Specific implementation method:

[0026] The present invention is further described below with reference to specific embodiments. Figure 1 —6:

[0027] A driving device for pile driving equipment is used in conjunction with an excavator, including a pile driver assembly, the pile driver assembly including a left side plate 1 and a right side plate 2 arranged at intervals on the left and right, a top plate 3 is arranged on the upper ends of the left side plate 1 and the right side plate 2, and the left side plate 1 and the right side plate 2 are connected by a plurality of connecting columns 4. The connecting column 4 can keep a certain distance between the left side plate 1 and the right side plate 2. An oil cylinder 5 is arranged between the left side plate 1 and the right side plate 2, and the oil circuit that should be available on the excavator itself is utilized, so the present invention selects an oil cylinder, and of course, a cylinder, a screw rod and other structures can also be used. The oil cylinder 5 is connected to the top plate 3, and the piston rod 6 of the oil cylinder 5 is arranged downward, and a driving head 8 for connecting with the pile core 7 of an underground flowering pile is arranged on the piston rod 6; a sling for connecting with the pile sleeve 9 of the underground flowering pile is arranged on the left side plate 1, the right side plate 2 or the top plate 3. The oil cylinder 5 of the present invention is hinged with the top plate 3, which is convenient for automatically fine-tuning the angle between the oil cylinder 5 and the top plate 3, and avoiding the connection between the oil cylinder 5 and the bracket of the top plate 3 from breaking. The action of the oil cylinder 5 is operated in the cab of the excavator. A front limit rod 10 and a rear limit rod 11 are provided between the left side plate 1 and the right side plate 2 to limit the front and rear positions of the oil cylinder 5, and the front limit rod 10 and the rear limit rod 11 are located at the front and rear sides of the oil cylinder 5. A pile pressing part that can press the pile sleeve cross arm 22 on the pile sleeve 9 is provided at the lower ends of the left side plate 1 and the right side plate 2. The pile pressing part of the present invention is a notch 28 provided at the lower ends of the left side plate 1 and the right side plate 2, and the top of the notch 28 is pressed on the upper plane of the pile sleeve cross arm 22. When the pile core 7 of the underground flowering pile is pulled up, the pile sleeve 9 is pressed by the pile sleeve cross arm 22. At this time, the pile sleeve 9 and the pile core 7 form an up and down reverse motion, and finally achieve the purpose of underground flowering of the underground flowering pile.

[0028] The present invention is provided with a connection part connected with an excavator at the rear end of the upper part of the left side plate 1 and the right side plate 2. The connection part is provided with an axle pin hole commonly matched with an excavator. The present invention realizes connection with the excavator through a connecting axle pin 29, and the connection is very convenient and has strong versatility.

[0029] The lifting device of the present invention comprises a lifting ring 13 and a piling lifting chain 14, wherein the lifting ring 13 is connected to the top plate 3 or the left side plate 1 and the right side plate 2 through the piling lifting chain 14. In this embodiment, the left and right ends of the top plate 3 extend out of the left side plate 1 and the right side plate 2. The upper ends of the piling lifting chain 14 are connected to the bottom surfaces of the two ends of the top plate 3.

[0030] like Figure 1 , 2, 3, 5, and 6, in order to enable the sling of this embodiment to achieve the effect of automatic detachment, the sling also includes a detachment chain seat 12, a lifting ring 13 is connected to the detachment chain seat 12, a locking bolt mounting hole is provided on the detachment chain seat 12, a locking bolt 15 is installed in the locking bolt mounting hole, and the locking bolt 15 is connected to the driving head 8 through the detachment chain 16. The left side plate 1 and the right side plate 2 are provided with guide chutes 17 in the up-down direction, and the upper end of the detachment chain 16 passes through the guide chute 17 and is connected to the driving head 8.

[0031] In order to prevent the driving head 8 from shaking back and forth, the upper end of the de-slinging chain 16 is connected to a guide column 18, and the guide column 18 is arranged in the guide chute 17 and can move up and down along the guide chute 17 with the driving head 8. One end of the guide column 18 is connected to the driving head 8, and the other end extends out of the guide chute 17 and is connected to one end of the de-slinging chain 16.

[0032] The distance between the two sides of the drive head 8 of the present invention is adapted to the distance between the left plate 1 and the right plate 2. In actual use, the distance between the two sides of the drive head 8 is slightly smaller than the distance between the left plate 1 and the right plate 2, which can reduce the shaking of the drive head 8 in the left and right directions.

[0033] Another example Figure 1 , 2 As shown in Figures 3, 5 and 6, a left limiting plate 19 and a right limiting plate 20 are respectively arranged on the outer sides of the left side plate 1 and the right side plate 2, and a limiting chute 21 is respectively arranged on the left limiting plate 19 and the right limiting plate 20, and the piling lifting chain 14 and the detaching chain 16 pass through the limiting chute 21 and are connected to the detaching chain seat 12. The limiting chute 21 can limit the piling lifting chain 14 and the detaching chain 16 in the front, back, left and right directions to prevent the detaching chain 16 from being tightened without authorization and accidentally detaching.

[0034] The pile sleeve cross arm 22 of the present invention is connected to the hanger through a connecting piece.

[0035] When the lifting device of this embodiment has an automatic lifting-off structure, the connecting piece is preferably a pile rope 23 .

[0036] When the sling of the present invention does not need the automatic release function, a normal safety hook or the like can also be selected.

[0037] Among them, the specific working principle of automatic lifting is as follows:

[0038] Before lifting, the piston rod 6 of the oil cylinder 5 is lowered to the lower starting point, and the automatic lifting ring forms a lifting state. The pile hanging rope 23 is inserted into the corresponding hole or the connecting ring buckle on the pile sleeve cross arm 22, and the other end of the pile hanging rope 23 passes through the lifting ring 13 and is locked by the locking bolt 15, thereby realizing the connection between the pile hanging rope 23 and the pile sleeve cross arm 22.

[0039] During lifting, the unloading chain 16 is in a relaxed state, the lifting chain 14 is in a tightened state, the locking bolt 15 is in a lifting state on the lifting ring 13 , and the pile rope 23 is tightened on the locking bolt 15 .

[0040] When the lifting is removed, one end of the lifting chain 16 rises synchronously with the driving head 8 until the lifting chain 16 is at the Half The tension state, and the pile driver top is tilted forward, so that the sling pulling lock bolt 15 is automatically taken off. At this moment, the pile core cross arm 26 and the pile sleeve cross arm 22 also synchronously break away from this pile driver.

[0041] After each underground flowering pile is driven, when the platform beam is installed, the interlocking bolts are twisted open and the pile hanging rope 23 is retracted.

[0042] The longitudinal cross section of the driving head 8 of the present invention is a square shape with an open bottom, and an inner convex edge 24 extends inward from the open end. The distance between the two inner convex edges 24 can accommodate the pile core 7 of the underground flowering pile, and a pile core cross arm 26 is provided on the pile core 7, and the two ends of the pile core cross arm 26 extend out of the pile core 7, and the two ends of the pile core cross arm 26 abut on the upper plane of the inner convex edge 24.

[0043] For example Figure 1 , 2 As shown in FIGS. 3, 5 and 6, the lower ends of the left side plate 1 and the right side plate 2 are provided with a pile pulling lifting chain 25, which is sleeved on the front side of the pile sleeve 9. When pulling out the pile, the pile pulling lifting chain 25 can be clamped on the pile sleeve cross arm 22 and cooperate with the pile driver to pull up the underground flowering pile. After the underground flowering pile is pulled up, when the underground flowering pile is laid down, the pile pulling lifting chain 25 can always support the underground flowering pile to make it fall down slowly, thereby improving the safety of the operation.

[0044] The operation process of the present invention is as follows:

[0045] Before piling, the underground flowering pile is placed upside down on the ground, and the operator connects the pile hanging rope 23 to the hanging device. At this time, the operating arm of the excavator drives the present invention to move upward, and slowly lifts one end of the underground flowering pile through the hanging device. When one end of the underground flowering pile is lifted to a certain height, the upper end of the pile core 7 of the underground flowering pile automatically enters between the two inner convex edges 24 of the driving head 8, and the pile core cross arm 26 is located above the upper plane of the two inner convex edges 24. When the underground flowering pile is completely lifted, the underground flowering pile is hung on the driving head 8 through the pile core cross arm 26. At this time, the piston rod 6 of the oil cylinder 5 is in an extended state.

[0046] When driving piles, the operating arm of the excavator drives the underground flowering pile downward and inserts it into the ground. After the underground flowering pile is inserted into place, the piston rod 6 of the oil cylinder 5 is retracted upward, driving the pile core 7 to move upward, and the pile sleeve cross arm 22 is pressed into the gap 28 of the left side plate 1 and the right side plate 2 until the underground flowering pile is located in the underground pile plate 27. The underground flowering is realized. After the flowering is completed, the lifting chain 16 is tightened, and the lock bolt 15 is pulled to achieve automatic lifting. The underground flowering pile is completely separated from the present invention.

[0047] When pulling piles, the excavator drives the pile pulling lifting chain 25 of the present invention to hook the pile sleeve cross arm 22, forming a pile pulling state. The excavator drives the pile sleeve 9 to move upward through the pile pulling lifting chain 25, and the pile plate 27 slowly closes. After the pile sleeve 9 is reset, the pile core 7 and the pile sleeve 9 leave the pile position together.

[0048] After the excavator moves the underground flowering pile to the corresponding position, the operating arm of the excavator drives the underground flowering pile to slowly fall to the ground (the lower end of the underground flowering pile is located on the ground, and the upper end slowly falls toward the ground). When the upper end of the underground flowering pile falls to a certain height, the upper end of the underground flowering pile automatically falls to the ground.

[0049] The terms such as "upper", "lower", "left", "right", "middle" and "one" etc. used in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships shall be regarded as within the scope of implementation of the present invention without substantially changing the technical content.

[0050] The above embodiment is only one of the preferred embodiments of the present invention, and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the protection scope of the present invention.
