Abstract
The invention relates to an auxiliary device for replacing a cable in a threading pipe. The auxiliary device comprises a traction head (1) and clamping pipes (3) fixedly arranged at the two ends of the traction head (1). The outer diameter of the clamping pipes (3) is gradually reduced from the end face of the traction head (1) outwards, taper threads and fastening nuts (5) matched with the taper threads are arranged on the external circles of the clamping pipes (3), and two to four openings (6) extending towards the large-diameter ends in the diameter direction are formed in the small-diameter ends of the clamping pipes (3). According to the auxiliary device, operators can conveniently replace the cable in the threading pipe in a labor saving mode, and work efficiency is improved.
Description
Technical field
The present invention relates to Electric Wires ＆ Cables mounting and installation technical field, it particularly relates in a kind of penetration pipe, change cable
Auxiliary device and cable replacing options.
Background technology
Cable penetration pipe primarily serves the effect of protection cable, is usually used in the hidden of Electric Wires ＆ Cables and lays, in bad environments
Heavy industry operation field, cable penetration pipe be even more possesses dust-proof, the function such as waterproof.
Existing penetration pipe, in replacing is managed during Electric Wires ＆ Cables, joint is made with new cable one end in old cable one end, so
Butt joint carries out waterproof wrapping afterwards, pulls old cable, takes new cable out of using old cable, completes to change.Whole process occurs
A lot of problems, the width for making joint is less than threading caliber, needs operating personnel more to waste time and energy；Joint be can not play well, and pull
During easily get loose, secondary must do over again, affect threading efficiency.
Content of the invention
The present invention is directed to the deficiencies in the prior art, provides in a kind of penetration pipe and changes cable auxiliary device, can make operation people
Member changes cable convenient and strength-savingly in penetration pipe, improves work efficiency.
The present invention is achieved through the following technical solutions, provides in a kind of penetration pipe and changes cable auxiliary device, including
Drawing head and the clamping pipe for being fixedly arranged on the drawing head two ends, outside the clamping pipe, drawing head end face is outwards gradually reduced without leave,
The cylindrical clamp nut for being provided with taper thread and being adapted to the taper thread of clamping pipe, clamping pipe miner diameter end is provided through directly
Footpath direction and the opening for extending to bigger diameter end, one end of new, old cable is worn respectively to two clamping pipes, and solid with clamp nut
Fixed, new cable movement being driven by pulling old cable, while extracting out old cable from penetration pipe, completes wearing for new cable
Pipe.
As optimization, on the drawing head outer wall, at least three back-up roller wheels are evenly arranged with along circumferential direction, reduction is led
Frictional force between leader and threading inside pipe wall, is that cable replacing is more laborsaving, saves time.
As optimization, fixed matcoveredn on the clamping inside pipe wall, it is to avoid cable is clamped inside pipe wall damage.
Penetration pipe inner cable replacing options, are carried out in accordance with the following steps：
A, two clamp nut positions of adjustment, make two clamping pipes in the raw；
B, one end of old cable is worn to one of clamping pipe, and is fastened with fastening bolt, by one end of new cable wear to
In another clamping pipe, equally fastened using fastening bolt；
C, the other end of pulling old cable, until new cable exposes from penetration pipe；
D, unscrew two clamp nuts, new, old cable is extracted out from clamping pipe.
Beneficial effects of the present invention are：While having enough clamping effect when ensureing and applying pull strength to new cable,
The end of protection clamping cable；The design of roller, that is, reduce the friction of device and penetration pipe, extends the use longevity of itself
Life, reduces resistance of the cable in penetration pipe again, improves work efficiency.

Specific embodiment
For the technical characterstic of this programme clearly can be described, below by specific embodiment, this programme is illustrated.
Cable auxiliary device being changed in a kind of penetration pipe as shown in Figure 1, including drawing head 1 and is fixedly arranged on 1 two ends of drawing head
Clamping pipe 3, outer 1 end face of drawing head without leave of clamping pipe 3 is outwards gradually reduced, clamping pipe 3 is cylindrical be provided with taper thread and with
The clamp nut 5 of taper thread adaptation, clamps 3 miner diameter end of pipe and is provided through diametric(al) and two to four extended to bigger diameter end
Opening 6, the present embodiment split shed 6 is four, and the tube wall of clamping pipe 3 is equally divided into four parts.
For reducing the frictional force between drawing head 1 and threading inside pipe wall, uniformly set along circumferential direction on 1 outer wall of drawing head
At least three back-up roller wheels 2 are equipped with, in the present embodiment, the quantity of back-up roller wheel 2 is that four so that drawing head is on four direction
All there is the back-up roller wheel that can roll along threading inside pipe wall.
For avoiding cable that inside pipe wall damage is clamped, protective layer 4 is fixedly provided with clamping 3 inwall of pipe, in the present embodiment
Protective layer 4 adopts quality of rubber materials, can not only prevent cable from being crushed, and its cost is relatively low.
Using when in the present embodiment, replacing cable auxiliary device carries out cable replacing, carry out as follows：
A, two clamp nut positions of adjustment, make two clamping pipes be in naturalness；
B, one end of old cable is worn to one of clamping pipe, and is fastened with fastening bolt, by one end of new cable wear to
In another clamping pipe, equally fastened using fastening bolt, due to the presence of opening, clamp effect of the tube wall in clamp nut
Lower to contract, so as to compress cable；
C, the other end of pulling old cable, old cable drives new cable to enter penetration pipe from one end by this auxiliary device, until
New cable exposes from the other end of penetration pipe；
D, unscrew two clamp nuts, new, old cable is extracted out from clamping pipe.
Certainly, described above is also not limited to the example above, the present invention without description technical characteristic can by or
Realized using prior art, will not be described here；Above example and accompanying drawing are merely to illustrate technical scheme not
It is limitation of the present invention, reference has preferred embodiment been described in detail to the present invention, the ordinary skill people of this area
Member it should be appreciated that those skilled in the art made in the essential scope of the present invention change, remodeling, interpolation
Or replace without departure from spirit of the invention, should also belong to the claims of the present invention.
