AI Technical Summary
In bridge construction, existing technologies require manual disassembly of lifting rings at heights, which poses high risks and increases construction costs. At the same time, shortening the length of steel pipe piles leads to more joints and low efficiency.
Design a steel pipe lifting device that is easy to disassemble at height. It adopts a structure of two lifting rods, a crossbeam and a tie rod. The device can be separated from the steel pipe pile by pulling ropes on the ground, thus avoiding high-altitude operations.
It reduces the risks of high-altitude construction, improves the efficiency of steel pipe pile extension and driving, and reduces the need for high-altitude operations.

TECHNICAL FIELD
[0001] The utility model belongs to bridge construction technical field relates to a steel pipe lifting appliance convenient to high altitude dismantling for the vertical lifting of crane steel pipe pile or steel casing to carry out butt joint. BACKGROUND
[0002] In the process of bridge construction, sometimes it is necessary to insert and drive an ultra-long steel pipe pile, and the ultra-long steel pipe pile needs to be lengthened by multiple steel pipe piles. The common lengthening method is to set up lifting holes on both sides of the upper end of each steel pipe pile, after the first steel pipe pile is inserted and driven, the crane connects the upper end lifting hole of the second steel pipe pile through a lifting ring or a lifting rope to lift, aligns the lower end of the second steel pipe pile with the upper end of the first steel pipe pile and welds them, after the welding is completed, the lifting ring connecting the crane and the steel pipe pile is removed, and after the steel pipe pile is inserted and driven to the designed depth, the subsequent steel pipe piles are successively lifted to continue lengthening. At present, in the construction, the lifting ring at the lifting point of the upper end of the steel pipe pile needs to be manually removed, if the length of the single steel pipe pile is long, the construction personnel need to remove it through the climbing trolley, and multiple high-altitude operations are needed, which not only has high construction risk, but also needs to invest large climbing equipment, thereby increasing the construction cost; if the length of the single steel pipe pile is shortened, the high-altitude construction risk is reduced, but the number of steel pipe pile joints is increased, and the steel pipe pile lengthening and insertion and driving construction efficiency is low. SUMMARY
[0003] The utility model aims at the above problems, provides a kind of steel pipe lifting appliance convenient to high altitude dismantling, under the premise of not shortening the length of single steel pipe pile, reduce high-altitude construction risk.
[0004] The technical scheme of the utility model is as follows:
[0005] A kind of steel pipe lifting appliance convenient to high altitude dismantling, it is characterized by: including two hangers, a crossbeam is welded between the upper end of two hangers, a lifting lug is welded in the middle of the crossbeam, a plug hole is provided between the lower end of two hangers, a pull rod is movably arranged in the plug hole of two hangers, one end of the pull rod extends to the outside of one hanger, a pull ring is arranged on the other end of the pull rod outside the other hanger, and a pull rope is connected to the pull ring.
[0006] By using the utility model, the construction personnel can dismantle the steel pipe pile lifting appliance in the air on the ground through the pull rope, avoid high-altitude construction risk, thereby the length of single steel pipe pile can be increased, and the steel pipe pile lengthening and insertion and driving construction efficiency can be improved. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 It is the front view structure of the utility model and the use state schematic diagram;
[0008] Figure 2 It is the side view structure schematic diagram of the utility model. DETAILED DESCRIPTION
[0009] AsFigure 1 , Figure 2 As shown, this utility model includes two lifting rods 1, a crossbeam 2 welded between the upper ends of the two lifting rods, a lifting lug 3 welded in the middle of the crossbeam, and a through-hole 11 between the lower ends of the two lifting rods. A pull rod 4 is movably inserted through the through-hole of the two lifting rods. One end of the pull rod 4 extends to the outside of one lifting rod, and the other end of the pull rod is provided with a pull ring 5 on the outside of the other lifting rod. A pull rope 6 is connected to the pull ring 5.
[0010] In a specific implementation of this utility model, to ensure the connection strength between the hanger rod and the crossbeam, oblique connecting plates 7 can be welded between the crossbeam and the two hanger rods respectively.
[0011] like Figure 1 As shown, when lifting the steel pipe pile 8, this utility model opens lifting holes on both sides of the upper end of the steel pipe pile. The insertion holes at the lower ends of the two lifting rods 1 of the lifting device are aligned with the two lifting holes at the upper end of the steel pipe pile. The tie rod 4 is passed through the lifting holes on the steel pipe pile and the insertion holes on the two lifting rods to connect the lifting device to the steel pipe pile. The crane connects to the lifting lugs on the crossbeam via a lifting rope, vertically lifting the steel pipe pile 8 above the already driven steel pipe pile. After connecting with the driven steel pipe pile, the crane releases the lifting rope, and the construction workers pull the tie rope 6 at one end of the tie rod on the ground to pull out the tie rod 4, thus separating the lifting device from the steel pipe pile. To make it easier to pull out the tie rod, the tie rope 6 can be set long enough to reduce the angle of inclination. After the tie rod is pulled out, the crane lifts the lifting device back to the ground to lift the next steel pipe pile.
