Description

Technical Field

[0001] The utility model relates to an adjustable crossbeam roller device, belonging to the technical field of steel metallurgical equipment. Background Art

[0002] At present, most of the domestic iron and steel metallurgical equipment contains a variety of process furnace equipment, including: quenching furnace, normalizing furnace, tempering furnace, etc., and these process furnaces have long been caused by the introduction of foreign matter on the surface of the steel plate and the increase of oxygen content in the furnace, resulting in nodules in the process furnace rollers, which shortens the replacement cycle of the furnace rollers to six months. The construction location in the furnace is small, the operation is difficult, and the continuous operation time is long, so the construction is difficult. The number of furnace rollers to be replaced each time the furnace is stopped is between 10 and 15, the diameter of the furnace roller is 380mm, the length is 6093mm, and the total weight is about 1800kg. In the process of replacing the furnace roller, due to the limited maintenance working environment conditions in the furnace, there is no point for hanging lifting equipment on it, so square steel is used on the radiation tube as the hanging point of the fall chain, and the furnace rollers are exported in batches by tilting the crane outside the furnace. This construction method requires a lot of personnel, high labor intensity, small and dense space, and low work efficiency, which poses a great safety hazard. Utility Model Content

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 , 2 As shown, an adjustable crossbeam roller device in this embodiment includes a main frame 1, and a support unit is symmetrically arranged at the bottom of the main frame 1. The support unit is mounted on two adjacent furnace rollers of the furnace roller to be replaced, so that the main frame 1 is supported above the furnace roller to be replaced. Two reinforcing rods 2 are arranged in the main frame 1, and the two reinforcing rods 2 are arranged at intervals along the length direction of the furnace roller to be replaced. Roller assemblies are respectively arranged under the reinforcing rods, and the roller assemblies are fixedly connected to the corresponding reinforcing rods 2 through corresponding adjustment mechanisms. The adjustment mechanism drives the roller assembly to move up and down, so that the roller assembly moves to the bottom of the furnace roller to be replaced, that is, the furnace roller to be replaced is supported on the roller assembly, which is convenient for workers to push the furnace roller to be replaced to move out of the furnace; or the roller assembly is kept away from the bottom of the furnace roller to be replaced, which is convenient for disassembling the device.

[0015] Each supporting unit comprises two wheel frames 6 arranged front and back, and a groove wheel 7 is arranged at the bottom of the wheel frame 6. The groove wheel matches the furnace roller, so that the groove wheel frame is arranged on the furnace roller.

[0016] The roller assembly includes two roller frames 4 arranged opposite to each other, and rollers 8 arranged obliquely are respectively provided on the roller frames 4. The two rollers 8 are symmetrically arranged, and the rollers 8 can rotate on the roller frames 4.

[0017] The adjusting mechanism comprises an adjusting frame 5, on which a roller frame 4 is fixed. Both ends of the adjusting frame 5 are provided with vertically arranged adjusting screws 3, on the top of which a reinforcing rod 2 is passed. The adjusting screw 3 is moved vertically to drive the adjusting frame 5 to move up and down, so that the roller assembly is close to or away from the furnace roller to be replaced. After the adjustment is in place, the adjusting nut is screwed into the end of the adjusting screw 3 to fix the adjusting screw 3 on the reinforcing rod 2.

[0018] The main frame 1 comprises two oppositely arranged cross beams 1.2, and the ends of the two cross beams 1.2 are fixedly connected by a connecting beam 1.1.

[0019] Two people are used to fix it. According to the distance between the furnace rollers, one construction worker places the main frame above the two adjacent furnace rollers so that the support unit is supported on the two adjacent furnace rollers. Another construction worker moves the adjustment frame to the bottom of the furnace roller to be replaced so that the roller assembly is located below the furnace roller to be replaced. The adjustment screw on the adjustment frame passes through the reinforcement plate. Then the construction worker above adjusts the height of the furnace roller to be replaced by adjusting the screw and adjusting the nut until the furnace roller to be replaced is stressed so that the two ends of the furnace roller to be replaced are parallel. A jack is used on the transmission side to push the furnace roller to be replaced out of the bearing step surface. Then the construction worker in the furnace freely pushes the furnace roller to be replaced. When half of the total length of the furnace roller to be replaced is pushed out of the furnace, the furnace roller to be replaced can be lifted out of the furnace by a crane and placed in a designated location. When installing a new furnace roller, first use a crane to transport the new furnace roller halfway into the furnace, then use a fall chain hung on the shaft head end on the transmission side to slowly pull it to the bearing step surface, and confirm and adjust the height of the device through the construction personnel on the transmission side, align the gap between the bearing step surface and the bearing inner ring, and use the fall chain to pull the furnace roller into position; after the passive end bearing end cover is installed, remove the device.

[0020] The present invention has a simple structure and is easy to operate, thereby improving the replacement efficiency and safety of the furnace rollers to be replaced, reducing personnel input, and reducing labor intensity.

[0021] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
