Abstract
The utility model relates to a kind of contact net bar bolt tarpaulins.The tarpaulin is provided with cavity (1), inside the cavity (1) setting from the internal screw thread (2) with contact net bar bolt (3), the tarpaulin outer surface is provided with anti-skid structure.The shank of bolt tarpaulin of the utility model generally speaking has following technical characteristic, and one is internally provided with screw thread in tarpaulin, enhances its connection relationship between bolt, and mount and dismount all extremely convenient;Secondly being provided with anti-skid structure outside tarpaulin, the installation and removal of operator are facilitated, prevent the slipping phenomenon generated in operation;Tarpaulin open end is provided with sealing structure form simultaneously, has further prevented the entrance of the impurity such as water, foreign matter, has further improved protective performance.
Description
Technical field
The utility model relates to a kind of contact net bar bolt tarpaulins, belong to railway equipment protection technology field.
Background technique
Contact net is to set up along rail overhead "the" shape in electric railway, take the high pressure of stream defeated for pantograph
Electric wire.Contact net is the main truss of railway electrification project, is that powering to electric locomotive for downline overhead erection is special
The transmission line of electricity of form.
In order to keep the safety of transmission line of electricity, generally related electric equipment sealed set, and pass through the fasteners such as bolt
Realize being fastenedly connected for seal box, bolt is often exposed among air at this time;Because environment is more severe in outdoor, warp
Often by the invasion of the weather such as rainwater, such as it is not added to protect, bolt is easy to happen damage, to influence the service performance of contact net.
Existing safeguard structure is generally as follows: contact net bar bolt tarpaulin is inserted into bolt, to protect the weather-proof antirust of bolt
Erosion so as to repair demolition, but finds that this tarpaulin bottom intakes, is easy to fall off, when disassembly skids.
Utility model content
The utility model can carry out contact net bar bolt in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structurally reasonable
The contact net bar bolt tarpaulin well protected.
The technical solution adopted in the utility model is thus: contact net bar bolt tarpaulin, and the tarpaulin setting is free
Chamber (1), inside the cavity (1) setting from the internal screw thread (2) with contact net bar bolt (3), the tarpaulin outer surface
It is provided with anti-skid structure.
The internal circumferential interruption of the cavity (1) is provided with the positioning surface for positioning the contact net bar bolt (3), the positioning
The internal screw thread (2) for positioning the contact net bar bolt (3) is provided on face.
Waterproof cap surface top is formed with the anti-skid structure of seamed edge.
The anti-skid structure is hexgonal structure form.
Cavity (1) open end circumferential direction offers sealed groove (4), is provided with sealing strip (5) and is embedded in the groove
(4) in.
The utility model has the advantages that: the shank of bolt tarpaulin of the utility model generally speaking has following technology special
Sign, one are internally provided with screw thread in tarpaulin, enhance its connection relationship between bolt, and mount and dismount all extremely
It is convenient;Secondly being provided with anti-skid structure outside tarpaulin, the installation and removal of operator are facilitated, are prevented in operating process
The slipping phenomenon of middle generation;Tarpaulin open end is provided with sealing structure form simultaneously, has further prevented water, foreign matter etc. miscellaneous
The entrance of matter, further improves protective performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the interior views of figure.
Fig. 3 is the utility model another kind structure type schematic diagram.
Fig. 4 is the bottom view of Fig. 3.
Fig. 5 is the installation diagram of the prior art.
1 it is cavity in figure, 2 be internal screw thread, 3 be contact net bar bolt, 4 be groove, 5 is sealing strip.
Specific embodiment
Contact net bar bolt tarpaulin, the tarpaulin are provided with cavity 1, inside the cavity 1 setting by and contact net
The internal screw thread 2 that bar bolt 3 cooperates, the tarpaulin outer surface is provided with anti-skid structure.
The 1 inside circumferential direction of cavity, which is interrupted, is provided with the positioning surface for positioning the contact net bar bolt 3, on the positioning surface
It is provided with the internal screw thread 2 for positioning the contact net bar bolt 3.
Waterproof cap surface top is formed with the anti-skid structure of seamed edge.
The anti-skid structure is hexgonal structure form.
The 1 open end circumferential direction of cavity offers sealed groove 4, is provided with sealing strip 5 and is embedded in the groove 4.
Specifically form following two structure type:
Embodiment one:
It is as shown in Figure 1, 2:
One contact net bar bolt tarpaulin of new departure screws in bolt such as figure, to protect the weather-proof anti-corrosion of bolt, repair demolition
When screw out, this tarpaulin bottom adds a circle sealing strip 5 to prevent into water, due to internal threading arrangement, not firmly do not fall off, due to
Top is hexagon, and when disassembly is not easy to skid.
Embodiment two:
It is as shown in Figure 3,4:
Two contact net bar bolt tarpaulin of new departure such as figure insertion bolt, last several teeth due to the threaded structure of tarpaulin,
Tarpaulin is screwed, this scheme reduces the circle number of front end screw-in, improves work efficiency, protects bolt weather-proof and antirust
Erosion;It is screwed out when repair demolition, this tarpaulin bottom adds a circle sealing strip 5 to prevent from, due to internal threading arrangement, not exerting oneself into water
It does not fall off, since top is hexagon, when disassembly is not easy to skid.
