Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The following describes the battery replacing hanger 100 and the battery replacing station according to the present invention with reference to fig. 1-2. It can be understood that the electric automobile can be an engineering vehicle such as a heavy truck, and the battery can be replaced for the electric automobile by the battery replacement station. The battery replacing lifting tool 100 can grab the battery and replace the power battery for the electric automobile. For example, the battery replacement hanger 100 hoists the power battery 200 from the top of the electric vehicle to hoist the insufficient battery to the charging position for charging, and meanwhile, hoists the full battery to the electric vehicle, so as to achieve the purpose of replacing the battery for the electric vehicle. The spreader 120 may be connected to the cross beam of the battery replacement spreader 100 by a flexible member such as a steel rope, and the spreader 120 may move up and down by a hoist. But the lifting appliance 120 can swing during the horizontal movement, and the unstable movement can affect the electricity changing process and even cause safety problems. It is therefore necessary to provide means for securing the spreader 120. The positioning pin 140 can fix the spreader 120 in a manner of matching with the positioning hole, so as to prevent the spreader 120 from shaking during horizontal movement.

Referring to fig. 1, according to the utility model discloses trade electric hoist 100, include: spreader beam 110, spreader 120, connecting structure 130, and positioning pin 140.

Specifically, the spreader 120 is connected to the spreader beam 110 by a connection structure 130. The connection structure 130 may have a certain flexibility to facilitate the storage or release of the connection structure 130 by the hoist, thereby facilitating the adjustment of the height of the spreader 120. For example, one end of the connection structure 130 is fixedly connected to the spreader 120, the other end of the connection structure 130 is connected to the spreader beam 110, and the other end of the connection structure 130 can adjust the length of the connection structure 130 to raise or lower the spreader 120. Be equipped with location portion 121 on hoist 120, location portion 121 is used for cooperating with the positioner on the hoist crossbeam 110 to fixed hoist 120 when trading electric hoist 100 horizontal migration prevents that hoist 120 from appearing rocking.
