Description

Description: TECHNICAL FIELD The present invention relates to a method for assembling a fixed gripping device for a cableway of a carrier using a cableway such as a lift, a gondola, and a monorail used for transporting passengers and cargo. It is about.

(Conventional technology and its problems) In order to move lifts and gondola carrying passengers and cargo, a fixed gripping device that grasps the moving steel rope is used. For example, the fixed gripping device shown in FIGS. 3 and 4 has a long grip 2 and a short grip 4, and a disc spring 8 housed in a spring casing 6 screwed to the long grip 2 causes a pressure pin 10 and a central rod. The short grip 4 is pressed against the long grip 2 via 12 and 12 to grip the steel rope 14. Reference numeral 16 in the figure denotes a long grip 2 and a spring casing 6.
Reference numeral 18 denotes a lock nut. The disc spring 8 is inserted between the flange 20 of the pressure pin 10 and the pressure nut 22, and the pressure nut 22 is prevented from moving by the snap ring 24.

To assemble this fixed gripping device, loosen the lock nut 18 and move it closer to the steel rope, and then first attach the long grip 2 to the steel rope 14.
Spring casing 6 while pressing the disc spring 8
Is screwed into the threaded portion 16 of the long grip 2, and when the steel rope is sufficiently gripped between the long grip 2 and the short grip 4, the lock nut 18 is tightened until it comes into contact with the end surface of the spring casing 6. Thus, the spring casing 6 must be screwed into the long grip while pressing the disc spring 8.
However, since the spring force of the disc spring is very strong, it is very difficult to screw in the screw portion 16 while compressing the disc spring. Therefore, the pressure pin 10 is screwed in, for example, by a hydraulic device to the right side in FIG. 3 while the disc spring is compressed by the tension flange 20. Therefore, an expensive hydraulic device is required and the assembly work becomes expensive. In addition, it is difficult to confirm whether sufficient spring pressure to compress the steel rope has been obtained. If the steel rope is not gripped sufficiently, not only the purpose of transportation will be achieved, but also dangerous.

(Structure of the Invention) In order to solve this problem, a method of assembling a gripping rope device for a cableway according to the present invention includes a fixed long grip for grasping a steel rope, a movable short grip, and spring caging screwed to the long grip, A fixed gripping device for a cableway, comprising: a pressure pin arranged in the spring casing for pressing the short grip against the steel rope; and a spring inserted between the spring casing and the pressure pin. A stop gauge means capable of holding the spring on the pressure pin is detachably provided on the pressure pin in a state close to the state when the rope device grasps the steel rope, and the movable short grip is fixed to the fixed long grip. When the steel rope is gripped between the short grip and the long grip, the stop gauge means is removed and the force of the spring is applied to the movable short grip so that the steel rope is It is characterized by being fixed almost permanently.

(Operation) According to the method for assembling the fixed gripping device of the present invention, since the disc spring and the pressure pin are integrally assembled by the stop gauge means before assembly, it is not necessary to apply a pressing force to the disc spring thereafter. Assembly is very simple as all that is required is to attach the spring casing to the long grip.

(Example) FIGS. 1 and 2 show an example of a fixed gripping device according to the method of the present invention, and the same parts as in FIGS.

In assembling the fixed gripping device by the method of the present invention, a circumferential groove 26 is formed in advance on the pressure pin 10, the disc spring 8 is arranged around the pressure pin 10, and the pressure nut 22 is arranged. The stop gauge 28 is arranged in the circumferential groove 26 of the pressure pin 10 as shown in FIG. This sets the position of the disc spring 8 with respect to the pressure pin 10 when the assembly is completed.

Next, the spring casing 6 is screwed halfway into the long grip incorporating the short grip 4 and the center rod 12, and the pressure pin 10 having the disc spring 8 arranged therein is arranged in the spring casing 6. Next, the spring casing 6 is screwed into the long grip until the steel rope 14 is sufficiently gripped by the long grip 2 and the short grip 4 by the pressing force of the disc spring 8. After that, the lock nut is tightened so as to hit the end surface of the spring casing 6, and the spring casing 6 is fixed to the long grip 2. After that, the snap ring 24 is attached to the inside of the spring casing 6, and the stop gauge 28 is removed.

According to the above-mentioned structure, the pressure pin 10 and the disc spring 8 are integrally assembled in advance. Therefore, in assembling this fixed gripping device, it is not necessary to apply a pressing force to the disc spring, and the spring casing 6 is simply assembled. Assembling is significantly simplified, since it only needs to be attached to the long grip 2.

The stop gauge 28 may be manufactured as a stop gauge 30 obtained by dividing an annular one into two as shown in FIG. 2 (b).

In the assembling method of the present invention, it is preferable that the pressure pin includes a circumferential groove formed in the pressure pin and a stop gauge, and the stop gauge means is constituted by the groove.

In the method of the present invention, not only the above-described assembly is performed on the site where the steel rope is present, but also at the manufacturing site, the pressure pin 10 and the spring casing 6 may be assembled and placed with the disc spring 8 compressed.

(Effect) Since the present invention uses the stop gauge 28 to set the disc spring 8 to the pressure pin in advance and then assembles the spring casing, the assembly is easy, and the assembly at a particularly difficult site is extremely easy. Can be done
