Abstract
The utility model relates to the construction field of reinforced concrete pipelines, and in particular relates to a turnover hoisting tool for a reinforced concrete pipe joint. The turnover hoisting tool comprises a portal frame, two lifting lugs, two coaxial through holes, two coaxial pipe joint hoisting holes, and two pin bolts, wherein the two lifting lugs are symmetrically arranged on the top of the portal frame; the two coaxial through holes are formed on the two sides of the portal frame; the two coaxial pipe joint hoisting holes are symmetrically formed on the pipe wall of the reinforced concrete pipe joint; and the two pin bolts are matched with the through holes and the hoisting holes for use. The turnover hoisting tool adopts the design, so that the reinforced concrete pipe joint is convenient to position and hoist, thus hoisting operation safety for large-diameter and large-weight reinforced concrete pipe joints is improved.
Description
Technical field
The utility model relates to the concrete duct construction field, is specially a kind of upset lifting device of ferro-concrete tube coupling.
Background technology
Because the prefabricated reinforced concrete tube coupling has the advantages such as economical and practical, that stress performance is excellent, is widely used in the pipe-jacking project.Yet, excessive because of its deadweight, give safety, successfully tube coupling is lifted to upper pipe working well by ground brought difficulty.At present, lifting ferro-concrete tube coupling mainly contains two kinds of methods: 1) cooperate the purlin car to lift special steel wire penetrating cement concrete tube coupling; 2) utilize girder steel to add two hoist cables and cooperate the hoist ceiling crane lifting.First method causes the cement concrete that contacts with steel rope damaged because of extruding in hoisting process easily.Second method lifting minor diameter concrete pipe is more convenient, but when hoisting large-size ferro-concrete tube coupling, tube coupling may come off from hoist cable, exists larger potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the existing defective of method of existing lifting ferro-concrete tube coupling, provides a kind of hoisting process steady, safe, makes the upset lifting device of simple ferro-concrete tube coupling.
In order to achieve the above object, the utility model is achieved in that
A kind of upset lifting device of ferro-concrete tube coupling, two hangers, the symmetries that it comprises portal frame, be located at both sides, portal frame top are opened in two coaxial through-holes on the portal frame dual-side, symmetry is opened in two coaxial tube coupling holes for hoist on the reinforced concrete pipe pipe joint wall, and mates two pins that use with through hole and tube coupling hole for hoist.
The upset lifting device of described ferro-concrete tube coupling also comprises the upset hanger that is embedded in ferro-concrete tube coupling one end.
The upset lifting device of described ferro-concrete tube coupling, the degree of depth of tube coupling hole for hoist is more than or equal to 15 centimetres.
The utility model adopts above-mentioned design, so that the ferro-concrete tube coupling is convenient to be positioned, lift, thus the safety that has improved the lifting operation of major diameter, heavy weight ferro-concrete tube coupling.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the structural representation of ferro-concrete tube coupling.
The specific embodiment
Below further specify the utility model by specific embodiment.
As shown in Figure 1 and Figure 2, a kind of upset lifting device of ferro-concrete tube coupling, two hangers 4, the symmetries that it comprises portal frame 1, be located at both sides, portal frame 1 top are opened in two coaxial through-holes on portal frame 1 dual-side, symmetry is opened in two coaxial tube coupling holes for hoist 5 on ferro-concrete tube coupling 6 tube walls, and mates two pins 2 that use with through hole and tube coupling hole for hoist 5.
The upset lifting device of described ferro-concrete tube coupling also comprises the upset hanger 7 that is embedded in ferro-concrete tube coupling 6 one ends, and for reaching best upset control effect, upset plane, hanger 7 place should be vertical with plane, tube coupling hole for hoist 5 place.
The upset lifting device of described ferro-concrete tube coupling, the degree of depth of tube coupling hole for hoist 5 is more than or equal to 15 centimetres.
The utility model adopts above-mentioned design, so that the ferro-concrete tube coupling is convenient to be positioned, lift, thus the safety that has improved the lifting operation of major diameter, heavy weight ferro-concrete tube coupling.
Use the step of this lifting device as follows:
The first step links to each other with the hanger 4 on 1 one on two steel wire penetrating portal frame tops and with the hoisting crane hook.
Second step is with sling portal frame 1 and to tube coupling hole for hoist 5 positions of hoisting crane.
The 3rd step, two pins 2 are passed insert behind the through hole on the portal frame 1 in the tube coupling hole for hoist 5 that ferro-concrete tube coupling 6 reserves, with hoisting crane ferro-concrete tube coupling 6 is promoted overhead certain altitude.At this moment, under ferro-concrete tube coupling 6 action of gravitations, pin 2 will be inwardly stuck in tube coupling hole for hoist 5, to guarantee hoisting process safety.
In the 4th step, with another root steel wire penetrating upset hanger 7, with second this steel rope of crane lifting, make ferro-concrete tube coupling 6 integral inclinations, until the axis of ferro-concrete tube coupling 6 becomes greater than the 45° angle position with plumb line.At this moment, under ferro-concrete tube coupling 6 Gravitative Loads, ferro-concrete tube coupling 6 will be finished the upset of horizontal direction automatically.In this process, the overweight machine of First remains quiescence.
The 5th step removed steel rope from upset hanger 7, the First hoisting crane slowly hangs in ferro-concrete tube coupling 6 in the upper pipe working well.
The 6th step, after lifting is finished, rotate pin 2, it is extracted in tube coupling hole for hoist 5, finish lifting operation and withdraw portal frame 1.
