AI Technical Summary
The existing metallurgical crane track splicing method is hot melt welding, which is prone to welding of joints due to thermal expansion and contraction or vibration of the sky truck, causing uneven tracks and severe wear of the sky truck wheels.
The new splicing structure of metallurgical crane tracks is adopted, and a more stable connection is achieved through the combination of interconnected guide rails, clamps and bolt nuts.
This splicing structure can effectively alleviate the vibration of the sky truck passing through the joint, extend the service life of the wheel, reduce the intensity of maintenance labor, and improve operating efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crane running rails in the metallurgical industry, in particular to a novel splicing structure of metallurgical crane rails. Background Art
[0002] The splicing of metallurgical crane rails can extend the length of the rails and firmly connect the two rails together, which can ensure that the plane and side of the rails are in a straight line and level, ensure the smooth passage of the overhead crane, extend the overhead crane operating area, and ensure the life of the wheels.
[0003] However, the existing metallurgical crane rail splicing method is generally hot-melt welding, which has certain shortcomings: due to thermal expansion and contraction or vibration of the overhead crane during travel, the joints are easily welded, making the rails not in the same horizontal plane, causing serious wear of the overhead crane wheels. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a new splicing structure of metallurgical crane rails. The spliced metallurgical crane rails can alleviate the vibration of the overhead traveling block joint and are easy to replace using bolt connections.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:
[0006] A novel splicing structure of a metallurgical crane rail includes a guide rail 1 and a guide rail 2 connected to each other, and also includes a clamping plate and bolts and nuts; the two clamping plates are arranged on both side surfaces of the connection between the guide rail 1 and the guide rail 2 in a front-to-back mirror-image manner, and the two clamping plates are simultaneously connected and fixed to the guide rail 1 or the guide rail 2 by bolts and nuts.
[0007] As an improvement, the two ends of guide rail one form a convex-shaped joint part one, and the two ends of guide rail two form a convex-shaped joint part two. After guide rail one and guide rail two are connected, a splint is placed in the two grooves formed between joint part one and joint part two.
[0008] As an improvement, a tenon is reserved on the top surface of the convex plate body of the joint part one, and a mortise is reserved on the bottom surface of the convex plate body of the joint part two. The joint part one and the joint part two are spliced together by the engagement of the tenon and the mortise.
[0009] As an improvement, the two clamping plates are fixed together with the convex plate body of the joint part one or the convex plate body of the joint part two by bolts and nuts.
[0010] The advantages of the utility model compared with the prior art are:
[0011] The two adjacent metallurgical crane rails are first joined with mortise and tenon joints, and then connected by means of the cooperation of plywood, bolts and nuts. This splicing method reduces vibration during the operation of the overhead crane, extends the service life of the wheels, reduces maintenance labor intensity, and improves operating efficiency.

[0016] In the description of the present utility model, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.
[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0018] The new splicing structure of metallurgical crane rails includes:
[0019] The guide rail 1 and the guide rail 2, the clamping plate 3 and the bolts and nuts 4 are connected to each other; the two clamping plates 3 are arranged on both sides of the connection between the guide rail 1 and the guide rail 2 in a mirror-image manner, and the two clamping plates 3 are connected and fixed to the guide rail 1 or the guide rail 2 by the bolts and nuts 4. Specifically:
[0020] The two ends of the guide rail 1 form a convex joint part 1 5, and the two ends of the guide rail 2 form a convex joint part 2 6. After the guide rail 1 and the guide rail 2 are butted, a clamping plate 3 is placed in the two notches formed between the joint part 1 5 and the joint part 2 6. A tenon 7 is reserved on the top surface of the convex plate body of the joint part 1 5, and a mortise 8 is reserved on the bottom surface of the convex plate body of the joint part 2 6. The joint part 1 5 and the joint part 2 6 are spliced together through the bite of the tenon 7 and the mortise 8. The two clamping plates 3 are fixed together with the convex plate body of the joint part 1 5 or the convex plate body of the joint part 2 6 by bolts and nuts 4.
[0021] In the specific implementation of this embodiment:
[0022] The new splicing structure uses the old rails to make the plywood holes, cuts off the original hot-melt welded rail joints, aligns the guide rail 1 and guide rail 2 2 to be installed, and then fixes the two plywoods 3, joint part 1 5 and joint part 2 6 together. After installation, the surface and sides of the plywood 3 are polished smooth, and the crane workers are contacted for a test run to ensure that the crane is operating normally. This work is completed.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
