Description
Technical Field
A device for preventing inclined shaft construction accidents relates to a vehicle for mine inclined shaft construction, in particular to a device for preventing equipment such as skip buckets, mine cars and the like from running accidents.
Background
In the process of mine construction, inclined shaft construction is always a difficult project of mine construction engineering and is accompanied by higher danger. And arranging bumpers within 20m below a well head and within 30m above a driving working surface according to the requirements of nonferrous metal mine roadway engineering construction specifications. At present, the mode is adopted to stop the car in most in the industry, but the anti-running system also has a plurality of problems, the skip bucket needs to be suspended when running to the position every time, and the skip bucket passes through after the car stopping fence is opened manually, so that the construction efficiency is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a device for preventing the running accidents of inclined shaft construction skip buckets and mine car equipment, which has the advantages of high system reliability, capability of ensuring the safety of operating personnel, reducing the influence on lifting, convenience in operation and acceleration of construction progress.
The purpose of the utility model is realized by the following technical scheme.
The utility model provides a prevent device of inclined shaft construction accident which its structure includes:
a vehicle stopping rail frame; the fence frame is a bracket support manufactured by processing channel steel, and is arranged at the arch angle of the inclined shaft, and the upper end of the bracket support is connected with a main beam of the inclined shaft through a rotating shaft; the lower end of the hurdle frame is provided with a horizontal stiffening beam;
a flexible car stopping rope; the car stopping rope consists of foundation bolts injected on two sides of a shaft, an energy absorber and a steel wire rope, wherein the steel wire rope is wound on the middle lower part of a car stopping fence frame and is fixedly connected with the car stopping fence frame;
a barrier frame control mechanism; the mechanism comprises a control winch arranged on the inclined shaft main beam above the car stopping fence frame in the middle, a guide pulley fixed on the upper top of the inclined shaft, and a horizontal stiffening beam arranged at the lower end of the car stopping fence frame and connected with one end of the control winch through the guide pulley.
The device for preventing the construction accident of the inclined shaft is characterized in that the car stopping fence frame control mechanism is connected with a depth sensor for controlling the operation in the inclined shaft and the skip bucket and a PLC control box through signals.
The device for preventing the inclined shaft construction accident has the advantages of being simple in structure, novel in design, practical and reliable, capable of effectively intercepting the situation that the skip glides in each time, reducing the possibility of skip car running, overcoming the defect of low reliability of an original anti-running system, improving the safety of engineering construction, guaranteeing the life safety of field operation personnel, reducing the influence of the anti-running system on the inclined shaft lifting, accelerating the construction progress and obtaining good economic benefits.

Fig. 1 is a schematic structural view of a device for preventing an accident in inclined shaft construction according to the present invention.
Detailed Description
A device for preventing inclined shaft construction accidents structurally comprises:
a vehicle stopping hurdle frame 1; the fence frame is a bracket support manufactured by processing channel steel, and is arranged at the arch angle of the inclined shaft, and the upper end of the bracket support is connected with a main beam of the inclined shaft through a rotating shaft; the lower end of the hurdle frame is provided with a horizontal stiffening beam;
a flexible car stopping rope; the car stopping cable consists of foundation bolts 2 injected on two sides of a shaft, an energy absorber 3 and a steel wire rope 4, wherein the steel wire rope is wound on the middle lower part of a car stopping fence frame and is fixedly connected with the car stopping fence frame;
a barrier frame control mechanism; the mechanism comprises a control winch arranged on the inclined shaft main beam 5 above the car stopping fence frame in the middle for connection, a guide pulley 6 fixed on the upper top of the inclined shaft, and a horizontal reinforcing beam arranged at the lower end of the car stopping fence frame and connected with one end of the control winch through the guide pulley.
According to the device for preventing the inclined shaft construction accident, the car stopping fence frame control mechanism is connected with signals of the depth sensor 7 and the PLC control box 8 which are used for controlling the operation and skip bucket in the inclined shaft.
When the skip bucket is used, the PLC control box of the hoisting chamber judges the current running position and direction of the skip bucket by receiving signals sent by the hoisting sensor and the encoder. When the skip is above the slope starting point of the inclined shaft, the car stopping fences are all in a closed state; when the position of the skip bucket is judged to be 10m in front of a certain car stopping fence (the position is lifted to be 10m behind the car stopping fence, a preset lifting point can be automatically set), the master control PLC control box sends a lifting instruction to the car stopping fence control winch, the car stopping fence control winch opens the car stopping fence, and when the skip bucket moves down to 10m behind the car stopping fence (the position is lifted to be 10m in front), the master control PLC control box sends a lowering instruction to the car stopping fence control winch, and the car stopping fence control winch closes the car stopping fence.
If the winch fails and the skip running speed exceeds the maximum running speed, the PLC control box immediately sends out an alarm protection instruction; or the winch steel wire rope, the skip traction frame, the fork joint and the pin shaft are broken, the skip runs and collides with the car stopping fence (figure 1), the car stopping fence in-place sensor sends a running signal to the PLC control box, the PLC control box immediately sends an alarm protection instruction, the sensor signal fails, all the car stopping fences control the safety circuit of the winch to be disconnected, and the car stopping fence is in a closed state; if the winch operator finds the roadster through monitoring, the winch emergency stop device can be immediately pulled down, all the car stopping fences are normally closed, the signals of the sensors fail, all the car stopping fences control the winch to be in a power-off state, and the situation that the skip rushes into the inclined shaft to cause safety accidents under various conditions can be prevented.
