Description

Technical Field

[0001] The utility model relates to the field of iron and steel production, in particular to an anti-arching and shoulder-riding device for a sintering machine trolley. Background Art

[0002] A sintering machine mainly consists of upper and lower guide rails, front and rear star wheels, curved rails, a transmission mechanism, and trolleys arranged on the upper and lower guide rails. The trolley is the main equipment for sintered ore production. The rotation of the trolley at the rear star wheel is provided with thrust by the star wheel teeth. This thrust is composed of a horizontal component force that pushes the trolley to move on the return rail. Each trolley squeezes against each other and generates an upward frictional component force. The greater the thrust, the greater the frictional component force. When the moment generated by this frictional component force is greater than the moment of the trolley's own weight, the rear part of the trolley will be lifted upward. As the star wheel continues to rotate, the front end face of the subsequent trolley contacts the rear end face of the previous trolley, forming a shoulder-riding state. The height difference between the front and rear trolleys is generally 20 - 50 mm. When the shoulder-riding trolley moves towards the front star wheel, the extrusion moment gradually becomes smaller. When it is less than the moment of the trolley's own gravity, the arced trolley will instantaneously fall, generating a huge impact, damaging the trolley bearings, causing equipment accidents, unevenly wearing the end faces of the trolleys, increasing the air leakage rate, reducing the production efficiency, and at the same time causing damage and deformation to the trolley body. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an anti-arching and shoulder-riding device for a sintering machine trolley, which utilizes a seesaw structure to achieve automatic top pressure and reset during the forward movement of the trolley, eliminating the shoulder-riding of the trolley.

[0004] An anti-arching and shoulder-riding device for a sintering machine trolley includes: a limiting mechanism. The limiting mechanism is installed above the lower guide rail. The limiting mechanism includes a fixed base and a balance beam. The balance beam is hinged to the fixed base to form a seesaw structure. Two spaced inclined pressure blocks are provided at the bottom of the balance beam. The hinge point between the balance beam and the fixed base is located between the two inclined pressure blocks. The distance between the two inclined pressure blocks is equivalent to the distance between the front wheel and the rear wheel of the trolley.

[0005] In one embodiment, a raised hinge seat is provided on the fixed base, and the balance beam is hinged to the hinge seat.

[0006] In one embodiment, an elastic member is provided between the balance beam and the fixed base. One end of the elastic member is connected to the balance beam, and the other end is connected to the fixed base.

[0007] In one embodiment, the anti-arching and shoulder-riding device for a sintering machine trolley includes two such elastic members, and the two elastic members are respectively located on both sides of the hinge seat.

[0008] In one of the embodiments, a connecting rod is provided between the balance beam and the inclined pressure block, and the connecting rod connects the inclined pressure block and the balance beam.

[0009] In one embodiment, the fixed base is located below the balance beam, and the fixed base is located between the two connecting rods.

[0010] In one of the embodiments, the inclined pressure block is provided with a slope surface in the oncoming direction of the trolley.

[0011] In one of the embodiments, a gap is provided between the bottom surface of the inclined pressure block and the bottom of the trolley during normal operation.

[0012] Compared with the prior art, the advantages of the anti-sintering machine trolley arching shoulder device of the utility model are:

[0013] The balance beam is used to form a seesaw effect, so that when the front wheel of the shouldered trolley lifts up an inclined pressure block, due to the seesaw effect of the balance beam, the other inclined pressure block can press down the rear wheel of the shouldered trolley, so that the trolley can release the shoulder and return to a normal state. The device can avoid the trolley from arching and shouldering, eliminate the hidden danger of the trolley falling, thereby increasing the service life of the trolley and ensuring the working efficiency of the trolley.

[0024] As Figure 1 shown, it is the structure where the trolley has a shoulder overlap, and the trolleys are inclined and stacked.

[0025] As Figures 2 to 4As shown in the figure, the anti-arching and shoulder-riding device for the sintering machine trolley in this embodiment includes a limiting mechanism 7. The limiting mechanism 7 is installed above the lower guide rail 3. The limiting mechanism 7 includes a fixed base 8 and a balance beam 9. The balance beam 9 is hinged to the fixed base 8 to form a seesaw structure. There are two spaced inclined pressing blocks 10 at the bottom of the balance beam 9. The hinge point between the balance beam 9 and the fixed base 8 is located between the two inclined pressing blocks 10. The distance between the two inclined pressing blocks 10 is equivalent to the distance between the front wheel 5 and the rear wheel 6 of the trolley 4. The inclined pressing blocks 10 are used to press down the shoulder-riding trolley 4. The trolley 4 is inverted when on the lower guide rail 3, that is, the bottom of the trolley 4 faces up and the top faces down. When the trolley 4 on the lower guide rail 3 shoulders, the bottom of the trolley 4 tilts up and touches the inclined pressing blocks 10. When the trolley 4 moves forward, the bottom of the trolley 4 touches the two inclined pressing blocks 10 simultaneously. As the trolley 4 continues to move forward, the front inclined pressing block 10 is lifted, and the rear inclined pressing block 10 is pressed down by the seesaw action of the balance beam 9, finally completing the pressing and leveling of the trolley 4 and releasing the shoulder-riding of the trolley 4.

[0026] There is a raised hinge seat 12 on the fixed base 8, and the balance beam 9 is hinged to the hinge seat 12.

[0027] There is an elastic member 13 between the balance beam 9 and the fixed base 8. One end of the elastic member 13 is connected to the balance beam 9 and the other end is connected to the fixed base 8. The elastic member 13 is used to provide auxiliary force for the balance beam 9 to return to the balanced state, making the operation of the trolley 4 smoother. In this embodiment, the elastic member 13 is a rubber block, which has a large load-bearing capacity and good resilience. Preferably, this embodiment includes two elastic members 13, and the two elastic members 13 are respectively located on both sides of the hinge seat 12. Lifting the balance beam 9 away from the fixed base 8 through the hinge seat 12 facilitates the installation of the fixed base 8 on the equipment and also provides space for the installation of the elastic member 13.

[0028] There is a connecting rod 11 between the balance beam 9 and the inclined pressing block 10. The connecting rod 11 connects the inclined pressing block 10 and the balance beam 9. The fixed base 8 is located below the balance beam 9 and between the two connecting rods 11. By setting the connecting rod 11, the inclined pressing block 10 is far away from the fixed base 8, facilitating the installation of the fixed base 8 above the lower guide rail 3. The fixed base 8, the hinge seat 12, and the elastic member 13 are accommodated between the two connecting rods 11, with a compact structure, forming a module, having a small volume, and being conducive to upgrading and transformation on existing equipment.

[0029] The inclined pressing block 10 is provided with a slope surface 14 in the oncoming vehicle direction of the trolley 4. The slope surface 14 faces the oncoming vehicle direction, which can guide the movement of the wheels of the trolley 4 and reduce the impact.

[0030] When the trolley 4 is running normally and no shoulder-riding occurs, there is a gap between the bottom surface of the inclined pressing block 10 and the bottom of the normally running trolley 4. When the normally running trolley 4 passes through, neither the front wheel 5 nor the rear wheel 6 will touch the limiting mechanism 7, which has no impact on the normal running of the trolley.

[0031] The present utility model has been described in conjunction with the preferred embodiments, but the present utility model is not limited to the disclosed embodiments above, and should cover various modifications and equivalent combinations made according to the essence of the present utility model.
