JPH079877U - Elevator counterweight - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to enable attachment of a stopper without processing on the counterweight side. [Structure] A detent 5 for preventing the guide rail 1 and the guide device 3 from being disengaged from each other is attached to the counterweight by using a through bolt 4 for fixing a weight. An extending detent piece 5C is formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator counterweight.

[0002]

[Prior art]

 As a conventional device of this type, as disclosed in Japanese Utility Model Application Laid-Open No. 59-120770, there has been proposed a device in which a detent for preventing the guide device from coming off the guide rail is attached to a car. .

[0003]

[Problems to be solved by the device]

 When the retaining device having the above structure is to be attached to the counterweight, it is necessary to form a screw hole for screwing the fixing bolt in the counterweight.

An object of the present invention is to provide a balance weight for an elevator in which a detent can be attached without processing on the balance weight side.

[0005]

[Means for Solving the Problems]

 The purpose of the above is to prevent disengagement between the guide rail and the guide device in an elevator balance weight that is supported by a guide rail vertically installed in the hoistway so as to be able to move up and down through the guide device. Is attached to the counterweight by using through bolts for fixing the weight, and this detent is achieved by forming detents extending from both ends in the vertical direction.

[0006]

[Action]

 As described above, the through bolts for connecting the weights are used to fix the detents to the counterweight in a balanced manner, and the detents formed at both ends prevent the detents from rotating around the through bolts. Since it has been prevented, the balance weight can be equipped with a detent without any processing on the balance weight side.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a plan view of a detent according to the present invention, FIG. 2 is a front view thereof, FIG. 3 is a perspective view of the detent attached to a counterweight, and FIG. 4 is a front view of a main part of the counterweight. FIG. 5 is a plan view of another example of the stopper, and FIG. 6 is a front view.

First, the entire balance weight will be described with reference to FIG. In the figure, 1 is a pair of guide rails installed vertically in the hoistway, 2 is a main weight with a counterweight, 3 is a hanging plate with guide devices formed on both ends of the counterweight, 4 is a main weight 2, and a hanging plate. Through bolts for integrally connecting 3 together, 5 are stoppers that are placed on the hanging plate 3 and fixed by through bolts 4, 6 are oiler mounts, 7 are oilers (oilers), 8 are hanging plates 3. It is the main rope that is tied up.

Next, a main part of the present invention will be described. As shown in FIGS. 1 to 4, the retainer 5 of the present invention has a groove 5A that engages with the guide rail 1, a hole 5B through which the through bolt 4 penetrates, and a detent piece formed by bending both ends at a right angle. 5C is included. Then, as shown in FIG. 3, the stopper 5 is placed on the hanging plate 3 and is attached by the rotation stopper 5C so as to sandwich the hanging plate 3 with the through bolts 4. It is fixed at 3. In this way, since the anti-rotation piece 5C is formed so that the suspension plate 3 is sandwiched between the slip-off stoppers 5, the slip-off stopper 5 rotates about the through-bolt 4 even if the fixing point is only one position of the through-bolt 4. There is no need to do this, and there is no need to perform any processing on the counterweight side. FIG. 5 and FIG. 6 show another embodiment of the retaining member, in which the detent piece 9C of the retaining member 9 is formed by welding. Other configurations such as the groove 9A and the hole 9B are the same as those shown in FIGS.

[0011]

[Effect of device]

 As described above, according to the present invention, the retaining member can be attached without any processing on the counterweight side.
