Embodiment 1

[0039] See attached figure 1 , a pile connector, including a fixed guide seat 2 connected with a replacement pile driver body 1 through a flange, combined with an attached figure 2 , the fixed guide seat 2 is a circular platform structure, the fixed guide seat 2 is coaxially fixed with a tubular structure main shaft 3, the main shaft 3 runs through the fixed guide seat 2, and the surface of the main shaft 3 forms a wear-resistant and corrosion-resistant chrome-plated layer by chrome plating. The end of the main shaft 3 away from the fixed guide seat 2 is sleeved with a movable guide seat 5 that slides along the axial direction of the main shaft 3. The movable guide seat 5 is also a circular platform structure, and the smaller ends of the fixed guide seat 2 and the movable guide seat 5 are close to each other. The side of the fixed guide seat 2 far away from the movable guide seat 5 is fixedly provided with an oil cylinder 4 through a flange, and the piston rod of the oil cyli...

Embodiment 2

[0044] An alternate pile driver, comprising an alternate pile driver main body 1, the lower end of the alternate pile driver main body 1 is provided with the pile connector in embodiment 1, the principle of the fixed guide seat 2 of the pile connector is that one side of the movable guide seat 5 is connected with the alternate pile driver by the flange The lower end is fixedly connected.

[0045] The working principle of this embodiment is: during the piling process, the impact force of the piling hammer is buffered and evenly transmitted to the pipe piles to avoid damage to the pipe piles. A stable connection is achieved between the alternate pile driver and the pipe pile through the pile connector, which can ensure the coaxiality of the pipe pile and the alternate pile driver during piling, and ensure the construction accuracy of the pipe pile. Simultaneously, the present invention can quickly and conveniently pull out the drilled pipe piles by pulling upwards for piling und...

Abstract

The invention relates to the technical field of seabed pile foundation construction equipment, in particular to a pile splicing device which comprises a fixed guide seat, a tubular main shaft is fixedly arranged on the fixed guide seat, an oil cylinder is fixedly arranged on the fixed guide seat, the piston rod end of the oil cylinder penetrates through the main shaft and is fixedly connected with a movable guide seat, and the movable guide seat is in sliding fit with the main shaft; a plurality of pairs of guide grooves with inclined bottoms are formed in the fixed guide seat and the movable guide seat, and a tensioning plate is embedded in each pair of guide grooves and is in sliding fit with the bottoms of the guide grooves. According to the pile splicing device, tight connection can be formed through the tensioning plates and a pipe pile, the construction precision of the pipe pile is guaranteed, and the driven pipe pile can be conveniently pulled out. The invention further provides a pile replacing device using the pile splicing device.

Description

technical field [0001] The invention relates to the technical field of submarine pile foundation construction equipment, in particular to a pile connector and an alternate pile driver using the pile connector. Background technique [0002] In the construction of marine engineering such as cross-sea bridges, pile foundation construction is a sub-project with high difficulty and high cost. In order to adapt to the special construction conditions of the ocean, pipe piles are commonly used in the construction of submarine pile foundations. The instantaneous explosive force during the working process of the piling hammer is very large. It is necessary to use a substitute piling driver to evenly transmit the force on the piling hammer to the pipe piles to avoid damage to the pipe piles. [0003] The utility model patent whose existing authorized notification number is CN204418182U discloses a kind of alternate pile driving, including pile top seal, force application section, lift...
