AI Technical Summary

Technical Problem

Existing pile foundation positioning devices suffer from low stability due to uneven ground at construction sites, and cannot be adjusted according to actual construction needs and pile foundation dimensions, resulting in low positioning accuracy.

Method used

An adjustable U-shaped base and a hydraulic bidirectional cylinder are used in conjunction with a clamping platform. The longitudinal and lateral adjustments are made to adapt to pile foundations of different sizes. Rubber rollers and a chassis are added to improve stability and friction. A hydraulically controlled insertion rod extends to the ground surface to increase positioning accuracy.

Benefits of technology

The positioning device has been able to accurately adapt to pile foundations of different sizes, improving positioning accuracy and stability, avoiding positional deviation and tilting, and enhancing stability during construction.

Abstract

The utility model discloses an adjustable building pile foundation positioning device, and belongs to the technical field of building construction. A U-shaped base capable of being longitudinally adjusted according to the actual diameter of a pile foundation is matched with a clamping table capable of being transversely adjusted so that the positioning device can adapt to the pile foundations of different sizes, an arranged hydraulic bidirectional cylinder enables a dragging table to vertically adjust the clamping and positioning height according to the size of the pile foundation, and meanwhile an inserting rod is controlled to extend into soil; by matching with the chassis, on one hand, the contact surface with the ground is increased to avoid sinking, on the other hand, the stability of the device is improved, and on the other hand, rubber concave-convex surfaces are additionally arranged on the surfaces of the rollers for clamping the pile foundation to improve the clamping stability. Clamping assemblies are movably connected to the inner sides of the clamping tables, lifting type dragging tables are movably connected to the lower ends of the clamping tables, an adjustable U-shaped base composed of two symmetrical L-shaped surrounding edges and an extension piece is arranged at the bottoms of the two dragging tables, the lower end of a hydraulic bidirectional cylinder is connected with an insertion rod through a piston rod, and the upper end of the hydraulic bidirectional cylinder penetrates through the U-shaped base through the piston rod to be connected with the dragging tables.
