Description
Technical Field
[0001] The utility model relates to the field of road crack repair, in particular to a road construction crack filling device. Background Art
[0002] The maintenance of road cracks includes using a caulking vehicle to fill the road cracks with a repair agent to achieve crack repair. Currently, there are various types of caulking vehicles, including convenient hand-held caulking vehicles and automatic control caulking vehicles with a high degree of automation. Automatic control caulking vehicles have high procurement costs and high maintenance costs; this type of caulking vehicle is not convenient for long-distance transportation, and the convenient caulking vehicle is still the main equipment for road maintenance.
[0003] Traditional road construction caulking devices still have certain shortcomings during use: the current hand-pushed road caulking vehicles are generally equipped with a detachable gun head. When a single worker uses it, the gun head is fixed on one side of the vehicle body. Some roads have many cracks and are widely distributed. At this time, one worker is required to push the vehicle and another worker holds the gun head to fill them along the road. In this case, the worker needs to bend over and hold the gun head to work, which can easily lead to lumbar muscle strain. At the same time, since there is only a single gun head, the dust and other impurities in the cracks on the road surface are not cleaned away, and the asphalt is only spread on the cracks, resulting in poor repair effect. The cracks are likely to continue to expand until they become pits.
[0004] Therefore, it is necessary to provide a new road construction caulking device to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem solved by the utility model is to provide a road construction crack filling device which is not easy to cause lumbar muscle strain when workers hold the gun head to work and is convenient for removing impurities in road cracks before filling.
[0006] In order to solve the above technical problems, the utility model provides a road construction caulking device comprising: a repair component, the repair component comprising an upper bracket, the bottoms of the left and right sides of the upper bracket are slidably connected to the lower bracket, the left and right side walls of the upper bracket are threadedly connected to fastening bolts, the ends of the fastening bolts abut against the lower bracket on the adjacent side, a fan is installed on the surface of the upper bracket on one side, a cantilever is fixedly connected to the surface of the lower bracket located at the lower side of the fan, the end of the cantilever is rotatably connected to a limiting sleeve, the interior of the limiting sleeve is fixedly connected to an air outlet pipe, and the air outlet pipe is connected to the output end of the fan through a pipeline;
[0007] The surface of the lower bracket located at one side of the cantilever is fixedly connected to a sliding sleeve through a connecting plate, a sliding rod is slidably connected inside the sliding sleeve, a ratchet is fixedly connected to the surface of the sliding rod, a pawl is rotatably connected inside the sliding sleeve, a spring rod is hinged between the pawl and the inner wall of the sliding sleeve, the pawl is meshed with the ratchet, a rotating member is fixedly connected to one side wall of the pawl, and the rotating member is located outside the sliding sleeve;

[0009] As a further solution of the utility model, the outside of the gun head is slidably connected to a first mounting piece, the first mounting piece is close to the bottom of the gun head, and the surfaces of the first mounting piece and the second mounting piece are both threadedly connected to a locking bolt, and the end of the locking bolt abuts against the surface of the gun head.
[0010] Through the above technical solution, some roads have many cracks and are widely distributed. At this time, a worker is needed to push a cart and a worker holds a gun to fill them along the road. In this case, the worker needs to bend over and hold the gun to work, which may easily lead to lumbar muscle strain. The device fixes and supports the gun through the upper bracket and the lower bracket. The worker does not need to bend over and hold the gun to work all the time. Instead, he can push the handrail to drive the universal wheel to move when needed. When some occasions require only a single worker to operate, the second fixing part on one side of the upper bracket can be connected to the first fixing part on the base by installing bolts, and the lower bracket on one side can be retracted into the interior of the upper bracket. This can prevent the lower bracket from blocking the worker's line of sight. The structural design is humanized and can prevent the worker's waist from being too tired.
[0011] As a further solution of the utility model, a base is provided at one side of the upper bracket, rotating wheels are installed at the four corners of the bottom of the base, universal wheels are installed at the bottom of the two lower brackets, and an armrest is fixedly connected to the surface of one side wall of the upper bracket.
[0012] Through the above technical solution, one worker slowly moves the base through the wheels, driving various equipment on it to move along the road, while another worker pushes the handrail along the cracks on the road to achieve division of labor and cooperation.
[0013] As a further solution of the utility model, a furnace chamber is installed on one side of the top of the base, a kettle body is fixedly connected to the top of the furnace chamber, an asphalt pump is connected to one side wall of the kettle body through a pipeline, and the output end of the asphalt pump is connected to the gun head through a hose.
[0014] Through the above technical solution, the natural gas in the gas cylinder enters the furnace chamber, and is ignited and burned to heat the asphalt in the kettle. The melted asphalt then enters the gun head through the asphalt pump for repair work.
[0015] As a further solution of the utility model, a gas cylinder and a generator are respectively installed on the upper surface of the base located on one side of the kettle body, and the gas cylinder is connected to the furnace chamber through a pipeline.
[0016] Through the above technical solution, the generator can provide the electricity required for the operation of various electrical appliances in the structure, and the gas cylinder can provide combustible gas for the furnace room.

[0018] Through the above technical solution, when only a single worker is required to operate, the first fixing member and the second fixing member can be fixed by using mounting bolts to fix the repair assembly at one side of the base.
[0019] As a further solution of the utility model, a cleaning brush is fixedly connected to the bottom of the sliding rod, a telescopic rod is fixedly connected to the bottom of the first mounting member, and a scraping member is fixedly connected to the bottom of the telescopic rod.
[0020] Through the above technical solution, when workers hold the gun head to work, due to only a single gun head, the dust and other impurities in the cracks on the road surface are not swept away, and the asphalt is only spread on the cracks, resulting in poor repair effect. The cracks are likely to continue to expand until they become pits. Therefore, the device installs a fan on the upper bracket. When the repair component moves through the universal wheel, the wind of the fan is blown out through the air outlet pipe to sweep the cracks along the road and blow away most of the dust. The cleaning brush behind it can sweep away the remaining dust, stones and other impurities. In this way, when the gun head moves forward, the melted asphalt can be injected into the cracks, so that the repair effect is better.
[0021] Compared with the related art, the road construction caulking device provided by the utility model has the following beneficial effects:
[0022] 1. In the utility model, some roads have many cracks and are widely distributed. At this time, a worker is required to push a cart and a worker holds a gun head to fill them along the road. In this case, the worker needs to bend over and hold the gun head to work, which is easy to cause lumbar muscle strain. The device fixes and supports the gun head through the upper bracket and the lower bracket. The worker does not need to bend over and hold the gun head to work all the time, but pushes the handrail to drive the universal wheel to move when needed. When only a single worker is required to operate in some occasions, the second fixing piece on one side of the upper bracket can be connected with the first fixing piece on the base by using the mounting bolt, and the lower bracket on one side can be retracted into the interior of the upper bracket. This can prevent the lower bracket from blocking the worker's sight. The structural design is humanized and can prevent the worker's waist from being too tired.
[0023] 2. In the utility model, when workers hold the gun head to work, since there is only a single gun head, the dust and other impurities in the cracks on the road surface are not swept away, and the asphalt is only spread on the cracks, resulting in poor repair effect. The cracks are likely to continue to expand until they become pits. Therefore, the device installs a fan on the upper bracket. When the repair component moves through the universal wheel, the wind of the fan is blown out through the air outlet pipe to sweep the cracks along the road and blow away most of the dust. The cleaning brush behind it can sweep away the remaining dust, stones and other impurities. In this way, when the gun head moves forward, the melted asphalt can be injected into the cracks, so that the repair effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 1-4As shown, the outside of the gun head is slidably connected with a first mounting member 13, which is close to the bottom of the gun head. The surfaces of the first mounting member 13 and the second mounting member 16 are both threadedly connected with a locking bolt 17, and the end of the locking bolt 17 abuts against the surface of the gun head.
[0036] Some roads have many cracks and they are widely distributed. At this time, a worker is needed to push a cart and a worker holds a gun to fill them along the road. In this case, the worker needs to bend over and hold the gun to work, which can easily lead to lumbar muscle strain. The device fixes and supports the gun through the upper bracket 10 and the lower bracket 11. The worker does not need to bend over and hold the gun to work all the time. Instead, he can push the handrail to drive the universal wheel 12 to move when necessary. When some occasions require only a single worker to operate, the second fixing part 15 on one side of the upper bracket 10 can be connected to the first fixing part 7 on the base 1 by installing bolts, and the lower bracket 11 on one side can be retracted into the interior of the upper bracket 10. This can prevent the lower bracket 11 from blocking the worker's line of sight. The structural design is humanized and can prevent the worker's waist from being too tired.
[0037] like Figure 1-4 As shown, a base 1 is provided at one side of the upper bracket 10 , rotating wheels are installed at the four corners of the bottom of the base 1 , universal wheels 12 are installed at the bottom of the two lower brackets 11 , and an armrest is fixedly connected to the surface of one side wall of the upper bracket 10 .
[0038] One worker slowly moves the base 1 through the rotating wheels, driving various equipment on it to move forward along the road, while another worker pushes the handrail to move along the cracks on the road, realizing division of labor and cooperation.
[0039] like Figure 1-4 As shown, a furnace chamber 4 is installed at one side of the top of the base 1, a kettle body 5 is fixedly connected to the top of the furnace chamber 4, a side wall of the kettle body 5 is connected to an asphalt pump 6 through a pipeline, and the output end of the asphalt pump 6 is connected to the gun head through a hose 8.
[0040] The natural gas in the gas cylinder 3 enters the furnace chamber 4, and is ignited and burned to heat the asphalt in the kettle body 5. The melted asphalt then enters the gun head through the asphalt pump 6 for repair work.
[0041] like Figure 1-4 As shown, a gas cylinder 3 and a generator 2 are respectively mounted on the upper surface of a base 1 located on one side of a kettle body 5, and the gas cylinder 3 is connected to a furnace chamber 4 through a pipeline.
[0042] The generator 2 can provide the electricity required for the operation of various electrical appliances in the structure, and the gas cylinder 3 can provide combustible gas for the furnace chamber 4.
[0043] like Figure 1-4As shown, a first fixing member 7 is fixedly connected to one side of the top of the base 1, a second fixing member 15 is fixedly connected to one side wall of the upper bracket 10, mounting bolts are inserted into the surface of the first fixing member 7, and threaded holes corresponding to the mounting bolts are opened on the surface of the second fixing member 15.
[0044] When only one worker is required to perform the operation, the first fixing member 7 and the second fixing member 15 can be fixed by mounting bolts to fix the repair assembly 9 at one side of the base 1 .
[0045] like Figure 1-4 As shown, the cleaning brush 20 is fixedly connected to the bottom of the sliding rod 24 , the telescopic rod 14 is fixedly connected to the bottom of the first mounting member 13 , and the scraping member 25 is fixedly connected to the bottom of the telescopic rod 14 .
[0046] When the worker holds the gun head while working, since there is only a single gun head, the dust and other impurities in the cracks on the road surface are not swept away, and the asphalt is only spread on the cracks, resulting in poor repair effect. The cracks are likely to continue to expand until they become pits. Therefore, the device installs a fan 18 on the upper bracket 10. When the repair component 9 moves through the universal wheel 12, the wind of the fan 18 is blown out through the air outlet pipe 21 to sweep the cracks along the road and blow away most of the dust. The cleaning brush 20 behind it can sweep away the remaining dust, stones and other impurities. In this way, when the gun head moves forward, the melted asphalt can be injected into the cracks, so that the repair effect is better.
[0047] The working principle of a road construction crack filling device provided by the utility model is as follows:
[0048] Step 1: Some roads have many cracks and they are widely distributed. At this time, a worker is needed to push a cart and a worker holds a gun head to fill them along the road. In this case, the worker needs to bend over and hold the gun head to work, which is easy to cause lumbar muscle strain. The device fixes and supports the gun head through the upper bracket 10 and the lower bracket 11. The worker does not need to bend over and hold the gun head to work all the time, but pushes the handrail to drive the universal wheel 12 to move when needed. When only a single worker is needed in some occasions, the second fixing member 15 on one side of the upper bracket 10 can be connected with the first fixing member 7 on the base 1 by installing bolts, and the lower bracket 11 on one side can be retracted into the upper bracket 10. This can prevent the lower bracket 11 from blocking the worker's line of sight. The structural design is humanized and can prevent the worker's waist from being too tired.
[0049] The second step: when the worker holds the gun head to work, since there is only a single gun head, the dust and other impurities in the cracks on the road surface are not swept away, and the asphalt is only spread on the cracks, resulting in poor repair effect. The cracks are likely to continue to expand until they become pits. Therefore, the device installs a fan 18 on the upper bracket 10. When the repair component 9 moves through the universal wheel 12, the wind of the fan 18 is blown out through the air outlet duct 21 to sweep the cracks along the road and blow away most of the dust. The cleaning brush 20 behind it can sweep away the remaining dust, stones and other impurities. In this way, when the gun head moves forward, the melted asphalt can be injected into the cracks, so that the repair effect is better.
