Description

Technical Field

[0001] This invention relates to the field of sintering machine equipment technology, and in particular to an adjustable stacking elimination device for the return track trolley of a sintering machine. Background Technology

[0002] During the return trip of the sintering machine, the sintering machine trolley experiences a shoulder-stacking problem due to friction and thermal deformation of the tail wheel swing frame. After the shoulder-stacking phenomenon occurs, the trolley's running state on the track is as follows: Figure 1 As shown, the rear end of the trolley arches (the rear wheels are raised), and its front end overlaps with the rear end of the trolley in front. The friction between them is very high, making it difficult for the trolley's own weight to press down the arched rear end. This overlapping arching causes wear on the bottom corners of the trolleys. When the arched trolley reaches the head, due to its own weight and the movement of the head star wheel, the trolley will suddenly fall, causing a "crash" phenomenon, damaging the wheel axles and bearings, and resulting in equipment accidents and shutdowns. It also causes wear on the end faces of the trolleys and side panels, increasing air leakage, reducing the service life of the rails and trolleys, and increasing spare parts consumption.

[0003] Currently, most shoulder-overlap elimination devices are installed on the return track, but this method has the following disadvantages: 1. This installation method results in very high resistance for the trolley to eliminate shoulder overlap; 2. The height of the shoulder-overlap elimination device cannot be adjusted as needed, and for trolleys with a large amount of shoulder overlap, there is a possibility that the shoulder overlap phenomenon cannot be completely eliminated; 3. It will increase harmful forces that are detrimental to the operation of the equipment; 4. It cannot be replaced when the pressure rail is worn. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an adjustable stacking elimination device for the return track trolley of a sintering machine.

[0005] To achieve the above objectives, the present invention is implemented according to the following technical solution: An adjustable stacking elimination device for a sintering machine return track trolley is installed between truncated sintering machine return tracks. It includes a track seat and an adjustable track cap. The two ends of the track seat are fixedly connected to the ends of the truncated sintering machine return tracks. The track seat is a section of the sintering machine return track, and the upper surfaces of the track seat and the sintering machine return track are on the same plane. The adjustable track cap is located in the middle of the track seat and includes a toothed inclined track cap for an incline section, a toothed flat track cap for a horizontal section, and a toothed inclined track cap for a downhill section. Each of these three sections includes a rail web and a rail head with the same structure and dimensions as the sintering machine return track, fixed to the top of the rail web. A section of the rail head is cut off along the length direction from the middle of the top of the track seat to form a section. The rail waist support plate, the toothed inclined rail cap of the climbing section, the toothed flat rail cap of the horizontal section, and the toothed inclined rail cap of the downhill section all have grooves for embedding the rail waist support plate on the rail seat. The rear end of the rail waist of the toothed inclined rail cap of the climbing section is rotatably connected to the support plate through a rotating shaft, and the front end has a first arc-shaped tooth surface. The front end of the rail waist of the toothed inclined rail cap of the downhill section is rotatably connected to the support plate through a rotating shaft, and the rear end has a second arc-shaped tooth surface. Both ends of the toothed flat rail cap of the horizontal section have linear tooth surfaces. The linear tooth surface at the rear end of the toothed flat rail cap of the horizontal section meshes with the first arc-shaped tooth surface, and the linear tooth surface at the front end of the toothed flat rail cap of the horizontal section meshes with the second arc-shaped tooth surface. The outer walls on both sides of the rail waist of the toothed flat rail cap of the horizontal section are symmetrically provided with driving mechanisms for driving the toothed flat rail cap of the horizontal section up and down.

[0006] Furthermore, the drive mechanism includes nuts symmetrically fixed on the outer walls of both sides of the rail web of the horizontal toothed flat rail cap, with screws internally threaded onto the nuts. A screw support seat is fixed on the bottom of the rail of the horizontal toothed flat rail cap. The lower end of the screw passes through the screw support seat and the bottom of the rail and is connected to a first gear. The first gear meshes with a second gear, and the second gear is fixed to the end of the output shaft of the reduction motor.

[0007] Furthermore, the horizontal section toothed flat track cap has a first notch at the middle of both ends of the rail head, and the track seat above the column plate has a second notch at the middle of the inner end of the rail head. The climbing section toothed inclined track cap and the descending section toothed inclined track cap have protruding blocks at the middle of both ends of the rail head that cooperate with the first notch and the second notch, respectively.

[0008] Compared with the prior art, the adjustable stacking elimination device for the sintering machine return track trolley of the present invention is installed below the trolley during operation. First, the height and angle of the adjustable track cap are adjusted according to the amount of stacking on the trolley. When the trolley at the front of the stack passes the adjustable track cap, the front of the trolley first passes through the climbing section, causing the front of the trolley to arch. At this time, the rear end of the trolley and the front end of the trolley behind it change from surface contact to point contact, thereby greatly reducing the friction between adjacent trolleys. Then, under the action of the trolley's own weight, the rear end of the trolley falls onto the track. After the trolley continues to pass through the horizontal section and the downhill section, the contact between adjacent trolleys is eliminated, thereby completely eliminating the stacking phenomenon. Moreover, the entire stacking elimination device for the sintering machine return track trolley is installed on the sintering machine return track with bolts and nuts, which makes it easy to replace when wear occurs.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0023] like Figure 1 As shown, this embodiment specifically discloses an adjustable stacking elimination device for a sintering machine return track trolley, installed between the cut-off sintering machine return tracks. It includes a track seat 1 and an adjustable track cap. The two ends of the track seat 1 are fixedly connected to the ends of the cut-off sintering machine return tracks. The track seat 1 is a section of the sintering machine return track, and the upper surfaces of the track seat 1 and the sintering machine return track are on the same plane. The adjustable track cap is located in the middle of the track seat 1 and includes a climbing section toothed inclined track cap 2, a horizontal section toothed flat track cap 3, and a descending section toothed inclined track cap 4. Each of these sections includes a rail web and a rail head with the same structure and size as the sintering machine return track, fixed to the top of the rail web. A section of the rail head is cut off along the length direction from the middle of the top of the track seat 1 to form a rail web column plate 10. 1. The rail webs of the climbing section toothed inclined rail cap 2, the horizontal section toothed flat rail cap 3, and the downhill section toothed inclined rail cap 4 are all provided with grooves 11 for embedding into the rail web column plate 101 on the rail seat 1. The rear end of the rail web of the climbing section toothed inclined rail cap 2 is rotatably connected to the column plate 101 via a rotating shaft, and the front end is provided with a first arc-shaped tooth surface 21. The front end of the rail web of the downhill section toothed inclined rail cap 4 is rotatably connected to the column plate 101 via a rotating shaft, and the rear end is provided with a second arc-shaped tooth surface 41. Both ends of the horizontal section toothed flat rail cap 3 are provided with linear tooth surfaces 31. The linear tooth surface 31 at the rear end of the horizontal section toothed flat rail cap 3 meshes with the first arc-shaped tooth surface 21, and the linear tooth surface 31 at the front end of the horizontal section toothed flat rail cap 3 meshes with the second arc-shaped tooth surface 41. The outer walls on both sides of the rail web of the horizontal section toothed flat rail cap 3 are symmetrically provided with driving mechanisms for driving the horizontal section toothed flat rail cap to move up and down.

[0024] Specifically, such as Figure 2 As shown, the driving mechanism includes nuts 5 symmetrically fixed on the outer walls of both sides of the rail web of the horizontal section toothed flat rail cap 3. A screw 7 is internally threaded onto the nuts 5. A screw support seat 6 is fixed on the bottom of the rail of the horizontal section toothed flat rail cap 3. The lower end of the screw 7 passes through the screw support seat 6 and the bottom of the rail and is connected to a first gear 8. The first gear 8 meshes with a second gear 9. The second gear 9 is fixed to the end of the output shaft of the reduction motor 10.

[0025] Furthermore, the horizontal section toothed flat track cap 3 has a first notch 32 at the middle of both ends of the rail head, and the inner end of the rail head of the track seat above the column plate 101 has a second notch 102. The climbing section toothed inclined track cap 2 and the descending section toothed inclined track cap 4 have protruding blocks 12 at the middle of both ends of the rail head that cooperate with the first notch 32 and the second notch 102, respectively. That is, the protruding block 12 at one end of the climbing section toothed inclined track cap 2 cooperates with the second notch 102 at one end of the column plate 101. The protruding block 12 at the other end of the inclined track cap 2 engages with the first notch at one end of the horizontal section toothed flat track cap 3. The first notch 32 at the other end of the horizontal section toothed flat track cap 3 engages with the protruding block 12 at one end of the downhill section toothed inclined track cap 4. The protruding block 12 at the other end of the downhill section toothed inclined track cap 4 engages with the second notch 102 at the other end of the column plate 101. With the above engagement, the toothed inclined track cap 2, the horizontal section toothed flat track cap 3, and the downhill section toothed inclined track cap 4 are prevented from getting stuck during their movement.

[0026] The working principle of this invention is as follows: 1. First, adjust the height and angle of the adjustable track cap according to the amount of shoulder overlap on the trolley. The specific adjustment process is as follows: When the trolley overlap is small, the two reduction motors 10 are started simultaneously to reverse. At this time, the second gear 10 drives the first gear 8 and the screw 7 to rotate clockwise simultaneously. The nut 5 will then move downwards along the screw 7 in a straight line, thus lowering the height of the horizontal section toothed flat track cap 3. Under the action of the linear tooth surface 31 of the horizontal section toothed flat track cap 3, the climbing section toothed inclined track cap 2 and the downhill section toothed inclined track cap 4 will rotate downwards simultaneously. At this time, the climbing section toothed inclined track cap 2 and the horizontal section toothed flat track cap 4... The low camber formed by the track cap 3 and the toothed inclined track cap 4 on the downhill section can be used to eliminate the shoulder overlap when the amount of trolley overlap is small. The front end of trolley 13 first passes through the climbing section, causing the front end of the trolley to camber. At this time, the rear end of trolley 13 and the front end of the trolley behind it change from surface contact to point contact, which greatly reduces the friction between adjacent trolleys. Then, under the action of the self-weight of trolley 13, the rear end of the trolley falls onto the track. After trolley 13 continues to pass through the horizontal section and the downhill section, the contact between adjacent trolleys is eliminated, thus completely eliminating the trolley shoulder overlap phenomenon.

[0027] When the trolley has a large amount of shoulder overlap, the two reduction motors 10 are started simultaneously to rotate forward. At this time, the second gear 10 drives the first gear 8 and the screw 7 to rotate counterclockwise. The nut 5 will move upward in a straight line along the screw 7, thereby increasing the height of the horizontal section toothed flat track cap 3. Under the action of the linear tooth surface 31 of the horizontal section toothed flat track cap 3, the climbing section toothed inclined track cap 2 and the downhill section toothed inclined track cap 4 will rotate upward simultaneously. At this time, the camber formed by the climbing section toothed inclined track cap 2, the horizontal section toothed flat track cap 3 and the downhill section toothed inclined track cap 4 is large, which can be used to eliminate the shoulder overlap when the trolley has a large amount of shoulder overlap.

[0028] The technical solutions of the present invention are not limited to the specific embodiments described above. Any technical modifications made in accordance with the technical solutions of the present invention fall within the protection scope of the present invention.
