[0007] The utility model discloses an electric rolling door device for a mine pit waiting tank area, comprising a guide rod installed on the tank cage door, the guide rods are respectively fixed on the inner wall of the tank cage door, a plurality of sliding matching blocking rods are installed on the guide rods, a connecting chain is connected between the blocking rods, a pulling rope is installed between the blocking rods, wherein the pulling rope is fixed on the blocking rod at the bottom, and the pulling rope is movably connected to the other blocking rods; a driving mechanism for tightening the pulling rope is installed at the top of the tank cage;

[0008] The driving mechanism comprises a fixing frame fixed at the uppermost end of the cage, a rotatable winding drum is installed on the fixing frame, and a motor for driving the winding drum is installed at one end of the fixing frame.

[0009] Furthermore, a positioning rod is fixed to the upper end of the guide rod, and a guide wheel group is installed on the positioning rod.

[0010] Furthermore, the guide wheel assembly includes two guide wheels used in conjunction with each other, and a pulling rope is passed through the space between the two guide wheels.

[0011] Furthermore, at least two connecting chains are installed.

[0012] Furthermore, two pulling ropes are installed, and the pulling ropes are installed on both sides of the barrier rod.

[0013] Furthermore, a stopper is installed at the lower end of the pulling rope.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model uses a driving mechanism to pull up the barrier rod with a pulling rope to realize the automatic opening and closing function, which can reduce the operation time of personnel and improve production efficiency. In addition, the barrier rods of the device are connected with a connecting chain, so that the overall structure is simple, the installation is convenient, and the use is safe and reliable, which can effectively ensure the safe transportation of personnel and materials.

[0021] Example 1

[0022] like Figure 1 to Figure 3 As shown, the electric rolling shutter door device for the mine wellhead waiting area described in the utility model includes a guide rod 8 installed on the door of the tank cage 1, the guide rod 8 is respectively fixed on the inner wall of the door of the tank cage 1, and a plurality of slidingly matched blocking rods 6 are installed on the guide rod 8, and connecting chains 7 are connected between the blocking rods 6, and the connecting chains 7 are welded and fixed on the blocking rods 6, and pulling ropes 3 are installed between the blocking rods 6, wherein the pulling ropes 3 are fixed on the blocking rods 6 at the lower end, and the pulling ropes 3 and the other blocking rods 6 are movably connected; a driving mechanism 2 for tightening the pulling rope 3 is installed at the uppermost end of the tank cage 1; the pulling rope 3 is a soft rope, which is convenient for the winding drum 23 to be wound up.

[0023] The driving mechanism 2 comprises a fixing frame 22 fixed to the uppermost end of the cage 1, a rotatable winding drum 23 is mounted on the fixing frame 22, and a motor 21 for driving the winding drum 23 is mounted at one end of the fixing frame 22; the motor 21 may be a servo motor.

[0024] A positioning rod 5 is fixed to the upper end of the guide rod 8 , and a guide wheel group 4 is installed on the positioning rod 5 to ensure that the pulling rope 3 is pulled vertically when the blocking rod 6 is pulled.

[0025] The guide wheel assembly 4 includes two guide wheels 41 used in conjunction with each other, and the pulling rope 3 is passed through the space between the two guide wheels 41 .

[0026] At least two connecting chains 7 are installed, and two, three, four, or five can be fixed accordingly.

[0027] Two pulling ropes 3 are installed, and the pulling ropes 3 are installed on both sides of the blocking rod 6, so that the blocking rod 6 is subjected to more uniform force during the pulling process.

[0028] A stopper 9 is installed at the lower end of the pulling rope 3 for lifting the lowermost stopper rod 6 . The stopper 9 can be directly fixed to the end of the pulling rope 3 to prevent the pulling rope 3 from slipping out of the hole of the stopper rod 6 .

[0029] Working process or working principle:

[0030] The operating button inside the cage 1 is operated to make the motor 21 rotate forward, and the motor 21 drives the winding drum 23 to rotate. The winding drum 23 tightens the pulling rope 3, and the pulling rope 3 pulls up the blocking rod 6 layer by layer from bottom to top; when the blocking rod 6 is lowered, the operating button installed on the outer wall of the cage 1 is operated, the motor 21 is reversed, and the blocking rod 6 is lowered.
