JPH0510393U - Brake cover mounting method - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to make it possible to attach and detach the cover with one touch, without tools, in order to facilitate inspection of the brakes of electric hoists, which is a work at high altitudes. [Structure] The brake box and cover are connected on one side with a hinge and the other side with a catch clip, and the cushion packing is sandwiched between them for a loose fitting.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a method of mounting a brake cover of an electric hoist.

[0002]

[Prior Art]

 FIG. 4 shows a conventional mounting method disclosed, for example, in Japanese Utility Model Laid-Open No. 50-111590. In the figure, 1 is a brake box, 2 is a cover, and 3 is a bolt for fixing the cover to the brake box. Also, FIG. 5 is an example of the mounting method shown in the example of Publication 57-124135, for example.

The conventional cover is fixed to the brake box by the bolt as described above. In addition, since the electric hoist is a mobile device, and the brake is often sucked and released, the electric hoist is often shocked, and is generally firmly fixed with a few bolts.

[0004]

[Problems to be solved by the device]

 With the above cover mounting method, it is necessary to remove all bolts that are firmly tightened when removing the cover for inspection of the brakes. Also, when reattaching, it is necessary to firmly tighten all bolts. Generally, electric hoists are installed at high places, and it is necessary to take care not to drop the removed cover and bolts at the same time as these works become high places.

In order to solve such a problem, the present invention provides a method of attaching a cover that has sufficient strength against vibration and impact, is easy to attach and detach, and has no detachable parts that may fall. The purpose is to

[0006]

[Means for Solving the Problems]

 The cover mounting method according to the present invention is such that one side of the cover is rotatably connected to the brake box, and the other side is connected with a catch clip, and at the same time, the cushion packing is sandwiched and fastened with a loose fitting. Is the way.

Further, the fitting portion is tapered.

[0008]

[Action]

 With the cover attached as described above, it is possible to open it easily by removing the catch clip and inspect the inside. Has impact.

Further, by tapering the fitting portion, opening and closing of the cover becomes smoother.

[0010]

【Example】

 Example 1. 1 and 2 show an embodiment of the present invention, FIG. 1 is a sectional view in a plane, and FIG. 2 is a front view. In FIGS. 1 and 2, 1 is a brake box, 2 is a cover, 3 is a packing having a U-shaped cross section and is attached to the entire circumference of the cover 2, and the fitting portion where the brake box 1 and the cover 2 are in direct contact is It's a sweet fit. Reference numeral 4 designates an armor fixed to the cover 2, 5 is a mounting metal, 6 is a bolt for fixing the mounting metal 5 to the brake box, 7 is a shaft, and 8 is a stopper fitting for preventing the shaft 7 from coming off. It forms its own hinge. Reference numeral 9 is a catch clip fixed to the cover 2 on the cover 4 and the target position, 10 is a hook of a catch clip, and 11 is a bolt for fixing the hook 10 to the brake box.

In the method of attaching the cover configured as described above, by removing the catch clip 9 from the hook 10, the cover 2 can be opened with the shaft 7 as a fulcrum, and the inside of the cover 2 can be easily inspected. You can Further, in the state where the cover 2 is attached as shown in FIG. 1, the brake box 1 and the cover 2 are fastened via the packing 3, and the packing 3 absorbs small vibrations and shocks. When a larger force is applied, the fitting portion of the brake box 1 and the fitting portion of the cover 2 come into direct contact with each other and receive a force, so that an excessive force is not applied to the packing 3.

Example 2. In the second embodiment shown in FIG. 3, the fitting portion between the brake box 1 and the cover 2 is tapered. With this shape, smoother movement is possible when the cover 2 is opened and closed with the shaft 7 as a fulcrum.

[0013]

[Effect of the device]

 Since this invention is constructed as described above, it has the following effects.

Since the cover can be easily opened and closed, the brake inspection work at high places can be performed quickly and easily.

A tool for opening and closing the cover is unnecessary, and there are no parts to be removed, so that the objects are not dropped or lost.
