Abstract
Description
Technical Field
[0001] The utility model relates to the field of elevator fault detection, in particular to an elevator remote fault detection device. Background Art
[0002] Elevator fault detection is a complex and crucial process, involving various inspections and tests. Among them, safety detection is of utmost importance. During the use of an elevator, the normal operation of the car can provide safety guarantees.
[0003] However, when the traditional elevator remote fault detection device is in use, there is a certain delay. When users make long-term incorrect operations, it is easy to cause elevator operation failures, and the current detection results cannot be timely fed back to the control background, thus easily leading to phenomena such as passengers being trapped in the elevator.
[0004] For example: as users press the elevator buttons randomly and forcefully block the elevator door from closing for a long time, it may cause chaos in the elevator control system, and then lead to abnormal descent and the problem of passengers being trapped. And these incorrect operation methods cannot be stopped in time. Summary of the Utility Model
[0005] The utility model discloses an elevator remote fault detection device, aiming to solve the technical problem that when the traditional elevator remote fault detection device is in use, there is a certain delay. When users make long-term incorrect operations, it is easy to cause elevator operation failures, and the current detection results cannot be timely fed back to the control background, thus easily leading to phenomena such as passengers being trapped in the elevator.
[0006] To achieve the above object, the utility model adopts the following technical solutions:
[0007] An elevator remote fault detection device includes a car body and a mounting block installed on an inner wall of one side of the car body. There are two car doors provided on an inner wall of one side of the car body. The device further includes: a detection mechanism: the detection mechanism includes fixed covers arranged on outer walls of both sides of the mounting block. Speed sensors are provided on inner walls of both fixed covers. Two mounting boxes are connected to an outer wall of one side of the mounting block. Mounting holes are provided on inner walls of the mounting boxes. Identification probes are provided on inner walls of the mounting holes. The identification probes face the car doors. A heat dissipation cover is provided at one end of the mounting hole away from the identification probe; a mounting mechanism: the mounting mechanism is arranged on the mounting block.
[0008] In this solution, the detection mechanism is installed at a high position inside the car using the mounting block. The recognition probe in the detection mechanism can detect the opening and closing status of the car door. During the specific use process, once the car door is blocked from closing for a long time, in addition to the car body itself emitting a warning sound, this information will also be transmitted to the background control room. The monitoring personnel will make judgments and give reminders through the monitoring inside the car body to avoid elevator circuit failures caused by the above behaviors. In addition, the speed sensors provided can also detect abnormalities during the elevator's ascending and descending processes, and at the same time, the abnormal information can be fed back to avoid the situation where the internal personnel of the elevator cannot contact the maintenance personnel in time after being trapped, thus improving safety protection.
[0009] In a preferred solution, the installation mechanism includes two first screws provided on the outer wall of one side of the fixed cover. First screw holes are provided on the outer walls of both sides of the mounting block. The first screws and the first screw holes are adapted to each other. The fixed cover and the mounting block are installed through a hinge. A support pad is installed on the inner wall of the fixed cover. Bases are provided at the bottoms of the two fixed covers.
[0010] The fixed cover provided can fix the two groups of speed sensors. At the same time, the installation in the form of screws is convenient for disassembly and maintenance. The two groups of speed sensors can better ensure the detection data and avoid information delay caused by the damage of one of them.
[0011] In a preferred solution, two limiting grooves are provided on the outer wall of one side of the mounting block. Connecting blocks are slidably connected to the inner walls of the two limiting grooves. A clamping plate is provided on the outer wall of one side of the connecting block. The clamping plate and the connecting block are both adapted to the limiting grooves. A second screw is installed on the outer wall of one side of the clamping plate. A second screw hole is provided on the inner wall of one side of the limiting groove. The second screw and the second screw hole are adapted to each other.
[0012] The limiting connection and the adapted embedding of the connecting block by the limiting grooves ensure the stable installation of the mounting block. At the same time, the increased concealment of the installation, combined with the relatively high installation position, effectively avoids some human interference and improves the stability during the use of the detection device.
[0013] As can be seen from the above, an elevator remote fault detection device includes a car body and a mounting block installed on the inner wall of one side of the car body. There are two car doors on the inner wall of one side of the car body. It also includes: a detection mechanism: the detection mechanism includes fixed covers arranged on the outer walls of both sides of the mounting block. Speed sensors are provided on the inner walls of both fixed covers. Two mounting boxes are connected to the outer wall of one side of the mounting block.

[0021] A remote elevator fault detection device disclosed by the present utility model is mainly applied to scenarios where traditional remote elevator fault detection devices have a certain delay during use. When users make long-term incorrect operations, it is easy to cause elevator operation failures, and the current detection results cannot be timely fed back to the control background, thus easily leading to phenomena such as elevator entrapment.
[0022] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in
[0023] FIGS.
[0024] Specifically, the detection mechanism is installed at a high position inside the car by using the mounting block 3. The identification probe 13 in the detection mechanism can detect the opening and closing conditions of the car door 4. During the specific use process, once the car door 4 is blocked from closing for a long time, in addition to the car body 1 itself emitting a warning sound, this information will also be transmitted to the background control room, and the monitoring personnel will make judgments and urge through the monitoring inside the car body 1 to avoid elevator circuit failures caused by the above behaviors.
[0025] In addition, the abnormal conditions during the elevator's ascending and descending processes can be detected by the provided speed sensors 8, and the abnormal information can be fed back at the same time, avoiding the situation where the internal personnel in the elevator cannot contact the maintenance personnel in time after being entrapped, and improving safety protection.
[0026] Among them, reflective coatings 5 are provided on the inner walls on one side of the two car doors 4. The recognition probe 13 corresponds to the reflective coating 5. The more prominent reflective coating 5 can effectively ensure the recognition result and avoid the failure of recognition response.
[0027] Referring to Figure 1 、 Figure 3 and Figure 4 In a preferred embodiment, the installation mechanism includes two first screws provided on the outer wall on one side of the fixed cover 9. First screw holes are provided on the outer walls on both sides of the installation block 3. The first screws and the first screw holes are adapted to each other. The fixed cover 9 and the installation block 3 are installed by a hinge. A support pad 11 is installed on the inner wall of the fixed cover 9. Bases 12 are provided at the bottoms of the two fixed covers 9.
[0028] Specifically, the set fixed cover 9 can fix the two groups of speed sensors 8. At the same time, it is installed in the form of screws, which is convenient for disassembly and maintenance. The two groups of speed sensors 8 can better ensure the detection data and avoid information delay caused by the damage of one of them.
[0029] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 In a preferred embodiment, two limiting grooves 10 are provided on the outer wall on one side of the installation block 3. Connecting blocks 14 are slidably connected to the inner walls of the two limiting grooves 10. A clamping plate 15 is provided on the outer wall on one side of the connecting block 14. The clamping plate 15 and the connecting block 14 are both adapted to the limiting groove 10. A second screw is installed on the outer wall on one side of the clamping plate 15. A second screw hole is provided on the inner wall on one side of the limiting groove 10. The second screw and the second screw hole are adapted to each other.
[0030] Specifically, the limiting connection and fitting embedding of the connecting block 14 by the limiting groove 10 ensure the stable installation of the installation block 3. At the same time, the concealment of the installation is increased. Combined with the relatively high installation position, it effectively avoids some human interference and improves the stability of the detection device during use.
[0031] Referring to Figure 1 and Figure 2 In a preferred embodiment, side frames 2 are provided on the outer walls on both sides of the car body 1. The car body 1 is connected to the sliding track in the elevator shaft by relying on the side frames 2.
[0032] Working principle: When in use, the speed sensors 8 fixed inside the two fixed covers 9 can detect the lifting of the car body 1, and the identification probes 13 arranged in the installation box 6 can detect the opening and closing of the car door 4. Once the car door 4 fails to close within the specified time and is blocked, in addition to the car body 1 itself emitting a warning sound, this information will also be transmitted to the background control room. The monitoring personnel will make judgments and give reminders through the monitoring inside the car body 1 to avoid elevator circuit failures caused by the above behaviors. When a circuit failure occurs, the car body 1 is prone to rapid descent. During this process, the speed sensors 8 can detect the lifting of the car body 1, and abnormal situations will be fed back to achieve an efficient alarm function and avoid the occurrence of elevator entrapment.
[0033] As described above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. The substitution may be the substitution of some structures, devices, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution and the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
