Description

Technical Field

[0001] The utility model relates to the technical field of pavement joint sealing, in particular to a rapid construction device for asphalt pavement joint sealing strips. Background Art

[0002] At present, my country's highway traffic volume continues to grow, and roads that were built on a large scale in the past are gradually entering the repair period. In order to improve the service life and road performance of the roads under their jurisdiction, highway management and maintenance units have gradually increased their daily maintenance investment. However, highway maintenance operations are affected by traffic flow and safety control. A road maintenance construction only lasts for one day, and also includes matters such as road closures and enclosures, equipment entry and exit. The actual operation time of road construction is tight, so construction efficiency is crucial to maintenance operations. At present, the maintenance measures for cracks in asphalt pavements on highways are mainly to treat cracks with taping tape, that is, to lay taping tape on the surface of cracks in the asphalt pavement through a pavement taping device to prevent the development of cracks and rainwater infiltration, thereby improving its crack resistance and airtightness;

[0003] For example, the prior art application number CN202220999238.X discloses an anti-crack patch sticking device for road cracks, comprising a fixing plate, a fixing handle is welded and fixed to the top side end of the fixing plate, a bidirectional threaded rod is rotatably connected in the fixing plate, a sliding block is threadedly connected on the bidirectional threaded rod, the sliding block is limitedly slidably connected in the fixing plate, a connecting rod is movably connected to the bottom end of the sliding block, a mounting frame is movably connected to the bottom end of the connecting rod, a fixing spring is welded and fixed to the side end surface of the mounting frame, and a positioning rod is welded and fixed to the other end of the fixing spring. The device is provided with a mounting frame and a cutting blade;

[0004] The above scheme is known through actual use. It is mainly through moving the device to lay the sealing tape on the cracks of the road surface and then applying pressure to the sealing tape through a pressure wheel. However, it is found during use that the pressure wheel in the above scheme is in hard contact with the ground and the distance cannot be changed, which can easily cause inappropriate pressure of the pressure wheel on the sealing tape and cause damage to the sealing tape. At the same time, the pressure wheel is not easy to adapt to different road surfaces. For this reason, we have improved the above-mentioned existing technology according to actual usage.

[0023] like Figures 1 to 5 As shown, an embodiment of the present invention provides a rapid construction device for asphalt pavement joint tape, including a base 1, a handle 2 is provided on the upper surface of the base 1, a joint tape installation roller 4 is provided at the upper end of the base 1, and a pressure wheel component 5 is provided on the left side of the joint tape installation roller 4; the pressure wheel component 5 includes a pressure wheel 52 and a screw 54, the pressure wheel 52 is elastically arranged on the left side of the joint tape installation roller 4, the upper end of the pressure wheel 52 is threadedly provided with a screw 54 for controlling the distance between the pressure wheel 52 and the road surface, and the outer surface of the pressure wheel 52 is made of rubber, which has a shock-absorbing effect on the joint tape and better protects the joint tape.

[0024] The lower surface of the base 1 is provided with a push wheel 3 and a steering wheel 13, and the base 1 is provided with a No. 1 through slot 9 and a No. 2 through slot 10. The upper end of the base 1 is provided with a roller 4 for installing the seam tape by rotation through a mounting frame, and an infrared speed sensor 12 is provided on one side of the mounting frame, and an IC chip is also provided for analyzing the speed of the roller 4 for installing the seam tape. The upper end of the base 1 is also provided with an electric winding roller 6 by a mounting frame, which can cooperate with the infrared speed sensor 12 and the IC chip. The lower end of the base 1 is provided with a No. 1 transition roller 7 and a No. 2 transition roller 8 for threading the seam by rotation through a mounting frame, and the outer surfaces of the No. 1 transition roller 7 and the No. 2 transition roller 8 are coated with an anti-sticking layer to prevent adhesion with the seam tape, and the No. 1 transition roller 7 and the No. 2 transition roller 8 are pressed against the seam tape to guide the seam tape.

[0025] A slide plate 57 is slidably installed in the second through slot 10, a connecting plate 53 is integrally arranged between the two slide plates 57, a column 51 passes through the connecting plate 53, and a pressure wheel 52 is rotatably arranged between the two columns 51 through a bearing. A spring 55 is sleeved on the outer periphery of the column 51, a top cover 56 is fixed to the upper end of the column 51 by bolts, the lower surface of the top cover 56 is fixed to the spring 55, and the lower end of the spring 55 is fixed to the upper surface of the connecting plate 53, and the spring 55 is used to increase the elasticity between the pressure wheel 52 and the ground. A horizontal plate 11 is integrally arranged between the inner walls of the second through slot 10, a screw 54 is rotatably arranged in the horizontal plate 11, and the lower end of the screw 54 is threaded with the connecting plate 53 to drive the connecting plate 53 to move.

[0026] Working principle: Push the handle 2 to move the device forward, and the front steering wheel 13 ensures that the driving track is along the crack direction of the road surface where the seam tape is required to be laid. Before construction, fix the bundled seam tape on the roller 4, then tear off the anti-adhesive film 14 and wind it on the electric winding roller 6, then pull the seam tape through the transition roller No. 1 7 and the transition roller No. 2 8, so that the sticky surface of the seam tape is downward in contact with the cracks on the ground, and the seam tape is laid downward as the device moves forward during construction;

[0027] After the seam tape is laid, the pressing wheel 52 in the pressing wheel member 5 will press the seam tape through the laid seam tape. The elastically arranged pressing wheel 52 can contact the ground in real time and make the seam tape contact the ground cracks more tightly, which is not easy to generate bubbles, thereby improving the laying effect of the seam tape.

[0028] Before use, the screw rod 54 can be rotated clockwise to move the connecting plate 53 downward to drive the pressing wheel 52 downward, and the distance between the pressing wheel 52 and the ground gradually decreases. On the contrary, the screw rod 54 can be rotated counterclockwise to move the pressing wheel 52 upward to increase the distance between the pressing wheel 52 and the ground. The movement of the pressing wheel 52 can be flexibly controlled by rotating the screw rod 54, so as to flexibly control the initial contact force between the pressing wheel 52 and the seam tape, so that the pressing wheel 52 can reasonably apply pressure to the seam tape, avoiding damage to the seam tape due to excessive pressure.

[0029] After the anti-sticking film 14 is wound on the electric winding roller 6, the infrared speed sensor 12 can detect the speed of the device moving to rotate the seam tape installation roller 4, and can reasonably match the speed of the electric winding roller 6 to wind up the anti-sticking film 14, bringing convenience to users.
