Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to a suspension feeder hook breakage protection device. Background Technology

[0002] As a core piece of equipment in screening systems in the metallurgical industry, the suspended feeder functions to achieve continuous and uniform material conveying through vibration. Traditional suspended feeders generally employ a structure design where spring hooks connect to the trough, using elastic deformation to buffer vibration impact. However, in actual operation, due to the continuous vibration and swaying during material conveying, the connection between the spring hooks and the trough is subjected to alternating loads for extended periods, leading to frictional wear between the hooks and lifting lugs, which in turn causes metal fatigue and even fracture. Once the hooks fail, the trough tilts or sinks, resulting in a large leakage of material, causing not only production interruptions and raw material waste but also potential equipment damage or safety accidents. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a suspended feeder hook breakage protection device that can prevent the feeder from running out of material when the hook of the suspended feeder breaks, and can also trigger a proximity switch to stop the operation of the feeder, so as to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a suspended feeder hook breakage protection device, including hook brackets set on both sides above the feeder lifting lug, with a ore trough between the hook brackets, a hook at the bottom of the hook bracket, the hook being connected to the feeder lifting lug, a bottom support provided on the hook bracket, the top of the bottom support being fixedly connected to the hook bracket, the bottom of the bottom support being located under the feeder, the bottom of the bottom support being spaced from the feeder, and a proximity switch being provided on the bottom of the bottom support.

[0005] As a further improvement of this utility model: the base is configured as a C-shape, and the base is provided with a first bending part and a second bending part, and the first bending part, the second bending part and the base are integrally fixedly connected.

[0006] As a further improvement of this utility model: the proximity switch is disposed in the second bending portion, and one end of the proximity switch passes through the lower end face of the second bending portion to the upper end face of the second bending portion.

[0007] As a further improvement of this utility model, the distance between the upper end face of the second bend of the base and the feeder is set to 50mm.

[0008] As a further improvement of this utility model: a spring hook is also provided between the hook and the feeder lifting lug, and the hook is connected to the feeder through the spring hook.

[0009] As a further improvement of this utility model: the hook bracket is also provided with a wire rope protection structure, one end of the wire rope protection structure is connected to the hook bracket, and the other end of the wire rope protection structure is connected to the spring hook.

[0010] As a further improvement of this utility model: the length of the base is 1200mm, the length of the first bend and the second bend is 400mm, and the width of the base is 100mm.

[0011] As a further improvement of this utility model: the base is made of Q235 steel with a thickness of 20mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model has a base support under the hook bracket. The base support is a rigid support structure that supports the sinking feeder when the hook breaks, preventing material leakage. In addition, a proximity switch is set at the lower end of the base support. When the hook breaks, the proximity switch will contact the sinking feeder. The proximity switch monitors the position change of the feeder in real time and triggers a stop alarm, which can realize the immediate detection and handling of faults and eliminate the risk of delay in manual inspection.

[0014] 2. This utility model reserves a reasonable distance between the base and the feeder bracket to ensure that the vibration of the feeder will not trigger the proximity switch during normal operation, and will only respond accurately when the hook breaks and causes sinking.

[0015] 3. A spring hook is installed between the hook and the feeder lifting lug. The spring hook absorbs the vibration energy during the operation of the feeder through elastic deformation, reduces friction and wear between the hook and the lifting lug, and extends the service life of the hook.

[0016] 4. The wire rope protection structure serves as a secondary safety measure, maintaining partial connection even when the spring hook fails, preventing the feeder from falling completely. Attached Figure Description

[0026] This utility model provides a suspension feeder hook 5 breakage protection device, including hook brackets 3 arranged on both sides above the feeder lifting lug, with a ore trough 4 between the hook brackets 3, hooks 5 arranged at the bottom of the hook brackets 3, the hooks 5 being connected to the feeder lifting lug, the hook brackets 3 also having a base support 2, the top of the base support 2 being fixedly connected to the hook brackets 3, the bottom of the base support 2 being located under the feeder, the bottom of the base support 2 being spaced from the feeder, and a proximity switch 1 being arranged at the bottom of the base support 2.

[0027] Based on the connection of the hook 5 to the feeder lifting lug, this utility model sets a base support 2 under the hook bracket 3. The base support 2 serves as a rigid support structure, which supports the sinking feeder when the hook 5 breaks, preventing material leakage. Furthermore, a proximity switch 1 is set at the lower end of the base support 2. When the hook 5 breaks, the proximity switch 1 will contact the sinking feeder. The proximity switch 1 monitors the position change of the feeder in real time and triggers a stop alarm, which can realize the immediate detection and handling of faults and eliminate the risk of lag in manual inspection.

[0028] In one embodiment of this utility model, the base support 2 is configured in an U-shape, and the base support 2 is provided with a first bent portion 21 and a second bent portion 22, which are integrally fixedly connected to the base support 2. In this embodiment, the base support 2 has an U-shaped design, including the first bent portion 21 and the second bent portion 22 integrally fixedly connected. The U-shaped design can enhance the bending and torsional resistance of the base support 2, and can effectively withstand the impact when the feeder sinks.

[0029] In one embodiment of this utility model, the proximity switch 1 is disposed within the second bending portion 22, with one end of the proximity switch 1 extending from the lower end face of the second bending portion 22 to the upper end face of the second bending portion 22. In this embodiment, the through-type installation of the proximity switch 1 ensures precise correspondence between the proximity switch 1 and the displacement of the feeder, avoiding false triggering or missed triggering due to vibration.

[0030] In one embodiment of this invention, the gap between the upper end face of the second bent portion 22 of the base support 2 and the feeder is set to 50mm. This invention reserves a reasonable gap between the base support 2 and the feeder bracket to ensure that vibration of the feeder during normal operation will not trigger the proximity switch 1, and will only respond accurately when the hook 5 breaks and causes sinking. In this embodiment, a spring hook 7 is provided between the hook 5 and the feeder lifting lug. The spring hook 7 absorbs the vibration energy during feeder operation through elastic deformation, reducing friction and wear between the hook 5 and the lifting lug, and extending the life of the hook 5.

[0031] In one embodiment of this utility model, a spring hook 7 is also provided between the hook 5 and the feeder lifting lug, and the hook 5 is connected to the feeder through the spring hook 7.

[0032] In one embodiment of this utility model, the hook bracket 3 is further provided with a wire rope protection structure 6. One end of the wire rope protection structure 6 is connected to the hook bracket 3, and the other end of the wire rope protection structure 6 is connected to the spring hook 7.
