Description

Technical Field

[0001] The present invention relates to the technical field of elevator monitoring, and particularly to an elevator fault monitoring device. Background Art

[0002] In recent years, the elevator ownership in China has maintained a growth rate of more than 15% annually. Therefore, the current elevator usage in China is also very large. The probability of elevator failures during use is increasing. Due to the continuous development of information technology, the speed of information dissemination in life is getting faster and faster. Once an elevator fails, it will quickly attract social attention and cause adverse effects. Therefore, effective monitoring and rapid fault response have become increasingly important.

[0003] In order to monitor faults, for example, the Chinese invention patent with the publication number CN110015601 B provides a remote control system and method for analyzing elevator fault causes, belonging to the technical field of elevators. The remote control system includes an elevator control cabinet, a remote control device, an elevator monitoring device, and a remote monitoring server. The remote control device receives the elevator operation information in the elevator control cabinet and monitors faults in real time. When the remote control device detects a fault, it can analyze the fault cause and transmit real-time elevator fault images in combination with the real-time elevator operation information. The remote monitoring server can receive the real-time elevator fault analysis information sent by the remote control device to more deeply understand the cause of the fault and further implement fault handling. The remote control system and method for analyzing elevator fault causes provided by this invention enable technicians to analyze the root cause of the fault or accident without going on-site when a fault or accident occurs, and confirm the elevator operation signal during the fault remotely, improving the efficiency of fault handling.

[0004] For effective monitoring, a monitoring device is usually used to monitor the internal or external environment of the elevator. And in order to enable the monitoring device to have a larger monitoring range, the monitoring device is usually adjustable.

And through the set buffer component, the impact generated when the elevator moves up and down can be effectively buffered, so as to effectively ensure the stability of the monitoring head.

[0035] It should be noted that a circular groove adapted to the positioning block 1301 is provided at the top of the monitoring head 12. The circular groove is provided so that when the monitoring head 12 rotates, the positioning block 1301 will move inside the circular groove. In addition, the positioning assembly 13 is entirely located at the right rear of the driving motor 8. The top positioning block 1301 is slidably connected to the baffle 5. The top of the bottom positioning block 1301 is fixed to the hinge block 1302. The top of the hinge block 1302 is hinged to the positioning rod 1303 fixed to the top positioning block 1301.

[0036] Supplementally, the cleaning assembly 16 includes a connecting component, a cleaning plate 1606, a first cleaning cotton 1607, a second cleaning cotton 1608, two stabilizing blocks 1609 and two connecting plates 1610. The inside of the left side wall of the water storage tank 14 is slidably connected to the stabilizing blocks 1609. The stabilizing blocks 1609 provided enable the cleaning plate 1606 to move stably. The left side of the stabilizing blocks 1609 is fixed to the cleaning plate 1606. The cleaning plate 1606 provided is an arc-shaped plate, so that when the monitoring head 12 moves, the cleaning assembly 16 can fit with the monitoring head 12. The back of the cleaning plate 1606 is fixed to the connecting plate 1610. The inside of the cleaning plate 1606 is fixed to the first cleaning cotton 1607. The left side of the cleaning plate 1606 is fixed to the second cleaning cotton 1608. A connecting component that fits with the connecting plate 1610 is fixed inside the water storage tank 14. The connecting component includes a connecting pipe 1601, a connecting block 1602, a connecting spring 1603, a connecting rod 1604 and a sealing block 1605. The connecting pipe 1601 is fixed to the inside of the left side wall of the water storage tank 14. The connecting block 1602 is fixed inside the connecting pipe 1601.

A sealing block 1605 that fits with the inner wall of the connecting pipe 1601 is fixed to the outer surface of the connecting rod 1604. The sealing block 1605 provided is used to seal the connecting pipe 1601.

[0038] Generally speaking, when the monitoring head 12 rotates, it will cause the monitoring head 12 to contact the cleaning plate 1606 and push the cleaning plate 1606 to move a certain distance. In addition, the positioning component 13 is entirely located at the right rear of the driving motor 8, enabling the monitoring head 12 to rotate completely until it contacts the cleaning plate 1606.

[0039] Please refer to Figures 3 to 4 , in this embodiment, the adjusting component 10 includes an adjusting block 1001, two adjusting rods 1002, two adjusting plates 1003, two reset springs 1004, and two connecting telescopic rods 1005. The outer surface of the extension rod is fixed to the adjusting block 1001, the inside of the adjusting block 1001 is fixed to the adjusting rod 1002, and the outer surface of the adjusting rod 1002 is slidably connected to the adjusting plate 1003. The provided adjusting rod 1002 enables the adjusting plate 1003 to move stably. The reset spring 1004 is fixed between the adjusting plate 1003 and the adjusting block 1001. The provided reset spring 1004 has strong rigidity and can prevent the adjusting plate 1003 from sliding easily.

[0040] Furthermore, the inside of the adjusting block 1001 is slidably connected to the connecting telescopic rod 1005 fixed to the extension block. The provided connecting telescopic rod 1005 is a conventional technical means and can change its length. After the extension block moves, the connecting telescopic rod 1005 can remain connected to it. The connecting telescopic rod 1005 is in contact with the adjusting plate 1003. Both the front and rear sides of the adjusting plate 1003 have inclined surfaces 1007. The provided inclined surfaces 1007 enable the connecting telescopic rod 1005 to push the adjusting plate 1003 to move. A limiting disc 1006 is fixed to the outer surface of the connecting telescopic rod 1005 and is located inside the adjusting block 1001. The provided limiting disc 1006 enables a part of the connecting telescopic rod 1005 to always be inside the adjusting block 1001.

[0041] Generally speaking, due to the strong rigidity of the reset spring 1004, it can prevent the adjusting plate 1003 from sliding easily. When the connecting telescopic rod 1005 cannot move, the adjusting plate 1003 will squeeze the reset spring 1004.

[0042] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present invention mainly aims to protect mechanical devices, so the control method and circuit connection of the present invention will not be explained in detail.

[0043] The working principle of the above embodiment is as follows:

[0044] (1) When the driving motor 8 is started, the extension rod inside the threaded telescopic rod 9 will rotate, causing the adjusting block 1001 to rotate together, and then causing the adjusting rod 1002 and the adjusting plate 1003 to rotate together. When the adjusting plate 1003 contacts the connecting telescopic rod 1005, due to the strong rigidity of the return spring 1004, the adjusting plate 1003 cannot easily slide on the outer surface of the adjusting rod 1002. Therefore, when the adjusting plate 1003 rotates, it will push the connecting telescopic rod 1005 to move together, causing the connecting telescopic rod 1005 to drive the extension block and the monitoring head 12 to rotate together, so that the monitoring head 12 completes the adjustment of the horizontal angle. When the extension block rotates, the limiting plate 11 will rotate together, and then the limiting plate 11 will contact the positioning rod 1303, restricting the rotation of the limiting plate 11 and thus restricting the rotation of the extension block. At this time, when the driving motor 8 rotates, all the torque driven by the driving motor 8 will be transmitted to the adjusting plate 1003, causing the inclined surface 1007 on the adjusting plate 1003 to squeeze the connecting telescopic rod 1005. As a result, the adjusting plate 1003 squeezes the return spring 1004 and slides on the outer surface of the adjusting rod 1002. After the adjusting plate 1003 moves, it will lose contact with the connecting telescopic rod 1005, so that the extension block will not rotate with the extension rod. Therefore, the threaded telescopic rod 9 adjusts its length due to the extrusion of the thread, pushing the end of the monitoring head 12 downward or pulling it upward. The other end of the monitoring head 12 is slidably connected to the positioning assembly 13, and the positioning rod 1303 cannot adjust its length, so that the monitoring head 12 will tilt to complete the adjustment of the vertical angle, thus eliminating the need to set multiple driving sources for driving and effectively saving production costs.

[0045] (2) When the monitoring head 12 rotates, it will contact the first cleaning cotton 1607 and the second cleaning cotton 1608, and push the cleaning plate 1606 to move to a certain extent. Then, the connecting plate 1610 will push the connecting rod 1604 and the sealing block 1605 to move, making the sealing block 1605 unable to seal the inside of the connecting pipe 1601. As a result, the water inside the water storage tank 14 will flow towards the first cleaning cotton 1607, wetting the first cleaning cotton 1607, which can effectively improve the cleaning efficiency. When the monitoring head 12 resets, it will pass through the second cleaning cotton 1608 again to clean the water stains. After the monitoring head 12 resets, the elastic potential energy of the connecting spring 1603 will cause the connecting rod 1604 and the sealing block 1605 to reset and seal the connecting pipe 1601 again.

[0046] (3) When the mounting plate 1 generates a certain vibration, it will cause the buffer rod to move downward, thereby squeezing the buffer spring and buffering the vibration to a certain extent. When it is necessary to disassemble the baffle 5, by pushing the baffle 5 and the connecting rod 401 upward, the buffer block moves upward to squeeze the buffer spring, and the connecting rod 401 and the connecting block 402 move upward, so that the connecting block 402 moves to the top of the mounting block 3. At this time, by rotating the control block 404, the connecting block 402 can be staggered from the mounting block 3, so that when the connecting rod 401 is pulled downward, the connecting block 402 will not be re-slidably connected to the mounting block 3, and thus the disassembly of the baffle 5 can be simply and effectively completed, making subsequent maintenance convenient.

[0047] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
