Description

A portable take-up roller system

technical field

The utility model belongs to electric construction devices, in particular to a portable take-up roller system.

Background technique

In the power system, there are various measurements, and the cable, as the carrier of the current, needs a large number of applications in the measurement field. Taking the measurement of the grounding system of power generation and substations in the power system as an example, the diagonal length of the grounding grid of the power station varies from tens of meters to several kilometers. In the above position, the straight-line distance between the voltage pole and the edge of the ground grid of the power station also needs to be several times the length of the diagonal line. At the same time, considering the twists and turns of the road between the two points, the voltage lead wire and the current lead wire need to be hundreds of meters to tens of kilometers long. This requires a larger workload for cable retraction.

At present, many portable take-up rollers in the market are integrated with the wire reel and the take-up roller, which is laborious to use. However, the electrified take-up device in the factory neither solves the problem of paying off the wire, nor is it suitable for collecting along the road. At the same time, although the wire take-up device used in the factory is driven by a motor and has high efficiency, the device is bulky and requires a power supply, so it is not suitable for on-site use.

In addition, the integrated take-up roller takes up a lot of space, and the cable length of the reel is generally not long, which is only suitable for the requirements of tens of meters of pay-off. On-site measurement, especially for the measurement of the grounding system of large-scale hydropower stations, often requires several kilometers, or even Tens of kilometers of cables, which require reels that are wound in long lengths and easy to transport. To lay out cables of several kilometers or even tens of kilometers usually requires dozens of reels, which requires that the reels must be convenient for storage and transportation.

Utility model content

The technical problem to be solved by the utility model:

One is that the portable take-up roller integrated with the reel and take-up roller is laborious to use, and the electrified take-up device in the factory cannot pay off the wire, and it is not suitable for the working conditions of taking up the wire along the road.

The second is on-site measurement, especially for the measurement of the grounding system of large-scale hydropower stations. Cables of several kilometers or even tens of kilometers are often required. Therefore, it is necessary to wind a coil with a long length, easy to replace, and easy to store and transport.

The technical scheme adopted in the utility model is: a portable take-up roller system, including a take-up roller skeleton and a rotating mechanism, the rotating mechanism including a wire reel, a buckle reel, a roller bar and a gear system, and the two sides of the wire reel Engage with the buckle disc respectively, the roller rod passes through the center of the wire reel and the buckle disc and engages with the buckle disc; the two sides of the roller rod are connected to the frame of the take-up roller through bearings connected; the gear system is set on the take-up roller skeleton.

Further, the gear system includes a driving gear arranged on the skeleton of the take-up roller and a driven gear arranged at one side end of the roller bar, the driving gear and the driven gear mesh with each other.

Further, a rocker is installed on the drive gear.

Further, two cable holes are opened on one side of the wire reel, four buckle grooves are evenly distributed on both sides, and a roller bar hole A is opened in the center.

Further, the buckle plate is designed with 4 buckle protrusions evenly distributed, and a roller bar hole B is opened in the center, and a gap is opened in the roll bar hole B, and the roll bar hole B of the buckle plate The diameter is equal to the diameter of the roller rod, and is smaller than the diameter of the hole A of the roller rod of the coil.

Further, the two sides of the roller bar are respectively provided with protrusions corresponding to the gaps in the hole B of the roller bar.

Further, it also includes a detachable fastener on the frame of the take-up roller, and the fastener fixes the bearing on the frame of the take-up roller.

Further, the fastener adopts a U-shaped slot, and is connected with the frame of the take-up roller through screws.

Furthermore, the frame of the take-up roller adopts a steel structure, and there are openings on both sides above.

The working principle of the utility model: when the wire is retracted and unwound, two buckle discs buckle the two sides of the wire drum, and the roller bar bites the buckle disc. The driven gear on the take-up roller meshes with the driving gear on the frame of the take-up roller. By rotating the rocker on the driving gear, the driven gear is driven. The driven gear drives the roller to rotate, and the roller drives the buckle disc to rotate. The bite of the wire reel drives the rotation of the wire reel to complete the work of receiving and releasing the wire.

When the wire reel is full of cables or after the cables are placed, unscrew the screws of the fasteners to remove the roller bar, buckle reel and wire reel together. Remove the buckle reel and wire reel, replace the wire reel, reassemble, and start another round of receiving and releasing work.
