Description

Technical Field

[0001] The invention belongs to the field of road surface repair, in particular to a road surface repair device. Background Art

[0002] The current road burden is becoming increasingly heavy. Different types of vehicles are traveling on the same roads, which puts great pressure on the road surface. Once daily maintenance cannot keep up in time, the roads will become riddled with holes over time, seriously threatening driving safety.

[0003] A patent application with publication number CN109629387A discloses a road repair vehicle, comprising a vehicle body, a cleaning mechanism arranged at the bottom of the vehicle body, a filling mechanism arranged on the vehicle body, and a flattening mechanism arranged on the vehicle body, wherein the cleaning mechanism comprises an air nozzle rotatably arranged at the bottom of the vehicle body. The invention has the effect of cleaning dust in the road repairing part to improve the connection strength between concrete and foundation.

[0004] The functions of traditional road repair devices are relatively simple. When repairing the road surface, the area that needs to be repaired must first be fenced off to temporarily block the passage of vehicles. Then the road surface that needs to be repaired must be cleaned and repaired, resulting in the usable area of ​​the road being occupied for a long time. This not only affects the normal use of the road, but also after the road surface is damaged, it will take a long time from discovering the damage to deciding on the repair plan and finally to repairing the road surface. The damage to the road surface will gradually expand during the driving of the vehicle. At the same time, the damaged road surface will also affect the driving safety of the vehicle.

[0005] To this end, the present invention provides a road surface repairing device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a road repair device described in the present invention includes a protection frame, the four corners of the protection frame are equipped with electric wheels, the front end of the protection frame is equipped with two optical probes, the inner side of the protection frame is provided with a drill bit that can rotate and move up and down, the drill bit is made of elastic material, an absorption component is provided above the drill bit, the absorption component is used to absorb broken road surface materials, the inner side of the protection frame is also provided with a filling component, the filling component is used to fill the repair material into the road surface defects, and warning lights are installed around the protection frame;

[0008] Through the setting of the protection frame and the optical probe 1, the protection frame can travel on the road surface driven by the electric wheel, and the optical probe 1 can be used to scan and observe whether the road surface is damaged. A solar panel can be installed on the top of the protection frame to provide the equipment with sufficient power. When damage is found, the electric wheel drives the protection frame to move above the road damage and turns on the warning lights around it; the operation can be carried out until night when there is less traffic; then the loose material of the damaged part is ground by a rotatable drill bit, and then the dust, gravel and ground material are sucked into it by the absorption component, and then the repair material is filled into the gap by the filling component. After the material solidifies, the road surface is repaired. It should be noted that this is a preliminary treatment of the road surface and cannot achieve the function of long-term use. The effect is that when damage is found on the road surface, timely repair measures can be taken on the road surface, which can not only reduce the further expansion of the damage, but also the passing vehicles will not have a noticeable bumpy feeling when passing by, which greatly reduces the safety hazards of the road surface.

[0009] Preferably, the filling component includes an electric heating box, the interior of the electric heating box is filled with hot-melt material, a transmission pump is fixedly connected to the bottom output end of the electric heating box, and optical probes 2 are installed at the four inner corners of the protective frame. The electric heating box stores hot-melt material, which may be resin and hot-melt adhesive material. Fiber material is also added to the material. In order to improve the integrity of the material, when the transmission pump moves to the top of the damaged part of the road surface, the electric heating box heats the internal hot-melt material to melt it, and the material is injected into the damaged part through the transmission pump. The injected amount is observed by optical probe 2, and the filling is terminated when the material is flush with the road surface. As the material is discharged, the temperature drops rapidly, and the material will solidify and combine with the road surface. In this way, it can play an effect of emergency treatment of road damage. The highest temperature of the road surface is about 70 degrees Celsius, which is not enough to melt the hot-melt material.

[0010] Preferably, a support plate is fixedly connected to the top of the protection frame, a vacuum pump is fixedly connected to the top of the support plate, an outer sleeve is provided on the top of the drill bit, a hose is connected between the outer sleeve and the vacuum pump, and the bottom of the outer sleeve is connected to the inner side of the drill bit. During the operation of the drill bit, the vacuum pump is started to produce negative pressure, and the negative pressure enters into the interior of the drill bit through the hose and the outer sleeve, thereby sucking the road surface material and gravel and other materials generated by the rotation into the vacuum pump for storage. A filter bag is provided in the vacuum pump for temporarily storing materials.

[0011] Preferably, the drill bit is composed of two arc-shaped drill bars, which are arranged in a cross shape and fixed to each other at the bottom. A plurality of protruding friction heads are fixed to the outer side of the drill bar. The drill bar is formed by bending an elastic metal sheet, and the outer side of the metal sheet is covered with a protective layer of elastic wear-resistant material. When the drill bit contacts the road damage, the drill bar will deform moderately. The work of the drill bar is simply to grind the edge of the damage, and does not require a large power. With the setting of the friction head, the damaged area can be better rubbed, allowing the material that has lost its effect to fall off, and at the same time, gravel particles that fall into the damage can be removed. The material of the drill bar can be bent and deformed moderately. During the rotational contact process, it can rub the inside of the damaged area well, and can also return to its original state when not working.

[0012] Preferably, a connecting frame is fixedly connected between the tops of the two drill rods, the middle part of the connecting frame is through-set, the top of the connecting frame is connected to an inner sliding tube, the inner sliding tube is slidably clamped on the inner side of the outer sleeve, and two electric telescopic rods 1 are fixedly connected to the outer side of the inner sliding tube, and the bottom output end of the electric telescopic rod 1 is fixedly connected to the outer side of the inner sliding tube, and the inner sliding tube is driven to slide out and retract downward by extending and shortening the two electric telescopic rods 1, so that the bottom height of the drill bit can be controlled, so that the drill bit will not touch the ground when the equipment moves, and can work deep into the road damage during friction operation.

[0013] Preferably, the middle part of the top end of the outer sleeve protrudes upward, the hose is connected to the outer side of the outer sleeve near the top, a fixed plate is arranged above the outer sleeve, a reduction motor is fixedly connected to the fixed plate, the output end of the reduction motor is fixedly connected to the top of the outer sleeve, and a support frame is fixedly connected between the fixed plate and the support plate. In order to facilitate the drill bit to act on the damaged area in a larger range during grinding, the outer sleeve and the drill bit are driven to rotate by the reduction motor so that the drill bit can swing to both sides. In this way, when dealing with damage with a larger area, the drill bit can be swung and the length of the electric telescopic rod can be controlled at the same time, so that the drill bit is always in contact with the damaged area. At the same time, the equipment moves forward, so that the drill bit can rub the entire damaged area relatively quickly, thereby improving the processing efficiency.

[0014] Preferably, an absorption cover is fixedly connected to the middle part of the connecting frame, the bottom end of the absorption cover is located on the inner side of the drill bit, and the top of the absorption cover is fixedly connected to the inner sliding tube. In order to improve the absorption effect, the absorption cover is located inside the drill bit, and the drill rod will not touch the absorption cover within the maximum deformation range. The absorption cover concentrates the suction force of the vacuum pump in the drill bit, so that the material generated by the friction process can be directly absorbed into the vacuum pump.

[0015] Preferably, the outer side of the bottom of the absorption hood is arranged in an outwardly expanded shape, the top of the absorption hood is fixedly connected to a gear ring, the outer side of the inner sliding tube is fixedly connected to a driving motor, the bottom output end of the driving motor is fixedly connected to a gear plate, the gear plate and the gear ring are meshed with each other, and the driving motor drives the gear plate to rotate, thereby driving the overall drill bit, the connecting frame and the absorption hood to rotate together, completing the effect of grinding the damaged part of the drill bit, and the expanded shape of the outer side of the absorption hood can better absorb materials such as gravel on the side.

[0016] Preferably, two electric telescopic rods 2 are fixedly connected to the outer side of the transmission pump, and the bottom output end of the transmission pump is slidably connected with a delivery pipe. The bottom movable end of the electric telescopic rod 2 is fixedly connected to the delivery pipe. When the drill bit is polished, the equipment is moved, and the delivery pipe is moved to the top of the damaged area through observation by the optical probe 2. The delivery pipe is pushed downward by the electric telescopic rod 2, so that the raw material at the bottom of the delivery pipe can slowly fill the road damage, and the delivery pipe slowly rises until the damaged area is filled with the raw material.

[0017] Preferably, one side of the transmission pump is rotatably connected to a power box, one side of the power box is fixedly connected to a vibrating rod, the power box is used to provide power to the vibrating rod, one end of the vibrating rod penetrates into the inner side of the delivery pipe, a motor is installed on the inner side of the transmission pump, and a cable is connected between the power box and the output end of the motor. During the filling process, the vibrating rod will also fall into the damaged area, and the power box is started to allow the vibrating rod to vibrate so that the injected repair material can better flatten the damaged area. When the filling is completed, the motor reels in the cable to rotate the power box to a horizontal position, and the vibrating rod will rub against the delivery pipe to remove the hot melt adhesive on the surface, allowing the next work to proceed normally. During the next work, the hot melt adhesive will be injected downward from the delivery pipe, which will heat the surface of the vibrating rod and cause the hardened hot melt adhesive to fall off.

When damage is found, the electric wheel drives the protection frame to move above the road surface damage and turns on the warning lights around it; the operation can be carried out when there is less traffic at night; then the loose material of the damaged part is ground by a rotatable drill bit, and then dust, gravel and ground material are sucked into it by an absorption component, and then the repair material is filled into the gap by a filling component. After the material solidifies, the road surface is repaired. It should be noted that this is a preliminary treatment of the road surface and cannot achieve the function of long-term use. The effect is that when damage is found on the road surface, the road surface can be repaired in time, which can not only reduce the further expansion of the damage, but also the passing vehicles will not have a significant bumpy feeling when passing by, which greatly reduces the safety hazards of the road surface.

[0020] 2. A road repair device described in the present invention stores hot-melt material in an electric heating box. The hot-melt material may be resin and hot-melt adhesive material. Fiber material is also added to the material. In order to improve the integrity of the material, when the transmission pump moves to the top of the damaged part of the road surface, the electric heating box heats the internal hot-melt material to melt it, and the material is injected into the damaged part through the transmission pump.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 5 As shown, a road repair device according to an embodiment of the present invention comprises a protection frame 1, electric wheels 3 are installed at the four corners of the protection frame 1, two optical probes 4 are installed at the front end of the protection frame 1, a drill bit 8 that can rotate and move up and down is arranged on the inner side of the protection frame 1, the drill bit 8 is made of elastic material, an absorption component is arranged above the drill bit 8, the absorption component is used to absorb broken road surface materials, a filling component is also arranged on the inner side of the protection frame 1, the filling component is used to fill the repair material into the road surface defects, and warning lights are installed on all sides of the protection frame 1;

[0032] When working, the traditional road repair device has a relatively simple function. When repairing the road, the area to be repaired must be fenced off first to temporarily block the passage of vehicles, and then the road to be repaired must be cleaned and repaired, resulting in the usable area of ​​the road being occupied for a long time, which not only affects the normal use of the road, but also after the road is damaged, it will take a long time from discovering the damage to deciding on the repair plan and finally repairing the road. The damage to the road will gradually expand during the driving of the vehicle, and the damaged road will also affect the driving safety of the vehicle;

[0033] By setting the protection frame 1 and the optical probe 4, the protection frame 1 can travel on the road surface driven by the electric wheel 3, and the optical probe 4 can be used to scan and observe whether the road surface is damaged. A solar panel can be installed on the top of the protection frame 1 to provide the equipment with sufficient power. When damage is found, the electric wheel 3 drives the protection frame 1 to move above the road surface damage and turns on the warning lights around it; the operation can be carried out until night when there is less traffic; then the loose material of the damaged part is grinded by the rotatable drill bit 8, and then the dust, gravel and grinded material are sucked into it by the absorption component, and then the repair material is filled into the gap by the filling component. After the material solidifies, the repair of the road surface is completed. It should be noted that this is a preliminary treatment of the road surface and cannot achieve the function of long-term use. The effect is that when damage is found on the road surface, timely repair measures can be taken on the road surface, which can not only reduce the further expansion of the damage, but also the passing vehicles will not have a significant bumpy feeling when passing by, which greatly reduces the safety hazards of the road surface.

[0034] like Figures 1 to 5 As shown, the filling assembly includes an electric heating box 5, the interior of the electric heating box 5 is filled with hot-melt material, a transmission pump 24 is fixedly connected to the bottom output end of the electric heating box 5, and optical probes 29 are installed at the four inner corners of the protection frame 1;

[0035] During operation, the electric heating box 5 contains hot-melt material, which may be resin and hot-melt adhesive material, and fiber material is also added to the material. In order to improve the integrity of the material, when the transmission pump 24 moves to the top of the damaged part of the road surface, the electric heating box 5 heats the internal hot-melt material to melt it, and injects the material into the damaged part through the transmission pump 24. The amount of injection is observed by the optical probe 29, and the filling is completed when the material is flush with the road surface. As the material is discharged, the temperature drops rapidly, and it will solidify and combine with the road surface, so that it can play an emergency role in treating road damage. The maximum temperature of the road surface is about 70 degrees, which is not enough to melt the hot-melt material.

[0036] like Figures 1 to 5 As shown, a support plate 10 is fixedly connected to the top of the protection frame 1, a vacuum pump 2 is fixedly connected to the top of the support plate 10, an outer sleeve 7 is provided on the top of the drill bit 8, a hose 20 is connected between the outer sleeve 7 and the vacuum pump 2, and the bottom of the outer sleeve 7 is connected to the inner side of the drill bit 8;

[0037] During operation, when the drill bit 8 is working, the vacuum pump 2 is started to produce negative pressure, and the negative pressure enters the interior of the drill bit 8 through the hose 20 and the outer sleeve 7, thereby sucking the road surface material and gravel and other materials generated by the rotation into the vacuum pump 2 for storage. The vacuum pump 2 is provided with a filter bag for temporarily storing materials.

[0038] like Figures 1 to 5As shown, the drill bit 8 is composed of two arc-shaped drill bars 11, which are arranged in a cross shape and fixed to each other at the bottom. A plurality of protruding friction heads 12 are fixed to the outside of the drill bars 11. The drill bars 11 are formed by bending an elastic metal sheet, and the outside of the metal sheet is covered with a protective layer of elastic wear-resistant material.

[0039] During operation, when the drill bit 8 contacts the road surface damage, the drill rod 11 will be deformed appropriately. The work of the drill rod 11 is simply to grind the edge of the damage, which does not require a large power. With the setting of the friction head 12, the damaged area can be rubbed better, allowing the material that has lost its effect to fall off, and at the same time remove the gravel particles that fall into the damage. The material of the drill rod 11 can be bent and deformed appropriately. During the rotational contact process, it can rub the inside of the damaged area well, and it can also return to its original state when not working.

[0040] like Figures 1 to 5 As shown, a connecting frame 13 is fixedly connected between the tops of the two drill bars 11, the middle part of the connecting frame 13 is through-set, the top of the connecting frame 13 is connected with an inner sliding tube 15, the inner sliding tube 15 is slidably clamped on the inner side of the outer sleeve 7, and the outer side of the inner sliding tube 15 is fixedly connected with two electric telescopic rods 16, and the bottom output end of the electric telescopic rod 16 is fixedly connected to the outer side of the inner sliding tube 15;

[0041] During operation, the inner slide tube 15 is driven to slide out and retract downward by extending and shortening the two electric telescopic rods 16, so that the bottom height of the drill bit 8 can be controlled, so that the drill bit 8 will not touch the ground when the equipment moves, and can work deeply into the road damage during friction operation.

[0042] like Figures 1 to 5 As shown, the middle part of the top of the outer sleeve 7 protrudes upward, the hose 20 is connected to the outer side of the outer sleeve 7 near the top, a fixing plate 18 is arranged above the outer sleeve 7, a reduction motor 17 is fixedly connected to the fixing plate 18, the output end of the reduction motor 17 is fixedly connected to the top of the outer sleeve 7, and a support frame 19 is fixedly connected between the fixing plate 18 and the support plate 10;

[0043] During operation, in order to facilitate the drill bit 8 to act on the damaged area in a larger range during grinding, the outer sleeve 7 and the drill bit 8 are driven to rotate by the reduction motor 17, so that the drill bit 8 can swing to both sides. In this way, when treating a large area of ​​damage, the drill bit 8 can be swung and the length of the electric telescopic rod 16 can be controlled at the same time, so that the drill bit 8 is always in contact with the damaged area. At the same time, the equipment moves forward, so that the drill bit 8 can rub the entire damaged area more quickly, thereby improving the treatment efficiency.

[0044] like Figures 3 to 7As shown, an absorption cover 23 is fixedly connected to the middle of the connecting frame 13, the bottom end of the absorption cover 23 is located inside the drill bit 8, and the top of the absorption cover 23 is fixedly connected to the inner sliding tube 15;

[0045] During operation, in order to improve the absorption effect, the absorption cover 23 is located inside the drill bit 8, and the drill rod 11 will not touch the absorption cover 23 within the maximum deformation range. The absorption cover 23 concentrates the suction force of the vacuum pump 2 in the drill bit 8, so that the material generated by the friction process can be directly absorbed into the vacuum pump 2.

[0046] like Figures 3 to 7 As shown, the outer side of the bottom of the absorption cover 23 is arranged in an outwardly expanded shape, the top of the absorption cover 23 is fixedly connected with a gear ring 21, the outer side of the inner sliding tube 15 is fixedly connected with a driving motor 14, the bottom output end of the driving motor 14 is fixedly connected with a gear plate 22, and the gear plate 22 and the gear ring 21 are meshed with each other;

[0047] During operation, the gear plate 22 is driven to rotate by the driving motor 14, thereby driving the entire drill bit 8, the connecting frame 13 and the absorption cover 23 to rotate together, thereby completing the effect of grinding the damaged part of the drill bit 8. The expanded setting of the outer side of the absorption cover 23 can better absorb materials such as gravel on the side.

[0048] like Figures 3 to 7 As shown, two electric telescopic rods 27 are fixedly connected to the outer side of the transmission pump 24, and the bottom output end of the transmission pump 24 is slidably connected with the delivery pipe 6, and the bottom movable end of the electric telescopic rod 27 is fixedly connected to the delivery pipe 6;

[0049] During operation, after the drill bit 8 has finished grinding, the equipment is moved, and through observation by the optical probe 29, the conveying pipe 6 is moved to the top of the damaged area, and the conveying pipe 6 is pushed downward by the electric telescopic rod 27, so that the raw material at the bottom of the conveying pipe 6 can slowly fill the road surface damage, and at the same time, the conveying pipe 6 slowly rises until the raw material fills the damaged area.

[0050] like Figures 3 to 7 As shown, one side of the transmission pump 24 is rotatably connected to a power box 25, one side of the power box 25 is fixedly connected to a vibrating rod 26, the power box 25 is used to provide power to the vibrating rod 26, one end of the vibrating rod 26 penetrates the inner side of the delivery pipe 6, a motor is installed on the inner side of the transmission pump 24, and a cable 28 is connected between the power box 25 and the output end of the motor;

[0051] During operation, during the filling process, the vibrating rod 26 will also fall into the damaged area, and the power box 25 will be started to allow the vibrating rod 26 to vibrate, so that the injected repair material can better flatten the damaged area. When the filling is completed, the motor reels in the cable 28, allowing the power box 25 to rotate to a horizontal position. The vibrating rod 26 will rub against the delivery pipe 6 to remove the hot melt adhesive on the surface, allowing the next work to proceed normally. During the next work, the hot melt adhesive will be injected downward from the delivery pipe 6, which will heat the surface of the vibrating rod 26 and cause the hardened hot melt adhesive to fall off.

[0052] During operation, through the setting of the protection frame 1 and the optical probe 4, the protection frame 1 can travel on the road surface driven by the electric wheel 3, and the optical probe 4 can be used to scan and observe whether the road surface is damaged. A solar panel can be installed on the top of the protection frame 1 to provide the equipment with sufficient power. When damage is found, the electric wheel 3 drives the protection frame 1 to move above the road surface damage and turns on the warning lights around it; the operation can be carried out until night when there is less traffic; then the loose materials of the damaged part are ground by the rotatable drill bit 8, and then the dust, gravel and ground materials are sucked into them by the absorption component, and then the repair material is filled into the gap by the filling component. After the material solidifies, the repair of the road surface is completed. It should be noted that this is a preliminary treatment of the road surface and cannot achieve the function of long-term use. The effect is that when damage is found on the road surface, the road surface can be repaired in time, which can not only reduce the further expansion of the damage, but also the passing vehicles will not have obvious bumps when passing by, which greatly reduces the safety hazards of the road surface;

[0053] The electric heating box 5 stores hot melt material, which can be resin and hot melt adhesive material. Fiber material is also added to the material. In order to improve the integrity of the material, when the transmission pump 24 moves to the top of the road surface damage, the electric heating box 5 heats the internal hot melt material to melt it, and injects the material into the damage through the transmission pump 24. The amount of injection is observed by the optical probe 29. When the material is flush with the road surface, the filling is completed. As the material is discharged, the temperature drops rapidly, and it solidifies and combines with the road surface. In this way, it can play an effect of emergency treatment of road surface damage. The maximum temperature of the road surface is about 70 degrees, which is not enough to melt the hot melt material.

[0054] During the operation of the drill bit 8, the vacuum pump 2 is started to produce negative pressure, and the negative pressure enters the interior of the drill bit 8 through the hose 20 and the outer sleeve 7, thereby sucking the road surface material and gravel and other materials produced by the rotation into the vacuum pump 2 for storage. The vacuum pump 2 is provided with a filter bag to temporarily store the materials;

[0055] When the drill bit 8 contacts the road surface damage, the drill bar 11 will be deformed appropriately. The work of the drill bar 11 is just to simply grind the edge of the damage, which does not require a large amount of power. With the setting of the friction head 12, the damaged part can be rubbed better, so that the material that has lost its effect can be peeled off, and the gravel particles that fall into the damage can be removed. The material of the drill bar 11 can be bent and deformed appropriately. During the rotating contact process, it can rub the inside of the damaged part very well, and it can also return to its original state when not working.

[0056] By extending and shortening the two electric telescopic rods 16, the inner slide tube 15 is driven to slide out and retract downward, so that the bottom height of the drill bit 8 can be controlled, so that the drill bit 8 will not touch the ground when the equipment moves, and can work deep into the road damage during friction work;

[0057] In order to facilitate the drill bit 8 to act on the damaged area in a wider range during grinding, the outer sleeve 7 and the drill bit 8 are driven to rotate by the reduction motor 17, so that the drill bit 8 can swing to both sides. In this way, when treating a large area of ​​damage, the drill bit 8 can be swung and the length of the electric telescopic rod 16 can be controlled at the same time, so that the drill bit 8 is always close to the damaged area. At the same time, the equipment moves forward, so that the drill bit 8 can rub the entire damaged area relatively quickly, thereby improving the treatment efficiency;

[0058] In order to improve the absorption effect, the absorption cover 23 is located inside the drill bit 8. The drill rod 11 will not touch the absorption cover 23 within the maximum deformation range. The absorption cover 23 concentrates the suction force of the vacuum pump 2 in the drill bit 8, so that the material generated during the friction process can be directly absorbed into the vacuum pump 2.

[0059] The gear plate 22 is driven to rotate by the driving motor 14, thereby driving the entire drill bit 8, the connecting frame 13 and the absorption cover 23 to rotate together, so as to complete the effect of grinding the damaged part of the drill bit 8. The expanded setting of the outer side of the absorption cover 23 can better absorb the gravel and other materials on the side;

[0060] When the drill bit 8 is finished grinding, the equipment is moved, and the conveying pipe 6 is moved to the top of the damaged part through the observation of the optical probe 2 9, and the conveying pipe 6 is pushed downward by the electric telescopic rod 27, so that the raw material at the bottom of the conveying pipe 6 can slowly fill the road surface damage, and the conveying pipe 6 slowly rises until the raw material fills the damaged part;

[0061] During the filling process, the vibrating rod 26 will also fall into the damaged area, and the power box 25 will be started to allow the vibrating rod 26 to vibrate, so that the injected repair material can better flatten the damaged area. When the filling is completed, the motor reels in the cable 28, allowing the power box 25 to rotate to a horizontal position. The vibrating rod 26 will rub against the delivery pipe 6 to remove the hot melt adhesive on the surface, allowing the next work to proceed normally. During the next work, the hot melt adhesive will be injected downward from the delivery pipe 6, which will heat the surface of the vibrating rod 26 and cause the hardened hot melt adhesive to fall off.
