Description
Technical Field
[0001] The present invention relates to the technical field of pipe pile mold clamping, and specifically to a rapid clamping device for the production of concrete pipe piles. Background Art
[0002] Currently, when producing concrete pipe piles, the processing is carried out in the following order: wire drawing, cage weaving, concrete material placement, mold clamping, tensioning, centrifugal forming, steam protection, and demolding.
[0003] Among them, after the operation of placing concrete material in the concrete pipe pile mold, the bolts on the pipe pile mold need to be tightened, and then the pipe pile mold is lifted by a ceiling crane and transported to the centrifugal forming device for centrifugal forming. However, for the current existing pipe pile mold clamping operation, at least two workers hold a screw tightening machine and stand on both sides of the pipe pile mold to tighten the bolts on the pipe pile mold one by one. This method has the following problems: 1. High labor intensity and low labor efficiency. Two workers need to hold a heavy screw tightening machine to align the bolt heads and tighten them one by one, which places a large physical burden on the workers. Moreover, because the pipe pile mold is relatively long and the connecting bolts required for mold clamping are relatively many, the entire mold clamping operation process takes a particularly long time. During mass production, it often seriously slows down the entire production progress, resulting in a decline in the production efficiency of the enterprise; 2. Poor processing quality of mold clamping and unsatisfactory mold clamping effect. As the mold clamping work continues, the mold clamping workers often fail to tighten properly or even miss tightening due to physical fatigue, resulting in the leakage or seepage of concrete from the pipe pile mold during subsequent centrifugal forming production operations, and even material splashing during centrifugation, leading to the failure of the release forming process, generating a large number of defective products, wasting a large amount of raw materials, increasing production costs, and the bolts that are not tightened or missed tightening are very likely to fall off and fly out during the high-speed rotation of centrifugal motion, which not only easily causes production accidents but also threatens the production safety of workers. Therefore, in view of the above problems, improvement is urgently needed. Summary of the Invention
[0004] The purpose of the present invention is to provide a rapid mold clamping device for the production of concrete pipe piles, which can rapidly perform the mold clamping operation on the pipe pile mold, rapidly tighten the bolts on the pipe pile mold, reduce the labor intensity of workers, improve the processing quality of mold clamping of the pipe pile mold, prevent the occurrence of improper tightening or missed tightening, reduce production costs, and improve the economic benefits of the enterprise.

A tightening motor is installed inside the housing. The output shaft end of the tightening motor extends out of the housing and is fixedly connected to an upper partition plate and a pipe sleeve through a second bolt. The pipe sleeve has a hollow structure and an activity rod is movably arranged inside. The lower end of the pipe sleeve is installed and provided with a lower partition plate through a third bolt. A first spring is arranged between the activity rod and the upper partition plate. The lower end of the activity rod passes through the lower partition plate and is fixedly provided with a tightening seat body. A polygonal groove is arranged inside the tightening seat body.
[0007] Further, a second spring is wound around the activity rod between the lower partition plate and the tightening seat body. Guide rods are annularly arranged at the upper end of the tightening seat body, and the guide rods pass upward through the lower partition plate.
[0008] Further, the polygonal groove is matched with the bolt head on the pipe pile mold. An anti-slip pad for increasing friction is arranged inside the polygonal groove. The anti-slip pad is a curved plate-shaped structure made of rubber material.
[0009] Further, the guiding device includes an upper fixing plate and a lower fixing plate. The upper fixing plate is fixed to the lower surface of the top plate by a fifth bolt and a second positioning pin. In the middle of the lower surface of the upper fixing plate, a guiding cylinder is fixedly arranged. A guiding column is movably arranged inside the guiding cylinder. The lower end of the guiding column is fixedly arranged on the upper surface of the lower fixing plate.

[0012] Further, limiting plate bodies are installed on the upper surface of the moving seat on both sides of the supporting boss by first bolts. The limiting plate bodies are in the structure of L-shaped plate bodies and are used for limiting when the pipe pile mold is placed. An arc-shaped groove is arranged inside the supporting boss, and the arc-shaped groove is matched with the running wheels of the pipe pile mold.
[0013] Further, a travel switch support frame is fixedly arranged on the upper surface of the left side of the base plate. A travel switch is installed on the travel switch support frame, and the left end side wall of the leftmost moving seat can press the pressing head of the travel switch.
[0014] The beneficial effects of the present invention: The present invention provides a quick mold closing device for the production of concrete pipe piles. It can quickly perform mold closing operations on the pipe pile mold, quickly tighten the bolts on the pipe pile mold, reduce the labor intensity of workers, improve the processing quality of the mold closing of the pipe pile mold, prevent the phenomenon of un-tightening or missed tightening, reduce production costs, and improve the economic benefits of the enterprise.
[0015] 1. In the present invention, a first motor, a first screw rod, a first screw rod nut, a moving seat and a linear guide rail are provided. When performing mold closing and tightening operations, first, the pipe pile mold to be mold closed is hoisted by a ceiling crane to the supporting boss of the moving seat. The first motor is driven. The output shaft end of the first motor drives the first screw rod to rotate. The first screw rod nut and the moving seat linearly transport the pile mold to the left. The linear guide rail and the rollers assist the moving seat to move to the left. When the leftmost moving seat presses the pressing head of the travel switch, the first motor stops rotating, so that the pipe pile mold enters below the top plate, providing preparation for the tightening device to tighten the bolts on the pipe pile mold.
[0016] 2. In the present invention, a second motor, a second screw rod, a second screw nut and a tightening device are provided. By driving the second motor, which is a servo motor, the second screw nut can be controlled to move horizontally in a straight line on the second screw rod, so that the tightening device moves to directly above the bolt of the pipe pile mold to the right. Then, by driving the hydraulic cylinder, the lifting plate descends. By driving the tightening motor, the bolt of the pipe pile mold is tightened. By providing the second motor, the second screw rod and the second screw nut, the existing mold closing method is replaced, and it is no longer necessary for two workers to tighten each bolt of the pipe pile mold one by one, reducing the labor intensity of the workers. Moreover, by inputting a pulse signal to the second motor to control the distance that the second screw nut moves to the right on the second screw rod, the tightening operation of the bolts of the pipe pile mold can be carried out sequentially, with high tightening efficiency, fast tightening speed, saving labor production costs and improving production efficiency at the same time, and ensuring the overall processing and production efficiency of the pipe pile production line.
[0017] 3. In the present invention, a slide bar and a sliding sleeve are provided on the sliding plate, which can provide a lateral guiding function during the horizontal linear movement of the sliding plate, enabling the sliding plate to move smoothly horizontally to the right, improving the overall stability and practicality of the device.
[0018] 4. In the present invention, the tightening device is provided with a first spring, a second spring, a tightening motor and a tightening seat body. When the lifting plate descends, the polygonal groove in the tightening seat body cooperates with the bolt head of the pipe pile mold. The first spring and the second spring are both in a compressed state. By driving the tightening motor, the output shaft end of the tightening motor drives the tightening seat body to rotate, tightening the bolt of the pipe pile mold. Along with the downward tightening of the bolt of the pipe pile mold, the first spring and the second spring release pressure downward, prompting the tightening seat body to squeeze the top of the bolt of the pipe pile mold, ensuring the continuous progress of the tightening operation and preventing the phenomenon of incomplete tightening at the same time. It completely solves the problem in the existing method that workers hold a screw tightening machine to tighten the bolts of the pipe pile mold one by one, and the bolts cannot be completely tightened or the tightening degree is inconsistent, greatly reducing the labor intensity of the workers, lightening the labor burden, and also preventing the un-tightened bolts from flying out during the centrifugal forming process of the pipe pile mold, causing production accidents.
