[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Examples, such as Figures 1 to 4 As shown, the utility model provides an ancient tree trunk hoisting protection device, including a bottom protection frame 1 and a side protection frame 2, the bottom protection frame 1 includes a plurality of arc units 11 and a plurality of U-shaped connecting rods 12, the arc unit 11 includes a top plate 111 and a bottom plate 112, a rib plate 113 vertically connected to the top plate 111 and the bottom plate 112 is arranged between the top plate 111 and the bottom plate 112, the length of the rib plate 113 is greater than the length of the top plate 111 and the bottom plate 112, a plurality of waist-shaped holes 114 distributed along the length direction thereof are arranged on the rib plate 113, the U-shaped connecting rod 12 cooperates with the waist-shaped hole 114 and positioning screws are arranged at both ends thereof Mother 13, the side protection frame 2 includes 8 horizontal units 21 and 8 vertical units 22, the four horizontal units 21 are connected end to end in sequence to form a bottom frame, the bottom frame is used to support the bottom protection frame 1, and the other four horizontal units 21 are connected end to end in sequence to form a top frame, adjacent horizontal units 21 are connected by angle plates 23 and bolts, the vertical unit 22 includes an upper I-shaped plate 221 and a lower I-shaped plate 222, a vertical I-shaped plate 223 is arranged between the upper I-shaped plate 221 and the lower I-shaped plate 222, the upper I-shaped plate 221 is connected to the top frame by bolts, and the lower I-shaped plate 222 is connected to the bottom frame by bolts (not shown in the figure).

[0020] Specifically, the utility model can form a bottom protection frame 1 of different calibers for supporting the bottom of the trunk by using different numbers of arc units 11. The top plate 111 and the bottom plate 112 are respectively supported and matched with the horizontal unit 21 of the trunk and the side protection frame 2. The rib plate 113 is used as a reinforcing structure of the top plate 111 and the bottom plate 112 on the one hand, and provides a certain margin through its arc extension characteristics on the other hand, which is convenient for establishing an assembly relationship with adjacent arc units 11, thereby establishing an adjustable structure, and finally fixed with a U-shaped connecting rod 12, thereby achieving effective protection and support for the bottom of the trunk. Further, the side protection frame 2 provided by the utility model has a back-shaped structure with a bottom frame and a top frame established by the horizontal unit 21, and is supported and connected by a vertical unit 22 in the middle, so that it is used to support the bottom protection frame 1 and protect the side of the trunk through the vertical unit 22. Moreover, the horizontal unit 21 and the vertical unit 22 are both composed of I-beam components, which have a high structural strength, so the protection effect is also relatively high, which is convenient for hoisting and transportation. The bottom protection frame 1 and the side protection frame of the device are assembled in a detachable manner, which is convenient for rapid construction on site, has high adaptability to different application objects, can obtain better protection effect, has reasonable design, no welding, is easy to assemble, is conducive to reducing costs and has high utilization rate.

[0021] In order to improve the bottom protection frame 1 and the assembly performance, the rib plate 113 provided by the utility model is bent and extended from a corner of the top plate 111 toward its diagonal direction, which can provide effective radial margins for adjacent arc units 11, so that the left and right arc units 11 can better form a relatively complete ring structure after the final assembly process; at the same time, after the U-shaped connecting rod 12 is inserted into the waist-shaped hole 114, the two positioning nuts 13 can be distributed on the inner and outer sides of the two rib plates 113 connected thereto with a relatively small spacing distance, which is beneficial to improve the connection reliability between the U-shaped connecting rod 12 and the positioning nuts 13.

[0022] Considering that the trunk and its bottom are generally irregular structures, after the bottom protection frame 1 wraps the bottom of the trunk to a certain extent, the U-shaped connecting rod 12 can provide a certain support for the part with gaps. Therefore, in order to improve the practicality of the U-shaped connecting rod 12, the U-shaped connecting rod 12 provided by the utility model not only has the function of connecting adjacent ribs 113, but also can better adapt to the position of the bottom of the trunk. Specifically, the U-shaped connecting rod 12 includes a U-shaped portion 121, and L-shaped portions 122 are provided at both ends of the U-shaped portion 121. The L-shaped portion 122 is provided with a thread that cooperates with the positioning nut 13. The L-shaped portion is used to connect the ribs 113. If the U-shaped portion extends outward, it only serves to connect the L-shaped portion. If the U-shaped portion is toward the inside of the bottom protection frame 1, it can contact the trunk in the radial position, thereby playing a supporting role, which is beneficial to improve the stability of the trunk during hoisting and transportation.

[0023] In order to improve the assembly performance of the side protection frame 2, the horizontal unit 21 provided by the utility model includes two horizontal I-shaped plates 211. The cross-section of the horizontal I-shaped plate 211 is I-shaped. One end of the horizontal I-shaped plate 211 is provided with an L-shaped opening 212 and is used to cooperate with another horizontal I-shaped plate 211. The other end of the horizontal I-shaped plate 211 is provided with a socket 213, and the socket 213 is used to be plugged into the angle plate 23. The horizontal I-shaped plate 211 and the angle plate 23 are both provided with multiple pairs of bolt holes for cooperating with bolts. Among them, the two horizontal I-shaped plates 211 in the same horizontal unit 21 are butted at their L-shaped openings 212, and horizontal units 21 of different combined lengths are obtained by adjusting the staggered length of the L-shaped openings 212, and the horizontal units 21 in the fore-aft direction can be plugged in through the angle plates 23, thereby realizing the assembly relationship; further, the upper I-shaped plate 221, the lower I-shaped plate 222 and the vertical I-shaped plate 223 of the vertical unit 22 are pre-welded straight before entering the site, and no on-site welding is required. After the vertical unit 22 is in place, it is connected to the horizontal unit 21 and the angle plate 23 by bolts, and finally a protection frame matching the protected object is obtained. In addition to being used for connecting bolts, the bolt holes opened on each unit of the side protection frame 2 can also be connected with lifting tools.

[0024] Furthermore, interfaces 231 cooperating with the socket 213 are provided at both ends of the angle plate 23. The two sides of the angle plate 23 are inserted into the socket 213 through the interfaces, which can limit the free up and down movement of the vertical unit 22 in the fore-and-aft direction, which is beneficial to improve the stability of the base frame, and also provides a stable support horizontal surface for the bottom protection frame.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
