Description

Coiling dolly

Technical field

The utility model relates to a kind of take-up and pay-off device, specifically coiling dolly.

Background technology

Earth loop impedance test is the important tests project checking that whether earth system is good.During earth loop impedance test, need to place pressure-wire and each one of current line in substation foreign minister distance, length is 3-4 times of substation's catercorner length, single about needs 2000 meters during 500kV substation grounding testing impedance, for meet test accuracy again needs pass through larger current, this just needs thicker copper testing wire, and be example by 2000 rice noodles dishes, weight is more than 6 kilograms.Simple dependence manpower is lifted drum and is moved and carry out retractable cable and very require great effort.And if do not controlled the position of testing wire and direction during take-up, testing wire can be caused to concentrate in a large number and be wrapped in winding roller somewhere, both irregular also not consolidation, easily tied a knot during unwrapping wire.Tradition cord reeling method be manpower controlling party to, take-up efficiency is low.

Utility model content

For solving the problem, the purpose of this utility model is to provide a kind of coiling dolly, makes it both can realize automatic deploying and retracting testing wire, testing wire can be made again to be wound around evenly neat during take-up.

The utility model for achieving the above object, be achieved through the following technical solutions: coiling dolly, comprise base, mounting knob on base, before and after base lower end, both sides install a pair cardan wheel and a pair bull wheel respectively, first rotating shaft is installed between a pair bull wheel, first rotating shaft is installed the first gear, base is installed the first bracing frame, first bracing frame is installed the second rotating shaft, second rotating shaft fixedly mounts the second gear, first gear installs chain with the second gear coordinates, second rotating shaft also fixedly mounts winding roller, winding roller is wound around testing wire, base is installed the second bracing frame, second bracing frame is installed slide rail and leading screw, one end of leading screw connects motor, motor provides power for leading screw, slide rail is equipped with slide block, slide block installs Connection Block, Connection Block lower end mounting nuts, nut coordinates with leading screw, Connection Block installs contiguous block, contiguous block offers through hole, the free end of testing wire passes through hole.

For realizing the purpose of this utility model further, can also by the following technical solutions: described base installs the 3rd bracing frame, the 3rd rotating shaft installed by the 3rd bracing frame, the 3rd rotating shaft fixedly mounts the 3rd gear, the 3rd gear and chain interoperation; Guiding roller is installed in 3rd rotating shaft, and the free end of testing wire is walked around guiding roller lower end and touches with guiding roller; Power-transfer clutch is installed in the first described rotating shaft, and power-transfer clutch coordinates with the first gear, the pressing plate of power-transfer clutch connects one end of pipe link, the lower end of the hinged joystick of the other end of pipe link, and bottom and the base of joystick are hinged, and the upper end of joystick is positioned at handle side; The first described gear is identical with the second gear diameter, and winding roller is identical with large wheel diameter.

The utility model has the advantage of: in the utility model, by Manual-pushing handle, in traveling process, bull wheel wheel shaft rotates, and by gear and the forward and reverse rotation of chain-driving winding roller, reaches the object of automatic deploying and retracting line.In addition, in take-up process, motor drives contiguous block repeatedly to move on slide rail by screw-nut body, thus it is evenly neat that testing wire is wound around on winding roller.The utility model also has advantage compact, cheap for manufacturing cost and easy to use simple for structure.

Detailed description of the invention

Coiling dolly, as shown in Figure 1, comprises base 1, mounting knob 2 on base 1.Before and after base 1 lower end, both sides install a pair cardan wheel 3 and a pair bull wheel 4 respectively, install in the first rotating shaft 5, first rotating shaft 5 and install the first gear 6 between a pair bull wheel 4.Base 1 is installed the first bracing frame 7, first bracing frame 7 installs and the second rotating shaft 9, second rotating shaft 9 fixedly mounts the second gear 10, first gear 6 with the second gear 10 coordinates chain 11 is installed.Chain and gear also can arrange a set of in base 1 left and right sides respectively, to ensure that transmission is accurate.Second rotating shaft 9 also fixedly mounts winding roller 12, winding roller 12 is wound around testing wire 13.Base 1 is installed the second bracing frame 14, second bracing frame 14 is installed slide rail 15 and leading screw 16, one end of leading screw 16 connects motor 22, motor 22 provides power for leading screw 16, slide rail 15 is equipped with slide block 17, slide block 17 is installed Connection Block 18, Connection Block 18 lower end mounting nuts 19, nut 19 coordinates with leading screw 16.Connection Block 18 is installed contiguous block 20, contiguous block 20 is offered through hole 21, the free end of testing wire 13 passes through hole 21.This structure is by Manual-pushing handle 2, and the first rotating shaft 5 in traveling process on bull wheel 4 is rotated, and drives the forward and reverse rotation of winding roller 12 by the first gear 6, second gear 10 and chain 11, reaches the object of automatic deploying and retracting testing wire 13.In addition, in take-up process, motor 22 drives contiguous block 20 repeatedly to move on slide rail 15 by leading screw 16 and nut 19, thus it is evenly neat that testing wire 13 is wound around on winding roller 12.

During unwrapping wire, pull handle 2, makes bull wheel 4 rotate forward, and by wheel chain transmission, winding roller 12 is rotated forward, and open motor 22 and make motor 22 rotating repeatedly, contiguous block 20 is repeatedly moved on slide rail 15, and testing wire 13 realizes unwrapping wire with the movement of bull wheel 4.During take-up, promote handle 2, bull wheel 4 is reversed, by wheel chain transmission, winding roller 12 is reversed, opens motor 22 and make motor 22 rotating repeatedly, contiguous block 20 is repeatedly moved on slide rail 15, make testing wire 13 uniform winding on winding roller 12, testing wire 13 realizes take-up with the movement of bull wheel 4.

For when making take-up, testing wire 13 is wound around consolidation, described base 1 is installed and fixed installation the 3rd gear the 24, three gear 24 in the 3rd rotating shaft the 23, three rotating shaft 23 installed by the 3rd bracing frame the 8, three bracing frame 8 coordinates with chain 11; Guiding roller 28 is installed in 3rd rotating shaft 23, and the free end of testing wire 13 is walked around guiding roller 28 lower end and is touched with guiding roller 28.This structure makes can tighten during testing wire 13 take-up, to reach the object making testing wire 13 be wound around consolidation.

Carrying when conveniently the utility model does not work, power-transfer clutch 25 is installed in the first described rotating shaft 5, power-transfer clutch 25 coordinates with the first gear 6, the pressing plate of power-transfer clutch 25 connects one end of pipe link 26, the lower end of the hinged joystick 27 of the other end of pipe link 26, bottom and the base 1 of joystick 27 are hinged, and the upper end of joystick 27 is positioned at handle 2 side.When this structure can make bull wheel 4 rotate, the first gear 6 dallies, thus avoids winding roller 12 to rotate with bull wheel 4 and rotate, and prevents testing wire 13 unwrapping wire when carrying the utility model.

In order to make the rotating speed of the rotating speed of bull wheel 4 and winding roller 12 equal, the first described gear 6 is identical with the second gear 10 diameter, and winding roller 12 is identical with bull wheel 4 diameter.This structure makes the moving velocity of bull wheel 4 consistent with the folding and unfolding speed of testing wire 13, the convenient situation looking after testing wire 13 while retractable cable, and makes suitable adjustment and clearing of obstruction at any time, relay testing line 13.

The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The technology contents of the not detailed description of the utility model is known technology.
