Abstract
Description
Technical Field
[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a grouting device for road and bridge construction. Background Technology
[0002] Roads or bridges will be damaged after being driven by vehicles for a long time or eroded by rainwater. Road administration departments need to repair the damaged roads or bridges in a timely manner. Repair is usually done by filling cracks or potholes with concrete or asphalt, which requires the use of grouting devices. However, the existing grouting devices have relatively simple structures and limited functions.
[0003] Chinese Patent No. CN222525200U discloses a grouting device for road and bridge construction. This utility model uses a drive shaft and cam set in a storage tank to push a filter plate to move up and down in an orderly manner. This not only enhances the fluidity of the slurry, but also effectively screens and filters impurities or particles in the slurry, reducing the potential clogging risk of impurities or particles in the slurry to the grouting device. This makes the grouting device for road and bridge construction more practical and convenient to use.
[0004] However, the device still has shortcomings: changing the position or orientation of the discharge pipe outlet requires adjusting the angle of the vehicle body, which is laborious. Furthermore, before using the device for grouting, it is necessary to clean the impurities inside the cracks or potholes with equipment, which is time-consuming, laborious, and results in low road repair efficiency.

The HMI provides users with an intuitive and user-friendly interface, allowing them to easily issue various commands by touching the screen. A camera 28 is installed on the bracket 3, and while the disc 10 drives the discharge pipe 14 to rotate at a certain angle, the drive component D drives the blow pipe 20 to rotate in the opposite direction around the axis of the discharge pipe 14 by the same amount of angle.
[0026] In this embodiment, the vehicle body is driven by four independently driven but interconnected Mecanum wheels 2, enabling rapid forward, backward, lateral, and turning operations. During construction, concrete (or asphalt) is first received at the outlet of the mixer truck and placed into the storage tank 4. Then, motor A is started, driving the mixing paddle 8 to rotate at a low speed to ensure that the concrete does not dry out and to maintain the uniformity of the concrete. When it reaches the crack (or pothole) that needs to be repaired, motor C is started, driving the disc 10 to rotate (taking a 90-degree clockwise rotation as an example), thereby moving the discharge port of the discharge pipe 14 to above the edge of the crack opening. At the same time, motor D and blower 27 are started, with motor D driving the ring 19 to rotate around the discharge pipe. The shaft of the material pipe 14 rotates 90 degrees counterclockwise, causing the blower pipe 20 to move in the direction that the discharge pipe 14 is about to advance. The blower 27 operates, sending air into the annular groove of the air guide ring 24 through the air outlet pipe. The airflow enters the guide pipe B26 through the annular groove, and then enters the blower pipe 20 along the hollow shaft 15, the adapter B22 and the guide pipe A21. The high-speed air jet blows away the leaves, twigs and other impurities in the crack that are in the direction that the discharge pipe 14 is about to advance. At this time, the solenoid valve 51 is opened to start feeding. The mortar enters the guide pipe 11 through the feeding pipe 5 and the feed pipe 12. The motor B is started, and the motor B drives the hollow shaft 15 and the spiral plate 16 to rotate, thereby guiding the mortar (or concrete) into the crack along the discharge pipe 14.
[0027] Example 2
[0028] like Figure 1 As shown, the road and bridge construction grouting device proposed in this utility model, compared with the first embodiment, has an air pump 7 installed on the bucket cover. The input end of the air pump 7 is connected to the outside, and the output end of the air pump 7 is connected to the inside of the storage bucket 4.
[0029] In this embodiment, since the device discharges material by gravity from high to low, in order to improve the discharge efficiency, the sealing cover 61 is closed during discharge, and then air is pumped into the storage tank 4 by the air pump 7 to increase the air pressure in the storage tank 4 and accelerate the material entering the discharge pipe 5.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
