Fork lifting lever mechanism

Abstract

The invention provides a fork lifting lever mechanism which comprises a bracket fixed at the outside end of an inner fork of a fork of a shuttle vehicle, a direct current motor arranged on the bracket, a lifting lever which is positioned at the front end of the bracket and is in transmission connection with the direct current motor, a circuit board arranged at the front end of the bracket, and a magnet arranged at the tail end of the lifting lever, wherein the circuit board is provided with a singlechip microcomputer, a power supply module, a hall sensor I, a hall sensor II and a direct current motor driving module; after the lifting lever arrives at a proper position, the singlechip microcomputer is capable of transmitting signals to the direct current motor driving module by virtue of feedback signals of the hall sensor I and the hall sensor II, so that the direct current motor stops rotating. Since the circuit board of an overall control system is fixed to the bracket, the singlechip microcomputer of the circuit board is connected with an upper computer through a communication cable, so that the routing complexity is greatly reduced, the cost is lowered, and the use reliability of the fork of the shuttle vehicle is improved.

Description

technical field [0001] The invention relates to a pallet fork lever mechanism. Background technique [0002] The swing rod installed on the inner fork of the existing shuttle truck fork to hook the turnover box and move to the shuttle car body with the fork is generally driven by a motor. The swing rod is in the vertical state and the horizontal state. The in-position detection of the state is detected by the photoelectric switch. Since each photoelectric switch and the motor need to be connected to the upper computer with a cable, the number of cables is very large, and the drag chain is required, which greatly increases the production cost. At the same time, the drag chain is easily damaged. It affects the reliability of the shuttle fork. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a pallet fork lever mechanism that reduces the number of control cables and improves reliability.
