Description

Technical Field

[0001] The utility model relates to the technical field of cable laying-out, in particular to a cable laying-out device. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulating cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors. When used in urban buildings, wires and cables require the cooperation of a wire-laying device to complete the work.

[0003] The conventional wire and cable pay-off device has the following shortcomings: the pay-off speed and pay-off length of the conventional wire and cable pay-off device are uncontrollable, and the conventional wire and cable pay-off device also has the problem of being bulky and difficult to carry and move.

[0004] For example, a wire and cable unwinding device disclosed in Chinese patent CN208249507U is provided with a base and universal wheels. The base is welded under the left support frame and the right support frame, which can effectively increase the stability of the device. At the same time, the universal wheels facilitate the daily movement and transportation of the equipment in all directions, thereby saving the operator's physical strength. By providing a first fixing hole, a second fixing hole, and a fixing rod, the fixing rod passes through the second fixing hole provided on the left support frame and is connected with the first fixing hole, that is, the fixing rod can be freely removed and installed, thereby limiting the rotation of the left guard plate and the rotating rod, thereby achieving the purpose of limiting the release length of the wires and cables.

[0005] However, it is not convenient to disassemble the rotating rod from the wire-releasing device, so that after all the cables at the outer end of the rotating rod are released, it is not convenient to replace a new rotating rod with the cables wound thereon to carry out the wire-releasing work.

[0006] For this reason we urgently need to provide a kind of cable pay-out device that is easy to disassemble and assemble. Utility Model Content

[0007] The purpose of the utility model is to provide a cable pay-off device to solve the problem that the pay-off device proposed in the above background technology is not convenient to remove the rotating rod from the pay-off device, so that after all the cables on the outer end of the rotating rod are paid out, it is not convenient to replace a new rotating rod with the cable wrapped around it to carry out the pay-off work.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable pay-off device, comprising a base plate and a universal wheel, the universal wheel being fixedly connected to the front and rear ends of the lower side of the base plate, a support column being fixedly connected to the upper middle position of the base plate, a bearing being fixedly connected to the middle position inside the upper end of the support column, a round rod being fixedly connected to the inner side of the bearing, a pay-off mechanism being connected to the upper end of the support column, the pay-off mechanism comprising a pay-off unit and a fixing unit, the pay-off unit being arranged at the upper end of the support column, and the fixing unit being arranged at the upper end of the support column.

[0009] The pay-off unit includes a pay-off shaft, a guard plate, a ring, a connecting frame, a spring, a circular ring and an insert rod. The pay-off shaft is fixedly connected to the outer end of the circular rod, the guard plate is fixedly connected to the left and right ends of the pay-off shaft, the ring is fixedly connected to the middle position of the side of the guard plate away from the pay-off shaft, the connecting frame is fixedly connected to the outer upper end of the ring, the spring is fixedly connected to the middle position of the inner top end of the connecting frame, the circular ring is fixedly connected to the lower end of the spring, the insert rod is fixedly connected to the inner side of the circular ring, and a turning handle is fixedly connected to the left side of the circular rod on the left side of the pay-off shaft.

[0010] A further improvement is that a limiting hole is provided at the middle position of the upper end of the connecting frame and the middle position of the upper end of the ring, and the outer side of the insertion rod is slidably connected to the inner side of the limiting hole. Therefore, when the spring drives the ring to move, the insertion rod can be driven to slide along the inner side of the limiting hole, thereby limiting the movement of the insertion rod.

[0011] A further improvement is that a plug hole is provided in the middle position of the inner upper part of the end of the round rod away from the bearing, the outer side of the lower end of the plug rod is plugged into the inner side of the plug hole, and the outer side of the end of the round rod away from the bearing is slidably connected with the inner side of the collar. Therefore, after the end of the round rod away from the bearing is slid to the inner side of the collar, the plug rod rebounds and pushes down the collar, driving the plug rod to move downward, until the lower end of the plug rod moves down into the plug hole, so that the round rod can be fixed to the inner side of the collar.

[0012] A further improvement is that the fixing unit includes a support plate, a threaded rod and a rotating handle, the support plate is fixedly connected to the middle position on the upper side of the support column on the left side of the pay-off shaft, the threaded rod is connected to the inside of the upper end of the support plate, and the rotating handle is fixedly connected to the left end of the threaded rod.

[0013] A further improvement is that a threaded hole is provided in the middle of the upper end of the support plate, and the outer side of the threaded rod is threadedly connected to the inner side of the threaded hole, so that when the rotating handle is turned to drive the threaded rod in the threaded hole to rotate, the threaded rod can move relative to the support plate.

[0014] A further improvement is that round holes are opened at equal distances on the inner edge of the guard plate on the left side of the pay-off shaft, and the outer side of the right end of the threaded rod is plugged into the inner side of the plug hole. Thus, the pay-off shaft is rotated by turning the handle to drive the round rod to rotate, and after the cable on the outer side is paid out, the threaded rod is driven to rotate and move rightward by turning the rotating handle until the right end of the threaded rod moves rightward to the plug hole at the corresponding position on the inner edge of the guard plate, so that the guard plate can be fixed, thereby fixing the pay-off shaft and the cable on the outer end and no longer paying out.

[0015] A further improvement is that the outer side of the pay-off shaft is provided with anti-slip grooves, so that the cable can be more firmly wound around the outer side of the pay-off shaft.

[0016] In summary, the present application discloses a cable pay-out device.

[0017] The technical solution is to pull up the plug rod so that its lower end moves up to the point where it is no longer located in the socket, and then the round rod can be pulled out of the ring, so that the pay-off shaft and the guard plate at its outer end after the cable is released are removed from between the support columns, and then the rings at the outer ends of the guard plates on the left and right sides of the pay-off shaft with the cable wrapped around them are slid to the outside of the round rod, and then the plug rod rebounds and pushes down the ring, driving the plug rod to move downward, until the lower end of the plug rod moves down to the socket, and then a new pay-off shaft is installed between the support columns, so that the pay-off shaft can be replaced after all the cables at the outer end of the pay-off shaft are released.

[0018] Furthermore, the pay-off shaft is rotated by turning the handle to drive the round rod to rotate, and after the cable on the outside is paid out, the threaded rod is driven to rotate and move right at the same time by turning the rotating handle until the right end of the threaded rod moves to the right to the socket at the corresponding position on the inner edge of the guard plate, so that the guard plate can be fixed, thereby fixing the pay-off shaft and the cable on the outer end and no longer paying out.
