Description

Technical Field

[0001] This utility model belongs to the field of New Jersey fence production technology, specifically relating to automated production equipment for prefabricated New Jersey fences. Background Technology

[0002] New Jersey (concrete) guardrails are wall-type guardrails with a specific cross-sectional shape. Their characteristics are: when a car collides with the guardrail, under the instantaneous moving load, the guardrail remains essentially stationary and undeformed (rigid state). The energy during the collision is mainly absorbed by the car climbing along the guardrail surface and turning during the contact process. Simultaneously, the colliding car returns to its normal driving direction. Currently, New Jersey guardrails are typically manufactured using specialized prefabricated automated production equipment.

[0003] Existing equipment typically moves a mold on the production line and vibrates the entire structure after pouring concrete inside to make it dense, thus achieving basic production of New Jersey guardrails. However, the concrete at the mold opening still relies on traditional manual methods for smoothing. This method is not only inefficient but also inconsistent, resulting in insufficient surface flatness and poor edge forming quality of the New Jersey guardrails, making it difficult to meet high-standard production requirements. Utility Model Content

[0004] In view of this, the present invention provides an automated production equipment for prefabricated New Jersey guardrails, which can replace traditional manual operation with an automated smoothing mechanism, significantly improving smoothing efficiency and consistency, and ensuring the surface flatness and edge forming quality of the New Jersey guardrails.

[0005] To address the aforementioned technical problems, this utility model provides an automated production equipment for precast New Jersey guardrails, including support legs and a smoothing mechanism mounted thereon. The smoothing mechanism is used to smooth the concrete at the opening of the precast New Jersey guardrail mold. The smoothing mechanism includes a rectangular sliding cylinder slidably connected to the upper end of the support legs. A rectangular sliding rod is slidably connected within a rectangular groove at the upper end of the rectangular sliding cylinder. One end of the rectangular sliding rod is provided with an installation rod, and the lower end of the installation rod is slidably connected to a smoothing plate. The upper end of the rectangular sliding cylinder is also provided with a drive component for driving the rectangular sliding rod to reciprocate. That is, by replacing traditional manual operation with automated smoothing, the smoothing efficiency and consistency are significantly improved, ensuring the flatness of the New Jersey guardrail surface and the edge forming quality. This not only reduces labor costs but also significantly shortens the production cycle, providing a reliable guarantee for the mass and standardized production of precast components.

[0006] The drive assembly includes a mounting cavity located at the upper end of a rectangular sliding cylinder, which is connected to a rectangular sliding groove. A rectangular frame plate is provided at the upper end of the rectangular sliding rod. A rotating plate is rotatably connected to the upper end of the mounting cavity, and a protruding post is rotatably connected to the end of the rotating plate. The protruding post slides in cooperation with the rectangular frame plate, thereby driving the rectangular sliding rod to move back and forth.

[0007] The drive assembly also includes a motor located at the top of the rectangular sliding cylinder. The output shaft of the motor is fixedly connected to the rotating plate, thus providing a drive source for the rotating plate.

[0008] It also includes a vibration assembly, which provides a vibration source for the smearing plate. The vibration assembly includes vibration motors symmetrically arranged at both ends of the upper part of the smearing plate, which provide the vibration source.

[0009] The vibration assembly also includes springs located at both ends of the lower part of the mounting rod. The lower ends of the springs are fixedly connected to the trowel plate, thus providing elastic force.

[0010] The upper end of the support leg is equipped with an electric push rod. The telescopic end of the electric push rod is fixedly connected to the upper end of the inner cavity of the rectangular sliding cylinder, thereby adjusting the relative height of the smearing plate.

[0011] The four sides of the trowel are all upturned, which can prevent concrete from overflowing during the troweling process and also create a smooth edge with regular edges.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. First, the support leg and its auxiliary mechanism are fixedly installed on one side of the precast New Jersey fence automated production line. After concrete is poured into the precast New Jersey fence mold, the electric push rod is activated, and its telescopic end extends to drive the rectangular sliding cylinder to move along the support leg, thereby adjusting the relative height of the trowel plate so that the trowel plate accurately fits the mold opening. This can adapt to the height requirements of different mold specifications, improving the equipment's versatility. At this time, the New Jersey fence mold with poured concrete moves at a uniform speed on the production line. Simultaneously, the motor is started, and its output shaft drives the rotating plate to rotate. When the rotating plate rotates, through the sliding cooperation between the convex column and the rectangular frame plate, it drives the rectangular sliding rod to move back and forth along the rectangular slide groove, thereby pushing the installation rod and the trowel plate to smooth the concrete surface. By replacing traditional manual operation with automated smoothing, smoothing efficiency and consistency are significantly improved, ensuring the flatness of the New Jersey fence surface and the edge forming quality. This not only reduces labor costs but also greatly shortens the production cycle, providing a reliable guarantee for the mass and standardized production of precast components.

[0013] 2. During this process, the vibrating motor generates high-frequency vibration and transmits it to the troweling plate through the spring, which effectively eliminates air bubbles on the concrete surface and improves the density. The upward-curving design of the four sides of the troweling plate can prevent concrete from overflowing during the troweling process and also create a smooth troweling effect with regular edges.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides automated production equipment for prefabricated New Jersey guardrails, such as... Figure 1-4As shown: The system includes a support leg 100 and a smoothing mechanism mounted thereon. The support leg 100 and its associated mechanisms are fixedly installed on one side of the precast New Jersey guardrail automated production line. The smoothing mechanism is used to smooth the concrete at the opening of the precast New Jersey guardrail mold. The smoothing mechanism includes a rectangular sliding cylinder 101 slidably connected to the upper end of the support leg 100. A rectangular sliding rod 102 is slidably connected within a rectangular groove at the upper end of the rectangular sliding cylinder 101. One end of the rectangular sliding rod 102 is provided with an installation rod 103, and the lower end of the installation rod 103 is slidably connected to a smoothing plate 104. The rectangular sliding cylinder 10... The upper end of 1 is also provided with a drive assembly for driving the rectangular sliding rod 102 to reciprocate. The drive assembly includes a mounting cavity 200 disposed at the upper end of the rectangular sliding cylinder 101, the mounting cavity 200 being connected to the rectangular slide groove, a rectangular frame plate 201 disposed at the upper end of the rectangular sliding rod 102, a rotating plate 202 being rotatably connected to the upper end of the mounting cavity 200, a protruding post 203 being rotatably connected to the end of the rotating plate 202, the protruding post 203 being slidably engaged with the rectangular frame plate 201, and the drive assembly also includes a motor 204 disposed at the upper end of the rectangular sliding cylinder 101, the output shaft of the motor 204 being fixedly connected to the rotating plate 202.

[0018] After concrete is poured into the precast New Jersey fence mold, the trowel 104 is precisely fitted into the mold opening. At this time, the New Jersey fence mold with poured concrete moves at a constant speed on the production line. Simultaneously, the motor 204 is started, and its output shaft drives the rotating plate 202 to rotate. When the rotating plate 202 rotates, it drives the rectangular sliding rod 102 to move back and forth along the rectangular groove through the sliding engagement of the protruding post 203 and the rectangular frame plate 201. This pushes the mounting rod 103 and the trowel 104 to smooth the concrete surface. Automated smoothing replaces traditional manual operation, significantly improving smoothing efficiency and consistency, ensuring the flatness of the New Jersey fence surface and the edge forming quality. It not only reduces labor costs but also greatly shortens the production cycle, providing a reliable guarantee for the mass and standardized production of precast components.

[0019] like Figure 1-4 As shown, it also includes a vibration assembly, which provides a vibration source for the smearing plate 104. The vibration assembly includes vibration motors 300 symmetrically arranged at both ends of the upper part of the smearing plate 104. The vibration assembly also includes springs 301 respectively arranged at both ends of the lower part of the mounting rod 103. The lower ends of the springs 301 are fixedly connected to the smearing plate 104. Both ends of the upper part of the smearing plate 104 are provided with circular grooves corresponding to the mounting rods 103. The springs 301 are respectively located in the circular grooves on the same side.

[0020] The vibrating motor 300 generates high-frequency vibrations, which are transmitted to the trowel plate 104 through the spring 301, effectively eliminating air bubbles on the concrete surface and improving its density.

[0021] like Figure 2As shown, the upper end of the support leg 100 is provided with an electric push rod 400. The upper end of the support leg 100 is provided with a fixing groove for providing fixed support for the electric push rod 400. The telescopic end of the electric push rod 400 is fixedly connected to the upper end of the inner cavity of the rectangular sliding cylinder 101. When the electric push rod 400 is started, its telescopic end extends and drives the rectangular sliding cylinder 101 to move along the support leg 100, thereby adjusting the relative height of the smearing plate 104 so that the smearing plate 104 accurately fits the mold opening. This can adapt to the height requirements of molds of different specifications and improve the versatility of the equipment.

[0022] like Figure 1-3 As shown, all four sides of the trowel 104 are upturned. The upturned design of the four sides of the trowel 104 can prevent concrete from overflowing during the troweling process and can also create a smooth troweling effect with regular edges.

[0023] The working principle of the precast New Jersey fence automated production equipment provided by this utility model is as follows: First, the support leg 100 and its auxiliary mechanism are fixedly installed on one side of the precast New Jersey fence automated production line. After concrete is poured into the precast New Jersey fence mold, the electric push rod 400 is started, and its telescopic end extends to drive the rectangular sliding cylinder 101 to move along the support leg 100, thereby adjusting the relative height of the trowel plate 104 so that the trowel plate 104 accurately fits the mold opening, which can adapt to the height requirements of different mold specifications and improve the versatility of the equipment. At this time, the New Jersey fence mold with the poured concrete moves at a uniform speed on the production line. At the same time, the motor 204 is started, and its output shaft drives the rotating plate 202 to rotate. When the rotating plate 202 rotates, it connects with the rectangular frame plate 202 through the protrusion 203. The sliding engagement of 01 drives the rectangular sliding rod 102 to reciprocate along the rectangular groove, thereby pushing the mounting rod 103 and the trowel 104 to smooth the concrete surface. During this process, the vibrating motor 300 generates high-frequency vibration and transmits it to the trowel 104 through the spring 301, effectively eliminating air bubbles on the concrete surface and improving density. The upward-curving design of the four sides of the trowel 104 can prevent concrete from overflowing during the smoothing process and also create a smoothing effect with regular edges. By replacing traditional manual operation with automated smoothing, the smoothing efficiency and consistency are significantly improved, ensuring the flatness of the New Jersey guardrail surface and the edge forming quality. This not only reduces labor costs but also greatly shortens the production cycle, providing a reliable guarantee for the mass production and standardization of precast components.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
