Description

Technical Field

[0001] The invention belongs to the technical field of asphalt pavement maintenance, in particular to a preventive maintenance device for epoxy asphalt pavement. Background Art

[0002] Unlike thermoplastic asphalt, epoxy asphalt is a thermosetting material that does not have self-healing properties. Therefore, its primary diseases usually include cracks and bumps. If these small cracks are not promptly and effectively treated, the cracks will expand rapidly and turn into structural damage such as pits. In this case, preventive maintenance will not be able to repair them. Therefore, it is very important to control the development trend of original diseases such as cracks in a timely manner.

[0003] Existing preventive maintenance measures for epoxy asphalt pavement include cleaning cracks and directly pouring epoxy resin into them for penetration. However, it is very troublesome to clean the stubborn impurities deposited in the cracks, and it is relatively difficult to clean and grout the oblique cracks. Alternatively, the damaged parts can be lowered by grinding and then closed repairs can be performed again. However, existing repair devices mostly use the pouring method, and the thinning of the paved surface at the damaged parts and re-paving require multiple steps to be split for treatment. The preventive maintenance device proposed in this application is intended to centrally handle thinning, coating and spreading, improve efficiency and accuracy, and ensure project quality. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a preventive maintenance device for epoxy asphalt paving.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A preventive maintenance device for epoxy asphalt paving, comprising a main frame and a glue bucket and a fluid pump arranged thereon, and further comprising:

[0006] Working unit, which is used to grind the paved surface.

[0007] The driving mechanism 1 and the driving mechanism 2 are used to drive the working unit to move in a two-dimensional horizontal plane.

[0008] The suction device is arranged on the main frame and is used to suck the paving dust from the grinding through the working unit.

[0009] A crushed stone holding tank is provided on the main frame and is used to spread crushed stones on the area coated with the value after grinding by the working unit;

[0010] The working unit includes an angle grinder for grinding the paved surface, and a secondary working unit for sucking dust from the paved surface, applying epoxy resin glue and spreading gravel, and the secondary working units are connected to the glue bucket and the suction device respectively.

[0011] Preferably, the working unit also includes a motor and a turbine mechanism, the turbine mechanism bearing is connected to the top of the angle grinder, the turbine mechanism includes an axle seat rotatably connected to the angle grinder, and the motor is transmission-connected to the turbine mechanism for driving the angle grinder to rotate circumferentially around the axle seat.

[0012] Preferably, the working unit also includes an adjusting rod threadedly mounted on the two sliders of the driving mechanism, the bottom end of the adjusting rod is hingedly connected to a connecting frame mounted on the axle seat, a bearing is provided on the adjusting rod so that the adjusting rod can rotate circumferentially relative to the connecting frame, and the adjusting rod also includes a handwheel arranged on the top thereof for rotating itself to control the lifting and lowering of the angle grinder.

[0013] Preferably, the working unit further comprises a guiding mechanism for maintaining the vertical movement of the angle grinder, wherein the guiding mechanism comprises a sliding groove and a sliding rail that slide together, wherein the sliding groove is fixedly mounted on a slider of the second driving mechanism, and the sliding rail is fixedly connected to a connecting frame.

[0014] Preferably, the working end of the angle grinder is tilted downward by - degrees, and the tilt angle of the angle grinder is adjusted by a hinge, and the angle is limited by locking a nut.

[0015] Preferably, a slider is fixedly mounted on the motor, and the slider cooperates with a slide rail on the fixed plate to carry the motor to move in a vertical direction.

[0016] Preferably, the gravel storage tank is horizontally arranged on the top of the main frame, and a plurality of discharge doors are arranged at equal intervals for discharging the gravel inside, and the discharge doors are in a normally closed state;

[0017] The discharge door comprises a self-resetting lever located outside and a valve plate coaxially matched with the self-resetting lever, and the valve plate is used to control the passage of crushed stone discharge.

[0018] Preferably, a temporary storage bin is provided on the side of the working unit facing the gravel holding tank. When the temporary storage bin moves toward the unloading door, it can resist the self-resetting lever so that it drives the valve plate to rotate and unload so that the gravel is loaded into the temporary storage bin. The temporary storage bin is connected to the secondary working unit for spreading the gravel.

[0019] Preferably, the secondary working unit includes an exhaust box, a glue coating port and a spreading port. The exhaust box is connected to the suction device for sucking the paving dust polished by the angle grinder, the glue coating port is connected to the glue bucket for applying epoxy resin glue to the paving surface, and the spreading port is connected to the temporary storage bin for spreading gravel.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention uses an angle grinder that can move in a two-dimensional plane to thin the damaged area, reduce the height of the paved surface at the original damaged area, and then use an exhaust box to remove dust and other impurities in it. After ensuring that the thinned area is clean, epoxy resin glue is applied downward, which is specifically a fiber-reinforced resin. After the resin glue is completely infiltrated, the crushed stone is spread on the resin glue through a spreading port. The process can be operated in a streamlined manner, greatly reducing the split interval of the process, with high efficiency and high quality.

[0022] When the present invention drives the working unit to move toward the side where the gravel holding tank is located on the horizontal plane through the driving mechanism 1 and the driving mechanism 2, the outer surface of the temporary storage bin can contact the front of the self-resetting lever, thereby pushing the self-resetting lever to flip the valve plate inside the discharge door. After the valve plate flips, the discharge door is opened to spread the gravel therein. Since the discharge doors are evenly arranged at equal intervals, and the distance between two adjacent discharge doors is less than or equal to the length of the spreading port, when spreading gravel on the pavement in a plane, it can be ensured that no matter where it is in the lateral direction of the gravel holding tank, it can be loaded with gravel when moving toward it, which is convenient to operate, reduces the stroke of the working unit, and improves efficiency and speed.

DETAILED DESCRIPTION

[0033] 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.

[0034] like Figures 1 to 9 As shown, the present invention provides a preventive maintenance device for epoxy asphalt paving, comprising a main frame 100, a glue bucket 200 and a fluid pump 300 arranged thereon, and further comprising:

[0035] The working unit 800 is used to grind the paved surface.

[0036] The driving mechanism 1 600 and the driving mechanism 2 700 are used to drive the working unit 800 to move in a two-dimensional horizontal plane.

[0037] The suction device 400 is arranged on the main frame 100 and is used to suck the paving dust from grinding through the working unit 800.

[0038] A gravel storage tank 500 is provided on the main frame 100 and is used to spread gravel on the area coated with the value after grinding by the working unit 800;

[0039] The working unit 800 includes an angle grinder 801 for grinding the paved surface, and a secondary working unit 806 for sucking dust from the paved surface, applying epoxy resin glue and spreading gravel. The secondary working unit 806 is connected to the glue bucket 200 and the suction device 400 respectively.

[0040] The working unit 800 is used to grind and treat the diseased pavement. It is equipped with an angle grinder 801 for grinding the pavement, and a secondary working unit 806 for sucking the dust from grinding, applying epoxy resin glue, and spreading gravel after applying the glue. The work of the working unit 800 requires movement on the pavement surface in a two-dimensional plane. This work is completed by the driving mechanism 1 600 and the driving mechanism 2 700, which are used for driving and controlling in the X and Y axis directions respectively. The pavement surface is ground by the angle grinder 801 to reduce its height by about 1-2mm. After cleaning its surface, epoxy resin glue, which is a fiber-reinforced resin, is applied on the polished pavement surface. After the penetration is completed, gravel is sprinkled and filled.

[0041] like Figure 5 As shown, the working unit 800 also includes a motor 802 and a turbine mechanism 803. The turbine mechanism 803 is bearing-connected to the top of the angle grinder 801. The turbine mechanism 803 includes a shaft seat 8031 ​​rotatably connected to the angle grinder 801. The motor 802 is transmission-connected to the turbine mechanism 803 for driving the angle grinder 801 to rotate circumferentially around the shaft seat 8031.

[0042] It is used to drive the angle grinder 801 to rotate through the motor 802 and the turbine mechanism 803 when the direction of the angle grinder 801 needs to be adjusted as the grinding process continues, so that the direction in which the rotating grinding wheel of the angle grinder contacts the pavement is changed, thereby adaptively changing the posture of the blind spots where the working unit 800 moves, or positions on the pavement that are not convenient for grinding.

[0043] like Figure 5 and 7 As shown, the working unit 800 also includes an adjusting rod 804 threadedly mounted on the slider of the driving mechanism 2 700, the bottom end of the adjusting rod 804 is hinged to a connecting frame mounted on the shaft seat 8031, a bearing 8042 is provided on the adjusting rod 804 so that the adjusting rod 804 can rotate circumferentially relative to the connecting frame, and the adjusting rod 804 also includes a handwheel 8041 arranged on the top thereof for rotating itself to control the lifting and lowering of the angle grinder 801.

[0044] The angle grinder 801 is adjusted to rise and fall by turning the hand wheel 8041, and the angle grinder 801 itself is limited, and the adjusting rod 804 is also provided with a bearing 8042 for isolating the torque, so the adjusting rod 804 will not affect the circumferential posture of the angle grinder 801 when it rotates, and due to the threaded meshing action of the adjusting rod 804, it can only drive the angle grinder 801 to rise and fall in the vertical direction. The hand wheel 8041 set at the top is used for manual adjustment, and the height of the angle grinder 801 can be preset in advance according to the depth of grinding required by the angle grinder on site before work. The hand wheel 8041 here can also be replaced by a motor to drive the control mechanism, but the adjustment mechanism is the same.

[0045] like Figure 5 and 8 As shown, the working unit 800 also includes a guide mechanism 807 for maintaining the vertical movement of the angle grinder 801. The guide mechanism 807 includes a sliding groove 8071 and a sliding rail 8072 that slide together. The sliding groove 8071 is fixed on the slider of the driving mechanism 2 700, and the sliding rail 8072 is fixed on the connecting frame.

[0046] The guide mechanism 807 is a set of slidable mechanisms consisting of a slide groove 8071 and a slide rail 8072. In the horizontal direction, the slide groove 8071 limits the slide rail 8072 so that it can only slide in the vertical direction, and is used to form stable support and limit the working unit 800 through the slide rail 8072.

[0047] like Figure 5 As shown, the working end of the angle grinder 801 is tilted downward by 1-2 degrees. The tilt angle of the angle grinder 801 is adjusted by a hinge 8043 and the angle is limited by locking a nut.

[0048] The main purpose of this setting is to make it easier to polish the pavement. The adjustment angle and whether the angle adjustment is needed should be determined according to the actual on-site use environment and needs. Personnel in the field can make flexible adjustments based on actual conditions.

[0049] like Figure 7 As shown, a slider 8021 is fixedly mounted on the motor 802, and the slider 8021 cooperates with the slide rail on the fixed plate to carry the motor 802 to move along the vertical direction.

[0050] The output end of the motor 802 cooperates with the turbine mechanism 803, and the two are always on the same horizontal plane. Since the adjustment rod 804 needs to drive the angle grinder 801 to rise and fall a short distance in the vertical direction, the amplitude of this rise and fall is usually within 10 mm, so the motor 802 needs to cooperate with the turbine mechanism 803 to be able to rise and fall synchronously. Therefore, the motor 802 is not fixed on the fixed plate. It is connected to the main shaft through a waist hole to cooperate with the turbine mechanism 803. The sliders 8021 arranged on both sides can make it slide stably in the vertical direction, thereby playing a role in height adjustment.

[0051] like Figure 2 As shown, the gravel storage tank 500 is horizontally arranged on the top of the main frame 100, and a plurality of discharge doors 501 are evenly arranged to discharge the gravel inside, and the discharge doors 501 are normally closed;

[0052] The discharge door 501 includes a self-resetting lever 502 located outside and a valve plate 503 coaxially matched with the self-resetting lever 502. The valve plate 503 is used to control the opening and closing of the crushed stone discharge.

[0053] The main purpose of setting the gravel holding tank 500 horizontally is to facilitate its unloading. Several unloading doors 501 are evenly spaced below it to facilitate unloading at any horizontal position. Since the working unit 800 is in motion, the gravel is small but not in a fluid state, so it is very easy to cause material jamming during transportation by using a pipe connection. Therefore, the design of the gravel holding tank 500 in a horizontal direction and the corresponding discharge structure can effectively avoid the defect of material jamming during transportation, thereby ensuring the normal working process of the working unit 800.

[0054] like Figure 5 and 6 As shown, a temporary storage bin 805 is provided on the side of the working unit 800 facing the gravel holding tank 500. When the temporary storage bin 805 moves toward the discharge door 501, it can resist the self-resetting lever 502, so that it drives the valve plate 503 to rotate and discharge, so that the gravel is loaded into the temporary storage bin 805. The temporary storage bin 805 is connected to the secondary working unit 806 for spreading the gravel.

[0055] When the working unit 800 is driven by the driving mechanism 1 600 and the driving mechanism 2 700 to move on the horizontal plane toward the side where the gravel holding tank 500 is located, the outer surface of the temporary storage bin 805 can be in front contact with the self-resetting lever 502, thereby pushing the self-resetting lever 502 to flip the valve plate 503 inside the discharge door 501. After the valve plate 503 flips, the discharge door 501 is opened to spread the gravel therein. Since the discharge doors 501 are evenly arranged at equal intervals, and the distance between two adjacent discharge doors 501 is less than or equal to the length of the spreading port 8063, when spreading gravel on the pavement in a plane, it can be ensured that no matter where it is in the horizontal direction of the gravel holding tank 500, it can be loaded with gravel when moving toward it.

[0056] like Figure 8-9 As shown, the secondary working unit 806 includes an exhaust box 8061, a glue application port 8062 and a spreading port 8063. The exhaust box 8061 is connected to the suction device 400 for sucking the paving dust polished by the angle grinder 801, the glue application port 8062 is connected to the glue bucket 200 for applying epoxy resin glue to the paving surface, and the spreading port 8063 is connected to the temporary storage bin 805 for spreading gravel.

[0057] The secondary working unit 806 integrates the three working units of the vacuum box 8061, the glue coating port 8062 and the spreading port 8063 together for unified movement and coordination. The vacuum box 8061 is in a semi-wrapped state, which is used to suck the grinding dust on the pavement. It can also play a good dust suction role when coating resin colloid and spreading gravel, thereby ensuring the purity of the vertical colloid and removing debris from the pavement to reduce the cavitation rate of the colloid.

[0058] The working principle and use process of the present invention:

[0059] The position of the working unit 800 on the horizontal plane is controlled by driving mechanism 1 600 and driving mechanism 2 700. The height of the angle grinder 801 on the working unit 800 is adjusted by adjusting rod 804, so that it is lowered to a preset position at the gap of the pavement surface, and then grinding is started. During grinding, dust is sucked out by the exhaust box 8061, and impurities and the like on the pavement surface are cleaned after grinding is completed.

[0060] After thinning is completed, inject epoxy resin glue into the polished paving surface. After the colloid is completely penetrated and the liquid level no longer drops, evenly spread gravel on it to level it.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0062] 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.
