Abstract
The utility model discloses a protective device used for enabling a cable to penetrate a steel tube. The device comprises two protective rings mounted at the two ends of the penetrated steel tube respectively, wherein, each protective ring is made of steel reinforcements, and a plurality of bearings used for protecting the cable are uniformly sleeved on the ring bodies; and a limit nut is arranged between each two adjacent bearings on the protective rings. The utility model has the advantages of compact structure, convenient assembly and disassembly, good protective effect, enables the cable penetration operation to be more time-saving and labor-saving, and can avoid the cable to be scratched and damaged by end ports of the steel tube.
Description
Technical field
The utility model relates to a kind of cable protective device, especially relates to a kind of cable and passes through the steel pipe protector.
Background technology
In the engineering construction process; the normal steel pipe that uses protects cable; but when cable passes through steel pipe; cable is scratched by sharp steel pipe port through regular meeting; cause scrapping of cable when serious; just need continue or cabling again, this problem is a puzzlement construction technical staff technical barrier for many years.
In the practice, multiple different solution is arranged: encase the steel pipe port with cotton yarn cable is protected, or the steel pipe port is done flue, or the PVC composite tube is set in steel pipe to protect cable by sliding damage at this problem.These methods can not effectively be dealt with problems, and its shortcoming is that protection effect is poor, and the workman extremely requires great effort when the pulling cable passes through steel pipe.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cable to pass through the steel pipe protector, its compact conformation at above-mentioned deficiency of the prior art, easy accessibility, make that to pass through wireline operation more time saving and energy saving, and can avoid cable to be scratched by the steel pipe port and damage, protection effect is good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cable passes through the steel pipe protector, it is characterized in that: comprise two protective rings that are installed in the steel pipe two ends of passing through respectively, described protective ring make by reinforcing bar and its ring body on evenly be set with a plurality of bearings that are used for protective cable.
Between adjacent two bearings, be provided with stop nut on the protective ring.
The radius of described protective ring is not less than the radius of described steel pipe.
Described protective ring is installed in described steel tube end part by the clip of setting coaxial with it, described clip is the tubular body made of band steel and is sleeved on the described steel pipe port outside, described clip and protective ring are all having breach on the relative position up and down, and the breach two ends of described clip are connected with locking member.
Described locking member is a bolt, and the two ends of described clip tube wall breach are all to being outside equipped with mounting panel, and bolt is interspersed to be installed on two mounting panels, and by the cooperation with nut clip is fixed on the described steel pipe port outside.
Fixedly connected between described protective ring and the clip by a plurality of equally distributed strutting pieces.
Described strutting piece is made by reinforcing bar, between described protective ring and the strutting piece, and is between strutting piece and the clip and is welded to connect.
The number of described strutting piece is four.
The utility model compared with prior art has the following advantages: 1, compact conformation is easy to carry.2, simple to operate, easy accessibility: the utility model is installed in the required both ends of passing through steel pipe of cable by bolt, its good fixing effect, and dismounting, install very conveniently, when passing through operation, effectively saved the operating time by cable.3, the protection effect to passing through cable is good: though cable from which angle inlet pipe, the bearing on the protective ring can both protect cable, avoids cable to run into the steel pipe port, causes damage because of the phase mutual friction then.Need pulling force little when 4, cable passes through: in the prior art, to require great effort very much when the pulling cable passes through longer steel pipe; And the utility model middle (center) bearing is subjected to the frictional force effect that produces between the two when cable passes through, and axial rotation on its installation site is so bearing when cable is protected, has been avoided the phenomenon of dragging firmly with rough power.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
As depicted in figs. 1 and 2, the utility model comprises two protective rings 5 that are installed in the steel pipe two ends of passing through respectively, protective ring 5 make by reinforcing bar and its ring body on evenly be set with a plurality of bearings 7 that are used for protective cable, like this, bearing 7 circularizes and is distributed in the end that cable passes through steel pipe, no matter where cable is from all contacting with bearing 7 to passing through steel pipe, so just avoided cable to be worn and torn by the steel pipe port, on the other hand, owing to being subjected to the frictional force effect when cable passes through, bearing 7 rotates, and more laborsaving when the pulling cable passes through length apart from steel pipe.For preventing that bearing 7 from blocking, collide and making its even distribution mutually, between adjacent two bearings 7, be provided with stop nut 6 on the protective ring 5.In practice, for making things convenient for passing through of cable, the radius of protective ring 5 is not less than the radius of described steel pipe.
Axial direction is provided with equally distributed a plurality of strutting piece 4 between protective ring 5 and the clip 1, and is fixed together by strutting piece 4.Wherein, strutting piece 4 is made by reinforcing bar, between protective ring 5 and the strutting piece 4, and is between strutting piece 4 and the clip 1 and is welded to connect.In the present embodiment, the number of strutting piece is four, and is evenly distributed on the described protective ring 5.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection range of technical solutions of the utility model.
