Description

Technical Field

[0001] This invention belongs to the field of elevator landing door testing technology, specifically an elevator landing door strength testing device. Background Technology

[0002] Elevator landing doors are the doors between the elevator car and the floor, typically used to separate the elevator car and the floor space to ensure safety and prevent accidents. Elevator landing doors are usually made of metal or other sturdy materials, providing a certain degree of barrier and protection. Samples of the landing doors produced are usually selected for strength testing to determine the quality of the finished product.

[0003] Existing elevator landing door strength testing devices, when used for testing large-volume and heavy landing doors, typically require transporting multiple sets of sample landing doors to the vicinity of the testing device, and then lifting, positioning, and unloading each door individually. However, for large-volume and heavy elevator landing doors, continuous transport and positioning are difficult. When testing the strength of multiple sets of sample landing doors, it is difficult to complete the operation quickly from multiple angles, including lifting, positioning, adjustment, and unloading. The entire strength testing process, especially for impact strength testing, is also subject to door bouncing and shifting during impact. The entire testing process is time-consuming and labor-intensive, and it is difficult to sample and test landing doors on-site in a timely manner. The repeated transport of a large number of sample landing doors is troublesome, the on-site testing is difficult, the efficiency is low, and the usage effect is unsatisfactory.

[0004] In addition, when some sample door panels have quality defects, such as bending deformation and dents, the structural strength of the sample is affected. This makes it impossible to represent the strength of door panels on the production line. The data obtained from impact testing is subject to defect interference and cannot represent the strength standard of door panels under normal quality, thus affecting the actual testing accuracy. Summary of the Invention

The threads on the outer surface of the threaded rod are symmetrical. The clamping plates are symmetrically positioned on the threaded rod. The clamping assembly also includes a motor, and the output shaft of the motor is fixedly connected to the threaded rod.

[0008] Preferably, the movable support includes a side frame, a movable support platform, a second electric push rod, and a capacitive touch sensor. The side frame is fixedly connected to the support frame and communicates with the sleeve interface. The movable support platform is movably sleeved on the side frame. The fixed end of the second electric push rod is fixedly installed in the side frame, and the movable end of the second electric push rod is fixedly connected to the movable support platform. The sleeve interface is located on the movable path of the movable support platform. The capacitive touch sensor is fixedly installed on the top surface of the movable support platform, and the top surface of the capacitive touch sensor is horizontally aligned with the top surface of the movable support platform.

[0009] Preferably, the shockproof fixing part includes a mounting frame, a fixing rod, and a spring. The mounting frame is fixedly connected to the inner side of the movable frame, the fixing rod is movably sleeved in the mounting frame, the spring is located in the mounting frame, and the lower end of the spring is fixedly connected to the fixing rod.

[0010] Preferably, the movable frame has a connecting cavity inside, and a connecting opening is provided at the top of the inner side of the movable frame. The upper and lower ends of the connecting opening are respectively connected to the connecting cavity and the mounting frame. The upper end of the first spring passes through the connecting opening and is fixed in the connecting cavity. The connecting cavity is connected to the connecting curved tube.

[0011] Preferably, the distribution component includes a connecting frame, a sleeve, and an adapter sleeve. The connecting frame is fixedly connected to the front of the support frame, and the sleeve and adapter sleeve are fixedly connected to the top and bottom of the connecting frame, respectively, and keep their axes aligned.

[0012] Preferably, the outer surface of the connecting curved tube is provided with a through hole, the through hole is located near the lower end of the connecting curved tube, the lower end face of the connecting curved tube is sealed, the lower end of the connecting curved tube passes through the sleeve and the connecting frame and is movably sleeved in the adapter sleeve, and an internal sleeve block is fixedly sleeved in the connecting frame.

[0013] Preferably, the linkage component includes a mounting cavity, a push plate, a contact plate, a second spring, and a limiting frame. The mounting cavity is located on the front of the support frame and communicates with the connecting frame. The push plate is movably sleeved in the mounting cavity.

[0014] Preferably, the support frame is provided with support legs at both ends, and the bottom of the support legs is provided with casters.

[0015] The beneficial effects of this invention are as follows: 1. This invention utilizes a lifting movable frame with a clamping component added to the bottom to directly grasp the door to be tested when it falls to the ground. Combined with a laterally adjustable movable support platform, after grasping and suspending the door to a designated position, the platform is moved laterally under the door, completing the rapid grasping and supporting positioning of the door. Simultaneously, the lateral movement of the support platform and the compression of the linkage component, along with the distribution component and connecting curved pipe, further compress the internal hydraulic oil into the shock-absorbing fixing part. While completing the upward grasping and bottom support of the door, the fixing rod quickly and automatically moves downward, synchronously pressing and fixing the grasped door to the top of the movable support platform. To achieve rapid positioning and testing of sampled floor doors, especially for larger doors, a movable support frame is used to quickly grasp and position any door to be tested, solving the problem of difficult grasping and positioning of large-volume doors. Simultaneously, the movement of the movable support platform moves the fixing rod, increasing the vertical clamping force on top of the lateral clamping and bottom support during impact testing of sample doors. This prevents the door from jumping or vibrating during impact testing, maintaining stability during continuous impact testing and improving testing quality. In actual floor door testing, this system achieves rapid grasping, positioning, and enhanced fixation, resulting in high batch testing efficiency and ease of use.

[0016] 2. This invention utilizes the lateral movement of a movable support platform, combined with the height control of the movable frame's gripping of the door, to ensure that the movable support platform slides into position along the bottom of the door under test. While providing bottom support, it employs capacitive touch sensors mounted on the top of the movable support platform. A dense array of these sensors detects defects at the bottom of the door as it slides along the bottom. When the overall structure of the door is bent or locally dented, the densely arrayed capacitive touch sensors may not make contact, thus quickly determining the bottom level of the door even without sensing the bottom surface. For doors with severe bottom deformation defects, subsequent impact testing is canceled to avoid interference from the actual impact test values. This invention achieves both quality inspection of the sample door and allows for quality control of the generated doors as needed. The operation is simple and the testing is convenient.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 11 As shown, this embodiment of the invention provides an elevator landing door strength testing device, including a support frame 1, a movable frame 2 inside the support frame 1, a side plate 3 fixedly connected to the side of the movable frame 2, a first electric push rod 4 fixedly connected to the top surface of the support frame 1, the movable end of the first electric push rod 4 fixedly connected to the side plate 3, an impact testing mechanism 5 fixedly installed inside the movable frame 2, a clamping assembly 6 at the bottom end of the movable frame 2, a sleeve interface 7 opened on the side of the support frame 1, a movable support part 8 fixedly installed on the side of the support frame 1, a distribution assembly 12 fixedly installed on the front of the support frame 1, a linkage assembly 15 on the inner side of the support frame 1, the linkage assembly 15 being connected to the distribution assembly 12, a connecting curved pipe 13 fixedly connected to the top of the support frame 1, the lower end of the connecting curved pipe 13 being movably sleeved in the distribution assembly 12, and a shock-absorbing fixing part 9 on the inner side of the movable frame 2 being connected to the connecting curved pipe 13.

[0021] Example 1: In use, the pusher is moved to the door to be tested, keeping the door on the ground. The device is moved directly above the door, and the first electric push rod 4 is activated, causing the movable frame 2 to move downwards. This causes the clamping assembly 6 at the bottom of the movable frame 2 to move downwards until it contacts the ground, with the clamping plate 63 on the clamping assembly 6 positioned outside the door. The motor in the clamping assembly 6 is activated, causing the threaded rod 61 to rotate. This causes the clamping plates 63 on both sides of the threaded rod 61 to move closer together and clamp the door. After clamping the door, the first electric push rod 4 is activated and reset. The movable frame 2, clamping the door, moves upwards into the support frame 1, and simultaneously the connecting curved tube 13 moves upwards along the inside of the distribution assembly 12. When it reaches its position, the through hole 14 is located in the connecting frame. In step 121, with the landing door suspended, the second electric push rod 83 in the movable support part 8 is activated. The movable support platform 82 is inserted into the inside of the support frame 1 along the sleeve interface 7 and moves downward along the bottom surface of the landing door. As the movable support platform 82 gradually squeezes the linkage component 17, the contact plate 153 drives the push plate 152 to compress the second spring 154. The internal hydraulic oil is pressed into the connecting curved pipe 13 along the through hole 14 and squeezed into the shockproof fixing part 9 through the connecting cavity 10 and the connecting port 11. The first spring 93 is stretched, and the fixing pressure rod 92 presses the landing door downward. The bottom of the landing door is supported by the movable support platform 82 after it has moved into place. The impact detection mechanism 5 is activated to impact the landing door downward to complete the impact strength detection. During the impact detection process, the landing door remains stable and does not shift.

[0022] First, by utilizing the lifting movable frame 2 in conjunction with the clamping component 6 added at the bottom, the door to be tested can be directly grasped when it falls to the ground. Combined with the laterally adjustable movable support platform 82, after grasping and suspending the door to a designated position, the movable support platform 82 is moved laterally to below the door, completing the rapid grasping and support positioning of the door to be tested. Simultaneously, using the lateral movement of the movable support platform 82 and the compression of the linkage component 15, the internal hydraulic oil is further compressed into the shock-absorbing fixing part 9 through the distribution component 12 and the connecting curved pipe 13. While completing the upward grasping and bottom support of the door to be tested, the fixing pressure rod 92 is quickly and automatically moved downward, synchronously pressing and fixing the grasped door to the movable support platform. The top of the 82 allows for rapid positioning and detection of sample doors. For larger doors, the movable support frame 1 enables rapid gripping and positioning of any door to be tested, solving the problem of difficult gripping and positioning of large doors. Simultaneously, the movable support platform 82 moves to support the door while simultaneously fixing the pressure bar 92. When performing impact testing on sample doors, the vertical clamping force is added to the horizontal clamping and bottom support to prevent the door from jumping or vibrating during impact testing, maintaining stability during continuous impact testing and improving testing quality. In actual door testing, rapid gripping, positioning, and enhanced fixing are achieved, resulting in high batch testing efficiency and ease of use.

[0023] Example 2: When the landing door is clamped and suspended, as the movable support platform 82 moves, the movable support platform 82 slides along the bottom surface of the suspended landing door and moves towards the bottom of the landing door to be tested. Multiple sets of capacitive touch sensors 84 arranged in an array on the top surface of the movable support platform 82 sense contact with the landing door. When some capacitive touch sensors fail to sense contact, it is determined that there is a deformation defect at the bottom of the landing door. The landing door to be tested is replaced and the next set of tests is performed.

[0024] First, by utilizing the lateral movement of the movable support platform 82, in conjunction with the height control of the gripping of the door by the movable frame 2, the movable support platform 82 is ensured to slide into position along the bottom of the door to be tested, thus providing support for the bottom of the door. Simultaneously, the capacitive touch sensors 84 mounted on the top of the movable support platform 82, through a dense array of these sensors, detect defects at the bottom of the door as it slides along the bottom. When the overall structure of the door is bent or locally dented, the dense array of capacitive touch sensors 84 may not make contact. Therefore, even without sensing the bottom surface of the door, the horizontality of the door's bottom can be quickly determined. For cases with severe deformation defects at the bottom of the door, subsequent impact testing is cancelled to avoid interference from the actual impact test values. This achieves both quality inspection of the sample door and quality inspection of the generated door as needed. The operation is simple and the testing is convenient.

[0025] like Figure 2 , Figure 3 and Figure 7 As shown, the clamping assembly 6 includes a threaded rod 61, a limiting plate 62, and a clamping plate 63. The threaded rod 61 is rotatably mounted on the bottom end of the movable frame 2. The limiting plate 62 is fixedly connected to the bottom end of the movable frame 2 and located above the threaded rod 61. The clamping plate 63 is threadedly sleeved on the outer surface of the threaded rod 61. The threads on the outer surface of the threaded rod 61 are symmetrical from left to right. The clamping plate 63 is symmetrical from left to right on the threaded rod 61. The clamping assembly 6 also includes a motor, and the output shaft of the motor is fixedly connected to the threaded rod 61.

[0026] The clamping assembly 6 adapts to the size and position of the door, and the clamping plate 63 moves closer to achieve clamping and fixation.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9As shown, the movable support part 8 includes a side frame 81, a movable support platform 82, a second electric push rod 83, and a capacitive touch sensor 84. The side frame 81 is fixedly connected to the support frame 1 and communicates with the sleeve interface 7. The movable support platform 82 is movably sleeved in the side frame 81. The fixed end of the second electric push rod 83 is fixedly installed in the side frame 81, and the movable end of the second electric push rod 83 is fixedly connected to the movable support platform 82. The sleeve interface 7 is located on the movable path of the movable support platform 82. The capacitive touch sensor 84 is fixedly installed on the top surface of the movable support platform 82, and the top surface of the capacitive touch sensor 84 is level with the top surface of the movable support platform 82.

[0028] The movable support 82 is moved along the socket 7 when needed by the movable support part 8, and the bottom of the door is supported. The movable support 82 is provided with a sliding plate on the side, which slides and engages with the sliding groove on the inner wall of the support frame 1 to maintain sliding stability. The dense array of capacitive touch sensors 84 senses whether there are defects on the bottom surface of the door when it slides along the ground of the door. When there is a dent or complete deformation, some capacitive touch sensors 84 do not make contact and have no sensing value, thus determining that the specific model of the capacitive touch sensor 84 is TS04P SOP-14.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the shockproof fixing part 9 includes a mounting frame 91, a fixing rod 92, and a spring 93. The mounting frame 91 is fixedly connected to the inner side of the movable frame 2. The fixing rod 92 is movably sleeved in the mounting frame 91. The spring 93 is located in the mounting frame 91. The lower end of the spring 93 is fixedly connected to the fixing rod 92. The movable frame 2 has a connecting cavity 10 inside. The top of the inner side of the movable frame 2 has a connecting opening 11. The upper and lower ends of the connecting opening 11 are respectively connected to the connecting cavity 10 and the mounting frame 91. The upper end of the spring 93 passes through the connecting opening 11 and is fixed in the connecting cavity 10. The connecting cavity 10 is connected to the connecting curved pipe 13.

[0030] By utilizing the downward movement of the fixed pressure rod 92 in the shockproof fixing part 9 to press down on the floor door, and in conjunction with the clamping force of the floor door, the floor door is fixed and supported on the top of the movable support platform 82 from both longitudinal and transverse directions, reducing vibration and bouncing during impact testing, maintaining stability, and ensuring testing quality. The connecting cavity 10 and the connecting port 11 connect the connecting curved pipe 13 and the shockproof fixing part 9. The spring 93 automatically drives the fixed pressure rod 92 to move upward and reset when the oil pressure is removed.

[0031] like Figure 1 , Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the distribution assembly 12 includes a connecting frame 121, a sleeve 122, and an adapter sleeve 123. The connecting frame 121 is fixedly connected to the front of the support frame 1. The sleeve 122 and the adapter sleeve 123 are respectively fixedly connected to the top and bottom of the connecting frame 121 and keep their axes aligned. A through hole 14 is opened on the outer surface of the connecting curved tube 13. The through hole 14 is located near the lower end of the connecting curved tube 13. The lower end face of the connecting curved tube 13 is sealed. The lower end of the connecting curved tube 13 passes through the sleeve 122 and the connecting frame 121 and is movably fitted into the adapter sleeve 123. A connector is fixedly fitted in the connecting frame 121. The internal sleeve block and linkage assembly 15 include a mounting cavity 151, a push plate 152, a contact plate 153, a second spring 154, and a limiting frame 155. The mounting cavity 151 is opened on the front of the support frame 1 and is connected to the connecting frame 121. The push plate 152 is movably sleeved in the mounting cavity 151. The contact plate 153 is fixedly connected to the outer side of the push plate 152. The limiting frame 155 is fixedly sleeved in the mounting cavity 151 and movably sleeved with the contact plate 153. The second spring 154 is located in the mounting cavity 151 and is fixedly connected to the push plate 152. The other end of the second spring 154 is fixedly connected to the internal sleeve block.

[0032] By utilizing the movable connection between the distribution component 12 and the connecting curved pipe 13, and in conjunction with the opening of the through hole 14 on the side of the connecting curved pipe 13, when the movable frame 2 moves up and down, the hydraulic oil is only connected when the through hole 14 is connected to the connecting frame 121. That is to say, the automatic connection between the connecting curved pipe 13 and the linkage component 15 is achieved only after the floor door is moved to the specified height. Thus, by utilizing the contact plate 153 in the linkage component 15, the spring 154 is compressed when pressure is applied, and the internal hydraulic oil is squeezed out into the connecting curved pipe 13, thereby realizing the action of the anti-vibration fixing part 9 under hydraulic control.

[0033] The support frame 1 has support legs at both ends, and casters at the bottom of the support legs.

[0034] Casters (not shown in the figure) enable the device to move, adapt to the floor doors placed on the ground, adjust the position accordingly, and complete the gripping and lifting of the floor doors.

[0035] The working principle and usage process of this invention are as follows: During use, the pusher is moved to the door to be tested, keeping the door on the ground. The device is moved directly above the door, and the first electric pusher 4 is activated, causing the movable frame 2 to move downwards. This causes the clamping assembly 6 at the bottom of the movable frame 2 to move downwards until it contacts the ground, with the clamping plate 63 on the clamping assembly 6 positioned outside the door. The motor in the clamping assembly 6 is activated, driving the threaded rod 61 to rotate. This causes the clamping plates 63 on both sides of the threaded rod 61 to move closer together, clamping the door between them. After clamping the door, the first electric pusher 4 is activated and reset. The movable frame 2, clamping the door, moves upwards into the support frame 1, while simultaneously the connecting curved tube 13 moves upwards along the inside of the distribution assembly 12. When in position, the through hole 14 is located in the connecting frame 121, and the door remains suspended. The second electric pusher 83 in the movable support part 8 is activated, and the movable support platform 82 is inserted into the support frame 1 along the sleeve interface 7 and moves along the bottom surface of the door. As the movable support platform 82 gradually presses against the linkage component 17, the contact plate 153 drives the push plate 152 to compress the second spring 154. The internal hydraulic oil is pressed into the connecting curved pipe 13 along the through hole 14, and then squeezed into the shockproof fixing part 9 through the connecting cavity 10 and the connecting port 11. The first spring 93 is stretched, and the fixing rod 92 presses the door down. The bottom of the door is supported by the movable support platform 82 after it has moved into place. The impact detection mechanism 5 is activated to impact the door downward to complete the impact strength test. During the impact test, the door remains stable and does not shift. When the door is clamped and suspended, as the movable support platform 82 moves, it slides along the bottom surface of the suspended door and moves towards the bottom of the door to be tested. Multiple sets of capacitive touch sensors 84 arranged in an array on the top surface of the movable support platform 82 sense the contact with the door. When some capacitive touch sensors fail to sense contact, it is determined that there is a deformation defect at the bottom of the door. The door to be tested is replaced and the next set of tests is performed.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
