Description
Technical Field
[0001] This utility model belongs to the field of elevator equipment grinding technology, specifically relating to an elevator equipment grinding device that facilitates the recycling of debris. Background Technology
[0002] An elevator is a mechanical device that transports people and goods vertically or at an angle. It belongs to the category of lifting machinery and is widely used in various types of buildings. Elevator steps are one type of elevator equipment. In order to increase the friction of elevator steps, it is generally necessary to cut grooves into them. After cutting the grooves, there will be burrs in the grooves, which need to be polished.
[0003] When polishing elevator treads, the polishing tools have difficulty removing the burrs in the grooves, resulting in poor polishing effect. Moreover, the debris splashed during polishing falls into the grooves, making it difficult to collect the debris.
[0004] Therefore, a grinding device for elevator equipment that facilitates debris recycling is proposed. Utility Model Content
[0005] This invention provides an elevator equipment grinding device that facilitates debris recycling, with the aim of solving the aforementioned problems.
[0006] This utility model provides an elevator equipment grinding device for easy debris recycling, including a grinding platform. A transparent protective cover is hinged to one outer wall of the grinding platform, and a chip collection groove is formed on the top of the grinding platform. A notch is formed on one inner wall of the chip collection groove. Two limiting blocks are symmetrically arranged on the top of the grinding platform near the inner side of the chip collection groove. An elevator tread is placed on one side of the two limiting blocks, and a plurality of anti-slip grooves are evenly spaced on the top of the elevator tread. A grinding assembly is arranged above the grinding platform. The grinding assembly includes... The device includes a movable frame, on the outer side wall of which a crossbeam is provided. A drive motor is provided on one side of the outer wall of the crossbeam. A rotating disk is fixedly connected to the drive motor through its output end on one side. Four arc plates are provided at equal intervals on one side of the outer wall of the rotating disk. A first polishing block is provided on the outer circumferential surface of each of the four arc plates. A fixed shaft is provided on the inner side of the four arc plates. A ring is provided on the outer circumferential surface of the fixed shaft. A second polishing block is provided on the outer circumferential surface of the ring. A connecting ring is provided on the outer side wall of the fixed shaft. A support plate is sleeved on one end of the fixed shaft.
[0007] Furthermore, a guide bracket and a drive rod bracket are provided at the top of the grinding platform near the outer side of the chip collection groove. The guide bracket is located on the horizontal side of the drive rod bracket and consists of a bracket and a slide rod. The drive rod bracket consists of a servo motor, a trapezoidal ball screw, and a bracket. The servo motor is mounted on the bracket, and the output end of the servo motor is fixedly connected to the trapezoidal ball screw. The slide rod passes through the movable frame and the cross frame, and the movable end of the trapezoidal ball screw is fixedly connected to the movable frame.
[0008] Furthermore, a support rod is provided on the outer wall of the crossbar away from the movable frame. One end of the support rod is provided with an embedded strip, which matches and fits with the anti-slip groove, and the top of the embedded strip is on the same horizontal plane as the top of the elevator tread.
[0009] Furthermore, the outer wall of the movable frame is fitted to the outer wall of the elevator pedal; By adopting the above technical solution, the outer side of the elevator pedal can be limited by the movable frame, which can prevent the elevator pedal from shaking during the grinding process and improve the grinding effect of the elevator pedal.
[0010] Furthermore, the second abrasive block is located inside the anti-slip groove, and the outer wall of the second abrasive block abuts against the inner wall of the anti-slip groove; By adopting the above technical solution, the inner wall of the anti-slip groove can be polished by the circumferential movement of the polishing block two, effectively removing burrs from the anti-slip groove.
[0011] Furthermore, the outer wall of the first abrasive block abuts against the top of the elevator tread. By adopting the above technical solution, the top of the elevator tread can be polished by the circumferential movement of the abrasive block, ensuring that the top of the elevator tread is flat and guaranteeing the quality of subsequent spraying.
[0012] Furthermore, the docking ring and the arc plate are fixedly connected; By adopting the above technical solution, a connecting structure can be formed, which allows the rotating disk to pull the fixed shaft to rotate synchronously, thereby enabling the first and second grinding blocks to move synchronously in a high-speed circumferential direction, thus achieving the grinding of the elevator pedal.
[0013] Furthermore, the transparent protective cover is provided with protrusions that match the notch groove; By adopting the above technical solution, the notch groove can be sealed by setting the protrusion, preventing the debris splashed during the grinding process from flowing out of the notch groove, so that the debris can be fully collected.
[0014] The beneficial effects of this utility model are as follows: This invention, through its grinding component, can not only adaptively adjust the spacing of the anti-slip grooves on the elevator pedal, but also utilize two grinding blocks that move at high speed in the circumferential direction to grind the top of the elevator pedal and the inner wall of the anti-slip groove, respectively, avoiding burr residue, improving the grinding effect of the elevator pedal, and increasing grinding efficiency.
[0015] This invention uses an insert strip to enter the anti-slip groove and move along its inner wall. The insert strip can seal the anti-slip groove after grinding and push out residual debris, thus preventing debris splashed during grinding from falling into the anti-slip groove and causing subsequent recycling trouble.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0019] Example 1 Reference Figure 1-5 This utility model embodiment proposes an elevator equipment grinding device that facilitates debris recycling, including a grinding platform 1, a transparent protective cover 2 hinged to one outer wall of the grinding platform 1, and a chip collection groove 3 opened on the top of the grinding platform 1. A notch 31 is opened on one inner wall of the chip collection groove 3. The transparent protective cover 2 is provided with a protrusion that fits into the notch 31. The notch 31 can be blocked by the protrusion, preventing the chips splashed during the grinding process from flowing out of the notch 31, so that the chips can be fully collected. Two limiting blocks 4 are symmetrically arranged on the top of the grinding platform 1 near the inner side of the chip collection groove 3. An elevator pedal 5 is placed on one side of the two limiting blocks 4. Several anti-slip grooves 51 are evenly spaced on the top of the elevator pedal 5. A grinding assembly 8 is installed above the grinding platform 1. The grinding assembly 8 includes a movable frame 81, the outer wall of which is fitted against the outer wall of the elevator tread 5. The movable frame 81 can limit the outer side of the elevator tread 5 to prevent it from shaking during grinding, thus improving the grinding effect. A crossbeam 82 is installed on the outer wall of the movable frame 81. A drive motor 821 is installed on one side of the outer wall of the crossbeam 82. The drive motor 821 is fixedly connected to a rotating disk 8211 through its output end. Four arc plates 8212 are evenly spaced circumferentially on one side of the outer wall of the rotating disk 8211. A grinding block 8213 is installed on the outer circumferential surface of each of the four arc plates 8212. The outer wall of the grinding block 8213 abuts against the top of the elevator tread 5. The circumferential movement of the grinding block 8213 can grind the top of the elevator tread 5, ensuring that the top of the elevator tread 5 is flat. To ensure the quality of subsequent spraying, a fixed shaft 83 is provided on the inner side of the four arc plates 8212. A ring 831 is provided on the outer circumferential surface of the fixed shaft 83. A second abrasive block 832 is provided on the outer circumferential surface of the ring 831. The second abrasive block 832 is located inside the anti-slip groove 51, and the outer wall of the second abrasive block 832 abuts against the inner wall of the anti-slip groove 51. The circumferential movement of the second abrasive block 832 can polish the inner wall of the anti-slip groove 51. The fixed shaft 83 is provided with a docking ring 833 on the outer side wall of the fixed shaft 83. The docking ring 833 and the arc plate 8212 are fixedly connected to form a connection structure. When the rotating disk 8211 rotates, it can pull the fixed shaft 83 to rotate synchronously, so that the first grinding block 8213 and the second grinding block 832 move synchronously in a high speed in the circumferential direction to grind the elevator tread 5. One end of the fixed shaft 83 is fitted with a support plate 834. Specifically, before polishing the elevator pedal 5, a matching polishing block 832 is selected according to the spacing of the anti-slip grooves 51 on the top of the elevator pedal 5 and the inner width of the anti-slip grooves 51. The installation position of the ring 831 on the fixed shaft 83 is adjusted according to the spacing of the adjacent anti-slip grooves 51 so that the polishing block 832 can abut against the inside of the anti-slip grooves 51. Then, the elevator pedal 5 is placed on the top of the polishing platform 1, and one side wall of the elevator pedal 5 is attached to the limiting block 4. The elevator pedal 5 is located inside the moving frame 81. After the elevator pedal 5 is placed in the limiting position, the polishing component 8 can be driven to move linearly along the elevator pedal 5 through the guiding and driving functions of the guide bracket 6 and the drive rod bracket 7. The polishing component 8 is used to polish the elevator pedal 5. The control drive motor 821 drives the rotating disk 8211 to rotate at high speed through its output end on one side. The arc plate 8212 on the rotating disk 8211 rotates synchronously. Under the connection of the docking ring 833, the fixed shaft 83 and the ring 831 rotate synchronously. At this time, the first grinding block 8213 and the second grinding block 832 move synchronously in the circumferential direction at high speed. This not only grinds the top of the elevator tread 5, but also grinds the burrs in the anti-slip groove 51.
[0020] Example 2 Reference Figure 1 Based on the above embodiments, this utility model embodiment also proposes an elevator equipment grinding device that facilitates debris recycling, including a grinding platform 1. A guide bracket 6 and a drive rod bracket 7 are provided at the top of the grinding platform 1 near the outer side of the chip collection groove 3. The guide bracket 6 is located on the horizontal side of the drive rod bracket 7. The guide bracket 6 is composed of a bracket and a slide rod. The drive rod bracket 7 is composed of a servo motor, a trapezoidal ball screw and a bracket. The servo motor is mounted on the bracket, and the output end of the servo motor is fixedly connected to the trapezoidal ball screw. The slide rod passes through the movable frame 81 and the cross frame 82. The movable end on the trapezoidal ball screw is fixedly connected to the movable frame 81. Specifically, in order to achieve stable linear movement of the grinding component 8 along the elevator tread 5, the control servo motor drives the trapezoidal ball screw to rotate through its output end on one side. The moving frame 81 on the trapezoidal ball screw moves, and under the guidance of the slide rod, the moving frame 81 and the cross frame 82 move linearly along the elevator tread 5, thereby grinding the top of the elevator tread 5 and the inner wall of the anti-slip groove 51.
[0021] A support rod 84 is provided on the outer wall of the cross frame 82 away from the movable frame 81. An embedded strip 85 is provided at one end of the support rod 84. The embedded strip 85 matches and fits the anti-slip groove 51, and the top of the embedded strip 85 is on the same horizontal plane as the top of the elevator tread 5. Specifically, to prevent debris from falling into the anti-slip groove 51 after polishing, when the moving frame 81 and the cross frame 82 move in a straight line along the elevator tread 5, the insert strip 85 moves synchronously under the connection of the support rod 84. As the insert strip 85 moves, it enters the anti-slip groove 51 and moves along its inner wall. The insert strip 85 seals the anti-slip groove 51 after polishing and can also push out the remaining debris. When the insert strip 85 is fully embedded in the anti-slip groove 51, the top of the insert strip 85 and the top of the elevator tread 5 are on the same horizontal plane. At this time, the debris falling from the top of the elevator tread 5 is swept away, and the debris falls into the chip collection groove 3 and can be taken out from the notch groove 31.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
