Detailed Description of the Preferred Embodiment

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] Referring to Figures 1-8 , a platform indicating device for a wind power tower crane elevator, which includes an operation platform 1, a steel wire rope 2, and a car 3. A trigger mechanism is installed on one side of the car 3. The trigger mechanism includes a trigger plate 4, a limit switch 5, and an indicator light 6. The trigger plate 4 is located on the side of the operation platform 1 close to the car 3. The limit switch 5 is installed on the car 3 through a bracket 7, and the indicator light 6 is arranged inside the car 3. During the operation of the car 3, the contact or separation between the limit switch 5 and the trigger plate 4 is used to control the indicator light 6 inside the car 3 to turn on or off, so as to indicate whether the car 3 has reached the corresponding operation platform 1.

[0032] Specifically, two pulleys 8 are arranged on the side of the bracket 7 close to the operation platform 1. Grooves are provided on the circumferential surface of the pulley 8, and the steel wire rope 2 passes through the grooves between the two pulleys 8. The steel wire rope 2 cooperates with the pulley 8 to play a guiding role.

[0033] In this embodiment, the operation platform 1 is arranged in several layers along the height direction of the tower barrel, and the trigger plate 4 is arranged in one-to-one correspondence with the several layers of operation platforms 1; the trigger plate 4 is of an isosceles trapezoid structure, and the long side of the trigger plate 4 is connected to the operation platform 1.

[0034] A guiding sleeve 9 is sleeved on the steel wire rope 2, and the guiding sleeve 9 is installed on the short side of the trigger plate 4. By sleeving the guiding sleeve 9 on the steel wire rope 2, it can be avoided that the steel wire rope 2 collides with or rubs against the operation platform 1 and causes damage.

[0035] Please refer to Figure 3 again. The guiding sleeve 9 includes a guiding part 901 and a connecting part 902. A through hole is provided in the center of the guiding part 901, and the steel wire rope 2 passes through the through hole. One end of the connecting part 902 far from the guiding part 901 is connected to the trigger plate 4.

[0036] Furthermore, both the upper and lower ports of the guiding part 901 are of a conical structure. It is convenient for the guiding sleeve 9 to pass through as the steel wire rope 2 passes through the grooves between the two pulleys 8.

[0037] As an implementable manner, the model of the limit switch 5 is Omron D4NA-412G. Specifically, the limit switch 5 includes a switch box 501 with a switch element built in. A rotating shaft 502 connected to the switch element is arranged on the switch box 501. A rotating seat 503 is arranged at the front end of the rotating shaft 502. A swing rod 504 is slidably connected to the rotating seat 503, and a roller 505 is arranged at the end of the swing rod 504.

[0038] Specifically, the switching element in the switch box 501 is connected to the indicator light 6 through a wire, so that the limit switch 5 is used to control the lighting or extinguishing of the indicator light 6. The overall structure is simple and the implementation cost is low.

[0039] The working principle of the present utility model is as follows:

[0040] During the operation of the car 3, please refer to Figure 7 and Figure 8 again. When the car 3 is between two adjacent working platforms 1, the roller 505 on the swing rod 504 does not contact the trigger plate 4, and the swing rod 504 does not rotate. At this time, the indicator light 6 is in the extinguished state; please refer to Figure 5 and Figure 6 again. As the car 3 runs to the corresponding working platform 1, when the touch plate touches the roller 505, the roller 505 is the main stress point. When the roller 505 is stressed, it drives the swing rod 504 to rotate, and the switch box 501 remains stationary, so as to realize the conversion between the contacts of the switching element in the switch box 501, thereby turning on the indicator light 6. At this time, the indicator light 6 in the car 3 lights up, achieving the purpose of indicating that the car 3 has reached the corresponding working platform 1, and then reminding the operator that the lift can be stopped.
