DETAILED DESCRIPTION

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a road marking line removal device, comprising a cleaner 1 and a pull rod 2 for pulling the cleaner 1 to move; the cleaner 1 comprises a mobile frame 10, on which a scraping assembly 12 and a flame spraying assembly 14 are provided, and the mobile frame 10 is also provided with an observation hole 11 for users to observe the scraping of the marking line; the scraping assembly 12 comprises a tool holder 19 and a scraper 115 mounted on the tool holder 19, and the tool holder 19 passes through the mobile frame 10 through a limiting portion 110 provided therein and is connected to a bracket 113 provided on the upper surface of the mobile frame 10; the flame spraying assembly 14 comprises a voltage regulator tube 116 fixed on the mobile frame 10; wherein, flame spraying heads 16 are evenly distributed in the length direction of the voltage regulator tube 116, and the flame direction of the flame spraying head 16 is directly opposite to the forward direction of the scraper 115.

[0021] In summary, the fuel at the flame head 16 is ignited by an open flame, and then the cleaner 1 is pulled to move, and the scraper 115 moving with the cleaner 1 scrapes off the marking line on the ground.

[0022] Based on this, due to the setting of the observation hole 11, the user can understand the scraping situation of the marking line in real time. At the same time, through the back and forth movement of the pull rod 2, the scraper 115 can be prompted to move back and forth on the marking line to improve the scraping efficiency of the device for the marking line; further, since the flame direction of the flame head 16 is facing the forward direction of the scraper 115, the scraper 115 can immediately scrape it off after the flame softens the marking line, thereby further improving the device's marking line removal efficiency. At the same time, the setting of the voltage regulator tube 116 makes the amount of gas sprayed by each flame head 16 more stable, thereby reducing the phenomenon of flameout of some flame heads 16.

[0023] Furthermore, a threaded rod 111 is further provided on the upper end surface of the limiting portion 110 , and the threaded rod 111 passes through the provided spring 112 and the bracket 113 and then is threadably matched with the provided nut 114 .

[0024] In summary, when the limiting portion 110 passes through the limiting hole set on the mobile frame 10, and the cross-sections of the limiting portion 110 and the limiting hole are both polygonal, the axial rotation of the tool holder 19 can be avoided. At the same time, the setting of the spring 112 can prompt the tool holder 19 to move downward, so that the blade of the scraper 115 can penetrate into the bottom layer of the marking line. When the scraper 115 encounters resistance, it can slide upward, so the service life of the scraper 115 can be extended. In particular, after the resistance ends, the spring 112 can again prompt the scraper 115 to penetrate into the bottom layer of the marking line to ensure the scraping efficiency of the scraper 115 on the marking line; in addition, the nut 114 is threadedly matched with the threaded rod 111, so by rotating the nut 114, the gap between the tool holder 19 and the ground can be adjusted to further ensure the cleaning efficiency of the marking line of the device. Based on this, through the above scheme, while improving the scraping efficiency of the scraping assembly 12, the stability of the scraping assembly 12 during movement can also be guaranteed.

[0025] On the basis of the above scheme, the voltage regulator tube 116 is movably connected to the positioning frame 18 provided on the upper surface of the mobile frame 10 through the connecting pipe 117, and the positioning frame 18 is connected to the fuel tank 13 provided on the upper surface of the mobile frame 10 through a pipeline. Therefore, the device can bring its own fuel to extend the working time of the device; at the same time, the voltage regulator tube 116 can be fixed to the mobile frame 10 by using the positioning frame 18. Among them, the positioning frame 18 can be fixed to the mobile frame 10 by passing the flange provided in the radial direction of the positioning frame 18 through the bolt and connecting it with the internal threaded hole reserved on the mobile frame 10.

[0026] In order to facilitate the installation and replacement of the voltage regulator tube 116, the connecting tube 117 is movably connected to the positioning frame 18 through one end of the mobile frame 10 through the connecting piece 17. Specifically, the connecting piece 17 has threads inside, and the internal threads are used to thread with the positioning frame 18 and the connecting tube 117.

[0027] In order to facilitate the installation of the tie rod 2, a traction seat 15 is further provided at one end of the mobile frame 10 away from the fuel tank 13, and one end of the tie rod 2 is movably connected to the traction seat 15. Specifically, the traction seat 15 is fixed to the mobile frame 10 by passing a bolt through the traction seat 15 and then connected to the internal threaded hole reserved in the mobile frame 10, and then the axle pin rod provided in the middle of the traction seat 15 passes through one end of the tie rod 2 and is connected to a nut to realize the assembly of the tie rod 2 and the mobile frame 10. At the same time, one end of the tie rod 2 is rotatably connected to the axle pin rod in the middle of the traction seat 15, so that the tie rod 2 can rotate along the axle pin rod when in use.

[0028] In order to prevent the flame from moving from the observation hole 11 to the top of the movable frame 10 and causing a safety accident, the observation hole 11 is opened in the width direction of the movable frame 10, and a transparent partition is installed above the observation hole 11. Therefore, the partition can block the flame from rising and also block the influence of heat radiation on the fuel tank 13; specifically, the partition is preferably fire-resistant glass.

[0029] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
