Description

Technical Field

[0001] The invention relates to the field of bridge maintenance, and more particularly to a crack filling and repairing device for road bridge construction. Background Art

[0002] Roads and bridges are generally composed of several parts, including pavement, roadbed, bridges, tunnel projects and traffic projects. Among them, the pavement of bridges is particularly susceptible to damage, especially at the connection between roads and bridges. Cracks are very likely to occur due to various reasons. The cracks will extend to the pavement or bridge. The generation of cracks not only reduces the service life of roads and bridges, but also affects bridges and roadbeds due to the infiltration of rainwater.

[0003] When repairing cracks on the surface of roads and bridges, some workers will use bagged cold-filled seam glue. Although the packaging cost of bagged cold-filled seam glue is reduced, the workers need to use both hands to continuously squeeze the packaging bag of bagged cold-filled seam glue during use, forcing the cold-filled seam glue inside the packaging to be squeezed out, thereby increasing the workload of the workers and simultaneously affecting the glue output speed of the cold-filled seam glue, thereby reducing the efficiency of road and bridge crack repair.

[0004] In response to this technical problem, a Chinese patent with authorization announcement number CN114481785A discloses a crack filling device for road and bridge construction. When the invention uses bagged cold-filled seam glue to repair cracks in roads and bridges, workers do not need to continuously squeeze the packaging bags of cold-filled seam glue, thereby effectively saving the workers' physical strength and reducing their workload, while also improving maintenance efficiency. However, when the device squeezes the bagged cold-filled seam glue, as the bag is folded, a lot of glue is likely to remain inside the bag, resulting in a waste of construction materials. In addition, like most existing cart-type crack filling devices, this device uses the original wheels of the vehicle body to sense the horizontality of the road surface. This method is fine for flat roads or bridge decks, but the cracks generated at the ground connections of some roads and most bridges are uneven. When the ground flatness at the glue outlet is significantly different from the flatness of the contact between the frame and the wheel, it is easy to cause glue injection errors or damage to the glue injection components. In addition, when the device fills a winding crack, it is necessary to frequently adjust the direction of the vehicle body, or to manually fill the crack, which brings trouble to the filling process.

[0005] Therefore, a crack filling and repairing device for road and bridge construction is proposed. Summary of the invention

[0024] like Figure 2 , 3 As shown, the auxiliary mechanism 6 includes a slide rod seat 61 fixedly connected to the outer surface of the other side of the inclined plate 4, the rear surface of the slide rod seat 61 is fixedly connected to a limiting slide rod 62, the outer surface of the limiting slide rod 62 is slidably connected to a support block 63, and the support block 63 is rotatably connected to the outer surface of the other side of the pressure plate 7.

[0025] like Figure 2 , 4 As shown in Figures 5 and 6, the rotating locking mechanism 8 includes a buckle groove 81 formed on the upper surface of the inclined plate 4, and a limiting groove 82 is formed on the upper surface of the inclined plate 4 near the buckle groove 81. The interior of the limiting groove 82 extends to the interior of the buckle groove 81 and is slidably connected with a latch 83. The latch 83 passes through the entire buckle groove 81 and abuts against the inner surface of one side of the buckle groove 81. A buckle seat 84 is fixedly connected to the front surface of the pressure plate 7, and the latch 83 can pass through the inner surface of the buckle seat 84.

[0026] like Figure 1 , 2 As shown in , 7 and 10, the glue injection assembly 9 includes a conical head 91 fixedly connected to the lower side of the rear surface of the inclined plate 4, the outer surface of the conical head 91 extends to the inner surface and is threadedly connected with a fixing bolt 92, the lower end of the conical head 91 is fixedly connected with a hose 93, and the lower end of the hose 93 is fixedly connected with a glue injection head 94, and an adaptive mechanism 95 is arranged on the outside of the glue injection head 94, the rear side of the inner surface displacement fixing seat 2 of the vehicle body 1 is fixedly connected with the limiting frame 11, and the hose 93 passes through the limiting hole of the limiting frame 11.

[0027] By adopting the above technical solution, when it is necessary to fill and repair special cracks on the bridge, the transmission motor 52 can be started first to drive the one-way screw rod 53 to rotate, so that the first nut seat 54 is away from the motor seat 51, and then the latch 83 inside the limit groove 82 is moved to make the latch 83 break away from the restriction of the buckle seat 84, and the pressure plate 7 is rotated to open, and the bagged cold-filled seam glue is placed upside down on the inclined plate 4 to fit the inclined plate 4, and the injection port of the bagged cold-filled seam glue is placed inside the conical head 91, so that the injection port is pressed down and close to the inner surface of the conical head 91, and the fixing bolt 92 is tightened to fix the injection port, and the pressure plate 7 is rotated to be close to the inclined plate 4 so that the latch 83 is free from the restriction of the buckle seat 84. 83 is inserted into the interior of the buckle seat 84 again for locking. By controlling the reverse rotation of the transmission motor 52, the lower end of the pressing plate 7 can be driven to gradually approach the lower end of the inclined plate 4 to complete the gradual extrusion action. During the extrusion process, the glue inside the bag body can flow out from the glue injection head 94 through the hose 93. The limit frame 11 can prevent the hose 93 from dragging on the ground. When the pressing plate 7 is opened, the support block 63 is at the outer cylindrical surface of the limit slide bar 62. The limit slide bar 62 and the one-way screw rod 53 can be placed on the limit frame 11, which can play an auxiliary supporting role. During the extrusion process, the support block 63 can also slide on the outer cylindrical surface of the limit slide bar 62 to improve stability.

[0028] like Figure 1 , 8 As shown in Figure 9, the adaptive mechanism 95 includes a slide rail 951 fixedly connected to the inner surface of the vehicle body 1 and located at the rear side of the limit frame 11, a slide 952 is arranged outside the slide rail 951, and the outer surface of the slide 952 is rotatably connected to four rollers 953, and the upper and lower surfaces of the slide 952 are threadedly connected to a lifting screw 954, and the lifting screw 954 is fixedly locked by a bolt knob, and the lower end of the lifting screw 954 is fixedly connected to a telescopic elastic rod 955, and the lower end of the telescopic elastic rod 955 is fixedly connected to a base plate 956, and the lower surface of the base plate 956 is fixedly connected to The rotating shaft 957 is provided with a glue injection head 94 on the outside of the rotating shaft 957, a guide assembly 958 is provided between the glue injection head 94 and the rotating shaft 957, the lower end of the rotating shaft 957 is rotatably connected with a universal wheel 959, and the universal wheel 959 is a double-wheel design. The double-wheel design of the universal wheel 959 can prevent a single wheel from getting stuck in the gap and causing damage to the guide assembly 958. The slide rail 951 is fixedly connected to the inside of the vehicle body 1 by bolts, which is convenient for installation and disassembly. The outside of the telescopic elastic rod 955 is a telescopic sheath, and a spring is provided inside. A telescopic rod for support is provided inside the spring.

[0029] like Fig. 9 , 10As shown in Figures 11, the guide assembly 958 includes a ring 9581 arranged on the outer cylindrical surface of the rotating shaft 957, the outer cylindrical surface of the ring 9581 is fixedly connected to a connecting rod 9582, one end of the connecting rod 9582 is fixedly connected to a fixing rod 9583, the lower section of the outer cylindrical surface of the fixing rod 9583 is sleeved with a roller 9584, the middle section of the outer cylindrical surface of the fixing rod 9583 is fixedly connected to a limiting disk 9585, the outer cylindrical surface of the fixing rod 9583 is located on the upper surface of the limiting disk 9585 and is sleeved with a follower rod 9586, and the injection head 94 is fixedly connected to the inner surface of the follower rod 9586 by a bolt knob.

[0030] By adopting the above technical solution, before injecting glue, the fixing rod 9583 of the vehicle body 1 can be aligned with the crack to be filled, and the lifting screw 954 can be rotated to allow the fixing rod 9583 and the lower end of the glue injection head 94 to penetrate into the crack. At this time, the universal wheel 959 is close to the road surface beside the crack opening, and the telescopic elastic rod 955 is slightly pressed. During the glue injection process, it is only necessary to let the crack pass between the front wheels of the vehicle body 1 to achieve adaptive glue injection. During the adaptive glue injection process, the vehicle body 1 is slowly pushed forward, and the roller 9584 rolls on the inner surface of the crack for testing. During the testing process, if the crack is When the direction changes, the roller 953 can slide adaptively on the slide rail 951, and the glue injection head 94 follows the rear of the roller 9584 and moves forward in the crack, achieving the purpose of following by a rotating connection. During the movement of the vehicle body 1, if the flatness of the road surface next to the crack changes, the universal wheel 959 rolling against the road surface can drive the telescopic elastic rod 955 to adaptively extend and retract, so that the roller 9584 and the glue injection head 94 can follow the extension and retraction, thereby avoiding a large difference in the flatness of the road surface originally contacted by the wheels of the vehicle body 1 and the road surface at the crack, resulting in glue injection errors or damage to the guide component 958.

[0031] like Fig.10 , 11 As shown, a fastening bolt 12 is provided on the surface of the collar 9581, and the position where the collar 9581 and the fastening bolt 12 penetrate is designed to be broken, so that the collar 9581 can undergo elastic deformation.

[0032] like Fig.11 As shown, a screw hole 13 is formed at the lower end of the fixing rod 9583 , and a fixing screw 14 is threadedly connected to the inner portion of the screw hole 13 , and the diameter of the lower end of the fixing screw 14 is larger than the diameter of the roller 9584 .

[0033] By adopting the above technical solution, when the roller 9584 is severely worn, the fixing screw 14 can be unscrewed to replace the roller 9584. When the guide assembly 958 is accidentally damaged, the fastening bolt 12 can be unscrewed to install a new guide assembly 958 on the rotating shaft 957. During installation and disassembly, the ring 9581 can be deformed and opened.

[0034] like Figure 2 , 3As shown in Figures 6 and 7, the supporting mechanism 10 includes a bidirectional screw rod 101 rotatably connected to the inside of the inclined plate 4 and extending to the outer surface. The outer cylindrical surface of the bidirectional screw rod 101 is threadedly connected to two second nut seats 102. The outer surface of the second nut seat 102 is fixedly connected to a supporting rod 103. Two alignment holes 104 are formed through the surface of the pressure plate 7. One end of the bidirectional screw rod 101 is fixedly connected to a hand wheel.

[0035] By adopting the above technical solution, when the bagged cold-filled seam glue is placed on the inclined plate 4, the bidirectional screw 101 can be rotated by a hand wheel to control the two second nut seats 102 to move closer or further away, thereby driving the supporting rod 103 to move closer or further away. The spacing of the supporting rods 103 can be adjusted according to the width of the bagged cold-filled seam glue bag, so that the supporting rods 103 can better support the bag body and prevent the bag body from tilting and falling, affecting the extrusion and injection operation. The design of the alignment hole 104 avoids interference between the supporting rod 103 and the pressing plate 7 during the extrusion process.

[0036] Instructions for use: When special cracks on the bridge need to be filled and repaired, the pressing plate 7 can be opened by rotating the locking mechanism 8, and the bagged cold-filled seam glue can be inverted and placed on the inclined plate 4 to fit the inclined plate 4. The bag body can be supported by the supporting mechanism 10, so that the injection port of the bagged cold-filled seam glue is pressed down and pressed against the inner surface of the conical head 91, and the fixing bolt 92 is tightened to fix the injection port. Then, the lifting screw 954 is rotated to press the telescopic elastic rod 955, the universal wheel 959 fits the ground, the roller 9584 and the injection head 94 are inserted into the crack, and the transmission motor 52 can be started to squeeze and fill. When the vehicle body 1 is moving, the crack only needs to pass between the front wheels of the vehicle body 1 to achieve the adaptive filling effect.

[0037] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
