Abstract
The utility model relates to a tube sawing unit, in particular to a hand-operated tube sawing unit. The hand-operated tube sawing unit comprises a fixed clamping mechanism, a connecting device and a cutting device, a clamp hoop is arranged on the fixed clamping mechanism, the outer diameter of a tube to be cut is fixed by the clamp hoop, the cutting mechanism is fixedly connected with the connecting device, one end of the connecting device is connected with the fixed clamping mechanism through a pin to enable a saw cutter main shaft of the cutting mechanism and a longitudinal axis of the tube to be cut to be parallel, and the cutting mechanism and the fixed clamping mechanism are of a straw copper shape; and a hand wheel is arranged on the connecting device, a saw cutter of the cutting mechanism is connected with the hand wheel through gears. The tube sawing unit has the advantages of being convenient to use and high in rush repair efficiency.
Description
Technical field
The utility model relates to a kind of saw pipe device, relates in particular to a kind of hand-rail type saw pipe device.
Background technology
During the gas pipe on-line emergency repair, because security reason does not allow to make to saw with a chainsaw pipe, therefore, current gas pipe on-line emergency repair is all to use handsaw saw pipe.While operating with handsaw, because tube wall is thicker, be difficult for sawed-off, saw a road junction usually the time of cost normally all want 30 minutes, cause like this saw pipe time long, and rush to repair the principle completed disagree within the minimum time.
The utility model content
The utility model provides a kind of hand-rail type saw pipe device, and it can improve the repairing efficiency of gas pipe greatly.
In order to achieve the above object, the utility model is achieved in that
A kind of hand-rail type saw pipe device, comprise: fixing and holding mechanism, jockey, cutting mechanism, described fixing and holding mechanism is provided with clip, the external diameter of the fixing pipe cutting to be cut of described clip, described cutting mechanism is fixedly connected on described jockey, one end of described jockey is connected in described fixing and holding mechanism by bearing pin, makes the saw cutter main shaft of described cutting mechanism parallel with the longitudinal axis of described pipe cutting to be cut, and described cutting mechanism becomes the chopper shape with described fixing and holding mechanism; Described jockey is provided with handwheel, and the saw cutter of described cutting mechanism is connected by gear with described handwheel.
As a kind of improvement, the other end of described jockey is provided with handle.
As a kind of improvement, the other end of described jockey connects and described fixing and holding mechanism by spring.
Can effectively the utility model be fixed in to pipe cutting to be cut by clip, with respect to using handsaw saw pipe, the utility model can not produce the problem that saw is askew when the saw pipe, has improved repairing efficiency; Shake handwheel, laborsaving while utilizing big or small gear-linked band cutting blade to reach work; Utilize spring pressure, under the saw cutter is automatic when the saw pipe, be absorbed in pipe.
The beneficial effects of the utility model have: easy to use, repairing efficiency is high.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of hand-rail type saw pipe device, comprise: fixing and holding mechanism 1, jockey 2, cutting mechanism 3, described fixing and holding mechanism 1 is provided with clip 11, the external diameter of described clip 11 fixing pipe cuttings to be cut, described cutting mechanism 3 is fixedly connected on described jockey 2, one end of described jockey 2 is connected in described fixing and holding mechanism 1 by bearing pin, make the saw cutter main shaft 31 of described cutting mechanism 3 parallel with the longitudinal axis of described pipe cutting to be cut, 1 one-tenth chopper shape of described cutting mechanism 3 and described fixing and holding mechanism; Described jockey 2 is provided with handwheel 22, and the saw cutter of described cutting mechanism 31 is connected by gear with described handwheel 22.
As a kind of improvement, the other end of described jockey 2 is provided with handle 21.
As a kind of improvement, the other end of described jockey 2 connects and described fixing and holding mechanism 1 by spring 4.
During use, hold handle, bindiny mechanism is opened, clip is placed in to pipe to be cut, fastening, decontrol handle; Then a hand wheel of starting, utilize spring pressure, under the saw cutter is automatic when the saw pipe, is absorbed in pipe; Then unclamp clip, will saw the pipe device and move with circular path, arrive not cutting part fastening clamp, swinging handle, cutting.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
