The design steps of the maximum value of the distance and the preparation starting time of the concrete are as follows:
s1, calculating the maximum value of the distance according to the mixing time, the transportation speed and the vibrating time.
The step S1 specifically comprises the following steps:
s11, determining and configuring one concrete average time T according to the mixing capability of the mixing station Mixing In the embodiment, the HZS90 type mixing station is adopted, the mixing station is suitable for mixing 1.0 part of concrete, the mixing time is not less than 120s, and the mixing time is combined with calculation of the mixing time, and the average time T of concrete is calculated for each part of mixing Mixing ＝150s。

And S3, calculating the relation between the time for starting the preparation of the concrete and the residual weight of the concrete in the distributing equipment 3.
In the actual production process, the waiting time T appears after each preparation single cycle Waiting for . Since the castable modulus of each concrete is not an integer, the residual amount in the distributing device 3 after each preparation single cycle is different, T Waiting for Also each time, and as such, the weighing device 4 is required to monitor the residual storage amount of the concrete in the distribution device 3, and different preparation starting time of the concrete is selected according to the residual storage amount in the distribution device 3, so that the waiting time T Waiting for Within a reasonable range. If T Waiting for Too short time, the concrete preparation single cycle is ended too early, if the concrete is directly discharged into the material distribution equipment 3, the acting force on the stirring shaft is increased due to too much stock of the material distribution equipment, so that the stirring shaft cannot be normally operated, is stopped for protection and is even forced to rotate to be damaged, further, the upper concrete is lost in water to be dried, the stirring shaft is more difficult to operate, and the stirring shaft falls into vicious cycle. If the concrete is retained in the transportation equipment, too much residues accumulated on the inner wall of the transportation equipment are difficult to clean, the equipment can be opened and closed to a door, and in addition, the phenomenon of water loss of the concrete can be caused due to the fact that the transportation equipment is additionally provided with an oil pump to generate heat. If T Waiting for The production efficiency is directly affected when the time is too long, and the equipment is difficult to open and close.
The step S3 specifically comprises the following steps:
s31, starting to stir the concrete until the carrier is discharged to the material distributing equipment to form a single preparation cycle, and calculating the time T required by the single preparation cycle according to the selected specific distance value Circulation In the present embodiment, the specific distance is based on the on-site production, and the distance is between 0 and 19.5, 160s < T Circulation ＜200s。
S32, the ratio of the concrete pouring amount to the concrete consumption of a single die in one preparation single cycle is m;
s33, rounding the ratio m downwards to an integer m 1 The ratio m is rounded up to an integer m 2 In the present embodiment, T is the normal condition of the equipment operation Circulation Can only finish the cloth process of 2 moulds in time, then m 1 ＝2，m 2 ＝3。
S34, the concrete storage in the distributing equipment is G Storing the articles The concrete dosage of the single die is G Single mode Then when G Storing the articles Satisfy m 1 ×G Single mode ＜G Storing the articles ＜m 2 ×G Single mode At this point, the mixing station begins to prepare concrete.
In this embodiment, the process of distributing the materials by the material distributing device 3 is divided into two times, not all the materials are distributed in the whole 100S process, the first material distribution is performed immediately after the process is started, about 10S, that is, the upper layer hopper distributes materials to the lower layer hopper, the first material distribution is performed after the weight of the lower layer hopper is reached, and the first vibration process is performed after the first material distribution. When vibrating, the upper hopper of the material distribution device 3 divides materials for the second time to the lower hopper, and when the first vibrating is finished, the lower hopper distributes the divided materials for the second time, so that the material distribution device 3 completes the material distribution task, and the material distribution time is within 60S. The single mode is used for taking 100S for calculation, the rest 40S is the continuous vibrating time after the second cloth, and the next station can be accessed after the second vibrating is completed. When 160s < T Circulation When the material distribution of the 2 moulds can be completed within 160S to 200S, and therefore, when the residual material quantity in the material distribution equipment 3 is larger than that of the 2 moulds, the material distribution of the lower hopper, which is caused by insufficient residual material of the upper hopper, can not occur in the process of mixing and transporting, and the consequence that the second material distribution can not be performed after the first vibration is finished can be ensured, so that the process time is directly prolonged, and the whole process time is delayed; in addition, when the residual material amount of the material distribution device 3 is larger than that of the material of the 3 dies, the material is mixed, when the material is stored in the material distribution device 3 in a mode of being larger than 1 die, the new material is mixed and enters a waiting stage, especially in summer construction, the initial setting time of C60 concrete is short, the waiting time can influence the quality of the concrete, and meanwhile, the waiting time is carried outThe material storage in the middle also can cause the increase of the load of the material stirring and discharging equipment in the material distributing equipment 3, and equipment damage is very easy to cause, so that the material stirring is carried out when the material stirring and transporting is carried out in less than 3 moulds, and when the material stirring and transporting are carried out, the material left in the hopper at the upper layer of the material distributing equipment is less than 1 mould, and the concrete just stirred can be immediately used to be in the optimal state. That is, when 2G Single mode ＜G Storing the articles ＜3G Single mode When the mixing station starts to prepare concrete, the concrete weight of the concrete is 2450kg according to the single C60 concrete weight, and when one pouring vibration single cycle is finished, the concrete storage amount G of the upper hopper of the material distribution equipment 3 Storing the articles The concrete preparation single cycle is started between 1750 kg and 2625kg, and the concrete preparation single cycle is the most reasonable concrete preparation starting time.
According to the invention, through reasonably designing the maximum value of the transport distance and the preparation starting time of the concrete of the composite concrete transport system, operators of the mixing station can select the preparation starting time of the concrete according to the residual weight of the concrete in the distributing equipment 3 monitored by the weighing equipment 4, so that the concrete waste caused by improper manual operation is solved, meanwhile, the production continuity is ensured, the production efficiency is improved, and the equipment failure rate is reduced.
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the invention in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present invention.
