Description
Technical Field
[0001] This utility model relates to the field of crane technology, specifically to a double-beam crane with telescopic lifting capability. Background Technology
[0002] Double-girder bridge cranes are available in three types of operator cabs: open, closed, and insulated. The operator cab platform entrance is available in three types: side, end, and top. H represents the added height of the trolley buffer. Double-girder bridge cranes are available in indoor and outdoor models. When ordering, the highest and lowest temperatures of the working environment and the type of power supply should be specified. Overload limiters, large-screen displays, and various protective devices have been added, further enhancing safety during use.
[0003] The lifting height of traditional double-girder cranes is usually determined during the design and manufacturing process, making it difficult to adjust during actual use. When encountering situations requiring the lifting of heavy objects at higher positions or switching between work surfaces at different heights, double-girder cranes with fixed lifting heights become inadequate. For example, in the construction of multi-story buildings, as the floors rise, traditional double-girder cranes may not be able to meet the needs of lifting to higher floors, requiring frequent equipment changes or the construction of temporary lifting facilities, which increases construction costs and complexity. Therefore, there is an urgent need for a double-girder crane with telescopic lifting capabilities to overcome these shortcomings. Utility Model Content
[0004] The purpose of this utility model is to provide a double-girder crane with telescopic lifting, which has the advantages of convenient telescopic lifting and stability, 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 telescopic lifting double-girder crane, comprising a double-girder crane assembly, a movable fixing assembly, a support connecting assembly, and a positioning stabilizing assembly. The movable fixing assemblies are all disposed on both sides of the bottom of the double-girder crane assembly. The support connecting assembly is disposed at the bottom of the movable fixing assembly. The positioning stabilizing assemblies are all disposed on both sides of the top of the support connecting assembly. The double-girder crane assembly includes a slide rail and a double-girder crane body. The movable fixing assembly includes a positioning seat, a motor, a first threaded rod, a moving rod, a fixed crossbar, a first slide groove, a cylinder, a first slider, and a locking rod. The support connecting assembly includes a first connecting base plate, a first mounting hole, a second connecting base plate, and a second mounting hole. The positioning stabilizing assembly includes a locking seat, a second slide groove, a second slider, a connecting rod, and a locking groove.
[0006] Furthermore, both sides of the bottom of the double-girder crane body are slidably connected to slide rails, a positioning seat is provided at the center of the bottom of the slide rail, a motor is provided at the bottom of the inner cavity of the positioning seat, and a first connecting base plate is fixedly installed at the bottom of the motor.
[0007] Furthermore, the inner cavity of the positioning seat is provided with a movable rod, and the interior of the movable rod is rotatably connected to a first threaded rod by a thread. The bottom of the first threaded rod is fixedly connected to the output shaft of the motor, and the top of the movable rod is fixedly connected to the bottom of the slide rail.
[0008] Furthermore, a fixed crossbar is fixedly installed on both sides of the positioning seat, and a first sliding groove is opened inside the fixed crossbar. A first slider is slidably connected inside the first sliding groove, and a locking rod is fixedly installed on the top of the first slider.
[0009] Furthermore, a cylinder is fixedly installed in the inner cavity of the first slide groove on the side relatively far from the first slider, and a card seat is fixedly installed on both sides of the top of the first connecting base plate. A second slide groove is opened on both sides of the inner cavity of the card seat, and a second slider is slidably connected inside the second slide groove.
[0010] Furthermore, a connecting rod is fixedly installed on the side of the second slider that is relatively close to it. The connecting rod has evenly distributed slots on the side that is relatively close to it, and the top of the connecting rod is fixedly connected to the bottom of the slide rail.
[0011] Furthermore, two second connecting base plates are fixedly installed on the relatively close side of the first connecting base plate. A second mounting hole is opened in the center of the interior of the second connecting base plate, and a first mounting hole is opened on both sides of the interior of the first connecting base plate. The bottom of the positioning seat is fixedly connected to the top of the first connecting base plate.
[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are: This utility model uses a double-girder crane assembly to lift heavy objects, a movable fixing assembly to move and fix the position of the double-girder crane assembly, a support connection assembly to increase the overall stability of the device, and a positioning stabilizing assembly to limit the movement of the double-girder crane assembly and prevent it from swaying during movement. During lifting, the motor is first turned on, driving the first threaded rod to rotate, causing the moving rod to move the slide rail and the main body of the double-girder crane upwards. Simultaneously, the main body of the double-girder crane moves the connecting rod upwards. After reaching the designated position, the cylinder is opened, driving the first slider to move outwards. The locking rod passes through the locking groove into the interior of the connecting rod, thus fixing the entire device. This design offers the advantages of convenient telescopic lifting and stable operation, solving the problem of difficulty in adjustment during actual use. When encountering situations requiring lifting heavy objects at higher positions or switching between work surfaces at different heights, double-girder cranes with fixed lifting heights are often inadequate. For example, in the construction of multi-story buildings, as the floors rise, traditional double-girder cranes may not be able to meet the needs of lifting to higher floors, requiring frequent equipment changes or the construction of temporary lifting facilities, increasing construction costs and complexity.
