Description

Secondary cable fast release rack

technical field

The invention relates to a cable pay-off frame, more specifically a cable pay-off frame 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.

Contents of the invention

In order to avoid the disadvantages of the above-mentioned prior art, the present invention provides a quick pay-off frame for secondary cables, so that during the laying process of secondary cables, the cables can be effectively protected from damage and the The pay-off process is quick and easy, reducing staffing and improving work efficiency.

The present invention adopts following technical scheme for solving technical problems:

The structural features of the secondary cable quick pay-off frame of the present invention are as follows: an upright "U" pulley bracket with an upward opening is provided, and two horizontally arranged upper and lower pulley brackets are used on the "U" type pulley bracket. An upper pulley and a lower pulley are respectively installed on the two axles, and the upper pulley and the lower pulley are respectively rotatable on their respective axles. The wires are routed in the groove; a horizontal "U"-shaped card with an opening facing one side is provided, and bolts are installed on the bottom plate of the horizontal "U"-shaped card, and the horizontal "U"-shaped card is used for fixing On the cable bracket, 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 "U" The "type pulley bracket is supported on the bearing and can rotate on the bearing.

The structural feature of the secondary cable quick pay-off rack of the present invention 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 be connected with hinge between described upper side board and lower side board, make described upper side board can turn outward on described hinge, the axle of described upper pulley is supported on described upper side board, so The shaft wheel of the lower pulley is supported on the lower side plate.

Compared with the prior art, the beneficial effects of the present invention are reflected in:

1. The present invention utilizes double pulleys to provide good protection for the cables in the secondary cable pay-off operation, avoiding damage to the cables during the pay-out process;

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

3. In the present invention, 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 use of the present invention can greatly reduce manpower and improve work efficiency.

Description of drawings

Fig. 1 is a structural representation of the present invention;

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 6 and can rotate on the bearing 6 In order to make the double pulley groove formed by the upper pulley 2 and the lower pulley 3 can rotate freely along with the trend of the cable, 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.
