The utility model provides a technical scheme that its technical problem adopted is:
carry heavy type and drag row car connecting device, including rectangular frame, connecting plate and reinforcing plate, both ends all are fixed with around the rectangular frame the connecting plate, the connecting plate deviates from rectangular frame's a terminal surface and includes boss face and through-hole face, the boss faces upward protruding formation boss, be provided with the connect the through-hole that a plurality of runs through the connecting plate on the through-hole face, still be provided with a plurality of between connecting plate and the rectangular frame the reinforcing plate, and the one end and the rectangular frame of reinforcing plate are connected, and the other end and the connecting plate of reinforcing plate are connected.
Furthermore, the lifting device further comprises lifting lugs, and a plurality of lifting lugs are arranged on the side wall of the rectangular frame.
Furthermore, the rectangular frame comprises four steel plates, and the four steel plates are welded end to form the rectangular frame.
Further, the height of boss face boss is 5 mm.
Furthermore, the surface of the boss surface boss is flat and smooth.
Furthermore, the through hole surfaces are positioned at the left end and the right end of the connecting plate, and the left end and the right end of the connecting plate extend out of the port of the rectangular frame.
The utility model has the advantages that: the boss is arranged on the connecting plate, so that the friction force at the rigid connection part is increased, and the shearing force of the rigid bolt on the connecting through hole is reduced; reinforcing the welding position by adopting reinforcing plates at two sides of the connecting plate to reinforce the strength of the welding seam connection position; through using the utility model discloses connect the heavy pallet truck of year, solved the rigid connection problem of the heavy pallet truck of year, thereby guaranteed the security that the heavy pallet truck of year connects, realized maneuverability and enforceability etc. that many pallet trucks are connected.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a heavy-duty trailer connecting device, including rectangular frame 1, connecting plate 2 and reinforcing plate 3, both ends all are fixed with around rectangular frame 1 connecting plate 2, the one end that connecting plate 2 deviates from rectangular frame 1 include boss face 201 and through-hole face 202, boss face 201 makes progress the arch and forms the boss, be provided with a plurality of through-hole connection hole 4 that runs through connecting plate 2 on the through-hole face 202, still be provided with a plurality of between connecting plate 2 and the rectangular frame 1 reinforcing plate 3, and reinforcing plate 3's one end and rectangular frame 1 are connected, and reinforcing plate 3's the other end and connecting plate 2 are connected. The connecting plates 2 at the front end and the rear end of the rectangular frame 1 are connected with one pallet truck, the rear connecting plate 2 is connected with the other pallet truck, the lug bosses are arranged on the connecting plates 2, so that when the connecting plates 2 are connected, the contact surfaces of the connecting parts are completely jointed, namely the lug boss surfaces are completely jointed, the friction force of the rigid connecting part is increased by arranging the lug bosses, and the shearing force of the rigid bolt at the connecting through hole 4 is reduced; in the embodiment, the connecting plate 2 is fixed on the rectangular frame 1 by welding, and the reinforcing effect of the welding position is performed on the two sides of the connecting plate 2 by adopting the reinforcing plates 3, so that the strength of the welding seam connecting position is reinforced; through using the utility model discloses connect the heavy pallet truck of year, solved the rigid connection problem of the heavy pallet truck of year, thereby guaranteed the security that the heavy pallet truck of year connects, realized maneuverability and enforceability etc. that many pallet trucks are connected.
