Description

Technical Field

[0001] The utility model relates to the technical field of quenching furnaces, in particular to a forklift quenching furnace. Background Art

[0002] Forklift quenching furnace is a kind of equipment used for quenching metal materials, which is widely used in various industrial fields. Compared with ordinary quenching furnaces, forklift quenching furnaces are equipped with transport forklifts to facilitate the transport of quenching material carts in and out of the furnace body. Since the existing forklifts are single-sided cantilever beam structures, the length of the material fork cannot be too long because it will bend, which also leads to the length of the quenching furnace cannot be made longer due to the length limit of the material fork, which leads to the space of the quenching furnace being limited and cannot be enlarged. Since the existing forklift quenching furnace usually transports metal materials in and out by quenching material carts, the traditional cast-type support columns are prone to cracks due to pressure under high temperature, resulting in poor load-bearing capacity and high frequency of subsequent maintenance.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figures 1 to 6The utility model provides a technical solution: a forklift quenching furnace, including a concrete floor 1, a bottom furnace lining 2 is laid above the concrete floor 1, the bottom furnace lining 2 is made of (QZ)-1.0 lightweight clay bricks and insulation bricks, and has the effect of heat insulation, a heating device is installed around the furnace cover 5, a furnace body 3 is installed above the bottom furnace lining 2, a support column 4 is installed on the upper surface of the bottom furnace lining 2 located in the furnace body 3, a furnace cover 5 is hoisted on the top of the furnace body 3, a quenching trolley 6 covered by the furnace cover 5 is placed above the support column 4, the support column 4 is composed of a bottom high-aluminum brick and a top heat-resistant cast steel part and is reliably fixed, and its structure matches the loading and transferring quenching trolley 6 to ensure that its surface strength is sufficient and can withstand weight impact A liftable furnace door 7 is installed at the front and rear of the furnace body 3, a track 8 is installed above the concrete floor 1 near the furnace body 3, a three-dimensional quenching forklift 9 is arranged above the track 8, the three-dimensional quenching forklift 9 includes a walking trolley 901, a lifting mechanism 902 and a material fork 903, a telescopic support mechanism 904 is installed below the material fork 903, a lifting plate 905 is arranged between the top of the telescopic support mechanism 904 and the top wall of the material fork 903, a wedge block 906 is installed on the lifting plate 905 near the front of the telescopic support mechanism 904, a rack 907 is installed on the lifting plate 905 near the bottom of the lifting mechanism 902, and a rotating shaft is installed on the side of the material fork 903 near the rack 907 to insert into the material fork 903 The reduction motor 908 of the reduction motor 908 is provided on the rotating shaft thereof, and a gear 909 meshing with the rack 907 is installed. The number of support columns 4 is several and evenly distributed in a rectangular array, and horizontal and vertical grooves are formed between the support columns 4. The number of material forks 903 is the same as the number of transverse grooves, the width of the material fork 903 is smaller than the width of the transverse groove, and the length of the material fork 903 is larger than the length of the transverse groove. The telescopic support mechanism 904 includes an outer rectangular tube 9041, and an inner rectangular tube 9042 that can slide up and down is arranged inside the outer rectangular tube 9041, an upper guide wheel 9043 is installed on the upper end of the inner rectangular tube 9042, and a lower wheel 9044 is installed on the lower end of the inner rectangular tube 9042. The reduction motor 908 The cooperation of the rack 907 and the gear 909 can drive the lifting and pulling plate 905 to slide forward and backward. When the lifting and pulling plate 905 slides forward and backward, the upper guide wheel 9043 can be pushed downward by the wedge block 906 to change the height of the telescopic support mechanism 904. When the telescopic support mechanism 904 is in the shortest state, the upper surface of the material fork 903 is lower than the support column 4. When the telescopic support mechanism 904 is in the highest state, the upper surface of the material fork 903 is higher than the support column 4. There are several telescopic support mechanisms 904 with the same structural dimensions. The telescopic support mechanism 904 synchronously lifts or lowers the material fork 903 under the drive of the reduction motor 908, and the internal power of the lifting mechanism 902 is only responsible for straightening the material fork 903.

[0024] When in use, first place the quenching trolley 6 to the middle position above the material fork 903, then place the material to be quenched inside the quenching trolley 6, then open the furnace doors 7 at both ends of the furnace body 3, then lift the furnace cover 5 upwards, then clean the upper surface of the bottom furnace lining 2 to prevent debris from blocking the material fork 903 from being fed in, then reducer motor 908 drives gear 909 to rotate, and when gear 909 rotates, it drives the lifting plate 905 to move backwards through rack 907, and in this process, the wedge block 906 is inserted above the upper guide wheel 9043, and then the telescopic support mechanism 904 is The inner rectangular tube 9042 of the furnace body 3 is pushed down, and in this process, the height of the telescopic support mechanism 904 becomes longer and then the material fork 903 is raised too high, so that the lower surface of the quenching trolley 6 is higher than the support column 4. The walking trolley 901 further works to drive the three-dimensional quenching forklift 9 to travel on the track 8, that is, the walking trolley 901 carries the material fork 903 and sends the quenching trolley 6 to the inside of the furnace body 3. When the quenching trolley 6 is transported to the middle position just above the support column 4, the walking trolley 901 stops working, and the reduction motor 908 is further reversed to lift the lifting plate 905 through the cooperation of the gear 909 and the rack 907. The quenching material cart 6 is pushed forward. During this process, the wedge block 906 exits the range of the upper guide wheel 9043, causing the inner rectangular tube 9042 to lose support and move upward, thereby shortening the telescopic support mechanism 904 and causing the material fork 903 to drop. As a result, the quenching material cart 6 also drops synchronously and finally falls on the support column 4. Since the support column 4 is composed of a high-aluminum brick at the bottom and a heat-resistant cast steel part at the top and is reliably fixed, its structure matches the loading and transferring quenching material cart 6, ensuring that its surface strength is sufficient to withstand weight impact, and thus it is not easy to crack and has a strong load-bearing capacity. Therefore, the maintenance frequency is low and costs can be saved. Finally, the three-dimensional quenching forklift 9 is dragged The descending material fork 903 exits the furnace body 3 to complete the delivery of the quenching material cart 6. Similarly, when the quenching material cart 6 is transported outward, it is lifted by the lifting of the material fork 903, wherein the internal power of the lifting mechanism 902 is only responsible for straightening the material fork 903, thereby reducing the manufacturing cost of the lifting mechanism 902. At the same time, because the material fork 903 is evenly supported by the telescopic support mechanism 904 at the bottom, it will not bend, thereby achieving the goal of lengthening the quenching furnace and still smoothly completing the handling of the goods, thereby increasing the area of ​​the quenching furnace body 3 and being able to accommodate more metal parts to improve the quenching efficiency.

[0025] To summarize, the forklift quenching furnace is evenly installed with multiple telescopic support mechanisms 904 driven by a reduction motor 908 to synchronously rise and fall at the bottom of the material fork 903 to support the material fork 903 and change its height, so that the bottom of the material fork 903 has enough support points and will not bend even if it is very long, thereby achieving the goal of making the quenching furnace longer and still being able to smoothly complete the handling of goods, thereby increasing the area of ​​the quenching furnace body 3 and being able to accommodate more metal parts to improve the quenching efficiency. Since the support column 4 is composed of a high-aluminum brick at the bottom and a heat-resistant cast steel part at the top and is reliably fixed, its structure matches the loading and transfer quenching material cart 6 to ensure that its surface strength is sufficient to withstand weight impact, and is not easy to crack and has a strong load-bearing capacity, so the maintenance frequency is low and costs can be saved.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
