Description

Technical Field

[0001] The utility model relates to the technical field of forklift door frames, in particular to a rotary door frame used for a forklift. Background Art

[0002] The revolving gantry is one of the key components of modern forklifts. Its main function is to achieve precise handling and stacking of manganese alloy barrels. It consists of columns, beams and a rotating mechanism and is installed in front of the forklift body. The revolving gantry enables the forklift to flexibly adjust the direction of the forks within a limited space, greatly improving the convenience and work efficiency of forklift operation. The design of the revolving gantry fully considers the operator's needs. For example, during the manganese alloy barrel filling process, the operator only needs to gently turn the control handle through a precise transmission system to achieve fast and smooth rotation of the gantry. This innovative function not only reduces the operator's labor intensity, but also improves safety during the operation process. The revolving gantry has become an important equipment for improving transportation efficiency and reducing operating costs.

[0003] According to the search of China Utility Model Publication No.: CN215160743U, a rotating gantry of a forklift is disclosed. 1. When oil is introduced into the rotating cylinder, the two pistons and the rack are pushed to translate relative to the cylinder body. Because the rack is engaged with the gear, and the gear is circumferentially fixed relative to the support shaft, the rack will drive the cylinder body to rotate relative to the gear, thereby causing the gantry connected to the cylinder body to rotate relative to the support shaft. This structure in which the rack cylinder drives the gantry to rotate is cleverly designed and compact. The space required for the gantry rotation is smaller, and the gantry rotation is more flexible. 2. The cylinder body is divided into a cylinder base and two cylinder barrels, which facilitates the disassembly and maintenance of the gear, rack and piston, and makes the assembly of the rotating cylinder more convenient, which is conducive to improving production efficiency. 3. By providing annular lugs and bosses, the positioning and installation between the cylinder barrel and the cylinder base are facilitated, thereby further improving the installation efficiency.

[0004] However, there are some issues that need to be considered when implementing the above technical solution: First, the manganese alloy barrel is prone to tipping over due to force during rotation, and the manganese alloy barrel will deviate from the width of the forklift during rotation, causing the center of gravity to shift out of the width of the forklift; second, the mast can only rotate to one side, which has limitations when used.

The first hydraulic telescopic rod 302 is extended to rotate the first rotating frame 301, rotating the manganese alloy barrel to one side.

[0028] Specifically, the second rotating frame 303 is rotationally connected to the first rotating frame 301. The second rotating frame 303 forms a rotating structure with the first rotating frame 301 through the second hydraulic telescopic rod 304. The second rotating frame 303 matches the first rotating frame 301 in size. The second hydraulic telescopic rod 304 is extended to enable the second rotating frame 303 to rotate the manganese alloy barrel to the other side, thereby improving the flexibility of the gantry.

[0029] Specifically, the third hydraulic telescopic rod 305 forms a rotating structure with the mast body 1 through the first motor 306. Two groups of third hydraulic telescopic rods 305 are arranged. The third hydraulic telescopic rods 305 match the size of the mast body 1. The third hydraulic telescopic rod 305 is extended, and at the same time, the first motor 306 drives the third hydraulic telescopic rod 305 to rotate, extending the universal wheel 308 outward, thereby improving the support of the forklift after the manganese alloy barrel is turned out, and preventing the forklift from tipping over after the center of gravity moves out.

[0030] Specifically, the interior of the third hydraulic telescopic rod 305 is connected to one end of the damping spring 307, and the other end of the damping spring 307 is connected to the universal wheel 308.
