A hydraulic fixture positioning base device for water steel piles

Abstract

The invention discloses a positioning base device of a steel pile hydraulic fixture on water, which belongs to the technical field of building construction. A hydraulic clamp positioning base device for steel piles on water, including a fixed base, two rotating shafts are symmetrically rotated on the inner side of the double-ear limit block, and the inner end of the rotating shaft extends through the inside of the double-ear U-shaped block to the outside and is sleeved with a worm gear , the upper and lower ends of the inner side of the rotating shaft are symmetrically socketed with two support rods. The front end of the hydraulic cylinder A extends through the through groove to the outside and is fixed with a clamping arc. The interior of the clamping arc is linear and equidistant with multiple arcs. The steel pipe pile is sandwiched between the two clamping arcs. The close fit between the structures makes the device clamp multiple points on the steel pipe pile by setting the upper and lower clamping arcs, so that it is in the same position as the bottom surface. Vertical state, and through the design of the hydraulic cylinder A, it can move forward and backward for positioning, which improves the efficiency of positioning, ensures the verticality of the steel pipe pile and the bottom surface, and avoids the disadvantages of traditional visual inspection.

Description

technical field [0001] The invention relates to the technical field of building construction, and more particularly, to a base device for positioning a hydraulic clamp of an aquatic steel pile. Background technique [0002] In construction, steel pipe piles are often driven by vibrating hammers, so that the steel pipe piles are inserted into the ground. In order to prevent the steel pipe pile from being deflected during the application, it is necessary to ensure that its position is accurate and vertical at the beginning of the application. In the prior art, equipment such as a crane and artificial eyes are usually used for operation, which has poor positioning effect, is prone to deflection, and has low efficiency and poor effect. [0003] In the existing pile clamping and positioning device, for example, CN213197177U relates to a steel pile supporting fixture, which uses hydraulic rods to realize the adjustment of a single position of the pile body, but for long-length pi...

Problems solved by technology

The existing technology is usually operated by cranes and other equipment and artificial naked eyes, the positioning effect is poor, deflection is easy to occur, and the efficiency is low and the effect is poor

[0003] In the existing pile clamping and positioning devices, for example, CN213197177U relates to a steel pile support fixture, which adopts a hydraulic rod to realize the adjustment of a single position of the pile body, but for a longer pile pile, multiple clamping mechanisms are required. Adjustment;

[0004] In addition, among other pile clamping and positioning devices, some use double clamping arc heads to enhance the stability of the pile correction process, and the same power drive mechanism is used between the two arc chucks to realize pile alignment. clamping, but the diameter of the pile in the actual operation scene is not constant, for example, some tapered bodies with gradual diameter changes, using the same power drive and transmission mechanism will cause one clamping head to clamp while the other clamping head still Without tight grip, the correcting effect of the double arc chuck cannot be fully exerted in some operation scenarios, while the simple use of an independently working electromagnetic rotary clutch has limited torque, and the purchase cost and maintenance cost are high
