Description

Cable trench cover plate lifting and moving device

Technical Field

The utility model relates to a carry and move the device, especially relate to a cable trench cover carries and moves device.

Background

When the cable is laid in the cable trench, small animals such as mice and the like often enter the cable trench to bite and damage the cable, so that accidents such as power failure and the like are caused. The safe operation of the transformer substation is a necessary condition for ensuring stable industrial and agricultural production and stable life of urban and rural people, prevents small animals from invading a cable trench, and is one of important measures for ensuring the safe operation.

In order to prevent small animals from entering the cable trench, the power supply department sets a solid plate cast by cement, namely a cable trench cover plate, on the cable trench. The cable trench cover plate is thick, heavy, closed, good in mechanical strength, and covers the top of the cable trench, and is used for preventing small animals, rainwater and the like from entering the cable trench, so that the purpose of protecting the cable is achieved.

According to relevant regulations, the inspection of a transformer substation for preventing the blockage of the small animals is required to be included in the daily maintenance work of teams, and the inspection of the condition of a cable trench of a high-voltage field is one of the work; in addition, when there is reconstruction and extension work in the station and related work such as laying cables in the cable trench is needed, a plurality of cable trench cover plates covering the cable trench also need to be lifted, moved and replaced. Therefore, the workload is large when the trench cover plate is frequently lifted, moved and replaced. Lifting, replaying, or moving the cover plate requires at least two persons working in cooperation, and the two persons are opposite to each other. When the cable trench cover plate is lifted and moved or put back, firstly, two persons stand at two sides of the trench cover plate respectively, and try to search for reliable stress points by repeatedly and tentatively slightly extracting the cable trench cover plate edge back and forth with two hands; after finding out the reliable stress point, two persons apply force to extract or move the cable trench cover plate at the same time, and the cable trench cover plate is placed on the nearby ground or trench cover plate; similarly, when the cable is put back, after a reliable stress point is found, two persons apply force to lift the cable at the same time and put the cable back to the original cable trench.

The conventional cable trench cover has the length of 80-160cm, the width of about 50cm and the thickness of about 3cm, the weight of 40-80Kg, and the cable trench cover is large and heavy, and the following problems are often caused in the extraction and replacement processes: firstly, the lifting and moving of the cable trench cover plate are time-consuming and labor-consuming; secondly, fingers of the extraction personnel are easily crushed; and thirdly, the lifting personnel are very easy to slide down due to uneven palm exertion, thereby causing harm to the personnel.

Due to the lack of proper tools, at present, the working method of directly moving the cable trench cover plate by using the palm not only seriously affects the working efficiency, but also threatens the physical health of workers and even generates psychological barrier.
