Description

Technical Field

[0001] The utility model relates to the technical field of a continuous casting machine billet transfer vehicle, in particular to a billet transfer vehicle with an anti-tooth jump function. Background Art

[0002] With the rapid development of continuous casting technology, high-speed casting technology has been widely used, and the function of the billet transfer car as a key link of the continuous casting machine has become more prominent. The continuous casting billet transfer car is one of the key equipment for transporting continuous casting billets. In the actual production process, the gear of the continuous casting billet transfer car is disengaged from the rack, causing the gear and rack to be misaligned, resulting in the gears at both ends of the billet transfer car moving out of sync, commonly known as "tooth jumping". The main reason for "tooth jumping" is that the billet transfer car pushes the continuous casting billet due to bending or excessive resistance of the billet, bridging of the steel fork, etc., which leads to the misalignment of the gear and rack of the billet transfer car. The billet transfer car tooth jumping failure can easily lead to the interruption of continuous casting production organization, and at the same time, safety accidents are very likely to occur in the process of dealing with the billet transfer car tooth jumping. Summary of the invention

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a billet transfer vehicle with anti-tooth jumping.

[0004] The specific scheme of the utility model is: a blank transfer cart with anti-tooth jumping, comprising two support frames, on which the blank transfer carts are installed, a rack is installed on the top of each support frame along the length direction, and gears are installed at both ends of the blank transfer cart corresponding to the racks on both sides, and the gears are meshed with the corresponding racks. A segment limiting section is installed on each side opposite to the two support frames, and a group of guide wheels are installed at each end of the blank transfer cart, and the guide wheels are arranged directly below the limiting section, and the distance between the top of the guide wheel and the limiting section is less than the tooth height of the rack.

[0005] Furthermore, the number of the guide wheels in the group is two, and the two guide wheels are respectively arranged on both sides of the blank transfer vehicle.

[0006] Furthermore, each guide wheel is mounted on a fixed shaft, a bearing is arranged between the guide wheel and the fixed shaft, and mounting frames are arranged on both sides of the body of the billet transfer vehicle corresponding to the fixed shaft, and the mounting frames are connected to the fixed shaft.

[0007] Furthermore, the distance between the apex of the guide wheel and the limiting section is 1-3 mm.

[0008] Furthermore, the length of the limiting section is smaller than the length of the rack, and the area between the two support frames where the limiting section is not provided is used for the inspection and replacement of the billet transfer vehicle.

[0009] The utility model has the following beneficial effects: it ensures the meshing degree of the gear and the rack during the movement of the billet transfer car, thereby effectively preventing the gear and the rack of the billet transfer car from being separated and misaligned; it ensures the needs of high-efficiency continuous casting and continuous casting production, and reduces the maintenance frequency of the billet transfer car.

[0014] See also Figure 1-3 , This embodiment is a kind of anti-jumping tooth transfer vehicle 4, including two support frames 1 with a length of 20 meters, and a transfer vehicle 4 is installed on the two support frames 1 together, and a rack 2 is installed on the top of each support frame 1 along the length direction, and gears 3 are installed at both ends of the transfer vehicle 4 corresponding to the racks 2 on both sides, and the gears 3 are meshed with the corresponding racks 2, and the gears 3 are connected to the driving mechanism, and the driving mechanism drives the gears 3 to roll along the racks 2, thereby driving the transfer vehicle 4 to move along the support frame 1 as a whole, and a segment limit segment 8 is installed on each side opposite to the two support frames 1, and the length of the limit segment 8 is 18 meters, which is arranged from one end of the support frame 1, and the limit segment 8 is formed by a bracket with an L-shaped cross section fixedly connected to the support frame 1, and a plurality of reinforcing rib plates are arranged between the L-shaped bracket and the support frame 1, and the short side of the L-shape is the limit segment 8, and a group of guide wheels 7 are installed at each end of the transfer vehicle 4, and the guide wheels 7 are arranged directly below the limit segment 8, and the distance between the vertex of the guide wheel 7 and the limit segment 8 is 1-3mm. Further, the number of the set of guide wheels 7 is two, and the two guide wheels 7 are symmetrically arranged on both sides of the billet transfer vehicle 4. Further, each guide wheel 7 is sleeved on a fixed shaft, and a bearing is installed between the guide wheel 7 and the fixed shaft. Mounting frames 6 are installed on both sides of the body of the billet transfer vehicle 4 corresponding to the fixed shaft, and the mounting frames 6 are connected to the fixed shaft.

[0015] When the blank transfer cart 4 moves, if there is a tendency of "tooth jumping" due to various external reasons, since guide wheels 7 are provided at both ends of the body of the blank transfer cart 4, and the distance between the guide wheel 7 and the limiting section 8 is less than the tooth height, the blank transfer cart 4 as a whole is limited in the vertical direction, so that the blank transfer cart 4 and the gear 3 can only move upward a maximum distance of 1-3mm, so that the gear 3 cannot be separated from the rack 2, which can greatly reduce the number of "tooth jumping" phenomena, and even avoid the "tooth jumping" phenomenon.

[0016] Furthermore, the length of the limit section 8 is smaller than the length of the rack 2, and the area between the two support frames 1 where the limit section 8 is not provided is used for the inspection and replacement of the billet transfer trolley 4; when the billet transfer trolley 4 needs to be inspected or replaced, the billet transfer trolley 4 can be moved to the area where the limit section 8 is not provided. In this area, the billet transfer trolley 4 is not limited in the vertical direction, and the billet transfer trolley 4 can be inspected or replaced by a crane.
