Description

Technical Field

[0001] The utility model relates to the technical field of kiln equipment, in particular to a kiln hoist with stable lifting function. Background Art

[0002] Kilns come in a variety of structural forms. One type of kiln has a multi-layer structure, with each layer equipped with a set of conveyor rollers. The external conveyor rollers are fixed, and an elevator is generally required. When discharging materials, the elevator drives the kiln up and down so that the height of the conveyor rollers of the corresponding layer of materials aligns with the external conveyor rollers. However, existing elevators have the following problems in actual use: the heights of the four corners may be out of sync, causing the conveyor rollers to tilt, which in turn causes the conveyor rollers to not be fully aligned with the external conveyor rollers. As a result, the material in the furnace cannot be discharged smoothly, or there may be jamming or collisions during discharging, affecting normal production. Summary of the Invention

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned prior art and to provide a kiln hoist that can be lifted and lowered smoothly.

[0004] The specific scheme of the utility model is: a kiln hoist with smooth lifting, including a fixed frame, each of the four corners of the fixed frame is provided with a column, the inner side of each column is provided with a guide rail along the length direction, and a lifting platform is commonly provided on the four guide rails. The lifting platform is used to carry the kiln, and the side of the lifting platform is provided with guide wheels corresponding to each guide rail. A traction connecting piece is respectively provided at the four corners of the lifting platform, a reduction box is respectively provided at the middle of both sides of the top of the fixed frame, and a driving motor is respectively provided at the input end of the two reduction boxes, and an output shaft is respectively provided on both sides of each reduction box. The output shaft extends to the four corners of the lifting platform and is connected to a hoisting mechanism. The wire rope of each hoisting mechanism is connected to the corresponding traction connecting piece below.

[0005] Furthermore, the input shafts of the two reduction gearboxes extend toward the center and are connected as one.

[0006] Furthermore, two bearing seats are provided at the center of the top of the fixing frame, and the input shafts of the two reduction gearboxes pass through the corresponding bearing seats respectively, and the ends of the two input shafts are fixed by flange connection.

[0007] Furthermore, each of the four corners of the lifting platform is equipped with a guide wheel seat, and each guide wheel seat is equipped with a plurality of guide wheels, and the guide wheels are arranged from top to bottom.

[0008] The utility model has the following beneficial effects: by setting two sets of reduction gearboxes and output shafts, the hoisting mechanisms at the four corners are hard-connected, thereby achieving synchronous lifting of the four corners of the lifting platform, avoiding height asynchrony during the lifting of the four corners, and thus meeting the needs of smooth discharge.
