Problems solved by technology

Concrete mixing, transportation and construction parties are often three different units, which are usually measured by the capacity of the concrete mixer truck or the pumping time, but the actual working process of the concrete pump does not pump with a full volume each time, which is not accurate. The real-time measurement system of concrete pump displacement makes it difficult for the three parties to distinguish the fair trade among them. At the same time, there is no reliable basis for the monitoring of the operation status of concrete pumps or pump trucks, construction management and evaluation of construction quality and pump truck quality

Embodiment Construction

[0025] As shown in Fig. 2, Fig. 3, Fig. 4, the present invention comprises pressure sensor 12, displacement sensor 14, position sensor fixed support 18, fixed pulley 17 and signal acquisition card 13; On the oil and oil road; the displacement sensor 14 is fixedly mounted on the water tank 10 with a bracket, and 11 is a cooling water pipe. One end of the displacement sensor 14 is fixed on the piston of the same concrete pump piston rod 5 as the pressure sensor 12 through the displacement sensor steel wire 15 and the fixed pulley 17. The rod is connected to the flange 16 end faces, the other end of the pressure sensor 12 and the displacement sensor 14 is connected to the signal acquisition card 13, and the measured analog signal is input into the computer software by the signal acquisition card;

[0026] The displacement sensor 14 is fixed on the support 10, the displacement sensor steel wire 15 is in the same vertical plane as the center line of the piston rod 5 and the center o...

Abstract

The present invention discloses a method for measuring concrete pump output and its equipment. Said method includes the following steps: making one end of pressure sensor be mounted on the oil-feeding oil circuit of hydraulic oil cylinder; fixing and mounting the displacement sensor on the water tank by means of supporting frame; making one end of displacement sensor be fixed on the end surface of piston rod connection flange of concrete pump piston rod, another one ends of pressure sensor and displacement sensor are respectively connected with signal collecting card; then inputting the measurement analogue signal into computer software by means of signal collecting card; utilizing pressure sensor and displacement sensor to simultaneously measure pressure of concrete pump hydraulic oil cylinder and concrete cylinder piston stroke; utilizing pressure signal to trigger concrete pump piston displacement signal removing concrete pump piston idle stroke so as to obtain concrete pump effective displacement and can obtain the actual output of concrete pump.

Description

technical field [0001] The invention relates to a method and a device for measuring the displacement of a concrete pump. Background technique [0002] With the great development of all kinds of industrial and civil infrastructure, the number of domestic and imported concrete pumps or pump trucks in my country is increasing, and the way of use is also changing. In order to improve construction efficiency and avoid construction disturbance, concrete mixing is carried out at the mixing station. The distance between the mixing station and the construction site is relatively long, and each construction site is different. The intermediate concrete transportation link is completed by concrete mixer truck. Concrete mixing, transportation and construction parties are often three different units, which are usually measured by the capacity of the concrete mixer truck or the pumping time, but the actual working process of the concrete pump does not pump with a full volume each time, whi...
