[0016] Compared with the prior art, the steel sheet pile inserting device for the tower crane foundation in the deep silt stratum of the present invention has the following advantages:

[0017] (1) During the process of the first docking frame being inserted into the insertion slot, both ends of the first docking frame will push the rack. The rack will drive the gear. The gear will drive the support shaft to rotate. The support shaft drives the second arc-shaped lapping plate to rotate and lap to the top of the first arc-shaped lapping plate, forming a lock on the third docking frame. Synchronously, the rack will drive the hanging pin to move. The hanging pin will move into the hanging slot to hang and lock the insertion section of the second docking frame in the inserted state. Thus, during the process of the first docking frame connecting the ends of the two parallel support rails, the locking of the second docking frame and the third docking frame in the inserted state is automatically completed. There is no need for workers to lock the second docking frame and the third docking frame one by one, thereby realizing the locking of the positions of the first stabilizing pile assembly and the second stabilizing pile assembly, which is convenient for operation.

[0018] (2) For the steel sheet pile body completed by inserting and driving, it is necessary to maintain stability. By adjusting the assembly, the second adjusting frame and the first adjusting frame are synchronously adjusted to move, so as to realize that the two second stabilizing plates are tightly attached to two symmetrical first surfaces in the concave surface of the steel sheet pile body, and the first stabilizing plate is tightly attached to the second surface in the concave surface of the steel sheet pile body, and cooperate with the first pile stabilizing assembly to clamp and position the inserted and driven steel sheet pile body.

[0019] Corresponding to the position of the pile to be driven, after adjusting the distance between the pile stabilizing body and the first pile stabilizing assembly, the two second stabilizing plates are adjusted to retract into the second receiving groove through the adjusting assembly, and the first stabilizing plate is adjusted to retract into the first receiving groove. When the steel sheet pile body to be inserted and driven is inserted between the pile stabilizing body and the second pile stabilizing assembly, while limiting and supporting the concave surface of the steel sheet pile body, through rolling support, the friction is reduced, which is beneficial to reducing the friction resistance to the insertion and driving of the steel sheet pile body while stabilizing the insertion and driving direction of the steel sheet pile body.

[0020] Limited by the gap formed by the pile stabilizing roller and the pile stabilizing body, the convex end face and the concave surface of the steel sheet pile body can be supported, which is beneficial to maintaining the stability of the insertion and driving direction of the steel sheet pile body. And during the insertion and driving process, through the rolling support of the first pile stabilizing column, the second pile stabilizing column and the pile stabilizing roller, the friction resistance to the steel sheet pile body in the insertion and driving direction can be further reduced.

[0042] As Figures 1 to 14 shown, in one embodiment, a steel sheet pile driving device for a tower crane foundation in a deep silt stratum includes two parallel support rails 1, and also includes a first docking frame 2, a plurality of second docking frames 3, a plurality of third docking frames 4, and two locking components. The first docking frame 2 is inserted at the ends of the two parallel support rails 1. The first docking frame 2 and the two parallel support rails 1 form a U-shaped frame. A plurality of second docking frames 3 are inserted on the two parallel support rails 1. A first pile stabilizing component is provided on each of the plurality of second docking frames 3. The first pile stabilizing component is used to support the concave surface of the steel sheet pile body 34. A second pile stabilizing component is provided on each of the plurality of third docking frames 4. The second pile stabilizing component is used to support the convex end surface of the steel sheet pile body 34. The two locking components are respectively provided on the two parallel support rails 1. The locking components are used to lock the plurality of second docking frames 3 and the plurality of third docking frames 4 inserted on the same support rail 1;

[0043] Both of the two support rails 1 have insertion slots 101. Both ends of the first docking frame 2 are inserted into the insertion slots 101. A first insertion hole 102 and a second insertion hole 201 are respectively formed at the top of the insertion slot 101 and the top of the first docking frame 2. A positioning pin 202 is commonly inserted into the first insertion hole 102 and the second insertion hole 201.

[0044] First insertion interfaces 5 are respectively formed at the top of the two support rails 1 corresponding to the positions of the second docking frames 3. The second docking frame 3 has an insertion section 301. The insertion section 301 is inserted into the first insertion interface 5 and extends into the interior of the insertion slot 101.

[0045] Docking rails 35 are respectively provided on the side walls of the two support rails 1 corresponding to the positions of the third docking frames 4. The third docking frame 4 is inserted into the docking rails 35.

[0046] The locking assembly includes a rack 6, a plurality of support shafts 7 and a plurality of first arc-shaped lapping plates 8. The rack 6 is slidably inserted into the inner wall of the insertion slot 101. The end of the rack 6 contacts the first docking frame 2. A plurality of hanging pins 9 are fixedly connected to the top surface of the rack 6. Hanging slots 302 are formed at the bottom ends of the plurality of insertion segments 301. The plurality of hanging pins 9 are hung inside the plurality of hanging slots 302. The plurality of support shafts 7 are rotatably connected to the inner wall of the insertion slot 101. The plurality of support shafts 7 penetrate through the support rail 1 and extend to the inner side of the docking rail 35. A gear 10 is fixedly connected to the first end of each of the plurality of support shafts 7. The plurality of gears 10 are engaged with the rack 6. Notch openings 401 are formed in the plurality of third docking frames 4. A second arc-shaped lapping plate 11 is fixedly connected to the second end of each of the plurality of support shafts 7. The plurality of first arc-shaped lapping plates 8 are fixedly connected to the side wall of the support rail 1, and the plurality of first arc-shaped lapping plates 8 are all arranged inside the plurality of docking rails 35. The tops of the plurality of first arc-shaped lapping plates 8 are in contact with the inner surfaces of the plurality of second arc-shaped lapping plates 11.

[0047] It should be understood that during the piling process, according to the number of sheet pile bodies 34 required, the same number of second docking frames 3 and third docking frames 4 are provided. Then, the second docking frames 3 are inserted into different support rails 1 according to the concave surface orientation of the sheet pile bodies 34, and the third docking frames 4 are inserted into different support rails 1 according to the protruding end face direction of the sheet pile bodies 34. The process of docking the second docking frames 3 and the third docking frames 4 is as follows:

[0048] First, the insertion segments 301 of the second docking frames 3 are inserted into the first insertion through openings 5 to insert all the second docking frames 3 onto the support rail 1 first. Then, the third docking frames 4 are inserted into the docking rails 35. During the process of inserting the third docking frames 4 into the docking rails 35, the notch openings 401 will overlap on the surfaces of the support shafts 7.

[0049] Insert the ends of two parallel support rails 1 through the first docking frame 2, and insert them into the first insertion hole 102 and the second insertion hole 201 through the positioning pin 202 to achieve the docking of the two parallel support rails 1 and form a U-shaped frame. Then, support the U-shaped frame through an external device; during the process of the first docking frame 2 being inserted into the insertion slot 101, both ends of the first docking frame 2 will push the rack 6, the rack 6 will drive the gear 10, the gear 10 will drive the support shaft 7 to rotate, and the support shaft 7 will drive the second arc-shaped lapping plate 11 to rotate and lap to the top of the first arc-shaped lapping plate 8 to form a lock on the third docking frame 4. Synchronously, the rack 6 will drive the hanging pin 9 to move, and the hanging pin 9 will move into the hanging slot 302 to hang and lock the insertion section 301 of the second docking frame 3 in the inserted state. Thus, during the process of the first docking frame 2 connecting the ends of the two parallel support rails 1, the locking of the second docking frame 3 and the third docking frame 4 in the inserted state is automatically completed, without the need for staff to lock the second docking frame 3 and the third docking frame 4 one by one, thereby realizing the locking of the positions of the first pile stabilizing assembly and the second pile stabilizing assembly, which is convenient for operation.

[0050] As Figure 8 and Figure 9 shown, in one embodiment, the first pile stabilizing assembly includes a first adjustment cavity 12 opened on the second docking frame 3. Two insertion rods 13 are inserted into the first adjustment cavity 12. Threaded sleeves 14 are fixedly connected to the ends of the two insertion rods 13. An adjustment screw rod 15 is threadedly connected to the threaded sleeves 14. The adjustment screw rod 15 is rotatably connected to the inner wall of the first adjustment cavity 12. The two insertion rods 13 penetrate through the second docking frame 3 and are fixedly connected to a pile stabilizing body 16. The pile stabilizing body 16 has two symmetric first pile stabilizing surfaces 1601 and second pile stabilizing surfaces 1602. It should be understood that by rotating the adjustment screw rod 15, the adjustment screw rod 15 will drive the threaded sleeve 14 to move by threading, and the threaded sleeve 14 will synchronously drive the two insertion rods 13 and the pile stabilizing body 16 to move, so as to realize the adjustable distance between the pile stabilizing body 16 and the second pile stabilizing assembly. The gap between the pile stabilizing body 16 and the second pile stabilizing assembly is suitable for the steel sheet pile body 34 to pass through.

[0051] Specifically, a first adjustment head 17 is fixedly connected to the end of the adjustment screw rod 15, which is convenient for the wrench to perform the adaptation operation.

[0052] As Figures 8 to 13As shown, in one embodiment, first receiving grooves 18 are formed in both of the two first pile stabilizing surfaces 1601. First stabilizing plates 19 are disposed in both of the two first receiving grooves 18. A first adjusting frame 20 is fixedly connected to the first stabilizing plate 19. Second receiving grooves 21 are formed in the second pile stabilizing surface 1602. Second stabilizing plates 22 are disposed in both of the two second receiving grooves 21. A second adjusting frame 23 is fixedly connected between the two second stabilizing plates 22. A plurality of first pile stabilizing columns 24 are rotatably connected to both of the two first pile stabilizing surfaces 1601. A plurality of second pile stabilizing columns 25 are rotatably connected to the second pile stabilizing surface 1602. Specifically, the two second stabilizing plates 22 are symmetrically arranged with reference to the second pile stabilizing columns 25;

[0053] An adjusting assembly is disposed between the second adjusting frame 23 and the first adjusting frame 20. The adjusting assembly includes a second adjusting cavity 26. The second adjusting cavity 26 is formed in the pile stabilizing body 16. The first adjusting frame 20 and the second adjusting frame 23 are both located in the second adjusting cavity 26, and both the first adjusting frame 20 and the second adjusting frame 23 penetrate through the pile stabilizing body 16. A moving frame 27 is slidably disposed in the second adjusting cavity 26. A driving screw 36 is threadedly inserted into the moving frame 27. The driving screw 36 is rotatably connected in the second adjusting cavity 26. The moving frame 27 includes two first guiding grooves 28 and one second guiding groove 30. The first guiding groove 28 includes a first vertical groove 2801 and a first inclined groove 2802. A first guiding pin 29 is slidably disposed in the first vertical groove 2801. The first guiding pin 29 is fixedly connected to the first adjusting frame 20. The second guiding groove 30 includes a second vertical groove 3001 and a second inclined groove 3002. A second guiding pin 31 is slidably disposed in the second vertical groove 3001. The second guiding pin 31 is fixedly connected to the second adjusting frame 23. It should be understood that for the steel sheet pile body 34 that has been inserted, stability needs to be maintained. By adjusting the assembly, the second adjusting frame 23 and the first adjusting frame 20 are synchronously adjusted to move, so as to realize that the two second stabilizing plates 22 are tightly attached to two symmetric first surfaces 3401 in the concave surface of the steel sheet pile body 34, and the first stabilizing plate 19 is tightly attached to the second surface 3402 in the concave surface of the steel sheet pile body 34, and cooperate with the first pile stabilizing assembly to clamp and position the inserted steel sheet pile body 34;

[0054] Corresponding to the position of the pile to be driven, after adjusting the distance between the pile stabilizing body 16 and the first pile stabilizing assembly, the two second stabilizing plates 22 are adjusted to retract into the second receiving grooves 21 through the adjusting assembly, and the first stabilizing plate 19 is adjusted to retract into the first receiving groove 18. When the steel sheet pile body 34 to be inserted is inserted between the pile stabilizing body 16 and the second pile stabilizing assembly, while limiting and supporting the concave surface of the steel sheet pile body 34, through rolling support, friction is reduced, which is beneficial to stabilizing the driving direction of the steel sheet pile body 34 while reducing the frictional resistance to the driving of the steel sheet pile body 34.

[0055] The specific adjustment method of the adjustment component is as follows: By rotating the driving screw 36, the driving screw 36 will drive the moving frame 27 in a threaded manner. The moving frame 27 will synchronously drive the first guiding groove 28 and the second guiding groove 30 to move. During the upward movement of the moving frame 27, when the first vertical groove 2801 of the first guiding groove 28 moves to the first guiding pin 29, the second vertical groove 3001 of the second guiding groove 30 moves to the second guiding pin 31. At this time, the first stabilizing plate 19 and the second stabilizing plate 22 are respectively pushed by the first adjusting frame 20 and the second adjusting frame 23, so that the first stabilizing plate 19 and the second stabilizing plate 22 respectively move out of the first receiving groove 18 and the second receiving groove 21, and the first stabilizing plate 19 and the second stabilizing plate 22 are in a state where they can be attached to the concave surface of the steel sheet pile body 34;

[0056] When the moving frame 27 moves downward, when the first inclined groove 2802 of the first guiding groove 28 moves to the first guiding pin 29 and the second vertical groove 3001 of the second guiding groove 30 moves to the second guiding pin 31, at this time, the first stabilizing plate 19 and the second stabilizing plate 22 are respectively pulled by the first adjusting frame 20 and the second adjusting frame 23, so that the first stabilizing plate 19 and the second stabilizing plate 22 respectively retract into the first receiving groove 18 and the second receiving groove 21. The first pile stabilizing column 24 and the second pile stabilizing column 25 are in a state where they can be attached to the concave surface of the steel sheet pile body 34. During the driving process, rolling contact can be achieved, while stabilizing the driving direction of the steel sheet pile body 34, the frictional resistance can be reduced.

[0057] Specifically, a second adjusting head 32 is fixedly connected to the surface of the driving screw 36, which is convenient for the staff to rotate and adjust with the help of a wrench.

[0058] As Figure 1 and Figure 5 shown, in an embodiment, the second pile stabilizing component includes a plurality of pile stabilizing rollers 33. The plurality of pile stabilizing rollers 33 are rotatably connected to the third docking frame 4, and the plurality of pile stabilizing rollers 33 are all in contact with the convex end surface of the steel sheet pile body 34. It should be understood that under the limitation of the gap formed between the pile stabilizing roller 33 and the pile stabilizing body 16, both the convex end surface and the concave surface of the steel sheet pile body 34 can be supported, which is beneficial to maintaining the stability of the driving direction of the steel sheet pile body 34. And during the driving process, through the rolling support of the first pile stabilizing column 24, the second pile stabilizing column 25 and the pile stabilizing rollers 33, the frictional resistance to the steel sheet pile body 34 in the driving direction can be further reduced.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
