Embodiment Construction

[0030] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0031] A kind of elevator oil-free self-lubricating guide shoe of this embodiment, as figure 1 As shown, it includes a guide shoe bracket 4, a guide shoe base 1 fixed on the guide shoe bracket 4, a shock absorbing mechanism 2 located in the guide shoe base 1, a shoe liner 5 installed in the shock absorbing mechanism 2 through a bushing 6, And the cleaning brush 3 that is positioned at the guide shoe base 1 top.

[0032] Wherein the guide shoe base 1 is a one-piece sheet metal structure with a U-shaped card slot and a mounting part 11 connected to the guide shoe bracket 4 by using a steel plate at one time, such as figure 2 As shown, the shock absorbing mechanism 2 is installed through the card slot, and the top of the U-shaped card slot in the length direction of the guide shoe base 1 is provided wit...

Abstract

The invention discloses an elevator oil-free self-lubricating guide shoe. The elevator oil-free self-lubricating guide shoe comprises a guide shoe base and is characterized in that the guide shoe baseis provided with a U-shaped clamping groove, a damping mechanism is arranged in the clamping groove and comprises a groove frame with a U-shaped mounting groove, and shoe liners matched with an elevator guiding rail are arranged in the U-shaped mounting groove; multi-dimensional damping balls are arranged on the outer side of the U-shaped mounting groove of the groove frame; and each shoe liner comprises an ultra-high-molecular-weight polyethylene liner body and grease mixed and stored in the liner body. Oil adding devices such as an oil cup on the guide shoe are omitted, thus the structure is simplified, the problems that oil contamination is serious and the top-layer/bottom-pit occupying space is large are solved, and range limitation of guide shoe directional selection is eliminated; awhole guide whip achieves overall force bearing and integrated damping, effective damping is obtained in stereo, multi-dimensional and multi-angle modes, and particularly, the phenomenon of sudden orwavy abnormal vibration can be coped with; and the structure is reasonable and compact, and replacement and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an oil-free self-lubricating guide shoe of an elevator. Background technique [0002] The elevator car is equipped with four sets of guide shoes, which are respectively installed on both sides of the upper beam and under the safety clamp seat at the bottom of the car. Medium deflection or swing. The guide shoe is a sliding part between the elevator guide rail and the car, which can fix the car on the guide rail so that the car can only move up and down. At present, there are mainly two types of guide shoes: sliding guide shoes are used with oil sleeves, and dry rolling guide shoes are used directly. The first form is suitable for medium and low speed elevators, but can withstand large lateral forces; the second form is suitable for It is suitable for all elevator speeds, but the lateral force it can withstand is relatively small. So the guide shoe of the 3rd kind of mode has...
