Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides an overhead guardrail protection is with filling pillar, including right side half shell 1, one side of right side half shell 1 is provided with left side half shell 17, be provided with connecting piece 6 between right side half shell 1 and the left side half shell 17, one side of left side half shell 17 is provided with joint piece 4, one side of right side half shell 1 is provided with joint groove 5, the one end of right side half shell 1 and left side half shell 17 is provided with adapter sleeve 3, the inside cavity spring 13 that is provided with of right side half shell 1 and left side half shell 17, the screw thread is seted up at the both ends of right side half shell 1 and left side half shell 17, the inside cavity form that sets up of adapter sleeve 3, screw thread groove 7 has been seted up to the outer wall symmetry of adapter sleeve 3, flexible bag 10 is installed to the inner bottom end of screw thread groove 7, hollow bag 9 is installed to the one end that flexible bag 10 was kept away from to hollow bag 9, flexible bag 8 is installed to the one end that flexible bag 10 is inside to be filled with magnetorheological fluid, the inside of flexible bag 8 is filled with gel, the inside of hollow bag 9 is filled with air, the screw thread position is seted up to right side half shell 1 and left half shell 17 adopts magnet to make.
The inside of right side half shell 1 and left side half shell 17 sets up to the cavity, and a plurality of through-holes 12 have been seted up to right side half shell 1 and left side half shell 17 inside, and hollow spring 13 installs inside through-hole 12, and cooling chamber 11 has been seted up to the side of through-hole 12, and cooling hole 14 has been seted up to the inboard in cooling chamber 11, and cooling medium has been filled to cooling chamber 11 inside, and elasticity book pole 16 is installed to one side in cooling hole 14, and baffle 15 is installed to one end of elasticity book pole 16.
Working principle: utilize the cooperation between joint groove 5 and the joint piece 4 for two liang joint under the restriction of connecting piece 6 of right half shell 1 and left half shell 17, thereby wrap up the cable wire of inside, reach the purpose of abundant protection and quick installation, at this moment, insert the screw thread part of right side half shell 1 and left half shell 17 in adapter sleeve 3, and select the counter-rotation with both, make the screw thread of right side half shell 1 and left half shell 17 get into the inside of screw thread groove 7 because of the screw thread meshing gradually, utilize this kind of mode, can make a plurality of fill protection tube in a whole after the cover is in the cable wire surface, make the cable wire surface by totally covered, at this moment when external temperature is higher, because the screw thread part of right side half shell 1 and left half shell 17 does not get deep into the inside of screw thread groove 7, when high temperature makes cavity bag 9 take place the inflation, because the distance between the screw thread part of flexible bag 10 and right side half shell 1 and left half shell 17 is comparatively far, the magnetic field influence that the magnetorheological fluid of its inside receives is less, flexible bag 10 is whole, the flexible bag 10 is soft, flexible bag 10 is born the degree when the time, can bear the flexible bag 10 and can take a certain degree, can take place in the time and fill protection tube can take off the time, can take off the flexible bag 8 and fill in the flexible protection tube, can take off the time, can be filled in the pipe can be closely when the flexible pipe is filled in the pipe, can take off the time can be filled in the pipe, can be filled in the pipe is filled and can be filled in the pipe is filled and the pipe is filled, and the pipe is convenient.
When the external temperature is too high and the threaded parts of the right half shell 1 and the left half shell 17 do not extend into the threaded groove 7, the temperature rise causes the hollow pipeline to be heated and stretched, the hollow pipeline is stretched towards the two ends to open the through holes 12, meanwhile, the cooling cavity 11 is pressed, cooling medium in the hollow pipeline is extruded from the cooling hole 14, the baffle 15 is turned outwards, the elastic folding rod 16 is opened, the cooling medium cools the steel cable and the filled protecting pipe body, the hollow bag 9 is recovered when being cooled, the expansion bag 8 and the threaded part are prevented from being mutually pressed upwards to cause the expansion bag 8 to be broken, the filled protecting pipe and the connecting sleeve 3 at the moment can be separated at any time, when the hollow pipeline needs to be used for a long time, the threaded parts of the right half shell 1 and the left half shell 17 extend into the threaded groove 7, when the external temperature rises, the distance between the threaded parts and the flexible bag 10 is relatively short, magnetorheological fluid in the flexible bag 10 is affected by a magnetic field, the whole flexible bag 10 is hard, the hollow bag 9 is heated and expanded, the expansion bag 8 is jacked upwards, the expansion bag 8 is tightly contacted with the threaded part, the cooling degree of a cooling medium is insufficient to offset the degree of the heated and expanded hollow bag 9, the relative acting force between the expansion bag 8 and the threaded part is larger and larger, the expansion bag 8 is finally stressed to be broken, gel in the expansion bag is finally discharged, the gap in the threaded groove 7 is finally filled by the gel, the water in the gel is evaporated along with the high-temperature duration, the gel is hardened, and finally the filled protection pipe and the connecting sleeve 3 are connected in a seamless manner, so that the filled protection pipe is protected outside a steel cable for a long time, and the steel cable is prevented from being influenced by external environment to be overstrain.
