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. 1-6, includes a pair of hoist blocks 1, a pair of horizontally extending beams 12, and an i-shaped hoist 2.

The miniature excavator adopted in the embodiment is the existing equipment, the left side and the right side of the chassis of the miniature excavator are provided with the crawler frames 23, and the crawler frames 23 are used for installing riding wheels and crawlers; a blade 24 is provided on the front side of the machine. The hoisting stress points of the hoisting tool in the scheme are positioned on the crawler frame 23 and the bulldozer blade 24.

In this embodiment, the lifting base 1 is fixedly disposed on the left and right sides of the crawler frame 23 of the excavator by screwing or welding, and is located at the rear portion away from the blade 24. It can be seen from the attached drawings that the lifting seat 1 needs to extend out of the crawler belt, and the top of the lifting seat is provided with a hole. The lifting seat 1 can be quickly connected with and detached from the I-shaped lifting appliance 2, so that the lifting appliance is convenient to install.

A pair of horizontally extending beams 12 are removably disposed on the left and right sides of a blade 24 at the front of the excavator, respectively, and are horizontally extending. As can be seen in the figures, a connecting frame 16 is provided on the back side of the blade 24, and the connecting frame 16 is secured to the horizontally extending beam 12 using a securing pin. The horizontal extension beam 12 can be used as a wheel axle for carrying and walking of the mini excavator, and can also be used as a connecting point of a lifting appliance. In other embodiments, if the horizontally extending beam 12 is not provided, it is directly suspended from the blade 24.

The i-shaped spreader 2 comprises a central beam 3 and suspension assemblies 4 symmetrically arranged on the left and right sides of the central beam 3. The middle part of the suspension assembly 4 is fixedly connected with the central beam 3, thus resembling an i-shape.

The central beam 3 needs to be connected to the hook 6 of the crane. The central beam 3 comprises a vertical beam 13 which is vertically arranged, and a right angle beam 14 which is fixedly connected with the vertical beam 13 and is buckled on the upper side of the vertical beam 13. Wherein, the center of the vertical beam 13 is provided with a hanging hole 5 for hanging the hanging hook 6. The cross section of the right-angle beam 14 is a right-angle shape with two straight sides extending obliquely downward. In order to further improve the strength, diagonal beams 15 for connection with the right angle beams 14 are provided on both front and rear sides of the vertical beams 13. As can be seen in connection with the figures, the crane hook 6 can be inserted into the lifting hole 5 to complete the connection.

The suspension assembly 4 is used for connecting the hoisting seat 1 and the horizontal extension beam 12 on the excavator. The suspension assembly 4 comprises a connecting piece 7 fixedly connected with the cross beam, and a first tension arm 8 and a second tension arm 9 which are respectively connected to the front side and the rear side of the connecting piece 7 through two shackles 22. Referring to the drawings, the connecting piece 7 is a right-angle bent plate, the right-angle part of the connecting piece is fixedly buckled on the right-angle beam 14, and the front end and the rear end of the connecting piece are respectively provided with through holes for connecting the shackle 22.

The second tension arm 9 is a straight connecting rod, the upper part of which is provided with a straight line hollow through which the shackle 22 penetrates, and the lower part of which is hinged with the shackle 22. The straight line fretwork is movably connected with the through hole of the connecting piece 7 through two connected shackles 22, the upper part of the lifting seat 1 is hinged with one shackles 22, and the lifting seat 1 and the second tension arm 9 are movably connected through the shackles 22 which are connected with the shackles 22 at the lower part of the second tension arm 9.

In order to facilitate the overall stability of the spreader, the length of the first tension arm 8 is set to be adjustable. Specifically, in this embodiment, the first tension arm 8 is a ratchet strainer, so as to implement tensioning of the lifting appliance. With reference to the figures, the first tension arm 8 has a central screw 18 provided with a ratchet 17, an adjusting handle 19 and two screws 20. Both ends of the screw 20 are provided with hanging rings 11 and have opposite threads. The center screw sleeve is simultaneously screwed with the two screws 20, and the relative distance between the two screws 20 can be changed by rotating the center screw sleeve. And the adjusting handle 19 is internally provided with a ratchet 21 matched with the ratchet wheel 17 and can rotate relative to the central screw cylinder 18. Thus, the first tension arm 8 can be tensioned by rotating the handle.

The two hanging rings 11 of the first tension arm 8 are respectively provided with a pair of shackles 22, and the lower ends of the hanging rings are connected with a drag hook 10. The retractor 10 can be hooked with the horizontally extending beam 12 as shown, so that the lifting can be completed.

It can be seen that the device has good flexibility of use and can be quickly connected and disconnected by the shackle 22. The shackle 22 includes an arcuate portion and a pin portion. The two ends of the arcuate portion are connected by this pin joint so that a plurality of shackles 22 can be connected or disconnected.

The device can rapidly and conveniently finish hoisting, and meanwhile, the stress in the hoisting process is uniform, so that the safety is also 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.
