Description

Technical Field

[0001] This utility model relates to the field of comb plate technology, and in particular to a comb plate protection device. Background Technology

[0002] Comb plates are located at the entrances and exits of running steps or treads, facilitating passenger transition and engaging with steps, treads, or conveyor belts. Traditionally, comb plates are transported by placing them directly on a trolley and stacking them. However, when comb plates are stacked, external factors can easily cause damage to the comb teeth or surface, affecting their normal use and service life.

[0003] To better address the aforementioned issues, protect the comb plate from damage, promote the development of industry technology, and enhance core competitiveness, this application proposes a new compositional structure that differs from existing technologies. Utility Model Content

[0021] 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.

[0022] Reference Figures 1-3 A comb plate protection device includes a housing 1. Multiple sliding grooves 17 are provided on both sides of the housing 1. A limiting plate 5 and a connecting plate 14 are slidably connected inside the housing 1 through the sliding grooves 17. A through groove is provided on the back of the housing 1. The protruding parts on one side of the limiting plate 5 and the connecting plate 14 pass through the through groove.

[0023] A fixing frame 7 is fixed to the bottom outer wall of the housing 1 by bolts. A mounting plate 12 is fixed to one side of the fixing frame 7 and one side of the outer wall of the housing 1 by bolts. A threaded rod 11 is rotatably connected between the two mounting plates 12. The threaded rod 11 has a trapezoidal thread structure. The limiting plate 5 is threadedly connected to the threaded rod 11. The connecting plate 14 is gap-connected to the threaded rod 11.

[0024] Two limiting blocks 20 are fixed to one side of the outer wall of the housing 1 by bolts, and the limiting blocks 20 are in contact with the bottom of the connecting plate 14. The limiting blocks 20 can support the initial position of the connecting plate 14.

[0025] The threaded rod 11 has a nut 10 threadedly connected to the portion of its tip that passes through the mounting plate 12. The nut 10 is in pressing contact with the mounting plate 12. Rotating the nut 10 causes it to press against the adjacent mounting plate 12, thereby further restricting the position of the rotated threaded rod 11.

[0026] A guide rod 13 is fixed between the two mounting plates 12 by bolts, and the guide rod 13 is slidably connected to the connecting plate 14 and the limiting plate 5. The guide rod 13 can guide the connecting plate 14 and the limiting plate 5, so that they can move up and down stably and avoid tilting during the movement.

[0027] In particular, rubber frames 4 are bonded to the upper surfaces of the limiting plate 5 and the connecting plate 14. A partition 16 is fixed to the middle position of the rubber frame 4 by bolts. The partition 16 divides the rubber frame 4 into two identical spaces, and multiple comb plates are placed into the two spaces on the limiting plate 5 and the connecting plate 14 separated by the partition 16.

[0028] Multiple connecting posts 2 are fixed to the top inner wall of the shell 1 by bolts, and a fixing plate 3 is fixed between the bottom ends of the multiple connecting posts 2 by bolts. The bottom of the fixing plate 3 and the connecting plate 14 are both fixed with two convex plates 15 by bolts.

[0029] Then rotate the threaded rod 11 to move the limiting plate 5 upward, causing the comb plate inside the rubber frame 4 to move upward until the convex plate 15 at the bottom of the connecting plate 14 contacts the comb plate on the limiting plate 5. Then the threaded rod 11 continues to move the limiting plate 5 upward, causing the comb plate on the limiting plate 5 to push the connecting plate 14. At this time, the connecting plate 14 moves the comb plate placed inside it upward, causing the connecting plate 14 to separate from the limiting block 20, until the comb plate on the connecting plate 14 contacts the convex plate 15 at the bottom of the fixed plate 3, thereby positioning and protecting the comb plate.

[0030] It should be noted that multiple damping springs 19 are welded to the bottom inner wall of the housing 1, and a conical shell 18 is welded to the top of the damping spring 19, and the conical shell 18 is in contact with the limiting plate 5.

[0031] A rubber column is fixed to the bottom inner wall of the conical shell 18 by bolts, and a damping spring 19 is sleeved on the outside of the rubber column. The conical shell 18 provides support for the limiting plate 5 under the action of the damping spring 19 and the rubber column.

[0032] The collection box 8 is placed inside the fixing frame 7. A baffle 6 is fixed to one side of the fixing frame 7 by bolts, and the collection box 8 can contact the baffle 6. The baffle 6 can restrict the position of the collection box 8.

[0033] The outer walls on both sides of the housing 1 are fixed with two hooks 9 by bolts, which makes it easy for workers to hang objects and pick them up. During transportation, the entire device can be placed in the conveying equipment.

[0034] Working principle: First, multiple comb plates are placed on the rubber frame 4 on the limiting plate 5 and the connecting plate 14 respectively. That is, the comb plates are placed in the two spaces divided by the partition plate 16 on the rubber frame 4. Then, the threaded rod 11 is rotated, so that the limiting plate 5 drives the comb plates in the rubber frame 4 connected to it to move upward until the convex plate 15 at the bottom of the connecting plate 14 contacts the comb plates on the limiting plate 5. Then, the threaded rod 11 continues to drive the limiting plate 5 to move upward, so that the comb plates on the limiting plate 5 push the connecting plate 14, so that the connecting plate 14 drives the comb plates placed inside it to move upward until the comb plates on the connecting plate 14 contact the convex plate 15 located at the bottom of the fixed plate 3, thereby separating and positioning the multiple comb plates for protection.

[0035] Then rotate the nut 10 to press it into contact with the adjacent mounting plate 12, thereby further fixing the position of the threaded rod 11.

Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model.
