DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0020] The present utility model provides a technical solution: As Figures 1 to 4As shown in the figure, in this embodiment, a multifunctional fault warning sensor includes a vibration sensor 1. A cable 7 is provided at the tail of the vibration sensor 1, and the other end of the cable 7 is connected to a power supply. A connecting plate 2 is fixedly installed at the bottom of the vibration sensor 1, and a signal transmitter 4 is fixedly connected to the upper end of the vibration sensor 1. An alarm 5 is provided on the signal transmitter 4, and a temperature sensor 6 is provided on the side of the signal transmitter 4. The temperature sensor 6 is relatively movable with respect to the signal transmitter 4 through an adjusting mechanism.

[0021] Among them, the adjusting mechanism is composed of a connecting rod 8, a mounting sleeve 9 and an adjusting rod 12. The connecting rod 8 is fixedly connected to the side wall of the signal transmitter 4. The end of the connecting rod 8 is fixedly connected to the mounting sleeve 9. The adjusting rod 12 is slidably inserted into the interior of the mounting sleeve 9. The temperature sensor 6 is fixedly connected to the bottom of the adjusting rod 12. A fixing mechanism is provided between the adjusting rod 12 and the mounting sleeve 9. The fixing mechanism includes a locking bolt 11. A locking hole 10 penetrating the mounting sleeve 9 is provided on the outer wall of the mounting sleeve 9. The locking bolt 11 is provided in the locking hole 10, and the locking bolt 11 is connected to the locking hole 10 by threaded cooperation. A plurality of mating holes 13 are provided on the adjusting rod 12.

[0022] During use, the locking bolt 11 is sequentially passed through the locking hole 10 and the mating hole 13, and the adjusting rod 12 can be fixed inside the mounting sleeve 9, so as to fix the temperature sensor 6 at the bottom of the adjusting rod 12. When it is necessary to adjust the distance between the temperature sensor 6 and the elevator motor, the locking bolt 11 can be inserted into different mating holes 13, so as to realize the position adjustment of the temperature sensor 6.

[0023] Among them, the plurality of mating holes 13 are arranged in a linear array, and the inner diameter of the mating hole 13 is equal to the diameter of the locking bolt 11.

[0024] With such a setting, it can be ensured that the adjusting rod 12 can adjust its position at equal intervals.

[0025] The vibration sensor 1 and the signal transmitter 4 are electrically connected through an internal wire, and the temperature sensor 6 and the signal transmitter 4 are electrically connected through an external wire 14.

[0026] Among them, a plurality of fixing holes 3 are respectively provided on both sides of the connecting plate 2.

[0027] Through the cooperation of the fixing holes 3 and the peripheral bolts, the device can be fixed on the elevator motor to be detected.

[0028] The present utility model provides a multifunctional fault warning sensor, and the specific working principle is as follows:

[0029] In use, the device can be fixed on the elevator motor to be detected through the cooperation of the fixing hole 3 and the peripheral bolt. When the vibration amplitude of the elevator motor shows a large fluctuation compared with the normal state, it indicates that the elevator motor starts to malfunction. At this time, the vibration sensor will transmit a signal to the signal transmitter 4, and the alarm 5 on the signal transmitter 4 will sound an alarm. At the same time, the signal transmitter 4 will send a signal to the pager carried by the staff, so as to quickly remind the staff to repair the elevator motor. Meanwhile, through the set temperature sensor 6, the temperature around the elevator motor can be monitored in real time. When the temperature around the elevator motor shows too large a deviation from the preset temperature, it is easy to cause the motor to malfunction. At this time, the temperature sensor 6 will transmit a signal to the signal transmitter 4, thus ensuring that the staff can arrive in time to troubleshoot the elevator motor for faults.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
