The invention provides a well cover plate lifting and descending movement device based on a rhombus-shaped lifting and descending mechanism. The well cover plate lifting and descending movement device comprises a concrete pit channel which is poured on a concrete pit; a cover plate is arranged on the concrete pit channel; the movement device further comprises the rhombus-shaped lifting and descending mechanism and a screw rod hand wheel mechanism, which are used for lifting and descending a cover plate, and a pulley wheel mechanism and a slide block mechanism, which are used for sliding the cover plate from left to right; the rhombus-shaped lifting and descending mechanism is fixedly mounted at the left sections of two inner walls of the concrete pit channel along the length direction; the screw rod hand wheel mechanism is arranged at the right end of the concrete pit channel; the pulley wheel mechanism comprises rails and a pulley wheel assembly; and the rails are mounted at the left sections of two inner walls of the concrete pit channel along the length direction. The invention provides the well cover plate lifting and descending movement device based on the rhombus-shaped lifting and descending mechanism, which is convenient to overhaul, relatively low in cost and relatively high in working efficiency.
Description
Technical field [0001] The invention relates to a lifting and lowering moving device for a well cover plate based on a diamond-shaped lifting mechanism. Background technique [0002] In today’s society, as a means of transmission, the pipeline transmission system is playing an increasingly important role. It transports various gas, liquid fuels and production and domestic water for production and life. There are many joints and valves installed in the pipeline transmission system. When used for a period of time, the joints and valves often have problems of one kind or another. Every time they are overhauled and replaced, the soil on the surface (sometimes the concrete pavement) needs to be removed before the relevant work can be carried out, and they are under the traffic road surface. For pipeline maintenance, the road must be closed for construction. This method is not only inefficient, but also destroys the surface vegetation or concrete pavement every time, which does not con...
