Frame body of pile driver for civil engineering

Abstract

The present invention discloses a frame body of a pile driver for civil engineering, comprising a chassis. Side brackets are fixedly mounted on both sides of the top of the chassis, respectively; a top frame is fixedly connected to the tops of the side brackets; support plates are fixedly mounted on both sides of the top of the top frame, respectively; a roller is provided at the top of the top frame; rotation shafts are fixedly connected to both ends of the roller, respectively; the two rotation shafts are rotatably connected to the two support plates, respectively; two guide frames are fixedly mounted at the bottom of the top frame; guide blocks are slidably connected to the inner sides of the two guide frames; and pile driving rods are fixedly mounted at the bottoms of the guide blocks.In the present invention, wedge blocks are used for driving two poking forks to poke two sleeve shafts to leave away from the roller, so that the guide blocks automatically fall down; then, air spring support rods are used for pushing sleeve discs to close with convex discs to lift the guide blocks again; and the operations are repeated, so that the actual time of hammer lifting and hammer dropping is shortened, and the actual efficiency of pile driving is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a civil engineering piling frame body. Background technique [0002] The pile driver is composed of a pile hammer, a pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) at the front of the pile frame, and is lifted by a lifting hook. The pile frame is a steel structure. The tower frame is equipped with a winch at its rear, which is used to lift piles and pile hammers. Drop hammer pile drivers are composed of pile hammers, pile frames and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods at the front of the pile frame, and is hoisted with a lifting hook. The pile frame is a steel structure tower frame, and a winch is installed at the rear to lift the pile hammer; [0003] The prior art has the following deficiencies: in some small construction sites, s...

Problems solved by technology

[0003] The prior art has the following deficiencies: in some small construction sites, small pile drivers are used to facilitate the construction of some smaller pile bodies. After releasing the piling, it is necessary to reconnect the pile hammer and the hook, which greatly wastes the piling time and reduces the piling efficiency
