Description

Technical Field

[0002] The elevator guide rail assembly is a very important part of the elevator system, responsible for guiding the up and down movement of the elevator car and counterweight to ensure its stable operation. The elevator guide rail assembly mainly consists of guide rails, guide rail brackets and guide shoes.

[0003] In the elevator guide rail assembly, the angle iron in the guide rail bracket is used to fix the guide rail on the building. During its processing, usually a long steel bar is bent into shape, and then punching is performed on its surface at a predetermined interval to form mounting holes, and then the whole section is cut to form a rough blank of the angle iron.

[0004] At present, there are the following defects in the automatic cutting of the angle iron on the guide rail bracket: 1. After the long steel bar is bent into an L-shaped steel bar, punching and cutting and whole-section cutting are carried out on different devices successively. The steel bar needs to be loaded and unloaded for each step, and a large amount of time is wasted when transferring from the previous step to the next step, and the efficiency needs to be improved; 2. During continuous whole-section cutting, the steel bar is generally conveyed by conveying rollers at the same time. When cutting at a designated position, since the lower part of the steel bar is supported by the conveying rollers, it is difficult for a conventional positioning device to effectively position the steel bar, thus affecting the cutting quality of the steel bar.

The angle iron steel 24 bent into an L-shaped structure is placed on the conveying mechanism 2, and then one end of the angle iron steel 24 passes through the straightening mechanism 4, so that the angle iron steel 24 can be stably conveyed on the conveying mechanism 2, and when conveyed to the position of the punching mechanism 3, the first sliding mechanism 5 and the second sliding mechanism 7 cooperate with their respective fixing mechanisms 8 to further position and fix the angle iron steel 24, and then the punching mechanism 3 and the laser cutter 10 are used to punch and cut.

[0035] See also Figure 1 and Figure 8 The conveying mechanism 2 includes a plurality of conveying rollers 201 rotatably arranged at the rear side of the upper part of the frame 1 and a plurality of guide rollers 202 rotatably arranged at the front side of the upper part of the frame 1. Any common end of two adjacent conveying rollers 201 is connected by a first pulley group. A first motor 203 is fixedly arranged on the right side of the upper part of the frame 1. The output shaft of the first motor 203 is fixedly connected to the right end of the frontmost conveying roller 201. The conveying rollers 201 are driven to rotate by the first motor 203, so that all conveying rollers 201 rotate synchronously to convey the angle iron steel 24. When the angle iron steel 24 is conveyed to the vicinity of the punching mechanism 3, the guide rollers 202 support the angle iron steel 24.

[0036] See also Figure 1 , Figure 4 , Figure 8 and Figure 9, the alignment mechanism 4 includes two front and rear slide rails 401 fixedly arranged on the upper part of the cross plate 6. A screw rod 402 is rotatably arranged on the upper part of the slide rail 401. The screw rod 402 is provided with two thread segments with opposite thread directions, and two sliders 403 are threadedly connected to both thread segments. A first limiting plate 404 is fixedly connected between the two left sliders 403. Adjusting components 405 are arranged on both right sliders 403. A second limiting plate 406 with an L-shaped structure is commonly connected to the two adjusting components 405. A plurality of limiting rollers 407 arranged left and right are rotatably arranged on the vertical section and the horizontal section of the second limiting plate 406 and the side wall of the first limiting plate 404. The right ends of the two screw rods 402 are commonly connected by a sprocket group. A second motor 408 is fixedly arranged at the left end of any one of the slide rails 401, and the output shaft of the second motor 408 is fixedly connected to the left end of the corresponding screw rod 402. The adjusting component 405 includes a first connecting column 4051 with the lower end fixedly connected to the corresponding right slider 403. A second connecting column 4052 is threadedly connected to the upper end of the first connecting column 4051. The upper end of the second connecting column 4052 is rotatably connected to an L-shaped third connecting column 4053, and the third connecting column 4053 is fixedly connected to the second limiting plate 406.

[0037] To facilitate the stable feeding of the angle steel 24, the screw rod 402 is driven to rotate by the second motor 408, so that the left and right sliders 403 can approach or move away from each other, so that the first limiting plate 404 and the second limiting plate 406 can approach or move away from each other to adjust the distance, ensuring that the limiting rollers 407 on the first limiting plate 404 and the limiting rollers 407 on the vertical section of the second limiting plate 406 can respectively abut against the left and right side walls of the vertical section of the angle steel 24. And at the same time, rotate the two second connecting columns 4052 before and after, so that the distance between the first connecting column 4051 and the third connecting column 4053 changes, so that the height of the second limiting plate 406 changes, so that the limiting rollers 407 on the horizontal section of the second limiting plate 406 can abut against the upper part of the horizontal section of the angle steel 24, so as to position the angle steel 24 on the frame 1 in a predetermined posture and convey it through the conveying mechanism 2.

[0038] Refer to Figure 1 、 Figure 5 、 Figure 7 and Figure 10, the punching mechanism 3 includes a mounting plate 301 which is fixedly arranged on the upper right side of the frame 1 and has an L-shaped structure. Hydraulic rods 302 are fixedly arranged on the left side of the vertical section and the upper part of the horizontal section of the mounting plate 301. The output shafts of the hydraulic rods 302 are fixedly connected with two punching cutters 303 which are symmetrically arranged front and back. On the front and back sides of the mounting plate 301 on the upper right side of the frame 1, push rods 25 are fixedly arranged. The left end of the push rod 25 has a frustum structure. An activity hole 3031 is opened at the central position inside the punching cutter 303, and the activity hole 3031 and the corresponding push rod 25 are concentrically arranged. On the upper part of the cross plate 6 and below the punching cutter 303, an inclined material receiving plate 26 is fixedly arranged.

[0039] In order to facilitate the discharge of the waste material after punching, after the angle steel 24 is positioned by the fixing mechanism 8, the corresponding punching cutter 303 is driven by the hydraulic rod 302 on the right side of the frame 1 to move towards the surface of the vertical section of the angle steel 24 and finally contact it. The punching cutter 303 can cut off the corresponding part on the angle steel 24. The waste material of the cut-off part is retained inside the punching cutter 303. Then the hydraulic rod 302 on the right side contracts, driving the punching cutter 303 to reset. During the reset process of the punching cutter 303, the activity hole 3031 at its central position will be inserted with the corresponding push rod 25, so that the push rod 25 is inserted into the punching cutter 303. And with the movement of the punching cutter 303, the push rod 25 can push out the waste material inside the punching cutter 303. After the waste material is pushed out, it falls on the lower material receiving plate 26 and is discharged. Then the hydraulic rod 302 above the center of the frame 1 acts, driving the corresponding punching cutter 303 to move towards the surface of the horizontal section of the angle steel 24 and finally contact it. The punching cutter 303 can cut off the corresponding part on the angle steel 24, and the cut waste material automatically falls on the lower material receiving plate 26 and is discharged under the action of gravity.

[0040] Refer to Figure 1 , Figure 4 , Figure 11 and Figure 12 , the fixing mechanism 8 includes a connecting frame 801 with a U-shaped structure. Positioning components 802 and a support seat 803 are respectively fixedly arranged at the front and rear pin ends of the connecting frame 801. The positioning component 802 includes a connecting plate 8021 fixedly connected with the pin end of the connecting frame 801. On the side of the connecting plate 8021 close to the angle steel 24, two symmetrically arranged front and back sleeves 8022 are fixedly arranged. A first spring 8023 is fixedly arranged inside the sleeve 8022. One end of the first spring 8023 close to the port of the sleeve 8022 is fixedly connected with a positioning column 8024 which matches the end face of the punching cutter 303. The positioning column 8024 is slidably arranged inside the sleeve 8022. Through holes 8031 which are symmetrically arranged front and back and match the end face of the punching cutter 303 are opened on the surface of the support seat 803. A limiting bar 11 is fixedly arranged on the front side of the connecting frame 801 close to the second sliding mechanism 7.

[0041] In order to improve the stability of the angle steel 24 during processing, the angle steel 24 moves towards the limit stop bar 11 through the conveying mechanism 2 and makes contact. At this time, the angle steel 24 is in place. Then, the driving mechanism 9 drives the first sliding mechanism 5 and the second sliding mechanism 7 to act, so that the fixing mechanisms 8 on the first sliding mechanism 5 and the second sliding mechanism 7 can move towards the angle steel 24. The two positioning posts 8024 on the fixing mechanism 8 can be inserted into the two mounting holes that have been opened on the side wall of the angle steel 24. After the four positioning posts 8024 on the two fixing mechanisms 8 are inserted into the corresponding mounting holes at the same time, the angle steel 24 can be positioned in the front-rear direction, and the support seats 803 on the fixing mechanism 8 can also be synchronously attached to the preset punching positions on the surface of the angle steel 24. When the punching tool 303 on the punching mechanism 3 moves to this position, the support seat 803 can support the angle steel 24 from the other side of the angle steel 24 to improve the punching quality.

[0042] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown in FIGS.

[0043] The driving mechanism 9 drives the first worm and worm gear set 504 to rotate, enabling the first rotating shaft 502 to drive the two first gears 503 to rotate. The rotation of the two first gears 503 drives the corresponding first toothed plates 501 to move. The movement of the first toothed plates 501 drives the fixing mechanism 8 located on the left side of the angle steel 24 to contact and position with the angle steel 24. At the same time, after the first toothed plate 501 moves in place, at this time the first chute is aligned with the first limiting block 13, and the first through electromagnet 12 is energized to adsorb the first limiting block 13 to move into the first chute, so that the first limiting block 13 is inserted into the first chute to limit and lock the first toothed plate 501. When the punching mechanism 3 exerts pressure on the support seat 803, the first toothed plate 501 will receive a thrust from the support seat 801. Since the first toothed plate 501 is locked, it will not move at this time. After that, when the first toothed plate 501 needs to move, the first through electromagnet 12 is de-energized, so that the first limiting block 13 is reset under the action of the second spring 15 to release the limit on the first toothed plate 501.

[0044] Refer to Figure 2 and Figure 7 , the driving mechanism 9 includes a third motor 901 fixedly arranged on the front side of the frame 1. The third motor 901 is set as a double-shaft motor, and the left output shaft of the third motor 901 and the worm in the first worm and worm gear set 504 are commonly connected by a second pulley set 902 for transmission. The third motor 901 rotates forward and cooperates with the second pulley set 902 to drive the first worm and worm gear set 504 to work and drive the first rotating shaft 502 to rotate.

[0045] Refer to Figure 1 , Figure 5 , Figure 6 and Figure 7, the second sliding mechanism 7 includes a vertical plate 701 fixedly arranged on the cross plate 6. A second rotating shaft 702 is rotatably arranged on the vertical plate 701. A second gear 703 is fixedly arranged at the rear end of the second rotating shaft 702. A second toothed plate 706 is engaged with the second gear 703. The second toothed plate 706 is fixedly connected to the horizontal section of the corresponding connecting frame 801. Guide columns 704 are fixedly arranged on both the front and rear sides of the upper part of the cross plate 6 where the second toothed plate 706 is located. The guide columns 704 are slidably connected to the horizontal section of the corresponding connecting frame 801. A second worm and gear set 705 is arranged at the front end of the second rotating shaft 702. The right output shaft of the third motor 901 is fixedly connected to the worm in the second worm and gear set 705. A guide groove is formed on the left side wall of the second toothed plate 706. A guide plate 16 is slidably connected in the guide groove. The lower end of the guide plate 16 is fixedly connected to the upper part of the cross plate 6. A second sliding groove is formed inside the front side of the guide plate 16 near the lower part. A third spring 17 is fixedly arranged in the second sliding groove. One end of the third spring 17 close to the port of the second sliding groove is fixedly connected to an iron second limiting block 18. The second limiting block 18 is slidably arranged in the second sliding groove. The second limiting block 18 is in movable contact with the lower surface of the second toothed plate 706. An activity cavity communicating with the second sliding groove is formed inside the guide plate 16. A second through electromagnet 19 is fixedly arranged in the activity cavity.

[0046] By driving the second worm and gear set 705 to act through the forward rotation of the third motor 901, the second rotating shaft 702 rotates, driving the second gear 703 to rotate, so that the second toothed plate 706 drives the corresponding fixing mechanism 8 to move towards the angle steel 24 and contact for positioning. At the same time, after the second toothed plate 706 moves in place, the second through electromagnet 19 is powered off, so that the originally compressed third spring 17 loses pressure and resets, driving the second limiting block 18 to move out of the second sliding groove. The upper part of the second limiting block 18 abuts against the lower part of the second toothed plate 706, and the second toothed plate 706 is limited and locked by the second limiting block 18.

[0047] Refer to Figure 5 , a guide seat 20 is fixedly arranged at the right side of the frame 1 near the second toothed plate 706. A third toothed plate 21 is movably arranged in the guide seat 20. The upper part of the third toothed plate 21 is fixedly connected to the laser cutter 10. A third rotating shaft 22 is rotatably arranged on the vertical plate 701. A third gear 23 is fixedly arranged at the rear end of the third rotating shaft 22. The third gear 23 is engaged with both the second gear 703 and the third toothed plate 21.

[0048] In order to improve the cutting efficiency of angle steel 24, after the two fixing mechanisms 8 fix the angle steel 24, the hydraulic rod 302 on the right side of the frame 1 drives the blanking tool 303 to blank the angle steel 24 and reset. Then, the hydraulic rod 302 above the center of the frame 1 drives the blanking tool 303 to blank the angle steel 24 again. At this time, the two blanking tools 303 are inserted into the side wall of the horizontal section of the angle steel 24 to position the angle steel 24. Then, the third motor 901 rotates in reverse, so that the first sliding mechanism 5 and the second sliding mechanism 7 drive their respective fixing mechanisms 8 to reset at the same time. Meanwhile, the third rotating shaft 22 rotates synchronously, driving the third gear 23 to rotate, driving the third toothed plate 21 to move downward. During the downward movement of the third toothed plate 21, the laser cutter 10 at its upper end works to cut the angle steel 24. After the cutting is completed, the hydraulic rod 302 above the center of the frame 1 resets, resetting the two blanking tools 303 originally inserted into the side wall of the horizontal section of the angle steel 24, so that the angle steel 24 is released from the limit, and is continuously conveyed and processed through the conveying mechanism 2.

[0049] Refer to Figure 1-Figure 12 , specifically during operation, first perform pre-treatment on the angle steel 24: put a long section of the formed angle steel 24 into the conveying mechanism 2 from the rear end of the frame 1. At the same time, the angle steel 24 is limited and guided by the first limit plate 404 and the second limit plate 406 of the alignment mechanism 4. The angle steel 24 moves towards the position of the limit stop bar 11 under the drive of the conveying mechanism 2 until the front side of the angle steel 24 abuts against the limit stop bar 11 and then stops moving. The drive mechanism 9 cooperates with the first sliding mechanism 5 and the second sliding mechanism 7 to act, driving the fixing mechanism 8 to move towards the angle steel 24. Since no mounting holes are opened on the surface of the angle steel 24, after the positioning column 8024 abuts against the surface of the angle steel 24, it will be compressed and enter the sleeve 8022. Then, the hydraulic rod 302 on the left side of the frame 1 drives the corresponding two blanking tools 303 to punch holes in the angle steel 24. Then, the hydraulic rod 302 above the center first drives the two blanking tools 303 to cut out two mounting holes in the lower part of the angle steel 24. At this time, the blanking tools 303 do not reset and are inserted into the side wall of the horizontal section of the angle steel 24. Then, the drive mechanism 9 drives the first sliding mechanism 5 and the second sliding mechanism 7 to move in the reverse direction, so that the fixing mechanism 8 is separated from the angle steel 24. The third rotating shaft 22 synchronously follows the second rotating shaft 702 to rotate, and the third gear 23 drives the third toothed plate 21 to move downward. During the downward movement of the third toothed plate 21, the laser cutter 10 at its upper end works to cut the angle steel 24. Then, the two blanking tools 303 originally inserted into the horizontal section of the angle steel 24 are reset. At this time, four initial mounting holes are cut out on the angle steel 24, completing the pre-treatment of the angle steel 24.

[0050] Automatic continuous punching and cutting and whole-section cutting: The conveying mechanism 2 drives the angle iron steel 24 to continue to move, and the main body of the angle iron steel 24 moves toward the direction of the limit stop bar 11. At this time, the limit stop bar 11 is below the horizontal section of the angle iron steel 24. During the movement of the angle iron steel 24, the cut part will move with the movement of the main body of the angle iron steel 24 until the main body of the angle iron steel 24 is close to the limit stop bar 11 for a certain distance. The cut part will automatically fall off the guide roller 202, and then the limit stop bar 11 will be reset. The main body of the angle iron steel 24 continues to move toward the limit stop bar 11 and finally conflicts with the limit stop bar 11. At this time, the driving mechanism 9 cooperates with the first sliding mechanism 5 and the second sliding mechanism 7 to control the corresponding fixing mechanism 8 to move toward the main body of the angle iron steel 24 again, and finally the positioning column 8024 on the fixing mechanism 8 is inserted into the pre-closed mounting hole on the main body of the angle iron steel 24, so as to position the main body of the angle iron steel 24. , and then the vertical section and horizontal section of the main body of the angle iron steel 24 are punched in turn by the punching mechanism 3. After the punching of the horizontal section of the main body of the angle iron steel 24 is completed, the two punching tools 303 remain inserted in the angle iron steel 24, and then the fixing mechanism 8 is reset and no longer positions the angle iron steel 24. At the same time, the limit stop bar 11 moves again to the bottom of the horizontal section of the angle iron steel 24, and will not hinder its movement. During the reset process, the laser cutter 10 cuts the angle iron steel 24 from top to bottom. At this time, the two punching tools 303 are used to position the main body of the angle iron steel 24 to ensure the cutting quality. The cut part is the angle iron blank. Then the two punching tools 303 originally inserted in the main body of the angle iron steel 24 are reset. At this time, the main body of the angle iron steel 24 is released from the limit and continues to move through the conveying mechanism 2. The cut angle iron blank falls from the guide roller 202, and this cycle is repeated to process the next angle iron blank.
