Description

Tunnel mode control system of forklift and narrow-roadway forklift Technical Field The invention relates to the technical field of forklifts, in particular to a tunnel mode control system of a forklift and a narrow-tunnel forklift. Background The forklift is an industrial carrying vehicle, namely various wheeled carrying vehicles for loading, unloading, stacking and short-distance transportation of finished pallet cargoes, along with the development of industrialization and intellectualization, more and more enterprises tend to use the forklift with an automatic navigation function to replace manual carrying of cargoes, on one hand, the manpower cost can be reduced, no human error occurs, on the other hand, the forklift can continuously and efficiently work, the factory yield is improved, in the current narrow lane forklift field, a magnetic navigation mode is more and more common, and the roadway mode of the forklift means that after the narrow lane forklift enters a roadway, a driving wheel returns to the middle position and is kept, at the moment, a steering wheel is locked, and the vehicle can only linearly advance or retreat. In the prior art, in order to realize automatic switching roadway mode, the conventional practice is to install the card reader on the forklift chassis, the roadway ground punches and installs the card with parameters, when the card reader reads the card, an instruction is sent to the vehicle, the roadway mode is switched to, the existing card reader cooperates with the automatic switching roadway mode scheme realized by the card, the cost of using the card reader and the card is higher, the card needs to be installed on the ground in a punching way, a certain construction difficulty is achieved, and a certain damage is caused to the warehouse ground. Disclosure of Invention The invention aims to provide a tunnel mode control system of a forklift and a narrow tunnel forklift, so as to solve the problems in the background art. In order to achieve the above purpose, the present invention provides the following technical solutions: a roadway mode control system for a forklift, comprising: the two-dimensional code picture is posted on the inner side of an entrance of the roadway goods shelf and is used for providing indication information of the roadway; The two-dimension code scanner is fixed on the inner side of the forklift and used for reading two-dimension code information of the two-dimension code pictures and sending the two-dimension code information to the controller; the controller is electrically connected with the two-dimension code scanner and the forklift control system, and is used for receiving the two-dimension code information sent by the two-dimension code scanner, and sending a control instruction to the forklift control system after receiving the two-dimension code information so as to switch the forklift control system to a roadway mode; The guide rails are arranged on the ground at the bottom of the roadway in two relatively parallel; The guide wheel assembly is mounted on two sides of the bottom of the forklift in a height-adjustable mode and abuts against the inner side of the guide rail.
