Trackless self-jacking sliding plate dolly

Abstract

The invention relates to a dolly for transporting large objects, in particular to a dolly for moving large precast products or steel members. The dolly adopts the technical scheme that a trackless self-jacking sliding plate dolly is characterized in that supporting legs are respectively arranged at two ends of a bracket; a moving box is movably arranged on a beam; the lower side of the moving box, namely one sides of the supporting legs, extends out the bracket; the height of the extending part is greater than that of a jacking cylinder which retracts each supporting leg and is positioned on the lower side of the bracket and smaller than that of the jacking cylinder which extends out each supporting leg and is positioned on the lower side of the bracket; a moving supporting piece is arranged on the upper side of the moving box; the moving box is connected with the bracket through the jacking cylinders; and the jacking cylinders achieve the sliding movement of the moving box on the beam. By adopting the scheme, the dolly overcomes the deficiencies of the prior art, and has the advantages that the structure is reasonable, the bearing capacity is large, and tracks are not required tobe laid.

Description

Technical field [0001] The invention relates to a trolley for transporting large objects, in particular to a vehicle for moving large prefabricated parts or steel components. Background technique [0002] At present, many types of delivery vehicles appear on the market. Due to their structural characteristics, existing vehicles need to be equipped with tracks when carrying heavy objects, and then the vehicles run on the set tracks. There are some shortcomings during operation: 1. Because the track needs to be laid, the requirements on the roadbed are relatively high; 2. When the roadbed is uneven, the track is difficult to lay, which limits the scope of use; 3. The body is articulated with the front of the car, and the individual bicycle units on the body are articulated, so that once the wheels of the outgoing car are bent while carrying objects, it is difficult for the running car to continue running, and the wheels are easily damaged. Summary of the invention [0003] The purp...

[0002] At present, there are many types of transport vehicles on the market. Due to their structural characteristics, when the existing vehicles carry heavy objects, they need to be equipped with tracks, and then the vehicles run on the set tracks. The above-mentioned types of vehicles There are some defects during operation: 1. Due to the laying of the track, the requirements for the roadbed are relatively high; 2. When the roadbed is uneven, the track is difficult to lay, which limits the scope of use; 3. The rail car The body and the front of the vehicle are hinged, and each single unit on the body is hinged, so that once the wheels of the transport vehicle are bent when carrying objects, it is difficult for the running vehicle to continue to run, and the wheels are easily damaged
