Description

Technical Field

[0001] This utility model relates to the field of electric hoist technology, specifically a novel electric hoist mounting structure. Background Technology

[0002] Electric hoists are specialized lifting devices installed on overhead cranes and gantry cranes. They are characterized by their small size, light weight, simple operation, and ease of use, making them suitable for industrial and mining enterprises, warehouses, docks, and other similar locations. Electric hoists have a compact structure, with the motor axis perpendicular to the drum axis, and employ a worm gear drive. Their disadvantages include large length and width dimensions, bulky structure, low mechanical efficiency, and difficulty in manufacturing. The hydraulic system features dual control; both the overflow regulating valve and the magnetic contact pressure gauge provide precise pressure control. The electrical control system utilizes low-voltage control, enhancing the safety of the control system.

[0003] However, when existing electric hoist hooks are used to lift materials, the hooks sway, which can easily cause the hooks to detach from the materials, resulting in the materials falling to the ground and creating a safety hazard. In order to address the above problems, the inventors have proposed a new type of electric hoist hook structure to solve the above problems. Utility Model Content

[0004] To address the problem that the hook of an electric hoist wobbles when lifting materials, easily causing the hook to detach from the material, the purpose of this utility model is to provide a novel electric hoist hook connection structure.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: A novel electric hoist hook structure includes an electric hoist body, a steel wire rope wound inside the electric hoist body, a horizontal plate fixed at the bottom end of the steel wire rope, a hook fixed at the top surface of the horizontal plate, a connecting plate above the horizontal plate, an inclined plate fixed at one side of the connecting plate, the inclined plate slidingly disposed on the top surface of the horizontal plate, a rod slidingly passing through the horizontal plate, the rod being movably inserted into the hook, a movable plate fixed at the top end of the rod, an ear plate fixed at the bottom surface of the movable plate, a roller rotating within the ear plate, the roller rolling on the top surface of the inclined plate, a slot opened in the hook, the rod being movably inserted into the slot, a fixed plate fixed at the top surface of the horizontal plate, a pull rod slidingly passing through the fixed plate, the pull rod being fixedly connected to one side of the connecting plate. Install the device in the designated position, then rotate the double-acting screw to move the two threaded blocks away from the two limiting plates and disengage them from the horizontal plate. This allows the horizontal plate to descend when the wire rope is unwound. By pushing the pull rod, the connecting plate slides the inclined plate onto the top surface of the horizontal plate, causing the roller to roll on the inclined surface. The inclined plate moves the slider within the groove, simultaneously compressing the spring and causing the roller to roll on the inclined surface, disengaging the insertion rod from the slot. This allows the moving plate to lift the insertion rod, facilitating the hook and material lifting. Releasing the pull rod resets the spring, resetting the slider and inclined plate, allowing the insertion rod to re-insert into the slot. The inclined plate then resets, causing the insertion rod to re-insert into the slot. This prevents the hook from detaching from the material during lifting, preventing the material from falling to the ground and reducing safety hazards.

[0006] When not in use, start the electric hoist body to cause the wire rope to wind up on the drum surface. When the horizontal plate rises to be flush with the limit plate, notify the electric hoist body to stop. By rotating the double-acting screw, the threaded blocks slide against each other in the fixed frame, thereby causing the two limit plates to move relative to each other and fit onto the outer surface of the horizontal plate, thus limiting the horizontal plate. This makes it easy to fix the hook when not in use, facilitating transportation.

[0007] Preferably, a slider is fixedly provided on the bottom surface of the inclined plate, the slider is slidably disposed in the horizontal plate, a groove is provided in the horizontal plate, the slider is slidably disposed in the groove, a spring is fixedly connected between the groove and the slider, a sliding rod is fixedly provided in the groove, and the slider is slidably sleeved on the outer surface of the sliding rod.

[0008] Preferably, a fixed frame is fixedly provided on one side of the electric hoist body, and threaded blocks are slidably provided in opposite directions within the fixed frame. A limiting plate is fixedly provided on the bottom surface of the threaded blocks, and a limiting groove is provided in the limiting plate. The horizontal plate is locked in the limiting groove. A bidirectional lead screw is rotatably provided within the fixed frame, and the threaded blocks are threaded onto the outer surface of the bidirectional lead screw.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, by disengaging the insert rod from the slot, it is easier to lift the hook and the material. Then, the insert rod is reinserted into the slot, which prevents the hook from falling off the material when lifting it, thus reducing the safety hazard.

[0011] 2. In this utility model, by rotating the bidirectional lead screw, the threaded blocks slide against each other within the fixed frame, thereby causing the two limiting plates to move relative to each other and fit onto the outer surface of the horizontal plate, thus limiting the horizontal plate. In the absence of use, the hook can be easily fixed, facilitating transportation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides a novel electric hoist hook structure, including an electric hoist body 1, a steel wire rope 11 wound inside the electric hoist body 1, a horizontal plate 2 fixedly mounted at the bottom end of the steel wire rope 11, a hook 21 fixedly mounted on the top surface of the horizontal plate 2, a connecting plate 26 above the horizontal plate 2, an inclined plate 24 fixedly mounted on one side of the connecting plate 26, the inclined plate 24 slidably mounted on the top surface of the horizontal plate 2, a rod 3 slidably passing through the horizontal plate 2, the rod 3 being movably inserted into the hook 21, and a movable plate 31 fixedly mounted at the top end of the rod 3. The bottom surface of the 31 is fixedly provided with an ear plate 32, and a roller 33 is rotatably provided in the ear plate 32. The roller 33 rolls on the top surface of the inclined plate 24. A slot 211 is opened in the hook 21, and the insertion rod 3 is movably inserted into the slot 211. A fixing plate 27 is fixedly provided on the top surface of the horizontal plate 2. A pull rod 28 slides through the fixing plate 27. The pull rod 28 is fixedly connected to one side of the connecting plate 26. The electric hoist body 1 includes a motor, a transmission mechanism, a drum, and a lifting motor. The drum is driven to rotate by the motor, thereby realizing the lifting and moving of heavy objects. The electric motor provides power, which is transmitted to the drum through the transmission mechanism. When the drum rotates, it winds or releases the wire rope 11, thereby lifting and lowering the heavy object. By pushing the pull rod 28, the connecting plate 26 causes the inclined plate 24 to slide on the top surface of the horizontal plate 2, which in turn causes the roller 33 to roll on the inclined surface of the inclined plate 24. This causes the moving plate 31 to lift the insertion rod 3, and at the same time, the insertion rod 3 disengages from the slot 211, which facilitates the hook 21 and the material to be lifted. Then, pulling the pull rod 28 resets the inclined plate 24, causing the insertion rod 3 to re-insert into the slot 211. This prevents the hook 21 from falling off the material when lifting it, and the material will not fall to the ground, reducing safety hazards.

[0021] A slider 25 is fixedly provided on the bottom surface of the inclined plate 24. The slider 25 is slidably disposed in the horizontal plate 2. A groove 201 is provided in the horizontal plate 2. The slider 25 is slidably disposed in the groove 201. A spring 23 is fixedly connected between the groove 201 and the slider 25. A sliding rod 22 is fixedly provided in the groove 201. The slider 25 is slidably sleeved on the outer surface of the sliding rod 22.

[0022] By adopting the above technical solution, when the pull rod 28 is pushed, the inclined plate 24 drives the slider 25 to slide in the groove 201, while squeezing the spring 23, which in turn causes the roller 33 to roll on the inclined surface of the inclined plate 24, causing the insertion rod 3 to disengage from the slot 211, so that the material can be hung on the hook 21. Then the pull rod 28 is released, which causes the spring 23 to return to its original position, which in turn causes the slider 25 and the inclined plate 24 to return to their original positions, allowing the insertion rod 3 to be inserted into the slot 211 again, and then the hook 21 is sealed after the material is hoisted.

[0023] A fixed frame 4 is fixedly provided on one side of the electric hoist body 1. Threaded blocks 42 are slidably provided in the fixed frame 4. A limiting plate 43 is fixedly provided on the bottom surface of the threaded blocks 42. A limiting groove 44 is opened in the limiting plate 43. A horizontal plate 2 is stuck in the limiting groove 44. A bidirectional lead screw 41 is rotatably provided in the fixed frame 4. The threaded blocks 42 are threadedly sleeved on the outer surface of the bidirectional lead screw 41.

[0024] By adopting the above technical solution, by rotating the bidirectional lead screw 41, the threaded blocks 42 slide relative to each other within the fixed frame 4, thereby causing the two limiting plates 43 to move relative to each other and fit onto the outer surface of the horizontal plate 2, thereby limiting the horizontal plate 2. In the absence of use, it is convenient to fix the hook 21 and facilitate its transportation.

[0025] Working principle: First, install the device in the designated position. Then, rotate the double-acting screw 41, causing the two threaded blocks 42 to move the two limiting plates 43 away from each other and disengage the two limiting plates 43 from the horizontal plate 2. When the wire rope 11 is unwound, the horizontal plate 2 can descend. By pushing the pull rod 28, the connecting plate 26 causes the inclined plate 24 to slide on the top surface of the horizontal plate 2, thereby causing the roller 33 to roll on the inclined surface of the inclined plate 24. The inclined plate 24 causes the slider 25 to slide within the groove 201, simultaneously compressing the spring 23, thus causing the roller 33 to roll on the inclined surface. On the inclined surface of plate 24, the insertion rod 3 is disengaged from the slot 211, which in turn causes the moving plate 31 to lift the insertion rod 3. At the same time, the insertion rod 3 is disengaged from the slot 211, which facilitates the lifting of the hook 21 and the material. The pull rod 28 is released, which causes the spring 23 to return to its original position, which in turn causes the slider 25 and the inclined plate 24 to return to their original positions, allowing the insertion rod 3 to be inserted back into the slot 211. This causes the inclined plate 24 to return to its original position, prompting the insertion rod 3 to be inserted back into the slot 211. This prevents the hook 21 from falling off the material when lifting it, and the material will not fall to the ground, reducing safety hazards.

[0026] When not in use, start the electric hoist body 1 to cause the wire rope 11 to be wound on the drum surface. When the horizontal plate 2 rises to be flush with the limit plate 43, notify the electric hoist body 1 to stop. By rotating the double-acting screw 41, the threaded blocks 42 slide against each other in the fixed frame 4, thereby causing the two limit plates 43 to move relative to each other and fit on the outer surface of the horizontal plate 2, thus limiting the horizontal plate 2. In the absence of use, it is convenient to fix the hook 21 and facilitate its transportation.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
