[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The present invention provides a walking-beam heating furnace provided with a frame-type compact walking mechanism, comprising a walking-beam heating furnace body and a frame-type compact walking mechanism, the frame-type compact walking mechanism comprising a translation structure 1 and a lifting structure 2, the translation structure 1 comprising a translation drive device 103 and a plurality of translation units, each translation unit comprising a translation frame 101 and a translation roller 102, the lifting structure 2 comprising a lifting frame 201, a lifting roller 202, a lifting drive device 203 and an inclined rail seat 204, a translation unit is arranged under each group of movable beams 3 of the walking-beam heating furnace body, the front and rear ends of the translation frame 101 are respectively connected to a group of translation units. The translation rollers 102 are connected to each other, and the adjacent translation frames 101 are connected to each other. The translation drive device 103 is connected to the translation frame 101 at the end, and the translation frame 101 is fixedly connected to each group of movable beams 3 at the corresponding position; a group of lifting rollers 202 are arranged at a certain distance on the lifting frame 201, and all the translation frames 101 are arranged inside the lifting frame 201. The inner side of the lifting frame 201 is a groove structure. Each group of translation rollers 102 is installed in the groove structure of the lifting frame 201, and the lifting drive device 203 is connected to one end of the lifting frame 201. Each group of lifting rollers 202 is matched with a ramp seat 204.

[0025] refer to Figure 8During the operation of the walking beam heating furnace body, the movable beam 3 is first in position A. After starting to move, the lifting drive device 203 first drives the lifting frame 201, so that the lifting frame 201 drives the lifting roller 202 to perform an upward movement on the inclined rail seat 204. At this time, driven by the lifting frame 201, the translation frame 101 and the translation roller 102 also perform an upward movement as a whole. At the same time, under the action of the translation drive device 103, the translation roller 102 and the translation frame 101 perform a uniform opposite movement relative to each other, and the speed is consistent. Therefore, during the lifting process, the translation structure 1 only performs an upward movement without a translation movement. After reaching the highest point, the movable beam 3 reaches point B, and the translation drive The device 103 drives the translation frame 101, so that the translation frame 101 drives the translation roller 102 to perform forward translational motion, and the movable beam 3 reaches position C. The lifting drive device 203 drives the lifting frame 201 to descend on the inclined rail seat 204. At this time, the translation roller 102 and the translation frame 101 perform relative motion, that is, the horizontal position of the entire translation frame 101 does not change, but only lowers. After reaching the lowest point, that is, the movable beam reaches position D, the translation drive device 103 drives the translation frame 101, and the translation frame 101 drives the translation roller 102 to perform backward motion in the lifting frame 201 to the initial position, that is, the movable beam 3 returns to position A, ending a stepping action.

[0026] To achieve consistent drive, as an improvement to the technical solution, each translation frame 101 is connected to a translation frame sub-assembly 104 at its front and rear ends, and two adjacent translation frames 101 are connected together via the translation frame sub-assembly 104. During movement, because different translation frames 101 are connected together via the translation frame sub-assembly 104, overall drive is achieved through the drive of only one translation drive device 103.

[0027] In order to reasonably connect the movable beams 3, as an improvement of the technical solution, each of the translation frames 101 is provided with sleeves 105 with the same number as the movable beams 3 in each group of movable beams 3, and the lower end of each movable beam 3 extends into the sleeve 105 and is fixed in the sleeve 105.

[0028] In order to reasonably arrange the stepping mechanical structure, as an improvement of the technical solution, a steel structure 4 is fixedly provided below the walking beam heating furnace body, and the lower end of each of the inclined rail seats 204 is fixedly mounted on the steel structure 4.

[0029] The furnace bottom steel structure 4 supports the furnace bottom water beam columns and the heating furnace bottom and the furnace bottom stepping mechanical equipment system. The frame-type compact stepping machinery provided by the present invention can be installed on the construction site after being manufactured in the manufacturer or can be installed directly on the construction site, which is convenient for manufacturing, installation, construction and disassembly for maintenance, and has good economic benefits.

[0030] In order to prevent the lifting roller 202 from detaching from the inclined rail seat 204 during movement, as an improvement to the technical solution, a stopper 2041 is provided at the lowest end of the inclined rail seat 204. Each inclined rail seat 204 is a right-angled triangle structure, and the acute angle of the inclined rail seat 204 at the bottom is 11-30°.

[0031] Preferably, both the translation drive device 103 and the lifting drive device 203 are hydraulic drive devices.

[0032] In order to enhance the strength, as an improvement to the technical solution, the lifting frame 201 is a frame structure composed of forklift gantry channel steels, which are firmly connected to the frame structure by connecting steel plates.

[0033] The forklift mast channel steel has strict design precision requirements and stable dimensions, strong load-bearing capacity, and is formed in one step through hot rolling during the production process. It can withstand heavy tonnage and is a lifting frame composed of a large-load-bearing forklift mast channel steel frame and steel plate components. The structure is compact, simple and stable, and it saves production and manufacturing space.

[0034] The present invention is preferably applicable to small walking beam heating furnaces, such as copper billet walking beam furnaces, and meets the economic cost requirements of small walking beam heating furnaces. At the same time, it also ensures the safety and stability of the billet movement in the heating furnace, has a simple structure, and good economic benefits.
