The invention discloses a rope pressing device and a crane, relates to the technical field of construction machinery and solves the technical problem that range of application is narrow caused by the fact that swing angle of a rope pressing rod is limited in prior art. The rope pressing device comprises a frame body, a rope pressing plate, a movable shaft and a motion drive mechanism, wherein an abutting portion is arranged at one end of the rope pressing plate, a sliding groove is arranged at the other end of the rope pressing plate, one portion of the rope pressing plate, which is arranged between the abutting portion and the sliding groove, is movably connected with the frame body, the rope pressing plate can rotate relative to the frame body around a movable connection position, the movable shaft is embedded in the sliding groove, the motion drive mechanism can drive the movable shaft to slide in the sliding groove, and the rope pressing plate is driven by the movable shaft to rotate relative to the frame body around the movable connection position. The crane comprises the rope pressing device. According to the rope pressing device and the crane, the range of the application of the rope pressing device is widened, and the service life of an air pump is prolonged.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a rope press and a crane provided with the rope press. Background technique [0002] In machinery such as hoisting machinery, the hoist can complete the traction action by taking in and releasing the rope. If you do not apply a certain compressive force to the cable on the winch (or drum), it is likely that the rope will be messed up. Disordered ropes will not only affect normal production operations, but also damage the quality of the ropes. [0003] In the traditional technology, the hoist is equipped with its own spring rope pressing device. Although the spring rope pressing device that comes with the hoist has certain advantages, the spring rope pressing device that comes with the hoist is limited by the structural characteristics of the spring. The Chinese patent document with the patent number of 200620113859.4 provides a rope presser, which is similar in pr...
