1、 The incline device for detecting the vehicle levelness and the sensor for detecting the force on the outrigger. The tilt sensor can sense the vehicle levelness and send the horizontal angle information in real time, which can effectively avoid the vehicle rollover caused by the slow ground settlement. The function of the tilt sensor is to measure the vehicle tilt angle in real time. The measurement accuracy of inclination sensor is higher than 0. 05 degrees. It can filter out the tiny vibration caused by the vibration of the engine and pump. When the left and right angle is greater than 3 degrees or the front and rear angle is greater than 5 degrees, the alarm will be triggered.

二、支腿受力传感器实时检测各支腿受力情况，当某侧两个支腿受力都小于某一数值时及时发出警告或终止当前动作。需要补充的是人工智从来不是的，这种轴式重力传感器只能感应某一方向上的受力情况，由于泵送时整车晃动及支腿垂直度各异，检测到的受力情况真实性不够，存在误信号和漏信号的可能。

2、 The outrigger force sensor detects the force of each outrigger in real time. When the force of two outriggers on one side is less than a certain value, it will give a warning or terminate the current action in time. What needs to be added is that artificial intelligence has never been. This kind of axial gravity sensor can only sense the force in a certain direction. Due to the different shaking of the whole vehicle and the verticality of the outrigger during pumping, the authenticity of the force detected is not enough, and there is the possibility of false signal and missing signal.

作为现代化施工手段的混凝土泵车以其输送量大、输送速度快的特点，对于加快施工进度，缩短工期，降低施工成本，具有不可替代的作用。那么混凝土泵车选购和使用中应注意哪些事项呢？选购知名企业，产品质量有保证。通过生产企业的销售公司或该生产企业驻各地的销售办事处，索要查阅购买产品的鉴定证书、型式试验报告、专用车辆强检项目的检测报告及机动车辆目录号、质量体系认证证书等，派专人去生产企业考察其生产、管理和质量情况，作为选定商品的依据。根据承接工程的情况和该设备施工项目的大小、周期长短及转移频繁程度确定泵送方量、布料臂长度、布料臂参数和相适应的底盘。考察产品质量时应由表及里，是外观造型、涂装，焊缝钢结构件、走台、栏杆等是否平整光滑，美观流畅。

As a modern construction method, the concrete pump truck has the irreplaceable role in speeding up the construction progress, shortening the construction period and reducing the construction cost due to its characteristics of large conveying capacity and fast conveying speed. So what should be paid attention to in the selection and use of concrete pump truck? Choose well-known brands, product quality is guaranteed. Through the sales company of the production enterprise or the sales offices of the production enterprise in various places, ask for the identification certificate of purchased products, type test report, special vehicle compulsory inspection project test report, motor vehicle catalog number, quality system certification certificate, etc., it is better to send special personnel to the production enterprise to investigate its production, management and quality as the basis for selecting commodities. According to the situation of the project and the size, cycle length and transfer frequency of the equipment construction project, the maximum pumping volume, the length of the distribution arm, the parameters of the distribution arm and the suitable chassis are determined. Inspection of product quality should be from the outside to the inside, first of all, appearance modeling, painting, weld steel structure, walking platform, railing, etc. whether smooth, beautiful and smooth.

再逐步深入到内部，底盘发动机、变速箱、分动桥、主要液压元件、泵送系统、布料臂、回转机构和回转支承等配套件的性能质量。考察产品的使用性能，各部分动作的平稳性、灵活性、伸展布料臂和回收布料臂是否有不正常抖动，底盘行驶、转弯直径、接近角、离去角、小离地间隙等是否满足通过性要求，发动机的燃油消耗率等经济指标是否合理、遥控器操作是否可靠、稳定。对自制布料臂的产品还应仔细了解其结构件的制造质量。

And then gradually into the interior, chassis engine, gearbox, transfer axle, main hydraulic components, pumping system, distribution arm, slewing mechanism and slewing bearing and other accessories. The use performance of the product, the stability and flexibility of each part of the movement, whether the spreading arm and the recycling arm have abnormal shaking, whether the chassis driving, turning diameter, approach angle, departure angle and minimum ground clearance meet the trafficability requirements, whether the economic indicators such as engine fuel consumption rate are reasonable, and whether the remote control operation is reliable and stable. For the products of self-made cloth arm, the manufacturing quality of its structural parts should be carefully understood.

为了减轻布料臂、底架、支腿重量，其钢材均应采用高强度细精粒结构的碳素钢(调质薄钢板)，其焊接工艺要求十分严格，否则会出现焊缝开裂等十分严重的问题。检查产品的性和要求，核对专用车辆强检项目、制动性能、排放指标、噪音限值是否符合各标准要求。考察供货企业的售后服务网点是否能满足及时服务，以及服务质量、服务水平、零配件及时供货的能力。了解供货企业对客户的驾驶员、机手和维修保养人员的操作培训和维护保养培训承诺的情况。

In order to reduce the weight of distribution arm, underframe and outrigger, carbon steel (quenched and tempered steel sheet) with high strength and fine grain structure should be used. The welding process requirements are very strict, otherwise the weld cracking and other serious problems will occur. Check the safety and environmental protection requirements of the products, and check whether the compulsory inspection items, braking performance, emission index and noise limit value of special vehicles meet the requirements of various standards. To investigate whether the after-sales service outlets of suppliers can meet the requirements of timely service, as well as the ability of service quality, service level and timely supply of spare parts. Understand the supplier's commitment to the operation training and maintenance training of the customer's drivers, operators and maintenance personnel.
