DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In order to solve the technical problem that a workbench loses stability too quickly, the utility model provides a bridge lighting installation platform, which can prolong the time when the workbench loses stability.

[0026] It should be noted that the bridge lighting installation platform described in the utility model is used for but not limited to bridge lighting installation, etc. For the convenience of explanation, in the utility model, only a bridge lighting installation platform applied to bridge lighting installation is used as an example for explanation. The principle of applying a bridge lighting installation platform to other types of equipment is essentially the same as the principle applied to bridge lighting installation, and will not be elaborated here.

[0027] See also Figure 1 , Figure 1 This is a structural schematic diagram of a bridge lighting installation platform in one embodiment of the utility model. A bridge lighting installation platform includes a counterweight frame 1, a truss 2 and a lifting mechanism 3. The truss 2 is fixedly connected to the top of the counterweight frame 1, and a guide rail 21 is provided at the end of the truss 2. The lifting mechanism 3 includes a guide rod 31, a workbench 32, a rope 33 and a driving member 34. The guide rod 31 is slidably embedded in the guide rail 21, and a safety protrusion 311 is provided at the top of the guide rod 31. The bottom end of the guide rod 31 is fixedly connected to the workbench 32, one end of the rope 33 is fixedly connected to the workbench 32, and the other end of the rope 33 is connected to the driving member 34. The driving member 34 is used to drive the rope 33 to pull the workbench 32 up and down.

[0028] In this embodiment, the guide rod 31 on the workbench 32 is slidably connected to the guide rail 21, and a safety protrusion 311 is provided on the top of the guide rod 31, so that when the rope 33 breaks due to aging, the guide rod 31 will slide down along the guide rail 21 until the safety protrusion 311 gets stuck on the guide rail 21 or the guide rod 31 tilts, causing the friction with the guide rail 21 to increase, so that the guide rod 31 cannot continue to slide, thereby ensuring the stability of the workbench 32 and effectively avoiding safety accidents caused by the shaking of the workbench 32.

[0029] First, the counterweight frame 1 drives the truss 2 and the lifting mechanism 3 to the preset position; then, the construction workers step onto the workbench 32; finally, the driving member 34 is started, the rope 33 drives the workbench 32 to descend, and the guide rod 31 moves downward along the guide rail 21 until the workbench 32 reaches the preset height.

[0030] Furthermore, the guide rod 31 adopts a ladder structure, which is convenient for workers to enter and exit the workbench 32 by climbing the guide rod 31 .

[0031] In order to mitigate the rigid collision between the safety protrusion 311 and the guide rail 21 , the safety protrusion 311 can be inserted into the guide rail 21 in a trapezoidal shape, and the guide rod 31 will stop descending as the width of the safety protrusion 311 increases.

[0032] In order to mitigate the rigid collision between the safety protrusion 311 and the guide rail 21 , a buffer rubber may also be provided on the top of the guide rail 21 .

[0033] In one embodiment, see Figure 1 There are two trusses 2 and two guide rods 31. The two trusses 2 are relatively arranged on the top of the counterweight frame 1. The ends of the two trusses 2 are provided with guide rails 21. The two guide rods 31 are respectively slidably embedded in the two guide rails 21, and the bottom ends of the two guide rails 21 are respectively fixedly connected to the two ends of the workbench 32.

[0034] In one embodiment, see Figure 1 There are two ropes 33 and two driving members 34. One end of the two ropes 33 is fixedly connected to the two ends of the workbench 32, and the other end of the two ropes 33 is connected to the two driving members 34. In this embodiment, the driving member 34 adopts a servo motor. The two driving members 34 work synchronously through the PLC computer terminal, so that the two ropes 33 run synchronously, and the two ends of the workbench 32 are connected to the ropes 33, so that the workbench 32 can be stably lifted and lowered.

[0035] In one embodiment, see Figure 1, buckles 321 are fixedly connected at both ends of the workbench 32, and a hook 331 is provided at one end of the rope 33 connected to the workbench 32, and the hook 331 is detachably connected to the buckle 321. In this embodiment, the hook 331 is detachably connected to the buckle 321, which facilitates the separation of the rope 33 from the workbench 32, and then the rope 33 can be maintained or replaced.

[0036] Furthermore, the hook 331 has a self-locking function to prevent the hook 331 from automatically detaching from the buckle 321 .

[0037] In one embodiment, see Figure 1 The opposite ends of the two trusses 2 are hinged with guide wheels 22, and the guide wheels 22 are rotatably connected with the ropes 33. In this embodiment, the guide wheels 22 are used to connect the ropes 33 to the workbench 32 after the ropes 33 are in a vertical state, so that when the ropes 33 pull the workbench 32, the workbench 32 can be lifted vertically.

[0038] In one embodiment, see Figure 2 The tops of the two trusses 2 are fixedly connected with a receiving box 23, a driving wheel 231 is hinged in the receiving box 23, and a driving member 34 is connected to the driving wheel 231 and is used to drive the driving wheel 231 to rotate and wind or release the rope 33. In this embodiment, the receiving box 23 is used to protect the movable end of the driving member 34 and the driving wheel 231 to prevent rain from reducing the service life. In addition, the fixed end of the driving member 34 is fixedly connected to the receiving box 23, and the movable end of the driving member 34 passes through the receiving box 23 and is fixedly connected to the driving wheel 231.

[0039] In one embodiment, see Figure 1 A connecting rod 24 is fixedly connected between the two containing boxes 23. In this embodiment, the function of the connecting rod 24 is to improve the stability of the two trusses 2.

[0040] Furthermore, in order to improve the stability of the trusses 2 , more than two connecting rods 24 are arranged between the two trusses 2 .

[0041] In one embodiment, see Figure 1 , one end of the truss 2 away from the guide rail 21 is connected with a counterweight 25. In this embodiment, the counterweight 25 is a cement block, and the function of the counterweight 25 is to improve the stability of the workbench 32.

[0042] In one embodiment, see Figure 1A bracket 11 is provided on the top of the counterweight frame 1, one end of the bracket 11 is fixedly connected to the top of the counterweight frame 1, and the other end of the bracket 11 is fixedly connected to the truss 2. In this embodiment, there are two brackets 11, each of which is used to connect the truss 2 and the counterweight frame 1. The height of the bracket 11 makes the truss 2 higher than the guardrail on the bridge, so that the workbench 32 can be suspended for operation.

[0043] Furthermore, in order to improve the stability of the truss 2 , reinforcing ribs are provided between the bracket 11 and the truss 2 .

[0044] Furthermore, in order to improve the practicability of the device, the bracket 11 has a telescopic function, so that the device is suitable for guardrails of different heights.

[0045] In one embodiment, see Figure 1 , a roller 12 is provided at the bottom of the counterweight frame 1. In the present embodiment, the roller 12 is used to facilitate the movement of the counterweight frame 1, so that the staff can realize the construction of the whole section of the bridge without leaving the workbench 32.

[0046] Preferably, the roller 12 is connected to a servo motor, and the servo motor drives the roller 12 to rotate, thereby driving the counterweight frame 1 to move.

[0047] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0048] First, the roller 12 rotates and drives the counterweight frame 1 to move, so that the workers do not need to evacuate the workbench 32 to realize the construction of the entire section of the bridge; then, ensure that the hook 331 at the end of the rope 33 is normally connected with the buckle 321 of the workbench 32, and the construction workers board the workbench 32; finally, start the driving member 34, the rope 33 drives the workbench 32 to descend, and the guide rod 31 moves downward along the guide rail 21 until the workbench 32 reaches the preset height. At this time, the workbench 32 relies on the two ropes 33 to achieve suspended operation. Among them, if any one of the ropes 33 has an accident, the guide rod 31 on the same side will lose balance, and the guide rod 31 changes from the original vertical state to an inclined state and moves downward, so that the friction between the guide rod 31 and the inner wall of the guide rail 21 increases. As the friction increases, the guide rod 31 will eventually stop moving downward, or the safety protrusion 311 will stop the guide rod 31 from moving downward by clamping the top of the guide rail 21, effectively ensuring the stability of the workbench 32 and avoiding safety accidents caused by the shaking of the workbench 32.

[0049] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
