By applying the material placing frame with good heat radiation performance in the first aspect of the embodiment, when steel cables are placed, the material coil 310 can be placed on the rotating seat 180, then the cables are pulled to place wires, at this time, the material coil 310 can drive the rotating seat 180 to rotate, and the heat radiation fan 190 can also rotate under the driving of the rotating seat 180, so that the air flow of the rotating connection part of the first centering sleeve 140 and the base 100 is accelerated, and the heat radiation performance of the rotating connection part is enhanced; meanwhile, the heat dissipation fan 190 is driven by the rotating base 180 to rotate and stop, so that a power supply is not required to be separately arranged to drive the fan to rotate.
Wherein, the heat dissipation fan 190 can accelerate the air flow of the rotary connection part of the rotary seat 180 and the base 100 in various ways; for example, the air outlet side of the heat dissipation fan 190 faces the rotary connection part between the rotary seat 180 and the base 100, so that the wind blown by the heat dissipation fan 190 can take away the heat generated by the rotary connection part, thereby enhancing the heat dissipation performance; or the air inlet side of the heat dissipation fan 190 faces the rotary connection part of the rotary base 180 and the base 100, when the heat dissipation fan 190 rotates, the air in the rotary connection part is sucked into the air inlet side of the fan, so that the outside air enters, and the air flow rate of the rotary connection part can also be increased.
On the other hand, since the heat dissipation fan 190 is connected with the rotating seat 180, the heat dissipation fan 190 can also receive air resistance in the rotating process of the rotating seat 180, so that the rotating resistance of the rotating seat 180 is increased, and after the paying-off is completed, the heat dissipation fan 190 can help the rotating seat 180 to stop as soon as possible, thereby preventing the rotating seat 180 from idling for a long time under the inertia effect, and preventing the situations of field personnel injury and the like; meanwhile, as the fan rotates along with the rotating base 180, the fan can automatically stop when the rotating base 180 stops rotating, and the fan does not need to be controlled to rotate additionally.

Wherein, the blowing frame that heat dispersion is good still includes: a second centering sleeve 160 sleeved on the upper end of the main shaft 170; a support bar 150 connecting the second centering sleeve 160 and the rotating base 180; the centrifugal fan is positioned between the first centering sleeve 140 and the second centering sleeve 160, and the centrifugal fan is connected with the second centering sleeve 160; the first centering sleeve 140 and the second centering sleeve 160 can effectively prevent the rotating seat 180 from eccentrically rotating relative to the main shaft 170, which causes abrasion of the main shaft 170; in addition, the centrifugal fan is positioned between the first centering sleeve 140 and the second centering sleeve 160, so that the distance between the centrifugal fan and the second centering sleeve is closer, and the heat dissipation effect is enhanced.
Meanwhile, a connection sleeve may be disposed between the second centering sleeve 160 and the fan, so that the fan and the first centering sleeve 140 are not directly connected, and at this time, a yielding position may be provided for the reduction gear 200, thereby preventing the reduction gear 200 from interfering with the connection sleeve.
As shown in fig. 1, a plurality of support bars 150 are connected between the second centering sleeve 160 and the rotating base 180, and the plurality of support bars 150 are uniformly distributed along the circumferential direction of the main shaft 170; at this time, the support bar 150 may serve to support the material roll 310 while connecting the first and second centering sleeves 140 and 160.

The driving device can drive the speed reducing shaft 220 to move to abut against the main shaft 170 in various ways, for example, a motor drives the screw nut mechanism to operate, so as to drive the speed reducing shaft 220 to abut against the main shaft 170, or a linear motor directly drives the speed reducing shaft 220 to abut against the main shaft 170, etc.; at this time, since the motor is operated only when the reduction holder 210 needs to reduce the speed, the motor does not need to be continuously supplied with power, and thus, the motor can be supplied with power by a battery built in the rotation holder 180.
Further, as shown in fig. 2, in order to increase the friction area between the main shaft 170 and the speed reduction shaft 220, the main shaft 170 is prevented from being worn seriously locally, and the service life of the main shaft 170 is shortened; the speed reducing shaft 220 is connected with a V-shaped speed reducing plate 250, and the opening of the V-shaped speed reducing plate 250 faces the main shaft 170; when the speed reducing shaft 220 is close to the main shaft 170, two surfaces of the V-shaped opening of the V-shaped speed reducing plate can rub against the main shaft 170, and the friction area is effectively increased.
