Description

Intelligent production device for concrete pipe piles and production line using the device

Technical field

The invention relates to an intelligent production device for concrete pipe piles and a production line using the device.

Background technique

At present, the concrete pipe pile needs to be pumped and fed into the mold through a pumping pipe during the processing process. The pumping pipe needs to be inserted into the mold before starting to pump the material. After starting the feeding, the mold needs to gradually retreat according to the concrete conveying efficiency, and finally The mold is filled with concrete; but the existing pumping pipes are basically made of ordinary steel pipes, which have poor wear resistance and are prone to wear during the process of conveying concrete. Generally, the problem of excessive wear and pipe burst occurs after less than two months of use. , The pipe burst during the concrete pumping process directly causes the concrete to burst and scatter, affecting the construction environment, delaying the processing progress, and the pumping pipe needs to be replaced after the pipe burst, which causes a certain cost loss to the processing enterprise; and when the mold is internal When the concrete slump is unstable, the problems of excessive dryness and poor fluidity of concrete are prone to occur, especially the existing mold moving speed and law are set according to the normal slump of the concrete, and the movement of the mold is a fixed "foolish" When the concrete slump is unstable, the movement of the mold cannot be adjusted adaptively, and the inner holes of the existing pumping pipes are all set with equal diameters. As the concrete in the mold gradually accumulates, there will be a blockage problem. It directly leads to the failure of the pumping pipe to be dredged and scrapped. The blockage will also increase the load of the pump and easily damage the pump. The existing concrete pumping work has many defects, and multiple operators are required to keep an eye on each link during the construction process. Be prepared to deal with unexpected problems at any time, increase the labor cost of the enterprise, and the production efficiency is not high.

After the mold is finished feeding, it needs to be formed by a centrifuge. After centrifugation, the mold and the concrete pipe piles need to be put into the steam curing tank for steam curing. The general steam curing tank has a depth of more than 3 meters, a length of about 17 meters, and a width of nearly 3 meters. From left to right, the concrete pipe pile molds are put into or removed from the steaming tank and need to be lifted by crane. Although the crane is suitable for vertical lifting, the crane needs manual operation by the driver, and the driver's technical ability and sense of responsibility will be Affects the lifting of concrete pipe pile molds. During the lifting process, the molds are prone to mold impact due to the excessive falling speed, which leads to the damage of the concrete pipe piles inside the new molds and the molds are also prone to deformation due to impact Moreover, the frequent entry and exit of the molds in and out of the steaming tank are manually operated by crane operators. Unskilled operators often happen that the mold swings too much and collides with the side walls of the steaming tank, which damages the sealed water tank at the top of the steaming tank, causing Steam leaks, increasing maintenance costs. Existing steel pool covers are relatively large in mass and volume, and some weigh up to 6 tons. Frequent opening and closing of the cover will also cause collision and deformation due to operating errors. After the pool cover is deformed, the problem of tight closure and air leakage will occur. Summary of the invention

The invention provides an intelligent production device for concrete pipe piles and a production line using the device. The structure design is reasonable, the pumping pipe structure is reasonably improved, and the inner diameter of the concrete conveying adopts a unequal diameter design to reduce the pumping pipe and the concrete.

Compared with the equal-diameter design of the feeding channel 3 in the pumping pipe 2, concrete blockage is less likely to occur, and the impact of concrete on the inner wall of the pumping pipe 2 is reduced. The friction force of the load cell can reduce wear; and the overall weight of the mold 5 can be obtained in real time through the load cell 6 and transmitted to the controller. After the mold 5 moves to the load cell 6, the load cell does not start pumping concrete. 6 Transmit the initial weight of the mold 5 to the controller and record it. When the pumping starts, the concrete gradually fills the mold 5, the weight obtained by the load cell 6 gradually increases, and the controller subtracts the mold according to the real-time weight of the load cell 6 5 is the initial weight, the real-time concrete weight-M is obtained, using the weight-volume formula, M=ρ*πr ² *h, ρ is the density of the concrete, which can be measured in advance, r represents the radius size of the inner hole of the mold 5 (ie The radius of the concrete precast pile product), πr ² represents the cross-sectional area of the inner hole of the mold 5 (ie the area of the bottom surface of the concrete precast pile product), r can be obtained according to the specific model size of the mold 5, and h represents the length of the mold; using the above formula , Bring in the weight M measured by the controller, the value of h can be obtained, which represents the length of the concrete filled in the mold 5, so the controller can control the drive motor 7 to drive the platform 4 and the mold 5 to move adaptively to match accurately The pumping volume of concrete avoids the problem of blockage of the pumping pipe 2 caused by the mold 5 moving too slowly, and at the same time, the speed can be controlled to avoid the problem of insufficient pile compactness caused by the mold 5 moving too fast, which effectively reduces the concrete pumping The problem in the process improves production efficiency and does not require too much labor, which saves the production cost of the enterprise; after the feeding of the mold 5 is completed, it must be centrifuged to make the concrete raw material inside the mold 5 form a pipe pile. Move the mold 5 together with the concrete pipe pile to the curing device for steam curing. The mold 5 moves along the conveying channel 1. Before entering the steam curing unit, it can be statically cured on the conveying channel 1 and then enters the sealed cavity of the steam curing unit 11 Carry out steam curing. The whole process does not need to repeatedly lift the mold 5, just move the mold 5 to the feeding end 0 of the conveying channel 8. The mold 5 then moves along the conveying channel 8.
