Description

Technical Field

[0001] The present invention relates to the technical field of steel cutting equipment, and particularly relates to a steel cutting device for elevator guide rail processing. Background Art

[0002] An elevator guide rail is an elevator component composed of a steel rail and a connecting plate. It is a vertical or inclined rigid rail installed in an elevator shaft or between floors, mainly used to ensure that the car and counterweight move up and down along it, and the steps of escalators and moving walks move obliquely or horizontally along it, providing guidance for the elevator car, counterweight device or steps. Its main types include T-shaped guide rails, hollow guide rails, L-shaped guide rails, C-shaped guide rails, H-shaped guide rails and sliding guide rails.

[0003] During the production of T-shaped elevator guide rails, cutting equipment is required for processing and segmenting to meet subsequent usage requirements. During the cutting process, first, the guide rail needs to be positioned to confirm the cutting position, and then cutting is performed. After the cutting is completed, the next guide rail is positioned and clamped. This cutting process has low efficiency, requires manual fixing of the guide rail position, is prone to cutting position deviation, and is not convenient for quickly adjusting according to different guide rail cutting lengths.

A ratchet pawl disc I is provided at the top of the driven bevel gear II. A reciprocating lead screw threadedly sleeved with the bottom frame is provided at the top of the ratchet pawl disc I.

[0006] Preferably, a driven bevel gear I that meshes with the active bevel gear is rotatably provided on the inner bottom surface of the mounting frame. A drive motor II for driving the active bevel gear to rotate is provided on the outer side surface of the mounting frame.

[0007] Preferably, the bottom of the driven bevel gear I is connected to a ratchet pawl disc II located below the bottom surface of the mounting frame. A transmission bevel gear is provided at the bottom end of the ratchet pawl disc II.

[0008] Preferably, a synchronous plate that does not affect the rotation of the synchronous six-sided groove is provided at the side of the bottom surface of the mounting frame. A synchronous bevel gear slidably sleeved with the synchronous six-sided groove is rotatably provided on the synchronous plate. The teeth of the synchronous bevel gear mesh with the teeth of the transmission bevel gear.

[0009] Preferably, a drive motor I for driving the transverse adjustment lead screw to rotate is provided at the end of the operating frame. A spur gear I connected to the end of the transmission shaft is provided at the bottom of the outer side surface of the operating frame. A spur gear II that is respectively in transmission meshing with the spur gear I and the tooth groove is rotatably provided on the operating frame.

[0010] Preferably, rotation limiting frames are provided at both ends of the inner side of the operating frame. A rotation groove and a limiting groove are respectively formed on the rotation limiting frames. A forward arc rack and a reverse arc rack are provided on the rotation limiting frames at corresponding positions of the two rotation grooves.

[0011] Preferably, the feeding mechanism is rotationally and slidably matched with the rotation limiting frame. The feeding mechanism includes a fixing plate connected to the rotating ring.

[0012] Preferably, a lower clamping plate is provided on one side of the bottom surface of the fixing plate. An adjusting screw is rotatably provided on the top surface of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Through the settings of the loading guard plate and the unloading guard plate, and by the mutual cooperation among the rotating ring, the loading mechanism and the conveying chain, the guide rail body can perform cyclic cutting processes such as loading, waiting, cutting, and unloading around the loading guard plate and the unloading guard plate, effectively improving the overall cutting efficiency of the equipment.

[0015] Through the setting of the transverse adjustment screw rod, and by the mutual cooperation among the reciprocating transverse movement seat, the chassis and the sawing equipment, adjustment processing can be carried out according to the cutting position of the guide rail body, facilitating the cutting operation of guide rail bodies of different lengths.

[0016] Through the setting of the bidirectional transmission mechanism, by adjusting the rotation directions of the ratchet pawl disc one and the ratchet pawl disc two, the rotation of the driving bevel gear can only drive the reciprocating screw rod or the transmission bevel gear to rotate alone, so that the driving motor two can control and adjust the height of the sawing equipment and the rotation of the rotating ring respectively, saving the capital investment in equipment manufacturing, and at the same time, when the sawing equipment cuts the guide rail body, the height of the sawing equipment can be adjusted, playing a role in synergistic efficiency improvement.

[0017] Through the setting of the rotating limit frame, according to the position matching relationship between the loading mechanism and the guide rail body, it can be determined whether the adjusting gear rotates, thereby completing the clamping and releasing operations of the guide rail body. When the guide rail body is being cut, the loading mechanism will clamp the guide rail body.

[0018] Through the settings of the forward arc rack and the reverse arc rack, the adjusting gear can be rotated forward and backward, thereby controlling the relative position height between the upper clamping plate and the lower clamping plate to adjust whether it clamps the guide rail body.

[0019] In summary, the present invention overcomes the deficiencies of the prior art. Through the feeding characteristics of the guide rail, a pipeline-type cyclic process of loading, waiting, cutting, and unloading the guide rail is carried out by means of positioning and clamping, effectively improving the overall cutting and processing efficiency, and having high social use value and application prospects.

Specific Embodiments

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: Refer to Figures 1-9, A steel cutting device for elevator guide rail processing, including an operation frame 1. An upper material protection plate 100 and a lower material protection plate 200 are respectively arranged at the lower left and upper right of the operation frame 1. A conveying chain 300 is arranged at the bottom of the operation frame 1. A conveying frame 3001 is arranged on the conveying chain 300. A heightening pad 3002 is arranged on the conveying frame 3001. A guide rail body 400 is placed and carried on the heightening pad 3002. A sliding frame 101 and a transverse adjustment screw rod 102 are arranged on the operation frame 1. The sliding frame 101 is fixedly connected to the operation frame 1. The transverse adjustment screw rod 102 is rotationally sleeved on the operation frame 1. A reciprocating transverse movement seat 1021 threadedly sleeved with the transverse adjustment screw rod 102 is slidably sleeved on the sliding frame 101. A sawing device 5 for cutting the guide rail body 400 is slidably sleeved on the reciprocating transverse movement seat 1021. The running direction of the conveying chain 300 is as Figure 2 shown, moving from right to left. When the conveying frame 3001 drives the guide rail body 400 to move to the position directly below the rotating ring 2, the conveying chain 300 stops moving until the feeding mechanism 6 can clamp the guide rail body 400. Then, with the movement of the feeding mechanism 6, the conveying chain 300 follows its movement, so that the feeding mechanism 6 can take the guide rail body 400 out of the inside of the conveying frame 3001; A transverse movement frame 105 and a transmission shaft 106 are arranged at the inner bottom of the operation frame 1. The transmission shaft 106 is rotationally sleeved on the operation frame 1. A synchronous six-sided groove 1061 is arranged in the middle section of the transmission shaft 106. A two-way transmission mechanism 7 is slidably sleeved on the transverse movement frame 105. Rotating rings 2 are respectively arranged at both ends of the operation frame 1. A feeding mechanism 6 for clamping the guide rail body 400 is arranged on the rotating ring 2. Through the setting of the two-way transmission mechanism 7, the height of the sawing device 5 can be adjusted independently, or the rotating ring 2 can be driven to rotate independently, and the operations of the two do not affect each other.

[0025] Specifically, referring to Figure 1 , Figure 5 and Figure 6 , the two-way transmission mechanism 7 includes an installation frame 701 slidably sleeved on the transverse movement frame 105. A driving bevel gear 7011 is rotatably arranged on the inner side surface of the installation frame 701. A second driven bevel gear 7014 meshing and matching with the driving bevel gear 7011 is rotatably arranged on the inner top surface of the installation frame 701. A ratchet pawl disc one 702 is arranged at the top of the second driven bevel gear 7014. A reciprocating screw rod 703 threadedly sleeved with the bottom frame 51 is arranged at the top of the ratchet pawl disc one 702. The installation frame 701 can move left and right on the transverse movement frame 105, and the transverse movement frame 105 can provide guidance and stability for the movement of the installation frame 701.

[0026] Specifically, referring to Figure 5 and Figure 6, a driven bevel gear 7013 that meshes and matches with the driving bevel gear 7011 is rotatably provided on the inner bottom surface of the mounting frame 701. A driving motor 7012 for driving the driving bevel gear 7011 to rotate is provided on the outer side surface of the mounting frame 701. The rotation speed and direction of the driving bevel gear 7011 are controlled and adjusted by the driving motor 7012.

[0027] Specifically, referring to Figure 5 and Figure 6 , a ratchet and pawl disc 704 is connected to the bottom of the driven bevel gear 7013 and is located below the bottom surface of the mounting frame 701. A transmission bevel gear 705 is provided at the bottom end of the ratchet and pawl disc 704. The driving bevel gear 7011 drives the driven bevel gear 7013 and the driven bevel gear 7014 to rotate synchronously. However, the rotation of the reciprocating lead screw 703 and the transmission bevel gear 705 is controlled by the ratchet and pawl disc 701 and the ratchet and pawl disc 704 respectively. Thus, when the driving bevel gear 7011 rotates forward, the rotation of the driven bevel gear 7013 can drive the ratchet and pawl disc 704 to rotate, the rotation of the driven bevel gear 7014 will not drive the ratchet and pawl disc 701 to rotate, and the reciprocating lead screw 703 is in a stopped state. Therefore, the ratchet and pawl disc 704 drives the transmission bevel gear 705 to rotate, thereby indirectly rotating the rotating ring 2. When the driving bevel gear 7011 rotates reversely, the driven bevel gear 7013 will not drive the ratchet and pawl disc 704 to rotate, so that the transmission bevel gear 705 is in a stopped state, while the driven bevel gear 7014 will drive the ratchet and pawl disc 701 to rotate, so that the ratchet and pawl disc 701 drives the reciprocating lead screw 703 to rotate, enabling the chassis 51 to adjust its height according to the rotation of the reciprocating lead screw 703, thereby adjusting the cutting height of the sawing device 5 to enable the sawing device 5 to perform sawing on the guide rail body 400 with different thicknesses.

[0028] Specifically, referring to Figure 5 and Figure 6 , a synchronous plate 7015 that does not affect the rotation of the synchronous hexagon groove 1061 is provided on the side of the bottom surface of the mounting frame 701. A synchronous bevel gear 7016 that is slidably sleeved with the synchronous hexagon groove 1061 is rotatably provided on the synchronous plate 7015. The teeth of the synchronous bevel gear 7016 mesh and match with the teeth of the transmission bevel gear 705. A perforation is provided on the synchronous plate 7015, and its aperture is larger than the diameter of the synchronous hexagon groove 1061. Thus, when the synchronous hexagon groove 1061 rotates, the synchronous plate 7015 will not block it. The rotation of the transmission bevel gear 705 drives the synchronous bevel gear 7016 to rotate. The synchronous bevel gear 7016 can only move horizontally left and right on the synchronous hexagon groove 1061. The rotation of the synchronous bevel gear 7016 will synchronously drive the synchronous hexagon groove 1061 to rotate, thereby rotating the transmission shaft 106.

[0029] Specifically, referring toFigure 2 , Figure 3 and Figure 6 , a driving motor 1022 for driving the lateral adjustment screw rod 102 to rotate is provided at the end of the operating frame 1. A first spur gear 103 connected to the end of the transmission shaft 106 is provided at the bottom of the outer side of the operating frame 1. A second spur gear 104 that is respectively in transmission meshing match with the first spur gear 103 and the tooth groove 21 is rotatably provided on the operating frame 1. When it is necessary to adjust the cutting position on the guide rail body 400, the driving motor 1022 can drive the lateral adjustment screw rod 102 to rotate, so that the reciprocating lateral movement seat 1021 moves left and right on the lateral adjustment screw rod 102, and the rotation of the transmission shaft 106 is transmitted to the rotating ring 2 through the first spur gear 103 and the second spur gear 104, enabling the rotating ring 2 to rotate. The rotation direction of the rotating ring 2 is as Figure 2 shown, which is a clockwise rotation, used to start clamping the guide rail body 400 from the conveying frame 3001 and perform a cyclic cutting process of loading, waiting, cutting, and unloading to improve the efficiency of the cutting process.

[0030] Example 2: Refer to Figures 1-9 . The difference between this embodiment and Embodiment 1 is that rotating limit frames 3 are provided at both ends of the inner side of the operating frame 1. Rotating grooves 301 and limiting grooves 302 are respectively formed on the rotating limit frames 3. A forward arc-shaped rack 31 and a reverse arc-shaped rack 32 are provided on the rotating limit frames 3 at corresponding positions of the two rotating grooves 301. The internal space of the rotating groove 301 is larger than the internal space of the limiting groove 302. The setting positions of the forward arc-shaped rack 31 and the reverse arc-shaped rack 32 correspond to the positions of the rotating grooves 301. The number of rotating grooves 301 is two, and the number of limiting grooves 302 is two, which are arranged oppositely.

[0031] Specifically, refer to Figure 3 , Figure 7 and Figure 9 . The loading mechanism 6 is rotationally and slidably matched with the rotating limit frame 3. The loading mechanism 6 includes a fixing plate 601 connected to the rotating ring 2. The number of the loading mechanisms 6 is four, and their numbers are respectively corresponding to the loading, waiting, cutting, and unloading processes when the device is in use.

[0032] Specifically, refer to Figure 7 and Figure 9 . One side of the bottom surface of the fixing plate 601 is provided with a lower clamping plate 602. An adjusting screw rod 603 is rotatably provided on the top surface of the fixing plate 601. A top plate 604 is threadedly sleeved on the adjusting screw rod 603. A sliding plate 605 that is movably sleeved on the top surface of the fixing plate 601 is provided at the bottom surface of the top plate 604. An upper clamping plate 606 that cooperates with the lower clamping plate 602 to clamp the guide rail body 400 is provided at the bottom end of the sliding plate 605.

[0033] Specifically, refer to Figure 7 andFigure 9 At the top of the adjusting screw 603, there are adjusting gears 607 that are respectively and individually meshed and matched with the forward arc rack 31 and the reverse arc rack 32. On the top surface of the adjusting gear 607, there is a limiting block 608 that can rotate in the rotating groove 301. In the feeding stage, the guide rail body 400 is inside the conveying frame 3001 and directly below the rotating ring 2. Then, the rotation of the rotating ring 2 drives the feeding mechanism 6 to move, so that the lower clamping plate 602 is inserted into the bottom surface of the guide rail body 400. Then, the conveying frame 3001 moves towards one end of the feeding guard plate 100 synchronously with the rotation of the rotating ring 2. At this time, the limiting block 608 enters the inside of the rotating groove 301, so that the limiting block 608 does not restrict the rotation of the adjusting gear 607. The adjusting gear 607 is meshed and matched with the forward arc rack 31, so that the top plate 604 drives the upper clamping plate 606 to move downward through the sliding plate 605, so that the upper clamping plate 606 cooperates with the lower clamping plate 602 to clamp the guide rail body 400. As the conveying frame 3001 moves, the guide rail body 400 is withdrawn from the inside of the conveying frame 3001, and the limiting block 608 will enter the inside of the limiting groove 302 accordingly, so that its rotation will be restricted, and the meshing and matching between the adjusting gear 607 and the forward arc rack 31 ends, so that the position of the upper clamping plate 606 will not change. Then, the feeding mechanism 6 clamps the guide rail body 400 to reach the waiting position. After the previous cutting process is completed, the rotating ring 2 will continue to rotate clockwise, so that the guide rail body 400 at the waiting position can enter the cutting position. The cut guide rail body 400 will be taken to the discharging position by the feeding mechanism 6. At this time, the limiting block 608 will enter the inside of the rotating groove 301, so that the adjusting gear 607 can be meshed and matched with the reverse arc rack 32, so that the feeding mechanism 6 releases the guide rail body 400, and the guide rail body 400 rolls down and is collected by the discharging guard plate 200. As the rotating ring 2 continues to rotate, the limiting block 608 will enter the inside of the limiting groove 302 again and wait to enter the rotating groove 301 next time to complete the next feeding operation.
