Description

Technical Field

[0001] The utility model relates to the technical field of caulking, in particular to a caulking device for road and bridge construction. Background Technique

[0002] After the construction of roads and bridges, cracks often occur on the road surface after vehicles drive back and forth, and the cracks need to be caulked and repaired in time.

[0003] At present, most of the caulking devices for road and bridge construction use the method of high-pressure grouting to input the repair liquid into the gap to achieve repair. However, the current repair devices all rely on the nozzle to inject into the gap. However, the gap space is narrow, and it is difficult to fully fill only by the self-flow of the repair liquid, and voids are likely to appear, affecting the repair effect. Summary of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects.

[0005] For this reason, an object of the utility model is to provide a caulking device for road and bridge construction to solve the problems mentioned in the background technique and overcome the deficiencies existing in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the utility model provides a caulking device for road and bridge construction, including a grouting pipe. The bottom of the grouting pipe is fixedly connected with a caulking nozzle. The bottom of the outer wall of the grouting pipe is fixedly connected with a spring baffle. The bottom of the outer wall of the grouting pipe is slidably connected with a guiding sleeve. The bottom end of the guiding sleeve is fixedly connected with a pushing plate. The middle of the bottom end of the pushing plate is fixedly connected with a cover cylinder. The bottom of the cover cylinder is fixedly connected with a vibrating plate. The cover cylinder covers the outside of the caulking nozzle. The middle parts of both sides of the outer wall of the cover cylinder are fixedly connected with vibration components. The top of the guiding sleeve is fixedly connected with a spring top plate. The bottom of the outer wall of the grouting pipe is sleeved with a supporting spring. The supporting spring is between the top surface of the spring top plate and the bottom surface of the spring baffle. The spring top plate presses the vibrating plate against the ground under the push of the supporting spring.

[0007] Preferably, according to any of the above solutions, a feeding pipe joint is fixedly connected to the center of the top end of the grouting pipe, and the inner wall of the cover cylinder fits with the outer wall of the caulking nozzle.

[0008] The technical effect achieved by adopting the above solution is that the stability of the downward vibration of the cover cylinder can be improved by the fit between the inner wall of the cover cylinder and the outer wall of the caulking nozzle, and it is not easy to deflect.

[0009] Preferably, according to any of the above solutions, the vibration assembly includes a dual-output motor. Eccentric disks are fixedly connected to the two output ends of the dual-output motor. Protective covers are fixedly connected to both side surfaces of the dual-output ends of the dual-output motor. The protective covers cover the outside of the eccentric disks. By covering the eccentric disks with the protective covers, it is possible to prevent the eccentric disks from being damaged or endangered by collisions during high-speed rotation.

[0010] The technical effect achieved by adopting the above solution is that the eccentric disks are driven to rotate by the dual-output motor to generate eccentric forces, and vertical vibrations are generated under the guidance of the guide sleeves.

[0011] Preferably, according to any of the above solutions, a counterweight block is fixedly connected to the top surface of the push plate, and the intersection center of the diagonal of the counterweight block corresponds to the center of the circle of the grouting pipe.

[0012] The technical effect achieved by adopting the above solution is that the kinetic energy of the downward impact can be increased through the counterweight block to improve the vibration effect, and the uniform distribution of the counterweight block makes the impact force more uniform.

[0013] Preferably, according to any of the above solutions, the two vibration assemblies are symmetrically arranged left and right, the two vibration assemblies are synchronously driven, and the length of the cover cylinder is adapted to the length of the caulking nozzle.

[0014] The technical effect achieved by adopting the above solution is that the bottom of the cover cylinder can be pressed against the outer surface of the caulking nozzle that tightens the gap.

[0015] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0016] For the caulking device for road and bridge construction, after connecting the grouting pipeline through the material conveying pipe joint, the caulking nozzle is aligned with the gap and pressed tightly. At this time, the vibrating plate will be pressed against the edge of the gap. Then, the gap is grouted through the caulking nozzle. At the same time, the vibration assembly is started to drive the guide sleeve to vibrate up and down. The vibration is transmitted to the road and bridge surface through the vibrating plate, causing the repaired gap to vibrate, so that the filler flows into the gap more stably under vibration and bubbles are discharged, making the filling material fill the gap more tightly and solidly.
