The handle 20 is fixed to both ends of the cover plate 12, the support plate 23 is fixed to the top surface of the groove 21, and the second Z-shaped through hole 24 is opened on the support plate 23.

[0034] The second Z-shaped through hole 24 is the same size as the first Z-shaped through hole 22 , and the connecting shaft 25 is inserted into the second Z-shaped through hole 24 ;

[0035] The handle 20 facilitates pulling the cover 12, the groove 21 is used to install the wheel 26, the support plate 23 plays a supporting role, the first Z-shaped through hole 22 and the second Z-shaped through hole 24 play an adjusting role, the connecting shaft 25 plays a connecting and supporting role, and the wheel 26 facilitates the movement of the cover 12.

[0036] Working principle:

[0037] First, one person lifts up the handle 20 at one end of the cover plate 12, and the other person pulls the connecting shaft 25 to move it downward along the first Z-shaped through hole 22 and the second Z-shaped through hole 24 to the lowest port, and puts down the cover plate 12. According to the above operation, move the connecting shaft 25 at the other end of the cover plate 12 down, and then put down the cover plate 12. At this time, the wheel 26 lifts the cover plate 12, pulls the handle 20 on the inclined side of the wellhead 11, and pulls the cover plate 12 onto the platform 10. As the cover plate 12 moves, the wheel 26 is driven to rotate and move in accordance with the wellhead 11 and the platform 10. After the maintenance is completed, push the cover plate 12 in the opposite direction to the wellhead 11, and according to the above operation, move the connecting shaft 25 to the uppermost port of the first Z-shaped through hole 22, so that the cover plate 12 falls and fits with the wellhead 11.

[0038] In this step, the cover 12 can be opened quickly without the aid of external equipment, thereby improving maintenance efficiency.

[0042] The protection assembly further includes a baffle 33 , which is fixed to one end of the inner side of the protection cover 32 ;

[0043] The clamping slot 30 plays a connecting and limiting role, the locking rod 31 plays a fastening role, the protective cover 32 plays a protective role, the baffle 33 plays a limiting role, and the clamping block 34 plays a connecting role.

[0044] Working principle:

[0045] Before removing the cover 12, first loosen the locking rod 31, push the protective cover 32 upward along the card slot 30, drive the card block 34 to move upward, so that the first Z-shaped through hole 22 is exposed, and then move the connecting shaft 25 to the lower end of the first Z-shaped through hole 22, and lower the protective cover 32. At this time, the connecting shaft 25 is located on the side with a smaller gap between the baffle 33 inside the protective cover 32. After the inspection is completed, pull the protective cover 32 upward, move the connecting shaft 25 to the upper end of the first Z-shaped through hole 22, and close the protective cover 32.

[0046] This step can, on the one hand, seal the first Z-shaped through hole 22 to reduce the amount of harmful gas overflowing, and on the other hand, prevent the connecting shaft 25 from moving back and forth when the cover plate 12 moves.
