Technical Field

[0001] This utility model relates to the field of cranes, and in particular to a bridge crane with self-locking anti-slip function. Background Technology

[0002] Current Status of Bridge Crane Technology: As a core piece of equipment in modern industrial material handling, bridge cranes generally employ an electric hoist combined with a bridge frame structure. The crane hook, as a key component directly bearing heavy loads, directly impacts the reliability of lifting operations due to its structural safety. Currently, standard hooks commonly use a C-shaped opening design, which, while convenient for attaching lifting devices, presents significant safety hazards. Most hooks on the market use manual locking mechanisms, which have clear limitations in practical applications. Manual locking devices require frequent operator intervention, increasing labor intensity and potentially leading to safety hazards in emergencies due to delayed human intervention.

A spring is provided between the bottom of the reset shaft and the reset cavity, and the other end of the reset shaft is connected to the plate of the pressing block. Beneficial effects

[0009] This utility model of a bridge crane with self-locking anti-slip design has the following advantages compared with the prior art:

[0010] This invention utilizes the weight of an object to press down on the pressing block, causing the L-shaped connecting block of the pressing block to rotate the self-locking shaft. This causes the self-locking shaft to move in the direction of the engagement shaft and engage with the notch of the engagement shaft, thus achieving a self-locking function and preventing the object from falling off. After the object is placed down, the pressing block is no longer pressed down by gravity, and it resets and pushes down again, causing it to rotate the self-locking shaft and open the opening of the hook body. This achieves a self-locking and self-opening effect, reducing frequent intervention by operators and lowering labor intensity.

[0011] This utility model allows for the installation of self-locking structures on both sides of the hook body, providing double insurance and increasing the safety protection factor during hook operation. This prevents items from sliding and falling during crane operation. The self-locking structure is detachable, allowing for direct removal and replacement when it becomes worn.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the preferred embodiments of this utility model are further described below in conjunction with specific implementation methods and accompanying drawings.

[0021] Example 1

[0022] Please see Figures 1-6 A bridge crane with self-locking anti-slip design includes a bridge frame 1, a slide rail 2, a traction line 3, a hook 4, and a mobile traction machine 5. The mobile traction machine 5 and the slide rail 2, which is integrally formed with the bridge frame 1, are slidably connected. The traction line 3 is embedded in the mobile traction machine 5 and connected to the hook 4. The hook 4 has a pulley 41 that cooperates with the traction line 3. The self-locking device 42 of the hook 4 is engaged with the surface of the hook body 45. The hook body 45 is threaded with a locking shaft 44. One end of the hook body 45 is installed inside the mounting box 43. T-shaped protrusions are provided on both sides of the hook body 45. The back of the self-locking device 42 has a groove corresponding to its shape.

[0023] The self-locking device 42 is provided with a self-locking shaft 421, a reset body 422, a pressing cavity 423, and a pressing block 424. The self-locking shaft 421 is movably connected to the pressing cavity 423 via a movable shaft. The pressing cavity 423 is provided with a reset body 422 on both sides. The top of the reset body 422 is connected to the pressing block 424. The pressing block 424 has an L-shaped connecting block on the outward side plate. The L-shaped connecting block is movably connected to the self-locking shaft 421 and the pressing block 424 via a movable shaft.

[0024] Both the pressing cavity 423 and the pressing block 424 are hollow structures. Both the pressing cavity 423 and the pressing block 424 have notches on the side that contacts the self-locking shaft 421. The pressing block 424 protrudes from the hook body 45 and the surface of the pressing block 424 is covered with a rubber layer.

[0025] Both the self-locking shaft 421 and the locking shaft 44 are arc-shaped structures. The self-locking shaft 421 is located between the pressing cavity 423 and the hollow cavity of the pressing block 424 via a movable shaft.

[0026] The hook body 45 is connected to the locking shaft 44 with a protruding threaded shaft at the end. The locking shaft 44 is provided with a threaded groove and a notch at one end. The diameter of the notch of the locking shaft 44 matches that of the self-locking shaft 421.

[0027] The reset body 422 consists of a reset cavity and a reset shaft. The reset shaft is fitted into the reset cavity. A spring is provided between the bottom of the reset shaft of the reset body 422 and the reset cavity. The other end of the reset shaft of the reset body 422 is connected to the plate of the pressing block 424.

[0028] Instructions for use: During the casting process, T-shaped protrusions and threaded shafts can be installed on both sides of the hook body 45. In use, the locking shaft 44 is threadedly connected to the hook body 45. The groove on the back of the self-locking device 42 engages with the T-shaped protrusions of the hook body 45, completing the self-locking structure assembly. If the self-locking device 42 or the locking shaft 44 is damaged, it can be replaced at any time. In use, the power is turned on, and the moving traction machine 5 moves on the slide rail 2. With the assistance of the moving traction machine 5, the traction line 3 extends the hook body 45 to hook the object's hanging rope. When the net is pulled, the weight of the object presses down on the pressing block 424, causing the pressing block 424 to press down into the pressing cavity 423. The L-shaped connecting block on the pressing block 424 pulls the self-locking shaft 421. Rotating, the self-locking shaft 421 moves towards the engaging shaft 44 and engages into the notch of the engaging shaft 44, realizing the self-locking function and preventing the object from falling off. The rubber layer on the pressing block 424 can increase the friction between the object hanging rope and the hook body 45. When the crane lifts the object to the designated position, the object is put down. At this time, the pressing block 424 is no longer pressed by gravity. The spring between the reset cavity and the reset shaft drives the reset shaft to move outward in the reset cavity, pushing the pressing block 424. The L-shaped connecting block of the pressing block 424 pulls the self-locking shaft 421 to rotate again, causing the self-locking shaft 421 to leave the engaging shaft 44 and open the opening of the hook body 45. The length of the self-locking structure can be set according to the needs to make it fit the hook body 45.
