Embodiment Construction
[0019] In the prior art, in a semi-trailer with an outrigger connecting device, the outrigger connecting device is usually arranged near the front end of the semi-trailer. Such as figure 1 As shown, wherein, the outrigger connection device 10 generally includes left and right outrigger assemblies 20, outrigger inclined beams 11 and outrigger middle beams 12 connected between the left and right outrigger assemblies 20, and the drive for driving the outrigger assemblies to work Gear transmission mechanism 13 etc. Wherein, each outrigger assembly includes a outrigger 21 and a outrigger connecting plate 22, and the outrigger connecting plate 22 bears the support reaction force transmitted from the ground to the outrigger 21, and transmits the support reaction force to the vehicle frame, thereby Provide stable support to the frame. Such as figure 2 As shown, the shape of the leg connection plate 22 of the leg connection device in the prior art is generally asymmetrical.

The invention relates to a semi-trailer with a connecting device of landing legs and comprises a connecting device of landing legs that is fixed on a trailer frame, and the connecting device of landing legs comprises a left landing leg component, a right landing leg component and a gear transmission mechanism, wherein, the landing leg component comprises a landing leg, a connection board of landing legs, a support board and a connection angle iron, an adjustment mechanism that is used for leading the connection angle iron to move in the front and back direction relatively to the connection board of landing legs is arranged between the connection angle iron and the connection board of landing legs. Due to the connection angle iron that is arranged in the left and right landing leg components and connected between the bottom of the trailer frame and the connection board of landing legs and the adjustment mechanism that is arranged between the connection angle iron and the connection board of landing legs, the invention leads the connection angle iron to move in the front and back direction relatively to the connection board of landing legs, thus leading the landing leg components to be adjusted in the front and back direction relatively to the trailer frame; the invention can satisfy different loading situations by adjusting the gravity center position of the trailer, thus leading a semi-trailer parking to be more stable and safer, and as the connecting device of landing legs is self-adjusted, the invention is suitable for the semi-trailers in different models and simplifies the processing and the assembly of the semi-trailers.
Description
technical field [0001] The invention relates to a semi-trailer, in particular to a semi-trailer with a leg connecting device. Background technique [0002] The outrigger connection device is a special device on the semi-trailer, which mainly provides stable support for the entire frame when the semi-trailer is parked to ensure its safety. Such as figure 1 As shown, this outrigger connection device 10 generally includes left and right outrigger assemblies 20, outrigger inclined beams 11 and outrigger middle beams 12 connected between the left and right outrigger assemblies 20, and gear transmission for driving the outrigger assemblies to work. Institution 13 et al. Wherein, each outrigger assembly includes a outrigger 21 and a outrigger connecting plate 22, and the outrigger connecting plate 22 bears the support reaction force transmitted from the ground to the outrigger 21, and transmits the support reaction force to the vehicle frame, thereby Provide stable support to th...
