Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a grouting device for highway bridge construction. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as buildings, workshops and other service facilities used for construction, maintenance and monitoring. Sometimes, maintenance and grouting are required on highways.

[0003] The "Grouting Device for Highway Bridge Construction" described in patent application number "202520128640.4" includes a mortar cylinder with a fixed pipe below it. A connecting pipe is fixedly connected between the mortar cylinder and the fixed pipe. The fixed pipe has a mortar feeding mechanism inside, which can adjust the mortar feeding distance as needed. By fixing the telescopic end of a second electric telescopic rod to one side inside the connecting pipe, the second electric telescopic rod can respond quickly when the nozzle position needs to be adjusted, driving the extension pipe to move flexibly to adapt to different grouting points, reducing the number of equipment handling and adjustment times, improving flexibility and accuracy, and saving construction time. The threaded conveying blade uses the propulsive force of the spiral structure to grout efficiently, overcoming the viscous resistance of the mortar, making the mortar advance continuously and at a uniform speed, increasing the grouting speed, ensuring density, and enhancing the stability and durability of the engineering structure.

[0004] However, the applicant believes that the device has the following problems in use: the mortar is stirred by the motor driving the rotating shaft and the stirring blade, but the mortar adhering to the rotating shaft and the stirring blade cannot be cleaned by the staff, which easily increases the power consumption of the motor. In addition, the mortar is transported by the rotating rod and the threaded conveyor blade, and the mortar easily hardens and adheres to the threaded conveyor blade. As the mortar continues to accumulate, it is easy to cause blockage of the fixed pipe. Utility Model Content

[0005] The purpose of this utility model is to provide a grouting device for highway bridge construction, which solves the problems of inconvenience for workers to clean the mortar on the mixing rod, which increases motor power consumption and the inconvenience for workers to clean the mortar on the threaded conveying rod, which easily leads to blockage of the fixing pipe.

[0006] To achieve the above objectives, a grouting device for highway bridge construction is provided, comprising: a mounting base, a grouting barrel fixedly connected to the upper surface of the mounting base, a mounting plate fitted onto the upper surface of the grouting barrel, four first fixing bolts inserted into the upper surface of the mounting plate, the lower ends of the four first fixing bolts being threaded into the interior of the grouting barrel, a rotating disk rotatably connected to the upper surface of the mounting plate, a stirring rod fixedly connected to the lower surface of the rotating disk, a mounting frame provided on the upper surface of the grouting barrel, two second fixing bolts inserted into the upper surface of the mounting frame, the lower ends of the two second fixing bolts being threaded into the interior of the grouting barrel, a first motor fixedly connected to the upper surface of the mounting frame, an insertion rod fixedly connected to the output end of the first motor, the lower end of the insertion rod being inserted into the interior of the rotating disk, allowing workers to remove the stirring rod for easy cleaning of residual mortar, preventing mortar from drying and adhering, and reducing the load on the first motor;

[0007] A fixing tube is provided at the lower part of the mounting base. A sealing cover is fitted onto the upper surface of the fixing tube. An insert plate is fixedly connected to one side of the sealing cover. The insert plate is inserted into the interior of the fixing tube. A sealing gasket is installed between the sealing cover and the fixing tube. A connecting ring is fitted onto the side of the sealing cover and the fixing tube. Two first fixing screws are inserted into the side of the connecting ring. The two first fixing screws are threadedly connected to the interior of the fixing tube and the interior of the sealing cover, respectively. A second motor is fixedly connected to one end of the fixing tube. A threaded conveying rod is inserted into the power transmission end of the second motor. A second fixing screw is inserted into the output end of the second motor. The upper end of the second fixing screw is threadedly connected to the end of the threaded conveying rod near the second motor. An isolation plate is fixedly connected to the interior of the fixing tube. The interior of the isolation plate is rotatably connected to the exterior of the threaded conveying rod. Workers can remove the sealing cover and separate the threaded conveying rod from the second motor, making it convenient for workers to clean the mortar on the threaded conveying rod. This prevents the mortar on the threaded conveying rod from drying and accumulating, and prevents the fixing tube from becoming blocked.

[0008] According to the grouting device for highway bridge construction, the lower surface of the grouting bucket is connected to the discharge port, and the lower end of the discharge port is connected to the upper surface of the fixed pipe to facilitate mortar delivery.

[0012] According to the grouting device for highway bridge construction, the cross-section of the insertion rod is square to facilitate transmission through the insertion rod.

[0013] According to the grouting device for highway bridge construction, the mixing rod is installed inside the grouting tank, and the diameter of the mixing rod is smaller than the diameter of the mounting plate to facilitate the removal of the mixing rod.

The auxiliary steel strip can provide auxiliary support for the fixed pipe, which is beneficial to the stability of the fixed pipe.

[0015] The above-mentioned solution has the following beneficial effects:

[0016] 1. By removing the second fixing bolt, it is convenient for workers to disassemble the first motor, separate the plug rod from the rotating plate, and remove the first fixing bolt to facilitate the disassembly of the installation plate and cleaning of residual mortar on the mixing rod, preventing mortar from drying and adhering, which helps to reduce the load on the first motor.

[0017] 2. By removing the first fixing screw, it is convenient for the staff to remove the connecting ring. By removing the connecting ring, it is convenient to disconnect the connection between the sealing cover and the fixing tube.
