[0010] The operating distance of the induction switch body is 0.5m.

[0011] As a further description of the above technical solution:

[0012] An alarm is arranged on the fixing seat, and the alarm is electrically connected to the mobile power source and the induction switch body.

[0013] As a further description of the above technical solution:

[0014] A wireless receiver is arranged in the elevator, and the wireless receiver is connected to the wireless transmitter by wireless communication.

[0015] As a further description of the above technical solution:

[0016] The fixing seat is provided with a slot, a flat pressing plate is slidably connected in the slot, a screw rod is screwed on the fixing seat, and the end of the screw rod is hinged to the flat pressing plate.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] In the utility model, a fixing base is installed on the top of the elevator, and a sensing switch body is installed on the fixing base. The sensing switch body monitors the situation above the elevator at all times, a mobile power supply supplies power to the sensing switch, and a wireless transmitter transmits a signal of the sensing switch body, thereby making it possible to construct the sensing switch body without complicated wiring. When the sensing switch body detects an obstacle above the elevator, the wireless transmitter sends a signal to the elevator, and the elevator stops lifting, thereby preventing the elevator from accidentally hitting the roof and preventing injuries to operators.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3The utility model provides a technical solution: a photoelectric induction switch for preventing high-altitude work from colliding with the roof, comprising a fixing seat 1, an induction switch body 2, a mobile power supply 3 and a wireless transmitter 4, wherein the fixing seat 1 is installed on the top of the lift, the induction switch body 2, the mobile power supply 3 and the wireless transmitter 4 are all installed on the fixing seat 1, and the induction switch body 2, the mobile power supply 3 and the wireless transmitter 4 are electrically connected, and the wireless transmitter 4 wirelessly sends the signal generated by the induction switch body 2 to the lift;

[0026] The induction switch body 2 is a diffuse reflection type photoelectric switch;

[0027] The operating distance of the induction switch body 2 is 0.5m;

[0028] The fixing base 1 is provided with an alarm 5, which is electrically connected to the mobile power source 3 and the induction switch body 2, and has a reminder function for the operators on the lift;

[0029] A wireless receiver 6 is provided in the lift, and a wireless communication connection is established between the wireless receiver 6 and the wireless transmitter 4, so as to facilitate a wireless communication connection between the wireless transmitter 4 and the lift;

[0030] The fixing seat 1 is provided with a slot 7, in which a flat plate 8 is slidably connected, and the fixing seat 1 is screwed with a screw rod 9, the end of which is hinged to the flat plate 8. The flat plate 8 can be driven to slide by turning the screw rod 9, so that the flat plate 8 can quickly clamp the structural parts of the elevator, thereby facilitating the rapid installation of the fixing seat 1 on the elevator.

[0031] Working principle: First, when installing the induction switch body 2, you only need to align the slot 7 of the fixing seat 1 with the structural parts of the elevator, and turn the screw rod 9 to drive the flat plate 8 to slide, so that the flat plate 8 can quickly clamp the structural parts of the elevator, and the installation of the induction switch body 2 can be completed. At this time, the mobile power supply 3 supplies power to the induction switch body 2, and establishes a wireless communication connection between the wireless transmitter 4 and the wireless receiver 6 of the elevator. Secondly, the operator remotely controls the elevator to rise. When there is an obstacle 0.5m above the elevator, the induction switch body 2 sends a signal to the wireless transmitter 4, and the wireless transmitter 4 sends the signal to the wireless receiver 6. After receiving the signal, the wireless receiver 6 controls the elevator to stop automatically. Finally, the signal of the induction switch body 2 will be sent to the alarm 5 synchronously. After receiving the signal, the alarm 5 sounds an alarm to remind the operator to lower his head.
