Abstract

Technical Field
[0001] The utility model relates to the technical field of rotary furnace equipment, in particular to a furnace thermal expansion tugboat device. Background Art
[0002] In industrial production, rotary furnace equipment is a common thermal equipment, which is widely used in various heat treatment, sintering, smelting and other processes. During the operation of the furnace body, due to the high temperature, thermal expansion often occurs, resulting in changes in the axial size of the furnace body. If this change is not effectively controlled and supported, it will have an adverse effect on the stability of the furnace body and the long-term operation of the equipment. Traditional furnace support devices usually adopt a fixed support structure, which cannot adapt to the size changes of the furnace body caused by thermal expansion. When the furnace body expands thermally, the fixed support structure cannot move accordingly, resulting in sliding friction between the furnace body and the support structure, which in turn causes wear on the contact surface. This wear not only affects the operating stability of the equipment, but also shortens the service life of the equipment and increases maintenance costs. Therefore, in order to solve the above problems, it is necessary to design a support device that can adapt to the thermal expansion of the furnace body, provide effective support when the size of the furnace body changes, avoid sliding friction and wear, and ensure the long-term stable operation of the equipment. Utility Model Content
[0003] The purpose of the utility model is to overcome the problems existing in the prior art and provide a furnace body thermal expansion tug wheel device. When the axial size of the furnace body changes, the sliding tug wheel will move with the movement of the roller, thereby ensuring that no sliding friction is generated between the sliding tug wheel and the furnace body roller during the operation of the equipment, no wear is caused on the contact surface, and long-term stable operation of the equipment is ensured.
[0004] The utility model is realized through the following technical scheme: a furnace thermal expansion tug device comprises a support seat, a rotating cylinder is rotatably arranged on the support seat, rollers are coaxially arranged on the outer side wall of the rotating cylinder, and tug assemblies are arranged on both sides of the support seat corresponding to the rollers of the rotating cylinder; the tug assembly comprises a tug shaft arranged along the axial direction of the rotating cylinder, a sliding tug is rotatably arranged on the tug shaft, the sliding tug can slide along the axial direction of the tug shaft, and the sliding tug and the roller cooperate with each other to perform rolling support.
[0005] In order to further optimize the utility model, the following technical solutions can be preferably used:
[0006] Preferably, a limiting boss is provided on the sliding tug wheel at one side close to the end of the rotating cylinder.
[0007] Preferably, a cylinder guard plate is provided on the rotating cylinder at a position corresponding to the roller, and the cylinder guard plate is welded to the rotating cylinder.
[0008] Preferably, the width of the cylinder guard plate is greater than the width of the roller, and support vertical plates are provided on the cylinder guard plate at positions corresponding to both sides of the roller, and the support vertical plates are used to provide radial supporting force to the roller.
[0009] Preferably, the support width of the sliding tugboat is greater than the width of the roller.
[0010] Preferably, the supporting upright plate and the cylinder guard plate, gear ring or roller are welded to each other.
[0011] Preferably, a supporting rib is further provided on the rotating cylinder at a position corresponding to between two adjacent supporting vertical plates, and the supporting rib welds the rotating cylinder, the cylinder guard plate, the gear ring or the supporting roller into one body.
[0012] Preferably, the supporting ribs and supporting vertical plates are arranged alternately on the rotating cylinder.
[0013] The beneficial effects of the utility model are mainly reflected in the following aspects:
[0014] The utility model of the furnace thermal expansion tug device effectively solves the sliding friction and wear problems generated by the furnace body during the thermal expansion process by adopting a rolling support method in which the sliding tug and the roller cooperate with each other. Specifically, when the furnace body undergoes thermal expansion and causes the axial size to change, the sliding tug can slide axially along the tug shaft as the roller moves, thereby maintaining rolling contact with the roller and avoiding the generation of sliding friction. This design not only reduces the wear of the contact surface and prolongs the service life of the equipment, but also improves the operating stability and reliability of the equipment. In addition, by adopting the design of the limiting boss, the position of the sliding tug during the movement can be limited to prevent it from excessive movement or falling off, further enhancing the stability and safety of the device. At the same time, the setting of the cylinder guard plate and the supporting vertical plate provides additional radial support force for the roller, enhances the supporting effect of the roller, and improves the bearing capacity of the entire device. In addition, the support width of the sliding tug is greater than the width of the roller, so that the sliding tug can better disperse the pressure during the rolling process and reduce the local wear of the roller. The welding connection between the support plate and the cylinder guard plate, gear ring or roller, as well as the setting of the support rib plate, further enhances the structural strength and stability of the entire device and improves the overall performance of the equipment. In summary, the furnace thermal expansion tugboat device of the utility model effectively solves the sliding friction and wear problems during the thermal expansion of the furnace through optimized design and structural improvement, improves the operating stability and service life of the equipment, reduces maintenance costs, and has significant beneficial effects.
