Abstract
A middle vehicle frame telescoping mechanism of a commercial vehicle transporting semitrailer is characterized in that a transporting platform comprises front vehicle frames and rear vehicle frames which are arranged on the left side and the right side, each front vehicle frame and the corresponding rear vehicle frame which are located on the same side are connected via a sliding mechanism, the front vehicle frames and the rear vehicle frames are fixed via connecting devices at set positions to form the transporting platform, slide grooves are arranged on the front vehicle frames, and the rear vehicle frames are inserted in the slide grooves to form the sliding mechanisms; and connecting pins of the connecting devices are simultaneously inserted into positioning holes on side surfaces of the slide grooves of the front vehicle frames and positioning holes of the rear vehicle frames, so that the front vehicle frames and the rear vehicle frames are fixed to form the transporting platform. The middle vehicle frame telescoping mechanism has the advantages that the transporting platform can stretch and retract according to actual service conditions, when the transporting platform needs to stretch to be longest, the vehicle frames also stretch to be longest and then are fixed during transporting, and when short articles are conveyed or the transporting platform does not load with anything, the vehicle frames can retract to be shorter or shortest and then are fixed. Besides, when the vehicle frames are shortened, bottom plates of the front and rear vehicle frames match with each other to form a bottom plate structure, the transporting platform can carry more articles, and accordingly the commercial vehicle transporting semitrailer is multipurpose.

Scheme comprises more specifically:
Slide mechanism comprises the chute on the front vehicle frame, and described chute shape matches with the shape of back vehicle frame, and back vehicle frame inserts and constitutes slide mechanism in the chute; Described connecting device comprises knock hole, back vehicle frame knock hole and the connecting pin of front vehicle frame chute side, and the knock hole, the back vehicle frame knock hole that insert front vehicle frame chute side at the desired location connecting pin simultaneously are fixed as shipping platform with front vehicle frame and back vehicle frame; Described chute is a U type chute, and the knock hole of described front vehicle frame chute side is two sides that are positioned at chute, and described connecting pin is that the knock hole, the back vehicle frame knock hole that insert front vehicle frame chute both sides simultaneously are fixed as shipping platform with front vehicle frame and back vehicle frame.
The knock hole in its outside of the knock hole of described front vehicle frame chute both sides is a taper hole, and the pin head of described connecting pin is the taper pin that matches; Described connecting pin is the telescopic connecting pin of horizontally disposed level; Described connecting pin be be arranged on front vehicle frame on oil cylinder be connected, drive by oil cylinder and stretch.
Front vehicle frame inboard, the described left and right sides has the front vehicle frame base plate respectively; There is back frame panel at the vehicle frame middle part behind the left and right sides; The width of back frame panel matches with the room between the front vehicle frame base plate of the left and right sides; When being in the vehicle frame punctured position, back frame panel inserts and constitutes the shipping platform base plate in the room between the front vehicle frame base plate of the left and right sides.
Advantage of the present invention is that shipping platform can stretch according to actual condition of service, when need adopt extreme length to transport, can vehicle frame be fixed on the extreme length position and transport; When short part article of transportation or zero load; Can vehicle frame be fixed on short or the shortest position, and when vehicle frame shortened, forward and backward frame panel complemented each other to form base arrangement; Can load more kinds of article, realize that a car uses more.
