Detailed Description

The following are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model, which is further described with reference to the accompanying drawings and examples.

Example 1:

Referring to fig. 1-4, an excavator body 1 and a hoist assembly 2 are included.

The excavator body 1 is a miniature excavator structure, and can be seen by combining with the attached drawings, the excavator mainly comprises a main beam 3 and a movable arm connecting seat 4 arranged at the front end of the main beam 3. In actual use, the main beam 3 is one of the frame components of the excavator, the lower side of the main beam 3 is connected with the crawler belt 19 through the rotary seat 18, the front end of the main beam 3 is hinged with the movable arm assembly 20 through the movable arm connecting seat 4, and meanwhile, the action control is performed through the deflection oil cylinder arranged on the main beam 3. It should be noted that the rear end of the main beam 3 is generally provided with a counterweight 21, and the counterweight 21 can balance the weight of the boom assembly 20 at the front end. The center of gravity of the excavator body 1 can be approximately determined at the front of the main girder 3.

In this solution, the main girder 3 needs to be configured as a gooseneck structure, which includes a thickened portion 5 and an extension portion 6 connected in a gooseneck shape in front and back. The thickened portion 5 has a hollow rectangular structure in cross section, and the thickened portion can be used for the hydraulic oil pipe to pass in, so that the thickened portion is necessary.

The lifting appliance component 2 is arranged on the thickened part 5 of the main beam 3 and comprises a hammer fixing block 7, an upper fixing seat 8, a vertical lifting seat 9 and two shackles 10. Referring to the drawings, the hammer head fixing block 7 is of a T-shaped structure and is horizontally inserted into and fixedly connected with the thickened part 5 of the main beam 3. Specifically, one end of the hammerhead fixing block 7 with the hammerhead-shaped bulge is welded on the top side of the inner wall of the thickened part 5, and the other end extends outwards to the outside of the thickened part 5 through the gooseneck opening. Inside the main beam 3, gussets may be provided for reinforcement, welded to the side walls of the main beam 3 and the hammer head fixing blocks 7.

The upper fixing seat 8 is welded with the top surface of the thickened part 5 horizontally, and the hammer fixing block 7 is welded with the upper fixing seat 8. The rear part of the upper fixing seat 8 extends to the rear side of the thickened part 5 and is fixed with the hammer head fixing block 7, a plurality of welding holes 12 are formed in the upper fixing seat 8, the welding holes 12 are communicated with the hammer head fixing block 7 or the thickened part 5, and the welding holes 12 are welded with the hammer head fixing block 7 or the thickened part 5. This not only makes the weld-fixing at the edges, but also makes the reinforcement centrally.

As can be seen from the accompanying drawings, the rear part of the upper fixing seat 8 is provided with a mounting straight groove 17, and the vertical hanging seat 9 is inserted into the mounting straight groove 17 and is welded with the mounting straight groove 17. Thus, the vertical hanging seat 9 can be firmly and vertically fixedly arranged on the upper fixing seat 8, the upper part of the vertical hanging seat is provided with two mounting holes 11, and the two shackles 10 are respectively arranged through the plurality of mounting holes 11.

The shackle 10 is detachable and thus facilitates connection of the hook. For the purpose of stress balance, the two shackles 10 are respectively positioned at the left side and the right side of the vertical hanging seat 9, and the two shackles 10 are jointly connected with a main hanging ring 13. Such a connection also requires that the shackle 10 and the upright hanger 9 have only one degree of freedom of rotation to be adjusted, so that the shackle 10 comprises a U-shaped hooking member 14 and a connecting screw 15, the connecting screw 15 being inserted at both ends of the hooking member 14, and the free end being provided with a locking member 16 (nut), and the connecting screw 15 being inserted into the mounting hole 11. The shackle 10 is mounted in a manner that ensures that the lifting ring is centrally balanced rather than swayed during lifting.

The hoisting rigging is welded on the excavator body 1 for a long time, so repeated disassembly and assembly are not needed, and the hoisting can be carried out rapidly only by controlling the connection of the hook and the main hoisting ring 13 during hoisting, and the hoisting efficiency of equipment can be greatly improved.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
