Description

Technical Field

[0001] This utility model belongs to the field of highway maintenance technology, specifically, it relates to a road surface crack sealing machine for highway maintenance. Background Technology

[0002] Cracks are one of the main forms of highway defects, with transverse and longitudinal cracks being the most common linear cracks. After a highway is built and opened to traffic, it will gradually deteriorate in quality due to wear and impact from wheels, erosion and weathering from natural forces such as rainstorms, floods, wind and sand, snow, sun, and ice melting, as well as human damage and some defects left over from the construction. Therefore, maintenance and repair measures must be taken and continuous updates and improvements must be made.

[0003] When cracks appear on the road surface, in order to prevent the cracks from widening, measures are usually taken first to clean the cracks, and then asphalt is sprayed into the cracks using a crack sealing machine. During the crack sealing process, asphalt is sprayed onto the cracks through a nozzle to achieve the maintenance effect of the road surface. However, when the crack sealing machine is moved to the road surface that needs maintenance, the nozzle needs to be connected to a material guide hose, which causes the nozzle to come into contact with the ground when the crack sealing machine is moved. This causes wear and tear on the nozzle when it comes into contact with the ground, which is not conducive to the protection of the asphalt nozzle. In view of this, this utility model is proposed to solve the above problems by providing a road surface crack sealing machine for road maintenance. Utility Model Content

[0004] To address the problem that when moving a crack sealing machine to a road surface requiring maintenance, the nozzle needs to be connected to a material guide hose, causing the nozzle to come into contact with the ground during movement. This leads to wear and tear on the nozzle during movement, which is detrimental to the protection of the asphalt nozzle. The basic concept of the technical solution adopted in this utility model is as follows:

[0005] A road surface crack sealing machine for highway maintenance includes a base plate. A material conveying pipe is fixedly mounted on the base plate. A material guiding hose is fixedly connected to the bottom end of the material conveying pipe. An asphalt nozzle is fixedly connected to the bottom end of the material guiding hose. An installation plate is fixedly connected to the outer wall of the asphalt nozzle. Symmetrically arranged limiting grooves are formed on both sides of the installation plate. An installation seat is fixedly connected to the bottom outer wall of the base plate. A connecting groove is formed at the bottom of the installation seat. The width of the connecting groove is slightly larger than the width of the installation plate. Symmetrically arranged movable grooves are formed on opposite sides of the connecting groove. The two movable grooves contain... The wall is slidably connected with wedge-shaped limiting blocks, which are adapted to the limiting grooves. Compression springs are fixedly connected to the inner wall of one side of each of the two movable grooves. One end of each of the two compression springs is fixedly connected to the outer wall of one side of each of the two limiting blocks. Symmetrically arranged through holes are opened on both sides of the mounting base, and sliding rods are slidably connected to the inner wall of each through hole. The opposite ends of each of the two sliding rods are fixedly connected to the outer wall of one side of each of the two limiting blocks, and the compression springs are sleeved on the sliding rods. A connecting plate is fixedly connected to the end of each of the two sliding rods located outside the mounting base.

[0006] In a preferred embodiment of this utility model, a storage tank and an asphalt pump are fixedly installed on the top of the base plate. The inlet of the asphalt pump is connected to the storage tank through a pipe, and the top end of the conveying pipe is connected to the outlet of the asphalt pump.

[0007] In a preferred embodiment of the present invention, symmetrically arranged support frames are fixedly installed on both sides of the bottom of the substrate, and symmetrically arranged casters are installed at the bottom of each support frame. A push frame is fixedly installed on the outer wall of one side of the top of the substrate.

[0008] In a preferred embodiment of this utility model, the two connecting plates are fixedly connected to the outer walls of opposite sides by symmetrically arranged first connecting frames, and each of the two first connecting frames is hinged with a guide rod.

[0009] In a preferred embodiment of the present invention, an L-shaped mounting bracket is fixedly connected to the bottom outer wall of the substrate, a mounting rod is fixedly connected to the top outer wall of the mounting bracket, and a lifting plate is slidably arranged on the outer wall of the mounting rod.

[0010] In a preferred embodiment of this utility model, the outer walls on both sides of the lifting plate are fixedly connected with symmetrically arranged second connecting frames, and the two guide rods are respectively hinged to one end on the two second connecting frames.

[0011] In a preferred embodiment of this utility model, the lifting plate and the mounting frame are fixedly connected to the same return spring on opposite outer walls. The return spring is sleeved on the mounting rod, and an L-shaped pull rod is fixedly connected to one outer wall of the lifting plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] In this invention, when the device is moved to the road surface requiring maintenance, the mounting plate is first rotated, causing the asphalt nozzle to rotate as well. The mounting plate rotates until it reaches the inner side of the connecting groove. At this point, the mounting plate presses against the two limiting blocks until the limiting grooves on both sides of the mounting plate move to one side of the limiting blocks. Then, under the action of two compression springs, the two limiting blocks are pushed into the two limiting grooves, achieving a positioning effect on the mounting plate. This allows for the storage of the asphalt nozzle, preventing wear caused by contact between the nozzle and the ground during movement of the device, and thus protecting the asphalt nozzle. The device functions as follows: After the asphalt nozzle is retracted, it can be pushed to the road surface requiring maintenance. When the device is moved to the road surface requiring maintenance, the two connecting plates move in opposite directions, causing the two connecting plates to drive the two sliding rods to move in opposite directions. The two sliding rods then drive the two limiting blocks to move in opposite directions until the two limiting blocks disengage from the two limiting grooves. Then, rotating the mounting plate will reset the asphalt nozzle to its initial state, positioning the asphalt nozzle above the crack. Asphalt is then delivered to the asphalt nozzle and sprayed onto the crack through the installed asphalt pump, delivery pipe, and guide hose, thus completing the crack filling work on the road surface.

[0023] like Figures 1 to 5 As shown

[0024] A road surface crack sealing machine for highway maintenance includes a base plate 1. A material conveying pipe 3 is fixedly installed on the base plate 1. A guide hose 4 is fixedly connected to the bottom end of the material conveying pipe 3. An asphalt nozzle 5 is fixedly connected to the bottom end of the guide hose 4. An installation plate 6 is fixedly connected to the outer wall of the asphalt nozzle 5. The installation plate 6 has symmetrically arranged limiting grooves 13 on both sides. An installation seat 10 is fixedly connected to the bottom outer wall of the base plate 1. A connecting groove 12 is opened at the bottom of the installation seat 10. The width of the connecting groove 12 is slightly larger than the width of the installation plate 6. Symmetrically arranged movable grooves are opened on opposite sides of the connecting groove 12. The inner walls of the two movable grooves 24 are slidably connected with wedge-shaped limiting blocks 15, which are adapted to the limiting grooves 13. Compression springs 25 are fixedly connected to one side of the inner wall of each of the two movable grooves 24, with one end of each compression spring 25 fixedly connected to the outer wall of one side of each limiting block 15. When the device is moved to the road surface requiring maintenance, the mounting plate 6 is first rotated, causing the mounting plate 6 to drive the asphalt nozzle 5 to rotate until the mounting plate 6 rotates to the inside of the connecting groove 12. At this point, the mounting plate 6 controls the two limiting blocks 13. The locking blocks 15 are pressed until the limiting grooves 13 on both sides of the mounting plate 6 move to one side of the two limiting locking blocks 15. At this time, under the action of the two compression springs 25, the two limiting locking blocks 15 can be pushed into the two limiting grooves 13 respectively, achieving the positioning effect of the mounting plate 6, thereby realizing the storage of the asphalt nozzle 5 and avoiding the asphalt nozzle 5 from contacting the ground and causing wear when moving the device. The mounting base 10 has symmetrically arranged through holes on both sides, and the inner walls of the through holes are slidably connected to sliding rods 23. The two sliding rods 23 3. The opposite ends are respectively fixedly connected to the outer wall of one side of the two limiting blocks 15, and the compression spring 25 is sleeved on the slide rod 23. The two slide rods 23 are fixedly connected to the connecting plate 14 at the outer end of the mounting base 10. The bottom sides of the base plate 1 are fixedly installed with symmetrically arranged support frames 7, and the bottom ends of the support frames 7 are all equipped with symmetrically arranged universal wheels. The top side outer wall of the base plate 1 is fixedly installed with a push frame 8. After the asphalt nozzle 5 is retracted, the device can be pushed to the road surface that needs maintenance by the push frame 8 and the support frame 7.

[0025] In a specific embodiment, a storage tank 2 and an asphalt pump 9 are fixedly installed on the top of the substrate 1. The inlet of the asphalt pump 9 is connected to the storage tank 2 via a pipe. The top end of the conveying pipe 3 is connected to the outlet of the asphalt pump 9. Two connecting plates 14 are fixedly connected to the outer walls of opposite sides with symmetrically arranged first connecting frames 19. Guide rods 20 are hinged on both first connecting frames 19. An L-shaped mounting frame 11 is fixedly connected to the bottom outer wall of the substrate 1. A mounting rod 16 is fixedly connected to the top outer wall of the mounting frame 11. A lifting plate 17 is slidably arranged on the outer wall of the mounting rod 16. Second connecting frames 21 are fixedly connected to the outer walls of both sides of the lifting plate 17. Two guide rods 20 are hinged to the two second connecting frames 21 at opposite ends. The same return spring 18 is fixedly connected to the outer walls of the lifting plate 17 and the mounting frame 11 on opposite sides. The return spring 18 is sleeved on the mounting rod 16. An L-shaped pull rod 22 is fixedly connected to the outer wall of one side of the lifting plate 17. When the mounting plate 17 is in use, the pull rod 22 is used. When the device is moved to the road surface requiring maintenance, the pull rod 22 is pulled downwards, which in turn moves the lifting plate 17 downwards. The lifting plate 17 then moves the two second connecting frames 21 downwards. The two first connecting frames 19, which are in conjunction with the device, cause the tilt angle of the two guide rods 20 to change. With the tilt angle of the two guide rods 20 changed, the two first connecting frames 19 can drive the two connecting plates 14 to move in opposite directions. This causes the two connecting plates 14 to drive the two sliding rods 23 to move in opposite directions. The two sliding rods 23 then drive the two limiting blocks 15 to move in opposite directions until the two limiting blocks 15 disengage from the two limiting grooves 13. Then, rotating the mounting plate 6 will reset the asphalt nozzle 5 to its initial state, positioning the asphalt nozzle 5 above the crack. Then, the asphalt pump 9 is turned on, and the asphalt is delivered to the asphalt nozzle 5 and sprayed onto the crack using the delivery pipe 3 and the guide hose 4, thus completing the crack filling work on the road surface.

[0026] The implementation principle of a road surface crack sealing machine for highway maintenance in this embodiment is as follows:

[0027] When moving this device to the road surface requiring maintenance, first rotate the mounting plate 6, causing the asphalt nozzle 5 to rotate until the mounting plate 6 rotates to the inside of the connecting groove 12. At this time, the mounting plate 6 presses against the two limiting blocks 15 until the limiting grooves 13 on both sides of the mounting plate 6 move to one side of the two limiting blocks 15. Then, under the action of the two compression springs 25, the two limiting blocks 15 can be pushed into the two limiting grooves 13 respectively, achieving the positioning effect of the mounting plate 6, thereby realizing the storage of the asphalt nozzle 5 and avoiding wear caused by the asphalt nozzle 5 contacting the ground when moving this device. After the asphalt nozzle 5 is stored, the device can be pushed to the road surface requiring maintenance by the set push frame 8 and support frame 7. When the device moves to the road surface requiring maintenance, pull the pull rod 22 downward. 22 drives the lifting plate 17 to move downwards, and the lifting plate 17 drives the two second connecting frames 21 to move downwards. The two first connecting frames 19, which are set in cooperation, change the tilt angle of the two guide rods 20. When the tilt angle of the two guide rods 20 changes, the two first connecting frames 19 can drive the two connecting plates 14 to move in opposite directions, so that the two connecting plates 14 can drive the two sliding rods 23 to move in opposite directions. The two sliding rods 23 drive the two limiting blocks 15 to move in opposite directions until the two limiting blocks 15 are disengaged from the two limiting grooves 13 respectively. Then, rotating the mounting plate 6 can drive the asphalt nozzle 5 to return to the initial state, so that the asphalt nozzle 5 is above the crack. Then, the asphalt pump 9 is turned on, and the asphalt is transported to the asphalt nozzle 5 and sprayed onto the crack in cooperation with the material delivery pipe 3 and the material guide hose 4, so as to realize the crack filling work of the road surface.
