The conventional movable variable-frequency speed-adjusting device, of which a frequency converter and a wire coil are moved in an independent manner, has the defects that carrying is required twice, which is labor-consuming and toilsome; and a connector is required to be disconnected during the moving of the device, so that the connector is easily damaged due to long-term plugging in/pulling out of the connector. The integral movable variable-frequency speed-adjusting device provided by the utility model comprises a power cord and the frequency converter, and is characterized in that the power cord is wound on the wire coil; the wire coil and the frequency converter are arranged on the same movable stand; a plurality of rolling wheels are arranged below the movable stand; the wire coil comprises a wire coil bracket, a rotation plate, a conductive slip ring and a conductive element; the conductive slip ring is arranged on the rotation plate and electrically connected with the power cord; one end of the conductive element is in contact with the conductive slip ring; and the other end of the conductive element is connected with frequency converter. The utility model has the advantages that as the frequency converter and the wire coil are arranged on the same movable stand and can be moved together, the time is saved; and as the overhanging length of the power cord can be increased as long as the distance is increased, the industrial connector on the wire coil is not required to be plugged in or pulled out, which not only facilitates the use, but also effectively protects the industrial connector.
Description
[technical field]
The utility model relates to a kind of portable RHVC.
[background technology]
The dither motor frequency converter speed regulating device is mainly used in the concrete prefabricated element construction of high-speed railway, highway, highway bridge, engineering construction at present.The motor of the branch control cabinet of many parallel connections that one cover dither motor frequency converter speed regulating device comprises a frequency converter, be connected with frequency converter, many parallel connections that are connected with branch control cabinet.All motors move simultaneously or stop simultaneously on concrete prefabricated mould of every branch control cabinet control, and each concrete prefabricated mould has 6～9 motors approximately.This kind method fixes circuit earlier, and installation period is long for the first time.As long as the button of handoff leg control cubicle can select to move mould, do not need installation when using having after, advantage such as save time still, has following shortcoming:
1, a production line has more than 100 meter, and circuit is long, and the cost of lead is than higher.
2, frequency converter is when operation, inverter output terminal is because distributed capacitance and distributed inductance existence, because circuit is long, the distributed capacitance and the distributed inductance that exist can not be ignored, du/dt and di/dt exist, and have caused motor side to have that very high voltage and inverter output terminal electric current are very big, need the withstand voltage index of corresponding raising motor and increase frequency converter type selecting power, improve motor and frequency converter cost, increase system cost.
3, because each branch road cabinet all needs to install electric motor protective device, the whole system cost obviously improves.
For solving the long problem of frequency converter and branch control cabinet circuit, adopt portable vibrating motor RHVC, when needs one branch control cabinet is worked, frequency converter is moved near this branch control cabinet, shorten distance between the two, reduce line length, but bring following problem thus:
1, frequency converter and drum separate and move, and need carrying twice, waste time and energy;
2, when frequency converter moves, need disconnect the industrial connector that is connected between frequency converter and the drum so that both moving respectively plugs industrial connector for a long time, cause the damage of industrial connector easily.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, and provides a kind of one portable RHVC, moves to reach conveniently, reduces cost, the purpose of protection device.For this reason, the utility model is taked following technical scheme:
The portable RHVC of one, comprise power line and frequency converter that an end can be electrically connected with the city, it is characterized in that: described power line is wound on the drum, and described drum and frequency converter are with being located on the movable stand, and described movable stand below is provided with a plurality of scroll wheels; Described drum comprises the drum support that is fixed in movable stand, the rolling disc that is rotationally connected with the drum support, is located at the conducting slip ring that is electrically connected with power line on the rolling disc, the electric-conductor that an end touches with conducting slip ring and the other end is connected with frequency converter.Because frequency converter and the drum that is wound with power line all are positioned on the same movable stand; do not need frequency converter and drum are separately moved; convenient moving; and save time; because power line can be with the elongated extension that increases power line of distance, and length is regulated automatically, the setting of conducting slip ring can link to each other power line all the time with the power input of frequency converter simultaneously; need not variation because of distance and constantly plug industrial connector on the drum, effectively protected industrial connector the time easy to use.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described scroll wheel comprises universal wheel and is positioned at the directional wheel at universal wheel rear.Convenient moving.
Described drum support is connected by rotation axis with rolling disc, and described conducting slip ring is provided with rotation axis is concentric.Conducting slip ring and electric-conductor are touched all the time, avoid influencing between the two connection because of rocking of conducting slip ring.
Described power line is realized being electrically connected of power line and conducting slip ring by a conducting strip that touches with conducting slip ring.Conducting strip is electrically connected with electric-conductor by conducting slip ring, and in the drum rotating process, the relative position of conducting slip ring and electric-conductor is constant, for the reliability that raising touches, can establish hold down gag on electric-conductor, conducting strip, such as spring etc.
Beneficial effect: because frequency converter and the drum that is wound with power line all are positioned on the same movable stand; do not need frequency converter and drum are separately moved; convenient moving; and save time; simultaneously because power line can be with the elongated extension that increases power line of distance; length is regulated automatically; the setting of conducting slip ring can link to each other power line all the time with the power input of frequency converter;, effectively do not protected industrial connector the time easy to use because of the variation of distance constantly plugs industrial connector on the drum.
