Description

Technical Field

[0001] The invention relates to the technical field of potting, in particular to a potting machine for highway engineering. Background Art

[0002] In the process of highway construction, caulking machine is an essential mechanical equipment. After the road is paved, due to weather reasons and the influence of chemical reactions such as asphalt, some cracks will inevitably appear on the road surface. The caulking machine can be used to repair the cracks in the road surface, making the road surface smooth and flat, and increasing the service life of the road.

[0003] For example, the announcement number CN210315173U proposes a sealing machine for highway engineering, including a basic handheld sealing gun, the top of which is fixedly connected to a first fixed block, the interior of which is plugged with a first center column, both ends of which are fixedly connected to functional scribing rings, one side of the basic handheld sealing gun is fixedly connected to a second fixed block, the interior of the second fixed block is sleeved with a second center column, and the outer surface of the second center column is sleeved with a connecting sleeve. The sealing machine for highway engineering can separate the exhaust pipe from the discharge port of the basic handheld sealing gun by providing a connecting sleeve, so that cleaning can be done before grouting, which is conducive to the smooth progress of grouting. By providing a baffle, a good field of vision is provided to the staff, and by providing a functional scribing ring, materials can be saved and the ground can be leveled, which greatly improves the practicality of the device.

[0004] At present, in the rainy season, when the crack sealing operation of highway is carried out, in order to avoid sudden rain, which causes the contact of rainwater with asphalt and affects the asphalt sealing effect, it is necessary to carry out waterproofing after the sealing is completed. However, the sealing and waterproofing operations cannot be carried out at the same time. Most of the time, waterproof cloth is laid on the road surface after the sealing is completed. However, there may be a sudden rain when the sealing is not completed, which will still affect the asphalt in the sealing area. At the same time, the current waterproof cloth is laid over a large area, and the unsealed road surface is also laid. If the surface is damaged, the entire sealing area will still be eroded by rain, which has limitations. In addition, during the sealing process, the asphalt will flow along both sides of the crack, and only part of the asphalt will enter the crack. In order to avoid the sealing effect, it is necessary to manually shovel the asphalt into the crack, which is cumbersome. Moreover, due to the excessive damage to some road surfaces, the crack depth is large. Simply shoveling asphalt into the crack makes it difficult for the asphalt to seal the deeper cracks.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to solve the problem of sealing cracks in highways during rainy seasons, in order to avoid sudden rain, which may cause rainwater to contact with asphalt and affect the asphalt sealing effect, waterproofing treatment needs to be performed after the sealing is completed. However, the sealing and waterproofing operations cannot be carried out at the same time. Most of the time, waterproof cloth is laid on the road surface after the sealing is completed. However, if it rains suddenly before the sealing is completed, the asphalt in the sealing area will still be affected. In addition, the current waterproof cloth laying range is large, and the unsealed road surface is also laid. If the surface is damaged, the entire sealing area will still be eroded by rain. There are limited technical problems, such as Figure 1 - Fig. 9 As shown, the following preferred technical solutions are provided:

[0036] A filling machine for highway engineering includes a bracket 1, a universal wheel 2 is symmetrically connected to the bottom end of the bracket 1, a slot body 11 is symmetrically opened at the bottom end of the bracket 1, a transmission shaft 210 is rotatably connected to the inner side wall of each slot body 11, one end of the transmission shaft 210 passes through the slot body 11 and the side wall of the bracket 1, and the side wall is fixedly connected to a moving wheel 211, a mixing box 21 is fixedly connected to the top of the bracket 1, a feeding pipe 22 is symmetrically fixedly connected to the top of the mixing box 21, a motor 23 is fixedly connected to the top of the mixing box 21, and a rotating shaft 24 is fixedly connected to the output end of the motor 23, one end of the rotating shaft 24 passes through the top wall of the mixing box 21 and extends to the inside of the mixing box 21, and the side of the rotating shaft 24 passes through the top wall of the mixing box 21. A plurality of stirring blades 25 are symmetrically fixedly connected to the wall, and a resistance wire is arranged inside each stirring blade 25. When the stirring blades 25 rotate, the asphalt raw materials can be mixed and heated, so as to achieve uniform heating of the asphalt raw materials, so that the internal and external temperatures of the asphalt raw materials are heated uniformly, and the asphalt is more uniform, so as to facilitate filling. The bottom wall of the mixing box 21 is symmetrically fixedly connected with inclined blocks 26. The plurality of inclined blocks 26 have a guiding function to guide the melted asphalt raw materials. An extrusion tube 27 is fixedly connected through the bottom end of the inclined block 26. One end of the extrusion tube 27 passes through the bottom wall of the mixing box 21 and the bracket 1 in sequence, and a control valve 28 is installed inside the extrusion tube 27.

[0037] A protection component 3 is fixedly installed at the bottom end of the bracket 1. By setting the protection component 3, after the asphalt raw material is melted, the control valve 28 is opened, and the asphalt is discharged along the extrusion tube 27. By controlling the push handle 29 and with the cooperation of the universal wheel 2, the extrusion tube 27 is moved along the cracks of the road surface, so that the asphalt is poured along the cracks. During the movement, the moving wheel 211 and the transmission shaft 210 rotate, so that the first synchronous wheel 31 rotates, and with the cooperation of the synchronous belt 35, the second synchronous wheel 34 and the connecting shaft 33 rotate synchronously; during the pouring process, the electromagnet 37 is energized to generate The magnetism is generated, so that the adjacent surfaces of the electromagnet 37 and the permanent magnet 315 generate special-shaped magnetic poles. Under the action of the magnetic attraction, the telescopic rod 39 is driven to extend, so that the clamping block 310 on the side wall of the telescopic rod 39 enters the inside of the clamping groove 36, wherein the adjacent surfaces of the clamping block 310 and the clamping groove 36 are both inclined structures, so that they can be easily clamped into the inside of the clamping groove 36. Under the clamping cooperation of the clamping groove 36 and the clamping block 310, the telescopic rod 39 and the connecting shaft 33 are synchronously rotated, so that the waterproof roll cloth 311 is unwound, and the unwound waterproof cloth will be along the bottom of the guide plate 38. The waterproof cloth can be moved at the inclined position, so that the waterproof cloth can be laid to the top of the crack that has been sealed for protection. Lead strips are arranged on both sides of the waterproof cloth to increase the weight of the waterproof cloth and prevent the waterproof cloth from being blown up by external factors and affecting the waterproof effect. The width of the waterproof cloth is greater than the width of the crack, so that the cracks in the road surface can be effectively laid for protection. Compared with the prior art that directly lays the waterproof cloth on the entire sealed road surface, the device only needs to lay waterproof cloth on the sealed part of the road surface, which reduces the use of waterproof cloth and carries out regional laying, thereby improving the waterproof effect of the sealing. When a section of crack is sealed, Start the electric push rod 313, drive the cutter 314 to cut the waterproof cloth, and change the current direction of the electromagnet 37, so that the adjacent surfaces of the electromagnet 37 and the permanent magnet 315 produce like magnetic poles. Under the action of magnetic repulsion, the telescopic rod 39 is driven to contract, so that the block 310 on the side wall of the telescopic rod 39 leaves the inside of the clamping groove 36, and the driving source of the telescopic rod 39 is released, so that the waterproof roll 311 stops rotating, and the waterproof roll 311 is prevented from being unwound all the time. When it moves to the next sealing location, the current direction of the electromagnet 37 is changed again, and the operation is repeated to carry out the road crack sealing operation.

[0038] A centralizing component 4 is fixedly installed between the extrusion tube 27 and the protection component 3. By setting the centralizing component 4, in the process of moving and filling along the crack, the roller 43 will roll along the ground, driving the reciprocating screws 42 on both sides to rotate synchronously, so that the threaded sleeves 44 on both sides move back and forth along the reciprocating screws 42, thereby driving the two scrapers 45 to move synchronously, so that the scrapers 45 continuously concentrate the asphalt on both sides of the crack to the crack, and in the process of the two scrapers 45 approaching, the wedge plate 46 on the side wall of the scraper 45 cooperates to push the pressure plate 48 downward, thereby assisting the compaction of the asphalt, so that the asphalt The green can better enter the crack, and as the two scrapers 45 move away from each other, the wedge plate 46 leaves the side wall of the pressure plate 48, and under the elastic action of the spring 47, drives the pressure plate 48 to move upward, so as to facilitate the subsequent auxiliary compaction. The side wall of the reciprocating screw 42 is provided with a groove spacing that is compatible with the diameter of the roller 43. During the rotation of the roller 43, the movement speed of the threaded sleeve 44 along the side wall of the reciprocating screw 42 will not be too fast, affecting the concentration effect of the asphalt. In addition, the length of the scraper 45 is long enough. During the filling movement process, the scraper 45 can repeat the scraping operation on the asphalt that has been scraped again, thereby improving the concentration effect of the asphalt.

[0039] An auxiliary component 5 is installed inside the centralized component 4. By setting the auxiliary component 5, when the two scrapers 45 approach each other, the wedge plate 46 on the side wall of the scraper 45 cooperates to push the pressure plate 48 downward, so that the sealing ring 516 on the side wall of the pressure plate 48 is pressed into the asphalt. Since the asphalt has a certain adhesion, after the sealing ring 516 is pressed into the asphalt, a closed space is formed between the sealing ring 516 and the pressure plate 48. As the two threaded sleeves 44 reciprocate, the piston plate 54 is driven to move synchronously through the connecting plate 53. When the two piston plates 54 move away from each other, the pressure difference generated by the sealed sliding between the piston plate 54 and the sealing chamber 51 is used to draw in external air along the intake pipe 512. When the two piston plates 54 approach each other, the internal pressure increases, and the gas in the sealing chamber 51 is blown into the cavity 510 in the pressure plate 48 through the exhaust pipe 514, and the gas is discharged along the through hole 511. , thereby using air pressure to push the upper layer of asphalt downward along the crack to fill the inside of the crack and further improve the potting effect, wherein a one-way air intake valve 513 is installed inside the air intake pipe 512, so that external air can only enter the sealing chamber 51 along the air intake pipe 512, and a one-way exhaust valve 515 is installed inside the exhaust pipe 514, so that the gas in the sealing chamber 51 can only be discharged along the exhaust pipe 514; since asphalt has a certain adhesion, a part of the asphalt will stick to the bottom of the sealing ring 516, and after the asphalt solidifies, the bottom of the sealing ring 516 will be uneven, affecting the sealing effect, when the two scrapers 45 move away from each other, the first rack plate 56 is driven to move away synchronously, and the meshing action between the rack plate and the cylindrical gear 57 is used to make the second rack plate 58 close to the sealing ring 516, so as to scrape off the asphalt sticking to the bottom of the sealing ring 516, wherein the initial position of the scraper 59 is located on the side wall of the scraper 45.

[0040] The protective component 3 includes a first synchronous wheel 31, which is fixedly connected to the side wall of the transmission shaft 210. A positioning plate 32 is symmetrically fixedly connected to the bottom of the bracket 1. Each side wall of the positioning plate 32 is rotatably connected with a connecting shaft 33.

[0043] In this solution: after the asphalt raw material is melted, the control valve 28 is opened, and the asphalt is discharged along the extrusion tube 27. By controlling the push handle 29 and with the cooperation of the universal wheel 2, the extrusion tube 27 is moved along the cracks in the road surface, so that the asphalt is poured along the cracks. During the movement, the moving wheel 211 and the transmission shaft 210 rotate, so that the first synchronous wheel 31 rotates, and with the cooperation of the synchronous belt 35, the second synchronous wheel 34 and the connecting shaft 33 rotate synchronously; during the pouring process, the electromagnet 37 is energized to generate magnetism, so that the adjacent surfaces of the electromagnet 37 and the permanent magnet 315 generate special-shaped magnetic poles, and under the action of the magnetic attraction, the telescopic rod 39 is driven to extend, so that the block 310 on the side wall of the telescopic rod 39 enters the inside of the clamping groove 36, wherein the adjacent surfaces of the block 310 and the clamping groove 36 are both oblique structures, from The tarpaulin 35 is provided with a plurality of lead strips, and the plurality of lead strips are provided on both sides of the tarpaulin. The ...

[0044] When a section of cracks is sealed, the electric push rod 313 is started to drive the cutter 314 to cut the waterproof cloth, and the current direction of the electromagnet 37 is changed, so that the adjacent surfaces of the electromagnet 37 and the permanent magnet 315 produce like magnetic poles. Under the action of magnetic repulsion, the telescopic rod 39 is driven to contract, so that the block 310 on the side wall of the telescopic rod 39 leaves the inside of the clamping groove 36, and the driving source of the telescopic rod 39 is released, so that the waterproof roll 311 stops rotating, and the waterproof roll 311 is prevented from being unwound all the time. When it moves to the next sealing location, the current direction of the electromagnet 37 is changed again, and the operation is repeated to carry out the road crack sealing operation.

[0045] In order to solve the problem that during the potting process, asphalt will flow along both sides of the crack, and only part of the asphalt will enter the crack, in order to avoid the potting effect, it is necessary to manually shovel the asphalt into the crack, which is a cumbersome technical problem. Fig.10 - Fig.11As shown, the following preferred technical solutions are provided:

The inner wall of the sealed chamber 51 is fixedly connected to an air intake pipe 512, and a one-way air intake valve 513 is installed inside the air intake pipe 512. The inner bottom wall of the sealed chamber 51 is symmetrically fixedly connected to an exhaust pipe 514.

[0052] A one-way exhaust valve 515 is installed inside each exhaust pipe 514 . One end of each exhaust pipe 514 passes through the pressure plate 48 and extends to the inside of the cavity 510 . A plurality of through holes 511 are formed on the inner bottom wall of the cavity 510 .

[0053] The bottom end of the mounting plate 41 is symmetrically fixedly connected with a support plate 55, and the bottom end of each support plate 55 is rotatably connected with a cylindrical gear 57. The side wall of each scraper 45 is fixedly connected with a first rack plate 56, and the first rack plate 56 is embedded and slidably connected to the bottom end of the support plate 55. A second rack plate 58 is slidably connected through the inner wall of the scraper 45. The first rack plate 56 and the second rack plate 58 are both meshed with the cylindrical gear 57, and one end of each second rack plate 58 is fixedly connected with a scraper 59.

[0054] In this solution, when the two scrapers 45 approach each other, the wedge-shaped plate 46 on the side wall of the scraper 45 cooperates to push the pressure plate 48 downward, so that the sealing ring 516 on the side wall of the pressure plate 48 is pressed into the asphalt. Since the asphalt has a certain degree of adhesion, after the sealing ring 516 is pressed into the asphalt, a closed space is formed between the sealing ring 516 and the pressure plate 48. As the two threaded sleeves 44 reciprocate, the piston plate 54 is driven to move synchronously through the connecting plate 53. When the two piston plates 54 move away from each other, the pressure difference generated by the sealed sliding between the piston plate 54 and the sealing chamber 51 is cooperated to drive the external air along the intake pipe 51. 2. When the two piston plates 54 are close to each other, the internal pressure increases, and the gas in the sealed cavity 51 is blown into the cavity 510 in the pressure plate 48 through the exhaust pipe 514, and the gas is discharged along the through hole 511, so that the upper layer of asphalt is pushed downward along the crack by the air pressure to fill the inside of the crack, further improving the potting effect. A one-way air intake valve 513 is installed inside the air intake pipe 512, so that the external air can only enter the sealed cavity 51 along the air intake pipe 512, and a one-way exhaust valve 515 is installed inside the exhaust pipe 514, so that the gas in the sealed cavity 51 can only be discharged along the exhaust pipe 514;

[0055] Asphalt has a certain degree of adhesion, so some asphalt will stick to the bottom of the sealing ring 516. After the asphalt solidifies, the bottom of the sealing ring 516 will become uneven, affecting the sealing effect. When the two scrapers 45 move away from each other, the first rack plate 56 is driven to move away synchronously, and the meshing action between the rack plate and the cylindrical gear 57 is utilized to make the second rack plate 58 approach the sealing ring 516, so as to scrape off the asphalt sticking to the bottom of the sealing ring 516, wherein the scraper 59 is initially located on the side wall of the scraper 45.
