Description

Technical Field

[0001] The utility model belongs to the technical field related to highway construction, and particularly relates to a rapid repair device for highway cracks. Background Art

[0002] There are many reasons for the occurrence of cracks on highways, including: (1) Problems with the foundation of highways. During the construction of highways, some highways are located in low-lying hills and river valleys. Their foundations are soaked and eroded by groundwater, which will damage the strength, rigidity and stability of the highways, and then affect the highway pavement, causing cracks in the highway pavement due to uneven force. (2) Reasons for roadbed and pavement construction. During the construction of roadbed and pavement, it is very easy to cause some cracks. (3) After the pavement seeps water, the change in water content in the base layer will lead to further development of cracks. In order to make better use of the highway, after the cracks are found, they need to be repaired as much as possible to meet the normal use of vehicles; but as for the current highway crack repair devices, there are still the following disadvantages in actual use:

[0003] Conventional roads are built with concrete on the bottom layer and asphalt on the bottom layer. Cracks usually occur in the asphalt layer, so asphalt is usually used for repair. However, since cracks are mostly irregular, it is difficult to accurately control the amount of asphalt filled during repair, and overflow often occurs. After repair, the cracks will also be formed in the shape of the cracks, resulting in an unsightly ground surface. Therefore, it is necessary to form the cracks into regular shapes and accurately control the filling amount.

[0004] Secondly, in order to meet the above-mentioned regular shape of the crack, it is necessary to cut it. Secondly, the crack usually contains some debris, which needs to be cleaned before repairing. However, the current road crack repair method cannot handle both at the same time.

[0005] Finally, conventional crack repair devices place asphalt in the cracks and then use rollers to flatten them. This method requires the rollers to be very heavy and is not easy to carry. Secondly, one roller press may not be able to meet the flattening requirements, which greatly increases the workload. Utility Model Content

[0006] The purpose of the utility model is to provide a rapid repair device for road cracks. By arranging a frame, a cutting wheel and a cutting shaft rod, the problem that the crack shape is irregular and the asphalt filling amount cannot be accurately controlled is solved; by arranging a water tank, a main pipe and an arc-shaped nozzle, the problem that the debris inside the crack cannot be cleaned together when the crack is cut is solved; by arranging a hydraulic cylinder and a pressure plate, the problem that the conventional roller pressing structure is too heavy and difficult to carry, and one roller pressing cannot meet the flattening requirements is solved.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a rapid repair device for road cracks, comprising a base, a hydraulic cylinder, an asphalt storage tank and a frame. The upper end of the base is fixed with a hydraulic cylinder, and the telescopic end of the hydraulic cylinder penetrates downwardly through the base and is fixed with a pressure plate.

[0009] An asphalt storage tank is also fixed on the base on one side of the hydraulic cylinder, a through slot is provided in the base on the side of the asphalt storage tank away from the hydraulic cylinder, and an inverted U-shaped frame is movably connected up and down in the through slot;

[0010] A water tank and a motor are fixed to the upper end of the frame, a cutting shaft is rotatably connected between the two end walls inside the frame, and two cutting wheels are sleeved on the cutting shaft;

[0011] A main pipe is fixed between the two inner end walls of the frame, and two symmetrical arc-shaped nozzles are fixed through the lower part of the outer periphery of the main pipe, and the nozzles of the arc-shaped nozzles face the surface of the cutting wheel.

[0012] Furthermore, the ends on both side surfaces of the base are rotatably connected to running wheels, and the discharge port at the bottom of the asphalt storage tank also extends downward through the base, and the lowest point of the running wheel is lower than the position of the pressure plate in the retracted state and also lower than the lowest position of the discharge port of the asphalt storage tank.

[0013] Furthermore, symmetrically distributed limiting rods are fixed on both end walls in the through slot, and limiting grooves corresponding to the positions of the limiting rods are provided on both outer end walls of the frame, and the limiting rods are inserted into the limiting grooves.

[0014] Furthermore, the upper ends of the bases on both sides of the frame are rotatably connected with screws, and the upper ends of the screws are fixed with hand wheels. Adjustment blocks are fixed on both sides of the upper part of the frame, and the screws are inserted into the adjustment blocks and threadedly connected with the adjustment blocks.

[0015] Furthermore, the output shaft of the motor faces the outer end of the frame and is fixed with a driving gear, and the end of the cutting shaft rod close to the motor passes through the end of the frame and extends out and is fixed with a driven gear, and the driving gear is meshed and connected with the driven gear.

[0016] Furthermore, a thread is arranged on the outer periphery of the cutting shaft located in the frame, and the cutting wheel is located outside the threaded section of the cutting shaft, and locking nuts are threadedly connected on the cutting shafts on both sides of the cutting wheel.

[0017] Furthermore, a water pipe with a valve is connected through the outer periphery of the main pipe, and one end of the water pipe away from the main pipe is fixedly connected to the lower part of the water tank, and the main pipe is located obliquely above the cutting shaft.

[0018] The utility model has the following beneficial effects:

[0019] The utility model solves the problem of irregular crack shapes and inability to accurately control the amount of asphalt filling by setting a frame, a cutting wheel, and a cutting shaft rod; the control frame is lowered, and the cutting shaft rod is rotated in conjunction with the motor drive, so that the cutting wheel rotates, and the periphery of the ground crack is cut to form a regular shape, and the cutting wheel can be adjusted on the cutting shaft rod to be sufficient to meet the needs of cracks of various sizes. After the cracks are cut into regular shapes, the required amount of asphalt can be calculated, and a certain amount of asphalt can be accurately injected to achieve perfect repair.

[0020] The utility model solves the problem that the debris inside the crack cannot be cleaned together when the crack is cut by arranging a water tank, a main pipe and an arc-shaped nozzle. During cutting, a certain amount of clean water is stored in the water tank, transmitted through the main pipe, and sprayed onto the surface of the cutting wheel through the arc-shaped nozzle, so that the surface is cooled during cutting and dust reduction can be achieved. Finally, after the cutting is completed, the rotation of the cutting wheel is stopped and the arc-shaped nozzle can be manually controlled to spray into the crack to clean the debris inside. A high-pressure pump is arranged in the water tank to achieve high-pressure cleaning.

[0021] The utility model solves the problems that the conventional roller pressing structure is too heavy and difficult to carry, and one-time rolling cannot meet the flattening requirements by arranging hydraulic cylinders and pressing plates; the traditional roller pressing structure is improved and the deadweight is greatly reduced. After the cracks are filled with asphalt, the hydraulic cylinder is directly used to drive the pressing plate to descend for pressing and flattening. The gradual hydraulic pressing is far more efficient than roller pressing, and even if the deadweight of the device is insufficient during flattening, the operator can stand on the base to increase the deadweight.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-5 As shown, the utility model is a rapid repair device for road cracks, comprising a base 1, a hydraulic cylinder 2, an asphalt storage tank 3 and a frame 4. The hydraulic cylinder 2 is fixed to the upper end of the base 1, and the telescopic end of the hydraulic cylinder 2 passes through the base 1 downward and is fixed with a pressing plate 201;

[0032] After the asphalt fills the crack, the hydraulic cylinder 2 can be controlled to work, so that the pressing plate 201 can be lowered, so that the pressing plate 201 can press and flatten the asphalt in the crack to maintain a certain flatness. It is lighter than the traditional roller pressing structure, more practical and labor-saving, and suitable for repairing small cracks;

[0033] An asphalt storage tank 3 is also fixed on the base 1 on one side of the hydraulic cylinder 2. A through groove 104 is provided in the base 1 on the side of the asphalt storage tank 3 away from the hydraulic cylinder 2, and an inverted U-shaped frame 4 is movably connected up and down in the through groove 104.

[0034] The asphalt storage tank 3 stores the asphalt required for filling the cracks, which is a conventional structure and will not be described in detail. The frame 4 can be vertically lifted and lowered in the through slot 104;

[0035] A water tank 401 and a motor 402 are fixed to the upper end of the frame 4. A cutting shaft 403 is rotatably connected between the two end walls inside the frame 4, and two cutting wheels 5 are sleeved on the cutting shaft 403.

[0036] The motor 402 provides the driving force required for the cutting shaft 403 to rotate. When the cutting shaft 403 rotates, it can drive the cutting wheel 5 to rotate, thereby cutting around the cracks on the ground.

[0037] A main pipe 404 is fixed between the two inner end walls of the frame 4. Two symmetrical arc-shaped nozzles 4041 are fixed through the lower part of the outer periphery of the main pipe 404, and the nozzles of the arc-shaped nozzles 4041 face the surface of the cutting wheel 5.

[0038] The water used for cleaning and cooling is collected in the main pipe 404 and then sprayed out through two arc-shaped nozzles 4041. The arc-shaped nozzles 4041 are hoses. When sprayed toward the surface of the cutting wheel 5, the cutting wheel 5 can be used to cool it when it is working.

[0039] The ends on both sides of the base 1 are rotatably connected with running wheels 101, and the discharge port at the bottom of the asphalt storage tank 3 also extends downward through the base 1, and the lowest point of the running wheel 101 is lower than the position of the pressure plate 201 in the retracted state and also lower than the lowest position of the discharge port of the asphalt storage tank 3;

[0040] The base 1 can be used for short-distance walking and displacement through the walking wheel 101, mainly moving around the crack, and when the pressure plate 201 and the cutting wheel 5 are not working, the position of the walking wheel 101 is the lowest, and the cutting wheel 5 will be lower than the position of the walking wheel 101 when cutting, and the pressure plate 201 will touch the ground when working.

[0041] The two end walls in the through slot 104 are also fixed with symmetrically distributed limiting rods 103, and the two outer end walls of the frame 4 are provided with limiting grooves 405 corresponding to the positions of the limiting rods 103, and the limiting rods 103 are inserted into the limiting grooves 405;

[0042] By inserting the limiting rod 103 into the limiting groove 405, both ends of the frame 4 can be stably limited to avoid excessive deviation.

[0043] The upper ends of the bases 1 on both sides of the frame 4 are also rotatably connected with screw rods 102, and the upper ends of the screw rods 102 are fixed with hand wheels 1021. Adjustment blocks 406 are fixed on both sides of the upper part of the frame 4, and the screw rods 102 are inserted into the adjustment blocks 406 and are threadedly connected with the adjustment blocks 406.

[0044] The screw rod 102 is rotated by the hand wheel 1021 to lower the adjusting block 406 and the frame 4, so that the cutting wheel 5 located in the frame 4 is lowered to contact the ground for cutting.

[0045] The output shaft of the motor 402 faces the outer end of the frame 4 and is fixed with a driving gear 4021, and the end of the cutting shaft 403 close to the motor 402 passes through the end of the frame 4 and extends out and is fixed with a driven gear 4031, and the driving gear 4021 is meshed and connected with the driven gear 4031;

[0046] When the motor 402 is working, it drives the driving gear 4021 to rotate, thereby engaging the driven gear 4031 to rotate, and then the cutting shaft 403 rotates.

[0047] The outer periphery of the cutting shaft 403 located in the frame 4 is provided with threads, and the cutting wheel 5 is located outside the threaded section of the cutting shaft 403, and the cutting shaft 403 on both sides of the cutting wheel 5 are threadedly connected with locking nuts 4032;

[0048] The distance between the two cutting wheels 5 is adjusted according to the crack, and locking nuts 4032 are provided on both sides of each cutting wheel 5 to lock on the threaded section of the cutting shaft 403 to keep the position of the cutting wheel 5 constant.

[0049] A water pipe 4042 with a valve is also connected to the outer periphery of the main pipe 404, and one end of the water pipe 4042 away from the main pipe 404 is fixed to the lower part of the water tank 401, and the main pipe 404 is located obliquely above the cutting shaft 403;

[0050] A high-pressure pump (omitted in the figure) is arranged in the water tank 401 to output high-pressure water, which is output to the main pipe 404 through the water pipe 4042 and then sprayed to the surface or cracks of the cutting wheel 5 through the arc nozzle 4041.

[0051] The specific working principle of the utility model is as follows: first, the device is moved above the crack to be repaired, and the spacing between the two cutting wheels 5 is adjusted according to the crack. After the adjustment, the cutting wheel 5 is locked on the cutting shaft 403 by using the locking nut 4032. Then, the motor 402 is started to drive the driving gear 4021 to rotate, thereby engaging the driven gear 4031 to rotate, and then the cutting shaft 403 rotates, and then the cutting wheel 5 rotates. At this time, the screw 102 is rotated by the hand wheel 1021 to make the adjustment block 406 and the frame 4 descend, so that the cutting wheel 5 located in the frame 4 descends to contact the ground for cutting;

[0052] At the same time, a high-pressure pump is arranged in the water tank 401 to output high-pressure water, which is output to the main pipe 404 through the water pipe 4042, and then sprayed to the surface of the cutting wheel 5 through the arc nozzle 4041 to cool and reduce dust. After the cutting is completed, the motor 402 and the cutting wheel 5 are stopped, and the arc nozzle 4041 can be held to further clean out the impurities remaining in the crack;

[0053] After the crack cutting is completed, the device is moved forward to align the discharge port at the bottom of the asphalt storage tank 3 with the crack, and the required asphalt is input; the device is moved forward again to align the pressing plate 201 with the crack, and the hydraulic cylinder 2 works to lower the pressing plate 201, so that the pressing plate 201 presses and flattens the asphalt in the crack to maintain a certain flatness, and the repair operation is completed.

[0054] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
