[0020] First of all, it should be noted that the following will specifically illustrate the specific structure, characteristics and advantages of the present utility model by way of examples. However, all the descriptions are only for the purpose of explanation and should not be construed as any limitation to the present utility model. In addition, any single technical feature described or implied in each embodiment mentioned in this article, or any single technical feature shown or implied in each drawing, can still be arbitrarily combined or deleted between these technical features (or their equivalents) to obtain more other embodiments of the present utility model that may not be directly mentioned in this article. In addition, for the sake of simplifying the drawings, the same or similar technical features may only be marked in one place in the same drawing.

[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] Example 1

[0023] As shown in the figure, the built-in lifting drive device of the high mast lamp provided in this embodiment includes a frame 1. In this embodiment, the frame 1 is of a cuboid structure, and one of its sides is in an open form. A motor 15 is fixedly installed inside the frame 1. The output end of the motor is connected to a reduction gearbox 20. The reduction gearbox drives a driving gear 14 to rotate. The driving gear meshes with a driven gear 2 and can drive the driven gear to rotate;

[0024] The driven gear 2 is fixedly installed at one end of a reel shaft 9, and a reel sleeve 7 is sleeved on the surface of the reel shaft. The other end of the reel shaft 9 is fixedly installed with a reel baffle 3; Specifically, as Figure 2 shown, both ends of the reel shaft 9 are inserted into second bushings 8 that can rotate along the reel shaft 9. The reel sleeve 7 is fixedly sleeved on the second bushing 8, and the driven gear and the reel baffle 3 are respectively fixed on the second bushings 8 at both ends of the reel shaft 9.

[0025] In addition, an opening is provided at the top of the frame. The opening is directly opposite the reel sleeve 7 below. Two limiting rods 4 are arranged in the axial direction of the reel shaft below the opening. A roller shaft 6 is fixedly installed between the two limiting rods, and a rotatable first bushing 5 is sleeved on the roller shaft; The limiting rod 4 is used to limit the steel wire rope wound around the reel sleeve 7 within a certain area to prevent the steel wire rope from coming out of the groove during winding; The first bushing 5 can be a round tube made of nylon. The bushing 5 is sleeved on the roller shaft 6. Since the steel wire rope moves up and down, when the steel wire rope contacts the bushing 5 during its up and down movement, the bushing can rotate, so that the steel wire rope is not worn;

[0026] The worm wheel of the reduction gearbox is made of phosphor bronze, and the worm is made of copper tooth surface. The helix angle of the worm is smaller than the friction surface, which ensures that the worm and worm wheel have good wear resistance and realizes full mechanical self-locking during the lifting process. Considerable improvements have been made in the braking principle and the effective components, completely eliminating the delay and failure of locking. Even in the case of sudden power failure, it can achieve instant power-off and instant suspension, completely eliminating potential safety hazards.

[0027] One side of the frame is of an open structure, and reinforcing plates 11 are fixedly installed in the left and right directions on this open surface; Moreover, mounting slots 21 are provided on the panels on both sides of the open surface of the frame. When the device is installed in a hanging manner, the frame can be inserted into a suspension rod through the mounting slots, and then a limiting plate 18 is fixedly installed at the edge of the mounting slots to prevent the suspension rod from coming out. Moreover, the presence of the reinforcing plate 11 can reinforce this open side, so that the device will not deform easily when installed in a hanging manner.

[0028] A limit switch bracket 19 is also installed on the frame. A limit switch is provided on the limit switch bracket 19. When the limit function is required, the limit switch bracket 19 can be fastened to the frame housing, and then the purchased standard limit switch is installed on this bracket. There is a structure on the upper end of the wire rope that cooperates with the limit switch. When the wire rope winds to this structure, the limit switch gives a stop signal to make the motor stop running.

[0029] The speed reducer is installed on the side wall of the frame through a speed reducer connecting seat 16. A driving gear shaft 13 is connected to the speed reducer, and a driving gear 14 is installed on the driving gear shaft. The end of the driving gear shaft is installed on the frame through a deep groove ball bearing, as Figure 2 shown, the bearing disc 12 is installed on the frame 1, serving as a fixing part for fixedly connecting the shaft end of the speed reducer.

[0030] A retaining ring 10 is also included. The retaining ring is installed on the drum shaft 9 to limit the movement of the second bushing 8.

[0031] When using this device, one end of the wire rope is wound around the drum sleeve 7, and the other end is connected to the lamp panel. A pulley mechanism is provided at the top of the high mast lamp. Through the cooperation of the pulley mechanism, when the wire rope is tightened, the lamp panel is raised to the high mast lamp. When the wire rope is released, under the gravity of the lamp panel, the end of the wire rope drops to the ground, facilitating maintenance personnel to repair the lamps.

[0032] The above embodiments have described the present invention in detail, but the content described is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
