Description

Technical Field

[0001] This utility model relates to a hose protection device, belonging to the field of aerial work platforms. Background Technology

[0002] When working, aerial work platforms need to control the rotation of the turntable and the rise and fall of the boom to adjust the position of the work bucket. Currently, most structures have exposed hoses or wiring harnesses at the connection between the boom and the turntable, or they are covered with rainproof cloth. These are easily scratched or aged by tree branches, which also affects the overall appearance of the product. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a hose protection device with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The hose protection device includes a turntable, a working arm, and a pin. The working arm is mounted on the turntable via the pin. Its structural feature is that it also includes a cable chain and a support frame. The support frame is mounted on the pin. One end of the cable chain is connected to the turntable, and the other end of the cable chain is connected to the working arm. The cable chain is mounted on the support frame. The support frame includes a support sleeve and a limiting frame. One end of the support sleeve is mounted on the pin, and the limiting frame is located at the other end of the support sleeve.

[0005] Furthermore, both ends of the cable chain are equipped with cover plates.

[0006] Furthermore, the cable chain is mounted on the support sleeve, and the cable chain is in contact with the limiting frame.

[0007] Furthermore, one end of the support sleeve is provided with an end plate and an ear plate. The end plate is mounted on the pin shaft by screws, and the ear plate is mounted on the turntable by screws.

[0008] Compared with the prior art, the present invention has the following advantages: the cable chain of the hose protection device is installed at the hinge of the working arm and the turntable, and the hose, wire harness, etc. are placed in the cable chain. The cable chain can move with the working arm and the turntable to reduce the scratching and aging of the hose or wire harness, and play a role in protecting the hose or wire harness.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0016] Example.

[0017] See Figures 1 to 5 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0018] The hose protection device in this embodiment includes a turntable 1, a working arm 2, a pin 3, a cable chain 4, and a support frame 5. The working arm 2 is mounted on the turntable 1 via the pin 3, and the support frame 5 is mounted on the pin 3. One end of the cable chain 4 is connected to the turntable 1, and the other end of the cable chain 4 is connected to the working arm 2. The cable chain 4 is mounted on the support frame 5, and both ends of the cable chain 4 are equipped with cover plates 7.

[0019] In this embodiment, the support frame 5 includes a support sleeve 8 and a limiting frame 11. One end of the support sleeve 8 is mounted on the pin 3, and the limiting frame 11 is located at the other end of the support sleeve 8. The drag chain 4 is mounted on the support sleeve 8 and is in contact with the limiting frame 11. That is, one end of the support sleeve 8 is provided with an end plate 9 and an ear plate 10. The end plate 9 is mounted on the pin 3 by screws, and the ear plate 10 is mounted on the turntable 1 by screws.

[0020] Specifically, one end of the cable chain 4 is bolted to the turntable 1, and the other end of the cable chain 4 is bolted to the working arm 2. The turntable 1 and the working arm 2 are hinged together by the pin 3. The end plate 9 is mounted on the pin 3, the ear plate 10 is mounted on the turntable 1, the support sleeve 8 supports the cable chain 4, and the limit bracket 11 blocks the cable chain 4 for limiting. The cable chain 4 is designed so that the upper and lower cover plates 7 can be opened, which facilitates the installation of the hose 6 or wire harness inside the cable chain 4. After the hose 6 is installed, the cover plate 7 is installed to provide protection. When the working arm 2 rotates around the pin 3, the cable chain 4 moves around the support sleeve 8, and the hose 6 or wire harness moves simultaneously inside the cable chain 4.

[0021] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model are included within the protection scope of this utility model.
