Description

Technical Field

[0001] This utility model relates to the field of monorail crane technology, and more specifically, it relates to an anti-derailment guiding mechanism for an electric single-girder crane. Background Technology

[0002] In the field of industrial lifting equipment, electric single-girder cranes are widely used in material handling operations in workshops, warehouses, and logistics scenarios due to their advantages such as compact structure, flexible operation, and low cost. Among them, the electric hoist, as the core lifting mechanism, directly affects the overall safety and operational efficiency of the crane. However, the guiding mechanisms of existing electric single-girder cranes generally suffer from the following technical defects: Currently, under eccentric loading conditions, such as when the load is offset or pulled at an angle, the running wheel assembly of electric hoists on the market is prone to contact between the wheel and the rail on one side due to concentrated lateral force. Over time, this can lead to wheel flange wear or even derailment. In addition, track installation errors or local deformation caused by long-term use, such as track bending or height differences, can further aggravate abnormal contact between the wheel and rail, making derailment problems more frequent.

[0003] Uneven loading or track deformation can cause abnormal friction between the wheels and the sides of the track, which not only produces a harsh noise, but also accelerates the wear of wheels, tracks and structural components, shortens the service life of the equipment, increases running resistance, and causes secondary failures such as motor overload. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-derailment guide mechanism for an electric single-girder crane that can correct the deviation of the electric hoist.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0016] Please see Figure 1-5 The present invention provides the following technical solution: Example 1: To address the problem that electric hoist 2 is prone to derailment during long-term operation and requires frequent manual adjustment and reset.

[0017] The electric single-girder crane includes a crossbeam 1 and an electric hoist 2 slidably mounted on the crossbeam 1. The anti-derailment guiding mechanism of the electric single-girder crane also includes a correction mechanism 3. The correction mechanism 3 is located on the top of the electric hoist 2. The correction mechanism 3 includes a pushing part 31, a limiting part 32, and a limiting wheel 33. The pushing part 31 is slidably mounted on the top of the electric hoist 2. The limiting part 32 is located on the top of the crossbeam 1. The limiting wheel 33 has a pair and is rotatably mounted on the top of the pushing part 31. The limiting part 32 has a groove on its side for the limiting wheel 33 to rotate. When the pushing part 31 moves, it can drive the limiting wheel 33 to move.

[0018] First, when one side of the electric hoist 2 tilts, the pushing part 31 located at the top of the electric hoist 2 moves towards the crossbeam 1. It should be noted that in this embodiment, the limiting wheel 33 can slide inside the abutment groove below the limiting part 32. Therefore, when the pushing part 31 moves, it synchronously drives the limiting wheel 33 to move synchronously. When one side of the electric hoist 2 derails or tilts, the pushing part 31 at the top of the electric hoist 2 drives the limiting wheel 33 to move away from the limiting part 32, and drives the limiting wheel 33 to slide synchronously within the abutment groove below the limiting part 32. The limiting wheel 33 then abuts against the inner wall of the abutment groove. The pushing part 31 continues to move, applying a reverse thrust to the derailed side of the electric hoist 2 through the abutment force, thereby driving the hoist back to the center position of the track, achieving automatic reset. This solves the problem of derailment and track wear caused by long-term wear, uneven loading, or impact during single-rail operation of the electric hoist 2. This solution resolves the derailment and rail wear issues caused by uneven loading, swaying, or track deformation of the electric hoist 2, significantly reducing the need for manual adjustments and ensuring continuous, stable, and safe operation of the equipment.

[0019] See Figures 3-5 The crossbeam 1 is an I-beam structure, and the lower two sides of the crossbeam 1 extend outwards to power the electric hoist 2 to slide.

[0020] The crossbeam 1 is made of standard I-beam steel, and the lower flanges extending from both sides of the crossbeam 1 provide a stable and reliable sliding track for the traveling wheels of the electric hoist 2. This common structure ensures the versatility and support strength of the equipment and serves as the basic platform for the installation and operation of the correction mechanism 3.

[0021] See Figures 3-5 The correction mechanism 3 also includes a connecting plate 34 and an electric push rod 35; the connecting plate 34 is located on the top of the electric hoist 2 and is located beside the pushing part 31; there is a pair of electric push rods 35, which are respectively located beside the connecting plate 34, and the output ends of the pair of electric push rods 35 are connected to the pushing part 31. When the electric push rods 35 are started, they can drive the pushing part 31 and the limiting wheel 33 to move synchronously.

[0022] After the electric push rod 35 is started, the output end of the electric push rod 35 directly pushes the pushing part 31 to move horizontally, thereby driving the limit wheel 33 to slide in the abutment groove, providing power for subsequent abutment and correction actions.

[0023] See Figure 5 The correction mechanism 3 also includes a support plate 36; the support plate 36 has a pair and is respectively disposed on the side of the pushing part 31, and the end faces of the pair of support plates 36 are fixedly connected to the connecting part, and the pair of support plates 36 are inclined.

[0024] To support the connection strength between the connecting part and the pushing part 31 and ensure the service life of the pushing part 31, a pair of support plates 36 are respectively disposed at the bottom of the pushing part 31. The end faces of the pair of support plates 36 are fixedly connected to the connecting part, and both of the support plates 36 are inclined so that the pair of support plates 36 can stably support the connection between the pushing part 31 and the connecting part in a triangular structure.

[0025] See Figure 5 The pushing part 31 is a horizontally arranged plate-like structure.

[0026] The horizontal plate-shaped pushing section 31 provides a stable mounting base for the limiting wheel 33 and ensures sufficient contact area with the top of the electric hoist 2. This allows the thrust transmitted by the electric push rod 35 to act evenly on the electric hoist 2.

[0027] See Figure 5 The limiting part 32 is fixedly installed on the top of the crossbeam 1, and the cross section of the limiting part 32 is a lateral U-shaped structure.

[0028] The inverted U-shaped limiting part 32 naturally forms an abutment groove that constrains the movement path of the limiting wheel 33 through its internal cavity. The structure is simple and highly integrated, and there is no need to process complex grooves, which ensures the accuracy of the guiding and correction process of the limiting wheel 33.

[0029] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
