Lifting frame for bored pile in limited space

Abstract

The invention discloses a lifting frame for a bored pile in a limited space. The lifting frame comprises a fixed frame and a movable frame, wherein the fixed frame comprises four steel frames I whichare vertically arranged and arranged in a rectangular mode, the lower end of each steel frame I is connected with a set of moving wheels, the movable frame comprises four steel frames II which are vertically arranged and arranged in a rectangular mode, connecting supports connected among the four steel frames II and a cross beam connected to the upper ends of the four steel frames II, the outer side of the lower end of each steel frame II is fixedly connected with a sleeve, the four sleeves are movably arranged on the four steel frames I respectively in a sleeving mode, the movable frame is located in the fixed frame, a plurality of pin holes are formed in the steel frames I in the height direction of the steel frames I, pin holes are further formed in the sleeves corresponding to the pinholes in the steel frames I, and a pulley block is arranged at the top end of the movable frame, a hosting hook is connected to the lower portion of the pulley block, a hydraulic winch is arranged onthe lower portion of the movable frame, and an oil wire rope of the hydraulic winch is connected with the pulley block. The lifting frame is suitable for hoisting construction in a low, long and narrow environment.

Description

technical field [0001] The invention relates to a hoisting frame used for bored piles, in particular to a hoisting frame used for bored piles in a limited space, and belongs to the technical field of building construction. Background technique [0002] Bored pile reinforcement cage and conduit hoisting construction technology is a relatively mature technology, which is often used in pile foundation construction in the range of roads, railways, and civil buildings. During the construction of bored piles, the reinforcement cages and conduits of the bored piles need to be hoisted by the bored pile hoisting frame. The hoisting frame of the bored pile needs to be pulled and transported by vehicles such as cars. At present, drilling rig hangers are often used in construction for hoisting operations. [0003] When carrying out the construction of the fulcrum pile of the existing business line, due to the narrow, low and slender construction space, the existing drilling rig liftin...

AI Technical Summary

Problems solved by technology

[0003] When carrying out the construction of the fulcrum pile of the existing business line, due to the narrow, low and slender construction space, the existing drilling rig lifting frame is mostly vehicle-mounted with a height > 6m, and the frame is heavy and the height exceeds the pile foundation The allowable range of channel size, so it cannot be used for pile foundation construction under the beam
