Abstract
The utility model relates to an underground cable tube inserting device, which is composed of a helical spring, rope hooks arranged on both ends of the helical spring and external force connecting nuts; wherein the rope hooks and the helical spring are integrated; the external force connecting nuts are welded with the helical spring; the multi-section connection can be adopted for the helical spring; the connecting nuts and connecting bolts which are welded with the helical spring into a whole are respectively arranged at the two ends of the connections; the external force bolts can be hand-operated screw bolts or electric drill bolts. One end of the helical spring with the rope hook is extended into a bent pre-buried tube; the electric drill is powered on and appropriate axial pushing force is applied, then the helical spring passes through the bent tube, and after the cable is hung on the spring and appropriate axial pushing force is applied; the cable can be inserted into the pre-buried tube. The underground cable tube inserting device has the advantages that the structure is simple; the device can be freely extended and drawn back in the bent tube; the hanging is firm; the hanging speed is high; the work efficiency is high, and the inserting difficulty of cables in underground cable tubes is solved.
Description
Technical field
The utility model is a kind of cable underground pipe thread guide devices
Background technology
In various ground and underground construction, often want pre-buried various electric power, communication cables, for protecting these cables, people use plastic tube to wear as the cable pipe.Tend to run into crooked situation when wearing cable again, cable also must be followed bending, connects the pre-buried cable pipe of cable by bending and has just become a difficult problem.Present way is manually to connect, and wastes time and energy, and work efficiency is very low.Therefore, people urgently wish to research and develop the novel lead wire device and solve this problem.
Summary of the invention
The purpose of this utility model proposes a kind of cable underground pipe thread guide devices exactly, to solve the existing problem that work efficiency is low, cost is high that manually connects.
This cable underground pipe thread guide devices that the utility model proposes is characterized in that it is made up of the line hook and the external force attaching nut at helical spring, helical spring two ends, and line hook and helical spring are consubstantialities, and external force attaching nut and helical spring are welding.
Helical spring can connect for multistage, and the two ends, junction have attaching nut and the connecting bolt that is welded as a whole with helical spring respectively.
Locked screw is arranged on attaching nut and the connecting bolt, locked screw is housed.
Locked screw is arranged on the external force attaching nut,, unclamp during with the prevention reverse rotation when the external force nut is connected the locked screw of fashionable dress with the external force screw rod.
The external force screw rod can be the screw rod of shaking the hand, and also can be the electric drill screw rod.
External force screw rod and external force attaching nut can use with the syndeton of sleeve bulb and lamp socket and replace.
Every section helical spring length is 0.2-3m.
Cable of the present utility model connects function and is based on that the certain elasticity of flexure of helical spring and intensity realizes, it can reach the other end by the end from the pre-pipe laying of bending in the elastic force scope, as shuttle cable is worn again and moved in the crooked pre-pipe laying.During use, the external force screw rod that is clamped on the electric drill is tightened on the external force attaching nut, goes up locked screw in case of necessity again, it can not be unclamped.One end helical spring of strip line hook is stretched into crooked pre-pipe laying, start electric drill and apply suitable axial thrust, whole helical spring will enter gradually, be penetrated into the other end of bend pipe, close electric drill, hang up cable, start electric drill again and impose suitable pulling force, helical spring withdraws from, and cable is just connected in the pre-pipe laying.Shake the hand or the external force screw rod of T font with band, push away or revolve with hand-screw and draw helical spring also can play same effect.
If pre-buried bend pipe is long, the multistage helical spring can be coupled together use.
The utility model is simple in structure, and is free to advance or retreat in swan-neck, and firm to the hook of cable, speed is fast, and the work efficiency height has solved the difficult problem that present cable underground pipe cable connects.
Description of drawings
Accompanying drawing 1 is the front view of the present utility model (state in curved tube the time.Omission is cutd open by office).
Accompanying drawing 2 is buckle helical spring, attaching nut and the integrated front view of locked screw.
Accompanying drawing 3 is external force screw rod front views.
Accompanying drawing 4 is rear helical spring, connecting bolt and the integrated front view of external force attaching nut.
Accompanying drawing 5 is that the external force screw rod front view of shaking the hand is arranged.
Among the accompanying drawing 1-5, each parts label is as follows:
The 1-helical spring; 2-attaching nut; The locked screw of 3-; 4-attaching nut; The underground preburied bend pipe of 5-; 6-external force attaching nut; 7-external force screw rod; 8-shakes the hand.
Embodiment
Shown in Fig. 1-5.The helical spring (1) that is uneven in length to 3m with 20cm welds with attaching nut (2), the stretching line hook of pulling back of the other end, with interior pre-pipe laying, one section helical spring just can meet the demands for length 3m, and external force screw rod (7) can directly tighten on the attaching nut and operate.For pre-buried length of tube more than 3m bend pipe, couple together and could adapt to the multistage helical spring.First section back can end to end one-tenth multistage, and since second section, every section head and the tail two ends are welded to connect nut and connecting bolt (4) respectively, and the attaching nut of the tail end of the last section is external force attaching nut (6).All have screw on attaching nut and the connecting bolt, in order to locked screw (3) to be installed.External force screw rod (7) is a screw rod that has straight-bar, the T font of screw thread or shake the hand (8) are arranged, and the attaching nut is connected with external force, so that the power of precession or back-out is provided to helical spring.During for straight-bar, only need be clamped in it on electric drill and get final product.Adopt manual operations during for other shapes.For easy to connect, between each section helical spring, the external force screw rod replaces with the structure that can adopt with plug bush type bulb and lamp socket that connects between the external force attaching nut.
The parts that this example is not mentioned as mentioned above.
The thread guide devices of making so generally has 1-5 section helical spring, a straight screw rod and a little electric drill, and the pre-pipe laying that runs into different length and camber just can meet the demands.
