[Detailed Description of the Invention] [Industrial Application Field] The present invention is aimed at realizing appropriate concrete pumping based on concrete pump usage conditions such as concrete slump, pipe diameter, etc. in pumping concrete to a concrete placement site. This invention relates to a concrete pump pumping condition confirmation device for determining necessary conditions.

[Conventional technology] Concrete pumps are divided into various models depending on their capacity, depending on the conditions at the concrete placement site, the hardness and slump of the concrete being pumped, the amount of concrete discharged, and the length of concrete piping. By knowing the amount of concrete to be discharged and the distance that concrete can be pumped depending on the conditions of use such as This is necessary and important in concrete pouring work.

In the past, for example, once a model was decided, if the model was to be used to pump 100 meters, it was necessary to determine what discharge amount, pumping resistance, concrete pipe diameter, etc. Usually, the pumping conditions are known.

[Problems to be Solved by the Invention] However, it is not easy to know the pumping conditions from the usage conditions, and there is a possibility that the machine cannot be used under conditions that match its performance.

The present invention makes it possible to know the discharge amount, maximum pumping distance, pumping resistance, etc. from the usage conditions such as the model, concrete piping, concrete mix, etc., and to select the model to be used, model performance,
This was done in an effort to create a device that would allow easy knowledge of pumping conditions, etc., so that it could be used in models with insufficient capacity.

[Operation] You can input various usage conditions, so
Based on the input usage conditions, the maximum pumping distance in the horizontal direction, the pumping resistance, the maximum pumping distance in the vertical direction, the pumping resistance, etc. are used to calculate the capabilities of the model to be used, and the calculation 1
Since the direct output is output, it is possible to select a model, judge the performance of the model, and know the conditions for enabling pressure feeding.

For model (■), the grade is the data.

The concrete piping conditions (2) include data such as the pipe diameter, horizontal pipe length, vertical pipe length, inclination angle, number of bent pipes, length of the end hose, and type of tapered pipe.

The concrete mixing conditions of Concrete! type of ~, specific gravity of concrete, type of cement, coarse particle ratio of fine aggregate, specific gravity, water absorption rate and O, content of fine bones of 3mm or less, type and origin of fine bones (A type and origin, type and origin of coarse aggregate, The data includes the coarse particle ratio, specific gravity, water absorption rate, type of admixture, etc. of fine aggregate.

In addition, the il isolation device 3b of the arithmetic circuit 3 performs calculations to determine the maximum horizontal distance that can be pumped, calculations to determine the pumping resistance for the specification conditions input to the input circuit 1, calculations to determine the required pumping time, and the amount of concrete in the pipe. The calculation device 3C performs calculations to determine the maximum distance that can be conveyed by standing pressure, calculations to determine the pumping resistance for the operating conditions input to the input circuit 1, calculations to determine the required time for pumping, and calculations to determine the distance in the piping. This is to calculate the amount of concrete, and when the selector 3a divides it into a horizontal part and a vertical part, in the case of a horizontal part, the calculation device 3b performs the above calculation based on the signal from the calculation selection circuit 2. In the case of a vertical portion, the above calculation is performed by the calculation device 3C.

The discriminator 3d examines the pumping conditions from the values calculated in steps 3b and 3c above. Type, pressure feeding capacity per time, pipe diameter, slump, water absorption capacity, unit cement capacity, unit water volume, 0
We examined the following: ratio, type of coarse aggregate, coarse grain ratio of coarse aggregate, type of fine aggregate, coarse grain ratio of fine aggregate, content of fine aggregate of 0.3 mm or less, temperature, etc. It is designed to output pumping conditions for each different usage condition.

The output circuit 5 has a function of displaying the relationship between the discharge amount and the maximum pumping distance as a result of thrift based on the study by the discriminator 3d of the W circuit 3, and a function of displaying the relationship between the discharge amount and the maximum pumping distance for the input usage conditions. A function to display the relationship, a function to graph the two different relationships above, and conditions to enable pumping when the pumping conditions are not met, for example, how to set the concrete mixing conditions, concrete There is a function to determine the piping conditions, what model to use, what kind of equipment to use, what are the operating instructions, etc., and the function to determine the model and concrete to enable the above-mentioned pressure feeding. -1 ~ The configuration includes a function to create an estimate of how much it will cost to change piping, spare parts, attached equipment, etc.

Now, for example, when values consisting of the capacity of the model, concrete piping conditions, and concrete mixing conditions are input into the input circuit 1, the maximum pumpable distances in the horizontal and vertical sections are determined by the calculation condition selection circuit 2 and the calculation circuit 3. Pumping resistance etc. are determined separately. The pumping conditions are examined in the discriminator 3d from this determined value. For example, if the pumping resistance and the capacity of the model are calculated, if the pumping conditions determined in this examination are not changed, the pumping conditions are left as they are. into the output circuit 5. In the output circuit 5, the relationship between the discharge amount and the maximum possible pumping distance is displayed based on the above-mentioned pumping conditions, and the input circuit 1
If the capacity of the machine you input is displayed, the capacity of the machine you want to use will be displayed, indicating how far it can pump. For example, the capacity of the model input to the input circuit 1 is 300.
If you want to pump a distance of m, and the maximum pumpable distance displayed in the output circuit 5 shows that it can be pumped up to 200 m, then change the concrete mixing conditions according to the conditions to enable pumping, which are displayed at the same time in the output circuit 5. You can learn how to modify pumping conditions such as concrete piping conditions to enable pumping up to 300 m using the above-mentioned model. In this way, when you want to use the following models, the maximum pumping distance that you most want to know is displayed on the output circuit 5 according to the input usage conditions, and if this is less than the actual pumping distance, what are the pumping conditions? If so, it is possible to know the actual pressure-feeding distance, and at the same time, the selection of a model that can perform pressure-feeding is also performed at the same time as to determine which model is better if the model is to be changed. Furthermore, in the output circuit 5, when the pumping conditions are calculated from the input usage conditions and displayed, the ability (performance) of the model used is determined as described above, the relationship between the discharge amount and the maximum pressure-feedable distance, and the relationship between the discharge amount and the It is clear from the relation of pumping resistance, how much it costs to make a pumping line fl to compensate for the lack of capacity, and how much it costs to make a model that satisfies the pumping conditions when changing to a different type. Since estimates such as , etc. are also created, it is possible to deal with the problem quickly.

In addition, if you want to change the pumping conditions considered by the arithmetic circuit 3, for example, if you want to know the pumping conditions when changing the model input to the input circuit 1 to another model, input from the pumping condition changing section 4. The pumping conditions are fed back to circuit 1 and input again. As a result, R-appropriate pumping conditions are calculated again from the usage conditions.
