[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] Reference Figure 1The first and second side plates 1 and 3 are fixedly mounted by the positioning column 2, and the second side plates 3 are rotatably connected with a pinion 4. A threaded rod 5 is coaxially fixed on the pinion 4, and a wire guide 6 is threadedly connected to the threaded rod 5. The wire guide 6 is used for guiding the cable when winding, so as to avoid winding multiple layers of cables at the same position on the winding drum 8. A limiting column 7 is also fixedly connected between the first side plate 1 and the second side plate 3, and the wire guide 6 is sleeved on the limiting column 7. A winding drum 8 is also rotatably connected between the first side plate 1 and the second side plate 3, and a wiring seat 9 is fixedly connected to the winding drum 8. The wiring seat 9 is used for fixing the cable. The length of the cable wound on the winding drum 8 is 12m, so that the cable can be rolled on it when the winding drum 8 rotates. A large gear meshing with the pinion 4 is also provided at the bottom of the winding drum 8, which can drive the pinion 4 to rotate stably, thereby driving the wire guide 6 to move, thereby avoiding uneven cable winding.

[0030] Reference Figure 2 A check wheel 10 is provided on the first side plate 1, a clamping rod 11 is rotatably connected to the first side plate 1 and located on one side of the check wheel 10, a spring 12 is provided on the first side plate 1 and located on the other side of the check wheel 10, and an electromagnet 13 is also fixedly connected to the first side plate 1, which can well adsorb the clamping rod 11, so that the clamping rod 11 will not affect the normal rotation of the winding drum 8.

[0031] Reference Figure 2 The card rod 11 is provided with a card block that is compatible with the convex teeth on the non-return wheel 10. The card rod 11 is located between the electromagnet 13 and the non-return wheel 10. The card rod 11 is reset under the action of the spring 12, and the convex teeth on it contact the non-return wheel 10, so that the non-return wheel 10 is limited and will no longer rotate, thereby causing the flag to stop at the current position. The material of the card rod 11 is magnetic metal, preferably iron alloy, one end of the spring 12 is fixedly connected to one end of the card rod 11, and the other end of the spring 12 is fixed to the first side plate 1.

[0032] Reference Figure 1 A driving motor is fixedly connected to the bottom of the first side plate 1 and inside the winding drum 8. The driving motor is fixed to the first side plate 1 by bolts, and the output end of the driving motor is coaxially fixed to the winding drum 8. The winding drum 8 is coaxially fixed to the check wheel 10. A positioning block 14 is also provided on the first side plate 1. The number of the positioning blocks 14 is four groups, which are used to assist the installation of the lifter.

[0033] The implementation principle of this embodiment is:

[0034] The first step is to install the auxiliary lifter under the flagpole, fix the auxiliary lifter through four sets of positioning blocks 14, and then fix the cable used for flag lifting on the wiring seat 9.

[0035] In the second step, when the flag needs to be raised, the drive motor and the electromagnet 13 are started. The electromagnet 13 generates a magnetic field to attract the clamping rod 11, and the output shaft of the drive motor drives the winding drum 8 to rotate, so that the cable is wound on the winding drum 8, so that the flag can be raised under the drive of the cable. When it is raised to the top of the flagpole, the drive motor is turned off, and the electromagnet 13 is turned off at the same time. The clamping rod 11 is reset under the action of the spring 12, and the convex teeth on the clamping rod 11 clamp the check wheel 10, so that the flag is positioned at the highest point of the flagpole.

[0036] In the third step, the large gear at the bottom of the winding drum 8 drives the small gear 4 to rotate, so that the threaded rod 5 rotates. Through the threaded connection between the wire guide 6 and the threaded rod 5, it can move in the vertical direction as the winding drum 8 rotates, so that the cable winding is more uniform.

[0037] In the description of the present invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "both ends" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0038] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
