Description

Technical Field

[0001] This utility model relates to the field of trolley track crossing technology, and in particular to a track changing auxiliary mechanism for a calcium carbide furnace trolley. Background Technology

[0002] The three furnace openings of a large calcium carbide furnace are evenly distributed at 120° angles. The furnace outlet track inevitably needs to be designed in an arc shape. For example, in CN107906968B, a circular track for calcium carbide outlets surrounds the three furnace openings with two circular tracks. When one of the furnace openings is running (the three openings do not run simultaneously), the calcium carbide-carrying trolley moves along the circular track for initial cooling. However, because the two circular tracks are not interconnected, a single circular track becomes idle, resulting in a shortage of cooling points. To solve this problem, the plant design incorporates intersecting and connecting circular and straight tracks. However, the calcium carbide furnace trolley cannot smoothly change tracks at the intersection of the circular and straight tracks. Therefore, a track-changing auxiliary mechanism is designed. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary mechanism for changing tracks of a calcium carbide furnace trolley, so as to solve the problems existing in the prior art.

[0004] This utility model is implemented by the following technical solution: a track-changing auxiliary mechanism for a calcium carbide furnace trolley, which includes a left-right symmetrical groove at the intersection of a circular track and a straight track, and two slide rails arranged perpendicular to the straight track in each groove, with both ends of each slide rail extending through the circular track and the straight track at the intersection and fixedly connected to the ground. A movable plate that can slide along the slide rails is provided on the two slide rails in each groove, and a driving assembly is provided outside each groove. Each driving assembly is connected to the end of the movable plate that protrudes out of the corresponding groove. An arc-shaped monorail is provided on one side of the moving plate. When the moving plate slides to contact the outer monorail of the straight track, the arc-shaped monorail aligns with the outer monorail of the adjacent circular track. A straight monorail is provided on the other side of the moving plate. When the moving plate slides to contact the inner monorail of the circular track, the straight monorail aligns with the inner monorail of the adjacent straight track.

[0005] Preferably, each of the drive components includes a telescopic cylinder, a first connecting rod, and a second connecting rod; a support platform is fixed on the ground on one side of the intersection, the telescopic cylinder is provided on the support platform, the cylinder body of the telescopic cylinder is fixed on the support platform, the rod of the telescopic cylinder is hinged to the top end of the first connecting rod, the bottom end of the first connecting rod is hinged to the ground, and the middle part of the first connecting rod is hinged to the end of the corresponding movable plate that extends out of the groove.

[0006] Preferably, two guide strips are fixed on the lower surface of each of the movable plates, the two guide strips are placed between the corresponding two slide rails, and the two guide strips and the two slide rails form a sliding contact in a one-to-one correspondence.

[0007] Advantages of this utility model: This utility model is equipped with two driving components, controlling the extension and retraction of the telescopic cylinders of the two driving components, so that the two moving plates slide along the slide rail direction in the corresponding grooves respectively. The specific process is as follows: when the telescopic cylinder of the driving component retracts, the corresponding moving plate contacts the outer single rail of the straight track, and the arc-shaped single rail aligns with the outer single rail of the circular track; when the telescopic cylinder of the driving component extends, the corresponding moving plate contacts the inner single rail of the circular track, and the straight single rail aligns with the inner single rail of the straight track; by flexibly controlling the position of the two moving plates in the corresponding grooves, the calcium carbide furnace trolley can smoothly change tracks, realizing that the calcium carbide furnace trolley always travels on the circular track / always travels on the straight track / changes from the straight track to the circular track / changes from the circular track to the straight track.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] like Figures 1-6 As shown, a track-changing auxiliary mechanism for a calcium carbide furnace trolley includes a left-right symmetrical groove 3 at the intersection of a circular track 1 and a straight track 2. Two slide rails 4 are arranged perpendicular to the straight track 2 in each groove 3. Both ends of each slide rail 4 extend through the circular track 1 and the straight track 2 at the intersection and are fixedly connected to the ground by bolts. A movable plate 5, which can slide along the slide rails 4, is provided on the two slide rails 4 within each groove 3. Two guide strips 6 are fixed on the lower surface of each movable plate 5. The two guide strips 6 are placed between the corresponding two slide rails 4, and the two guide strips 6 and the two slide rails 4 form a one-to-one sliding contact. The guide strips 6 serve to guide and limit. A drive assembly 7 is provided near the two grooves 3 on the outer side of the intersection. Each drive assembly 7 includes a telescopic cylinder 7.1, a first connecting rod 7.2, and a second connecting rod 7.3. The drive assembly 7 is fixed on the ground on one side of the intersection. A support platform 10 is provided, on which a telescopic cylinder 7.1 is provided. The cylinder body of the telescopic cylinder 7.1 is fixed on the support platform 10. The rod of the telescopic cylinder 7.1 is hinged to the top end of the first connecting rod 7.2. The bottom end of the first connecting rod 7.2 is hinged to the ground. The middle part of the first connecting rod 7.2 is hinged to the end of the movable plate 5 that extends out of the corresponding groove 3. The telescopic cylinder 7.1 extends and retracts, causing the first connecting rod 7.2 to rotate around the bottom hinge point. The rotation of the first connecting rod 7.2 causes the second connecting rod 7.3 to move, thereby controlling the movable plate 5 to move along the slide rail 4 within the groove 3. An arc-shaped monorail 8 is provided on one side of each movable plate 5 for docking with the outer monorail of the circular track 1, facilitating smooth track changes for the calcium carbide furnace trolley 11. When the movable plate 5 slides to contact the outer monorail of the straight track 2, the arc-shaped monorail 8 aligns with the outer monorail of the adjacent circular track 1. A straight monorail 9 is provided on the other side of each movable plate 5 for docking with the inner monorail of the straight track 2, facilitating smooth track changes for the calcium carbide furnace trolley 11. When the movable plate 5 slides to contact the inner monorail of the circular track 1, the straight monorail 9 aligns with the inner monorail of the adjacent straight track 2.

[0022] like Figure 7 As shown, when the telescopic cylinder 7.1 retracts, the moving plate 5 contacts the outer monorail of the straight track 2, and the arc-shaped monorail 8 aligns with the outer monorail of the circular track 1; as Figure 8 As shown, when the telescopic cylinder 7.1 extends, the moving plate 5 contacts the inner monorail of the circular track 1, and the straight monorail 9 aligns with the inner monorail of the straight track 2.

[0023] Working principle: When the calcium carbide furnace trolley 11 continues to travel on the circular track 1 after passing the intersection, as... Figure 1 As shown, the telescopic cylinders 7.1 of the two drive components 7 on the left and right are in the retracted state, and both moving plates 5 are in contact with the outer single rail of the straight track 2. The arc-shaped single rails 8 on the two moving plates 5 are respectively aligned with the outer single rail of the adjacent circular track 1. When the calcium carbide furnace trolley 11 enters the left movable plate 5 from the circular track 1, the outer wheel 11.1 of the calcium carbide furnace trolley 11 first rolls over the arc-shaped monorail 8 on the left movable plate 5. At the same time, the inner wheel 11.2 of the calcium carbide furnace trolley 11 rolls over the inner monorail of the circular track 1 (the wheel flange of the inner wheel 11.2 is located in the gap, and the wheel surface of the inner wheel 11.2 is located on the outer monorail of the straight track 2). Then, when the calcium carbide furnace trolley 11 continues to travel and enters the right movable plate 5, the outer wheel 11.1 of the calcium carbide furnace trolley 11 rolls over the arc-shaped monorail 8 on the right movable plate 5 again. At the same time, the inner wheel 11.2 of the calcium carbide furnace trolley 11 rolls over the inner monorail of the circular track 1. The above can ensure that the calcium carbide furnace trolley 11 always travels on the circular track 1.

[0024] When the calcium carbide furnace trolley 11 continues to travel on the straight track 2 after passing the intersection, as Figure 9 As shown, the telescopic cylinders 7.1 of the two drive components 7 on the left and right are in the extended state, and the two moving plates 5 are in contact with the inner single rail of the circular track 1. The straight single rails 9 on the two moving plates 5 are respectively aligned with the inner single rail of the adjacent straight track 2. When the calcium carbide furnace trolley 11 enters the left moving plate 5 from the straight track 2, the inner wheel 11.2 of the calcium carbide furnace trolley 11 first rolls over the straight monorail 9 on the left moving plate 5. At the same time, the outer wheel 11.1 of the calcium carbide furnace trolley 11 rolls over the outer monorail of the straight track 2 (the wheel flange of the outer wheel 11.1 is located in the gap, and the wheel surface of the outer wheel 11.1 is located on the outer monorail of the straight track 2). Then, when the calcium carbide furnace trolley 11 continues to travel into the right moving plate 5, the inner wheel 11.2 of the calcium carbide furnace trolley 11 rolls over the straight monorail 9 on the right moving plate 5 again. At the same time, the outer wheel 11.1 of the calcium carbide furnace trolley 11 rolls over the outer monorail of the straight track 2 (the wheel flange of the outer wheel 11.1 is located in the gap, and the wheel surface of the outer wheel 11.1 is located on the outer monorail of the straight track 2). The above ensures that the calcium carbide furnace trolley 11 always travels on the straight track 2.

[0025] When the calcium carbide furnace trolley 11 changes track from the straight track 2 to the circular track 1 at the intersection, as Figure 10 As shown, the telescopic cylinder 7.1 of the left drive assembly 7 is in the extended state, the left moving plate 5 is in contact with the inner monorail of the circular track 1, and the straight monorail 9 on the left moving plate 5 is aligned with the inner monorail of the adjacent straight track 2; the telescopic cylinder 7.1 of the right drive assembly 7 is in the retracted state, the right moving plate 5 is in contact with the outer monorail of the straight track 2, and the arc-shaped monorail 8 on the right moving plate 5 is aligned with the outer monorail of the adjacent circular track 1. When the calcium carbide furnace trolley 11 enters the left moving plate 5 from the straight track 2, the inner wheel 11.2 of the calcium carbide furnace trolley 11 first rolls over the straight monorail 9 on the left moving plate 5. At the same time, the outer wheel 11.1 of the calcium carbide furnace trolley 11 rolls over the outer monorail of the straight track 2 (the wheel flange of the outer wheel 11.1 is located in the gap, and the wheel surface of the outer wheel 11.1 is located on the outer monorail of the straight track 2). When the calcium carbide furnace trolley 11 continues to travel into the right moving plate 5, the outer wheel 11.1 of the calcium carbide furnace trolley 11 rolls over the arc-shaped monorail 8 on the right moving plate 5. At the same time, the inner wheel 11.2 of the calcium carbide furnace trolley 11 rolls over the inner monorail of the circular track 1. The above enables the calcium carbide furnace trolley 11 to change track from the straight track 2 to the circular track 1 at the intersection.

[0026] When the calcium carbide furnace trolley 11 changes track from the circular track 1 to the straight track 2 at the intersection, as Figure 11 As shown, the telescopic cylinder 7.1 of the left drive assembly 7 is in the retracted state, the left moving plate 5 is in contact with the outer monorail of the straight track 2, and the arc-shaped monorail 8 on the left moving plate 5 is aligned with the outer monorail of the adjacent annular track 1; the telescopic cylinder 7.1 of the right drive assembly 7 is in the extended state, the right moving plate 5 is in contact with the inner monorail of the annular track 1, and the straight monorail 9 on the right moving plate 5 is aligned with the inner monorail of the adjacent straight track 2. When the calcium carbide furnace trolley 11 enters the left movable plate 5 from the circular track 1, the outer wheel 11.1 of the calcium carbide furnace trolley 11 first rolls over the arc-shaped monorail 8 on the left movable plate 5. At the same time, the inner wheel 11.2 of the calcium carbide furnace trolley 11 rolls over the inner monorail of the circular track 1 (the wheel flange of the inner wheel 11.2 is located in the gap, and the wheel surface of the inner wheel 11.2 is located on the outer monorail of the straight track 2). Then, the calcium carbide furnace trolley 11 continues to travel into the right side. When the carbide furnace trolley 11 is on the moving plate 5, the inner wheel 11.2 of the carbide furnace trolley 11 rolls over the straight monorail 9 on the right moving plate 5. At the same time, the outer wheel 11.1 of the carbide furnace trolley 11 rolls over the outer monorail of the straight track 2 (the wheel flange of the outer wheel 11.1 is located in the gap, and the wheel surface of the outer wheel 11.1 is located on the outer monorail of the straight track 2). In this way, the carbide furnace trolley 11 can change tracks from the circular track 1 to the straight track 2 at the intersection.
