Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a suspended polishing device. Background Technology

[0002] Existing grinding equipment is usually handheld. When grinding large, irregularly shaped parts, workers hold the grinding device and constantly adjust the angle to grind the parts. This grinding method is often labor-intensive, time-consuming, and physically demanding, thus reducing production efficiency.

[0003] While existing suspended grinding devices utilize the lever principle to make the grinding process less strenuous than handheld grinding, the use of chains for suspension allows for a high degree of freedom of movement during processing. Pitching and lateral movements are unrestricted, which can cause the device to sway beyond the grinding area when only pitching is required during processing due to the lack of horizontal constraints.

[0004] The existing suspended grinding devices have non-adjustable baffles and handrails that extend outwards, taking up a lot of space and obstructing other operations when not in use.

[0005] In addition, existing suspended grinding devices are driven by belts. Since the motor and the grinding wheel are driven by the friction between the belt and the pulley, the belt is usually tightly wrapped around the pulley. The positions of the motor and the grinding wheel cannot be moved, making it inconvenient to remove or install the belt.

[0006] To address the problems existing in the prior art, this utility model designs and manufactures a suspended grinding device to overcome the aforementioned defects. Summary of the Invention

[0007] To address the problems existing in the prior art, this utility model provides a suspended grinding device that facilitates the disassembly and installation of the belt and reduces the space occupied.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a suspended grinding device, including a telescopic frame, a lifting ring installed on the upper end of the telescopic frame, a drive motor and a grinding wheel respectively installed at both ends of the telescopic frame, the drive motor and the grinding wheel being connected by a belt, and a handrail installed at the end of the grinding wheel away from the telescopic frame;

[0009] The telescopic frame is rotatably mounted with a slanted baffle at one end away from the grinding wheel. The drive motor is mounted on the side of the slanted baffle away from the telescopic frame. The slanted baffle is provided with an upper locking ring and a lower locking ring. The telescopic frame is provided with an upper hole and a lower hole that cooperate with the upper locking ring and the lower locking ring, respectively.

[0010] A pin is installed on the inclined baffle. When the pin passes through both the upper locking ring and the upper hole, the inclined baffle can maintain an upward tilt along the direction of the telescopic frame. When the pin passes through both the lower locking ring and the lower hole, the inclined baffle is perpendicular to the telescopic frame.

[0011] Preferably, one end of the inclined baffle is hinged to the telescopic frame, and the drive motor is located at the other end of the inclined baffle;

[0012] When the inclined baffle is in a vertical state, the distance between the drive motor and the grinding wheel is less than the distance between the drive motor and the grinding wheel when the inclined baffle is in an inclined state.

[0013] Preferably, the telescopic frame includes a connecting cylinder, in which a first connecting column and a second connecting column are slidably installed. The ends of the first connecting column and the second connecting column that are far apart from each other extend out of the connecting cylinder. A locking component for controlling the extension length of the first connecting column and the second connecting column is installed on the connecting cylinder.

[0014] The inclined baffle is installed on the end of the first connecting column away from the connecting cylinder, and the grinding wheel is installed on the end of the second connecting column away from the connecting cylinder.

[0015] Preferably, the locking assembly includes at least two locking pins, and the first connecting post, the second connecting post, and the side wall of the connecting cylinder are each provided with a plurality of through holes that can cooperate with the locking pins.

[0016] Preferably, the connecting cylinder is provided with a sliding groove, and the outer walls of the first connecting column and the second connecting column are provided with sliders. The first connecting column and the second connecting column are slidably installed in the connecting cylinder through the sliders cooperating with the sliding groove.

[0017] Preferably, the cross-sections of the first connecting column, the second connecting column, and the connecting cylinder are all rectangular.

[0018] Preferably, the handrail includes a mounting block and two rotating rods located on both sides of the mounting block, the rotating rods being fixed to the second connecting column by bolts.

[0019] Preferably, the belt is installed on the same side of the drive motor and the grinding wheel, and a side baffle is installed on the connecting cylinder, the side baffle being located between the belt and the connecting cylinder.

[0020] Preferably, when the telescopic frame is retracted to its shortest length, neither end of the side baffle contacts the drive motor or the grinding wheel.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model has a rotatable inclined baffle mounted on a telescopic frame and is equipped with an upper locking ring, a lower locking ring, an upper hole, and a lower hole to restrict the rotation of the inclined baffle. The inclined baffle can block the sparks generated at the grinding wheel, preventing the flying sparks from affecting the drive motor. During grinding, it can also act as a fulcrum to distribute the force, prevent the grinding wheel from shaking, and reduce the difficulty of operation and the labor intensity of workers.

[0023] 2. This utility model can lift the device by connecting it to the lifting device through the lifting ring. When grinding the workpiece, the worker can operate the grinding wheel to tilt or move it horizontally by using the handrail, which is more labor-saving. The range of motion of the grinding wheel is also increased, which reduces the labor intensity and processing difficulty of the worker and improves the production efficiency.

[0024] 3. The length of the telescopic frame of this utility model is adjustable, which can ensure a safe distance between the grinding wheel and the drive motor during use. It can also finely adjust the length to tighten the belt when it becomes loose to prevent slippage. When the device is not in use, it can be retracted to its shortest length to reduce space occupation and facilitate placement. Attached Figure Description

Detailed Implementation

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1-3 The suspended grinding device shown includes a telescopic frame, with a grinding wheel 9 and a drive motor 4 mounted at each end of the frame. The drive motor 4 and the grinding wheel 9 are connected by a belt 7. The length of the telescopic frame is freely adjustable. During use, this ensures a safe distance between the grinding wheel 9 and the drive motor 4, preventing excessive sparks from hitting the drive motor 4 and affecting its lifespan. When not in use, the telescopic frame can be retracted to its shortest length, reducing space occupation and facilitating placement.

[0031] The telescopic frame of this utility model includes a connecting cylinder 16. A first connecting column 5 and a second connecting column 1 are slidably installed inside the connecting cylinder 16. A sliding groove is provided inside the connecting cylinder 16. A slider is provided on the outer wall of the first connecting column 5 and the second connecting column 1. The first connecting column 5 and the second connecting column 1 are slidably installed inside the connecting cylinder 16 through the cooperation of the slider and the sliding groove. The ends of the first connecting column 5 and the second connecting column 1 that are far apart from each other extend out from inside the connecting cylinder 16.

[0032] The upper end face of the connecting cylinder 16 of this utility model is equipped with a lifting ring 6, the drive motor 4 is installed on the end of the first connecting column 5 away from the connecting cylinder 16, the handrail is installed on the end of the second connecting column 1 away from the connecting cylinder 16, and the grinding wheel 9 is installed between the handrail and the second connecting column 1.

[0033] Specifically, the lifting device lifts the entire device by connecting to the lifting ring 6. The lifting ring 6 is the balance point of the entire device. When grinding the workpiece, the worker can operate the grinding wheel 9 by the handrail to perform pitching or lateral movements more effortlessly, and the range of motion is also increased, which reduces the labor intensity and processing difficulty of the workers and improves production efficiency.

[0034] Specifically, the cross-sections of the first connecting column 5, the second connecting column 1, and the connecting cylinder 16 are all rectangular, which can prevent the first connecting column 5 and the second connecting column 1 from rotating during sliding, thus affecting the transmission and normal operation of the grinding wheel 9 and the drive motor 4.

[0035] The connecting cylinder 16 of this utility model is equipped with a locking assembly for controlling the extension length of the first connecting post 5 and the second connecting post 1. The locking assembly includes at least two locking pins 17. The first connecting post 5, the second connecting post 1, and the side wall of the connecting cylinder 16 are all provided with a number of through holes 15 that can cooperate with the locking pins 17.

[0036] Specifically, after determining the extension length of the first connecting column 5 and the second connecting column 1, a locking pin 17 is inserted into the through hole 15 where the axes coincide, and at least one locking pin 17 is inserted into the through hole 15 of the first connecting column 5 and the second connecting column 1, thereby restricting the relative movement of the first connecting column 5 and the second connecting column 1 with the connecting cylinder 16 and locking the length of the telescopic frame.

[0037] In this invention, a slanted baffle 2 is installed at the end of the first connecting column 5 away from the connecting cylinder 16, and the drive motor 4 is installed on the side of the slanted baffle 2 away from the connecting cylinder 16. The belt 7 is installed on the same side of the drive motor 4 and the grinding wheel 9, and a side baffle 8 is installed on the connecting cylinder 16, located between the belt 7 and the connecting cylinder 16.

[0038] Specifically, the lower end face of the inclined baffle 2 rests against the flat surface during grinding. The inclined baffle 2 acts as a fulcrum against the flat surface, which not only makes grinding more labor-saving, but also limits the horizontal swaying of the device, so that the grinding wheel 9 can only make pitching motion around the lower end face of the inclined baffle 2, avoiding exceeding the grinding range due to swaying, and making the grinding area controllable.

[0039] Specifically, the inclined baffle 2 and the side baffle 8 work together to block the sparks generated at the grinding wheel 9, preventing the flying sparks from affecting the service life of the drive motor 4 and the belt 7. In addition, when the telescopic frame is retracted to its shortest length, neither end of the side baffle 8 contacts the drive motor 4 or the grinding wheel 9, so it will not hinder the retraction of the telescopic frame.

[0040] The inclined baffle 2 of this utility model is rotatably mounted on the first connecting column 5. The inclined baffle 2 is provided with an upper locking ring 14 and a lower locking ring 3. The first connecting column 5 is provided with an upper hole 18 and a lower hole 13 that cooperate with the upper locking ring 14 and the lower locking ring 3 respectively. A pin 19 is installed on the inclined baffle 2.

[0041] Specifically, when the pin 19 passes through both the upper locking ring 14 and the upper hole 18, the inclined baffle 2 can maintain its upward tilt along the direction of the connecting cylinder 16. During the grinding of the workpiece, this blocks and guides the flying sparks towards the ground, improving the safety of the device and preventing sparks from injuring nearby workers.

[0042] Specifically, when the pin 19 passes through both the lower locking ring 3 and the lower hole 13, the inclined baffle 2 is perpendicular to the first connecting post 5. When not in use, the inclined baffle 2 can be rotated to a direction perpendicular to the first connecting post 5 to reduce the overall length of the device and reduce space occupation.

[0043] In this invention, one end of the inclined baffle 2 is hinged to the telescopic frame, and the drive motor 4 is located at the other end of the inclined baffle 2. When the inclined baffle 2 is in a vertical state, the distance between the drive motor 4 and the grinding wheel 9 is less than the distance between the drive motor 4 and the grinding wheel 9 when the inclined baffle 2 is in an inclined state. When installing or removing the belt 7, simply adjust the inclined baffle 2 to be perpendicular to the telescopic frame for easy removal. During operation, simply adjusting the inclined baffle 2 to an inclined state allows for belt tensioning, improving maintenance and installation efficiency.

[0044] The handrail of this utility model includes a mounting block 12 and two rotating rods 10 located on both sides of the mounting block 12. The rotating rods 10 are fixed on the second connecting column 1 by bolts 11. After loosening the bolts 11, the rotating rods 10 can rotate around the bolts 11. In order to facilitate operation, the rotating rods 10 can be rotated to a suitable angle and then the bolts 11 can be tightened to fix them.

[0045] Specifically, when the device is not in use, the angle of the rotating rod 10 can be adjusted to be perpendicular to the telescopic frame. The rotating rod 10 and the inclined baffle 2 are supported on the ground at the same time, which can raise the grinding wheel 9 to avoid contact and collision with the ground, thus extending its service life.

[0046] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
