Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment of: the excavator comprises an excavator body 1, wherein one end of the excavator body 1 is movably connected with a balancing weight 2. One end of the excavator body 1 is fixedly connected with a positioning block 5. Two telescopic grooves 3 are formed in the excavator body 1. And a connecting mechanism 4 is arranged in the telescopic groove 3. The connecting mechanism 4 comprises an extension spring 8, and one end of the extension spring 8 is fixedly connected with the inner wall of the extension groove 3. The other end of the telescopic spring 8 is fixedly connected with a connecting rod 9, and the connecting rod 9 is L-shaped. The telescopic spring 8 is capable of exerting a force on the connecting rod 9 in the telescopic slot 3 away from the excavator body 1.

One end of the balancing weight 2 is provided with a connecting groove 6. The connecting groove 6 is matched with the positioning block 5. The connecting groove 6 can play a role in connecting and positioning the balancing weight 2 when the balancing weight 2 is installed. Two guide grooves 7 are formed in the balancing weight 2, and the guide grooves 7 are matched with the connecting mechanism 4. The guiding groove 7 comprises a compression section 15, a direction changing section 16 and a positioning section 10. The compression section 15 is located the upper end of guide groove 7, the lower extreme of compression section 15 is equipped with diversion section 16, the lower extreme of diversion section 16 is equipped with location section 10, location section 10 corresponds with the position of expansion tank 3. The guide groove 7 can guide the connecting rod 9 to move along with the movement of the balancing weight 2 when the balancing weight 2 is installed.

One side fixedly connected with gag lever post 11 of connecting rod 9, the one end swivelling joint of gag lever post 11 has revolving fragment 12. Limiting grooves 13 are formed in the two sides of the excavator body 1, and the limiting grooves 13 are communicated with the telescopic grooves 3. Clamping grooves 14 are formed in two sides of the excavator body 1, and the clamping grooves 14 are located above the limiting grooves 13. The clamping groove 14 is communicated with the limiting groove 13. The limiting groove 13 is matched with the limiting rod 11. The slot 14 is engaged with the rotary plate 12. When the rotary piece 12 is moved to the position of the slot 14, the position of the rotary piece 12 and thus the connecting rod 9 can be defined after the rotary piece 12 is screwed into the slot 14.

The working principle is as follows: earlier keep flat balancing weight 2, be connected the upper end of spread groove 6 on balancing weight 2 and the lower extreme of locating piece 5 on the excavator body 1 after that, place connecting rod 9 in 7 entrances of guiding groove, alright in order to begin the installation to balancing weight 2.

The counterweight block 2 moves along the direction of the guide groove 7, and the compression section 15 in the guide groove 7 can press the connecting rod 9, so that the connecting rod 9 moves towards the excavator body 1 in the telescopic groove 3. After the connecting rod 9 passes through the direction changing section 16 in the guide groove 7, the connecting rod 9 extends out towards the counterweight block 2 under the action of the telescopic spring 8. When location section 10 aligns with flexible groove 3, expanding spring 8 promotes connecting rod 9 in to location section 10 for connecting rod 9 stretches into location section 10, plays the effect of fixed balancing weight 2 positions.

When the counterweight block 2 needs to be removed, the limiting rod 11 is pulled firstly. The limiting rod 11 is pulled in the direction of the excavator body 1, and the connecting rod 9 can be driven to move in the direction of the excavator body 1. And then the connecting rod 9 is moved to the interface of the positioning section 10 and the direction changing section 16. The rotation piece 12 is screwed into the slot 14, so that the position of the rotation piece 12 can be limited, and the effect of limiting the position of the connecting rod 9 is achieved. After fixing the position of the connecting rod 9, the counterweight 2 is moved, and the connecting rod 9 is moved into the direction changing section 16 of the guide groove 7. The rotary piece 12 is then unscrewed from the slot 14, releasing the constraint on the connecting rod 9. Under the action of the extension spring 8, the connecting rod 9 enables the connecting rod 9 to enter the compression section 15 and push the connecting rod in the direction away from the excavator body 1. So that the connecting rod 9 can follow the change of the guide groove 7 in the guide groove 7. Finally, the connecting rod 9 is separated from the guide groove 7, and the disassembly of the balancing weight 2 is completed.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
