface of the rubber pad 50209 has deformation grooves.

[0030] When the piston rod of the dual-axis cylinder 50201 actuates, the pressure plate 50208 moves downward along with the pressure frame 50202. Due to its soft material properties, the rubber pad 50209 conforms better to the surface of the synchronous belt 303 upon contact, and the design of the deformation grooves further enhances this conformity. When the pressure plate 50208 presses down, the rubber pad 50209 is compressed, and the deformation grooves deform, adapting to the keyed structure on the surface of the synchronous belt 303, thus increasing the contact area between the rubber pad 50209 and the synchronous belt 303. This significantly increases the friction between the rubber pad 50209 and the synchronous belt 303, resulting in a more secure locking of the synchronous belt 303.

[0031] Moreover, the rubber pad 50209 has a certain degree of elasticity, which can effectively buffer the impact between the pressure plate 50208 and the synchronous belt 303 during long-term use, reduce damage to the synchronous belt 303, and extend the service life of the synchronous belt 303.

[0032] In addition, the rubber pad 50209 has a relatively low cost and is easy to replace. When the friction of the rubber pad 50209 decreases due to long-term wear, it can be replaced in time to maintain normal function. The rubber pad 50209 can be installed by adhesive or by locking it with screws. Regardless of the method, the rubber pad 50209 must be partially embedded in the pressure plate 50208. This ensures that the rubber pad 50209 will not fall off or shift from the pressure plate 50208 when under pressure, thus ensuring the stability and effectiveness of its contact with the synchronous belt 303.

[0033] Furthermore, in this invention, the bottom end of the pressure frame 50202 is fixed with an iron plate 50204 by bolts, and one side of the lower connecting plate 502 is fixed with an electromagnet 50205 that cooperates with the iron plate 50204 by bolts. When the electromagnet 50205 is energized, it attracts the iron plate 50204, thus locking the position of the pressure frame 50202 a second time. This magnetic connection method is not only convenient to install and disassemble, but also provides a stable and reliable connection force. During the operation of the double-opening sliding door 1, it can effectively prevent loosening or displacement between the pressure frame 50202 and the lower connecting plate 502, ensuring the stability and reliability of operation.

[0034] like Figures 5-8 As shown, the traction system of this invention is installed on one side of the crossbeam 2 for traction of the self-compensating carriage 305. The traction system includes an assembly box 310 fixed to one side of the crossbeam 2 by bolts. A connecting shaft 314 is rotatably mounted in the assembly box 310 via bearings. A self-compensating gear 315 is fixed to the outer circumference of the connecting shaft 314 by bolts. A self-compensating rod 309 passes through the assembly box 310. The bottom of the self-compensating rod 309 has a toothed groove 30901 that mates with the self-compensating gear 315. A tension sensor 308 is fixed to one end by bolts. A pull rod 307 is fixed to one end of the tension sensor 308 by bolts, and the end of the pull rod 307 is fixed to the self-compensating slide 305. A worm gear 311 is fixed to the end of the connecting shaft 314 by bolts. A worm 313 that meshes with the worm gear 311 is rotatably mounted on one side of the crossbeam 2 through a bearing seat. A self-locking geared motor 312 is fixed to one side of the crossbeam 2 by bolts, and one end of the output shaft of the self-locking geared motor 312 is fixed to the worm 313 through a coupling. Specifically, when the self-locking geared motor 312 starts, its output shaft drives the worm gear 313 to rotate. Since the worm gear 313 meshes with the worm wheel 311, the worm wheel 311 drives the connecting shaft 314 to rotate. The rotation of the connecting shaft 314 causes the self-compensating gear 315 to rotate synchronously. The self-compensating gear 315 engages with the tooth groove 30901 at the bottom of the self-compensating rod 309, driving the self-compensating rod 309 to perform linear motion. The linear motion of the self-compensating rod 309 is transmitted to the self-compensating carriage 305 through the tension sensor 308 and the pull rod 307, thus achieving traction on the self-compensating carriage 305.

[0035] The tension sensor 308 plays a crucial role throughout the process, monitoring the tension transmitted from the self-compensating rod 309 to the tie rod 307 in real time. When abnormal tension occurs, such as excessive or insufficient tension, the tension sensor 308 sends a signal back to the control system. The control system then adjusts the self-locking geared motor 312 based on the feedback signal to ensure stable operation of the traction system (see [link to relevant documentation]). Figure 15 ).

[0036] The self-locking function of the self-locking geared motor 312 is also very important. When the motor stops running, it can prevent the worm gear 313 from reversing due to external forces. Through the cooperation of the worm gear 313 and the worm wheel 311, a two-stage self-locking is achieved, thereby ensuring the positional stability of the self-compensating carriage 305. This design makes the traction system more reliable during operation and can adapt to different working environments and conditions.

[0037] In addition, the assembly box 310 provides a relatively enclosed space for components such as the connecting shaft 314 and the self-compensating gear 315, which can effectively prevent dust, debris and other contaminants from entering, protect these components from the influence of the external environment, and extend their service life.

[0038] like Figure 14 As shown, two sets of locking components 7 are used to lock the positions of sliding door 101 and sliding door 2 102. The locking components 7 include a positioning cylinder 701 and a pin seat 702 that cooperate with each other. The positioning cylinder 701 is fixed inside the crossbeam 2 by bolts, and the pin seat 702 is fixed to one side of the pulley block 5 by bolts. The piston rod is extended or retracted by opening and closing the positioning cylinder 701. When the piston rod of the positioning cylinder 701 extends, it can be inserted into the pin hole of the pin seat 702, thereby fixing the pulley block 5, thus locking the position of the first sliding door 101 and the second sliding door 102, ensuring that the double sliding door 1 remains stable in the closed state, preventing the double sliding door 1 from being accidentally opened due to external shaking or vibration, and ensuring safe use. When the double-opening sliding door 1 needs to be opened, the piston rod of the control positioning cylinder 701 retracts, causing it to be pulled out of the pin hole of the pin seat 702, thus releasing the lock on the pulley block 5. At this time, the double-opening sliding door 1 can be smoothly slid open under the action of the traction system (see [link]). Figure 15 ); Furthermore, the two sets of locking components 7 can respectively lock the positions of sliding door 101 and sliding door 202.

[0039] The locking assembly 7 is simple and reliable in design, which can effectively improve the performance and safety of the double-opening sliding door 1. At the same time, the positioning cylinder 701 and the pin seat 702 are installed by bolt fixing, which is convenient for installation, disassembly and maintenance. It has strong practicality and operability in practical applications.

[0040] The adaptive compensation double-opening sliding door adjustment involves the following steps: S1: The tension sensor 308 monitors the tension transmitted from the self-compensating rod 309 to the tie rod 307 in real time. When the tension is abnormal, such as being too large or too small, the tension sensor 308 will feed the signal back to the control system. The control system will adjust the self-locking geared motor 312 according to the feedback signal to ensure that the tension detected by the tension sensor 308 is within the specified range, thus completing the adaptive compensation of the tension of the synchronous belt 303. S2: At the same time, the monitoring system 6 monitors the position information of the first sliding door 101 and the second sliding door 102 of the double-leaf sliding door 1 in real time, and accurately determines whether the current position of the first sliding door 101 and the second sliding door 102 meets the preset position requirements. S3: If the positions of Sliding Door 101 and Sliding Door 202 deviate, the opening and closing positions need to be adjusted. S4: First, taking the position of the second sliding door 102 as a reference, the distance sensor 601 of the monitoring system 6 accurately detects the position information of the second sliding door 102. Then, the drive motor 301 drives the second sliding door 102 to move to the closed position. Then, the locking component 7 locks the position of the second sliding door 102. S5: Then disconnect the connection between the plug door 2 102 and the synchronous belt 303, that is, de-energize the electromagnet 50205 and release the magnetic attraction between it and the iron plate 50204. Then the piston rod of the dual-shaft cylinder 50201 extends, the pressure frame 50202 moves upward, and the friction plate 50207 separates from the synchronous belt 303. S6: At this time, the distance sensor 601 of the monitoring system 6 accurately detects the position information of the sliding door 101, and then the drive motor 301 drives the sliding door 101 to move to the closed position. Then, the locking component 7 locks the position of the sliding door 101. S7: Then restore the connection between the two-screw gate 102 and the synchronous belt 303, that is, the piston rod of the dual-shaft cylinder 50201 retracts and drives the pressure frame 50202 to move downward, so that the friction plate 50207 presses tightly on the synchronous belt 303. At this time, the lower baffle 50203 and the friction plate 50207 form a pressing chamber for the synchronous belt 303. The friction plate 50207 uses the friction force generated by the fine anti-slip texture to effectively lock the synchronous belt 303. The electromagnet 50205 is energized and attracts the iron plate 50204, so that the position of the pressure frame 50202 is locked a second time. S8: At this point, the position of the double-opening sliding door 1, sliding door 101 and sliding door 2, is quickly corrected.
