Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to a device for cutting and recycling elevator guide rail scraps. Background Art

[0002] Elevator guide rails are metal structures that provide guidance for the elevator car and counterweight during operation, as well as support during safety brake braking. After a long period of elevator use, the guide rails need to be repaired and replaced. In order to ensure the reuse of resources, elevator guide rails need to be cut and recycled.

[0003] In existing elevator guide rails, T-shaped and L-shaped structures are commonly used. During cutting, to ensure cutting results, these uniquely structured guide rails are often clamped in place using fixtures. However, existing fixtures typically clamp the guide rails horizontally (i.e., applying limiting force from both sides). Therefore, under the downward stress of the blade during cutting, the guide rails are prone to shifting and warping. Shifting can lead to cutting misalignment, affecting the cutting effect. Warping, centered on the cutting point, is caused by the downward stress of the blade, resulting in the ends of the guide rails on both sides of the cutting point warping upwards. These upward-warping guide rails press against and squeeze the sides of the cutting blade, causing the cutting blade to jam. This seriously affects the safe operation of the cutting process and poses a significant safety hazard. Summary of the Invention

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Reference Figures 1-14 This invention includes an elevator guide rail scrap cutting and recycling device, comprising a workbench 1, two sets of positioning and clamping units 2 symmetrically arranged on both sides of the workbench 1, and a cutting and recycling unit located between the two sets of positioning and clamping units 2. The positioning and clamping unit 2 is composed of two sets of symmetrically arranged horizontal fixing parts 3 and two sets of symmetrically arranged vertical fixing parts 4, and each set of vertical fixing parts 4 is correspondingly arranged on each set of horizontal fixing parts 3.

[0038] Reference Figure 14The horizontal fixing component 3 can apply a horizontal positioning and clamping force, while the vertical fixing component 4 can apply a vertical positioning and clamping force. The symmetrical arrangement of the horizontal fixing components 3 allows them to apply clamping force from both sides inwards simultaneously. This clamping method from both sides inwards can center and straighten the guide rail 8 located between the two sets of horizontal fixing components 3, avoiding the formation of an inclined clamping state and eliminating the phenomenon of clamping deviation. The two sets of vertical fixing components 4 with symmetrical postures can also apply a vertical positioning and clamping force to the guide rail 8 from both sides.

[0039] The horizontal fixing component 3 includes a sliding component 31 slidably connected to the worktable 1, a fixing component 32 horizontally disposed at the top of the sliding component 31, and an abutting component 33 horizontally inserted into one side of the fixing component 32. The abutting component 33 includes two sets of symmetrically arranged push rods 331, a hexagonal shaft 332 disposed at one end of the push rod 331 and having a hexagonal prism structure, an abutting block 333 horizontally disposed at the other end of the push rod 331, and a spiral groove 334 opened on the outer wall of each set of push rods 331, and the spiral groove 334 having a spiral structure.

[0040] Reference Figure 3 and Figure 4 The abutting component 33 is the first part to contact the guide rail 8, and can abut and clamp the guide rail 8 from the side. The spiral groove 334 of the spiral structure is evenly coiled on the push rod 331, and there are two sets of spiral grooves 334. The two sets of spiral grooves 334 are coiled around the push rod 331 in a ring with the axis of the push rod 331 as the center point.

[0041] The vertical fixing component 4 includes two sets of transmission components 41 symmetrically rotatably disposed on one side of the fixing component 32, a pressing component 42 located between the two sets of transmission components 41, and a pressing component 43 horizontally inserted into the bottom end of the pressing component 42. The transmission component 41 includes a transmission gear 413 rotatably connected to the side of the fixing component 32, and a transmission shaft 414 disposed on the inner wall of the transmission component 41, with the outer end of the transmission shaft 414 extending into the spiral groove 334. The pressing component 42 is slidably inserted into the side of the fixing component 32 in the vertical direction, and racks 422 that mesh with the transmission gear 413 are provided on both sides of the pressing component 42.

[0042] Reference Figure 4 and Figure 7The transmission component 41 is rotatably connected to the side of the fixed component 32, and the transmission shaft 414 on the transmission component 41 extends into the spiral groove 334. The push rod 331 can only translate and cannot rotate. Therefore, when the push rod 331 moves, it will squeeze and push the transmission shaft 414 through its own spiral structure. The squeezed transmission shaft 414 can only release the pressure by driving the transmission component 41 to rotate. The rotating transmission component 41 pushes the pressing component 42 to slide vertically on the side of the fixed component 32 through the meshing of the external transmission gear 413 and the rack 422, thereby realizing the function of applying a vertical positioning and clamping force.

[0043] Among them, reference Figure 9 and Figure 10 The workbench 1 has two sets of parallel sliding grooves 11, and the sliding component 31 is vertically inserted into the sliding groove 11. The sliding component 31 includes a sliding frame 311 vertically inserted into the sliding groove 11, a threaded bushing 312 disposed at the end of the sliding frame 311, a limiting block 313 disposed on both sides of the sliding frame 311, and a clearance groove 314 disposed on the inner side of the sliding frame 311. The sliding component 31 is inserted into the sliding groove 11 through the sliding frame 311 and is held in the sliding groove 11 by the limiting block 313. At the same time, it is limited by the sliding groove 11 and can slide horizontally along the sliding groove 11. The clearance groove 314 is used to avoid and accommodate the ejector component 44.

[0044] Among them, reference Figure 3 and Figure 6 The fixing component 32 includes a mounting block 321 fixedly disposed on the top of the sliding frame 311, limiting rings 322 symmetrically disposed on one side of the mounting block 321, and the transmission component 41 inserted into the limiting rings 322. A T-slot 323 is formed between the two sets of limiting rings 322, and the side of the pressing component 42 is vertically inserted into the T-slot 323. Hexagonal slots 324 are formed inside both sides of the mounting block 321, and the push rod 331 extends into the hexagonal slot 324. The shape of the hexagonal slot 324 matches the hexagonal shaft 332. A spring 34 is disposed within the hexagonal slot 324. The limiting rings 322 are used to limit the transmission component 41, so that... The transmission component 41 cannot disengage from the limiting ring 322, but it can rotate around itself within the limiting ring 322. The hexagonal groove 324, through its matching structure with the hexagonal shaft 332, can restrict the hexagonal shaft 332, allowing it to slide horizontally along the hexagonal groove 324. This restricts the push rod 331, which is fixedly connected to the hexagonal shaft 332, from rotating. The spring 34, through its elastic support, pushes the hexagonal shaft 332 outward, ensuring that the push rod 331 is always extended out of the hexagonal groove 324. In other words, the entire abutment component 33 is always in an outward-extending state.

[0045] Among them, reference Figure 3 and Figure 7 The transmission assembly 41 includes a sleeve 411 inserted into the limiting ring 322 and a baffle 412 fixedly disposed at one end of the sleeve 411. The diameter of the baffle 412 is larger than the inner diameter of the limiting ring 322. The transmission assembly 41 is rotatably connected to the limiting ring 322 through the sleeve 411, and can maintain a constant connection with the limiting ring 322 through the limiting of the baffle 412, and will not fall off.

[0046] Furthermore, refer to Figure 7 The pressing component 42 also includes a T-shaped slider 423 fixedly connected to the back side of the pressing block 421, and the T-shaped slider 423 is slidably inserted into the T-shaped groove 323 in the vertical direction. Through the cooperation of the T-shaped slider 423 with the T-shaped groove 323, the pressing component 42 can only move vertically on the side of the fixed component 32.

[0047] Among them, reference Figure 7 The pressing assembly 43 includes a horizontal plate 431 inserted into the bottom of the pressing assembly 42, a pressure plate 432 arranged laterally on the outer end of the horizontal plate 431, and a slot 433 opened inside the pressure plate 432. The horizontal plate 431 allows the pressing assembly 43 to move horizontally at the bottom of the transmission assembly 41. The pressure plate 432 has an inverted L-shaped structure, which can increase the contact area with the bottom and the guide rail 8. The slot 433 is used to install the ejection assembly 44.

[0048] Furthermore, refer to Figure 5 and Figure 7 The vertical fixing component 4 also includes an ejection component 44 disposed in the slot 433. The ejection component 44 includes a push rod 441 disposed between the horizontal plate 431 and the sliding component 31, with one end of the push rod 441 extending into the slot 433, and a spring 442 disposed at one end of the push rod 441, with the spring 442 entirely located in the slot 433. The rack 422 provides elastic support to push the push rod 441 out and extend it into the relief groove 314. The overall function of the ejection component 44 is to push the pressing component 43 outward at all times, so that the pressure plate 432 is parallel and attached to the bottom of the abutment block 333, with the outer ends of both on the same vertical line, ensuring that both can contact the guide rail 8 simultaneously and accurately, avoiding problems of inaccurate or improper clamping.

[0049] Among them, reference Figure 9 and Figure 10The bottom of the workbench 1 is provided with a driving component 6. The driving component 6 includes a horizontally arranged driving shaft 61, a motor 62 connected to one end of the driving shaft 61, two sets of screws 63 correspondingly arranged below the two sets of slide grooves 11, and the end of the sliding component 31 is threadedly connected to the screw 63. Two sets of bevel gears 64 are arranged on the driving shaft 61 and corresponding to the position of the screw 63. A bevel gear 65 is arranged at one end of the screw 63 and meshes with the bevel gear 64. The driving shaft 61 is rotatably arranged on the workbench 1. The motor 62 can drive the driving shaft 61 to rotate. The rotating driving shaft 61 drives the screws 63 to rotate through the bevel gears 64. The rotating screws 63 drive the two sets of horizontal fixing components 3 through threads, enabling them to move horizontally relative to each other along the slide grooves 11, realizing the function of pushing the horizontal fixing components 3 from both sides to apply positioning and clamping to the guide rail 8.

[0050] Furthermore, refer to Figure 11 and Figure 12 The cutting and recycling unit includes a cutting component 7 and a recycling component 5. The recycling component 5 includes a recycling box 51 mounted on a workbench 1, a recycling trough 52 inside the recycling box 51, a discharge pipe 53 on one side of the recycling box 51 and connected to the recycling trough 52, two sets of side boxes 54 symmetrically arranged on both sides above the recycling box 51, and two sets of guide blocks 55 symmetrically arranged inside each set of side boxes 54. The recycling box 51 has an arc-shaped structure, which can collect the fallen debris and discharge it to one side of the equipment through the discharge pipe 53. The two sets of guide blocks 55 in each set of side boxes 54 can form a funnel-shaped opening, with the larger end of the funnel located on the inner side (see reference). Figure 13 Therefore, when the cutting component 7 contacts the guide rail 8 and cuts, the cutting debris is released to one side of the recycling component 5. The metal debris that splashes to one side is guided into the side box 54 by the oblique side of the guide block 55. When the debris that enters the side box 54 bounces, it is blocked by the right-angle side of the guide block 55 and can only fall downward into the recycling tank 52. Then it is discharged to one side through the discharge pipe 53.

[0051] Among them, reference Figure 1 The cutting component 7 includes a lifting cylinder 71 vertically mounted on the workbench 1, and a horizontal beam is mounted on the top of the lifting cylinder 71. A second motor 72 is mounted on the horizontal beam, and a cutting blade 73 is connected to one side of the second motor 72. The lifting cylinder 71 can move the cutting blade 73 closer to the guide rail 8 by retracting, and the cutting blade 73 can drive the cutting blade 73 to perform a rotating cutting action.

[0052] In summary, combining Figure 14During use, the guide rail 8 is inserted from one side, so that both ends of the guide rail 8 are located within the two sets of positioning and clamping units 2. The cutting point is located below the cutting component 7. At this time, the two sets of transverse fixing components 3 of each set of positioning and clamping units 2 are located on both sides of the guide rail 8 in the horizontal direction. The drive component 6 is started to work, and the two sets of screws 63 drive their respective two sets of transverse fixing components 3 to work. Under the thread drive of the screws 63, the sliding component 31 slides along the slide groove 11 in the horizontal direction and approaches the side of the guide rail 8. During this process, the abutment block 333 and... When the pressure plate 432 touches the side of the guide rail 8, the abutment block 333 pushes the push rod 331 to move horizontally and retract into the hexagonal groove 324. The retracted push rod 331 compresses the spring 34 through the hexagonal shaft 332 to store energy. The moving push rod 331 then drives the transmission component 41 to rotate synchronously through the helical structure of the helical groove 334 and the engagement of the transmission shaft 414. The rotating transmission component 41 then drives the rack 422 through the meshing of the transmission gear 413, forcing the pressing component 42 to drive the pressing component 43 to move downward as a whole. While making lateral contact, the pressing component 43 is also subjected to the reverse force of the guide rail 8, which in turn compresses the ejector component 44 to perform retraction and energy storage. As the push rod 331 continues to move, the pressing component 42 eventually pushes the pressing component 43 to firmly abut against the lower top surface of the guide rail 8, thereby applying a vertical positioning and clamping force to the guide rail 8. After the pressing component 42 and the pressing component 43 are clamped in place, they will reverse and limit the pressing component 42 from rotating, thus preventing the push rod 331 from retracting. At this time, the abutment component 33 remains in a fixed position, while the screw... Rod 63 continues to push the sliding component 31 to move, eventually causing the abutment component 33 to firmly abut against the side of the guide rail 8. The two sets of transverse fixing components 3 move synchronously, which can apply a positioning and clamping force to the guide rail 8 from the horizontal direction. Through the cooperation of the positioning and clamping force applied by the transverse fixing component 3 in the horizontal direction and the clamping force applied by the vertical fixing component 4 in the vertical direction, a strong positioning and clamping guarantee can be provided for the guide rail 8 to be cut, effectively avoiding the phenomenon of guide rail tilting and lifting during the cutting process, ensuring the safe operation of the cutting work, and ensuring the cutting effect.

[0053] Meanwhile, the device is equipped with a set of positioning and clamping units 2 at both ends of the guide rail 8. Therefore, with the cutting point of the guide rail 8 as the center, both sides of the guide rail 8 are simultaneously clamped from the horizontal and vertical directions. Compared with the traditional method of clamping only one end, it can effectively prevent the two shorter sections of the guide rail 8 from falling or shaking after cutting, further ensuring the cutting effect and safety of use.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
