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.
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.
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.
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.
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.
