Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine intelligent ventilation, in particular to a reciprocating swinging shutter. Background Art
[0002] Mine-use adjustable air windows are an essential and important infrastructure in the ventilation system of coal mines. Their function is to adjust and control the underground ventilation flow and wind direction, and they play a vital role in providing services for underground workers and removing harmful gases from underground. With the advancement of science and technology, fully automatic adjustable louver air windows can automatically adjust the opening range of the blades, with high precision and high speed, saving human resources and improving the safety of mine ventilation. However, during use, if the staff mistakenly operates in the opposite direction, or if the switch is in place and the pressure is continuously applied, the blade switch will be over-limited. Even if the mechanical hard limit is added, the blade will no longer be over-limited, but under continuous torque, it is still easy to cause the mechanical spindle to break and the air window to be damaged, affecting its use.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0018] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0019] Figure 1-Figure 3 This is a specific embodiment of the utility model, which is a reciprocating swaying louver. A driving mechanism and a connecting rod mechanism 6 connected to the driving mechanism are arranged in the control box 1. A louver frame 2 fixed at the tunnel section is arranged on one side of the control box 1. Two upper and lower blades 201 are arranged in the louver frame 2. The two blades 201 realize reciprocating synchronous motion through the connecting rod mechanism 6. An inspection port is opened on the control box 1, and the inspection port corresponds to the internal pneumatic motor 3. A motor cover 101 is detachably connected to the inspection port. The driving mechanism includes an air motor 3, and a reducer 4 is connected to the bottom of the air motor 3 in a transmission manner. A pointer 401 is connected to one output shaft end of the reducer 4, and the other output shaft is connected to the connecting rod mechanism 6 in a transmission manner. An encoder 5 is connected to the bottom of the reducer 4 through an encoder bracket 501. The connecting rod mechanism 6 includes a coupling sleeve 601 which is transmission-connected to the output shaft of the reducer 4, one end of the coupling sleeve 601 is fixedly connected to the first short rocker arm 602, one end of the first short rocker arm 602 is hinged to one end of the first connecting rod 603, the other end of the first connecting rod 603 is hinged to the lower end of the second connecting rod 604 and the second short rocker arm 605, the upper end of the second connecting rod 604 is hinged to the third short rocker arm 606, the second short rocker arm 605 is fixedly connected to the rotating shaft of the blade 201 below, and the third short rocker arm 606 is fixedly connected to the rotating shaft of the blade 201 above.
[0020] The transmission mechanism of this embodiment is connected to the mine air network system, and can adjust the opening and closing amplitude of the blade 201 in real time according to the environment. When the pneumatic motor 3 is ventilated, it drives the reducer 4 to rotate, drives the connecting rod mechanism 6 to operate, and then drives the blade 201 to rotate. After the blade 201 rotates 90°, the wind window is fully opened. If ventilation continues, the blade 201 will rotate 90° in the opposite direction, and the wind window will be fully closed. The connecting rod mechanism of this embodiment can realize continuous ventilation of the pneumatic motor 3, the second connecting rod 604 moves up and down, and the blade only swings back and forth within 90°, thereby realizing the opening and closing of the wind window at full opening.
