Description

Technical Field

[0001] This utility model relates to the field of traction wheel production technology, and in particular to a heating furnace for traction wheel production. Background Technology

[0002] The traction sheave is the device that transmits traction power in an elevator. The traction sheave can be divided into two parts: the sheave cylinder and the sheave rim. The sheave cylinder is the middle part, and the sheave rim is fitted onto the sheave cylinder. The annular surface of the sheave rim is cut with rim-shaped rope grooves. The traction sheave has characteristics such as high hardness, high wear resistance, and impact resistance. The traction sheave is mostly made of ductile iron. After the components of the traction sheave are manufactured, they need to be heated and shaped in a heating furnace to increase the overall hardness of the traction sheave.

This paper proposes a heating furnace for traction wheel production to solve the above problems. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4A heating furnace for traction wheel production includes a furnace body 1 and several traction wheel bodies 2. Conveyors 3 are installed on the left and right sides of the furnace body 1 near the bottom. The conveyors 3 transport the traction wheel bodies 2 placed in a loading trough 7 into the furnace body 1. Several heater bodies 4 are fixedly installed at the upper end of the furnace body 1. The output ends of each heater body 4 are connected to a first heat-conducting pipe 5. The lower ends of each first heat-conducting pipe 5 vertically penetrate the top surface of the furnace body 1. The first heat-conducting pipes 5 are located within the furnace body 1. Each end of the furnace body 1 is equipped with a heating head 6. The inner walls of the left and right sides of the furnace body 1, located above the conveyor 3, are equipped with shifting adjustment mechanisms. Each shifting adjustment mechanism includes a fixed seat 8, which is fixedly connected to the inner walls of the left and right sides of the furnace body 1. Both fixed seats 8 are located above the conveyor 3. Each fixed seat 8 has a cavity 9. A servo motor 10 is fixedly installed on the front side wall of each fixed seat 8. A lead screw 11 is horizontally rotatably inserted through the inner walls of the front and rear sides of each cavity 9. Activating the servo motor 10 on the two fixed seats 8 drives the lead screw 11. 1. Rotation: Two lead screws 11 are threaded with displacement blocks 12. Each of the two cavities 9 has a strip-shaped opening 13 on its opposite inner wall. The two displacement blocks 12 pass through the strip-shaped openings 13 on both sides. A strip-shaped connecting block 14 is fixedly connected to the opposite side wall of the two displacement blocks 12 outside the strip-shaped openings 13. The strip-shaped connecting block 14 is associated with several heating heads 6. Limiting rods 15 are fixedly connected to the front and rear inner walls of the cavity 9 near the top and bottom. Limiting blocks 16 are fixedly connected to the upper and lower ends of the displacement blocks 12. The limiting rod 15 is horizontally inserted through the two limiting blocks 16, so that the rotation of the screw 11 drives the threaded displacement block 12 to move horizontally along the strip opening 13 under the limiting action of the limiting rod 15 and the limiting block 16. The two displacement blocks 12, together with the strip connecting block 14 and several annular connecting blocks 18, drive the heating head 6 to move horizontally along the direction of the material loading trough 7 within the extension range of the heat-conducting bend 19. Thus, the heating heads 6 heat the several traction wheel bodies 2 arranged on the conveyor 3, thereby improving the heating efficiency.

[0023] The shift adjustment mechanism is associated with several heating heads 6. Each heating head 6 has a second heat-conducting pipe 17 connected to its upper end. Each second heat-conducting pipe 17 is fitted with an annular connecting block 18, which is fixedly connected to a strip connecting block 14. Each second heat-conducting pipe 17 has a heat-conducting bend 19 connected to its upper end. The lower ends of several first heat-conducting pipes 5 are connected to the heat-conducting bends 19. The heater body 4, in conjunction with the first heat-conducting pipes 5, second heat-conducting pipes 17, heat-conducting bends 19, and heating heads 6, heats several traction wheel bodies 2 arranged in multiple lines within the material loading trough 7. The upper end of the conveyor 3 has several material loading troughs 7, and several traction wheel bodies 2 are respectively inserted into these troughs. Each material loading trough 7 has a side wall near its lower end... The device has heat dissipation channels 20 that are connected on both sides. Several heat dissipation fins 21 are fixedly installed on the top surface of each heat dissipation channel 20. Two partitions 22 are fixedly connected to the bottom of each heat dissipation channel 20. The two partitions 22 divide the material loading tank 7 into equal parts. Several traction wheel bodies 2 are respectively inserted between two adjacent partitions 22 in the material loading tank 7. The lower ends of the several traction wheel bodies 2 are in contact with the heat dissipation fins 21. The heat dissipation fins 21 and the partitions 22 are both made of aluminum-copper alloy. The contact between the several traction wheel bodies 2 in the material loading tank 7 and the heat dissipation fins 21 allows the heat dissipation channels 20, together with the aluminum-copper alloy heat dissipation fins 21 and the partitions 22, to quickly conduct heat to the traction wheel bodies 2 in the material loading tank 7. With the help of an external fan, the heat dissipation effect of the traction wheel bodies 2 is improved.

[0024] In use, several traction wheel bodies 2 are inserted into several material loading troughs 7, such that the traction wheel bodies 2 are inserted between two adjacent partition plates 22 and abut against several heat dissipation fins 21 on the bottom of the material loading troughs 7. The material loading troughs 7 are placed on the conveyor 3 and transported to the heating furnace body 1. The heater body 4 is started, and the first heat conduction pipe 5, the second heat conduction pipe 17, the heat conduction bend 19 and the heating head 6 are used to heat the several traction wheel bodies 2 arranged in multiple lines in the material loading troughs 7. The servo motors 10 on the two fixed seats 8 are started to drive the lead screw 11 to rotate. The rotation of the lead screw 11 drives the threaded displacement block 12 to move between the limiting rod 15 and the limiting block 1. Under the limiting action of 6, it moves horizontally along the strip opening 13, and the two shifting blocks 12, together with the strip connecting block 14 and several ring connecting blocks 18, drive the heating head 6 to move horizontally along the direction of the loading trough 7 within the extension range of the heat-conducting bend 19. This allows several heating heads 6 to heat several traction wheel bodies 2 arranged on the conveyor 3, thereby improving the heating efficiency. The several traction wheel bodies 2 in the loading trough 7 come into contact with the heat sink 21, so that the heat dissipation channel 20, together with the heat sink 21 and the partition 22 made of aluminum-copper alloy, can quickly conduct heat to the traction wheel bodies 2 in the loading trough 7. With the help of the external fan, the heat dissipation effect of the traction wheel bodies 2 is improved.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
