Description

Technical Field

[0001] The invention belongs to the field of building construction tools, and in particular relates to a SMW method pile construction device and a demoulding method thereof which are convenient for demoulding. Background Art

[0002] The basic principle of SMW pile construction is: insert profiles into traditional mixing piles to improve the stability of concrete. When the concrete solidifies to a certain extent, the profiles are pulled out so that the profiles can be reused. The cavities created by the profiles are filled with concrete. In the process of inserting profiles into mixing piles, the profiles cannot be inserted entirely by their own weight. The resistance of the profile insertion is affected by the concrete type, the weight of the profile itself, the bottom area, and the stones in the concrete. Therefore, downward pressure is required during the profile insertion process.

[0003] In the prior art, the profile is mainly pressed downward from the top by large machinery. Due to the long length of the profile, both the upper and lower ends of the profile are subjected to force during the pressing process, which can easily cause the profile to bend. Although the degree of bending is limited, any slight bending will lead to difficulty in demolding, and at the same time cause the profile to be scrapped and increase costs.

[0004] At present, demolding is generally carried out by a hydraulic demolding machine. The profile is first clamped by a clamp, and then the clamp and the profile are driven upward by a hydraulic cylinder. After the hydraulic cylinder is extended to the maximum length, the clamp is released, and the hydraulic cylinder drives the clamp to move downward, thus completing a cycle. Since the hydraulic cylinder cannot continuously move the profile upward, the process of hydraulic cylinder contraction leads to a waste of time. If the profile is to be completely pulled out, the hydraulic cylinder needs to contract several times, which significantly reduces the demolding efficiency. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a SMW pile construction device that is easy to demould, and designs a method for demoulding using the device, which is described in detail below.

[0006] To achieve the above object, the present invention is implemented through the following technical solutions: The invention discloses a SMW pile construction device which is convenient for demoulding, comprising a mobile base, two guide columns are vertically arranged on the mobile base, a mounting frame is arranged between the two guide columns, and two sides of the mounting frame are respectively slidably connected to the two guide columns; a limit stopper for limiting the upward sliding position of the mounting frame is fixedly connected to the upper end of the guide column; Two rotating shafts are rotatably arranged on the installation frame, each rotating shaft is connected to a roller, and a plurality of protrusions are formed on the surface of the roller; A mold is provided between the two rollers, and reduction motors are respectively provided on the outer side of the installation frame and at positions corresponding to the two rotating shafts, and the output shaft of the reduction motor is connected to the rotating shaft; The mold includes an H-shaped steel material, and a plurality of through holes are opened on both sides of the H-shaped steel material. When the roller rolls, the positions of the through holes correspond to the positions of the protrusions and can cooperate with each other. The two rollers rotate in opposite directions under the drive of the reduction motor, driving the mold to move up and down; a filling block is slidably matched in the through hole, and a fixed cover is connected to the inner side of the H-shaped steel material. A second spring is arranged between the filling block and the fixed cover; the second spring is connected to the filling block, and the filling block is pushed by the elastic force of the spring so that the filling block is flush with the surface of the H-shaped steel material in the through hole; The mobile base is also provided with two knocking components, which are connected to the rotating shaft and are used for continuously knocking the top of the installation frame.

[0007] The SMW pile construction device that is easy to demould is used, the mold is placed between two rollers, and the two rollers are driven to rotate in opposite directions by two reduction motors and two rotating shafts. The two rollers drive the mold downward through the protrusions and through the through holes, and the mold is inserted into the cement soil pile; after the protrusion enters the through hole, the filling block is squeezed and contracted by the protrusion, and after the protrusion is separated from the current through hole, the filling block will be reset under the push of the second spring, thereby ensuring the smoothness of the mold surface, thereby preventing cement from entering the mold through the through hole, and also preventing cement from filling the through hole and affecting demoulding; During the downward movement of the mold, the rotating shaft also drives the knocking assembly, so that the knocking assembly continuously knocks the installation frame. Under the action of the knocking assembly, the installation frame can be driven to move downward. The installation frame can further increase the downward power of the mold through the cooperation of the roller, the protrusion and the through hole. After the installation frame moves downward, it will move upward under the action of two rollers until it moves to the highest position. This design is to prevent the installation frame from moving downward continuously and finally contacting the moving base without downward space. However, in fact, after the installation frame moves downward, it can still move upward, but the mold cannot move upward with it, thereby achieving unilateral downward pressing of the mold. After the mold is completely pressed into the cement soil, the mold needs to be pulled out after the cement soil solidifies to a certain extent. At that time, the reduction motor needs to rotate the shaft in another direction, and the mold can be pulled out again through the cooperation of the roller, the protrusion and the through hole.

[0008] Preferably, four fixed covers are provided, and the four fixed covers are distributed on four corresponding inner surfaces of the H-shaped steel, and the top and bottom of the H-shaped steel with the four fixed covers installed are still H-shaped.

[0016] The present application also provides a demoulding method for a SMW pile construction device that is easy to demould, comprising the following steps: S1: Place the mold between two rollers, and use two reduction motors to drive two rotating shafts at the same time, so that the two rollers rotate in opposite directions. The rollers can drive the mold to move downward through the convex blocks and through the through holes, and insert the mold into the cement soil pile; S2: During the downward movement of the mold, the rotating shaft drives the knocking assembly to continuously knock the installation frame. Under the action of the knocking assembly, the installation frame is driven to move downward. The installation frame can further increase the downward power of the mold through the cooperation of the roller, the convex block and the through hole, and the mold is gradually inserted into the cement soil mixing pile. S3: After the mold is completely pressed into the cement soil, wait for the cement soil to solidify to a certain extent, and then pull out the mold. At this time, the reduction motor drives the shaft to rotate in the opposite direction, and the mold is pulled out again through the cooperation of the roller, the protrusion and the through hole.

[0017] The beneficial effects are: 1. The present invention drives two rollers to rotate in opposite directions through two reduction motors and two rotating shafts.

[0022] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0023] See also Figure 1-Figure 7 As shown, the present invention provides an SMW method pile construction device that is easy to demold, including a mobile base 1, two guide columns 2 are vertically arranged on the mobile base 1, and a mounting frame 3 is arranged between the two guide columns 2, and the two sides of the mounting frame 3 are respectively slidably connected to the two guide columns 2; the upper ends of the guide columns 2 are fixedly connected with limit blocks 33 for limiting the upward sliding of the mounting frame 3; two rotating shafts 5 are rotatably arranged on the mounting frame 3, each rotating shaft 5 is connected to a roller 6, and a plurality of protrusions 7 are formed on the surface of the roller 6, and a mold 11 is arranged between the two rollers 6, and reduction motors 4 are respectively arranged at positions corresponding to the two rotating shafts 5 on the outer side of the mounting frame 3, and the output shaft of the reduction motor 4 is connected to the rotating shaft 5; the protrusion 7 is an arc block matched with the through hole 27, and when the roller 6 rolls, at least two protrusions 7 match with the through hole 27, which can ensure the stable up and down movement of the mold 11.

[0024] refer to Figure 7As shown, the mold 11 includes an H-shaped steel 26, and a plurality of through holes 27 are provided on both sides of the H-shaped steel 26. When the roller 6 rolls, the positions of these through holes 27 correspond to the positions of the protrusions 7 and can cooperate with each other. The two rollers 6 rotate in opposite directions driven by the reduction motor 4, driving the mold 11 to move up and down; a filling block 28 is slidably fitted in the through hole 27, and a fixed cover 30 is connected to the inner side of the H-shaped steel 26, and a second spring 29 is provided between the filling block 28 and the fixed cover 30; the second spring 29 is connected to the filling block 28, and the filling block 28 is pushed by the elastic force of the spring, so that the filling block 28 is flush with the surface of the H-shaped steel 26 in the through hole 27. The filling block 28 is used to block the through hole 27, and the cooperation of the second spring 29 and the filling block 28 can continuously block the filling block 28, thereby preventing the mud in the mixing pile from entering the through hole 27; The movable base 1 is also provided with two knocking assemblies 8, which are connected to the rotating shaft 5 and are used to continuously knock the top of the installation frame 3. The two knocking assemblies 8 are driven by the two rotating shafts 5 respectively, and can continuously knock the top of the installation frame 3. The knocking assemblies 8 are used to generate continuous downward pressure on the mold 11, so that the mold 11 moves downward more smoothly. In the prior art, by pressing the top of the mold 11, the mold is easily pressed and deformed, and it is not easy to demold. In this application, the force-bearing position of the mold 11 is on both sides and in the middle position, so that the two ends of the mold 11 can be prevented from bending due to force.

[0025] The SMW pile construction device that is easy to demould is used, and the mold 11 is placed between the two rollers 6. The two reduction motors 4 cooperate with the two rotating shafts 5 to drive the two rollers 6 to rotate in opposite directions. The two rollers 6 cooperate with the protrusions 7 and the through holes 27 to drive the mold 11 to move downward, and the mold 11 is inserted into the cement soil pile; after the protrusion 7 enters the through hole 27, the filling block 28 is squeezed and contracted by the protrusion 7. After the protrusion 7 is separated from the current through hole 27, the filling block 28 will be reset under the push of the spring 29, thereby ensuring that the surface of the mold 11 is smooth, thereby preventing cement from entering the mold 11 through the through hole 27, and also preventing cement from filling the through hole 27 and affecting demoulding; During the downward movement of the mold 11, the rotating shaft 5 also drives the knocking assembly 8, so that the knocking assembly 8 continuously knocks the installation frame 3. Under the action of the knocking assembly 8, the installation frame 3 can be driven to move downward. The installation frame 3 can further increase the downward power of the mold 11 through the cooperation of the roller 6, the protrusion 7 and the through hole 27. After the installation frame 3 moves downward, it will move upward under the action of the two rollers 6 until the installation frame 3 moves to the highest position. This design is to prevent the installation frame 3 from moving continuously downward and finally contacting the movable base 1 without any downward space. However, in fact, after the installation frame 3 moves downward, it can still move upward, but the mold 11 cannot move upward with it, thereby achieving unilateral downward pressing of the mold 11.

[0026] After the mold 11 is completely pressed into the cement soil, the mold 11 needs to be pulled out after the cement soil solidifies to a certain extent. At this time, the reduction motor 4 needs to rotate the shaft 5 in another direction, and the mold 11 can be pulled out again through the cooperation of the roller 6, the protrusion 7 and the through hole 27.

[0028] Furthermore, the top and bottom of the H-shaped steel 26 are respectively connected with an upper mounting plate 31 and a lower mounting plate 32, and the upper mounting plate 31 and the lower mounting plate 32 are connected with the top and bottom of the four fixing covers 30 by screws; The bottom of the lower mounting plate 32 is a guiding blade surface, the two ends of the spring 29 are fixedly connected to the filling block 28 and the fixing cover 30 respectively, and the spring 29 is in the fixing cover 30, and the upper mounting plate 31 and the lower mounting plate 32 are flush with the top and bottom of the H-shaped steel 26 with four fixing covers 30 installed. The fixing cover 30 is provided to protect the spring 29 and prevent the spring 29 from being wrapped by cement and unable to expand and contract. In addition, the fixing cover 30 can make the H-shaped steel 26 more regular, thereby facilitating demoulding.

[0029] Preferably, a guide sleeve 12 is slidably connected to the mounting frame 3, the surface of the mold 11 is slidably matched with the inner wall of the guide sleeve 12, and an oil hopper 13 is provided on the upper side of the guide sleeve 12, and lubricating oil is filled in the oil hopper 13. The guide sleeve 12 is used to guide the mold 11 to keep it moving vertically. During the movement of the mold 11, its surface is stained with lubricating oil to facilitate subsequent demoulding. The lubricating oil can be replaced by other compliant anti-friction materials.

[0031] Specifically, refer to Figure 4As shown, the knocking assembly 8 includes a half gear 14 and a guide rod 18. The half gear 14 is connected to the end of the rotating shaft 5 away from the reducer. The guide rod 18 is vertically connected to the mobile base 1. A connecting plate 16 is slidably provided on the guide rod 18. A vertically provided rack 15 is fixedly connected to the side of the connecting plate 16, and the rack 15 is meshed with the half gear 14. A rectangular sleeve 21 is fixedly connected to the top of the rack 15. A movable plate 22 is slidably provided in the rectangular sleeve 21, and the movable plate 22 corresponds to the top of the installation frame 3. A counterweight 25 is installed on the rectangular sleeve 21. The rotating shaft 5 drives the half gear 14 to rotate, and the half gear 14 drives the rack 15 to move upward. When the half gear 14 is separated from the rack 15, the movable plate 22 will hit the upper side of the installation frame 3 under the action of gravity, providing downward power for the installation frame 3.

[0032] Preferably, the side of the rectangular sleeve 21 is connected with a bolt 23, and the bolt 23 passes through the rectangular sleeve 21 and is connected to the movable plate 22, and a rubber pad 24 is provided at the bottom of the movable plate 22. The rubber pad 24 can reduce the noise of the movable plate 22 hitting the installation frame 3; when the knocking component 8 is not needed to knock the top of the installation frame 3, the movable plate 22 is moved to be misaligned with the top of the installation frame 3, and the bolt 23 is rotated so that the bolt 23 supports the movable plate 22.

[0033] Preferably, a fixed arm 17 is fixedly mounted on the mobile base 1, and the fixed arm 17 is fixedly connected to the upper end of the guide rod 18, and a tension spring 19 and a spring 1 20 are sleeved on the guide rod 18; the guide rod 18 is a square rod. The tension spring 19 is located below the spring 1 20, and the two ends of the tension spring 19 are respectively fixedly connected to the mobile base 1 and the connecting plate 16, and the two ends of the spring 1 20 are respectively fixedly connected to the fixed arm 17 and the connecting plate 16. The connecting plate 16 is driven to move upward by the rack 15, and then the tension spring 19 is stretched and the spring 1 20 is compressed. When the tension spring 19 and the spring 1 20 rebound, the impact force of the movable plate 22 on the top of the installation frame 3 can be further increased.

[0034] The present application also provides a demoulding method for a SMW pile construction device that is easy to demould, comprising the following steps: S1: Place the mold 11 between the two rollers 6, and drive the two rotating shafts 5 through the two reduction motors 4 at the same time, so as to drive the two rollers 6 to rotate in opposite directions. The rollers 6 can drive the mold 11 to move downward through the protrusions 7 and the through holes 27, and insert the mold 11 into the cement soil pile; the filling block 28 cooperates with the spring 29 to ensure that the surface of the mold 11 is smooth, thereby preventing cement from entering the mold 11 through the through holes 27, and also preventing cement from filling the through holes 27 and affecting demolding; S2: During the downward movement of the mold 11, the rotating shaft 5 drives the knocking assembly 8, so that the knocking assembly 8 continuously knocks the installation frame 3. Under the action of the knocking assembly 8, the installation frame 3 is driven to move downward. The installation frame 3 can further increase the downward power of the mold 11 through the cooperation of the roller 6, the protrusion 7 and the through hole 27, and the mold 11 is gradually inserted into the cement soil mixing pile; S3: After the mold 11 is completely pressed into the cement soil, the mold 11 is pulled out after the cement soil solidifies to a certain extent. At this time, the reduction motor 4 drives the rotating shaft 5 to rotate in the opposite direction, and the mold 11 is pulled out again through the cooperation of the roller 6, the protrusion 7 and the through hole 27.

[0035] In the above method, two reduction motors 4 cooperate with two rotating shafts 5 to drive two rollers 6 to rotate in opposite directions. The two rollers 6 can drive the mold 11 to move downward through the protrusion 7 and the through hole 27. The reduction motor 4 rotates the rotating shaft 5 in another direction to pull out the mold 11, thereby significantly improving the efficiency of inserting and removing the mold 11. The rotating shaft 5 cooperates with the knocking component 8, so that the knocking component 8 continuously knocks the installation frame 3. Under the action of the knocking component 8, the installation frame 3 can be driven to move downward. The installation frame 3 can further increase the downward power of the mold 11 through the mutual cooperation of the rollers 6, the protrusion 7 and the through hole 27, thereby increasing the downward speed of the mold 11, which not only provides sufficient downward pressure on the mold 11, but also avoids the mold 11 from bending due to uneven force during the insertion process, resulting in the scrapping of the mold 11.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
