Abstract
Description
Technical Field
[0001] The invention relates to a high-speed trolley for metallurgical equipment, which is mainly used in steel enterprises and belongs to the technical field of metallurgical machinery. Background Art
[0002] When steel companies produce steel, they need to grind the surface of the steel billets rolled out of the rolling mill or continuously cast to meet the requirements of the subsequent processes, so as to remove surface defects and improve the yield rate of the subsequent processes. In the production process, they often pursue higher grinding capacity and lower maintenance costs.
[0003] At present, the running speed of domestic grinding trolleys is between 10-60m / min. In the past, the billet was located on one side of the grinding trolley, and the impact on the trolley was relatively large during the billet turning and clamping process, and the stability was poor, so the increase in running speed has a great impact on the stability and economy of the equipment.
[0004] The invention patent with application number 201420746390.2 discloses a billet grinding trolley, including a trolley body, a plurality of wheel axles are arranged at the bottom of the trolley body, a reduction motor is arranged at the upper end of the wheel axle, a wheel is arranged on the wheel axle, guide wheels are arranged on both sides of the wheel, and a turning mechanism and a clamping mechanism are arranged on the trolley body. The above patent replaces the original hydraulic winch mode with a reduction motor drive, which reduces the rigidity and strength requirements of the trolley. The reduction motor is installed on the wheel axle to directly drive the wheel to rotate, which improves the running speed and production capacity of the trolley; the trolley has a clamping and turning mechanism, and a notch is opened on the turning plate. When turning the material, one corner of the billet rests on the notch, which minimizes the impact and improves the running stability of the equipment. However, the above turning mechanism includes a connecting shaft, and a plurality of front and rear turning arms are arranged on the connecting shaft. In the process of turning the billet, the plurality of turning arms will inevitably be subjected to uneven force, thereby causing the turning arms to sink unevenly, affecting the stability of the trolley operation. Summary of the invention
[0005] The technical problem to be solved by the present invention is to provide a high-speed trolley for metallurgical equipment in response to the above-mentioned prior art, which lowers the position of the synchronous shaft, and the hydraulic cylinder drives the connecting rod to drive the synchronous shaft to move. The flip arm and the synchronous shaft are connected by a two-way adjustment screw rod, and the length of the screw rod can be fine-tuned, thereby reducing the error between the flip arms, ensuring the consistency of the flip arms, and improving the stability of the trolley operation.
[0006] The technical solution adopted by the present invention to solve the above problems is as follows: A high-speed trolley for metallurgical equipment, which includes a frame. A plurality of tipping frames are sequentially arranged on the frame from front to back. A tipping arm is hingedly arranged on the tipping frame. A synchronous shaft is arranged along the front-rear direction below the tipping arm. A plurality of first connecting rods are arranged on the synchronous shaft, and the positions of the plurality of first connecting rods respectively correspond to the positions of the plurality of tipping arms. The first connecting rod and the middle part of the tipping arm are connected by a bidirectional adjustment screw rod.
[0007] Optionally, a plurality of oil cylinder seats are arranged on one side of the synchronous shaft. An oil cylinder is hingedly arranged on the oil cylinder seat. A second connecting rod is arranged on the synchronous shaft at the corresponding position of the oil cylinder. The piston rod end of the oil cylinder is hingedly connected to the second connecting rod.
[0008] Optionally, the tipping arm is hingedly arranged at the top of the tipping frame.
[0009] Optionally, the end of the tipping arm is hingedly arranged on the tipping frame through a pin shaft, and the tipping arm is arranged at the front and rear ends of the pin shaft.
[0010] Optionally, both ends of the bidirectional adjustment screw rod are respectively connected to the tipping arm and the first connecting rod through connecting ear seats.
[0011] Optionally, two groups of left and right traveling wheel boxes are arranged at the bottom of the frame.
[0012] Optionally, two left and right guide rails are arranged below the frame, and two groups of left and right traveling wheel boxes are arranged on the two left and right guide rails.
[0013] Compared with the prior art, the advantages of the present invention are as follows:
[0014] 1. In the present invention, the position of the synchronous shaft is lowered, the hydraulic cylinder drives the connecting rod to drive the synchronous shaft to act, and the tipping arm and the synchronous shaft are connected by a bidirectional adjustment screw rod, and its length can be finely adjusted, so as to reduce the error between the tipping arms, ensure the consistency of the tipping arms, and improve the running stability of the trolley;
[0015] 2. In the present invention, the synchronous shaft is arranged below and the billet is arranged in the middle. On the one hand, it can reduce the overall height of the trolley and lower the overall center of gravity of the trolley. On the other hand, the center of gravity of the trolley is set between the left and right wheel groups, improving the running stability of the equipment and creating conditions for the high-speed running of the trolley (the fastest 80 m / min);
[0016] 3. The present invention uses an integrated wheel box to replace the original wheel group and positioning components. Its assembly is simple, and it is not easy to generate cumulative machining errors, effectively improving the running accuracy of the trolley; at the same time, it has good sealing performance and can effectively protect the traveling wheels from the influence of external machinery, harsh environment, etc. Description of the Drawings
