Description

Technical Field

[0001] The utility model relates to a three-stream slab roller table motor reducer guard, belonging to the technical field of conveying roller tables of three-stream slab continuous casting machines in the metallurgical industry. Background Art

[0002] During the three-stream slab production process, since the hot cast billet is close to the roller motor reducer, and the temperature of the hot cast billet is about 800°C, the baking temperature of the hot cast billet of the motor reducer is above 200°C. The 320# gear oil in the reducer is affected by the high temperature and cannot achieve the lubrication effect, thus affecting the service life of the reducer. At the same time, the motor is in a high temperature environment for a long time, and the life of the internal insulation layer will be seriously shortened.

[0003] Therefore, a three-stream slab roller motor reducer guard is needed to improve the above problems. Utility Model Content

[0004] The utility model aims to provide a three-stream slab roller motor reducer shield, which can provide heat insulation protection for the motor reducer, thereby increasing its service life and solving the problems existing in the background technology.

[0005] The technical solution of the utility model is:

[0006] A three-stream slab roller motor reducer shield comprises a shield body, an observation door mechanism and a carrying handle, wherein the shield body is provided with an observation door mechanism on the top, the left and right sides of the shield body are provided with carrying handles and through holes, and the front and rear of the shield body are provided with through grooves penetrating the shield body, and the size of the through grooves matches the size of the three-stream slab roller motor reducer.

[0007] Furthermore, the shield body comprises a keel frame formed by welding square tubes, inner and outer steel plates welded in the keel frame, and asbestos fiberboard filled between the inner and outer steel plates.

[0008] Furthermore, the observation door mechanism on the shield body comprises an observation door, a hinge seat and a handle. The observation door is hinged to the shield body through the hinge seat, and the observation door is provided with a handle.

[0009] The utility model has the beneficial effects of completely wrapping the roller motor reducer, completely isolating the hot casting billet from baking the bearing seat and the motor reducer, thereby increasing their service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0016] See attached Figure 1-4 A three-stream slab roller motor reducer shield comprises a shield body 1, an observation door mechanism 2 and a carrying handle 4. The shield body 1 is provided with an observation door mechanism 2 on the top, and the left and right sides of the shield body 1 are provided with carrying handles 4 and through holes 3. The front and rear of the shield body 1 are provided with through grooves 8 that penetrate the shield body 1, and the size of the through grooves 8 matches the size of the three-stream slab roller motor reducer.

[0017] In this example, refer to the attached Figure 1-4 In order to reduce the weight of the shield itself and facilitate carrying, the shield body 1 uses 20*20*2 mm square tubes to make a keel frame, welds inner and outer 1.5 mm steel plates in the keel frame, and fills 20 mm asbestos fiberboard between the inner and outer steel plates as an insulation layer.

[0018] The observation door mechanism 2 on the shield body 1 includes an observation door 5, a hinge seat 6 and a handle 7. Several hinge seats 6 are hinged on one side of the observation door 5. The observation door 5 is hinged to the upper surface of the shield body 1 through the hinge seat 6. A handle 7 is fixedly connected to one side of the upper surface of the observation door 5.

[0019] A carrying handle 4 is fixedly connected to both left and right sides of the shield body 1, and through holes 3 are symmetrically opened.

[0020] A through groove 8 penetrating the shield body 1 is provided at the front and rear of the shield body 1 , and the size of the through groove 8 matches the size of the motor reducer of the three-stream slab roller table.

[0021] Working principle: The shield body 1 is installed on the roller motor reducer through the through groove 8. The shield body 1 can be placed and taken out conveniently through the carrying handle 4. When in use, the interior can be quickly judged by opening the observation door 5.
