Description

Technical Field

[0001] This utility model relates to a lifting device, specifically, to a fully automatic steel pipe handling crane. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Because their ends rest on tall concrete pillars or metal supports, they resemble bridges. The bridge frame of a bridge crane runs longitudinally along rails laid on elevated structures on both sides, making full use of the space beneath the bridge frame for material handling without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

[0003] There are many bridge cranes on the market, such as the single-girder bridge crane with an off-center trolley disclosed in Chinese patent CN214653121U, the double-girder bridge crane for metallurgy disclosed in Chinese patent CN214141300U, and the bridge crane disclosed in Chinese patent CN223060552U. Most of these bridge cranes include a bridge frame and a lifting trolley. The lifting trolley is connected to the lifting device to move the heavy object. However, steel pipe storage and transfer vehicles usually travel in a simple straight line. The conventional way of moving heavy objects by bridge frame and lifting trolley of bridge cranes is too complicated for the entry and exit of steel pipe storage and transfer. These lifting devices are also not suitable for steel pipes. Moreover, the simple wire rope connection of the lifting device for lifting is prone to swaying during the movement.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a fully automatic steel pipe handling crane.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fully automatic steel pipe handling crane includes a bridge frame, end beams at both ends of the bridge frame, a lifting mechanism on the upper side of the bridge frame, and a steel pipe lifting device connected to the lifting mechanism. Wheels are provided on the lower side of each end beam, and one set of wheels is connected to a trolley traveling mechanism. The steel pipe lifting device includes a lifting beam and several sets of [-shaped] hooks arranged sequentially on the lifting beam, with each set of [-shaped] hooks parallel to each other. Two sets of lifting movable pulleys are provided on the upper side of the lifting beam. Guide fixed pulleys and wire rope fixing seats are respectively located on both sides of the lifting mechanism. The wire rope led out by the lifting mechanism passes sequentially through the guide fixed pulleys and the lifting movable pulleys and connects to the wire rope fixing seats. The lower side of the bridge frame and the upper side of the lifting beam are connected by two sets of symmetrical scissor arms. Each set includes at least two scissor arms. The uppermost scissor arm is hinged to the lower side of the bridge frame, and the lowermost scissor arm is hinged to the upper side of the lifting beam. Adjacent scissor arms are hinged to each other.

[0007] The cable tray includes two parallel main beams, with end beams connected to both ends of the main beams. The two main beams are connected in the middle by five sets of connecting seats, with gaps between each set of connecting seats. The lifting mechanism, guide pulley, and wire rope fixing seat are respectively set on the upper side of the connecting seats.

[0008] Vertical baffles are installed at both ends of the end beam, and connecting plates are installed on both sides of the vertical baffles. Horizontal mounting plates are installed at the bottom of the two connecting plates, and two sets of horizontal wheels are installed on the horizontal mounting plates. Vertical mounting plates are installed at the top of the two connecting plates, and buffers are installed on the vertical mounting plates.

[0009] A walkway is provided on the outside of the main beam, and guardrails are installed along the edge of the walkway.

[0010] Two sets of first supports are provided on the lower side of the main beam corresponding to the scissor arms, and a second support is provided on the upper side of the lifting beam corresponding to the first supports. The uppermost scissor arm is hinged to the first support, and the lowermost scissor arm is hinged to the second support.

[0011] The lifting beam is connected to a longitudinal support beam, which is aligned with the top of the hook. A second support is provided on the upper side of the longitudinal support beam.

[0012] The second support is located between the two lifting pulleys.

[0013] Each scissor arm includes two symmetrical hinged connecting plates, which are connected by a longitudinal connecting plate. When the scissor arm is closed, the lifting pulley is located in the gap between the two hinged connecting plates of the scissor arm.

[0014] The guide pulley includes a first pulley seat and a guide wheel rotatably connected to the first pulley seat. A pulley shield is provided on the top of the first pulley seat, and openings are provided on both sides of the first pulley seat to facilitate the entry and exit of the wire rope.

[0015] The lifting pulley includes a second pulley seat and a guide wheel rotatably connected to the second pulley seat. The top and both sides of the first pulley seat are open.

[0016] Compared to existing technologies, the advantages of this utility model are as follows: This utility model provides a fully automatic steel pipe handling crane suitable for use in conjunction with steel pipe storage transfer vehicles to transfer steel pipes. In specific use, steel pipes are moved from one transfer vehicle to another using a steel pipe lifting device. Since the transfer only occurs between transfer vehicles on different tracks, the lifting mechanism can be directly fixed to the bridge frame, eliminating the need for a lifting trolley. In addition, a scissor arm structure is provided to prevent the lifting device from swaying during the lifting process, fully ensuring the stability of the lifting process.
