Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, in particular to a new type of cement pipe casting and forming equipment. Background Art

[0002] In the field of cement pipe manufacturing, traditional casting equipment and technology have always dominated. However, with the continuous advancement of technology and changes in market demand, traditional equipment and technology have gradually exposed some defects and cannot meet the current higher requirements for cement pipe quality and production efficiency. Most of the existing cement pipe casting and molding equipment adopts a relatively simple mold structure and casting process. The positioning of the steel cage and the control of the density of the concrete often rely on manual operation and experience judgment. This method is not only inefficient, but also difficult to ensure the precise position of the steel cage and the uniform density of the concrete. In particular, in terms of the positioning of the steel cage, due to the lack of precise adjustment and positioning mechanism, the position of the steel cage often deviates from the center, resulting in uneven stress distribution of the cement pipe when it is under pressure, reducing the bearing capacity and overall structural stability of the cement pipe; In addition, in terms of concrete density control, traditional equipment and technologies usually use manual tools such as vibrators for vibration. This method is not only cumbersome to operate, but also difficult to ensure the vibration effect. Uneven or insufficient vibration will cause bubbles and voids in the concrete, affecting the strength and durability of the cement pipe. Summary of the invention

[0008] As a further preferred embodiment of the present technical solution, positioning holes are provided on both sides of the positioning frame, and the specifications of the positioning holes are compatible with the specifications of the steel cage body.

[0009] As a further preferred embodiment of the present technical solution, a disc is rotatably connected to the inner end of the support seat, and the inner casting mold is installed on the disc. A positioning rod is rotatably connected to the top of the disc, and a spline groove that matches the spline rod is provided on the top of the drive motor.

[0010] As a further preferred embodiment of the present technical solution, arc-shaped frames are symmetrically arranged on both sides of the bottom of the support seat, the inner end of the arc-shaped frame is slidably connected to a sliding column, a connecting rod is fixedly connected to the inner side of the sliding column, the other end of the connecting rod is fixedly connected to the outer wall of the disc, a second damping spring is arranged on the inner wall of the arc-shaped frame, one end of the second damping spring is fixedly connected to the sliding column, and a traction rope is arranged on the side wall of the sliding column.

[0011] As a further preferred embodiment of the present technical solution, a winding roller is connected to the other end of the traction rope, and the winding roller is rotatably installed on the support seat, a winding and unwinding motor is arranged at one end of the winding roller, and a guide wheel for guiding the traction rope is fixedly connected to one end of the arc frame.

[0012] As a further preferred embodiment of the present technical solution, the casting outer mold includes two half molds rotatably mounted on a support seat, the two half molds are rotatably spliced ​​into the casting outer mold, the outer walls of the two half molds are provided with fixing clamps, and the two fixing clamps are provided with bolts.

This precise positioning is crucial to the load-bearing capacity and overall structural stability of the cement pipe.

[0014] The inner wall of the casting mold is periodically tapped with a tapping rod, generating high-frequency vibrations. This vibration significantly enhances the vibration effect inside the concrete, thereby fully compacting the concrete and effectively removing the bubbles therein, which is of great significance for improving the strength and durability of the cement pipe.

[0015] After the cement pipe solidifies to a certain degree, the rotation of the casting inner mold is realized through the cooperation of the reeling and winding motor and the traction rope, and the inner wall of the cement pipe is smoothed. This method not only avoids damage to the cement pipe during the demolding process, but also prevents the inner wall of the cement pipe from collapsing or becoming uneven, thereby ensuring the integrity and smoothness of the inner wall of the cement pipe.

[0016] Through the coordination of motors and mechanical devices, multiple steps such as positioning of steel cages, pouring and vibration compaction of concrete, and smoothing of the inner wall of cement pipes are automated. This not only improves production efficiency, but also reduces the difficulty and labor intensity of manual operation. The above-mentioned processes and technologies not only ensure the center positioning and internal density of the cement pipe, but also avoid damage and collapse of the cement pipe by optimizing the demoulding process. These measures jointly ensure the overall quality and long-term stability of the cement pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: a new cement pipe casting and forming device, comprising a support seat 1 and a steel cage body 4, a casting inner mold 2 and a casting outer mold 3 are arranged on the top of the support seat 1, and the steel cage body 4 is placed between the casting inner mold 2 and the casting outer mold 3. In order to ensure the stability of the device and the convenience of operation, a control component 5 is also arranged on the support seat 1; The control assembly 5 includes a fixed plate 51 fixedly mounted on the support seat 1, the fixed plate 51 is slidably connected to a lifting frame 52 in the vertical direction, one end of the lifting frame 52 is fixedly connected to a positioning frame 53, the bottom end of the positioning frame 53 is fixedly connected to a fixing ring 54, and the bottom end of the fixing ring 54 is fixedly connected to a connecting plate 55. In order to effectively knock and vibrate the inner wall of the casting inner mold 2, knocking rods 511 are provided on the fixing ring 54 and the connecting plate 55; In order to achieve precise control of the knocking rod 511, a driving motor 56 is fixedly installed on the top of the positioning frame 53, and a spline rod 58 is fixedly connected to the output end of the driving motor 56. The spline rod 58 is rotatably mounted on the connecting plate 55, and a cam 59 is fixedly connected to the outer wall of the spline rod 58. By turning on the driving motor 56, the spline rod 58 and the cam 59 can be driven to rotate synchronously; In order to ensure the stability and accuracy of the knocking rod 511, positioning blocks 510 are fixedly installed around the top of the connecting plate 55, and the knocking rod 511 is slidably installed on the fixing ring 54 and the positioning block 510. The inner end of the knocking rod 511 slides in contact with the outer wall of the cam 59, and the outer wall of the knocking rod 511 is fixedly connected to a limiting block 527. The limiting block 527 is located at the outer end of the positioning block 510. A first damping spring 512 is provided between the limiting block 527 and the fixing ring 54. When the cam 59 rotates to the concave surface during continuous rotation, the first damping spring 512 is pressed against the outer wall of the knocking rod 511. Under the elastic force of 512, the limit block 527 and the knocking rod 511 are pushed to move inward. When the cam 59 rotates to the convex surface, the knocking rod 511 can be pushed to move outward and compress the first damping spring 512. In this way, the knocking rod 511 can knock the inner wall of the casting inner mold 2. Through this reciprocating motion, the knocking rods 511 at different positions can continuously knock different positions of the inner wall of the casting inner mold 2. This high-frequency vibration acts on the concrete, which can significantly improve the vibration effect inside the concrete, thereby fully compacting it and removing bubbles, thereby ensuring the quality of the concrete. An adjusting motor 513 is installed on the top of the fixing plate 51, and its output end is fixedly connected to the screw rod 514. The screw rod 514 is tightly connected to the lifting frame 52 through threads, ensuring that the lifting frame 52 can move up and down accurately along the screw rod 514. In addition, sliding rods 515 are fixedly connected to both sides of the fixing plate 51, and the lifting frame 52 is slidably installed on the sliding rods 515. The adjusting motor 513 can drive the screw rod 514 to rotate forward or reverse through its power output. When the adjusting motor 513 is started, it will drive the screw rod 514 to rotate synchronously, and then through the threaded connection between the screw rod 514 and the lifting frame 52, the lifting frame 52 can be moved up and down. The function of the sliding rod 515 is to assist the lifting frame 52 to move smoothly and accurately in the vertical direction, ensuring the smoothness of the lifting process and the accuracy of positioning; Positioning holes 57 are designed on both sides of the positioning frame 53. The specifications of these positioning holes 57 are completely compatible with the size of the steel cage body 4. When the lifting frame 52 drives the positioning frame 53 to move downward, the positioning holes 57 on the positioning frame 53 will be accurately engaged with the steel bars of the steel cage body 4. This design enables the steel cage body 4 to be accurately positioned to ensure that it is centered. The steel cage body 4 is positioned between the casting inner mold 2 and the casting outer mold 3. This can effectively avoid unnecessary movement of the steel cage during the casting process and prevent its position from deviating from the center. If the position of the steel cage is offset, the cement pipe may have uneven stress distribution when subjected to force, resulting in some parts being subjected to excessive pressure, while other parts may be subjected to less pressure. This uneven stress distribution will reduce the overall bearing capacity of the cement pipe. In addition, the offset of the steel cage may also cause gaps or cracks to appear inside the cement pipe. These gaps or cracks will become channels for the penetration of moisture and corrosive substances, thereby accelerating the aging and damage of the cement pipe. Especially in a humid or corrosive environment, this effect will be more significant, posing a threat to the long-term durability and safety of the cement pipe. The inner side end of the support seat 1 is rotatably connected to a disc 526, and the casting inner mold 2 is installed on the disc 526. The top of the disc 526 is rotatably connected to a positioning rod 516 to ensure that it can be accurately positioned. The top of the driving motor 56 is provided with a spline groove 517 that is compatible with the spline rod 58. When the lifting frame 52, the positioning frame 53, the fixing ring 54, the connecting plate 55 and the spline rod 58 move downward together, the spline rod 58 will be engaged in the spline groove 517 of the positioning rod 516. This process ensures that the positions of the lifting frame 52, the positioning frame 53, the fixing ring 54, the connecting plate 55 and the spline rod 58 can be accurately positioned and fixed, thereby ensuring the stability of the entire device and the accuracy of operation; Arc-shaped frames 518 are symmetrically arranged on both sides of the bottom of the support seat 1. The inner ends of the arc-shaped frames 518 are slidably connected to the sliding column 519. The inner side of the sliding column 519 is fixedly connected to the connecting rod 520. The other end of the connecting rod 520 is firmly fixed to the outer wall of the disc 526. A second damping spring 521 is arranged on the inner wall of the arc-shaped frame 518, one end of which is fixedly connected to the sliding column 519. A traction rope 522 is arranged on the side wall of the sliding column 519. The other end of the traction rope 522 is connected to the winding roller 524, which is designed to be rotatably mounted on the support seat 1, and one end of the winding roller 524 is also equipped with a winding and unwinding motor 525. In addition, one end of the arc frame 518 is fixedly connected to a guide wheel 523, and the function of the guide wheel 523 is to effectively guide the traction rope 522. When the steel cage body 4 is placed inside the casting inner mold 2 and the casting outer mold 3, cement pouring is then carried out to form a cement pipe. When the cement pipe is solidified to a certain extent, the two reeling and winding motors 525 are started to drive the reeling roller 524 to rotate synchronously. The reeling roller 524 will reel the traction rope 522 during the rotation, and the guide wheel 523 is responsible for transmitting the reeling and winding of the traction rope 522. When the reeling roller 524 reels the traction rope 522, the traction rope 522 will pull the sliding column 519 and the connecting rod 520 to slide on the arc frame 518 and compress the second damping spring 521. As a result of this series of actions, the connecting rod 520 drives the casting inner mold 2 to rotate. While the casting inner mold 2 rotates, it will smooth the inner wall of the cement pipe through its outer wall. In this way, when the casting inner mold 2 is no longer in close contact with the cement pipe, it can ensure that the casting outer mold 3 will not damage the cement pipe during the separation process from the cement pipe, thereby avoiding the collapse of the cement pipe. This design can better ensure the integrity of the outer wall of the cement pipe and ensure the quality and efficiency of the entire production process.

[0021] In the embodiment of the present invention, the steel cage body 4 is placed between the inner casting mold 2 and the outer casting mold 3, and the screw rod 514 is synchronously rotated by starting the adjustment motor 513, thereby driving the threaded lifting frame 52 to move downward. As the lifting frame 52 descends, the positioning frame 53, the fixing ring 54, the connecting plate 55 and the spline rod 58 also move downward accordingly. When the engaging part of the spline rod 58 is precisely matched with the spline groove 517 on the positioning rod 516, the positions of the lifting frame 52, the positioning frame 53, the fixing ring 54, the connecting plate 55 and the spline rod 58 are accurately fixed; In the process of accurately aligning the positioning holes 57 on the positioning frame 53 with the steel bars on the steel cage body 4, the position of the steel cage body 4 is centered to ensure that the steel cage body 4 is located at the center of the casting inner mold 2 and the casting outer mold 3, which can prevent the steel cage from moving during the casting process, thereby avoiding the steel cage from deviating from the center. If the steel cage is not in the right position, the cement pipe may experience uneven stress distribution when it is under pressure, causing some parts to be under excessive pressure, while other parts may be under less pressure. This uneven stress distribution will reduce the overall load-bearing capacity of the cement pipe. In addition, the deviation of the steel cage may also cause gaps or cracks to appear inside the cement pipe. These gaps or cracks will become channels for the penetration of moisture and corrosive substances, accelerating the aging and damage of the cement pipe, especially in a humid or corrosive environment, this effect will be more significant; After the positioning of the steel cage body 4 is completed, cement pouring is then carried out to form a cement pipe. During the pouring process, the driving motor 56 is started to drive the spline rod 58 and the cam 59 to rotate synchronously. During the continuous rotation of the cam 59, when it rotates to the concave surface, under the elastic force of the first damping spring 512, the limit block 527 and the knocking rod 511 are pushed to move inward, and when the cam 59 rotates to the convex surface, it can push the knocking rod 511 to move outward and compress the first damping spring 512. In this way, the knocking rod 511 periodically knocks the inner wall of the casting inner mold 2, so that the knocking rods 511 at different positions continuously knock different positions of the inner wall of the casting inner mold 2, so that the casting inner mold 2 generates high-frequency vibration. This vibration acts on the inside of the concrete, which can significantly improve the vibration effect inside the concrete, thereby fully compacting the concrete and removing the bubbles therein. After the cement pipe solidifies to a certain extent, the two reeling and winding motors 525 are started to drive the reeling roller 524 to rotate synchronously, so that the rotating reeling roller 524 reels the traction rope 522, and the guide wheel 523 is responsible for driving the reeling and unreeling of the traction rope 522. When the reeling roller 524 reels the traction rope 522, it pulls the sliding column 519 and the connecting rod 520 to slide on the arc frame 518 and compresses the second damping spring 521. The connecting rod 520 drives the casting inner mold 2 to rotate during the pulling process. While the casting inner mold 2 rotates, the inner wall of the cement pipe is smoothed through its outer wall. Since the casting inner mold 2 is no longer in close contact with the cement pipe, when the casting outer mold 3 is separated from the cement pipe, it can avoid damage to the cement pipe and prevent the cement pipe from collapsing, thereby better ensuring the integrity of the outer wall of the cement pipe.

[0022] Embodiment 2: Combination Figure 8As shown, based on the first embodiment, the casting outer mold 3 includes two half molds rotatably mounted on the support seat 1, the two half molds are rotatably spliced ​​into the casting outer mold 3, the outer walls of the two half molds are provided with fixing clamps 31, and the two fixing clamps 31 are provided with bolts 32.

[0023] In the embodiment of the present invention, the two half molds are controlled to rotate inwards and spliced ​​by the fixing clamp 31, and then the fixing clamp 31 is connected and fixed by the bolt 32, thereby completing the connection and fixation of the two half molds.

[0024] The working principle of the new cement pipe casting and forming equipment is as follows: the steel cage body 4 is placed into the casting inner mold 2 and the casting outer mold 3, and the screw rod 514 is driven to rotate synchronously by turning on the regulating motor 513, and the screw rod 514 drives the threaded lifting frame 52 to move downward, so that when the positioning frame 53, the fixing ring 54, the connecting plate 55, and the spline rod 58 move downward, the spline rod 58 is engaged with the spline groove 517 of the positioning rod 516, thereby completing the positioning processing of the lifting frame 52, the positioning frame 53, the fixing ring 54, the connecting plate 55, and the spline rod 58; At the same time, the positioning holes 57 on the positioning frame 53 are engaged with the steel bars of the steel cage body 4, so that the steel cage body 4 is positioned by using the positioning holes 57 of the positioning frame 53, so that the position of the steel cage body 4 can be centered, so that the steel cage body 4 is located between the casting inner mold 2 and the casting outer mold 3, so as to avoid the movement of the steel cage during the casting process. If its position deviates from the center, the cement pipe may have uneven stress distribution when subjected to force, which will cause some parts of the cement pipe to bear excessive pressure, while other parts may bear less pressure, thereby reducing the overall load-bearing capacity, and the deviation of the steel cage may cause gaps or cracks in the cement pipe, which will become channels for the penetration of moisture and corrosive substances, accelerating the aging and damage of the cement pipe, especially in a humid or corrosive environment, this effect will be more significant; Then, cement is poured to form a cement pipe, and the driving motor 56 is turned on to drive the spline rod 58 and the cam 59 to rotate synchronously. During the continuous rotation of the cam 59, when the cam 59 rotates to the concave surface, under the elastic force of the first damping spring 512, the limit block 527 and the knocking rod 511 are pushed to move inward. When the cam 59 rotates to the convex surface, the knocking rod 511 can be pushed to move outward and the first damping spring 512 is compressed, so that the knocking rod 511 knocks the inner wall of the casting inner mold 2. This reciprocating process allows the knocking rods 511 at different positions to continuously knock different positions of the inner wall of the casting inner mold 2, so that the casting inner mold 2 generates high-frequency vibration, which acts on the inside of the concrete after vibration, and the vibration effect inside the concrete is improved, thereby fully compacting it and removing bubbles. After the cement pipe solidifies to a certain extent, the two reeling and unreeling motors 525 are turned on to drive the reeling roller 524 to rotate synchronously, so that the rotating reeling roller 524 reels the traction rope 522, and the guide wheel 523 drives the reeling and unreeling of the traction rope 522. When the reeling roller 524 reels the traction rope 522, the traction rope 522 pulls the sliding column 519 and the connecting rod 520 to slide on the arc frame 518, and compresses the second damping spring 521, so that the connecting rod 520 drives the casting inner mold 2 to rotate. While rotating, the casting inner mold 2 will smooth the inner wall of the cement pipe through its outer wall, so that the casting inner mold 2 will no longer be tightly attached to the cement pipe, and the casting outer mold 3 will not damage the cement pipe when it is separated from the cement pipe, so that the cement pipe can be prevented from collapsing, and the integrity of the outer wall of the cement pipe can be better guaranteed. Then control the lifting frame (52) and the positioning frame 53 to move upward, open the casting outer mold 3 and take out the cement pipe.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
