Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rail transportation safety monitoring, and in particular relates to an extra-long protective tube lead-wire traction device. Background Art
[0002] During safety monitoring, to prevent the monitoring lines from being damaged, the outside of the safety monitoring lines is usually protected. This is typically done using a PVC protective tube, through which the monitoring lines are inserted and buried in concrete. For shorter monitoring points that require insertion into the protective tube, some can be inserted directly or using a steel wire as a guide. If this isn't possible, the monitoring points can be cut and inserted in sections, which can cause monitoring operations to be interrupted or delayed. When monitoring buried monitoring points during the construction of the ground-connected wall in the rail transit departure shaft (generally at a greater depth) requires monitoring, traditional methods cannot fully insert the monitoring point line into the protective tube at one time. Due to the cross-operation involved in welding the ground-connected wall reinforcement, it's impossible to see the monitoring line inserted in advance. Typically, the monitoring line is inserted into the protective tube as the steel cage is hoisted during the rail transit departure shaft ground-connected wall construction. To ensure the complete insertion of the monitoring line into the protective tube, workers are typically required to climb to the top of the cage and manually pull the monitoring line, often posing a significant safety hazard. Utility Model Content

[0015] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the technical solution of the present invention will be further described in detail below with reference to the accompanying drawings.
[0016] like Figure 1 、 Figure 2 As shown, the utility model provides an extra-long protective tube lead traction device, including a support rod 1, a pulley 20, a connecting assembly 2 and a traction rope 9. The support rod 1 is fixed on the steel cage 4, the connecting assembly 2 can be hung on the support rod 1, the pulley 20 is rotatably installed on the connecting assembly 2, the traction rope 9 is wound around the pulley 20 and one end of the traction rope is used to pass through the protective tube 3 on the steel cage 4 and connect with the monitoring line 8.
[0017] When using this device, it is necessary to weld the support rod 1 to the steel cage 4 before lifting the steel cage 4, then hang the connecting assembly 2 on the support rod 1, wrap the traction rope 9 around the pulley 20, and one end of the traction rope 9 needs to pass through the protective tube 3, and then start lifting the steel cage 4. After the steel cage 4 is lifted, the staff continuously lowers the traction rope 9 so that the traction rope 9 passes through the protective tube 3 and moves down to an appropriate height, and then the staff connects the monitoring line 8 with the traction rope 9, and then the staff pulls up the traction rope 9 until the monitoring line 8 passes through the protective tube 3.
[0018] It should be noted that the protection tube 3 is installed on the steel cage 4 before the steel cage 4 is lifted. It can be a whole tube or a plurality of short tubes connected and spliced together.
[0019] The height at which the support rod 1 is fixed needs to ensure that the pulley 20 is above the protective tube 3, and the support rod 1 needs to be tilted when welded, so as to prevent the connecting component 2 hung on the support rod 1 from slipping, thereby being safer and more reliable.
[0020] The connecting assembly 2 includes a lifting ring 10, a sleeve 13, a rotating shaft 12 and a U-shaped mounting plate 22. The lifting ring 10 is fixedly connected to the sleeve 13, the rotating shaft 12 is movably inserted into the sleeve 13, the U-shaped mounting plate 22 is movably connected to the rotating shaft 12, and the pulley 20 is rotatably mounted on the U-shaped mounting plate 22. A shift rod 11 is provided at the top of the rotating shaft 12, and a circular nut 17 is provided at the bottom end of the rotating shaft 12. The U-shaped mounting plate 22 includes a wing top 18 and two wing walls 19. The two wing walls 19 are symmetrically integrally formed at both ends of the wing top 18. The wing top 18 is movably sleeved on the rotating shaft 12. The two ends of the pulley 20 axle are respectively rotatably embedded in the bottom ends of the two wing walls 19. A spring 16 is connected between the bottom surface of the sleeve 13 and the top surface of the wing top 18.
[0021] The lifting ring 10 is used to hang on the support rod 1, the rotating shaft 12 is movably inserted into the sleeve 13, and the top and bottom ends of the rotating shaft 12 are respectively provided with a stop rod 11 and a circular nut 17, the wing top 19 is movably sleeved on the rotating shaft 12, the circular nut 17 can prevent the wing top 18 from sliding off from the bottom end of the rotating shaft 12, and the stop rod 11 can prevent the top end of the rotating shaft 12 from sliding out of the sleeve 13.
[0022] A spring 16 is provided between the bottom surface of the sleeve 13 and the top surface of the wing top 18 . The spring 16 acts as a buffer and shock absorber to ensure that the device can be reused, extend its life, and be safer.
