Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and in particular relates to a compacting device for road construction. Background Art

[0002] Road construction compaction refers to a series of mechanical compaction operations carried out during road construction to improve the stability and bearing capacity of the roadbed. These operations usually involve the use of heavy compaction hammers or other compaction equipment to repeatedly compact the soil to reduce the gaps between soil particles and increase the density and strength of the soil.

[0003] An impact roller is a type of compacting machine, also known as an impact compactor. It is a machine that continuously produces high-frequency, small-amplitude impact compaction on the ground through the rolling of a non-circular wheel surface. Compared with traditional vibratory rollers, impact rollers have the advantages of large compaction depth and high compaction effect.

[0004] There are two repetitive processes in compacting the road surface using an impact roller, namely, raising the wheel surface and hammering. These two processes are achieved by the traction of the engineering vehicle, that is, the raising and hammering of the wheel surface occur in the process of being pulled by the engineering vehicle, and the compaction hammering points on the ground after the wheel surface is raised are intermittent and discontinuous, and it takes several reciprocating cycles to complete the complete compaction of the ground, and the compaction efficiency is low.

[0005] Road rollers also have the disadvantage of being noisy, which has a great impact on the lives of surrounding residents during the construction process. Currently, many measures are taken to suppress the noise, but the most effective way is to scientifically arrange the construction time to avoid the rest time of surrounding residents, which leads to lower construction efficiency.

[0006] The present invention designs a compacting device for road construction to solve the above problems. Summary of the invention

[0007] Based on this, it is necessary to provide a compaction device for road construction to address the problems existing in the current road construction compaction equipment. The present invention drives two compaction components to rotate at a faster speed under the traction and pulling of a traction frame through two driving wheels that are always in effective contact with the road surface under the action of a counterweight, so that the distance between the compaction hammer points of the two compaction components on the road surface is effectively reduced, the density of the compaction hammer points of the compaction components on the road surface during rotation is increased, the number of times the roller repeatedly compacts the road surface is reduced, and the efficiency of the road surface compaction operation is improved. At the same time, during the process of the compaction component's rapid rotation relative to the road surface due to the traction of the traction frame, the crawler installed between the two side plates corresponding to the rotating arc part of the side plates is used to avoid the compaction component from generating sliding friction resistance with the ground after it completes a compaction hammer on the road surface, thereby further improving the rotation speed and compaction efficiency of the compaction component. When the two driving wheels in the present invention cannot rotate normally or the rotation amplitude is insufficient due to the failure of contact with the road surface, the two driving wheels can be driven to rotate normally and quickly by the transmission shaft connected to the main shaft of the engineering vehicle, so that the two driving wheels drive the two compaction components to rotate quickly with the movement of the engineering vehicle, thereby ensuring the compaction and hammering efficiency of the two compaction components on the road surface. The present invention prevents the noise generated by the two compaction components hammering the road surface from propagating far away through the first silencer component fixed to the traction frame and covered outside the two compaction components, and absorbs and weakens the noise through the water bag arranged on the inner wall of the second shell of the first silencer component, thereby achieving the purpose of eliminating or weakening the noise. The present invention inserts the second silencer component composed of many silencers into the ground to isolate the ground to be compacted and effectively absorbs the noise through the water poured into each silencer, so that the noise generated by the compaction and hammering of the ground by the compaction component in the present invention is limited to the scope of the construction site and will not be transmitted to the nearby residents' residences to affect the residents' rest. There is no need to set a specific construction time for the ground tamping construction to avoid the rest time of nearby residents, effectively extending the construction time, improving the construction efficiency, and accelerating the construction progress.

[0016] In one of the embodiments, the wheel surface of the driving wheel is densely covered with wavy anti-skid grooves circumferentially, the top of each section of the anti-skid grooves is in an inclined state, and the inclination direction of the top of each section of the anti-skid grooves is opposite to the rotation direction of the driving wheel, ensuring that the driving wheel can effectively rotate with the anti-skid grooves and the road surface under the traction of the traction frame and effectively drive the two compaction components to rotate rapidly.

[0017] In one of the embodiments, the sleeve in the compaction assembly is sleeved on the third rotating shaft, and the third rotating shaft slides around the first rotating shaft in the first sliding groove of the side wall of the first shell, and the third rotating shaft is fixed with two second discs that correspond to the compaction assembly one by one and axially abut against each other, and the second discs are connected to the side plates of the compaction assembly through tightening bolts, and the third rotating shaft is spirally connected with a locking nut that locks the two side plates of the compaction assembly to the third rotating shaft.

At the same time, during the process of the compacting assembly rotating rapidly relative to the road surface due to the traction of the traction frame, the crawler installed between the two side plates corresponding to the rotating arc part of the side plates is used to avoid the compacting assembly from generating sliding friction resistance with the ground after it completes one compaction hammering on the road surface, thereby further improving the rotation speed and compaction efficiency of the compacting assembly.

[0025] 2. When the two driving wheels in the present invention cannot rotate normally or autonomously due to failure of contact with the road surface or the rotation amplitude is insufficient, the two driving wheels can be driven to rotate normally and rapidly by the transmission shaft connected to the main shaft transmission of the engineering vehicle, so that the two driving wheels drive the two compaction assemblies to rotate rapidly with the movement of the engineering vehicle, thereby ensuring the compaction hammering efficiency of the two compaction assemblies on the road surface.

[0051] like Figure 1-15 As shown, a compacting device for road construction is used for compacting a road surface 127, comprising:

[0052] Two compaction assemblies 200 symmetrically distributed on the left and right are used for high-frequency hammering and compacting the road surface 127; the compaction assembly 200 includes two side plates symmetrically distributed on the left and right, the outer edge of the side plate 201 has three outer protrusions distributed at intervals of 120 degrees in the circumferential direction, the outer protrusions have hammering arcs 203 for compacting the road surface 127 and rotating arcs 202 for forming relative sliding with the road surface 127 after the hammering arcs 203 complete the hammering of the road surface 127, the two side plates 201 are fixedly connected by shaft sleeves 205, an impact block 206 is fixedly connected between each pair of hammering arcs 203 of the two side plates 201, and a resistance weakening structure for converting the relative sliding friction between the rotating arcs 202 and the road surface 127 into rolling friction is provided between each pair of rotating arcs 202 of the two side plates 201.

[0053] A pulling drive assembly is used to pull and drive two compaction assemblies 200 to rotate rapidly and maintain the two compaction assemblies 200 to perform high-frequency compaction hammering on the road surface 127; the pulling drive assembly includes a traction frame 101 whose front end is hinged to the engineering vehicle, and the middle part of the traction frame 101 is equipped with two left-right symmetrical driving wheels 114 through a first rotating shaft 104 that is transmission-connected to the main shaft of the engineering vehicle, and the traction frame 101 is provided with a counterweight 117 that enables the driving wheels 114 to effectively interact with the road surface 127, and the rear end of the traction frame 101 is installed with a first shell 118, and a first slide seat 120 is sliding around the first rotating shaft 104 in the first shell 118, and a third rotating shaft 121 that is transmission-connected to the first rotating shaft 104 and is used to install two compaction assemblies 200 is rotatably connected to the first slide seat 120.

[0054] The first sound insulation component 300 is used to block the noise generated by the absorbing and compacting component 200 when hammering and compacting the road surface 127 .

[0055] The second sound insulation component 400 is used to block the construction noise from propagating to the residents' residence.

[0056] The present invention drives two compacting assemblies 200 to rotate at a faster speed by two driving wheels 114 which are always in effective contact with the road surface 127 under the action of the counterweight 117 and are pulled by the traction frame 101, so that the distance between the compacting hammer points of the two compacting assemblies 200 on the road surface 127 is effectively reduced, the density of the compacting hammer points of the compacting assemblies 200 on the road surface 127 during the rotation process is increased, the number of times the roller repeatedly compacts the road surface 127 is reduced, and the efficiency of the compaction operation of the road surface 127 is improved. At the same time, during the process of the compacting assembly 200 rotating rapidly relative to the road surface 127 due to the traction of the traction frame 101, the crawler 209 installed between the two side plates 201 corresponding to the rotating arc 202 on the side plates 201 is used to avoid the compacting assembly 200 from generating sliding friction resistance with the ground after it completes a compaction hammering on the road surface 127, thereby further improving the rotation speed and compaction efficiency of the compacting assembly 200. When the two driving wheels 114 in the present invention cannot rotate normally or the rotation amplitude is insufficient due to the failure of contact with the road surface 127, the two driving wheels 114 can be driven to rotate normally and quickly by the transmission shaft 113 connected to the main shaft of the engineering vehicle, so that the two driving wheels 114 drive the two compaction assemblies 200 to rotate quickly with the movement of the engineering vehicle, thereby ensuring the compaction hammering efficiency of the two compaction assemblies 200 on the road surface 127. The present invention prevents the noise generated by the two compaction assemblies 200 hammering the road surface 127 from propagating to a distance through the first silencer assembly fixed to the traction frame 101 and covered outside the two compaction assemblies 200, and absorbs and weakens the noise through the water bag 307 arranged on the inner wall of the second shell 301 in the first silencer assembly, thereby achieving the purpose of eliminating or weakening the noise. The present invention inserts a second silencer assembly composed of many silencers into the ground to isolate the ground where compaction construction is required, and effectively absorbs noise through the water poured into each silencer, so that the noise generated by the compaction assembly 200 in the present invention compacting and hammering the ground is limited to the construction site and will not be transmitted to nearby residents' homes to affect their rest. There is no need to set a specific construction time for ground tamping construction to avoid the rest time of nearby residents, which effectively extends the construction time, improves construction efficiency, and speeds up construction progress.

[0057] In a further embodiment, Figure 1 , 2 As shown, the first rotating shaft 104 is rotatably set in the two second rotating seats 103 on the traction frame 101, and two first discs 105 corresponding to and axially abutting against the driving wheels 114 are fixedly installed on the first rotating shaft 104, and a plurality of plugs 106 evenly distributed in the circumferential direction are fixedly installed on the first disc 105, and the plugs 106 cooperate with the slots 402 on the corresponding side driving wheels 114, and a locking nut 116 is spirally connected to the first rotating shaft 104 for locking the driving wheel 114 to the first rotating shaft 104.

[0058] In a further embodiment, Figure 1 , 2 As shown, a second rotating shaft 109 perpendicular to the first rotating shaft 104 is rotatably arranged inside the two first rotating seats 102 on the traction frame 101, a second rotating shaft 109 is installed at one end of the second rotating shaft 109 with a second gear 108 meshing with the first gear 107 on the first rotating shaft 104, the other end of the second rotating shaft 109 is connected to a telescopic shaft 111 through a cross universal joint 110, and the other end of the telescopic shaft 111 is connected to a transmission shaft 113 connected to the main shaft transmission on the engineering vehicle through the cross universal joint 110.

[0059] In a further embodiment, Figure 5 As shown, the wheel surface of the driving wheel 114 is densely covered with wavy anti-skid grooves 115 in a circumferential direction, and the top of each section of the anti-skid grooves 115 is in an inclined state, and the inclination direction of the top of each section of the anti-skid grooves 115 is opposite to the rotation direction of the driving wheel 114, ensuring that the driving wheel 114 can effectively rotate with the anti-skid grooves 115 and the road surface 127 under the traction of the traction frame 101 and effectively drive the two compaction components 200 to rotate rapidly.

[0060] In a further embodiment, Figure 2 , 3 As shown in Figure 6, the sleeve 205 in the compaction component 200 is mounted on the third rotating shaft 121, and the third rotating shaft 121 slides around the first rotating shaft 104 in the first sliding groove 119 of the side wall of the first shell 118. The third rotating shaft 121 is fixed with two second discs 122 that correspond to the compaction component 200 and are axially abutted against each other. The second discs 122 are connected to the side plates 201 of the compaction component 200 through tightening bolts. The third rotating shaft 121 is spirally connected with a locking nut 116 that locks the two side plates 201 of the compaction component 200 to the third rotating shaft 121.

[0061] In a further embodiment, Figure 3 As shown, two left-right symmetrical first sprockets 124 are fixedly mounted on the third rotating shaft 121, and the first sprockets 124 are transmission-connected to the second sprocket fixedly mounted on the first rotating shaft 104 via a chain 125. The transmission ratio between the first sprocket 124 and the second sprocket is greater than 1, thereby ensuring that the rotation speed of the compaction component 200 is greater than the rotation speed of the driving wheel 114, thereby increasing the density of compaction hammer points of the compaction component 200 on the road surface 127 during rotation.

[0062] In a further embodiment, Fig.10 , 13As shown in Figures 15, the resistance reduction structure includes a plurality of first belt rollers 207 and two second belt rollers 214. The plurality of first belt rollers 207 are installed between each pair of rotating arcs 202 of two side plates 201 in the compaction assembly 200 through a fixed first roller shaft 212. The first belt rollers 207 are evenly arranged along the rotating arcs 202. The two second belt rollers 214 are installed between each pair of rotating arcs 202 of two side plates 201 in the compaction assembly 200 through a fixed second roller shaft 215. The first belt rollers 207 and the second belt rollers 214 are wound with tracks 209. The limiting strip 210 in the middle of the track 209 cooperates with the middle annular groove 208 of the first belt roller 207 and the second belt roller 214. The winding outer diameter of the track 209 on the first belt roller 207 is larger than the outer diameter of the rotating arc portion 202, ensuring that the rotating arc portion 202 of the side plate 201 in the compaction component 200 will not come into contact with the road surface 127 after the impact block 206 between the hammering arc portion 203 completes the hammering of the road surface 127, thereby eliminating the sliding friction between the rotating arc portion 202 of the side plate 201 and the road surface 127 caused by the rotation speed of the compaction component 200 being faster than the driving wheel 114.

[0063] In a further embodiment, Figure 4 , 11As shown in , 12 and 13, the resistance weakening structure includes a plurality of first belt rollers 207 and two second belt rollers 214, wherein the plurality of first belt rollers 207 are installed between each pair of rotating arc portions 202 of two side plates 201 in the compaction assembly 200 through a first roller shaft 212, and the first belt rollers 207 are evenly arranged along the rotating arc portions 202, and the two second belt rollers 214 are installed between each pair of rotating arc portions 202 of two side plates 201 in the compaction assembly 200 through a second roller shaft 215, and second slide seats 213 are rotatably provided at both ends of the first roller shaft 212 or the second roller shaft 215, and the second slide seat 213 slides in the second slide groove 204 on the side plate 201 along the radial direction of the rotating arc portion 202, and the second slide seat 213 and the second slide groove 204 are between them. The guide block and guide groove cooperate, and the first belt roller 207 and the second belt roller 214 between each pair of rotating arc portions 202 of the two side plates 201 in the compaction component 200 are wound with a track 209, and the limiting strip 210 in the middle of the track 209 cooperates with the middle annular groove 208 of the first belt roller 207 and the second belt roller 214, and the winding outer diameter of the track 209 on the first belt roller 207 is larger than the outer diameter of the rotating arc portion 202, ensuring that the rotating arc portion 202 of the side plate 201 in the compaction component 200 will not come into contact with the road surface 127 after the impact block 206 between the hammering arc portion 203 completes the hammering of the road surface 127, thereby eliminating the sliding friction between the rotating arc portion 202 of the side plate 201 and the road surface 127 caused by the rotation speed of the compaction component 200 being faster than the driving wheel 114. A reinforcing roller 211 is installed between each pair of rotating arc portions 202 of the two side plates 201 in the compaction assembly 200 via a fixed third roller shaft 216. The reinforcing roller 211 is in radial contact with the first belt roller 207 so that the force exerted by the road surface 127 on the first belt roller 207 is transmitted to the reinforcing roller 211 on the third roller shaft 216 with higher strength, thereby preventing the first roller shaft 212 on which the first belt roller 207 is located from being deformed after long-term use.

[0064] In a further embodiment, Figure 2 , 4 As shown in , 14, the first sound insulation component 300 includes a second shell 301 with an opening at the lower end, the second shell 301 is covered on the outside of the two compaction components 200 and is fixed to the traction frame 101 through a plurality of support rods 308, the front end of the second shell 301 is provided with two movable grooves 306 that cooperate with the chain 125, the front lower end of the front side of the second shell 301 is hinged with a front baffle 304 that cooperates with the road surface 127, the rear lower end of the second shell 301 is hinged with a rear baffle 305 that cooperates with the road surface 127, both sides of the lower end of the second shell 301 are provided with slats 302 that are inserted into the soil of the road surface 127, the front end of the slats 302 has a downward pressing inclined surface 303, the inner wall of the second shell 301 is provided with a water bag 307, and the water bag 307 is composed of a plurality of small water cavities.

[0065] In a further embodiment, Figure 7 , 8 As shown in Figure 9, the second sound insulation assembly 400 includes a plurality of sound insulation tubes 401, which are connected in sequence and arranged around the ground where the construction is to be carried out. The lower end of the sound insulation tube 401 has a cone tip for easy insertion into the soil of the road surface 127. The sound insulation tube 401 is filled with water. The outer wall of the sound insulation tube 401 has a slot 402, and the slots 402 of adjacent sound insulation tubes 401 are plugged in and matched along their axial direction.

[0066] The operation process of the present invention is as follows:

[0067] The two slats 302 in the first sound insulation component 300 are respectively inserted into the soil of the road surface 127, and the front baffle 304 and the rear baffle 305 at the front and rear ends of the second shell 301 are respectively in contact with the road surface 127 and swing back a certain distance, so that a sealed sound insulation space for the two compaction components 200 is formed between the second shell 301 and the road surface 127.

[0068] When the counterweight 117 is sufficient to ensure that the anti-skid grooves 115 on the two driving wheels 114 have sufficient grip on the road surface 127, as the engineering vehicle moves forward, the traction frame 101 drives the two driving wheels 114 to rotate under the traction of the engineering vehicle, and the two driving wheels 114 drive the first rotating shaft 104 to rotate synchronously. The first rotating shaft 104 drives the third rotating shaft 121 to rotate at a faster speed through the two second sprockets, the chain 125 and the first sprocket 124. The third rotating shaft 121 drives the two compaction assemblies 200 to rotate synchronously. During the rotation of the two compaction assemblies 200, the compaction assembly 200 will drive the third rotating shaft 121 to reciprocate around the first rotating shaft 104 due to its structure. The third rotating shaft 121 drives the first slide seat 120 to slide back and forth around the first rotating shaft 104 in the first shell 118.

[0069] When the traction frame 101 pulls the two compaction assemblies 200 to rotate forward, the slats 302 at the lower end of the second shell 301 in the first sound insulation assembly 300, under the action of the downward pressing slope 303 at its front end and the soil, enable the second shell 301 to always maintain a spatial seal for the two compaction assemblies 200, ensuring that the noise generated by the two compaction assemblies 200 when compacting and hammering the road surface 127 is isolated and effectively absorbed by the water in the water bag 307 on the inner wall of the second shell 301.

[0070] During the rotation of the two compaction assemblies 200, the hammer arc 203 at the location of the impact block 206 in the compaction assembly 200 is driven by the impact block 206 to drop suddenly from the adjacent rotating arc 202 to hammer and compact the road surface 127. Since the rotation speed of the compaction assembly 200 is greater than the rotation speed of the driving wheel 114 and the maximum outer diameter of the compaction assembly 200 is greater than the outer diameter of the driving wheel 114, the rotating arc 202 in the compaction assembly 200 will slide relative to the road surface 127 after the hammer arc 203 completes the hammering and compaction of the road surface 127. The outer diameter of is larger than the outer diameter of the rotating arc portion 202 on the side plate 201, so that the rotating arc portion 202 of the two side plates 201 in the compaction component 200 will not contact the road surface 127 after the hammering arc portion 203 completes the hammering and compaction of the road surface 127. The track 209 will drive the corresponding set of second belt rollers 214 and the first belt roller 207 to rotate due to the rapid rotation of the compaction component 200, and there will be no relative sliding between the track 209 and the road surface 127, thereby avoiding the generation of sliding friction resistance between the side plate 201 of the compaction component 200 and the road surface 127, thereby improving the rotation efficiency of the compaction component 200 and the compaction hammering efficiency of the road surface 127.

[0071] When the counterweight 117 is insufficient to ensure that the anti-skid grooves 115 on the two driving wheels 114 have sufficient grip on the road surface 127, a connection is established between the transmission shaft 113 and the main shaft on the engineering vehicle. As the engineering vehicle moves forward, the traction frame 101 drives the two driving wheels 114 to rotate under the traction of the engineering vehicle. At the same time, the main shaft on the engineering vehicle drives the first rotating shaft 104 to rotate through the transmission shaft 113, the cross universal joint 110, the telescopic rod and the second rotating shaft 109, so that the first rotating shaft 104 drives the two compaction assemblies 200 to rotate effectively and quickly through the two second sprockets, the chain 125 and the first sprocket 124, and the third rotating shaft 121, thereby ensuring that the two compaction assemblies 200 perform high-frequency and effective hammer compaction on the road surface 127.

[0072] Before the road surface 127 or the ground is hammered and compacted, the second sound insulation component 400 is used to form a fence around the road surface 127 or the ground to be hammered and compacted, so that each sound insulation tube 401 is inserted into the soil of the road surface 127 or the ground to a certain depth, so that the slots 402 of adjacent sound insulation tubes 401 are plugged into each other to complete the connection of adjacent sound insulation tubes 401. After the sound insulation tubes 401 are inserted into the soil, water is poured into the sound insulation tubes 401. When the two compaction components 200 hammer and compact the ground or road surface 127 under the traction of the engineering vehicle, the fundamental cause of the noise, that is, the vibration generated by the two compaction components 200 hammering and compacting the road surface 127, will be effectively absorbed by the water in the sound insulation tube 401, thereby blocking the noise generated in the process of hammering and compacting the road surface 127 or the ground of the present invention from being transmitted to nearby residents' homes. There is no need to set a specific construction time for the ground tamping construction to avoid the rest time of nearby residents, which effectively extends the construction time, improves the construction efficiency, and speeds up the construction progress.
