Description

Technical Field

[0001] The utility model relates to the technical field of pavement construction, and specifically refers to a joint cleaning device. Background Art

[0002] The expansion joints of the road surface, also known as expansion joints or contraction joints, are structural elements pre-designed and implemented on the concrete road surface to adapt to the thermal expansion and contraction effects caused by temperature changes. When the external temperature rises, the concrete expands; when the temperature drops, the concrete contracts. Without proper expansion joints, this physical change can cause cracks or even fractures in the road surface.

[0003] The original intention of the design of the expansion joint is to allow the structure to expand and contract freely due to temperature changes, loads or humidity conditions, thus avoiding structural damage. If dust, gravel, sand or other sundries accumulate in the joint, it will hinder the normal operation of the joint, resulting in concentrated structural stress and ultimately may cause cracks or more serious damage. Therefore, in the technical field of pavement construction, construction workers need to regularly clean the expansion joints inside, which requires the use of joint cleaning equipment. However, the traditional joint cleaning equipment has at least the following problems:

[0004] During the process of cleaning the joints by the traditional joint cleaning equipment, due to the high-speed rotation of the cleaning saw blade, the sundries in the joint will be quickly carried out. These sundries mixed with dust will float into the air, polluting the on-site environment, and the small stones and other substances among them need to be cleaned separately after falling to the ground, which is very inconvenient to operate; in addition, the joint cleaning equipment is mostly pushed and operated manually, but in the existing technology, there is a lack of positioning and guiding functions for the forward movement of the equipment, which leads to the cleaning saw blade being easily shifted obliquely by human force during high-speed rotation, affecting the expansion joint.

[0005] In view of this, it is necessary to improve the above defects. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the above defects and provide a joint cleaning device.

[0026] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure. On the contrary, they are merely examples of the devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to the attached drawings of the specification Figures 1 to 4, the present utility model discloses a seam cleaning device, which mainly includes a substrate 1, a driving component 7, a seam cleaning component 12 and a dust collection component 16. Among them, a handrail 26 is fixedly connected to the rear end of the substrate 1, and an inclined part 2 is arranged at the front end of the substrate 1. A rotating shaft 3 is inserted at the bottom end of the inclined part 2, and a wheel shaft 4 is inserted at the rear end of the substrate 1. Both ends of the wheel shaft 4 are respectively fixedly connected with a first wheel 5 and a second wheel 6; the driving component 7 is arranged on the substrate 1, and the driving component 7 includes a motor 8. The bottom end of the motor 8 is fixedly connected with a motor base 22, and the motor base 22 is fixedly connected to the substrate 1. The output shaft of the motor 8 is located on the side close to the second wheel 6. A first pulley 9 is fixedly connected to the output shaft of the motor 8, and a second pulley 10 is fixedly connected to the side of the rotating shaft 3 close to the first pulley 9. A belt 11 is arranged between the first pulley 9 and the second pulley 10 to connect them; the rotation of the output shaft of the motor 8 drives the first pulley 9 to drive the belt 11 to drive the second pulley 10 to rotate, and finally the rotation of the rotating shaft 3 is realized. The seam cleaning component 12 includes a seam cleaning saw blade 13, and the seam cleaning saw blade 13 is fixedly connected to one end of the rotating shaft 3 away from the second pulley 10. Therefore, the rotation of the rotating shaft 3 will drive the seam cleaning saw blade 13 to rotate. During use, the seam cleaning saw blade 13 is aligned with the expansion joint to be cleaned, and then the device is pressed down.

[0029] The seam cleaning saw blade 13 rotates at a high speed to clean the residual debris in the expansion joint, and the debris will fly accordingly. To solve the above problems, a dust collection cover 14 is arranged on the periphery of the seam cleaning saw blade 13 of the present utility model. The bottom end of the dust collection cover 14 is higher than the seam cleaning saw blade 13. A protruding part 23 is arranged on the side of the inclined part 2 close to the dust collection cover 14, and the protruding part 23 is fixedly connected to the side end face of the dust collection cover 14. At the same time, a front edge part 15 is arranged at the front end of the dust collection cover 14, and an air duct 18 is arranged at the top of the front edge part 15 and is connected to the dust collection component 16 behind it through the air duct 18. Specifically, the dust collection component 16 includes a dust collection box 17, and the air duct 18 is connected to the dust collection box 17. The dust collection box 17 is arranged at the rear end of the motor 8, and the dust collection box 17 is fixedly connected to the substrate 1. A pump capable of exhausting air is arranged inside the dust collection box 17. Through the connection between the pump and the air duct 18, the dust and flying debris inside the dust collection cover 14 and the front edge part 15 can be sucked and dropped into the dust collection box 17. A box groove 19 is arranged at the bottom of the rear end of the dust collection box 17, and a dust collection box 20 is arranged inside the box groove 19. Therefore, when the dust collection box 20 is full, it can be pulled out for cleaning.

[0030] On the other hand, in order to ensure that the device will not deviate when cleaning the seam, the present utility model also fixedly connects a positioning ring 21 to the middle part of the first wheel 5. The bottom end of the positioning ring 21 is flush with the bottom end of the seam cleaning saw blade 13 and is in the same straight line plane. Therefore, during use, the positioning ring 21 should be first clamped into the expansion joint to be cleaned, and then the device is operated. The expansion joint guides the forward or backward movement of the device to ensure that the device will not deviate.

[0031] Finally, one side of the bottom end of the inclined part 2 away from the dust collecting cover 14 is fixedly connected with a support rod 24, and a support wheel 25 is arranged at the bottom end of the support rod 24, which is used to provide support for the center of gravity balance of the whole device.

[0032] It should be noted here that the electrical components appearing in this text are all electrically connected to an external main controller and 220V mains power. And the main controller can be a conventional known device such as a computer for control. The detailed descriptions of known functions and known components are omitted in the specific implementation manners of the present disclosure. To ensure the compatibility of the device, the operation means adopted are consistent with the parameters of market instruments.
