Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
In the present invention, the use of directional terms such as "upper, lower, left and right" in the absence of a contrary explanation generally refers to the orientation shown in the drawings. "inner and outer" refer to the inner and outer contours of the respective component itself.
As shown in fig. 1 and 2, the present invention provides a wire releasing device, which comprises a base 1, wherein the base 1 is provided with a roller 101 capable of moving along a rail, so that the wire releasing device can move; a support part 2 mounted on the base 1; pay off reel 3, pay off reel 3 rotatable install in supporting part 2 to make bear in cable on pay off reel 3 can follow pay off reel 3 rotates.
Through the technical scheme, when in paying off operation, the cable shaft is placed on the pay-off reel 3, the axis of the cable shaft is vertical to the pay-off reel 3, the cable can be moved and paid out by the rollers of the base 1, the rollers 101 can be matched with the rail, so that the paying-out device can move freely along the rail, because the placed cable can generate pulling force on the cable on the pay-off reel 3, the cable placed on the pay-off reel 3 can rotate together through the rotatable pay-off reel 3, the damage to the cable caused by friction generated by dragging of the cable during paying off is overcome, the operation is simple, the cable only needs to be fixed at the initial paying off position, because this pay-off's gyro wheel 101 and rail phase-match, consequently need not adjust the direction, only need promote this pay-off, can accomplish the unwrapping wire operation, single can operate, has saved manpower and materials.
Optionally, the supporting portion 2 includes a tray 201, and the tray 201 is detachably mounted above the base 1. When installing this pay-off, can place base 1 earlier with on the rail, again with tray 201 installation with base 1 on, avoided whole transport because weight is too big to cause the device installation difficulty to because tray 201 is the easy consume of part that bears cable weight, consequently detachable tray 201 makes things convenient for its change.
To facilitate rotatably mounting pay-off reel 3, support portion 2 may include a support shaft 202, support shaft 202 being mounted on tray 201, and pay-off reel 3 being rotatably mounted on support shaft 202 such that pay-off reel 3 can rotate relative to tray 201. Support shaft 202 may be fixedly mounted on tray 201 by welding or riveting, and support shaft 202 may be connected to the center of pay-off reel 3 by a bearing, so that pay-off reel 3 can rotate freely around support shaft 202.
In addition, a plurality of supporting wheels 303 may be installed at the bottom of the pay-off reel 3, the supporting wheels 303 are distributed on a circumference with a point on the center line of the supporting shaft 202 as a center, and the supporting wheels 303 can roll on the upper surface of the tray 201. Supporting wheel 303's height is the same with the distance of drawing drum 3 bottom to tray 201 upper surface, and a plurality of supporting wheels 303 are installed in drawing drum 3 bottom to make drawing drum 3 can remain stable when bearing cable weight and do not rock, and gyro wheel 303 can use back shaft 202 as centre of a circle free rolling friction reduction when the cable drives drawing drum 3 and rotates.
Optionally, the pay-off reel 3 includes a frame 301 and a plurality of support rods 302, the plurality of support rods 302 are fixed to the support shaft 202 in a crossing manner along the horizontal direction and are rotatably mounted, and the frame 301 is fixedly supported on the plurality of support rods 302. The supporting rods 302 have the same length, are fixedly intersected and rotatably mounted on the supporting shaft 202, and the included angle between every two adjacent supporting rods 302 is 360/the number of the supporting rods 302, so that the supporting rods 302 can be uniformly stressed, and the frame 301 is fixed on the same horizontal plane with the supporting rods 302 through the supporting rods 302 to reinforce the strength of the supporting rods 302.
To facilitate the rotation of the supporting wheel 303 around the center of circle, the supporting wheel 303 is a universal wheel. When the pay-off reel 3 rotates, the supporting wheel 303 rotates along a circle with the supporting shaft 202 as a circle center, the rolling direction of the supporting wheel 303 needs to be perpendicular to the circle center, if the supporting wheel 303 has deviation, abrasion is easily caused, the universal wheel avoids the problem that the angle is inconsistent with the rolling direction of the supporting wheel 303 when the universal wheel is installed, and the abrasion probability of the supporting wheel 303 is reduced.
In addition, to facilitate the fabrication of the frame 301, the frame 301 may have a square shape, and the axis of the support shaft 202 passes through the center of the square shape. The square frame 301 is simple to manufacture, stable in structure and large in bearing area.
Additionally, the support bar 302 may be a telescoping bar that defines a bearing surface of the payout reel. That is, the bearing surface is defined by the current length of the telescoping rod, thus the extent of the bearing surface can be varied. When the diameter of the cable shaft is too large to exceed the bearing surfaces defined by the frame 301 and the support rods 302, each support rod 302 can be stretched to increase the bearing surface of the pay-off reel 3, so that the pay-off device can meet cables of different sizes.
The base 1 is a rectangle, the number of the rollers 101 is four, and the four rollers 101 are symmetrically arranged on the long side of the base 1 in pairs, so that the rollers 101 can roll along the long direction of the base 1. The base 1 width matches the rail width and each roller 11 has a stop near the base 1 to enable the line payoff to move along the rail and prevent derailment.
And the pay-off reel 3 is detachably arranged on the supporting part 2. Make things convenient for pay-off's installation to can satisfy the replacement of different drawing drums 3.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. In the technical idea scope of the present invention, it is possible to provide the technical solution of the present invention with a plurality of simple modifications, including combining each specific technical feature in any suitable manner, and in order to avoid unnecessary repetition, the present invention does not provide additional description for various possible combinations. These simple variations and combinations should also be considered as disclosed in the present invention, all falling within the scope of protection of the present invention.
