Combined balance weight for excavator

Abstract

The invention relates to the technical field of excavators, and discloses a combined balance weight for an excavator. The combined balance weight for the excavator comprises a balance weight body and a connecting plate mounted on the excavator, wherein the top of the connecting plate is provided with an inserting groove; the back of the balance weight body is provided with a groove; the balance weight body sleeves the connecting plate through the groove; the top of the inner wall of the groove is fixedly connected with a fixing plate in the horizontal direction; an inserting plate inserted into the inserting groove is formed in the bottom of the fixing plate; a row of threaded holes I in the front-back axial direction are formed in the inserting plate in the length direction of the inserting plate; and a row of through holes corresponding to the threaded holes I are formed in the front face of the connecting plate. According to the combined balance weight for the excavator provided by the invention, through the inserting plate and threaded rods I arranged on the balance weight body, when the balance weight body needs to be disassembled, the threaded rods I are rotated to be separated from the threaded holes I through threaded fit, and the threaded rods I are pulled out of the through holes to lift the balance weight body upwards, so that the balance weight body is disassembled from the connecting plate, and the balance weight body can be conveniently disassembled and assembled on the excavator.

Description

technical field [0001] The invention belongs to the technical field of excavators, in particular to a combined counterweight for an excavator. Background technique [0002] An excavator, also known as an excavating machine, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. [0003] The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator are: operating weight (mass), engine power and bucket capacity. [0004] Common excavator structures include power devices, working devices, slewing mechanisms, operating mechanisms,...

AI Technical Summary

Problems solved by technology

[0005] The function of the counterweight of the excavator is to balance the whole vehicle. As the weight of the whole machine increases, the size and weight of the counterweight will also increase. On large mining excavators, the counterweight used can reach dozens of tons, while the existing The counterweight and the excavator are generally connected by welding, resulting in low disassembly efficiency of the counterweight and poor positioning accuracy, and it will be very cumbersome to replace the counterweight. Therefore, a combined excavator is designed. It is necessary to use counterweight to solve this problem
