Hydraulic lifting system and heating method thereof

Abstract

The invention provides a hydraulic lifting system and a heating method thereof. The hydraulic lifting system adopts an upper anchorage oil cylinder and a lower anchorage oil cylinder for clamping and loosening steel strands, so that the hydraulic lifting system is safe and highly-efficient in operation; and in a freezing environment, the hydraulic lifting system can realize heating for a hydraulic oil pump and a hydraulic oil way through a telescopic cylinder of a main oil cylinder by using the heating method of the hydraulic lifting system under the conditions of not increasing other parts or lifting a lifting structure so as to enable the hydraulic oil pump and the hydraulic oil way of the hydraulic lifting system to reach the temperature required for normal operation, and ensure that the hydraulic lifting system also can safely operate in the freezing environment.

Description

Technical field [0001] The invention relates to the field of lifting and installation, in particular to a hydraulic lifting system and a heating method thereof. Background technique [0002] When large objects need to be lifted and moved to high places, lifting systems are generally used to lift objects. With the continuous advancement of modern technology, hydraulic technology has been added to the lifting system and has been widely used when lifting large objects. use. The hydraulic lifting system generally uses a hydraulic pump station to drive the jack up and down to reciprocate and retract to drive the steel strand to move up and down, so that the steel strand drives the objects on the lifting structure up and down to achieve the purpose of lifting the objects. [0003] The oil temperature in the hydraulic oil pump has a great influence on the performance of the hydraulic system. For the hydraulic lifting system in the outdoor environment in cold areas, the oil temperature in...

Problems solved by technology

Usually the heating method is to heat the oil tank in the oil pump to increase the oil temperature of the hydraulic oil in the oil tank to achieve the effect of heating up, but only heating the oil tank does not have a heating effect on the hydraulic pipeline, and it cannot guarantee that the overall hydraulic lifting system is in good condition. Operating at the temperature required for normal operation will reduce the efficiency of the lifting, and even the hydraulic lifting system cannot be started or fails to operate due to the oil temperature or the hydraulic pipeline being too cold.
