Description

Technical Field

[0001] The utility model relates to the technical field of forklift overhead guards, in particular to a forklift cab overhead guard. Background Art

[0002] Forklifts are wheeled vehicles used for loading, unloading, stacking, and short-distance transport of palletized cargo. They are widely used in ports, docks, train stations, and various warehouses. However, the environment places significant restrictions on forklift use. During loading and unloading operations, forklifts often cannot reach designated locations due to the height of overhead guardrails.

[0003] After searching, the patent with announcement number CN220098448U discloses a forklift overhead guard that is easy to install. The structural design of the mounting assembly enhances the overall installation convenience of the device. When in use, the mounting assembly can be used to slide and adjust the overall installation angle of the overhead guard body, so that the overhead guard body can be slid and adjusted to the appropriate position for use, so that it can be positioned and clamped in conjunction with the positioning assembly for installation, thereby enhancing the overall flexibility of the device.

[0004] Although the above solution can achieve the height adjustment of the overhead guard, in actual use, since the various clamping blocks are distributed far apart and are all pushed by springs, it requires the cooperation of multiple people to achieve the height adjustment of the overhead guard so that the overhead guard can pass through the height-restricted area smoothly, which is inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide a forklift cab overhead guard to solve the problems raised in the above background technology.

[0011] As a further solution of the present invention: the bottom of the first cross plate is fixedly connected with a reinforcing rod, the front connecting arm is fixedly connected to the corresponding first cross plate and the reinforcing rod, the two front connecting arms are fixedly connected to each other through a third connecting rod, and the two front branch pipes are fixedly connected to each other through a fourth connecting rod.

[0012] As a further solution of the present invention: the top end of the rear connecting arm is fixedly connected to the corresponding second cross plate, the two rear connecting arms are fixedly connected to each other through the fifth connecting rod, the two rear branch pipes are fixedly connected to each other through the seventh connecting rod, and the bottom of the first cross plate is fixedly connected with a diagonal support rod. When the top end of the core rod is located in the rear connecting arm, the end face of the diagonal support rod is in contact with the outer wall of the rear connecting arm.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] When the utility model is in use, it is only necessary to remove the core rod from the rear connecting arm, and the rear top frame can be turned over relative to the front top frame. Thereafter, the two front connecting arms can be rotated relative to the front branch pipes, which can drive the front top frame to rotate, and the two rear connecting arms can be placed on the top ends of the corresponding rear branch pipes, thereby effectively lowering the height of the overhead guard frame, so that the forklift can pass through the height-restricted area. Thereafter, the above steps can be reversed to restore the overhead guard frame, so as to provide protection for the driver during the use of the forklift. The utility model has good use effect, and the overall structure is simple, and can be operated by one person. BRIEF DESCRIPTION OF THE DRAWINGS
