When the top door opening 611 needs to be closed, the closing button is activated, and at this time, the switch push rod 4 starts to retract, so as to drive the guide frame 1 and the sealing cover 2 to perform linear movement towards the second end of the cabin. Because the wheel groove 221 is formed in the cabin roof 61, as shown in fig. 8, before the top door opening is completely closed, in the rolling and advancing process of the supporting wheel 22 on the horizontal plane of the cabin roof 61, the two compression bar shaped shafts 53 swinging to the highest position can enter the two top cover pressing seats 23 successively, and the upward jacking force is applied to the top cover pressing seats 23 to enable the sealing cover to be still at the upper end, so that the whole sealing cover cannot descend, and the phenomenon that the individual supporting wheel collides with the edge of the wheel groove when suspended through the wheel groove can be prevented, so that the supporting wheel jolts in the advancing process, and the running balance is affected. The end of the compression bar special-shaped shaft 53 is provided with a roller, the sealing cover 2 continuously moves, the roller rolls on the inner contact surface of the top cover pressing seat 23, when the top cover pressing seat 23 is supported, the compression bar special-shaped shaft 53 and the inner end surface of the top cover pressing seat are relatively stressed, the roller is designed, equipment damage caused when the sealing cover continuously moves under the condition is avoided, the supporting wheel 22 is ensured to cross the wheel groove, and the operation on the horizontal surface of the cabin top plate 61 is continued until the sealing cover 2 completely moves to the position right above the top door opening. At this time, the switch push rod 4 is contracted to the shortest position, the push rod 3 is pressed down to the longest state, and the two press rod shaped shafts 53 are just positioned in the two top cover pressing seats 23, so that the whole sealing cover 2 is positioned at the upper end, namely in the jacked state, and the lower parts of all the supporting wheels are opposite to the wheel grooves.
Then, the push rod 3 starts to shrink until the shortest position, the two compression bar profiled shafts 53 swing synchronously to the lowest position, and simultaneously, downward pressure is applied to the top cover pressing seat 23, at this time, as shown in fig. 9, all the supporting wheels 22 fall into the corresponding wheel grooves 221 below the push rod, the switch push rod 4 shrunk to the shortest state floats downwards synchronously with the pressing of the sealing cover, the sealing cover 2 contacts with the sealing strip 66 at the top door opening 611, and the compression sealing of the top door opening is completed.
In the embodiment of the invention, the side door is also provided with the electronic lock, the side door electronic lock bolt is arranged on the side door, the electronic lock body is arranged on the cabin body, after the side door is closed to enable the electronic lock bolt to be inserted into the electronic lock body, an inserted in-place signal can be transmitted to the controller PLC, the PLC can input a locking signal, the electronic lock executes a locking action, and the side door is prevented from being opened by people in a misoperation in the working process. The closing button is actuated to perform a closing action only if the side door is in an open condition, i.e., the electronic lock does not detect an "inserted" in place signal.
When the top door opening needs to be opened, firstly, whether the side door is in an open state is also required to be detected, when the side door is in the open state, namely, the electronic lock does not detect an inserted in-place signal, the opening button is started, firstly, the push rod 3 is pushed down to start stretching, the press rod special-shaped shaft 53 swings to the highest position from the lowest position, the top cover pressing seat 23 is lifted up, the sealing cover 2 is driven to start lifting, and each supporting wheel 22 is pulled out from the wheel groove and positioned right above the wheel groove, as shown in fig. 10. Then, the switch push rod 4 starts to stretch, the supporting wheel 22 starts to roll towards the first end of the cabin after crossing the wheel groove, and the guide frame 1 and the sealing cover 2 are driven to synchronously move, so that the top door opening is opened.
The above examples are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall within the scope of protection defined by the claims of the present invention without departing from the spirit of the present invention.
