Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a hydraulic coupler hoisting device. Background Art

[0002] A hydraulic coupling, also known as a hydraulic coupling, is a hydraulic transmission device used to connect a power source (usually an engine or motor) to a working machine and transmit torque by the change of the liquid's kinetic energy.

[0003] Lifting device refers to the general term for the installation and positioning of equipment by the lifting mechanism. During the inspection or maintenance process, various lifting machines are used to lift equipment, workpieces, tools, materials, etc. to change their position.

[0004] For example, the utility model patent with publication number CN221971068U discloses a hydraulic coupler lifting device, which includes a convex frame, the front and rear ends of the top of the convex frame are fixedly connected to guard plates, the inner walls of the guard plates are fixedly connected to four pulleys, the two sides of the bottom of the convex frame are fixedly connected to base plates, and the two sides of the convex frame are fixedly connected to steering rods. The user turns on the motor switch, releases the rope to the appropriate length, pulls the plug plate out of the inside of the socket, separates the pallet to both sides, places it at the bottom of the coupler, inserts the plug plate into the inside of the socket, merges the pallets together, and makes it easier for the user to fix the coupler to the traction device. Turn on the motor switch to retract the rope, and under the action of the pulley, the rope drives the pallet to move upward, and the coupler is lifted. The size of the internal space of the pallet is adjusted by the length of the plug plate inserted into the socket, so that the pallet can be used for couplers of different sizes. However, there is a problem that the pallet will shake during the rising and falling process, and the hydraulic coupler placed on the pallet will shake, which ultimately reduces the stability of the hydraulic coupler during the rising and falling process. For this reason, we propose a hydraulic coupler lifting device. Utility Model Content
