Abstract

The invention discloses a hose follow-up device and a hydraulic grab machine, and relates to the technical field of engineering machines. The hose follow-up device and the hydraulic grab machine solve the technical problem that in the prior art, the service life of a hose is short. The hose follow-up device comprises an energy storage element, a hose and a hydraulic energy conversion drive mechanism, and the hydraulic energy conversion drive mechanism is connected between the energy storage element and the hose. Mechanical energy generated when the hose stretches outwards can be converted into hydraulic energy through the hydraulic energy conversion drive mechanism and then the hydraulic energy is stored in the energy storage element, the hydraulic energy conversion drive mechanism can also receive the hydraulic energy released by the energy storage element and drive the hose to be withdrawn through the hydraulic energy. The hydraulic grab machine comprises a hydraulic grab body, a grab body opening and closing oil cylinder, a rotary table and the hose follow-up device. The hose follow-up device and the hydraulic grab machine are used for prolonging the service life of the hose and reducing power losses of a hydraulic system.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a hose follower and a hydraulic grab machine provided with the hose follower. Background technique [0002] Diaphragm wall hydraulic grab is one of the hydraulic grab machines. It is a basic engineering construction machine with low construction cost and high construction efficiency. Its excavation depth can reach 100 meters. The closing and opening of the diaphragm wall hydraulic grab body is driven by the cylinder on its frame (the cylinder can be called: bucket body opening and closing cylinder). When the hydraulic grab is lifted or lowered, the hose wound on the reel should also be lifted and lowered synchronously with the grab body. How to achieve synchronization is a key technology of the hydraulic grab. [0003] In order to solve the above problems, in the prior art, a pump is used to directly drive a hydraulic motor to drive the hose up and down. At presen...
