Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides the following technical solutions: a filling protection tube for protecting an overhead guardrail comprises a right half shell 1, a left half shell 17 is arranged on one side of the right half shell 1, a connecting piece 6 is arranged between the right half shell 1 and the left half shell 17, a clamping piece 4 is arranged on one side of the left half shell 17, a clamping groove 5 is arranged on one side of the right half shell 1, a connecting sleeve 3 is arranged at one end of the right half shell 1 and one end of the left half shell 17, a hollow spring 13 is arranged inside the right half shell 1 and the left half shell 17, threads are arranged at two ends of the right half shell 1 and the left half shell 17, the inside of the connecting sleeve 3 is hollow, a thread groove 7 is symmetrically arranged on the outer wall of the connecting sleeve 3, a flexible bag 10 is arranged at the inner bottom end of the thread groove 7, a hollow bag 9 is arranged at one end of the flexible bag 10 far away from the inner bottom end of the thread groove 7, an extension bag 8 is arranged at one end of the hollow bag 9 far away from the flexible bag 10, magnetorheological fluid is filled inside the flexible bag 10, gel is filled inside the extension bag 8, the hollow capsule 9 is filled with air, and the threaded parts of the right half shell 1 and the left half shell 17 are made of magnets.
The working principle is as follows: by utilizing the matching between the clamping groove 5 and the clamping piece 4, the right half shell 1 and the left half shell 17 are clamped in pairs under the limitation of the connecting piece 6, so that the internal steel cable is wrapped, and the purposes of full protection and quick installation are achieved, at the moment, the thread parts of the right half shell 1 and the left half shell 17 are inserted into the connecting sleeve 3, and the two half shells are selected to rotate in opposite directions, so that the threads of the right half shell 1 and the left half shell 17 gradually enter the inside of the thread groove 7 due to thread engagement, by utilizing the mode, a plurality of filling protective pipes can be mutually connected into a whole after being sleeved on the surface of the steel cable, so that the surface of the steel cable is completely covered, at the moment, when the external temperature is higher, because the thread parts of the right half shell 1 and the left half shell 17 do not go deep into the inside of the thread groove 7, when the hollow bag 9 is expanded due to high temperature, because the distance between the flexible bag 10 and the thread parts of the right half shell 1 and the left half shell 17 is far, the influence of the magnetic field that its inside magnetorheological suspensions received is less, flexible bag 10 is whole comparatively soft this moment, when cavity bag 9 inflation, flexible bag 10 can bear the deformation of certain degree, it is inseparable not to make extension bag 8 and screw thread portion branch contact, the gel in the extension bag 8 can't flow this moment, when making reverse the packing pillar of twisting, can make packing pillar and adapter sleeve 3 break off and close, realize the convenient dismouting of packing the pillar, the packing pillar of this moment can be applied to the cable wire surface of short-term installation, and the packing pillar can be by reutilization.
When the external temperature is too high and the thread parts of the right half shell 1 and the left half shell 17 do not go deep into the thread groove 7, the hollow pipeline is heated and extended due to the temperature rise, the through hole 12 is expanded towards the two ends, the cooling cavity 11 is pressed at the same time, the cooling medium in the hollow pipeline is extruded out from the cooling hole 14, the baffle plate 15 turns outwards, the elastic folding rod 16 is expanded, the cooling medium cools the steel cable and the filling protective pipe body, the hollow bag 9 recovers when being cooled, the phenomenon that the hollow bag pushes up the extending bag 8 upwards and the thread parts are mutually pressed to cause the extending bag 8 to break is avoided, the filling protective pipe and the connecting sleeve 3 can be separated at any time, when the long-term use is needed, the thread parts of the right half shell 1 and the left half shell 17 go deep into the thread groove 7, when the external temperature rises, because the distance between the thread parts and the flexible bag 10 is close, the magnetorheological fluid in the flexible bag 10 is strongly influenced by the magnetic field, flexible bag 10 is whole comparatively hard this moment, cavity bag 9 at this moment is heated after the inflation will upwards jack-up extension bag 8, make extension bag 8 and screw thread part contact closely, the cooling degree of cooling medium is not enough to offset the degree that cavity bag 9 is heated to the inflation, finally, relative effort is bigger and bigger between extension bag 8 and the screw thread part, finally make extension bag 8 atress fracture, its inside gel flows out, finally the gel is filled the space in the thread groove 7, and along with the continuation of high temperature, the moisture evaporation in the gel, the gel sclerosis, finally make seamless connection before filling pillar and adapter sleeve 3, make the outside of filling the pillar and protecting the holding in the cable wire for a long time, avoid the cable wire to receive external environment influence and excessive strain.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
