Description

Technical Field

[0001] This utility model relates to the field of freight elevator technology, specifically to a fault monitoring device for freight elevator transportation equipment based on multi-source sensors. Background Technology

[0002] Freight elevators are designed primarily for transporting goods and are usually accompanied by people. Freight elevator cars are characterized by their long and narrow shape. They are vertical lifts powered by electric motors, equipped with box-shaped cabins, and are fixed lifting devices that serve designated floors. They have one car that runs between at least two vertical rigid guide rails.

[0003] However, existing freight elevators cannot provide early warnings based on the weight, height, and width of the goods during use, leading to safety hazards when moving goods into the elevator. Therefore, they do not meet the current requirements. To address this, we propose a fault monitoring device for freight elevator transportation equipment based on multi-source sensors. Utility Model Content

[0004] The purpose of this invention is to provide a fault monitoring device for freight elevator transportation equipment based on multi-source sensors, in order to solve the problems mentioned in the background art, such as the inability of freight elevators to provide early warnings based on the weight, height, and width of goods during use, which leads to safety hazards when goods are moved into the elevator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fault monitoring device for freight elevator transportation equipment based on multi-source sensors, comprising a monitoring device body and multiple monitoring sensors. A base plate is detachably installed at the bottom of the monitoring device body. Two symmetrically distributed connecting blocks are fixed inside the bottom end of the monitoring device body. A positioning post is inserted through the bottom of the base plate. An insertion hole is provided through the inside of the connecting block. An elastic locking strip is fixed on the upper surface of the base plate. The positioning post is positioned between two adjacent elastic locking strips, and the elastic locking strip passes through the inside of the insertion hole.

[0006] Preferably, in the initial state, the top ends of two adjacent elastic snap-fit ​​strips are close to each other, and the outer surface of the top end of the positioning post is provided with two opposing compression strips.

[0007] Preferably, the bottom end of the positioning post is provided with a groove, and the inner side of the groove is provided with a rotating strip.

[0008] Preferably, a limiting ring is engaged at the bottom of the positioning post, the bottom of the limiting ring is flush with the bottom surface of the base plate, and a screw is provided through the inside of the limiting ring, and the limiting ring is connected to the base plate by the screw.

[0009] Preferably, the monitoring sensor includes an image acquisition sensor, an infrared ranging sensor, a torque sensor, and a photoelectric sensor.

[0010] Preferably, the image acquisition sensor is installed at the top of the elevator entrance, the infrared ranging sensor is installed at the center of the three side walls of the elevator, the photoelectric sensor is installed on both sides of the elevator entrance, and the torque sensor is installed on the reel of the elevator cable.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model achieves the connection and fixation of the base plate and the connecting block by passing the elastic snap strip on the upper surface of the base plate through the insertion hole. When the internal components of the monitoring device fail, the base plate can be removed simply by loosening the elastic snap strip and the connecting block, which facilitates the inspection, maintenance or replacement of the internal components of the monitoring device and improves the maintenance efficiency of the fault monitoring device.

[0013] 2. This utility model uses photoelectric sensors to monitor whether the vehicle transporting goods deviates when moving into the elevator, thus preventing the goods from colliding with the wall at the elevator entrance. An image acquisition sensor is used to monitor the movement of the goods and whether the top of the goods exceeds the height of the elevator entrance, while an infrared ranging sensor monitors the distance between the goods and the inner wall of the elevator, thereby ensuring the safety of the goods when transferring into the elevator.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, a fault monitoring device for freight elevator transportation equipment based on multi-source sensors includes a main body 1 and multiple monitoring sensors 3. A base plate 2 is detachably installed at the bottom of the main body 1. Two symmetrically distributed connecting blocks 5 are fixed inside the bottom end of the main body 1. A positioning post 4 is inserted through the bottom of the base plate 2. An insertion hole 6 is provided inside the connecting block 5. An elastic snap-fit ​​strip 9 is fixed on the upper surface of the base plate 2. The positioning post 4 is positioned between two adjacent elastic snap-fit ​​strips 9, and the elastic snap-fit ​​strip 9 passes through the inside of the insertion hole 6. The connection and fixation between the base plate 2 and the connecting block 5 are realized by the elastic snap-fit ​​strip 9 passing through the insertion hole 6 on the upper surface of the base plate 2. When the internal components of the main body 1 fail, the base plate 2 can be removed simply by loosening the elastic snap-fit ​​strip 9 from the connecting block 5, which facilitates the inspection, maintenance or replacement of the internal components of the main body 1 and improves the maintenance efficiency of the fault monitoring device.

[0021] In the initial state, the tops of the two adjacent elastic snap-fit ​​strips 9 are close to each other. The outer surface of the top of the positioning post 4 is provided with two opposing extrusion strips 10. The positioning post 4 rotates the extrusion strips 10, so that the extrusion strips 10 extrude or separate the elastic snap-fit ​​strips 9, so as to realize the elastic snap-fit ​​strips 9 adhering to the connecting block 5 or the elastic snap-fit ​​strips 9 resetting, thereby realizing the connection between the base plate 2 and the connecting block 5.

[0022] The bottom end of the positioning post 4 is provided with a groove, and the inner side of the groove is provided with a rotating strip 7. The presence of the rotating strip 7 makes it convenient for the operator to rotate the positioning post 4, thereby changing the state between the extrusion strip 10 and the elastic snap-fit ​​strip 9.

[0023] The bottom of the positioning post 4 is engaged with a limiting ring 8. The bottom of the limiting ring 8 is flush with the bottom surface of the base plate 2, and a screw is inserted through the limiting ring 8. The limiting ring 8 is connected to the base plate 2 by the screw. The positioning post 4 is restricted in position by the limiting ring 8, so as to ensure that the positioning post 4 will not fall off the bottom of the base plate 2 while it can rotate freely.

[0024] Monitoring sensor 3 includes an image acquisition sensor, an infrared ranging sensor, a torque sensor, and a photoelectric sensor. The image acquisition sensor is installed at the top of the elevator entrance, the infrared ranging sensor is installed at the center of the three side walls of the elevator, the photoelectric sensor is installed on both sides of the elevator entrance, and the torque sensor is installed on the winding shaft of the elevator cable. The photoelectric sensor monitors whether the vehicle transporting goods deviates when moving into the elevator, preventing the goods from colliding with the wall at the elevator entrance. The image acquisition sensor monitors the movement of the goods and whether the top of the goods exceeds the height of the elevator entrance. The infrared ranging sensor monitors the distance between the goods and the inner wall of the elevator. The torque sensor determines the total weight of the elevator by the winding torque of the steel cable and issues an overload alarm when the torque exceeds the maximum torque.

[0025] Working principle: When using AGV vehicles to transport goods into the elevator, the photoelectric sensors located on both sides of the elevator entrance remain operational. If the AGV vehicle deviates during its movement, causing the goods to obstruct the photoelectric sensors, it indicates that the edge of the goods exceeds the side of the elevator entrance. Continued movement poses a risk of the goods colliding with the wall. Simultaneously, the image acquisition sensor monitors the top of the goods in real time to determine whether the top height of the goods exceeds the height of the elevator entrance. At the same time, the infrared ranging sensor monitors the distance between the goods and the inner wall of the elevator. When the side of the goods exceeds the side of the elevator or the height of the goods is higher than the height of the elevator entrance, the photoelectric sensor or the image acquisition sensor sends an alarm to the AGV vehicle control center to provide early warning and remind staff to intervene manually to ensure the safety of the goods transfer process.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
