[0002] As is widely known, the asphalt pavement hot melt patch repair machine, also known as the asphalt crack sealing machine, is a type of mechanical equipment specifically used to repair cracks and potholes in asphalt pavements. The asphalt crack sealing machine has advantages such as high construction efficiency, good material sealing, environmental friendliness, and high efficiency and durability. The asphalt crack sealing machine achieves thermal bonding of the material through temperature control, resulting in good adhesion.

[0003] The working principle of the asphalt crack sealing machine is as follows: First, the liquefied gas heating system allows the heat transfer oil to circulate and quickly melt the asphalt. Then, the molten material is transported to the outlet of the delivery pipe by a pressure pump. The asphalt is injected into the crack wall by pressure injection to tightly bond with it and repair the crack.

[0004] When the asphalt crack sealing machine is not in use, the asphalt conveying pipe is placed outside the device. If the conveying pipe is subjected to external impact during the storage period, it will be damaged and cannot be used normally. The conveying pipe needs to be repaired or replaced, which will affect the road repair operation and bring certain shortcomings to the asphalt crack sealing machine. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, one objective of this utility model is to provide an asphalt pavement hot melt patch repair machine to solve the above-mentioned shortcomings of the prior art.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 A hot-melt asphalt pavement repair machine is introduced to address the problem that when an asphalt crack sealing machine is not in use, the asphalt conveying pipe is located outside the device. If the conveying pipe is subjected to external impacts during the storage period, it may be damaged and unable to function properly, requiring repair or replacement of the conveying pipe, which affects the road repair operation and brings certain shortcomings to the asphalt crack sealing machine.

[0027] As a further technical solution proposed in this utility model, the invention includes an asphalt crack sealing machine 1, and further includes: an asphalt tank 1.3, which is mounted on the asphalt crack sealing machine 1; a base plate 3, which is mounted on the asphalt tank 1.3, and a lever 4 is mounted on the base plate 3 via an elastic reset member 5, with a connecting arm 6 rotatably connected to the lever 4; brackets 3.1, which are oppositely mounted on the base plate 3, and each bracket 3.1 is used to abut against the lever 4; and a protective cover 7, which is mounted on the connecting arm 6, and is used to seal the delivery pipe 1.4. When the lever 4 abuts against each bracket 3.1, the elastic reset member 5 is compressed to separate the protective cover 7 from the delivery pipe 1.4. Specifically, the elastic reset member 5 applies a force to the lever 4 to make it slide down, and during this process, the protective cover 7 on the connecting arm 6 descends synchronously to seal the delivery pipe 1.4. Figure 3 As shown in the diagram, during storage, the delivery pipe 1.4 of the asphalt crack sealing machine 1 is protected by the protective cover 7. When in use, the lever 4 is pulled up to move the sliding synchronous linkage arm 6. During this process, the elastic reset member 5 is compressed. When the lever 4 rises to the same height as the bracket 3.1, it rotates and engages with the bracket 3.1 to lock the lever 4. Figure 4As shown in the status, when the delivery pipe 1.4 on the asphalt crack sealing machine 1 is not in use, the device can seal and protect it, weakening or even preventing the delivery pipe from being damaged by external impacts, which would cause the delivery pipe to become unusable and require repair or replacement, thus affecting the road repair work.

[0028] In this embodiment, the elastic reset element 5 is specifically a spring, which is used to apply force to the connecting arm 6 when the protective cover 7 blocks the conveying pipe 1.4, so that the structure is more stable when the conveying pipe 1.4 is blocked. The spring is set between the lever 4 and the base plate 3, and it is sleeved on the lever 4. When the lever 4 rises, the spring is squeezed by the disc on the lever 4 and compressed between the base plates 3. The protective cover 7 is adapted to the conveying pipe 1.4. After the two are in contact, the conveying pipe 1.4 is blocked to a certain extent.

[0029] In another embodiment of this utility model, the lever 4 consists of a T-shaped rod and a disk connected to the T-shaped rod, and each elastic reset member 5 is located between the disk and the base plate 3. Further, as shown... Figure 5 As shown in the diagram, the disc is rotatably connected to the connecting arm 6, causing the lever 4 to rise to the height of the bracket 3.1. When the lever 4 rotates, it is not interfered with by the connecting arm 6. Furthermore, when the T-shaped rod on the lever 4 rotates, it can be mounted on the bracket 3.1. Figure 4 As shown in the figure, the lever 4 is fixed on the bracket 3.1 under the influence of the elastic force of the elastic reset member 5.

[0030] In another embodiment of this utility model, preferably, each bracket 3.1 consists of a U-shaped card holder and a support rod connected to the U-shaped card holder, such as... Figure 4 As shown in the diagram, the U-shaped bracket is used to engage with the T-shaped rod on the lever 4. When the two engage, the elastic reset key 5 is compressed, fixing the T-shaped rod onto the U-shaped bracket. At this time, the protective cover 7 is separated from the conveying pipe 1.4. Figure 4 As shown in the diagram, in this state, the asphalt crack sealing machine 1 can perform crack repair work. The separation of the protective cover 7 from the delivery pipe 1.4 also avoids damage to the protective cover 7 due to high temperature. After the asphalt crack sealing machine 1 finishes working, the protective cover 7 is sealed after the delivery pipe 1.4 has cooled down. Furthermore, high-temperature resistant materials can be installed on the protective cover 7, which is an existing technology. The service life of the protective cover 7 is improved by using high-temperature resistant materials.

[0031] In another embodiment of this utility model, each asphalt tank 1.3 is provided with a guide portion 1.5, which is specifically a strip-shaped groove. Each connecting arm 6 has an overall L-shaped structure, and each connecting arm 6 is provided with a protrusion 6.1 that slides with the guide portion 1.5, such as... Figure 3 As shown in the diagram, the guide portion 1.5 is used to slide with the protrusion 6.1 to improve the stability of the connecting arm 6 during descent and ascent.

[0032] In another embodiment of this utility model, each asphalt crack sealing machine 1 is equipped with an engine 2 and an asphalt tank 1.3. The asphalt crack sealing machine 1 is also equipped with a frame plate 1.1, and a placement cylinder 1.2 is provided on the frame plate 1.1. Further, the placement cylinder 1.2 on the frame plate 1.1 is used to place liquefied petroleum gas. When the asphalt crack sealing machine 1 is working, the engine 2 is started and the liquefied gas heating system is used to make the heat transfer oil circulate and quickly melt the asphalt. Then, the melted material is transported to the outlet of the delivery pipe by a pressure pump. The asphalt is injected into the crack wall by pressure injection and tightly bonded to it for repair. This is the prior art and will not be described in detail.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
