Description

Technical Field

[0001] This utility model relates to the field of corrugated guardrail installation technology, specifically to a corrugated guardrail auxiliary installation vehicle with a hydraulic lifting device. Background Technology

[0002] Corrugated beam guardrails are a major form of semi-rigid guardrails. They are a continuous structure made of interlocking corrugated guardrail panels supported by posts. Corrugated guardrails serve as highway crash barriers, consisting of two corrugated beam steel guardrail panels and two guardrail posts positioned between them. Their primary purpose is to prevent out-of-control vehicles from running off the road, protecting vehicles and passengers and reducing accident losses. In highway and mountainous infrastructure construction, corrugated guardrails are crucial safety protection facilities, and their installation quality directly affects road safety. Currently, auxiliary installation vehicles are required during the installation and transportation of corrugated guardrails.

[0003] Based on the above, the inventors of this application have discovered the following problems: the current auxiliary installation vehicle lacks a support structure. When the corrugated guard plate is placed, the center of gravity is easily shifted, resulting in one side having greater pressure and the other side having less pressure, forming an unbalanced state similar to a seesaw. During transportation, two workers are required to manually support both ends to keep it balanced, which is very inconvenient to operate.

[0004] Therefore, in view of this, this application proposes an auxiliary installation vehicle for wave-shaped guardrails with a hydraulic lifting device to improve upon the existing structure and its shortcomings, aiming to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a corrugated guardrail auxiliary installation vehicle with a hydraulic lifting device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is: a wave-shaped guardrail auxiliary installation vehicle with a hydraulic lifting device, including a lifting component, a fixing component, and a support component. The fixing component is disposed at the upper end of the lifting component, and the support component is disposed on opposite sides of the outer side of the lifting component. The lifting component is used to drive the fixing component to rise or fall according to the installation height. The fixing component is used to fix the guardrail. The support component is used to increase the contact area between the fixing component and the guardrail. The support component includes a pair of electric slide rails, and electric sliders are slidably connected to the outer side of each pair of electric slide rails. Mounting seats are installed on opposite sides of each pair of electric sliders. Rotating seats are rotatably connected to the bottom ends of the two mounting seats. A support seat is installed at one end of the rotating seat. A groove is formed on the top surface of the support seat. The lifting component includes a base, and a lifting platform is provided at the upper end of the base. The opposite outer sides of the lifting platform are respectively fixedly connected to the outer walls of the pair of electric slide rails.

[0007] Furthermore, servo motors are installed at the upper ends of the two mounting seats. The output ends of the two servo motors are respectively connected to the two rotating seats through transmission. The output ends of the two servo motors have the same rotational speed and opposite rotational directions.

[0008] The beneficial effect of adopting the above further solution is that by setting two servo motors with the same rotational speed and opposite rotational directions, when the two servo motors work, they can accurately control the synchronous reverse rotation of the two rotating seats. The rotating seats drive the support seats to flexibly adjust the angle, so that the support seats stored on both sides of the lifting platform are unfolded into an "I" shape, making the grooves of the support seats better fit the bottom surface of the guardrail, ensuring the stability of the support, making the support of the guardrail by the support component more adaptable and tighter, effectively dispersing the pressure of the guardrail, and preventing the guardrail from being in an unbalanced state similar to a seesaw due to the deviation of the center of gravity, resulting in greater pressure on one side and smaller pressure on the other side; at the same time, the setting of two servo motors with the same rotational speed and opposite rotational directions can always keep the angle adjustment of the two support seats coordinated, and there will be no situation where one side is adjusted too much and the other side is adjusted insufficiently.

[0009] Furthermore, the moving speeds of the two electric slide rails driving the electric sliders are the same, and the moving directions of the two electric slide rails driving the electric sliders are the same.

[0010] The beneficial effect of adopting the above further solution is that the same moving speed and the same moving direction of the two electric slide rails driving the electric sliders can ensure that the two electric sliders drive the mounting seats, rotating seats, support seats, etc. to move synchronously. After the two electric sliders drive the corrugated guardrail close to the first baffle, the two second electric telescopic rods are used to push the moving plate and the corrugated guardrail to fit the side opposite to the first baffle.

[0011] Furthermore, the fixing component includes a first baffle and a second baffle. The first baffle and the second baffle are respectively installed on both sides of the top surface of the lifting platform. There is a distance between the first baffle and the second baffle. A moving plate is slidably arranged between the first baffle and the second baffle. A pair of second electric telescopic rods are installed on the side of the second baffle away from the moving plate. The movable ends of the pair of second electric telescopic rods all penetrate through the second baffle and extend to the outside, and are fixedly connected to the moving plate.

[0012] The beneficial effect of adopting the above further solution is that the telescopic amounts and telescopic speeds of the movable ends of the two second electric telescopic rods are the same. When the two second electric telescopic rods are started, they can push the moving plate to slide between the first baffle and the second baffle, facilitating the adjustment of the distance between the moving plate and the first baffle according to the thickness of the guardrail to adapt to guardrails of different specifications; when fixing the guardrail, through the cooperation of the moving plate and the first baffle, the guardrail is clamped from both sides, providing a stable fixing foundation for subsequent accurate installation.

[0013] Furthermore, a pair of diagonal bars are installed on the side of the second baffle away from the moving plate and between a pair of second electric telescopic rods, and the ends of the pair of diagonal bars away from the second baffle are fixedly connected to the top surface of the lifting platform.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, by setting two diagonal bars, the diagonal bars, the second baffle, and the lifting platform form a triangular support structure. The triangle has stability and can greatly enhance the structural strength of the second baffle.

[0015] Furthermore, a pair of first fixed seats are installed on one side of the inner bottom of the base, and a pair of second fixed seats are slidably connected to the inner bottom of the base away from the first fixed seats. A first connecting rod is hinged to the outside of the pair of first fixed seats, and a first connecting seat is hinged to the end of the pair of first connecting rods away from the first fixed seats. A second connecting rod is hinged to the outside of the pair of second fixed seats, and a second connecting seat is hinged to the end of the pair of second connecting rods away from the second fixed seats. The upper ends of the two first connecting seats and the two second connecting seats are fixedly connected to the bottom of the lifting platform.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the first link and the second link, the first link, the second link, the first fixed seat, the second fixed seat, the first connecting seat, and the second connecting seat constitute a scissor-like lifting structure.

[0017] Furthermore, the adjacent first and second connecting rods are hinged by a pin. The base has a hinge seat installed at its inner bottom end between a pair of second fixed seats. A first electric telescopic rod is hinged inside the hinge seat. The movable end of the first electric telescopic rod is hinged to a connecting rod through a movable seat. The two ends of the connecting rod are respectively fixedly connected to the outer walls of a pair of second connecting rods.

[0018] The beneficial effect of adopting the above-mentioned further solution is that when the first electric telescopic rod is started, its movable end pushes the connecting rod through the movable seat. The connecting rod drives a pair of second connecting rods fixedly connected to it to move synchronously. Since the second connecting rod is hinged to the second fixed seat, and the second fixed seat can slide inside the bottom of the base, the second connecting rod will rotate around the hinge point with the second fixed seat and push the second fixed seat to slide away from the first fixed seat. Since the first connecting rod and the second connecting rod are hinged by a pin, the rotation of the second connecting rod will drive the first connecting rod to move synchronously. The first connecting rod rotates around the hinge point with the first fixed seat, and the first fixed seat is fixed and does not slide. As the intersection angle of the first connecting rod and the second connecting rod gradually increases, the upper ends of the first connecting rod and the second connecting rod respectively drive the lifting platform to rise smoothly upward through the first connecting seat and the second connecting seat. Conversely, when the first electric telescopic rod retracts, the movable end pulls the connecting rod, causing the second connecting rod to rotate in the opposite direction. The second fixed seat slides towards the first fixed seat, the intersection angle of the first connecting rod and the second connecting rod decreases, and the lifting platform descends accordingly.

[0019] Furthermore, casters are installed at the four corners of the bottom of the base, and a push rod is installed on the top surface of the base on the side away from the lifting platform.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the push rod and the caster wheels, the push rod makes it easy for workers to push the installation vehicle, and with the help of the caster wheels, the moving direction and moving path of the installation vehicle can be easily controlled.

[0021] Furthermore, an electrical control box is installed on one side of the top surface of the base, located in the middle of the push rod. The electrical control box contains a wireless receiving module, a microcontroller module, a relay, and a battery.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the frequency band of the wireless receiving module is matched with that of the external device remote control; when the user presses the remote control button, the wireless receiving module transmits a "extend" wireless signal to the wireless receiving module, the wireless receiving module captures the signal and transmits it to the microcontroller, the microcontroller parses the instruction and outputs a control signal to the relay, the relay connects the power supply to the motor inside the electric telescopic pole, so that the electric telescopic pole performs the "extend" action.

[0023] Compared with the prior art, the advantages and beneficial effects of this utility model are:

[0024] The wave guardrail auxiliary installation vehicle with a hydraulic lifting device of the present utility model, by setting a support component, after the support seats on both sides of the lifting platform are unfolded and in an "I" shape, the bottom of the wave guardrail to be installed is aligned with the grooves of a pair of support seats and inserted, ensuring the stability of the support. A pair of support seats can effectively disperse the pressure of the guardrail, avoiding the situation where one side of the wave guardrail has a large pressure and the other side has a small pressure due to the deviation of the center of gravity, forming an unbalanced state similar to a seesaw; by setting support components on both sides of the center position of the wave guardrail, after increasing the contact area, the gravity of the guardrail plate can be more evenly dispersed to the support components. Originally, the bent guardrail plate may have a large pressure on one side and a small pressure on the other side due to the deviation of the center of gravity, forming an unbalanced state similar to a seesaw. After adding the support components,着力点 are added to the guardrail, which can better balance the center of gravity of the guardrail plate and reduce the inclination caused by the deviation of the center of gravity.

[0032] Embodiment:

Mounting seats 33 are installed on the opposite sides of the pair of electric sliders 32. Rotating seats 34 are rotatably connected to the bottom ends of the two mounting seats 33. A supporting seat 35 is installed at one end of the rotating seat 34. A groove 36 is formed on the top surface of the supporting seat 35. The lifting component 1 includes a base 11. A lifting platform 12 is arranged at the upper end of the base 11. The opposite outer sides of the lifting platform 12 are respectively fixedly connected to the outer walls of the pair of electric slide rails 31. Servo motors 37 are installed on the upper ends of the two mounting seats 33. The output ends of the two servo motors 37 are respectively connected to the two rotating seats 34 in a transmission manner. The output end rotation speeds of the two servo motors 37 are the same and the rotation directions are opposite. The moving speeds of the two electric slide rails 31 driving the electric sliders 32 are the same, and the moving directions of the two electric slide rails 31 driving the electric sliders 32 are the same. When the two servo motors 37 work, the two rotating seats 34 can be accurately controlled to rotate synchronously and in opposite directions. The rotating seat 34 drives the supporting seat 35 to flexibly adjust the angle, so that the supporting seats 35 stored on both sides of the lifting platform 12 are unfolded into an "I" shape. After aligning the bottom of the waveform guard plate to be installed with the grooves 36 of the pair of supporting seats 35 and inserting it, the stability of the support can be ensured. The pair of supporting seats 35 can effectively disperse the pressure of the guardrail, avoiding the situation that one side of the waveform guardrail has a large pressure and the other side has a small pressure due to the deviation of the center of gravity, forming an unbalanced state similar to a seesaw; the same moving speed and the same direction of the two electric slide rails 31 driving the electric sliders 32 can ensure that the two electric sliders 32 drive the mounting seats 33, the rotating seats 34 and the supporting seats 35 to move synchronously. After the two electric sliders 32 drive the waveform guardrail to approach the first baffle 21, the moving plate 25 and the waveform guardrail are pushed by the two second electric telescopic rods 24 to be in contact with the side of the first baffle 21 opposite to the waveform guardrail to complete the fixation.

[0034] Please see Figures 1-5 This utility model also provides a technical solution: the fixing component 2 includes a first baffle 21 and a second baffle 22, which are respectively installed on both sides of the top surface of the lifting platform 12. There is a distance between the first baffle 21 and the second baffle 22. A movable plate 25 is slidably provided between the first baffle 21 and the second baffle 22. A pair of second electric telescopic rods 24 are installed on the side of the second baffle 22 away from the movable plate 25. The movable ends of the pair of second electric telescopic rods 24 extend through the second baffle 22 to the outside and are fixedly connected to the movable plate 25. A pair of diagonal rods 23 are installed on the side of the baffle 22 away from the movable plate 25 and between a pair of second electric telescopic rods 24. The ends of the pair of diagonal rods 23 away from the second baffle 22 are fixedly connected to the top surface of the lifting platform 12. When the two second electric telescopic rods 24 are activated, the movable plate 25 can be pushed to slide between the first baffle 21 and the second baffle 22, so that the distance between the movable plate 25 and the first baffle 21 can be adjusted according to the thickness of the guardrail to adapt to guardrails of different specifications. When the guardrail is fixed, the guardrail is clamped from both sides by the cooperation of the movable plate 25 and the first baffle 21.

[0035] Please see Figures 1-5This utility model also provides a technical solution: a pair of first fixed seats 13 are installed on one side of the inner bottom end of the base 11; a pair of second fixed seats 14 are slidably connected to the inner bottom end of the base 11 away from the first fixed seats 13; a first connecting rod 15 is hinged to the outside of the pair of first fixed seats 13; a first connecting seat 17 is hinged to the end of each pair of first connecting rods 15 away from the first fixed seats 13; a second connecting rod 16 is hinged to the outside of the pair of second fixed seats 14; a second connecting seat 18 is hinged to the end of each pair of second connecting rods 16 away from the second fixed seats 14; the upper ends of the two first connecting seats 17 and the two second connecting seats 18 are fixedly connected to the bottom end of the lifting platform 12. The first connecting rod 15 and the second connecting rod 16 are hinged together by a pin. A hinge seat 19 is installed at the inner bottom of the base 11 between a pair of second fixed seats 14. A first electric telescopic rod 110 is hinged inside the hinge seat 19. The movable end of the first electric telescopic rod 110 is hinged to a connecting rod 111 via a movable seat. Both ends of the connecting rod 111 are fixedly connected to the outer walls of a pair of second connecting rods 16. Universal wheels 112 are installed at the four corners of the bottom of the base 11. A push rod 113 is installed on the top surface of the base 11 on the side away from the lifting platform 12. An electrical control box is installed on one side of the top surface of the base 11, located in the middle of the push rod 113. A wireless receiver is installed inside the electrical control box. The system includes a module, a microcontroller module, a relay, and a battery. When the first electric telescopic rod 110 is activated, its movable end pushes the connecting rod 111 through the movable seat. The connecting rod 111 drives a pair of second connecting rods 16 fixedly connected to it to move synchronously. Since the second connecting rod 16 is hinged to the second fixed seat 14, and the second fixed seat 14 can slide inside the bottom end of the base 11, the second connecting rod 16 will rotate around the hinge point with the second fixed seat 14 and push the second fixed seat 14 to slide away from the first fixed seat 13. Since the first connecting rod 15 and the second connecting rod 16 are hinged by a pin, the rotation of the second connecting rod 16 will drive the first connecting rod 15 to move synchronously. The first connecting rod 15 rotates around the hinge point with the first fixed seat 14. As the hinge point of the fixed seat 13 rotates, the first fixed seat 13 remains fixed and does not slide. As the intersection angle of the first link 15 and the second link 16 gradually increases, the upper ends of the first link 15 and the second link 16 drive the lifting platform 12 to rise smoothly upward through the first connecting seat 17 and the second connecting seat 18, respectively. With the cooperation of the push rod 113 and the universal wheel 112, the push rod 113 facilitates the staff to push the installation vehicle, and with the cooperation of the universal wheel 112, the movement direction and movement path of the installation vehicle can be easily controlled, so that the fixed corrugated guardrail is aligned with the corrugated guardrail already installed on the column for the next step of connection and installation. The frequency band of the wireless receiving module is matched with that of the external device remote control.When the user presses the remote control button to transmit a "stretch out" wireless signal to the wireless receiving module, the wireless receiving module captures the signal and transmits it to the single-chip microcomputer. The single-chip microcomputer analyzes the instruction and outputs a control signal to the relay. The relay turns on the power supply of the motor inside the electric telescopic rod, causing the electric telescopic rod to perform the "stretch out" action. The specific remote control connection method and implementation method are the content of the multi-point wireless temperature sensor with a heat-insulating probe rod with the patent authorization announcement number CN219830148U.;

[0036] Specifically, the working principle of the waveform guardrail auxiliary installation vehicle with a hydraulic lifting device of the present utility model: When in use, first start two servo motors 37 to control the two rotating seats 34 to rotate synchronously and reversely. The rotating seats 34 drive the support seats 35 to flexibly adjust the angles, so that the support seats 35 on both sides of the lifting platform 12 are unfolded into an "I" shape. After aligning the bottom of the waveform guardrail to be installed with the grooves 36 of a pair of support seats 35 and inserting it, ensure the stability of the support. A pair of support seats 35 can effectively disperse the pressure of the guardrail, avoiding the situation that one side of the waveform guardrail has a large pressure and the other side has a small pressure due to the deviation of the center of gravity, forming an unbalanced state similar to a seesaw; The same moving speed and the same direction of the two electric slide rails 31 driving the electric sliders 32 can ensure that the two electric sliders 32带动 the mounting seats 33, rotating seats 34 and support seats 35 to move synchronously. The two electric sliders 32带动 the waveform guardrail to fit with the first baffle 21. Starting two second electric telescopic rods 24 can push the moving plate 25 to slide between the first baffle 21 and the second baffle 22, facilitating adjusting the distance between the moving plate 25 and the first baffle 21 according to the thickness of the guardrail to adapt to guardrails of different specifications; When fixing the guardrail, through the cooperation of the moving plate 25 and the first baffle 21, clamp the guardrail from both sides. Push the installation vehicle through the push rod 113, and easily control the moving direction and moving path of the installation vehicle with the cooperation of the universal wheels 112. After aligning the waveform guardrail to be installed with the installed waveform guardrail, start the first electric telescopic rod 110. As the crossing angle between the first connecting rod 15 and the second connecting rod 16 gradually increases, the upper ends of the first connecting rod 15 and the second connecting rod 16 respectively带动 the lifting platform 12 to rise smoothly upward through the first connecting seat 17 and the second connecting seat 18. Continue to push the installation vehicle to align the fixed waveform guardrail with the waveform guardrail already installed on the column for the next connection installation.
