Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to a device for cutting and recovering scraps of elevator guide rails. Background Art

[0002] Elevator guide rails are a type of metal structure that provides guidance for the car and counterweight when the elevator is running, as well as support when the safety clamp is braked. After the elevator has been used for a long time, the guide rails need to be repaired and replaced. At the same time, in order to ensure the reuse of resources, the elevator guide rails need to be cut and recycled.

[0003] The elevator guide rails in the prior art are mostly in the form of T-shaped structures and L-shaped structures. When performing cutting operations, in order to ensure the cutting effect, it is often necessary to clamp these guide rails with peculiar structures in place by means of clamps. The clamps used in the prior art often position and clamp the guide rails in the horizontal direction (i.e., apply limiting force to the guide rails from both sides). Therefore, under the action of the downward stress of the blade during the cutting process, the guide rails are prone to offset and warping. The deflection phenomenon will cause cutting misalignment, thereby affecting the cutting effect. The warping phenomenon is centered on the cutting point. The cutting point is subjected to the downward stress of the blade, which will cause the ends of the guide rails on both sides of the cutting point to warp upwards. The upwardly warped guide rails on both sides will abut and squeeze the two sides of the cutting blade, thereby causing the cutting blade to be stuck, seriously affecting the safe implementation of the cutting work and posing a major safety hazard.

Detailed implementation manners

[0031] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0032] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] Referring to Figures 1 to 14 , which is an embodiment of the present invention, includes an elevator guide rail corner waste cutting and recycling device, including a workbench 1, two groups 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 groups of positioning and clamping units 2. The positioning and clamping unit 2 is composed of two groups of symmetrically arranged lateral fixing members 3 and two groups of symmetrically arranged vertical fixing members 4, and each group of vertical fixing members 4 is correspondingly arranged on each group of lateral fixing members 3; Referring to Figure 14, the horizontal fixing member 3 can apply a positioning clamping force in the horizontal direction, while the vertical fixing member 4 can apply a positioning clamping force in the vertical direction. The symmetric arrangement of the horizontal fixing members 3 enables them to apply clamping forces inward from both sides simultaneously. The method of clamping inward from both sides can center and align the guide rail 8 located between the two sets of horizontal fixing members 3, avoiding the formation of an inclined clamping state and eliminating the phenomenon of clamping deviation. The two sets of vertical fixing members 4 in a symmetric posture can also apply a positioning clamping force in the vertical direction to the guide rail 8 from both sides; The horizontal fixing member 3 includes a sliding component 31 slidably connected to the workbench 1, a fixing component 32 horizontally arranged at the top of the sliding component 31, and an abutting component 33 horizontally inserted on one side of the fixing component 32. The abutting component 33 includes two sets of symmetrically arranged push rods 331, a hexagonal shaft 332 arranged at one end of the push rod 331 and having a hexagonal prism structure, an abutting block 333 horizontally arranged at the other end of the push rod 331, and spiral grooves 334 opened on the outer wall of each set of push rods 331, and the spiral grooves 334 are in a spiral structure; Refer to Figure 3 And Figure 4 , as the part that first contacts the guide rail 8, the abutting component 33 can abut and clamp the guide rail 8 from the side. The spiral grooves 334 with a spiral structure are evenly wound around the push rod 331, and there are two sets of spiral grooves 334. The two sets of spiral grooves 334 are annularly equally divided and wound around the push rod 331 with the axis of the push rod 331 as the midpoint; The vertical fixing member 4 includes two sets of transmission components 41 symmetrically and rotatably arranged 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 at 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 arranged on the inner wall of the transmission component 41, and the outer end of the transmission shaft 414 extends into the spiral groove 334. The pressing component 42 is vertically slidably inserted on the side of the fixing component 32, and racks 422 meshing with the transmission gear 413 are opened on both sides of the pressing component 42; Refer to Figure 4 And Figure 7, the 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 drive the transmission component 41 to rotate to release the pressure. The rotating transmission component 41 then drives the entire pressing component 42 to slide vertically on the side of the fixed component 32 through the engagement of the external transmission gear 413 and the rack 422, thereby realizing the function of applying a positioning clamping force in the vertical direction.

[0034] Among them, referring to Figure 9 and Figure 10 , two sets of sliding grooves 11 are parallelly opened on the workbench 1, 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 arranged at the end of the sliding frame 311, limit blocks 313 arranged on both sides of the sliding frame 311, and a relief groove 314 opened inside 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 limit blocks 313. At the same time, it is limited by the sliding groove 11 and can translate horizontally along the sliding groove 11. The relief groove 314 is used to avoid and accommodate the ejecting component 44.

[0035] Among them, referring to Figure 3 and Figure 6 , the fixed component 32 includes a mounting block 321 fixedly arranged at the top of the sliding frame 311, limit rings 322 symmetrically arranged on one side of the mounting block 321, and the transmission component 41 is inserted on the limit rings 322. A T-shaped groove 323 is opened between the two limit rings 322, and the side of the pressing component 42 is vertically inserted into the T-shaped groove 323. A hexagonal groove 324 is opened inside both sides of the mounting block 321, and the push rod 331 extends into the hexagonal groove 324. At the same time, the shape of the hexagonal groove 324 matches that of the hexagonal shaft 332. A first spring 34 is arranged in the hexagonal groove 324. The limit rings 322 are used to limit the transmission component 41 so that the transmission component 41 cannot be separated from the limit rings 322, but can rotate around its own axis within the limit rings 322. The hexagonal groove 324 can limit the hexagonal shaft 332 through a structure matching the hexagonal shaft 332, so that the hexagonal shaft 332 can only translate horizontally along the hexagonal groove 324, thereby limiting the push rod 331 fixedly connected to the hexagonal shaft 332 from rotating. The first spring 34 supports through its own elasticity and pushes out the hexagonal shaft 332 outward, so that the push rod 331 is always in a state of extending out of the hexagonal groove 324, that is, the entire abutting component 33 is always in an outward extending state.

[0036] Among them, refer to Figure 3 and Figure 7 The transmission assembly 41 includes a sleeve 411 inserted into the limiting ring 322, and a baffle 412 fixedly arranged at one end of the sleeve 411, and 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 through the limiting of the baffle 412, it can maintain constant connection with the limiting ring 322 and will not fall off.

[0037] Further, see 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 vertically slidably inserted into the T-shaped slot 323. The T-shaped slider 423 cooperates with the T-shaped slot 323 to enable the pressing component 42 to move vertically only on the side of the fixed component 32.

[0038] Among them, refer to Figure 7 The pressing assembly 43 includes a horizontal plate 431 inserted into the bottom end of the pressing assembly 42, a pressing plate 432 transversely arranged at the outer end of the horizontal plate 431, and a slot 433 opened inside the pressing plate 432. The horizontal plate 431 enables the pressing assembly 43 to move horizontally at the bottom of the transmission assembly 41. The pressing plate 432 is 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.

[0039] Further, see Figure 5 and Figure 7 The vertical fixing component 4 also includes an ejection assembly 44 arranged in the slot 433, and the ejection assembly 44 includes a push rod 441 arranged between the cross plate 431 and the sliding assembly 31, and one end of the push rod 441 extends into the slot 433, and a spring 2 442 is arranged at one end of the push rod 441, and the spring 2 442 is located in the slot 433 as a whole. The rack 422 pushes the push rod 441 out and extends it into the give way groove 314 through elastic support. The overall function of the ejection assembly 44 is to always push the pressing assembly 43 as a whole outward, so that the pressing plate 432 is parallel to the bottom of the stop block 333, and the outer ends of the two are on the same vertical line, ensuring that the two can contact the guide rail 8 simultaneously and accurately, avoiding the problem of inadequate clamping and inaccurate clamping.

[0040] Among them, refer to Figure 9 and Figure 10, a driving component 6 is arranged at the bottom of the workbench 1. The driving component 6 includes a horizontally arranged driving shaft 61, a first motor 62 connected to one end of the driving shaft 61, two screw rods 63 correspondingly arranged below two sliding grooves 11, and the end of the sliding assembly 31 is in threaded connection with the screw rod 63. Two bevel gears 64 are arranged on the driving shaft 61 and correspond to the positions of the screw rods 63. A bevel gear 65 is arranged at one end of the screw rod 63 and meshes with the bevel gear 64. The driving shaft 61 is rotatably arranged on the workbench 1. The first motor 62 can drive the driving shaft 61 to rotate. The rotating driving shaft 61 drives the screw rod 63 to rotate through the bevel gear 64. The rotating screw rod 63 drives the two horizontally fixed components 3 through the thread, enabling them to perform relative movement in the horizontal direction along the sliding grooves 11, so as to realize the function of pushing the horizontally fixed components 3 from both sides to apply positioning and clamping to the guide rail 8.

[0041] Further, referring to Figure 11 With 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 arranged on the workbench 1, a recycling groove 52 opened inside the recycling box 51, a discharge pipe 53 arranged on one side of the recycling box 51, and the discharge pipe 53 is communicated with the recycling groove 52. Two side boxes 54 are symmetrically arranged on both sides above the recycling box 51, and two guide blocks 55 are symmetrically arranged inside each side box 54. The recycling box 51 is in an arc structure, which can collect the fallen debris and discharge it to one side of the equipment through the discharge pipe 53. The two guide blocks 55 in each side box 54 can form a notch with a flared opening, and the larger end of the flared opening is located inside (refer to Figure 13 ). Therefore, when the cutting component 7 contacts the guide rail 8 and performs cutting, the debris generated by cutting is released to one side of the recycling component 5. The metal debris splashing to one side will enter the side box 54 through the guiding of the inclined side of the guide block 55. When the debris entering the side box 54 rebounds, it will be blocked by the right-angled side of the guide block 55 and can only fall downward into the recycling groove 52, and then be discharged to one side through the discharge pipe 53 together.

[0042] Among them, referring to Figure 1 , the cutting component 7 includes a lifting cylinder 71 vertically arranged on the workbench 1. A cross beam is horizontally erected at the top end of the lifting cylinder 71. A second motor 72 is arranged on the cross beam, and a cutting blade 73 is connected to one side of the second motor 72. The lifting cylinder 71 can drive the cutting blade 73 to approach the guide rail 8 by contraction, and the cutting blade 73 can drive the cutting blade 73 to perform a rotating cutting action.

[0043] In summary, in combination with Figure 14During use of the device, the guide rail 8 is passed from one side so that the two ends of the guide rail 8 are located in the two groups of positioning and clamping units 2, and the point to be cut is located below the cutting component 7. At this time, the two groups of transverse fixing components 3 of each group of positioning and clamping units 2 are respectively located on both sides of the guide rail 8 in the horizontal direction. The driving component 6 is started to work, and the two groups of screw rods 63 respectively drive the two corresponding groups of transverse fixing components 3 to work. The sliding component 31 slides horizontally along the slide groove 11 under the thread drive of the screw rod 63 to approach the side of the guide rail 8. In this process, the stop block 333 and The pressing plate 432 touches the side of the guide rail 8, and the stop 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 cooperates with the transmission shaft 414 through the spiral structure of the spiral groove 334 to synchronously drive the transmission assembly 41 to rotate. The rotating transmission assembly 41 engages with the transmission gear 413 to push the rack 422, forcing the pressing assembly 42 to drive the pressing assembly 43 to move downward as a whole. At the same time as the side contact, the pressing assembly 43 will also be subjected to the reverse force of the guide rail 8, thereby compressing the ejection assembly 44 to perform contraction and energy storage work. As the push rod 331 continues to move, the pressing assembly 42 will eventually push the pressing assembly 43 to abut firmly against the top surface of the lower end of the guide rail 8, thereby applying a positioning clamping force from the vertical direction to the guide rail 8. After the pressing assembly 42 and the pressing assembly 43 are clamped in place, the pressing assembly 42 will be reversely limited and cannot rotate, thereby making the push rod 331 unable to contract. At this time, the abutting assembly 33 as a whole maintains a fixed posture, and the screw The rod 63 continues to push the sliding assembly 31 to move, and finally makes the abutment assembly 33 firmly abut against the side of the guide rail 8. The two sets of horizontal fixing components 3 move synchronously, and 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 in the horizontal direction by the horizontal fixing component 3 and the clamping force applied in the vertical direction by the vertical fixing component 4, a strong positioning and clamping guarantee can be provided for the guide rail 8 to be cut, effectively avoiding the guide rail from deflecting and warping during the cutting process, ensuring the safe implementation of the cutting work and ensuring the effect of the cutting work. At the same time, the device is provided with a group of positioning clamping units 2 at both ends of the guide rail 8. Therefore, with the point to be cut of the guide rail 8 as the center, both sides of the guide rail 8 are synchronously applied with positioning clamping from the horizontal direction and the vertical direction. Compared with the traditional technology of clamping only one end, it can effectively avoid the two shorter guide rails 8 from falling or shaking after cutting, thereby further ensuring the cutting effect and safety of use.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
