Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an expansion joint cleaning brush based on a joint cutting machine. Background Technology

[0002] Currently, most expansion joint cleaning work is done manually with steel brushes, which requires workers to squat for long periods of time. This is inefficient, labor-intensive, and difficult to guarantee quality. On the one hand, it is difficult to clean deep into the expansion joints with manual steel brushes. On the other hand, the hardened mud after cutting the joints is difficult to clean manually, which poses potential quality risks.

[0003] Publication number CN220538367U discloses a novel expansion joint cleaning brush based on a seam cutting machine. By setting a drive shaft connecting bolt, the drive shaft clamp is connected to the drive shaft of the seam cutting machine. After connection, starting the seam cutting machine causes all the wire rope brushes to rotate. During rotation, the brushes move along the expansion joint, quickly completing the cleaning. However, this patent still has the following problems in actual use:

[0004] By connecting the drive shaft clamp to the drive shaft of the expansion joint using drive shaft connecting bolts, the expansion joint is cleaned quickly by starting the expansion joint and rotating all the wire rope brushes. However, the expansion joint itself will vibrate during operation, which may cause the installation part of the cleaning brush to loosen, affecting the normal operation of the cleaning brush. At the same time, the vibration may also cause uneven contact between the brush bristles and the expansion joint wall, reducing the cleaning effect.

[0005] A joint cleaning brush based on a joint cutting machine is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an expansion joint cleaning brush based on a seam cutting machine, to solve the problems mentioned in the background art. Currently, the current method involves connecting the drive shaft clamp to the drive shaft of the seam cutting machine using a drive shaft connecting bolt. After connection, starting the seam cutting machine causes all the wire rope brushes to rotate, and during their rotation, they move along the expansion joint to quickly complete the cleaning. However, the seam cutting machine itself generates vibration during operation, which may cause the installation part of the cleaning brush to loosen, affecting the normal operation of the cleaning brush. At the same time, the vibration may also cause uneven contact between the brush bristles and the expansion joint wall, reducing the cleaning effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a joint cleaning brush based on a joint cutting machine, comprising a drive shaft, wherein a drive shaft connecting bolt is fixedly connected to one side surface of the drive shaft;

[0008] A connecting plate is connected through the surface of the drive shaft. Grooves are symmetrically opened on both sides of the inside of the connecting plate. A double-ended lead screw is rotatably connected inside the groove. A wire rope clamp is attached to the surface of the connecting plate. Wire rope brushes are attached to both sides of the wire rope clamp.

[0009] Also includes:

[0010] A buffer assembly is provided on one side surface of the wire rope clamp;

[0011] The buffer assembly includes a stabilizing plate that is fixedly connected to the wire rope clamp.

[0012] Among them, several sleeves are symmetrically installed on the side surface of the stabilizing plate away from the wire rope clamp.

[0013] Preferably, a push rod is sleeved inside the sleeve, a buffer spring is sleeved on the surface of the push rod, a buffer plate is fixedly connected to one side of the buffer spring, and the other side of the buffer spring is fixedly connected to the sleeve.

[0014] Preferably, a plurality of limiting boxes are fixedly installed below the sleeve, and a damping block is fixedly installed inside the limiting box. A damping spring is fixedly connected to the surface of the damping block away from the limiting box.

[0015] Preferably, a connecting rod is fixedly connected to the side surface of the damping spring away from the damping block, and the connecting rod is fixedly connected to the buffer plate by passing through the side surface of the limiting box away from the damping spring.

[0016] Preferably, the buffer plate is made of rubber.

[0017] Preferably, a fixing bolt is connected through the inside of the wire rope clamp, and the wire rope clamp and the wire rope brush are connected by the fixing bolt.

[0018] Preferably, the double-ended lead screw is provided with threaded sleeves on both sides, and the top surface of the threaded sleeves is fixedly connected to the wire rope clamp.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This expansion joint cleaning brush based on a seam cutting machine, by setting a buffer component between two wire rope clamps, buffers the vibration generated during the operation of the seam cutting machine, thereby reducing the vibration force on the wire rope brush. This absorbs and mitigates these vibrations and impacts, reducing damage to the wire rope brush and preventing loosening or breakage of the connection between the brush and the clamps due to long-term vibration, thus extending the service life of the brush. The specific details are as follows:

[0020] 1. By incorporating a buffer assembly, when the cutting machine drives the drive shaft to rotate, the rotation of the drive shaft causes the wire rope brush to rotate, thus cleaning the cut joints in the road surface. Simultaneously, the vibration generated by the cutting machine is transmitted to the wire rope clamp, which in turn transmits the vibration to the buffer plate and the stabilizing plate. The cooperation between the sleeve, push rod, and buffer spring buffers the vibration transmitted to the buffer and stabilizing plates. This vibration is also transmitted to the connecting rod, which in turn... The spring is fixedly connected, and the damping spring is fixedly connected to the damping block. Through the cooperation between the damping block and the damping spring, the vibration force on the connecting rod can be buffered. Thus, through the cooperation between the sleeve, top rod, buffer spring, connecting rod, damping spring and damping block, the vibration force generated when the cutting machine is working can be buffered, thereby reducing the vibration force on the wire rope brush. This absorbs and slows down these vibrations and impacts, reduces damage to the wire rope brush, and avoids loosening and breakage of the connection between the brush and the clamp plate due to long-term vibration, thereby extending the service life of the brush.

[0021] 2. By setting a double-ended lead screw and a threaded sleeve, when clamping wire rope brushes of different thicknesses, rotating the double-ended lead screw causes the threaded sleeve to move. Simultaneously, the threaded sleeve is fixedly connected to the wire rope clamp, which is in contact with the connecting plate. The cooperation between the wire rope clamp and the connecting plate limits the movement of the threaded sleeve, allowing it to move on the double-ended lead screw. Furthermore, when the threaded sleeve moves towards the center or sides, it also moves the wire rope clamp, thus enabling the clamping of wire rope brushes of different thicknesses. The wire rope clamp and the wire rope brush are connected by fixing bolts, ensuring the clamping of the wire rope brush... The brush replacement is also more convenient. When the threaded sleeve moves the wire rope clamp, the wire rope clamp causes the buffer spring and damping spring on the buffer assembly to deform. Due to the characteristics of the buffer spring and damping spring, when the buffer spring and damping spring are subjected to continuous vibration force, the buffer spring and damping spring can still be further stretched or compressed, thereby producing additional elastic deformation. This additional deformation can absorb new energy, thus playing a buffering role. Therefore, when the buffer spring and damping spring are in a stretched or compressed state, they can also buffer the vibration force generated by the cutting machine, thereby providing a certain buffering effect on the wire rope brush.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a joint cleaning brush based on a joint cutting machine, including a drive shaft 1, with a drive shaft connecting bolt 2 fixedly connected to one side surface of the drive shaft 1; a connecting plate 3 is connected through the surface of the drive shaft 1, and grooves 4 are symmetrically formed on both sides of the interior of the connecting plate 3, with a double-headed screw 5 rotatably connected inside the grooves 4; a wire rope clamp 6 is attached to the surface of the connecting plate 3, and wire rope brushes 8 are attached to both sides of the wire rope clamp 6; it also includes: a buffer assembly 7 provided on one side surface of the wire rope clamp 6; wherein, the buffer assembly 7 includes a stabilizing plate 701 fixedly connected to the wire rope clamp 6; wherein, a plurality of sleeves 702 are symmetrically installed on the side surface of the stabilizing plate 701 away from the wire rope clamp 6, such as Figure 1-5 As shown, by setting a buffer component 7 between the two wire rope clamps 6, the vibration generated during the operation of the cutting machine is buffered, thereby reducing the vibration force on the wire rope brush 8, absorbing and slowing down these vibrations and impacts, reducing damage to the wire rope brush 8, avoiding loosening and breakage of the connection between the brush and the clamp due to long-term vibration, and extending the service life of the brush.

[0030] A push rod 703 is fitted inside the sleeve 702. A buffer spring 704 is fitted on the surface of the push rod 703. A buffer plate 705 is fixedly connected to one side of the buffer spring 704, and the other side of the buffer spring 704 is fixedly connected to the sleeve 702. Several limit boxes 706 are fixedly installed below the sleeve 702. A damping block 707 is fixedly installed inside the limit box 706. A damping spring 708 is fixedly connected to the side of the damping block 707 away from the limit box 706. A connecting rod 709 is fixedly connected to the side of the damping spring 708 away from the damping block 707. The connecting rod 709, away from the damping spring 708 and passing through the side of the limit box 706, is fixedly connected to the buffer plate 705. The buffer plate 705 is made of rubber. Figure 3-5 As shown, the vibration force generated during the operation of the cutting machine is transmitted to the wire rope clamp 6, which in turn transmits the vibration force to the buffer plate 705 and the stabilizing plate 701. Simultaneously, through the cooperation of the sleeve 702, the push rod 703, and the buffer spring 704, the vibration force transmitted to the buffer plate 705 and the stabilizing plate 701 is buffered. The vibration force transmitted to the buffer plate 705 and the stabilizing plate 701 is also transmitted to the connecting rod 709, which is fixedly connected to the damping spring 708. The damping spring 708 is fixedly connected to the damping block 707. The cooperation between 707 and damping spring 708 allows for the buffering of vibration force on connecting rod 709. This, in turn, through the cooperation of sleeve 702, push rod 703, buffer spring 704, connecting rod 709, damping spring 708, and damping block 707, buffers the vibration force generated during the operation of the cutting machine. This reduces the vibration force on the wire rope brush 8, absorbing and mitigating these vibrations and impacts, reducing damage to the wire rope brush 8, and preventing loosening or breakage of the connection between the brush and the clamping plate due to long-term vibration, thus extending the brush's service life.

[0031] A fixing bolt 9 is internally connected to the wire rope clamp 6. The wire rope clamp 6 and the wire rope brush 8 are connected by the fixing bolt 9. Threaded sleeves 10 are threaded on both sides of the double-ended screw 5. The top surface of the threaded sleeves 10 is fixedly connected to the wire rope clamp 6. Figure 1 , 2As shown, by setting a double-ended lead screw 5 and a threaded sleeve 10, when clamping wire rope brushes 8 of different thicknesses, rotating the double-ended lead screw 5 causes the threaded sleeve 10 to move. Simultaneously, the threaded sleeve 10 is fixedly connected to the wire rope clamp 6, which is in close contact with the connecting plate 3. The cooperation between the wire rope clamp 6 and the connecting plate 3 limits the movement of the threaded sleeve 10, allowing it to move on the double-ended lead screw 5. When the threaded sleeve 10 moves towards the center or to the sides, it also moves the wire rope clamp 6, thus enabling the clamping of wire rope brushes 8 of different thicknesses. The wire rope clamp 6 and the wire rope brush 8 are connected by fixing bolts 9, making replacement of the wire rope brush 8 more convenient.

[0032] Working principle: Before using this expansion joint cleaning brush based on a seam cutter, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, by first setting up the buffer assembly 7, when the cutting machine drives the drive shaft 1 to rotate, the rotation of the drive shaft 1 will drive the steel wire rope brush 8 to rotate, thereby cleaning the cut joints of the road surface. At the same time, the vibration force generated by the cutting machine during operation will be transmitted to the steel wire rope clamp 6, which will then transmit the vibration force to the buffer plate 705 and the stabilizing plate 701. Simultaneously, through the cooperation between the sleeve 702, the push rod 703, and the buffer spring 704, the vibration force transmitted to the buffer plate 705 and the stabilizing plate 701 can be buffered. Furthermore, the vibration force transmitted to the buffer plate 705 and the stabilizing plate 701 will also be transmitted to the connecting rod 709, and the connecting rod 709, in conjunction with the damping spring... Spring 708 is fixedly connected, and damping spring 708 is fixedly connected to damping block 707. Through the cooperation between damping block 707 and damping spring 708, the vibration force on connecting rod 709 can be buffered. Thus, through the cooperation between sleeve 702, top rod 703, buffer spring 704, connecting rod 709, damping spring 708 and damping block 707, the vibration force generated during the operation of the cutting machine can be buffered, thereby reducing the vibration force on wire rope brush 8. This absorbs and slows down these vibrations and impacts, reduces damage to wire rope brush 8, and prevents the connection between brush and clamp plate from loosening or breaking due to long-term vibration, thereby extending the service life of brush.

[0033] Secondly, by setting up a double-ended lead screw 5 and a threaded sleeve 10, when clamping wire rope brushes 8 of different thicknesses, rotating the double-ended lead screw 5 causes the threaded sleeve 10 to move. Simultaneously, the threaded sleeve 10 is fixedly connected to the wire rope clamp 6, which is in close contact with the connecting plate 3. The cooperation between the wire rope clamp 6 and the connecting plate 3 limits the movement of the threaded sleeve 10, allowing it to move on the double-ended lead screw 5. Furthermore, when the threaded sleeve 10 moves towards the center or to the sides, it also moves the wire rope clamp 6, thus enabling the clamping of wire rope brushes 8 of different thicknesses. The wire rope clamp 6 and the wire rope brush 8 are connected by fixing bolts 9, thus facilitating the clamping of the wire rope brush 8. Replacement is also more convenient. When the threaded sleeve 10 moves the wire rope clamp 6, the wire rope clamp 6 causes the buffer spring 704 and damping spring 708 on the buffer assembly 7 to deform. Due to the characteristics of the buffer spring 704 and damping spring 708, when the buffer spring 704 and damping spring 708 are subjected to continuous vibration force, they can still be further stretched or compressed, thereby generating additional elastic deformation. This additional deformation can absorb new energy, thus playing a buffering role. Therefore, when the buffer spring 704 and damping spring 708 are in a stretched or compressed state, they can also buffer the vibration force generated by the cutting machine, thereby providing a certain buffering effect on the wire rope brush 8.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
