Abstract
The utility model aims at providing a pile hammer for highway guardrail installation, include: nitrogen chamber, cylinder body, piston, striking seat, uide bushing, striking head, shelves round pin, pile cap etc.. The hydraulic driving piston reciprocates in the cylinder body to strike the striking head and the pile cap, so that the middle-short piles are driven into the soil layer, and the hydraulic driving device has the characteristics of large impact force, high efficiency and low failure rate.
Description
Technical Field
The utility model relates to a pile driving device, more precisely, is a pile hammer for highway guardrail installation.
Background
In recent years, the hydraulic pile hammer is rapidly applied to the aspects of high-speed railways, highway soft foundation treatment, sea filling, bridge and wharf engineering, deep foundation pit support, foundation treatment of common buildings and the like. The equipment adopts a hydraulic power station as a hydraulic power source, and high-frequency vibration is generated through a vibration box to drive a pile body into a soil layer, so that the equipment is particularly suitable for short and medium pile projects such as municipal administration, bridges, cofferdams, building foundations and the like.
The existing pile driving device still has some defects when in use, although the pile driving device can complete the common pile driving task, the structural size of the pile driver is large, and if a small pile driver is adopted, the phenomena of small driving force and low efficiency exist.
However, in some places, such as the piling of guard railings on both sides of a road, a piling device with compact structure, large hitting force and high frequency is required, so that the piling device is convenient to construct in special terrains.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a pile hammer for highway guardrail installation adopts the hydraulic drive piston to be reciprocating motion in the cylinder body, hits the impact pile head, with well short pile drive into the soil layer, have that the impact force is big, efficient, the fault rate is low characteristics.
The utility model aims at realizing through the following technical scheme:
a pile driving hammer for installation of a road guardrail comprising: nitrogen chamber, cylinder body, piston, striking seat, uide bushing, striking head, shelves round pin, pile cap etc..
The nitrogen chamber is used for improving the impact energy of the piston striking head.
The utility model discloses further set up, piston reciprocating motion in the cylinder body, strike the head, for realizing this strike function, this structure cavity of resorption is normal high pressure, and the epicoele is intermittent type nature high pressure, because the area that epicoele hydraulic oil acted on the piston is greater than the area that cavity of resorption hydraulic oil acted on the piston, along with the pressure variation of epicoele, reciprocating motion is realized to the piston, strikes the head.
The utility model discloses the strike seat that sets up is used for the installation to strike the head, strikes the seat in order to protect, strikes the head and strikes between the seat, and the uide bushing of setting plays guiding orientation's effect to change after the fitting surface wearing and tearing, shelves round pin is used for striking spacing of head.
Since energy is derived from energy stored by hydraulic energy and nitrogen compression when the piston strikes the striking head, impact energy is large.
The utility model discloses adopt taper fit between the pile cap that sets up and the striking head, convenient to detach like this, the pile cap sets up the annular face and the square locating surface of the stake location of being convenient for in addition.

Figure 2 shows a construction of the pile cap.
Detailed Description
A pile driving hammer for installation of a road guardrail comprising: nitrogen chamber 1, cylinder body 2, piston 3, striking seat 4, uide bushing 5, shelves round pin 6, striking head 7, pile cap 8 etc..
The utility model discloses nitrogen chamber 1 that sets up is used for storing nitrogen gas, and piston 3 compresses nitrogen gas under the effect of cavity hydraulic oil thrust down, stores the energy, and when piston 3 impacted striking head 7, the release improves the impact energy that piston 3 struck striking head 7 because nitrogen gas is compressed the energy of storing.
The utility model discloses further set up, piston 3 reciprocating motion in cylinder body 2, strike head 7, for realizing this strike function, this structure cavity of resorption is normal high pressure, and the epicoele is intermittent type nature high pressure, because the area that epicoele hydraulic oil acted on piston 3 is greater than the area that cavity of resorption hydraulic oil acted on piston 3, along with the pressure change of epicoele, piston 3 realizes reciprocating motion, strikes head 7.
The utility model discloses strike seat 4 that sets up is used for installing and strikes head 7, strikes seat 4 in order to protect, strikes head 7 and strikes between seat 4, and the uide bushing 5 of setting plays guiding orientation's effect to change after the fitting surface wearing and tearing, shelves round pin 6 is used for striking the spacing of head.
Since energy is derived from energy stored by hydraulic energy and nitrogen compression when the piston strikes the striking head 7, impact energy is large.
The utility model discloses adopt taper fit between pile cap 8 and the striking head 7 that set up, convenient to detach like this, pile cap 8 sets up the annular face an and the square locating surface b of the stake location of being convenient for in addition.
