[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1The utility model provides an embodiment of a flat coal rod quick pulling-out device, comprising: a base 1, a table 2 is fixedly connected to the top of the base 1, a driving assembly is provided on the top front side of the table 2, the driving assembly includes a motor 3, a coupling 4 is installed at the output end of the motor 3, a worm 6 is fixedly connected to the right end of the coupling 4, a rotating shaft 8 is rotatably connected between the two brackets 5, a worm gear 7 is fixedly connected to the outside of the rotating shaft 8, the worm gear 7 is meshed with the worm 6, a reel 9 is fixedly connected to the outside of the rotating shaft 8, a steel wire is sleeved on the outside of the reel 9, one end of the steel wire is connected to a quick fixing assembly, the outside of the rotating shaft 8 is fixedly connected to the center of the outer shell 11 and the ratchet 13, the outer side of the ratchet 13 is rotatably connected to the inside of the outer shell 11, and the end of the worm 6 away from the coupling 4 is rotatably connected to the inside of the support block.

[0032] Specifically, in this embodiment, a table top 2 is fixedly connected to the top of the base 1, and a driving assembly is arranged at the top front side of the table top 2, which mainly includes a motor 3. The coupling 4 connects the motor 3 and the worm 6 together, which can ensure that the motor 3 transmits the torque to the worm 6. A rotating shaft 8 rotates between the two brackets 5, and a worm gear 7 is fixed on the outside of the rotating shaft 8. The motor 3 drives the worm 6 to rotate. Due to the engagement between the worm 6 and the worm gear 7, the worm gear 7 drives the reel 9 to rotate. A steel wire is sleeved on the outside of the reel 9, and a quick fixing assembly is fixed at one end of the steel wire. After the steel wire is connected to the flat coal rod, the motor 3 can reel in the steel wire to drag the flat coal rod out.

[0033] Reference Figure 1 , Figure 2 A locking assembly is installed on the outer side of the rear bracket 5, and two pulleys 10 are installed on the top left side of the base 1. The locking assembly includes an outer shell 11 and a ratchet 13. An inner ring 12 is installed on the front side of the outer shell 11. The rear side of the inner ring 12 is rotatably connected to two pawls 14. The inside of the inner ring 12 is fixedly connected to two limit columns 17. A tension spring 16 is installed between the end of the pawl 14 away from the limit column 17 and the limit column 17. The inside of the pawl 14 is rotatably connected to a fixed shaft 15. The steel wire is slidably connected to the outer side of the pulley 10, and the outer side of the pawl 14 abuts against the outer side of the ratchet 13. The driving assembly can drive the locking assembly to operate.

[0034] Specifically, a locking assembly is installed on the outer side of the rear bracket 5, and two pulleys 10 are installed on the top left side of the base 1, which can facilitate the steel wire to pull the flat coal rod. The locking assembly includes an outer shell 11 and a ratchet 13. An inner ring 12 is installed on the front side of the outer shell 11, and the rear side of the inner ring 12 is rotatably connected to two pawls 14. A tension spring 16 is installed between the pawl 14 and the limit column 17. The pawl 14 is pressed against the outer side of the ratchet 13 under the action of the tension spring 16, which can ensure that the reel 9 will not deflect when the flat coal rod is dragged.

[0035] Reference Figure 3The quick fixing assembly includes a clamp 18, and locking shafts 19 are slidably connected on both sides of the clamp 18. A spring 21 is sleeved on the outer side of the locking shaft 19. The middle part of the locking shaft 19 is fixedly connected to a limiting ring 22, and the front part of the locking shaft 19 is fixedly connected to a limiting ring 20. The quick fixing assembly is used to quickly connect the flat coal rod and the steel wire together, and the locking shaft 19 can be inserted into the socket at the end of the flat coal rod.

[0036] Specifically, the quick fixing assembly includes a clamp 18, and a locking shaft 19 slides inside the clamp 18. When fixing the flat coal rod, it is only necessary to pull the locking shaft 19 from one end, and the limit ring 22 is driven and compresses the spring 21. Then the clamp 18 is put on the outside of the flat coal rod socket. After loosening the locking shaft 19, the locking shaft 19 is inserted into the flat coal rod under the action of the spring 21, and the two ports can be connected from the end of the steel wire to fix the two ends of the flat coal rod, which can ensure stable transportation.

[0037] Working principle: After the motor 3 is running, it can drive the worm 6 to rotate, thereby driving the worm wheel 7 and the rotating shaft 8 to rotate. Since the drum 9 and the locking assembly are fixed on the outside of the rotating shaft 8, the two also rotate in a circular axis. At this time, the clamp 18 is sleeved on both sides of the flat coal rod, and the locking shaft 19 is inserted into the socket at the end of the flat coal rod. The spring 21 is used to achieve rapid fixation between the flat coal rod and the steel wire. As the drum 9 rotates, the flat coal rod is driven to move through the clamp 18. In order to prevent the danger caused by the flat coal rod's excessive resistance to the equipment, which may cause the rotating shaft 8 to reverse, a locking assembly is installed on the rear side of the rotating shaft 8. When the equipment is normally reeling in the steel wire, the locking assembly will not work. When the rotating shaft 8 may reverse, the pawl 14 will immediately get stuck on the outside of the ratchet 13 to prevent the rotating shaft 8 from reversing, and there is also a certain locking function between the worm 6 and the worm wheel 7.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
