The foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of the embodiments with reference to the accompanying drawings, in which reference is made to the accompanying drawings.
Embodiment 1, this embodiment provides an asphalt pavement filling and sealing machine, as shown in fig. 1, which includes a cart 1, a storage tank 2 is mounted on the cart 1, a material injection port (not numbered) is disposed on a top wall of the storage pipe, and a pouring sealant (hot-melt pouring sealant) for repairing cracks on an asphalt pavement is injected into the storage tank 2 through the material injection port, and is characterized in that a heating device is disposed in the storage tank 2, the pouring sealant in the storage tank 2 is heated by the heating device to be in a hot-melt state (to meet a construction temperature requirement), and the pouring sealant in the hot-melt state is finally poured into the cracks, where it needs to be noted that the device is used in combination with a high-pressure blower, when repairing cracks, the cracks need to be widened and the size of the cuts can be adjusted in time according to the width types of the cracks, the high-pressure blower is used for cleaning dust, impurities and the like in the cracks with the grooves to meet design construction requirements, so that the pouring sealant can be well and tightly combined with the cracks when being poured into the cracks;
preferably, we are connected with force pump 3 (force pump 3 electric connection has external power supply) in storage tank 2 bottom, and provide a selection here, force pump 3 in this scheme can select the pitch pump for use) and outwards pump the casting glue that reaches heating temperature in storage tank 2 through force pump 3, certainly also can adopt the gravity flow as its ejection of compact mode, namely, the casting glue that is in hot melt state is independently outwards ejection of compact, select for use which kind of ejection of compact mode technical staff can carry out corresponding setting according to the actual demand when setting up, we install (mixing) shaft 22 and interval on (mixing) shaft 22 is provided with stirring fan blade 21 in storage tank 2 internal rotation, stirring shaft 22 is through the driving of agitator motor 62 who is fixed in 1 diapire of dolly (as shown in figure 8), when heating device heats the casting glue in storage tank 2, we drive (mixing) shaft 22 through stirring motor 62 and rotate and realize counterpointing in storage tank 2 through stirring fan blade 21 The pouring sealant in the material storage tank is stirred, so that the heat can be better transmitted (the heating is more uniform), and when the material needs to be discharged outwards, the pouring sealant can flow outwards out of the material storage tank 2 through the rotation of the stirring fan blades 21;
referring to the attached drawing 3, a bearing plate 4 is longitudinally and slidably mounted on one longitudinal side of a trolley 1, an L-shaped discharge pipe 5 is fixed on the bearing plate 4, referring to the attached drawing 13, the L-shaped discharge pipe 5 is in sliding fit connection with an outlet end of a pressure pump 3 (if the scheme is set, if the pressure pump 3 is not used, namely, a self-flow type is adopted as a discharge mode, the L-shaped discharge pipe 5 is directly in sliding fit connection with the bottom of a storage pipe), referring to the attached drawing 11, a middle rotary drum 6 is communicated with the bottom of the L-shaped discharge pipe 5, and valves 7 are respectively arranged at two ends of the middle rotary drum 6;
when the detection device is used specifically, firstly, the middle pipe 9 between the two spraying pipes 8 corresponds to the opened groove, that is, the middle pipe 9 is located at the middle position of the opened groove (when a constructor pushes the trolley 1 to move along the extending direction of the crack, the middle pipe 9 is located at the middle position of the crack as much as possible), then, the detection plate 10 vertically and slidably mounted on the middle rotary drum 6 is adjusted, so that the detection plate 10 descends to a proper position, that is, when the guide plate 11 (a plurality of guide wheels 12 are rotatably mounted on the guide plate 11, so that the guide plate 11 can walk along the side wall of the crack groove when being squeezed by the side wall of the crack groove) descends to be located in the opened groove, the downward movement of the detection plate 10 is stopped, and attention needs to be paid to the following steps: when the detection plate 10 is moved downwards, the two matched guide plates 11 are respectively positioned at two ends of the detection plate 10 under the action of the corresponding extension springs 13, at the moment, the distance between the two guide plates 11 is the largest, if the crack width of the initial position of the device for crack repair is wider (namely, the crack width is larger than the distance between the two guide plates 11), the two guide plates 11 can be directly moved downwards to the initial groove by moving the detection plate 10 downwards, if the crack of the initial position of the device for crack repair is narrower (the crack width is smaller than the distance between the two guide plates 11), in order to enable the two guide plates 11 to smoothly enter the opened groove when the detection plate 10 is moved downwards, when the guide plates 11 are about to enter the opened groove, the two guide plates 11 are manually pressed towards the direction of approaching each other, further shortening the distance between the two guide plates 11, so that the two guide plates 11 enter the opened groove, and when entering the groove, the two guide plates 11 respectively abut against two side walls of the groove under the action of the telescopic spring 13;
then, a pressure pump 3 is started to enable the pouring sealant in the storage tank 2 to enter a transfer cylinder 6 through an L-shaped discharge pipe 5, the pouring sealant in a hot melting state enters the transfer cylinder 6 and is downwards poured into a groove formed through an intermediate pipe 9 connected with the transfer cylinder to fill a crack, valves 7 are respectively installed at two longitudinal ends of the transfer cylinder 6, the bottom of each valve 7 is connected with a spray pipe 8, when the width of the crack is larger than the distance between two guide plates 11 (at the moment, the two guide plates 11 are located at the farthest distance under the action of a telescopic spring 13), the guide plates 11 and a transmission device connected with the guide plates enable the corresponding valves 7 to be in a completely opened state (at the moment, the pouring sealant entering the transfer cylinder 6 through the L-shaped discharge pipe 5 is downwards poured into the groove formed through the intermediate pipe 9 and the spray pipes 8 located at two longitudinal sides), when the width of the crack gradually decreases along with the movement of the device along the extending direction of the crack, the two guide plates 11 are forced to move towards the direction of approaching each other synchronously under the extrusion of the two side walls of the crack (at this time, the guide plates 11 slide along the detection plate 10 and the expansion springs 13 are compressed), and the guide plates 11 drive the corresponding valves 7 to close slowly through the transmission device connected with the guide plates 11, and it is noted that: in the process of slowly closing the valve 7, the amount of the pouring sealant flowing through the valve 7 is synchronously reduced, so that the outward discharge amount of the pouring sealant through the spraying pipes 8 positioned at the two longitudinal sides is gradually reduced in coordination with the gradual reduction of the width of the crack (the required amount of the pouring sealant poured into the crack groove is also reduced), the discharge amount of the pouring sealant is correspondingly changed along with the change of the width of the crack groove, and the pouring sealant is convenient for constructors to better control;
if the width of the crack is continuously reduced, so that the two guide plates 11 are extruded by the two side walls of the crack groove and move oppositely to a certain distance (it is set that the two side walls of the crack groove correspond to the discharge holes of the spraying pipes positioned at the two longitudinal sides in the vertical direction, that is, if the spraying pipes 8 continuously discharge outwards, the pouring sealant flowing out from the discharge holes of the spraying pipes 8 is poured onto a perfect road surface beside the crack groove), at the moment, the guide plates 11 just drive the corresponding valves 7 to be completely closed through the transmission devices connected with the guide plates 11, the spraying pipes 8 connected with the valves 7 do not discharge outwards, the situation that the pouring sealant flowing out from the spraying pipes 8 is poured onto the perfect road surface is well avoided, and certainly, when a constructor pushes the trolley 1 to construct along the crack extending direction, the position relation between the trolley 1 and the crack should be adjusted in real time, and the intermediate pipe 9 is located at the intermediate position of the intermediate crack groove as far as possible (the intermediate pipe is avoided) 9 inclines towards one side wall of the crack slot, so that excessive pouring sealant poured into the crack slot is concentrated on one side of the crack slot, the later compaction operation is not facilitated, and if the middle pipe 9 inclines towards one side wall of the crack slot too much, the pouring sealant flowing out of the spray pipe 8 can be poured onto a road surface beside the crack slot);
similarly, when the constructor advances along the extending direction of the crack, when the width of the crack widens again, the two guide plates 11 move along the detection plate 10 in the direction away from each other under the action of the extension spring 13, at this time, the guide plates 11 drive the valve 7 to be slowly opened through the transmission device connected with the guide plates 11, and the spraying pipe 8 connected with the valve 7 starts to discharge outwards, that is, when the width of the crack increases, the corresponding valve 7 is automatically opened and the spraying pipe 8 connected with the corresponding valve discharges outwards, so that the discharge amount of the pouring sealant is correspondingly increased in cooperation with the increase of the width of the crack;
preferably, in order to avoid the situation that the middle pipe 9 cannot be positioned at the middle position of the crack groove in real time due to uncertainty of naked eye observation when the trolley 1 is manually pushed to advance along the crack extension direction, a deviation correcting device is arranged on the trolley 1, specifically, an arc-shaped rail 14 is fixed on the upper end face of the valve 7, an arc-shaped conductive block 15 is slidably arranged on the lower end face of the arc-shaped rail 14, as shown in fig. 12, an arc-shaped groove (not numbered) in the figure which is in sliding fit with the arc-shaped conductive block 15 is arranged in the arc-shaped rail 14, a resistor disc 16 (the resistor disc 16 is arranged in an arc shape) is fixedly arranged on one arc-shaped side wall of the arc-shaped groove, the arc-shaped conductive block 15 is slidably arranged in the arc-shaped groove and is in sliding fit contact with the resistor disc 16, and the arc-shaped conductive block 15 and the resistor disc 16 are connected in series in the same voltage stabilizing loop when the arrangement is performed, when the two valves 7 are in a fully opened state, the arc-shaped conductive block 15 is positioned at one end of the resistance chip 16, the resistance value of the resistance chip 16 connected into the voltage stabilizing loop is the maximum (the current in the voltage stabilizing loop is the minimum at this time), when the guide plate 11 moves along the detection plate 10 under the extrusion of the side wall of the crack slot, the arc-shaped conductive block 15 is driven by the transmission device to move along the arc-shaped track 14 (along with the movement of the arc-shaped conductive block 15, the resistance value of the resistance chip 16 connected into the voltage stabilizing loop is reduced, and the current in the voltage stabilizing loop is slowly increased), if a constructor pushes the trolley 1 to move along the crack slot, the middle position of the crack slot cannot be located in real time due to uncertainty of naked eye observation, the extrusion degree of the crack slot of the two guide plates 11 is different at this time, and the moving distances of the two guide plates 11 along the detection plate 10 are also different, when the two guide plates 11 move along different distances along the detection plate 10, the transmission device connected with the two guide plates drives the corresponding arc-shaped conductive blocks 15 to move along the arc-shaped tracks 14 at different distances, so that the currents in the two voltage stabilizing loops are different, the two voltage stabilizing loops are respectively and electrically connected with the deviation correcting device, so that when the current in one voltage stabilizing loop is small (if the current in the voltage stabilizing loop is smaller than the current in the other voltage stabilizing loop, the moving distance of the arc-shaped conductive block 15 connected in series in the voltage stabilizing loop along the arc-shaped track 14 is small, and the degree of extrusion of the guide plate 11 corresponding to the other voltage stabilizing loop by the side wall of the crack groove is large, namely, the distance between the middle pipe 9 and the guide plate 11 is larger than the distance between the other guide plate 11), at the moment, the deviation correcting device controls the bearing plate 4 to move towards the direction close to the guide plate 11, the degree of the other guide plate 11 extruded by the side wall of the crack groove is reduced, so that the middle pipe 9 moves towards the direction close to the middle position of the crack groove, the extruding degrees of the two expansion springs 13 are the same (at the moment, the currents in the two pressure stabilizing loops are the same), the deviation correcting device controls the bearing plate 4 to stop moving, and at the moment, the middle pipe 9 is located at the middle position of the crack groove;
when the current in one of the voltage stabilizing loops is larger, namely, the current in the voltage stabilizing loop is larger than the current in the other voltage stabilizing loop, it means that the arc-shaped conductive block 15 connected in series in the voltage stabilization loop moves a larger distance along the arc-shaped rail 14, and the guide plate 11 corresponding to the other stabilizing circuit is extruded by the side wall of the crack groove to a smaller extent, i.e. the intermediate tube 9 is inclined more towards the orientation of the guide plate 11, the deviation-correcting device controls the carrier plate 4 to move towards the orientation away from the guide plate 11, and thus the extent to which the guide plate 11 is pressed against the side walls of the slot is reduced, so that the intermediate tube 9 is moved towards a position close to the middle of the slot, so that the two extension springs 13 are extruded to the same degree (at the moment, the currents of the two voltage stabilizing loops are the same), the deviation correcting device controls the bearing plate 4 to stop moving, and the middle pipe 9 is positioned in the middle of the crack groove;
in this scheme, adjust the position that middle pipe 9 was located in the crack groove in real time through deviation correcting device, make middle pipe 9 be in crack groove intermediate position department all the time, avoided leading to the deviation because of artifical visual observation, make middle pipe 9 more and then make the emergence of pouring into the too much concentrated certain side position condition in the crack groove of pouring into to the crack groove of pouring sealant to certain side slope of crack groove (if the deviation slope is too much, still can lead to toppling over to the other road surface of crack groove from the material that sprays pipe 8 and flow), namely, through setting up the position of middle pipe 9 of deviation correcting device and artifical through the initiative adjustment of naked eye, make the device when carrying out crack repair, the reliability is higher.
Embodiment 2, on the basis of embodiment 1, referring to fig. 11, we rotatably install a control ball 17 in a valve 7 and directly above a spray pipe 8, and the outer diameter of the control ball 17 is the same as the inner diameter of a transfer cylinder 6, we have channels 23 in the control ball 17, which are communicated and vertically arranged, wherein one channel 23 is coaxially arranged with the transfer cylinder 6, and the other channel 23 is coaxially arranged with the spray pipe 8, when the control ball 17 is at the position shown in fig. 11, the control ball is at the maximum open state, enters the pouring sealant in the transfer cylinder 6 in a hot-melt state, enters the channel 23 in the vertical direction through the horizontally arranged channel 23, and is discharged outwards through the spray pipe 8;
a rotating rod 18 is integrally and coaxially fixed at the upper end of a control ball 17, the control ball 17 is rotatably installed on the top wall of a valve 7 through the rotating rod 18, the rotating rod 18 extends upwards out of the valve 7 and one end of the rotating rod 18 extends out of the valve 7 to be fixedly provided with a rotating handle 19, an outer gear ring 20 coaxially arranged with the rotating rod 18 is rotatably installed on the upper end face of the valve 7, one end, far away from the rotating rod 18, of the rotating handle 19 is rotatably installed with the outer gear ring 20, when a guide plate 11 is extruded by the side wall of a crack groove to move along a detection plate 10, the outer gear ring 20 is synchronously driven to rotate through a transmission device, the control ball 17 is synchronously driven to rotate in the valve 7 through the rotating handle 19 along with the rotation of the outer gear ring 20, a channel 23 coaxially arranged with a transfer cylinder 6 is slowly deviated in the rotating process of the control ball 17 (along with the rotation of the control ball 17, the position, where the horizontally arranged channel 23 is communicated with the transfer cylinder 6, is slowly shielded by the inner wall of the transfer cylinder 6), further, the amount of the potting adhesive entering the channel 23 from the interior of the middle rotary drum 6 is slowly reduced, so that when the guide plate 11 moves a certain distance along the detection plate 10 under the extrusion of the side wall of the crack groove, that is, when the guide plate 11 and the side wall of the crack groove are at corresponding positions in the vertical direction (at this time, if the guide plate 11 continues to move along the detection plate 10, the potting adhesive is directly poured on the road surface beside the crack groove), at this time, the transmission device drives the rotary handle 19 to rotate for 90 degrees through the outer gear ring 20, and then the valve 7 is completely closed, that is, at this time, the opening end of the channel 23 coaxially arranged with the middle rotary drum 6 is completely shielded by the inner wall of the middle rotary drum 6, and at this time, the potting adhesive in the middle rotary drum 6 cannot enter the corresponding spray pipe 8 through the channel 23 (the valve 7 is in a closed state);
it should be noted that the rotation angle of the control ball 17 depends on the extrusion degree of the guide plate 11 by the side wall of the crack slot (i.e. the distance of the guide plate 11 moving along the detection board 10), and when the outer ring gear 20 rotates, it will synchronously drive the corresponding arc conductive block 15 to move in the arc guide rail, so as to change the resistance value of the resistance sheet 16 connected to the arc conductive block 15 into the voltage stabilizing loop, and when the current in the two voltage stabilizing loops is different (representing that the two guide plates 11 receive the extrusion degree of the side wall of the crack slot, at which time the middle tube 9 is no longer in the middle of the crack slot and has been shifted), then the deviation rectifying device electrically connected to the voltage stabilizing loop controls the movement of the bearing plate 4 towards the corresponding direction, so as to control the movement of the bearing plate 4 and make the middle tube 9 towards the middle of the crack slot according to the extrusion condition (the distance of the two guide plates 11 moving along the detection board 10) of the bearing plate 11 The position is shifted in the direction that eventually causes the two guide plates 11 to move the same distance along the detection plate 10 and the current in the two voltage stabilizing circuits is the same (the middle tube 9 is in the middle of the crack groove).
Embodiment 3, on the basis of embodiment 2, referring to fig. 2, an L-shaped slideway 24 is fixed on one lateral side of two valves 7, a detection plate 10 is vertically and slidably mounted on the two L-shaped slideways 24, a screw 25 rotatably mounted between the two L-shaped slideways 24 is screwed to adjust the vertical position of the detection plate 10, when the device is not in a working state, the detection plate 10 is at a higher position by screwing the screw 25 initially, that is, when the device is not in use, a guide plate 11 slidably mounted on the lower end surface of the detection plate 10 is arranged at a certain distance from the ground, so that the transfer and transportation of the device are not hindered, and when the device needs to work, the detection plate 10 is driven to move downwards by screwing the screw 25, and the two guide plates 11 move downwards to a formed crack groove;
when the guide plate 11 is squeezed by the side wall of the slot, the guide plate moves along the detection plate 10 to synchronously drive the transmission rack 26 connected with the detection plate, the transmission rack 26 moves to drive the meshing gear 27 which is rotatably installed on the detection plate 10 and is meshed with the detection plate to rotate, as shown in fig. 16, a transmission shaft 28 which is axially and slidably matched with the meshing gear 27 is rotatably installed on the L-shaped slide way 24, the transmission shaft is axially and slidably matched, in order to match that when the detection plate 10 is changed in the vertical position, the meshing gear 27 can transmit power to the transmission shaft 28 when being driven by the transmission rack 26 to rotate, the upper end of the transmission shaft 28 is connected with a transmission gear 30 which is rotatably installed on the upper end surface of the valve 7 and is meshed with the outer gear ring 20 through a transmission pulley set 29, when the transmission shaft 28 is driven by the meshing gear 27 to rotate, the outer gear ring 20 is synchronously driven to rotate by the transmission gear 30, the external gear ring 20 rotates to drive the control ball 17 rotatably arranged in the valve 7 to rotate through the rotating handle 19, so that the effect of changing the opening degree of the valve 7 is realized;
we set the two valves 7 to be in a fully open state when the two guide plates 11 are not in contact with the side walls of the slit groove (when the two guide plates 11 are in the furthest position under the action of the extension springs 13), i.e. the control ball 17 rotatably mounted in the valve 7 is in the position as shown in figure 11,
embodiment 4, on the basis of embodiment 3, referring to fig. 6, the bearing plate 4 is screwed to rotate a deviation-correcting lead screw 31 installed on the trolley 1, and the deviation-correcting lead screw 31 is connected with a deviation-correcting motor 32, when we set up, the electromagnets 37 located at both sides of the moving plate 33 are respectively connected in series with the corresponding arc-shaped conductive blocks 15 and the corresponding resistive sheets 16 in the same voltage-stabilizing circuit, that is, in this scheme, there are two sets of arc-shaped conductive blocks 15 and resistive sheets 16 which are matched, so we also set up two electromagnets 37 matched with the two sets of arc-shaped conductive blocks 15 and resistive sheets 16 (the arc-shaped conductive blocks 15 and the resistive sheets 16 far from the trolley 1 are matched in series with the electromagnets 37 far from the trolley 1, the arc-shaped conductive blocks 15 and the resistive sheets 16 close to the trolley 1 are matched in series with the electromagnets 37 also close to the trolley 1), when initially the two guide plates 11 are not in contact with the side walls of the crack groove, at this time, the arc-shaped conductive blocks 15 slidably mounted in the arc-shaped guide rails are both located at one end of the arc-shaped guide rails, and the resistance values of the two resistance cards 16 connected into the voltage stabilizing circuits corresponding to the two resistance cards are the same, so that the currents flowing through the two electromagnets 37 are also the same, and the electromagnetic forces generated by the two electromagnets 37 are also the same, so that the moving plate 33 is in a stable state under the actions of the electromagnets 37 located at the two sides of the moving plate and the deviation-correcting springs 34 (the distance between the moving plate 33 and the two electromagnets 37 is the same, and when the moving plate 33 is arranged, the moving plate 33 is located at the middle position of the two electromagnets 37, and the extension degrees of the two deviation-correcting springs 34 are kept the same);
we respectively fix plugs 35 on both sides of the moving plate 33 and fix sockets 36 matched with the plugs 35 at positions located on both lateral sides of the moving plate 33 (two electromagnets 37 are respectively and fixedly installed on the upper end faces of the sockets 36 corresponding to the electromagnets), and we all adopt the plugs 35 and the sockets 36 in the prior art (when we set the plugs 35 and the sockets 36 matched with each other, the distance between the plugs 35 and the sockets 36 is slightly shorter), so that the circuit can be switched on when the plugs 35 and the sockets 36 are matched together, and for the prior art, a person skilled in the art can make an improvement suitable for the scheme on the basis of the prior art when setting, and because the improvement is not the improvement point of the scheme, the description is not too much again;
when the middle tube 9 deviates from the middle position of the slot, that is, the middle tube 9 inclines towards a certain sidewall of the slot (we set the middle tube 9 to incline towards the direction close to the trolley 1), so that the degree of extrusion of the sidewall of the slot on the guide plate 11 close to the trolley 1 is greater (the degree of extrusion of the sidewall of the slot on the other guide plate 11 is smaller), and therefore, the greater the distance that the arc-shaped conductive block 15 corresponding to the guide plate 11 moves along the arc-shaped guide rail corresponding to the guide plate 11 is, the greater the current in the voltage stabilizing loop in which the arc-shaped conductive block 15 is located is increased (the resistance value of the resistor 16 connected in series with the arc-shaped conductive block 15 in the voltage stabilizing loop is decreased), and the greater the electromagnetic force generated by the electromagnet 37 connected in series in the voltage stabilizing loop is increased (the electromagnetic force generated by the electromagnet 37 corresponding to the other guide plate 11 is smaller), so that the electromagnetic forces generated by the two electromagnets 37 are different, at this time, the moving plate 33 is attracted by electromagnetic forces with different magnitudes on the two lateral sides (we fix iron sheets corresponding to the electromagnets 37 on the two lateral sides of the upper end of the moving plate 33 respectively), so the moving plate 33 moves towards the electromagnets 37 with larger electromagnetic force (i.e. synchronously drive the plug 35 to move towards the socket 36 close to the trolley 1), at this time, the plug 35 fixedly installed on the moving plate 33 is inserted into the socket 36 corresponding to the plug 35, we set the socket 36 and the plug 35 which are matched with each other to be connected in series in the forward rotation loop of the deviation-correcting motor 32, when the plug 35 is inserted into the socket 36, the forward rotation loop of the deviation-correcting motor 32 is switched on, and the deviation-correcting screw 31 is driven by the deviation-correcting motor 32 to drive the bearing plate 4 to move towards the direction far away from the trolley 1 until the middle pipe 9 is located at the middle position of the crack groove again, at this time, the extent of squeezing of the two guide plates 11 by the side walls of the crack groove is the same, and the currents in the two voltage stabilizing loops are the same (the two electromagnets 37) The magnetic force is the same), so that the moving plate 33 moves away from the trolley 1 under the action of the deviation rectifying spring 34 at the moment until the moving plate moves to the middle position of the two electromagnets 37, stops moving and returns to the initial position;
similarly, when the middle tube 9 inclines towards the direction far away from the trolley 1, the electromagnetic force generated by the electromagnet 37 far away from the trolley 1 is larger, and then the moving plate 33 is driven by the electromagnetic force to move towards the direction far away from the trolley 1, the plug 35 is driven to move towards the corresponding socket 36 synchronously, so that the plug 35 is inserted into the socket 36, the plug 35, the socket 36 and the reverse loop of the deviation-correcting motor 32 which are far away from the trolley 1 and matched are mutually connected in series, therefore, the reverse loop of the deviation-correcting motor 32 is switched on, the deviation-correcting motor 32 drives the deviation-correcting lead screw 31 to rotate and drives the bearing plate 4 to move towards the direction close to the trolley 1, so that the middle tube 9 moves to the middle position of the crack groove again, and when the middle tube 9 moves to the middle position of the crack groove, the currents in the two voltage-stabilizing loops are the same again, so that the moving plate 33 is subjected to the adsorption acting forces of the electromagnetic forces of the electromagnets 37 at the two sides thereof, at this time, the moving plate 33 is synchronously moved to the middle position of the two electromagnets 37 under the action of the deviation rectifying spring 34.
Example 5, on the basis of example 4, referring to fig. 14, we have L-shaped frames 39 longitudinally installed on the detection plate 10 at intervals in a sliding manner, and the upper ends of the L-shaped frames 39 are connected with the transmission rack 26, we have the upper ends of the guide plates 11 integrally connected with the connecting rods 40 and slidably installed at the horizontal positions of the L-shaped frames 39 through the connecting rods 40 when setting up the guide plates 11, referring to fig. 15, we have locating means for locating the connecting rods 40 on the L-shaped frames 39, when the two L-shaped frames 39 do not touch the unlocking means arranged at the lower end of the detection plate 10 (we set up that when the L-shaped frames 39 touch the unlocking means, the guide plates 11 just move along the detection plate 10 under the extrusion of the side walls of the crack slot to make the discharge port at the lower end of the spray pipe 8 and the side walls of the crack slot at the corresponding position in the vertical direction, and if the guide plates 11 continue to move, the pouring sealant flowing out from the spray pipe 8 is poured onto the road surface beside the crack slot), the connecting rod 40 is positioned by the positioning device, namely, the guide plate 11, the connecting rod 40 and the L-shaped frame 39 keep moving synchronously, and therefore when the L-shaped frame 39 does not touch the unlocking device, the guide plate 11 is extruded by the side wall of the crack groove to synchronously drive the L-shaped frame 39 to move along the detection plate 10 and compress the expansion spring 13, and the L-shaped frame 39 moves to further move through the transmission rack 26 connected with the L-shaped frame 39, so that the effect of driving the meshing gear 27 to rotate is achieved;
along with the continuous reduction of the width of the crack groove, when the two guide plates 11 drive the L-shaped frames 39 to move to corresponding positions along the detection plate 10 under the extrusion of the side walls of the crack groove (namely, when the opposite ends of the two L-shaped frames 39 are respectively released from the unlocking device arranged at the bottom of the detection plate 10), at the moment, the L-shaped frames 39 cannot move continuously along the detection plate 10, a sliding cavity (not numbered in the figure) which is arranged on the detection plate 10 and is in sliding fit connection with the vertical parts of the L-shaped frames 39 only can allow the L-shaped frames 39 to move to the positions along the detection plate 10 (under the action of the deviation correcting device, the two L-shaped frames 39 move to the positions simultaneously and the driving racks 42 fixedly arranged on the two connecting rods 40 just start to be meshed with the driving gears 43 at the same time), at the moment, the unlocking device realizes the unlocking of the positioning device, along with the continuous reduction of the width of the crack groove, the two guide plates 11 are pressed by the side walls of the slot to move in the direction of approaching each other, that is, the link 40 slidably mounted on the horizontal portion of the L-shaped frame 39 is moved along the L-shaped frame 39 and the control spring 41 connected between the link 40 and the L-shaped frame 39 is compressed;
when the unlocking device releases the positioning of the positioning device, the two driving racks 42 are just about to start to be meshed with the driving gear 43, if the width of the crack groove is continuously reduced, the two guide plates 11 are further forced to move towards the direction of approaching each other, the driving gear 43 is driven to rotate by the two driving racks 42 (when the unlocking device is arranged, the two driving racks 42 are vertically arranged at intervals and are respectively meshed with the gear systems of the driving gear 43 at the upper end and the lower end), the driving gear 43 rotates and drives the driving device which is rotatably installed on the detection plate 10 through the driving pulley set 44, the telescopic pipe 45 is vertically and slidably installed at the bottom of the middle pipe 9, as shown in figure 11, and the telescopic pipe 45 can realize the position adjustment relative to the middle pipe 9 in the vertical direction through the driving of the driving device (the driving device comprises a driving pulley set 44 connected with a first worm 46 which is rotatably installed on the detection plate 10, the first worm 46 is matched with a first worm wheel 47 which is rotatably arranged on the detection plate 10, a driving shaft 48 which is axially and slidably matched with the first worm wheel 47 is rotatably arranged between the two L-shaped slide ways 24, the driving shaft 48 is driven by a lifting belt wheel set 49 connected with the driving shaft 48 to be provided with a limiting rod 50 which is rotatably arranged on the middle pipe 9, two limiting rods 50 are rotatably arranged at two axial sides of the middle pipe 9, the telescopic pipe 45 is vertically and slidably matched with the two limiting rods 50, and one limiting rod 50 is in threaded fit with the telescopic pipe 45, so that when the width of a crack groove is narrower and narrower, the driving device is driven by the driving gear 43 to finally drive the telescopic pipe 45 to move downwards, the distance between a discharge port of the middle pipe 9 and the crack groove is reduced by moving the telescopic pipe 45 up and down, and the telescopic pipe 45 is conveniently aligned with the crack groove by naked eyes of a constructor, the narrower the width of the crack groove is, the more difficult it is for the constructor to control the corresponding relationship between the middle pipe 9 and the crack groove, and the distance between the discharge port of the middle pipe 9 and the crack groove is reduced by moving the extension pipe 45 downwards, so that the constructor can better pour the pouring sealant into the crack groove with the narrower width;
similarly, when the width of the crack slot is widened from narrow to wide, the two guide plates 11 are moved away from each other by the control spring 41 and the telescopic tube 45 is driven by the driving gear 43 and the driving device to move upwards (because the distance between the discharge port of the middle tube 9 and the crack slot is reduced, the bottom of the telescopic tube 45 touches the road surface or the side wall of the crack slot causes damage to the discharge port, so when the width of the crack slot is widened, the telescopic tube 45 needs to be moved upwards in time to avoid the damage).
Embodiment 6, on the basis of embodiment 5, referring to fig. 16, the positioning device includes a U-shaped rod 51 installed in a horizontal position of the L-shaped frame 39 in a sliding manner, and a positioning spring 52 is connected between two engaged U-shaped rods 51, a positioning hole 53 is provided at the top of the link 40 to engage with one of the arms of the U-shaped rod 51, when the link 40 is in a positioned state, one of the arms of the two engaged U-shaped rods 51 is inserted into the positioning hole 53 provided at the top of the link 40, thereby positioning the link 40, and at this time, the positioning spring 52 connected between the two U-shaped rods 51 is in a stretched state, the other arm of the two U-shaped rods 51 is chamfered (as shown in fig. 16), referring to fig. 17, the unlocking device is a boss 54 fixedly installed on the lower end face of the detection plate 10, and both longitudinal sides of the boss 54 are chamfered (when we set initially, the boss 54 is spaced apart from the two L-shaped brackets 39 at both longitudinal ends thereof), when the L-shaped brackets 39 are moved along the detection plate 10 and moved to be unable to move further, the arms of the two co-operating U-shaped bars 51 now rounded just touch the boss 54 at the rounded corner to force the two U-shaped bars 51 to move away from each other, so that the portions of the two U-shaped bars 51 inserted into the positioning holes 53 are withdrawn outward (at this time the links 40 are released from the positioning), under the action of the boss 54, the two U-shaped rods 51 can only be inserted into the middle of the positioning hole 53 and withdrawn outwards from the positioning hole 53, but can not be withdrawn from the horizontal part of the L-shaped frame 39, and along with the continuous reduction of the width of the crack groove, so that the connecting rods 40 connected to the guide plate 11 continue to move towards each other along the L-shaped brackets 39 (at which time one of the cantilevered rounded corners of the U-shaped bars 51 abuts against the lateral side wall of the boss 54 and no longer moves with the L-shaped brackets 39 in the current position);
it is to be noted here that: when the two L-shaped frames 39 move to a position where they cannot move further along the detecting plate 10, the unlocking device releases the positioning of the link 40 and the link 40 starts to move along the horizontal position of the L-shaped frame 39, and at this time, it is necessary to provide locking devices for locking the L-shaped frames 39 on the left and right sides of the detecting plate 10, that is, when the unlocking device releases the positioning of the link 40, the locking devices provided on the detecting plate 10 synchronously lock the L-shaped frames 39 (to avoid that when the link 40 and the L-shaped frame 39 are not kept as a whole, the two L-shaped frames 39 move away from each other due to the elastic force of the extension spring 13), and as will be described in detail below, with respect to the arrangement of the locking devices, we can install energizing magnets 37 on both sides of the boss 54 in the longitudinal direction (the energizing magnets 37 are connected in series in an electrical circuit and when the electrical circuit is energized, the energized magnet 37 generates electromagnetic force) and a metal sheet which is easy to be attracted by the magnet is installed at the connecting position of the vertical part and the horizontal part of the L-shaped frame 39, a pressure sensor is installed on the bottom wall of the positioning hole 53 in a sliding way (a spring is connected between the pressure sensor and the bottom wall of the positioning hole 53, when the connecting rod 40 is positioned, a cantilever inserted into the positioning hole 53 of the U-shaped rod 51 is abutted against the pressure sensor and the spring is compressed), and the pressure sensor is electrically connected with a microcontroller (the pressure sensor and the microcontroller are matched and only responsible for the connection of an electrical circuit), when one cantilever of the two U-shaped rods 51 is slowly withdrawn from the positioning hole 53, the pressure sensor detects the change of a pressure signal (the received pressure is slowly reduced), when the pressure is reduced to a certain value (at the moment, one cantilever of the U-shaped rod 51 is just completely withdrawn from the positioning hole 53), the pressure sensor sends a signal to the microcontroller and controls the electrical loop to be connected through the microcontroller, so that the electrified magnet 37 is electrified to generate electromagnetic force and the L-shaped frame 39 is stably kept at the current position through adsorbing the metal sheet arranged at the connecting position of the vertical part and the horizontal part of the L-shaped frame 39, namely, when the connecting rod 40 and the L-shaped frame 39 are not kept as a whole and move relatively, the electromagnetic force generated by the electrified magnet 37 attracts the metal sheet to be balanced with the elastic force of the extension spring 13;
when the width of the crack groove is widened, the two connecting rods 40 move along the L-shaped frame 39 towards the direction away from each other under the action of the control spring 41, so that the positioning hole 53 arranged at the upper end of the connecting rod 40 moves to the position corresponding to one cantilever of the two U-shaped rods 51, one side of the connecting rod 40 facing the limit switch is abutted against the limit switch and the limit switch is triggered, the limit switch sends a signal to the microcontroller and controls the electric circuit to be disconnected through the microcontroller, so that the magnetic force of the energized magnet 37 disappears, and the L-shaped frame 39 moves towards the initial position under the action of the extension spring 13 along with the continuous increase of the width of the crack groove, and then the U-shaped rods 51 are driven to move synchronously, so that a cantilever of the U-shaped rods 51 with a rounded corner is slowly separated from one longitudinal end of the boss 54, and the other cantilever of the two U-shaped rods 51 is slowly inserted into the positioning hole 53 under the action of the positioning spring 52, thereby realizing the effect of reconnecting the connecting rod 40 and the L-shaped frame 39 together.
Embodiment 7, on the basis of embodiment 5, referring to fig. 3, the tank wall of the storage tank 2 is hollow, the heating device includes a spiral heating pipe 55 disposed in the tank wall of the storage tank 2, the bottom of the spiral heating pipe 55 is communicated with a heating box 71 (as shown in fig. 3) fixed on the trolley 1, referring to fig. 8, the spiral heating pipe 55 is vertically communicated with a plurality of input pipes 56 extending outward from the storage tank 2 at intervals, the plurality of input pipes 56 are communicated with a transfer chamber 57 fixed on the trolley 1, and the top of the transfer chamber 57 is communicated with the heating box 71;
we select heat conduction oil to heat the potting adhesive in the storage tank 2, we set a heating furnace for heating the heat conduction oil in the heating box 71 and a pressure pump at the outlet of the heating furnace to achieve the effect of pumping the heat conduction oil in the heating furnace outwards and entering the transfer cavity 57 (regarding the heating mode of the heating furnace, when the setting is performed by a person skilled in the art, improvement can be made according to the prior art by combining with the scheme, and not much description is made again), the heat conduction oil entering the spiral heating pipe 55 finally flows back to the heating furnace in the heating box 71 through the bottom of the spiral heating pipe 55, initially, we add the potting adhesive in a liquid state into the storage tank 2 and make the floating ball 58 vertically and slidably installed in the storage tank 2 in a floating state under the buoyancy of the liquid potting adhesive, and when the storage tank 2 is in a full state, the input pipe 56 positioned at the uppermost part is set to be communicated with the transfer cavity 57 (the connecting valve corresponding to the input pipe 56 positioned at the uppermost part is in an open state), heat conduction oil enters the spiral heating pipe 55 from the transfer cavity 57 through the input pipe 56 positioned at the uppermost part and flows through the material storage tank 2 from top to bottom, the heating (heat preservation) effect of pouring sealant is realized, and finally the pouring sealant flows back to the heating furnace from the bottom of the spiral heating pipe 55, along with the consumption of materials, the liquid level of the pouring sealant in the material storage tank 2 is gradually reduced, so the floating ball 58 also moves downwards slowly under the action of the self gravity, the floating ball 58 drives the wire wheel 60 to rotate through the wire rope 59 connected with the floating ball 58 (the floating ball 58 moves downwards under the action of the self gravity to drive the wire wheel 60 to rotate so as to overcome the acting force of the torsion spring 61 on the wire wheel 60, and because the buoyancy of the pouring sealant liquid is larger, when the floating ball 58 is arranged, also make it have certain weight), we have the second worm 69 that rotates with the coaxial line wheel 60 in the storage tank 2 roof and the second worm 69 cooperates with the second worm wheel 70 that installs in the storage tank 2 roof of rotation, the second worm wheel 70 drives the connection valve controlling means through the control pulley group 68, finally realize, when the liquid level in the storage tank 2 drops to a certain height position, make the connection valve close to this height position open under the effect of the connection valve controlling means (meanwhile the connection valve located at the upper end of this connection valve is closed by the connection valve controlling means), thus make the conduction oil located in the transfer chamber 57 flow into the spiral heating pipe 55 through the input pipe 56 corresponding to this connection valve (at this moment the conduction oil no longer flows through the spiral heating pipe 55 located above this input pipe 56), because there is no pouring sealant in the storage tank 2 located at this connection valve upper end at this moment, therefore, the space of the storage tank 2 above the connecting valve does not need to be heated, and the dissipation of heat energy is reduced;
one-way valves are arranged at the communication parts of the plurality of input pipes 56 and the spiral heating pipes 55, so that under the action of the one-way valves, heat conduction oil can only flow downwards from the upper ends of the spiral heating pipes 55 but cannot flow upwards in the spiral heating pipes 55 (when the one-way valves are arranged, the one-way valves are arranged at the upper rotary pipeline parts of the communication parts of the input pipes 56 and the spiral heating pipes 55), namely, when the heat conduction oil enters the spiral heating pipes 55 from one input pipe 56 positioned below, the heat conduction oil only flows downwards along the spiral heating pipes 55 and flows back to the heating furnace in the heating box 71, and cannot flow upwards along the spiral heating pipes 55;
the torsion spring 61 is connected with the reel 60, so that: when no material is initially in the storage tank 2, the floating ball 58 is at the bottommost portion of the storage tank 2 and the string 59 wound on the reel 60 is in a release state (we set that the torsion spring 61 generates a certain torsion force at this time, but the torsion force is not enough to pull the floating ball 58 upwards through the reel 60), when we add the pouring sealant in liquid into the storage tank 2, the floating ball 58 at the bottom portion moves upwards along the inner wall of the storage tank 2 under the buoyancy action of the pouring sealant liquid, and the string 59 loosens along with the upwards movement of the floating ball 58, so we solve the problem through the torsion spring 61, that is, when the floating ball 58 moves upwards under the buoyancy action, the torsion spring 61 rotates the reel 60 to wind the loosened string 59 on the reel 60, so as to achieve the tightening effect of the string 59, and along with the continuous adding of the amount of the pouring sealant, the position of the floating ball 58 in the storage tank 2 rises synchronously and the string 59 is wound synchronously under the action of the torsion spring 61 Tight (wound on reel 60).
Example 8 in example 7, referring to fig. 5, the connection valve includes a stepped circular truncated cone 63 axially slidably mounted on one end of the input pipe 56 close to the transfer chamber 57 and a return spring 64 is connected between the stepped circular truncated cone 63 and the input pipe 56, when the storage tank 2 is filled with the material, the connection valve control means presses the contact plate 65 positioned at the uppermost end and forces the larger diameter end of the stepped circular truncated cone 63 connected to the contact plate 65 closer to the storage tank 2 than the stepped circular truncated cone 63 positioned therebelow, that is, the return spring 64 connected between the stepped circular truncated cone 63 and the input pipe 56 is in a stretched state, at which the uppermost input pipe 56 and the transfer chamber 57 are in a communicated state and the heat transfer oil is introduced into the spiral heating pipe 55 through the input pipe 56, and the float 58 moves downward by its own weight and pulls the wire reel 60 to rotate through the wire 59 as the material level in the storage tank 2 drops (in this process, the torsion spring 61 is the torsion spring 61 and the return spring 64 is rotated When the liquid level in the storage tank 2 drops to a position close to the next input pipe 56, the wire wheel 60 drives the connection valve control device and presses the contact plate 65 corresponding to the input pipe 56, so that the stepped round table 63 corresponding to the input pipe 56 moves towards the direction close to the storage tank 2 (meanwhile, the stepped round table 63 located above does not move towards the direction away from the storage tank 2 under the action of the return spring 64 under the action of the connection valve control device any more, and the partition between the input pipe 56 and the transfer chamber 57 corresponding to the stepped round table 63 is realized), at this time, the heat conduction oil in the transfer chamber 57 starts to enter the spiral heating pipe 55 through the input pipe 56, and the residual material in the storage tank is heated and insulated, and the following processes are the same as above and are not described more.
Example 9, on the basis of example 8 and with reference to fig. 4, the connection valve control device includes an abutting rod 66 vertically slidably mounted in the transfer chamber 57 and making the abutting rod 66 coincide with the arc-shaped surface portion of the abutting plate 65 in vertical projection, and initially, when the material storage tank 2 is filled with the material, the abutting rod 66 and the abutting plate 65 positioned at the uppermost end abut against each other and make the distance between the abutting plate 65 and the material storage tank 2 closer to each other than the distance between the other abutting plates 65 positioned at the uppermost end and the transfer chamber 57 (i.e., make the input pipe 56 positioned at the uppermost end and the transfer chamber 57 communicate);
when the material level in the material storage tank 2 is lowered and the lifting screw 67 is synchronously driven to rotate by the wire wheel 60 so as to drive the touch rod 66 to move downwards along the transfer cavity 57 (in the downward movement process of the touch rod 66, the touch rod 66 always touches the touch plate 65 at a plane position, so that the input tube 56 positioned above is always in a communication state with the transfer cavity 57), so that when the touch rod 66 is lowered to a position close to two input tubes 56 below, the touch rod 66 is slowly separated from the touch plate 65 positioned above, in the process, the touch rod 66 is not completely separated from the arc surface positioned at the lower end of the touch plate 65, and is already contacted with the arc surface positioned at the upper end of the touch plate 65 below (at this time, the two input tubes 56 are both in a communication state with the transfer cavity 57), with the continuous downward movement of the contact rod 66, after the contact rod is completely separated from the arc-shaped surface of the contact plate 65 located above (the input pipe 56 located above is not communicated with the transfer chamber 57), the heat transfer oil starts to enter the spiral heating pipe 55 through the input pipe 56 located below, and when the liquid level in the storage tank 2 drops to the height of the position where the third input pipe 56 is located, the following process is the same as above, which is not described herein;
it is to be noted here that: when the material consumption finishes in storage tank 2, this moment the floater 58 is located storage tank 2 bottom position and supports feeler lever 66 and also be located transit chamber 57 bottom position, when adding the material in our case storage tank 2, floater 58 upwards moves under the effect of material buoyancy and line wheel 60 realizes tightening up cotton rope 59 under the effect of torsional spring 61, the bar rotates along with line wheel 60's rotation synchronous drive lift screw 67, and then realize driving the effect of supporting feeler lever 66 and moving up in the same time along transit chamber 57, about the maximum of material can be added to storage tank 2, technical staff in the field is carrying out real-time, can carry out corresponding adjustment according to actual demand.
The asphalt pavement filling and sealing machine can adjust the number of downward-pouring sealant spraying pipes 8 in real time according to the width of a pavement crack, namely, the amount of the downward-pouring sealant is adjusted, compared with the traditional mode that only a single discharging pipe discharges materials, the pavement crack repairing efficiency is greatly improved, and by arranging the deviation correcting device, the positions of the spraying pipes 8 relative to the crack can be adjusted in real time, so that the crack pouring materials poured out of the spraying pipes 8 can be poured into the crack, the situation that the spraying pipes 8 are not aligned with the crack due to the uncertainty of manual visual observation is avoided, the crack pouring materials are poured onto the pavement beside the crack is further avoided, the automation degree of the whole process is high, and the work burden of constructors is greatly reduced;
preferably, in order to reduce the consumption of heat energy in this scheme, we will set up the spiral heating pipe 55 in the wall of storage tank 2 and have a transfer chamber 57 through the input tube 56 intercommunication that a plurality of vertical intervals set up, we are provided with a plurality of connecting valves at the vertical interval in transfer chamber 57, and then realize opening corresponding connecting valve according to the height of the material level of the interior crack pouring material of storage tank, make heating oil no longer flow through the spiral heating pipe 55 that is located crack pouring material level top, thereby realized reducing the effect of heat energy consumption, and is better, as an optimization, we can be at transfer section of thick bamboo 6, spray pipe 8, set up the heating fuse in the intermediate pipe 9 inner wall and realize the power supply through external power supply, so that the pouring sealant that gets into to transfer section of thick bamboo 6, spray pipe 8, intermediate pipe 9 still is in the temperature that accords with the demand.
