Abstract
Description
Technical Field
[0001] The utility model relates to a climbing ladder for maintaining large trees. Background Art
[0002] When maintaining and pruning branches of large trees, dangers are easily generated, and the maintainers and the people holding the ladders are easily hit and injured by the pruned branches. The existing ladders are inconvenient to carry and have low safety.
[0003] When maintaining large trees in mountain parks or woodlands, climbing mechanical vehicles cannot enter and the existing ladder length is significantly insufficient. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a climbing ladder for tree maintenance.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a climbing ladder for maintaining large trees, including a ladder body, the ladder body is composed of a main surface, a left side and a right side, a left side is provided on the left side of the main surface, and a right side is provided on the right side of the main surface, forming an open frame, and a cavity for people to crawl and stay is formed in the frame; a number of vertically evenly arranged horizontal connecting rods are provided on the main surface, the left side and the right side.
[0006] Furthermore, a connection insertion protrusion is provided at the top of the ladder body; a connection insertion hole is provided at the lower end of the ladder body, and multiple ladder bodies can be inserted and connected to form a whole.
[0007] Furthermore, the connection insertion protrusion and the connection insertion hole are connected by corresponding connection bolts.
[0008] Furthermore, the transverse connecting rods on the main surface, the left side surface and the right side surface are staggered in vertical height from the transverse connecting rods on the main surface.
[0009] Furthermore, the transverse connecting rods on the main surface, the left side surface and the right side surface correspond to the transverse connecting rods on the main surface in vertical height.
[0010] The beneficial effects of the utility model are: the connection is detachable, and the ladder is convenient to carry in the wild and mountainous areas; the chamber for people to crawl and stay is convenient for people to climb and hold the ladder, and people will not be injured by fallen branches after pruning.

[0015] The following is a combination of the appended examples of the present invention Figure 1-4 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0016] Example 1 reference Figure 1-2 The ladder for maintaining large trees includes a ladder body, which is composed of a main surface 1, a left side 2 and a right side 3. The left side is provided on the left side of the main surface, and the right side is provided on the right side of the main surface, forming an open frame, and a chamber 4 for people to crawl and stay is formed in the frame; a number of vertically evenly arranged horizontal connecting rods 5 are provided on the main surface, the left side and the right side.
[0017] For a climbing ladder used for large tree maintenance, the transverse connecting rods on the main surface, the left side and the right side are staggered in vertical height from the transverse connecting rod on the main surface.
[0018] For a climbing ladder used for large tree maintenance, the transverse connecting rods on the main surface, the left side and the right side correspond to the transverse connecting rod on the main surface in vertical height.
[0019] When the pruned branches fall, the presence of the left and right sides and the transverse connecting rods will form a protective layer outside the cavity for people to crawl and stay, thereby protecting relevant personnel.
[0020] Example 2 reference Figure 3 A tree maintenance ladder includes a ladder body, which is composed of a main surface 1, a left side surface 2, and a right side surface 3. The left side surface is provided on the left side of the main surface, and the right side surface is provided on the right side of the main surface, forming an open frame. A chamber for people to crawl and stay is formed in the frame. The main surface, left side surface, and right side surface are provided with a plurality of vertically evenly arranged transverse connecting rods. The left side surface and the right side surface are hinged to the side surface of the main surface, and the left and right sides are provided with a plurality of connecting rods 8 that are movably fixed by cylinders 11. The connecting rods are provided with a plurality of circular holes 10. The transverse connecting rods on the main surface of the adjacent corresponding connecting rods are provided with raised columns 9, which are used to cooperate with the circular holes to fix the connecting rods. The expansion range of the left side surface 2 and the right side surface 3 can be adjusted to further adjust the size of the chamber for people to crawl and stay and improve the stability of the ladder body.
[0021] Example 3 reference Figure 4 , a climbing ladder for tree maintenance, the top of the ladder body is provided with a connecting insertion protrusion 6; the lower end of the ladder body is provided with a connecting insertion hole 7, and multiple ladder bodies can be inserted and connected to form a whole.
[0022] The tree maintenance climbing ladder has a connecting protrusion and a connecting hole connected by corresponding connecting bolts 11. Multiple ladder bodies can be spliced according to actual height requirements; it is convenient to assemble and disassemble.
[0023] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
