Heavy hammer for excavating rock formation and welding processing method

Abstract

The invention discloses a heavy hammer for excavating a rock formation. The heavy hammer is characterized by comprising a heavy hammer body, wing plates and a heavy hammer appendage, wherein the heavy hammer body is an integral steel plate; and two pairs of wing plates are added at the tail part of the heavy hammer body, so that the phenomenon that turbulence from the wall of a slotted hole enables the heavy hammer to be tilted when the heavy hammer drops can be overcome, directional striking is realized, the quality of the slotted hole is guaranteed; and four wing plates and the heavy hammer body are symmetrically welded, so that a guiding function is achieved; holes for steel ropes to achieve hoisting are formed in the upper part of the heavy hammer body, concaves formed by colliding and cracking of rock are formed in the front side of the heavy hammer body, and an abrasion-resistant alloy is bead-welded to the concave position for enhancing the abrasion resistance; and two vertical plates are welded on the heavy hammer body, the heavy hammer appendage is welded to the heavy hammer body, and a baffle is welded to the heavy hammer body and used for preventing crushed blocks and uncrushed blocks from flying out when the heavy hammer crushes the rock, and the rock is further crushed until the rock can be lifted. The strength of a hammer head is guaranteed, and at the same time, by means of a special design of the hammer body, shaping recovery of the whole hammer can be guaranteed during striking. Directional striking can be achieved when the hammer strikes the rock formation, so that the working efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to a heavy hammer, in particular to a heavy hammer welding processing method for excavating special rock formations. Background technique [0002] my country's hydropower resources are very rich, especially concentrated in the western region. Due to the large altitude difference and abundant water, our province is known as the "land of a thousand waters", so the utilization of hydropower resources is particularly important. According to research, the hydropower resources in western China account for 57% of the country's total hydropower resources. At the same time, Tibet, Sichuan and Guizhou alone account for 43% of the country's hydropower resources and 8.2% of the world's. [0003] Although my country is rich in hydropower resources, the rationally utilized hydropower resources only account for 27% of the total energy. However, the geographical environment of most watersheds is complex and the construction is extremely diffic...
