Description

Electric pile driver

Technical Field

The utility model relates to an electric pile driver technical field specifically is an electric pile driver.

Background

The large pile driver consists of pile hammer, pile frame, auxiliary equipment, etc. The pile hammer is attached between two parallel vertical guide rods at the front part of the pile frame, commonly called as a gantry, and is hoisted by a hoisting hook. The pile frame is a steel structure tower frame, and a winch is arranged at the rear part of the pile frame and used for hoisting the pile and the pile hammer. The front of the pile frame is provided with a guide frame consisting of two guide rods for controlling the piling direction so that the pile can accurately penetrate into the stratum according to the designed direction. The basic technical parameters of the pile driver are the impact section weight, the impact kinetic energy and the impact frequency. The power source of the pile hammer according to the movement can be divided into a drop hammer, a steam hammer, a diesel hammer, a hydraulic hammer and the like.

Since large-scale piles are commonly used in construction sites, the columns are transported to a designated location by a hoisting device and then driven into the ground using a large pile driver. The common large-scale pile drivers include a drop hammer pile driver, a pneumatic hammer pile driver, a diesel hammer pile driver, a hydraulic hammer pile driver and a screw pile driver according to the power of the pile drivers.

The pile hammer of the pneumatic hammer pile driver consists of a hammer head and a hammer seat, takes steam or compressed air as power, and has two types, namely a single-acting pneumatic hammer and a double-acting pneumatic hammer. The single-acting pneumatic hammer uses a plunger or a cylinder as a hammer head, steam drives the hammer head to ascend, and then the hammer head is allowed to fall along a guide rod of a hammer seat to pile. The double-acting pneumatic hammer generally uses a weighted plunger as a hammer head and a cylinder as a hammer seat, and steam drives the hammer head to ascend and then drives the hammer head to downwards impact and pile.

The main body of the diesel hammer pile driver also comprises a cylinder and a plunger, the working principle of the diesel hammer pile driver is similar to that of a single-cylinder two-stroke diesel engine, and the hammer is driven to work by strong pressure generated by burning and exploding atomized diesel oil sprayed into a combustion chamber of the cylinder under high pressure and high temperature. The diesel hammer is divided into a guide rod type and a cylinder type according to the construction form. The guide rod type diesel hammer is pressed on the pile cap by taking a plunger as a hammer seat and lifted along two guide rods by taking a cylinder as a hammer head. The cylinder diesel hammer uses cylinder as hammer seat and is directly guided by the inner wall of lengthened cylinder barrel, two guide rods are omitted, and plunger is hammer head capable of moving up and down in cylinder

The hydraulic pile driver is started by diesel oil belt, and can regulate hydraulic pressure according to different soil qualities of stratum to reach proper impact force for pile driving. Spiral drivers are pile-driving devices which drive a drill rod drill bit to form a hole in an underground drilling machine through a power head.

In the afforestation, in order to protect trees, flowers and plants and the like therein, a guardrail is usually required to be arranged and needs to be driven into the soil, thereby achieving certain strength. The pile is usually driven manually in the prior art, the working efficiency is low in the mode, physical strength is consumed, and the implantation depth of the guardrail cannot be guaranteed.

Meanwhile, due to the adoption of a handheld piling mode, in use, a worker is required to have larger gripping capacity, and meanwhile, the electric pile driver needs to be kept vertical all the time, so that the electric pile driver is inconvenient to use and has larger limitation.
