Asphalt pavement maintenance device

[0004] The invention provides an asphalt pavement maintenance device, which aims to solve the problem of maintenance and maintenance of the cracks on the road surface by the user through the joint filling machine

The asphalt hot melt tank and the asphalt spray gun are connected by a conveying pipe. Since the conveying pipe is long, the user needs to manually lift the conveyin...

As shown in Figure 5: by setting the cooperative use of limit plate 15, limit groove 18 and support bar 13, can make press limit plate 15 enter in groove 14, limit plate 15 drives support plate 16 Move, the support plate 16 drives the spring 17 to deform under force, install the support rod 13 between the two moving rods 11, loosen the limit plate 15, and the spring 17 is forced and deformed to drive the limit plate 15 into the limit groove 18 , reaching the effect of positioning and supporting the moving rod 11, preventing it from moving up and down.

As shown in Figure 6: by setting the cooperating use of moving rod 11 and moving groove 12, it has played to increase the support height to conveying pipe body 3, and the effect of convenient adjustment, can adjust asphalt conveying pipe according to user's demand The height of the body 3 is adjusted. A support rod 13 is movably connected between the opposite sides of the two moving rods 11, and the left and right sides of the support rod 13 are provided with a groove 14, and the inner chamber of the groove 14 is movably connected with a limiting plate 15, and the two limiters The opposite side of the bit plate 15 is fixedly connected with a support plate 16, and the opposite side of the two support plates 16 is fixedly connected with a spring 17, and the side of the spring 17 near the inner wall of the groove 14 is fixedly connected with the inner wall of the groove 14, and moves A side of the rod 11 close to the support rod 13 is provided with a plurality of limiting slots 18 for use with the limiting plate 15 .

By arranging the cooperating use of the first clamping plate 5 and the second clamping plate 7, one section of the conveying pipe body 3 is clamped and positioned, preventing the first clamping plate 5 and the second clamping plate 7 from sliding left and right, by setting The rolling mechanism 10 can increase the supporting strength of the first splint 5 and the second splint 7, and reduce the friction between the bottom and the ground when moving, so as to facilitate pulling. height and the height adjustment of the first splint 5 and the second splint 7 after using the angle of the asphalt spray gun body 4, by setting the supporting rod 13 and the limit plate 15 in cooperation, it can play a role in the adjustment between the two moving rods 11 The positioning effect prevents up and down movement, which solves the problem that the user can maintain and maintain the cracks on the road surface through the joint filling machine. The asphalt hot melting tank and the asphalt spray gun are connected through the conveying pipe. Due to the long conveying pipe, the user needs to manually place the Lifting the conveying pipe keeps the conveying pipe away from the ground, which is not conducive to the long-term work of the user and reduces work efficiency, and it is easy to cause damage to the user's body if it is lifted for a long time. During the operation, the operation difficulty of the user will be increased, whic...
