DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 of the embodiments.

[0021] Reference Figure 1-4 A mine cage electric rolling door device comprises a cage body 1, a plurality of equally spaced curtain rods 2 are arranged on one side of the cage door of the cage body 1, a motor 3 is fixedly arranged on the top of the cage body 1, a winding disk 4 is fixedly arranged on the output end of the motor 3, a rope 5 is wound around the winding disk 4, the bottom end of the rope 5 passes through a plurality of curtain rods 2 and is fixed to the lowest curtain rod 2, and a through hole 11 for the rope 5 to pass through is opened on the plurality of curtain rods 2.

[0022] Specifically, when the rolling door of the cage body 1 needs to be opened, the motor 3 drives the winding disc 4 to rotate, and then drives the winding disc 4 to reel in the rope 5. The rope 5 moves upward and drives the bottom curtain rod 2 to move upward. During the upward movement of the bottom curtain rod 2, it will sequentially drive multiple curtain rods 2 at the top to move upward, and finally make the multiple curtain rods 2 gather at the top, thereby opening the rolling door.

[0023] In addition, a second slide bar 16 is fixedly provided on one side of the tank door of the tank cage body 1, and a plurality of curtain rods 2 are provided with round holes 17 that are slidably matched with the second slide bar 16, and the second slide bar 16 is used for limiting the position.

[0024] Furthermore, a support assembly is provided between the multiple curtain rods 2, and the support assembly includes a first connecting rod 6 and a second connecting rod 7 which are hingedly arranged. A mounting groove 8 is opened on the multiple curtain rods 2, and a first sliding rod 9 is fixedly arranged in the multiple mounting grooves 8. Two sliding blocks 10 are slidably arranged on the multiple first sliding rods 9, and the two ends of the first connecting rod 6 are respectively hinged to the two sliding blocks 10, and the two ends of the second connecting rod 7 are respectively hinged to the two sliding blocks 10.

[0025] A movable groove 12 is provided at the middle of the first connecting rod 6 , and the second connecting rod 7 is inserted into the movable groove 12 .

[0026] Specifically, by means of the hinged first connecting rod 6 and the second connecting rod 7, the intervals between the multiple curtain rods 2 are blocked to avoid safety hazards as much as possible. During the opening process of the rolling door, the lower curtain rod 2 moves upward and drives the first connecting rod 6 and the second connecting rod 7 to rotate. At the same time, the two sliders 10 at both ends slide to both sides along the first sliding rod 9, thereby folding and tightening the first connecting rod 6 and the second connecting rod 7.

[0027] In addition, a controller 14 is fixedly arranged on the top of the cage body 1, and a control panel 15 is fixedly arranged on the inner wall of the cage body 1. The control panel 15 and the motor 3 are electrically connected to the controller 14 through wires.

[0028] In addition, the surfaces of the first connecting rod 6, the second connecting rod 7 and the first sliding rod 9 are coated with anti-rust oil to improve the anti-rust effect.

[0029] Finally, four lifting rings 13 are fixedly arranged on the top of the cage body 1 , and the four lifting rings 13 are respectively arranged at the four corners of the top of the cage body 1 .

[0030] The operating principle of the utility model is now described as follows: the cage body 1 is lifted to the ground or dropped to the bottom platform of the well, and the intervals between the multiple curtain rods 2 are blocked by the hinged first connecting rod 6 and the second connecting rod 7 to avoid safety hazards as much as possible. The hooker presses the button of the control panel 15, and the motor 3 is controlled to start by the controller 14. The motor 3 drives the winding drum 4 to rotate, and then drives the winding drum 4 to reel in the rope 5. The rope 5 moves upward and drives the bottom curtain rod 2 to move upward. During the upward movement of the bottom curtain rod 2, it will successively drive the upper multiple curtain rods 2 to move upward, and finally make the multiple curtain rods 2 converge at the top, and then open the rolling door to allow personnel and equipment to enter and exit. During the opening process of the rolling door, the lower curtain rod 2 moves upward and drives the first connecting rod 6 and the second connecting rod 7 to rotate. At the same time, the two sliders 10 at both ends slide to both sides along the first slide bar 9, so that the first connecting rod 6 and the second connecting rod 7 are folded and tightened.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
