Description

Technical Field

[0001] The utility model relates to the technical field of cranes, and more specifically, to an anti-skid self-locking electric single-beam bridge crane. Background Art

[0002] In the existing technology, the design of anti-skid self-locking electric single-beam bridge crane generally has some limitations and shortcomings, especially in the connection structure between the hook and the electric hoist. Usually, the connection between the hook and the electric hoist is fixed. Although this fixed connection structure provides a certain stability, it limits the flexible replacement of the hook. When it is necessary to handle goods of different shapes or special requirements, the operator usually needs to use cables to bind the goods and then lift the cables. This method not only increases the complexity of the operation, but also brings certain safety risks. For example, loose binding of the goods may cause accidental falling or slipping.

[0003] Although there are cranes with replaceable hooks on the market, these designs usually rely on multiple bolts to fix the hooks. This bolt-dependent installation method makes hook replacement complicated and laborious. Especially when the hook needs to be replaced quickly in an emergency, the complex bolt fixing method greatly prolongs the replacement time and affects work efficiency. In addition, the complex fixing method may also lead to operational errors and increase the labor intensity of the staff, thus affecting the overall operational safety and efficiency;

[0004] Another significant shortcoming in current technology is that the height of the crane's main beam cannot be adjusted. The fixed height of the main beam limits the applicability and flexibility of the crane in different operating environments. For example, when operating in a workshop with a low ceiling or in a confined space, the non-adjustable main beam may not be able to perform effective lifting operations, or lack flexibility when adapting to operating scenarios with different height requirements. Therefore, developing a crane with an adjustable main beam height can not only improve the adaptability of the equipment, but also meet the needs of a wider range of industrial applications, thereby improving work efficiency and safety.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides an anti-skid self-locking electric single-beam bridge crane, which has the following beneficial effects:

[0016] 1. The lifting mechanism includes a sliding seat, an electric hoist, a connector, a hook and a plug rod. This combination makes the entire equipment highly efficient and flexible in operation when handling and lifting goods. The electric hoist is installed on the sliding seat and can move laterally along the main beam.

The design of this mechanism greatly improves the convenience and safety of hook replacement. By pushing the control sleeve, the sliding sleeve slides along the slide rod to achieve quick release and locking of the clamping block. This quick replacement function enables the hook to adapt to goods of different shapes and weights and meet changing work requirements. The setting of the compression spring ensures automatic locking and release during the replacement process, improving the convenience and efficiency of operation.

[0018] 3. The lifting mechanism includes a lifting tube, a lifting rod, a hydraulic cylinder, a fixing hole and a fixing bolt. This design allows the height of the main beam to be adjusted according to different working environments and needs. By starting the hydraulic cylinder, the lifting rod pushes the main beam up or down to reach the ideal working height. The combination of the fixing holes and the fixing bolts can lock the main beam at any height, which not only improves the applicability of the equipment, but also enhances the safety during operation. Through this adjustable height function, the crane can more flexibly adapt to various different construction environments and work scenarios, thereby improving work efficiency.

[0034] In this embodiment, the cargo is connected to the hook 5, and then the electric hoist 3 is operated to lift the cargo on the hook 5, and then the sliding seat 2 is operated to slide along the main beam 1 to drive the cargo to move. When the hook 5 needs to be disassembled and replaced, the two groups of control sleeves 13 are pushed to both sides respectively, and the two groups of sliding sleeves 10 are driven by the control sleeves 13 to slide along the slide rod 11 to both ends respectively. At this time, the multiple groups of clamping blocks 9 are elastically pushed by the push springs 16 to slide outward along the clamping sleeves 8, so that the bottom ends are separated from the clamping grooves 15, and the clamping of the clamping rod 7 can be released, and then the plug rod 6 is pulled out of the socket 14, and then the hook 5 can be replaced with other styles of hooks 5. Finally, align the hook 5 with the socket 14 on the connecting piece 4, insert the insertion rod 6 into the socket 14, then align the sliding bar 17 on the clamping rod 7 with the sliding groove 18 set on the clamping sleeve 8, pull the control sleeve 13 to make the sliding sleeve 10 disengage from the clamping block 9, and at the same time, the sliding sleeve 10 squeezes the compression spring 12, and then insert the clamping rod 7 into the clamping sleeve 8, and then release the control sleeve 13, and push the sliding sleeve 10 through the compression spring 12 to reset, so that the inclined surface on the sliding sleeve 10 presses the top of the clamping block 9 downward, so that the bottom end of the clamping block 9 is clamped in the clamping groove 15 set on the clamping rod 7, and then the insertion rod 6 can be fixed to complete the replacement of the hook 5.
