Description

Technical Field

[0001] The present application relates to the technical field of cable pay-off racks, and in particular to a horizontal cable pay-off rack. Background Art

[0002] In recent years, with the gradual increase in overhead line reconstruction projects, manual laying can no longer meet the needs of construction sites. Therefore, it is necessary to use a pay-out frame to lay the cables. Through the coordinated work of brackets, pulleys, fasteners and other parts, the cables can be supported, guided and tensioned, thereby protecting the cables from dragging and damage and improving the accuracy and efficiency of laying.

[0003] A Chinese invention patent with authorization announcement number CN107285126A discloses a horizontal pay-off stand for electric power. The patent can detect the weight of the cable inside the reel by setting a weight detector, which is convenient for workers to construct. Moving wheels and a second hydraulic telescopic rod are set to facilitate workers to move the pay-off stand, making it more convenient for workers to work. However, the horizontal pay-off stand for electric power is large in size, poor in flexibility, and not easy to carry. At the same time, it adopts an automated design, which is difficult to improve according to the specific pay-off situation and use environment. It is not practical and has a high cost of use.

[0004] Therefore, the present application provides a horizontal cable pay-off rack to solve the above problems. Utility Model Content

At the same time, it adopts an automated design, which is difficult to improve according to the specific pay-off situation and use environment. There are problems such as low practicality and high cost of use.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a horizontal cable pay-off rack, comprising a static load-bearing steel plate, a dynamic load-bearing steel plate arranged on the top of the static load-bearing steel plate, a positioning bolt fixedly arranged at the center of the static load-bearing steel plate, a limit bearing fixedly arranged on the positioning bolt and rotatably connected to the center of the dynamic load-bearing steel plate, a positioning square gasket rotatably arranged on the top of the limit bearing and fixedly connected to the positioning bolt, and at least three bull's eye universal bearings distributed in a circular array and fixedly arranged on the static load-bearing steel plate and in contact with the bottom of the dynamic load-bearing steel plate. In this way, when the horizontal cable pay-off rack is in use, the static load-bearing steel plate and the dynamic load-bearing steel plate are first assembled through the positioning square gasket and the positioning bolts. At this time, the device is moved to the location where it is required to be used, and the winding frame is manually placed on the top of the dynamic load-bearing steel plate. Since the bottom of the winding frame is generally in a through-hole state, when it is placed, the through-hole at the bottom of the winding frame is clamped on the positioning bolt to achieve a certain limiting effect. At this time, by utilizing the limiting bearing and the bull's eye universal bearing, the winding frame is rotated when paying out the wire. The bull's eye universal bearing can roll in any direction, contact and interact with the dynamic load-bearing steel plate, thereby achieving the effect of driving the dynamic load-bearing steel plate to rotate, so that the dynamic load-bearing steel plate rotates along the surface of the limiting bearing, thereby driving the top winding frame to rotate, thereby achieving the effect of quick and convenient paying out the wire.

[0007] Preferably, in order to facilitate movement and achieve reasonable installation of the load-bearing pull ring, horizontal grooves are symmetrically opened on the surface of the static load-bearing steel plate, and the horizontal cable pay-off rack also includes a base fixedly arranged at the bottom of the static load-bearing steel plate and grooves opened at the four corners of the static load-bearing steel plate; the static load-bearing steel plate can be supported by utilizing the base, and the slots are opened to achieve the effect of easy installation.

[0008] Preferably, in order to achieve reasonable limiting of the load-bearing pull ring; the notch is a vertical groove, and four load-bearing pull rings are arranged at the positions of the notches on both symmetrical sides of the static load-bearing steel plate, and a fixing plate is fixedly installed at the bottom of the load-bearing pull ring; by utilizing the fixing plate, since the diameter of the fixing plate is larger than the width of the notch, the problem of the load-bearing pull ring detaching during the upward pulling process is avoided.

[0009] Preferably, in order to achieve reasonable pulling, a handle for easy pulling is provided on the load-bearing pull ring, and the lifting can be performed by utilizing the handle.

[0010] Preferably, in order to achieve convenient movement; the handle includes a buckle that is clamped on the load-bearing pull ring and a hand rope fixed between related adjacent buckles; when the device needs to be moved, the load-bearing pull ring can be first inserted into the groove along the bottom of the static load-bearing steel plate, and then the handle is used to pull, and the buckle is clamped and fixed on the load-bearing pull ring on the same side, thereby fixing the hand rope. When it needs to be moved, the worker can lift and carry the load-bearing pull ring by holding the ropes on both sides. After the move is completed, the buckle is removed from the hand rope to facilitate the removal of the load-bearing pull ring from the groove, thereby completing the movement of the entire device.

[0011] Beneficial effect: the horizontal cable pay-off rack is designed and developed by setting static load-bearing steel plates, dynamic load-bearing steel plates, positioning bolts, limit bearings, and combining the "bull's eye universal bearing" technology to be a power cable construction pay-off rack with replaceable bearings, compact and light, and easy to operate, thus achieving lightweight of the pay-off rack. At the same time, by setting a handle, the equipment is more portable. BRIEF DESCRIPTION OF THE DRAWINGS
