Problems solved by technology

[0006] Among these methods, in the method of increasing the size of the guide rail, not only the portion to which the rope supporting device is fixed, but also the entire guide rail becomes larger in size, and thus the cost becomes higher.
Also, sometimes the support span L1 cannot be reduced due to architectural constraints
In addition, when L0 is increased by increasing the length of the columnar body, depending on the elevator, it may interfere with the upper and lower rail brackets.

Embodiment approach 1

[0032] figure 1 It is a perspective view showing a schematic configuration of a machine-room-less elevator according to Embodiment 1 of the present invention. A flat first base 2 and an elongated flat second base 3 with one end in contact with the first base 2 are fixed to the floor surface of the pit of the hoistway 1 .

[0033] A traction frame 5 is fixed to the first base 2 via a pair of traction frames 4 a and 4 b. A traction machine 6 is fixed inside the traction frame 5 . As the hoisting machine 6, a thin hoisting machine whose axial dimension is smaller than the dimension perpendicular to the axial direction is used.

[0034] Furthermore, the hoisting machine 6 has a driving sheave 7 and a hoisting machine main body 8 . The hoisting machine main body 8 has a hoisting machine motor that rotates the driving sheave 7 and a hoisting machine brake that brakes the rotation of the driving sheave 7 . A control panel (not shown) for controlling the hoisting machine 6 is ins...

Embodiment approach 2

[0055] Next, Figure 5 It is a perspective view which shows the suspension body support apparatus which concerns on Embodiment 2 of this invention. In Embodiment 1, the extension part 23b is fixed to the car guide rail 13a by the reinforcing member rail fastener 27 which consists of a bolt and a nut. On the other hand, in Embodiment 2, a plurality of (a pair of) rail clips 28 are used as reinforcing member rail fasteners. Furthermore, the rail clamp 28 receives the load in the horizontal direction caused by the bending moment, and the main body rail fastener 25 receives the load in the vertical direction. Other structures are the same as those in Embodiment 1.

[0056] According to such a structure, it is not necessary to open a hole for fixing the reinforcement member 23 to the car guide rail 13a in the car guide rail 13a, and cost can be reduced. And, by forming the fastener insertion holes 23c, 23d for fixing the reinforcing member 23 to the rail fixing portion 22a as lo...

Embodiment approach 3

[0058] Next, Figure 6 is a perspective view showing a suspended body support device according to Embodiment 3 of the present invention, Figure 7 is viewed from the back side Figure 6 The perspective view of the main part of the suspended body support device, Figure 8 is showing Figure 6 A perspective view of the reinforcement member 23. In Embodiments 1 and 2, one reinforcement member 23 is disposed on each of the upper and lower sides of the suspension body supporting device main body 22 . On the other hand, in Embodiment 3, no reinforcing member 23 is arranged above the suspended body supporting device main body 22 , and two reinforcing members 23 are arranged below the suspended body supporting device main body 22 .

[0059] A pair of rail clip fastener insertion holes 23f are provided in each of the reinforcement member main portion 23a and the extension portion 23b. Rail clip fasteners 29 for fastening the rail clips 28 pass through the respective rail clip fastene...

Abstract

The invention provides an elevator and a hanging body support device thereof. The cost is prevented from being increased, and stress generated on a guide rail due to a bending moment caused by a load of a hanging body is reduced. The hanging body support device (21) is provided with a hanging body support device main body (22), and a pair of reinforcing parts (23) which are fastened on two ends of the hanging body support device main body in the vertical direction. The hanging body support device main body (22) is provided with a tabulate rail fixing part (22a) fixed on a car guide rail (13a), and a hanging body part (22b) which horizontally protrudes from the central part of the rail fixing part (22a) in the vertical direction towards one side. Each reinforcing part (23) is fastened on the end of the rail fixing part (22a) and transmits loads in the horizontal direction from the rail fixing part (22a).

Description

technical field [0001] This invention relates to a suspended body support device that supports a suspended body at a position deviated from a guide rail, and an elevator using the suspended body support device. Background technique [0002] In a conventional rope support device for an elevator, a columnar body is attached to a guide rail via first and second fulcrum bodies provided at both upper and lower ends thereof. A rope end fixing member is fixed to the columnar body by welding or the like. The rope end fixing part protrudes horizontally from the columnar body to the side. A plurality of ropes are connected to the rope end fixing part by means of a plurality of fasteners. In addition, a support member is fixed on the guide rail, and the support member only supports the load in the vertical direction from the columnar body. The lower end of the column is in contact with the upper end of the supporting member (for example, refer to Patent Document 1). [0003] Patent...
