Description

Technical Field

[0001] This invention belongs to the technical field of road paving equipment, specifically a road paving equipment. Background Technology

[0002] Before vehicles enter the construction site, a layer of dustproof cloth is usually laid and moistened with water near the entrance and exit. This is to collect and absorb the impurities scattered on the tires and vehicle body when the vehicles enter the road from the construction site, so as to avoid dust and gravel falling and affecting environmental hygiene and traffic safety. At present, the dustproof cloth is automatically laid on the road surface by the paving equipment. The paving equipment minimizes manual intervention in the process of laying the dustproof cloth, which not only reduces the workload of manual labor, but also improves the laying efficiency of the dustproof cloth.

[0003] Patent CN116752409A discloses a road paving device, including a walking mechanism and a paving mechanism. The paving mechanism is used for laying and cutting dustproof cloth. The paving mechanism includes a telescopic component, a cutting component, and an auxiliary support component. The telescopic component can extend and retract horizontally to pull the material roll, thereby adjusting the length of the dustproof cloth. The telescopic component can also move vertically to move the dustproof cloth vertically. The cutting component includes a cutter for cutting the dustproof cloth. The auxiliary support component is installed on the telescopic component and includes an auxiliary wheel that can move vertically. This solution uses the extension of the telescopic component to pull the material roll, causing the dustproof cloth to be pulled out of the roll and laid along the road surface. The cutter then cuts the cloth to the appropriate length, reducing labor intensity and improving work efficiency.

[0004] In the above-mentioned scheme, when laying dustproof cloth, the telescopic component needs to cooperate with the gripping mechanism and the suction cup to pull the material roll during the process of pulling the material roll. First, the material roll pulling involves many and complex structures, resulting in low efficiency of laying dustproof cloth. Second, after the telescopic component extends, the volume of the entire device increases. Since there are many people and vehicles on the road near the construction site entrance, the increased volume of the entire device during the extension of the telescopic component will hinder the normal passage of people and vehicles, and may easily cause traffic accidents. Therefore, the present invention provides a road paving device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The road paving equipment of the present invention includes a vehicle body, a roller for winding up dustproof cloth is installed inside the vehicle body, a guide column for driving the dustproof cloth is rotatably installed directly below the roller, a cutting knife and a knife sleeve are respectively arranged below the two sets of guide columns, the cutting knife is driven by a first hydraulic cylinder, a movable frame is movably installed inside the vehicle body, a pressure roller is rotatably installed at the lower end of the movable frame, the movable frame is driven by a second hydraulic cylinder, a glue application mechanism is arranged inside the vehicle body, the glue application mechanism includes a glue storage tank, the glue storage tank is movably installed inside the vehicle body, a third hydraulic cylinder for driving the glue storage tank is fixedly installed inside the vehicle body, a feeding port is opened at the bottom of the glue storage tank, two sets of support rods are embedded on both sides of the feeding port, a driven roller, the two sets of support rods are rotatably mounted on the two ends of the driven roller, a glue application roller, the two sets of support rods are rotatably mounted on the two ends of the glue application roller, the glue application roller is rotatably connected to the driven roller, and four sets of wheels for walking are arranged on the outside of the vehicle body;

[0007] This device has a simple structure and is easy to operate. During the process of moving the device, it will simultaneously apply adhesive to the road surface, lay dustproof cloth, and roll the dustproof cloth, which improves the efficiency of laying the dustproof cloth on the road surface. Furthermore, due to the simple structure of this device, the entire device is compact and small in size, which reduces the obstruction to personnel and vehicles during the laying process.

[0008] Preferably, two sets of first guide grooves are provided on both sides of the vehicle body, and first guide rails are provided on both sides of the movable frame and the glue storage box. The first guide rails are slidably connected to the first guide grooves, and a set of rectangular slide grooves are provided on both sides of the vehicle body. The end of the cutting blade is slidably connected to the rectangular slide grooves.

[0009] The cooperation between the first guide rail and the first guide groove guides the movement of the movable frame and the glue storage box, while the rectangular slide guides the movement of the cutting blade.

[0010] Preferably, the support rod includes a rod body, which is embedded in one side of the feed port, a first movable groove on the rod body, a movable plate slidably connected to the first movable groove, a second movable groove on the rod body, a movable block slidably connected to the second movable groove, a first spring located above the movable block, the movable plate being rotatably mounted on the end of the glue-applying roller, the movable block being rotatably mounted on the end of the driven roller, both the movable plate and the movable block being rectangular block-shaped mechanisms, and the first spring being located in the second movable groove;

[0011] Under the elastic force of the first spring, the driven roller and the movable block move downwards, causing the driven roller to block the discharge port. During the turning process of this device, the discharge port is blocked by the driven roller, which prevents the glue from overflowing and being wasted.

[0012] Preferably, the movable frame includes a main frame, a piston rod end of the second hydraulic cylinder fixedly connected to the main frame, a secondary frame movably installed in the main frame, a second spring installed on the secondary frame, two sets of sliders movably installed at both ends of the secondary frame, the sliders being fitted onto the ends of the pressure rollers, a rectangular guide hole being provided on the main frame, a rectangular column being inserted into the rectangular guide hole, the rectangular column being fixedly installed on the secondary frame, a second guide groove being provided at both ends of the secondary frame, a second guide rail being provided on the slider, the second guide rail being slidably connected to the second guide groove, a pin being welded to one side of the slider, and guide grooves being provided on both sides of the main frame, the pin being located in the guide groove, the guide groove being composed of a straight groove and an oblique groove, the pin being driven along the oblique groove to move the slider;

[0013] As the pressure roller approaches the guide post, the length of the dustproof cloth between the pressure roller and the guide post will shorten. At the same time, the rolling of the pressure roller will cause tension on the dustproof cloth. As the length of the dustproof cloth between the pressure roller and the guide post gradually shortens, the dustproof cloth between the pressure roller and the guide post will be straightened. At this time, the main frame will stop pressing down, thus ensuring that the dustproof cloth can fully adhere to the road surface.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This device has a simple structure and is easy to operate. During the movement of the device, it will simultaneously apply adhesive to the road surface, lay dustproof cloth, and roll the dustproof cloth, which improves the efficiency of laying the dustproof cloth on the road surface. Furthermore, due to the simple structure of this device, the entire device is compact and small in size, which reduces the obstruction to personnel and vehicles during the laying process.

[0016] 2. When the glue-applying roller is removed from contact with the road surface, under the action of gravity, the glue-applying roller and the movable plate move downwards, and the movable plate slides along the first movable groove. At this time, the driven roller loses the squeezing force of the glue-applying roller. Under the action of the elastic force of the first spring, the driven roller and the movable block move downwards, causing the driven roller to block the discharge port. During the turning process of this device, the discharge port is blocked by the driven roller, which prevents the glue from overflowing and being wasted.

[0017] 3. After the pressure roller contacts the ground, the main frame continues to move downward along the rectangular column and compresses the second spring. At the same time, the pin on one side of the slider moves upward along the straight groove until the pin enters the inclined groove. Guided by the inclined groove, the pin drives the slider, along with the second guide rail and the pressure roller, to move towards the guide column. The second guide rail slides along the second guide groove, and the pressure roller rolls towards the guide column. As the pressure roller approaches the guide column, the length of the dustproof cloth between the pressure roller and the guide column will shorten. At the same time, the rolling of the pressure roller will cause the dustproof cloth to generate tension. As the length of the dustproof cloth between the pressure roller and the guide column gradually shortens, the dustproof cloth between the pressure roller and the guide column will be straightened. At this time, the main frame stops pressing down, thus ensuring that the dustproof cloth can completely adhere to the road surface. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figures 1 to 3 As shown in the embodiment of the present invention, a road paving device includes a vehicle body 1. A roller 2 for winding up a dustproof cloth 3 is installed inside the vehicle body 1. Guide columns 4 for driving the dustproof cloth 3 are rotatably installed directly below the roller 2. A cutting blade 5 and a blade sleeve 6 are respectively arranged below the two sets of guide columns 4. The cutting blade 5 is driven by a first hydraulic cylinder 7. A movable frame 8 is movably installed inside the vehicle body 1. A pressure roller 9 is rotatably installed at the lower end of the movable frame 8. The movable frame 8 is driven by a second hydraulic cylinder 10. An adhesive application mechanism 11 is provided inside the vehicle body 1. The adhesive application mechanism 11 includes an adhesive storage tank 111, which is movably installed... The third hydraulic cylinder 112, which is installed inside the vehicle body 1, is used to drive the glue storage tank 111. The third hydraulic cylinder 112 is fixedly installed inside the vehicle body 1. The discharge port 113 is opened at the bottom of the glue storage tank 111. Two sets of support rods 114 are embedded on both sides of the discharge port 113. The driven roller 115 is rotatably mounted on both ends of the driven roller 115. The glue coating roller 116 is rotatably mounted on both ends of the glue coating roller 116. The glue coating roller 116 is rotatably connected to the driven roller 115. Four sets of wheels 101 for walking are provided on the outside of the vehicle body 1.

[0031] Specifically, attached Figure 2In the initial state, the pressure roller 9 and the glue-applying roller 116 are both out of contact with the road surface, and the cutting blade 5 is disengaged from the blade sleeve 6. When it is necessary to lay the dustproof cloth 3 on the road surface, a set of guide columns 4 are driven by a motor to rotate. As the guide columns 4 rotate, the dustproof cloth 3 is pulled out from the roll roller 2, and after a portion of the dustproof cloth 3 falls onto the road surface, the rotation of the guide columns 4 is paused, and the third hydraulic cylinder 112 is activated. The third hydraulic cylinder 112 moves the entire glue-applying mechanism 11 downward until the glue-applying roller 116 touches the road surface. Then, the glue is poured into the glue storage tank 111, and the wheels 101 are driven by a motor to move the entire device forward. During the movement, a portion of the dustproof cloth 3 that falls onto the road surface will be pulled along the road surface. At the same time, the adhesive roller 116 will roll along the road surface, and the rolling adhesive roller 116 will drive the driven roller 115 to rotate. As the driven roller 115 rotates, the adhesive in the adhesive storage tank 111 will flow onto the adhesive roller 116 along with the driven roller 115. Then, as the adhesive roller 116 rolls, the adhesive is brushed onto the road surface until the end of the dustproof cloth 3 contacts the road surface coated with adhesive. The device then stops moving forward and activates the second hydraulic cylinder 10. The second hydraulic cylinder 10 causes the movable frame 8 and the pressure roller 9 to move downwards until the pressure roller 9... The dustproof cloth 3 is pressed down, making it tightly adhere to the surface coated with adhesive. The device continues to move forward, and the guide column 4 rotates synchronously with the device. The dustproof cloth 3 is automatically pulled out from the roller 2 and laid on the surface coated with adhesive. Simultaneously, the pressure roller 9 rolls the dustproof cloth 3 along the surface coated with adhesive, ensuring complete adhesion between the dustproof cloth 3 and the surface. When the adhesive roller 116 reaches the end of the surface, it is detached from the surface. At the same time, the first hydraulic cylinder 7 is activated, causing the cutting blade 5 to move towards the blade sleeve 6. The cutting edge of the cutting blade 5 pushes the dustproof cloth 3 towards the blade sleeve 6. As the port moves, the cutting blade 5 enters the blade sleeve 6, cutting the dustproof cloth 3. At this point, the guide column 4 stops rotating, and the rolling pressure roller 9 rolls the remaining dustproof cloth 3 onto the road surface coated with adhesive. Compared with the prior art, this device has a simple structure and is easy to operate. During the movement of the device, adhesive is applied to the road surface, dustproof cloth 3 is laid, and dustproof cloth 3 is rolled, which improves the efficiency of laying the dustproof cloth 3 onto the road surface. Furthermore, due to the simple structure of this device, the entire device is compact and small in size, reducing the obstruction to personnel and vehicles during operation.

[0032] like Figure 4 As shown, two sets of first guide grooves 102 are provided on both sides of the vehicle body 1. First guide rails 81 are provided on both sides of the movable frame 8 and the glue storage box 111. The first guide rails 81 are slidably connected to the first guide grooves 102. A set of rectangular slide grooves 103 are provided on both sides of the vehicle body 1. The end of the cutting blade 5 is slidably connected to the rectangular slide grooves 103.

[0033] Specifically, when the movable frame 8 and the glue storage box 111 move, the first guide rails 81 on the movable frame 8 and the glue storage box 111 slide along the corresponding first guide grooves 102. The cooperation between the first guide rails 81 and the first guide grooves 102 guides the movement of the movable frame 8 and the glue storage box 111. When the cutting blade 5 moves, both ends of the cutting blade 5 will slide along the corresponding rectangular slide grooves 103. The rectangular slide grooves 103 guide the movement of the cutting blade 5.

[0034] like Figure 5 and Figure 6 As shown, the support rod 114 includes a rod body 1141, which is embedded in one side of the feed port 113. A first movable groove 1142 is opened on the rod body 1141, a movable plate 1143 is slidably connected to the first movable groove 1142, a second movable groove 1144 is opened on the rod body 1141, a movable block 1145 is slidably connected to the second movable groove 1144, and a first spring 1146 is located above the movable block 1145. The movable plate 1143 is rotatably mounted on the end of the glue coating roller 116, and the movable block 1145 is rotatably mounted on the end of the driven roller 115. Both the movable plate 1143 and the movable block 1145 are rectangular block-shaped mechanisms, and the first spring 1146 is located in the second movable groove 1144.

[0035] Specifically, the width of the dustproof cloth 3 is fixed. When the area where the dustproof cloth 3 is laid on the road surface is relatively large, this device needs to go back and forth multiple times to complete the laying. During the back and forth process, this device needs to turn around multiple times. During the turning process, due to the gap between the driven roller 115 and the discharge port 113, the adhesive will continue to flow out from the gap between the driven roller 115 and the discharge port 113. The flowing adhesive will fall onto the coating roller 116. As the amount of adhesive on the coating roller 116 increases, the adhesive on the coating roller 116 will fall onto the area of ​​the road surface where the dustproof cloth 3 does not need to be laid, resulting in the waste of adhesive. Therefore, when the coating roller 116 is used to coat the road surface, the outer ring of the coating roller 116... The adhesive roller 116 is in close contact with the outer ring of the driven roller 115, and the first spring 1146 is compressed by the movable block 1145. When the adhesive roller 116 is separated from the road surface, under the action of gravity, the adhesive roller 116 and the movable plate 1143 move downward, and the movable plate 1143 slides along the first movable groove 1142. At this time, the driven roller 115 loses the squeezing force of the adhesive roller 116. Under the action of the elastic force of the first spring 1146, the driven roller 115 and the movable block 1145 move downward, so that the driven roller 115 blocks the discharge port 113. During the turning process of this device, the discharge port 113 is blocked by the driven roller 115, which avoids the overflow and waste of adhesive.

[0036] Example 2

[0037] like Figure 7 and Figure 8As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the movable frame 8 includes a main frame body 801, the piston rod end of the second hydraulic cylinder 10 is fixedly connected to the main frame body 801, a secondary frame body 802 is movably installed inside the main frame body 801, a second spring 803 is provided on the secondary frame body 802, two sets of sliders 804 are movably installed at both ends of the secondary frame body 802, the sliders 804 are fitted onto the ends of the pressure roller 9, a rectangular guide hole 8011 is provided on the main frame body 801, a rectangular column 805 is inserted into the rectangular guide hole 8011, and the rectangular column... 805 is fixedly installed on the secondary frame 802. The secondary frame 802 has a second guide groove 8021 at both ends. The slider 804 is provided with a second guide rail 8041. The second guide rail 8041 is slidably connected to the second guide groove 8021. A pin 8042 is welded to one side of the slider 804. The main frame 801 has guide grooves 8012 on both sides. The pin 8042 is located in the guide groove 8012. The guide groove 8012 is composed of a straight groove 121 and an inclined groove 122. The pin 8042 is driven along the inclined groove 122 to move the slider 804.

[0038] Specifically, before the pressure roller 9 presses down on the dustproof cloth 3, a portion of the dustproof cloth 3 that has fallen onto the road surface has already been pulled along the road surface. However, this portion of the dustproof cloth 3 is only unfolded and not straightened. At this time, this portion of the dustproof cloth 3 is relatively loose, and it cannot be guaranteed that there are no wrinkles on the dustproof cloth 3. If the dustproof cloth 3 is laid on the road surface, when the pressure roller 9 rolls this portion of the dustproof cloth 3, the guide column 4 pulls the dustproof cloth 3 out of the roller 2 at the same time. This will keep the dustproof cloth 3 between the pressure roller 9 and the guide column 4 relatively loose. The loose dustproof cloth 3 is prone to wrinkles when rolled onto the road surface, causing the dustproof cloth 3 to not be able to fully adhere to the road surface. Therefore, during the process of the movable frame 8 pressing down together with the pressure roller 9, after the pressure roller 9 contacts the ground, the main frame 801 continues to move downward along the rectangular column 805 and compresses the second spring 8. 03. Simultaneously, the pin 8042 on one side of the slider 804 moves upward along the straight groove 121 until the pin 8042 enters the inclined groove 122. Under the guidance of the inclined groove 122, the pin 8042 drives the slider 804, together with the second guide rail 8041 and the pressure roller 9, to move towards the guide post 4. The second guide rail 8041 slides along the second guide groove 8021. At the same time, the pressure roller 9 will roll towards the guide post 4. As the pressure roller 9 approaches the guide post 4, the length of the dustproof cloth 3 between the pressure roller 9 and the guide post 4 will become shorter. At the same time, the rolling of the pressure roller 9 will cause the dustproof cloth 3 to generate tension. As the length of the dustproof cloth 3 between the pressure roller 9 and the guide post 4 gradually shortens, the dustproof cloth 3 between the pressure roller 9 and the guide post 4 will be straightened. At this time, the main frame 801 stops pressing down, thereby ensuring that the dustproof cloth 3 can completely adhere to the road surface.

[0039] Working principle: A set of guide columns 4 are driven by a motor to rotate. As the guide columns 4 rotate, the dustproof cloth 3 is pulled out from the roller 2, causing a portion of the dustproof cloth 3 to fall onto the road surface. The rotation of the guide columns 4 is then paused, and the third hydraulic cylinder 112 is activated. The third hydraulic cylinder 112 moves the entire adhesive application mechanism 11 downwards until the adhesive application roller 116 touches the road surface. Then, the adhesive is poured into the adhesive storage tank 111. The motor drives the wheels 101, propelling the entire device forward. During this movement, the dustproof cloth 3 falls onto the road surface. A portion of the dustproof cloth 3 will be pulled along the road surface, while the adhesive roller 116 will roll along the road surface. The rolling adhesive roller 116 will drive the driven roller 115 to rotate. As the driven roller 115 rotates, the adhesive in the adhesive storage tank 111 will flow onto the adhesive roller 116. Then, as the adhesive roller 116 rolls, the adhesive is brushed onto the road surface until the end of the dustproof cloth 3 contacts the adhesive-coated road surface. The device then pauses its forward movement and starts. The second hydraulic cylinder 10 moves the movable frame 8 and the pressure roller 9 downwards until the pressure roller 9 presses down on the dustproof cloth 3, making the dustproof cloth 3 tightly adhere to the road surface coated with adhesive. At this point, the device continues to move forward, and the guide column 4 rotates synchronously with the device. The dustproof cloth 3 will automatically be pulled out from the roller 2 and laid on the road surface coated with adhesive. Simultaneously, the pressure roller 9 rolls along the road surface coated with adhesive, pressing the dustproof cloth 3 to ensure complete contact between the dustproof cloth 3 and the road surface coated with adhesive. When the adhesive roller 116 reaches the end of the road surface, it is detached from the road surface. At the same time, the first hydraulic cylinder 7 is activated, which moves the cutting blade 5 towards the blade sleeve 6. The cutting blade 5 pushes the dustproof cloth 3 towards the end of the blade sleeve 6. When the cutting blade 5 enters the blade sleeve 6, it cuts the dustproof cloth 3. At this time, the guide column 4 stops rotating, and the rolling pressure roller 9 rolls the remaining dustproof cloth 3 onto the road surface coated with adhesive.

[0040] When the glue-applying roller 116 is applying the road surface, the outer ring of the glue-applying roller 116 is in close contact with the outer ring of the driven roller 115, and the first spring 1146 is compressed by the movable block 1145. When the glue-applying roller 116 is separated from the road surface, under the action of gravity, the glue-applying roller 116 and the movable plate 1143 move downward, and the movable plate 1143 slides along the first movable groove 1142. At this time, the driven roller 115 loses the squeezing force of the glue-applying roller 116. Under the action of the elastic force of the first spring 1146, the driven roller 115 and the movable block 1145 move downward, so that the driven roller 115 blocks the discharge port 113. During the turning process of this device, the discharge port 113 is blocked by the driven roller 115, which avoids glue overflow and glue waste.

[0041] During the downward pressing process of the movable frame 8 and the pressure roller 9, after the pressure roller 9 contacts the ground, the main frame 801 continues to move downward along the rectangular column 805 and compresses the second spring 803. At the same time, the pin 8042 on one side of the slider 804 moves upward along the straight groove 121 until the pin 8042 enters the inclined groove 122. Guided by the inclined groove 122, the pin 8042 drives the slider 804, together with the second guide rail 8041 and the pressure roller 9, to move towards the guide column 4. 041 slides along the second guide groove 8021, while the pressure roller 9 rolls towards the guide post 4. As the pressure roller 9 approaches the guide post 4, the length of the dustproof cloth 3 between the pressure roller 9 and the guide post 4 will become shorter. At the same time, the rolling of the pressure roller 9 will cause the dustproof cloth 3 to generate tension. As the length of the dustproof cloth 3 between the pressure roller 9 and the guide post 4 gradually shortens, the dustproof cloth 3 between the pressure roller 9 and the guide post 4 will be straightened. At this time, the main frame 801 stops pressing down, thereby ensuring that the dustproof cloth 3 can completely adhere to the road surface.
