Description

Technical Field

[0001] This invention relates to vehicles, specifically to an intelligent fully automatic guardrail installation vehicle, and in particular to the mechanical parts of the guardrail installation vehicle. Background Technology

[0002] As is well known, in order to improve highway operating efficiency, highways are designed according to their classification, such as expressways and first-class highways. Expressways and first-class highways are equipped with guardrails, and the existing guardrails are usually transported by vehicle to the installation location, and then manually installed between the two posts according to the construction requirements. This construction method requires a large number of workers, and the close proximity of workers on site poses construction risks, resulting in relatively low construction efficiency and difficulty in ensuring construction quality.

[0003] Application No. 202110451234.8, invention title "An Auxiliary Installation Device for Guardrails in Highway Construction," provides a high-efficiency auxiliary installation device for guardrails used in highway construction that can clamp and fix guardrails. It includes a support frame; the support frame includes a vehicle base plate, vertical support plates, a rotating platform, a ring, and a controller. Multiple vertical support plates are provided, with one end of each plate symmetrically fixed to one side of the vehicle base plate. The rotating platform is located on the upper part of the vertical support plates. One side of the ring is fixedly connected to one side of the rotating platform, and the ring is slidably connected to the vertical support plates. The controller is fixedly connected to the upper side of one end of the vehicle base plate, and a pushing mechanism is located on the upper part of the rotating platform. The device assists in guardrail installation through a "pushing mechanism, lifting mechanism, gripping mechanism, and flipping mechanism," eliminating the need for manual lifting and placing of the guardrails in the installation position, saving manpower and improving work efficiency. The device can be driven manually, with a fourth motor rotating to drive the wheels, enabling the device to move to the working position. The controller controls the first and second motors to control the forward and backward and up and down movements of the sliding block. This movement, in turn, controls the forward and backward and up and down movements of the support arm, which in turn controls the gripping mechanism, moving it to a position where it can clamp the guardrail panel. The controller then activates the electric push rod, which extends downwards, clamping the guardrail panel between the upper and lower support arms. Further downward movement of the electric push rod causes the second gear to rotate the lower and upper support arms inwards, flipping the gripping mechanism to a suitable angle for installation. This facilitates manual installation of the guardrail panel, eliminating the need to manually lift the panel and secure it with bolts, thus improving work efficiency. The controller controls the rotation of the third motor, which in turn controls the rotation of the support arm. This allows for angle adjustment during guardrail grabbing and installation. Because the worm shaft can only drive the worm wheel, and the worm wheel cannot drive the worm shaft when subjected to external force, the worm wheel and worm shaft effectively control and fix the rotating shaft when it is subjected to external force. Both the upper and lower anti-slip blocks are made of rubber, which increases friction and prevents the guardrail from slipping after being gripped.

[0004] Application No. 202220018341.1, invention title "A Highway Construction Guardrail Installation Device", includes two sets of bases, and further includes: a sleeve, rotatably mounted on the base; a threaded rod, assembled inside the sleeve, with a limiting seat for limiting the guardrail at its top end, wherein the base is provided with a driving component for driving the sleeve to rotate; a telescopic cylinder and a telescopic rod, respectively installed on the side wall of the base, with the end of the telescopic rod away from the base passing through the telescopic cylinder; a slider, assembled inside the telescopic cylinder and fixedly connected to one end of the telescopic rod; through the telescopic rod and slider, in conjunction with multiple sets of equidistantly arranged mounting slots on the telescopic cylinder, the distance between the two sets of bases can be easily adjusted according to guardrails of different lengths; by driving the threaded rod upward through the sleeve, the height of the guardrail can be adjusted. 1. In this highway construction guardrail installation device, by moving the telescopic rod to the right, the telescopic rod drives the slider to move, and the slider compresses the spring, thereby facilitating the adjustment of the distance between the two sets of bases according to guardrails of different lengths. 2. This highway construction guardrail installation device uses a sliding block with a corresponding mounting groove on it to a specific mounting groove on a telescopic cylinder, where multiple sets of mounting grooves are evenly spaced. Tightening the mounting bolts then limits the sliding block's position, effectively preventing deviations in the spacing between the two sets. 3. In this highway construction guardrail installation device, the rotating shaft drives the sleeve to rotate via a transmission assembly. Since the threaded rod is slidably connected to the guide rod via a limiting rod and is threadedly connected to the sleeve, the sleeve drives the threaded rod to move upwards under the limiting position of the guide rod, thereby adjusting the height of the guardrail.

[0005] Although the two guardrail robots mentioned above have achieved many functions, many steps still require manual operation, and more than three people are still needed to operate them. Their integration and intelligence levels are low, their loading capacity is small, and their efficiency is low. Summary of the Invention
