Abstract

The invention relates to the field of rail operation equipment, especially to a rail-engaging mechanism and a truck-mounted crane and a truck with the application of the mechanism. The rail-engaging mechanism comprises a rack. A floating shaft which at least can float up and down is rotatably arranged on the rack. The floating shaft is equipped with friction driving wheels, which rotate to drive the rack to move. The rack is also provided with carrying rollers and elastic devices used for providing the floating shaft with elastic force towards the operational track so as to compress the friction driving wheels on the operational track. The elastic device contains a floating shaft seat which is in running fit with the floating shaft and an elastic part which is arranged between the floating shaft seat and the rack and provides the floating shaft with elastic force towards the operational track. According to the invention, the problem that friction driving wheels are easy to upwarp or gnaw track due to unbalanced force on an existing rail-engaging mechanism is solved.

Description

technical field [0001] The invention relates to the field of rail running equipment, in particular to a rail traveling mechanism and a truck-mounted crane and a truck using the mechanism. Background technique [0002] At present, the loading and unloading of goods is mostly completed by manpower and forklifts. For heavier goods, loading and unloading is particularly difficult and the loading and unloading efficiency is low. In order to reduce labor intensity and improve the loading and unloading efficiency of goods, the Chinese patent with the announcement number CN203624883U and 2014.06.04 Disclosed is a box-type truck-mounted crane, which includes a carriage, a fixed rail device installed in the carriage, a moving rail device, a moving trolley, a lifting mechanism and a traction system, wherein the moving trolley and the moving rail device are both rail walking devices. First drive the mobile rail device to move until it hangs out of the compartment, and then drive the mob...
