Description

Folding track for van-type vehicle-mounted crane

Technical Field

The utility model relates to a folding track is used to van-type crane belongs to on-vehicle crane technical field.

Background

The van-type vehicle-mounted crane is widely applied to logistics transportation of heavy goods of a van truck, is used for completing loading and unloading work of the heavy goods on the van truck, and replaces manual carrying. A van-type vehicle-mounted crane generally comprises a rail and a crane traveling on the rail, and the rail is installed in a carriage of a truck. The track of the traditional van-type crane is mostly of a one-time folding structure, the extending length is limited (depending on the width of a carriage), and the loading and unloading are inconvenient for some cargoes with longer length (such as a assault boat).

Therefore, how to provide an increase track at the epitaxial extension degree's of carriage folding track for van-type crane is the utility model discloses a research purpose.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a folding track for a van crane, which integrally adopts a secondary folding structure, can extend a farther distance from a carriage after being completely unfolded, is convenient for loading and unloading goods with longer length and has wide application range; and can be completely contained in the carriage after the secondary folding, thereby saving space.

For solving the prior art problem, the utility model discloses the technical scheme who adopts is:

the utility model provides a folding track for van-type vehicle crane which characterized in that: the tractor comprises a track support, a track main body arranged at the top end of the track support and a tractor crane arranged on the track main body; the track main body takes one end close to the tractor crane as a starting end and one end far away from the tractor crane as a tail end; the tail end of the track main body is hinged with a first extension track through a rotating shaft; the tail end of the first extension track is hinged with a second extension track through a hinge; the two ends of the tractor crane are arranged on the track main body through walking wheels and limiting wheels.

Furthermore, a support rod is arranged below the first extension track; and a right-angled triangle structure is formed among the support rod, the track support and the first extension track.

Further, the maximum folding angle of the first extension track is 90 °; the maximum folding angle of the second extension track is 180 °.

Further, the travelling wheels travel on the top end face of the track main body; the limiting wheels are positioned on two sides of the track main body.

The beneficial effects of the utility model are that: the whole body adopts a secondary folding structure, can extend out to a farther distance away from the carriage after being completely unfolded, is convenient for loading and unloading goods with longer length, and has wide application range; and can be completely contained in the carriage after being folded for the second time, thereby saving space.

Detailed Description

In order to make the technical solution of the present invention more understandable to those skilled in the art, the present invention is further analyzed with reference to fig. 1 to 5.

As shown in fig. 1-5, a folding track for van crane is characterized in that: the track comprises a track support 1, a track main body 2 arranged at the top end of the track support 1 and a tractor crane 3 arranged on the track main body 2; the track main body 2 takes one end close to the tractor crane 3 as a starting end and takes one end far away from the tractor crane 3 as a tail end; the tail end of the track main body 2 is hinged with a first extension track 5 through a rotating shaft 4; the tail end of the first extension track 5 is hinged with a second extension track 7 through a hinge 6; the two ends of the tractor crane 3 are arranged on the track main body 2 through walking wheels 8 and limiting wheels 9.

In this embodiment, preferably, a support rod 10 is disposed below the first extension rail 5; a right-angled triangle structure is formed among the support rod 10, the rail bracket 1 and the first extension rail 5, and the supporting force of the first extension rail 5 is enhanced by using the stability of the triangle.

In this embodiment, preferably, the maximum folding angle of the first extension track 5 is 90 °, and the first extension track 5 is folded toward the inner side of the track main body 2 during folding; the maximum folding angle of the second extension track 7 is 180 degrees, and the second extension track 7 is folded towards the top end of the first extension track 5 in a turning way during folding.

In this embodiment, preferably, the traveling wheels 8 travel on the top end surface of the rail main body 2; the limiting wheels 8 are positioned on two sides of the track main body 2.

The utility model discloses during the use: install track main part 2 in the carriage through track support 1, when the longer goods of needs loading and unloading length, expand first extension track 5 and second extension track 7 simultaneously and increase the length of track main part 2, fold first extension track 5 and second extension track 7 after the loading and unloading is accomplished, accomodate in the carriage completely, save space.
