Description

Technical Field

[0001] This utility model relates to the field of floor grinding machine technology, specifically to a floor grinding machine drive wheel structure that is easy to maintain. Background Technology

[0002] A floor grinder is a specialized grinding device for floor treatment. It uses a high-speed rotating grinding disc to grind the floor surface. The grinding disc is typically made of hard materials such as diamond or silicon carbide. This disc can remove stains, wear, and aged layers from the floor surface. However, floor grinders often require a drive mechanism to move them during operation. But existing floor grinder drive wheel structures have some shortcomings, such as:

[0003] Application No.: CN202422075320.5 describes a high-efficiency self-moving grinding machine. This device achieves self-movement of the grinding machine without electricity through the cooperation of a power box, guide wheel lifting mechanism and drive wheel, which greatly improves the migration efficiency. However, in actual use, this device is difficult to control the moving speed of the floor grinding machine, which may lead to the problem of difficulty in adjusting the speed when the floor grinding machine is used on its own.

[0004] Therefore, we propose a drive wheel structure for floor grinders that is easy to maintain, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a drive wheel structure for a floor grinder that is easy to maintain, in order to solve the problem mentioned in the background art that the current floor grinders on the market are difficult to control in terms of movement speed, which may lead to the problem that the floor grinder is difficult to adjust in terms of speed when used independently.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a floor grinding machine drive wheel structure that is easy to maintain, including a device body and a drive motor installed inside the device body, wherein the drive end of the drive motor is connected to a gearbox, and a drive wheel body is provided on the outside of the gearbox;

[0007] The main body of the device is equipped with a remote wireless module, and the remote wireless module is connected to a remote controller. The remote controller is electrically connected to the drive motor, and the remote controller circuit is connected to two sets of clutch mechanisms.

[0008] The left and right sides of the main body of the device are respectively connected to a set of clutch mechanisms, and the clutch mechanism includes a cylinder, and a hydraulic cylinder is installed at the bottom of the cylinder. The bottom of the hydraulic cylinder is connected to a transmission pipe, and the bottom of the transmission pipe is connected to two sets of hydraulic grooves. A hydraulic rod is provided on the outside of the hydraulic groove, and a friction damping plate is connected on the outside of the hydraulic rod. The friction damping plate can fit in contact with the inside of the drive wheel body.

[0009] The drive motor and gearbox drive the drive wheel body to move, enabling the drive wheel to move the main body of the device. When adjusting the speed or stopping suddenly, the clutch mechanism can generate friction with the drive wheel, that is, the cylinder generates pressure inside the hydraulic cylinder, causing the hydraulic cylinder to transmit hydraulic oil through the transmission pipe to the hydraulic tank. The hydraulic tank then drives the hydraulic rod and friction damping plate to fit against the inside of the drive wheel body, thereby completing the emergency stop or cooperating with the drive motor to reduce the movement speed of the drive wheel to prevent the device from slipping when used on smooth floors.

[0010] As a preferred technical solution of this utility model, the bottom of the main body of the device is provided with a fixing plate, and the top of the fixing plate is fixedly connected to the drive motor, the remote wireless module and the remote controller.

[0011] The above technical solution enables the fixing plate to rigidly fix the drive motor, remote wireless module and remote controller, avoiding component displacement caused by high-frequency vibration of the grinding machine, ensuring the coaxiality of the drive motor and gearbox, and increasing the stability of the equipment during use.

[0012] As a preferred technical solution of this utility model, the device body is provided with sliding grooves at both the left and right ends, and a slider is provided on the outside of the friction damping plate, and the friction damping plate can be slidably connected to the sliding groove through the slider.

[0013] The above technical solution enables the slider and the groove to cooperate in a guiding manner, restricts the movement trajectory of the friction damping plate, ensures that the friction damping plate is precisely fitted with the friction edge inside the drive wheel body, avoids local wear caused by misalignment, and thus prevents the friction damping plate from misaligning.

[0014] As a preferred technical solution of this utility model, the main body of the device is fixedly connected to the cylinder, and the cylinder is connected to the circuit of the remote control. Furthermore, the outer side of the main body of the device is fixedly connected to the hydraulic cylinder.

[0015] The above technical solution enables the remote control to drive one or both clutch mechanisms through the circuit, thereby adjusting the start and stop of the cylinder. This eliminates the need to approach the high-speed rotating drive wheel, reducing the risk of damage and increasing the device's safety during use.

[0016] As a preferred technical solution of this utility model, the main body of the device fixes the gearbox by a fixing plate, and the outer side of the drive wheel body is provided with a friction edge, and the outer side of the friction damping plate can be attached and fixed to the friction edge.

[0017] The above technical solution enables the friction edge on the outer side of the drive wheel body to fit with the friction damping plate, which can evenly transmit the friction braking force to the drive wheel, avoid deformation of the drive wheel caused by excessive local force, and thus avoid damage to the drive wheel body by the clutch mechanism, thereby increasing the protection of the device during use.

[0018] As a preferred technical solution of this utility model, the outer side of the gearbox is connected to the drive wheel body bearing through the drive shaft, and the drive shaft is located between two sets of friction damping plates.

[0019] The above technical solution enables the drive shaft to be connected to the bearing of the drive wheel body, reducing the rotational resistance of the drive wheel, ensuring smooth operation of the drive wheel, and reducing power loss.

[0020] As a preferred technical solution of this utility model, the main body of the device is rotatably connected to the outside of the drive shaft through a bearing, and a valve body is provided on the outside of the hydraulic cylinder to transmit or discharge hydraulic oil.

[0021] The above technical solution enables the bearings inside the main body of the device to support the outer side of the drive shaft, further enhancing the rotational stability of the drive shaft and preventing bending deformation of the drive shaft caused by cantilever force, thereby increasing the stability of the equipment during operation.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by driving the drive wheel body through the drive motor and gearbox, the drive wheel can drive the main body of the device to move. When adjusting the speed or stopping suddenly, the clutch mechanism can generate friction with the drive wheel, that is, the cylinder generates pressure on the inside of the hydraulic cylinder, so that the hydraulic cylinder transmits hydraulic oil to the hydraulic groove through the transmission pipe. The hydraulic groove will then drive the hydraulic rod and friction damping plate to fit against the inside of the drive wheel body, thereby completing the emergency stop or cooperating with the drive motor to reduce the moving speed of the drive wheel, so as to prevent the device from slipping when used on smooth floors.

[0023] Furthermore, the fixed plate provides a rigid fixation for the drive motor, remote wireless module, and remote controller, preventing component displacement caused by high-frequency vibration of the grinder, ensuring the coaxiality of the drive motor and gearbox, and increasing the stability of the equipment during use.

[0024] Furthermore, by setting up the groove and the slider, the slider can be guided and matched with the groove to restrict the movement trajectory of the friction damping plate, ensuring that the friction damping plate is precisely fitted with the friction edge inside the drive wheel body, avoiding local wear caused by misalignment, and thus preventing the friction damping plate from misaligning.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] To address the issue of difficulty in controlling the movement speed of existing floor grinding machines, which can lead to speed adjustment problems during automatic operation, the following solution is disclosed. Please refer to [link / reference needed]. Figures 1-5 This utility model provides a technical solution: a floor grinding machine drive wheel structure that is easy to maintain, including a device body 1 and a drive motor 2 installed inside the device body 1. The drive end of the drive motor 2 is connected to a gearbox 3, and a drive wheel body 4 is provided on the outside of the gearbox 3.

[0033] The main body 1 of the device is equipped with a remote wireless module 5, and the remote wireless module 5 is electrically connected to a remote controller 6. The remote controller 6 is electrically connected to the drive motor 2, and the remote controller 6 is electrically connected to two sets of clutch mechanisms.

[0034] The left and right sides of the main body 1 are respectively connected to a set of clutch mechanisms, and the clutch mechanism includes a cylinder 8, and a hydraulic cylinder 9 is installed at the bottom of the cylinder 8. The bottom of the hydraulic cylinder 9 is connected to a transmission pipe 10, and the bottom of the transmission pipe 10 is connected to two sets of hydraulic grooves 11. A hydraulic rod 12 is provided on the outside of the hydraulic groove 11, and a friction damping plate 13 is connected on the outside of the hydraulic rod 12. The friction damping plate 13 can fit in contact with the inside of the drive wheel body 4.

[0035] When the clutch mechanism is running, connecting the remote control 6 will drive the cylinder 8 to run. After receiving the signal, the cylinder 8 outputs pressure to squeeze the hydraulic oil inside the hydraulic cylinder 9. The hydraulic oil is transported to the two sets of hydraulic grooves 11 through the transmission pipe 10. The pressure in the hydraulic groove 11 increases and pushes the hydraulic rod 12 to extend outward, which drives the friction damping plate 13 to move closer to the drive wheel body 4, thereby causing the friction damping plate 13 to stop the drive wheel body 4.

[0036] The device body 1 has a fixed plate 16 at the bottom, and the top of the fixed plate 16 is fixedly connected to the drive motor 2, the remote wireless module 5 and the remote controller 6. The device body 1 has sliding grooves 15 at both the left and right ends, and a slider 14 is provided on the outside of the friction damping plate 13. The friction damping plate 13 can be slidably connected to the sliding groove 15 through the slider 14.

[0037] The main body 1 of the device is fixedly connected to the cylinder 8, and the cylinder 8 is connected to the remote controller 6 by circuit. The outer side of the main body 1 is fixedly connected to the hydraulic cylinder 9. The main body 1 fixes the gearbox 3 through the fixing plate 16. The outer side of the drive wheel body 4 is provided with a friction edge 7, and the outer side of the friction damping plate 13 can fit and fix with the friction edge 7.

[0038] The gearbox 3 is connected to the drive wheel body 4 via a drive shaft bearing, and the drive shaft is located between two sets of friction damping plates 13. The main body 1 of the device is rotatably connected to the drive shaft via a bearing, and the hydraulic cylinder 9 is provided with a valve body that can transmit or discharge hydraulic oil.

[0039] Working principle: When using this easy-to-maintain floor grinder drive wheel structure, first connect to an external power source so that the remote wireless module 5 receives the signal and starts the drive motor 2 through the remote controller 6. The drive motor 2 drives the gearbox 3 and the drive wheel body 4. When the remote controller 6 drives one or both sets of clutch mechanisms, the remote controller 6 will drive the cylinder 8. After receiving the signal, the cylinder 8 outputs pressure, squeezing the hydraulic oil inside the hydraulic cylinder 9. The hydraulic oil is delivered to the two sets of hydraulic grooves 11 through the transmission pipe 10. The pressure in the hydraulic grooves 11 increases, pushing the hydraulic rod 12 outward and causing the friction damping plate 13 to move closer to the drive wheel body 4, thereby causing the friction damping plate 13 to stop the drive wheel body 4.

[0040] The slider 14 on the outer side of the friction damping plate 13 slides along the groove 15 of the main body 1 of the device, ensuring that the friction damping plate 13 and the friction edge 7 inside the drive wheel body 4 are precisely fitted. The friction force forms a gradual braking force on the drive wheel body 4, which, together with the drive motor 2 and the gearbox 3, reduces the speed and achieves a smooth reduction in the speed of the drive wheel body 4, avoiding the grinding machine from bumping due to a sudden drop in speed. When working on a smooth floor, the clutch mechanism can also generate resistance through the friction damping plate 13 and the friction edge 7, thereby preventing the drive wheel body 4 from slipping.

[0041] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
