Anti-rollover device for cement pump truck

Abstract

The invention discloses an anti-rollover device for a cement pump truck. The anti-rollover device comprises a microcomputer, an analog-to-digital converter, a hydraulic system switch, an alarming device, hydraulic sensors and support oil cylinders, wherein the microcomputer, the analog-to-digital converter, the hydraulic system switch and the alarming device are installed on the operating panel of the cement pump truck; the microcomputer is respectively connected with the analog-to-digital converter, the alarming device and the hydraulic system switch through data lines; and the hydraulic sensors are installed on the support oil cylinders and are connected with the analog-to-digital converter through data lines. During operation, the pressure change situations of the support oil cylinders are monitored in real time through the hydraulic sensors; if the pressure change value exceeds a safety value, the microcomputer gives out a command to the alarming device and the hydraulic system switch, the alarming device gives out an alarm, the hydraulic system switch is turned off and the cement pump truck stops working; and if the pressure change value does not exceeds the safety value, the cement pump truck operates continuously. The anti-rollover device for the cement pump truck has the advantages that the pressure change situations of the support oil cylinders can be monitored in real time, the cement pump truck is effectively prevented from rolling over and the practicability is very high.

Description

technical field [0001] The invention relates to an engineering mechanical device, in particular to a device for effectively preventing a cement pump truck from turning over. Background technique [0002] At present, due to the wide variety of cement pump trucks, they have been widely used in various fields and play an extremely important role in various fields. [0003] However, in practical applications, due to the complex environment of the construction site, when working on rough or soft ground, the four legs of the cement pump truck must be kept horizontal when extending, rotating or moving the boom, otherwise , the cement pump truck will be in danger of rollover. [0004] In addition, because most operators are sitting in the operating room, they have limited knowledge of the actual situation on the ground. Therefore, in practical applications, rollover accidents of cement pump trucks often occur, causing countless personnel and property losses. [0005] To sum up, in...

[0003] However, in practical applications, due to the complex environment of the construction site, when working on rough or soft ground, the four legs of the cement pump truck must be kept horizontal when extending, rotating or moving the boom, otherwise , the cement pump truck will be in danger of rollover

[0004] In addition, because most operators are sitting in the operating room, they have limited knowledge of the actual ground conditions. Therefore, in practical applications, cement pump truck rollover accidents often occur, causing countless personnel and property losses.

[0005] To sum up, in order to ensure that the cement pump truck can achieve safety and reliability during operation, it is necessary to effectively detect the pressure data of each outrigger cylinder of the cement pump truck, otherwise, once a rollover accident occurs, it will inevitably lead to With a series of rising costs and slowing down of construction progress, a device that effectively prevents the cement pump truck from turning over has become particularly important at present
