Description

Technical Field

[0001] This utility model relates to the technical field of maintenance emergency devices, specifically a highway maintenance emergency device. Background Technology

[0002] Highways refer to public roads between cities, between urban and rural areas, and between rural areas that are open to automobiles and have been inspected and approved by the transportation authorities. This includes highways that have already been built and approved by the transportation authorities. Highway maintenance refers to a series of activities involving the regular inspection, upkeep, repair, and improvement of highway systems that have been built and put into use. After a highway is built and opened to traffic, its quality will gradually decrease due to wear and impact from wheels, erosion and weathering from natural forces such as rainstorms, floods, wind and sand, snow, sun, and ice melting, as well as human damage and certain defects left over from the construction.

[0003] For example, the emergency road maintenance device disclosed in the authorization announcement number CN214460070U includes a salt storage tank and a fixed cavity. The inner top wall of the salt storage tank is provided with a No. 1 guide plate, and a No. 1 motor is installed above the salt storage tank. The output end of the No. 1 motor is connected to a connecting shaft, and the bottom end of the connecting shaft is connected to a movable frame. One side of the movable frame is connected to a telescopic rod, and the side of the movable frame away from the telescopic rod is connected to a push rod. One end of the push rod is connected to a drain needle.

[0004] Although it achieves the following during use: starting motor 1, the output of motor 1 drives the connecting shaft to rotate via a coupling. The bottom of the connecting shaft is connected to the gear in the middle of the movable frame. The gear interacts with the two rows of racks on the inner side of the movable frame, causing the movable frame to move back and forth under the restriction of the telescopic rod. This drives the push rod to push the accumulated salt. The unblocking needle at one end of the push rod helps to unclog the blocked salt blocks and prevent blockage. During use, starting motor 2, the output of motor 2 drives the belt to rotate, which in turn drives the rotating rod to rotate under the action of the inner shaft, causing the four push plates to rotate and push the salt on the conveyor belt. The inner rod, outer rod, movable block and spring form a buffer structure that can buffer and protect the push plates.

[0005] However, this does not solve the problem that existing maintenance emergency devices are generally not conducive to convenient multi-level adjustment of the angle and extension of the length for pouring, which affects the pouring range, the efficiency of pouring, and the ease with which the device can be easily rotated to warn personnel, thus affecting the warning effect and the conspicuousness of the warning.

The threaded blocks drive the telescopic column, connecting plate, rotating shaft, support arm, beam arm, telescopic rod, connecting frame, and flexible pipe to move to a specified height for pouring. When it is necessary to adjust the rotation angle for pouring, the servo motor drives the pinion to rotate, and the large gear drives the rotating shaft, support arm, beam arm, telescopic rod, connecting frame, and flexible pipe to rotate a certain angle for pouring.

[0020] The motor drives the fifth shaft to rotate, which in turn drives the rotating disk to rotate. The rotating disk then drives the support shaft to rotate. Under the limit of the third shaft, the support shaft drives the connecting arm and the sector rack to reciprocate around the third shaft. The sector rack drives the first rack and the warning plate to reciprocate, thus realizing the convenient reciprocating rotation of the maintenance emergency device to warn personnel, increasing the warning effect and improving the visibility of the maintenance emergency device.

The first electric push rod 17 drives the first shaft 20 to move, and the first shaft 20 drives the beam arm 19, telescopic rod 22, and flexible pipe 28 to rotate around the rotating shaft 18. The second electric push rod 21 drives the telescopic rod 22 to extend, and the telescopic rod 22 drives the connecting frame 27 and flexible pipe 28 to extend a certain distance. The third electric push rod 23 drives the second shaft 24 to move, and the second shaft 24 drives the connecting frame 27 and flexible pipe 28 to rotate around the fourth shaft 26 to adjust their positions. The stepper motor 29 drives the threaded rod 30 to rotate, and the threaded rod 30 drives two sets of threaded blocks 31 to move up and down. The threaded blocks 31 drive the telescopic column 7. The connecting plate 8, rotating shaft 13, support arm 15, beam arm 19, telescopic rod 22, connecting frame 27, and flexible pipe 28 are moved to a specified height for pouring. When the rotation angle needs to be adjusted for pouring, the servo motor 11 drives the pinion 12 to rotate, and the large gear 14 drives the rotating shaft 13, support arm 15, beam arm 19, telescopic rod 22, connecting frame 27, and flexible pipe 28 to rotate at a certain angle for pouring. The power motor 32 drives the fifth shaft 33 to rotate, the fifth shaft 33 drives the rotating disk 39 to rotate, and the rotating disk 39 drives the support shaft 16 to rotate.
