FIELD: power engineering. ^ SUBSTANCE: device of furnace loading and unloading for thermal treatment, comprising a frame structure (20) with the first upper and second lower plane (21, 22), which are arranged in parallel one above the other and are connected to each other by means of multiple frame stands (23), at the same time each first and second planes (21, 22) has multiple holes (21a, 22a). At the same time the frame stands have multiple guide facilities (25), multiple lifting stands (31), which are connected with the lifting device (34) and are vertically mounted with the possibility of displacement in guide facilities (25) of the frame stands (23) and pass vertically above the upper plane (21). At the same time the lifting stand (31) has a bearing element (35, 36), which in the first position corresponds to the upper plane (21), in the second position it corresponds with the appropriate lower plane (22), at the same time the bearing elements (35, 36) are aligned at the lifting stands (31) so that they are displaced into holes (21a, 22a) in the specified planes, when the vertical displacement of the lifting stands (31) takes place, and at least one stop facility arranged on the frame stand (23) limits the vertical displacement of the appropriate lifting stand (31). ^ EFFECT: prevention of oil ingress into furnace in process of stocks charging in it. ^ 12 cl, 6 dwg |
