Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal detection brackets for car tippers, and in particular relates to a horizontal detection limit bracket for car tippers. Background Art

[0002] The car tipper is the main equipment of the fuel system of a coal-fired power plant. It bears the heavy responsibility of loading and unloading incoming coal trains, so the safety and reliability of the car tipper system in operation is particularly important. The car tipper is divided into two working modes during operation: forward tipping and reverse tipping. Both modes require the car tipper to be driven by a 380V motor. When the car tipper returns to a horizontal position after tilting the material, it needs to be tested with a horizontal limit to ensure that the car tipper track is in a horizontal position. Otherwise, it is easy to cause major safety accidents such as car derailment. However, when the car tipper platform is loaded with a heavy vehicle, a slight lateral offset will occur. Although this offset does not affect the longitudinal alignment of the track, it often causes the horizontal limit switch to be scratched or the gap is too large, and electromagnetic induction cannot detect the fault. Utility Model Content

[0003] The utility model aims to provide a horizontal detection limit bracket for a tipping machine to solve the technical problem that a slight lateral deviation will occur when a heavy vehicle is loaded on the tipping machine platform, which will cause the horizontal limit switch to be scratched or the gap to be too large, resulting in electromagnetic induction failure.

[0004] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a horizontal detection limit bracket of a dumper, comprising an electromagnetic sensor bracket and a magnet bracket arranged on one side of the electromagnetic sensor bracket, the electromagnetic sensor bracket comprising a first fixed plate, one side of the upper side of the first fixed plate is connected to a first vertical plate through a hinge, one side of the first vertical plate is provided with an elastic component for driving the first vertical plate to reset, and a first arc ring is fixedly connected to the upper side of one side of the first vertical plate;

[0005] The magnet bracket comprises a second fixing plate, a second vertical plate is fixedly connected to the upper part of one side of the second fixing plate, and a second arc-shaped ring is fixedly connected to the upper part of one side of the second vertical plate.

[0006] Preferably, a connecting plate is fixedly connected to the other side above the first fixing plate, the connecting plate is connected to the elastic component, and an electromagnetic inductor is provided on the first vertical plate.

[0007] Preferably, the connecting plate and the first vertical plate are both provided with a first through hole, and the electromagnetic inductor is fixed to the first vertical plate through the first through hole.

[0010] Preferably, the second vertical plate is provided with a second through hole and an iron block, and the magnet block is fixed to the second vertical plate through the second through hole.

[0011] The utility model of a tipping machine horizontal detection limit bracket has the following advantages:

[0012] The horizontal detection limit bracket of a tipping machine is configured with a first vertical plate, a first arc ring, an electromagnetic sensor, an elastic component and a second arc ring so that the first arc ring and the second arc ring are in contact with each other to prevent the detection end of the electromagnetic sensor from being scratched. When the electromagnetic sensor is far away from the magnet block, the first arc ring and the second arc ring are not in contact. The spring drives the electromagnetic sensor to slightly approach the magnet block through the first vertical plate to prevent the electromagnetic sensor from failing to detect the magnet block when the electromagnetic sensor is far away from the magnet block.

[0025] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 4As shown, a horizontal detection limit bracket of a car tipping machine of the utility model comprises an electromagnetic inductor bracket 1 and a magnet bracket 2 arranged on one side of the electromagnetic inductor bracket 1, the electromagnetic inductor bracket 1 comprises a first fixing plate 11, one side of the upper side of the first fixing plate 11 is connected to a first vertical plate 13 through a hinge, the other side of the upper side of the first fixing plate 11 is fixedly connected to a connecting plate 12, an elastic component 17 for driving the first vertical plate 13 to reset is arranged between the connecting plate 12 and the first vertical plate 13, an electromagnetic inductor 16 is arranged on the first vertical plate 13, a first arc ring 14 is fixedly connected to the upper side of the first vertical plate 13 away from the connecting plate 12, and the first arc ring 14 is used to protect the electromagnetic inductor 16;

[0027] The magnet bracket 2 includes a second fixing plate 21 , a second vertical plate 22 is fixedly connected to the upper side of the second fixing plate 21 close to the first vertical plate 13 , a second arc ring 23 is fixedly connected to the upper side of the second vertical plate 22 close to the first vertical plate 13 , and the second arc ring 23 corresponds to the first arc ring 14 .

[0028] like Figure 2 and Figure 3 As shown, the connecting plate 12 and the first vertical plate 13 are both provided with a first through hole 15 , the electromagnetic inductor 16 is fixed on the first vertical plate 13 through the first through hole 15 , and the side of the first arc ring 14 close to the magnet bracket 2 exceeds the detection end of the electromagnetic inductor 16 .

[0029] like Figure 2 As shown, the elastic component 17 includes fixing blocks 171 respectively fixedly connected to the upper sides of the connecting plate 12 and the first vertical plate 13 facing each other, and a spring 172 is provided between the two fixing blocks 171 , and the spring 172 is used to push the first vertical plate 13 .

[0030] like Figure 2 and Figure 4 As shown, the electromagnetic inductor bracket 1 is fixed on the tipping machine through a first fixing plate 11 , and the magnet bracket 2 is fixed on the non-tipping machine platform through a second fixing plate 21 .

[0031] like Figure 4 As shown, the second vertical plate 22 is provided with a second through hole 24, and a magnet block 25 is provided in the second through hole 24. The magnet block 25 is fixed to the second vertical plate 22 through the second through hole 24, and the distance between the second arc ring 23 and the second vertical plate 22 is greater than the distance between the magnet block 25 and the second vertical plate 22.

[0032] like Figure 2 and Figure 4 As shown, the first fixing plate 11, the connecting plate 12, the first vertical plate 13, the first arc ring 14, the second fixing plate 21, the second vertical plate 22 and the second arc ring 23 are made of martensitic stainless steel to prevent the bracket from rusting and deforming.

[0033] In summary, the device is installed on both sides and the middle position of the tipping machine. When the tipping machine is working, it drives the electromagnetic sensor bracket 1 to flip. When the tipping machine is reset, it drives the electromagnetic sensor bracket 1 to reset. At this time, the first arc ring 14 contacts the second arc ring 23, and the second arc ring 23 squeezes the first arc ring 14. The first arc ring 14 drives the first vertical plate 13 to rotate on the first fixed plate 11 through the hinge. The setting of the spring 172 avoids the first arc ring 14 from rigidly contacting the second arc ring 23. The first arc ring 14 contacts the second arc ring 23 to protect the electromagnetic sensor 16 and the magnet block 25. The electromagnetic sensor 16 detects the magnet block 25. Is it on the longitudinal horizontal line? If the magnet block 25 is on the longitudinal horizontal line, it means that there is no lateral deviation when the tipping machine platform is loaded with a heavy vehicle. On the contrary, the tipping machine platform has a lateral deviation. When the distance between the electromagnetic sensor 16 and the magnet block 25 is far, the first arc ring 14 and the second arc ring 23 are not in contact. The spring 172 drives the electromagnetic sensor 16 to slightly approach the magnet block 25 through the first vertical plate 13 to prevent the electromagnetic sensor 16 from not being able to sense the magnet block 25 when the gap is too large. The elastic component 17, the first arc ring 14 and the second arc ring 23 are set to prevent the electromagnetic sensor 16 from being scratched and no fault is detected.
