DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] See also Figure 1 The utility model provides a technical solution: a sling for a pressure vessel cover, comprising a lower connecting block 1 arranged on a pressure vessel cover plate and a mounting plate arranged on one side of the pressure vessel, the pressure vessel cover plate being arranged at the bottom of the pressure vessel, and the pressure vessel cover plate can be opened and closed up and down, an upper connecting block 2 is arranged on the lower connecting block 1, a screw rod 3 is rotatably mounted on the upper connecting block 2, a wrench 5 is arranged on one side of the top of the screw rod 3, a nut sleeve 4 is threadedly sleeved on the screw rod 3; a vertical shaft support 11 is arranged on the vertical shaft support 11, a bearing sleeve 9 is arranged, a vertical shaft 8 is rotatably inserted at the axis of the bearing sleeve 9, a vertical shaft upper cover 7 is sleeved on the top of the vertical shaft 8, a rotating arm crossbeam 6 is arranged on one side of the vertical shaft upper cover 7, and an end of the rotating arm crossbeam 6 away from the vertical shaft upper cover 7 is fixedly connected to the nut sleeve 4; pulling the wrench 5 can drive the screw rod 3 to rotate on the upper connecting block 2, and during the rotation of the screw rod 3, the screw rod 3 will move up and down along the nut sleeve 4, thereby driving the container cover to be lifted (opened) or lowered (covered).

[0017] When the container cover needs to be opened, the screw rod 3 is pushed clockwise by the wrench 5. When the screw rod 3 rotates clockwise, the screw rod 3 will move upward along the nut sleeve 4. At the same time, the screw rod 3 drives the container cover to move upward through the upper connecting block 2 and the lower connecting block 1, so that the container cover and the pressure vessel are separated. Then, the container cover is pushed to make the arm crossbeam 6 and the vertical shaft 8 rotate around the bearing sleeve 9 together, so that the container cover and the pressure vessel are misaligned, so that the pressure vessel is opened; when the container cover needs to be closed on the pressure vessel, When the pressure vessel is on the upper surface, the container cover is pushed in the opposite direction to make the arm crossbeam 6 and the vertical shaft 8 rotate around the bearing sleeve 9 together, so that the container cover is shifted to the top of the pressure vessel, and then the screw rod 3 is pushed counterclockwise by the wrench 5. When the screw rod 3 rotates counterclockwise, the screw rod 3 will move downward along the nut sleeve 4. At the same time, the screw rod 3 pushes the container cover downward through the upper connecting block 2 and the lower connecting block 1, so that the container cover is closed on the pressure vessel. The hanging column can open the heavier pressure vessel cover by manpower, which is easy to operate and saves effort.

[0018] Among them, an oil filling hole is opened on one side of the bearing sleeve 9, and lubricating oil can be injected into the bearing cavity of the bearing sleeve 9 through the oil filling hole to play a lubricating role and ensure that the vertical shaft 8 can rotate flexibly relative to the bearing sleeve 9.

[0019] Among them, a rain cover plate 10 is provided on one side of the top of the bearing sleeve 9 around the vertical shaft 8, the rain cover plate 10 blocks the opening at the top of the bearing sleeve 9, and an insertion hole matching the vertical shaft 8 is opened at the axis of the rain cover plate 10, the vertical shaft 8 passes through the rain cover plate 10 through the insertion hole, and the outer wall of the vertical shaft 8 does not contact the inner wall of the insertion hole, the rain cover plate 10 blocks the top of the bearing sleeve 9, and the rain cover plate 10 does not affect the rotation of the vertical shaft 8. The rain cover plate 10 is used to block rain or dust from entering the bearing sleeve 9.

[0020] Among them, the vertical shaft support 11 and the mounting plate are vertically arranged, and a reinforcing rib 12 is provided at the angle between the vertical shaft support 11 and the mounting plate. The reinforcing rib 12 strengthens the connection strength between the vertical shaft support 11 and the mounting plate to prevent the vertical shaft support 11 from tilting relative to the mounting plate.

[0021] Among them, a shaft sleeve is embedded in the center of the upper surface of the upper connecting block 2, and a smooth end matching with the shaft sleeve is provided at the bottom of the screw rod 3. The screw rod 3 is rotatably installed on the upper connecting block 2 through the smooth end matching with the shaft sleeve.

[0022] Working principle: When in use, when it is necessary to open the container cover, the screw rod 3 is pushed clockwise by the wrench 5. When the screw rod 3 rotates clockwise, the screw rod 3 will move upward along the nut sleeve 4. At the same time, the screw rod 3 drives the container cover to move upward through the upper connecting block 2 and the lower connecting block 1, thereby separating the container cover from the pressure vessel, and then pushing the container cover to make the arm crossbeam 6 and the vertical shaft 8 rotate around the bearing sleeve 9 together, so that the container cover and the pressure vessel are misaligned, thereby opening the pressure vessel; when it is necessary to cover the container cover, When it is closed on the pressure vessel, push the container cover in the opposite direction to make the arm crossbeam 6 and the vertical shaft 8 rotate around the bearing sleeve 9 together, so that the container cover is shifted to the top of the pressure vessel, and then push the screw rod 3 to rotate counterclockwise through the wrench 5. When the screw rod 3 rotates counterclockwise, the screw rod 3 will move downward along the nut sleeve 4. At the same time, the screw rod 3 pushes the container cover downward through the upper connecting block 2 and the lower connecting block 1, so that the container cover is closed on the pressure vessel. The hanging column can use manpower to open the heavier pressure vessel cover, which is easy to operate and saves effort.

[0023] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
