Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of highway engineering maintenance equipment, in particular to a highway engineering maintenance operation device. BACKGROUND

[0002] As an important infrastructure for transportation, highways are subjected to vehicle load, natural environmental erosion (such as sunlight, rain, and freezing) for a long time, and are prone to diseases such as pavement cracking, aging, and sanding. If not maintained in time, the diseases will intensify, affecting traffic safety and the service life of the highway.

[0003] However, in actual application, the mixing, stirring, and spraying of the maintenance liquid in highway maintenance operations rely on independent equipment. After stirring, the maintenance liquid needs to be transferred to the spraying device through a transfer device, which is complicated and prone to stratified precipitation of the maintenance liquid during the transfer process, reducing the maintenance effect. Meanwhile, the stirring equipment mostly uses single rotation, which causes uneven mixing of the components of the maintenance liquid, further affecting the quality of pavement maintenance. Pavement cleaning, maintenance liquid spraying, and maintenance liquid smoothing are scattered operations that require multiple equipment or manual assistance, which is inefficient and prone to uneven smearing during manual smoothing, resulting in inconsistent pavement absorption of the maintenance liquid. The existing spraying device has poor flexibility in adjusting the spraying width, mostly fixed width or only limited folding adjustment, which cannot adapt to highways of different widths, limiting the coverage range of a single operation and increasing the maintenance time cost, which is not conducive to actual application and operation.

[0040] In use, the second driving motor 26 at the top of the stirring tank 2 is turned on, and the output shaft of the second driving motor 26 drives the rotating frame 5 to rotate on the inner wall of the stirring tank 2; when the rotating frame 5 rotates, the first gear 6 at the top is clamped in the tooth groove 4 of the inner wall of the stirring tank 2 and rotates synchronously, and the stirring rod 7 at the bottom of the rotating frame 5 also rotates synchronously, so that the maintenance liquid in the tank is stirred; the stirring rod 7 also drives the connecting frame 8 at the bottom of the stirring tank 2 to rotate, and the shaft of the connecting frame 8 drives the rotating disc 9 and the cleaning brush 10 at the bottom of the vehicle frame 1 to rotate, so that the maintenance liquid is evenly stirred, and the components for road operation are also powered.

[0041] The driving motor in the vehicle frame 1 is turned on, and the motor shaft drives one of the second gears 12 to rotate, because the two second gears 12 are engaged together, so they rotate synchronously, and then the connecting rod 13 outside the shaft of the first gear 6 adjusts the angle, and the extension direction of the connecting pipe 16 is adjusted; then the first driving motor 25 outside the second fixed plate 19 is turned on, and the motor shaft drives the rotating pipe 20 to rotate between the two second fixed plates 19, and the sliding groove 23 outside the rotating pipe 20 drives the sliding block 24 on the linkage block 22 to slide, so that the linkage block 22 and the threaded rod 21 rotate synchronously; because the threaded rod 21 is screwed on the second fixed plate 19, when it rotates, it moves along the shaft and pushes the extension rod 17 to slide in the connecting pipe 16, so that the extension length is adjusted.
