Description

Steering transmission mechanism with rudder stock angle monitoring function Technical Field The utility model relates to the technical field of material handling, in particular to a steering transmission mechanism with a tiller angle monitoring function. Background Material handling refers to activities performed within the same field category that are primarily targeted to changing material storage status and spatial location. Materials handling is important for improving warehouse operation efficiency and also directly affects production efficiency. In a production enterprise, a logistics manager is generally responsible for links such as goods carrying and warehousing, goods storage in a warehouse, movement of goods from a storage place to an order sorting area, and finally reaching a goods-out area to prepare for delivery to the warehouse. The existing forklift steering transmission mechanism generally adopts an independent angle sensor to monitor the angle of a tiller, and the problem that the installation positions of the sensors are scattered and signals are easy to be interfered by mechanical vibration exists. Based on the above, the utility model designs a steering transmission mechanism with a rudder stock angle monitoring function so as to solve the above problems. Disclosure of utility model The utility model aims to provide a steering transmission mechanism with a rudder stock angle monitoring function, so as to solve the technical problems. The steering transmission mechanism with the rudder stock angle monitoring function comprises a shell, wherein one side of the shell is provided with a mounting seat, a sensor base is arranged on the mounting seat, a control board is arranged in the sensor base, a wire harness is connected to the control board, a lower bearing is arranged on the shell, a steering shaft is arranged in the lower bearing, a magnet mechanism is sleeved on the outer side of the steering shaft, a damper is further arranged on the steering shaft, and an upper bearing is further arranged on the outer side of the top of the steering shaft. By adopting the technical scheme, the integrated installation of the sensor and the control panel is realized, and the signal transmission interference is reduced. Preferably, the steering shaft is provided with a limiting groove, and a limiting check ring is arranged at the limiting groove on the steering shaft. By adopting the technical scheme, the axial displacement of the steering shaft is limited, and the influence of the offset of the magnet mechanism on the monitoring precision is prevented. Preferably, the magnet mechanism comprises a first magnetic ring and a second magnetic ring, the radians of the first magnetic ring and the second magnetic ring are larger than 90 degrees, two ends of the first magnetic ring and the second magnetic ring, which are in mutual contact, are opposite to each other, and a positioning groove for installing the magnet mechanism is further formed in the outer wall of the steering shaft. By adopting the technical scheme, the split type magnetic ring is convenient to assemble and position, and after combination, the split type magnetic ring covers a monitoring range of more than 180 degrees, so that the signal capture of the full steering angle is ensured. Preferably, a wave washer is further arranged between the steering shaft and the damper. By adopting the technical scheme, the axial gap between the damper and the steering shaft is eliminated, and the vibration resistance is enhanced. Preferably, the bottom end of the steering shaft is connected with a cylindrical pin, and the steering shaft is connected with the tiller through the cylindrical pin. By adopting the technical scheme, the rigid power transmission of the steering shaft and the tiller is realized, and the relative sliding is avoided. Preferably, a plurality of ear plates are further arranged on the outer side of the shell. By adopting the technical scheme, the multi-bolt mounting interface is provided, and the overall stability of the mechanism is enhanced. In summary, the application has the following beneficial technical effects that the angle monitoring anti-interference capability is improved through the coaxial integrated design of the arranged magnet mechanism and the control board, the assembly complexity is reduced and the magnetic field stability is ensured through the combination of the arranged split type magnetic ring and the positioning groove structure, and finally the monitoring error caused by the shaking of the steering shaft is obviously reduced through the arrangement of the double-bearing support matched damper.
