Description

Roller type abrasion-resistant guide shoe of high-speed elevator

Technical Field

The utility model belongs to the technical field of elevators, and particularly relates to a roller type abrasion-resistant guide shoe of a high-speed elevator.

Background

The guide shoe is one of the most commonly used guide devices for elevators and is a wearing part that is in direct contact with the guide rail. The abrasion condition of the guide shoes influences the running energy consumption and riding comfort of the elevator, and the guide shoes are respectively used in a low-speed elevator, a medium-low-speed elevator and a high-speed elevator according to different running speeds of the elevator, and different types of guide shoes are selected for the elevators with different speeds.

For example, chinese patent publication No. CN211521286U discloses a semi-elastic rolling guide shoe comprising a first sliding member, a second sliding member, a third sliding member and a shoe seat; the third sliding member is provided with an elastic member, and the rolling portion of the third sliding member is in a reciprocating state with respect to the shoe by the elastic member. The semi-elastic rolling guide shoe provided by the utility model saves two elastic parts in the prior art, and the distance between the first sliding part and the second sliding part is smaller than the distance between two corresponding rollers of the rolling guide shoe in the prior art, so that the volume of the rolling guide shoe in the prior art is reduced.

This patent suffers from several drawbacks in use, such as: the device reduces the guide shoe volume through reducing elastic component, but, the stability and the shock-absorbing capacity of the device also reduce greatly, in addition, the device is after long-time use, its gyro wheel takes place wearing and tearing under the effect of frictional force, life is not high, and among the prior art, there is through setting up extra lubricating oil drum in the guide shoe top, lubricate the gyro wheel, but these lubrication components often are huge, and because of its oiling mode exposes, lead to the lubricating oil leakage condition serious, in addition, most guide pulleys on the market all dismantle through loosening fixing bolt one step now and dismantle, this has increased operating time greatly for maintenance personnel's maintenance change's operation. In view of this, we propose roller-type wear-resistant guide shoes for high-speed elevators.
