The invention discloses a crane and a joint operating device thereof. The joint operating device is used for joint operating of first and second car bodies; the joint operating device comprises a connecting rod and a connecting base, wherein the connecting rod is arranged on the first car body; the connecting rod comprises a tapered part; the tapered part comprises a flat end and a tapered end; the diameter, at the flat end, of the connecting rod is maximal; the connecting base is arranged on the second car body; the connecting base comprises an upper connecting base and a lower connecting base which is hinged with the upper connecting base through a hinge assembly; the first sides of the upper and the lower connecting bases are respectively provided with upper and lower jaws; a clamping space used for accommodating and clamping the tapered part is formed between the upper and the lower jaws; the lower jaw or both the lower jaw and the upper jaw are provided with a slide block which is retracted while pressed and is ejected while un-pressed; the second side of the upper connecting base is provided with a first magnetic device; the second side of the lower connecting base is provided with a second magnetic device; and at least one of the first magnetic device and the second magnetic device is an electromagnet. The joint operating device can be used for improving the joint operating efficiency.
Description
technical field [0001] The invention relates to crane equipment, in particular to a paralleling device and a crane with the paralleling device. Background technique [0002] In the prior art, there is a requirement for parallel operation between the double trolleys on the crane, or between the double bridge cranes. The paralleling here can also be called interlocking. [0003] For example, the paralleling device of the bridge crane of the hydropower station is used for the paralleling between the bridge cranes of the two hydropower stations. The paralleling device is mainly composed of three parts: the connecting rod 6, the nut 7 and the connecting seat 5. When the bridge cranes of two hydropower stations are converted from independent operation to parallel operation, operators need to board figure 1 The bridge crane of the hydropower station on the left will figure 1 The connecting rod 6 and the figure 1 Connect the connecting seat 5 of the bridge crane of the hydropowe...
