DETAILED DESCRIPTION

[0013] The technical solutions of the present application will be described clearly and completely below in combination with embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of protection of the present application.

[0014] Referring to Figures 1-8 , the present application provides a technical solution: Embodiments As Figures 1-8 shown, a pile supporting, erecting and driving device comprises a carrier vehicle 1, a support arm 2 arranged on the carrier vehicle 1, a pile supporting and erecting assembly 3 and a pile driving assembly 4 arranged on the support arm 2 in sliding manner. The support arm 2 is connected to the carrier vehicle 1 through a connecting arm and two hydraulic cylinders (the support arm 2 is hinged to the hydraulic cylinders and the connecting arm), which facilitates adjustment of the angle of the support arm 2 and folding and unfolding of the support arm 2. The structure is prior art, and the specific structure and working principle will not be described here.

[0015] The pile supporting and erecting assembly 3 is arranged directly below the pile driving assembly 4, and is used for clamping a wooden pile and fixing the wooden pile to stand at a pile driving point. The pile driving assembly 4 is free-falling after moving to a high point of the support arm 2, and drives the wooden pile into the pile driving point to a specified depth in an impact manner.

[0016] The support arm 2 is provided with a pulley block 5, the carrier vehicle 1 is provided with a winch 6, the pulley block 5 is provided with a steel rope 7, one end of the steel rope 7 is connected to the pile driving assembly 4, and the other end of the steel rope 7 is connected to the winch 6. The pile driving assembly 4 is driven to move vertically along the support arm 2 in a reciprocating manner through the steel rope 7.

[0017] As Figures 1-3 shown, the pile supporting and erecting assembly 3 comprises a first clamping jaw 8 and a second clamping jaw 9 rotatably arranged on a bracket, and the first clamping jaw 8 and the second clamping jaw 9 are driven to rotate by a pneumatic cylinder 10 to close or open the first clamping jaw 8 and the second clamping jaw 9.

[0018] The two pile supporting and erecting assemblies 3 are sequentially arranged along the length direction of the support arm 2 and are connected by the stand column 11.

[0019] As shown in FIG. 1, Figures 4-8 The pile driving assembly 4 includes a lifting mechanism and a knocking hammer 12, the knocking hammer 12 is provided with a connecting rod, the connecting rod is slidably connected with a slide rail provided on the support arm 2 through a first sliding seat 13, and the top end of the connecting rod is provided with a hook 20. The lifting mechanism is slidably connected with the slide rail through a second sliding seat 14, the top end of the lifting mechanism is connected with the steel wire 7, and the lifting mechanism is used for automatically unhooking after lifting the knocking hammer 12 to a high point by hooking, so that the knocking hammer 12 freely falls to knock the wood pile.

[0020] The lifting assembly includes a lock disc 15, a lock catch 16 and an unhooking box 17 (wherein the unhooking box 17 is a rectangular shell structure with an upper and lower opening), the lock disc 15 (which is horseshoe-shaped) is provided with a lock groove, the middle part of the lock catch 16 is rotatably connected with the lock disc 15, and one end of the lock catch 16 is provided with a clamping hook which cooperates with the lock groove to lock the hook 20. The other end of the lock catch 16 is connected with a reset spring 18. When the lifting assembly rises to a high point of the support arm 2, the lock catch 16 penetrates through the unhooking box 17 and rotates to release the hook 20 under the action of the unhooking box 17.

[0021] The lock catch 16 is a hammer-shaped structure, the lock catch 16 is provided with an unhooking driving column 21, the side wall of the unhooking box 17 is provided with an unhooking rail 22, the unhooking rail 22 includes a straight line segment and an arc segment, the straight line segment is communicated to the bottom of the unhooking box 17 for guiding the unhooking driving column 21; The arc segment is concentrically arranged with the rotation center of the lock catch 16, and is used for rotating the lock catch 16 by the unhooking driving column 21. Wherein, the lock catch 16 is rotatably connected with the lock disc 15 through a rotating shaft 19, and the rotation center of the lock catch 16 is the axis of the rotating shaft 19.

[0022] Working principle: (1) lifting: the winch 6 drives the steel wire to go down, so that the squeezing clamping hook of the knocking hammer 12 at the lower end rotates, and then the lock catch 16 is rotated to open the lock groove, at this time the hook 20 enters the lock groove, and after the hook 20 enters the lock groove, the lock catch 16 is reset under the action of the reset spring 18 (one end of the reset spring 18 is fixed with a bolt on the lock disc 15, and the other end is fixed with a bolt on the lock catch 16).

[0023] After the hook 20 is fixed, the winch 6 drives the steel wire 7 to be recovered, and then drives the knocking hammer 12 to go up, and stops when the knocking hammer 12 goes up to the lock box and the lower end of the unhooking box 17 contacts. The purpose of this step is to make room for the wood pile.

[0024] (2) wood pile clamping: the piston rod of the air cylinder 10 is extended to drive the first jaw 8 and the second jaw 9 to open, so that the distance between the first jaw 8 and the second jaw 9 can accommodate the wood pile, after the wood pile enters the opening of the first jaw 8 and the second jaw 9, the piston rod of the air cylinder 10 is retracted to close the first jaw 8 and the second jaw 9 to clamp the wood pile (preferably clamping the lower part of the wood pile, reserving the position for subsequent pile driving).

[0025] (3) pile driving: after the wood pile clamping is completed, the carrier vehicle 1 moves to the pile driving point, so that the lower end of the wood pile is aligned with the pile driving point. Then the winch 6 continues to drive the steel wire 7 to be retracted, and the knocking hammer 12 and the locking disc 15 continue to move upwards. When the locking disc 15 enters the unhooking box 17, the unhooking driving column 21 first enters the straight line segment of the unhooking track 22, and is guided by the straight line segment. When the unhooking driving column 21 enters the arc segment from the straight line segment, the unhooking driving column 21 moves along the arc segment, and the locking buckle 16 rotates under the action of the unhooking driving column 21 and the arc segment, thereby rotating the hook to release the hook 20.

[0026] After the hook 20 is released, the knocking hammer 12 falls freely under the action of gravity, and the knocking hammer 12 strikes the top of the wood pile when it moves downward, thereby achieving pile driving. Repeating this operation can drive the wood pile into the specified depth.

[0027] The pile driving assembly can automatically hook and unhook through the setting of the lifting mechanism, so as to ensure that the knocking hammer automatically drives the pile.

[0028] The above description is only the preferred embodiment of the present application, and it should be understood that the present application is not limited to the form disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein by the above-mentioned teaching or related art or knowledge.
