Description

Technical Field

[0001] The utility model relates to the field of mine safety, in particular to a personnel safety detection device for an inclined shaft rail transportation system. Background Art

[0002] With the increasing mechanization of coal mines, underground rail transportation systems have gradually been electrified. This has led to an increase in accidents caused by electromechanical equipment failures and improper operation. Currently, inclined rail transportation systems primarily consist of tracks within the shaft (main roadway) and branch roadways connected to the shaft, as well as mine cars operating on these tracks. The primary task of the mine cars is to transport materials from underground to the surface, and from the surface to the working surfaces within the branch roadways. Mine cars are typically pulled by a winch. After traveling through the shaft to a branch roadway, materials are loaded and unloaded. Once loading and unloading is complete, personnel at the loading and unloading site enter a safe area and signal the winch operator, who activates the winch to pull the car through the switch between the shaft and branch roadway, into the shaft, and then tow the car to the surface or to the next branch roadway for loading and unloading.

[0003] Many inclined shafts in coal mines are used by both people and vehicles, transporting both materials and pedestrians. This poses safety risks and leads to frequent casualties, negatively impacting coal mine safety. This is primarily due to the inadequate protection of the winch systems in older inclined shafts, including a lack of locking controls and, in particular, a lack of human-machine safety protection, which endangers personnel. If a vehicle breaks loose, there are no remedial measures, leading to the escalation of the accident. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a personnel safety detection device for an inclined shaft rail transportation system.

[0005] In order to solve the above problems, the technical solution of the utility model is: a personnel safety detection device for an inclined shaft rail transportation system, comprising an inclined shaft and a branch tunnel connected to the inclined shaft, safety doors are provided at both ends of the inclined shaft and at the connection between the branch tunnel and the inclined shaft, a real-name channel is provided on one side outside the safety door, and high-definition infrared probes are also installed at both ends of the inclined shaft, a safety room is provided on the other side outside the safety door, and a display screen, a control console and an alarm light are provided in the safety room.

[0006] Furthermore, a plurality of car baffles are installed at equal intervals inside the inclined shaft, positioning columns are fixed to the tops of both sides of the inclined shaft, an electric winch is installed on the top, the top of the car baffle is rotatably installed on the positioning columns, a steel wire rope is wound on the electric winch, and the steel wire rope is connected to the car baffle.

[0007] Furthermore, an infrared personnel sensor is installed inside the inclined shaft between the two vehicle baffles.

[0008] Furthermore, infrared detection light curtains are installed on the inner side of the safety doors at both ends of the inclined shaft and the branch tunnel.

[0009] The advantages of the present invention over existing technologies are as follows: the present invention can prevent personnel from entering the inclined shaft during operation by setting up a safety door; the real-name system channel can be used in conjunction with an infrared detection light curtain to monitor personnel entering and exiting the inclined shaft; the infrared detection light curtain and infrared personnel sensor can detect personnel in the inclined shaft; after the mine car passes through a baffle, the baffle automatically closes, and then when the mine car runs out of control, the baffle can block the mine car, making it safer. The present invention can ensure the safety of personnel in the inclined shaft of coal mines, and respond promptly to the situation of mine car out of control, avoid the escalation of accidents after the mine car out of control, and reduce losses. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural diagram of the present utility model.

[0011] As shown in the figure: 1. Inclined shaft; 2. Branch tunnel; 3. Safety door; 4. Real-name channel; 5. High-definition infrared probe; 6. Safety room; 7. Display screen; 8. Control console; 9. Warning light; 10. Vehicle barrier; 11. Electric winch; 12. Infrared personnel sensor; 13. Infrared detection light curtain. DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0013] like Figure 1 As shown, a personnel safety detection device for an inclined shaft rail transportation system includes an inclined shaft 1 and a branch tunnel 2 connected to the inclined shaft 1, safety doors 3 are provided at both ends of the inclined shaft 1 and at the connection between the branch tunnel 2 and the inclined shaft 1, infrared detection light curtains 13 are installed on the inner side of the safety door 3 at both ends of the inclined shaft 1 and the branch tunnel 2, a real-name channel 4 is provided on the outer side of the safety door 3, and high-definition infrared probes 5 are also installed at both ends of the inclined shaft 1, a safety room 6 is provided on the other side of the outside of the safety door 3, and a display screen 7, a control console 8 and an alarm light 9 are provided in the safety room 6.

[0014] Multiple car baffles 10 are installed at equal intervals inside the inclined shaft 1. Positioning columns are fixed to the top of both sides of the inclined shaft 1, and an electric winch 11 is installed on the top. The top of the car baffle 10 is rotatably installed on the positioning columns. A steel wire rope is wound around the electric winch 11, and the steel wire rope is connected to the car baffle 10. An infrared personnel sensor 12 is installed between the two car baffles 10 inside the inclined shaft 1.

[0015] In actual use, when personnel enter and exit the inclined shaft 1, they need to pass through the real-name channel 4 to facilitate verification of personnel entry and exit. The infrared detection light curtain 13 can monitor the number of personnel entering and exiting the inclined shaft 1. When the number does not match the number passing through the real-name channel 4, the alarm light 9 will sound, making it convenient for staff to check the situation in time, take measures, and reduce the occurrence of accidents.

[0016] To implement the human-centered safety philosophy of "no pedestrians, no vehicles; no pedestrians, no vehicles," safety gates 3 are installed at both ends of inclined shaft 1 and in branch lane 2. When the mine car is in motion, pedestrian safety gates 3 remain closed, preventing entry during operation. If a person is inside inclined shaft 1 while the mine car is stopped, the car cannot start. When the mine car is operating normally, safety gates 3 cannot be opened, ensuring pedestrian safety.

[0017] Before the mine car passes normally, the baffle 10 is in the open state. After the mine car passes through a baffle 10, the baffle 10 automatically closes. Then, when the mine car is out of control, the baffle 10 can block the mine car to prevent it from running away, which is safer. During the operation of the mine car, if anyone enters the inclined shaft 1, the infrared detection light curtain 13 and the infrared personnel sensor 12 can detect the person in the inclined shaft 1 and feed back to the console 8. The console controls the alarm light 9 to sound an alarm and controls the mine car to slow down and stop.

[0018] The undisclosed parts in the present invention are all prior art, and their specific structures and working principles are not described in detail here.
