Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example 1

As shown in fig. 1 to 4, the felling robot arm according to embodiment 1 includes a protective outer tube 1 and a threading inner tube 2, which are identical in length direction, the threading inner tube 2 is detachably disposed inside the protective outer tube 1, a reinforcing partition rib 3 extending axially along the threading inner tube 2 is disposed inside the threading inner tube 2, and the reinforcing partition rib 3 and the threading inner tube 2 enclose three threading channels 4 distributed at intervals; the threading inner tube 2 is matched with the protection outer tube 1 in an inserted manner, and a locking assembly for locking the threading inner tube 2 to the inner side of the protection outer tube 1 is arranged between the threading inner tube 2 and the protection outer tube 1; a guide groove 5 and a guide convex strip 6 which are in sliding fit are arranged between the threading inner tube 2 and the protection outer tube 1, the guide groove 5 and the guide convex strip 6 both extend along the length direction parallel to the threading inner tube 2, the guide groove 5 is fixed on the outer surface of the threading inner tube 2, and the guide convex strip 6 is fixed on the inner surface of the protection outer tube; the locking assembly comprises a first locking hole 1-1 arranged on the protective outer tube 1 and a second locking hole 2-1 arranged on the threading inner tube 2, and the first locking hole 1-1 and the second locking hole 2-1 are in inserted fit through a locking bolt 7; the first lock hole 1-1 is a blind hole arranged on the circumferential inner wall of the protective outer tube 1, and the second lock hole 2-1 is a through hole.

The mechanical arm of the embodiment is installed in front of the felling machine, and firstly, installation and laying of the power cable and the hydraulic oil pipe of the hydraulic oil cylinder are carried out. The inner threading pipe 2 is taken out from the outer protective pipe 1, and then the electric power cable and the hydraulic oil pipe which are needed to be used are passed through the threading channel 4 of the inner threading pipe 2. The threading inner tube 2 adopts a hollow tubular structure, so that the whole weight of the mechanical arm can be reduced, the energy consumption required for driving the mechanical arm to move is reduced, and the energy conservation is realized. And in the inside of threading inner tube 2, utilize to strengthen separating muscle 3 not only can play the intensity of strengthening the structure of threading inner tube 2, can also use with the cooperation of threading inner tube 2, form a plurality of divided threading passageways 4 in order to enclose to close, when the route is laid, can pass through different threading passageways 4 with different pipelines (including hydraulic pressure oil pipe and electric power cable), the influence of interfering mutually has been avoided, after one of them pipeline breaks down, can take out this pipeline from its threading passageway 4 that corresponds, and avoid causing the influence to other pipelines.

After electric power cable and hydraulic pressure oil pipe passed through threading passageway 4, will protect outer tube 1 cover on threading inner tube 2, through the sliding fit between guide groove 5 and the direction sand grip 6, be favorable to guaranteeing stable relative slip between protection outer tube 1 and the threading inner tube 2. When the two parts slide relatively to each other until a first lock hole 1-1 on the protection outer tube 1 is aligned with a second lock hole 2-1 on the threading inner tube 2, the locking bolt 7 passes through the second lock hole 2-1 from the inner side of the threading inner tube 2 and then is inserted into the first lock hole 1-1, so that the locking connection between the protection outer tube 1 and the threading inner tube 2 is realized, and the two parts are prevented from sliding relatively again. Because the locking bolt 7 passes through the pipe wall of the threading inner pipe 2 from the inside of the threading inner pipe 2 and is inserted into the first lock hole 1-1, the outer surface of the protective outer pipe 1 is prevented from being perforated, and water vapor is easy to enter the protective outer pipe 1 and the threading inner pipe 2 through the perforated part. Therefore, the integrity of the outer surface of the outer protection tube 1 is ensured, and the protection of the outer protection tube 1 on the inner threading inner tube 2 and various pipelines inside the inner threading tube 2 is enhanced.

It should be noted that the structural form of the reinforcing and separating rib 3 is not limited to the structural form corresponding to the drawing of the embodiment, the number of the threading passages 4 formed by the reinforcing and separating rib 3 and the threading inner tube 2 is not limited to three, and according to different use requirements, the reinforcing and separating rib 3 may be in other structural forms to divide the internal space of the threading inner tube 2 into other threading passages 4 in a plurality of numbers.

Example 2

As shown in fig. 5 to 8, the felling robot arm according to embodiment 2 is different from embodiment 1 in that the threading inner tube 2 includes a threading through groove 2a and a sealing cover plate 2b which are identical in length direction and detachably connected, the sealing cover plate 2b is covered on a notch of the threading through groove 2a, and the three threading passages 4 are connected with the sealing cover plate 2 b; the wire-installing through groove 2a is matched with the sealing cover plate 2b in a clamping manner; the groove both sides wall that the logical groove 2a of wiring is led to is provided with chimb 10, is provided with location mouth 9 and joint interface 11 on chimb 10, and sealed apron 2b leads to the adjacent one side of groove 2a with the wiring and is provided with protruding 8 in location and joint piece 12, and the protruding 8 in location cooperates with location mouth 9 grafting, joint interface 11 and the cooperation of joint piece 12 joint.

In this embodiment, threading inner tube 2 mainly comprises logical groove 2a of threading and sealed apron 2b two parts, adopts this mode, when laying the pipeline, can directly take off sealed apron 2b, makes the notch that the logical groove 2a of threading expose, then will need the oil pipe of laying or the electric power cable directly place with the logical groove 2a of threading in, compare in embodiment 1 with longer oil pipe or electric power cable pass through threading passageway 4, the oil pipe and the cable installation of this embodiment are more convenient. After placing the completion, aim at the location mouth 9 on the chimb 10 with the protruding 8 of location on the sealed apron 2b, then go into joint piece 11 card in the joint mouth 11, realize the joint cooperation between sealed apron 2b and the logical groove 2a of threading, accomplish the work of assembling of threading inner tube 2. At this moment, the insertion fit between the positioning opening 9 and the positioning protrusion 8 can prevent the sealing cover plate 2b and the threading through groove 2a from sliding relatively, and the stability of the whole structure of the threading inner pipe 2 is ensured.

When pipeline trouble need be maintained, can press joint piece 12 and make it break away from behind the joint mouth 11, will seal apron 2b and take off from the logical groove 2a of wiring, thereby make the notch that the logical groove 2a of wiring expose, so that get the oil pipe or the electric power cable that break down and change, then will seal apron 2b lid and locate the notch department that the logical groove 2a of wiring, accomplish the equipment work of threading inner tube 2 through the joint cooperation, convenient operation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
