This device can ensure the stability of the ladder assembly. At the same time, once the ladder is damaged and falls off, the ladder can be suspended to prevent it from falling directly into the well. At the same time, when the user is climbing, the user's safety can be guaranteed to avoid falling off the ladder. The practicality is strong, but the patent still has the following problems in actual use:

[0003] The ladder of the above-mentioned device is still fixed by bolts and cannot be installed quickly.

Such ladder rods can be embedded in the well wall when pouring, which is convenient for installation. However, as the ladder rods are subjected to long-term stress, the connection point between the rod body and the concrete well wall will gradually wear the concrete. Coupled with environmental factors, the embedded ladder rods will eventually become loose and deformed, affecting their use and creating safety hazards.

[0004] A vibration-proof deep well climbing device for bridge engineering is proposed to solve the above-mentioned problems. Utility Model Content

[0029] The spring 207 is sleeved on the outside of the mounting sleeve 205, the limiting bevel 206 can fit with the limiting ring 203, the movable sleeve 204 is slidably connected to the inner wall of the fixed sleeve 201, and the two ends of the spring 207 are respectively fixed to the middle part of the mounting sleeve 205 and the side of the limiting ring 203, and the climbing component 2 is located between the well wall 1 and the mesh cover 101; the spring 207 can push the movable sleeve 204 to move horizontally, so that the slope protrusion 209 is always fitted to the outside of the ball pocket groove 208 under normal conditions to prevent the ball 210 from sliding out of the ball pocket groove 208, so that the ball 210 is no longer engaged with the positioning ball groove 212, and when the positioning ball groove 212 is engaged with the ball 210, the top surface of the ball 210 overlaps the slope protrusion 209, and when the mounting sleeve 205 moves, the spring 207 will shrink accordingly.

[0030] The safety mechanism 3 includes a sliding tube 301 fixedly connected to both ends of the mesh cover 101, a sliding sleeve 302 is slidably connected to the sliding tube 301, and a rotating rod 303 is rotatably connected to the side of the sliding sleeve 302, and the rotating rod 303 is arranged obliquely upward; the outer end of the rotating rod 303 is fixedly connected to a connecting ring 304, the inner end of the rotating rod 303 is rotatably connected to a pressing plate 305, and the bottom surface of the pressing plate 305 is fixedly connected to a friction rubber 306, and there is a gap between the friction rubber 306 and the sliding tube 301; the friction rubber 306 can increase the friction force between the pressing plate 305 and the sliding tube 301 to form a locking effect, and the gap between the friction rubber 306 and the sliding tube 301 can ensure that when the rotating rod 303 rotates slightly, the pressing plate 305 will not fit the sliding tube 301, thereby preventing the sliding sleeve 302 from randomly locking, and the oblique rotating rod 303 is always subjected to a pulling force from obliquely above.

[0032] Working principle: Before using this anti-shake deep well climbing device for bridge engineering, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, when the pedal rod 211 needs to be replaced or installed, first press the movable sleeve 204 to slide inside the fixed sleeve 201, so that the spring 207 shrinks due to the extrusion until the ramp protrusion 209 completely leaves the outside of the pocket ball groove 208, at which time a part of the ball 210 below will fall out of the pocket ball groove 208 and overlap the movable sleeve 204, and then the pedal rod 211 is inserted into the installation sleeve 205. During this process, the pedal rod 211 will push the ball 210 to slide in the pocket ball groove 208, so that the upper The ball 210 will fall into the locking ball groove 212, and finally the movable sleeve 204 is loosened so that the spring 207 pushes the movable sleeve 204 to move horizontally, so that the lower ball 210 is pushed into the ball groove 208 again along the slope of the ramp protrusion 209 and engages with the locking ball groove 212, so that the deformed pedal rod 211 can be quickly replaced, avoiding the need to use a large number of bolts during installation, saving installation time, and avoiding the connection between the pedal rod 211 and the well wall 1 from loosening and deforming due to long-term use, which may cause safety hazards;

[0033] Before going down the well, the worker buckles the safety buckle on the connecting ring 304, and then removes the binding of the suspension rope 309 to the suspension ring 308, so that the sliding sleeve 302 can slide down freely and is always below the worker. The rotating rod 303 is always subjected to the force from the upper oblique direction, and the friction rubber 306 is not in contact with the sliding tube 301. When the worker falls accidentally, the worker's falling speed is greater than the sliding speed of the sliding sleeve 302, so that the rotating rod 303 will rotate due to the change in the height of the worker, so that the pressure plate 305 pushes the friction rubber 306 to fit closely to the sliding tube 301, and then the sliding sleeve 302 is locked on the sliding tube 301, and finally the worker is suspended to prevent him from falling, thereby reducing casualties caused by accidents.
