Embodiment 1
[0024] Embodiment one of the van truck of the present invention: as Figure 1-5 As shown, it includes a vehicle body 1 and a compartment 10 disposed on the rear side of the vehicle body 1 . The compartment 10 is provided with uprights 101 at its four corners respectively, and the outside of the uprights of the compartment is provided with a compartment skin. The two uprights on the left and right sides are respectively erected with two tracks parallel to each other and extending in the front-to-back direction. form the main girder track. Each monorail of the main beam track includes a fixed track 21 and an overturning track 22, and the overturning track 22 is hinged on the rear end of the fixed track 21 and can rotate along the axis extending left and right. The overturning track 22 is hinged with a telescopic rod 24, and the other end of the telescopic rod 24 is hinged on the fixed track 21, and the telescopic movement of the telescopic rod 24 can realize the rotation of the...

The invention provides a main beam rail and a van type truck with the same. The main beam rail extending in a front-and-back manner is arranged in a compartment of the van type truck and comprises a fixed rail and a turning rail; a supporting plate is hinged to the turning rail, and the main beam rail further comprises a limiting pin which is fixedly arranged relative to the fixed rail; a limiting groove in locking fit with the limiting pin when the turning rail is located at the unfolding position is formed in the supporting plate, and an opening of the limiting groove faces downwards; the main beam rail comprises a safety lock piece, and an ejection portion is arranged on the safety lock piece; the safety lock piece is provided with a locking position, wherein when the top pressing portion moves towards the supporting plate, the supporting plate is locked, and therefore the phenomenon that the supporting plate rotates around the hinge point upwards is avoided; and the safety lock piece is further provided with an unlocking position, wherein when the top pressing portion moves away from the supporting plate, the supporting plate is unlocked. According to the van type truck, the supporting plate is locked through the top pressing portion of the safety lock piece, the phenomenon that the supporting plate vibrates and rotates upwards, and consequently, the supporting plate is separated from the locking pin is avoided, and use is safe and reliable.
Description
technical field [0001] The invention relates to a main beam track and a box truck using the main beam track. Background technique [0002] With the rapid development of the transportation industry, lifting equipment has been widely used. For example, the Chinese utility model patent with the authorized announcement number CN204324751U and the authorized announcement date of 2015.5.13 discloses a crane and a van using the crane. The track includes a fixed track and a reversible track in the compartment. When the reversible track is in the unfolded state, it cantilever horizontally outside the compartment and enables the main girder of the crane on the girder track to move outside the compartment, which is convenient for lifting goods outside the compartment or moving Goods are transported from the inside of the compartment to the outside of the compartment. Wherein the reversible track is hinged with a telescopic rod fixedly connected with the car body and can be unfolded o...
