Description

Technical Field

[0001] This utility model relates to the field of bridge crane technology, and specifically to a bridge crane that is easy to move. 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, resembling a bridge, the bridge frame of a bridge crane runs longitudinally along rails laid on elevated structures on both sides. This allows for full utilization 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] While bridge cranes are relatively flexible and easy to move, it is inconvenient to lock and fix them in their original position after they are moved. This can cause displacement when lifting heavy loads, which increases the trouble for the lifting personnel and may also lead to lifting accidents. Therefore, there is an urgent need for a bridge crane that is easy to move to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge crane that is easy to move and has the advantages of being easy to move and preventing displacement, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveniently movable bridge crane, comprising a bridge crane assembly, an anti-displacement fixing assembly, a positioning friction assembly, and a snap-fit ​​fixing assembly. The anti-displacement fixing assemblies are all disposed on both sides of the top of the bridge crane assembly. The positioning friction assemblies are all disposed on both sides of the bridge crane assembly. The snap-fit ​​fixing assembly is disposed on the front of the bridge crane assembly. The bridge crane assembly includes a bridge frame body, a first traveling mechanism, a trolley bridge frame, an electric hoist, a second traveling mechanism, a first slide rail, a walkway, and a second slide rail. The anti-displacement fixing assembly includes a connecting rod, a mounting column, a positioning seat, a slot, a groove, a threaded rod, a slider, an L-shaped rod, and a drive motor. The positioning friction assembly includes a first cylinder and a fixed brake disc. The snap-fit ​​fixing assembly includes a positioning plate, a positioning column, a second cylinder, and a fixing groove.

[0006] Furthermore, the second slide rails are fixedly installed on both sides of the top of the cable tray body, the first transfer mechanism slides on the top of the second slide rails, the trolley cable tray is fixedly installed on the top of the first transfer mechanism, the electric hoist is fixedly installed on the top of the trolley cable tray, and the walkway is fixedly installed on the front of the cable tray body.

[0007] Furthermore, the second transfer mechanism is fixedly installed on both sides of the cable tray body. The bottom of the second transfer mechanism is slidably provided with a first slide rail. The top of the first slide rail is fixedly installed with a positioning seat. The outer side of the positioning seat is evenly provided with slots.

[0008] Furthermore, a first cylinder is fixedly installed at the center of both sides of the second transfer mechanism, a fixed brake disc is fixedly installed on the side of the first cylinder that is relatively far away from it, a mounting column is fixedly installed at the center of the top of the second transfer mechanism, and a connecting rod is fixedly installed on the side of the mounting column that is relatively far away from it.

[0009] Furthermore, a drive motor is fixedly installed on the side of the connecting rod that is relatively far away from the connecting rod, a sliding groove is opened inside the connecting rod, a slider is slidably connected inside the sliding groove, and an L-shaped rod is fixedly installed at the bottom of the slider.

[0010] Furthermore, the threaded rod rotates inside the slider via a thread, the output shaft of the drive motor passes through the inner cavity of the slide groove and is fixedly connected to the side of the threaded rod that is relatively far away from it, the positioning plate is fixedly installed on both sides of the front of the trolley bridge, and the second cylinder is fixedly installed on the top of the positioning plate.

[0011] Furthermore, the positioning post is located at the bottom of the positioning plate, the bottom of the second cylinder extends through to the bottom of the positioning plate and is fixedly connected to the top of the positioning post, and the fixing grooves are evenly opened on the top of the cable tray body.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This utility model uses a bridge crane assembly to transfer heavy loads. Anti-displacement fixing components and positioning friction components secure both sides of the bridge crane assembly, while a snap-fit ​​fixing component secures the front of the first transferring mechanism. In use, the bridge frame body is first moved to the designated position via the second transferring mechanism. Simultaneously, the first slide rail prevents the second transferring mechanism from swaying during movement. Then, the electric hoist is transferred to the designated position by the first transferring mechanism. After the second and first transferring mechanisms have finished moving, the drive motor, the first cylinder, and the second cylinder are activated. The second cylinder causes the positioning pin to pass through the fixing groove into the bridge frame. Inside the main body of the frame, the first moving mechanism is fixed, and the position of the electric hoist is fixed after the first moving mechanism is fixed. At the same time, the drive motor drives the threaded rod to rotate, so that the slider drives the L-shaped rod to move inward. The L-shaped rod passes through the slot into the interior of the positioning seat, thereby fixing the main body of the bridge frame and the second moving mechanism. Finally, the goods are hoisted by the electric hoist. It has the advantages of convenient movement and anti-displacement. It solves the problem that although the bridge crane is relatively flexible and convenient to move, it is not convenient to lock and fix its original position after moving. This can cause displacement when the load is heavy, which increases the trouble for the hoisting personnel and may also cause hoisting accidents. Attached Figure Description
