Description

Technical Field

[0001] The utility model relates to a full-electric single-arm crane, belonging to the technical field of oil drum transport arm cranes. Background Art

[0002] In the process of transporting oil drums, oil drum transporters are usually divided into fully electric and semi-electric. Both types of oil drum transporters have the structural function of transporting and lifting oil drums, but their lateral transport area is limited and they cannot lift oil drums that are far away and high. The existing single boom used for oil drum transporters has a single structure, poor operating stability, a small lifting range, and cannot meet the needs of lifting and transporting oil drums at far and near by telescopic means. Therefore, a fully electric single-arm crane is proposed to address the above problems. Utility Model Content

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: a fully electric single-arm crane, including a cylinder arm, a lifting arm and a hook, guide seats are installed on both sides of the cylinder arm, and each guide seat is slidably connected to the corresponding guide rail on the lifting arm, a side groove is opened on one side of the lifting arm located in the cylinder arm, and a screw hole block is installed at one end of the side groove, the screw hole block is threadedly connected to the lead screw located in the side groove, and one end of the lead screw is connected to the motor located in the motor installation room, and the bearing seats located on the inner sides of both ends of the lead screw are fixedly connected to the corresponding parts of the cylinder arm through connecting bolts.

[0005] Furthermore, the bearing seat is located at a corresponding position in the side groove.

[0006] Furthermore, a motor installation chamber is provided on the rear end side wall of the cylinder arm, and a cover is installed on the port of the motor installation chamber.

[0007] Furthermore, a lift connecting frame is welded to the bottom of the rear end of the cylinder arm, and an end protection piece is installed at the cylinder mouth of the cylinder arm.

[0008] Furthermore, a connecting block is welded on the end surface of one end of the boom, and a hook is movably installed on the bottom end of the connecting block.

[0009] Furthermore, the upper and lower surfaces of the boom are in sliding contact with the upper and lower wall surfaces inside the cylinder arm respectively.

[0010] Compared with the prior art, the advantages of the utility model are: the side groove on one side of the boom is convenient for installing the lead screw, and a motor connected to the lead screw is configured to achieve the effect of driving the boom to extend and retract, thereby increasing the lifting range. At the same time, the two sides of the boom are connected to the two sides of the barrel arm through guide rails and guide seats that are slidably connected to each other, thereby enhancing the stability of the lifting and telescopic operation. By placing the ends of the connecting bolts connecting the bearing seats on both sides of the lead screw and the barrel arm outside, disassembly and assembly are more convenient.
