Description

Technical Field

[0001] This utility model relates to the field of pile driving equipment technology, specifically to a pile driver for on-site construction of water conservancy projects. Background Technology

[0002] Hydraulic engineering is a discipline that studies fluid flow and transport, primarily focusing on water and wastewater. It includes surveying, design, construction, and planning. Piling machines are essential for these activities. Existing piling machines suffer from the following problems: 1. Different application scenarios require varying piling depths and dimensions. However, existing devices cannot adjust these dimensions due to the fixed connection between the piling mechanism and other components, reducing practicality. 2. Piling typically requires lifting the pile hammer and relying on its descent to drive the pile into the ground. This method lacks the ability to quickly and repeatedly drive piles, resulting in low efficiency. 3. During piling, the piling machine's position shifts, affecting accuracy. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pile driver for on-site construction of water conservancy projects with adjustable pile depth and size, and high pile driving efficiency and accuracy.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A pile driver for on-site construction of water conservancy projects includes a base plate, a lifting mounting plate mounted on the base plate, and a pile driving mechanism mounted on the mounting plate. A caster wheel is provided at the bottom corner of the base plate, and a fixing mechanism is provided on one side of the caster wheel on the base plate. The fixing mechanism includes a support plate mounted on the bottom of the base plate via an automatic telescopic rod. A second through hole is provided in the middle of the support plate, and a first through hole corresponding to the second through hole is provided on the base plate. Fixing rods are provided within both the second and first through holes.

[0006] In one embodiment of this utility model, the piling mechanism includes a vertical plate fixedly mounted on a mounting plate, a turntable disposed on one side of the vertical plate, and a drive mechanism disposed on the other side of the vertical plate and connected to the rotating shaft of the turntable; a connecting shaft is fixedly disposed at the outer edge of the turntable, and a lifting rod is vertically disposed below the turntable, with a connecting rod hinged between the lifting rod and the connecting shaft; a support sleeve corresponding to the lifting rod is vertically disposed on the mounting plate, and the lower end of the lifting rod is connected to the pile head; a clearance groove is provided on the base plate directly below the pile head.

[0007] In one embodiment of this utility model, the upper end of the pile head is detachably connected to the lower end of the lifting rod via an installation rod; the pile head is equipped with various models depending on its weight and size.

[0008] In one embodiment of this utility model, a counterweight box is provided on the side of the base plate away from the relief groove. The counterweight box is provided with an inlet and an outlet. A viewing window and scale lines are provided on the side of the counterweight box.

[0009] In one embodiment of this utility model, the lower end of the fixing rod is conical and is inserted into the ground by hammering.

[0010] In one embodiment of this utility model, a guide mechanism is provided between the four corners of the base plate and the mounting plate, and a lifting mechanism is provided between the center of the base plate and the mounting plate. The guide mechanism includes a guide sleeve fixed to the base plate and a guide rod inserted into the guide sleeve. The upper end of the guide rod is fixedly connected to the mounting plate. The lifting mechanism is an electric screw or a hydraulic rod.

[0011] In one embodiment of this utility model, the fixing rod is a drill rod, which is inserted below the ground by a handheld drill; a mounting frame is provided on the outside of the guide sleeve, and a sliding sleeve corresponding to the guide sleeve is fixed on the mounting frame. A third through hole corresponding to the fixing rod is provided on the mounting frame, and the mounting frame is used to place the handheld drill.

[0012] In one embodiment of this utility model, the universal wheel is equipped with a brake pad; when the automatic telescopic rod is fully extended, the support plate is located below the universal wheel.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] The pile driver used in the on-site construction of the water conservancy project can adjust the height of the pile driving mechanism through a guiding mechanism and a lifting mechanism. The pile head is detachably mounted on the lifting rod via an installation rod, allowing for adjustment of the pile driving depth and dimensions according to actual requirements. Under the action of the turntable and the eccentrically mounted connecting shaft, the lifting rod enables continuous pile driving operations, greatly improving work efficiency.

[0015] After the base plate is moved into place by the casters, it is supported by the extension of the automatic telescopic rod, which makes the entire pile driver more stable. In order to prevent the pile driver from moving during operation, an extra-long fixing rod is inserted into the ground for fixation, which can avoid the position loss due to soft soil or other reasons, and greatly improve the pile driving accuracy.

Fixing rods 21 are provided in the second through hole 19 and the first through hole 101.

[0022] In this embodiment, the piling mechanism includes a vertical plate 6 fixedly mounted on the mounting plate 5, a turntable 7 disposed on one side of the vertical plate 6, and a drive mechanism 9 disposed on the other side of the vertical plate 6 and connected to the rotating shaft of the turntable 7. The drive mechanism 9 is a geared motor. A connecting shaft 8 is fixedly mounted on the outer edge of the turntable 7. A lifting rod 11 is vertically mounted below the turntable 7. A connecting rod 10 is hinged between the lifting rod 11 and the connecting shaft 8. The two ends of the connecting rod 10 are respectively hinged to the connecting shaft 8 and the upper end of the lifting rod 11. A support sleeve 12 corresponding to the lifting rod 11 is vertically mounted on the mounting plate 5. The lower end of the lifting rod 11 is connected to the pile head 14. A clearance groove 16 corresponding to the pile head 4 is opened on the bottom plate 1 directly below the pile head 14.

[0023] like Figure 2As shown, the upper end of the pile head 14 is detachably connected to the lower end of the lifting rod 11 via an installation rod 13.

[0024] A counterweight box 15 is provided on the base plate 1 on the side away from the clearance groove 16. The counterweight box 15 is provided with a water inlet and a water outlet, and a viewing window and scale lines are provided on the side of the box. The counterweight box 15 achieves its counterweight function by adding water, and the amount of water added is adjusted according to the weight of the pile head 14 to better ensure the overall stability of the pile driver.

[0025] A guide mechanism is provided between the four corners of the base plate 1 and the mounting plate 5, and a lifting mechanism is provided between the middle of the base plate 1 and the mounting plate 5.
