Description

Technical Field

[0001] This application relates to the field of highway maintenance technology, specifically to a handheld road surface crack sealing machine. Background Technology

[0002] In road maintenance, crack sealing tape can effectively seal road surface cracks, preventing rainwater and snowmelt from seeping into the roadbed, avoiding further crack expansion, and extending the road's service life. At the same time, it has excellent adhesion properties, allowing it to adhere tightly to the road surface and adapt to its expansion and contraction.

[0003] In existing technologies, the application of crack sealing tape mainly relies on manual operation by operators. After separating the adhesive layer and the release film, the adhesive layer is then applied to the crack in the ground. This operation involves huge labor costs and requires operators to frequently stand up and sit down, which is quite harmful to their health. There are also some auxiliary crack sealing devices in the existing technology. For example, the crack sealing tape machine for highway pavement cracks disclosed in patent number: CN201910354793.X can effectively reduce labor costs, but it is not flexible enough in use, and there are certain difficulties in transportation and transfer. Utility Model Content

[0004] In view of the above problems, this application provides a handheld road surface sealing machine that can assist operators in applying sealing tape. It is compact, easy to transport, and convenient and efficient to operate.

[0005] According to one aspect of the embodiments of this application, a handheld road joint sealing machine is provided. The handheld road joint sealing machine includes a main structural beam and a rotating rod. The rotating rod is hinged to the main structural beam at its middle section. A first handrail is provided at one top end of the main structural beam. A compaction wheel is rotatably mounted on one side of the bottom end of the main structural beam. A take-up wheel corresponding to the compaction wheel is provided at the bottom end of the rotating rod. A turntable for storing sealing tape is rotatably mounted on one side of the middle section of the main structural beam. An adjustment groove is formed on one side of the middle section of the main structural beam. A slider is provided in the adjustment groove, and a groove is formed on the side wall of the adjustment groove. The slide is provided with a slide rail that matches the slide. One end of the top of the main structural beam has an inner hole along the axial direction of the main structural beam. The inner hole extends and communicates with the adjustment groove. A threaded rod is rotatably connected to one side of the adjustment groove. The threaded rod passes through and is screwed to the slide. The end of the threaded rod away from the adjustment groove extends to the top of the main structural beam and is connected to a servo motor. An elastic component is connected to the bottom of the slide. The other end of the elastic component is connected to the tail end of the rotating rod.

[0006] In some embodiments, a diversion card is fixed on the main structural beam between the turntable and the rolling wheel. The diversion card has a strip groove in the middle, and the sidewalls of the strip groove are provided with smooth chamfers.

[0007] In some embodiments, a limiting groove is formed at one bottom end of the main structural beam, the middle part of the rotating rod is hinged in the limiting groove, and the bottom end of the rotating rod and the bottom end of the main structural beam are aligned with each other.

[0008] In some embodiments, the servo motor includes a control component disposed on the side of the main structural beam near the first handrail portion.

[0009] In some embodiments, the turntable includes a turntable body, a threaded hole is provided on the side of the turntable body away from the main structural beam, a threaded post is screwed into the threaded hole, and a circular cover plate is fixedly connected to the side of the threaded post away from the threaded hole, the diameter of the circular cover plate being larger than the diameter of the turntable body.

[0010] In some embodiments, a narrow neck is provided in the middle of the main structural beam, and the narrow neck constitutes a second handrail portion.

[0011] The beneficial effects of this application are as follows: By configuring the main structural beam, rotating rod, rolling wheel, winding wheel, turntable, and elastic components to work together, the operator only needs to hold the first handle and push the rolling wheel against the ground crack to apply the sealing tape. Simultaneously, the winding wheel can roll up the release film onto it. The winding wheel has no power source and rotates only through friction with the rolling wheel. Furthermore, by configuring a sliding groove and slider, and cooperating with a servo motor and threaded rod, the servo motor, when activated, drives the slider via the threaded rod. During the slider's movement, the stretching degree of the elastic components can be changed, thereby adjusting the pressure between the rolling wheel and the winding wheel. As the sealing work continues, the operator adjusts the position of the sliding block to keep the friction between the rolling wheel and the winding wheel within a reasonable range.

[0021] For details, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of the handheld road surface sealing machine provided in the embodiments of this application. Figure 2 This is a schematic diagram of the overall structure of the device provided in an embodiment of this application from another perspective. Figure 3The schematic diagram of the overall structure of the device in use provided in this application embodiment is shown. Figure 4 This application provides a partial cross-sectional structural diagram of the main structural beam. The handheld road surface sealing machine 100 includes a main structural beam 110 and a rotating rod 120. The rotating rod 120 is hinged at the middle of the main structural beam 110. Both the main structural beam 110 and the rotating rod 120 can be constructed of steel. For ease of fabrication, both the main structural beam 110 and the rotating rod 120 can be made of rectangular steel. After hinge, the main structural beam 110 and the rotating rod 120 form a scissor shape with one leg slightly longer. A first handrail 111 is provided at one end of the top of the main structural beam 110 for the operator to hold. A rolling roller 130 is rotatably mounted on one side of the bottom end of the main structural beam 110. A winding roller 140, corresponding to the rolling roller 130, is mounted on the bottom end of the rotating rod 120. The rolling roller 130 and the winding roller 140 correspond to the adhesive layer and film layer of the joint sealing tape, respectively. The rolling roller 130 presses the adhesive layer to adhere to the cracks in the ground, while the winding roller 140 temporarily stores the film layer around its outer periphery. A turntable 150 for storing the joint sealing tape is rotatably mounted on one side of the middle section of the main structural beam 110. The turntable 150 is used to install the roll of joint sealing tape, which is similar in shape to double-sided tape and is generally coiled up. An adjustment groove 112 is provided on one side of the middle section of the main structural beam 110. A slider 113 is installed in the adjustment groove 112 and can slide within the adjustment groove 112. A sliding groove is provided on the side wall of the adjusting groove 112, and a sliding rail matching the sliding groove is provided at the slider 113. The sliding rail and the sliding groove limit the slider 113 during sliding, ensuring that the slider 113 can only move along the axial direction of the main structural beam 110. An inner hole 114 is provided at one end of the top of the main structural beam 110 along the axial direction of the main structural beam 110. The inner hole 114 extends and connects to the adjustment groove 112. A threaded rod 115 is rotatably connected to one side of the adjustment groove 112. The threaded rod 115 passes through and is screwed to the slider 113. The end of the threaded rod 115 away from the adjustment groove 112 extends to the top of the main structural beam 110 and is connected to a servo motor 116. The servo motor 116 can drive the threaded rod 115 to rotate. During the rotation of the threaded rod 115, it will further drive the slider 113 to move. An elastic component 160 is connected to the bottom of the slider 113. The other end of the elastic component 160 is connected to the tail end of the rotating rod 120. Under the tension of the elastic component 160, the outer walls of the rolling wheel 130 at the front end of the main structural beam 110 and the winding wheel 140 at the front end of the rotating rod 120 will always be in close contact, so that the rolling wheel 130 can synchronously drive the winding wheel 140 to rotate during the rotation process.

[0022] In this embodiment, during operation, the sealing tape is first installed on the turntable 150. Then, the end of the sealing tape is led out and passed through the gap between the rolling roller 130 and the take-up roller 140 to separate the adhesive layer and the film layer. The film layer is flipped upwards and wound around the take-up roller 140 2-3 times. The adhesive layer is then wrapped around the rolling roller 130 and applied close to the ground crack. The operator then holds the first handle 111 and moves the entire device along the crack. During this process, the rolling roller 130 remains in close contact with the ground. Under friction, the rolling roller 130 rotates and continuously applies the adhesive layer to the ground crack. Simultaneously, because the rolling roller 130 and the take-up roller 140 are close to each other, the rotation of the rolling roller 130 synchronously drives the take-up roller 140. The winding wheel 140 rotates and winds up the film layer onto it. After working for a period of time, the number of isolation film layers wound on the winding wheel 140 increases, and the gap between the winding wheel 140 and the rolling wheel 130 increases, which further causes the elastic component 160 to be tightened. At this time, the isolation film between the winding wheel 140 and the rolling wheel 130 is subject to increased friction between the winding wheel 140 and the rolling wheel 130, making it difficult for the equipment to move. At this time, the servo motor 116 can be turned on. During the rotation of the threaded rod 115 driven by the servo motor 116, the slider 113 will move in the direction close to the first handrail 111. At this time, the included angle between the elastic component 160 and the rotating rod 120 will increase, and the two ends of the elastic component 160 will come together and reduce the prestress. At this time, the friction can be reduced to facilitate continued operation.

[0023] As can be seen from the above, in this embodiment of the application, by setting the main structural beam 110, rotating rod 120, rolling wheel 130, winding wheel 140, turntable 150 and elastic element and other components to cooperate with each other, the operator only needs to hold the first handle 111 and push the rolling wheel 130 of the device against the ground crack to achieve the pasting of the crack sealing tape. The winding wheel 140 can simultaneously roll up the release film onto it. The winding wheel 140 has no power device and only needs to rely on the friction between it and the rolling wheel 130 to achieve rotation. On the other hand, this application sets up a slide groove and a slider 113, with the servo motor 116 and the threaded rod 115 cooperating with each other. This allows the servo motor 116 to drive the slider 113 to move through the threaded rod 115 after it is turned on. During the movement of the slider 113, the stretching degree of the elastic component 160 can be changed, thereby adjusting the pressure between the pressing wheel 130 and the winding wheel 140. As the seam sealing work continues, the operator adjusts the position of the sliding block to keep the friction between the pressing wheel 130 and the winding wheel 140 within a reasonable range.

[0024] In some embodiments, a diversion card 170 is fixed on the main structural beam 110 between the turntable 150 and the rolling roller 130. The diversion card 170 has a strip-shaped groove in its center, and the sidewalls of the strip-shaped groove are all provided with smooth chamfers. In this embodiment, during operation, after the sealing tape is led out, it preferentially passes through the strip-shaped groove, and then the adhesive layer is rolled up onto the rolling roller 130. The release layer is then rolled up onto the take-up roller 140, thereby restricting and guiding the direction of the sealing tape.

[0025] In some embodiments, a limiting groove 117 is formed at one bottom end of the main structural beam 110, and the middle part of the rotating rod 120 is hinged in the limiting groove 117, with the bottom end of the rotating rod 120 and the bottom end of the main structural beam 110 aligned with each other. In this embodiment, through the above arrangement, the integrity between the rotating rod 120 and the main structural beam 110 is greatly enhanced, which can reduce the failure rate during equipment use.

[0026] In some embodiments, the servo motor 116 includes a control component 116a, which is disposed on the side of the main structural beam 110 near the first handrail portion 111. In this embodiment, with the above configuration, the operator can grip the first handrail portion 111 and operate the servo motor 116 using only one hand.

[0027] In some embodiments, the turntable 150 includes a turntable body 151. A threaded hole 152 is provided on the side of the turntable body 151 opposite to the main structural beam 110. A threaded post 153 is screwed into the threaded hole 152. A circular cover plate 154 is fixedly connected to the side of the threaded post 153 opposite to the threaded hole 152. The diameter of the circular cover plate 154 is larger than the diameter of the turntable body 151. In this embodiment, during operation, after the seam tape is installed on the turntable 150, the threaded post 153 is screwed into the threaded hole 152. At this time, the circular cover plate 154 will block the seam tape, preventing it from slipping out of the turntable body 151.

[0028] In some embodiments, a narrow neck is provided in the middle of the main structural beam 110, which constitutes a second handrail portion 118. In this embodiment, by providing a second handrail portion 118, the operator's second arm can grip the equipment, reducing the difficulty of operation.
