Problems solved by technology
When multi-directional operations are required, special operation vehicles (such as forklifts) need to turn first, and then move up and down, which is time-consuming and laborious. At the same time, it is inconvenient to perform multi-directional operations in a specific operating environment with limited space, such as forklifts that cannot work normally. Steering, unable to adapt to the requirements of multi-directional operations

Embodiment Construction
[0017] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0018] like figure 1 , figure 2 As shown, the present invention includes a hydraulic cylinder 1 installed at one end of a positioning column 3, a piston 4 is arranged symmetrically inside the hydraulic cylinder 1, a transmission mechanism is also installed inside the hydraulic cylinder 1, and the transmission mechanism includes a tooth mounted between the two pistons 4. Rack 5, the rack 5 is fixedly connected with the piston 4, and the rack 5 meshes with the gear 6 to form a moving pair; such as figure 2 As shown, the inside of the gear 6 is connected with the first rotating shaft 7 through the key, the first rotating shaft 7 is connected with one end of the working gantry 2, and the other end of the working gantry 2 is connected with the other end of the positioning column 3 through the second rotating shaft 8 The movable connection enables the w...

The invention relates to a hydraulic three-directionally-rotating working portal frame. The hydraulic three-directionally-rotating working portal frame comprises a hydraulic oil cylinder and a transmission mechanism, wherein the hydraulic oil cylinder is mounted at one end of a positioning column, the transmission mechanism is positioned inside the hydraulic oil cylinder and is fixedly connected with one end of a working portal frame body through a first rotating shaft, and the other end of the working portal frame body is movably connected with the other end of the positioning column through a second rotating shaft so that the working portal frame body can rotate by 0-180 degrees along with the first rotating shaft and the second rotating shaft. The hydraulic three-directionally-rotating working portal frame is simple in structure, hydraulic oil in the steering oil cylinder is used for driving a piston to move to enable the piston to drive a rack to reciprocate linearly, and since the rack meshes with a gear, and the rack is connected with the working portal frame through the first rotating shaft, the rack drives the working portal frame to rotate, and the hydraulic three-directionally-rotating working portal frame is capable of steering easily without moving in specific operation environments with field limited.
Description
technical field [0001] The invention relates to a steering mechanism, in particular to a hydraulic three-way rotating working gantry used for a forklift gantry, an automated operation line or a working vehicle. Background technique [0002] In the prior art, the working gantry is the main load-bearing structure of the picking device, which is suitable for selecting or placing goods in a warehouse, or for assembling and installing equipment at a certain height. When multi-directional operations are required, special operation vehicles (such as forklifts) need to be steered first, and then moved up and down, which is time-consuming and labor-intensive. At the same time, it is inconvenient to perform multi-directional operations in a specific operating environment with limited sites, for example, the forklift cannot work normally. Steering, unable to adapt to the requirements of multi-directional operations. SUMMARY OF THE INVENTION [0003] Aiming at these shortcomings ...
