Description

Technical Field

[0001] The utility model relates to a monorail type manned vehicle capable of vertically lifting, belonging to the technical field of industrial manned vehicles. Background Art

[0002] Riser pipes on exploration vessels are crucial underwater equipment components. These steel pipes connect the subsea blowout preventer assembly and the floating offshore drilling rig. They primarily serve to isolate seawater, guide drill tools and casing, and form a channel for mud circulation. Multiple risers of the same length, capable of withstanding high pressures, are installed in combination for kill or blowout lines. The total length is determined by the operating water depth. These risers are arranged in multiple layers vertically to minimize floor space. Each riser operation requires specialized personnel to remove and attach lifting gear. However, since the vessel's built-in lifting equipment is located at the edge of the hull, its reach is limited, creating significant operational difficulties and inefficient operations.

When the horizontal driving device 7 is started, the guide rail frame 2 drives the manned frame 6 to move horizontally. At the same time, the lifting device 5 can enable the manned frame 6 to move up and down along the guide rail frame 2, thereby enabling the operator to lift up and down and move left and right in a narrow space, thereby improving work efficiency.

[0023] The lifting device 5 includes a double drum connected to a drive motor. The drum has a left-handed and right-handed rope groove. Wire ropes of different rotation directions pass around wire rope guide wheels 1 at different positions and connect to the top or bottom of the corresponding manned frame 6. The motor drives the drum to rotate. Because the left-handed and right-handed rope grooves are used, the wire ropes passing around the upper and lower wire rope guide wheels 1 can simultaneously drive the manned frame 6 up and down in the same direction.

A rack 73 is provided at a corresponding position on the lower guide rail 9, and the gear 72 meshes with the rack 73. The meshing of the gear and rack not only enables slight movement, but also achieves a locking effect by meshing and locking the rack and gear when the guide rail is not moving.

[0025] like Figure 6As shown, the back of the passenger frame 6 is equipped with vertical guide wheels 61; vertical guide beams 63 are fixedly mounted on the front, left, and right surfaces of the guide rail frame 2. The vertical guide wheels 61 are arranged in groups and positioned on either side of the guide beams 63 at corresponding positions. Horizontal guide wheels 62 are also mounted on the back of the guide rail frame 2. Vertical limit plates 64 are provided near the ends of the upper guide rail 4 near the guide rail frame 2. The groups of horizontal guide wheels 62 slide against the front and rear ends of the limit plates 64. The vertical and horizontal movement of the passenger frame and the left and right movement of the guide rail frame 2 are both limited by the guide wheels, ensuring safe operation of the equipment even in unstable external environments.

[0026] The side ends of the guide rail frame 2 support the drag chain 3 through the support frame, and the bottom of the drag chain 3 is connected to the lower end of the manned frame 6; the driving power line and the control line are located inside the drag chain 3. Prevent extreme weather or working conditions to ensure safe electrical operation.

[0027] like Figure 5 As shown, the bottom surface of the manned frame 6 is divided into a front bottom surface and a rear bottom surface, which are connected by a rotating shaft. A folding cylinder 65 is provided at the bottom of the manned frame 6, and the piston rod of the folding cylinder 65 is connected to the ear piece provided on the front bottom surface; when the fence of the manned frame 6 is flipped upward at the front bottom surface, the fence is also in a folded state.
