The first roller shaft 6 and the second roller shaft 7 can be rotated by the first motor 4 and the second motor 5, respectively.

The above-mentioned opening and closing member 8 includes a canvas 81, one end of the canvas 81 is wound around the first roller shaft 6, both sides of the other end are respectively connected with a pull rope 82 (specifically, a wire rope), and the two pull ropes 82 are wound around the second roller shaft 7. When the maintenance port is in a closed state, the canvas 31 is unfolded to cover the top of the working space 2, and the stay ropes 82 are mostly wound on the second roll shafts 7, so that the working space 2 is in a closed state, and closed ventilation collection is facilitated. When the maintenance opening is in an open state, the canvas 31 is wound on the first roll shaft 6, a small part of the pull rope 82 is wound on the second roll shaft 7, and a large part of the pull rope is positioned on two sides of the maintenance opening, at the moment, the top of the working space 2 is in an open state, so that the hoisting of parts is convenient for maintaining the machine equipment 3.

A sealing member 21 is further provided on the top of the working space 2, and the opening and closing member 8 and the sealing member 21 are in contact sealing when the opening and closing member 8 closes the maintenance opening. Specifically, the sealing member 21 is a PVC film, which is located at the top around the sidewall of the working space, is disposed below the canvas 81, and can be abutted against the bottom of the canvas 81, so as to improve the sealing effect of the working space 2, and prevent exhaust gas in the working space 2 from being discharged through the gap between the canvas 81 and the frame 1.

Further, the canvas 81 is fixedly connected with a guide rod 83 on one side close to the second roll shaft 7, two groups of guide rails 11 are arranged at the top of the frame 1, guide grooves are formed in one side, facing the canvas 81, of the two groups of guide rails, two ends of the guide rod 83 are respectively arranged in the two groups of guide grooves in a penetrating mode, when the canvas 81 is unfolded or folded, the guide rod 83 can slide along the guide grooves, and the guide grooves can play a guide role on the guide rod 83 to ensure the smoothness of the canvas 81.

The limit switch 9 is designed to determine whether the canvas 81 is deployed in place or not

And (5) collecting the materials in place.

When the maintenance port needs to be closed, the first motor 4 drives the first roll shaft 6 to rotate so as to release the canvas 81 wound on the first roll shaft, meanwhile, the second motor 5 drives the second roll shaft 7 to rotate so as to gradually wind the pull rope 82 on the second roll shaft 7, so that the canvas 81 is gradually unfolded towards the direction of the second roll shaft 7, when the guide rod 83 touches the limit switch 9 connected to the second motor 5, the limit switch 9 feeds back a signal, the controller receives the signal and then controls the first motor 4 and the second motor 5 to synchronously stop working, at the moment, the canvas 81 is abutted with the sealing piece 21, the working space 2 is sealed, and waste gas is conveniently collected in a sealed state.

Likewise, when the maintenance port needs to be opened, the first motor 4 drives the first roller shaft 7 to reversely rotate so as to gradually wind the canvas 81 on the first roller shaft 6, and simultaneously, the second motor 5 drives the second roller shaft 7 to reversely rotate so as to gradually release the pull rope 82 wound on the second roller shaft 7, thereby gradually retracting the canvas 81 towards the direction of the first roller shaft 6. When the guide rod 83 touches the limit switch 9 connected to the first motor 4, the limit switch 9 feeds back a signal, the controller receives the signal and then controls the first motor 4 and the second motor 5 to stop working synchronously, at this time, the canvas 81 is wound on the first roller shaft 6, and the stay ropes 82 are mostly positioned on two sides of the maintenance port, so that the maintenance port is opened, and parts are lifted from the maintenance port to the working space 2 conveniently.
