The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
A kind of earthing megohm meter lead-in wire spooler is as the special-purpose spooler use of earthing megohm meter lead-in wire, the lead-in wire of folding and unfolding quickly and easily.Mainly comprise framework 1, main shaft 5, line wheel I 2 and line wheel II 3, as depicted in figs. 1 and 2.Framework 1 comprises two root posts that be arranged in parallel, and by a cross bar captive joint, the lower end of column is pointed respectively at the two ends up and down of two root posts, is convenient to the earthing megohm meter down-lead device is inserted in soil.The middle part of column is provided with the main shaft 5 of taking turns I 2 and line wheel II 3 for position line by bearing I 7-1, line wheel I 2 is arranged on main shaft 5 by bearing II 7-2 by key pin 6, line wheel II 3.The line wheel arranged outside of main shaft 5 has rocking handle 10, by rocking handle, main shaft 5 is rotated.
Line wheel I 2 is taken turns on the relative two sides wheel disc of II 3 with line and is provided with clamping apparatus 8, as shown in Figure 3.Gear 8-1 is coaxial fixing with line wheel I 2, and latch 8-2 passes through can change the clutch state of clamping apparatus 8 by stirring connecting rod 8-4, thereby make two line wheels separate or connect on support 8-3 and the fixing online wheel II 3 of connecting rod 8-4.The race of line wheel I 2 and line wheel II 3 is designed to the font to line wheel central concave V, and the wheel trench bottom of online wheel is provided with connection terminal 4.
Be provided with cord grip 9 on column, wherein baffle plate 9-1 is captiveed joint with column, have elliptical aperture on baffle plate 9-1, the edge of the online wheel in its center of circle, can hang up tension spring 9-2 by elliptical aperture, the free end of two tension springs connects by metal filament 9-3, and the outer surface cover of metal filament 9-3 has two line ball pipe 9-4 that lay respectively at line wheel I 2 and line wheel II 3 outers.
Can first the lower end of framework 1 column be inserted in soil when using earthing megohm meter down-lead device spooler, when carrying out the take-up of earthing megohm meter lead-in wire, at first two lead-in wires with earthing megohm meter connect on the connection terminal 4 of online wheel I 2 and line wheel II 3, wherein, current feed (long line) connects on the connection terminal 4 of online wheel I 2, and current potential lead-in wire (short-term) connects on the connection terminal 4 of online wheel II 3.Stirring connecting rod 8-4 connects clamping apparatus 8, line wheel I 2 and line wheel II 3 connects together and synchronizes rotation with main shaft 5, due to retracing spring 8-5 being housed in support 8-3, clamping apparatus 8 keeps current state always, and rotation crank 10 band moving-wire wheel I 2 and line wheel II 3 are with two lead-in wire while separate collections.The race of taking turns I 2 and line wheel II 3 due to line is in the shape of the letter V, and can guarantee that a circle that goes between is pressed on connection terminal 4.Stirring latch 8-2 when current potential lead-in wire (short-term) is received unclamps clamping apparatus 8, line wheel I 2 is separated with line wheel II 3, line wheel II 3 is separated with main shaft 5, rotation crank 10 band moving-wire wheel I 2 are collected remaining current feed (long line), until electric current (long line) lead-in wire is received the position.In the take-up process, lead-in wire can be compressed by cord grip 9, lead-in wire is wound around is difficult for loose ring, neat appearance.
When carrying out earthing megohm meter lead-in wire unwrapping wire, at first stirring latch 8-2 unclamps clamping apparatus 8, pull simultaneously two lead-in wires to carry out unwrapping wire, because line wheel I 2 is separated with line wheel II 3, two lead-in wire unwrapping wire are independent of each other, line wheel II 3 stops when current potential lead-in wire is put into, pulls on streaming current lead-in wire band moving-wire wheel I 2 and main shaft 5 and rotates until discharge.Because the first lap that goes between when the take-up is pressed on terminal, lead-in wire all must be put and just can be exposed connection terminal 4 and carry out line with earthing megohm meter or equipment under test, realized that in earthing megohm meter lead-in wire operating specification, lead-in wire must be decontroled the requirement of arriving designated length, effectively standard the grounding resistance measurement work of earthing megohm meter, for the ground connection lightning protection of equipment under test provides result of a measurement accurately.
