DETAILED DESCRIPTION

[0028] The technical solution of the present utility model is further described clearly and completely below in conjunction with the accompanying drawings.

[0029] See attached Figure 1-5 , installation and connection of the device, the base 12 is fixedly mounted on the bottom of the main support 4 by welding or bolting, and the crossbeam 8 is welded on the main support 4. The winch 1 is set on one side of the main support 4, the lower fixed pulley 3 is installed at one end of the crossbeam 8, the upper fixed pulley 5 and the positioning pulley group 7 are respectively installed on the top of the main support 4, one end of the wire rope 6 is fixedly mounted on the positioning pulley group 7, and the other end is connected to the winch 1 by passing through the lifting pulley 9, the upper fixed pulley 5 and the lower fixed pulley 3. Four anti-collision mechanisms 13 are installed on the front, back, left and right of the edge of the sealing cap 11, and the lifting pulley shaft pin 14 is installed on the lifting pulley 9. The oil cup 15 is fixedly mounted on the end of the lifting pulley shaft pin 14. The lifting pulley 9 is connected to the sealing cap 11 through a connecting rod mechanism 10.

[0030] Four guide rails 2 are fixed on the columns at the front, rear, left and right of the main bracket 4. A lower fixing seat 23 and an upper fixing seat 24 are welded respectively at the positions corresponding to the sealing cap 11 and the guide rails 2. The guide wheel 20 is installed at one end of the guide wheel connector 21 and contacts the guide rail 2. The other end of the guide wheel connector 21 is installed on the lower fixing seat 23. Both ends of the shock absorber 22 are connected to the lower fixing seat 23 and the upper fixing seat 24 respectively. After the above connection and installation are completed, four anti-collision mechanisms 13 are respectively formed at the front, rear, left and right of the edge of the sealing cap 11.

[0031] The sealing cap 11 is provided with three connecting rod mechanisms 10, and each connecting rod mechanism 10 forms an angle of 120°. The upper connecting plate 18 and the lower connecting plate 19 of the connecting rod mechanism 10 are connected to the cap connecting plate 17 by the connecting plate shaft pin 16, and the other end of the cap connecting plate 17 is fixedly mounted on the sealing cap 11.

[0032] When in use, after the winch 1 starts working, the rotating turntable on the winch 1 tightens the wire rope 6. Since one end of the wire rope 6 is fixedly mounted on the positioning pulley block 7, when the wire rope 6 is tightened around the upper fixed pulley 5 and the lower fixed pulley 3, the lifting pulley 9 is lifted upward. While the lifting pulley 9 is lifted upward, the lifting pulley 9 drives the connecting rod mechanism 10 to move upward, and the connecting rod mechanism 10 drives the sealing cap 11 to start moving upward. At the same time, the guide wheel 20 installed at the end of the guide wheel connector 21 moves upward along the guide rail 2, and the sealing cap 11 opens. When the lifting pulley 9 moves to the top of the main support 4, the sealing cap 11 reaches the maximum opening position, and the winch 1 stops. The anti-collision mechanism 13 is adjusted to the optimal position, and the guide wheel 20, the guide rail 2, and the shock absorber 22 cooperate with each other to ensure the smooth movement and position stability of the sealing cap 11, and further strengthen the sealing performance between the sealing cap 11 and the base 12.

[0033] The winch 1 rotates in the opposite direction, the wire rope 6 goes around the upper fixed pulley 5 and the lower fixed pulley 3 and starts to relax, the lifting pulley 9 moves downward, the lifting pulley 9 drives the connecting rod mechanism 10 to move downward, the connecting rod mechanism 10 drives the sealing cap 11 to move downward, and at the same time, the guide wheel 20 installed at the end of the guide wheel connector 21 moves downward along the guide rail 2. When the sealing cap 11 is at the lowest position and the guide wheel 20 moves downward along the guide rail 2 to return to the initial position, the sealing cap 11 is completely closed and the winch 1 stops.

[0034] During the opening and closing process, the winch 1 can be suspended at any position of the travel at any time to adjust the size of the opening or closing gap of the sealing cap 11, and select the appropriate opening or closing degree of the sealing cap 11 according to needs.

[0035] The oil cup 15 is installed on the reserved hole of the lifting pulley pin 14 to oil the lifting pulley 9 so that the lifting pulley 9 can rotate on the lifting pulley pin 14 more smoothly.

[0036] The above is only a non-limiting implementation method of the utility model, and a large number of embodiments can be derived. For ordinary technicians in this field, without departing from the creative concept of the present invention and without making creative work, several modified and improved embodiments can be made, which all fall within the scope of protection of the present invention.
