Description

Technical Field

[0001] The utility model relates to a water construction device, in particular to a vertical pile lifter for assisting in lifting steel pipe piles. Background Technique

[0002] When carrying out water construction of steel pipe piles, the steel pipe piles need to be lifted and then construction processes such as pile driving are carried out. Due to the large length-diameter ratio of the steel pipe piles, during the single-point lifting process of the steel pipe piles, when the pile head is lifted, the pile tip that has not been lifted may slide due to pile lifting, and even cause the steel pipe pile to break. According to construction experience, a steel section frame can be welded on the barge deck to limit the pile tip therein. However, the conventional construction method uses a single-layer simple frame structure as a fixing measure, and the frame height is usually relatively low. In this structure, the pile tip may still slide out during pile lifting, posing a certain safety risk. Summary of the Invention

[0003] Purpose of the utility model: The purpose of the utility model is to provide a vertical pile lifter for assisting in lifting steel pipe piles, which can limit the displacement of the pile tip, improve stability and construction efficiency.

[0004] Technical solution: The vertical pile lifter for assisting in lifting steel pipe piles described in the utility model includes a horizontal rod and a longitudinal rod that form an overall U-shaped frame. The horizontal rod includes an upper horizontal rod and a lower horizontal rod. The upper horizontal rod includes an upper transverse rod and an upper vertical rod, and the lower horizontal rod includes a lower transverse rod and a lower vertical rod.

[0005] Preferably, a first longitudinal bracket is fixedly arranged between the upper transverse rod and the lower transverse rod to increase the stability and strength of the vertical pile lifter.

[0006] Preferably, a second longitudinal bracket is fixedly arranged between the upper vertical rod and the lower vertical rod to increase the stability and strength of the vertical pile lifter.

[0007] Preferably, both the horizontal rod and the longitudinal rod are made of steel sections.

[0008] More preferably, both the horizontal rod and the longitudinal rod are made of 26# H-shaped steel.

[0009] Preferably, the first longitudinal bracket is made of 40a channel steel.

[0010] Preferably, the second longitudinal bracket is made of 40a channel steel.

[0011] Beneficial effects: Compared with the prior art, the utility model has the following remarkable advantages: (1) During the on-water construction process of the steel pipe pile, when the pile head is lifted, the displacement of the pile tip can be restricted and support can be provided, and no slip will occur due to pile lifting; (2) It ensures that the steel pipe pile can be quickly and efficiently lifted within an effective working space, improving the construction efficiency; (3) The use of a double-layer structure for reinforcement can better prevent the pile tip from slipping out, and has extremely high stability and safety.

[0016] The technical solution of the utility model will be further described below in conjunction with the embodiments.

[0017] As shown in the figure, the vertical pile device for assisting in the lifting of steel pipe piles described in the utility model includes a horizontal rod 1 and a longitudinal rod 2 that form an overall U-shaped frame. The horizontal rod 1 includes an upper horizontal rod and a lower horizontal rod. The upper horizontal rod includes an upper transverse rod 11 and an upper vertical rod 12, and the lower horizontal rod includes a lower transverse rod 13 and a lower vertical rod 14.

[0018] A first longitudinal support 3 is fixedly arranged between the upper transverse rod 11 and the lower transverse rod 13 for increasing the stability and strength of the vertical pile device.

[0019] A second longitudinal support 4 is fixedly arranged between the upper vertical rod 12 and the lower vertical rod 14 for increasing the stability and strength of the vertical pile device.

[0020] Both the horizontal rod 1 and the longitudinal rod 2 are made of section steel.

[0021] Both the horizontal rod 1 and the longitudinal rod 2 are made of 26# H-section steel.

[0022] Both the first longitudinal support 3 and the second longitudinal support 4 are made of channel steel.

[0023] Both the first longitudinal support 3 and the second longitudinal support 4 are made of 40a channel steel.

[0024] The working principle of the pile erector of the utility model is as follows: the bottom of the pile erector is welded on the deck of the barge, and the bottom of the steel pipe pile is hoisted flatly into the groove of the U-shaped frame of the pile erector by a crawler crane, and the pile head of the steel pipe pile is hoisted. During the hoisting process, the staff should pay attention to observe so that the turning plane of the steel pipe pile is in the same plane as the crane wire rope. When the steel pipe pile is in a vertical state, the steel pipe pile is vertically hoisted, and the hoisting work of the steel pipe pile is completed.

[0025] During the lifting process, due to the presence of the pile erector, the pile tip of the steel pipe pile will not slip due to the pile lifting, ensuring that the steel pipe pile can be lifted quickly and efficiently within the effective working space, thereby improving construction efficiency; using a double-layer structure to reinforce the pile erector can better prevent the pile tip from slipping out, and has extremely high stability and safety.
