Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a grouting device for bridge construction. Background Art

[0002] Road bridges are generally composed of several major parts, such as roadbed, pavement, bridge, tunnel engineering and traffic engineering facilities. Existing bridge construction requires the use of concrete grouting, and grouting requires the use of large grouting vehicles for operation. However, large grouting vehicles are suitable for large-area pouring, but not for small-area pouring. If forced to operate, concrete will spill to the outside of the small-area pouring area, which not only causes material waste but also makes it difficult to clean. Patent documents have now been made to improve this.

[0003] For example, Chinese patent CN220550560U discloses a grouting device for road and bridge construction, comprising a mixing box, wherein the upper end of the mixing box is fixedly connected to a motor, the lower end of the motor's rotating shaft is fixedly connected to a plurality of stirring blades at equal intervals, the middle portion of the lower end of the mixing box is fixedly connected to the input end of a discharge valve, the output end of the discharge valve is fixedly connected to one end of a feed pipe, the other end of the feed pipe is fixedly connected to the input end of a feed pump, the output end of the feed pump is fixedly connected to one end of a connecting pipe, the other end of the connecting pipe is fixedly connected to the left end of a connector, and the right end of the connector is fixedly connected to a grouting pipe. In this solution, the stirring blades are driven by a motor to stir the concrete, and after the grouting concrete is produced, the discharge valve is opened to cause the feed pump to transport the concrete through the feed pipe and the connecting pipe to the grouting pipe for grouting, thereby increasing the concrete output efficiency during grouting and working efficiency.

[0004] Although the equipment in the above documents can move materials to a designated location for mixing and pouring in a small area to avoid spillage during pouring, it still has obvious defects in actual use, such as: In existing construction sites, concrete is generally delivered directly from concrete trucks. However, the equipment described in the above documents requires multiple raw materials to be put into a mixing box for re-production before pouring. Moreover, after the concrete is consumed, the equipment needs to be pushed back to its original position and the materials need to be placed again for mixing, which reduces the pouring efficiency and is too cumbersome to use. Therefore, a grouting device for bridge construction that can improve grouting efficiency and is easy to use is now designed to solve this type of defect. Summary of the Invention

[0014] The present invention provides a grouting device for bridge construction. Compared with existing technologies, it has the following advantages: (1) The grouting device for bridge construction uses a grouting cleaning mechanism and a material storage and mixing mechanism in combination.

Then, the arc-shaped top plate will squeeze the lifting plate to drive the arc-shaped sealing plate and the sleeve tube to connect with the solenoid valve tube, so that the U-shaped load-bearing frame can be quickly installed and disassembled with the U-shaped connecting groove without the need for tedious installation operations. In addition, the arc-shaped sealing plate can effectively prevent concrete leakage and improve the sealing performance.

[0016] (3) The grouting device for bridge construction is installed with a transverse pipe and a high-pressure nozzle on the surface of the load-bearing base plate, and is used in conjunction with a first button. The arrangement of these structures can first make the arc-shaped sealing plate descend and separate from the solenoid valve tube after the transverse pressure plate is moved to the left and reset, and then the transverse pressure plate will press the first button, at which time the water pump will be started, allowing the high-pressure nozzle to spray water on the arc-shaped sealing plate, thereby flushing the top of the arc-shaped sealing plate to ensure that it can fit more closely with the bottom of the round barrel in the subsequent contact.

[0021] When in use, the material storage and mixing mechanism 2 is provided with two groups, and concrete is injected into the interior of the round barrel 204 through the injection frame 205 at the same time. Since the electromagnetic valve tube 206 is in a closed state at this time, concrete will not leak from the electromagnetic valve tube 206. After the injection is completed, one of the round barrels 204 is pushed by the second universal wheel 202, so that the U-shaped load-bearing frame 201 is inserted into the inner side of the U-shaped connecting groove 102 from the rear. After the U-shaped load-bearing frame 201 is completely docked with the U-shaped connecting groove 102, the electromagnetic valve tube 206 is perpendicular to the sleeve tube 119.

[0023] After the concrete inside the round barrel 204 is extracted, the cylinder 106 is started to pull the horizontal pressure plate 107 and the arc top plate 108 to the left. After the arc top plate 108 moves to the left, it no longer squeezes the lifting plate 121. At this time, the arc sealing plate 118 and the sleeve tube 119 descend in the limit of the vertical guide rod 117. When the horizontal pressure plate 107 moves to the leftmost, the two first buttons 109 are pressed. After the two first buttons 109 are pressed, the solenoid valve tube 206 is first closed, and then the water pump 112 is started. At this time, the water pump 112 uses the infusion tube 11 The water inside the water tank 114 is pumped out, and the high-pressure nozzle 111 is used to spray water toward the arc-shaped sealing plate 118 to clean the top of the arc-shaped sealing plate 118. After the arc-shaped top plate 108 is separated from the first positioning port 105, the U-shaped load-bearing frame 201 is pulled out from the inside of the U-shaped connecting groove 102. Then, another round barrel 204 filled with concrete is inserted into the U-shaped connecting groove 102 using the U-shaped load-bearing frame 201, and concrete is poured again. At the same time, the other round barrel 204 that has been replaced continues to be loaded with concrete.
