Description

Technical Field

[0001] This utility model relates to the technical field of elevators, and in particular to an elevator fault monitoring and alarm device. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. With the continuous development of cities across my country, there are more and more high-rise buildings, and the number of elevators installed is also increasing. With the widespread use of elevators, elevator malfunctions are also gradually increasing.

[0003] Existing vertical elevators generally lack timely monitoring of abnormal elevator operation. As a result, when elevator malfunctions or abnormalities occur, the monitoring room staff cannot detect them in time without reporting them, causing the elevator to remain in a faulty state for an extended period. Based on this, we propose an elevator fault monitoring and alarm device. Utility Model Content

[0004] To address the aforementioned problem where the lack of timely monitoring of elevator malfunctions leads to a situation where monitoring personnel cannot promptly detect elevator faults or abnormalities without reporting them, resulting in elevators remaining in a faulty state for extended periods, this invention provides an elevator fault monitoring and alarm device.

[0005] This utility model provides an elevator fault monitoring and alarm device, which adopts the following technical solution:

[0006] An elevator fault monitoring and alarm device includes an elevator car and a wall, with the wall located on one side of the elevator car. A top box is installed on the top of the elevator car. A monitoring component is installed on the left end of the top wall inside the top box, and a lateral movement component is installed on the right end of the top wall inside the top box. A mounting block is installed at the bottom of the lateral movement component. An alarm component is installed between the mounting block and the elevator car. A movable rod is connected to the right side of the mounting block. The end of the movable rod opposite to the mounting block extends out of the top box and is fitted with a movable seat. A fixing block is installed on the side of the wall near the top box, and a ventilation component is installed on the left end of the top of the elevator car.

[0007] By adopting the above technical solution, the monitoring component senses the elevator car. When the elevator car moves, the monitoring component controls the lateral movement component to work. The lateral movement component drives the movable rod to move to the right through the mounting block. If the elevator car stops at the correct position, the movable seat contacts the fixed block, and the movement of the mounting block is restricted. If the elevator car stops at the incorrect position, the movable seat and the fixed block are misaligned, and the movement of the mounting block is not restricted. When the mounting block moves to the rightmost end, the alarm component can be activated to sound an alarm, reminding the user to evacuate the elevator in time or not to board the elevator.

[0008] Optionally, the lateral movement assembly includes a support plate mounted on the inner top wall of the top box. A one-way threaded rod is connected between the support plate and the inner wall of the top box. An L-shaped support frame is mounted on the left side of the support plate. A motor is mounted between the L-shaped support frame and the support plate. The power output end of the motor is fixedly connected to the left end of the one-way threaded rod. A movable sleeve is screwed onto the outer wall of the one-way threaded rod. The bottom of the movable sleeve is fixedly connected to the top of the mounting block. A sliding rod is connected to one end of the top box near the one-way threaded rod. A sliding sleeve is fitted on the outer side of the sliding rod, and the bottom of the sliding sleeve is fixedly connected to the top of the movable sleeve.

[0009] By adopting the above technical solution, when the motor is working, it drives the one-way threaded rod to rotate. Under the sliding cooperation of the sliding sleeve and the sliding rod, the movable sleeve is limited. The rotation of the one-way threaded rod drives the movable sleeve to move to the right. When the movable sleeve moves to the right, it can drive the mounting block to move to the right.

[0010] Optionally, the monitoring component includes a controller and a speed sensor, wherein the output of the speed sensor is electrically connected to the input of the controller, and the output of the controller is electrically connected to the input of the motor.

[0011] By adopting the above technical solution, the speed sensor senses the elevator car. When the elevator car is moving, the controller controls the motor to shut off; when the elevator car is stationary, the controller controls the motor to start.

[0012] Optionally, the movable seat includes a second mounting plate, which is mounted on one end of the movable rod away from the mounting block. A pressure sensor is mounted on the side of the second mounting plate away from the movable rod, and a first mounting plate is mounted on the side of the pressure sensor away from the second mounting plate. The output end of the pressure sensor is electrically connected to the input end of the controller.

[0013] By adopting the above technical solution, when the first mounting plate contacts the fixed block, it can squeeze the pressure sensor, and the pressure sensor transmits the pressure signal to the controller, thereby controlling the motor to rotate in reverse.

[0014] Optionally, the alarm assembly includes a connecting plate, which is installed at the bottom of the mounting block. A contact block is installed on the right side of the connecting plate. An audible and visual alarm is installed at the right end of the top wall inside the elevator car. A contact switch is connected to the top of the audible and visual alarm, and the top of the contact switch extends into the inner cavity of the top box.

[0015] By adopting the above technical solution, when the installation block moves freely, when the connecting plate moves to the rightmost end, the contact block triggers the contact switch, which in turn turns on the audible and visual alarm and emits an alarm sound.

[0016] Optionally, a sliding assembly is provided between the connecting plate and the elevator car. The sliding assembly includes a pulley, which is installed at the bottom of the connecting plate. A slide rail is provided at the top of the elevator car, and the pulley and the slide rail are in a rolling connection.

[0017] By adopting the above technical solution, when the connecting plate moves, it can drive the pulley to slide inside the slide rail, thereby making the connecting plate move more smoothly.

[0018] Optionally, the ventilation assembly includes a smoke box, which is installed on the left end of the top wall inside the elevator car. An exhaust pipe is connected to the top of the smoke box, and the top of the exhaust pipe extends out of the elevator car. Support rods are symmetrically installed on the left and right ends of the top wall inside the smoke box, and a fan is installed between the two sets of support rods. An activated carbon adsorption mesh is installed inside the smoke box near the fan, and a high-efficiency filter is installed on the side of the activated carbon adsorption mesh away from the fan.

[0019] By adopting the above technical solution, the fan is turned on to draw in the smoke and draw it into the smoke chamber. The smoke passes through the activated carbon adsorption mesh and the high-efficiency filter mesh, which can effectively filter the inhaled gas and adsorb impurities. Then it is discharged into the atmosphere through the exhaust pipe, thereby purifying the air inside the elevator car.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] Through the coordinated arrangement of a fixed block, a movable seat, a mounting block, a monitoring component, an alarm component, and a lateral movement component, when the elevator car is stationary, the monitoring component senses that the wall is stationary and controls the lateral movement component to work. The lateral movement component drives the movable rod to move to the right through the mounting block. If the elevator car stops at the correct position, the movable seat contacts the fixed block. If the elevator car stops at the incorrect position, the movable seat and the fixed block are misaligned, which causes the alarm component to activate and sound an alarm, reminding the user to evacuate the elevator in time or not to board the elevator.

[0022] By using a combination of an exhaust pipe, a smoke chamber, a support rod, a fan, an activated carbon adsorption mesh, and a high-efficiency filter, the fan draws in the smoke and directs it into the high-efficiency filter. The activated carbon adsorption mesh and the high-efficiency filter effectively filter and adsorb impurities from the inhaled air before it is discharged into the atmosphere through the exhaust pipe, thus purifying the air inside the elevator car.

When the first mounting plate 601 contacts the fixed block 5, it can compress the pressure sensor 602. The pressure sensor 602 transmits a pressure signal to the controller 901, thereby controlling the motor 1202 to rotate in the opposite direction.

[0034] Please refer to the attached diagram in the instruction manual. Figure 1 A ventilation assembly 2 is installed at the left end of the top of the elevator car 3. The ventilation assembly 2 includes a smoke extraction box 202, which is installed on the left end of the inner top wall of the elevator car 3. An exhaust pipe 201 is connected to the top of the smoke extraction box 202, and the top of the exhaust pipe 201 extends out of the elevator car 3. Support rods 203 are symmetrically installed at the left and right ends of the inner top wall of the smoke extraction box 202. A fan 204 is installed between the two sets of support rods 203. An activated carbon adsorption net 205 is installed inside the smoke extraction box 202 near the fan 204, and a high-efficiency filter 206 is installed on the side of the activated carbon adsorption net 205 away from the fan 204. When the fan 204 is turned on, it draws in the smoke and into the smoke extraction box 202. The smoke passes through the activated carbon adsorption net 205 and the high-efficiency filter 206, which effectively filters and adsorbs impurities from the inhaled air. The smoke is then discharged into the atmosphere through the exhaust pipe 201, thereby purifying the air inside the elevator car 3.

[0035] Working principle: When the elevator car 3 moves, the speed sensor 902 senses the movement of the elevator car 3 and transmits the signal value to the controller 901. The controller 901 shuts off the motor 1202. When the elevator car 3 is stationary, the speed sensor 902 senses that the elevator car 3 is stationary. At this time, the controller 901 starts the motor 1202. When the motor 1202 is working, it drives the one-way threaded rod 1204 to rotate. Under the sliding cooperation of the sliding sleeve 1206 and the sliding rod 1207, the movable sleeve 1205 is limited. The rotation of the one-way threaded rod 1204 drives the movable sleeve 1205 to move to the right. When the movable sleeve 1205 moves, it drives the movable rod 7 to move to the right through the mounting block 8. The movable rod 7 drives the movable seat 6 to move to the right.

[0036] If the elevator car 3 stops in the correct position, the movable seat 6 will contact the fixed block 5 when it moves to the right. At this time, the movement of the mounting block 8 will be restricted, the pressure sensor 602 will be squeezed, and the pressure signal value will be transmitted to the controller 901. The controller 901 will control the motor 1202 to rotate in the opposite direction and drive the movable sleeve 1205 to reset. If the elevator car 3 stops in the wrong position, the movable seat 6 will move to the right without obstruction, which will in turn allow the mounting block 8 to move to the right without obstruction. The movement of the mounting block 8 will drive the connecting plate 1001 to move to the right. When the connecting plate 1001 moves to the rightmost end, it will trigger the contact switch 1004 through the contact block 1002, which will activate the audible and visual alarm 1003 to sound an alarm, reminding the user to evacuate the elevator in time or not to board the elevator.

[0037] At the same time, the fan 204 is turned on to draw in the smoke and draw it into the smoke chamber 202. When the smoke passes through the activated carbon adsorption net 205 and the high-efficiency filter net 206, the inhaled gas can be effectively filtered and impurities adsorbed. Then it is discharged into the atmosphere from the exhaust pipe 201, thereby purifying the air inside the elevator car 3.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
