Description

Technical Field

[0001] This utility model relates to the field of road crack sealing technology, specifically to a road asphalt crack sealing device. Background Technology

[0002] In the routine maintenance of infrastructure such as highways, urban roads, and airport runways, asphalt pavement crack repair is an important and frequent task. With the increase in traffic load and changes in climate, asphalt pavements are prone to longitudinal, transverse, or network cracks. If not treated in time, rainwater seeps into the base layer, causing the subgrade to soften, the load-bearing capacity to decrease, and thus accelerating pavement damage, seriously affecting the service life of the road and driving safety. Currently, asphalt crack sealing equipment generally includes an asphalt bucket and a crack sealing pipe. During use, asphalt from the asphalt bucket is continuously delivered to the crack sealing pipe, and then injected into the crack through the crack sealing pipe. However, existing crack sealing pipes generally have a fixed structure and length, using a long metal or plastic rigid pipe connected to a conveying hose, with an extrusion nozzle at the front end. This type of pipe cannot be flexibly adjusted according to the construction space, and is difficult to operate, especially in narrow areas (such as next to curbs or around manhole covers). Furthermore, it is not easy to maintain when clogged. Therefore, a road asphalt crack sealing device that is easy to maintain is needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a road asphalt crack sealing device that is easy to maintain.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a road asphalt crack sealing device, including a crack sealing pipe, an extrusion head and a material conveying pipe; The grouting pipe includes connecting pipes, and multiple connecting pipes are provided. After the connecting pipes are arranged in sequence, they are connected by a positioning mechanism. The extrusion head is located at the end of the sealing tube and is connected to the connecting tube at the very end via a positioning mechanism; The other end of the material delivery pipe is connected to the crack filling pipe via a positioning mechanism.

[0005] As an improvement, the delivery pipe includes a delivery hose and a delivery sleeve. One end of the delivery hose is connected to the crack filling liquid, and the other end is connected to the delivery sleeve. The delivery sleeve is connected to the other end of the crack filling pipe through a positioning mechanism.

[0006] As an improvement, the positioning mechanism includes an externally threaded tube and an internally threaded tube; One end of the connecting pipe has an external threaded pipe fixed on its outer wall, and the other end has an internal threaded pipe that matches the external threaded pipe. After the connecting pipes are arranged in sequence, the internal threaded pipes and external threaded pipes of adjacent connecting pipes are threaded together. The extrusion head has an external threaded pipe, and the material conveying sleeve has an internal threaded pipe.

[0007] As an improvement, a sealing ring is also included. The sealing ring is placed around the external threaded pipe and closely adheres to the outer wall of the end of the connecting pipe. After the internal threaded pipe and the external threaded pipe of the adjacent connecting pipe are threaded together, the sealing ring is closely adhered to the outer wall of the two connecting pipes. The sealing ring is set at the root of the external threaded pipe. When the two connecting pipes are tightened, the sealing ring is compressed and closely adheres to the outer wall of the two pipes, forming an annular sealing band to prevent high-temperature asphalt from seeping out from the thread gap and to ensure construction safety.

[0008] As an improvement, the positioning mechanism also includes a locking ring; Locking rings are welded and fixed to the outer walls of both ends of each connecting pipe. After the internal threaded pipe and the external threaded pipe of adjacent connecting pipes are connected by thread, the adjacent locking rings are tightly attached. After the locking bolt passes through the preset through hole on the locking ring, it is tightened by the nut.

[0009] As an improvement, each connecting pipe is equipped with an auxiliary handle, and an anti-slip pad is attached to the auxiliary handle. Each connecting pipe section is equipped with an auxiliary handle with an anti-slip pad, which facilitates multi-person collaborative operation or single-person adjustment of direction.

[0010] The advantages of this utility model compared with the prior art are as follows: 1. The crack sealing pipe is modularly assembled from multiple connecting pipes. The number of pipe sections can be freely increased or decreased according to the length of the crack and the spatial layout on site. It is suitable for various working conditions such as straight cracks, curved cracks, and narrow cracks. 2. The connection is firm and reliable, preventing loosening. It adopts an initial connection of "external threaded pipe + internal threaded pipe", and then a secondary mechanical locking is performed by "locking ring + locking bolt", forming a double fixing structure, which effectively resists the vibration and pressure impact during the high temperature asphalt transportation process; 3. The modular design supports quick assembly and disassembly, making it easy to clean residual asphalt, replace damaged parts, or store and transport them. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0018] A road surface asphalt crack sealing device, combined with an attached Figure 1-4 As shown, it includes a crack filling tube, an extrusion head 1, and a delivery tube. The crack filling tube includes multiple connecting tubes 2, which are arranged sequentially and connected by a positioning mechanism. The extrusion head 1 is located at one end of the crack filling tube and is connected to the endmost connecting tube 2 by a positioning mechanism. The delivery tube is connected to the other end of the crack filling tube by a positioning mechanism. The delivery tube includes a delivery hose 3 and a delivery sleeve 4. One end of the delivery hose 3 is connected to the crack filling liquid, and the other end is connected to the delivery sleeve 4. The delivery sleeve 4 is connected to the other end of the crack filling tube by a positioning mechanism. It can be assembled as needed and facilitates disassembly and cleaning after use. The positioning mechanism includes an external threaded tube 5 and an internal threaded tube 6; an external threaded tube 5 is fixedly provided on the outer wall of one end of the connecting tube 2, and an internal threaded tube 6 adapted to the external threaded tube 5 is provided inside the other end. After the connecting tubes 2 are arranged in sequence, the internal threaded tube 6 between adjacent connecting tubes 2 is threadedly connected to the external threaded tube 5. An external threaded tube 5 is provided on the extrusion head 1, and an internal threaded tube 6 is provided inside the material conveying sleeve 4. It also includes a sealing ring 7, which is placed around the external threaded pipe 5 and closely attached to the outer wall of the end of the connecting pipe 2. After the internal threaded pipe 6 between adjacent connecting pipes 2 is threadedly connected to the external threaded pipe 5, the sealing ring 7 is tightly attached between the outer walls of the two connecting pipes 2, thereby improving the tightness of the connection. Example 2

[0019] Based on Example 1, combined with Appendix Figure 2 As shown, the positioning mechanism also includes a locking ring 8; locking rings 8 are welded and fixed to the outer walls of both ends of each connecting pipe 2. After the internal threaded pipe 6 and the external threaded pipe 5 between adjacent connecting pipes 2 are connected by thread, the adjacent locking rings 8 are tightly attached. After the locking bolt passes through the preset through hole 9 on the locking ring 8, it is tightened by the nut to improve the tightness of the connection. Each connecting pipe 2 is equipped with an auxiliary handle 10, and an anti-slip pad is attached to the auxiliary handle 10 for easy hand use.

[0020] In the specific implementation of this utility model, firstly, the crack is cleaned to remove dust, gravel and moisture, ensuring that the grouting surface is dry and clean. Select an appropriate number of connecting pipes 2 and arrange them in sequence. Insert the external threaded pipe 5 of the first connecting pipe 2 into the internal threaded pipe 6 of the second connecting pipe, and rotate clockwise until fully screwed in. Align the locking rings 8 at the ends of the two connecting pipes 2, insert the locking bolts and tighten them with nuts to complete the double locking of the joint. Repeat the above steps until the required total length is reached. Install an extrusion head 1 with an external threaded tube 5 on the frontmost connecting pipe 2, tighten it with an internal threaded tube 6, and fix it with a locking ring 8. Connect a material conveying sleeve 4 (containing an internal threaded tube 6) to the rearmost connecting pipe 2, and then connect one end of the material conveying hose 3 to the outlet of the grouting liquid storage tank. Turn on the crack filling liquid delivery pump so that the high temperature asphalt flows out continuously through the delivery hose 3 → delivery sleeve 4 → each connecting pipe 2 → extrusion head 1. The operator holds the auxiliary handle 10 on each connecting pipe 2 and moves the extrusion head 1 slowly and evenly along the crack to control the extrusion amount and ensure that the crack is fully filled. After the grouting is completed, turn off the delivery pump, cut off the material source, disassemble all connecting parts, and promptly flush the internal residual asphalt with a high-temperature cleaning agent or diesel to prevent it from hardening and clogging.
