Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic support devices, in particular to a hydraulic outrigger safety support device. Background Art

[0002] In heavy vehicles such as semi-trailers, electric hydraulic outriggers are common auxiliary support equipment. These outriggers are usually installed on the outside of the left and right side beams of the front section of the semi-trailer to assist in supporting the semi-trailer when loading and unloading goods or parking for maintenance, and can adjust the height of the semi-trailer according to the actual height of various tractor seats; traditional hydraulic outriggers generally only play a supporting role, but in actual application, due to the influence of various factors, the hydraulic outriggers may vibrate, but the existing hydraulic outriggers lack corresponding shock-proof mechanisms, which may cause the hydraulic outriggers to become unstable due to vibration during use, which may seriously lead to some safety accidents.

[0003] A Chinese patent discloses a high-stability hydraulic outrigger cylinder (authorization announcement number CN211687955U). The patented technology has a certain shockproof effect, which makes the hydraulic outrigger cylinder less likely to become unstable due to vibration during use, thereby increasing the stability of the hydraulic outrigger cylinder and reducing the occurrence of safety accidents;

[0004] However, it has certain disadvantages: its hydraulic outrigger cylinder contacts the ground through a supporting base, and like most hydraulic outrigger cylinders, the contact area between the hydraulic outrigger cylinder and the ground is small, so the supporting stability needs to be improved.
