Embodiment approach

[0046] According to one embodiment of the present invention, the driving device 2 includes a hydraulic driving mechanism, and the torque is obtained by detecting the pressure of the hydraulic driving mechanism. Alternatively, the driving device 2 may also be a motor. At this time, the torque of the driving device 2 may be obtained by detecting the current of the motor, so as to obtain the concrete slump. Specifically, such as figure 2 As shown, the hydraulic drive mechanism can be connected with a hydraulic detection tube 3, and a pressure detection device 4 is installed on the hydraulic detection tube 3, and the pressure of the hydraulic drive mechanism is detected by the pressure detection device 4. The pressure detection device 4 can be selected appropriately, for example, the pressure detection device 4 can be an electronic sensor or a pressure gauge. The installation method of the pressure detection device 4 is well known to those skilled in the art and will not be repe...

Abstract

The invention provides a water adding method which is used for adding water into a stirring barrel of concrete stirring and transporting equipment in the process of transporting concrete by the concrete stirring and transporting equipment. The water adding method comprises the following steps: 1), measuring and storing the slump degree of the original concrete; 2), measuring the slump degree of the current concrete after the preset time; 3), judging whether the slump degree of the current concrete is equal to that of the original concrete or not; and 4), if the slump degree of the current concrete is equal to that of the original concrete, returning to the step 2), and if the slump degree of the current concrete is not equal to that of the original concrete, adding water into the stirring barrel (1) and then returning to the step 3). By adoption of the method, a proper amount of water can be added into the stirring barrel, so the defect that the concrete quality and the pumpability are reduced caused by loss of water is overcome.

Description

technical field [0001] The invention relates to a water adding method, which is used for adding water to a mixing drum of the concrete mixing and transporting equipment during the process of transporting concrete by the concrete mixing and transporting equipment. Background technique [0002] Concrete mixer truck is a special vehicle for long-distance transportation of concrete. It installs a self-rotating mixing drum on the chassis of the car. The concrete in the mixing drum still needs to be stirred during the operation of the vehicle. It has dual functions of transportation and mixing. . When the concrete mixer truck has been transported for a long distance or waited for a long time on the construction site, the concrete in the mixing drum often loses moisture, and the moisture loss is more serious in hot weather or high temperature areas. Add water. The inability to accurately determine the amount of water to add results in the addition of too much or too little water,...
