Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a simple anti-rotation aerial work platform. Background Art

[0002] An aerial work platform is a product for mobile aerial work, equipment installation, maintenance, etc. in various industries. A work bar is usually installed at the end of the boom of a boom-type aerial work platform or an aerial work vehicle, and an operator is located in the work bar to perform corresponding aerial work. The work bar is usually connected to the boom support through a swing oil cylinder and can rotate within a range of 90° to the left and 90° to the right. In order to facilitate accurate positioning of the operator on the work platform during construction, the existing aerial work platform is usually equipped with a swing oil cylinder that can rotate the work platform. The swing oil cylinder can rotate according to the actual application needs of the operator and stop at a specified position. After stopping, since the swing oil cylinder is provided with a balance valve for self-locking, it can prevent the work platform from generating abnormal rotation faults.

[0003] When the work platform of the aerial work is working, it is necessary to always keep the work platform in a stable state to facilitate the operation and construction of engineering technicians. The existing aerial work platform is not provided with a platform anti-rotation device. When a certain position of the work platform is strongly impacted or the operator on the work platform is constructing under harsh working conditions, such as when performing surface sandblasting construction, due to the large pressure of the spray gun, the large reaction force generated drives the work platform to rotate abnormally, thereby damaging the above-mentioned swing oil cylinder and affecting the construction safety of the operator on the work platform. Summary of the Utility Model

[0004] In order to overcome the defect that the swing oil cylinder of the aerial work platform is damaged when it is strongly impacted or the operator is constructing under harsh working conditions in the prior art, the utility model provides a simple anti-rotation aerial work platform.

The work platform is installed on a cantilever through a swing oil cylinder. The support plates are symmetrically arranged on both sides of the swing oil cylinder. The work platform is symmetrically provided with a first pin shaft and a second pin shaft. The cantilever is provided with a third pin shaft. The lower part of the support plate is provided with a lower through hole that cooperates with the first pin shaft. The upper part of the support plate is provided with an upper through hole that cooperates with the third pin shaft.

[0018] Refer to Figures 1 to 3, an embodiment of the present utility model discloses a simple anti-rotation aerial work platform, which includes a work platform 1 and two support plates 4. The work platform 1 is installed on a cantilever frame 3 through a swing oil cylinder 2. The support plates 4 are symmetrically arranged on both sides of the swing oil cylinder 2. First pins 5 and second pins 6 are symmetrically arranged on the work platform 1. A third pin 7 is arranged on the cantilever frame 3. A lower through hole 8 that cooperates with the first pin 5 is arranged at the lower part of the support plate 4. An upper through hole 9 that cooperates with the third pin 7 is arranged at the upper part of the support plate 4. A middle through hole 10 that cooperates with the second pin 6 is arranged in the middle of the support plate 4. Plug pins 12 for limiting the support plate are arranged at both ends of the first pin 5, the second pin 6, and the third pin 7.
