[0066] In this embodiment, the driving member 8 is a hydraulic driving system or a lifting machine.

[0067] Embodiment 4

[0068] On the basis of embodiment 3, the middle support 5 is replaced by the pulley support in embodiment 1. The driving member 8 is replaced by a winch and a rope. The winch is provided in two, which are the first winch 81 and the second winch 82. The rope is provided in two, which are the first rope and the second rope.

[0069] The double-lifting lighting device of the high-pole lamp of this embodiment further comprises a rope distribution body. The rope distribution body is provided in two, which are the first rope distribution body 83 and the second rope distribution body 84.

[0070] Among them, the support rod 1 in embodiment 1 is the pole body of the high-pole lamp. The middle of the support rod 1 is a hollow structure, so that a control chamber is formed in the support rod 1.

[0071] The first winch 81, the first rope, and the first rope distribution body 83 are used to drive the lifting of the first lifting member 6. The second winch 82, the second rope, and the second rope distribution body 84 are used to drive the lifting of the second lifting member 7.

[0072] The first rope body 83 is a disc body structure, and a rope connecting part 831 is arranged in the middle of the lower part of the first rope body 83. The rope connecting part 831 matches the joint 842 in the embodiment 2. Three rope connecting parts 831 are uniformly arranged in the upper part of the first rope body 83.

[0073] The second rope body 84 adopts the rope structure in the embodiment 2.

[0074] The space in the middle of the first lifting member 6 is a passing cavity. The middle part of the second rope body 84 also forms a passing cavity. For the convenience of description, the passing cavity in the first lifting member 6 is defined as a first passing cavity, and the passing cavity in the second rope body 84 is defined as a second passing cavity. The second passing cavity is used for the first rope body 83 to pass through.

[0075] The second rope body 84 forms a guide surface. The first rope body 83 and the second rope body 84 are arranged in the control cavity. The guide surface is used for guiding the second rope body 84 and the inner wall surface of the control cavity. The guide surface is an arc-shaped rounded surface 843.

[0076] The second hoist 82 is provided with two, and the first hoist 81 is provided with one. The first hoist 81 is arranged in the middle part of the support rod 1, and the second hoist 82 is arranged in the edge part of the support rod 1.

[0077] When the first lifting member 6 and the second lifting member 7 are lowered, the second lifting member 7 is first lowered to the lowermost part of the support rod 1, and then the first lifting member 6 is lowered to the lowermost part of the support rod 1. When the first lifting member 6 and the second lifting member 7 are raised, the first lifting member 6 is first raised from the lowermost part of the support rod 1 to the top support 4, and then the second lifting member 7 is raised from the lowermost part of the support rod 1 to the pulley support. When the first lifting member 6 is raised to the top support 4, the first lifting member 6 is locked and fixed with the top support 4 through a locking structure 9. When the second lifting member 7 is raised to the pulley support, the second lifting member 7 is locked and fixed with the pulley support through a locking structure 9.

[0078] The first rope is composed of a plurality of first ropes 85, one end of one of the first ropes 85 is connected with the first hoist 81, and the other end is connected with the first rope body 83. The other plurality of ropes are connected with the first rope body 83 at one end, and extend upward to the top support 4 at the other end. The top support 4 is provided with a guide wheel, which is rotatably connected with the top support 4. The first rope 85 extends downward after passing through the guide wheel, and is connected with the first lifting member 6, so that the first rope drives the first lifting member 6 to lift. Since a plurality of first ropes 85 are fixed with the first lifting member 6, the lifting process of the first lifting member 6 is more stable.

[0079] The second rope is composed of a plurality of second ropes 86, one end of one of the second ropes 86 is connected with the second hoist 82, and the other end is connected with the fixed rod 841 on the second rope body 84. The other plurality of ropes are connected with the second rope body 84 at one end, and extend upward to the pulley support, enter the installation housing 3 from the inlet, pass through the pulley 35, exit the installation housing 3 from the outlet, and are fixed with the second lifting member 7 after extending downward. Thus, the second rope drives the second lifting member 7 to lift. Since a plurality of second ropes 86 are fixed with the second lifting member 7, the lifting process of the second lifting member 7 is more stable.

[0080] Thus, the first rope body 83 and the second rope body 84 move with the first lifting member 6 and the second lifting member 7. Therefore, the first rope body 83 and the second rope body 84 will interfere with each other during movement. The second passage in the second rope body 84 allows the first rope body 83 to pass through the second rope body 84, thereby solving this problem.

[0081] A plurality of guide members 87 are arranged on the outer wall of the support rod 1, and the guide members 87 are used to form guide lines. The guide members 87 are rod bodies, and the guide lines are the generatrix of the guide members 87. The guide lines form a wrapping area with the support rod 1, which wraps the pulley support. Both ends of the guide lines are connected with the support rod 1. The guide lines are used to guide the first passage of the first lifting member 6, thereby avoiding the expansion of the first lifting member 6 and the pulley support.

[0082] A connecting flange body 11 is formed on the support rod 1, and the connecting flange body 11 is used to form the first abutting surface 12. The connecting flange body 11 is formed in the middle of the support rod 1.

[0083] The first lifting member 6 and the second lifting member 7 are both provided with a lighting lamp 10.
