[0023] When the pile driver is driving piles, a large amount of time is used for clamping the pile body, and the main problem in the clamping process of the pile body is to adjust the pile body from a horizontal state to a vertical arrangement below the pile cap. At present, the pile body is mainly adjusted by manually assisting the pile lifting mechanism, and for some pile bodies with a through hole in the middle, the guide assembly 80 is arranged on the clamping assembly, which can improve the clamping efficiency of the pile body during clamping. However, different construction requirements use different pile body structures, and for the pile body with a solid structure in the middle, the guide structure arranged cannot be applicable to the clamping requirements of this type of pile body. In order to solve the foregoing problem, the technical scheme shown in Figures 1-2 The utility model adopts the technical scheme shown in the figure to implement a pile driving equipment, which comprises a pile driver base 10, a pile driver frame 20 and a lifting mechanism 50 arranged vertically on the pile driver base 10, a pile clamp 40 for clamping the pile body and a pile hammer 30 assembly for driving the pile body into the ground arranged on the pile driver frame 20, the lifting mechanism 50 is used for lifting the pile hammer 30 assembly, the pile clamp 40 comprises a movable frame, a clamping assembly and a guide assembly 80 arranged on the lower part of the movable frame, the movable frame is vertically slidably arranged on the pile driver frame 20, the clamping assembly is used for forming a U-shaped clamping opening for clamping the upper end of the pile body downward, the guide assembly 80 is used for guiding the pile body during clamping to facilitate the vertical arrangement of the pile body, the guide assembly 80 is movably arranged and connected with an adjustable assembly, and the adjustable assembly adjusts the movement of the guide assembly 80 into and out of the U-shaped clamping opening.

[0024] Through the implementation of the above scheme, for the pile body clamping that needs to be guided by the guide assembly 80, the guide assembly 80 is moved into the U-shaped clamping opening through the adjustable assembly, and for the pile body clamping that does not need the guide assembly 80, the guide assembly 80 is adjusted to exit the U-shaped clamping opening. Through the implementation of the above scheme, different construction requirements can be met.

[0025] Further, the guide assembly 80 is movably arranged on the movable frame in the vertical direction. The guide assembly 80 is suspended on the mounting seat 72, and the mounting seat 72 is slidably arranged in the vertical direction. The movable frame includes an upper top plate and a lower bottom plate 61, and the upper top plate and the lower bottom plate 61 are connected by connecting columns. The lower bottom plate 61 is provided with a gap for the guide assembly 80 to move in and out of the U-shaped clamping opening. The movable adjusting assembly is arranged between the upper top plate and the lower bottom plate 61. The clamping assembly has an inverted conical outer contour, including a horizontally arranged mounting plate body and a first plate body and a second plate body fixedly arranged on the lower surface of the mounting plate body. The shapes of the first plate body and the second plate body are consistent with the pattern M. The first plate body and the second plate body are cross-shaped and arranged on the mounting plate body. The pattern M is an isosceles triangle or an isosceles trapezoid. The angle adjusting assembly is connected with the mounting plate body. The movable adjusting assembly is composed of a first adjusting oil cylinder 71. The guide assembly 80 is adjusted to rise and fall by the first adjusting oil cylinder 71. The adjustment is convenient and easy to operate, and does not affect the original pile driver structure. The cylinder body of the first adjusting oil cylinder 71 is mounted on the upper top plate, and the piston rod of the first adjusting oil cylinder 71 is connected with the mounting seat 72. A plurality of guide rods 73 are arranged between the upper top plate and the lower bottom plate 61, and the mounting seat 72 is slidably arranged on the guide rods 73.

[0026] Further, the guide assembly 80 is movably mounted on the mounting seat, the guide assembly 80 is connected with the angle adjusting assembly, and the angle adjusting assembly adjusts the inclination angle of the guide assembly 80. The guide assembly 80 is rotatably mounted on the mounting seat 72 through the first shaft body 77, and the angle adjusting assembly adjusts the rotation of the guide assembly 80 around the first shaft body 77.
