AI Technical Summary
The existing steel pipe column lifting equipment cannot set up temporary supports under the bridge, and the construction is difficult due to the limitations of bridge deck construction and the clearance under the bridge.
A confined space steel pipe column lifting device is designed, which includes a support frame and a lifting device. The support frame has a lifting slot opened in the vertical direction. The column can pass through the slot and be lifted and lowered by the lifting device. The column can be detached and its stability is limited by clamps and hand hoists. Auxiliary components such as support plates and lifting units are used to facilitate the assembly of the column.
The convenient assembly of multiple columns under the bridge avoids restrictions on bridge deck construction and bridge bottom clearance, achieving stable and efficient assembly of temporary supports.

Abstract
Claims
1. A confined space steel pipe column lifting device for assembling multi-section columns, characterized in that: It includes a support frame (1) and a lifting device (2). A lifting groove (11) is provided on one side of the support frame (1) in the vertical direction. The lifting groove (11) runs through the entire length of the support frame (1). The column (3) can pass through the opening of the lifting groove (11) and enter the lifting groove (11). The height of the support frame (1) is not less than the height of the column (3). The lifting device (2) is located on the top of the support frame (1), and the lifting device (2) is detachably connected to the column (3) in the lifting groove (11) and can drive the column (3) to move up and down along the lifting groove (11).
2. A confined space steel pipe column lifting apparatus according to claim 1, characterised in that: It also includes a clamp (4), which is connected to the wall of the lifting groove (11) and has a limiting hole. The wall of the limiting hole can abut against the column (3) located in the lifting groove (11) and restrict the column (3) from moving along the width direction of the lifting groove (11).
3. A confined space steel pipe column lifting apparatus according to claim 2, characterised in that: The clamp (4) includes a pair of clamp (4) plates and a pair of abutment plates (42). Each clamp (4) plate has a through-hole, and each through-hole has a pin (43) inserted into it. The lifting groove (11) has two fixing holes on its wall, which correspond one-to-one with the clamp (4) plates. Each clamp (4) plate is pinned to the support frame (1) through the corresponding fixing hole via the pin (43) on the clamp (4) plate. The abutment plates (42) correspond one-to-one with the clamp (4) plates. Each of the abutting plates (42) is connected to the side of the corresponding clamp (4) away from the pin (43) on the clamp (4). Abutting notches are formed on the side of the two clamps (4) away from their own pins (43). When the surfaces of the two clamps (4) are parallel to the horizontal plane, the two abutting notches can be joined together to form the limiting hole. The two abutting plates (42) can abut against each other and restrict the side of the two clamps (4) away from their own pins (43) from rotating downward.
4. The confined space steel pipe column lifting apparatus according to claim 1, wherein: The lifting device (2) is a hand chain hoist. The column (3) has a connecting ear (32) on its bottom side. The hook of the hand chain hoist can be connected to the connecting ear (32).
5. A confined space steel pipe column lifting apparatus according to claim 4, characterised in that: It also includes an auxiliary assembly (5), which includes a support plate (51), a connecting rod (52), and a lifting unit (53). One side of the support plate (51) is hinged to the support frame (1), and the other side of the support plate (51) is hinged to the top of the connecting rod (52). The bottom end of the connecting rod (52) is provided with a locking rod (521). The support frame (1) has a waist-shaped hole in the vertical direction. The wall of the lifting groove (11) has a connecting hole leading to the bottom end of the waist-shaped hole. The locking rod (521) can pass through the connecting hole. The hole is inserted into the waist-shaped hole and abuts against the wall of the waist-shaped hole. When the clamp rod (521) is located in the waist-shaped hole, the top surface of the support plate (51) extends into the lifting groove (11) and can abut against the bottom end of the column (3). The lifting unit (53) is connected to the clamp rod (521) in a transmission manner, and the lifting unit (53) can drive the clamp rod (521) to rise and fall along the waist-shaped hole and drive the column (3) on the support plate (51) near the connecting rod (52) to rise and fall.
6. A confined space steel pipe column lifting apparatus according to claim 5, characterised in that: The lifting unit (53) includes an eccentric wheel (531) and a throttle (532). The eccentric wheel (531) is rotatably connected to the support frame (1). The bottom end of the connecting rod (52) is rotatably connected to an abutment wheel (522).
