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 track and a van using the main beam track. The main beam track extending forward and backward is arranged in the compartment of the van truck. The main beam track includes a fixed track and an overturning track, and the overturning track is hinged There is a support plate, and the main beam track also includes a limit pin that is fixedly arranged relative to the fixed track. The support plate is provided with a limit groove that locks and cooperates with the limit pin when the flip track is at the unfolded position. The groove of the limit groove The mouth of the main beam is facing downward, and the main beam track includes a safety lock. The safety lock is provided with a pressing part. The locking position of the upper rotation, the safety lock also has an unlocking position for releasing the locking of the support plate when the pressing part moves away from the support plate. The van truck of the present invention can lock the support plate through the pressing part of the safety lock, avoiding the upward rotation of the support plate due to vibration and detaching from the locking pin, and is safe and reliable during use.
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...
