[0014] In the figure: 1 - suspension rod frame, 2 - top frame, 3 - lifting suspension rod, 4 - bottom hook frame, 5 - clamping plate. Detailed Implementation Modes Embodiment

[0015] As Figure 1-Figure 2 shown, a U-shaped lifting sling device includes a suspension rod frame 1, a top frame 2, a lifting suspension rod 3, a bottom hook frame 4, and a clamping plate 5. The top of the vertical suspension rod frame 1 is fixed to the horizontal top frame 2, and the bottom is fixed to the horizontal bottom hook frame 4. The three form a U shape. Multiple groups of horizontal lifting suspension rods 3 are arranged on the top frame 2 for connecting with hoisting rigging and changing the lifting position according to the on-site situation. The end of the bottom hook frame 4 is connected to a vertical clamping plate 5, and the whole device is fixed to the bottom of the cantilever bottom die frame through the clamping plate 5.

[0016] The suspension rod frame 1 is formed by connecting two full-length ∠80*8mm equal-angle steel bars and the ∠80*8mm equal-angle steel bars of the horizontal rod and the diagonal rod between them into an integral frame. The top of the suspension rod frame 1 is welded and fixed to the top frame 2, and the bottom is welded and fixed to the horizontal bottom hook frame 4.

[0017] The top frame 2 is two back-to-back full-length 200mm channel steels, and the outer side of the channel steel rib plate is welded and reinforced with the suspension rod frame 1.

[0018] The lifting suspension rod 3 is a 30mm round steel bar with a length of 120mm, and there are eight groups in total. It is connected to the outer side of the rib plate of the top frame 2 through high-strength nuts.

[0019] The bottom hook frame 4 is a simple truss structure formed by two rows of four full-length 80mm channel steels, and a convex clamping plate 5 is arranged at the front end of the bottom hook frame 4.

[0020] The clamping plate 5 is a 10mm thick Q235 convex steel plate, which is fixed to the bottom of the cantilever bottom die frame.

[0021] As Figure 3As shown in the figure, the working principle of the utility model is described as follows: The installation and disassembly of the cantilever bottom formwork are completed by manually lifting the U-shaped hoisting sling device to act as a balance frame. The specific steps are as follows:

[0022] The first step: Fabricate the U-shaped hoisting sling device. First, cut the suspension rod frame 1, top frame 2, hoisting suspension rod 3, bottom hook frame 4, and clamping plate 5 into shape according to the design drawings. Then, first process the suspension rod frame 1, and then weld the top frame 2 and the bottom hook frame 4 to the suspension rod frame 1 respectively to form an integral body. Then, supplement the hoisting suspension rod 3 and the clamping plate 5 in sequence.

[0023] The second step: In actual operation, after the bottom formwork is assembled, the operator connects the hoisting suspension rod 3 at the top of the U-shaped hoisting sling device to the main rigging of the lifting equipment, then hoists it to the bottom of the bottom formwork frame, connects it through the clamping plate 5 of the sling device itself, and then the hoisting rigging lifts and lowers the cantilever bottom formwork. Because there are multiple groups of hoisting suspension rods 3, the position of the hoisting suspension rod 3 can be adjusted according to the self-weight position during the process to effectively solve the eccentricity problem of the lifted component.

[0024] The utility model is applicable to the installation and removal of the cantilever bottom formwork, and is also applicable to the hoisting balance hanger of similar structures. It is simple to operate, convenient to disassemble, and improves construction efficiency and safety.
