Description

Mechanical interlocking double-pedal mechanism Technical Field The utility model relates to the technical field of forklifts, in particular to a mechanical interlocking double-pedal mechanism. Background In the field of industrial transportation, forklifts are widely used as important logistics equipment, and the operation and control modes of the advancing directions of the forklifts directly influence the operation efficiency and the operation safety. At present, a control mode of combining an accelerator pedal with a forward/backward reversing deflector rod is commonly adopted by a traditional forklift. Specifically, the driver switches the reversing shift lever to a forward or backward gear and presses the accelerator pedal to control the traveling direction of the forklift. However, this manner of manipulation has a number of disadvantages. Firstly, a driver needs to pay attention to the position of the reversing deflector rod and the stepping of the accelerator pedal in the operation process, the operation steps are complicated, particularly in a high-strength and high-frequency operation environment, the attention is easy to be dispersed, and further the operation errors are caused, so that the working efficiency is reduced. For example, when loading and unloading operations are frequently performed in a narrow warehouse, a driver needs to frequently switch a deflector rod and accurately control an accelerator pedal, so that the operation difficulty is remarkably increased, and the error probability is increased. Secondly, from the aspect of safety, because the reversing deflector rod and the accelerator pedal are two independent operation parts, an effective interlocking mechanism is lacked, misoperation is easy to occur, in an emergency, a driver can mistakenly step on the accelerator pedal under the condition that the shift position of the deflector rod is not confirmed, and the driving direction of a forklift is opposite to that of the accelerator pedal, so that safety accidents such as collision are caused, safety of personnel and goods is seriously threatened, and the mechanical interlocking double-pedal mechanism is provided. Disclosure of utility model The present utility model is directed to a mechanical interlocking dual pedal mechanism to solve the above-mentioned problems. In order to achieve the purpose, the mechanical interlocking double-pedal mechanism comprises a coaming connected with a vehicle body, wherein toothed plates are rotatably connected to the coaming, a forward pedal and a backward pedal meshed with the toothed plates are respectively arranged on two sides of the toothed plates, and when one pedal is stepped on, the toothed plates meshed with the toothed plates are driven to rotate by the pedals, and then the other pedal is driven to be lifted by the rotating toothed plates.
