The counterweight device mainly comprises a counterweight main body, wherein a main body mounting groove, a counterweight block mounting groove and a filling hole are formed in the counterweight main body; the filling hole is sealed by a cover plate. The utility model discloses mainly used excavator different work condition counter weight's regulation.
Description
Technical Field
The utility model relates to an engineering machine tool, specifically speaking especially relates to an excavator counter weight.
Background
Most of the excavator balance weights are fixed after being assembled, and for some mine working conditions, the situation of accessory replacement, such as replacement between a breaking hammer and a bucket, often occurs, and under the situation that the accessories are different, the requirement on the stability of the whole excavator is different. The counterweight which can not change the weight brings limitation to the use of the accessory.
At present, a simple structure is lacking, the counterweight block is convenient to install, the counterweight block can be changed into counterweight blocks with different weights according to different working conditions, and the excavator counterweight with different requirements of the attachment of the working device on the stability of the whole excavator is met.
Disclosure of Invention
The utility model aims at providing an excavator counter weight to solve and lack a simple structure among the prior art, balancing weight simple to operate, the balancing weight can be changed the balancing weight of different weights according to different operating modes, satisfies the problem of the excavator counter weight of the different requirements of equipment accessory to complete machine stability.
The utility model discloses a realize through following technical scheme:
a counterweight of an excavator comprises a counterweight main body, wherein a main body mounting groove, a counterweight block mounting groove and a filling hole are formed in the counterweight main body; the filling hole is sealed by a cover plate.
Further, the mounting plate and the balancing weight are fixed on the balancing weight main body through bolts.
Further, the balancing weight mounting groove include left balancing weight mounting groove and right balancing weight mounting groove, the balancing weight includes left balancing weight and right balancing weight, be equipped with hoist and mount hook in the balancing weight mounting groove, be equipped with on left balancing weight and the right balancing weight and hang the cooperation groove that the hook shape is the same.
Further, the mounting plate and the balancing weight are welded together.
Further, the replacement weight of the balancing weight is 200kg-1200 kg.
Compared with the prior art, the beneficial effects of the utility model are that:
1. simple structure, the balancing weight is installed in counter weight main part top, and is more convenient during the installation.
2. The balancing weights can be changed according to different working conditions, different requirements of the attachment of the working device on the stability of the whole machine are met, and the weight adjusting range can reach more than one ton.
3. In general working conditions, only the counterweight main body can be used, so that the load of the whole machine is reduced, and the oil consumption is reduced; during heavy load operating mode, assemble the balancing weight to the counter weight, satisfy the operating mode requirement.
Drawings
Fig. 1 is an exploded view of the present invention;
fig. 2 is a schematic structural diagram of the present invention.
In the figure: 1. a counterweight main body; 2. a cover plate; 3. a balancing weight; 4. hoisting hooks; 5. mounting a plate; 7. a counterweight block mounting groove; 8. a main body mounting groove.
Detailed Description
The invention will be further described and illustrated with reference to the accompanying drawings.
Embodiment 1, an excavator counterweight includes a counterweight main body 1, the counterweight main body 1 is provided with a main body mounting groove 8, a counterweight block mounting groove 7 and a filling hole, a counterweight block 3 is arranged in the counterweight block mounting groove 7, and a mounting plate 5 is arranged on the counterweight block 3; the filling hole is sealed by a cover plate 2.
The utility model discloses a filling counter weight, apron 2 are the closed plate in the filling hole on the counter weight main part 1. During general operating mode, only use counter weight main part 1, reduce the complete machine load, reduce the oil consumption, counter weight mounting groove 7 can be used to provide the space of placing the hoist when the complete machine hoists this moment. During heavy load working condition, assemble balancing weight 3 and mounting panel 5 on counter weight main part 1 through the bolt, balancing weight 3 can be according to the excavator of different tonnages, and the design total weight is 200kg to 1200kg and varies for satisfy different tonnages, different working conditions are to the demand of counter weight. When the whole machine is required to be hoisted under the heavy-load working condition, the bolt is directly disassembled, and then the balancing weight 3 is disassembled, so that the whole machine can be hoisted without being influenced. Hoisting hook 4 has made things convenient for the hoist and mount in balancing weight mounting groove 7, hoists through hoisting hook 4 when installation counter weight main part 1, then installs counter weight main part 1 in the frame through main part mounting groove 8.
