LIFT AND LIFT WIRE BRACKET

The invention relates to an elevator as defined in the preamble of claim 1 and to a cable fastener as defined in the preamble of claim 5.

5 The narrowness of elevator shafts has become more pronounced as elevator solutions for machine room towers become more common. For efficient space utilization, the elevator ropes are arranged to pass near the elevator rails in the elevator shaft or some other component is located near the elevator rails, such as, for example, the elevator car. Another problem 10 has been the effective implementation of the wire attachment. With current cable mounting solutions, which are usually based on clamping, the installation is slow and cumbersome.

Prior art is described in US Patent No. 4,593,794. This publication discloses a solution illustrating a conventional elevator shaft cable fastening. In it, the T-sectional elevator car rails and counterweight rails are secured to the elevator shaft wall with their own separate guide rails. The disadvantage of this solution, however, is that, for each conductor, a separate conductor bracket is required • »·] · * * that adds the necessary • *» ί ·:! the number of fastening components, such as the number of bolts • ·: and the number of separate wire fasteners. In addition, the large number of «·· components slows down and complicates • 25 the installation of elevator cables. This solution is not optimal due to the large number of components * ·· and their size. In addition, in the fastening according to known technology, the conductors are interconnected. and the distance between the wire mounts is large. In addition, wire fixings according to the prior art are further disclosed in JP 1-271385, JP 6-156925 A and CH 532528 A.

·· *

JP 6-156925 A discloses a solution in which; the width of the wire clip is at the wire attachment point ···. ***. essentially the width of the guide plus the thickness of the guide nails in the bracket ··· 35. JP 1-271385 2 118299 discloses a solution in which two conductors are secured in place with a conductor clip.

The object of the present invention is to eliminate the aforementioned drawbacks and to provide an inexpensive space elevator 5 and a compact conductor bracket which allows to fix several conductors with a single conductor bracket. The elevator according to the invention is characterized by what is shown in the characterizing part of claim 1 and the cable fastener according to the invention is characterized by what is described in the characterizing part of claim 5. Other embodiments of the invention are characterized by what is set forth in the other claims.

With the embodiment of the invention, a wire guide 15 is obtained, by means of which the space between the leads and the wire holder can be reduced. This will free up shaft space for other uses, leaving more space for other elevator components, such as between ropes and rails, and leaving more space for the elevator car, and allows for lay-out solutions that are cost effective. In addition, • · · ^ * · ·. *. Reducing the space between the rails and the cable mounts • · · j ··· allows the use of a particularly small traction sheave • · · ϊ.ϊ ϊ in the elevator machine with the elevator ropes fitted • · · ... · 25 to travel close to the elevator rails for affordable space use · To reach the elevator shaft. These are accomplished by making: **]: a wire bracket of a thin width, preferably substantially the same width as the basket guide j *. width, which makes the runner wider than the bracket ···. 30 only makes the thickness of the wire nails in the cable mount • · ***. The conductor bracket comprises means for securing the body rail ·: * ·· to the body of the conductor bracket. An elevator according to the invention ·· * is characterized in that one. . ·. at least • · · 35 two conductors are secured in place, and that the conductor bracket comprises means for attaching a second conductor to the frame member, and that the 3 118299 means for securing the second conductor comprise at least one common conductive nail portion or at least one common clamping member with tools. The conductor fastener 5 according to the invention is characterized in that it comprises means for securing the second conductor to the body part and that the means for securing the second conductor comprises at least one common conductor nail portion or at least one common clamping member with the carriage conductor attachment means.

In addition, the conductor clamp according to the invention can be used to attach more than one conductor by means of a single conductor clamp, which makes it possible to attach, for example, a basket conductor and a counterweight conductor with a single conductor clamp. This provides additional space in the elevator shaft 15 and, moreover, the wire fastener according to the invention is simple in construction. The light weight and compact size of the conductor fastener components, such as the frame member and the conductor nail components, allow the conductor fastener to contain few parts. The simplicity, light weight and small number of parts of the 20 wire guide fastener according to the invention make the installation, positioning and fastening of the wire considerably easier than • · ♦; · By means of prior art solutions. In addition, in the elevator of the invention, the installation of rails and wire rails • · · ** · / 25 is quick and accurate.

• · * ·· *! The conductor bracket can be made lightweight by making at least ** * ί frame part of a lightweight material, ··· * ... ·, preferably aluminum. Due to its simple construction, light weight and small number of parts, the conductor mount 30 is a cheap assembly.

* ·· · ··· • · * ·. ·. ; The invention will now be described in more detail with the aid of some examples of applications with reference to the accompanying drawings in which: Fig. 1 schematically illustrates an M *, • elevator according to the invention, Fig. 2 Fig. 4 shows a bottom view of one of the inventive conductor retainers and the conductors attached thereto, Fig. 5 shows a frame part of a conductor retainer 5 according to the invention.

Figure 1 schematically shows the structure of an elevator. Preferably, the elevator is a non-engine room elevator in which the drive mechanism 106 is located in the elevator shaft. The elevator shown in the figure is a traction sheave elevator of the highest type. The passage of the elevator hoisting rope 103 is as follows: At one end, the rope is rigidly secured at the top of the shaft in the anchorage point 113 above the movement of the counterweight 102 of the counterweight 102 from where it exits downward the rope 103 further extends upwardly to the drive gear 107 of the drive mechanism 106, which rope extends along the rope groove of the drive wheel. From the traction-20 wheel 107, the rope 103 extends downwardly to the elevator car 101 moving in the elevator car runners 1, lowering it along the pivoting wheels 104 hanging on the elevator car ropes and • tf V! then continuing from the elevator car upwards at the top of the shaft:: *: to the anchorage 114 where the rope 103 is t ·· · •; * · 25 fixed at its other end. Preferred * ·· ·. * ··, ie the anchorage point 113 at the top of the shaft, the drive wheel 107 and the counterweight deflection pulley 109 are disposed so that the • rope portion of the anchorage point 113 corresponds to the weight 102 and the rope portion of the counterweight 102 30 to the traction sheave 107 is substantially parallel to the movement path of the counterweight 102. Similarly, it is * * * an advantageous solution that the anchorage point 114 in the upper *: * section of the traction sheave 107 and the elevator car The runners 104 are disposed with each other such that the rope portion from the attachment point 114 to the elevator car 101 and the rope portion from the carriage 101 to the drive wheel 107 are substantially parallel to the travel path of the elevator car 101. In this case, no additional folding wheels are needed to position the passage of the rope 6118299 into the shaft. Essentially central when the elevator car suspension ropes 104 are disposed substantially symmetrically with respect to the vertical center line through the center of gravity 101 of the elevator car 101. The elevator rails, the counterweight guide rails 2 and the rack rails 1, are secured in place by the guide rails 112 according to the invention.

Preferably, the driving mechanism 106 disposed in the elevator shaft is flat, i.e., thin relative to its width and / or height, or at least slender so that it fits between the elevator car and the elevator shaft wall. As such, the machine may be positioned in other ways, for example, such that the slender machine is partially or completely disposed between an imaginary extension 15 of the elevator car and the shaft wall. It is preferable to place in the elevator shaft the equipment necessary for the power supply of the motor rotating the drive wheel 107 and the equipment necessary for the control of the elevator, both of which may be located on the common dashboard 108 The drive may be geared or non-geared. • * i '. The preferred solution is a permanent magnet motor comprising:. *, Gearless gear. The drive can be mounted • · t J * V in place on the elevator shaft wall, ceiling, rail or • * · 25 rails or other structure such as a beam or • · * ·· * rack. If the elevator were to be made as a sub-machine elevator, then a further possibility of attachment is the floor of the elevator shaft. Figure 1 illustrates a preferred 2: 1 suspension, but the invention can also be implemented in an elevator with a *; the hoisting rope attaches directly without the impeller · »· to the counterweight and the elevator car. Other suspension solutions are also possible in the practice of the invention. The elevator shown in the figure ··· • · '··· * has automatic telescopic doors but; Other types of · »·. *** may be used within the scope of the invention. automatic or swing doors. By means of the conductor fastener 112 according to the invention, the distance between the conductors 1 7 118299 and 2 can be reduced. This allows, for example, the use of a particularly small traction sheave 107 in the drive mechanism 106, preferably in a situation where the elevator ropes 103 are arranged to travel close to the rails as shown in Figure 5. Advantageously, for example, in a situation where the width of the basket guide is 80 mm from the backside, a fastening of about 100 mm wide near or even below the basket guide can be easily achieved by means of a cable clamp according to the invention.

Figure 2 shows a conductor fastener according to the invention and the conductors attached thereto. A T-cross-sectional elevator car guide 1 and a counterweight guide 2 of the elevator are fastened to the body portion 3 of the guide bracket by means of guide nails, of which only the guide nail 4 is shown in Figure 2.

The slider guide 9 of the elevator car passing along the elevator car guide 1 is shown in the figure as a separate component from the elevator car, but in reality it is fitted into the elevator car and / or the elevator car frame by means of a securing member 10. The counterweight guide 2 is shown in Fig. 20 as a hollow T-section guide, but other types of guide may be used in the embodiment of the invention, such as a similar guide wire with a counterweight and elevator car. Also, the slider for the · · «” V counterweight is shown in Fig. • · · 25 as a loose component of the counterweight, but • · *; ·· * is in fact fitted into the counterweight and / or • · t * · *: It is irrelevant to the invention what kind of guides are used to control the elevator car and the counterweight on its track in the guides ** ·,. 30 1 and 2. For example, sliders or roll guides can be used.

Due to the shape of the frame part 3 and the adjustment holes and clamping holes therein, the positioning of the guides is quick and easy to execute precisely, since few parts are needed for adjusting and positioning the guides.

The frame part 3 is secured in place, for example on the wall of the elevator shaft, by means of fastening elements 15,16. Their shape and attachment are not essential to the invention, but are fixed in a manner known per se.

Figure 3 shows the same fastening of two conductors by means of a conductor fastener according to the invention.

The body portion 3 of the guide fastener is cut in the plane x-x shown in Fig. 5. Figure 3 further shows a cross-section of the basket guide 1 and counterweight guide 2 and the fastening element 15 obliquely so that the figure shows how the guides 1 and 2 are attached to the frame member 3. In the example of Figure 3, two guides, the basket guide 1 and counterweight guide 2 cable guide in place. The basket guide 1 20 is secured in place to the frame member by means of guide nails 4 and 5 and the counterweight guide 2 2 is secured in place · *! ·. to the body part 3 by means of guide nails 5 and 6. Thus, by means of the same guide nail 5, 2, both J · V basket guide 1 and counterweight guide 2 are attached, i.e. they have a common guide nail. The guide nails 4 and 5 are tightened in place by the clamping member 7, which is preferably a bolt or a similar clamping member.

In the example solution 9118299 above, only two clamping members, preferably bolts, are required to secure the two guides. When using a cable clamp according to the invention, only as many bolts 5 as there are rails, or even fewer, are needed to secure the rails to the frame member when attaching at least two rails. Prior art solutions required 2 bolts per conductor. Due to the shape of the body and the guide nails, the number of clamping members required can be reduced by 10 compared to the previous one, and the number of parts needed for fixing the guide rails can be reduced.

Fig. 4 is a bottom view of the cable mount according to the invention and the elevator objects which can be fastened therewith. The figure shows how the guides 1 and 2 are fastened to the body part of the guide fastener according to the invention by means of guide nails. Figure 4 shows how the basket guide 1 is secured to the body part 3 by a guide nail 4 which is clamped in place by a clamping member 7.
