Abstract
The utility model discloses a combined balance weight for an excavating machine, which comprises a main balance weight. The main balance weight is connected with an auxiliary balance weight through a bolt and a washer; and the auxiliary balance weight is connected with a lifting lug. By being additionally provided with the modular auxiliary balance weight, the defect that the main balance weight of the traditional excavating machine is dismantled to be replaced by a new balance weight is overcome; and the auxiliary balance weight produced by adopting a casting method has the advantages of compact structure and convenience in disassembly and assembly and is convenient to carry and mount the combined balance weight and as well as is convenient to adjust the weight of a balance weight body. The re-connection of the auxiliary balance weight and the balance weight of the traditional excavating machine achieves the requirements for improving the stability of the excavating machine and adapting to various work tools.
Description
Technical field
The utility model relates to a kind of excavator annex, relates in particular to the counterweight that a kind of excavator is used.
Background technology
The counterweight of known excavator, particularly box weld counterweight comprises the metal shell that is welded, and is filled with concrete and ore proportioning thing in the shell.Though this counterweight is simple in structure, because the difference of manufacture level or the variation of applying working condition, this counterweight exists the weight uniformity poor, the disadvantage that the incompatibility various working requires.In case it is light partially that excavator is in use found counterweight, then can cause pitching or the excavator unstability when excavating.After excavator had been changed the different work facility, counterweight was if replacing then faces very big assembling difficulty and transportation problem.
Summary of the invention
Exist the weight uniformity poor in order to overcome known excavator counterweight, the defective that the incompatibility various working requires, the utility model provides a kind of excavator combined type counterweight, and the weight high conformity of this excavator combined type counterweight can adapt to the various working requirement.
The technical solution of the utility model is: this combined type counterweight comprises main counterweight, is connected with auxiliary counterweight by bolt and packing ring above the main counterweight, is connected with hanger above the auxiliary counterweight.
Be provided with " protruding " shape location structure above the described auxiliary counterweight, be provided with " recessed " shape location structure below the auxiliary counterweight.
Main counterweight is connected with excavator turntable main body with packing ring by four bolts.Auxiliary counterweight is connected with the bolt hole of packing ring with main counterweight top by two bolts, and the two forms a whole.Auxiliary ligand is reseted and is counted a plurality of thin combinations of weights stacks, thereby the modularization that realizes auxiliary counterweight is used.The design of plane bolt mounting holes periphery has a small boss plane on the auxiliary counterweight, is convenient to the installation of bolt and fixing.The a pair of hanger on plane can be assemblied on the auxiliary counterweight of top on the auxiliary counterweight, is convenient to the lifting of this counterweight.
Main counterweight adopts the manufacturing of traditional welding filling mode, reduces cost.Auxiliary counterweight adopts the cast form manufacturing, accurately controls weight, reduces volume, is convenient to aggregate erection and dismounting.Versatility and convenience have been increased.
Advantage of the present utility model: by installing the auxiliary counterweight of modularized design additional, overcome the defective that needs the original excavator master counterweight of dismounting more to renew counterweight, the auxiliary counterweight that adopts casting method to make, has compact conformation, the advantage of easy accessibility, be convenient to the carrying and the installation of this combined counterbalance, also be convenient to the adjustment of balance weight body weight simultaneously.Reconnecting of auxiliary counterweight and original excavator counterweight reached the requirement that increases excavator stability and adapt to multiple work implements.
