Description

Technical field:

[0001] The utility model belongs to the field of road and bridge repair, and in particular relates to a road surface seam tape construction device. Background technology:

[0002] During the use of highways, the road surface often develops cracks and damage due to the impact of moving vehicles, impact, wear and tear, and weather changes. These cracks and damages are collectively referred to as road damage.

[0003] Crack grouting or taping are commonly used methods for repairing road pavement cracks. Cracks larger than 2 cm are repaired using slotting and grouting, while minor cracks less than 2 cm are repaired using surface sealing, which is a quick repair method using taping. Existing taping generally ranges in width from 2 cm to 5 cm. When used to repair road cracks, it is often done manually on construction sites. Because the road surface has numerous and irregular transverse cracks, the center of the taping needs to be aligned with the cracks, making manual application time-consuming and labor-intensive. This results in low road crack repair efficiency. Utility model content:

[0004] The purpose of the utility model is to provide a road seam tape construction device, and overcome the shortcomings of the above-mentioned prior art, which effectively solves the existing problem of time-consuming and labor-intensive manual pasting of the seam tape.

[0005] Contents of the utility model: A pavement seam tape construction device comprises a support leg, a pallet is mounted on the support leg, a positioning column is coaxially mounted on the pallet, a seam tape fixing assembly is provided on the pallet, a main pressure roller is rotatably connected to the bottom end of the support leg, a seam tape auxiliary pressing assembly is provided on the support leg, the seam tape fixing assembly comprises a screw, the inner end of the screw is vertically and coaxially fixed to the pallet, the positioning column is sleeved on the screw, a nut is threaded on the outer end of the screw, a chuck is sleeved on the screw, and the chuck is located between the positioning column and the nut.

[0006] Furthermore, the seam tape auxiliary pressing assembly includes a swing arm, the inner end of the swing arm is rotatably connected to the support leg, the outer end of the swing arm is rotatably connected to a secondary pressure roller, and a tension spring is connected between the support leg and the swing arm.

[0007] Furthermore, the swing arm is arc-shaped.

[0008] Furthermore, a steering rod is connected to the top end of the support leg.

[0009] Furthermore, the steering rod is obliquely installed on the top end of the supporting leg.

[0010] The beneficial effects of the utility model are as follows: by using the construction device, the seam tape can be quickly pasted on the cracks in the road surface, which not only saves time and effort, reduces the labor intensity of workers, but also improves the efficiency of repairing the cracks in the road surface.

[0012] Figure 2 It is a left view of the utility model;

[0013] Figure 3 This is a diagram of the use state of the utility model;

[0014] In the figure, 1 is a support leg, 2 is a tray, 3 is a positioning column, 4 is a main pressure roller, 5 is a screw, 6 is a nut, 7 is a chuck, 8 is a swing arm, 9 is a secondary pressure roller, 10 is a tension spring, 11 is a steering rod, and 12 is a seam tape. Specific implementation method:

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings:

[0016] like Figures 1 to 3 As shown, a road seam tape construction device includes a support leg 1, a tray 2 is installed on the support leg 1, a positioning column 3 is coaxially installed on the tray 2, a seam tape fixing assembly is provided on the tray 2, a main pressure roller 4 is rotatably connected to the bottom end of the support leg 1, a seam tape auxiliary pressing assembly is provided on the support leg 1, the seam tape fixing assembly includes a screw 5, the inner end of the screw 5 is vertically and coaxially fixed to the tray 2, the positioning column 3 is sleeved on the screw 5, and the outer end of the screw 5 is fixed to the outer end of the screw 5. A nut 6 is screwed onto the end, and a chuck 7 is mounted on the screw 5. The chuck 7 is located between the positioning column 3 and the nut 6. The auxiliary pressing assembly of the seam tape includes a swing arm 8. The inner end of the swing arm 8 is rotatably connected to the support leg 1, and the outer end of the swing arm 8 is rotatably connected to an auxiliary pressure roller 9. A tension spring 10 is connected between the support leg 1 and the swing arm 8. The swing arm 8 is arc-shaped and is connected to a steering rod 11 at the top of the support leg 1. The steering rod 11 is obliquely installed at the top of the support leg 1.

[0017] Specifically, the seam sealing tape 12 can be quickly pasted on the cracks in the road surface by using a construction device.

[0018] In actual use, first, the seam tape 12 is matched and put on the positioning column 3, so that the seam tape 12 is initially placed on the tray 2. At this time, the chuck 7 is inserted into the screw 5, and the nut 6 is connected to the screw 5. Under the limit of the nut 6, the chuck 7 and the seam tape 12 are fit together, thereby further preventing the seam tape 12 from falling off when rotating on the positioning column 3. After the seam tape 12 is installed, the swing arm 8 is rotated to the outside of the leg 1. At this time, the auxiliary pressure roller 9 is away from the main pressure roller 4. Then wrap the end of the sealing tape 12 around the main pressure roller 4, and loosen the swing arm 8. Under the tension of the tension spring 10, the swing arm 8 rotates toward the inside of the support leg 1, and the auxiliary pressure roller 9 further squeezes the sealing tape 12 onto the main pressure roller 4, so that the sealing tape 12 can always be kept in a taut state with the main pressure roller 4 during use. Under the squeezing of the main pressure roller 4, the sealing tape 12 is accurately and quickly pasted on the cracks in the ground; during construction, the on-site workers hold the steering rod 11 with both hands to control the construction device to move along the cracks in the ground.

[0019] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
