Abstract

The utility model relates to a direct-movement elevator high-speed sliding guide shoe which comprises a guide rail and a guide shoe body. The guide rail is arranged on a well wall. The guide shoe body is arranged on an elevator car. A plurality of vent holes are evenly distributed in the inner face of the guide shoe body. An air cushion is fixedly arranged in each vent hole. Each vent hole is communicated with an air inlet in the guide shoe body through a ventilation channel. The air inlet in each guide shoe body is connected with an air pump through a connecting pipe. Each air cushion is in an annular shape and is composed of a wearing ring and a damping ring, wherein the wearing ring is fixed to the damping ring, and the bottom of the damping ring is fixed to the position, corresponding to the corresponding vent hole, of the inner face of the guide shoe body. According to the technical scheme, the friction coefficient between the guide rail and the guide shoe body is greatly reduced, and the distribution range of the air cushions is wide. Even if a pot hole is formed in a certain position of the guide rail, only a certain air cushion leaks and loses efficacy, and the roles of other air cushions can be brought into full play. Due to the damping rings, the impact, caused by the guide rail, on the guide shoe body and the elevator car can be buffered, abrasion is small, and maintenance is convenient.

Description

Craspedodrome elevator high-speed slide is led boots

Technical field

The utility model relates to a kind of sliding guide shoe, particularly relates to a kind of craspedodrome elevator high-speed slide and leads boots.

Background technology

In the prior art, general sliding guide shoe is applied on the elevator of low cruise, and express elevator is difficult for using sliding guide shoe, its major cause is that sliding guide shoe friction coefficient is excessive, it is relatively little that application roller guide shoe is compared sliding guide shoe friction coefficient, but roller guide shoe complex structure, lubricated difficulty, takes up room larger.

As shown in Figure 1, sliding guide shoe 2 inside faces contact with the driving surface of T-shaped guide rail 1, there is lubricating oil to spread upon guide rail 1 surface, reduce and lead friction between boots 2 and guide rail 1, although that sliding guide shoe 2 has lubricating oil to do is lubricated, but in the time running at high speed, lead boots 2 and contact or clash into the strength grow on guide rail 1 surface, lubricating oil oil film is crashed through, and lubricant effect declines, and easily produce temperature rise, further reduce the lubricant effect of lubricating oil.

Utility model content

In view of this, main purpose of the present utility model is to provide a kind of craspedodrome elevator high-speed slide to lead boots, pass through the technical program, adopt pressurized air to blow into air cushion, air cushion outlet and near the air film that forms of guide rail surface, stop air cushion directly to contact with guide rail, greatly reduce guide rail and lead the friction coefficient between boots, and gas can be taken away a large amount of heats, be of value to air film and generate, to meet the needs of craspedodrome elevator high-speed cruising.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of craspedodrome elevator high-speed slide leads boots, include guide rail and lead boots, described guide rail is arranged on well enclosure, leading boots is arranged on lift car, described leading is evenly distributed with respectively several vents on boots inner face, on each vent, be fixedly installed respectively air cushion, each vent is connected with the admission port of leading on boots through air passage respectively, and each admission port of leading on boots is connected with air pump by connection pipe respectively.

Described air cushion is ring-type, is made up of flow ring and shock absorbing ring, and described flow ring is fixed on shock absorbing ring, the bottom of shock absorbing ring be fixed on the leading on boots inner face of corresponding vent locations.

Adopt the beneficial effect after technique scheme to be: a kind of craspedodrome elevator high-speed slide is led boots, pass through the technical program, the friction coefficient that makes guide rail and lead between boots reduces greatly, air cushion distributes wide, even if there is hollow in somewhere on guide rail, also can only cause certain air cushion gas leakage malfunctioning, other air cushions still can intactly play a role, shock absorbing ring can buffer guide rail to leading the impact of boots and lift car, wear and tear little, easy to maintenance.

In figure, 1 guide rail, 2 is led boots, 3 vents, 4 air cushions, 5 air passages, 6 admission ports, 7 connection pipes, 8 air pumps, 9 flow rings, 10 shock absorbing rings.

Detailed description of the invention

Below in conjunction with accompanying drawing, specific embodiment in the utility model is described in further detail.

As shown in Fig. 2-Fig. 4, the craspedodrome elevator high-speed slide that the utility model relates to is led boots, include guide rail 1 and lead boots 2, described guide rail 1 is arranged on well enclosure, lead boots 2 and be arranged on lift car, described in lead on boots 2 inner faces and be evenly distributed with respectively several vents 3, on each vent 3, be fixedly installed respectively air cushion 4, each vent 3 is connected with the admission port 6 of leading on boots 2 through air passage 5 respectively, and each admission port 6 of leading on boots 2 is connected with air pump 8 by connection pipe 7 respectively.

Described air cushion 4 is ring-type, is made up of flow ring 9 and shock absorbing ring 10, and described flow ring 9 is fixed on shock absorbing ring 10, the bottom of shock absorbing ring 10 be fixed on the leading on boots 2 inner faces of corresponding vent 3 positions.

As shown in Figure 5, in the time that air pump 8 is worked, pressurized air is through admission port 6, air passage 5 and vent 3 blow into air cushion 4, flow ring 9 outlets and guide rail 1 near surface of air cushion 4 form air film, stop the flow ring 9 of air cushion 4 to contact with guide rail 1, the flow ring 9 of air cushion 4 and guide rail 1 the closer to, gas pressure intensity is higher, thereby play and stop guide rail 1 and lead the direct of boots 2 and contact, the friction of gas is much smaller than lubricating oil, can take away again heat simultaneously, under air film generates, meet the needs of high-speed cruising, in the time that elevator stops, air pump 8 quits work simultaneously, air cushion 4 can prevent that guide rail 1 from directly contacting and clashing into the inner face of leading boots 2 by actv..

The above, be only better possible embodiments of the present utility model, not in order to limit scope of the present utility model.
