Abstract
The invention discloses a pile driver supporting arm convenient to install. The pile driver supporting arm convenient to install comprises a supporting arm body. The middle of the bottom face of the supporting arm body is concave inwards. The section of the supporting arm body is in a sickle shape. Lug grooves are formed in the two ends of the supporting arm body and provided with a first lug shaft and a second lug shaft respectively. The first lug shaft and the second lug shaft are perpendicular to the corresponding lug grooves. The supporting arm body is provided with a weight reduction groove, and a plurality of weight reduction holes are formed in the weight reduction groove. The diameters of the weight reduction holes are decreased gradually from the middle to the two sides. The pile driver supporting arm convenient to install can meet the use requirement, is simple in structure, convenient to install and low in machining cost, and meets the development requirement for miniaturization and lightweight of pile drivers.
Description
Technical field
The present invention relates to engineering machinery field, being specifically related to a kind of pile driver with being convenient to installing type support arm.
Background technology
Support arm is one of component the most key on pile driver, and the height of the structural strength of support arm directly affects the application life of pile driver.Traditional most complex structure of pile driver support arm, volume are heavy, and dismounting difficulty, not only makes processing and manufacturing cost higher, and are unfavorable for pile driver miniaturization in the future, light-weighted development prospect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of pile driver with being convenient to installing type support arm, this support arm structure is simple, is convenient to install, and processing cost is low and be beneficial to pile driver miniaturization, light-weighted demand for development.
