Loading dumper

Abstract

The invention discloses a loading dumper. The loading dumper comprises a vehicle frame and further comprises a hook, a coil and a gear set. The gear set is arranged on the vehicle frame. The hook is connected with the gear set through the coil. The gear set comprises an upper gear, a lower gear and a check tappet. One end of the coil is wound on the upper gear, and the lower gear is engaged or disengaged with the upper gear. The check tappet is provided with a telescopic connecting rod matched with tooth spaces of the upper gear. One end of the connecting rod is provided with a stopping face and a sliding face. When teeth of the upper gear make contact with the stopping face, the connecting rod is inserted in one tooth space of the upper gear to stop the upper gear from rotating, and when the teeth of the upper gear make contact with the sliding face, the connecting rod stretches and retracts back and forth to slide on tooth surfaces of the upper gear so as to make the upper gear rotate. By arranging the stopping face and the sliding face at one end of the connecting rod, the different effects of the check tappet on the upper gear, namely stopping the upper gear from rotating or enabling the connecting rod to slide on the tooth surfaces of the upper gear of, are achieved.

Description

technical field [0001] The invention relates to the technical field of transport vehicles, in particular to a loading and unloading vehicle. Background technique [0002] As a means of transportation, cargo handling vehicles are widely used in various industries. During the construction of large-scale steel structures, due to the relatively large volume of structural parts, they are usually transported by means of cranes or forklifts. However, in actual engineering projects, the handling workload of small equipment and structures is increasing. For cranes or forklifts, their mobility is good, but they need a certain working space, which is limited by the space around the structures. , therefore, it cannot function normally in low, narrow or deep spaces, and its use cost is relatively high. At present, the transportation of small equipment is mainly through forklifts or cranes. In the case of limited working space, there is generally no fixed method, and it is mainly comple...

However, in actual engineering projects, the handling workload of small equipment and structures is increasing. For cranes or forklifts, their mobility is good, but they need a certain working space, which is limited by the space around the structures. , therefore, it cannot function normally in low, narrow or deep interior spaces, and its use costs are high

At present, the transportation of small equipment is mainly through forklifts or cranes. In the case of limited work space, there is generally no fixed method, and it is mainly completed by guide chains or manpower. The work efficiency is very low, and it is easy to transport small equipment. or structural damage
