[0057] The load limiter is electrically connected to the winch 310, and the permissible overload value of the winch 310 is generally set to not be greater than 10% of the rated lifting capacity. Therefore, when the actual load reaches 110% of the rated lifting capacity, the load limiter should automatically cut off the power supply of the winch 310, causing the winch 310 to stop rotating.

[0058] The stroke limiter is electrically connected to the winch 310 and is disposed at the upper and lower ends of the slide rail 200. A stroke switch controller is generally used. When the winch 310 is lifted or lowered beyond a specified value, the stroke switch controller will automatically cut off the power supply of the winch 310, causing the winch 310 to stop rotating.

The main functions of the depth indicator are to indicate the actual position of the hanging basket 100 in the shaft 10, to send out deceleration and overwinding signals, and to perform overspeed protection during the constant speed lifting process. When the indicator fails, it should be able to automatically cut off the power and make the safety gate work.

[0060] The overspeed prevention device is installed on the hanging basket 100. When the lifting speed exceeds the maximum speed by 15%, the overspeed prevention device should be able to automatically cut off the power and enable the safety gate to brake.

[0061] The slack rope protector is arranged on the hoist 310, and the hoist 310 should connect the slack rope protector to the alarm circuit and / or the safety circuit. The slack rope protector is used for the hoist 310 to automatically cut off the power and alarm when the lifting main rope 340 is loose.

[0062] The indicator light alarm assembly includes an alarm indicator light and an alarm switch, the alarm indicator light and the alarm switch are electrically connected, the alarm indicator light is arranged at the wellhead of the shaft 10, and the alarm switch is arranged at the construction working surface of the shaft 10. When an abnormality occurs in the underground operation, the staff can activate the alarm indicator light through the alarm switch and notify the upper management personnel in time.

[0063] In an optional embodiment, the shaft lifting device further comprises a controller, and the hoist 310, the winch 410, and the safety protection mechanism are all electrically connected to the controller. By setting up the controller, the staff can conveniently control various functions of the shaft lifting device.

[0064] The shaft lifting device described in the embodiment of the present application has the following beneficial effects:

[0065] 1. By arranging the guide anti-falling mechanism 400 on both sides of the slide rail 200, the two sides of the hanging basket 100 can be movably connected to the guide anti-falling mechanism 400. The guide anti-falling mechanism 400 can provide guidance and anti-falling effects on the hanging basket 100, and limit the movement of the hanging basket 100 along the direction of the slide rail 200, thereby avoiding the derailment of the hanging basket 100. In addition, when the main lifting rope 340 breaks, the hanging basket 100 can be prevented from falling, thereby reducing the safety hazards in the construction process, and has the advantage of high safety.

[0066] 2.
