Liftable worktable

Abstract

The invention discloses a liftable worktable. The liftable worktable comprises a table frame and a table board fixed at the upper end of the table frame, and is characterized by further comprising a hydraulic jack, a fixed pulley, a rolling bearing, a steel wire rope, a channel steel slide way, a movable cross beam, a fixed cross beam and four legs. When the liftable table is ascended, an oil return valve and an oiling hole oil plug of the hydraulic jack are tightened, and a rocking handle is repeatedly pulled and pressed by a hand, so that the piston is lifted, the movable cross beam is lifted, and the steel wire rope on the cross beam is continuously tightened. Along with continuous lifting of the movable cross beam, the steel wire rope pulls the table frame to continuously ascend; and after the ascending is finished, a buckle is used for fastening to prevent the tabletop from shaking. When the worktable is lifted, the buckle is loosened, the oil return valve and the oiling hole oil plug of the hydraulic jack are released, and the hydraulic piston automatically retracts under the effect of gravity of the worktable. Like this, the liftable worktable brings more conveniences and the safety effect to staff when the staff lifts up a heavier object onto the tabletop without force.

Description

technical field [0001] The invention relates to production equipment technology, in particular to a technology for lifting and lowering work tables. Background technique [0002] At present, with the development trend of modern factory production and quality management requirements getting higher and higher, the use of work tables is becoming more and more common. Work tables are mainly used for processing, assembly, maintenance and other work in various processes inside the factory. Existing work tables all have the structure of a table frame and a table board, and this work table is usually fixed. However, many equipment in the factory are relatively heavy, and it is difficult for several people to lift them. For this problem, tower cranes or hoists are usually used for hoisting, but this method is used on large equipment, and our general heavy objects use This equipment is very uneconomical, complicated to operate, expensive, and increases the workload and time of the ...
