Description

Technical Field

[0001] This invention relates to a New Jersey guardrail molding and transfer device, belonging to the technical field of New Jersey guardrail transfer equipment. Background Technology

[0002] New Jersey guardrails are a type of wall-like barrier widely used on roads, made of grouted concrete, to separate lanes on highways.

[0003] New Jersey guardrails require mold making, and after production, they need to be demolded and transported. For flat mold boxes, demolding involves two steps: lifting and flipping. Existing demolding processes typically involve building a large gantry-type fixed frame on the production line. A vacuum unit with vacuum suction cups is mounted on a moving slide on the frame, using negative pressure suction to vertically lift the guardrail from the mold box. Then, the moving slide moves horizontally along the frame guide rails, and the guardrail is flipped 90° before being placed vertically on the ground. Patent application number 202311420999.0, entitled "A Fully Automatic New Jersey Guardrail Demolding, Transporting, and Tilting Vacuum Suction Cup Machine," describes this type of demolding device. After demolding, the transport process utilizes forklifts or other transport vehicles.

[0004] In the aforementioned mold-making and transfer process, the equipment is fixed and lacks flexibility; moreover, the mold-making and transfer processes are carried out using different equipment in a series of steps, affecting production efficiency. In addition, sometimes New Jersey guardrails require date markings to be applied to the sides, a task that is usually done manually by workers using digital templates and spray paint cans, which is time-consuming and labor-intensive.

The front end of the track beam 4 is suspended in front of the car body 1, and the middle and rear ends are fixed on the corresponding columns 3. Each end of the two track beams 4 is connected to an end beam 401. Both ends of the walking beam 5 are provided with walking mechanisms 501, and the walking mechanisms 501 cooperate with the walking rails 402 on the top surface of the two track beams 4. The walking beam 5 is connected to the mounting frame 7, which is parallel to the walking beam 5, through two telescopic sleeves 6. The two ends of the mounting frame 7 extend downward to form mounting legs 701. The two ends of the airbag device 8 are rotatably connected to the two mounting legs 701. A flipping cylinder 10 for controlling the flipping of the airbag device 8 is provided between the airbag device 8 and the mounting frame 7. The vehicle body 1 is provided with telescopic support devices 9 on both sides that extend forward and support the ground. like Figures 13-19 As shown, the spraying and marking device 11 includes a spraying device and a conversion device that drives the spraying device to rotate and retract.

The press nozzle of the spray can 1105 is directly facing the multiple hollowed-out number templates 1108.

[0047] The spray can 1105 is detachably mounted on the second mounting plate for easy replacement. Multiple perforated number templates 1108 form date information, which can be changed by replacing one or more perforated number templates 1108. Driven by the transverse ball screw 1103, the spray can 1105 can pass laterally through all the perforated number templates 1108. Under the action of the electromagnetic push rod 1106, the spray can 1105 sprays paint onto the side of the New Jersey fence, and under the action of the multiple perforated number templates 1108, the date information is formed on the side of the New Jersey fence, completing the spray marking.

[0048] The painting device is to mark the side of the New Jersey guardrail during the guardrail molding process. When the mounting frame 7 places the New Jersey guardrail onto the vehicle body 1, the painting device may interfere with the post 3.

The first mounting plate 1101 in the painting device is fixed to the nuts of the vertical slider 1123 and the vertical ball screw 1120.

[0050] In the above structural description, the descriptions of directions such as "vertical" and "horizontal" are based on the working state of the spraying and marking device 11.

[0051] The top surface of the vehicle body 1 is provided with a plurality of placement grooves 105, which are adapted to the bottom of the New Jersey guardrail.

[0052] The telescopic support device 9 includes a horizontal telescopic beam 901 and a vertical telescopic leg 902. The horizontal telescopic beam 901 is fixed on the vehicle body 1, and the vertical telescopic leg 902 is installed at the telescopic end of the horizontal telescopic beam 901.

[0053] The telescopic support device 9 extends forward and backward and supports the ground. The horizontal telescopic beam 901 is a telescopic beam that extends and retracts at both ends, and vertical telescopic legs 902 are installed on both telescopic ends.

[0054] The wheel 2 can be a regular wheel, and the entire invention is oriented with the upper and lower sides of the New Jersey guardrail as the front.

[0055] The wheel 2 can also be an AGV steering wheel, allowing the whole vehicle to move in any direction.

[0056] like Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown (the spraying and marking device 11 has been removed from the figure to show the relevant structure more clearly), the airbag device 8 includes a connecting beam 801, multiple airbags 802 and a vacuum machine 803. The two ends of the connecting beam 801 are rotatably connected to the mounting legs 701 at both ends of the mounting frame 7. The multiple airbags 802 are fixed in parallel on the connecting beam 801. The vacuum machine 803 is fixed on the mounting frame 7 and is connected to the multiple airbags 802 through pipelines. The mounting bracket 7 is provided with a mounting seat 702, and the connecting beam 801 is provided with a mounting ear 804. One end of the tilting cylinder 10 is hinged to the mounting seat 702, and the other end is hinged to the mounting ear 804.

[0057] like Figure 10 , Figure 11 , Figure 12 As shown, the rear end and both sides of the vehicle body 1 are provided with fixed fences 101, and the front end is provided with a movable fence 102. The movable fence 102 is hinged to the front end of the vehicle body 1 and is controlled to rotate by two motors 103. Locking devices 104 are provided between the two ends of the movable fence 102 and the fixed fences 101 on both sides of the vehicle body 1.

[0058] The locking device 104 includes a locking rod 1041, a locking ring 1042, and an electric telescopic rod 1043. The middle part of the locking rod 1041 is rotatably connected to the movable fence 102, and the locking ring 1042 is fixed to the fixed fence 101. One end of the locking rod 1041 is a hook and hooks into the locking ring 1042, and the other end is connected to the telescopic rod end of the electric telescopic rod 1043. The cylinder of the electric telescopic rod 1043 is fixed to the movable fence 102.

[0059] like Figure 20 As shown, the working process of this invention is as follows.

[0060] In the first step, the entire invention moves using wheels 2, approaching the New Jersey guardrail mold box to be demolded, with the front of the vehicle body 1 facing the top of the New Jersey guardrail. After approaching to a certain distance, it stops, and the electric telescopic rods 1043 at both ends of the movable fence 102 actuate, causing the locking rod 1041 to rotate, so that the hook end of the locking rod 1041 disengages from the locking ring 1042. At this time, the two ends of the movable fence 102 are unlocked from the fixed fence 101, and the motor 103 rotates, causing the movable fence 102 to flip down. After the movable fence 102 has completely flipped down, the entire invention continues to move towards the New Jersey guardrail mold box, getting close to it.

[0061] The second step involves the horizontal telescopic beam 901 extending from the telescopic support device 9, the vertical telescopic leg 902 supporting the ground, and the traveling beam 5 moving to the front end of the track beam 4, positioning the airbag device 8 directly above the New Jersey guardrail. At this point, the airbag device 8 is in a horizontally downward position, and the telescopic sleeve 6 extends, pressing the airbag device 8 against the New Jersey guardrail. Simultaneously, the vacuum machine 803 starts to create a vacuum, ensuring the New Jersey guardrail is firmly attached to the airbag device 8. Then, the telescopic sleeve 6 retracts, lifting the New Jersey guardrail. After being lifted into position, the tilting cylinder 10 extends... The airbag device 8 is pushed to rotate 90° towards the vehicle body 1. Then, the traveling beam 5 is controlled to move towards the vehicle body 1 and move to the first placement position of the New Jersey guardrail, that is, above the placement groove 105 at the rear end of the vehicle body 1. The telescopic sleeve 6 extends and places the New Jersey guardrail in the placement groove 105. Then, the vacuum machine 803 depressurizes, the airbag device 8 releases the New Jersey guardrail, the telescopic sleeve 6 retracts, driving the airbag device 8 to rise. The tilting cylinder 10 retracts, so that the airbag device 8 returns to the horizontal downward position, thus completing the demolding and loading of one New Jersey guardrail.

[0062] The third step is to retract the telescopic support device 9, and the entire invention moves to the next New Jersey guardrail mold box to be demolded via the wheels 2 and gets close to it.

[0063] Fourth step, repeat the second step above to complete the molding and loading of the second New Jersey fence piece. The loading position is in the second placement groove 105 adjacent to the first New Jersey fence piece.

[0064] Fifth, based on the number of grooves 105 placed on vehicle body 1, repeat steps three and four above to load the corresponding number of New Jersey guardrails.

[0065] Step 6: After loading, retract the telescopic support device 9. The entire invention moves backward a distance, the motor 103 reverses, and drives the movable fence 102 to flip up and reset. After resetting, the electric telescopic rod 1043 moves, driving the locking rod 1041 to rotate. The hook end of the locking rod 1041 hooks the locking ring 1042, completing the locking of the movable fence 102.

[0066] In the seventh step, the entire invention is transported via wheels 2 to move the New Jersey guardrails. Once at the designated location, the movable fence 102 is lowered, and through the coordination of the telescopic support device 9, the traveling beam 5, the telescopic sleeve 6, and the airbag device 8, the New Jersey guardrails are unloaded one by one and placed in the designated position. This completes the combined work of molding and transporting multiple New Jersey guardrails.

[0067] If a date mark needs to be applied to the side of the New Jersey guardrail, in the second step above, after lifting into position, extend the tilting cylinder 10, push the airbag device 8 to rotate 90° towards the vehicle body 1, so that the New Jersey guardrail is in a vertical position, and then start the spraying and marking device. First, start the drive unit 1113, which drives the support plate 1111 to rotate via the connecting plate 1122, making the other end of the support plate 1111 parallel to the side of the New Jersey fence. Then, start the gear motor 1116, which drives the fourth mounting plate 1118 to rotate downwards by 90°. Then, start the height adjustment motor 1119, which moves the first mounting plate 1101 downwards to a suitable position. At this time, the template frame 1107 is in a position close to the side of the New Jersey fence. Start the lateral travel motor 1102 and the electromagnetic push rod 1106. The lateral ball screw 1103 drives the spray can 1105 to travel laterally, passing through all the hollowed-out number templates 1108 in sequence. At the same time, the electromagnetic push rod 1106 presses down on the spray nozzle of the spray can 1105, causing the spray can 1105 to spray paint during the lateral travel. Under the action of multiple hollowed-out number templates 1108, date information is formed on the side of the New Jersey fence. After the spraying is completed, the electromagnetic push rod 1106 is reset, the transverse travel motor 1102 reverses, driving the self-spraying can 1105 to reset, and then the height adjustment motor 1119, gear motor 1116, and drive device 1112 move in reverse order, driving the spraying and marking device 11 to reset as a whole, thus completing one spraying and marking operation. Then the traveling beam 5 can be controlled to move in the opposite direction to the vehicle body 1 to complete the subsequent work.

[0068] During the aforementioned spraying and marking process, ball screws and guide rods were used for height adjustment and lateral movement to ensure stability during movement. Additionally, multiple perforated number templates 1108 are replaceable to create different date information.
