Description

A magnetic manhole cover pick-and-place vehicle

technical field

The invention relates to the technical field of underground pipeline maintenance.

Background technique

With the development of modern industry and the expansion of urban construction scale, various manhole covers are used for buildings and roads. According to the function, there are various types of cables, communications, water supply, sewage, heating and so on. Especially with the increase of urban power supply and ground cable lines, more and more newly installed cable equipment and cable maintenance stations must be equipped with manhole covers. In the maintenance operation, the well cover must be moved out of the well head when it is opened, so that maintenance personnel can enter the well head for maintenance. In the prior art, opening the manhole cover is to manually pry off the heavy iron manhole cover. The disadvantages are: one, use a crowbar or a sharp-edged tool that can be used on site to pry and carry the manhole cover. The opening gap of the manhole cover is small and easy to pinch The fingers of the staff are prone to work-related accidents. 2. Due to the heavy manhole cover, it may cause damage to the manhole cover. Three manual operations are time-consuming and labor-intensive, which affects the efficiency of maintenance work. the

Contents of the invention

The technical problem to be solved by the present invention is to provide a magnet-type manhole cover picking and placing vehicle, which has the characteristics of simple structure, convenient and quick operation, safety and labor saving, and can open both ordinary manhole covers and heavy manhole covers.

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a magnet-type manhole cover pick-and-place vehicle, which is characterized in that it includes a pressure rod, the front end of the pressure rod is connected with the magnet, and the middle part of the pressure rod is connected to the two sides through the bracket. A wheel is connected, and the rear end of the pressure rod is provided with a handle.

A further improvement to the present invention is: the bracket is a U-shaped support plate with the opening facing downwards, the middle part of the pressure rod is connected to the axle through the U-shaped support plate, and the wheel is installed on the axle. The handle is a ring handle. The structure that the front end of the pressure rod is connected with the magnet is as follows: the front end of the pressure rod is connected with the horizontal tube, the vertical tube is connected below the horizontal tube, the lower end of the vertical tube is connected with the upper part of the cap, the The cap is provided with a blind hole opening downward, and the magnet is connected with the blind hole of the cap through bolts.

The beneficial effect produced by adopting the above-mentioned technical scheme is that: using the magnet-type manhole cover pick-and-place car, the operator presses down the handle, uses the leverage to lift the manhole cover through the magnet, and turns the pressure rod to move the manhole cover out of the wellhead, so that the ordinary manhole cover can be opened. It can also open heavy manhole covers. It saves labor and effort in the maintenance operation, shortens the opening time of the original manhole cover from 3-5 minutes to 10-15 seconds, avoids personal injury accidents, and improves work efficiency. the
