Abstract

The utility model relates to a wire hanging hook used for a power equipment test. The wire hanging hook comprises a hook outer ring. A hook internal-diameter herringbone clamp is arranged on the inner side of the hook outer ring. The hook internal-diameter herringbone clamp is provided with hook internal-diameter herringbone clamp springs in a matched mode. The bottom part of the hook outer ring 1 is provided with a hook bottom support connecting groove. The lower end of the hook bottom support connecting groove is fixedly connected with a hook bottom support. The length of the overlapped part of the two sides of hook internal-diameter herringbone clamp is more than three centimeters, so that the requirement that a testing hook firmly clamps a hung device is met; and the inner side of the hook bottom support is in an inwards concave conical slope shape, thereby facilitating the connection of a testing rod. The wire hanging hook provided by the utility model solves the problems that the hanging and connection of the testing hook is not firm, and the testing hook is not easy to take off, so that work efficiency is improved, and test safety is increased.

Description

A kind of test wire-hanging hook for power equipment test usefulness

Technical field

The utility model relates to a kind of test wire-hanging hook of power equipment test usefulness, is mainly used in articulating of electric system high-potting and relevant ground wire.

Background technology

In electric system high-potting and the operational process, need to articulate test wire and ground wire to primary equipment, the test hanging wire needs standard trolley and wire-hanging hook, mainly is divided into: the separable two kinds of forms of the equipment of wire-hanging hook and standard trolley one and standard trolley and wire-hanging hook.At present, adopt the most widely or standard trolley and the separable hanging wire form of wire-hanging hook, the separable pattern of standard trolley and wire-hanging hook just relates to articulating of wire-hanging hook and takes process, existing test wire-hanging hook is in the process of taking, because the too little capturing position that is not easy in aperture, it is very difficult to take the test wire-hanging hook.

The utility model content

Of the present utility model PurposeArticulate characteristics with regard to being for the test wire in present electric system high-potting and the operational process, a kind of power equipment test wire-hanging hook of plucking of being convenient to hang is provided, the test hook connects insecure in the solution process of the test, the test hook is taken an inconvenient difficult problem, increase work efficiency, increase experimental safe.

Of the present utility model Technical schemeFor:

A kind of power equipment test wire-hanging hook, comprise the hook outer shroud, be provided with hook internal diameter herringbone folder in hook outer shroud inboard, hook internal diameter herringbone folder is equipped with hook internal diameter herringbone folder spring, be provided with hook collet link slot at hook outer shroud root, be fixedly connected with the hook collet under the hook collet link slot; More than the both sides lap of described hook internal diameter herringbone folder is made as centimetre, satisfies the test hook and firmly clamp and hung standby requirement; Described hook collet inboard is made as the inner concave conical inclined-plane of the connection of being convenient to check bar.

Hook outer shroud described in the utility model and hook collet link slot adopt Split connection structure.

The utility model Beneficial effect be:

Characteristics of the present utility model are divided into three aspects: the one, and the improvement that hook internal diameter herringbone presss from both sides strengthens herringbone folder lap, makes the hanging wire folder and is hung for being connected more firm; The 2nd, the hook collet adopts three-dimensional conical surface design, increases the contact area of standard trolley and wire-hanging hook, and the collet internal diameter adopts small-bore design, avoids using the generation of the rock situation of standard trolley in taking the process of wire-hanging hook under the heavy caliber; The 3rd, hook outer shroud and hook collet link slot 4 adopt the split connected mode, make the use of wire-hanging hook more flexible.

The utility model is simple in structure, small and exquisite, has strengthened the radian of hook internal diameter herringbone folder, and it is more firm that test wire is connected.Adopt the collet of three-dimensional conical surface design, conveniently the test hook takes the security of strengthen test hanging wire.Adopt the wire-hanging hook mode that split is connected with collet, avoid the waste of original test wire-hanging hook, make up more flexible.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Wire-hanging hook is used in a kind of power equipment test of the utility model as shown in drawings, comprises hook outer shroud 1, and hook outer shroud 1 is according to the hanging wire object maximum selection rule of test; Be provided with hook internal diameter herringbone folder 2 in hook outer shroud 1 inboard, hook internal diameter herringbone folder 2 is equipped with hook internal diameter herringbone folder spring 3, is provided with hook collet link slot 4 at hook outer shroud 1 root, and hook collet link slot is fixedly connected with hook collet 54 times; The both sides lap of described hook internal diameter herringbone folder 2 is made as more than 3 centimetres, and satisfied test hook is firmly clamped and hung standby requirement.Described hook collet 5 inboards are made as the inner concave conical inclined-plane of the connection of being convenient to check bar, are convenient to the connection of check bar.Described hook outer shroud 1 adopts Split connection structure with hook collet link slot 4.

Claims

1. a power equipment is tested and is used wire-hanging hook, it is characterized in that: this wire-hanging hook comprises the hook outer shroud, be provided with hook internal diameter herringbone folder in hook outer shroud inboard, hook internal diameter herringbone folder is equipped with hook internal diameter herringbone folder spring, be provided with hook collet link slot at hook outer shroud root, be fixedly connected with the hook collet under the hook collet link slot; More than the both sides lap of described hook internal diameter herringbone folder is made as centimetre, satisfies the test hook and firmly clamp and hung standby requirement; Described hook collet inboard is made as the inner concave conical inclined-plane of the connection of being convenient to check bar.

2. wire-hanging hook is used in a kind of power equipment test according to claim 1, and it is characterized in that: described hook outer shroud and hook collet link slot adopt Split connection structure.
