Description
Technical Field
[0001] This application relates to the field of pipe pile manufacturing technology, and in particular to a quantitative concrete pipe pile raw material feeding device. Background Technology
[0002] Concrete pipe piles are widely used in the construction of cities, roads, bridges, and seaports. As concrete pipe piles are large-scale products, their production involves processes such as batching, mixing, distributing, feeding, mold assembly, tensioning, centrifugation, ambient temperature curing, release and demolding, and high-pressure steam curing. Therefore, the factory area for concrete pipe pile production lines is generally quite large.
[0003] Chinese utility model patent application number CN2012207504674 discloses a novel pipe pile production line, including a feeding area, a concrete mixer and a material distribution vehicle in the feeding area, a mold-closing area behind the feeding area, a crane between the feeding area and the mold-closing area to move the pipe mold to the mold-closing area, a tensioning area behind the mold-closing area, a tensioning machine in the tensioning area, a centrifuge area behind the tensioning area, a centrifuge in the centrifuge area, a normal temperature steam curing area behind the centrifuge area, a steam curing tank in the normal temperature steam curing area, a demolding area behind the normal temperature steam curing area, a tension release machine for removing nuts on the pipe mold in the demolding area, a cage weaving area behind the demolding area, and upper mold conveyor chains and lower mold conveyor chains for conveying the pipe mold on one side or in the middle of the demolding area, the normal temperature steam curing area, the centrifuge area, and the mold-closing area, respectively. A crane is located between the cage weaving area and the demolding area, and a high-pressure steam curing area is located behind the cage weaving area.
[0004] Regarding the aforementioned technologies, in a pipe pile production line, the various functional components are often idle for a considerable period between the completion of one operation and the start of the next. Furthermore, during feeding, when concrete accumulates on the pipe pile mold, operators need to replenish or distribute the material, which affects production efficiency and easily leads to concrete waste. Summary of the Invention
[0005] To facilitate quantitative feeding of concrete pipe piles and reduce concrete waste, this application provides a quantitative concrete pipe pile raw material feeding device.
[0006] The quantitative concrete pipe pile raw material feeding device provided in this application adopts the following technical solution:
[0007] A quantitative concrete pipe pile raw material feeding device includes a placement component, a feeding component, and a receiving component. The placement component includes a placement platform and multiple support columns symmetrically arranged on both sides of the placement platform, with each group of support columns spaced apart. The support columns support the pipe pile mold. The feeding component is located above the placement platform and includes a feeding hopper, a guide component, and a support. The support is located above the placement platform, and the feeding hopper is slidably connected to the support. The sliding direction of the feeding hopper is the same as the long side direction of the placement platform, and the discharge port of the feeding hopper faces the pipe pile mold. The guide component is located at the discharge port of the feeding hopper and is used to scrape off excess concrete material on the pipe pile mold. The receiving component is located above the placement platform and is used to receive the concrete material scraped off the pipe pile mold. The receiving component is equipped with a weighing component, and the feeding hopper is equipped with a controller. The controller is electrically connected to the weighing component, which weighs the concrete material in the receiving component and sends the weight back to the controller. The controller is used to adjust the discharge amount from the feeding hopper.
[0008] By adopting the above technical solution, when producing concrete pipe piles, the pipe pile mold is placed on the support column, and the pipe pile mold is fed with a feeding hopper. The guide component scrapes the concrete on the pipe pile mold, and the scraped concrete falls onto the receiving component. The weighing component in the receiving component weighs the fallen concrete and feeds the weighing information back to the controller. The controller controls the feeding amount of the feeding hopper to adjust and replenish the concrete on the pipe pile mold. The concrete that falls onto the receiving component is finally recycled, which facilitates quantitative replenishment of the pipe piles and reduces concrete waste.
[0009] Optionally, the guide component includes a guide ring and a guide plate. The guide ring is detachably connected to the feeding hopper. The concave surface of the guide ring faces the placement platform. The guide ring can scrape off excess concrete material on the pipe pile mold. At least two guide plates are provided. At least two guide plates are symmetrically arranged on the feeding hopper. The guide plates are detachably connected to one side of the feeding hopper. The guide plates are used to block the concrete material at the end face of the pipe pile mold.
[0010] By adopting the above technical solution, when the feeding hopper moves along the support, the feeding hopper drives the guide ring to move above the pipe pile mold. The guide ring scrapes away the excess concrete above the pipe pile mold and levels the concrete above the pipe pile mold, thereby improving feeding efficiency. The guide plate reduces the possibility of concrete falling from the end face of the pipe pile mold during feeding.
[0011] Optionally, the receiving assembly includes a receiving plate, multiple guide columns, and multiple elastic elements. The placement platform has a receiving groove along its axis. Two receiving plates are symmetrically arranged along the receiving groove, with an included angle between the two receiving plates. The receiving plates are slidably connected to the support column along the high side of the support. The multiple guide columns and multiple elastic elements are all located below the receiving plate. One end of the guide column is connected to the receiving plate, and the other end is connected to the placement platform. The guide column is a telescopic column, and the elastic element is sleeved on the outside of the guide column with the compression direction being the same as the telescopic direction of the guide column.
[0012] By adopting the above technical solution, after the concrete falls onto the receiving plate, the receiving plate vibrates. Since the receiving plate is tilted, the concrete gathered on the receiving plate will fall into the receiving trough under vibration. The guide column and elastic element provide elastic support to the receiving plate, which facilitates the concrete to fall off the receiving plate.
[0013] Optionally, each of the receiving plates is equipped with a vibrating element, which is used to vibrate the receiving plate.
[0014] By adopting the above technical solution, the vibrating component vibrates the receiving plate, which facilitates the concrete on the receiving plate falling into the receiving trough.
[0015] Optionally, a movable component is provided below the placement platform, which is used to drive the placement platform to move forward or backward along its axial direction.
[0016] By adopting the above technical solution, the moving part can drive the placement platform to move in the same direction as the feeding hopper, and can cooperate with the feeding hopper to feed material into the pipe pile mold, thereby improving feeding efficiency.
[0017] Optionally, multiple rotating supports are provided on both sides of the placement platform, with the multiple rotating supports spaced apart. Each rotating support includes a fixed plate, a support column, and a receiving wheel. The fixed plate is connected to the placement platform, and the support column is slidably connected to the fixed plate. The support column is provided with a locking device, which is used to fix the position of the support column on the fixed plate. The receiving wheel is rotatably connected to the support column, and the peripheral sidewall of the receiving wheel abuts against the pipe pile mold.
[0018] By adopting the above technical solution, after the pipe pile mold is fed, the placement platform is moved to an area away from the feeding hopper using a moving part, the support column is brought closer to the pipe pile mold, and the support column is fixed by the locking part. After the receiving wheel abuts against the engaged pipe pile mold, the pipe pile mold is rotated, so that the concrete forms a hollow pipe pile under centrifugal force. There is no need to use a crane to move the pipe pile after feeding to the centrifugal zone, thus improving production efficiency.
[0019] Optionally, a camera is provided on the feeding hopper near the guide plate. The camera is electrically connected to the controller, which can adjust the discharge speed of the feeding hopper according to the shooting status of the camera.
[0020] By adopting the above technical solution, the camera can monitor the feeding of concrete on the pipe pile mold, so as to promptly feed the feeding status back to the controller, which facilitates the adjustment of the discharge speed of the feeding hopper and reduces the possibility of excessive feeding causing concrete to fall.
[0021] Optionally, the receiving trough is provided with a receiving box, the weighing component is located in the receiving box, and a baffle is rotatably connected to one end of the receiving box, the baffle being used to block one end of the receiving box.
[0022] By adopting the above technical solution, the concrete falls into the receiving box, the weighing device weighs the concrete and feeds the weight back to the controller, the controller controls the feeding hopper to drop the corresponding weight of concrete, so as to quantitatively measure the concrete in the pipe pile mold, and the baffle is rotated and connected to one end of the receiving box to facilitate cleaning the concrete in the receiving box.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By setting up a placement component, a feeding component, and a receiving component, the pipe pile mold is placed on the placement component for feeding. The feeding component can quantitatively discharge material into the pipe pile mold. The feeding component is equipped with a controller, which is electrically connected to the weighing device in the receiving component. When the weighing device weighs the falling concrete, it transmits the weight signal to the controller. After receiving the signal, the controller controls the control valve on the feeding hopper to discharge the corresponding weight, thereby facilitating quantitative replenishment of the pipe pile and reducing concrete waste.
[0025] 2. By installing cameras, the feeding status of the pipe pile mold can be monitored in real time;
[0026] 3. By setting rotating supports on both sides of the placement platform, the rotating supports can support the pipe pile mold after the feeding is completed, which facilitates the rotation of the pipe pile mold after feeding and locking. Attached Figure Description
