Detailed Description
As shown in fig. 1, this high-rise building cable shaft, including installing shaft main part 1 that the internal perpendicular to horizontal plane of building set up, shaft main part 1's inside has a shaft chamber 2, more than one cable 4 sets up in shaft chamber 2, every cable 4 all is provided with an automatic wiring device 3, 3 bottom fixed mounting of every automatic wiring device are on the bottom surface of shaft chamber 2, all connect through an air duct 5 between the respective automatic wiring device 3 and switch on, shaft main part 1's bottom is facing every cable and all runs through a through-hole that sets up, the one end of cable 4 is fixed on automatic wiring device 3, all the other parts are located shaft main part 1's outside, after automatic wiring device 3 jacks up, lie in shaft main part 1 outside cable 4 by shaft to draw-in chamber 2, automatic wiring device 3 jacks up after aerifing through outside gas charging apparatus.
As shown in fig. 3, each of the automatic wiring devices 3 includes a bottom plate 35, a movable plate 31, more than one inflation rod 37 and more than one sliding device, the more than one inflation rod 37 is fixedly mounted on the bottom plate 35, the other end of the more than one inflation rod 37 is connected to the lower end surface of the movable plate 31, cable holes for cables to pass through are formed in the bottom plate 35 and the movable plate 31, the outer diameter of each cable hole is larger than that of each cable 4, the cables 4 pass through the bottom plate 35 and the movable plate 31 from the bottom and extend out of the top of the movable plate, the more than one sliding device is mounted at the bottom of the movable plate 31, the cables 4 pass through the middle of the sliding device, and the sliding device is slidably mounted on the inflation rods.
When the inflation rod 37 is inflated and expanded, the sliding device is positioned and fixed at the topmost part of the inflation rod 37 through the expanded inflation rod 37, and when no gas exists in the inflation rod 37, the sliding device slides to the bottommost part along the inflation rod, passes through the cable 4, and sequentially extinguishes the flame on the cable 4.
Each sliding device comprises a sliding sleeve 34, more than one connecting rod 38 and more than one movable ring 36, each connecting rod 38 is fixedly provided with one movable ring 36, the other end of each connecting rod 38 is fixedly connected with the sliding sleeve 34, each movable ring 36 is movably arranged on an inflating rod 37, a movable through hole with the inner diameter smaller than the outer diameter of a cable by 0.1-0.2mm is arranged in the middle of each sliding sleeve 34, each movable through hole is arranged in the middle of each movable ring 36, and when the sliding devices slide downwards, the movable through holes are almost equal to the outer diameter of the cable, so that the sliding sleeves can be used for contacting burning flames, and extinguishment is realized by using a physical friction mode.
Wherein, more than one sliding device is sequentially arranged at the bottom of the movable plate 31 in an up-down overlapping mode, the inner diameters of the sliding holes of the movable rings in each sliding device are different, the diameter of the sliding hole nearest to the movable plate 31 is the smallest, and the diameter of the sliding hole far away from the movable plate 31 is the largest. After the inflation rod is inflated and expanded, all the movable rings are fastened on the inflation rod 37, because the inner diameter of the bottommost sliding hole is the largest, when the inflation rod 37 leaks air, the outer diameter of the inflation rod 37 is reduced, when the outer diameter of the inflation rod 37 is smaller than the inner diameter of the bottommost sliding hole, the bottommost movable ring drives the sliding sleeve to slide downwards along the cable and the inflation rod, and the flame is extinguished by using the friction between the sliding sleeve and the outer wall surface of the cable, as shown in fig. 2, the outer diameter of the inflation rod is smaller and smaller with the continuous escape of the gas in the inflation rod, when the outer diameter of the inflation rod is smaller than the inner diameter of the sliding hole at the top, the penultimate movable ring is also loosened, at the moment, the movable ring drives the sliding sleeve to slide downwards along the cable, and so on, until all the sliding devices slide from the top to the bottommost and stop, and during the period, the sliding sleeve slides downwards in an intermittent state, therefore, the fire source is extinguished in a physical friction mode through the sliding sleeve which continuously slides downwards, and finally the purpose of extinguishing fire is achieved. When a certain cable is natural, the flame can be used for quickly destroying the inflating rod of the rubber, so that the inflating rod which is originally expanded is continuously shrunk, and the sliding device is gradually loosened.
Wherein, the inflation rods 37 are all made of rubber materials, the inflation rods 37 are communicated with each other through the air guide tubes 5, the outer part of the shaft main body 1 is provided with an inflation hole 6, the inflation hole 6 is connected with an external high-pressure inflator pump, the output end of the inflation hole is provided with an air outlet main tube (not shown), the air outlet main tube is provided with a one-way air inlet valve, the air outlet main tube is communicated with one air guide tube 5, the top of each movable plate 31 is provided with a fixed shaft sleeve 33, one side of the fixed shaft sleeve is provided with a locking screw 32, the cable 4 passes through the fixed shaft sleeve 33 and is locked and positioned through the locking screw 32 on one side, the bottom plate is fixedly arranged on the bottom surface of the cavity of the shaft through screws, when wiring is needed, the cable does not need to be carried to move to the topmost part of the building body, only one end of the cable is fixed, then, and then the gas enters the gas charging rod, so that the gas charging rod is expanded and jacked up, the gas charging rod which is continuously charged with gas is jacked up, the cable is driven to continuously rise until the gas charging rod is completely charged and jacked up, gas backflow is prevented through the one-way gas inlet valve, and the gas quantity in the gas charging rod can be always ensured.
Wherein, sliding sleeve 34 all adopts a metal disc, through setting up the metal disc for sliding sleeve is more smooth and easy at the gliding in-process, and the dead weight is bigger, prevents to meet the protruding section and can not the automatic condition that glides.
The invention has the beneficial effects that: the cable well lifting device can quickly arrange cables in the cable well, simplifies manpower and material resources, improves efficiency, simultaneously realizes the safety of later-stage cable use by utilizing the lifting device, reduces the occurrence of fire accidents, not only facilitates the arrangement of the cables, but also can increase the safety of the cable well in use through the same structure.
