Description

Technical Field

[0001] This utility model relates to the field of crane auxiliary accessories technology, and in particular to a safety locking component for cranes. Background Technology

[0002] Gantry cranes, also known as overhead cranes or bridge cranes, can be classified into various types based on their structural form and application, such as single-girder gantry cranes, double-girder gantry cranes, and semi-gantry cranes. This type of crane is typically used for loading and unloading heavy or large goods such as containers, steel, timber, and machinery, and is an indispensable piece of equipment in modern logistics and industrial production.

[0003] Regarding the aforementioned technologies, it has been found that existing cranes suspend items by using a hook to suspend them via a steel wire. During the suspension process, the rope wheel on the hook moves along the suspension steel wire, and there is no corresponding restraint structure during the movement. As a result, if the goods sway significantly, it is inconvenient to stabilize them in a timely manner, affecting the safety of the goods movement. Utility Model Content

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, a safety locking assembly for a crane includes a hook housing 1, which includes a middle shell 11 and a wheel housing 12. The wheel housing 12 is installed at both ends of the middle shell 11 and is fixedly connected to the middle shell 11. A double-headed frame 2 is fixedly installed in the middle of the middle shell 11. Suspension wheels 3 are installed at both ends of the double-headed frame 2 and are rotatably connected to the double-headed frame 2. The suspension wheels 3 are installed in the wheel housing 12. An additional frame seat 4 is fixedly installed below the wheel housing 12 at both ends. Locking brackets 5 are installed on both sides of the additional frame seat 4 and are slidably connected to the additional frame seat 4. A drive assembly 6 for driving the locking brackets 5 to rise and fall is also fixedly installed on the lower end face of the additional frame seat 4. By designing the hook housing 1 into a structure where the middle housing 11 and the wheel housing 12 cooperate, the double-head frame 2 is installed through the middle housing 11. Suspension wheels 3 are installed at both ends of the double-head frame 2 to facilitate the suspension and movement of the lifting rope, improving the crane's lifting flexibility. The suspension wheels 3 are placed within the wheel housing 12, ensuring their protection. A mounting frame 4 is fixedly installed below the wheel housing 12, facilitating the installation of the locking bracket 5. During use, the driving assembly 6 drives the locking bracket 5 to rise and fall, locking the lifting rope. This ensures locking onto the rope and effectively prevents slippage, significantly improving the crane's operational safety.

[0028] Reference Figure 2 and Figure 3 As shown, the middle shell 11 includes a tube shell portion 111, side plate portions 112, and a water platform 113. Two sets of side plate portions 112 are configured, and each set is fixedly installed on one side of the tube shell portion 111. The water platform 113 is fixedly installed between the two sets of side plate portions 112, and a double-headed hook 13 is rotatably mounted on the lower end of the water platform 113. The structural design of the middle shell 11 gives it good load-bearing capacity, enabling it to withstand large weights. The two sets of side plate portions 112 ensure the stable installation of the water platform 113, and the double-headed hook 13 can be rotatably mounted on the water platform 113 during use. The double-headed hook 13 allows for easy connection to different types of heavy objects, expanding the crane's applicability and improving its overall suitability. The sheave housing 12 includes an annular housing 121 and an outer baffle 122. The outer baffle 122 is installed on both sides of the annular housing 121 and is fixedly connected to the annular housing 121. Two sets of rope grooves 123 are also provided on the annular housing 121. The rope grooves 123 on the sheave housing 12 ensure that the rope passes stably through the suspension wheel 3 within the sheave housing 12 and also limit the movement of the rope, preventing it from swaying during lifting and ensuring lifting stability. The outer baffle 122 provides protection for the suspension wheel 3.

[0029] Reference Figure 4 and Figure 5As shown, the mounting frame 4 includes a main frame plate 41 and a guide frame 42 for sliding installation of the locking bracket 5. The guide frame 42 is symmetrically installed on the lower end face of the main frame plate 41, and the guide frame 42 and the main frame plate 41 are integrally formed. The integrally formed structure of the mounting frame 4 is more robust and durable, and can withstand greater external forces. In use, the main frame plate 41 can be directly fixedly installed on the lower end of the lifting wheel housing 12. The guide frame 42 provides precise guidance for the sliding of the locking bracket 5, ensuring the stability of the movement of the locking bracket 5, thereby improving the reliability of locking the lifting rope.

[0030] Reference Figure 4 and Figure 5 As shown, the locking bracket 5 includes a longitudinal sliding plate 51 and an arc-shaped clamping block 52. The longitudinal sliding plate 51 is slidably mounted in the guide frame 42, and the arc-shaped clamping block 52 is fixedly mounted on the head of the longitudinal sliding plate 51. The arc-shaped clamping block 52 of the locking bracket 5 is designed to better fit the suspension rope, increasing the contact area with the suspension rope, improving the locking effect of the suspension rope, and effectively preventing the suspension rope from loosening and slipping. A guide groove 511 is provided on the longitudinal sliding plate 51, and horizontal grooves 421 that cooperate with the guide groove 511 are formed on both sides of the guide frame 42. The cooperation of the guide groove 511 and the horizontal groove 421 cleverly converts the linear motion of the drive component 6 into the lifting motion of the locking bracket 5, realizing the locking and unlocking function of the suspension rope. The structure is simple and the transmission is reliable.

[0031] Reference Figure 6 As shown, the drive assembly 6 includes an outer slide block 61, a cylindrical rod 62, and an inner slider 63. The cylindrical rod 62 passes through the guide groove 511 and the horizontal groove 421. The outer slide block 61 and the inner slider 63 are fixedly installed at both ends of the cylindrical rod 62. An electric cylinder 411 for driving the movement of the outer slide block 61 is also fixedly installed on the lower end face of the main frame plate 41. The drive assembly 6 is driven by the electric cylinder 411, which is convenient to operate and can accurately control the lifting and lowering of the locking bracket 5. The cooperation of the outer slide block 61, the cylindrical rod 62, and the inner slider 63 ensures the stability and reliability of the driving process and improves the working efficiency of the entire safety locking assembly. At the same time, in actual use, a controller for controlling the movement of the electric cylinder 411 and a corresponding power supply device can be installed on the main frame plate 41, so that the drive assembly 6 can be used independently without an external power supply.

[0032] In this embodiment, when a heavy object needs to be lifted, the lifting rope is looped around the suspension wheel 3 and through the lifting rope groove 123, and then the double-headed hook 13 is connected to the heavy object. After starting the electric cylinder 411, the electric cylinder 411 can drive the outer slide block 61 to move. The outer slide block 61 drives the longitudinal slide plate 51 to slide in the guide frame 42 through the cylindrical rod 62. Due to the cooperation of the guide inclined groove 511 and the horizontal groove 421, the longitudinal slide plate 51 will drive the arc-shaped clamping block 52 to rise, thereby clamping the lifting rope and locking the lifting rope. This can quickly stabilize the goods. After the goods are stabilized, the electric cylinder 411 can be started to move in the opposite direction, causing the outer slide block 61 to drive the longitudinal slide plate 51 to fall, and the arc-shaped clamping block 52 to release the lifting rope and release the lock on the lifting rope. In this way, the goods can be moved.

[0033] The above are preferred embodiments of this utility model. Those skilled in the art to which this utility model pertains should not make changes or modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
