[0002] A rail crane is a type of lifting equipment that runs on rails and is primarily used for loading, unloading, and transporting containers. It typically travels on tracks, using a hook or boom to lift and move heavy objects. Its design allows for flexible movement along fixed tracks, making it suitable for locations like ports and docks where large volumes of cargo need to be loaded and unloaded.

[0003] The rail crane's hoisting wire rope is connected to the hoisting frame using a heavy-duty aluminum sleeve. Due to limitations in processing equipment and processes, the connectors must be manufactured externally. This increases the cost of manufacturing spare wire rope connectors, and the time it takes to obtain spare wire ropes is difficult to manage, which can affect equipment availability.

[0007] Furthermore, the end of the adjusting screw member close to the wedge-shaped sleeve structure is arranged in a circular structure, and the end of the adjusting screw member close to the wedge-shaped sleeve structure is vertically opened with a structural hole for the shaft pin structure to penetrate and install.

[0008] Furthermore, one end of the adjusting screw member is horizontally inserted into the middle of the wedge sleeve structure provided with a U-shaped fork structure, and two groups of hole structures are vertically opened on the surface of one end of the adjusting screw member away from the wedge sleeve structure.

[0009] Furthermore, the two groups of hole structures at one end of the adjusting screw member are mutually penetrated by a cross-shaped structure, and the wedge-shaped sleeve structure, the adjusting screw member, and the shaft pin structure are assembled and installed with a movable connection structure.

[0010] Furthermore, a through hole structure is horizontally opened at one end of the shaft pin structure, and a group of hole structures are vertically opened at the center of the bottom side surface of the shaft pin structure and are interconnected with the horizontal through hole structure.

[0011] Furthermore, a U-shaped channel structure for the wire rope component to pass through is opened in the middle of the inner part of one end of the wedge-shaped sleeve structure away from the adjusting screw component, and the outer surface specifications of the wire rope component match the internal channel structure of the wire rope component.

Since the structural combination between the three is relatively simple, the materials can be directly used on site for relatively fast and convenient processing and manufacturing. The processing operation is simple and convenient, and the structure can be repeatedly used to a certain extent. In this way, the service life of the device structure can be effectively guaranteed. Since the cost of the whole set of connecting mechanism is about 1,200 yuan, the service life is conservatively estimated to be 20 years. Therefore, according to the service life calculation, the cost of replacing the lifting wire rope of the rail crane after the transformation can be saved by about 40 million. The wire rope member itself can be cut and prepared by itself, and the entire joint structure can be made by itself on the rope replacement site, and the spare parts cycle is not affected by external conditions, thereby greatly ensuring the ease of use, structural flexibility and simplicity of the device structure.

In the present invention, a U-shaped channel structure for inserting the wire rope member is opened in the middle of the inner part of the wedge-shaped sleeve structure away from the adjusting screw member, and the wire rope clamp member and the fixing bolt member are arranged in combination. After the wire rope member is inserted into the channel structure inside the wedge-shaped sleeve structure, the wire rope clamp member and one end of the wedge-shaped sleeve structure can be connected with each other. At the same time, the fixing bolt member is used to screw into the connected wedge-shaped sleeve structure and the wire rope clamp member, so as to structurally clamp and fix one end of the wire rope clamp member. The arrangement of the above structure, combined with the friction force of the structural connection between the wedge-shaped sleeve structure and the wire rope member, can ensure the connection firmness between the device structure and the wire rope member to the greatest extent, and at the same time cooperate with the arrangement between each structural member, thereby ensuring the production and processing cost of the spare wire rope connector, and at the same time, it can also ensure the good control of the wire rope spare part time as much as possible, and minimize unnecessary impact on the equipment's integrity rate.

The structural setting between the wedge-shaped sleeve structure 1, the adjusting screw component 2, and the shaft pin structure 3 is adopted. Since the structural combination between the three is relatively simple, they can be directly processed and manufactured on-site with local materials for relatively fast and convenient processing. The processing operation is simple and convenient, and the structure can be repeatedly used to a certain extent. In this way, the service life of the device structure can be effectively guaranteed.

[0025] like Figures 1 to 4As shown, the two groups of hole structures at one end of the adjusting screw member 2 adopt a cross-shaped structure to penetrate each other, and the wedge-shaped sleeve structure 1, the adjusting screw member 2, and the shaft pin structure 3 are installed in combination with each other using a movable connection structure. A through-hole structure is opened horizontally through one end of the shaft pin structure 3, and a group of hole structures are opened vertically at the center of the bottom side surface of the shaft pin structure 3 and are interconnected with the horizontal through-hole structure. A U-shaped channel structure for the wire rope member 4 to be inserted is opened in the middle of the inner part of the end of the wedge-shaped sleeve structure 1 away from the adjusting screw member 2, and the outer surface specifications of the wire rope member 4 match the internal channel structure of the wire rope member 4.

[0028] Then, one end of the adjusting screw component 2 is horizontally inserted into the middle of the end of the wedge-shaped sleeve structure 1 away from the wire rope clamp component 5, and then a set of axle pin structures 3 are selected and vertically inserted into the connection between the wedge-shaped sleeve structure 1 and the adjusting screw component 2, so as to complete the rapid combination and docking between the wedge-shaped sleeve structure 1 and the adjusting screw component 2.
