Description

Technical Field

[0001] The invention relates to the technical field of concrete pipe pile forming, in particular to a concrete pipe pile forming device. Background Art

[0002] Piles are a common form of foundation support in engineering structures. They are mainly used to reinforce and support the foundations of buildings, bridges and other projects when the foundation is poor or needs to bear a large load. Existing pipe piles are mostly tubular structures made of steel pipes, concrete pipes or other materials. They are driven into the ground to transfer the load of the building to a deeper and more solid stratum to increase the bearing capacity and stability of the foundation. Piles are easily corroded by acidic and alkaline environments due to their long-term contact with soil and water. Concrete pipe piles have good corrosion resistance and are not easily corroded and damaged by the external environment. As a common building material, concrete has a relatively low manufacturing cost. Therefore, concrete pipe piles are more economical than other pipe piles.

[0003] Some technical solutions for concrete pipe pile forming have also appeared in the prior art. For example, a Chinese patent with announcement number CN216884552U discloses concrete pipe pile forming equipment, including: electric cylinders are embedded in the four corners of the upper end of the base, an arc cover is fixed between the power ends of the electric cylinders, an upper heating component is installed in the arc cover, and a lower heating component is installed on the upper end of the base and between the rotating shafts. The pipe pile mold is placed on the rotating wheel, so that when the pipe pile mold rotates, the steel ball of the arc plate is in close contact with the pipe pile mold, which can make the rotation of the pipe pile mold more stable, and the upper part of the pipe pile mold can be heated by the upper electric heating wire of the arc plate, and then the bottom of the pipe pile mold can be heated by the heating box under the pipe pile mold and the lower electric heating wire inside the heating box, so that when the concrete pipe pile is formed in winter, the situation that the concrete solidification time is long due to the cold weather is prevented, so as to solve the problem that the existing concrete pipe pile forming equipment lacks a heating structure, resulting in the concrete pipe pile being easily affected by the low temperature when the concrete pipe pile is formed in winter; however, the technical solution heats the pipe pile mold by heat radiation, so that the heating box and the upper electric heating wire do not contact the pipe pile mold, resulting in poor heating effect, and the situation that the concrete solidification time is long cannot be avoided;

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 to 9As shown, a concrete pipe pile forming equipment described in the present invention includes a body 1; two groups of support seats are fixedly installed inside the body 1; each group of the support seats includes two bases 11; a rotating wheel 111 is rotatably connected between the two bases 11; a driving motor 112 is fixedly installed on one side of the body 1; the driving motor 112 is used to drive the rotating wheel 111 to rotate; two cover plates 2 are arranged above the body 1; the cover plates 2 are arranged in an arc shape; the cover plates 2 are rotatably sealed and connected to the body 1; a sealing strip 12 is fixedly connected to the upper end of the body 1; the sealing strip 12 is made of fluororubber material; the sealing strip 12 is located between the two cover plates 2; hydraulic push rods 13 are arranged on both sides of the body 1; one end of the hydraulic push rod 13 is rotatably connected to the body 1, and the other end is hinged to the cover plate 2; an air inlet 14 connected to an external steam pipeline is opened on one side of the body 1; a solenoid valve 141 is installed in the air inlet 14.

[0030] As an embodiment of the present invention, the two cover plates 2 are provided with mutually connected grooves 21 and strip grooves 22 on their adjacent sides; the grooves 21 are located below the strip grooves 22; a sealing plate 211 is connected in a sliding seal in the grooves 21; the sealing plate 211 is connected to the bottom of the grooves 21 via a sealing spring 212; a push plate 221 is connected in a sliding seal in the strip grooves 22; the sealing plate 211 is made of PTFE material.

[0031] As an implementation mode of the present invention, the grooves 21 on the two cover plates 2 are staggered and distributed up and down; a clamping groove 23 facing the grooves 21 is formed on one side of the two cover plates 2 close to each other.

[0032] As an embodiment of the present invention, a drainage cavity 15 communicating with the outside is provided at the bottom of the body 1; a sealing plug 151 is slidably and sealingly connected in the drainage cavity 15;

[0033] During operation; since the prior art heats the pile mold by heat radiation, the heating box and the upper electric heating wire are not in contact with the pile mold, resulting in poor heating effect, and the heating box is exposed to the outside world. In the process of the rotating wheel 111 driving the pile mold, the pile mold will rotate and drive the surrounding air flow, so that the flowing air will take away the heat energy radiated by the heating box, resulting in temperature loss, affecting the heating uniformity and effect of the surface of the pile mold, and prolonging the solidification time of the concrete in the pile mold; and the heating box also needs to consume more energy to maintain the required heating temperature, thereby increasing the consumption of electric energy;

[0034] In this regard, the present invention sets a cover plate 2 to cooperate with the machine body 1, so that the cover plate 2 can seal the machine body 1 during the process of the two cover plates 2 being turned over and closed, and then controls the external steam pipe to transport steam into the sealed machine body 1, so as to achieve heating of the pipe pile mold placed in the machine body 1, thereby preventing the concrete from solidifying slowly due to too low a temperature in a cold environment; and compared with the heating method of a heating box, steam is used as a heat transfer medium, thereby directly contacting the pipe pile mold, and can quickly and effectively transfer heat energy to the pipe pile mold and the internal concrete, and the heating speed is fast, thereby effectively improving the efficiency of concrete filling and molding; and no electric energy is consumed during the heating process, thereby reducing energy consumption;

[0035] In the initial state, the cover plate 2 is in a closed state, and two groups of rotating wheels 111 are provided. The driving motor 112 is used to drive one group of rotating wheels 111 to rotate. When the user uses a crane and transports the pipe pile mold filled with concrete to the top of the machine body 1 through a clamping device connected to the crane, the hydraulic push rod 13 is controlled to contract, so that the hydraulic push rod 13 can pull the two cover plates 2 to move away from each other, so that the two cover plates 2 no longer block the upper end of the machine body 1, so that the machine body 1 is opened. At this time, the crane is controlled to put the pipe pile mold into the machine body 1, so that the pipe pile mold is placed above the two groups of rotating wheels 111. At this time, the pipe pile mold is in rotational contact with the two groups of rotating wheels 111, and then the hydraulic push rod 13 is controlled to push the cover plates 2 to move in a direction close to each other until the two cover plates 2 are in contact and the machine body 1 is closed. Then the solenoid valve 141 in the air inlet 14 is controlled to open, so that the external steam pipeline transports steam and passes The air inlet 14 enters the body 1, and at the same time, the driving motor 112 is controlled to drive the rotating wheel 111 to rotate, so that the rotating wheel 111 can drive the pipe pile mold in rolling contact with it to rotate, so that the concrete in the pipe pile mold adheres to the inner wall of the pipe pile mold under the action of centrifugal force; at this time, the steam entering the body 1 can heat the pipe pile mold, so that the concrete in the pipe pile mold becomes more fluid and easier to fill every corner of the pipe pile mold, which helps to reduce the generation of bubbles and improve the molding quality of the concrete pipe pile; and the hydration reaction rate of concrete usually increases with the increase of temperature, because the increase in temperature will promote the chemical reaction rate of the hydration reaction, thereby reducing the latent period of the hydration reaction; so that the concrete particles can start to form hydration products faster in a shorter time, thereby accelerating the early strength development of the concrete and also increasing the hardening speed of the concrete pipe pile; thereby accelerating the molding of the concrete pipe pile;

[0036] Since the cover plate 2 blocks the upper end of the machine body 1 by closing, a gap will be generated between the cover plate 2 and the machine body 1, and the steam entering the machine body 1 will carry heat and dissipate from the gap between the cover plate 2 and the machine body 1 and the gap between the two cover plates 2, thereby causing heat loss in the machine body 1. For this reason, it is necessary to continuously transport steam into the machine body 1 to ensure that the steam heat in the machine body 1 remains stable, which in turn leads to increased energy consumption and increased operating costs. Therefore, by arranging the sealing strip 12 and the sealing plate 211, before the two cover plates 2 come into contact, the cover plate 2 will come into contact with the sealing strip 12, so that the cover plate 2 squeezes the sealing strip 12 to deform, until the two cover plates 2 come into contact, at which time the sealing strip 12 fits tightly with the cover plate 2 under the action of the elastic restoring force, so that the sealing strip 12 is 12 can block the gap between the cover plate 2 and the body 1; and the sealing strip 12 is made of fluororubber material, so that the sealing strip 12 has the advantage of wear resistance and improves the service life of the sealing strip 12; and in the process of the two cover plates 2 approaching each other, the cover plate 2 will drive the push plate 221 to approach each other, so that the push plates 221 of the two cover plates 2 first contact, at this time, the two push plates 221 squeeze each other and enter the strip groove 22, so that the gas in the strip groove 22 enters the groove 21 connected to the strip groove 22 under the push of the push plate 221, so that the sealing plate 211 in the groove 21 stretches the sealing spring 212 out of the groove 21 under the push of the gas, until the sealing plate 211 extending out of the groove 21 contacts the corresponding cover plate 2, so that the sealing plate 211 is in the cover plate 2. The gas in the groove 21 is blocked and squeezed to enter the groove 21. At this time, the sealing plate 211 and the cover plate 2 are in sliding sealing contact until the two cover plates 2 are in contact. At this time, the groove 21 is directly opposite to the card slot 23, so that the sealing plate 211 in the groove 21 can enter the card slot 23 under the push of the restoring force of the sealing spring 212, so that the sealing plate 211 inserted into the card slot 23 can completely block the gap between the two cover plates 2; and by arranging the two grooves 21 to be distributed up and down, the sealing plates 211 in the groove 21 are distributed up and down, so that the two sealing plates 211 can double block the two cover plates 2, so as to improve the sealing effect of the cover plate 2 on the inside of the body 1; prevent steam from escaping, reduce the heat loss in the body 1, and then do not need to be continuously Steam is transported into the machine body 1, which reduces energy consumption and operating costs; and the sealing plate 211 is made of PTFE material, so that the sealing plate 211 made of PTFE material not only has a good heat insulation effect, reduces the heat loss of steam, but also has the advantage of a low friction coefficient, reduces the friction damage between the sealing plate 211 and the cover plate 2, and the PTFE material has good elasticity. When the two cover plates 2 are separated from each other, the sealing plate 211 located in the card slot 23 will bend, but after the sealing plate 211 extends out of the card slot 23, the bent sealing plate 211 will reset under the action of its own elastic restoring force, and then be pulled into the groove 21 by the sealing spring 212; the sealing plate 211 is prevented from being damaged due to bending, so that the practicality of the present invention is improved;

[0037] Before the steam is filled, the cover plate 2 and the machine body 1 are sealed. As the steam is filled, the air pressure in the machine body 1 will increase, that is, the air pressure around the pipe pile mold will increase. However, when the external air pressure increases to a certain range, it will affect the sealing performance of the pipe pile mold, thereby affecting the molding quality of the concrete inside the pipe pile mold. For this reason, by setting the drainage chamber 15, before the steam is filled, the sealing plug 151 of the drainage chamber 15 away from the air inlet 14 is removed. As the steam is continuously filled, the air in the machine body 1 will be discharged from the end of the drainage chamber 15 away from the air inlet 14 under the push of the steam until the steam is discharged from the drainage chamber 15. Due to the tiny water droplets or small water in the steam The beads are suspended in the air and scatter light, so they appear white; therefore, when the user observes thick white smoke being discharged from the drainage chamber 15, the steam filling in the body 1 has been completed at this time, and the solenoid valve 141 in the air inlet 14 is controlled to be closed. At the same time, the user uses a tool to remove the sealing plug 151 and reinsert it into the drainage chamber 15 to seal the inside of the body 1. When the steam is filled, the drainage chamber 15 is in an open state, that is, during the process of filling with steam, the pressure in the body 1 is stable, which avoids the increase of the pressure in the body 1, thereby preventing the pressure in the body 1 from being too high and affecting the sealing performance of the pipe pile mold, thereby improving the molding quality of the concrete pipe piles in the pipe pile mold.

[0038] As an embodiment of the present invention, an air cavity 24 communicating with the air inlet 14 is formed inside the cover plate 2 ; an air hole 25 communicating with the air cavity 24 is formed on a side of the cover plate 2 close to the rotating wheel 111 .

[0039] As an embodiment of the present invention, a circular groove 16 is provided at the bottom of the body 1; an air duct 161 is provided inside the body 1; one end of the air duct 161 is connected to the air inlet 14, and the other end is connected to the circular groove 16; two solenoid valves 141 are provided; one of the solenoid valves 141 is installed in the air inlet 14; the other solenoid valve 141 is installed in the air duct 161; a vane 162 is provided in the circular groove 16; the vane 162 is rotatably connected to the bottom of the circular groove 16 through a rotating shaft 163; the driving motor 112 is used to drive the vane 162 to rotate; the drainage chamber 15 is connected to the circular groove 16.

[0040] As an embodiment of the present invention, the output shaft of the driving motor 112 is fixedly connected to a bevel gear ring 113; a bevel gear shaft 17 meshing with the bevel gear ring 113 is arranged below the bevel gear ring 113; the bevel gear shaft 17 is rotatably installed at the bottom of the body 1; the bevel gear shaft 17 is connected to the rotating shaft 163 through a belt drive.

[0041] As an embodiment of the present invention, a mounting chamber 18 is provided below the drainage chamber 15; a transmission gear 181 is rotatably connected in the mounting chamber 18; two groups of transmission gears 181 are provided; the two groups of transmission gears 181 are connected by belt transmission through a transmission belt 19; one group of the transmission gears 181 is fixedly connected to the bevel gear shaft 17; the other group of the transmission gears 181 is fixedly connected to the rotating shaft 163; a tooth groove 191 is provided on the inner ring wall of the transmission belt 19; the transmission belt 19 is meshed with the transmission gear 181 through the tooth groove 191 of the inner ring wall;

[0042] During operation, in the process of steam delivery, steam enters from the air inlet 14 and is discharged from the end of the drainage chamber 15 away from the air inlet 14, so that the temperature of the steam near the air inlet 14 is higher; and as the steam moves away from the air inlet 14, the temperature continues to decrease. For this purpose, the present invention sets an air hole 25. In the initial state, the airway 161 and the electromagnetic valve 141 in the air inlet 14 are in a closed state. When steam needs to be introduced, the sealing plug 151 in the drainage chamber 15 is first removed, and then the electromagnetic valve 141 in the air inlet 14 is controlled to open, so that the steam enters the air cavity 24 through the air inlet 14, and then is ejected from the top to the bottom through the air hole 25 connected with the air cavity 24, so that the ejected steam can push the cavity in the body 1 into the drainage chamber 15 through the circular groove 16 until the steam After the air in the drainage chamber 15 is discharged, the sealing plug 151 is inserted into the drainage chamber 15, and the electromagnetic valve 141 controlling the air inlet 14 is closed at this time; since the air holes 25 are arranged in a row on the lower end surface of the cover plate 2, the steam ejected from the air holes 25 can be filled in the body 1 to ensure the stability of the lateral temperature in the body 1; since the hot steam rises, the temperature near the air holes 25 is higher; and the temperature away from the air holes 25 is lower, that is, the longitudinal temperature distribution of the body 1 is uneven, and the electromagnetic valve 141 in the air passage 161 is opened to control the rotation of the rotating wheel 111 by the driving motor 112, and the rotating wheel 111 can drive the pile mold to rotate; since the output shaft of the driving motor 112 is fixedly connected with the bevel gear ring 113, the driving motor 1 12 can drive the bevel gear ring 113 to rotate, so that the bevel gear ring 113 drives the bevel gear shaft 17 meshing with it to rotate synchronously. Since the bevel gear shaft 17 is connected to the rotating shaft 163 through a belt drive, the bevel gear shaft 17 can drive the rotating shaft 163 to rotate, so that the rotating shaft 163 drives the blade 162 connected to the circular groove 16 to rotate, so that the blade 162 can discharge the gas in the circular groove 16 during the rotation process. Since the circular groove 16 is connected to the air inlet 14 through the air channel 161, and the air hole 25 is connected to the air inlet 14 through the air cavity 24, when the electromagnetic valve 141 in the air inlet 14 is closed and the electromagnetic valve 141 in the air channel 161 is opened, the circular groove 16 and the air hole 25 are in a connected state, and at this time, the air hole 25 will discharge the gas in the circular groove 16. The steam from the upper side is sucked in and transported to the air channel 161 through the air cavity 24, so that the steam flows from the air channel 161 into the circular groove 16, and is finally blown to the bottom of the pipe pile mold by the blade 162, so that the steam can circulate in the machine body 1, thereby avoiding the steam from gathering at the air hole 25, and ensuring the stability of the temperature around the pipe pile mold; and by arranging the tooth groove 191 on the inner wall of the transmission gear 181 and the transmission belt 19 to cooperate, the transmission stability between the transmission gear 181 and the transmission belt 19 is improved, and the transmission belt 19 is prevented from becoming loose due to heat collision caused by temperature increase, thereby affecting the transmission effect between the bevel gear shaft 17 and the rotating shaft 163, ensuring that the bevel gear shaft 17 and the rotating shaft 163 can be stably transmitted, so as to ensure that the steam can circulate normally in the machine body 1;This ensures that the surface of the pile mold is heated uniformly, so that the concrete in the pile mold can also maintain a stable hydration reaction due to uniform heating, ensuring the consistency of the overall strength and quality of the concrete pile, and avoiding the problem of strength disparity or quality difference; finally, after the concrete pile in the pile mold is finalized, the user can choose to lift it out and transport it to the curing room for curing, or directly perform curing in the body 1 by controlling the content of steam introduced into the body 1 to change the temperature, humidity and other conditions in the body 1, thereby avoiding delaying the timely oxidation time of the concrete pile due to insufficient storage space in the curing room, and avoiding the concrete pile formed in the pile mold from lack of water and cracking due to failure to timely curing, thereby improving the quality of the concrete pile. ;
