Description

[Detailed Description of the Invention] This invention relates to a hoisting rope steady rest device for an elevator.

First, a conventional hoisting rope steady rest device for an elevator will be explained with reference to FIG.

In the figure, reference numeral 1 denotes a car compartment installed in a car frame 1a, and the car compartment 1 is moved up and down within a hoistway 2a by means of a hoisting rope 2 connected to the upper part of the car frame 1a. 3 is the car frame 1a in the hoistway 2a.
A pair of rails arranged at left and right opposite positions, one end of which is fixed to the frame member 5 of the hoistway at approximately the middle of the entire length of the pair of rails 3, and the other end is fixed to the side of the rail 3. A support member 4 is provided that projects horizontally. Reference numeral 6 denotes a steady rest main body for the winding rope that is moved in the vertical direction by a grooved guide roller 7 that engages with the rail 3 and rolls.
The steady rest main body 6 has an annular rope guide 8 in the center thereof through which the hoisting rope 2 passes, supported by support rods 9 at both ends, and guide rollers attached to the ends of each support rod 9. 7 on the mounting plate 7a,
The tip portion 10a is the protruding portion 4 of the support member 4.
An engaging member 10 is provided that protrudes and is fixed so as to engage with a. A wear-resistant rubber 11 is fixed to the inner circumferential surface of the annular rope guide 8 by adhesive or other means to prevent wear of the hoisting rope 2 and prevent collision noise of the hoisting rope 2 during operation. ing. Further, a cushioning rubber 12 is fixed to the engagement surface of the engagement member 10 with the support member 4 so as to reduce the impact of the steady rest main body 6 falling. 13
is a catch installed on the top surface of the car frame 1a,
It is adapted to engage with a seat 14 provided on the support rod 9 of the steady rest main body 6.

In the above configuration, when the car room 1 is located downward, the steady rest main body 6 is locked to the support member 4 attached to the approximately middle part of the rail 3 at the full height of the hoistway, and the hoisting rope 2. The horizontal sway etc. of 2 are prevented by an annular rope guide. Also, the car compartment 1 starts to rise, and the catch seat 1 of the car frame 1a
When the seat 14 of the steady rest main body 6 comes into contact with the steady rest main body 6, the steady rest main body 6 is lifted upward together with the car frame 1a, and descends again following the descent of the car frame 1a.
When reaching approximately the middle part of the rail 3, the tip end 10a of the engaging member 10 of the steady rest main body 6 touches the support member 4.
The hoisting rope 2 is engaged with the protruding part 4a of the hoisting rope 2 and is locked, and further descent is suppressed, so that only the car compartment 1 descends, and the hoisting rope 2
The steady rest is provided approximately in the middle of the hoistway. However, in the steady rest device having the above structure, if the overall weight of the steady rest main body 6 is not increased, the steady rest main body 6 lifted upward by the car frame 1a will cause the car chamber 1 to start descending together with the car frame 1a. However, there was a possibility that the steady rest main body 6 would not descend due to its own weight and would remain above the rail 3. On the other hand, if the weight of the steady rest main body 6 is increased, when the catch seat 13 abuts against the seat 14 and the engagement member 10
The impact force and impact sound when the is locked to the support member 4,
Even though cushioning rubber was provided for each, they ended up being extremely large. Furthermore, when the hoisting rope 2 swings significantly, the surface pressure between the hoisting rope 2 and the rubber 11 provided on the rope guide 8 increases, potentially causing a problem of frictional resistance.

This invention is an attempt to eliminate the above-mentioned drawbacks.The upper part of the car frame of the car room and the hoistway side framework member or rail are provided with a support member and a shock absorber each having a horizontal cross section shaped like a letter, and the steady rest main body Eliminates running resistance, reduces impact force and impact noise,
Furthermore, it is an object of the present invention to provide a steady rest device for a hoisting rope of an elevator in which the frictional resistance and friction of the hoisting rope are reduced by equipping the steady rest main body with a rope guide made of a rotating body.

An embodiment of this invention will be described below with reference to FIGS. 2 to 4.

In the figure, the same reference numerals as in FIG.
The lower ends are fixed to the frame members 5a, 5b, 5c, and 5d arranged in the front-rear and left-right directions through the openings 15b, respectively. Reference numeral 16 denotes a steady rest main body, and this steady rest main body 16 has supporting rods 16a, 16 parallel to the front and back horizontal directions, as shown in FIG.
Consisting of connecting plates 17a and 17b connecting b,
Engagement members 1 for engaging with the hoistway side support member 15 are provided at the left and right ends of each support rod 16a, 16b.
8 are installed respectively. 19 is a rope guide provided in the center of the steady rest main body 16;
The rope guide 19 is connected to the support rods 16a, 16b.
Mounting plates 20a, 20 fixed perpendicularly to
A rod-shaped rotating body 21 with a cushioning material such as rubber attached, which is arranged in a grid shape and rotatably attached to b.
It is composed of a, 21b, 22a, and 22b. 23a and 23b are the car frame 1a of the car room 1;
A car side support member fixed to the upper part of the car and having an upper tapered part 23c and formed in a cross-sectional shape,
Guide elements 24a and 24b for regulating the position of the steady rest main body 16, which are fixed to the center portions of the left and right outer surfaces of the mounting plates 20a and 20b of the rope guide 19, are fitted and supported on the support members 23a and 23b. It's getting old. Reference numeral 25 denotes a shock absorbing device such as an oil damper or an air damper, which is used to reduce the impact of the guide elements 24a and 24b. 26 is the car frame 1a
This is a seat planted in the upper part of the steady rest main body 16 for contacting with the seat 27 of the steady rest main body 16. Note that 15c is a cushioning material such as rubber provided at the bottom of the hoistway side support member 15.

This invention has the above configuration, so when the car compartment 1 is located downward, the steady rest main body 1
6 is supported by the hoistway side support member 15 and is located approximately in the middle of the total height of the hoistway, and the horizontal shaking of the hoisting rope 2 is handled by the left and right, front and rear rod-shaped rotating bodies 21a, 21b, 22a, 22b, and when the car chamber 1 starts to rise, the guides 24a, 24b of the steady rest main body 16
The steady rest main body 16 is lifted upward with the seat 27 fitted into the support members 23a and 23b provided on the upper part of the car frame with the seat 27 in contact with the catch seat 26, and as the car 1 is lowered. At the same time, when it descends to the middle part of the hoistway, the engaging members 18 attached to the tips of the support rods 16a, 16b of the steady rest main body 16 are engaged and held by the hoistway side support members 15 arranged at the four corners, and the lower The lowering of the hoisting rope 2 is regulated, and the rope guide 19 is used to prevent the hoisting rope 2 from steadying. Hoistway side support member 15
It is clear that the effect of reducing impact force and impact noise is improved by providing the shock absorbers 25 on the car-side support members 23a and 23b.

Figure 5 shows another embodiment of this invention.
Due to the effective area of the hoistway, the hoistway side support member 15
This figure shows the steady rest main body 16 when it is impossible to install the steady rest main body 16 in four places. In the figure, the same reference numerals as in FIGS.
Mounting plate 17 to which support rods 16a and 16b are attached
This is a stopper fixed to the outer surface of a and 17b.

This retainer 28 has a recess 28a on its outer end surface, and this recess 28a is installed so as to fit into the rail 3. By providing this stopper 28, only when the steady rest main body 16 is held by the support member 15 located at the center of the total height of the hoistway, the circumferential surface of the recess 28a contacts the rail 3, causing the steady rest main body 16 to come into contact with the rail 3. The steady rest main body 16 plays the role of keeping the vehicle substantially horizontal, and while the steady rest main body 16 is rising or falling together with the car room 1, the steady rest main body 16 is held in a horizontal state so that it does not come into contact with the rail 3, and the steady rest main body 16 16 running resistance does not occur at all.

As explained above, this invention provides a car-side support member that fits and supports the guide for regulating the position of the steady rest main body 16 as a shock absorber on the upper part of the car frame of the car room 1, and also provides a car-side support member in the center of the hoistway. Since the structure is equipped with a shaft-side support member to engage and hold the steady rest main body, the position of the steady rest main body is determined, so there is no need for guide rollers as in the past, and the running resistance of the steady rest main body is reduced accordingly. Even if the weight of the steady rest body is reduced, the problem of only the car chamber being lowered and the steady rest body remaining above can be resolved.
Furthermore, by reducing the weight of the steady rest body and installing a shock absorber above the car frame, it is possible to prevent impact force and noise from the seat of the steady rest body and the seat of the car frame, thereby reducing the impact on the passengers inside the car room 1. Does not cause discomfort. Furthermore, by making the hoisting rope friction surface of the rope guide a rotating body wrapped with a cushioning material made of wear-resistant rubber, etc., it is possible to prevent abrasion of the hoisting rope and wear of the cushioning material. By reducing the frictional resistance between the upper rope and the cushioning material, it is possible to prevent the lightened steady rest main body from slipping out from the hoistway side support member due to the frictional resistance until the car rises and contacts the steady rest main body.
