Detailed Description
As shown in fig. 1 and 2, the utility model comprises a bearing mechanism arranged on the concrete pile head 1 to be broken for bearing the concrete pile head 1 to be broken, a supporting mechanism arranged at the bottom of the concrete pile head 1 to be broken for supporting the concrete pile head 1 to be broken, and a rope lifting mechanism arranged at the top of the bearing mechanism for lifting the bearing mechanism; the bearing mechanism comprises a plurality of vertically arranged lifting frames, and a bearing area for bearing the concrete pile head 1 to be broken is formed by surrounding the plurality of lifting frames.
When the concrete pile head lifting device is actually used, the bearing mechanism is arranged to bear the concrete pile head 1 to be broken, so that the phenomenon that the concrete pile head 1 to be broken is unstable in the traditional lifting process to incline and bend and damage the surrounding reinforcing steel bars 9 is avoided; the support mechanism is provided to facilitate the installation of the bearing mechanism while avoiding damage to the head 11 of the main pile in the foundation pit 10.
Wherein, utilize it promotes to carry rope mechanism bear the mechanism, will set up simultaneously bear the weight of waiting to abolish concrete pile head 1 in the mechanism and demolish, avoid waiting to abolish concrete pile head 1 to produce and rock, improved the stability of demolising the in-process.
In addition, will wait to abolish concrete pile head 1 and place in the bearing area can avoid in the hoist and mount process waiting to abolish concrete pile head 1 slope, cause the damage to reinforcing bar 9.
In this embodiment, the lifting frame includes a supporting plate 2 horizontally disposed at the bottom of the concrete pile head 1 to be broken and lifting plates 3 vertically disposed at two ends of the supporting plate 2, the supporting plate 2 and the two lifting plates 3 form a U-shaped structure, and an opening of the U-shaped structure faces the concrete pile head 1 to be broken; the end part of the lifting plate 3 far away from the supporting plate 2 is provided with a lifting hole 3-1.
In actual use, the lifting holes 3-1 are arranged to have the following functions: the fixing of the buffer rope 5 is facilitated. The supporting plate 2 and the lifting plate 3 are fixed through welding, after the air bag 4 supports the concrete pile head 1 to be broken, the supporting plate 2 is firstly installed at the bottom of the concrete pile head 1 to be broken, then the lifting plate 3 is welded at two ends of the supporting plate 2 to form the lifting frame, and the lifting frame is combined to realize bearing of the concrete pile head 1 to be broken.
As shown in fig. 1 and 2, in the present embodiment, the support plate 2 is arranged along the diameter direction of the concrete pile head 1 to be broken; the lifting plate 3 is arranged on the outer side of the concrete pile head 1 to be broken and is arranged along the height direction of the concrete pile head 1 to be broken; the lifting plates 3 in the plurality of lifting frames are uniformly distributed along the circumferential direction of the concrete pile head 1 to be broken.
As shown in fig. 1 and fig. 2, the number of the hoisting frames is three, the three support plates 2 in the hoisting frames intersect at a point, and in order to ensure the stability of the concrete pile head 1 to be broken in the hoisting process, the projection of the central axis of the concrete pile head 1 to be broken in the vertical direction on the horizontal plane coincides with the intersection points of the three support plates 2 in the hoisting frames. During practical use, the length of the support plate 2 is larger than the diameter of the concrete pile head 1 to be broken, so that the concrete pile head 1 to be broken is conveniently borne in the bearing area.
In this embodiment, the rope lifting mechanism includes a plurality of buffer ropes 5, one end of each buffer rope 5 is fixed to the corresponding lifting hole 3-1, and the other end of each buffer rope 5 is fixedly connected to the corresponding traction steel wire rope 6.
