Technical Field
[0001] The utility model relates to the technical field of aerial work engineering, and particularly relates to a variable amplitude slewing work platform. Background Technique
[0002] Aerial work generally refers to working at heights, which means working at a height based on a certain position. When working at heights, a crane is generally used to lift the work platform to the corresponding height through the boom, so as to facilitate the operator to carry out aerial work and the transportation of materials at high altitudes. After retrieval, the patent with the publication number CN118270703A discloses a control method, a processor and an aerial work platform for an aerial work platform. Its slewing adjustment position is arranged below the boom. If it is necessary to perform a slewing operation on the work platform arranged at the top of the boom, a relatively large adjustment is still required. During the adjustment, the whole boom moves. In the case of a limited working place range, such a large slewing operation cannot be carried out. Therefore, a variable amplitude slewing work platform that can perform self-slewing and variable amplitude adjustment from above the boom of the lifting equipment is designed to be applicable to limited working places and be flexibly applied to complex working conditions.

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments.

[0022] Embodiment:
[0023] Please refer to Figures 1-3 , a variable - amplitude slewing working platform, which includes a fixed seat 1 installed at the top of the boom of a lifting device and a working platform 4 arranged above the fixed seat 1. A turntable 3 is arranged between the fixed seat 1 and the working platform 4. The turntable 3 is connected to the working platform 4 through a luffing adjustment mechanism, and the turntable 3 is connected to the fixed seat 1 through a slewing adjustment mechanism. The luffing adjustment mechanism can drive the working platform 4 to perform horizontal amplitude adjustment, and the slewing adjustment mechanism can drive the working platform 4 and the luffing adjustment mechanism as a whole to perform slewing adjustment.
[0024] Specifically, the slewing adjustment mechanism includes a slewing support seat 2 fixedly installed on the fixed seat 1. An inner rotating platform with its top fixedly connected to the bottom of the turntable 3 is rotatably connected to the slewing support seat 2. A slewing driving member for driving the inner rotating platform to rotate within the slewing support seat 2 is arranged on the slewing support seat 2. Through the slewing driving member, it is convenient to drive the inner rotating platform to perform circumferential rotation within the slewing support seat 2, thereby driving the turntable 3 and the working platform 4 arranged above the turntable 3 to perform slewing adjustment, so that the working platform 4 can rotate horizontally by 360°.
[0025] Specifically, the slewing drive member includes a slewing gear ring 11 fixedly installed on the inner rotating platform. A slewing adjusting gear 12 meshing with the slewing gear ring 11 is rotatably connected to the slewing support base 2. A slewing adjusting drive motor 13 for driving the slewing adjusting gear 12 to rotate is also fixedly installed on the slewing support base 2. Further, the slewing adjusting drive motor 13 is set as a forward and reverse motor. Starting the slewing adjusting drive motor 13 to make the output shaft of the slewing adjusting drive motor 13 rotate clockwise or counterclockwise facilitates driving the slewing adjusting gear 12 to rotate clockwise or counterclockwise, thereby driving the inner rotating platform to rotate counterclockwise or clockwise.
[0026] Specifically, the luffing adjusting mechanism includes two sets of lifting components symmetrically arranged on both sides of the turntable 3. The lifting component includes a luffing adjusting drive cylinder 6. The bottom of the luffing adjusting drive cylinder 6 is hinged to the side wall of the turntable 3 through a side lower hinge shaft 7, and the output end of the luffing adjusting drive cylinder 6 is hinged to the bottom of the working platform 4 through a side top hinge shaft 8. Through the two sets of lifting components, it is convenient to lift the whole working platform 4. At the same time, by adjusting the length of the lifting components on each side, the inclination angle of the working platform 4 can be correspondingly adjusted. Further, the turntable 3 can be set as pneumatically driven or hydraulically driven, and preferably hydraulically driven.
[0027] Specifically, a center positioning component is arranged between the two sets of lifting components. The center positioning component includes a support block fixedly installed on the top of the turntable 3 and a rotating block fixedly installed on the bottom of the working platform 4. The support block and the rotating block are rotatably connected through a center hinge shaft 5. By setting the center positioning component, the height of the working platform 4 is controlled, thereby restricting the lifting of the working platform 4 by the two lifting components, ensuring the stability of the luffing adjustment, facilitating the working platform 4 to perform a luffing adjustment of ±7° horizontally, and being able to adapt to most working scenarios with the cooperation of the slewing adjusting mechanism.
[0028] Specifically, extension platforms 9 are detachably connected to both sides of the working platform 4. By adding the extension platforms 9, it is convenient to extend the operation length and distance. When the space does not allow, the extension platforms 9 can be disassembled to improve flexibility, and at the same time, they can be conveniently disassembled when put away for easy storage.
[0029] Specifically, guardrails 10 are installed on both the working platform 4 and the extension platforms 9. By setting the guardrails 10, it is convenient to protect the operators standing on the working platform 4 and the extension platforms 9 and prevent the materials placed on the working platform 4 and the extension platforms 9 from falling.
