Abstract
The invention discloses a ratchet wheel electric wire cutter. Therefore, aerial cables can be cut through ground operations. The ratchet wheel electric wire cutter comprises a supporting bar, a fixed cutter connecting head, an inverted-U-shaped hook, a fixed cutter, a movable cutter, a movable cutter connecting handle, a top-end stranded wire, a stranded wire turning sleeve, a middle-end stranded wire, a tail-end stranded wire, a fixing sleeve and a ratchet wheel operating rod. The ratchet wheel operating rod is pressed downwards, the tail-end stranded wire is tightened continuously, then the middle-end stranded wire and the top-end stranded wire are pulled downwards, the movable cutter which is fixed on a movable cutter connecting head is pulled by the top-end stranded wire to make counterclockwise rotation to be closed with the fixed cutter, and the cables are cut ultimately.
Description
Technical field
The invention belongs to a kind of cable cutting knife, be specifically related to a kind of thorn wheel electric cable cutter.
Background technology
In conventional electric power circuit upkeep operation, high-altitude cable cutting adopts cat ladder mode or lift lift-off more, in high vacancy, uses pliers or cable cutting knife to carry out rupturing operation to cable, and danger is higher, operation trouble.For this problem, the invention provides a kind of a kind of electric cable cutter that can cut at Chu Dui high-altitude, ground cable.
Summary of the invention
A kind of ratchet electric cable cutter comprises: support stick, stationary knife connector, inverted U-shaped hook, stationary knife, moving knife, moving knife connection handle, top twisted wire, twisted wire break-in cover, middle-end twisted wire, tail end twisted wire, fixed cover, ratchet action bars, described support stick is the club shaped structure that insulating materials is made, support stick top connects uses stationary knife connector, described stationary knife connects first side and is provided with inverted U-shaped hook, U-shaped barb is convenient to hook other cable when to cable cutting and as support, is convenient to operation and carries out, described stationary knife connector top is fixed with stationary knife, described stationary knife and moving knife are bolted and are scissor-shaped, described stationary knife and moving knife profile are hook-type and are convenient to bite the not landing of cable that will cut, described moving knife tail end is connected and fixes with power connection handle, described moving knife connection handle is connected with twisted wire upper end, top, soft whipping wire lower end, described top is connected with twisted wire break-in cover, described twisted wire break-in is set on supporting rod first half position, described twisted wire break-in cover lower left is connected with middle-end twisted wire upper end, described middle-end twisted wire lower end is connected with tail end twisted wire upper end, described tail end twisted wire lower end is connected with fixed cover, described fixed cover is fixed on support stick, on described fixed cover, be provided with ratchet action bars, described ratchet action bars and tail end twisted wire are gear-like occlusal contact condition.
The present invention further improves and is: described twisted wire break-in cover side is square, upper and lower two angles, twisted wire break-in cover left side connect respectively top twisted wire and middle-end twisted wire, Liang Ge angle, right side and middle part, left side are provided with pulley, when tightening up twisted wire, twisted wire break-in wheel is along support stick down sliding, when unclamping twisted wire, twisted wire break-in is taken turns along support stick upward sliding, and the setting of pulley effectively reduces the friction between twisted wire break-in wheel and support stick.
The present invention further improves and is: described middle-end twisted wire is parallel with support stick with tail end twisted wire, and when tightening up twisted wire, ratchet action bars can be bitten the gear structure on tail end twisted wire smoothly.
The present invention further improves and is: described tail end twisted wire bottom is L-shaped, avoids tail end twisted wire when moving knife is opened to skid off fixed cover.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention, wherein: 1-support stick, 2-stationary knife connector, the inverted U-shaped hook of 3-, 4-stationary knife, 5-moving knife, 6-moving knife connection handle, 7-top twisted wire, 8-twisted wire break-in cover, 9-middle-end twisted wire, 10-tail end twisted wire, 11-fixed cover, 12-ratchet action bars.
The specific embodiment
A kind of ratchet electric cable cutter, as shown in Figure 1, comprise support stick 1, support stick 1 top is provided with stationary knife connector 2, stationary knife connector 2 is provided with inverted U-shaped hook near the position of support stick, can when cutting off high cable, hook other cable as the strong point, on stationary knife connector 2, be fixed with hook-shaped stationary knife 3, stationary knife 3 connects into scissor-shaped by bolt and moving knife 4, moving knife 4 tail ends are provided with moving knife connection handle 6 for connecting top twisted wire 7, top, top twisted wire 7 tail ends are fixed on twisted wire break-in cover 8, twisted wire break-in is overlapped 8 sides and is square, Liang Ge angle, right side and left side intermediate member are provided with pulley, twisted wire break-in cover 8 can be slided up and down on support stick 1, the tail end that 8 upper left corners are connected with top twisted wire 7 is overlapped in twisted wire break-in, the lower right corner is connected with middle-end twisted wire 9, the lower end of middle-end twisted wire 9 is connected with tail end twisted wire 10 upper ends, tail end twisted wire 10 lower ends are connected with fixed cover 11, middle-end twisted wire 9 is parallel with support stick 1 with tail end twisted wire 10, fixed cover 11 is fixed on support stick 1 irremovable, on fixed cover 11, be provided with ratchet action bars 12, ratchet action bars 12 is gear-like occlusal contact condition with tail end twisted wire 11.
When pressing down ratchet action bars 12, tail end twisted wire 10 is produced to downward pulling force, tail end twisted wire 10 drives middle-end twisted wire 9 to move down, the twisted wire break-in cover 8 being connected with middle-end twisted wire 9 is along support stick 1 down sliding, drive top twisted wire 7 to move down simultaneously, top twisted wire 7 pulls moving knife connection handle 6 to be rotated counterclockwise, the moving knife 5 being fixed on moving knife connection handle 6 is rotated counterclockwise and stationary knife 4 closures simultaneously, and then sting the cable tightly being hooked by stationary knife 4, along with constantly pressing down of ratchet action bars 12, moving knife 5 final with the completely closed power-off cable that twists of stationary knife 4.
