Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6, the utility model discloses a dig a major diameter overlength steel reinforcement cage hoist and mount auxiliary device soon. The practical engineering is taken as an example to explain the implementation principle and the details of the used equipment in the present application. 79 bored piles are excavated in a rotary mode in the actual engineering. Wherein: 198m for phi 1600 piles, 1001m for phi 1700 piles, 748.8m for phi 1800 piles, 168m for phi 2000 piles and 1092m for phi 2500 piles, totaling 3207.8 m. The length of the reinforcement cage 4 to be hoisted is 28-42 m, and integral manufacture and integral hoisting are adopted.
The main crane 1 adopts a 300-ton crawler crane to hoist the head of the reinforcement cage 4, and is finally responsible for hoisting the reinforcement cage 4 into the pile hole; the auxiliary crane 2 adopts a 220-ton crawler crane to hoist the middle position of the reinforcement cage 4 to the tail part. The whole steel reinforcement cage 4 is hung vertically, rotates in the air to determine the position, then slowly falls into the pile hole, falls to the bottom, and is straightened and fixed.
Therefore, the hoisting auxiliary device for hoisting the reinforcement cage 4 is newly designed, is used for assisting the main crane 1 and the auxiliary crane 2 to connect the reinforcement cage 4, and is matched with the reinforcement cage 4 to complete the actions of turning over (changing from a horizontal state to a vertical state), positioning the reinforcement cage 4 and dropping the reinforcement cage 4 into the pile hole during the integral hoisting of the reinforcement cage 4.
The hoisting auxiliary device comprises a sliding component 3 connected with a circular lifting lug 5 connected with a steel reinforcement cage 4 and a lifting hook. The circular lifting lug 5 is formed by welding Q235 steel plates and is circular integrally. Four section steels 7 are arranged on the inner ring surface of the circular lifting lug 5, the respective ends of the four section steels 7 are connected in pairs to form a square frame, and four corners of the square frame are respectively welded with the inner ring surface of the circular lifting lug 5. In practice, the section steel 7 is a 100X 20I-steel. And, still include the stirrup 6 of putting more energy into, this stirrup 6 of putting more energy into is whole to be the triangle-shaped. In the specific implementation: three angular points of the stiffening stirrup 6 are welded to the reinforcement cage 4 respectively, so that the reinforcement cage 4 is prevented from being deformed due to overlarge local stress during hoisting. Typically, the stiffening stirrups 6 are located inside the reinforcement cage 4, and it is most appropriate to provide one stiffening stirrup 6 every 2 meters along the length of the reinforcement cage 4.
Slip subassembly 3, including connecting the main part, connecting the main part's upside is equipped with and connects ear 31, should connect ear 31 to be used for hanging 1 or assisting the lifting hook that hangs 2 and carry out hook fixed connection with the main, and connecting the main part's downside then inwards caves in and is formed with the recess, rotate side by side from a left side to the right side in proper order in the recess and be connected with first pulley 32, second pulley 33 and third pulley 34, first pulley 32 and second pulley 33 are close to connect ear 31, second pulley 33 then keeps away from connect ear 31, constitute a rolling passageway that can supply wire rope 8 to pass through by first pulley 32, second pulley 33 and second pulley 33. As shown by the arrows in fig. 4, the wire rope 8 is wound up and down around the first pulley 32, the second pulley 33, and the third pulley 34. After the connecting lug 31 is connected with the hook, the two ends of the steel wire rope 8 bypassing the rolling channel can be just downwards connected with the reinforcement cage 4. Of course, the direction indicated by the arrows may vary.
In further optimization, the first pulley 32 and the third pulley 34 are both provided with a guide block 9, the guide block 9 is splayed, two end parts of the guide block 9 are both provided with guide holes for the steel wire rope 8 to pass through, the middle part of the guide block 9 is coaxially and rotatably connected with the first pulley 32 or the third pulley 34, and the first pulley 32 and the third pulley 34 respectively correspond to one guide block 9. When the steel cable 8 passes through the rolling channel, the steel cable also passes through the guide hole on the guide block 9. As long as the coupling ears 31 are directed upward and coupled to the hooks (hooks of the main hanger 1 or the auxiliary hanger 2) at all times, the coupling body is directed downward by gravity, and the guide block 9 is directed downward by gravity, and both ends of the guide block 9 are directed at all times, as shown in fig. 2 and 5. The two ends of the guide block 9 are just correspondingly matched with the passing direction of the steel wire rope 8 on the first pulley 32 or the third pulley 34, so that the steel wire rope 8 is firmly limited in the sliding groove of the first pulley 32 or the third pulley 34 by using the guide hole, and the steel wire rope 8 is prevented from falling out of the rolling channel. Even if the connecting body has some deflection, as long as the connecting lug part 31 is hoisted by the lifting hook, the steel wire rope 8 can be stably limited in the rolling channel by the guide block 9, and further quality and safety accidents caused by the falling of the steel wire rope 8 are avoided.
The whole hoisting process of the reinforcement cage 4 is shown in fig. 1 and 2:
the first step is as follows: the reinforcement cage 4 is firstly placed on the stock ground by the other side, and the whole reinforcement cage 4 is in a horizontal state at the moment.
The second step is that: a plurality of circular lifting lugs 5 are welded along the length direction of the reinforcement cage 4, and of course, each circular lifting lug 5 is welded and connected with the reinforcement cage 4 through the outer annular surface thereof.
The third step: a steel wire rope 8 is connected to a hook of the main crane 1, and the steel wire rope 8 on the main crane 1 is connected with a circular lifting lug 5 positioned at the end of the reinforcement cage 4 through four section steels 7 on the circular lifting lug 5; the hook on the auxiliary crane 2 is firstly connected with the sliding component 3, then a second steel wire rope 8 is arranged in a rolling channel of the sliding component 3, and the second steel wire rope 8 is connected to the reinforcement cage 4 through two ends of the steel wire rope 8. It should be noted that all the connections between the wire ropes 8 and the reinforcement cage 4 are performed by using the circular lifting lugs 5.
The fourth step: the steel reinforcement cage 4 is horizontally lifted upwards by the main crane 1 and the auxiliary crane 2, and then under the condition that the hook of the auxiliary crane 2 is not moved, the hook of the main crane 1 continues to lift the steel reinforcement cage 4 upwards until the steel reinforcement cage 4 reaches the state shown in fig. 2. It should be noted that: in this process, the connecting position of the wire rope 8 connected to the sliding component 3 and the sliding component 3 is constantly changed, and the change is formed by the wire rope 8 constantly rolling and sliding along the rolling channel formed by the first pulley 32, the second pulley 33 and the third pulley 34.
The fifth step: after the steel reinforcement cage 4 is vertically hoisted, the auxiliary hoist 2 is used for positioning the steel reinforcement cage 4 to be far away from the lower end of the hook of the main hoist 1 until the steel reinforcement cage 4 is positioned to the pile hole, then the steel wire rope 8 for connecting the auxiliary hoist 2 with the steel reinforcement cage 4 is removed, and finally the main hoist 1 is used for integrally hoisting the steel reinforcement cage 4 into the pile hole.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
