Description

Technical Field

[0001] The present invention belongs to the technical field of automated pipe pile production, and specifically relates to an automated production line for pipe pile production and an automated production method thereof. Background Art

[0002] Cement pile production is a labor-intensive enterprise. Traditional cement pile production lines have high labor intensity, low work efficiency and many safety hazards. Especially in the mold disassembly and assembly area, multiple processes such as hanging the upper mold, removing the screws of the upper and lower molds, removing the head and tail plates of the cement pile, removing the upper cover mold, demoulding and hanging the cement pile, cleaning the upper and lower molds, installing the head and tail plates, and installing the steel cage into the lower mold are intertwined. People working together need to avoid each other.

[0003] The method adopted by the automatic production line of pipe piles is to cover the cover mold on the bottom mold, and then set cage reinforcement between the bottom mold and the cover mold. After the material is formed between the bottom mold and the cover mold, the bottom mold and the cover mold are connected by the mold bolts. After the tensioning-centrifugal-steaming process, the finished pipe pile is obtained. The main process of the existing production line is material laying-mold closing-tensioning-centrifugal-steaming-demolding-cover mold cleaning, spraying mold release agent-cleaning bottom mold, spraying mold release agent-lifting cage reinforcement-laying. The degree of automation of this production line is not high, and the demand for labor is relatively large. The pipe mold is transported by flat car, which is inefficient and greatly restricts the improvement of production capacity. The transportation of pipe molds across workshops is carried out by crane. The demand for cranes during transportation is large, which restricts the maximization of production capacity. When the pipe mold is running by the crane, it is usually placed on the ground, and then the mold is manually cleaned, the mold release agent is sprayed, and the pile is hung. The demand for labor is large. The flat car transportation of pipe molds is mainly single-line transportation, and the pipe mold needs to be transported from one workshop to another, and then back. Repeatedly, there is a waste of time and production capacity.

[0004] Most of the existing highly integrated pipe pile production lines not only compress the distance between operating equipment to maximize the use of factory buildings, but also require manual operation in these equipment. Under such a greatly compressed operating space, it is very easy for the operation of the equipment to cause accidental injuries to personnel. Especially when the cage reinforcement needs to be hoisted into the bottom mold after assembly, manual calibration and positioning are required. In order to optimize the production efficiency of cleaning, spraying and assembly between the bottom mold, cage reinforcement and cover mold, most of the existing ones set the demoulding and cleaning of the bottom mold together. After cleaning, the cage reinforcement and cover mold are hoisted and assembled in turn by crane. In this process, whether it is transportation, cleaning or spraying of release agent, the equipment inside is large-scale equipment in operation. If there are always people moving and hoisting around it, they will not pay attention to other equipment in the area because of their attention on hoisting, which will cause personnel danger and accidents.

[0005] Therefore, there is a need for a pipe pile production line and its operation method that can maximize the realization of automated production combinations, keep personnel as far away from the production line where the automated combination operates as possible, and ensure the safety of personnel.

The bottom mold cleaning and mold closing can be completed without manual operation, thereby reducing labor costs and personnel risks.

[0011] The cage reinforcement conveying and unloading component is a suspended cage reinforcement longitudinal conveying device, which is hoisted and moved by the cage reinforcement crane and the cage reinforcement production station.

[0015] The pipe pile production is set up in workshop A, workshop B, workshop C and workshop D. The workshop A is equipped with workstations for tensioning, pumping, centrifugation, steaming and unloading. The workshop B is equipped with workstations for removing mold bolts, uncovering cover molds and cleaning cover molds. The workshop C is equipped with workstations for turning over piles / rods, cleaning bottom molds, placing cage reinforcements, closing cover molds and closing mold bolts. The workshop D is equipped with a workstation for storing finished piles / rods. The specific automatic production method is as follows;

[0016] The pumping metering flat car automatically distributes the material into the mold, and the filling centrifugal crane lifts the pumped mold to the centrifuge for centrifugation; the steaming transfer crane is used to lift the mold that has been centrifuged in the centrifuge to the steaming tank for steaming; the steaming transfer crane then lifts the steamed mold in the steaming tank to the horizontal chain unit for out-of-tank. At this time, the detection switch detects that the mold starts the drive motor. After the mold is transported horizontally to the lifting station, the out-of-tank lifting and translation unit lifts the mold and transports it to the out-of-tank longitudinal scale chain unit. After detecting that the mold has reached the top of the out-of-tank longitudinal scale chain unit, the out-of-tank lifting and translation unit begins to descend to place the mold stably on the out-of-tank longitudinal scale chain unit; the mold is transported by the out-of-tank longitudinal scale chain unit of workshop A. The upper longitudinal chain machine of workshop B conveys the mold to the upper longitudinal chain machine of workshop B. During this conveying process, the bolts for closing the mold are removed by the automatic mold removal bolt device. When the mold reaches the designated position, the automatic cover mold uncovering device automatically uncovers the cover mold of the mold and transfers it to the horizontal cover mold chain machine. After the cover mold is automatically uncovered, the bottom mold is simultaneously transported to the car C through the upward longitudinal chain machine. The cover mold in workshop B is conveyed by the horizontal cover mold chain machine. During this process, the cover mold will be cleaned and the mold release agent will be automatically sprayed. The cover mold is conveyed to the bottom of the cover mold longitudinal conveying device and then transported to workshop C through it. The cage reinforcement crane in workshop B lifts the finished cage reinforcement to the cage reinforcement longitudinal conveying device and transports it to workshop C. The bottom mold in workshop C is transported by the demoulding longitudinal scale plate chain machine to the designated After the bottom mold is in position, the demoulding jacking and translation unit will jack it up and transport it to the automatic bottom mold turning device for pile / rod turning; after the pile / rod turning is completed, the empty bottom mold will be jacked up by the demoulding jacking and translation unit and transported to the bottom mold transverse chain unit; the internal pile and rod crane of workshop C will lift the pile / rod that has been turned over to the bottom on the buffer rack to the electric pile-out vehicle; the bottom mold will be cleaned and automatically sprayed with a release agent when it is transported on the bottom mold transverse chain unit. When the bottom mold is transported to the designated position, the cage reinforcement longitudinal conveying device will place the cage reinforcement transported from workshop B into the bottom mold from top to bottom; after the bottom mold and cage reinforcement combination are transported to the bottom of the cover mold longitudinal conveying device, the cover mold longitudinal conveying device will place the cover mold transported from workshop B from top to bottom on top of the bottom mold for automatic mold closing. ; After mold closing, the mold is lifted and transported to the mold closing longitudinal scale plate chain unit by the mold closing jacking and translation unit, and then transported from workshop C to workshop B; the mold after mold closing is locked by the automatic mold closing bolt device, and then transported by the downward longitudinal chain machine in workshop B to the packing longitudinal scale plate chain unit in workshop A; after the mold arrives at the designated position in workshop A, the packing jacking and translation unit lifts it to the tensioning transverse chain unit for transportation, and a tensioning station is set in this process; the tensioned mold is lifted and transported to the buffer table of the pumping and metering flat car device by the packing centrifugal crane, and then lifted and transported to the metering flat car by the jacking and translation trolley of the pumping and metering flat car device for pumping and distributing, and the above working principle is repeated for cyclic production.

[0017] Beneficial effects:

[0018] By performing fixed positioning operations at each workstation, most of the production effects of automated lifting and transfer can be achieved, which not only reduces the number of overhead cranes, but also enables maximum automated production. The fixed workstation format can effectively ensure the stability of automated lifting and placement, thereby achieving efficient and high-quality automated production, and effectively reducing possible injuries to personnel during the operation of overhead cranes and chain machines, reducing the risk of accidents.

[0019] The mold-closing filler conveying assembly is used to transport the completed pipe pile mold across the workshop, and the outer locking bolts are automatically locked and fixed, and the transfer and tensioning are completed efficiently. Finally, the mold is hoisted and pumped, thus achieving fully automated mold transportation.

[0020] The mold opening and conveying assembly is used to convey the pipe pile mold after steaming to open the mold, and the cover mold and bottom mold after opening are respectively conveyed to workshop B and workshop C, so as to achieve the effect of cleaning and coating the cover mold and bottom mold in batches. The bottom mold in workshop C is first turned over and demolded, and then cleaned, so as to complete the efficient and automatic reuse of the mold.

[0021] The cover mold is cleaned and coated with a release agent through the longitudinal conveying device of the cover mold in workshop B after opening the cover, and finally transported to the top of workshop C for mold closing. In addition, a cage reinforcement conveying and unloading assembly is arranged above the middle part of workshop B, so that only one overhead crane is needed to automatically convey the cage reinforcement of the cage reinforcement production station far away from the production line, and automatically place it and move it to the top of workshop C for placement.

[0022] By using the bottom mold cleaning component, not only can the pile rods inside the bottom mold be flipped out of the mold, the bottom mold can be transported and cleaned, and the cage reinforcement and cover mold can be placed in sequence during transportation to complete the fully automated mold closing operation. The bottom mold can be cleaned and closed without manual operation, reducing labor costs and personnel risks.

[0023] The cage rebar conveying and unloading assembly is used to realize automated cage rebar unloading. The fixed cage rebar conveying and unloading assembly is positioned to enable the cage rebar crane to automatically load the cage rebar, thereby effectively reducing the difficulty and risk of operating the crane.

[0024] By setting up only four sets of cranes in three workshops, the automated pipe pile production effect can be achieved, and it can also meet the transportation of cage reinforcement and finished pile rods, greatly increasing the production efficiency of the pipe pile production line and reducing construction costs.

[0025] The fixed electric pile-pulling vehicle can realize the automatic positioning of the pile pole crane for lifting and transportation, reducing the lifting operation and personnel risks. It is also connected to workshop D through rails to efficiently transport and store the finished products. BRIEF DESCRIPTION OF THE DRAWINGS
