Description

Technical Field

[0001] This utility model relates to the field of bridge crane technology, specifically to a bridge crane with anti-disengagement mechanism. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards to lift and transport materials. Because its two ends are supported by tall concrete pillars or metal supports, it resembles a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated structures on both sides, making full use of the space under the bridge frame to lift and transport materials without being obstructed by ground equipment. It is the most widely used and most numerous type of lifting machinery.

[0003] Some bridge cranes have poorly designed anti-detachment devices, which are not securely connected to the hook or cannot effectively prevent heavy objects from falling off the hook in complex operating environments. Some anti-detachment devices are prone to loosening or failure after frequent lifting and lowering operations, and cannot reliably play their anti-detachment role. Therefore, there is an urgent need for a bridge crane with anti-detachment hook to overcome the above defects. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge crane that prevents disengagement, which has the advantages of preventing disengagement and having a good fixed support effect, 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 bridge crane with anti-detachment hook, comprising an X-axis moving mechanism, a Y-axis moving mechanism, an electric hoist, a clamping and supporting bottom assembly, and an anti-detachment hook assembly. The Y-axis moving mechanism is fixedly installed on both sides of the bottom of the X-axis moving mechanism, the electric hoist is fixedly installed at the center of the bottom of the X-axis moving mechanism, the clamping and supporting bottom assembly is disposed on both sides of the electric hoist, and the anti-detachment hook assembly is disposed at the bottom of the electric hoist. The clamping and supporting bottom assembly includes a limiting frame, a turntable, a fixing rod, a sliding sleeve, a bottom supporting L-shaped plate, a connecting block, a sliding groove, a slider, and a threaded rod. The anti-detachment hook assembly includes a hook body, an iron sealing ring, a limiting groove, a limiting sliding rod, and a magnetic block.

[0006] Furthermore, the bottom of the electric hoist is movably connected to a hook body via a positioning pin, and iron sealing rings are provided on both sides of the hook body, while magnetic blocks are fixedly installed on both sides of the hook body.

[0007] Furthermore, a limiting groove is formed inside the iron sealing ring, and a limiting slide rod is slidably connected inside the limiting groove. The side of the limiting slide rod that is relatively close to the hook body is fixedly connected to both sides.

[0008] Furthermore, fixed rods are fixedly installed on both sides of the electric hoist, and a sliding groove is opened inside the fixed rod, with a slider slidably connected inside the sliding groove.

[0009] Furthermore, connecting blocks are fixedly installed on both the front and rear sides of the slider, and a sliding sleeve is fixedly installed on the side of the connecting block that is relatively far away from each other. A limit frame is slidably connected inside the sliding sleeve.

[0010] Furthermore, the limiting frame is fixedly connected to both sides of the fixing rod on the relatively close side, the sliding sleeve is fixedly installed with a bottom L-shaped plate on the relatively close side, and a turntable is provided on the outer side of the fixing rod.

[0011] Furthermore, the slider is internally connected to a threaded rod via a threaded connection, and the relatively distant side of the threaded rod extends through to the outside of the fixed rod and is fixedly connected to the inside of the turntable.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention utilizes a Y-axis moving mechanism to move the X-axis moving mechanism longitudinally, and the X-axis moving mechanism to move the electric hoist laterally. The electric hoist is used to raise and lower the clamping and supporting assembly and the anti-detachment hook assembly. The clamping and supporting assembly secures the goods on both sides to prevent them from falling off, and the anti-detachment hook assembly suspends the goods to prevent them from coming off the hook. In use, the goods are first suspended in the inner cavity of the hook body. Then, the iron sealing ring is rotated. After rotating to the designated position, the iron sealing ring is magnetically attracted by the magnetic block. After fixing, the turntable is rotated, which drives the threaded rod to rotate, causing the slider to move the connecting block and the sliding sleeve inward. Finally, under the action of the bottom L-shaped plate, the goods are supported and fixed. It has the advantages of preventing hook detachment and good bottom support effect. It solves the problems of some bridge cranes' anti-detachment devices being poorly designed, their connection with the hook is not stable enough, or in complex working environments, they cannot effectively prevent heavy objects from falling off the hook. Some anti-detachment devices are prone to loosening and failure after frequent lifting and lowering operations, and cannot continuously and reliably play the anti-detachment role.
