Description

Technical Field

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

[0002] Roads and bridges generally refer to structures erected on rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. They are generally composed of several major parts, such as roadbed, pavement, bridges, tunnel projects, and traffic engineering facilities. When repairing and constructing roads and bridges, grouting devices are required to inject cement and concrete slurry into designated locations.

[0003] A Chinese patent with a search announcement number of CN117005312A discloses a grouting device for road and bridge construction, including a workbench, two mounting plates are installed on the top of the workbench, and a mixing barrel is movably installed on the opposite side of the two mounting plates; it also includes a first driving component for driving the mixing barrel to rotate. When the invention is used, the feed pump conveys the mixed slurry in the mixing barrel to the fixed conduit, and the slurry in the fixed conduit flows into the transition shell through the extension conduit and the perforation, and finally grouting is achieved through the grouting pipe. At the same time, the first driving component drives the mixing barrel to rotate, driving the spaced jacking protrusions to reciprocately push and press the top of the extension rod, so that the mounting side wings, the mounting frame, the extension conduit and the grouting pipe are reciprocated and lifted and shaken under the pushing action of the jacking protrusions and the elastic action of the spring, that is, while grouting, the grouting pipe stirs the slurry injected into the gap to ensure uniform grouting.

[0004] However, the above invention has the following disadvantages: Although the above invention can achieve the effect of uniform grouting, during grouting, in order to ensure that the concrete can be well coagulated between the bridge, the inside of the grouting position needs to be cleaned. If there is dust inside the grouting position, it will affect the grouting effect. In order to ensure the grouting effect, it needs to be cleaned before grouting, which is more troublesome.

[0016] The present invention provides a grouting device for road and bridge construction through improvement, which has the following improvements and advantages compared with the prior art: First, the present invention arranges a transmission mechanism and a blowing mechanism. When the device is moving for grouting, the moving wheel will drive the wheel axle to rotate, and the wheel axle will then drive the first gear to rotate. The first gear is meshed with the second gear, and then can drive the second gear to rotate. The second gear then drives the fan blades to rotate through the transmission shaft. The rotation of the fan blades can generate wind pressure inside the mounting frame, and air is taken into the interior of the mounting frame through the air inlet pipe. Then, air can be blown through the blowing pipe. The position of the blowing pipe corresponds to the position of the discharge pipe. The blowing of the blowing pipe can blow and clean the interior that needs grouting, thereby achieving the effect of automatically blowing and cleaning the dust inside the grouting position during grouting, thereby improving the grouting effect.

[0017] Second: In the present invention, when blowing, the transmission shaft will also drive the extrusion wheel to rotate, and the rotation of the extrusion wheel will squeeze the connecting rod. Two abutments are fixedly installed inside the air inlet pipe, and a reset spring is connected between the abutment block and the filter. The filter is movably installed inside the air inlet pipe through the abutment block and the reset spring, so that when the extrusion wheel squeezes the connecting rod, the filter will move downward and then reset, so that the filter can vibrate inside the air inlet pipe, thereby avoiding the situation where the filter is blocked by dust due to long-term use.

[0018] Third: In the present invention, the first motor can be started, and the first motor can drive the reciprocating screw to rotate. The rotation of the reciprocating screw can drive the extrusion block to move between the two movable plates through the reciprocating shaft sleeve, and the two movable plates can be squeezed, so that the movable plates are flipped inside the blowing pipe, and then the size between the two movable plates can be changed, thereby adjusting the intensity of blowing.

[0019] Fourthly, in the present invention, the electric push rod can be started after the mixing is completed, and the electric push rod can drive the pulley seat and the pulley to move upward. When the pulley moves upward, it will squeeze the mixing barrel, and the mixing barrel will drive the mounting seat to flip with the rotating shaft as the base point. The slider will also move inside the slide groove with the movable seat. The movement of the slider can limit the flipping of the mixing barrel. At this time, the concrete inside the mixing barrel will flow toward the flipped end of the mixing barrel, and then it can be discharged from the inside of the mixing barrel through the discharge pipe, which improves the discharge effect, reduces the residual concrete inside the mixing barrel, and makes the discharge more thorough.

[0020] Fifth: In the present invention, the adjusting shaft can be rotated when unloading, and the adjusting shaft is threadedly connected to the transmission block, so that the transmission block will move downward inside the adjusting groove, and then drive the movable tube to move downward, thereby achieving the effect of arbitrarily adjusting the unloading height.
