Description

Technical Field

[0001] This invention relates to the field of overhead crane hoist technology, specifically to a multi-capacity combination overhead crane hoist. Background Technology

[0002] An electric hoist crane is a type of lifting machinery, a machine that performs cyclical, intermittent movements. One work cycle includes: the lifting device raising an item from its location, moving it horizontally to a designated location and lowering it, then reversing the movement to return the lifting device to its original position for the next cycle. Electric hoist cranes are mainly classified into single-girder cranes, single-girder overhead cranes, double-girder cranes, wall-mounted cranes, jib cranes, gantry cranes, and manual gantry cranes.

[0003] Electric hoist single-girder cranes utilize electric hoists, end beams, trolleys and carriages, drive electrical and control equipment, and can operate in rectangular areas and above them. They are mostly used for loading and unloading goods in workshops, warehouses, open-air storage yards, etc., and include beam cranes, bridge cranes, gantry cranes, cable cranes, transport bridges, etc.

[0004] The current industry standard solution is to configure two independent overhead cranes with different load capacities: one designed for low loads, focusing on high-speed performance; and the other designed for high loads, emphasizing load-bearing stability. However, this solution has significant drawbacks: on the one hand, the purchase cost, daily maintenance costs, and energy consumption costs of dual equipment are all significantly increased, which will significantly increase the company's operating costs in the long run; on the other hand, the two independent devices require their own independent installation space and running tracks, which not only occupies a large amount of usable space in the factory or work area, reducing site utilization, but may also interfere with the continuity of other work processes due to equipment layout issues, and even increase operational complexity and safety hazards when switching between them.

[0005] This situation, where dual equipment is forced to be used due to the large load range, has become a common problem restricting the improvement of lifting operation efficiency, cost optimization and space utilization. In the current pursuit of lean production and efficient operation, the need for better technical solutions to overcome this problem is becoming increasingly urgent. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] 1. Technical problems to be solved:

[0008] To address the issue of requiring high lifting speeds under low load conditions when the load range is large, the common practice is to use two independent overhead hoists with different capacities, which is costly and space-consuming. This invention is proposed to address this problem.

[0009] Therefore, the purpose of this invention is to provide a multi-capacity combined overhead crane hoist. This invention designs a multi-capacity combined electric overhead crane hoist where two hoists share a single trolley. The two hoists have different lifting capacities and speeds. The hoist includes a drive trolley, an auxiliary trolley, a connecting frame, a high-capacity hoist, and a low-capacity hoist, among other main components. Through the integrated electric drive trolley and connecting frame, the high-capacity and low-capacity hoists can operate under a single trolley, reducing the need for lifting beams, saving costs, and reducing space requirements. A wired remote control device is included, allowing for easy switching between different hoists to lift objects and to move along the track beam.

[0030] This invention provides a schematic diagram of the overall structure of one embodiment of a multi-capacity combined overhead hoist, comprising:

[0031] Please see Figures 1-2 This embodiment of a multi-capacity combination overhead crane includes a traveling rail 1, with a rack 2 parallel to the bottom of the traveling rail 1. A driving crane 3 and an auxiliary crane 4 are connected to the traveling rail 1. A connecting frame 5 is provided at the bottom of the driving crane 3 and the auxiliary crane 4. Hoist 1 6 and Hoist 2 7 are provided at the bottom of the connecting frame 5. Hoist 1 6 and Hoist 2 7 have different lifting speeds and lifting capacities. An electrical control box 8 is provided on the side wall of the connecting frame 5.

[0032] It is worth noting that, in order to facilitate the movement of the driving trolley 3, the top of the traveling track 1 is reserved with fixing bolts. The lateral synchronous track of the traveling track 1 is equipped with multiple sets of sliders. Wires are hung below the multiple sets of sliders. One end of the wires is connected to the electrical control box, which supplies power to the driving trolley and hoists 1 and 2. The other end of the wires is connected to the junction box 10.

[0033] Next, in order to facilitate the control of the electrical control box 8, a flip cover is connected to the side wall of the electrical control box 8 by a hinge, and a button controller 9 is connected to the bottom of the electrical control box 8 by wires.

[0034] Meanwhile, in order to facilitate the movement of the drive carriage 3, the top of the drive carriage 3 is driven by a motor to mesh with the bottom of the rack 2; the upper part of the drive carriage 3 is equipped with rollers, which travel on the upper surface of the bottom of the track and play a guiding role.

[0035] Furthermore, in order to ensure the normal use of gourd 16 and gourd 27, the tops of gourd 16 and gourd 27 are fixedly connected to the connecting frame 5 by bolts, and the bottoms of gourd 16 and gourd 27 are each independently equipped with hooks.

[0036] In addition, to ensure the limit is maintained and prevent the drive trolley 3 from disengaging from the rack 2, limit blocks are installed at both ends of the bottom of the travel track 1, with the installation positions of the limit blocks aligned with the installation positions of the rack 2. Simultaneously, limit switches are designed on both sides of the drive trolley 3 and the auxiliary trolley 4; when the limit switch contacts the limit block, it will trigger the trolley to stop.
