DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] As attached Figure 1 To Attachment Figure 6 As shown:

[0027] Embodiment 1: The present invention provides a portable elevator door mechanical strength testing device, comprising a main body 1, including a shell 101, mounting plates 102 arranged on both sides of the bottom of the shell 101, through holes 103 arranged in the mounting plate 102, and a battery 104 arranged in the shell 101; a testing mechanism 2, including a pressure component 201 arranged in the shell 101, a detection component 202 arranged on the pressure component 201, and a fixing component 203 arranged between the pressure component 201 and the detection component 202; a portable mechanism 3, arranged between the shell 101 and the mounting plate 102; and a control board 4, arranged on the top of the shell 101.

[0028] Specifically, the pressure-applying assembly 201 includes a motor 2011 disposed in the housing 101, a screw rod 2012 disposed at the output end of the motor 2011, a movable seat 2013 threadedly disposed on the screw rod 2012, a fixed plate 2015 disposed at the front end of the movable seat 2013, a pressure sensor 2014 disposed between the fixed plate 2015 and the movable seat 2013, and an extrusion plate 2016 disposed at the front end of the fixed plate 2015.

[0029] Furthermore, the detection assembly 202 includes a plurality of pressure sensors 2021 respectively disposed on the inner sides of the fixed plate 2015 and the movable seat 2013 , and a spring 2022 disposed between the pressure sensors 2021 .

[0030] Furthermore, the fixing assembly 203 includes a plurality of threaded blocks 2031 disposed on the rear end surface of the extrusion plate 2016, a plurality of threaded cylinders 2032 movably disposed in the fixing plate 2015, a gear 1 2033 disposed at the rear end of the threaded cylinder 2032, a gear ring 2034 movably disposed on the periphery of the movable seat 2013, a motor 2035 disposed on the movable seat 2013, and a gear 2 2036 disposed at the output end of the motor 2035.

[0031] The threaded barrel 2032 is matched with the threaded block 2031 , and the gear ring 2034 is meshed with the gear 1 2033 and the gear 2 2036 .

[0032] As can be seen from the above, when the inspection work is carried out, the device is fixed in front of the elevator door to be inspected, and then the motor 2011 is started. The motor 2011 will drive the screw rod 2012 to rotate, and then drive the movable seat 2013 together with the fixed plate 2015 and the extrusion plate 2016 to move in a straight line until the extrusion plate 2016 contacts the surface of the elevator door. At this time, the motor 2011 is continued to be started. At this time, the extrusion plate 2016 cannot move, and then the distance between the fixed plate 2015 and the extrusion plate 2016 is shortened until the threaded barrel 2032 contacts the threaded block 2031. At this time, the motor 2035 is started, and the motor 2035 will drive The moving gear 2036 rotates, and then drives the gears 1 2033 to rotate together through the transmission of the gear ring 2034, so as to thread the threaded barrel 2032 and the threaded block 2031 together, thereby limiting the relative position of the fixed plate 2015 and the extrusion plate 2016 to ensure the stability during the subsequent inspection work. At this time, the motor 2011 is continued to drive the extrusion plate 2016 to apply load pressure to the surface of the elevator door. The pressure sensor 1 2014 will detect and record the applied pressure data to ensure the accuracy of the inspection, which is convenient for personnel to inspect the mechanical strength of the elevator door;

[0033] After the pressure is applied, motor 1 2011 and motor 1 2035 are started at the same time. Motor 1 2011 will drive the fixed plate 2015 to move to the rear end, and motor 1 2035 will drive the threaded cylinder 2032 to rotate in the opposite direction, so that the threaded cylinder 2032 and the threaded block 2031 are threadedly separated, and the fixed connection state between the fixed plate 2015 and the extrusion plate 2016 is released. At this time, the spring 2022 will use its own elasticity to firmly squeeze the extrusion plate 2016 on the elevator door to make it in close contact. At this time, if the elevator door is deformed due to extrusion, it will cause the extrusion plate 2016 to deflect synchronously, so that the distance between various parts of the fixed plate 2015 and various parts of the extrusion plate 2016 changes, thereby causing the corresponding spring 2022 to expand and contract synchronously, and the pressure sensor 2 2021 will detect the stress change of the corresponding spring 2022. The staff can obtain the current deflection angle of the extrusion plate 2016 through the pressure changes detected by the pressure sensors 2 21, thereby obtaining the deformation of the elevator door surface, which is convenient for personnel to use.

[0034] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the portable mechanism 3 includes movable frames 301 arranged on both sides of the shell 101, the movable frames 301 pass through the shell 101 and are provided with threaded rods 308, a holding rod 303 arranged between the movable frames 301, a fixing block 309 arranged on the top of the mounting plate 102, and limit blocks 307 arranged on both sides of the mounting plate 102.

[0035] Specifically, the threaded rod 308 is threadedly connected to the fixed block 309, a limit bolt 302 is threadedly arranged on the movable frame 301, a retaining ring 305 is arranged at the front end of the shell 101 through the rotating frame 304, the retaining ring 305 is adapted to the holding rod 303, and an opening groove 306 is arranged on the bottom surface of the shell 101 outside the mounting plate 102. When it is necessary to detect the internal structure of the shell 101, it is only necessary to swing the rotating frame 304 to offset the mounting plate 102 and the opening groove 306, and the internal situation of the device can be observed through the opening groove 306, and the limit block 307 will limit the movable range of the mounting plate 102.

[0036] As can be seen from the above, when not in use, the device can be lifted up as a whole by holding the holding rod 303, thereby improving the flexibility and portability of the device. When it is needed for inspection, after placing the device at the work site, the clamping ring 305 can be rotated up and down by the rotating frame 304, so that the clamping ring 305 is separated from the holding rod 303, and the limited state of the holding rod 303 is released, and then the clamping ring 305 is rotated upward with the threaded rod 308 as the axis until the movable frame 301 is perpendicular to the ground. During the process, the threaded rod 308 will rotate synchronously, and the threaded connection relationship between the threaded rod 308 and the fixing block 309 can drive it to move together with the mounting plate 102, so that in the process of lifting the holding rod 303, the two mounting plates 102 are ejected from both sides of the shell 101 together, and the staff can use the external bolts to pass through the through hole 103 to connect to the ground, so as to fix the position of the device and ensure the stability during the inspection work;

[0037] When the movable frame 301 is adjusted to be perpendicular to the ground, the holding rod 303 can be held to lift the device horizontally upward as needed to fine-tune the working position. After completing the position adjustment, the device can be lowered horizontally. After the inspection work is completed, the movable frame 301 can be rotated back to the initial position, and then the clamping ring 305 can be rotated and engaged on the holding rod 303 through the rotating frame 304 to limit the position of the holding rod 303. At this time, the holding rod 303 can be held and pulled up to fit the device to the outside of the thigh. The device is small and compact as a whole, flexible and portable, and it is convenient for personnel to fine-tune the device after placing it in the working position. The movement range is small, which saves time and effort and is convenient for personnel to use.

[0038] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the control board 4 includes a control module, and a data acquisition module, a data processing module, a data storage module and a display module connected to the control module.

[0039] As can be seen from the above, the data acquisition module will collect the pressure data detected by pressure sensor 1 2014 and pressure sensor 2 2021 when working, and transmit the data to the data processing module. The data processing module will establish a mathematical model and input the collected data into the established mathematical model in real time to obtain the deflection angle of the extrusion plate 2016, and then know the deformation of the elevator door surface. The data is then transmitted to the control module to use the storage module to store the detection data to avoid data loss, and the display module is used to display the data for easy viewing by the staff.
