Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a diagonal elevator device.

[Conventional technology]

Tail cords for elevators are generally fixed at two points: the power supply end of the control device installed in the machine room and the power receiving end installed on the car side, and the middle part is fixed inside the hoistway so that it can follow the up and down movement of the car. It has a structure that allows it to be hung and moved freely.

[Problem to be solved by the invention]

For this reason, in a diagonal elevator that ascends and descends at a certain angle of inclination, the U-shaped lower part of the tail cord always moves in contact with the hoistway wall, causing equipment in the hoistway to move. There is a good chance that it will get caught, and its protection is an essential condition for forming a diagonal elevator.

SUMMARY OF THE INVENTION An object of the present invention is to provide a diagonal elevator system that is intended to prevent the tail cord from getting caught in tower equipment when the elevator goes up and down.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a tail cord support part projecting from the side of the car, supports a folded tail cord extending from the upper part of the hoistway on this tail cord support part, and A tail cord guide path in which the tail cord is placed at a lower position than the guide rail of the car is provided, and a weight truck is engaged with the folded portion of the tail cord, and the weight is guided along both sides of the tail cord guide path. A track was created for the bogies to run on.

[Effect]

The tail cord is placed in the tail cord guide path at the bottom of the car guide rail, so the tail cord does not get caught on other equipment in the hoistway, and there is no weight on the lower folded part of the tail cord. Since the trolley is engaged to apply tension, the tail cord will not become sagging and fly out from the tail cord guide path and get caught on other equipment.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. The car b is fixed to a support structure k, and the support structure k moves on a guide rail t, which is an elevator track, while sliding on a guide roller u and a guide shoe j.
On the other hand, the counterweight B moves on the track rail i while sliding on the guide roller e and the guide shoe z. Furthermore, the car structure k and the counterweight B are directly connected by a rope f via a sheave C for a hoisting machine (not shown) and a deflection wheel d installed on the floor h of the machine room above the hoistway. It is clear from this that the hoist moves up and down as the hoist sheave C rotates. on the other hand,
Control device a and car b installed on machine room floor h
Since the hoistway wall T is inclined at a predetermined angle, the tail cord g fixed to the hoistway wall T moves up and down while coming into contact with the hoistway wall T, as shown in FIG. In addition, in the figure, S indicates a power receiving end relay box attached to the car, and G is a tail cord support part that protrudes to the side of the car b, supporting the folded side of the tail cord g. . q is an elevator shock absorber installed at the bottom r of the hoistway, and l is a constant gravity applied to the tail cord g so that the tail cord g can move smoothly in parallel with the elevator's ascent and descent.
It is a weight truck configured to hang on m
is a rotating roller that engages with the folded portion of the tail cord g so as not to prevent the tail cord g from moving, and n is a wheel that assists the movement of the weight truck l. Also,
The weight truck l is constructed to move up and down on a predetermined running track p, following the rise and fall of the tail cord g. In addition, a guide path D is provided in which the tail cord g is placed at a lower position than the guide rail t and the track rail i so that the car b, the tail cord support part G on the car side, and the tail cord g can move smoothly. is formed. These guide routes D,
The track rail i is supported by a building-side structure. The traveling trajectory p on which the weight truck l travels is the guide path D of the tail cord g.
located along both sides of the Further, the weight truck l is set to have a weight that allows the tail cord g to move smoothly. In addition, the weight trolley l
As shown in FIG. 5, before descending, it is at the position of the broken line, and after descending, it becomes like the solid line. As shown in Figure 5, when the tail cord g moves on an inclined slope, if there is no guide path D and no load is applied to the tail cord g, it will meander during the descent and pull into nearby equipment in the tower. This results in the tail cord g being cut. However, as in the present invention, the guide path D
By providing a predetermined load and always applying a predetermined load, the tail cord g can always move smoothly within the guide path D. Further, as described above, since the contact portion between the tail cord g and the weight truck l has a rotatable structure, the tail cord g is not damaged. 7th
9 to 9 show other embodiments of the tail cord guide path. FIG. 7 shows a method of constructing a guide path D in a building structure, and FIGS. 8 and 9 show methods of installing a guide path D previously created in a building F, respectively. Moreover, FIG. 7 shows a method of laying a running track L of a weight truck I in a building and constructing a guide path D of a tail cord in the building. Figure 8 shows that the tail cord guide D does not need to be specially constructed, and the running track L of the weight truck L is connected to the building F.
This is a method of forming the structure by laying it on the ground. In this case, it is necessary to increase the diameter of the wheels n of the weight truck L in order to secure a gap between the building F and the weight truck L that allows sufficient movement of the tail cord. FIG. 9 shows a method of installing a workpiece in a building F in which a tail cord guide path D and a running track L of wheels n of a weight truck I are integrated. In particular, in order to prevent the tail cord from coming into contact with the edge of the guide path D and being damaged, the tail cord is designed to be bent.

〔Effect of the invention〕

According to the present invention, as the diagonal elevator moves up and down, the tail cord can move without being caught on equipment in the tower, so it is highly effective in protecting the tail cord of the diagonal elevator.
