Description

Technical Field

[0001] The utility model relates to warning alarm equipment, and more specifically, to an electromagnet warning reminder positioning device for a bridge crane. Background Art

[0002] The electromagnets currently used on bridge cranes are all made of an iron core, coil, junction box, lifting lug, and an external iron frame. They can still meet the requirements for lifting large objects and production sites where there are no strict requirements on the surface quality of the objects being lifted. However, in production sites where high accuracy is required for lifting bundles of finished bars and there is a lack of reference objects, it is difficult for the driver to quickly and accurately locate the direction of the electromagnet, especially when there are objects blocking / interfering with the electromagnet on site, making it impossible for the driver to locate it at all. This will seriously affect the lifting rhythm and cause production interruptions. The positioning of the electromagnet requires real-time instructions from ground personnel, which is very time-consuming. Therefore, in order to better solve the problem of electromagnet direction positioning, it is necessary to develop a new electromagnet warning and positioning device for bridge cranes. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an electromagnet warning and reminder positioning device for a bridge crane in view of the deficiencies in the prior art, which is conducive to improving operating efficiency.

[0005] As a further improvement, the end corners at both ends of the positioning strip are arc-shaped structures.

[0006] As a further improvement, a safety distance is provided between the positioning strip and the side wall of the external iron frame.

[0007] As a further improvement, the warning light is a laser light, and the colors of the warning lights at both ends of the cavity are inconsistent.

[0010] Furthermore, the swing angle of the reminder light is 10°-30°.

[0011] As a further improvement, a transparent acrylic plate is installed in the light-transmitting hole.

[0012] Beneficial effects

[0013] The advantages of this utility model lie in the addition of a positioning strip on the outer iron frame of the electromagnet, the surface of which is reflective, and the reciprocating warning light provided within the strip. The combined effects of the reflective layer and the warning light remind the operator to identify and determine the position of the electromagnet during operation. This is particularly useful when the electromagnet is far from the driver's line of sight and visibility is poor. The driver can quickly determine the direction of the electromagnet by visually observing the light from the warning light, minimizing the operator's operating time and improving operational efficiency.

[0019] The present invention will be further described below in conjunction with the embodiments, but this does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0020] See Figures 1-4 The present invention provides an electromagnet warning and positioning device for a bridge crane, comprising two positioning bars 3. The two positioning bars 3 are fixedly mounted on the edges of the top long sides of an outer iron frame 2, with a safety gap 5 provided between the positioning bars 3 and the side walls of the outer iron frame 2. Specifically, the gap 5 can be set to 10 mm, reducing the risk of the positioning bars 3 being scratched when the electromagnet is lifting objects. Both positioning bars 3 are coated with a reflective layer, enabling the bridge crane operator to quickly visually determine the position of the electromagnet. The corners of the positioning bars 3 are curved, preventing them from being caught by long, soft objects. A cavity 14 is defined within the positioning bar 3, with light-transmitting holes 4 formed at each end. Transparent acrylic panels are installed in the light-transmitting holes 4 to prevent dust from entering the cavity. The light-transmitting holes 4 communicate with the cavity 14. Warning lights 11 are provided at each end of the cavity 14. These laser lights are used, and the colors of the warning lights at each end of the cavity 14 are different. For example, one side of the positioning bar 3 uses red light and the other side uses green light, which makes it easy for the driver to quickly identify the direction of the electromagnet and the goods it lifts.

[0021] Considering the presence of numerous equipment and cargo at the lifting site, which could easily interfere with or block the light emitted by warning light 11, this embodiment utilizes a swing drive assembly to mount warning light 11 within cavity 14, with the light outlet of warning light 11 facing light aperture 4. The swing drive assembly drives the warning light to swing back and forth. In this embodiment, the swing angle of warning light 11 is between 10° and 30°, making it easier for the driver to see the light.

[0022] Specifically, the swing drive assembly includes a dual-axis motor 6, a spring 13, and a support rod 10. The warning light 11 is installed in a cavity 14 via the support rod 10, which is hingedly connected to it. The end of the warning light 11 away from the light outlet is connected to the top of the cavity 14 via the spring 13. The dual-axis motor 6 is installed in the cavity 14. The drive shafts at both ends of the dual-axis motor 6 are fixed with extension shafts 8. The extension shafts 8 are connected to the cavity 14 through several bearing seats 7. The ends of the extension shafts 8 are fixedly mounted with cams 9. The cams 9 are located below the warning light 11 and are in contact with it. The dual-axis motor 6 drives the cams 9, so that the warning light 11 can fluctuate with the changes in the position of the undulating part on the cam 9, thereby achieving the up and down swing of the warning light 11, effectively preventing the equipment / cargo on site from blocking / interfering with the light. Among them, the setting of the spring 13 needs to be kept in a compressed state, so that the spring 13 always exerts pressure on the warning light 11 to prevent the warning light from automatically swinging.

[0023] Preferably, a counterweight 12 is fixed to the end of the warning light 11 away from the light outlet, and the counterweight 12 is in contact with the cam 9. The provision of the counterweight 12 not only protects the warning light 11, but also makes the end of the warning light 11 heavier than the end of the light outlet, which can more effectively prevent the warning light from swinging automatically.

[0024] The operating principle of the present invention is as follows: When the operator starts the overhead crane, the device is powered on, causing the warning light 11 to emit light. Simultaneously, the dual-axis motor 6 drives the device to reciprocate up and down. When the operator operates the electromagnet to align the steel material 1, the reflective layer on the positioning strip 3 and / or the warning light 11 can be used to determine the electromagnet's position and orientation, thereby aligning the long side of the electromagnet with the axial direction of the steel material 1, achieving fast and accurate positioning.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
