Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically to a connector tensioning device for replacing wire ropes in gantry cranes. Background Technology

[0002] A connector tensioning device is needed for replacing wire ropes on gantry cranes. During wire rope replacement, ensuring the new wire rope is securely attached to the crane and can withstand sufficient tension is crucial. Traditional replacement methods have drawbacks, such as requiring multiple people, being time-consuming, demanding, and potentially failing to ensure uniform wire rope tension. Therefore, a connector tensioning device is needed to simplify the replacement process, improve efficiency, and ensure safety.

[0003] In existing technology, the device has internal fixed and movable parts that can be moved relative to each other to connect the wire rope and the quick connector respectively. The movable part is used to control the relative proximity or distance of the movable part from the fixed part to achieve tension and fixation of the wire rope and quick connector, ensuring that the wire rope and connector remain stable after tensioning and will not loosen or fall off. However, in actual use, when faced with wire ropes of different types and sizes, this device only controls the relative proximity of the movable part to complete the fixation, and therefore cannot adjust the appropriate tension according to the type of wire rope. This makes it easy for the wire rope to loosen or fall off during the fixation process, resulting in safety hazards. Therefore, there is a need to improve the connector tensioning device for replacing wire ropes in gantry cranes. Utility Model Content

[0010] Preferably, a groove is provided at the position corresponding to the sliding block, and the sliding block is slidably connected in the groove, which facilitates the movement of the sliding block.

[0011] Preferably, the connecting rod is rotatably connected to the top of the connecting plate, and the push frame has a groove at the corresponding position of the slider, and the slider is slidably connected in the groove, which facilitates the adjustment of the slider's moving position.

[0014] Compared with the prior art, this utility model provides a connector tensioning device for replacing wire ropes in gantry cranes, which has the following advantages:

[0015] This connector tensioning device for replacing wire ropes in gantry cranes uses a tensioning clamping mechanism to activate hydraulic push rod two, causing its fixing pad to gradually approach the wire rope, thus fixing different types of wire ropes. After fixing, hydraulic push rod one is activated, which simultaneously pulls the fixing plate to move, and the fixing plate then simultaneously pulls the slide block to move, thereby driving the wire rope on the clamping assembly to move synchronously. This allows the device to adjust its movement position according to the required tension force, and thus adjust the appropriate tension according to the type of wire rope, preventing loosening or detachment during the fixing process.

[0016] The connector tensioning device for replacing wire ropes in gantry cranes uses a positioning mechanism to activate an electric push rod. During the rotation of the limit plate, the adjusting column is restricted by the arc groove corresponding to the limit plate, which in turn drives the positioning block to move relative to the limit plate. This causes the positioning block to drive the guide rollers to move relative to the limit plate, thereby adjusting the appropriate conveying width according to the wire rope size.
