Description

Technical Field

[0001] This utility model belongs to the field of hoisting machine technology, and specifically relates to a hoisting machine with high stability. Background Technology

[0002] As an important type of mechanical equipment, hoisting machines are widely used in many fields such as construction, warehousing and logistics, and factory production due to their core functions of vertical lifting and horizontal transport of heavy objects. They mainly rely on power units, such as motors and hydraulic systems, to drive lifting devices, such as wire ropes, chains, and hooks, to achieve the lifting and movement of goods.

[0003] In actual material handling operations, taking a gantry crane as an example, the workflow is as follows: First, the motor drives the wire rope to be slowly lowered, and then the hook on the wire rope is connected to the goods. Afterward, the motor reverses, and the wire rope is gradually retracted. As the length of the wire rope decreases, the goods are slowly lifted. Subsequently, with the help of the casters on the gantry, the goods are horizontally transported.

[0004] However, a significant problem exists during this series of operations. When the gantry crane is moved, the cargo will sway due to the inertia generated by the movement, caused by the steel wire ropes. Once the cargo sways, its center of gravity will inevitably shift. This shift in the center of gravity severely compromises the overall stability of the hoist, posing a significant safety hazard to the hoisting operation. Moreover, the swaying of the cargo reduces the efficiency of the hoisting operation, increases the difficulty and risk of operation, and may even lead to damage to the cargo or cause safety accidents, causing numerous adverse effects on the normal conduct of hoisting work. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable hoisting machine, addressing the problem in existing technologies where, when the gantry crane is moved, the cargo sways via the wire rope due to the inertia generated during movement. Once the cargo sways, its center of gravity inevitably shifts. This shift severely compromises the overall stability of the hoisting machine, posing a significant safety hazard to hoisting operations. Furthermore, the swaying of the cargo reduces hoisting efficiency, increases operational difficulty and risk, and may even lead to cargo damage or safety accidents, causing numerous adverse effects on the normal operation of hoisting work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly stable hoisting machine, comprising a support base, two of which are symmetrically arranged. Universal rollers are installed at the bottom of each support base, and a rectangular support column is connected to the top of each support base. A crossbeam is connected to the top of each rectangular support column, and an electric hoist is fixedly connected to the surface of the crossbeam. A baffle is fixedly connected between the two rectangular support columns. A bidirectional threaded rod is rotatably connected to the inside of the baffle via a bearing. A guide rod is assembled inside the baffle. A threaded sleeve is threadedly connected to the surface of the bidirectional threaded rod, and a guide sleeve is fitted onto the surface of the guide rod. A clamping block is connected to the bottom of the threaded sleeve and the guide sleeve. A servo motor is connected to the side wall of each rectangular support column.

[0007] As a preferred embodiment of this utility model for a highly stable hoisting machine, the output shaft of the servo motor passes through a rectangular support column and is connected to a bidirectional threaded rod.

[0008] As a preferred embodiment of the hoisting machine with high stability according to this utility model, the clamping block can form a reciprocating threaded motion with the baffle through the threaded sleeve and the bidirectional threaded rod.

[0009] As a preferred embodiment of the present invention, which provides a highly stable hoisting machine, the clamping block can be slidably connected to the baffle via a guide sleeve and a guide rod.

[0010] As a preferred embodiment of the present invention, which provides a highly stable hoisting machine, the two clamping blocks are symmetrical about the center of the baffle.

[0011] As a preferred embodiment of the present invention, a hoisting machine with high stability is provided, wherein the bottom end of the support base is connected to a mounting plate, the inner wall of the recess of the mounting plate is connected to an electric rod, and the output shaft of the electric rod is connected to a support foot.

[0012] As a preferred embodiment of the hoisting machine with high stability according to this utility model, the support leg can be connected to the mounting plate for lifting via an electric rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The coordinated operation of the bidirectional threaded rod, guide rod, threaded sleeve, clamping block, and servo motor effectively enhances the stability of the hoisting machine. When the operator connects and starts the servo motor, its output shaft drives the bidirectional threaded rod to rotate. As the rod rotates, the threaded sleeves move closer together along their threaded paths. This causes the clamping block to move, which in turn moves the guide sleeve along the surface of the guide rod. The approaching clamping blocks securely hold the load lifted by the electric hoist crane, further restrained by the baffle. This design effectively prevents the load from swaying due to inertia during movement, significantly improving the stability of the hoist and ensuring safe and efficient hoisting operations.

[0014] The mounting plate, electric boom, and support feet work together to provide additional stability for the hoist. When the operator connects the electric boom to the power supply and starts it, the output shaft extends, pushing the support feet closer to the ground. Once the support feet contact the ground, a stable fulcrum is formed, further enhancing the overall stability of the hoist and ensuring safer and more reliable operation. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-5 This utility model provides the following technical solution: a highly stable hoisting machine, including a support base 1, two support bases 1 are symmetrically arranged, universal rollers 2 are installed at the bottom of the support base 1, a rectangular support column 3 is connected to the top of the support base 1, a crossbeam 4 is connected to the top of the rectangular support column 3, an electric hoist crane 5 is fixedly connected to the surface of the crossbeam 4, a baffle 6 is fixedly connected between the two rectangular support columns 3, a bidirectional threaded rod 7 is rotatably connected inside the baffle 6 through a bearing, a guide rod 8 is assembled inside the baffle 6, a threaded sleeve 9 is threadedly connected to the surface of the bidirectional threaded rod 7, a guide sleeve 10 is sleeved on the surface of the guide rod 8, a clamping block 11 is connected to the bottom of the threaded sleeve 9 and the guide sleeve 10, and a servo motor 12 is connected to the side wall of the rectangular support column 3.

[0019] In practical use, the hoist mainly consists of a support base 1, omnidirectional rollers 2, rectangular support columns 3, crossbeams 4, and an electric hoist crane 5. Among them, the support base 1, omnidirectional rollers 2, rectangular support columns 3, and crossbeams 4 together form a gantry structure.

[0020] As a key lifting component of the hoisting machine, the electric hoist crane 5 operates on the following principle: the motor drives the winding drum to operate in both forward and reverse directions. When the winding drum rotates forward, it drives the wire rope to wind up, and the hook suspended on the wire rope connects to the goods. As the wire rope continues to wind up, the goods are gradually lifted. When the winding drum rotates in the reverse direction, the wire rope is released, and the goods can be lowered accordingly.

[0021] After the goods are lifted, the operator can move the gantry frame flexibly with the help of the universal rollers 2 installed at the bottom of the support base 1, so as to realize the transfer of goods between different positions and meet diverse lifting needs.

[0022] Preferably, the output shaft of the servo motor 12 passes through the rectangular support column 3 and is connected to the bidirectional threaded rod 7. The clamping block 11 can form a threaded reciprocating motion with the baffle 6 through the threaded sleeve 9 and the bidirectional threaded rod 7. The clamping block 11 can form a sliding connection with the baffle 6 through the guide sleeve 10 and the guide rod 8. The two clamping blocks 11 are symmetrical about the center of the baffle 6.

[0023] In actual use, when the operator connects the power supply to the servo motor 12 and starts it, the servo motor 12 immediately enters the working state, its output shaft starts to rotate, and then drives the bidirectional threaded rod 7 connected to it to start rotating.

[0024] As the bidirectional threaded rod 7 continues to rotate, the threaded sleeve 9 is subjected to the force of the threads and gradually moves closer to each other along the threaded trajectory on the surface of the bidirectional threaded rod 7. During this process, the threaded sleeve 9 is connected to the clamping block 11, thus causing the clamping block 11 to move together. The clamping block 11 is also connected to the guide sleeve 10, so the guide sleeve 10 will slide smoothly along the surface of the guide rod 8 under the action of the clamping block 11, ensuring the stability of the movement of the clamping block 11.

[0025] The clamping blocks 11, positioned close together, can tightly fit the goods lifted by the electric hoist crane 5, securing them firmly. Simultaneously, the baffle 6 further restricts the goods from the top, forming multiple layers of protection.

[0026] This ensures that even if the hoist generates inertia due to acceleration or deceleration during movement, the goods can be firmly secured, effectively preventing the goods from swaying due to inertia. This not only greatly improves the stability of the hoist's operation and reduces the risk of safety accidents caused by goods swaying, but also ensures that hoisting operations can be carried out safely, efficiently, and smoothly.

[0027] Preferably, a mounting plate 13 is connected to the bottom end of the support base 1, and an electric rod 14 is connected to the inner wall of the recess of the mounting plate 13. The output shaft of the electric rod 14 is connected to a support foot 15. The support foot 15 can be connected to the mounting plate 13 in a lifting connection through the electric rod 14.

[0028] In actual use, when the operator connects the power supply to the electric lever 14 and starts it, the electric lever 14 responds immediately, and its output shaft slowly extends, pushing the support foot 15 towards the ground. As the output shaft continues to extend, the support foot 15 gets closer and closer to the ground until it makes close contact with the ground.

[0029] Once the support leg 15 contacts the ground, it creates a solid and stable fulcrum beneath the hoist, further enhancing its overall stability and ensuring safer and more reliable operation.

[0030] Working principle: First, the operator uses the omnidirectional rollers 2 to easily move the hoist to the side of the goods to be transported, preparing for subsequent operations.

[0031] Once the hoist is in position, the operator connects and starts the power supply to the electric boom 14. The electric boom 14 responds quickly, its output shaft slowly extending and precisely propelling the support leg 15 smoothly towards the ground. As the output shaft continues to extend, the support leg 15 gets closer to the ground until it is firmly in contact with it. At this point, the support leg 15 is in contact with the ground, effectively creating a solid and reliable fulcrum under the hoist, further enhancing the overall stability of the hoist and providing a solid guarantee for subsequent hoisting operations.

[0032] Next, the electric hoist crane 5 begins operation. It first slowly lowers the wire rope, allowing the hook to smoothly connect with the cargo. After connection, the electric hoist crane 5 restarts, winding up the wire rope to smoothly lift the cargo. Once lifted, the top of the cargo contacts the bottom of the baffle 6, providing initial restraint for cargo stability.

[0033] Subsequently, the operator connects and starts the servo motor 12. The servo motor 12 immediately enters the working state, and its output shaft begins to rotate, driving the connected bidirectional threaded rod 7 to start rotating. As the bidirectional threaded rod 7 continues to rotate, the threaded sleeve 9 is subjected to the force of the thread, and gradually moves closer to each other along the thread trajectory on the surface of the bidirectional threaded rod 7.

[0034] During this process, since the threaded sleeve 9 is tightly connected to the clamping block 11, it will drive the clamping block 11 to move together. The clamping block 11 is also connected to the guide sleeve 10, so the guide sleeve 10 will slide smoothly along the surface of the guide rod 8 under the action of the clamping block 11, ensuring the accuracy and stability of the movement of the clamping block 11.

[0035] The clamping blocks 11, positioned close together, can tightly fit the goods lifted by the electric hoist crane 5, securing them firmly. Simultaneously, the baffle 6 further restricts the goods from the top, forming a multi-layered protection system.

[0036] In this way, even if the hoist generates inertia due to acceleration or deceleration during movement, the goods can be firmly secured, effectively avoiding the problem of goods swaying due to inertia. This not only greatly improves the stability of the hoist's operation and reduces the risk of safety accidents that may be caused by goods swaying, but also ensures that hoisting operations can be carried out safely, efficiently, and smoothly.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
