Description

Technical Field

[0001] This utility model relates to the field of comb plate technology, and in particular to a wire drawing device for elevator comb plates. Background Technology

[0002] Comb plates are safety protection devices for escalators and moving walkways. They are located at the entrances and exits of escalator steps and moving walkway treads, and mesh with the teeth of the steps or treads. They are transitional and safety components that facilitate passengers getting on and off the escalator. In the later stages of production, comb plates need to be brushed and polished using a wire drawing device.

[0003] When replacing the comb plate after it has been drawn into wire, the wire drawing device needs to be stopped, which affects the efficiency of wire drawing and results in low production capacity. In order to better address the above problems, promote the development of the industry's technology level, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wire drawing device for elevator comb plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire drawing device for an elevator comb plate includes a mounting plate. A second fixing frame is fixedly connected to the upper surface of the mounting plate. A wire drawing assembly is mounted on the top of the second fixing frame via a power component. A connecting shaft is movably connected to the upper surface of the mounting plate. Multiple slots are formed on the outer side of the connecting shaft. A slide is sleeved on the outer side of the connecting shaft and slides along the slots. Multiple insert rods are fixedly connected to the bottom of both sides of the slide. A fixing ring is fixedly connected to the upper surface of the mounting plate. Multiple sliding grooves are formed on both sides of the top of the fixing ring. Insert rods are inserted into the corresponding sliding grooves and slide in a sliding connection with the grooves. A support frame is fixedly connected to the top of the connecting shaft. Support plates are fixedly connected to both sides of the support frame. A clamping assembly is provided on the support plate.

[0007] As a further embodiment of this utility model, the power component includes a cylinder, which is fixed to the upper surface of the second fixed frame by bolts, and one end of the cylinder piston rod passes through the second fixed frame and is fixed to the wire drawing assembly.

[0008] As a further embodiment of this utility model, the clamping assembly includes two fixing plates, which are fixed to the bottom of the support plate by bolts. A motor is fixedly connected to one side of one of the fixing plates. A bidirectional threaded rod is movably connected between the two fixing plates, and one end of the motor output shaft is fixed to the bidirectional threaded rod.

A connecting frame is movably connected to the fixing plate, and the connecting frame is fixed to the sliding plate at the corresponding position. A clamping plate is fixedly connected to the top of the connecting frame, and the clamping plate is in contact with the upper surface of the support plate.

[0009] As a further embodiment of this invention, two guide rods are fixedly connected between the two fixed plates, and the slide plate slides along the guide rods.

[0010] As a further embodiment of this utility model, a plurality of baffles are fixedly connected to the upper surface of the support plate.

[0011] As a further embodiment of this invention, a magnetic block is fixedly connected to the top of the slot, and the slide can be attracted to and contact the magnetic block.

[0012] As a further improvement of this utility model, handles are fixedly connected to both outer walls of the slide.

[0013] As a further improvement of this utility model, a rubber pad is fixedly connected to the clamp.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the positions of the processed elevator comb plate and the unprocessed elevator comb plate are swapped by rotating the support frame. This not only facilitates the continued processing of the unprocessed elevator comb plate, but also makes it easy to remove and replace the processed elevator comb plate. This process can be repeated, saving operation time and eliminating the need to repeatedly start and stop the wire drawing assembly, thus improving the effectiveness of the device.

[0016] 2. In this utility model, a magnetic block is set to assist in fixing the slide that moves to the top of the slot, which facilitates subsequent rotation and prevents the slide from moving downwards during the rotation of the support plate, making it more stable to use.

[0017] 3. This utility model uses the clamping component and the baffle to position, clamp and restrict the elevator comb plate on the support plate, thereby enabling the elevator comb plate to be stably drawn and preventing the elevator comb plate from easily shifting during the drawing process.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0024] Reference Figures 1-4 A wire drawing device for an elevator comb plate includes a mounting plate 4, a second fixing frame 6 is fixed to the upper surface of the mounting plate 4 by bolts, and a wire drawing assembly 5 is installed on the top of the second fixing frame 6 by a power component.

[0025] The power component includes a cylinder 7, which is fixed to the upper surface of the second fixed frame 6 by bolts. One end of the piston rod of the cylinder 7 passes through the second fixed frame 6 and is fixed to the wire drawing assembly 5. The extension and retraction of the cylinder 7 drives the wire drawing assembly 5 to move up and down.

[0026] The wire drawing assembly 5 includes a mounting bracket with two sanding belt pulleys installed at the bottom, a wire drawing sanding belt wound around the two sanding belt pulleys, and a power motor that drives the sanding belt pulleys to rotate. The rotation of the power motor causes the sanding belt pulleys to move the wire drawing sanding belt, so that the wire drawing sanding belt draws the elevator comb plate.

[0027] It should be noted that a connecting shaft 16 is rotatably connected to the upper surface of the mounting plate 4. Multiple slots 19 are provided on the outer side of the connecting shaft 16. A slide 9 is sleeved on the outer side of the connecting shaft 16 and slides along the slots 19. Multiple insert rods 17 are fixed to the bottom of both sides of the slide 9 by bolts. A fixing ring 8 is fixed to the upper surface of the mounting plate 4 by bolts. Multiple sliding grooves 18 are provided on both sides of the top of the fixing ring 8. The insert rods 17 are inserted into the corresponding sliding grooves 18 and slide together with the sliding grooves 18. A magnet 15 is fixed to the top of the slot 19 by bolts. The slide 9 can be attracted to the magnet 15. The magnet 15 can assist in fixing the slide 9 that has moved to the top of the slot 19, which facilitates subsequent rotation.

[0028] A support frame 3 is bolted to the top of the connecting shaft 16. Support plates 2 are bolted to both sides of the support frame 3. Clamping components are provided on the support plates 2. Pulling the slide 9 upwards moves it upwards along the slot 19 until the slide 9 contacts the magnet 15. At the same time, the slide 9 moves upwards, causing the insertion rod 17 to move upwards and completely separate from the slide groove 18. The operator rotates the support frame 3. At this time, the connecting shaft 16 rotates, causing the slide 9 connected to its outer side to rotate with it until the positions of the clamping components at both ends of the support frame 3 are reversed. At the same time, the adjusted insertion rod 17 corresponds to the slide groove 18. The operator pushes the slide 9 downwards, causing the insertion rod 17 to be inserted into the corresponding slide groove 18, thereby fixing the position of the adjusted support plate 2. At this time, the positions of the processed elevator comb plate and the unprocessed elevator comb plate are reversed. This not only facilitates the continued processing of the unprocessed elevator comb plate, but also facilitates the removal and replacement of the processed elevator comb plate. This process can be repeated, saving operation time and eliminating the need to repeatedly start and stop the wire drawing component 5.

[0029] Specifically, the clamping assembly includes two fixing plates 13, which are bolted to the bottom of the support plate 2. One side of one of the fixing plates 13 is bolted with a motor, which is a self-locking motor, model D45D1-2430-120. A bidirectional threaded rod 10 is rotatably connected between the two fixing plates 13, and one end of the motor output shaft is fixed to the bidirectional threaded rod 10. Two sliding plates 12 are threaded to the outer side of the bidirectional threaded rod 10. A connecting frame 14 is slidably connected to the fixing plate 13, and the connecting frame 14 is fixed to the corresponding sliding plate 12. A clamping plate 20 is bolted to the top of the connecting frame 14, and the clamping plate 20 is in contact with the upper surface of the support plate 2. When the motor rotates, the bidirectional threaded rod 10 drives the two sliding plates 12 to move towards the middle, thereby moving the connecting frame 14 towards the middle until the clamping plate 20 contacts and presses the two ends of the elevator comb plate, thereby positioning and clamping the elevator comb plate.

[0030] Two guide rods 11 are bolted between the two fixed plates 13, and the slide plate 12 slides along the guide rods 11. The guide rods 11 can guide the slide plate 12 and prevent the slide plate 12 from tilting during movement. Multiple baffles 1 are bolted to the upper surface of the support plate 2. The two elevator comb plates that need to be wire drawn are placed on the support plate 2 respectively, and one side of the elevator comb plate is in contact with the baffle 1. Pull handles are bolted to both outer walls of the slide 9 to facilitate the movement of the slide 9. Rubber pads are glued to the clamp plate 20.

[0031] Working principle: When it is necessary to draw the elevator comb plates, firstly, place the two elevator comb plates to be drawn on the support plate 2 respectively, and make one side of the elevator comb plate contact the baffle 1. Then start the motor. The motor rotation causes the bidirectional threaded rod 10 to drive the two slide plates 12 to move towards the middle respectively, thereby causing the connecting frame 14 to move towards the middle until the clamping plate 20 contacts and squeezes the two ends of the elevator comb plate, thereby positioning and clamping the elevator comb plate. Then, draw the elevator comb plate located at the bottom of the drawing assembly 5 first, that is, start the drawing assembly 5, so that the sanding belt pulley drives the drawing sanding belt to move. Start the cylinder 7, the cylinder 7 extends and moves the drawing assembly 5 downward, so that the drawing sanding belt draws the surface of the elevator comb plate. After the wire drawing is completed, when it is necessary to replace another elevator comb plate, pull the slide 9 upward to move it upward along the slot 19 until the slide 9 contacts the magnet 15. At the same time, the upward movement of the slide 9 causes the insert rod 17 to move upward and completely separate from the slide groove 18. The operator rotates the support frame 3. At this time, the connecting shaft 16 rotates, causing the slide 9 connected to the outside to rotate with it until the positions of the support plates 2 at both ends of the support frame 3 are reversed. At this time, the insert rod 17 corresponds to the slide groove 18 at the corresponding position. The operator pushes the slide 9 downward to insert the insert rod 17 into the slide groove 18 at the corresponding position, thereby fixing the position of the adjusted support plate 2. Then, the operator uses the wire drawing assembly 5 to draw the elevator comb plate.
