Problems solved by technology

[0002] In the production process of steel coils, sometimes it is necessary to lift the steel coils. One of the methods is to stir up the steel coils. (commonly known as roll eye), once the adjustment bar is not aligned with the roll eye, a collision accident will occur, resulting in damage to the steel coil or equipment. When there is someone between the adjustment bar and the steel coil, personal injury or death accidents are more likely to occur
The technology currently in use is to install a disc-shaped part on the front end of the adjustment bar, and then set a part on the top of the disc-shaped part that can move radially along the disc-shaped part. The disc-shaped part and the radial part share the function of the tentacles. Before insertion, the radial part of the tentacle and the disc-shaped part together form a contour larger than the shape of the adjustment bar (smaller than the coil eye). Coil strong top, when there is no alignment (or there are people in between), the radial parts protrude due to the elastic force, the front end of the tentacle radial parts collides with the steel coil, and the tentacle and the disc-shaped parts are compressed along the axial direction of the adjustment bar The spring triggers the sensor to sense the signal and protect the equipment or personal safety. The disc-shaped part of this structure needs to rely on the linear guide support to keep its front side perpendicular to the insertion direction. The guide length of the linear guide support is the distance between the collision point and the guide support. When the ratio is close to or less than 2 times the friction coefficient, the sliding pair will self-lock, and the structural failure will not protect it. Therefore, the guide length needs to be as long as possible, which makes the structural length larger. Even so, due to the wear of the guide support , the guide length will gradually become shorter, and eventually self-locking phenomenon may occur, which will not provide protection when an accident occurs, and because the radial part must be kept above the disc-shaped part, the guide support is in the cylindrical guide rod. In some cases, a pair of guides must be used, the structure is complex, and the processing accuracy is high.

Embodiment Construction

[0012] The shape of the disc-shaped part used as the tentacles must be smaller than the shape of the corresponding position of the inserted object, and at the same time need to be larger than the shape of the object inserted later. The shape of the adjustment bar is the shape of the aforementioned equipment used in the production of steel coils, and it can also be applied to The end of the coiling shaft of the uncoiler, taking the above-mentioned adjusting rod as an example, the steel coil has a circular eye, so it is easiest to make the tentacles into a ring. In order to connect the tentacles (1) and the swing plate (2) together , the tentacles (1) also need to contain the parts required for the connection, figure 1 The tentacles (1) of the shown embodiment are like a steering wheel, and it includes a circular ring (hereinafter referred to as the tentacles ring), the spokes supporting the tentacles ring and a link, and the spokes are used to support the tentacles ring, and the...

Abstract

Through arranging a touch sensing element like the function of a cat whisker at the insertion end of equipment, the collision of insertion body to an inserted body can be avoided. An object capable of swing and move is used as a tentacle, a swing angle is converted into displacement, collision is sensed by measuring the displacement, and a sensor can send a message when the tentacle swings laterally or moves axially.

Description

technical field [0001] A special sensor, two objects that are relatively moving and interspersed with each other, especially when they are not allowed to collide with each other, in order to avoid accidental collisions, a touch element with a cat's whisker function can be installed on the front end of the insertion device to sense, Stop in time to avoid accidents, and can be applied to various equipment and equipment. Background technique [0002] In the production process of steel coils, sometimes it is necessary to lift the steel coils. One of the methods is to stir up the steel coils. (commonly known as roll eye), once the adjustment bar is not aligned with the roll eye, a collision accident will occur, resulting in damage to the steel coil or equipment. When there are people between the adjustment bar and the steel coil, personal injury or death accidents are more likely to occur. The technology currently in use is to install a disc-shaped part on the front end of the a...
