Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation drivers, in particular to an underwater pile foundation driver. Background Art

[0002] An underwater pile driver is a device specifically designed for pile foundation construction in underwater environments. Its main function is to safely and effectively drive prefabricated piles into predetermined underground locations through the hammering action of a pile driver. Underwater pile foundation construction faces multiple challenges such as water flow, water depth, and bottom sediments. Therefore, the design of underwater pile drivers usually takes these factors into consideration to ensure smooth construction.

[0003] In the process of underwater piling, an underwater pile foundation driver is needed. Currently, most of the existing pile foundation drivers use hammer pile construction to hammer steel pipe piles into the foundation, although their pile driving speed is relatively fast.

[0004] However, the existing pile driver generates impact loads during the continuous hammering of steel pipe piles, which causes vibration and eccentric pressure at the pile head connection part, and easily causes the lower section of the pipe pile to deviate. The pile driving quality is poor, so an underwater pile driver is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides an underwater pile foundation driver, which solves the problem of poor pile delivery quality caused by the existing pile foundation driver, which generates impact loads in the process of continuously hammering steel pipe piles, causing vibration at the pile head connection part and resulting in eccentric pressure, which in turn easily causes the lower section of the pipe pile to be offset.

[0006] To achieve the above object, the present invention provides the following technical solution: an underwater pile driver, comprising a pile driver body and a pile driver pipe, wherein a stable pile pressing assembly is provided on the outside of the pile driver body;

[0007] The stable pile-pressing assembly includes a pile driver and a winch fixedly mounted on the top of the pile driver body, a pile driving barrel fixedly connected to the inner side of the pile driver body, a pressure plate fixedly connected to the bottom of the pile driving pipe, a pile cap fixedly mounted on the bottom of the pressure plate, a fixed guide grip fixedly connected to the outside of the pile driving pipe, a mounting plate fixedly mounted on the outside of the fixed guide grip, a sliding sleeve fixedly connected to the back side of the mounting plate, and a linear guide rail fixedly connected to the front side of the pile driver body.

[0008] Furthermore, the number of the linear guide rails is three, and the sliding sleeves are slidably connected to the linear guide rails.

[0009] Furthermore, the outer diameter of the pile cap is smaller than the inner diameter of the steel pipe pile, and the outer diameter of the pressure plate is larger than the inner diameter of the steel pipe pile.

[0010] Furthermore, a lifting lug is fixedly connected around the pile delivery pipe, a steel wire rope is wound and fixedly connected to the outside of the hoist, and a lifting hole is opened on the outer surface of the lifting lug.

[0011] Furthermore, a lifting hole is provided on the outer surface of the lifting ear, and a lifting ring is fixedly connected to the bottom end of the steel wire rope, and the lifting ring is hung on the lifting hole.

[0012] Furthermore, the left and right sides of the lifting ear are fixedly connected with reinforcing ribs, and the steel wire rope passes through the pile driver body.

[0013] Furthermore, a connecting plate is fixedly connected to the top of the pressing plate, and a rear end of the connecting plate is fixedly connected to the outer side of the pile delivery pipe.

[0014] Compared with the prior art, the present invention provides an underwater pile foundation driver with the following beneficial effects:

[0015] The underwater pile driver, by providing a stable pile-pressing assembly, can continuously press down the steel pipe pile through the pressure plate to achieve the pile-pressing effect. Compared with the currently available pile drivers, it does not generate impact loads when pressing piles, and will not cause vibration and eccentric pressure at the pile head connection part, so it will not cause the lower section of the pipe pile to deviate, and its pile driving quality is better.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figures 1 to 4 The underwater pile driver in this embodiment includes a pile driver body 1 and a pile driver pipe 2. A stable pile pressing assembly is provided on the outside of the pile driver body 1.

[0024] The stable pile-pressing assembly includes a pile driver 3 and a winch 4 fixedly mounted on the top of the pile driver body 1. A pile driving barrel 5 is fixedly connected to the inner side of the pile driver body 1. A pressure plate 6 is fixedly connected to the bottom of the pile delivery pipe 2. A pile cap 7 is fixedly mounted on the bottom of the pressure plate 6. A fixed guide grab 8 is fixedly connected to the outside of the pile delivery pipe 2. A mounting plate 9 is fixedly mounted on the outside of the fixed guide grab 8. A sliding sleeve 10 is fixedly connected to the back of the mounting plate 9. A linear guide rail 11 is fixedly connected to the front side of the pile driver body 1. When in use, the pile driver 3 can continuously apply a downward force to the pile delivery pipe 2 through the pile driving barrel 5 to push the pile delivery pipe 2 so that the pile cap 7 of the pile delivery pipe 2 enters the interior of the steel pipe pile and continuously presses down the steel pipe pile through the pressure plate 6 to achieve the effect of pile pressing.

[0025] During this period, when the pile delivery pipe 2 is continuously pressed downward, the sliding sleeve 10 fixed on the back of the mounting plate 9 will continue to slide on the outer surface of the linear guide rail 11 to limit the position of the fixed guide grip 8, thereby ensuring the verticality of the pile delivery pipe 2 to avoid displacement.

[0026] Compared with the currently available pile foundation drivers, it does not generate impact loads when driving piles, and will not cause vibration and eccentric compression at the pile head connection part, so it will not cause the lower section of the pipe pile to deviate, and its pile driving quality is better.

[0027] It should be noted that there are three sets of linear guide rails 11 , and the sliding sleeves 10 are slidably connected to the linear guide rails 11 .

[0028] It should be understood that the outer diameter of the pile cap 7 is smaller than the inner diameter of the steel pipe pile, and the outer diameter of the pressure plate 6 is larger than the inner diameter of the steel pipe pile.

[0029] Example 2:

[0030] See also Figure 1On the basis of embodiment 1, a lifting eye 12 is fixedly connected around the pile delivery pipe 2, and a steel wire rope 13 is fixedly connected to the outside of the winch 4. A lifting hole is opened on the outer surface of the lifting eye 12, and a lifting hole is opened on the outer surface of the lifting eye 12. The bottom end of the steel wire rope 13 is fixedly connected to a lifting ring 14, and the lifting ring 14 is hung with the lifting hole. The left and right sides of the lifting eye 12 are fixedly connected with a reinforcing rib plate. The steel wire rope 13 passes through the pile driver body 1. Through the cooperation of the winch 4, the steel wire rope 13, the lifting eye 12 and the lifting ring 14, when in use, the winch 4 is started to lift or lower the pile delivery pipe 2, thereby facilitating the precise positioning of the pile delivery pipe 2 to the top of the steel pipe pile. At the same time, the downward pressure position of the pile driving barrel 5 can also be positioned.

[0031] In addition, a connecting plate 15 is fixedly connected to the top of the pressing plate 6 , and a rear end of the connecting plate 15 is fixedly connected to the outer side of the pile delivery pipe 2 .

[0032] The working principle of the above embodiment is:

[0033] When in use, the winch 4 is started to lift or lower the pile delivery pipe 2, so that the pile delivery pipe 2 can be accurately positioned on the top of the steel pipe pile. At the same time, the downward pressure position of the pile driving barrel 5 can also be positioned. When the pile delivery pipe 2 is placed on the top of the steel pipe pile, the pile driver 3 is started to continuously apply a downward force to the pile delivery pipe 2 through the pile driving barrel 5 to push the pile delivery pipe 2, so that the pile cap 7 of the pile delivery pipe 2 enters the interior of the steel pipe pile and continuously presses down the steel pipe pile through the pressure plate 6 to achieve the effect of pile pressing. During this period, when the pile delivery pipe 2 is continuously pressed downward, the sliding sleeve 10 fixed on the back of the mounting plate 9 will continue to slide on the outer surface of the linear guide rail 11 to limit the position of the fixed guide grab 8, thereby ensuring the verticality of the pile delivery pipe 2 to avoid displacement.

In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
