Transport trolley applied to muddy road of construction site

Abstract

The invention discloses a transport trolley applied to a muddy road of a construction site. A vehicle body is included. Four lifting mechanisms are symmetrically distributed below the vehicle body; each lifting mechanism comprises a wheel supporting block fixedly arranged on a lower end surface of the vehicle body; a wheel frame is arranged below the wheel supporting block; a rotating cavity withan upward opening is arranged in an upper end of the wheel frame; and a rotating sliding block is rotatably arranged in the rotating cavity. In the invention, wheel sinking can be automatically detected when the trolley passes through a muddy road; then the auxiliary lifting mechanism is controlled to be unfolded to increase a contact area between the wheels and the ground; a lifting force is increased through the method of increasing the contact area; in addition, the lifting mechanism can automatically determine an unfolding size according to a sinking degree of the wheels, and action efficiency is improved; and meanwhile, the auxiliary pushing mechanism can apply a forward assisting force to the trolley to help the trolley move on a muddy and wet slide way.

Description

technical field [0001] The invention relates to related fields of building construction, in particular to a transport trolley applied to muddy roads at construction sites. Background technique [0002] In engineering construction, a large amount of material transportation is often required, and due to the complexity of the construction site environment, many large-scale transportation equipment are often inaccessible, so small transport carts are often required in engineering construction, and the construction site requires roads The road conditions are often poor. When it rains, the road will become very muddy, which will cause the wheels of the transport trolley to enter the mud first, which will seriously affect the efficiency of material transportation and engineering construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transport trolley applied to muddy roads at construction sites, which can impro...
