Description

All-in-one port hall repair vehicle

The present invention relates to a porthole repair vehicle, and more particularly, to an all-in-one porthole repair vehicle in which all equipment necessary for the porthole repair is compactly installed so that the entire process of the porthole repair may be performed in one vehicle.

Ascon pavement causes local small holes (hereinafter referred to as "port holes") on the pavement surface due to lack of voltage during construction, poor quality of the mixture, poor drainage structure, or natural environmental factors. It is a big threat.

In general, the pothole repair work is carried out by crushing the potholes to a certain size, removing the debris, spraying them into the ascon porthole, and then applying the ascon into the pothole. The rollers are made in the order of flattening and compacting.

However, such repair work requires a lot of manpower, time, and money because many equipments such as ascon transportation vehicles, road cleaning vehicles, ascon spraying vehicles, roller vehicles, etc. move together and are alternately performed.

In some road repairs, only a temporary repair is performed to repack the asphalt concrete after cleaning only the shredding holes. Such temporary repair work may not last long and may cause continuous damage. Therefore, there is an urgent need for improvement.

The small third horizontal boom (not shown) is shown to be configured in such a way that it is drawn out in turn. However, the number and shape of the boom may be configured differently from FIG. In addition, although the third horizontal boom is not shown in FIG. 2, the third horizontal boom is embedded in the second horizontal boom 33.

The upright rotary arm 31 is provided in the center of the width direction of the body 11 of the moving body 10, as shown in FIG. Therefore, when changing the direction of movement of the moving body not only does not move the weight of the moving body 10 to any one, but also when the mobile body 10 is arranged so that the port hole portion is in the front center of the mobile body 10, the mobile body 10 All work can be done without changing the position of the work quickly and the work stability is also improved.

In particular, while the position of the front mechanism portion 20 is provided with the shredding drum 221 is placed in front of the moving body 10, the front mechanism portion 20 and the upper mechanism portion 30 can work alternately at the same position without any interference with each other. However, in the present invention, the control unit controls the upper mechanism unit 30 by using a plurality of sensors so that the operation of the front mechanism unit 20 and the upper mechanism unit 30 can be more thoroughly prevented. This will be described later in detail.

As shown in FIG. 1, a suspension arm 35 is installed at an end portion of the third horizontal boom (not shown). For reference, the third horizontal boom is not shown because it is inserted into the second horizontal boom 33. The suspension arm 35 is provided with a first vertical boom 36 supported by the suspension arm 35 and second and third vertical booms (not shown) which are pulled out or inserted from the first vertical boom 36 to the road surface. The compaction roller 37 and the asphalt concrete applicator 38 can be approached.

Ascon supply unit 40 is installed on the upper body 11, the ascon is embedded, and delivers the ascon to the upper mechanism unit (30).

The debris collection unit 50 includes a collection tank 51 installed above the body 11 and collecting and collecting the debris collected by the suction device 23, and a dump actuator 52 installed below the collection tank. .

The control unit includes a lower camera (not shown) installed at a predetermined point of the front camera 61 and the shredding drum 221 installed in front of the cabin 12, a plurality of sensors and the cabin provided in the upper mechanism part 12. It consists of a control unit (not shown) installed.

As shown in FIG. 5, the front mechanism part 20 horizontally varies the asphalt crushing drum 221 installed in the front of the cabin 12 and the crushing drum 221 vertically and horizontally in front of the movable body 10. It consists of the mechanism 21, the suction mechanism which sucks up the asphalt crushed material by the crushing drum 221, and the connecting frame 25 which fixedly connects the horizontal variable mechanism 21 to the front of the cabin 12.

Here, the horizontal variable mechanism is connected to the front of the cabin 12, as shown in Figure 6a and 6b is installed horizontally along the width direction of the cabin 12, the horizontal rail 212 and the horizontal rail 212 In accordance with the left and right transverse arms 211 which are variable to the left and right of the cabin 12, the inner boom is connected to the front end of the left and right transverse arms 211 by the hinge shaft 214, the inner boom with a small diameter inside the large boom 216 217 is made up of a front boom configured to be retractably inserted.

The drum housing 229 is coupled to the end of the inner boom 217 as shown in Figure 8b and the shredding drum 221 is rotatably installed therein.

Since the drum housing 229 and the

front booms

216 and 217 are all connected to the left and right cross arms 211 in turn, the

front booms

216 and 217 and the drum housing 229 are integrated together when the left and right cross arms 211 are changed to the left and right. It is variable from side to side. Further, in the

front booms

216 and 217, the second boom 217 is variable, so that the drum housing 229 can be moved at any point in the horizontal direction.

On the other hand, in the front camera 61, a horizontal center line is formed on the screen (not shown), and the vehicle is moved forward or backward so that the center of the road breakage part is located at the horizontal center line, and then the horizontal center line is set to be specified. , The controller (not shown) controls the withdrawal lengths of the

front booms

216 and 217 to match the set horizontal center line, thereby placing the shredding drum 221 on the longitudinal center line.

At this time, a longitudinal center line is formed on the screen (not shown) in the downward camera (not shown), and the left and right cross arms 211 are aligned along the horizontal rail 212 so that the center of the road breakage part is located at the longitudinal center line. After setting, the longitudinal center line is set to be the center of the port hole, the control unit can automatically control to match the specified longitudinal center line when the left and right transverse arms 211 deviate from the longitudinal center line.

At this time, when the shredding drum 221 is located at the intersection of the set transverse center line and the longitudinal center line, and sets the contact point when falling down and contacting the road failure site, the control unit is the shredding drum 221 or the compaction roller. The position of 37 is controlled to be automatically moved to the set zero point.

Therefore, even if the shredding drum 221 is changed in another direction as needed, when the control unit commands the front mechanism part 20, the front mechanism part 20 immediately moves the shredding drum 221 to the zero coordinate so that the work can be quickly performed. Can be prepared.

On the other hand, in the upper mechanism part 30, the plurality of horizontal booms are the first horizontal boom 32 having a fixed distance from the upright rotating arm 31 and the second horizontal boom drawn out from the end of the first horizontal boom 32. And a third horizontal boom (not shown) drawn out from the end of the second horizontal boom 33.

At this time, the stroke sensor 62 is provided in the end part of the upright rotary arm 31 of the 1st horizontal boom 32, and the edge part of a 3rd horizontal boom (not shown), respectively, and according to the distance between the stroke sensors 62, Two boom total lead-out lengths are measured by the stroke sensor 62.

In addition, as shown in FIG. 2, a rotation angle sensor 63 is installed at a predetermined position of the upright rotation arm 31 so that the measured value of the stroke sensor 62 and the measured value of the rotation angle sensor 63 are controlled by the controller. As received, the control unit can capture the position of the suspension arm 35 and compaction roller 37 in real time.

In this case, the occupied space coordinate information of the cabin 12 is previously input to the controller, and when the upright rotation arm 31 is rotated, it is determined according to the measured values of the stroke sensor 62 and the rotation angle sensor 63 which are received in real time. The positional information of the suspension arm 35 and the compaction roller 37 is calculated.

Since the position information is transmitted to the control unit in real time, interference between the cabin 12 and the compaction roller 37 may be prevented when the suspension arm 35 and the compaction roller 37 are moved forward or backward of the cabin 12. It is possible for the control part to adjust the withdrawal length of the second or third horizontal boom.

In addition, the controller controls the rotational speed of the upright rotary arm 31 to prevent interference between the cabin 12 and the suspension arm 35 during the withdrawal time of the second or third horizontal boom. Because, even if the control unit commands the sunrise to the second or third horizontal boom (not shown) to the specified length to prevent the interference, if the rotational speed of the upright rotary arm 31 is too fast, the cabin 12 and This is because interference or collision between the compaction rollers 37 may occur.

On the other hand, the basket 39 toward the ascon supply unit 40 is installed behind the compaction roller 37, as shown in FIG. The basket 39 receives the ascon from the ascon supply unit 40 to be applied at the point where the road breakage part is crushed by the crushing drum 221. The conveyed ascon is applied by pouring the compaction roller 37 and the basket 39 into the fracture site by the movement of the basket tilting actuator 391 from the rear of the cabin 12 to the front of the cabin 12.

In this case, the amount of ascon supplied from the ascon supply unit 40 to the basket 39 is set to correspond to the space of the unit volume formed by the control unit crushing the crushing drum 221 and is automatically calculated as much as the crushing space.

That is, if the amount of ascon coating required per unit crushing volume is x, when the actual crushing volume is expressed as 'ax', the ascon supply unit 40 automatically loads the ascon corresponding to the a quantity of x amount in the basket 39. Ascon supply is made. Such ascone supply can be automatically determined by checking the operating time of the shredding drum 221 or the rotation speed of the shredding drum 221.

On the other hand, when the work to compact the application site with the compaction roller 37 after the application of ascon, it may be necessary to vary the pressure depending on the road site. Alternatively, the road surface may be considered to be flattened only when the pressure of either side is increased.

In this case, when the compaction roller 37 is maintained only horizontally, the inconvenience and time required to move the vehicle to enter the working position again for the local compaction work. In order to solve such a problem, in the present invention, as shown in FIGS. 3C and 3D, roller tilting actuators 371 for tilting the compaction roller 37 in the lateral direction are installed on both sides of the compaction roller 37 to provide a compaction roller ( Tilt 37 to either side of the moving body 10, the compaction roller 37 is provided with a roller horizontal angle sensor (not shown), the control unit is configured to adjust the tilting angle of the compaction roller 37 .

In addition, as shown in FIG. 2, a vibration pump 373 is provided at the lower end of the suspension arm 35 to transmit high-speed vibration to the compaction roller 37. The vibration formed is transmitted to the compaction roller 37, whereby the road surface is more firmly compacted. This is because the road surface becomes more firmly as the vibration type hits the road surface.

Ascon is pressed onto the surface of the compaction roller 37, so that a phenomenon that may hardly fall even after scraping with a tool may occur. In particular, when such a problem occurs during work, the road surface may not be evenly compacted.

In order to prevent such a phenomenon, in the present invention, as shown in FIG. 3B, a drop nozzle 72 receives water from the water tank 70 at a vertical upper portion of the compaction roller 37 and injects water onto the surface of the compaction roller 37. ) Is installed.

In this case, the drop nozzle 72 sprays a drop of water so that the amount of water drops at a constant speed. If the water supply is too fast and a lot of water is sprayed, the asphalt can be difficult to apply evenly to the damaged area.

And since the amount of water sprayed from the drop nozzle 72 is a small amount in the winter can be installed in the water tank 70 or the side to prevent the freezing heater (not shown) so that the water does not freeze.

On the other hand, the

front booms

216 and 217 are connected to the left and right transverse arms 211 by the hinge shaft 214 and are installed to be collapsible. At this time, it is the hinge actuator 215 shown in FIGS. 6A and 6B to unfold the

front booms

216 and 217 from the left and right cross arms 211. As such, the hinge actuator 215 unfolds or folds the front boom, thereby minimizing the space occupied by the entire front mechanism 12 in the traveling situation of the movable body 10.

As shown in FIG. 6A, the suction mechanism includes a fixing tube 231 fixedly installed on a side of the front boom in a direction parallel to the front boom, and an end connecting the one end of the fixing tube 231 to the side of the drum housing 229. A first bellows tube (not shown), and the second bellows tube 235 connecting the other end of the fixed tube 231 and the fixed frame.

Here, particularly preferably, the free rotation of the flange 238 and the second bellows tube 235 is allowed at the point where the other ends of the second bellows tube 235 and the fixed tube 231 are connected as shown in FIG. 6C. Link bearing 232 is installed, the rod-shaped rod stopper 233 in the radial direction is attached to the outer peripheral surface of the link bearing 232, the end of the rod stopper 233 is flange for fixing the flange 238 The other ends of the link bearing 232 and the second bellows tube 235 rotated together with the rod stopper 233 are stopped by being contacted with the plurality of bolt heads 234 penetratingly installed at the 238. The twist of the second bellows pipe 235 due to excessive rotation of the second bellows pipe 235 is prevented while allowing rotation within a predetermined range of the second bellows pipe 235.

That is, the second bellows tube 235 may be severely shaken due to the violent movement of the crushed mass during the suction of the crushed material. When the end of the second bellows tube 235 is completely fixed, the durability of the second bellows tube 235 itself may be reduced. And because there is a risk of breakage of the end connection portion constant rotational variation should be allowed, but if the rotational variation is allowed indefinitely the second bellows tube 235 itself can be twisted. At this time, it is the bar stopper 233 that suppresses the rotational variation of the second bellows tube 235 within a predetermined angle. In particular, the rod stopper 233 is installed at the same position as the bolt head 234 for fixing the flange 238 even without a separate device, so that the rod stopper 233 contacts the flange head 234 for fixing the flange 238 and thus the second Infinite rotation of the bellows tube 235 is suppressed.

In addition, since the suction mechanism has to be changed in length in the process of drawing out the second boom 217 constituting the front boom from the first boom 216, as shown in FIG. When the transfer pipe 239 is installed and the second boom 217 is withdrawn from the first boom 216, the internal transfer pipe 239 may be configured to be withdrawn from the fixed pipe 231. In this case, although not shown, the connection between the other end of the fixed tube 231 and the first bellows tube is made by connecting the end of the internal transfer tube 239 and the first bellows tube retractably inserted into the other end of the fixed tube 231.

Meanwhile, as shown in FIG. 6B, the lower part of the front mechanism part 12 has a footrest 243 connected to the bottom of the support 241 and the support 241, and a universal joint connecting the support 241 and the footrest 243. The support frame 24 which consists of 242 and the footrest 243 in which the universal joint 242 is centered is provided in several places.

Here, the support 241 is made of a support actuator (not shown) that is variable toward the vertical lower, the front mechanism portion 12 is provided with a horizontal meter (not shown), in a plurality of places in accordance with the measurement value of the horizontal meter (not shown) A control unit (not shown) is provided to control the installed actuator for maintaining the horizontality of the front mechanism part 12, so that even when the moving body 10 is to be positioned on an inclined surface, the moving body is provided by the supporting frame 24 installed in a plurality of places. Work can be done in a situation where level 10 is maintained.

On the other hand, the rear of the drum housing 229 is coupled to the lifting frame 222 provided with rails on both sides so that the drum housing 229 can be lowered or raised toward the asphalt floor, as shown in Figure 8a, the drum housing Coupling 229 and the inner boom end is achieved by coupling the inner boom end to the rear surface of the elevating frame 222.

The emulsifier tank 223 storing the ascon emulsifier for the ascon emulsifier is coupled to the upper portion of the drum housing 229 so that the drum housing 229 and the emulsifier tank 223 are lowered or raised along the lifting frame 222. At this time, the upper surface of the emulsifier tank 223 is provided with a cover frame 228 coupled integrally with the upper end of the lifting frame 222, the cover frame 228 penetrates the cover frame 228, the lower end of the emulsifier tank 223 Lifting actuator (2281) is fixed to the upper surface is installed, the emulsifier tank 223 and the drum housing (229) is raised or lowered together in accordance with the operation of the lifting actuator (2281).

An emulsifier is a substance that allows the ascon to remain dispersed without causing phase separation and must be added to the ascon when the ascon is applied. By the way, when the emulsifier is installed near the body 11 of the moving body 10, that is, the ascon hopper 41, the emulsifier supply pipe should be installed quite long. However, since the emulsifier is not a substance that is added to the ascon in large quantities, the emulsifier supply pipe must have a small diameter. There is no doubt that it will be difficult to clean.

Therefore, in the present invention, the emulsifier tank 223 is directly coupled to the vertical upper portion of the drum housing 229 so that the length of the emulsifier supply pipe (not shown) is minimized, and the diesel oil tank 224 in which the diesel oil for washing the emulsifier supply pipe is stored. Is arranged to be coupled to the back of the lifting frame 222 coupled to the back of the emulsifier supply pipe, the storage space and supply mechanism of the emulsifier and diesel oil necessary for the injection of ascone is disposed closest to the working position while minimizing the occupied space.

Meanwhile, as shown in FIG. 8C, the lower portion of the drum housing 229 has the same cross-sectional shape as the drum housing 229 and is made larger than the drum housing 229 to surround the outer surface of the drum housing 229, or the drum The same shape of the cross-section of the housing 229 and smaller than the drum housing 229 and the inner surface of the drum housing 229 can be inserted and withdrawn below the drum housing 229, and the lower cushion along the lower edge ( An airtight enclosure 226 to which the 227 is coupled may be installed.

The first bellows tube (not shown) described above connects the drum housing 229 with the end of the internal transfer tube 239. At this time, although not shown inside the drum housing 229, a blower (not shown) for floating the asphalt crushed material deposited on the bottom may be installed.

In this case, when the blower flows wind inside the drum housing 229 to float the crushed material, the inside of the space enclosed by the drum housing 229 and the floor is sealed as much as possible so that the crushed material can be smoothly sucked into the first bellows pipe (not shown). The first bellows tube (not shown) can suck the debris with maximum efficiency. However, the lower end of the drum housing 229 is not only a rigid member, but also to secure a space for the shredding drum 221 to perform the shredding operation, as shown in FIG. 8B, rather than the bottom of the shredding drum 221. Since it is slightly higher, the bottom of the drum housing 229 does not contact the asphalt bottom surface, so that the sealing cannot be made, so that the absorption efficiency of the crushed matter is remarkably low.

By the way, even if the cushion member is directly installed at the bottom of the drum housing 229, some degree of sealing can be achieved, but the distance between the bottom of the drum housing 229 and the bottom surface may vary with a constant width according to the shredding operation of the shredding drum 221. Therefore, even if the drum housing 229 is moved up and down within a certain range is necessary means for sealing.

Therefore, in the present invention, this problem is solved by installing the sealed enclosure 226 that is protruded and inserted from the lower end of the drum enclosure 229 in the drum enclosure 229.

The sealed enclosure 226 may be inserted into the drum enclosure 229 as shown in FIG. 8C or may be installed to enclose the lower portion of the drum enclosure 229 although not shown. In the embodiment of FIGS. 8C and 8D, the sealed enclosure 226 is installed to be inserted into or withdrawn from the bottom of the drum enclosure 229.

Since the sealed enclosure 226 needs to be in close contact with the ground even if there is a vertical movement of the drum enclosure 229, a mechanism is required to push the sealed enclosure 226 downward from the drum enclosure 229. It is the spring 2221 installed in FIG. 8D that does this.

The spring 2221 is embedded in the vertical cylinder 2264 installed on the outer wall of the drum housing 229 as shown in FIGS. 8C and 8D, and the piston arm 2226 subjected to the elastic force of the spring 2226 is sealed enclosure 226. The piston arm 2262 is installed to be fixedly connected to the outer wall, and the piston arm 2226 is installed through the vertical long hole 2263 formed in the drum housing 229, so that the sealed housing 226 even if the drum housing 229 is raised within a predetermined range. Since the force of close contact with the floor is applied, the sealing drum 221 maintains the sealing of the space in which the shredding operation is performed, so that the suction efficiency of the shredded material may be significantly increased.

At this time, the sealing cushion 227 is installed along the lower edge of the sealing enclosure 226, thereby increasing the sealing efficiency.

Meanwhile, as shown in FIGS. 6A and 6B, three protrusion shapes are provided so that the left and right cross arms 211 are not separated from the ends of the horizontal rails 212 when the left and right cross arms 211 move along the horizontal rails 212. Stopper 218 is installed.

The action of driving the horizontal movement of the left and right cross arms 211 may be made of a drive mechanism such as a motor pulley built in the drive box 213 installed on the rear side of the horizontal rail 212, as shown in FIG. 6D. The middle stopper 218 of the two stoppers 218 is configured as the limit switch 218-2 to cut off the driving power of the drive box 213 when it comes into contact with the left and right traverse arms 211 to the drive box 213. The durability of the motor (not shown) constituting the built-in drive mechanism can be further increased.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
