Hoisting the steel reinforcement cage 1 through a hoisting machine, and passing the steel reinforcement cage 1 through the base 201 perforated hole 4 to be lowered towards the pile hole.
In the process of lowering the reinforcement cage 1 toward the pile hole, the abutting rod 32 abuts against the first abutting plate 202 prior to the reinforcement cage 1. In the process, the resisting rod 32 drives the third baffle 31 to slide upwards along the length direction of the vertical rod 2401, so that the second sliding rod 27 is separated from the third baffle 31 to be abutted, the sleeve 2403 slides downwards along the length direction of the vertical rod 2401 under the action of the second spring 30, and the sleeve 2403 drives the second sliding rod 27 to penetrate out of the cross rod 2402 through the inclined rod 29. After the steel reinforcement cage 1 enters the pile hole, the second slide bar 27 can be abutted against the inner wall of the pile hole through the rollers 36, because the axis of the vertical bar 2401 is the same as the axis of the steel reinforcement cage 1, and the lower end of the vertical bar 2401 is vertically connected with the two cross bars 2402, the rollers 36 on the second slide bar 27 respectively penetrating out of the two cross bars 2402 are abutted against the inner wall of the pile hole, so that the condition that the steel reinforcement cage 1 is deviated in the falling process in the pile hole is effectively avoided.
Afterwards, the lower extreme and the first butt plate 202 looks butt of steel reinforcement cage 1, because the rotation junction of first butt plate 202 and base 201 is provided with and is used for first butt plate 202 towards the skew first torsional spring 6 of trompil 4 axis, make on the one hand first butt plate 202 rotate the back and form the passageway that supplies steel reinforcement cage 1 to pass, on the other hand makes the upper end of first butt plate 202 rotate towards trompil 4 axis under the effect of steel reinforcement cage 1's butt, thereby make the lower extreme of first butt plate 202 drive second baffle 13 and move towards trompil 4 through the connecting piece that is connected rope 14 rather than linking to each other. The second baffle 13 is pulled to the position, away from the abutting connection, of the second chute 10 and the first baffle 11, so that the first baffle 11 can penetrate into the second chute 10 through the first chute 7 through the channel 12 under the action of gravity, and the first baffle 11 and the second abutting plate 8 are separated from the abutting connection.
Because when the first baffle 11 abuts against the second abutting plate 8, the first spring 9 is in a compressed state, after the second abutting plate 8 is separated from the first baffle 11, the second abutting plate 8 can move towards the inside of the open hole 4 under the action of the first spring 9, so that the second abutting plate 8 abuts against the reinforcement cage 1. Because the second buttressing plate 8 is provided with six, six second buttressing plates 8 all are connected with steel reinforcement cage 1 butt under the effect of telescopic link 23 to make steel reinforcement cage 1 fix a position steel reinforcement cage 1 at the in-process of whereabouts. Consequently, prevent 1 off normal of steel reinforcement cage at the in-process that steel reinforcement cage 1 got into the stake hole through first locating component 2 in stake hole top, simultaneously, the tip that steel reinforcement cage 1 got into the stake hole prevents off normal through second locating component 24, can prevent that steel reinforcement cage 1 from taking place the off normal at the in-process that the stake was downthehole to transfer.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
