Description

Temporary fence retractable device

technical field

The utility model relates to the technical field of engineering, in particular to a retractable device for a temporary fence.

Background technique

The substation is an important part of the power grid and an important infrastructure in the region. The step-up and step-down processing of electric energy through the substation is an important means to realize the long-distance transmission and distribution of electric energy. At present, all countries use step-up substations to upgrade electric energy to a high voltage level, then use high-voltage transmission lines to transmit it to the load side, and then use step-down substations to convert the high voltage into the low voltage required by users. Due to the need for repair and maintenance of power equipment, switching operations are often carried out in substations, among which hanging signs and installing temporary barriers are important technical measures to ensure safety.

Most of the existing temporary fences are made of metal, so large vehicles are needed to transport them, and the installation of such metal temporary fences is time-consuming and labor-intensive. With the continuous development of the power grid, the number of substations in various places continues to rise, and the amount of operational tasks brought about by this has increased sharply. The previous method of installing and dismantling temporary fences caused the problems of long power outages and low reliability of the power grid.

In order to be able to set up temporary fences conveniently, mesh fences are now used, which can be easily rolled up when not in use, and solve the problem that the existing metal fences are not easy to carry. This kind of temporary fence can not only play the role of warning and isolation, but also is convenient to fold and occupy a small space. However, the existing mesh fences are all made of ropes, which are easy to be entangled when rolled up, and it takes a lot of time to sort them out. Therefore, when in use, usually the staff uses a wooden stick as a shaft, and rolls the mesh fence on the shaft; this very primitive way causes low work efficiency.

Utility model content

Aiming at the problems existing in the prior art, the technical problem to be solved by the utility model is to provide a temporary fence retractable device that can use the mesh fence more conveniently and efficiently.

In order to achieve the above object, a temporary fence retractable device includes a main roller, wherein the main roller is provided with a rotating shaft so that the main roller can rotate along its axis; the outer peripheral surface of the main roller is provided with An arc-shaped hanging rod group extending on the outer peripheral surface of the main roller, the connecting rod set includes a plurality of connecting rods, the bottom of each connecting rod is fixed on the main roller, and is perpendicular to the The surface of the main roller extends toward a direction away from the main roller; wherein the connecting rods of the connecting rod group are arc-shaped distributed on the outer peripheral surface of the main roller along the vertical direction.

Wherein, a handle is provided on the top of the main roller to drive the main roller to rotate along a vertical axis.

Wherein, the top of the main roller is provided with a polygonal socket, the handle includes a horizontal connecting rod, one end of the horizontal connecting rod is fixedly connected to a socket extending toward the bottom of the horizontal connecting rod, and the end of the socket is provided with a The polygonal socket matches the polygonal plug; the other end of the horizontal connecting rod is connected to the grip part extending toward the top of the horizontal connecting rod through a rotating shaft.

Wherein, the top and the bottom of the main roller are provided with limiting guard plates.

Wherein, a bracket is also included, and two supporting parts are arranged on the bracket to be respectively fixed at both ends of the shaft of the main roller so that the shaft of the main roller is arranged in a horizontal direction.

The beneficial effects of the above-mentioned technical solution of the utility model are as follows: the temporary fence retracting device of the embodiment of the utility model can be rotated very conveniently to retract and retract the net-shaped temporary fence, and can be distributed on the outer periphery of the main roller through arcs. Post set to hang mesh temporary guardrail. This arc-shaped distribution can ensure that the main roller has only one hooking rod in the vertical section and horizontal section at the same time, so that it can not only ensure that the mesh of the mesh temporary guardrail is inserted into the hooking rod, but also prevent excessive hooking Rods are too cumbersome to hook up.

detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The embodiment of the utility model proposes a temporary fence retractable device, the structure of which is shown in Figure 1, including a main roller, wherein the main roller is provided with a rotating shaft so that the main roller can rotate along its axis; The outer peripheral surface of the main roller is provided with a set of hook rods extending along the axial direction in an arc shape on the outer peripheral surface of the main roller, the set of hitch rods includes a plurality of hitch rods, the bottom of each hitch rod is fixed On the main roller, perpendicular to the surface of the main roller and extending in a direction away from the main roller; wherein the connecting rods of the connecting rod group are arc-shaped distributed on the main roller along the vertical direction on the outer peripheral surface. Wherein, a handle is provided on the top of the main roller to drive the main roller to rotate along a vertical axis. Wherein, the top of the main roller is provided with a polygonal socket, the handle includes a horizontal connecting rod, one end of the horizontal connecting rod is fixedly connected to a socket extending toward the bottom of the horizontal connecting rod, and the end of the socket is provided with a The polygonal socket matches the polygonal plug; the other end of the horizontal connecting rod is connected to the grip part extending toward the top of the horizontal connecting rod through a rotating shaft. Wherein, the top and the bottom of the main roller are provided with limiting guard plates. Wherein, a bracket is also included, and two supporting parts are arranged on the bracket to be respectively fixed at both ends of the shaft of the main roller so that the shaft of the main roller is arranged in a horizontal direction.

Wherein, the heights of the connecting rods of the connecting rod group are all the same. Further, in order to prevent the problem that the height of the hooking rod is not enough after winding up too many netted temporary fences, the temporary fence retracting device can further include a hooking rod extension sleeve, and the hooking rod extension sleeve is The cylindrical shape is provided with an axial blind hole, and the inner diameter of the axial blind hole is larger than the outer diameter of the connecting rod so as to be sleeved on the connecting rod and play the role of extending the connecting rod.

The foregoing is a preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can be made without departing from the principle of the present utility model. Retouching should also be regarded as the scope of protection of the present utility model.
