Description

Composite insulator lifting fixture

technical field

The utility model relates to a composite insulator hoisting fixture.

Background technique

Composite insulators are mainly composed of two parts before flange installation: silicone rubber shed sheath, glass fiber winding pipe (rod), and there is no hanging rope hanging position, so hoisting and transportation are very inconvenient. At present, such composite insulators can only be hoisted with hanging ropes to bind the sheds. Since the silicone rubber sheds are relatively soft and easily scratched, the surface quality of the sheds is easily damaged during the hoisting process. At the same time, when the flange is poured, the axis of the composite insulator is required to be perpendicular to the ground. It is difficult to adjust the lifting angle by the method of tying the rope, and the operation is very inconvenient.

The Chinese patent specification with application number 201120355479.2 discloses a tool for hoisting insulators, which does not need binding during the process of hoisting and supporting insulators. The tooling includes a steel frame, sling, release rope and clamping parts. The steel frame adopts a scissors structure design. The steel frame is composed of two clamp arms, which are connected by a pin shaft. The rear end of the steel frame clamp arm There is a lifting point, the lifting rope is connected to the lifting point, the release rope is connected to the steel frame at the front end of the pin shaft, the steel frame head is provided with a clamping part, and the inner side of the clamping part is provided with a pad. The tooling uses the principle of leverage to clamp the outer surface of the glass fiber wound pipe under the action of the weight of the steel frame itself and the upward pulling force of the crane, and uses the weight of the product itself to obtain sufficient friction to lift the insulator. However, this tool has certain limitations: for example, it can only lift products that are already in a vertical state, and the products must be placed vertically when they fall to the ground, and cannot be placed horizontally; the friction force decreases rapidly with the landing of the product, and there are certain safety hazards .

Utility model content

The purpose of the utility model is to provide a composite insulator hoisting fixture with reliable installation, so as to realize the horizontal placement of the insulator during the hoisting process.

In order to achieve the above object, the utility model adopts the following technical scheme: the composite insulator hoisting fixture includes more than two arc-shaped arms used to connect to the hoop that hugs the outer peripheral surface of the end of the winding pipe, and each arc-shaped arm has A concave surface that fits with the outer peripheral surface of the end of the winding pipe. At least two or more arc arms are fixed with suspension rings or hooks. Each adjacent arc arm has a corresponding end that cooperates with each other. At least one pair of corresponding ends A corresponding detachable fixed connection structure is provided between them, and a hinged connection structure or a corresponding detachable fixed connection structure is provided between the other pairs of corresponding ends.

The detachable fixed connection structure includes outward flanges fixed on a pair of corresponding ends extending radially along the arc-shaped arms, and adjacent outward flanges are detachably fixedly connected by bolts or screws.

The hinge connection structure includes a connecting plate arranged on the upper and lower end faces of a pair of corresponding end parts, and the connecting plate and the corresponding corresponding end parts are provided with a rotating shaft penetrating in the up and down direction.

Patterns are provided on the concave surface of the arc-shaped arm or a rubber sheet is fixedly pasted.

The beneficial effect of the utility model is that the adjacent arc arms of the hoop can be opened and closed, and when each arc arm is closed, the end of the winding pipe can be clamped. Therefore, hoisting can be realized by hanging the lifting point on the arc arm with the hook of the crane. When the hoop is hoisted, the pressure generated by the arc arm on the winding pipe can be converted into static friction force, which can be changed with the gradually increased with increasing pressure. By adopting the composite insulator hoisting fixture of the utility model, various actions such as transportation, horizontal placement, and vertical hoisting of the insulator during the hoisting process can be realized. The utility model has safe and reliable performance. At the same time, since the clamp is assembled at the end of the insulator winding tube, the clamp is far away from the silicone rubber shed sheath, which can effectively protect the silicone rubber shed sheath and avoid the quality defects caused by the hanging rope directly binding the shed shed (such as umbrella Skirt squeeze, scratches, surface pollution, etc.), not only improves production efficiency, but also reduces the workload of subsequent processes on the surface repair and cleaning of umbrella skirts, and reduces production costs.

Further, since the concave surface of the arc-shaped arm is provided with a pattern or fixedly attached with a rubber sheet, the pattern or the rubber sheet can increase the friction coefficient of the arc-shaped arm, thereby improving the safe use performance of the utility model.
