Description

Technical Field

[0001] The present invention relates to the technical field of elevator door body testing, and in particular to an elevator door body structure durability testing device. Background Art

[0002] Elevator doors are one of the components in an elevator system that comes into direct contact with passengers most frequently. If the door structure is not robust or becomes fatigued or damaged during use, it can prevent the door from closing or opening properly, potentially leading to entrapment and personal injury. Elevators are typically designed for a lifespan of 10-20 years or even longer. Frequent daily opening and closing of doors can lead to problems such as metal fatigue and loose welds. Durability testing simulates long-term use to verify that the door structure can withstand the expected workload and maintain stable performance. Domestic and international standards have clear requirements for mechanical strength and opening and closing life of elevator doors. Durability testing is essential for meeting these standards. Thoroughly tested elevator door products offer higher market reliability and lower failure rates, effectively improving customer satisfaction, reducing maintenance costs, and helping elevator manufacturers establish a positive brand image. If defects in the door structure go undetected early, frequent failures may occur after commissioning, increasing repair costs and potentially disrupting the normal use of the elevator due to downtime, resulting in financial and reputational damage.

[0003] With the acceleration of urbanization and the increasing number of high-rise buildings, elevators, as vertical transportation tools, have become an indispensable device in modern buildings. The elevator door system, as the part that comes into direct contact with passengers during elevator operation, is particularly critical in terms of safety and reliability. The door structure is subjected to frequent opening and closing movements over a long period of time. Under the influence of factors such as continuous loads, vibrations, and environmental changes, it is prone to structural fatigue, deformation, and loosening, which can affect the normal operation of the elevator and even cause safety accidents. Therefore, durability testing of elevator door structures has become a key step in the design and verification of elevator products. Existing testing methods often rely on manual monitoring or semi-automatic operations, resulting in low test efficiency, poor repeatability, and difficulty in fully simulating actual operating conditions. To this end, there is an urgent need for elevator door structure durability testing equipment with a reasonable structure, precise control, and sustainable operation to achieve realistic simulation and evaluation of the door's long-term operating performance, thereby improving product quality and safety assurance capabilities.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs an elevator door structure durability testing device to solve the above technical problems. Summary of the Invention

[0005] The technical purpose to be achieved by the present invention is to design an elevator door structure durability testing equipment, which is driven by a driving motor. Under the cooperation of the active component and the driven component, the sliding mechanism reciprocates on the slide rail assembly to test the elevator door fixed on the sliding mechanism, thereby testing the durability of the elevator door structure.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] This elevator door structural durability tester is designed to systematically test the service life and structural stability of elevator doors, ensuring their safety and reliability during long-term, high-frequency use. The equipment primarily comprises a base, mounting plate, slide rail assembly, sliding mechanism, drive motor, active and passive components, and other key components. Its overall design is scientifically sound and suitable for testing elevator doors of various models.

[0008] The base provides a stable support foundation for the entire device and is installed on the ground to ensure stability and shock resistance. A mounting plate, mounted on the base, supports other functional components and possesses high strength and load-bearing capacity. The rail assembly, affixed to the mounting plate, guides the sliding mechanism in linear reciprocating motion along a specified direction, ensuring smooth and precise movement. The sliding mechanism, mounted above the rail assembly, simulates the opening and closing motion of the elevator door during testing.

[0009] The drive motor is mounted below the mounting plate. It uses electrical energy to rotate the output shaft, providing continuous power throughout the sliding process. The output of the drive motor is connected to the active component, which mechanically transmits power to the adjacent driven component, indirectly driving the sliding mechanism. A dedicated fixing assembly securely secures the elevator door under test to it, preventing loosening or shifting during testing, thereby improving test accuracy and repeatability.

[0010] During actual operation, the drive motor starts, rotating the active component. The active and driven components are linked via gears, connecting rods, or timing belts, driving the sliding mechanism to slide back and forth linearly on the rail assembly. This reciprocating motion simulates the frequent opening and closing of elevator doors during actual use. This allows for long-term, high-intensity testing and evaluation of mechanical fatigue, structural wear, and the durability of various components, providing a scientific basis for design optimization and quality control. The entire test equipment boasts a compact structure and stable operation, making it an efficient and reliable device for testing the durability of elevator doors.

[0011] The structure of the slide rail assembly is precisely designed, and it mainly includes parts such as the slide rail body, the fixed plate, the upper slide groove, the lower slide groove and the limit groove. The slide rail body is the core component, which is installed above the mounting plate to carry and guide the operation of the sliding mechanism. The fixed plates are installed on both sides of the slide rail body to enhance stability, fix the slide rail, and prevent the slide rail from shifting during long-term operation. The upper slide groove is arranged on the upper surface of the slide rail body to limit and guide the upper movement of the sliding mechanism; the lower slide groove is opened at the bottom of the slide rail body, and cooperates with the upper slide groove to form a three-dimensional sliding channel. The limit groove is opened on the inner side of the lower slide groove to limit the range of motion of the sliding mechanism and prevent it from exceeding the set trajectory, thereby ensuring the safety and accuracy of the movement process and effectively improving the reliability and service life of the test equipment.

[0012] The upper and lower slide grooves are designed with full consideration of the operational stability and structural stress of the sliding mechanism. Their height values are both set to half the height of the slide rail body, so that the slide grooves can maintain the strength and balance of the overall structure while ensuring the sliding space. Among them, the lateral length of the upper slide groove is longer than that of the lower slide groove, and is specifically set to 1.5 to 3 times the lateral length of the lower slide groove. Such a proportional design is conducive to improving the guiding accuracy of the sliding mechanism in the track and reducing the shaking amplitude, thereby improving the overall operational stability and durability. In addition, the cross-sectional shape of the limit groove is set to be semicircular, which can not only better accommodate limit components such as balls or limit blocks, but also play a role of flexible buffering and positioning during the sliding process, preventing the mechanism from offsetting or jamming, and improving the safety and accuracy of the operation of the entire equipment.

[0013] The sliding mechanism is the core structure for realizing the reciprocating motion during the durability test of the elevator door body. Its overall design is scientific and its structure is compact. It mainly includes multiple functional components such as a guide slider, a limit slider, a ball, a mounting base, a rotating pin and a fixing assembly. The guide slider is located in the middle part of the sliding mechanism and is the main component of the entire sliding mechanism. It plays the role of bearing, guiding and connecting. The limit slider is installed on the upper part of the guide slider to assist in the positioning and guiding of the ball, while limiting its range of motion to avoid offset. The ball is respectively installed on the two sides of the limit slider, and through cooperation with the upper and lower sliding grooves, it realizes low-friction and high-efficiency sliding motion, effectively improving the operational stability and sensitivity during the test.

[0014] The mounting base is set below the guide slider and is used to connect the entire sliding mechanism to other components and maintain structural stability. The rotating pin is located on the lower side of the mounting base and is a key component connecting the drive structure and the sliding mechanism, which can realize the conversion of rotational motion into linear sliding. The fixing component is installed on the top of the limit slider and is mainly used to firmly fix the elevator door body to be tested on the sliding mechanism to ensure that it will not loosen or fall off during the test, thereby ensuring the safety and reliability of the entire test process. The design of this sliding mechanism not only improves the operating efficiency of the test equipment, but also enhances the durability and stability during use, and is suitable for high-intensity repetitive testing scenarios.

[0015] The balls are evenly arranged in a linear array on both sides of the limit slider, which not only improves the guiding accuracy of the sliding mechanism within the slide rail but also effectively distributes the load generated during the sliding process. Each ball can rotate flexibly and freely within the limit slider, reducing friction during the reciprocating motion of the sliding mechanism, improving operational smoothness and the service life of the test equipment.

[0016] The fixing assembly has a compact structure and is installed above the limit slider. It is used to firmly fix the elevator door body under test to ensure its stability and safety during the test. The fixing assembly consists of a fixed base plate, a fixed baffle, a fixed spring and a fixed clamping block. Among them, the fixed base plate serves as a bearing base and is firmly installed on the upper surface of the limit slider to provide installation support. The fixed baffles are respectively arranged on the left and right sides above the fixed base plate, which play a role in positioning and restraining the clamping structure. The fixed spring is laterally arranged between the inner sides of the two fixed baffles and has good elastic recovery performance, which is used to provide clamping force. The fixed clamping block is installed on the inner side of the fixed spring and can move inward under the push of the spring to achieve clamping and fixation of the edge of the elevator door. This structure not only ensures the reliability of the clamping force, but also facilitates the disassembly and replacement of the test object, thereby improving the overall test efficiency and applicability.

[0017] The fixed baffle is designed as an L-shaped structure, which gives it better structural strength and installation adaptability. The L-shaped three-dimensional structure not only enhances the rigidity and deformation resistance of the fixed baffle, but also provides a reliable mounting surface for the installation of the fixed spring. The fixed spring can be firmly set horizontally between the inner side surfaces of the two L-shaped baffles, while maintaining the elastic clamping force, ensuring that it does not shift or loosen during long-term operation. In addition, the L-shaped baffle also forms a natural limiting boundary when in contact with the elevator door body, thereby effectively stabilizing the elevator door body that needs to be fixed and preventing it from shaking or shifting during the test. This structural design takes into account the reliability of the clamping function, as well as the convenience of use and the durability of the structure.

[0018] The active component is the core transmission structure for realizing the reciprocating motion of the sliding mechanism, which mainly includes an active shaft, an active gear, an active swivel and an active rotating rod. The active shaft is installed at the output end of the driving motor by means of rotation, and is used to transmit the rotational power of the motor to the subsequent structure. The active gear and the active shaft are coaxially arranged, and the two are tightly connected, so that the rotation of the motor can directly drive the gear to rotate, thereby driving the entire transmission system. The active swivel is installed on the side of the active gear and acts as an intermediate hub for connecting and transmitting power. Its special structural design helps to balance the rotational inertia and ensure smooth operation during rotation. The active rotating rod is installed on the side of the active swivel, one end of which rotates with the active swivel, and the other end is connected to the driven component or sliding mechanism, and converts circular motion into linear reciprocating motion, realizing high-frequency back and forth sliding of the sliding mechanism on the slide rail. The active component has a compact structure and high transmission efficiency. It is a key component of power transmission in the test equipment, ensuring the continuity and stability of the entire test process.

[0019] The driven assembly, designed to cooperate with the active assembly to further convert the rotational motion output by the motor into reciprocating linear motion of the sliding mechanism, primarily comprises a driven gear, a driven shaft, a driven rotating rod, and a driven cover. Specifically, the driven gear is mounted on the side of the active assembly and, by meshing with the active gear, achieves synchronous power transmission. The driven shaft, fixed to the side of the driven gear, receives the gear's rotational motion and transmits it to the rotating component at the next level. The driven rotating rod, mounted at the end of the driven rotating shaft and possessing a certain length and strength, provides a stable connection and transmits force during movement. A driven cover is mounted on one end of the driven rotating rod, protecting the rotating parts from dust and impurities, thereby enhancing the reliability and durability of the assembly. It is worth noting that the driven rotating rod and the active rotating rod are arranged on the same axis at their top ends, forming a coordinated motion trajectory during rotation. This effectively improves the synchronization and stability of the sliding mechanism's reciprocating motion, thereby ensuring efficient elevator door durability testing.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The present invention provides an elevator door structure durability test device with significant advantages such as reasonable structure, stable operation, and high test efficiency. First, by setting a linkage mechanism composed of a slide rail assembly, a sliding mechanism, an active assembly, and a driven assembly, the tested elevator door can achieve high-frequency and long-term reciprocating sliding in the equipment, truly simulating the working state of the elevator door during actual operation, thereby effectively evaluating its structural durability and service life. Secondly, the sliding mechanism adopts a combination design of a guide slider, a limit slider, and a linear ball, which greatly improves the smoothness and wear resistance during the sliding process, reduces the error caused by friction during the test, and ensures the accuracy of the test data. At the same time, an upper slide groove, a lower slide groove, and a limit groove are set inside the slide rail assembly to form a three-dimensional sliding guide path, so that the entire sliding process is controlled and safe, avoiding the occurrence of mechanism offset or jamming, and improving the reliability of the equipment operation.

[0022] (2) The fixing assembly in the present invention adopts an elastic clamping structure. Through the cooperation of the fixing spring and the clamping block, the elevator door to be tested can be quickly and firmly installed on the sliding mechanism, which not only improves the operating efficiency, but also ensures the reliability of the clamping, and avoids the test failure caused by the loosening of the door body during the test. The active and driven components realize the efficient conversion of rotational motion to linear sliding through the coaxial rotation structure. It has a compact structure and strong linkage. It is suitable for the testing needs of elevator door bodies of different specifications and types, and has good versatility and extensibility. At the same time, the addition of the driven cover improves the protection ability of the equipment, reduces the wear and failure rate, and extends the service life of the equipment. In summary, the present invention can not only significantly improve the quality control level of elevator door body products, but also provide an efficient and stable detection tool for elevator manufacturers, which has broad market application prospects and promotion value.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] like Figure 1-9 The figure shows an elevator door structure durability tester designed to systematically test the service life and structural stability of elevator doors to ensure their safety and reliability during long-term, high-frequency use. The device primarily comprises a base 1, mounting plate 2, slide rail assembly 3, sliding mechanism 4, drive motor 5, active assembly 6, and driven assembly 7, among other key components. Its overall design is scientific and rational, making it suitable for testing elevator doors of various models.

[0037] Base 1 provides a stable support foundation for the entire device and is installed on the ground to ensure its stability and shock resistance. Mounting plate 2, mounted on base 1, supports other functional components and possesses high strength and load-bearing capacity. Slide rail assembly 3, affixed to mounting plate 2, guides sliding mechanism 4 in linear reciprocating motion along a specified direction, ensuring smooth and precise movement. Slide mechanism 4, mounted above slide rail assembly 3, functions to simulate the opening and closing motion of the elevator door during testing.

[0038] like Figure 2 As shown, a drive motor 5 is mounted beneath the mounting plate 2. It uses electrical energy to rotate the output shaft, providing continuous power throughout the sliding process. The output of the drive motor 5 is connected to a driving component 6, which mechanically transmits power to an adjacent driven component 7, indirectly driving the sliding mechanism 4. A dedicated fixing assembly 46 is provided on the sliding mechanism 4 to securely fasten the elevator door under test, preventing loosening or shifting during testing and improving test accuracy and repeatability.

[0039] During actual operation, the drive motor 5 is activated, rotating the active assembly 6. This is then linked to the driven assembly 7 via gears, connecting rods, or timing belts, thereby driving the sliding mechanism 4 to slide back and forth linearly on the rail assembly 3. This reciprocating motion simulates the frequent opening and closing of elevator doors during actual use. This allows for long-term, high-intensity testing and evaluation of mechanical fatigue, structural wear, and the durability of various components, providing a scientific basis for design optimization and quality control. The entire test equipment boasts a compact structure and stable operation, making it an efficient and reliable device for testing the durability of elevator doors.

[0040] like Figure 4 As shown, the structure of the slide rail assembly 3 is precisely designed, and it mainly includes parts such as the slide rail body 31, the fixed plate 32, the upper slide groove 33, the lower slide groove 34 and the limit groove 35. The slide rail body 31 is a core component, which is installed above the mounting plate 2 and is used to carry and guide the operation of the sliding mechanism 4. The fixed plates 32 are respectively installed on both sides of the slide rail body 31, which play a role in enhancing stability, fixing the slide rail, and preventing the slide rail from shifting during long-term operation. The upper slide groove 33 is arranged on the upper surface of the slide rail body 31 to limit and guide the upper movement of the sliding mechanism 4; the lower slide groove 34 is opened at the bottom of the slide rail body 31, and cooperates with the upper slide groove 33 to form a three-dimensional sliding channel. The limit groove 35 is opened on the inner side of the lower slide groove 34 to limit the range of motion of the sliding mechanism 4, prevent it from exceeding the set trajectory, ensure the safety and accuracy of the movement process, and effectively improve the reliability and service life of the test equipment.

[0041] The upper and lower slide grooves 33 and 34 are designed with full consideration given to the operational stability and structural stress of the sliding mechanism 4. Their heights are both set to half the height of the rail body 31, so that the slide grooves maintain the strength and balance of the overall structure while ensuring sliding space. The lateral length of the upper slide groove 33 is longer than that of the lower slide groove 34, specifically set to 1.5 to 3 times the lateral length of the lower slide groove 34. This proportional design is conducive to improving the guiding accuracy of the sliding mechanism 4 in the track and reducing the shaking amplitude, thereby improving the overall operational stability and durability. In addition, the cross-sectional shape of the limit groove 35 is set to be semicircular, which not only can better accommodate limit components such as balls or limit blocks, but also can play a role in flexible buffering and positioning during the sliding process, preventing the mechanism from offsetting or jamming, and improving the safety and accuracy of the entire equipment operation.

[0042] like Figure 6 As shown, the sliding mechanism 4 is the core structure for realizing the reciprocating motion during the durability test of the elevator door body. Its overall design is scientific and its structure is compact. It mainly includes multiple functional components such as a guide slider 41, a limit slider 42, a ball 43, a mounting base 44, a rotating pin 45 and a fixing assembly 46. The guide slider 41 is located in the middle part of the sliding mechanism 4 and is the main component of the entire sliding mechanism 4. It plays the role of bearing, guiding and connecting. The limit slider 42 is installed on the upper part of the guide slider 41 to assist in the positioning and guiding of the ball 43, while limiting its range of movement to avoid deviation. The ball 43 is respectively installed on the two sides of the limit slider 42, and realizes low-friction, high-efficiency sliding motion by cooperating with the upper and lower sliding grooves 34, effectively improving the operating stability and sensitivity during the test.

[0043] The mounting base 44 is provided below the guide slider 41 and is used to connect the entire sliding mechanism 4 to other components and maintain structural stability. The rotating pin 45 is located on the lower side of the mounting base 44 and is a key component connecting the drive structure and the sliding mechanism 4, which can realize the conversion of rotational motion into linear sliding. The fixing assembly 46 is installed on the top of the limiting slider 42 and is mainly used to firmly fix the elevator door body to be tested on the sliding mechanism 4 to ensure that it will not loosen or fall off during the test, thereby ensuring the safety and reliability of the entire test process. The design of the sliding mechanism 4 not only improves the operating efficiency of the test equipment, but also enhances the durability and stability during use, and is suitable for high-intensity repetitive testing scenarios.

[0044] The balls 43 are evenly arranged in a linear array on both sides of the limit slider 42. This not only improves the guidance accuracy of the sliding mechanism 4 within the slide rail, but also effectively distributes the load generated during the sliding process. Each ball 43 can rotate flexibly and freely within the limit slider 42, thereby reducing frictional resistance during the reciprocating motion of the sliding mechanism 4, improving operational smoothness and the service life of the test equipment.

[0045] like Figure 7 As shown, the compact fixing assembly 46 is mounted above the limit slider 42 and serves to securely secure the elevator door under test, ensuring stability and safety during testing. The fixing assembly 46 consists of a fixing base 461, a fixing baffle 462, a fixing spring 463, and a fixing clamp 464. The fixing base 461 serves as a load-bearing foundation, securely mounted on the upper surface of the limit slider 42 and providing mounting support. The fixing baffles 462 are positioned on either side of the fixing base 461, positioning and restraining the clamping structure. The fixing spring 463, positioned transversely between the inner surfaces of the two fixing baffles 462, exhibits excellent elastic recovery properties and provides clamping force. The fixing clamp 464 is mounted inside the fixing spring 463 and, driven by the spring, moves inward to secure the elevator door edge. This structure ensures reliable clamping force while facilitating assembly, disassembly, and replacement of the test object, improving overall testing efficiency and applicability.

[0046] The fixed baffle 462 is designed as an L-shaped structure, which gives it better structural strength and installation adaptability. The L-shaped three-dimensional structure not only enhances the rigidity and deformation resistance of the fixed baffle 462, but also provides a reliable mounting surface for the installation of the fixed spring 463. The fixed spring 463 can be firmly arranged laterally between the inner side surfaces of the two L-shaped baffles, while maintaining the elastic clamping force, ensuring that it does not shift or loosen during long-term operation. In addition, the L-shaped baffle also forms a natural limiting boundary when in contact with the elevator door body, thereby effectively stabilizing the elevator door body that needs to be fixed and preventing it from shaking or shifting during the test. This structural design takes into account the reliability of the clamping function, as well as the convenience of use and the durability of the structure.

[0047] like Figure 8-9As shown, the active component 6 is the core transmission structure that realizes the reciprocating motion of the sliding mechanism 4. It mainly includes a driving shaft 61, a driving gear 62, a driving swivel 63, and an active rotating rod 64. The driving shaft 61 is mounted on the output end of the drive motor 5 in a rotatable manner and is used to transmit the motor's rotational power to the subsequent structure. The driving gear 62 is coaxially arranged with the active shaft 61 and the two are tightly connected, so that the rotation of the motor can directly drive the gear rotation, thereby driving the entire transmission system. The driving swivel 63 is mounted on the side of the driving gear 62 and serves as an intermediate hub for connecting and transmitting power. Its unique structural design helps to balance rotational inertia and ensure smooth operation during rotation. The active rotating rod 64 is mounted on the side of the driving swivel 63. One end rotates with the driving swivel 63, and the other end is connected to the driven component 7 or the sliding mechanism 4. It converts circular motion into linear reciprocating motion, realizing high-frequency back-and-forth sliding of the sliding mechanism 4 on the slide rail. This active component 6 has a compact structure and high transmission efficiency. It is a key component of power transmission in the test equipment, ensuring the continuity and stability of the entire testing process.

[0048] The driven component 7 is used to cooperate with the active component 6 to further convert the rotational motion output by the motor into the reciprocating linear motion of the sliding mechanism 4, and mainly includes a driven gear 71, a driven shaft 72, a driven rotating rod 73 and a driven cover 74. Specifically, the driven gear 71 is installed on the side of the active component 6, and realizes the synchronous transmission of power by engaging with the active gear 62. The driven shaft 72 is fixed to the side of the driven gear 71, and is used to undertake the rotational motion of the gear and transmit it to the rotating component of the next level. The driven rotating rod 73 is installed at the end of the driven shaft 72, has a certain length and strength, and plays a role in stabilizing the connection and transmitting force during the movement. A driven cover 74 is installed at one end. The driven cover 74 is used to protect the rotating part, prevent dust, impurities, etc. from entering, and improve the reliability and durability of the component operation. It is worth mentioning that the driven rotating rod 73 and the active rotating rod 64 are set to the same axis at the top, so that they form a coordinated motion trajectory during the rotation process, effectively improving the synchronization and stability of the reciprocating operation of the sliding mechanism 4, thereby ensuring the efficient implementation of the elevator door durability test.

[0049] During operation of the present invention, the tester installs the elevator door between the fixed clamps 464, and the fixed springs 463 push the fixed clamps 464 to squeeze and fix the two sides of the elevator door;

[0050] The driving motor 5 is started, driving the active shaft 61 to rotate. The active gear 62 rotates under the drive of the active shaft 61, and the driven gear 71 meshing with it also rotates. Since the active rotating rod 64 restricts the active gear 62 and the driven gear 71, and the active gear 62 is fixed by the active shaft 61 to rotate on a fixed axis, the driven gear 71 will rotate around the active gear 62. The driven cover 74 and the rotating pin 45 are installed together, thereby driving the sliding mechanism 4 to slide in the slide rail assembly 3; the sliding mechanism 4 performs multiple reciprocating motions to detect the durability of the elevator door structure.
