Combined type is led boots
Technical field
The utility model more particularly, is led boots about a kind of lift car along the combined type of guide rail movement about a kind of elevator technology field.
Background technology
At present, the jacking equipment elevator that is widely used in vertical transportation means of delivery in the building mainly is made up of towing machine (winch), guide rail, counterweight, safety device (as velocity limiter, safety tongs and energy disperser etc.), signal manipulation system, car and Room door etc.Cage operation wherein is at least two row between the vertical or rigid guideways of inclination angle less than 15 degree, and running velocity can be low speed (1m/s is following), fast (1~2m/s) and high speed (more than the 2m/s).In the operational process, the major part of car and counterweight is led boots and is divided into mainly that sliding type is led boots and roller is led two types in boots.
Sliding type is led boots and is mainly used in the various elevators of running velocity below 1.75m/s, and its structure is that the wear-resisting shoe guide of a spill is contained in and leads in the boots seat, and two sides, the left and right sides contacts with leading boots, and middle one side has the 1-2mm gap with guide pass, and passes through oil lubrication.In use, sliding type is led boots noise and the vibrations bigger owing to cliding friction produces, and the elevator traveling comfort is relatively poor.
It then is to contact (friction of rolling) by three faces of three rollers and guide rail, the elevator of the speed that is mainly used in more than 2.0m/s that roller is led boots.Lead boots with sliding type and compare, friction of rolling is not easy to produce bigger noise and vibrations, and the elevator traveling comfort is higher; But the structure that roller is led boots is comparatively complicated, maintenance difficult, and the cost depletions that causes during operation is bigger.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of operating steadily, and is simple in structure, easy to maintenance, and the combined type that cost is lower and field of application is wider is led boots.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of combined type leads boots, it includes and is used to be installed in the base plate of leading in the boots seat, the side of described base plate one end is provided with the fixed idler whell axle, described fixed idler whell axle is provided with the wear-resisting roll wheel assembly that can contact with guide rail one side roll, the other end of described base plate is provided with the support of outwardly-bent extension and is positioned at adjustment plate on the described base plate side, described support is provided with and is used for the adjustment part that described adjustment plate moves along base plate, can be provided with adjustable roller shaft by the adjustment plate that connecting element is fixed on the described base plate, described adjustable roller shaft be provided with can with the described wear-resisting roll wheel assembly of the opposite side rolling touch of described guide rail, also be provided with the unworn liner between described fixed idler whell axle and described adjustment plate on the side of described base plate.
Described adjustment part is bolt and the nut that cooperatively interacts.
Described connecting element is a bolt.
Also be provided with packing ring between described bolt and the described adjustment plate.
Described unworn liner is the wear resistant nylon liner.
Described fixed idler whell axle and wear-resisting roll wheel assembly are provided with axle with spring collar and hole spring collar.
Described adjustable roller shaft and wear-resisting roll wheel assembly are provided with axle with spring collar and hole spring collar.
Beneficial effect after the employing technique scheme is:
1, combined type of the present utility model is led boots and is led boots with the existing glide formula and compare, and its friction coefficient dwindles greatly, can reduce the vertical and horizontal vibration acceleration of elevator operation, improves the elevator traveling comfort, the vibrations and the noise that produce when reducing to move.Secondly, combined type is led boots and be need not to use oil box to be lubricated, and has reduced environmental pollution.Once more, the shoe guide that existing sliding type is led boots partly is generally about half a year and changes once, and combined type is led the roller replacement cycle of boots at 2 years to 3 years, has simplified the maintenance of elevator greatly.At last, combined type is led boots and be need not to be equipped with rail lubricator and swab case, and its cost is led the 60-70% of boots for existing sliding type.
2, combined type of the present utility model is led boots and is led boots with existing roller and compare, and combined type is led the volume of boots and led 1/4 of boots for existing roller, and is simple in structure, easy for installation, is convenient to maintenance.And the part that contacts with the guide rail end face adopts the form of cliding friction, and loss is less, the cost that combined type is led boots be roller lead boots 1/10, economic performance is higher.
3, in addition, it is very big that combined type of the present utility model is led boots Applicable scope, and the elevator from the villa ladder of 450kg to the various ladder types below the 1600kg all can adopt, and the guide rail model that is suitable for is from various models such as T75-T114.

The specific embodiment
Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.
As shown in Figure 1, combined type of the present utility model is led boots and is included and be used to be installed in the base plate 5 of leading in the boots seat, the side of base plate 5 one ends is provided with fixed idler whell axle 7, fixed idler whell axle 7 is provided with the wear-resisting roll wheel assembly 1 that can contact with guide rail 15 1 side rolls, base plate 5 other ends are provided with the support 3 of outwardly-bent extension and are positioned at adjustment plate 4 on base plate 5 sides, as shown in Figure 2, support 3 is provided with and is used to adjust the adjustment part that plate 4 moves along base plate 5, as shown in Figure 1, described adjustment part is bolt 13 and the nut 14 that cooperatively interacts, adjust and be fixed on the base plate 5 by connecting element again after plate 4 moves to suitable location, as shown in Figure 1, described connecting element is a bolt 11, also be provided with packing ring 12 between bolt 11 and the adjustment plate 4, adjust plate 4 and be provided with adjustable roller shaft 2, adjustable roller shaft 2 be provided with can with the wear-resisting roll wheel assembly 1 of guide rail 15 opposite side rolling touch, also be provided with the unworn liner 6 between fixed idler whell axle 7 and adjustment plate 4 on the side of base plate 5, unworn liner 6 can be the wear resistant nylon liner, not as limit, can provide the product of other any materials of sliding-frictional resistance all can.Unworn liner 6 can be fixed on the base plate 5 by flathead screw 8.Also be provided with mounting hole on the base plate 5.
Also be provided with axle spring collar 9 and hole spring collar 10 on fixed idler whell axle 7 and the wear-resisting roll wheel assembly 1, as shown in Figure 1.In like manner, also be provided with axle spring collar 9 and hole spring collar 10 on adjustable roller shaft 2 and the wear-resisting roll wheel assembly 1.
Combined type of the present utility model is led boots in use, can adopt diameter with contacted two the wear-resisting roll wheel assemblies 1 of the spigot surface of guide rail 15 is the wear-resisting roller of 60-80mm, because being arranged on adjustment plate 4 can move, the gap of two wear-resisting roll wheel assemblies 1 can be adjusted according to the situation of different guide rails, can guarantee that combined type of the present utility model leads boots and the reliability that guide rail 15 spigot surfaces contact, prolong the service life that combined type is led boots greatly.And the part that contacts with guide rail 15 end faces (critical) adopts unworn liner 6 to realize having reduced maintenance and use cost by cliding friction.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
