Abstract

The utility model relates to an idler wheel guide shoe which is mainly used for a medium-speed elevator and a high-speed elevator with the speed V which is larger than or equal to 1m/s and smaller than or equal to 5m/s. Idler wheels are arranged on positions where two side faces of a guide rail contact the idler wheel guide shoe, a front contact portion is provided with a sliding shoe guide, and initial pressure of a pair of the idler wheels on the side faces is formed through adjustment of compression amount of a spring on an idler wheel guide rod. The idler wheels of the idler wheel guide shoe and the shoe guide of the sliding guide shoe are combined to use, namely, use conditions of the guide shoe of the medium-speed elevator with the speed between 1.0m/s and 2.0m/s and the guide shoe of the high-speed elevator with the speed larger than or equal to 2.0m/s are integrated. The range of the use speed is wide, and the idler wheel guide shoe is abrasion-resistant, low in friction, low in noise, low in fault rate, and can serve as a preferential part of the guide shoe of the medium-speed elevator and the guide shoe of the high-speed elevator for a whole elevator factory.

Description

Roller guide shoe

Technical field

The utility model relates to the elevator roller guide shoe, is mainly used in the middle and high fast elevator of speed 1m/s≤V≤5 m/s.

Background technology

All belong to easily-consumed products no matter lead boots sliding guide shoe or roller guide shoe, and its unit price is than higher, the operation and maintenance cost that causes to the user is than higher, and each manufacturer all constantly drops into the development that technical force carries out economical roller guide shoe, and it is wider that the direction of its research is still developed operating speed, price is more economical, wear-resisting, low friction, low noise, the roller guide shoe that fault rate is low, thus lead the preferred components of boots as whole terraced factory middling speed ladder and high speed ladder.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, processes easyly, moves more steadily, and repair and maintenance are convenient, the roller guide shoe that Applicable scope is wider.

The utility model is with the use that combines of the shoe guide of the roller of roller guide shoe and sliding guide shoe, promptly taken into account middling speed ladder (1.0 ∽ 2.0m/s) and at a high speed ladder (〉=2.0m/s) lead the boots condition of service, operating speed are wider, and had the advantage of roller guide shoe, and wear-resisting, low friction, low noise, fault rate is low, for whole terraced factory, can be used as in middling speed ladder and the terraced at a high speed preferred components of boots of leading.

What the utility model will be provided with the place of two contacts side surfaces of guide rail is roller, and the setting of the place of positive contact is the slip shoe guide, the initial pressure of a pair of pair of rollers guide rail in side is to be undertaken by the compression of spring amount of regulating on the roller pilot bar, the contact surface of pair of rollers guide rail should be not crooked, should keep evenly vertical the contact with guide pass on whole wheel rim width.

The technical solution adopted in the utility model is as follows: roller guide shoe comprises roller, roller shaft, control stalk, pilot bar, stop nut, spring, boot of elevator, shoe guide and U type frame.

Two rollers are separately fixed on the control stalk by roller shaft, shoe guide by screw retention on boot of elevator, two rollers and shoe guide are " product " font and distribute, just in time contact two sides and the front of guide rail, adjust the compression of spring amount in advance by stop nut and control the initial pressure equilibrium that roller contacts with guide rail, when car is rocked by force unbalance, two rollers drive control stalk around A, the B point is done small size swing, compression spring, buffer action is played in the distortion of spring, and the shaking amplitude of car also can diminish like this, leads boots and also can normally roll.

That shoe guide uses is PA6, has higher resistance to abrasion, material source is wide and replacing is convenient, its contact be the front of guide rail, with guide pass distance be 0.5mm because this design of car, even it is stressed, we on the line direction of two guide shoe base liners, do not have undue fierceness yet and rock, so can use the nylon shoe guide to replace roller in the past, cost-cutting.

What roller used is that polyurethane is injection molded, wraps up the thick rubber of 15mm thereon, requires wear-resistingly, and antiageing has the certain rigidity requirement, and not only moulding is simple for it, low price and can satisfy the elevator traveling comfort and the noise reduction requirement.

Description of drawings

Fig. 1 is the utility model roller guide shoe structural representation;

Wherein: 1-roller, 2---roller shaft, 3-control stalk, 4-pilot bar, 5-stop nut, 6-spring, 7-boot of elevator, 8-shoe guide, 9-U type frame.

The specific embodiment

As shown in Figure 1, the utility model comprises roller 1, roller shaft 2, control stalk 3, pilot bar 4, stop nut 5, spring 6, boot of elevator 7, shoe guide 8 and U type frame 9 compositions; Roller 1 is assemblied in roller shaft 2 and is fixed on the control stalk 3, control stalk 3 together with roller 1 and roller shaft 2 by being bolted on the boot of elevator 7, pilot bar 4 passes control stalk 3 and is connected on the U type frame 9, two extended distances that roller 1 forms about being used to regulate, shoe guide 8 and U type frame 9 are fixed on the boot of elevator 7 together, spring 6 is controlled its stroke by stop nut 5, passes control stalk 3 and is installed on the U type frame 9.

About the shoe guide left-right symmetric, its symmetry is very important in shoe guide the place ahead for two rollers, and whether the friction that can influence itself and guide rail is even, and behind roller stress, spring generation deformation absorbs most energy, makes car become steady.
