Double-layer walking guide wheel set and electric hoist employing guide wheel set

Abstract

The invention relates to a double-layer walking guide wheel set and an electric hoist employing the guide wheel set. The double-layer walking guide wheel set comprises two hanging plates respectively positioned on two sides of an I-beam and guide wheels which are respectively in bearing connection to the two hanging plates, wherein the guide wheels are mounted on steps of the I-beam. The double-layer walking guide wheel set is characterized in that the guide wheels on each hanging plate comprise an upper guide wheel and a lower guide wheel which are respectively mounted on the upper layer and the lower layer of the I-beam; at least one wheel on at least one hanging plate is fixedly connected with a driven gear in a coaxial side-by-side manner; the at least one hanging plate is in bearing connection with a driving gear which is meshed with all the driven gears simultaneously. The upper guide wheels and the lower guide wheels are arranged, the structure of an upper step and a lower step of the I-beam is fully utilized, the load of each guide wheel is effectively shared, the driving gear can effectively drive the guide wheels to rotate, and a horizontal plate can prevent the whole electric hoist from falling off.

Description

technical field [0001] The invention relates to an electric hoist, in particular to a double-layer walking guide wheel set and an electric hoist using the guide wheel set. Background technique [0002] In the prior art, the electric hoists that use a single I-beam to travel are all set under the I-beam or on both sides of the I-beam, and the electric hoist guide wheels of the above two technical solutions are all mounted on the steps at the lower part of the I-beam. In fact, as long as the support for the weight of the load is the steps at the lower part of the I-beam, the upper structure of the I-beam is not fully utilized. At the same time, when the electric hoist accidentally falls or tilts, the above two technical solutions cannot make full use of the work. The structure of the upper part of the beam is avoided and resolved. At the same time, the structure of the upper and lower layers of the I-beam usually only uses the lower layer. The upper layer is not well utili...
