Description

Technical Field

[0001] This utility model relates to a rapid hoisting device for prefabricated rubber spring floating slabs, belonging to the field of urban rail transit technology. Background Technology

[0002] In the hoisting and installation of precast slabs for rubber spring floating slab track in urban rail transit, the conventional method of pre-embedded sleeves and lifting lugs is generally adopted. Each precast slab weighs approximately twelve tons, requiring high-quality pre-embedded sleeves. With four lifting points per slab, the hoisting and disassembly of the precast slab requires sixteen adjustments to the sleeve bolts, making operation inconvenient. Furthermore, the lifting lugs are located on both sides of the precast slab, causing the wire ropes to be subjected to oblique stress, posing certain safety hazards. Additionally, in tunnels with a diameter of 5500mm, the space is limited, and the requirements for rough laying and fine adjustment of the precast slabs are high. The lifting lugs occupying space can prevent the precast slabs from being laid in one go, leading to secondary construction and affecting construction efficiency. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the protection scope of the present invention.

[0020] This utility model discloses a rapid hoisting device for prefabricated rubber spring floating slabs, used in conjunction with an outer sleeve of the rubber spring floating slab. The outer sleeve serves as a major load-bearing device for subway operation, and the hoisting force of the prefabricated slab meets design requirements. The outer sleeve has an upper locking groove and a lifting locking groove in the vertical direction. Figure 1 and Figure 2As shown, the rapid hoisting device of this utility model includes a vertically arranged hoisting plate 1. A hoisting hole 3 is provided at the upper part of the hoisting plate 1 for a hoisting pin to pass through. A retaining strip 2 is provided on the hoisting plate 1 below the hoisting hole 3. An integrally connected stop part 6 is provided at the lower part of the hoisting plate 1. A first steel plate 4 and a second steel plate 5 are fitted onto the hoisting plate 1 in a vertical direction. The first steel plate 4 is located below the retaining strip 2, and the second steel plate 5 is located above the stop part 6. In this utility model, the retaining strip 2 is used to prevent the first steel plate 4 and the second steel plate 5 from falling off the hoisting plate 1, and the stop part 6 is used to support the second steel plate 5.

[0021] like Figure 3 and Figure 4 As shown, the first steel plate 4 and the second steel plate 5 are the same size and shape, corresponding to the shapes of the upper slot and the lifting slot. The first steel plate 4 and the second steel plate 5 are respectively provided with a first slot 41 and a second slot 51 for the lifting plate 1 to pass through. The first slot 41 and the second slot 51 are the same in shape and size. The first steel plate 4 is located in the upper slot to prevent the lifting device from twisting and falling off during the lifting process. The second steel plate 5 cooperates with the lifting slot to bear the force of the lifting device. The first slot 41 and the second slot 51 are staggered vertically, with a certain rotation angle between them. A stop strip 42 is provided on the side of the first steel plate 4, located above the upper slot, to prevent the first steel plate 4 from falling into the outer sleeve.

[0022] The working principle of this utility model is as follows: First, manually lift the first steel plate 4, then align the second steel plate 5 with the upper slot, and slowly lower the hoisting device so that the second steel plate 5 passes through the upper slot and the lifting slot in sequence. Then rotate it at a certain angle so that the first steel plate 4 is aligned with the upper slot. At this time, the second steel plate 5 is staggered from the lifting slot. Then slowly lower the first steel plate 4 so that the first steel plate 4 is just inserted into the upper slot. The stop bar 42 prevents the first steel plate 4 from falling. Finally, the subsequent hoisting process is carried out.

[0023] This utility model lifting device is a one-time investment that can be reused. It is small in size, easy to install and dismantle, safe and reliable, and greatly improves construction efficiency. Moreover, the use of this tooling can reduce construction investment and costs.
