Description

Technical Field

[0001] The invention belongs to the field of cold billet feeding, and in particular relates to a cold billet feeding stand device. Background Art

[0002] In actual use, the existing cold billet loading stand device needs suitable billets to be transported to the heating furnace on the roller, but unsuitable billets or problems with the heating furnace require these billets to be unloaded or transported away first. At the same time, since the equipment layout of the steel plant is very compact, it is obviously unreasonable to add another stand device for unloading in the limited cavity. Therefore, a cold billet loading stand device with dual functions of loading and unloading is urgently needed. Summary of the invention

[0003] In view of this, the present invention aims to propose a cold billet loading stand device, which is improved from the original one-way billet loading function to a two-way function of loading and unloading billets, and has both loading and unloading dual functions.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A cold billet loading platform device is arranged between two cross beams, and comprises a lever, a movable stopper, and a driving mechanism for driving the movable stopper to alternately rise and fall;

[0006] The lever extends upwards and is higher than the steel passing surface of the cold billet loading platform. The lever is rotatably mounted on the movable crossbeam through bolts, and the lever rotates around the bolts.

[0007] There are two movable blocks, which are respectively arranged on both sides of the lever, a support plate is arranged under the movable block, and a connecting rod is also arranged under the support plate. One end of the connecting rod is hinged to the output shaft of the driving mechanism, and the other end is hinged to the support plate. A cavity for accommodating the support plate is provided in the movable crossbeam, and the driving mechanism drives the support plate to move up and down alternately in the cavity by driving the connecting rod, thereby driving the movable block arranged on the support plate to move up and down.

[0008] Furthermore, there is a gap between the guide block and the shifting rod;

[0009] A guide block is also provided at the lower part of the lever, and the guide block is assembled on the movable crossbeam through bolts. The guide block is used to limit the rotation range of the lever to ensure that the lever rotates in a small range.

[0010] Furthermore, a cavity for accommodating the movable stopper is formed between the guide block and the movable crossbeam, and the formed cavity is used to ensure that the support plate and the movable stopper can move up and down.

[0011] Further, the driving mechanism comprises a synchronous shaft arranged below the movable crossbeam, and the movable stopper is hinged to the synchronous shaft through a connecting rod;

[0012] A hydraulic cylinder is also provided at one end of the synchronous shaft, and the hydraulic cylinder drives the synchronous shaft to move forward and backward in the horizontal direction.

[0013] Furthermore, there are multiple synchronous shafts, and the multiple synchronous shafts are connected by pull rods.

[0014] Furthermore, the upper end of the connecting rod is hinged to the movable stopper, and the lower end is hinged to the synchronization shaft.

[0015] Furthermore, a bearing seat is provided below the movable crossbeam, and the synchronization shaft is installed on the movable crossbeam through the bearing seat.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] like Figures 1 to 4 As shown, a cold billet loading platform device is arranged between two beams, including a lever 8, a movable stopper 1 and a driving mechanism for driving the movable stopper 1 to alternately rise and fall;

[0030] The lever 8 extends upwardly above the steel passing surface of the cold billet loading platform, and the lever 8 is rotatably installed with the movable crossbeam 10 through the bolt 7, and the lever 8 rotates around the bolt 7; the lever 8 is upwardly higher than the steel passing surface to limit the steel billet 11 passing the steel surface, and the lever 8 can rotate to achieve a buffering effect when the lever 8 contacts the steel billet 11, thereby reducing damage to the lever 8 and the steel billet 11 due to inertia during hard contact.

[0031] There are two movable stops 1, which are respectively arranged on both sides of the lever 8. A support plate is arranged below the movable stop 1, and a connecting rod 2 is also arranged below the support plate. One end of the connecting rod 2 is hinged to the output shaft of the driving mechanism, and the other end is hinged to the support plate. A cavity 12 for accommodating the support plate is provided in the movable crossbeam 10. The driving mechanism drives the support plate to move up and down alternately in the cavity 12 by driving the connecting rod 2, thereby driving the movable stopper 1 arranged on the support plate to move up and down; the support plate is driven to move up and down by the output end of the hydraulic cylinder 6 through the connecting rod 2 hinged at the bottom, and the output shaft moves horizontally, and the two support plates arranged at both ends of the lever 8 are driven to move up and down by the connecting rod 2 hinged at the bottom of the support plate, thereby driving the movable stopper 1 arranged on the support plate to move up and down.

[0032] There is a gap between the guide block 9 and the lever 8 ; the gap is used to ensure that the lever 8 can swing slightly left and right relative to the fulcrum bolt 7 , so as to achieve a buffering effect during the contact between the lever 8 and the steel billet 11 .

[0033] A guide block 9 is also provided at the lower part of the lever 8. The guide block 9 is assembled on the movable cross beam 10 by means of bolts 7. The guide block 9 is used to limit the rotation range of the lever 8 to ensure that the lever 8 rotates slightly. The guide block 9 is set below the lever 8 with a gap therebetween. The gap ensures that the lever 8 can swing slightly left and right. The rotation range of the lever 8 is limited by the guide block 9.

[0034] A cavity 12 for accommodating the movable stopper 1 is formed between the guide block 9 and the movable cross beam 10. The formed cavity 12 is used to ensure that the support plate and the movable stopper 1 can move up and down.

[0035] The driving mechanism comprises a synchronous shaft 3 arranged below the movable cross beam 10, and the movable stopper 1 is hinged to the synchronous shaft 3 via a connecting rod 2; the synchronous shaft 3 is used to drive the movable stopper 1 to move up and down alternately.

[0036] A hydraulic cylinder 6 is also provided at one end of the synchronous shaft 3, and the hydraulic cylinder 6 drives the synchronous shaft 3 to move forward and backward in the horizontal direction.

[0037] There are multiple synchronous shafts 3 , and the multiple synchronous shafts 3 are connected by pull rods 5 .

[0038] The upper end of the connecting rod 2 is hinged to the movable stopper 1 , and the lower end is hinged to the synchronous shaft 3 .

[0039] A bearing seat 4 is provided below the movable crossbeam 10 , and the synchronous shaft 3 is installed on the movable crossbeam 10 through the bearing seat 4 .

[0040] like Figure 1As shown, the two movable blocks 1 are respectively arranged on both sides of the guide block 9, and the guide block 9 is assembled on the movable crossbeam 10 through shafts and bolts. Due to the action of the guide block 9 and the steel plate on the movable crossbeam 10, the movable block 1 can only make up and down reciprocating movements along a straight line through the push-pull action of the connecting rod 2, and the two connecting rods 2 acting on the two movable blocks 1 are respectively assembled on the same synchronous shaft 3, and the synchronous shaft 3 is installed on the movable crossbeam 10 through the bearing seat 4. In this way, the entire existing feeding function is realized when the movable crossbeam 10 moves, that is, when the movable crossbeam 10 moves, the lower synchronous shaft 3 and the connecting rod 2 pull the movable block 1 to make it in a working state where the right side is high and the left side is low, so that the lever 8 can push the steel billet 11 to move to one side of the roller. At the same time, the synchronous shaft of each section is connected by the connecting rod 5 until it is finally connected to the hydraulic cylinder 6 to achieve the synchronization of the action of all movable blocks 1 to complete the transportation of multiple blanks 11. At this time, the hydraulic cylinder 6 is in a retracted state, that is, at this time, a pulling force is generated on the connecting rod 2 and the synchronous shaft 3.

[0041] like Figure 2 As shown, the hydraulic cylinder 6 is in an extended state, that is, under the pushing action of the hydraulic cylinder 6, the synchronous shaft 3 and the connecting rod 2 push the movable stopper 1 to be higher on the left and lower on the right, thereby realizing the work of the shifting rod 8 to transport the steel billet 11 away from the roller table.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
