An auxiliary mechanism for assisting the fixing of the lamp 18 is provided on the support tube 11.

[0035] Reference Figure 4 , Figure 8 and Fig. 9As shown, the auxiliary mechanism includes a second take-up roller 31, which is rotatably connected to the lower part of the support tube 11, and the second take-up roller 31 is located below the first take-up roller 14. The second take-up roller 31 is fixedly connected to a second worm gear 32, and the lower part of the support tube 11 is rotatably connected to a second worm 33 meshing with the second worm gear 32. A circular hole is provided at a position where the support tube 11 contacts the extended line of the second worm 33, and the second worm 33 is provided with a hexagonal limiting groove. The hexagonal limiting groove on the second worm 33 is the same size as the hexagonal limiting groove on the first worm 13, and the second take-up roller 31 is wound around a The second pull rope 34 and the second guide wheel 35 are installed at the upper end of the support tube 11. The second pull rope 34 starts from the second take-up roller 31, passes around the second guide wheel 35, and is rewound onto the second take-up roller 31. The two ends of the second pull rope 34 are wound on the second take-up roller 31 in opposite directions. When the second take-up roller 31 rotates, one end of the second pull rope 34 is released and the other end is wound, so that the second pull rope 34 is always in a taut state. The second pull rope 34 is fixedly connected with a square transmission rod 36. The square transmission rod 36 is located at the upper end of the support tube 11. The square transmission rod 36 is slidably connected to the support tube 11 to ensure The square transmission rod 36 moves up and down stably, and the upper end of the support tube 11 is rotatably connected to the first transmission rod 37, and the first transmission rod 37 cooperates with the square transmission rod 36 for transmission. The square transmission rod 36 is provided with evenly distributed square protrusions, and the left side of the first transmission rod 37 is provided with evenly distributed square depressions. The square depressions of the first transmission rod 37 cooperate with the adjacent square protrusions on the square transmission rod 36 to transmit the power of the square transmission rod 36 to the first transmission rod 37. The first transmission rod 37 is rotatably connected to the fixed plate 2, and the fixed block 17 is threadedly connected with a rotating ring 38, and the rotating ring 38 is connected to the first transmission rod 37. A transmission rod 37 is used for transmission cooperation, and a rotating ring 38 is provided with evenly distributed square depressions. The left side of the first transmission rod 37 is provided with evenly distributed square protrusions. The square depressions of the rotating ring 38 cooperate with the adjacent square protrusions on the first transmission rod 37 to transmit the power of the first transmission rod 37 to the rotating ring 38. The rotating ring 38 is limitedly cooperated with the two clamping jaws 22 and the first limit block 23. When in use, the right side of the first transmission rod 37 is sleeved on the outside of the two clamping jaws 22 and the first limit block 23 to limit the two clamping jaws 22 and the first limit block 23, thereby improving the stability of the lamp 18.

[0036] Before using the device for lighting work, the staff first fixes the support tube 11 to the position to be installed. Initially, the fixing block 17 and the lamp 18 are located at the lower part of the support tube 11. Then the staff passes the hex wrench through the circular hole on the upper side of the support tube 11 until the hex wrench enters the first worm 13. Then the hex wrench is turned to rotate the first worm 13. The first pull rope 15 is reeled up through the transmission. The first pull rope 15 drives the fixing block 17 to move upward. The fixing block 17 drives the counterweight block 171 and the lamp 18 to rise slowly. The counterweight block 171 is used to prevent the uneven force on the first pull rope 15, which makes it difficult to move the fixing block 17 upward.

[0037] During the rising process of the lamp 18, the platform on the upper side of the lamp 18 gradually contacts the lower plane of the first limit block 23 (initially, the clamp 22 opens under the gravity of the first limit block 23), and then presses the first limit block 23 upward. The first limit block 23 drives the two clamps 22 to close while moving upward. The clamp 22 and the first limit block 23 wrap the left end of the lamp 18 to fix the lamp 18 to prevent the lamp 18 from shaking. Then the staff takes out the hex wrench.

[0038] After the lamp 18 is fixed, the staff inserts the Allen wrench into the second worm 33 through the circular hole on the lower side of the support tube 11, and then rotates the Allen wrench to rotate the second worm 33. The second worm 33 moves the second pull rope 34 through transmission, and the second pull rope 34 drives the square transmission rod 36 to move downward. The square transmission rod 36 drives the first transmission rod 37 to rotate during the downward movement, and the first transmission rod 37 drives the rotating ring 38 to rotate. The rotating ring 38 is limited by the thread on the fixed block 17. The rotating ring 38 gradually wraps the two clamping jaws 22 and the first limit block 23 during the movement to the right, and the rotating ring 38 fixes the two clamping jaws 22 and the first limit block 23. When the rotating ring 38 moves to the right to half of its length, it stops, and then the staff takes out the hex wrench to complete the fixation. At this time, the two clamping jaws 22 and the first limit block 23 are limited by the rotating ring 38, and the two clamping jaws 22 and the first limit block 23 clamp the lamp 18, thereby improving the stability of the lamp 18.

[0039] When the bulb on the lamp 18 needs to be repaired, the staff first inserts the hexagonal wrench into the second worm 33 through the circular hole on the lower side of the support tube 11, and then reversely rotates the second worm 33. The second worm 33 drives the square drive rod 36 to move upward, and the square drive rod 36 drives the rotating ring 38 to rotate in the opposite direction through the first drive rod 37. The rotating ring 38 gradually shrinks to the left under the action of the thread on the fixed block 17, so that the rotating ring 38 is disengaged from the clamping jaws 22 and the first limit block 23, and then the hexagonal wrench is taken out.

[0040] After the above actions are completed, the staff will use the Allen wrench to reversely rotate the first worm gear 13, and the first worm gear 13 will release the first pull rope 15 through transmission. During the release of the first pull rope 15, the fixed block 17, the counterweight block 171 and the lamp 18 move downward under the action of gravity, causing the lamp 18 to descend. After the lamp 18 descends to a position that is convenient for workers to disassemble, it stops, allowing the staff to repair the lamp 18 without affecting the normal traffic of the lane. After the repair is completed, the staff repeats the above installation process, raises the lamp 18 to the top of the support tube 11, and fixes it.

[0041] Example 2: Based on Example 1, refer to Figure 9-11 As shown, a protective mechanism is also included, which is arranged on the fixed block 17 and is used to protect the lamp 18.

The sliding blocks 4 are rotatably connected to the sliding telescopic rod 41. The right side of the lamp 18 is fixedly connected to a connecting frame 42. The connecting frame 42 is triangular and is used to provide a more stable supporting force. The telescopic end of the sliding telescopic rod 41 is rotatably connected to the lower side of the connecting frame 42. Initially When the two sliding telescopic rods 41 are in a V shape, the upper side of the support tube 11 is slidably connected to the left and right sides with two second limit blocks 43 symmetrically distributed front and back, the two second limit blocks 43 are respectively limited and matched with the adjacent sliding blocks 4, the second limit blocks 43 are provided with evenly distributed elastic triangular blocks, and the sliding blocks 4 are also provided with evenly distributed elastic triangular blocks.

[0042] Reference Figure 10-13As shown, the locking assembly includes two steel wires 5 symmetrically distributed front and back, the right ends of the two steel wires 5 are fixed to the connecting frame 42, two first hydraulic telescopic rods 51 symmetrically distributed front and back are fixed in the fixed block 17, the left end of the steel wire 5 passes through the fixed block 17 and is fixed to the telescopic end of the adjacent first hydraulic telescopic rod 51 therein, a limit column is arranged in the fixed block 17, the steel wire 5 moves under the guidance of the limit column of the fixed block 17, a spring 52 is arranged in the first hydraulic telescopic rod 51 to keep it contracted, a liquid storage shell 53 is fixed to the fixed block 17, hydraulic oil is stored in the liquid storage shell 53, and the liquid storage shell 53 passes through the liquid storage shell 53. The first conduit 54 is connected to the two first hydraulic telescopic rods 51, and a one-way valve is provided in the first conduit 54. The liquid in the first conduit 54 can only flow into the two first hydraulic telescopic rods 51 through the one-way valve. The fixed block 17 is fixedly connected to two second hydraulic telescopic rods 56 distributed symmetrically with the center. The telescopic ends of the second hydraulic telescopic rods 56 are fixedly connected to the adjacent sliding blocks 4 through square blocks. The first hydraulic telescopic rod 51 and the second hydraulic telescopic rod 56 are connected through the second conduit 55. A one-way valve is provided in the second conduit 55. The hydraulic oil in the second conduit 55 can only flow into the second hydraulic telescopic rod 56.

[0043] Reference Fig.12 and Fig.13 As shown, the liquid storage shell 53 is connected to the first connecting tube 6, the first connecting tube 6 is connected to the second connecting tube 61, the second connecting tube 61 is connected to two second hydraulic telescopic rods 56 symmetrically distributed in the center, the second hydraulic telescopic rod 56 is provided with a tension spring 62 to keep it contracted, the first connecting tube 6 is sealed and slidably connected with a sealing column 63, the sealing column 63 is used to block the first connecting tube 6, initially, the first connecting tube 6 is in a connected state, the first connecting tube 6 is provided with an elastic member to keep the sealing column 63 popped out, and the elastic member is a spring.

[0044] Reference Fig.14 As shown, the limiting assembly includes a rotating seat 64, which is rotatably connected to the upper part of the support tube 11, and the rotating seat 64 is in transmission cooperation with the square transmission rod 36. The rotating seat 64 is threadedly connected with a sliding rod 65, and the sliding rod 65 is composed of three cross bars and a longitudinal rod connecting the three, and the middle cross bar is short. The sliding rod 65 is slidably connected to the support tube 11, and the ends of the sliding rod 65 on the front and rear sides are respectively fixedly connected to the symmetrically distributed second limiting blocks 43, and the fixed block 17 is slidably connected with the second transmission rod 66, and the second transmission rod 66 is fixedly connected to the sealing column 63. The sliding rod 65 is squeezed and cooperated with the second transmission rod 66, and the sliding rod 65 is limited and cooperated with the fixed block 17.

[0045] In the process of fixing the lamp 18, it is necessary to move the square transmission rod 36 downward. In the process of moving downward, the square transmission rod 36 drives the rotating seat 64 to rotate. The rotating seat 64 drives the sliding rod 65 to move to the right under the limit of the thread. The sliding rod 65 drives the second limit block 43 to move to the right, so that the second limit block 43 protrudes out of the support tube 11. The middle part of the sliding rod 65 squeezes the second transmission rod 66. The second transmission rod 66 squeezes the sealing column 63, so that the sealing column 63 blocks the first connecting tube 6 and squeezes the elastic part of the first connecting tube 6. Then the square transmission rod 36 stops moving, and the lamp 18 is fixed.

[0046] When the device encounters strong winds, in order to prevent the lamp 18 from being damaged due to shaking, the lamp 18 is additionally supported when it shakes. The specific operation is as follows:

[0047] When the lamp 18 shakes, the lamp 18 drives the connecting frame 42 to shake, and the connecting frame 42 drives the wire rope 5 to shake. When the connecting frame 42 shakes, it tilts, and the connecting frame 42 will pull the wire rope 5 outward (taking the forward swing of the lamp 18 as an example, when the lamp 18 swings forward, the connecting frame 42 tilts, and its rear side tilts to the right to pull the wire rope 5 at the rear side). Take the wire rope 5 at the rear side as an example (the same applies to the first pull rope 15 at the front side), when the wire rope 5 at the rear side is pulled, the wire rope 5 drives the telescopic end of the first hydraulic telescopic rod 51 at the rear side to move backward and squeeze the hydraulic oil therein. The hydraulic oil in the first hydraulic telescopic rod 51 enters the second hydraulic telescopic rod 56 through the second conduit 55 and passes through the one-way valve in the second conduit 55. The telescopic end of the second hydraulic telescopic rod 56 moves forward under the squeeze of the hydraulic oil and drives the sliding block 4 at the front side to move forward. The sliding block 4 drives the sliding telescopic rod 41 to move. Since the wind is indirect Intermittent blowing. When the wind stops, the first hydraulic telescopic rod 51 is reset under the elastic force of the spring 52, and drives the wire rope 5 to reset. During the resetting process of the first hydraulic telescopic rod 51, the first hydraulic telescopic rod 51 absorbs the hydraulic oil in the liquid storage shell 53 through the first conduit 54 and passes through the one-way valve in the first conduit 54. When the wind blows again, the rear wire rope 5 is pulled again, and the above process is repeated. The front sliding block 4 continues to move forward through transmission until the sliding block 4 drives the sliding telescopic rod 41 to be parallel to the lamp 18 (the sliding telescopic rod 41 is the shortest at this time). At this time, the sliding telescopic rod 41 shrinks to the limit position, and the front sliding block 4 contacts the support tube 11. When the lamp 18 swings forward again, the lamp 18 squeezes the front sliding telescopic rod 41 through the connecting frame 42. The sliding telescopic rod 41 transmits force to the support tube 11 through the sliding block 4, supports the right side of the lamp 18, and prevents the lamp 18 from shaking.

[0048] During the forward movement of the sliding block 4 on the front side, the front side of the sliding block 4 gradually disengages from the fixed block 17, slides relative to the support tube 11, and contacts the adjacent second limit block 43. The second limit block 43 prevents the sliding block 4 from resetting through the elastic triangular block thereon.

[0049] When it is necessary to lower the lamp 18, it is necessary to move the square transmission rod 36 upward first. During the upward movement of the square transmission rod 36, the square transmission rod 36 drives the rotating seat 64 to rotate in the opposite direction, so that the sliding rod 65 shrinks to the left, and the sliding rod 65 drives the second limit block 43 to move to the left. The second limit block 43 shrinks into the support tube 11 and disengages from the sliding block 4, releasing the limit on the sliding block 4. The middle part of the sliding rod 65 disengages from the second transmission rod 66 at the same time, and the second transmission rod 66 and the sealing column 63 are released. The sealing column 63 is reset under the action of the elastic member in the first connecting tube 6, so that the first connecting tube 6 is reconnected with the second connecting tube 61. At this time, the tension spring 62 pulls the telescopic end of the second hydraulic telescopic rod 56 to shrink, and the hydraulic oil in the second hydraulic telescopic rod 56 flows back to the liquid storage shell 53 through the second connecting tube 61 and the first connecting tube 6. During the contraction of the telescopic end of the second hydraulic telescopic rod 56, the sliding block 4 is reset. Then the staff rotates the first worm 13 with the Allen wrench to lower the lamp 18.
