Abstract
Description
Technical Field
[0001] This utility model relates to the field of material transportation technology, and in particular to a hoisting device for material transportation. Background Technology
[0002] Gantry cranes, also known as portal cranes, are a type of bridge crane. Their metal structure resembles a portal frame, with two legs mounted under the main beam, allowing them to travel directly on ground-level tracks. The main beam can have cantilever beams extending outwards at both ends. The structure of a gantry crane is relatively simple, mainly consisting of a gantry frame, tracks, a crane itself, and an electrical control system. This structure gives gantry cranes high stability and wind resistance, enabling them to adapt to various complex environments. Furthermore, they can be controlled via remote control or a control room, facilitating various lifting tasks for operators. Therefore, small gantry cranes are often used in production workshops to quickly transfer materials between assembly lines, replacing manual handling and improving production efficiency. However, in existing gantry cranes, the hooks used to suspend heavy objects require manual opening and hanging each time, consuming operator time and energy and affecting efficiency.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0035] Example 1
[0036] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a hoisting device for material transportation. The hoisting device for material transportation includes a main body mechanism 1, an electric mechanism 2, and a hook mechanism 3. Through the specially designed hook mechanism 3 and the cooperation of each mechanism, the hook mechanism 3 can automatically hook and lift heavy objects during use.
[0037] The main structure 1 serves as the basic support, including a gantry column 11. One end of the gantry column 11 is fixedly connected to an I-beam 12, which can withstand a large load and provide an installation platform for other components. A triangular frame 13 is installed on the top of the gantry column 11 to enhance the overall stability and ensure the safety of hoisting by utilizing the stability characteristics of a triangle.
[0038] The electric mechanism 2 includes an electric hoist 21 installed on one side of the I-beam 12. The electric hoist 21 drives the rope 22 to extend and retract through an internal motor, and controls the lifting and unloading of the sinker plate 23 to realize the lifting and unloading of heavy objects. The electric hoist 21 is equipped with a rope 22, and the end of the rope 22 is fixedly connected to the sinker plate 23. The sinker plate 23 has a certain counterweight so that it can be squeezed by its gravity in the future.
[0039] The hook mechanism 3 includes a limiting post 31 disposed on one side of the pendant plate 23. A limiting hole 31-1 is provided inside the limiting post 31. The limiting hole 31-1 provides installation and movement space for the hook component 32. The hook component 32 is rotatably connected inside the limiting hole 31-1. The hook component 32 can rotate within the limiting hole 31-1 to complete the hook opening and closing action.
[0040] Example 2
[0041] Reference Figures 2 to 12 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0042] A suspension component 24 is fixedly connected to one side of the electric hoist 21, including a connecting block 24-1 fixedly connected to one side of the electric hoist 21. The connecting block 24-1 connects the electric hoist 21 to the protective disc 24-2. The protective disc 24-2 protects the electric hoist 21 from collision and wear during operation. The protective disc 24-2 is fixedly connected to one side of the connecting block 24-1. A rolling wheel 24-3 is rotatably connected to one side of the protective disc 24-2 and cooperates with the I-beam 12 to enable the electric hoist 21 to move smoothly laterally along the I-beam 12, which facilitates the hoisting of heavy objects in different positions and improves the flexibility of the hoisting device. The electric hoist 21 is existing technology, and its driving and hoisting technology is relatively mature, so it will not be described in detail here.
[0043] The pendant plate 23 has symmetrical sliding pieces 33 on both sides. The sliding pieces 33 are arranged in a Z-shape and their height is higher than that of the hook 32. This special shape design gives it a specific movement trajectory and function. When the hook 32 moves downward, the sliding pieces 33 will contact the weight first because their height is higher than that of the hook 32. A sliding groove 33-1 is opened on one side of the sliding piece 33. The sliding groove 33-1 on one side of the sliding piece 33 cooperates with the sliding block 25 fixed on one side of the pendant plate 23. The sliding block 25 slides in the sliding groove 33-1, causing relative movement between the pendant plate 23 and the sliding piece 33, thereby triggering the automatic hooking action of the hook mechanism 3.
[0044] A sliding block 25 is fixedly connected to one side of the pendant plate 23 and cooperates with the sliding groove 33-1. A pressing block 26 is fixedly connected to the bottom of the pendant plate 23. The pressing block 26 fixed at the bottom of the pendant plate 23 contacts the heavy object during hoisting. The force generated by the pressing pushes the hook 32 to complete the unlocking operation. It is an important power transmission component in the automatic hooking process. In use, the pendant plate 23 moves downward. When the sliding plate 33 contacts the heavy object first, the heavy object provides support for the sliding plate 33. Relying on this support, the sliding block 25 moves under the limitation of the sliding groove 33-1. At this time, due to the gravity of the pendant plate 23, the pressing block 26 at its bottom will press the hook 32 inside the limiting column 31, thereby realizing the automatic opening of the hook 32. This eliminates the need for the operator to manually open the hook 32 each time.
[0045] A spring component 34 is provided inside the limiting hole 31-1, including a triangular block 34-1 fixedly connected to one side of the inner wall of the limiting hole 31-1. A first spring 34-2 is fixedly connected to one side of the inclined surface of the triangular block 34-1. The first spring 34-2 connected to the inclined surface of the triangular block 34-1 is compressed when subjected to force, providing elastic force for the movement of the hook component 32, and assisting in the automatic opening and closing of the hook. In the default state without force, the second clamp 32-4 is pushed by the elastic force of the first spring 34-2, so that the hook component 32 is in the closed state in the default state. The hook component 32 will only be in the open state when the weight of the pendant plate 23 is squeezed.
[0046] The hook component 32 includes a rotating column 32-1 fixedly connected to one side of the inner wall of the limiting hole 31-1, which provides rotational support for the first clamp 32-2 and the second clamp 32-4. The first clamp 32-2 is rotatably connected to one side of the rotating column 32-1. The first clamp 32-2 has a rotating groove 32-3 inside. The rotating groove 32-3 provides space and guidance for the rotation of the first clamp 32-2 relative to the second clamp 32-4, ensuring accurate clamping action. The second clamp 32-4 is rotatably connected to one side of the rotating column 32-1. The second clamp 32-4 and the first clamp 32-2 cooperate with each other to complete the lifting of heavy objects.
[0047] The second clamp 32-4 has a spring groove 32-5 on one side, which cooperates with the first spring 34-2. One end of the first spring 34-2 is fixedly connected to the inclined side of the triangular block 34-1, and the other end is fixedly connected to the inner wall of the spring groove 32-5. When the first spring 34-2 is deformed by force, the elastic force generated pushes the second clamp 32-4 to rotate, so that it and the first clamp 32-2 together complete the clamping action of the weight hook 42, realizing the key link of automatic hooking.
[0048] A safety element 35 is provided on one side of the first clamp 32-2, including a first fixing block 35-1 fixedly connected to one side of the first clamp 32-2, and a second fixing block 35-2 fixedly connected to one side of the second clamp 32-4. Both the first fixing block 35-1 and the second fixing block 35-2 have circular holes 35-3 inside. A pin 35-4 is slidably disposed inside the circular hole 35-3. A second spring 35-5 is fixedly connected to one end of the pin 35-4. One end of the second spring 35-5 is fixedly connected to one side of the second fixing block 35-2. The first fixing block 35-1 and the second fixing block 35-2... 2 are respectively fixed to one side of the first clamp 32-2 and the second clamp 32-4. The internal circular hole 35-3 of the two clamps is used for the sliding of the pin 35-4. When the first clamp 32-2 and the second clamp 32-4 clamp the hook 42 of the heavy object, the pin 35-4 is inserted into the circular hole 35-3 under the action of the second spring 35-5. At this time, since the movement trajectory of the first clamp 32-2 and the second clamp 32-4 is inclined upward, and under the lateral limiting force of the pin 35-4, the first clamp 32-2 and the second clamp 32-4 are locked to prevent the hook from opening accidentally during hoisting and to ensure hoisting safety.
[0049] A rotating component 36 is provided on one side of the second clamp 32-4, including a square block 36-1 fixedly connected to one side of the second clamp 32-4. A rotating block 36-2 is rotatably connected to one side of the square block 36-1. A brake groove 35-6 is provided at the end of the pin post 35-4 and cooperates with the rotating block 36-2. When it is necessary to open the hook, pull the pin post 35-4 and operate the rotating block 36-2 to rotate and engage with the brake groove 35-6, thereby releasing the lock on the first clamp 32-2 and the second clamp 32-4, which facilitates the unloading of heavy objects.
[0050] The main body 1 has a heavy object 4 at its bottom, including a heavy object body 41 at the bottom of the main body 1. A hook 42 is fixedly connected to the top of the heavy object body 41. The heavy object body 41 is an object that needs to be hoisted and transported. The hook 42 fixed at its top cooperates with the hook part 32 of the hook mechanism 3 to realize the hoisting of the heavy object body 41.
[0051] When using it, first move the hoisting device to a suitable position above the heavy object, and then use the rolling wheel 24-3 of the suspension part 24 on one side of the electric hoist 21 to slide on the I-beam 12 to adjust the lateral position of the electric hoist 21.
[0052] In the initial state, the rotating block 36-2 engages with the brake groove 35-6, preventing the pin 35-4 from being inserted into the circular hole 35-3 of the first fixing block 35-1 and the second fixing block 35-2. The operator can rotate the rotating block 36-2 to release the restriction on the pin 35-4, allowing the pin 35-4 to be inserted into the circular hole 35-3 of the first fixing block 35-1 and the second fixing block 35-2, thus completing the locking operation between the first clamp 32-2 and the second clamp 32-4 and ensuring the hook is stable when lifting heavy objects. The operator can also pull the pin 35-4 to the rotating block 36-2, while simultaneously rotating the block 36-2, which, in conjunction with the brake groove 35-6, unlocks the first clamp 32-2 and the second clamp 32-4.
[0053] Next, the hanging plate 23 is lowered via rope 22, bringing the hook mechanism 3 close to the hook 42 at the top of the main body 41 of the heavy object. The hanging plate 23 moves downward, and when the sliding plate 33 first contacts the heavy object, the heavy object provides support to the sliding plate 33. Under the action of this force, the sliding block 25 moves within the limitation of the sliding groove 33-1. At this time, due to the gravity of the hanging plate 23, the first clamp 32-2 and the second clamp 32-4 rotate around the rotating column 32-1, opening and locking the hook 42 of the heavy object. Subsequently, the electric hoist 21 works in the opposite direction, causing the hanging plate... 23. Move upward a certain distance. At this time, the squeezing force on the first clamp 32-2 and the second clamp 32-4 is released. Under the restoring force of the first spring 34-2, the second clamp 32-4 is pushed, so that the first clamp 32-2 and the second clamp 32-4 are closed. At this time, rotate the rotating block 36-2 to release the limit on the pin 35-4. The second spring 35-5 pushes the pin 35-4 to insert into the circular hole 35-3 of the first fixing block 35-1 and the second fixing block 35-2, locking the first clamp 32-2 and the second clamp 32-4.
[0054] After the hook is completed, the electric hoist 21 lifts the hanging plate 23 via the rope 22 to lift the heavy object for transportation. When the target position is reached and the heavy object needs to be unloaded, the rotating block 36-2 of the rotating component 36 is operated to make it rotate and engage with the brake groove 35-6 of the pin 35-4. Pulling the pin 35-4 releases the lock, releases the hook 42 of the heavy object, and completes the unloading.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
