Description

Hanging device

The present invention relates to a hanging device, such as for construction, factory handling or other engineering, etc., wherein the hanging device can be fixed or can be combined with a construction vehicle.

Suspension devices are often used on construction sites or other construction applications, such as lifting vehicles to lift steel frames from the ground to another location. When the steel frame is lifted, the steel frame is still in danger of falling, so a certain area below is exposed to danger.

The traditional way is to try to clean up (to avoid people in certain areas) dangerous areas. When the steel frame moves to another location for a considerable distance, the clearance area needs to be larger.

The main object of the present invention is to provide a suspension device having a warning function.

Another main object of the present invention is that when the hanging device has a load, the hanging device can automatically issue a warning, and if there is no load, the hanging device does not issue an alarm.

To achieve the above object, the hanging device of the present invention comprises a spreader and a warning light device.

The spreader is used to hang the load, and the warning light device is combined with the spreader. police The light indicating device includes at least one light emitting module, and when the hanging device suspends the load, the warning light device projects a light to a ground for warning.

According to an embodiment of the invention, the light is projected onto a ground such as annular light, point-like annular light, or uniform light or the like.

According to an embodiment of the invention, the warning light device includes a load sensing device such that when the spreader hangs the load, the load sensing device activates the at least one light emitting module to emit light

In order to enable the reviewing committee to better understand the technical contents of the present invention, the preferred embodiments are described below.

Referring to FIG. 1, the work vehicle 95 (ie, the crane) is provided with a hanging device 1. The hanging device 1 includes a conventional spreader 20. In the embodiment, the spreader 20 includes a hook 21, a hanger 22 and a sling 23. The hook 21 is connected to the hanger 22 through the sling 23, and the hook 21 Used to hang a load 90 (such as a steel frame).

The invention is characterized in that the hanging device 1 further comprises a warning light device 10, the warning light device 10 projects a light 16 to a ground 99 for warning purposes, and the warning light device 10 is disposed above the hook 21 in the embodiment. .

As shown in FIG. 2 , the warning light device 10 is provided with at least one light-emitting module 11 . In the embodiment, the light-emitting module 11 has a plurality of light-emitting modules 11 , such as a laser light module that projects directional light, or a non-projection light. Directional light LED light module.

3 is a first embodiment of the present invention relating to the projection light of the warning light device 10: annular light 16a. In order to create the effect of the annular light 16a (around a ring of light, which may be circular, or other shapes), it is recommended that the plurality of light-emitting modules 11 employ a laser light module, and each of the laser light modules projects a small arc of light. 161a (each of the laser light modules includes an optical module that converts the point light source into a small arc of light, which is a conventional technique), and a plurality of curved light beams 161a are projected by a plurality of laser light modules. The annular light 16a is projected.

4 is a second embodiment of the present invention relating to the projection of light by the warning light device 10: point-like annular light 16b. It is recommended that the plurality of light-emitting modules 11 use a laser light module, each light-emitting module 11 projects a point light 161b, and a plurality of dot-shaped lights 161b constitute a point-shaped annular light 16b.

5 is a third embodiment of the present invention relating to the projection of light from the warning light device 10: uniform light 16c. It is recommended that the plurality of light-emitting modules 11 use LED light modules or other divergent lights. Of course, if the illumination module 11 uses a high-light illumination, the illumination module 11 can be as long as one.

6 is a cross-sectional view showing the internal structure of the warning light device 10 of the present invention.

The inside of the warning light device 10 further includes a load sensing device 13 . The load sensing device 13 includes a spring 131 and a touch switch 132 . The spring 131 is connected to the hook 21. When the hook 21 has the load 90, the spring 131 pulls down and touches the touch switch 132 (the switch is turned down), so that the battery 14 supplies power to the light-emitting module 11; when there is no load 90, The spring 131 comes back to touch the touch switch 132 (the switch is up), so that the battery 14 stops supplying power to the light-emitting module 11. In this embodiment, the light-emitting module 11, the battery 14, and the touch switch 132 (through the electric wire 17) are electrically connected to the circuit board 15. Since the circuit structure is a conventional technology, the detailed principle thereof will not be described again.

To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examination and express the patent as soon as possible. However, it should be noted that The various embodiments described above are merely illustrative for the purposes of illustration, and the scope of the invention is intended to be limited by the scope of the claims.
