Abstract

The invention discloses a civil engineering pile driver, which comprises a sliding rod, a balancing weight, a pile driving head, a radial bearing, a rotating shaft, a chain plate, an upper chain wheel, a lower chain wheel, a chain, a driving motor and a deflector rod, wherein the radial bearing is sleeved on the sliding rod, the balancing weight is fixedly arranged on one side of the radial bearing, the pile driving head is arranged at the lower end of the balancing weight, the rotating shaft is arranged on one side of the radial bearing, the chain plate is arranged on one side of the sliding rod, the upper chain wheel is arranged at the upper part of the chain plate, the lower chain wheel is arranged at the lower part of the chain plate, the upper chain wheel and the lower chain wheel are in transmission through the chain, the lower chain wheel is driven through. Compared with the prior art, the invention drives the lower chain wheel and the upper chain wheel to move through the driving motor, the balance weight block is lifted by utilizing the contact of the deflector rod on the chain and the rotating shaft, and when the deflector rod turns over the other side, the balance weight block freely falls down to pile.

Description

Civil engineering pile driver

Technical Field

The invention relates to civil engineering equipment, in particular to a civil engineering pile driver.

Background

The pile driver consists of a pile hammer, a pile frame, accessory equipment and the like. The pile hammer is attached between two parallel vertical guide rods (commonly called gantry) at the front part of the pile frame 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. The pile driver in the prior art is not flexible enough, and meanwhile, the toughness and hardness of the pile driving head of the pile driver are not enough, so that the pile driving head deforms in the pile driving process, the service life is short, and an improved space exists.

Disclosure of Invention

The present invention aims to solve the above problems and to provide a civil engineering pile driver.

The invention realizes the purpose through the following technical scheme:

the pile driving device comprises a sliding rod, a balancing weight, a pile driving head, a radial bearing, a rotating shaft, a chain plate, an upper chain wheel, a lower chain wheel, a chain, a driving motor and a deflector rod, wherein the radial bearing is sleeved on the sliding rod, the balancing weight is fixedly arranged on one side of the radial bearing, the pile driving head is arranged at the lower end of the balancing weight, the rotating shaft is arranged on one side of the radial bearing, the chain plate is arranged on one side of the sliding rod, the upper chain wheel is arranged on the upper part of the chain plate, the lower chain wheel is arranged on the lower part of the chain plate, the upper chain wheel and the lower chain wheel are in transmission through the chain, the lower chain wheel is driven through the driving motor, and the deflector rod is fixed on the chain and can be in contact with.

Further, the pile driving head is made of copper, iron, nickel, chromium, titanium, silicon, polystyrene and glass fiber.

Specifically, according to the weight ratio, the copper accounts for 5%, the iron accounts for 80%, the nickel accounts for 2%, the chromium accounts for 2%, the titanium accounts for 1%, the silicon accounts for 2%, the polystyrene accounts for 3%, and the glass fiber accounts for 5%.

The invention has the beneficial effects that:

the invention relates to a civil engineering pile driver, which is characterized in that a driving motor drives a lower chain wheel and an upper chain wheel to move, a deflector rod on a chain is contacted with a rotating shaft to lift a balancing weight, and when the deflector rod turns the other side, the balancing weight falls freely to drive piles.
