Description

Technical Field

[0001] The utility model relates to the field of telescopic arm structures, and more specifically to a telescopic arm structure for aerial work. Background Art

[0002] The telescopic arm for aerial work is a key component of aerial work equipment. It has a unique structure, working principle, and functional characteristics. It is a mechanical arm structure that can adjust the working range by changing its own length. It is an important support for achieving precise positioning of the aerial work platform at different heights and horizontal distances, providing aerial workers with a flexibly adjustable workspace. It is widely used in many fields such as construction, electricity, street light maintenance, advertising installation, fire rescue, etc.

[0003] When the telescopic arm is in the air during operation, the airflow in the air will cause the telescopic arm to shake, and the workers on the work platform will face the risk of body imbalance, especially in a high-altitude environment. Even a slight shake may cause the workers to lose their center of gravity, which greatly reduces the work efficiency. Therefore, it is necessary to design a telescopic arm structure for high-altitude operation with an auxiliary stabilization mechanism to solve the above problems. Utility Model Content

In this solution, the auxiliary electric telescopic arm under the hanging basket body and the horizontal electric telescopic rod in front of the equipment base can be extended synchronously. The vertical electric telescopic arm in the triangular position can effectively resist the influence of air flow fluctuations in the high altitude on the telescopic arm. Due to the stable triangular support, the vertical electric telescopic arm will not shake violently due to the vibration generated by the movement or operation of heavy objects, thereby providing a stable working environment for the workers working in the hanging basket body at the end of the vertical electric telescopic arm.

[0006] 2. Technical solution

[0009] Furthermore, a self-rebounding rotating shaft is installed between the U-shaped self-rotating pair of plates and the L-shaped connecting piece, and the two U-shaped self-rotating pairs of plates are respectively engaged with the left and right sides of the positioning end piece.

[0010] Furthermore, the inner side wall of the U-shaped rotating pair of plates is fixedly connected with a wear-resistant inner layer, and the wear-resistant inner layer is in contact with the outer side wall of the positioning end piece.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) In this solution, the auxiliary electric telescopic arm under the hanging basket body and the horizontal electric telescopic rod in front of the equipment base can be extended synchronously. After extension, the positioning end piece under the auxiliary electric telescopic arm can be inserted into the concave hollow circular cavity, and the U-shaped self-rotating plate is rotated to both sides of the positioning end piece and the positioning end piece is engaged with the U-shaped self-rotating plate. At this time, the hanging basket body and the horizontal electric telescopic rod and the auxiliary electric telescopic arm are connected to form a triangle. The vertical electric telescopic arm in the triangular position can effectively resist the influence of high-altitude air flow fluctuations on the telescopic arm. Due to the stable triangular support, the vertical electric telescopic arm will not shake violently due to the vibration caused by the movement of heavy objects or operation, thereby providing a stable working environment for the workers in the hanging basket body at the end of the vertical electric telescopic arm.

[0018] (2) During the engagement process between the positioning end piece and the concave hollow circular cavity, the electric push rod can push the synchronous U-shaped push rod outward or backward as a whole, so that the rotation direction of the U-shaped self-rotating plate can be flexibly adjusted. There is no need for manual labor to come to the bottom of the hanging basket body to rotate the U-shaped self-rotating plate to the outside of the positioning end piece, which has a higher safety factor. At the same time, the wear-resistant inner layer provided on the inner side of the U-shaped self-rotating plate can improve the wear resistance coefficient of the connection surface between the positioning end piece and the U-shaped self-rotating plate, thereby extending its service life.
