Combined type rolling guide shoe

Abstract

The invention discloses a combined type rolling guide shoe mainly comprising a guide shoe base frame, idler wheel mechanisms and damping components. The combined type rolling guide shoe further comprises a screen connection plate and screen link stoppers, wherein screens are respectively arranged on the two sides and the back side of the screen connection plate and positioning screw holes are respectively formed in those. Each positioning screw hole is connected with each positioning screw. The front side of the screen connection plate is provided with a guide rail groove. Each screen link stopper, each pressure cover, each limiting screw and each damping component are installed on each positioning screw. Each positioning clamping groove is arranged in one side of each screen link stopper or each of the two sides of each screen link stopper, so that each screen link stopper can be clamped with each screen on the screen connection plate correspondingly. A movable gap is reserved in each positioning clamping groove and each idler wheel mechanism is installed at at least one end of each screen link stopper. The combined type rolling guide shoe has the advantages of being easy to disassemble, assemble and transport, saving storage space, prolonging the entire service life of a product and reducing the maintenance cost. Due to the fact that idler wheels of the idler wheel mechanisms can be positioned and adjusted and absorb shocks in the front, at the back, in the left and in the right, the comfortable stability and safety of an elevator in lifting can be improved.

Description

technical field [0001] The invention relates to the field of elevator accessories, in particular to a combined rolling guide shoe. Background technique [0002] Elevator guide shoes are used as connecting accessories between the elevator car and the elevator guide rail, and mainly play a guiding role. In the field of vertical elevators today, the guide shoes used are roughly divided into two types: sliding guide shoes and rolling guide shoes. The sliding guide shoes mainly lie in the guide rail grooves that interact with the elevator guide rails. It is easy to wear and tear. At the same time, when the sliding guide shoe is used, it is necessary to regularly add lubricating oil to reduce the friction between the guide shoe and the elevator guide rail, which increases the maintenance cost and is not environmentally friendly. Traditional rolling guide shoes are mainly composed of guide shoe base frame, roller mechanism and shock absorbing parts. Compared with sliding guide sho...

In the field of vertical elevators today, the guide shoes used are roughly divided into two types: sliding guide shoes and rolling guide shoes. The sliding guide shoes mainly lie in the guide rail grooves that interact with the elevator guide rails. It is easy to wear and tear. At the same time, when the sliding guide shoe is used, it is necessary to add lubricating oil regularly to reduce the friction between the guide shoe and the elevator guide rail, which increases the maintenance cost and is not environmentally friendly.

Traditional rolling guide shoes are mainly composed of guide shoe base frame, roller mechanism and shock absorbing parts. Compared with sliding guide shoes, it can reduce power consumption, but because the base frame of traditional guide shoes is generally welded structure, the manufacturing cost increases, which is not necessary Environmental protection, when the roller section of the roller mechanism interacts with the elevator guide rail, due to the irregular surface of the elevator guide rail and the limitation of the force direction of the roller, it can only be adjusted forward and backward, so that the contact surface between the roller section and the elevator guide rail is reduced, and the local pressure friction is increased. , it is easy to cause loss of rollers and shorten its service life. At the same time, the force direction of the shock-absorbing parts can only move in parallel. The elevator often has defects such as instability, shaking, and poor stability.
