Description

SAFETY GEAR- AND GUIDE ARRANGEMENT OF AN ELEVATOR, AND METHOD FOR REPLACING THE GUIDE OF AN ELEVATOR, AND ALSO AN ELEVATOR

The present invention relates to safety gear- and guide arrangement of an elevator as presented in the preamble of claim 1, a method for replacing the guide of an elevator as presented in the preamble of claim 14, and also an elevator as presented in the preamble of claim 22.

Typically in elevators a safety gear is disposed in a safety gear housing in the bottom part of the sling of an elevator car and a bottom guide shoe, e.g. a slide guide, of the elevator car is fitted below the safety gear, which guide shoe guides the elevator car to travel on the guide rails. The safety gear housing must generally be disposed below the floor level of the elevator car, because it takes space in the lateral direction to the extent that it will not fit outside the wall line of the car. The slide guide is normally disposed below the safety gear housing so that it would be easy to replace if necessary.

If the slide guide were disposed above the safety gear housing, replacing it for a new one would be awkward and time-consuming, because the safety gear housing would have to be detached before replacement of the guide. For this reason, the slide guide is therefore generally disposed below the safety gear. A problem in this type of solution, however, is that the slide guide takes up extra valuable space from below the elevator car. In addition, one problem is often that when replacing the slide guide for a new one, it is necessary to adjust the guide and the safety gear to the correct locations with respect to each other after the replacement, which can be awkward and time-consuming and thus also incurs extra costs. The purpose of this invention is to eliminate the aforementioned drawbacks and to achieve a safety gear- and guide arrangement of an elevator that saves space from below the elevator car and also from the interior of the elevator car. The purpose is also to achieve an arrangement and a method, which allow the replacement of a guide easily and quickly. The arrangement of the invention is characterized by what is disclosed in the characterization part of claim 1. Correspondingly, the method according to the invention is characterized by what is disclosed in the characterization part of claim 14. Correspondingly, the elevator according to the invention is characterized by what is disclosed in the characterization part of claim 22. Other embodiments of the invention are characterized by what is disclosed in the other claims.

Some inventive embodiments are also discussed in the descriptive section of the present application. The inventive content of the application can also be defined differently than in the claims presented below. The inventive content may also consist of several separate inventions, especially if the invention is considered in the light of expressions or implicit sub-tasks or from the point of view of advantages or categories of advantages achieved. In this case, some of the attributes contained in the claims below may be superfluous from the point of view of separate inventive concepts. Likewise the different details presented in connection with each embodiment can also be applied in other embodiments. In addition it can be stated that at least some of the subordinate claims can in at least some situations be deemed to be inventive in their own right.

The purpose of the invention is, among other things, to resolve the problems of prior-art solutions with an arrangement, wherein the safety gear housing of an elevator as well as a guide that travels on a guide rail are fitted modularly into the same shared piece and positioned in relation to each other to become a stationary modular structure .

According to the invention the safety gear- and guide arrangement of an elevator, which elevator comprises a car sling and an elevator car installed in the car sling, which elevator car together with car sling is fitted to travel essentially vertically in the elevator hoistway guided by guide rails, comprises at least bottom guide shoes and at least one safety gear housing provided with a safety gear, and in which arrangement the bottom guide shoes and the safety gear housing are fitted to the bottom parts of the car sling, more particularly to the bottom parts of the vertical elements of it, and the bottom guide shoe and safety gear housing on the same side of the elevator are fixed to the same detachably fixed frame structure as each other.

In the method according to the invention for replacing a guide of an elevator, which elevator comprises a car sling and an elevator car fitted into the car sling, which elevator car is fitted to travel essentially vertically in the elevator hoistway guided by guide rails, and at least bottom guide shoes and at least one safety gear housing provided with a safety gear, the bottom guide shoes and the safety gear housings are fitted to the bottom parts of the car sling, more particularly to the bottom parts of the vertical elements of it, and when replacing the guide, the guide together with the safety gear housing is taken off, and the guide is detached from its base and a new guide is fitted into the same place in which the old guide was, after which the guide and the safety gear housing are fixed together, so as to be interpositioned with each other, to the vertical element of the car sling. According to the invention the elevator comprises an elevator car, which is fitted to travel essentially vertically in the elevator hoistway guided by guide rails, and at least bottom guide shoes for guiding the car guided by guide rail, and at least one safety gear housing provided with a safety gear, which bottom guide shoes and safety gear housing are connected to the elevator car to move along with it, e.g. by fixing directly to the elevator car or indirectly via the frame structure or corresponding. The bottom guide shoe of the elevator (on the same side of the elevator) is above the safety gear housing, in which case the components that take the least space are above and the components that take the most space are below, in which case the bottom guide shoe, which takes little space and is to be disposed in the bottom parts of the elevator car can be fitted at the point of (in the vertical direction) the floor level of the car and/or above it.

In one preferred embodiment the safety gear housing of the elevator is below the floor level of the car and the bottom guide shoe of the elevator (on the same side of the elevator) is at the point of and/or above the floor level of the car. In this way advantageous space savings are achieved.

In a second preferred embodiment the bottom guide shoe and safety gear housing on the same side of the elevator are fixed to the same detachably fixed frame structure as each other. In this way the replacement/servicing method of components is facilitated.

In one preferred embodiment the bottom guide shoe of the elevator is fixed above the safety gear housing in the frame structure. In this way the replacement/servicing method of components is facilitated and space usage is advantageous. In one preferred embodiment the safety gear housing is below the floor level of the car. In this way interior space of the car is saved.

In one preferred embodiment the safety gear housing extends to inside the wall line of the elevator car. In this case it is preferred that the safety gear housing is below the guide, more particularly below the floor level of the car. In this way interior space of the car is saved.

In one preferred embodiment the bottom guide shoe of the elevator is at the point of and/or above the floor level of the car. In this way the vertical space that is at the point of the inside spaces of the car in the vertical direction can be efficiently utilized,

In one preferred embodiment the bottom guide shoe of the elevator is a slide guide. In this way advantageous space usage is enabled.

In one preferred embodiment the module comprised of the frame structure, the bottom guide shoe and the safety gear housing is fitted to be pushed upwards from below in connection with fitting the module into place, preferably into a vertical element of the car sling of the elevator, which vertical element is preferably essentially U-shaped in its cross-sectional profile. In this way the replacement/installation into position of components is easy.

One advantage of the arrangement, the method and the elevator according to the invention is that by means of them valuable space is saved from below the elevator car. This advantage is emphasized especially in elevators with little bottom clearance, such as e.g. in elevators in which the hoisting ropes pass below the elevator car. Yet another advantage is that the bottom guide shoes of the elevator car are easy and quick to replace nor do they and the safety gear need to be adjusted after the replacement. A further advantage is that the solution is simple and inexpensive to implement.

In the following, the invention will be described in detail by the aid of a few examples of its embodiments with reference to the attached drawings, wherein

Fig. 1 presents a simplified and diagrammatic rear view of an elevator according to the invention, in which the arrangement according to the invention is used, Fig. 2 presents an oblique side view of an arrangement according to the invention, and Fig. 3 presents a simplified rear view of a safety gear and of the means used for the adjustment of it.

Fig. 1 presents a simplified and diagrammatic rear view of a preferred elevator according to the invention, in which the arrangement according to the invention is used, For the sake of clarity, some parts of the elevator have been omitted from the figure, such as e.g. the hoisting machine and the hoisting roping. The elevator car 1 is fitted inside the car sling 2 and it is fitted to travel essentially vertically to and fro in the elevator hoistway guided by the guide rails 6. The car sling 2 comprises at least a top element 3, a bottom element 4 and also two side elements, i.e. vertical elements 5, which vertical elements 5 are disposed on the sides of the elevator car 1 where there are guide rails 6. The top guide shoes 7 of the elevator car are fixed to the top parts of the vertical elements 5 and the bottom guide shoes 8 of the elevator car to the bottom parts, below which bottom guide shoes are the safety gear housings 9. In this embodiment the bottom guide shoes 8 are sliding guide shoes. The safety gear housings 9 are in the depth direction, i.e. in the direction of each other, so long that the second ends of them extend to inside the wall line of the elevator car

1, for which reason the safety gear housings 9 are disposed below the floor level of the car 1. In the solution presented the bottom guide shoe 8 of the elevator is above the floor level of the car, but it can alternatively be at the point of the floor level or at the point of and above

(extending to above) the floor level

The pulley 11 of the overspeed governor is disposed in the top part of the elevator hoistway and the diverting pulley 12 in the bottom part, and the rope 13 of the overspeed governor is fitted around these pulleys in a loop that is sufficiently taut. The safety gears 9a of the safety gear housings 9 are connected to each other with a synchronization rod 10, to which the rope 13 of the overspeed governor is fixed, e.g. by means of a lever- like fixing means 14. When the movement of the overspeed governor pulley 11 stops in an overspeed situation, e.g. from the effect of centrifugal force, the overspeed governor rope 13 also stops and at the same time pulls via the synchronization rod 10 the safety gears 9a in the safety gear housings 9 into contact against the guide rails 6, in which case movement of the elevator car 1 stops.

Fig. 2 presents a module 15 according to the invention, into which a slide guide 8 and also a safety gear housing 9 are interpositioned with respect to each other. An actual safety gear 9a, which in this embodiment is a roller-type safety gear, is fitted into the safety gear housing 9. The module 15 comprises a frame structure 16, which is essentially U- shaped in its cross-sectional profile and is of e.g. steel in its material. The slide guide 8 is fixed to the top part of the frame structure 16 and the safety gear housing 9 to the bottom part. The vertical element 5 is also essentially U-shaped in its cross-sectional profile, but slightly larger in its dimensions than the frame structure 16 of the module 15 so that the frame structure 16 fits suitably inside the U-profile of the vertical element 5. The bottom part of the vertical element 5 comprises an aperture for the safety gear housing 9, because the rear part of the safety gear housing 9 extends over the rear edge of the U-profile of the vertical element 5 in the direction of the opposite safety gear housing.

The top edge of the frame structure 16 comprises grooves that function as positioning means 18, which are arranged to fit together with the pins that function as positioning means 19 in the vertical element 5. The module 15 is arranged to be fitted into the U-profile of the vertical element 5 such that the module 15 is pushed inside the U- profile of the vertical element 5 from below, until the positioning means 18 and 19 fit together with each other.

The module 15 is dimensioned so that the bottom edges of the module 15 and of the vertical element 5 are essentially on the same vertical plane when the module is in its position. The module 15 is fixed to the vertical element 5 with bolts in their fixing holes 17.

As presented above, the bottom guide shoe 8 of the elevator is fixed above the safety gear housing 9 in the frame structure 16. Thus the safety gear housing 9 can be left below the floor level in the finished elevator and it can be permitted to extend without problem to inside the wall line of the elevator car 1 (more particularly to inside the projection of the cabin space of the car as viewed in the direction of travel of the car) . The safety gear housing does not in this case extend to above the top surface of the floor level, and does not up any interior space of the car. With these arrangements also a guide, more particularly a slide guide, which is typically small in structure compared to a safety gear housing, can extend to the same height as the interior spaces of the elevator car, more particularly such that the bottom guide shoe 8 of the elevator is at the point of (in the height direction) and/or above the floor level of the car. Since a slide guide can easily be formed to be small in size, it can be installed inside the structures of the wall of the elevator car, or outside them such that it does not at its point take up any interior space of the elevator car (i.e. the enclosure of the slide guide or of the safety gear does not extend into the interior space of the elevator car) . Since with the solution presented the slide guide can be disposed at the level of the interior spaces of the elevator car, there is no compulsion to install it below the safety gear and thus space below the elevator car is saved. With these arrangements driving of the floor level of the elevator car very close to the bottom of the elevator hoistway is made possible, which in turn enables an elevator with a very shallow bottom clearance to be made. In this way an elevator can thus be made, in which the bottom of the elevator hoistway does not need to be a lot lower than the lowermost floor level from which the car is stepped into. The module 15 (frame structure 16 with guides and safety gears) is preferably fitted to be pushed upwards into a vertical element (5) from below, which vertical element is preferably essentially U-shaped in its cross-sectional profile, because this facilitates the replacement method.

When the slide guide 8 must be replaced, the module 15 is detached from the vertical element 5, after which the guide is replaced with a new one and the module 15 is fitted and also fixed back into the vertical element 5. The frame structure 16 of the module 15 comprises a certain standardized fixing point for the guide 8, as a result of which the guide 8 settles always into the same location in the frame structure 16 and the interpositioning of the guide 8 and the safety gear housing 9 no longer needs to be adjusted after the replacement. Fig. 3 presents a simplified rear view of one safety gear of an elevator used in the invention and of the means with which the position of it can be adjusted in the lateral direction. The safety gear housing 9 is fitted between spring means 20 and adjustment means 21. The spring means 20 is fixed to the inside edge of the first side of the frame structure 16 and the adjustment means 21 to the inside edge of the second side. The adjustment means 21 is a wedge-like piece and when it is pushed upwards it presses the safety gear housing 9 in the lateral direction towards the spring means 20. The spring means 20 is e.g. a disc spring and it is fitted to press the safety gear housing 9 towards the adjustment means 21. The safety gear housing 9 is thus squeezed between the adjustment means 21 and the spring means 20, and the position of the safety gear housing can be adjusted in the lateral direction by moving the adjustment means 21 in the vertical direction.

With the method according to the invention the guide 8 of the elevator is replaced e.g. as follows. At first all the components that are an obstacle are detached and also the bolts, with which the module 15 is attached to the vertical element 5, that are in the fixing holes 17 are opened. After this the module 15 is pulled downwards out of the vertical element 5. Next, the guide 8 is detached from the frame structure 16 and the new guide is fitted into the same place in place of the old guide. When the new guide is fixed into position, the module 15 is pushed upwards into its position in the vertical element 5 such that the positioning means

18, i.e. grooves, of the frame structure 16 and the positioning means 19, i.e. pins, of the vertical element 5 connect with each other. Finally, the module 15 is fixed to the vertical element 5 with bolts in the fixing holes 17. Likewise all the other components that were detached for the replacement are fixed back. In the method the guide of the elevator is replaced such that the starting situation and end situation are according to Fig. 1. The safety gear- and guide arrangement of an elevator, to which the method for replacement of the guide relates, is preferably of the type described elsewhere in this application, more particularly of the type described in the description of Figs. 1, 2 and 3. With the structure presented, the advantages described earlier are achieved. With the method according to the invention the replacement of a guide can be performed simply and quickly in an elevator, in which the space usage is efficient, more particularly in an elevator in which the parts of the elevator are at the point of and/or above the floor level of the car. More particularly by pushing the frame structure 16 from below it can be moved simply and with few disassembly procedures into such a position that the safety gear housing 9 is below the floor level of the car and the bottom guide shoe 8 of the elevator is at the point of and/or above the floor level of the car, after which the frame structure 16 can be fixed into the vertical element 5. The bottom guide shoe (8) of the elevator is in this case preferably fixed above the safety gear housing (9) in the frame structure (16) , in which case the pushing procedure is easy to perform. It is preferable to leave the safety gear housing (9) below the floor level of the car to save the space of the elevator car, especially when the safety gear housing extends inside the wall line and would take space from inside the elevator car if it was at the level of the interior space of the elevator car.

The elevator according to the invention comprises an elevator car 1, which is fitted to travel essentially vertically in the elevator hoistway guided by guide rails 6, as well as at least bottom guide shoes 8 for guiding the car guided by the guide rails 6, and at least one safety gear housing 9 provided with a safety gear 9a, which bottom guide shoes 8 and the safety gear housing 9 are connected to the elevator car to move along with it, e.g. by fixing directly to the elevator car 1 or indirectly (e.g. via the frame structure (16) or corresponding (2,16)) . The bottom guide shoe 8 of the elevator is above the safety gear housing 9. The safety gear housing 9 of the elevator is below the floor level of the car and the bottom guide shoe 8 of the elevator is at the point of and/or above the floor level of the car. The bottom guide shoe 8 and safety gear housing (9) on the same side of the elevator are fixed to the same detachably fixed frame structure 16 as each other. The bottom guide shoe 8 of the elevator is fixed above the safety gear housing 9 in the frame structure 16. The safety gear housing 9 is below the floor level of the car so that it can extend to inside the wall line of the elevator car 1. The bottom guide shoe 8 of the elevator is at the point of and/or above the floor level of the car, in which case a car structure of the elevator that saves space in the vertical direction is formed. If the safety gear housing 9 is below the floor level of the car and the bottom guide shoe 8 of the elevator is at the point of and/or above the floor level of the car, the best savings in space from the car and from below it are achieved. The bottom guide shoe 8 is preferably a slide guide, in which case it fits well at the point of and/or above the level of the floor of the car without taking up car space. The module 15, comprising the frame structure 16, the bottom guide shoe 8 and the safety gear housing 9, is fitted be pushed upwards into the position of the module from below, preferably into the vertical element 5 of the car sling 2 of the elevator, which vertical element is preferably essentially U-shaped in its cross-sectional profile. In this way the replacement work of the guide and/or safety gear is made easier. The elevator is preferably of the type presented in Fig. 1 and the description of it, and comprises the type of safety gear- and guide arrangement described. The method according to the invention presented elsewhere in this application is advantageous and easy to perform to the elevator. The safety gear- and guide arrangement is preferably according to Figs. 1 and 2 to the description of them. The elevator car 1 of the elevator according to the invention can be fitted inside a car sling 2 consisting of a top element 3, a bottom element 4 and also side elements, i.e. vertical elements 5, but the car and car sling can if necessary also be integrated into each other.

It is obvious to the person skilled in the art that different embodiments of the invention are not limited to the example described above, but that they may be varied within the scope of the claims presented below. Thus, for example, the bottom guide shoe of the elevator can just as well be a roller guide instead of a slide guide.

It is further obvious to the person skilled in the art that the safety gear can instead of a roller-type safety gear be some other safety gear, such as e.g. a wedge-type safety gear. What is essential is at least that the guide and the safety gear housing are positioned with respect to each other to be stationary and that they are fixed to a common frame structure.

Additionally, it is obvious to the person skilled in the art that positioning means of the frame structure can be different to what is described above. It is further obvious to the person skilled in the art that the frame structure of the module can be structurally different to what is described above. It is also obvious to the person skilled in the art that the elevator can be moved with any means whatsoever. Preferably the elevator comprises an electric motor and a traction sheave, as well as hoisting ropes connected to the elevator car for moving the elevator car by means of the electric motor and the traction sheave.
