Description

Technical Field

[0001] This utility model relates to the technical field of track-type feeding trolleys, and more particularly to track-type feeding trolleys used in steel metallurgy. Background Technology

[0002] Metallurgical rail-mounted feeding trolleys are automated logistics equipment specifically designed for material handling in the metallurgical industry. They are primarily used for material handling during metal smelting processes, including iron ore, slag, limestone, and coke. These materials need to be fed into the smelting furnace in specific proportions during the smelting process. However, existing metallurgical rail-mounted feeding trolleys require a motor to tilt the trolley after it reaches the top of the smelting furnace. Using a motor for tilting can damage the motor over time, increasing production costs. Manual tilting, on the other hand, increases the risk of injury to workers due to the high furnace temperature. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rail-type feeding trolley for steel metallurgy, which solves the technical problem of requiring a motor to trigger the turning of the mine car, thereby reducing production costs.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rail-type feeding trolley for iron and steel metallurgy, including a mine car body as a supporting foundation, a side-tipping reset assembly for unloading is installed inside the mine car body, and an anti-tipping reset assembly for triggering the tipping unloading step is installed on the side-tipping reset assembly.

[0005] The anti-flipping assembly includes a transmission seat that is connected through to one end of the mine car body. An anti-rod is rotatably connected to one side of the transmission seat. An active toothed opening is provided at one end of the anti-rod located inside the transmission seat. An anti-reset spring is connected between the anti-rod and the outside of the mine car body. A driven gear is rotatably connected to the side of the transmission seat away from the anti-rod. A snap-fit ​​bent rod is fixedly connected to the middle of the top of the driven gear.

[0006] Preferably, the side-tipping reset assembly includes a tilting chamber disposed inside the body of the mine car, a guide bucket fixedly connected to one side of the tilting chamber, a tilting shaft fixedly connected to both ends of the tilting chamber and rotatably connected to the mine car body, a plurality of rebound springs equidistantly connected between the mine car body and the tilting chamber, and a fixed return rod fixedly connected to the end of the mine car body near the driven gear.

[0007] Preferably, the end of the fixed return bend is bent toward the mine car body, and the fixed return bend is engaged with the snap-on bend.

[0008] Preferably, pulleys are fixedly connected to the four corners of the bottom of the mine car body, and a track is laid at the bottom of the pulleys. Abutment frames are fixedly connected to both sides of the track by brackets.

[0009] Preferably, the mine car body and the contact frame are provided with a mine car limiting component for fixing and releasing the mine car body;

[0010] The mine car limiting assembly includes a bow frame fixedly connected to one side of the mine car body. A curved connecting rod is slidably connected in the middle of the bow frame. A limiting plate is fixedly connected to one end of the curved connecting rod outside the bow frame. A contact rod return spring is connected to the inner part of the bow frame outside the curved connecting rod. A limiting rod is fixedly connected to the end of the curved connecting rod. A one-way tilting frame is fixedly connected in the middle of the contact frame through a bracket. An arc-shaped locking plate is rotatably connected to the inner side of the one-way tilting frame.

[0011] Preferably, one end of the curved connecting rod extends through to the inside of the mine car body and fits against the outside of the tipping compartment, and the limiting rod is fitted with the arc-shaped card plate.

[0012] By employing the above technical solution, this utility model provides a rail-type feeding trolley for iron and steel metallurgy, which has at least the following beneficial effects:

[0013] 1. Due to the setting of the anti-overturning component, this utility model can use the reaction force generated by the impact stop when the mine car body is running to drive the driven gear and the buckle bent rod fixedly connected to its top to overturn, thereby losing the limit on the overturning bin. At that time, the overturning bin will overturn and unload the material because it loses the limit, so that no manual intervention or motor intervention is required, which can reduce production costs and avoid personnel injury.

[0014] 2. Due to the setting of the mine car limiting component, this utility model can self-lock after the mine car body moves to the designated position, thereby fixing the position of the mine car body. After the material is unloaded from the tipping bin, the rebound force when the tipping bin is reset will drive the bending connecting rod to move, thereby causing the limiting rod to lose its engagement with the arc-shaped card plate. This allows the mine car body to continue to move, thereby preventing personnel from getting close and making the material unloading process safer. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Existing metallurgical track-type feeding trolleys require a motor to tilt the ore car after reaching the top of the smelting furnace. However, this motor-driven tilting will eventually damage the motor, increasing production costs. Manual tilting, on the other hand, increases the risk of worker injury due to the high furnace temperature. Please refer to [reference needed]. Figures 1-9 This embodiment provides a track-type feeding trolley for steel metallurgy, solving the technical problem that the tilting of the mine car requires motor triggering. The device includes a mine car body 1 as a supporting foundation, a tilting reset assembly 2 for unloading installed inside the mine car body 1, and a trigger tilting assembly 3 for triggering the tilting and unloading step installed on the tilting reset assembly 2. Material is unloaded through the tilting reset assembly 2, and the tilting is triggered by the trigger tilting assembly 3.

[0033] In the traditional use of mining cars, unloading is usually done by motor or manually. However, this unloading method increases production costs and the probability of personnel injury. To avoid this situation, the anti-tipping component 3 is proposed. The anti-flip assembly 3 includes a transmission seat 31 that is connected through to one end of the mine car body 1. An anti-rod 32 is rotatably connected to one side of the transmission seat 31. The inclined anti-rod 32 is easy to rotate when it comes into contact with an external object. An active toothed mouth 33 is provided at one end of the anti-rod 32 located inside the transmission seat 31. When the anti-rod 32 is resisted, it will drive the active toothed mouth 33 to rotate. An anti-reset spring 34 is connected between the anti-rod 32 and the outside of the mine car body 1. The anti-reset spring 34 can reset the anti-rod 32 after it flips. A driven gear 35 is rotatably connected to the side of the transmission seat 31 away from the anti-rod 32. The rotating active toothed mouth 33 will drive the driven gear 35 to rotate. A snap-fit ​​bent rod 36 is fixedly connected to the middle of the top of the driven gear 35. The driven gear 35 can drive the snap-fit ​​bent rod 36 to flip by rotating.

[0034] To facilitate unloading from the mine car, the side-tipping reset assembly 2 includes a tilting chamber 21 located inside the mine car body 1. The tilting chamber 21 stores materials. A guide bucket 22 is fixedly connected to one side of the tilting chamber 21. The guide bucket 22 increases the gravity on one side of the tilting chamber 21, thereby shifting its center of gravity and making it easier to tilt. At the same time, the guide bucket 22 also makes unloading smoother. Both ends of the tilting chamber 21 are fixedly connected to a tilting shaft 23 that is rotatably connected to the mine car body 1. Several spring springs 24 are equidistantly connected between the mine car body 1 and the tilting chamber 21. In order to enable the tilting chamber 21 to reset after unloading, a fixed return bending rod 25 is fixedly connected to the end of the mine car body 1 near the driven gear 35. The end of the fixed return bending rod 25 bends towards the mine car body 1, and the fixed return bending rod 25 engages with the snap-fit ​​bending rod 36. The engagement of the fixed return bending rod 25 and the snap-fit ​​bending rod 36 provides a limiting position.

[0035] Example 2

[0036] Based on Example 1, which solved the technical problem of requiring a motor to trigger the mine car's tilting, Example 1 still suffers from unstable positioning when the mine car stops. Combined with... Figures 1-9 As shown, the specific implementation process is as follows: Pulleys 6 are fixedly connected to the four corners of the bottom of the mine car body 1. A track 7 is laid at the bottom of the pulleys 6, and contact frames 4 are fixedly connected to both sides of the track 7 via brackets. A motor and traction rope are installed at a distance, allowing the mine car body 1 to slide on the track 7. By tilting the track 7, the mine car body 1 can slide down automatically when transporting materials towards the furnace. After unloading, it can be pulled back by a motor at a distance for reloading.

[0037] After the mine car reaches the furnace feed inlet, a mine car limiting component 5 is installed on the mine car body 1 and the contact frame 4 to limit and fix the position of the mine car. The mine car limiting component 5 includes a bow frame 51 fixedly connected to one side of the mine car body 1. A curved connecting rod 52 is slidably connected in the middle of the bow frame 51. One end of the curved connecting rod 52 extends through to the inside of the mine car body 1 and fits against the outside of the tilting chamber 21. In order to receive the rebound force when the tilting chamber 21 resets, the rebound force will drive the curved connecting rod 52 to move. A limiting plate 53 is fixedly connected to the outer end of the curved connecting rod 52 outside the bow frame 51. In order to prevent the curved connecting rod 52 from sliding out of the bow frame 51, a contact rod return spring 54 is connected to the inner part of the bow frame 51 outside the curved connecting rod 52. The rod 52 can return to its original position after being abutted. The end of the bent connecting rod 52 is fixedly connected to a limiting rod 55. The middle of the abutting frame 4 is fixedly connected to a one-way flipping frame 56 through a bracket. The inner side of the one-way flipping frame 56 is rotatably connected to an arc-shaped clamping plate 57. The limiting rod 55 is engaged with the arc-shaped clamping plate 57. When the abutting rod 32 abuts against the abutting frame 4, it will turn back. At that time, the limiting rod 55 will contact the arc-shaped clamping plate 57 until it is engaged with the arc-shaped clamping plate 57. Because the arc-shaped clamping plate 57 is limited by the one-way flipping frame 56, the limiting rod 55 cannot disengage from the arc-shaped clamping plate 57 until the bent connecting rod 52 is displaced. At that time, the bent connecting rod 52 will drive the limiting rod 55 to move and disengage from the arc-shaped clamping plate 57.
