Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to a road surface crack sealing tape machine. Background Technology

[0002] During use, asphalt roads may develop cracks and other damage due to factors such as excessive traffic volume, vehicle overloading, and road surface aging. If not repaired in time, these damages can pose safety hazards to drivers and significantly affect the actual lifespan of the road surface.

[0003] Maintenance workers typically apply the grout manually, with one person holding a roll of grout tape, tearing off the adhesive backing with one hand and bending over to apply the tape to the crack. They then step on the tape along the crack to press it down. During the process, the tape easily sticks to the soles of their feet, and it tends to accumulate unevenly at sharp bends, making it difficult to control the quality of the grout application and resulting in low efficiency.

Detailed Implementation

[0030] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a road surface crack sealing tape machine, which includes: a frame 1 and a drive unit;

[0033] The upper end of the frame 1 is fixedly connected to the handle 2;

[0034] The drive unit includes a winding pulley 3, a pressing wheel 4, and a collecting wheel 5. The winding pulley 3 is rotatably connected to the middle of the frame 1. The pressing wheel 4 is rotatably connected to the lower end of the frame 1, and the lower edge of the pressing wheel 4 is lower than the lower end of the frame 1. The collecting wheel 5 is rotatably positioned above the pressing wheel 4 to allow the seam sealing tape 25 to pass through the gap between the collecting wheel 5 and the pressing wheel 4, and to sweep past the lower edge of the pressing wheel 4 and extend backward.

[0035] The working process of a road surface crack sealing tape machine is as follows:

[0036] When using this device, one end of the sealing tape 25 is wrapped around the winding wheel 3, and the other end of the sealing tape 25 passes through the gap between the collecting wheel 5 and the pressing wheel 4, bends downward, sweeps over the periphery of the pressing wheel 4, and extends backward. The user holds the handle 2, and the pressing wheel 4 applies pressure to the backward-extending sealing tape 25. The user pushes the frame 1 forward, and the pressing wheel 4 rolls forward. The sealing tape 25 behind the pressing wheel 4 sticks to the ground, and the pressing wheel 4 drives more sealing tape 25 to be laid on the ground. The adhesive paper 24 bends upward and wraps around the collecting wheel 5. The downward-driven sealing tape 25 drives the collecting wheel 5 to rotate, thereby causing more adhesive paper 24 to wrap around the collecting wheel 5, achieving the function of collecting the adhesive paper 24.

[0037] When using this equipment, the entire weight of the equipment is applied to the contact point between the pressing roller 4 and the sealing tape 25, which can flatten the sealing tape 25. At the same time, no external power is required to collect the adhesive paper 24.

[0038] Specifically, before using this equipment, the joint sealing tape 25 is first wrapped around the periphery of the winding wheel 3, with the adhesive paper 24 facing outwards. Then, the other end of the joint sealing tape 25 is passed through the gap between the collecting wheel 5 and the pressing wheel 4. Then, the adhesive surfaces of the adhesive paper 24 and the joint sealing tape 25 are separated. The adhesive paper 24 is then wrapped around the collecting wheel 5 for a certain length. After the joint sealing tape 25 is bent along the periphery of the pressing wheel 4, the adhesive surface of the joint sealing tape 25 adheres to the ground crack, ensuring that the joint sealing tape 25 covers the ground crack and the adhesive paper 24 is wrapped around the collecting wheel 5 simultaneously.

[0039] This device is easy to use and improves the efficiency of ground crack repair.

[0040] In a specific embodiment, the drive unit further includes a first crank 6, one end of which is rotatably connected to the frame 1 and the other end is rotatably connected to the collecting wheel 5, for making the collecting wheel 5 and the pressing wheel 4 on the same vertical plane.

[0041] In this embodiment, specifically, the collecting wheel 5 is connected to the frame 1 via the first crank 6. When the device is running, the collecting wheel 5 is placed on the upper surface of the sealing tape 25 due to its own weight, so that there is a certain friction between the collecting wheel 5 and the sealing tape 25, which makes it easier for the sealing tape 25 to drive the collecting wheel 5 to rotate.

[0042] Specifically, the lower edge of the collecting wheel 5 corresponds to the upper edge of the pressing wheel 4.

[0043] In a specific embodiment, the drive unit further includes a first tension spring 7, one end of which is connected to the frame 1 and the other end is connected to the middle of the first rocker handle 6.

[0044] In this embodiment, specifically, the middle part of the first crank handle 6 is connected to the frame 1 by the first tension spring 7, which increases the pressure of the collecting wheel 5 on the seam sealing tape 25, thereby further increasing the friction between the collecting wheel 5 and the seam sealing tape 25, so that the rotation of the collecting wheel 5 and the transmission of the seam sealing tape 25 can be synchronized.

[0045] like Figure 5 and Figure 6 As shown, in a specific embodiment, it also includes a leveling disc 8, which is fixedly connected to the middle of the frame 1. The center of the leveling disc 8 is fixedly connected to one end of the threaded rod 9, and the other end of the threaded rod 9 passes through the center hole of the pulley 3 and the compression spring 10 in sequence, and is threadedly connected to the nut 11.

[0046] In this embodiment, specifically, the seam tape 25 wrapped around the periphery of the pulley 3 is in the shape of a disc, and the disc-shaped seam tape 25 is attached to the flat disc 8, thereby ensuring the flatness of the seam tape 25 around the pulley 3 and preventing it from becoming scattered.

[0047] The nut 11 applies a certain pressure to the pulley 3 through the compression spring 10. When the sealing tape 25 is released, the pulley 3 cannot rotate due to inertia, but the compression spring 10 cannot completely prevent the pulley 3 from rotating. There is a certain tension in the sealing tape 25 between the pressing wheel 4 and the pulley 3, so that the sealing tape 25 around the pressing wheel 4 can fit tightly against the pressing wheel 4, thus allowing the sealing tape 25 to cover the ground cracks well.

[0048] In a specific embodiment, a shearing mechanism is also included. The shearing mechanism includes a support shaft 12, a pedal 13, and a shearing blade 14. The support shaft 12 is rotatably connected to the frame 1 between the winding wheel 3 and the pressing wheel 4. The pedal 13 and the shearing blade 14 are arranged sequentially on the axial side of the support shaft 12. The winding wheel 3, the pressing wheel 4, and the shearing blade 14 are in the same vertical plane. The shearing blade 14 is connected to the frame 1 through a second tension spring 15, which is used to drive the shearing blade 14 to rotate upward.

[0049] In this embodiment, specifically, when the device is used to cover a single ground crack with the sealing tape 25, the user steps on the pedal 13, which drives the shearing blade 14 to overcome the tension of the second tension spring 15, so that the lower end of the shearing blade 14 cuts off the sealing tape 25, making it easier to transfer the device to the next ground crack.

[0050] Specifically, it also includes a mounting box 29, one side wall of which is fixedly connected to the frame 1, the lower end of the mounting box 29 is open, the support shaft 12 is rotatably connected to the opposite side wall of the mounting box 29, the pedal 13 is located on the outside of the other side wall of the mounting box 29, the shearing blade 14 is located inside the mounting box 29, one end of the second tension spring 15 is connected to the rear side wall of the mounting box 29, and the other end is connected to the shearing blade 14.

[0051] In a specific embodiment, a counting mechanism is also included. The counting mechanism includes a mounting frame 16, a second crank 17, a step counting wheel 18, and a counter 19. The mounting frame 16 is fixedly connected to the lower end of the frame 1. One end of the second crank 17 is hinged to the upper side of the mounting frame 16. The housing of the counter 19 is fixedly installed on the other end of the second crank 17. The monitoring end shaft of the counter 19 is coaxially connected to the step counting wheel 18.

[0052] In this embodiment, specifically, when the operator holds the handle 2 and pushes the frame 1 forward, the step counting wheel 18 at the other end of the second crank 17 hangs down naturally and contacts the ground. The pressure wheel 4 and the step counting wheel 18 roll synchronously and have the same linear velocity, so that the step counting wheel 18 and the pressure wheel 4 have the same travel distance. The counter 19 measures the travel distance of the step counting wheel 18, and thus measures the travel distance of the pressure wheel 4.

[0053] Specifically, the counter 19 uses a meter counter of model JK86, and the display screen 26 of the counter 19 is fixedly installed on the upper end of the frame 1.

[0054] In a specific embodiment, a third tension spring 20 is also included, one end of which is connected to the mounting bracket 16 and the other end is connected to the other end of the second rocker handle 17.

[0055] In this embodiment, specifically, under the tension of the third tension spring 20, the step counting wheel 18 at the other end of the second rocker 17 is not prone to swinging upward due to ground bumps, so that the step counting wheel 18 can stably stick to the ground, thereby enabling the step counting wheel 18 and the pressure wheel 4 to rotate synchronously.

[0056] In a specific embodiment, a limiting plate 21 is also included, which is fixedly connected to the mounting bracket 16 and is used to limit the downward rotation angle of the second rocker handle 17.

[0057] In this embodiment, specifically, when a single ground crack is covered by the crack sealing tape 25, and it is necessary to lift the device and move it to the next ground crack, when lifting the device, the second crank 17 is against the limiting plate 21 below it, thereby preventing the second crank 17 from rotating downward at a large angle. When the device is moved to the next ground crack, the step counting wheel 18 and the pressing wheel 4 are again synchronously against the ground to achieve the purpose of synchronous counting.

[0058] Specifically, the extension direction of the limiting plate 21 is parallel to the extension direction of the frame 1;

[0059] In a specific embodiment, a support rod 22 is also included, which is fixedly connected to the middle part of the frame 1.

[0060] In this embodiment, specifically, one end of the support rod 22 is fixedly connected to the middle of the frame 1. When it is necessary to wrap new seam tape 25 onto the winding wheel 3, the other end of the support rod 22, the pressing wheel 4, and the lower end of the limiting plate 21 are all on the ground. On this basis, the operator holds the frame 1 with one hand to keep the flat plate 8 in a vertical position, so that the operator can use the other hand to complete the work of wrapping the seam tape 25 around the winding wheel 3.

[0061] like Figure 5 and Figure 7 As shown, in a specific embodiment, it also includes a clamping plate 23. One end of the clamping plate 23 is rotatably connected to the edge of the winding wheel 3 via a pivot 27. The pivot 27 is provided with a torsion spring 28, which is used to drive the other end of the clamping plate 23 to rotate toward the winding wheel 3.

[0062] In this embodiment, specifically, when wrapping the seam sealing tape 25, one end of the seam sealing tape 25 is inserted between the other end of the clamping plate 23 and the winding wheel 3. Under the action of the torsion spring 28, the clamping plate 23 presses the end of the seam sealing tape 25 against the edge of the winding wheel 3. Then, the seam sealing tape 25 is wrapped around the winding wheel 3. On this basis, the seam sealing tape 25 can maintain tension until the seam sealing tape 25 on the winding wheel 3 is completely released, so as to maintain the flatness of the seam sealing tape 25 when the pressing wheel 4 presses it, and ensure the seam sealing quality.

[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
