Abstract
The invention relates to a plastic pipe cutter. The upper end of a cutting head is fixedly provided with a lifting lug, the lower end of the cutting head is provided with a conical head, and the middle part of the cutting head is provided with an upper groove and a lower groove; the upper groove and the lower groove are staggered in the circumferential direction of the cutting head; an upper cutter and a lower cutter are respectively hinged in the upper groove and the lower groove through an upper hinge shaft and a lower hinge shaft; the incisions of the upper cutter and the lower cutter are formed above; an upper torsional spring and a lower torsional spring are respectively arranged between the upper and lower cutters and the upper and lower hinge shafts; when no external force exists, the incisions of the upper cutter and the lower cutter are exposed out of the cutting head. According to the plastic pipe cutter, the structure is simple, the use is convenient, and a frozen plastic liquid supply tube of a mine can be recovered smoothly.
Description
Technical field
The present invention relates to a kind of cutting tool of plastic tube, mine freezes to be difficult in frigo the cutting tool of the plastics feed pipe of recovery.
Background technology
In mine frozen construction process, frigo is the device that frozen construction must be used.Frigo is comprised of seamless steel pipe and plastics feed pipe etc.Hypothermic saline is transported to freezing pipe bottom by feed pipe and from feed pipe and seamless steel pipe annular space, returns, completes a circulation of freezing Cooling capacity exchanging.Generally after finishing, all salt solution in feed pipe in freezing pipe and pipe can be reclaimed pit shaft freezing; but in feed pipe removal process, often can run into feed pipe and be hampered, be difficult to extract or can only upluging part; this has not only improved construction cost, causes trouble also to later stage pit shaft slip casting simultaneously.By analyzing, cause feed pipe to rise pulling out difficult reason mainly containing following several respects: 1. freezing pipe inner salt water crystallization, has increased feed pipe and risen and pull out resistance; 2. in freezing pipe, precipitation has buried counterweight or part feed pipe, causes feed pipe to be difficult to pull out; 3. because formation displacement causes freezing pipe distortion, cause feed pipe to be stuck etc. rising to pull out to distortion place.Unrenewable like this feed pipe not only makes frozen construction cost increase, and may cause difficulty to the construction of pit shaft bottom simultaneously.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of plastic tube cutting tool, it is simple in structure, easy to use, can smoothly mine be freezed to plastics feed pipe and reclaim.
The present invention solves the technical scheme that its technical problem takes: the upper end of cutting head is hanger fixedly, lower end is conical head, there is upper and lower groove at middle part, upper and lower groove staggers at the circumferencial direction of cutting head, in upper and lower groove, respectively by the hinged upper and lower cutting knife of upper and lower hinge, the edge of a knife of upper and lower cutting knife, upper, has respectively upper and lower button spring between upper and lower cutting knife and upper and lower hinge, during without external force, the edge of a knife of upper and lower cutting knife spills cutting head.
The present invention is simple in structure, easy to use, can smoothly mine be freezed to plastics feed pipe and reclaim.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this present invention is further illustrated.
Fig. 1 is front view of the present invention;
Fig. 2 is left view of the present invention.
The specific embodiment
As shown in Figure 1, 2, the upper end of cutting head 2 is hanger 1 fixedly, lower end is conical head 11, there is upper and lower groove 3,7 at middle part, and upper and lower groove 3,7 circumferencial directions at cutting head 2 stagger, and upper and lower groove 3,7 is interior respectively by the hinged upper and lower cutting knife 4,8 of upper and lower hinge 6,10, the edge of a knife of upper and lower cutting knife 4,8 is upper, between upper and lower cutting knife 4,8 and upper and lower hinge 6,10, have respectively upper and lower button spring 5,9, during without external force, the edge of a knife of upper and lower cutting knife 4,8 spills cutting head 2.
Described upper cutter 4 has two, is arranged symmetrically with.
Described lower cutter 8 has two, is arranged symmetrically with.
Described upper and lower groove 3,7 circumferencial directions at cutting head 2 90 degree that stagger.
Described cutting head 2 is steel cylindrical tube.
