Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance, in particular to a pavement crack filling device used for highway roadbed maintenance. Background Art

[0002] Highway repair and maintenance is an important part of highway maintenance work. It is of great significance to maintain the flatness of the highway, extend the service life of the highway and ensure driving safety. By timely repairing and maintaining the cracks in the road surface, it can effectively prevent the cracks from further expanding and reduce the erosion of moisture and impurities on the road surface, thereby extending the service life of the highway and providing safety for driving.

[0003] For example, a crack repair device for highway maintenance with publication number CN220986322U has a first connecting rod, a support rod, a round rod and a moving wheel. When an operator moves a caulking tube, the operator can drag the moving assembly on the ground. The moving wheel rolls on the ground, which makes it convenient for the operator to drag the caulking tube on the ground, saving the operator's physical strength, thereby improving the accuracy of caulking.

[0004] When the above device is in use, when facing some deeper cracks on the road, the dragged caulking tube moves with the moving wheels, and the overall movement depends on the signal transmitted when the staff looks directly at the cracks. When the moving wheels block the cracks where the caulking tube is located, a certain blind spot will appear. As a result, when filling cracks in some blind spots, the raw materials will often be partially sprayed on the ground because the filling tube is not directly above the cracks. This will not only cause a waste of raw materials, but also require the subsequent cleaning of the raw materials sprayed on the road. At the same time, the staff will be required to fill the area again, reducing the efficiency of the entire filling repair. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a pavement grouting device for highway roadbed maintenance, which can automatically adjust and position some deeper and larger highway cracks during the process of repairing such cracks, so that the grouting tube can always be kept directly above the crack, thereby improving the overall grouting efficiency and eliminating the need for staff to always observe the position of the grouting tube.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a pavement caulking device for roadbed maintenance, comprising a moving seat, a material storage tank is arranged on the moving seat, a motor is arranged on the moving seat, a caulking pipe is arranged on the material storage tank, and a bracket is arranged at one end of the caulking pipe away from the material storage tank, a positioning component is arranged on the bracket, and the positioning component is used to locate the cracks on the pavement when the bracket is placed on the ground; The positioning assembly includes a positioning pin arranged on the side of the bracket away from the caulking tube, a telescopic rod symmetrically arranged on the side of the bracket close to the positioning pin, and the telescopic rod and the positioning pin are on the same horizontal line, and also includes an L-shaped clamping plate arranged on the end of the telescopic rod away from the bracket, a sliding guide rail movably arranged on the end of the L-shaped clamping plate away from the telescopic rod, a fixed plate movably arranged on the sliding guide rail, and a fitting plate arranged on the end of the fixed plate away from the sliding guide rail.

[0007] Preferably, the fixing plate is symmetrically provided with matching holes, the bracket is movably provided with a plug-in plate, and the plug-in plate is symmetrically provided with engaging grooves on one side close to the telescopic rod, the telescopic rod is movably provided with a pressing block, which engages and slides with the engaging groove, and the outside of the telescopic rod is sleeved with a first spring.

[0008] Preferably, the positioning pin array is provided with a placement groove, and a multi-stage extension rod is arranged inside the placement groove, a push plate is arranged at one end of the multi-stage extension rod away from the positioning pin, and a second spring is sleeved outside the multi-stage extension rod.

[0009] Preferably, the bracket is provided with a vibration component, which is used to hammer the ground during the caulking process to cause the ground to vibrate slightly, so that the filling material can be more compact. The bracket is provided with a mounting seat on the side away from the plywood, and a handle is movably provided on the mounting seat. The handle is provided with an adjustment component, which is used to adjust the posture of the bracket so that the mouth of the caulking tube can be directly facing the crack.

[0010] Preferably, the vibration assembly includes a support column arranged on the bracket, a rotating gear ring movably arranged at one end of the support column away from the bracket, a corrugated guide rail arranged on the side of the rotating gear ring away from the support column, and hammer blocks arranged in an array on the corrugated guide rail.

[0011] Preferably, the vibration assembly also includes a motor arranged on the bracket, a rotating shaft arranged on one side of the motor, a matching gear arranged on the end of the rotating shaft away from the motor, the matching gear meshing with the rotating gear ring, and a power supply arranged on the bracket.

[0012] Preferably, a positioning plate is provided on one side of the bracket close to the rotating gear ring, locking rods are arranged in an array on the positioning plate, locking plates are symmetrically provided on the hammer block, and the locking plates are engaged and slidably engaged with the locking rods.

[0013] Preferably, a storage cylinder is provided on the movable seat.

[0014] Preferably, the adjustment assembly includes a support seat arranged on the bracket, an adjustment rod movably arranged on the support seat, a threaded sleeve movably arranged at one end of the adjustment rod away from the support seat, a threaded rod sleeved on the handle, and the threaded rod and the threaded sleeve are threadedly connected.

[0015] Preferably, a fixing rod is arranged in an array at one end of the threaded rod away from the bracket, and the fixing rod and the handle are not in contact with each other, and a rotating ring is arranged at one end of the fixing rod away from the threaded rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention positions the caulking tube arranged on the bracket just above the crack by means of the positioning needle and the two laminating plates. When the laminating plates are laminating the cracks, the resistance of the laminating plates can be transmitted to the hands of the staff through the handle, so that the staff can always ensure that the caulking tube is just above the crack, and the staff does not need to visually observe the position of the caulking tube, thus avoiding the waste of raw materials caused by the caulking tube spraying on the road when filling the cracks; 2. At the same time, the hammer block is engaged and slid by the provided corrugated guide rail to make the hammer block reciprocate and rise and fall. Under the lifting action of the hammer block, the road surface is struck, causing the struck road surface to vibrate slightly. Under the action of the vibration, the raw materials filled in the cracks are interfered with, and the air remaining inside the raw materials is vibrated out, making the entire filling more compact, improving the effect of the entire repair, and avoiding the air remaining in the raw materials causing the filler to be hollow. At the same time, the striking of the road surface is alternating, which can ensure the effect of the striking; 3. At the same time, when it is found that the posture of the bracket is not parallel to the road surface, the threaded sleeve on the threaded rod can be moved by rotating the rotating ring, so that the adjusting rod pulls the bracket to swing the angle. The bracket can adjust the posture under the action of the handle and the adjusting rod, so that it is finally parallel to the road surface, which is convenient for the subsequent filling of the cracks in the road surface. The bracket parallel to the road surface can make the nozzle of the caulking pipe perpendicular to the crack, which can not only ensure that the added raw materials will not affect the effect of the entire filling due to the spraying arc caused by the tilt of the nozzle, but also facilitate the normal discharge of the nozzle to ensure that the raw materials will not be blocked at the nozzle.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0029] See also Figures 1 to 6, which is the first embodiment of the present invention, provides a technical solution: a pavement caulking device for highway roadbed maintenance, comprising a mobile seat 1, a material storage tank 2 is arranged on the mobile seat 1, the material storage tank 2 is used to store raw materials used for pavement caulking, a motor 3 is arranged on the mobile seat 1, the motor 3 is used to provide power, a caulking pipe 4 is arranged on the material storage tank 2, and a bracket 5 is arranged at one end of the caulking pipe 4 away from the material storage tank 2, and the end of the caulking pipe 4 away from the material storage tank 2 is engaged with the bracket 5, when the bracket 5 drives the caulking pipe 4 to move, the caulking pipe 4 itself can rotate to adjust its own shape to avoid the caulking pipe 4 from twisting and affecting the overall conveying effect of the caulking pipe 4, the bracket 5 is used to fix and support the port of the caulking pipe 4, and the handle 8 arranged on the bracket 5 can make it more convenient for the staff to move the caulking pipe 4, and a positioning component 6 is arranged on the bracket 5, and the positioning component 6 is used to locate the cracks on the road surface when the bracket 5 is placed on the ground; The positioning assembly 6 includes a positioning pin 61 arranged on the side of the bracket 5 away from the caulking tube 4. The positioning pin 61 is used for the staff to use the caulking tube 4 to caulk the cracks in the road surface. The positioning pin 61 can save the staff from manually adjusting the position of the caulking tube 4 so that the filling material can be poured into the cracks. The telescopic rod 62 is symmetrically arranged on the side of the bracket 5 close to the positioning pin 61, and the telescopic rod 62 and the positioning pin 61 are on the same horizontal line. There is a section with a smaller diameter on the inner rod of the telescopic rod 62, which is used to have enough lifting space when the lower pressing block 622 is lifted and lowered. It also includes an L-shaped card plate 63 arranged on the end of the telescopic rod 62 away from the bracket 5. The L-shaped card plate 63 is L-shaped as a whole, and has a T-shaped bayonet at the end away from the telescopic rod 62, which is used to engage with the sliding guide rail 64. The L-shaped card plate 63 is engaged and slidably engaged with each other, and under the action of the T-shaped card slot, the movement of the sliding guide rail 64 will not deviate from the engaging relationship between the L-shaped card plate 63. The sliding guide rail 64 is movably arranged on the end of the L-shaped card plate 63 away from the telescopic rod 62. The sliding guide rail 64 is retractable and is used to extend the engaging length of the sliding guide rail 64 and the L-shaped card plate 63, so that the sliding guide rail 64 can maintain the engaging relationship with the L-shaped card plate 63 when it is displaced. The fixed plate 65 movably arranged on the sliding guide rail 64 has a kind of engaging and sliding relationship with the fitting plate 66. When the fitting plate 66 is squeezed by the positioning pin 61 and moves obliquely, the fixed plate 65 can slide in the opened slot, and the fixing plate 65 is limited by the lower pressing block 622 so that The fixing plate 65 maintains a vertically rising state, and the fixing plate 65 and the positioning pin 61 are in a parallel state. Two symmetrical matching holes 651 are opened on the fixing plate 65 to match with the pushing plate 613. After the fixing plate 65 rises to a predetermined position, the matching holes 651 on the fixing plate 65 can be directly plugged into the pushing plate 613, so that the pushing plate 613 can push the fixing plate 65 out under the elastic force of the second spring 614, thereby driving the fitting plate 66 fixedly connected to one end of the fixing plate 65 to move synchronously. The fitting plate 66 arranged at the end of the fixing plate 65 away from the sliding guide rail 64 is in a state where a straight plate is connected to an arc plate. A plurality of universal wheels are arranged in an array on the side of the straight plate away from the fixing plate 65, and the arc plate A ball bearing is provided on one side, so that when the staff puts down the bracket 5 and inserts the positioning pin 61 into the crack of the road surface, the straight plate on the bonding plate 66 will first contact the road surface. Under the influence of the overall gravity of the bracket 5, the bonding plate 66 will always be bonded to the road surface under the restriction of the road surface, and the arc plate provided will move laterally under the pressure of the positioning pin 61, and the positioning pin 61 will extend under the action of its own pressure, so that the bonding plate 66 will show an upward trend relative to the positioning pin 61. When contact occurs between the fixed plate 65 and the pushing plate 613, the bonding plate 66 can be pushed laterally, so that the arc plate surface of the bonding plate 66 can contact the inner wall of the crack. Under the action of the ball bearings provided on the arc plate, the friction between the bonding plate 66 and the crack is reduced.The entire movement is smoother, and when the device is not in use, the arc plate can protect the top of the positioning pin 61 and wrap the front end of the positioning pin 61 to prevent the staff from contacting the positioning pin 61 and causing injury. An auxiliary slide is installed on the side of the bonding plate 66 on the bracket 5 to ensure the stability of the overall movement. Several universal wheels are also set on this auxiliary slide to provide auxiliary function for the movement of the entire bracket 5.

[0030] The fixing plate 65 is symmetrically provided with matching holes 651, which penetrate the entire fixing plate 65, and the matching hole 651 is tapered on the side close to the positioning pin 61, so that when the pushing plate 613 is inserted into the matching hole 651, the tapered top block on the pushing plate 613 can be more conveniently inserted into the fixing plate 65 under the action of the tapered opening of the matching hole 651. The bracket 5 is movably provided with a plug-in plate 51, and the plug-in plate 51 is symmetrically provided with a snap-fitting groove 511 on the side close to the telescopic rod 62. The snap-fitting groove 511 is used to slide and snap-fit ​​with the lower pressing block 62, and the lower pressing block 622 can rise when it is squeezed by the fixing plate 65, so that the fixing plate 613 can be inserted into the fixing plate 65. The clamping plate 66 is fully unfolded to contact the cracks in the road surface. A pressing block 622 is movably provided on the telescopic rod 62, and is engaged and slidably engaged with the engaging groove 511. The pressing block 622 has a certain inclination arc, which is used to facilitate the fixed plate 65 to be squeezed along the inclined surface of the pressing block 622 when moving, so that the pressing block 622 can rise. A first spring 621 is sleeved on the outside of the telescopic rod 62. The first spring 621 is set between the bracket 5 and the pressing block 622, which is used to provide elastic force to the pressing block 622, so that when the fixed plate 65 is reset, the pressing block 622 can be reset under the action of the first spring 621 and drive the plug-in board 51 to descend at the same time.

[0031] The array of positioning pins 61 is provided with a placement groove 611, and a multi-stage extension rod 612 is arranged inside the placement groove 611. One end of the multi-stage extension rod 612 is fixedly connected to the positioning pin 61, and a push plate 613 is arranged at the end of the multi-stage extension rod 612 away from the positioning pin 61. When the plug-in board 51 is pushed out of the predetermined position by the fixed plate 65 and loses contact with the push plate 613, the push plate 613 will be inserted into the matching hole 651 in the fixed plate 65 under the action of the second spring 614, so that the fixed plate 65 is pushed under the action of the second spring 614 to squeeze the lower pressing block 622, so that the lower pressing block 622 rises, and the fixed plate 51 is pushed out of the predetermined position by the fixed plate 65. 65 drives the bonding plate 66 to expand outward and fit on the cracks in the road surface. A push plate 613 is provided at the end of the multi-stage extension rod 612 away from the positioning pin 61. A conical top block is provided on the push plate 613 near the plug-in plate 51. The conical top block can cooperate with the matching hole 651 on the fixed plate 65 to form a plug-in relationship, so that the push plate 613 pushes the fixed plate 65 to move under the action of the second spring 614, thereby driving the bonding plate 66 to move. A second spring 614 is provided on the outside of the multi-stage extension rod 612, and the second spring 614 is used to provide power to enable the push plate 613 to drive the fixed plate 65 to move.

[0032] A vibration component 7 is provided on the bracket 5, and the vibration component 7 is used to hammer the ground during the caulking process to make the ground vibrate slightly, so that the filling material can be more compact. A mounting seat 52 is provided on the side of the bracket 5 away from the bonding plate 66, and a handle 8 is movably provided on the mounting seat 52. The handle 8 is used for the convenience of the staff to hold and move the caulking tube 4. An adjustment component 9 is provided on the handle 8, and the adjustment component 9 is used to adjust the posture of the bracket 5 so that the pipe mouth of the caulking tube 4 can face the crack.

[0033] During use, the staff first pushes the movable seat 1 to move the entirety to the position to be filled, then removes the caulking tube 4 from the storage tube 11, and the staff holds the handle 8 and adjusts the adjustment component 9 to make the bracket 5 set at one end of the caulking tube 4 parallel to the ground, which is convenient for subsequent filling of road cracks. Then, when the bracket 5 is placed on the crack on the ground, the positioning pin 61 set will be inserted into the crack, and the lower surface of the bonding plate 66 will contact the ground. In the process of continuously applying pressure to the bracket 5 , the positioning pin 61 will be displaced downward relative to the fitting plate 66, and the displacement of the positioning pin 61 will squeeze the fitting plate 66 to open. At the same time, the applied pressure will cause the fixed plate 65 movably arranged on the fitting plate 66 to push the plug-in plate 51 to move, and the movement of the plug-in plate 51 will drive the lower pressing block 622 to move synchronously. When the plug-in plate 51 pushed by the fixed plate 65 is out of contact with the pushing plate 613, the conical top block on the pushing plate 613 will contact with the matching hole 651 opened on the fixed plate 65, so that the fixed plate 6 5 will be finally opened horizontally under the action of the second spring 614 set on one side of the pushing plate 613, so that the side wall of the bonding plate 66 contacts with the crack, forming a positioning effect, so that the staff can feel the resistance of the crack when pushing the bracket 5 to move, and position the caulking tube 4 just above the crack. After the bonding plate 66 is opened, the switch valve between the storage tank 2 and the caulking tube 4 is opened, so that the filled raw materials can be transported to the cracks of the road surface through the caulking tube 4. When the road surface is started to be caulked and repaired, the vibration component 7 is started to knock the road surface in the filling area, causing the road surface to vibrate slightly. This slight vibration can interfere with the raw materials transported to the cracks by the caulking tube 4, so that the air remaining in the raw materials is vibrated out, thereby improving the overall filling effect. After the road surface repair is completed, the bonding plate 66 is manually reset to wrap the positioning pin 61, and the reset of the bonding plate 66 will cause the plug-in board 51 to automatically reset under the action of the first spring 621, and then the bracket 5 is placed on the storage tube 11 to complete the entire caulking operation. Example 2

[0034] See also Figures 1 to 9 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: The vibration assembly 7 includes a support column 71 arranged on the bracket 5, and the support column 71 is used to engage and slide the rotating gear ring 72. Under the support provided by the support column 71 to the rotating gear ring 72, the rotation of the rotating gear ring 72 itself will not be affected. The rotating gear ring 72 is movably arranged on the support column 71 at the end away from the bracket 5. The rotating gear ring 72 is used to rotate under the drive of the matching gear 77, so that the rotating gear ring 72 can drive the corrugated guide rail 73 arranged on one side of the rotating gear ring 72 to rotate synchronously during the rotation process, so that the corrugated guide rail 73 pushes the hammer block 74 to hammer the ground, causing vibration to the ground. The corrugated guide rail 73 arranged on the side of the rotating gear ring 72 away from the support column 71, the inner track of the corrugated guide rail 73 also presents a The wavy shape of the wavy guide rail 73 is a wave shape. When the rotating gear ring 72 drives the wavy guide rail 73 to rotate, the wavy guide rail 73 will squeeze the hammer block 74 to make the hammer block 74 move downward, thereby hammering the ground to cause vibration. The hammer blocks 74 arranged in an array on the wavy guide rail 73 are engaged and slidable with the wavy guide rail 73. Under the rotation of the wavy guide rail 73, the wavy guide rail 73 will push the hammer block 74 to perform a reciprocating lifting and lowering motion. During the descent of the hammer block 74, one side of the hammer block 74 contacts the ground, and the contact process will cause a vibration effect on the ground. This slight vibration can interfere with the raw material transported into the crack by the caulking pipe 4, so that the residual air in the raw material will be vibrated out, thereby improving the filling effect of the entire raw material.

[0035] The vibration assembly 7 also includes a motor 75 arranged on the bracket 5, a rotating shaft 76 arranged on one side of the motor 75, and a matching gear 77 arranged on the end of the rotating shaft 76 away from the motor 75, and the matching gear 77 is meshed with the rotating gear ring 72. The matching gear 77 is used to rotate under the drive of the motor 75, so that the rotating gear ring 72 rotates synchronously during the rotation process. A power supply 78 is arranged on the bracket 5, and the power supply 78 is used to provide electrical energy.

[0036] A positioning plate 53 is provided on the side of the bracket 5 close to the rotating gear ring 72. The positioning plate 53 is used to position the hammer block 74 through the sliding engagement between the locking rod 54 and the locking plate 741 provided on the hammer block 74, so as to prevent the hammer block 74 from being displaced under the contact of the corrugated guide rail 73. The locking rods 54 are arranged in an array on the positioning plate 53, and the locking plates 741 are symmetrically arranged on the hammer block 74. The locking plates 741 and the locking rods 54 are engaged and slid. The engagement and sliding between the locking plates 741 and the locking rods 54 are used to limit the movement of the hammer block 74, so that the hammer block 74 will not be driven by the corrugated guide rail 73 when it is lifted up and down, causing the hammer block 74 to deviate from the current position.

[0037] The movable seat 1 is provided with a storage tube 11, which is used to store the caulking tube 4 after use to prevent the bracket 5 at the front end of the caulking tube 4 from being damaged.

[0038] During use, when the caulking tube 4 starts to transport raw materials to repair the cracks, the motor 75 is started by the power supply 78, so that the motor 75 drives the rotating shaft 76 to rotate, and the rotation of the rotating shaft 76 drives the matching gear 77 to rotate synchronously, so that the rotating gear ring 72 meshed with one side of the matching gear 77 rotates, and the rotation of the rotating gear ring 72 causes the corrugated guide rail 73 to push the hammer block 74 to perform reciprocating lifting and lowering motions, and the hammer block 74 creates a knocking effect on the ground in the process of contacting the ground. This knocking effect can cause the ground to shake slightly, thereby vibrating out the residual air in the raw material, thereby improving the filling effect of the entire raw material and making the overall repair effect better.

[0039] The remaining structures are the same as those of Example 1. Example 3

[0040] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that: The adjusting assembly 9 includes a support seat 91 arranged on the bracket 5, and an adjusting rod 92 movably arranged on the support seat 91. The adjusting rod 92 is used to change the posture of the bracket 5 under the drive of the threaded sleeve 93, so that the bracket 5 can be parallel to the ground, which is convenient for the caulking tube 4 to caulk and repair the cracks. The threaded sleeve 93 is movably arranged at one end of the adjusting rod 92 away from the support seat 91, and the threaded rod 94 is sleeved on the handle 8. The threaded rod 94 is threadedly connected with the threaded sleeve 93. The inside of the threaded rod 94 is a through cavity for being sleeved with the handle 8. The threaded sleeve 93 can be driven to move when the threaded rod 94 rotates. The moving threaded sleeve 93 will drive the adjusting rod 92 to be displaced, so that the bracket 5 rotatably connected to the other end of the adjusting rod 92 will change its posture.

[0041] A fixing rod 941 is arranged in an array at one end of the threaded rod 94 away from the bracket 5, and the fixing rod 941 and the handle 8 do not contact each other. A rotating ring 942 is arranged at one end of the fixing rod 941 away from the threaded rod 94. The rotating ring 942 is used to facilitate the staff to move the bracket 5 by holding the handle 8. When it is found that the overall posture of the bracket 5 is not good, the threaded rod 94 can be rotated by rotating the rotating ring 942. The rotation of the threaded rod 94 makes the threaded sleeve 93 move on the threaded rod 94, so that the adjustment rod 92 can adjust the posture of the bracket 5, which is convenient for the subsequent caulking operation.

[0042] When the staff holds the handle 8 and needs to adjust the posture of the bracket 5, the threaded rod 94 is driven to rotate by rotating the rotating ring 942. The threaded rod 94 and the handle 8 are fitted together to form a locking and rotating relationship, so that the threaded rod 94 will not affect the handle 8 when rotating, and the rotation of the threaded rod 94 will cause the threaded sleeve 93 to be displaced, and the displaced threaded sleeve 93 will drive the adjusting rod 92 to move. The movement of the adjusting rod 92 will adjust the posture of the bracket 5. Under the limit of the handle 8 and the adjusting rod 92, the finally adjusted bracket 5 can be parallel to the ground, and then the cracks in the road surface can be filled through the caulking tube 4 to complete the caulking and repair of the entire road surface.

[0043] The remaining structures are the same as those of embodiments 1 and 2.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
