Detailed Description
For a further understanding of the present invention, the present invention will be described in detail with reference to the drawings.
In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As mentioned in the background art, the existing roadbed compacting device is lack of effective support to the guard edge channel steel, so that the problem that cracks and even collapse are easy to occur when the roadbed edge position is rolled is caused. In the prior art, an inclined support is additionally arranged on the outer side of the guard channel steel to overcome the outward extrusion force of the guard channel steel, so that the guard channel steel is prevented from deviating. However, in the actual construction process, in order to facilitate the dismantling operation of the later-stage inclined support, the supporting point of the inclined support cannot be reinforced with concrete. Therefore, the inclined support lacks stable stress points, so that the supporting force of the guard channel steel is greatly reduced, and the guard channel steel is difficult to completely ensure that the guard channel steel does not deviate.
The problem that the inclined support lacks a stable stress point and cannot provide stable support for the edge protection channel steel alone is solved, and the optimal scheme can be thought that the support plate is directly fixed on the road roller, so that a stable stress point can be formed and used for supporting from the side face of the edge protection channel steel. The road surface to be compacted is not an ideal straight line, but is bent, and the road roller is deviated in the actual running process, so that the position of the supporting plate is changed continuously, the supporting plate is separated from the guard edge channel steel easily, and the original supporting effect is lost. Therefore, this solution cannot be applied in practical construction.
The invention provides a vibration compaction device capable of improving subgrade filling edge collapse and a construction method, and aims to solve the problem that a safe edge channel steel cannot be stably supported when a rolling roller presses the edge of a roadbed, so that the safe edge channel steel is easy to deviate to cause subgrade edge collapse, and meanwhile, the stable supporting effect can be still provided for the safe edge channel steel when the running direction of a road roller deviates.
The invention is further described below in connection with specific embodiments.
As shown in fig. 1, a vibratory compaction apparatus for improving edge collapse of a subgrade filling according to this embodiment includes a roller and a binder mechanism 200. The road roller is basically identical to the structure of the prior art, and mainly comprises a roller body 100, a mounting frame 110 arranged at the front of the roller body 100, and a roller 120 arranged in the mounting frame 110. A camera 130 may be added to the front of the mounting frame 110 to facilitate real-time monitoring of the road conditions by the driver.
The guard mechanism 200 is installed on the installation frame 110, and is used for laterally supporting the guard channel steel at the edge position of the roadbed, so that when the edge position of the roadbed is crushed by the crushing roller 120, the applied pressure can cause the guard channel steel to move, and further, the base layer and the subbase structure at the edge of the soil layer lose support and collapse.
Specifically, referring to fig. 2, the edge guard mechanism 200 includes a side support member 220 and a lifting member 210 for driving the side support member 220 to lift. Wherein the elevation member 210 is provided on a side wall of the installation frame 110 at one side in the axial direction of the platen roller 120. The lifting member 210 may be configured to lift the side supporting member 220 using a conventional technology, such as a cylinder, an oil cylinder, an electric push rod, or other structures.
As shown in fig. 6, the side support part 220 includes a main support block 221 connected to the output end of the elevating part 210, and a receiving space for the guard channel is formed between the main support block 221 and the end of the laminating roller 120. When the roller 120 rolls the edge of the subgrade, the lifting member 210 drives the main supporting block 221 to descend, and supports the outer side of the guard channel steel, so as to prevent collapse of the edge of the subgrade due to stress deflection of the guard channel steel.
Further, a first mounting hole 2211 is formed in the main supporting block 221, an auxiliary supporting block 222 is slidably disposed in the first mounting hole 2211, and the auxiliary supporting block 222 is connected to a first elastic member 223. The auxiliary support block 222 is compressed into the first mounting hole 2211 when the main support block 221 is operated normally. At this time, the main supporting block 221 is abutted against the outer side of the guard channel, thereby providing a larger supporting surface.
When the apparatus is moved, the roller 120 is deviated to the outside of the roadbed due to road surface or driving, etc. As the roller 120 is continuously deflected outward, the main supporting block 221 is gradually separated from the binder channel, thereby losing the supporting effect. At this time, the auxiliary supporting block 222 is ejected from the first mounting hole 2211 by the first elastic member 223, and temporarily supports the edge guard channel. Thereby avoiding the risk of movement of the guard channel during the time when the main support block 221 loses its support effect. When the rolling position of the roller 120 is restored to normal, the auxiliary supporting block 222 is compressed into the first mounting hole 2211, and the main supporting block 221 provides support for the guard channel.
In the present embodiment, the paper surface direction of fig. 6 is the reference. The first mounting hole 2211 is a through hole, and two through holes are arranged left and right. A positioning plate 224 is provided at a position of the first mounting hole 2211 on a side of the main support block 221 remote from the mounting frame 110. Meanwhile, a guide rod 225 and a positioning rod 226 are provided at a side of the auxiliary supporting block 222 facing the positioning plate 224. The first elastic member 223 is sleeved on the positioning rod 226, and is limited between the positioning plate 224 and a stop block at the end of the positioning rod 226.
Preferably, two guide rods 225 are disposed up and down, and a positioning rod 226 is disposed between the two guide rods 225. Of course, a guiding hole is provided at the corresponding position on the positioning plate 224 for the guiding rod 225 and the positioning rod 226 to pass through freely.
In some embodiments, when the apparatus is moved, the roller 120 is biased toward the inside of the roadbed due to road surface or driving, etc. At this time, smooth movement of the laminating roller 120 is restricted due to the stopper action of the edge guard channel on the main supporting block 221. At the same time, the main supporting block 221 is subjected to a larger inverse pressing force, so that the damage of the connection point between the lifting member 210 and the mounting frame 110 and the main supporting block 221 is easily accelerated, and even the breakage of the connection point is caused. For this reason, in the present embodiment, a transition member 230 is disposed between the lifting member 210 and the main supporting block 221 to reduce the damage of the connection point caused by the excessive compression strength.
Specifically, referring to fig. 7, the transition member 230 includes a connection frame 231 and a slider 232 slidably disposed within the connection frame 231. Wherein the connection frame 231 is disposed at the top of the main supporting block 221, and the output end of the elevation member 210 is connected with the top of the sliding block 232. Meanwhile, the sliding block 232 is connected with a second elastic member 235. When the device is deviated to the inner side of the roadbed, the lifting part 210 can drive the sliding block 232 to slide in the connecting frame 231 towards the direction of the mounting frame 110, so that the excessive reaction force on the main supporting block 221 can be effectively reduced. When the device returns to the normal position, the sliding block 232 returns to the original position under the action of the second elastic member 235, so that the supporting effect of the main supporting block 221 on the guard channel is not affected.
Further, a support column 233 is additionally arranged in the connection frame 231, and the sliding block 232 is sleeved on the support column 233, so that stability of the sliding block 232 in the sliding process is improved. Meanwhile, the second elastic member 235 is also sleeved on the supporting column 233 and is limited between the sliding block 232 and the inner wall of the connecting frame 231 near one end of the mounting frame 110.
As shown in fig. 4, in some embodiments, the upper surface of the support column 233 is provided with a series of limiting grooves 2331 spaced apart along its length (i.e., the sliding direction of the sliding block 232). Meanwhile, a limiting block 234 which can be mutually clamped with the limiting groove 2331 is arranged on the side face of the sliding block 232, so that the stability of the main supporting block 221 on the supporting of the guard channel steel is ensured.
Of course, the engagement between the limiting block 234 and the limiting groove 2331 needs to ensure that the rolling roller 120 performs a limiting function on the sliding block 232 when rolling normally at the edge, and on the other hand, the sliding block 232 can smoothly move and reset when the device deviates to the inner side of the roadbed, so that the main supporting block 221 maintains the original position. For this reason, in the present embodiment, the stopper 234 is made of an elastic material, such as spring steel, stainless steel, or an alloy material, which is not shown here. Meanwhile, an inclined surface is formed on the side of the stopper 234 away from the mounting frame 110. Of course, the limit groove 2331 is also provided with an inclined surface which is matched with the limit groove.
When the device is offset, the acting force born by the limiting block 234 is larger, so that the limiting block 234 is extruded and deformed in the limiting groove 2331, and is separated from the limiting groove 2331, and the movement of the sliding block 232 is realized. When the stopper 234 is reset under the action force of the second elastic member 235, the action force of the second elastic member 235 is far smaller than the driving force generated when the device is biased, but due to the inclined surface, the stopper 234 can be disengaged from the limiting groove 2331.
In some embodiments, the outside of the binding channel may incorporate a diagonal brace, and the main support block 221 may interfere with the diagonal brace during movement with the roller body 100. For this purpose, in the present embodiment, the output end of the lifting member 210 is hinged to the sliding block 232, and a notch 2213 is formed at the bottom of the main supporting block 221 near the middle. When the main support block 221 moves to the inclined support, the lifting component 210 is utilized to drive the main support block 221 to move upwards, and when the notch 2213 is clamped at the top of the inclined support, the main support block 221 can incline along the hinging point adaptively, so that the main support block 221 can be prevented from being blocked. In addition, to ensure the stability of the support of the auxiliary support blocks 222, a first mounting hole 2211 is formed on each of the main support blocks 221 at both sides of the slot 2213, and each of the first mounting holes 2211 is internally provided with an auxiliary support block 222.
According to the vibrating compaction device capable of improving the edge collapse of the roadbed filling, through the arrangement of the main supporting blocks 221 and the auxiliary supporting blocks 222, although the roller 120 can be ensured to be capable of effectively supporting the edge protection channel steel all the time when the roller 120 is deflected. But when the roller 120 is shifted toward the inside of the road surface, the edge of the roadbed is not crushed any more, resulting in insufficient compactness of the roadbed at that portion, leaving a quality defect. For this, in the present embodiment, a second mounting hole 2212 is also formed in the main support block 221, and a pressing roller assembly 240 is disposed in the second mounting hole 2212. The press roll assembly 240 temporarily compacts the edge of the road bed as the laminating roll 120 is moved away from the edge of the road bed.
Referring to fig. 3 and 8, the second mounting hole 2212 is opened above the first mounting hole 2211. The press roller assembly 240 includes a positioning frame 241 and a press roller 242. The positioning frame 241 is a U-shaped frame integrally, and a pressing wheel 242 is rotatably connected in the U-shaped frame through a rotating shaft. The top of the positioning frame 241 is provided with a protruding block 244, and the protruding block 244 is provided with a first sliding groove 2441. The first sliding groove 2441 is integrally a high-low groove and comprises a high groove section, a low groove section and a transition section connected with the high groove section and the low groove section.
The first sliding groove 2441 is provided with a sliding rod 245 connected with the main supporting block 221. Meanwhile, the positioning frame 241 is connected with the sliding block 232 through the connecting rod 243. When the sliding block 232 moves, the positioning frame 241 is driven to move by the connecting rod 243, so that the sliding rod 245 is matched with the high and low groove sections of the first sliding groove 2441 in turn, so as to realize lifting of the positioning frame 241, and further drive the pinch roller 242 to lift.
In this embodiment, the first sliding groove 2441 is formed on the sidewall of the bump 244 and is a through groove. Both ends of the sliding rod 245 extending out of the first sliding groove 2441 are connected with a first fixed block 246, and the top of the first fixed block 246 is connected with the inner top wall of the second mounting hole 2212.
The link 243 includes a first link 2431 and a second link 2432 that are coupled to each other and are slidable up and down. Wherein, first connecting rod 2431, second connecting rod 2432 are whole L type structure. One end of the first connecting rod 2431 passes through the connecting frame 231 to be connected with the sliding block 232, the other end of the first connecting rod 2431 is clamped into the jack of the second connecting rod 2432 and can freely lift, and the other end of the second connecting rod 2432 is connected with the positioning frame 241. Through the mutual cooperation of the first connecting rod 2431 and the second connecting rod 2432, the sliding block 232 can drive the positioning frame 241 to horizontally move, and the up-and-down movement of the positioning frame 241 can not be prevented.
As shown in fig. 5, in some embodiments, a second sliding groove 2442 is further formed at the top of the bump 244, and a sliding frame 247 is slidably disposed in the second sliding groove 2442. The sliding frame 247 is provided with a second fixing block 248, and the top of the second fixing block 248 is connected to the inner top wall of the second mounting hole 2212. By the mutual cooperation of the second fixed block 248 and the sliding frame 247, the stability of the positioning frame 241 during the movement can be further ensured.
In some embodiments, the compaction roller 120 is further connected with an adjusting component for adjusting the compaction pressure and the vibration frequency of the compaction roller 120 to adapt to the vibration compaction requirements of soil layers with different characteristics.
Specifically, referring to fig. 9, the adjustment assembly includes a support shaft 140 disposed within the laminating roller 120, the support shaft 140 being provided with a plurality of eccentric blocks 150 spaced apart along an axial direction thereof, and each eccentric block 150 being provided with a respective driving source 160. Wherein, the driving source 160 and the eccentric block 150 can be sleeved on the supporting shaft 140. Preferably, the driving source 160 is a hollow motor, and an output end of the hollow motor is connected to the eccentric mass 150. The eccentric block 150 is driven to rotate by the hollow motor, and when the eccentric block 150 rotates, the roller 120 can vibrate, so that the roller 120 can apply enough pressure to the ground. Meanwhile, the number of rotations of the eccentric block 150 can be controlled according to the pressure required to be applied to the ground, so that the pressure generated by the laminating roller 120 can be adjusted. In addition, the vibration frequency of the platen roller 120 may be adjusted by controlling the rotational speed of the hollow motor.
In this embodiment, 5 eccentric blocks 150 and driving sources 160 are provided, and for convenience of description, the eccentric blocks 150 are numbered 1, 2, 3,4, and 5 in order from left to right, based on the paper surface direction of fig. 9. The eccentric blocks 150 of 1-5 can automatically adjust different vibration frequencies and pressures according to the grading characteristics of pavement materials, and the specific working states are as follows:
The first state is that the eccentric blocks 150 of the numbers 1, 3 and 5 are rotated in daily use, the rolling force is relatively uniform, and the compaction machine is suitable for compaction of most soil layers;
2, the eccentric blocks 150 of the No. 4 are rotated, so that the method is suitable for scenes in which soil layers are softer;
in the third state, all eccentric blocks 150 rotate together, and are suitable for a hard soil layer;
The eccentric blocks 150 of the No. 1 and the No. 5 are rotated, so that the method is suitable for compacting the edge position of the road foundation soil layer;
According to the 4 states, the pressure is divided into normal state, pressure is reduced, pressure is increased and pressure at a special edge position is increased, so that the pressure required to be applied by soil compaction in most cases can be adapted. The driving source 160 and its control module are all in the prior art. For example, the driving source 160 may be a Y-series hollow shaft motor, which is a relatively common three-phase asynchronous motor, and has the advantages of high efficiency, energy saving, low noise, small vibration and the like. The center of the eccentric block 150 is provided with a hollow shaft which is convenient to connect with the eccentric block 150 so as to realize stable rotation of the eccentric block 150. The control module model can be Siemens S7-200SMART, which is a small PLC controller with rich instruction set and powerful communication function.
The concrete construction method of the vibrating compaction device capable of improving the collapse of the filling edge of the roadbed in the embodiment is as follows:
firstly, sundries, garbage, loose soil and the like in a construction site are removed, a new road is set, the center line and the side line of the road are lofted according to design requirements, and level points are set to provide a reference for subsequent construction.
When the pavement soil layer is crushed, the condition of the pavement is monitored through the camera 130, and the vibration pressure of the crushing roller 120 is adaptively adjusted through the adjusting assembly.
When rolling the soil layer edge, support the location through safe edge mechanism 200 to the safe edge channel-section steel on road surface, specifically:
When the roller 120 rolls the edge of the soil layer of the road, the main supporting block 221 contacts with the guard channel steel at the roadside, so that the guard channel steel can be supported by the main supporting block 221, and the situation that the guard channel steel moves due to the pressure applied by the roller 120 during rolling and the edge of the soil layer of the road is not supported is avoided. Meanwhile, as the roller 120 moves, the main supporting block 221 may continuously support the guard channel.
When the main supporting block 221 approaches to the inclined support of the guard channel steel, the lifting component 210 drives the main supporting block 221 to move upwards, so that the main supporting block 221 can move upwards when contacting with the inclined support, the notch 2213 at the bottom of the main supporting block 221 is clamped at the top of the inclined support, and the main supporting block 221 can incline adaptively along with the movement of the grinding roller 120, so that the main supporting block 221 is prevented from being blocked. When the main supporting block 221 inclines for a certain angle, the main supporting block 221 can be driven to move upwards, so that the notch 2213 at the bottom of the main supporting block 221 is separated from the inclined support, and after crossing the inclined support, the main supporting block 221 is driven to reset downwards.
When the device is in driving, the roller 120 deflects to the outside of the road due to improper driving of a driver or road surface, and the main supporting block 221 is separated from the safe edge channel steel along with the outward deflection of the roller 120, and the auxiliary supporting block 222 is pushed out by the first elastic piece 223 and contacted with the safe edge channel steel, so that the safe edge channel steel can be temporarily supported, and the situation that the safe edge channel steel is displaced due to the loss of support in the separation period of the main supporting block 221 and the safe edge channel steel is avoided.
When the apparatus is shifted to the inside of the road due to improper driving of a driver or road surface during traveling of the apparatus. Since the main supporting block 221 is blocked by the guard channel and cannot move, the sliding block 232 moves within the connecting frame 231, so that the main supporting block 221 is always guaranteed to be in the current position and continuously supports the guard channel.
Meanwhile, since the rolling roller 120 is biased toward the inside of the road, the edge position of the road soil layer cannot be rolled. When the sliding block 232 moves, the positioning frame 241 is driven by the connecting rod 243 to move, when the positioning frame 241 moves, the sliding rod 245 enters the high groove section from the low groove section of the first sliding groove 2441, and at the moment, the positioning frame 241 moves downwards under the cooperation of the sliding rod 241 and the high groove section and drives the pressing wheel 242 to move downwards, so that the pressing wheel 242 can be contacted with the top of the edge of the road soil layer and generate pressure on the top of the edge of the road soil layer. Therefore, the edge of the road soil layer can be temporarily rolled, and the raised soil on the edge surface of the road soil layer is flattened, so that the condition that the edge position of the road soil layer is leaked when the rolling roller 120 is deviated to the inner side of the road is avoided.
It should be noted that, when the driver finds that the rolling roller 120 is deviated, the rolling roller 120 is quickly adjusted, so as to avoid the situation that the edge of the road soil layer cannot be fully rolled due to too long use time of the pressing roller 242. Of course, techniques may be used to monitor and alert the deflection of the laminating roller 120. For example, a position sensor is provided on the mounting frame 110 and a buzzer is provided to prompt the operator for timely adjustment.
According to the vibrating compaction device capable of improving the edge collapse of the roadbed filling, through the arrangement of the edge protection mechanism 200, the continuity of supporting of the edge protection channel steel can be effectively ensured by using the alternate supporting of the main supporting blocks 221 and the auxiliary supporting blocks 222, and the supporting effect is ensured. Meanwhile, when the roller 120 cannot grind the soil layer edge position due to the offset, the roller assembly 240 can temporarily grind the road soil layer edge position, so that the risk of leakage of the road soil layer edge caused by inward movement of the roller 120 can be effectively avoided.
The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
