Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1 to 3, this embodiment aims to provide a self-tightening type locking mechanism for a furnace door 1, which solves the problem that the locking mechanism for a vertical furnace door 1 of various existing heat treatment furnaces, forging furnaces, drying furnaces and the like is inconvenient to install or operate, and for this purpose, the self-tightening type locking mechanism for a furnace door 1 provided by this embodiment includes a furnace door 1 and a lifting ring 11 disposed on the top of the furnace door 1, the lifting ring 11 is mainly used for connecting a lifting chain to lift the furnace door 1, pulleys 12 are disposed on both sides of the furnace door 1, in this embodiment, rotating shafts are welded on both sides of the furnace door 1, the pulleys 12 are rotatably disposed on both sides of the furnace door 1 through the rotating shafts, in this embodiment, two sets of pulleys 12 are disposed up and down, slides 2 matched with the pulleys 12 are further disposed on both sides of the furnace door 1, the slides 2 include a linear slide 21 for linearly lifting the furnace door 1 and, in this embodiment, the linear slideway 21 is H-shaped steel, and the curved slideway 22 is H-shaped steel with a certain curvature, of course, the curved slideway 22 may be made into a linear inclined form, or an arc inclined form, and the inclined angle range is greater than 0 degree, smaller than 90 degrees, and generally set between 30-60 degrees. The curved slideway 22 is arranged on one side of the linear slideway 21, more specifically, the curved slideway 22 is arranged on the side close to the furnace body, and the curved slideway 22 is communicated with the linear slideway 21. Therefore, the furnace door 1 descends linearly through the linear slideway 21 in the descending process, when the furnace door 1 reaches the curve slideway 22, the furnace door 1 can not only descend continuously, but also the pulley 12 drives the furnace door 1 to do horizontal movement along the curve slideway 22 which is bent obliquely, at the moment, the direction of the horizontal movement of the furnace door 1 faces the furnace body, the furnace door 1 descends and presses tightly to the furnace body, and thus, the self-gravity of the furnace body is utilized to achieve the function of automatic sealing.

In order to further improve the sealing effect, an auxiliary locking mechanism 3 is further arranged on the linear slideway 21, specifically, the auxiliary locking mechanism 3 comprises a supporting rod 31 rotatably arranged on the linear slideway 21, the supporting rod 31 is arranged in a whole rectangular plate shape, a turning ring 32 is arranged at one end, away from the linear slideway 21, of the supporting rod 31, the turning ring 32 has the same function as the lifting ring 11, therefore, a steel wire rope 33 is connected to the turning ring 32, a fixed pulley 34 used for guiding the steel wire rope 33 is arranged on the linear slideway 21, and a hoisting device is arranged at one end, away from the turning ring 32, of the steel wire rope 33, so that the steel wire rope 33 is wound by the hoisting device to drive the supporting rod 31 to turn over, meanwhile, the steel wire rope 33 also plays a certain limiting role, and the aim of keeping the supporting rod 31 and the linear track in a 90-degree vertical state.

In order that the tightening rod 31 can automatically turn over under the action of gravity without other power, in the embodiment, the tightening rod 31 is rotatably arranged on the linear slideway 21 through a bearing 35. The purpose of setting like this is exactly in order to improve the flexibility ratio of supporting pole 31, makes things convenient for it to overturn under self gravity, in addition, at the in-process that hoisting equipment draws supporting pole 31, supporting pole 31 need not draw 90, break away from furnace gate 1 can.

In addition, the abutting rod 31 is not in close contact with the oven door 1, and if the abutting rod is in close contact with the oven door 1, the abutting rod cannot be turned down, and a small gap is kept between the abutting rod and the oven door 1 for the sake of time and demand.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
