Description

Technical Field

[0001] The utility model relates to a crack filling device, in particular to a highway maintenance crack filling device, belonging to the technical field of highway maintenance equipment. Background Art

[0002] Road maintenance refers to the work performed to keep the highway in good condition, prevent its quality of use from deteriorating, and provide good services to highway users. After the highway is built and opened to traffic, it is subjected to wear and impact from wheels, erosion and weathering from natural forces such as rainstorms, floods, sandstorms, ice and snow, sunlight, ice melt, as well as human destruction and certain defects left over from construction. The cracks in the highway or the gaps after repair need to be grouted, and grouting requires the use of a grouting device.

[0003] A road caulking maintenance device for municipal engineering disclosed in the Chinese patent application publication CN214194075U includes a base plate, a roller, a cart handle, a mixing box, a box door, a motor, a rotating shaft, a mounting plate, a stirring paddle assembly, a feeding pipe, a delivery pump, a material extraction pipe and a discharge pipe. Rollers are fixedly installed at the four corners of the bottom of the base plate, a cart handle is fixedly connected to the left side of the base plate, a mixing box is fixedly connected to the left side of the top of the base plate, a box door is provided on the front side of the mixing box, and a motor is fixedly connected at the midpoint of the top of the mixing box. The utility model cooperates with the base plate, the roller, the cart handle, the mixing box, the box door, the motor, the rotating shaft, the mounting plate, the stirring paddle assembly, the feeding pipe, the delivery pump, the material extraction pipe and the discharge pipe to facilitate the cleaning of the stirring paddle. The stirring paddle can be easily disassembled during cleaning, so that the user can clean the stirring paddle in an all-round manner, which brings great convenience to the user.

[0004] The above-mentioned device achieves the effect of facilitating the user to clean the stirring paddle by providing an easy-to-disassemble stirring paddle. However, the construction temperature of the sealant is relatively high. For example, the construction temperature of the asphalt sealant should be around 150 degrees. After the device completes the ground seam filling, the temperature of the stirring paddle is relatively high. The staff needs to wait for the stirring paddle to cool down before taking it out, which causes the sealant to solidify on the surface of the stirring paddle, increasing the difficulty of cleaning the stirring paddle. In addition, when filling the ground seams, the sealant may overflow from the gaps, reducing the aesthetics of the road surface. Summary of the invention

[0005] The utility model proposes a highway maintenance grouting device to solve the problem in the prior art that the stirring paddle needs to be cooled before it can be taken out, thereby causing the grout to solidify on the surface of the stirring paddle, increasing the difficulty of cleaning the stirring paddle, and the grout may overflow from the ground cracks, reducing the aesthetics of the road surface.

[0006] The utility model is implemented through the following technical scheme: a highway maintenance grouting device, comprising a base plate, a stirring mechanism capable of stirring asphalt is provided on the upper part of the base plate, the stirring mechanism comprises a stirring tank, a cover plate is provided above the stirring tank, a lifting mechanism capable of lifting the height of the cover plate is provided on the upper part of the base plate, the lifting mechanism comprises two lifting frames, each of the lifting frames is fixed to the upper surface of the base plate, the bottom surface of each of the lifting frames is rotatably connected to a threaded rod through a rotating shaft, the outer surface of each of the threaded rods is threadedly connected to a lifting block, two support rods are fixed to the upper surface of each of the support rods, the upper end of each of the support rods is fixed to the cover plate, a grouting assembly is provided on the outside of the base plate, the grouting assembly comprises a feed pump, and the input end of the feed pump is connected to the stirring tank through a hose.

[0009] Specifically, a bevel gear 2 is fixed to the bottom end of each threaded rod, the outer surface of each threaded rod is rotatably connected to the inside of the base plate, and each bevel gear 1 is meshed with the corresponding bevel gear 2. Bevel gear 1 can drive bevel gear 2 to rotate, thereby driving the two threaded rods to rotate synchronously.

[0010] Specifically, a stirring motor is fixed on the upper surface of the cover plate, and a stirring paddle is fixed on the output end of the stirring motor. The stirring paddle is driven to rotate by the stirring motor to stir the caulking agent. The cover plate can support and fix the stirring motor.

[0011] Specifically, a fixing plate is fixed on the outer surface of the base plate, and a caulking pipe is slidably connected inside the fixing plate.

A contraction spring is sleeved on the outer surface of each pressure rod. An L-shaped smear plate is provided under the support plate, and the bottom ends of the two pressure rods are fixed to the L-shaped smear plate. The L-shaped smear plate can smooth out the overflowed caulking agent, and the L-shaped smear plate can move up and down with the changes in the terrain. Under the action of the elastic force of the contraction spring, the L-shaped smear plate can always fit the ground.

[0013] Specifically, a handle is fixed on the outer surface of the base plate, and universal wheels distributed at equal distances are fixedly connected to the lower surface of the base plate. The handle and the universal wheels are provided to facilitate the user to move the device.

During the grouting operation, the support plate can drive the pressure rod to move, so that the pressure rod drives the L-shaped trowel to move. Under the action of the elastic force of the contraction spring, it can ensure that the L-shaped trowel can always fit the ground, so that the L-shaped trowel can smooth the overflowed filler, thereby making the grouting operation of the device more beautiful.
