Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hydraulic impact hammer, concretely is a kind of hydraulic impact hammer anticorrosive shell. BACKGROUND

[0002] Hydraulic impact hammer belongs to impact pile driver, and can be divided into single-acting and double-acting according to its structure and working principle.The so-called single-acting is that the impact hammer core is released quickly after being lifted to a predetermined height by hydraulic device, and strikes pile body in free-fall mode.The double-acting is that the impact hammer core is lifted to a predetermined height by hydraulic device, and strikes pile body by obtaining acceleration energy from hydraulic system to improve impact speed.This also corresponds to two pile driving theories, and single-acting hydraulic pile driver corresponds to heavy hammer light hitting theory, with larger hammer core weight, lower impact speed and longer hammering time, so that the degree of penetration is large, and it is suitable for various shapes and materials of pile type, with low pile damage rate, especially suitable for driving concrete pipe pile.Double-acting hydraulic pile driver corresponds to light hammer heavy hitting theory, with smaller hammer core weight, higher impact speed and shorter hammering time, so that the impact energy is large, and it is most suitable for driving steel pile.However, the common hydraulic impact hammer on the market generally lacks a matching anticorrosive shell, which is not convenient for protecting the hydraulic impact hammer and affects the service life of the impact hammer, so an appropriate hydraulic impact hammer anticorrosive shell is needed to protect it.

[0003] The hydraulic impact hammer anticorrosive shell disclosed in the authorized announcement No.CN216339516U includes an impact hammer body, both sides of the impact hammer body are provided with mounting shells, the top of the impact hammer body is provided with a fixed plate, both sides of the bottom of the fixed plate are provided with first sliding grooves, the first sliding grooves are slidably connected with first sliding blocks, the top and the bottom of both sides of the impact hammer body are provided with limiting grooves, the center of the side away from the mounting shell is provided with a first threaded groove, and the first threaded groove is rotatably connected with a first threaded rod.The utility model covers the impact hammer body by setting the fixed plate and the mounting shell, limits the first sliding block by setting the first sliding groove, prevents the first sliding block from shaking during movement, limits the mounting shell by setting the first sliding block, prevents the mounting shell from shaking during movement, and limits the first threaded rod by setting the second threaded groove.However, the utility model has a complex structure, is inconvenient to install and disassemble, and lacks an anticorrosive layer, which is not convenient for protecting the anticorrosive effect of the shell, so we propose a hydraulic impact hammer anticorrosive shell to solve the installation and anticorrosion problems of the utility model, improve the use durability and installation convenience of the anticorrosive shell.
