Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, and more specifically to a crack repairing device for damaged roads. Background Art

[0002] With the continuous development of transportation, highway construction is becoming increasingly important. However, during the long-term use of highways, cracks and other damages often occur due to the influence of various factors. In order to ensure the normal use of highways and driving safety, it is necessary to repair the cracks of damaged highways in a timely and effective manner.

[0003] At present, when repairing road cracks, asphalt caulking machines are usually used to inject asphalt to repair road cracks. During the operation, an annular scraper that can accommodate part of the asphalt liquid is usually equipped. The positions of the annular scraper and the nozzle correspond. When in use, the annular scraper moves to scrape the sprayed area flat. Although this method can greatly improve the efficiency of crack repair, since the operation is basically a continuous operation, the asphalt liquid will be continuously discharged, and the asphalt liquid that can be accommodated inside the annular scraper is limited, which will cause the filtered asphalt liquid to accumulate inside the annular scraper.

[0004] On the one hand, the accumulated asphalt liquid overflowing in the annular scraper will cause waste and increase the repair cost. On the other hand, the accumulated asphalt liquid stays in the annular scraper for a long time and may be affected by factors such as external temperature, resulting in changes in the properties of the asphalt, such as a decrease in softening point and viscosity, thereby affecting the effect and durability of crack repair. For this reason, we propose a crack repair device for damaged roads. Utility Model Content

[0026] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0027] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0028] Embodiment 1:

[0029] like Figure 1-Figure 4As shown, a crack repair device for damaged roads includes a tank truck body 1, which contains an asphalt tank, a heating device, an injection device and a control device. The tank truck body 1 is a publicly available technology and is not described in detail here. The tank truck body 1 is connected to a transmission pipe 2 that can discharge the asphalt liquid in the tank truck body 1 to the outside, and an injection conduit 3 is installed at the end of the transmission pipe 2 away from the tank truck body 1. An injection head 5 is installed at the end of the injection conduit 3 away from the transmission pipe 2. A scraper frame 6 is provided at the end of the injection head 5 away from the injection conduit 3, and a movable adjusting member 7 movably connected to the injection head 5 is installed on the scraper frame 6, and the movable adjusting member 7 allows the scraper frame 6 to rotate on the injection head 5.

[0030] In this embodiment, the scraper frame 6 is brought into contact with the ground through a handheld injection conduit 3, and the asphalt liquid inside the tank truck body 1 is transmitted to the injection head 5 and discharged onto the road cracks. At the same time, the scraper frame 6 is moved to the corresponding position of the crack by the user, so that the asphalt sprayed on the crack is scraped flat.

[0031] Furthermore, a hand-held block 4 is fixedly installed on one end of the injection conduit 3 close to the transmission pipe 2, and a spacing groove for increasing friction is provided on the hand-held block 4. The injection conduit 3 is provided with a flow limiting component for controlling the asphalt discharge amount.

[0032] Furthermore, the current limiting component includes a regulating box 8, which is a rectangular box. The regulating box 8 is installed on the injection conduit 3. The interior of the regulating box 8 and the interior of the injection conduit 3 are interconnected. Isolation plates are provided on both sides of the interior of the regulating box 8. The spacing between the two groups of isolation plates is adapted to the inner diameter of the injection conduit 3.

[0033] Furthermore, the current limiting assembly includes a pressure-bearing closing member and a pressure member, and the pressure-bearing closing member is arranged inside the regulating box 8 .

[0034] In this embodiment, the pressure-bearing closing member is pressed by pushing the pressure member so that the pressure-bearing closing member is gradually closed inside the regulating box 8 .

[0035] Furthermore, the pressure member includes an adjusting ring 9 and a pushing rod 10. The adjusting ring 9 is in a circular ring shape and is arranged between the hand-held block 4 and the adjusting box 8. The adjusting ring 9 is slidably installed on the transmission tube 2. The pushing rod 10 is divided into two groups. The two groups of pushing rods 10 are arranged between the adjusting box 8 and the adjusting ring 9. One end of the pushing rod 10 is fixedly installed on the adjusting ring 9, and the other end of the pushing rod 10 slides through the corresponding position wall of the adjusting box 8 and extends to the inside of the adjusting box 8. The pushing rod 10 is located on the side of the two groups of isolation plates inside the adjusting box 8 away from each other, and the end of the pushing rod 10 away from the adjusting ring 9 is in contact with the pressurized closing member.

[0036] In this embodiment, by pushing the external adjustment ring 9, the push rod 10 can be driven to push the pressurized closure member, which can effectively make the pressurized closure member gradually close inside the adjustment box 8, thereby limiting the flow of asphalt liquid transmitted inside the injection conduit 3.

[0037] Furthermore, the pressurized closing component includes a blocking plate 11, a pressure plate 12, a fixed shaft 13, a movable sleeve 14, a movable slot 15 and a receiving groove 16. The movable slot 15 is provided on the internal isolation plate of the adjusting box 8. The fixed shaft 13 is arranged inside the movable slot 15. Both ends of the fixed shaft 13 are mounted on the wall surface at corresponding positions on the inner ends of the movable slot 15. The movable sleeve 14 is movably mounted on the fixed shaft 13. The blocking plate 11 is fixedly mounted on the movable sleeve 14 in an area between the two groups of isolation plates. The length of the blocking plate 11 is not greater than half of the distance between the two groups of isolation plates. The pressure plate 12 is fixedly mounted on the movable sleeve 14 at an angle upward on a side away from the blocking plate 11. The top end of the pressure plate 12 and the bottom end of the pushing rod 10 fit each other. A receiving groove 16 capable of accommodating the blocking plate 11 is provided on the internal isolation plate of the adjusting box 8 corresponding to the blocking plate 11.

[0038] In this embodiment, the pressure plate 12 is squeezed by the push rod 10, so that the pressure plate 12 transmits the force through the movable sleeve 14. Under the action of the pressure plate 12 gradually descending, the baffle plate 11 is gradually lifted, so that the gap between the two groups of baffle plates 11 gradually becomes smaller, thereby controlling the asphalt liquid discharge.

[0039] Furthermore, the length of the pressure plate 12 is shorter than the length of the blocking plate 11 .

[0040] In this embodiment, the pressure plate 12 is shorter than the blocking plate 11, so that it is more difficult for the push rod 10 to lift the blocking plate 11 through the pressure plate 12, thereby effectively avoiding the situation where the two sets of blocking plates 11 are gradually closed due to non-user active manipulation during the operation.

[0041] Embodiment 2:

[0042] Based on the first embodiment, Figure 5-Figure 8 As shown, a crack repair device for damaged roads includes an adjusting ring 9, a rotary adjustment groove 23 is opened on the adjusting ring 9 corresponding to the position of the pushing rod 10, a rotary slider 24 that can slide inside the rotary adjustment groove 23 is arranged inside the rotary adjustment groove 23, and the rotary slider 24 and the pushing rod 10 are connected to each other.

[0043] In this embodiment, the adjusting ring 9 can be rotated by the sliding block 24 without causing the push rod 10 to deviate.

[0044] Furthermore, an auxiliary groove 17 is provided on the injection catheter 3 at a position corresponding to the adjustment ring 9. The auxiliary groove 17 is an annular groove. Several groups of locking rings 18 that can rotate on the auxiliary groove 17 are arranged at intervals on the auxiliary groove 17. A sliding groove 20 is provided on the inner side of the adjustment ring 9. Both ends of the sliding groove 20 pass through the inner ends of the adjustment ring 9. A locking block 19 is fixedly installed on the locking ring 18 at a position corresponding to the sliding groove 20. The size of the locking block 19 is adapted to the inner size of the sliding groove 20.

[0045] In this embodiment, the adjusting ring 9 can slide on the locking blocks 19 on the multiple sets of locking rings 18 through the sliding groove 20 .

[0046] Furthermore, a screwing groove 21 is opened on the inner side of the locking ring 18 corresponding to the position of the locking block 19, and a limit block 22 is arranged on the inner side of the screwing groove 21. The width of the limit block 22 is half of the width of the inner side of the screwing groove 21, and the limit block 22 is fixedly installed on the injection catheter 3.

[0047] In this embodiment, the locking ring 18 can rotate slightly inside the auxiliary groove 17 through the screw groove 21 by means of the fixed limiting block 22 .

[0048] In this embodiment, the auxiliary groove 17 that can rotate slightly is used to allow the adjustment ring 9 to rotate after being pushed to a certain position, thereby effectively driving the locking ring 18 at the corresponding position to rotate inside the auxiliary groove 17, so that the locking ring 18 in the area of ​​the adjustment ring 9 is offset. At this time, the locking blocks 19 on the locking rings 18 on both sides of the adjustment ring 9 are misaligned with the positions of the sliding grooves 20 on the adjustment ring 9, thereby limiting the adjustment ring 9, so that the spacing between the two groups of baffles 11 inside the adjustment box 8 can be fixed, so that a quantitative asphalt liquid can be discharged over a longer period of time.

[0049] The working principle and use process of the utility model are as follows: when in use, the user holds the hand-held block 4 and the adjustment ring 9 on the injection conduit 3 to guide the injection conduit 3, and discharges the asphalt liquid transmitted through the injection conduit 3 to the road cracks in the designated area. At the same time, the user moves, thereby driving the scraper frame 6 to scrape the asphalt liquid on the road cracks, thereby completing the asphalt filling and repair operation of the road cracks.

[0050] By pushing the adjusting ring 9, the two groups of baffle plates 11 inside the adjusting box 8 are lifted up by being squeezed by the pushing rod 10 through the pressure plate 12, so that the interval between the two groups of baffle plates 11 is gradually reduced, limiting the amount of asphalt liquid discharged outward, thereby effectively reducing the waste of asphalt liquid and the accumulation pollution caused by excessive asphalt liquid during the repair operation.

[0051] By making the pressure plate 12 shorter than the baffle plate 11, it is more laborious to squeeze the pressure plate 12 to drive the baffle plate 11 to lift, which can effectively reduce the lifting and closing operation of the two groups of baffle plates 11 inside the regulating box 8 due to accidental triggering, thereby effectively avoiding the occurrence of accidental flow restriction of the asphalt liquid.

[0052] By pushing the adjusting ring 9 to move to a certain position and then rotating the adjusting ring 9, the locking ring 18 in the area of ​​the adjusting ring 9 is offset. At this time, the locking blocks 19 on the locking rings 18 on both sides of the adjusting ring 9 are misaligned with the positions of the sliding grooves 20 on the adjusting ring 9, thereby limiting the adjusting ring 9, so that the interval between the two groups of baffles 11 inside the adjusting box 8 is locked, thereby effectively controlling the quantitative and continuous discharge of the asphalt liquid.

[0053] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
