Mounting-free electric hoist energy efficiency test bench

Abstract

The invention relates to a mounting-free electric hoist energy efficiency test bench. The test bench comprises parallel support legs at intervals, wherein inner sides of two support legs are respectively equipped with supporting plates, the supporting plates are equipped with a main beam, the upper middle portion of the main beam is equipped with an upper pulley, a trolley track arranged on the ground of the side of a hoist is further comprised, the trolley track is equipped with a running bench scale, the running bench scale is equipped with the electric hoist through a wedge block, a lower pulley is mounted at a lower portion of the main beam, a side pulley is mounted at a lower portion of the electric hoist, the side pulley is arranged at one side of the lower pulley, a suspension hookis guided by the electric hoist, a weight assembly mounted in a ground pit is further comprised, and a wire rope penetrates through a suspension hole of the weight assembly and is finally connected with the suspension hook through the suspension hole and sequentially bypassing the upper pulley, the lower pulley and the side pulley. The test bench is advantaged in that the mounting position of theelectric hoist is ingeniously designed, the structure is simplified, the area of the ground pit is small, mounting and dismounting are quite convenient, professional mounting teams are not needed, andwork reliability is greatly improved.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to an installation-free electric hoist energy efficiency testing platform. Background technique [0002] At present, the electric hoist test bench is basically a "four-beam four-leg bridge test bench", that is, the test bench is composed of two main beams, two end beams, and four outriggers, and the two end beams are connected by welding or bolts. On the outriggers, the two main beams are placed on the two end beams and fixed with bolts. The upper side of the two main beams is arranged with trolley tracks, and the lower side is welded with I-beams. The four beams and tracks are all supported in the air through the outriggers. . Before the electric hoist test, the trolley electric hoist needs to be hoisted above the main girder by the crane in the test workshop and installed on the rails on the upper side of the two main girders; the suspension type electric hoist needs to b...

Problems solved by technology

[0006] (2) Pit and pre-buried are required

[0009] (3) The electric hoist is inconvenient to install

It requires the cooperation of multiple people, involves binding, lifting, installation, commissioning and other processes, and works at heights, making installation extremely inconvenient

[0011] (4) A qualified installation team is required, and testers cannot install by themselves

[0013] Sometimes the installation needs to be outsourced to a professional installation company, so the installation time needs to be coordinated with the installation company, and the installation efficiency is greatly reduced

[0014] (5) Low test efficiency

[0015] It takes a lon
