As shown in fig. 1, according to the utility model discloses high pole lamp auto-lock elevating gear, include: the lamp post 100, the lamp post 100 is a hollow column; a wire rope 200; the lamp panel 300 is sleeved outside the lamp post 100, one end of the steel wire rope 200 is connected with the lamp panel 300, and the lamp panel 300 can ascend and descend along the lamp post 100; the driving assembly 400 is arranged inside the lamp post 100, the other end of the steel wire rope 200 is connected with the driving assembly 400, and the driving assembly 400 is used for winding or releasing the steel wire rope 200; and the self-locking assembly 500 is arranged inside the lamp pole 100, the steel wire rope 200 penetrates through the self-locking assembly 500, and the self-locking assembly 500 can clamp the steel wire rope 200.
For example, as shown in fig. 1, the lamp post 100 is a truncated cone with a narrow top and a wide bottom, the lamp panel 300 is sleeved outside the lamp post 100, the lamp holder is connected with the driving assembly 400 through the steel wire rope 200, and the driving assembly 400 winds up the steel wire rope 200 to lift the lamp panel 300. When the driving assembly 400 retracts the steel wire rope 200 and the lamp panel 300 ascends, the self-locking assembly 500 does not influence the sliding of the steel wire rope 200; however, when the steel wire rope 200 slides and the lamp panel 300 descends due to operation errors or equipment faults, the self-locking assembly 500 clamps the steel wire rope 200 to prevent the lamp panel 300 from descending, and the self-locking function is realized. Therefore, the lamp panel 300 is prevented from falling due to misoperation or equipment failure, and the safety of operators and equipment is guaranteed.
In some embodiments of the present invention, the self-locking assembly 500 comprises: a first pulley 510, the first pulley 510 being disposed at an upper end of the lamp pole 100; the first chute 520 is arranged on the inner side of the first pulley 510, the lower end of the first chute 520 is far away from the first pulley 510, and the upper end of the first chute 520 is close to the first chute 520; and a clamping wheel 530, the clamping wheel 530 is disposed in the first sliding groove 520, the wire rope 200 passes through the space between the first pulley 510 and the clamping wheel 530, and the sliding of the wire rope 200 can drive the clamping wheel to roll along the length direction of the first sliding groove 520.
For example, as shown in fig. 4 to 6, when the driving assembly 400 retracts the steel cable 200, the first pulley 510 rotates counterclockwise, the clamping wheel 530 rotates clockwise, the clamping wheel 530 is located at the bottom of the first sliding groove 520, the clamping wheel 530 is not clamped, the sliding of the steel cable 200 is not affected, and the lamp panel 300 is normally lifted; when the steel wire rope 200 slides due to misoperation or equipment failure, the first pulley 510 rotates clockwise, the clamping wheel 530 is driven by the steel wire rope 200 to roll upwards along the first sliding groove 520, and the upper end of the first sliding groove 520 is closer to the first pulley 510 than the lower end of the first sliding groove 520, so when the clamping wheel 530 ascends to the upper end of the first sliding groove 520, the first pulley 510 and the clamping wheel 530 act together to clamp the steel wire rope 200, and the lamp panel 300 is prevented from falling.
Therefore, the self-locking function of preventing the lamp panel 300 from falling is realized by adding the first sliding groove 520 and the clamping wheel 530 to the existing high-pole lamp structure, and the self-locking assembly 500 is arranged at the position shown in fig. 1, so that the lamp panel 300 can be prevented from falling due to the failure of the driving assembly 400 and the steel wire rope 200 between the driving assembly 400 and the self-locking assembly 500.

In the case of a failure of the high-pole lamp lifting device or an operator operation error, when the lamp panel 300 is accidentally lowered: as shown in fig. 6, the second pulley 550 is default to be located at the innermost position of the second sliding groove 540, the steel wire rope 200 is in contact with the clamping wheel 530, the steel wire rope 200 slides clockwise around the first pulley 510, the clamping wheel 530 is driven by the sliding of the steel wire rope 200 to roll upwards until the clamping wheel 530 rolls to the position of the upper end of the first sliding groove 520, the upper end of the first sliding groove 520 is closer to the first pulley 510 than the lower end of the first sliding groove 520, the clamping wheel 530 located at the upper end of the first sliding groove 520 and the first pulley 510 cooperate to clamp the steel wire, so that the sliding of the steel wire rope 200 is prevented, and the self-locking lifting device of the high-pole lamp enters a locking state to prevent the lamp panel 300 from falling.
When the trouble that leads to lamp panel 300 to fall is solved, operating personnel need relieve this high-Pole lamp auto-lock elevating gear's locking state: as shown in fig. 7, the first motor first controls the second pulley 550 to slide to the outermost position of the second sliding groove 540, the driving assembly 400 retracts the wire rope 200, the clamping wheel 530 slides to the lower end of the first sliding groove 520, and the locking state is released.
Therefore, the self-locking lifting device of the high-pole lamp can realize the normal lifting of the lamp panel 300 and prevent the lamp panel 300 from falling.
In some embodiments of the present invention, the self-locking assembly 500 has multiple sets and is disposed along the circumference of the lamp post 100. For example, as shown in fig. 1 and 2, three sets of self-locking assemblies 500 can ensure that each steel cable 200 is uniformly stressed; meanwhile, when one self-locking assembly 500 fails, the rest self-locking assemblies 500 still can play a role in preventing the lamp panel 300 from falling, and the reliability of the self-locking lifting device of the high-pole lamp is further improved.
In some embodiments of the present invention, the driving assembly 400 includes: a drum 410, on which the wire rope 200 is wound; and a second motor 420, the second motor 420 being used to drive the reel 410 to reel in and reel out the wire rope 200. For example, as shown in fig. 1, the second motor 420 and the winding drum 410 are disposed inside the lower end of the light pole 100, which is convenient for an operator to control and repair them. The second motor 420 drives the winding drum 410 to rotate, so as to realize the winding and releasing of the steel wire rope 200.
In some embodiments of the present invention, the method further comprises: the pulley bracket 110, the pulley bracket 110 is set on the lamp pole 100, the pulley bracket 110 extends out to the outside; and a third pulley 120, the third pulley 120 being disposed on an end of the pulley bracket 110 away from the lamp pole 100. For example, as shown in fig. 1 and 2, the pulley bracket 110 is disposed at the upper end of the lamp post 100, and the third pulley 120 is disposed at an end of the pulley bracket 110 away from the lamp post 100, during the process of lifting the lamp panel 300, an included angle between the steel wire rope 200 and the lamp panel 300 is increased due to the disposition of the third pulley 120, and the tensile stress borne by the steel wire rope 200 is reduced.
