Problems solved by technology

[0003] The structure of the outriggers in the prior art is mainly mechanical. In actual use, the driver needs to get out of the car and shake the outriggers, and manually lift the outriggers by hand. The lifting speed is slow and the efficiency is low, which causes additional troubles for the driver. The workload, and the inconvenience of getting on and off the car may easily cause accidents, and cannot guarantee the safety of drivers and vehicles

Embodiment 1

[0032] Embodiment 1: In order to solve the problem of inconvenient lifting of the outriggers of the semi-trailer, a foldable multi-section pneumatic outrigger is proposed in this embodiment, see Figure 1-4 , including a base plate 1, an engaging mechanism, and a link mechanism. The base plate 1 is a rectangular plate placed horizontally and horizontally. The top surface of the base plate 1 is fixed on the front end of the bottom surface of the semi-trailer. groove, the middle part of the rectangular groove is provided with a linkage bearing plate 11, a linkage bearing is installed in the linkage bearing plate 11, and a threaded long rod 12 penetrating horizontally is inserted in the linkage bearing, and the two sides of the rectangle groove Both ends are equipped with fixed bearings, and the two ends of the threaded long rod 12 are respectively inserted in the corresponding fixed bearings, and the threads on the two sections of the threaded long rod 12 are set in reverse symme...

Embodiment 2

[0036] Example 2: see Figure 5 , in this embodiment, the present invention also proposes a method of using a foldable multi-section pneumatic outrigger, comprising the following steps:

[0037] Step 1, start the uniaxial cylinder 31, control the air rod of the uniaxial cylinder 31 to extend slowly, drive the rack plate 33 to move forward slowly through the limit plate 32, and drive the limit cylinder 35 to slide along the limit rod 34, so that The limit spring is compressed and deformed, and the meshing drives the gear 3 and the long threaded rod 12 to rotate slowly. Since the threads on the two sections of the long threaded rod 12 are arranged in reverse symmetrical helical sleeves, the two threaded cylinders 14 are driven to form a reverse symmetrical horizontal direction. move;

[0038] Step 2, when the two threaded barrels 14 move oppositely and symmetrically, the T-shaped slide rail 13 is driven to slide along the T-shaped chute, and under the coordination of the hinge ...

Abstract

The invention discloses a foldable multi-section type pneumatic supporting leg. The supporting leg comprises a bottom plate, a meshing mechanism and a connecting rod mechanism, a rectangular groove is formed in the bottom face of the bottom plate in a sunken mode, a linkage bearing plate is arranged in the middle of the interior of the rectangular groove, a linkage bearing is installed in the linkage bearing plate, a threaded long rod which transversely penetrates through the linkage bearing is inserted into the linkage bearing, the meshing mechanism is arranged at one end of the threaded long rod, and the connecting rod mechanism is mounted on the threaded long rod. The invention further discloses a using method of the foldable multi-section type pneumatic supporting leg. Through cooperative use of all the mechanisms, the problem that the landing leg of the semitrailer is inconvenient to lift is solved, the overall design is flexible, the height of the supporting leg is convenient to adjust, a driver is prevented from getting off the semitrailer for operation, and the stability of the supporting leg during supporting is improved.

Description

technical field [0001] The invention relates to the field of semi-trailer auxiliary technology, in particular to a foldable multi-section pneumatic support leg and a use method thereof. Background technique [0002] At present, most of the vehicles used to transport bulk cargo in steel mills, docks and other places are semi-trailer dump trucks. In order to improve transportation efficiency and reduce waiting time, units such as steel mills or terminals use terminal tractors to pull semi-trailers. At present, there are movable outriggers in the front section of the semi-trailer, and the movable outriggers should generally be retracted during transportation, so as to reliably avoid the contact between the movable outriggers and the ground and prevent accidents; when the trailer is separated from the tractor, the movable outriggers will fall to assist Support the balance of the car body. [0003] The structure of the outriggers in the prior art is mainly mechanical. In actual...
