CN202171064U - Novel cable steel bracket - Google Patents

Abstract

The utility model discloses a novel cable steel bracket, which comprises an upright column having a U-shaped section and a plurality of support arms, wherein at least two long waist-type mounting holes are arranged on the upright column; the support arms are welded on the upright column; hot dipping galvanized layers are arranged on the support arms and the upright column; a nonmetal sheath is sleeved at the tail end of the support arm; and cable binding holes are arranged on the planes of the support arms. The cable bracket has quite strong corrosion resistances, such as acid, alkali, salt resistances, and is particularly suitable for humid, salt frog and chemical occasions. As the bracket employs a welding type, the novel cable steel bracket is more convenient for mounting than a combined cable bracket; the connection strength between the upright column and the support arms is higher than that of the combined cable bracket; the welding positions of the upright column and the support arm having different lengths can be selected according to specifications of different cable trenches so as to solve the problem of poor generality of the integrated cable bracket.

Description

The novel cable Steel Bracket

Technical field

The utility model relates to electric power facility auxiliary device technical field, exactly is meant a kind of steel cable bearer.

Background technique

Cable bearer is to be used for power industry to set up the member that cable transmits electric power, and is widely used in setting up of underground trench formula cable or setting up of subway tunnel cable.For example, increasing city utilizes subway to transport to alleviate traffic pressure, and the various facilities that match with subway also obtain more development and use with equipment, and the power transformating and supplying facility auxiliary device in the subway tunnel has all used cable bearer.And for example, the increasing overhead wire in city transform underground cable as and send electricity, all is provided with cable bearer in the underground trench.Cable bearer mainly partly is made up of the stull that fixes on the leg portion on trench or the tunnel-side together and fix on the pillar together, and pillar and stull have multiple structural type, and like integral type, separate assembling etc., used material also has multiple.The shortcoming of the cable bearer of integral structure is to exist versatility poor to different tunnels.Then there is the problem of inconvenient installation in the cable bearer of existing split fabricated construction.Like the patent No. is that the Chinese patent of ZL03208554.0 discloses a kind of " modular cable support ", includes column and stull, and stull and column removably connect, and adopts at least two clamping bolts in each stull of place that removably connects.Because adopt bolt to connect, there is the defective that installation workload is big, inconvenience is installed in this cable bearer.The modular cable support has and adopts the glass fibre reinforced plastics material in addition, though have that electrical insulation capability is superior, Corrosion Protection and flame retardant property be good, advantages such as simple installation, the loss of properties on aging of glass fibre reinforced plastics material, its intensity does not have the support of steel good.

The model utility content

The purpose of the utility model provides the integrated novel cable Steel Bracket of a kind of welding; Reduce installation workload, improve the intensity of support, there is the galvanizing by dipping layer on the surface; Have decay resistances such as very strong antiacid, alkali, salt, the occasion that is particluarly suitable for humidity, salt fog, chemical industry is used.

The utility model is achieved in that a kind of novel cable Steel Bracket; Form for column and some trailing arms of " U " type structure by the cross section; Said column is provided with at least two long waist type mounting holes, and it is characterized in that: described trailing arm is welded on the described column, and one deck galvanizing by dipping layer is arranged on said trailing arm and column; End at said trailing arm is set with non metallic sheath, on the plane of said trailing arm the cable tie hole is arranged.

The cross section of said trailing arm and column welding position is " 7 " type.

The utility model compared with prior art has following advantage:

1. owing to adopt the form of welding; Be convenient to more install than modular cable support; Join strength between column and the trailing arm is higher than modular cable support; Simultaneously can select the welding position of the column and the trailing arm of different length, solve the problem of the versatility difference of integral type cable bearer according to the specification of different cable channels.

2. owing to adopt the steel support, it is high that strength ratio adopts nonmetallic material to process the modular cable support, its long service life.

3. because one deck galvanizing by dipping layer is arranged on trailing arm and column, make support have decay resistances such as very strong antiacid, alkali, salt, be particluarly suitable for the occasion use of humidity, salt fog, chemical industry.

4. owing to be provided with non metallic sheath, can prevent that cable from coming off, scratching the workmen, plays beauty function again at the trailing arm end.

5. because the mounting hole on the column all is long waist-shaped hole, conveniently install.

6. trailing arm is provided with several long waist type cable tie holes, is convenient to the fixing of cable, prevents that cable from moving on trailing arm.

7. because " 7 " type is adopted in the cross section of the welding position of trailing arm and column, the convenient welding improved the intensity of trailing arm simultaneously.

Embodiment

Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model, and all technological schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each item claim.

As can be seen from Figure 1; A kind of novel cable Steel Bracket is made up of with some trailing arms 2 for the column 1 of " U " type structure the cross section, and said column 1 is provided with at least two long waist type mounting holes 3; It is characterized in that: described trailing arm 2 is welded on the described column 1; On said trailing arm 2 and column 1, one deck galvanizing by dipping layer is arranged, be set with non metallic sheath 4, cable tie hole 5 is arranged on the plane of said trailing arm 2 at the end of said trailing arm 2.

Said trailing arm 2 is " 7 " type with the cross section of column 1 welding position.

Claims (2)

1. novel cable Steel Bracket; Column ⑴ and some trailing arm ⑵ for " U " type structure form by the cross section; Said column ⑴ is provided with at least two long waist type mounting hole ⑶, and it is characterized in that: described trailing arm ⑵ is welded on the described column ⑴, and one deck galvanizing by dipping layer is arranged on said trailing arm ⑵ and column ⑴; End at said trailing arm ⑵ is set with non metallic sheath ⑷, and cable tie hole ⑸ is arranged on the plane of said trailing arm ⑵.

2. a kind of novel cable Steel Bracket according to claim 1 is characterized in that: the cross section of said trailing arm ⑵ and column ⑴ welding position is " 7 " type.
