Detecting test bed used for engineering truck maneuvering box

Abstract

A detecting test bed used for an engineering truck maneuvering box comprises an electric cabinet (15). A universal meter tray (13), a display instrument panel (14) and an operation panel (16) are arranged in the electric cabinet (15). The detecting test bed is characterized in that a first series circuit and a second series circuit are connected in parallel and are controlled through a micro-switch (1), a travel switch below an armrest box operation rod on the engineering truck maneuvering box is connected with the micro-switch (1), the two series circuits can be controlled to work by simply rotating the operation rod, and therefore whether the movement of the operation rod is in place or not and whether connectors are inserted correctly or not can be indicated. The detecting test bed can detect the voltage value corresponding to each gear on the condition that a potentiometer is in fixed voltage, can detect whether the movement of the operation rod is reliable or not and whether the wrong insertion condition or the reverse connection condition exists in relevant connector interface sequence numbers or not and brings convenience to operation and detection.

Description

technical field The invention relates to the structure of a detection test bench for a control box of an engineering vehicle. It is used for the detection of the control box in the cab of the construction machinery. Background technique In today's rapid economic development, all walks of life have undergone earth-shaking changes. In the past, although there were some simple tools for building houses and roads, the main method was still relying on the shoulders of manpower. Now all kinds of large-scale machinery are widely used , liberate manpower and improve productivity. Why can these bulky and large-scale mechanical equipment complete complex tasks? The fundamental reason is to use hydraulic control and electric control to make these bulky big guys more flexible. In order to allow the operator to control the hydraulic system and the power system better and more conveniently, the designers designed the armrest box, which integrates the hydraulic control device and the ele...
