technical field

The utility model relates to a cable pay-off stand, more specifically a cable pay-off stand used in secondary cable laying operations.

Background technique

In the process of power overhaul and maintenance, the laying of secondary cables is often involved. The secondary cable laying operation is very demanding, and there are various problems in the actual operation: including many cable trenches or cable channel corners, narrow working position and inconvenient operation, difficulty in arranging a large number of cables, and difficulty in cable entrapment. Low, its external protection is weak, and it is easy to be damaged by external force during laying, which results in a heavy workload for secondary cable laying.

At present, in the actual construction, the N+2 mode is mostly used for the secondary cable laying, that is, one operator needs to be arranged at each corner of the cable trench, and one operator is arranged at each end of the cable trench, which makes the two The process of secondary cable laying requires a large number of operators. For the conventional substation arrangement, it often takes 5-6 people to complete a secondary cable laying, and it takes more than two days of working time.

Utility model content

The utility model is to avoid the disadvantages of the above-mentioned prior art, and provides a secondary cable quick pay-off frame, so that during the laying process of the secondary cable, the cable can be effectively protected from damage, and the Make the pay-off process quick and easy, reduce staffing and improve work efficiency.

The utility model adopts following technical scheme for solving technical problems:

The structural features of the utility model secondary cable fast pay-off rack are as follows: set up an upright "U" type pulley bracket with the opening facing upwards, and use one up and one down horizontally set up on the "U" type pulley bracket. Two axles, upper pulleys and lower pulleys are installed correspondingly on the two axles, and the upper pulleys and lower pulleys are respectively rotatable on their respective axles. Wires are routed in the wire groove; a horizontal "U"-shaped card with an opening facing one side is provided, and bolts are installed through the bottom plate of the horizontal "U"-shaped card, so that the horizontal "U"-shaped card can It is fixed on the cable bracket, and the horizontal "U"-shaped card is detachably fixed on the cable bracket by the bolt; a bearing is arranged on the top plate of the horizontal "U"-shaped card, and the " The U" type pulley support is supported on the bearing and can rotate on the bearing.

The structural feature of the secondary cable quick pay-off frame of the utility model is also that: any side plate in the two side plates constituting the support in the "U" type pulley bracket is an upper side plate and a lower side plate arranged separately. , and are connected by a hinge between the upper side plate and the lower side plate, so that the upper side plate can turn outward on the hinge, and the axle of the upper pulley is supported on the upper side plate, The shaft wheel of the lower pulley is supported on the lower side plate.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

1. The utility model uses double pulleys to protect the cables well during the secondary cable pay-off operation, avoiding damage to the cables during the pay-out process;

2. The arrangement of double pulleys and bearings in the utility model can meet the requirements of the upward, downward and various angles of the cables.

3. In the utility model, double pulleys are used to limit the position of the cables, so that the cables can be tidied up during the laying process, and the bundling process is also faster and more convenient.

4. The utility model can greatly reduce manpower and improve work efficiency.

detailed description

Referring to Fig. 1, the structural form of the secondary cable quick pay-off rack in the present embodiment is:

An upright "U" type pulley support 1 with an opening facing upwards is set. On the "U" type pulley support 1, two wheel shafts that are horizontally arranged one above the other are utilized, and upper and lower shafts are installed on the two wheel shafts in one-to-one correspondence. The pulley 2 and the lower pulley 3, the upper pulley 2 and the lower pulley 3 can rotate on their respective axles respectively, and the cable is routed in the closed wheel groove formed by the upper pulley 2 and the lower pulley 3, with the closed wheel groove as the The wire slot 4 ensures that the cables will not slip off from the wire slot 4. The "U" pulley bracket with the opening facing upwards is adopted, which can withstand lateral force, is convenient to open and close, and has good fastening performance; the double pulley structure enables the cables to be protected and guided in both upward and downward directions, reducing little friction.

Set a horizontal "U"-shaped card with an opening facing one side, and a bolt 6 is installed on the bottom plate 5a of the horizontal "U"-shaped card; It is clamped on the cable bracket, and the horizontal "U"-shaped card is detachably fixed on the cable bracket by the bolt 6. This structural form of fixing on the cable bracket allows the cable to be directly connected after the wiring is completed. Bundled on the cable bracket, the wiring and bundling are completed synchronously; a bearing 7 is set on the top plate 5b of the horizontal "U"-shaped card, and the "U"-shaped pulley bracket 1 is supported on the bearing 7 and can rotate on the bearing 7. So that the double pulley slot formed by the upper pulley 2 and the lower pulley 3 can freely rotate along with the direction of the cable, and the bearing structure not only ensures that it can rotate flexibly in the horizontal direction, but also has good stability.

In order to facilitate the assembly of the pulley on the "U" type pulley bracket, any one side plate in the two side plates constituting the bracket in the "U" type pulley bracket 1 is an upper side plate 1a and a lower side plate 1b which are separately provided. , and between the upper side plate 1a and the lower side plate 1b are connected with a hinge 1c, so that the upper side plate 1a can turn outward on the hinge 1c, the axle of the upper pulley 2 is supported on the upper side plate 1a, and the lower pulley 3 The shaft wheel is supported on the lower side plate 1b.

When installing the upper pulley 2, first turn the upper side plate 1a to the outside, so that the "U" opening of the "U" type pulley bracket 1 is opened larger, and then the upper pulley 2 is installed. This process is very convenient to operate and fast.

In specific implementation, the upper pulley 2 and the lower pulley 3 are made of nylon material and processed from nylon rods, which are light in weight, high in strength, wear-resistant and small in frictional resistance, and are not easy to damage cables.
