Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery installation technology, specifically relating to a pipeline layout structure for a double-ended telescopic boom auxiliary tool. Background Technology

[0002] like Figure 1 As shown, the configuration of the boom with telescopic booms includes an inner boom 1 and an outer boom 3. The inner boom 1 can extend or retract relative to the outer boom 3 (achieved via a telescopic cylinder) to increase the working range. Since the bucket cylinder 2 is mounted on the movable inner boom 1, the piping connected to the boom needs to be connected to the outer boom 3 before it can be connected to the bucket cylinder 2 on the inner boom 1. Because the inner boom 1 and outer boom 3 need to extend and retract, the connecting piping must be a telescopic pipe 4 to allow sliding during extension and retraction.

[0003] The hammer-shear attachment 5 is located on the outer boom 3. When using the scissor attachment, the telescopic boom needs to be extended, requiring a very long attachment. When using the hammer-shear attachment, the extended attachment will dangle on the ground when retracted, affecting both operation and aesthetics. Utility Model Content

[0004] To address the problems of existing technologies, a new pipeline arrangement structure for telescopic boom attachments is proposed. This structure allows the telescopic boom to use the same pipeline length as a normal excavator when attaching shear-type attachments, eliminating the need for pipeline lengthening, thus not affecting operation, and also resulting in an aesthetically pleasing pipeline layout. This utility model provides the following technical solution:

[0005] A double-ended telescopic boom auxiliary pipeline arrangement structure is disclosed. The telescopic boom includes an inner bucket rod and an outer bucket rod, and includes a first pipeline for hammer-shear type auxiliary tools and a second pipeline for bucket cylinders. The first pipeline includes a first input pipe, a first flexible hose, and a first output pipe for connecting the auxiliary tool. The first flexible hose is U-shaped, and the first input pipe and the first flexible hose are connected in an S-shape. The inlet of the first input pipe faces opposite directions to the outlet of the first output pipe. The second pipeline includes a second input pipe, a second flexible hose, and a second output pipe for connecting the bucket cylinder. The second flexible hose is U-shaped, and the second input pipe and the second flexible hose are connected in an S-shape. The inlet of the second input pipe faces opposite directions to the outlet of the second output pipe.

[0006] Preferably, the second pipeline and the first pipeline are stacked vertically, with the second pipeline positioned above the first pipeline.

[0007] Preferably, a first threaded seat for connecting the outer bucket rod is fixedly connected to the first input pipe.

[0008] Preferably, a second threaded seat for connecting the outer plate of the outer bucket rod is fixedly connected to the second input pipe.

[0009] Preferably, a protective plate for preventing the first or second hose from slipping is fixedly connected to the second input pipe, and the protective plate extends upward.

[0010] Preferably, the protective plate is V-shaped or arc-shaped, with its upper end extending outward toward the inner bucket rod.

[0011] Preferably, the end of the first output tube is connected to a quick-release connector.

[0012] Preferably, a fixing plate is fixedly connected to the first output pipe, the fixing plate is provided with fixing holes, and fasteners for threaded connection of the fixing plate are fixedly connected to the inner bucket rod.

[0013] Preferably, both the first and second pipelines are arranged symmetrically about the bucket cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By bending and stacking the first and second pipes between the inner and outer bucket booms, the overall structure is made simpler, avoiding the risk of scratches caused by exposed pipes;

[0016] 2. Both the first and second pipelines are symmetrically arranged about the left and right sides of the bucket cylinder, so that the force is evenly distributed on both sides, reducing the vibration amplitude when the telescopic boom moves. At the same time, the symmetrical structure simplifies the installation and commissioning process, ensures that the force is evenly distributed on both sides of the pipeline, and improves the stability of the equipment operation.

[0017] 3. The arc-shaped protective plate and the inner bucket rod form a double-limiting structure. When the telescopic arm retracts, the hose slides out along the predetermined trajectory. The outer side of the protective plate blocks and the inner side of the inner bucket rod provides double restraint, preventing the first hose and the second hose from slipping off. The extended end of the protective plate also has a flow guiding function. Attached Figure Description

[0026] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0027] like Figure 2-7 As shown, a double-ended telescopic boom auxiliary piping arrangement structure is disclosed. The telescopic boom includes an inner bucket rod 1 and an outer bucket rod 3, connected by a telescopic cylinder 8 to achieve the extension and retraction of the inner bucket rod 1. It includes a first piping 6 for hammer-and-shear type auxiliary tools and a second piping 7 for the bucket cylinder 2. The first piping 6 includes a first input pipe 61, a first flexible hose 62, and a first output pipe 63 for connecting the auxiliary tool. The first flexible hose 62 is U-shaped, and the first input pipe 61 and the first flexible hose 62 are connected in an S-shape. The inlet of the first input pipe 61 faces the same direction as the first output pipe. The outlets of pipe 63 face opposite directions, and the bucket cylinder 2 has a suitable installation gap reserved for the first output pipe 63; the second pipeline 7 includes a second input pipe 71, a second hose 72, and a second output pipe 73 for connecting the bucket cylinder 2. The second hose 72 is U-shaped, and the second input pipe 71 and the second hose 72 are connected in an S-shape. The inlet of the second input pipe 71 faces opposite directions to the outlet of the second output pipe 73. The above can make the pipeline more concentrated and concealed, avoiding the extended pipeline from dangling on the ground when retracted in the retracted state, which would affect the operation when using hammer shears or similar auxiliary tools.

[0028] Specifically, in order to further improve space utilization, the second pipe 7 and the first pipe 6 are stacked vertically, with the second pipe 7 located on the upper side of the first pipe 6.

[0029] Specifically, a first threaded seat 611 is fixedly connected to the first input pipe 61, and the outer bucket rod 3 is connected to the first threaded seat 611 and bolts.

[0030] Specifically, a second threaded seat 711 is fixedly connected to the second input pipe 71, and the outer plate part of the outer bucket rod 3 is connected through the second threaded seat 711.

[0031] Specifically, a protective plate 712 is fixedly connected to the second input pipe 71. The protective plate 712 extends upward and forms an outer barrier against the first hose 62 and the second hose 72, while the inner bucket rod 1 forms an inner barrier. When the telescopic arm cylinder retracts, the first hose 62 and the second hose 72 will gradually slide out of the gap between the inner bucket rod 1 and the outer bucket rod 3. During this process, the protective plate 712 can prevent the first hose 62 and the second hose 72 from slipping off.

[0032] Specifically, the protective plate 712 is arc-shaped, with its upper end extending outwards towards the inner bucket rod 1, facilitating the arrangement of the first hose 62 and the second hose 72.

[0033] Specifically, the first output pipe 63 is arranged at the lower part of the bucket cylinder 2 and the front part of the inner bucket rod 1, and its end is connected to a quick-release connector 64. In another preferred embodiment, a plug can also be connected to facilitate the connection of the drive auxiliary tool. The other end of the first output pipe 63 passes through the lower part of the bottom lug plate of the bucket cylinder 2, which facilitates the connection of the first hose 62.

[0034] Specifically, a fixing plate is fixedly connected to the first output pipe 63. The fixing plate is provided with fixing holes, and the corresponding threaded holes are left at the corresponding positions of the inner bucket rod 1. Fasteners 65 are connected and fixed through the threaded holes. The fasteners 65 press against the fixing plate and are tightened by bolts.

[0035] Specifically, the first pipeline 6 and the second pipeline 7 are arranged symmetrically about the bucket cylinder 2.

[0036] Specifically, the first hose 62 and the second hose 72 are arranged in the gap between the inner bucket rod 1 and the outer bucket rod 3, and the first hose 62 and the second hose 72 are covered with PVC sleeves to prevent them from bumping during movement.

[0037] Specifically, the first input tube 61 and the second input tube 71 are fixed by the positioning component 9 or the tube clamp. The positioning component 9 includes a positioning block and a set bolt. The positioning block is symmetrically provided with a first positioning groove and a second positioning groove. The first input tube 61 and the second input tube 71 are respectively placed in the first positioning groove and the second positioning groove, and the upper side is limited by the set bolt, thereby achieving fixation. The structure is simple and easy to maintain.
