Problems solved by technology
The rolling guide shoes are installed on the upper and lower beams of the gantry frame of the elevator car. Due to the tolerances of the gantry frame during production and the cumulative tolerance formed during the assembly process, the installation position cannot guarantee the levelness balance
As a result, the verticality of each roller of the guide shoe is deflected, and it is extremely difficult to correct
When the elevator is moving, the rollers rotate in a biased manner, which increases the friction between the rollers and the guide rails, and vibration and noise are also generated. The biased rotation of each roller produces various pulling forces, and the load and consumption of the roller bearings are also greatly increased. At the same time In addition to the vibration of the elevator, the comfort of the ride is also greatly reduced, which makes passengers worry about the safety of the elevator

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] as attached Figure 1 to Figure 5 As shown in the figure, the elevator rolling guide shoe has independent adjustment of the verticality of each roller and double spring damping function. It includes a base frame 1, a roller assembly 2, and a shock absorption assembly 3.
[0029] A. Roller assembly 2:
[0030] The combination is as attached Figure 3A and Figure 3B , each roller is a double bearing design, see the double bearing 2-2 in the figure, and the snap ring 2-3 is used to fix the double bearing 2-2. The wheel hub of roller 2-1 adopts aluminum alloy die-casting molding, is provided with bearing installation hole, snap ring groove. The rim (tyre) adopts new high-resilience polyether polyurethane material, which effectively solves the problem of large compression and poor instant recovery performance after compression of commonly used rubber materials....

The invention provides an elevator rolling guide shoe. The elevator rolling guide shoe comprises a base frame (1), rolling wheel assemblies (2) and shock absorption assemblies (3); each rolling wheel assembly (2) is installed on the corresponding shock absorption assembly (3), and the shock absorption assemblies (3) are installed on the base frame (1); the base frame (1) comprises a guide rail groove (1-1), installing holes (1-2), upper round steel supports (1-3-1), lower round steel supports (1-3-2) and stand columns (1-4); each shock absorption assembly (3) comprises a pressing block (3-1), springs (3-2), a sliding block (3-3), elastic adjustment bolts (3-4) and nuts (3-5) of the adjustment bolts. By means of the the elevator rolling guide shoe, vibration and noise of an elevator can be greatly reduced, people feel more comfortable to take the elevator, operation is smoother, and the purpose of saving energy is achieved.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator rolling guide shoe with independent vertical adjustment of rollers and double spring damping functions. Background technique [0002] In order to improve the ride comfort of elevators, more and more elevators use rolling guide shoes. The rolling guide shoes are installed on the upper and lower beams of the gantry frame of the elevator car. Due to the tolerances of the gantry frame during production and the cumulative tolerances formed during the assembly process, the installation position cannot guarantee the levelness balance. As a result, the verticality of each roller of the guide shoe is deflected, and the correction is extremely difficult. When the elevator is moving, the rollers rotate in a biased manner, which increases the friction between the rollers and the guide rails, and vibration and noise are also generated. The biased rotation of each roller produce...
