Description
Technical field
The utility model relates to the technical field of Highspeed Catenary, especially a kind of cantilever support device pipe cap.
Background technology
China is geographical vast, and environmental difference is comparatively large, and environmental pollution is on the rise.The phenomenon that cantilever support device inside face sewage often appears in Highspeed Catenary, dust cannot be removed.
Pipe cap usually supports the use with cantilever support, and in high ferro contact system, mostly adopt soft pvc pipe cap, assembling mode is flexible connection, lightweight, easily comes off.And do not use NA, NB type pipe cap, because NA, NB type pipe cap and cantilever support fit system are that interference is connected, non-disconnectable connection, cannot clear up piece surface dust pollution thing in high ferro contact system scene, decay resistance declines, and brings unnecessary hidden danger to contact system.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model cantilever support device pipe cap can carry out on-site manual dismounting, and easy to operate, difficult drop-off, safety and reliability is high.
The utility model solves the technical scheme that its technical matters adopts: a kind of cantilever support device pipe cap, there is the pipe cap body of nylon material, pipe cap body comprises U-shaped pipe cap outer rim, the middle position of the interior diapire of pipe cap outer rim is provided with opening upwards and extends and the U-shaped pipe cap inner edge stretched out in outside pipe cap outer rim, the bottom of the lateral wall of pipe cap inner edge is provided with negative thread, and the top of the lateral wall of pipe cap inner edge offers interior wedge groove; Pipe cap also has and can be clamped in the lining of the nylon material of the convex of gap location between pipe cap outer rim and pipe cap inner edge by wedge, the bottom of the madial wall of lining is provided with the outside thread matched with negative thread, and the top of the madial wall of lining offers the outer wedge groove matched with interior wedge groove.
In order to make pipe cap body and lining mutually clamp, difficult drop-off, therefore the transition position of negative thread and interior wedge groove is positioned at the inside of pipe cap outer rim.
Be embedded in pipe cap body for the ease of lining, therefore the diameter dimension of interior wedge groove and outer wedge groove successively decreases from the bottom up successively.
The beneficial effects of the utility model are: this cantilever support device pipe cap, pipe cap body and lining are adopted the mode of elastic clamping, increase the assembling modes such as screw thread fixing and locking, R groove location simultaneously, make pipe cap can carry out on-site manual dismounting and cleaning pollutants very easily in high ferro contact system, sample and detect, easy to operate, avoid adopting the soft pipe cap of PVC, reduce pipe cap obscission, improve the safety and reliability that contact system uses.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of pipe cap body;
Fig. 2 is the structural representation of lining;
Fig. 3 is structural representation of the present utility model.
In figure: 1, pipe cap body, 1-1, pipe cap outer rim, 1-2, pipe cap inner edge, 1-2-1, negative thread, 1-2-2, interior wedge groove, 2, lining, 2-1, outside thread, 2-2, outer wedge groove.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Cantilever support device pipe cap as shown in Figure 1, Figure 2 and Figure 3, there is the pipe cap body 1 of nylon material, pipe cap body 1 comprises U-shaped pipe cap outer rim 1-1, the middle position of the interior diapire of pipe cap outer rim 1-1 is provided with opening upwards and extends and the U-shaped pipe cap inner edge 1-2 stretched out in outside pipe cap outer rim 1-1, the bottom of the lateral wall of pipe cap inner edge 1-2 is provided with negative thread 1-2-1, and the top of the lateral wall of pipe cap inner edge 1-2 offers interior wedge groove 1-2-2; Pipe cap also has and can be clamped in the lining 2 of the nylon material of the convex of gap location between pipe cap outer rim 1-1 and pipe cap inner edge 1-2 by wedge, the bottom of the madial wall of lining 2 is provided with the outside thread 2-1 matched with negative thread 1-2-1, and the top of the madial wall of lining 2 offers the outer wedge groove 2-2 matched with interior wedge groove 1-2-2.
Pipe cap and cantilever support support the use, when environment can not obtain effectively improving, by pipe cap body 1 and lining 2 being adopted the mode of elastic clamping, increase the assembling modes such as screw thread fixing and locking, R groove location simultaneously, pipe cap can be disassembled from cantilever support very easily, so that operating personal clears up cantilever support inside face dust pollution thing in time, adopt the sample detection method of gross pollution segments contact net parts, thus improve the decay resistance of cantilever support device.
Wherein, the transition position of negative thread 1-2-1 and interior wedge groove 1-2-2 is positioned at the inside of pipe cap outer rim 1-1, pipe cap body 1 and lining 2 is clamped mutually, difficult drop-off.The diameter dimension of interior wedge groove 1-2-2 and outer wedge groove 2-2 successively decreases from the bottom up successively, is convenient to lining 2 and is embedded in pipe cap body 1.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
