Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling, in particular to a cantilever roll assembly for a heating furnace. Background Art

[0002] In the metallurgical industry, a heating furnace is a device for heating materials or workpieces to the rolling or forging temperature. In an H-beam production line, a walking beam heating furnace is usually used to heat billets to 1280 - 1300 °C, and then through a cantilever roller table extending into the furnace at the tapping opening, the billets are transported out of the heating furnace for subsequent processing. As a bridge connecting the heating furnace and the subsequent processes, the design of the cantilever roller table fully considers the stability and durability under high-temperature environments. The rollers on the roller table are made of special high-temperature alloy materials and the surface is specially treated to improve wear resistance and anti-sticking steel performance, ensuring smooth operation under high-temperature and heavy-load conditions.

[0003] The traditional cantilever roll structure consists of a motor, a speed reducer, a transmission shaft, a base, a roller table, etc. Due to the high temperature in the furnace, the cantilever roll assembly often malfunctions and needs to be replaced as a whole. For example, the utility model patent with the publication number CN212692485U discloses a cantilever roller table for a steel heating furnace, which includes a base, a roller frame, roller wheels and a driving motor. A plurality of groups of roller frames are fixedly connected to the top of the base at equal intervals. Roller wheels are rotatably connected to the inner sides of the plurality of groups of roller frames. Driving motors driving the roller wheels are installed at the front ends of the plurality of groups of roller frames. Support frames are fixedly connected between the plurality of groups of roller frames on the top of the base, and a water storage tank is installed inside the base.

[0004] However, the above device still has certain problems. It is not convenient to quickly repair and replace the faulty cantilever roll structure. Manual replacement is time-consuming and laborious, with a large labor intensity. When performing manual replacement, the equipment has a long downtime, which greatly affects the production efficiency. Content of the Utility Model

[0005] The utility model aims at the problems in the prior art and provides a cantilever roll assembly for a heating furnace, which solves the problem that in the prior art, when a sudden failure occurs in the cantilever roll structure, it is necessary to shut down for a long time for manual replacement, resulting in a greater impact on production efficiency.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A cantilever roller assembly for a heating furnace, comprising a base, a moving mechanism is arranged on the base, the lower end of the moving mechanism is fixedly arranged on the base, the upper end of the moving mechanism can reciprocate in the length direction of the cantilever roller, a driving unit is arranged at the upper end of the moving mechanism, and one end of the driving unit is connected with a cantilever roller. By arranging the moving mechanism, when the working chamber of the cantilever roller is damaged, the driving unit and the cantilever roller can be moved. At this time, the cantilever roller is moved to a suitable position for the staff to facilitate maintenance or replacement, avoiding the time-consuming and laborious situation caused by manually moving the driving unit and the cantilever roller.

[0008] Preferably, the moving mechanism comprises two slide rails fixedly arranged on the base, a plurality of slide tables with the same quantity are evenly arranged on the two slide rails, a moving table is installed above the slide tables, the driving unit is arranged on the moving table, the moving mechanism further comprises a first motor fixedly arranged on the base, a lead screw is connected to the driving shaft of the first motor, a moving nut is sleeved on the lead screw, and the moving nut is fixedly connected with the moving table. By arranging the moving table and the first motor, the reciprocating movement of the moving table on the slide rails can be controlled by the forward and reverse rotation of the first motor, ensuring the accuracy of the cantilever roller during movement.

[0009] Preferably, the driving unit comprises a driving motor and a speed reducer, the driving motor is connected to the input shaft of the speed reducer, the output shaft of the speed reducer is connected with a transmission shaft, and the cantilever roller is fixedly connected with the transmission shaft.

[0010] Preferably, a rotating mechanism is arranged on the moving table, two driving units are arranged on the rotating mechanism, the two driving units are symmetrically arranged with respect to the rotating mechanism, and each driving unit is connected with a cantilever roller. By arranging the rotating mechanism and the two driving units, when the maintenance or replacement of the cantilever roller is required, the moving mechanism transports the moving table to the vicinity of the working platform, and then the rotating mechanism rotates to synchronously rotate the two groups of driving units and the corresponding cantilever rollers on the horizontal plane. When rotated 180°, the positions of the two corresponding cantilever rollers are replaced, and the undamaged cantilever roller continues to work. The disassembly-free replacement of the cantilever roller can be completed in a short time. After the replacement is completed, the driving mechanism sends the new cantilever roller to the working station, and the staff can perform maintenance or disassembly and replacement work on the just-damaged cantilever roller outside.

[0011] Preferably, the rotating mechanism comprises a circular rotating table, the rotating table is rotatably arranged on the moving table around an axis, the rotating mechanism further comprises a second motor fixedly arranged on the moving table, the output shaft of the second motor is connected with a driving gear, and a driven gear is arranged on the circumferential surface of the rotating table, and the driving gear is meshed with the driven gear.

[0012] Preferably, a plurality of pulleys are evenly arranged on the lower end surface of the rotating table, and the pulleys are placed on the upper end surface of the moving table. By arranging the pulleys, the friction between the rotating table and the moving table can be reduced.

[0013] As can be seen from the above technical solutions, the advantages of the present utility model are as follows: through the provided moving mechanism, when the cantilever roller working chamber is damaged, the driving unit and the cantilever roller can be moved. At this time, the cantilever roller is moved to a suitable position for easy maintenance or replacement by the staff, avoiding the time-consuming and laborious situation caused by manually moving the driving unit and the cantilever roller. Through the provided moving table and the first motor, the reciprocating movement of the moving table on the slide rail can be controlled by the forward and reverse rotation of the first motor, ensuring the accuracy of the cantilever roller during movement. Through the provided rotating mechanism and two driving units, when the cantilever roller needs to be repaired or replaced, the moving mechanism transports the moving table to near the working platform, and then the rotating mechanism rotates to synchronously rotate the two groups of driving units and the corresponding cantilever rollers on the horizontal plane. When rotated 180°, the two corresponding cantilever rollers complete the position replacement, and the undamaged cantilever roller continues to work. The cantilever roller can be replaced without disassembly in a short time. After the replacement is completed, the driving mechanism sends the new cantilever roller to the working station, and the staff can perform maintenance or disassembly and replacement work on the just-damaged cantilever roller outside. Through the provided pulleys, the friction between the rotating table and the moving table can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS
