DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Please see attached Figure 1-11The European double-beam crane group and method for preventing shaking of this embodiment include a bridge frame 1, a trolley 2 is slidably connected to the bridge frame 1, two groups of symmetrically distributed double-drum winding machines 3 are arranged on the trolley 2, and two groups of first lifting ropes 4 are installed on each group of double-drum winding machines 3. The trolley 2 is provided with a first rope groove 5 matched with the first lifting rope 4, one end of the first lifting rope 4 is fixedly connected to the double-drum winding machine 3, and the other end of the first lifting rope 4 is fixedly connected to the bottom of the trolley 2. The middle parts of the two groups of first lifting ropes 4 are matched with lifting wheel groups 6, and the two groups of lifting wheel groups 6 are symmetrically distributed. The lifting wheel group 6 is rotatably connected to the lifting plate 7, and a hook 8 is provided under the lifting plate 7; along the connection direction of the first lifting rope 4, the lifting wheel group 6 includes a first lifting wheel 601, a reversing wheel 602 and a second lifting wheel 603 in sequence, the first lifting wheel 601 and the second lifting wheel 603 are rotatably installed on the lifting plate 7, the first lifting wheel 601 and the second lifting wheel 603 are respectively located on both sides of the lifting plate 7, the reversing wheel 602 is rotatably connected above the trolley 2, and the trolley 2 on both sides of the reversing wheel 602 is provided with a second rope groove 9 that cooperates with the first lifting rope 4.

[0031] The bridge frame 1 has four columns 101, and the four columns 101 are grouped in two. The two groups of columns 101 are located on the left and right sides of the trolley 2. A support beam 102 is installed on the upper end of each group of columns 101. A cross beam 104 slides between the two support beams 102. The cross beam 104 can slide forward and backward on the support beam 102. There are two cross beams 104, and a gap is left in the middle of the two cross beams 104. The front and rear sides of the trolley 2 are mounted on the cross beams 104, and the trolley 2 can move left and right on the cross beams 104. The first lifting rope 4 on the car 2 is located in the gap between the two crossbeams 104 and is suspended downward. There are two groups of double-drum winding machines 3 on the trolley 2. The two groups of double-drum winding machines 3 have the same rotation speed and rotate synchronously. There are two first lifting ropes 4 on each group of double-drum winding machines 3. There is a partition plate in the middle of the double-drum winding machines 3. The two first lifting ropes 4 are located in two different storage chambers of the double-drum winding machines 3. One end of the first lifting rope 4 is fixed under the trolley 2, and the other end of the first lifting rope 4 is fixed to the bottom of the trolley 2. The first lifting rope 4 is fixed on the double-drum winding machine 3 at one point, and the middle part of the first lifting rope 4 cooperates with the lifting plate 7 through the lifting wheel group 6. The lifting wheel group 6 winds the first lifting rope 4 into a W-shaped bending structure, so that the first lifting rope 4 has two action points on the lifting plate 7, and the two action points on the same first lifting rope 4 are respectively located on two mutually perpendicular sides of the lifting plate 7. The cooperation method between each first lifting rope 4 and the lifting wheel group 6 is the same as the above method. The four first lifting ropes 4 have eight action points on the lifting plate 7. When the double-drum winding machine 3 is winding, the rope length below the first lifting rope 4 becomes shorter, thereby driving the lifting plate 7 to move upward. In the process of upward movement, the sixteen lifting lines at eight action points have forces in different directions on the lifting plate 7. When the lifting plate 7 shakes, this force will offset the kinetic energy of the shaking, thereby ensuring the stability of the lifting plate 7 and ensuring the steady rise of the unit. The hook is located below the lifting plate 7, and the hook is convenient for hanging and taking the lifted objects, and convenient for hooking the packaged objects.

[0032] The lifting assembly is composed of a plurality of fixed pulleys and movable pulleys, wherein the first lifting wheel 601 and the second lifting wheel 603 are rotatably mounted on the lifting plate 7, the first lifting wheel 601 has four, the second lifting wheel 603 also has four, the first lifting wheel 601 and the second lifting wheel 603 are both movable pulleys, and due to the characteristics of the movable pulley, when the double-drum winding machine 3 is working, due to the cooperation of the movable pulley, the driving motor 10 under the same power can lift heavier objects, thereby improving the lifting load-bearing capacity of the unit, and the reversing wheel 60 2 is a fixed pulley, and the reversing wheel 602 is used to change the direction of the force applied by the first suspension rope 4, so that the first suspension rope 4 can be bent in a smoother way, thereby avoiding excessive friction at the bending part of the first suspension rope 4, ensuring the service life of the first suspension rope 4, and avoiding excessive wear of the first suspension rope 4 during the retraction and release process. In order to avoid interference between the suspension rope and the trolley 2, the trolley 2 is provided with a first rope groove 5 and a second rope groove 9 for the first suspension rope 4 to pass through, thereby ensuring that the first suspension rope 4 passes through the trolley 2 smoothly.

[0033] In order to improve the safety, stability and functionality of the device, electromagnetic brakes, overheat protectors, drive motors 10, overload limiters and rope guides 11 and other components are installed on the trolley 2 to work together with the double-drum winder 3, so as to achieve precise control of the movement of the trolley 2, the lifting and lowering of the first rope 4 and safety protection; the electromagnetic brake is a device that uses electromagnetic force to achieve braking: in the trolley 2, it is mainly used to quickly and effectively control the movement of the trolley 2 when stopping or emergency braking is required to ensure safety and stability. The electromagnetic brake has a fast response and adjustable braking force, and is very suitable for occasions that require precise control of speed and position; the overheat protector is a safety device used to monitor and prevent equipment from being damaged or causing a fire due to overheating. In the trolley 2 system, it may monitor the motor, circuit or other parts that are prone to heat. The temperature of the component will be automatically cut off or reduced if it detects that the temperature is too high to protect the entire system from damage; the drive motor 10 is the power source for the movement of the trolley 2. It converts electrical energy into mechanical energy to drive the movement of the trolley 2 in the left and right directions. The drive motor 10 is connected to the transmission system through a coaxially fixed first gear 12 to achieve power transmission. The first gear 12 is coaxially fixedly connected to the drive motor 10 to transmit the rotational motion of the motor to the second gear 13. The second gear 13 is fixedly connected to the double-drum winding machine 3 to further transmit the power to the double-drum winding machine 3, thereby driving the lifting of the first suspension rope 4; the above-mentioned electromagnetic brake, overheat protector, drive motor 10 and overload limiter are the same as the components in the existing electric hoist and are prior art, so they will not be introduced in too much detail here.

[0034] There are two groups of rope guides 11, and each group of rope guides 11 has two sliders 1103. The two sliders 1103 are opposite to the two winding parts of the double-drum winding machine 3. The sliders 1103 slide left and right with the car. The third gear 1101 is a key link in the transmission chain in the synchronous movement of the rope guide 11 and the double-drum winding machine 3. The third gear 1101 is meshed with the second gear 13 to receive power from the driving motor 10. The module of the third gear 1101 is smaller than that of the second gear 13. The reciprocating screw 1102 is a mechanical element that can convert rotational motion into linear motion. When the third gear 1101 rotates, since it is coaxially fixedly connected with the reciprocating screw 1102, it will drive the reciprocating screw 1102 to rotate. The reciprocating screw 1102 Different from the one-way thread of an ordinary screw rod, the reciprocating screw rod 1102 has thread grooves with different rotation directions. The thread on the reciprocating screw rod 1102 cooperates with the slider 1103 to convert the rotational motion into the linear motion of the slider 1103. Due to the double-rotational thread grooves on the reciprocating screw rod 1102, after the slider 1103 moves to the end of the thread groove of the reciprocating screw rod 1102, the slider 1103 starts the return motion, so that the slider 1103 can slide back and forth left and right. The reciprocating sliding stroke of the slider 1103 is equal to the general length of the double-drum winding machine 3. The first lifting rope 4 passes through the through hole 1104, and the slider 1103 adjusts the position of the first lifting rope 4. When winding, it is ensured that the first lifting rope 4 is arranged in parallel on the double-drum winding machine 3 to avoid the first lifting rope 4 being wound at one position of the double-drum winding machine 3.

[0035] The sliding wheel 604 is located in the second rope groove 9 and is rotatably connected thereto. The sliding wheel 604 can rotate freely in the rope groove, thereby reducing the friction resistance between the first rope 4 and the rope groove during the lifting process and improving the operating efficiency of the system; at the same time, the rotation of the sliding wheel 604 also helps to maintain the linearity and stability of the rope, preventing it from causing safety problems due to twisting or swinging; the rope anti-dropping block 605 is located adjacent to one side of the sliding wheel 604. The main function of this anti-dropping block 605 is to prevent the first rope 4 from accidentally falling out of the rope groove of the sliding wheel 604 during the lifting process. When the first rope 4 moves on the sliding wheel 604, the rope anti-dropping block 605 will provide a physical barrier to ensure that the first rope 4 always remains within the predetermined path.

[0036] The hook 8 below the lifting plate 7 is further extended to include an outer shell 14, a lifting chain 15, a chain winding roller 16, a fixing plate 17 and other components. The outer shell 14 is a component rotatably connected to the hook 8, which provides a platform for installing and supporting the lifting chain 15. The outer shell 14 has a certain strength and rigidity to bear the weight of the lifting chain 15 and the lifted goods; the chain winding roller 16 is a rotatable component, which winds or releases the lifting chain 15 by rotating, allowing the operator to control the lifting chain 15 by controlling the rotation of the chain winding roller 16 The length of the chain winding roller 16 can be adjusted to achieve the adjustment of the lifting height of the goods. The chain winding roller 16 is usually connected to a certain driving mechanism (such as a motor, a hand wheel, etc.) to achieve automatic or semi-automatic operation; the fixed plate 17 is a component fixedly connected to the lifting plate 7, which provides a stable installation base for the chain winding roller 16. The fixed plate 17 has sufficient strength and rigidity to ensure that the chain winding roller 16 will not be displaced or deformed during rotation; this design enables the hook 8 not only to directly lift the goods, but also to achieve more flexible control of the goods through the lifting chain 15 and the chain winding roller 16.

[0037] When it is necessary to lift the cargo, the operator first releases the lifting chain 15 by controlling the rotation of the chain winding roller 16 to lower the hook 8 to an appropriate position, and then firmly connects the hook 8 to the cargo. Next, the operator winds up the lifting chain 15 by rotating the chain winding roller 16 in the opposite direction, thereby lifting the cargo. During the lifting process, the operator can adjust the rotation speed and direction of the chain winding roller 16 at any time as needed to achieve precise control of the cargo lifting height.

[0038] Furthermore, the number of chain winding rollers 16 is increased to two groups, and new components such as a lifting pulley 18 and a cable arranger 19 are introduced, so that the lifting chains 15 are arranged symmetrically on both sides of the outer shell 14. The two lifting chains 15 have four groups of traction forces on the outer shell 14, which improves the stability of the lifting and lowering of the outer shell 14, improves the efficiency and stability of the lifting system, and ensures the smooth operation of the lifting chains 15.

[0039] The number of chain winding rollers 16 is increased to two groups, and two independent winding mechanisms are used to control the winding and releasing of the lifting chain 15. The two groups of chain winding rollers 16 can work synchronously. The lifting pulley 18 is a component installed in the outer shell 14 and allows the lifting chain 15 to bypass. Since there are two groups of lifting pulleys 18 and they are symmetrically distributed about the center of the hook 8, it can ensure that the lifting chain 15 remains balanced and stable during the lifting process. The lifting pulley 18 reduces the friction between the chain and the outer shell 14, improves the lifting efficiency, and extends the service life of the chain. Each group of lifting pulleys 18 is equipped with a lifting chain 15, for a total of two, and these two lifting chains 15 are respectively It passes around two sets of lifting pulleys 18 and is fixedly connected to two sets of chain winding rollers 16 respectively, which increases the redundancy of the lifting system and improves the reliability and safety of the system. Even if one of the chains fails, the other chain can continue to work to ensure the safe lifting of the goods. The chain winding roller 16 is equipped with two relatively movable cable arranging devices 19. The main function of the cable arranging device 19 is to ensure that the lifting chain 15 can be neatly arranged on the chain winding roller 16 during the chain winding and releasing process to avoid chain crossing, entanglement and confusion. The use of the cable arranging device 19 improves the operation efficiency of the chain and reduces failures and downtime caused by improper chain arrangement.

[0040] When it is necessary to lift the cargo, the operator releases or winds the lifting chain 15 by controlling the rotation of the two sets of chain winding rollers 16. The lifting chain 15 passes around the lifting pulley 18 and is neatly arranged on the chain winding roller 16 through the cable arranger 19. The two sets of chain winding rollers 16 can work independently or synchronously to achieve precise control and lifting of the cargo. During the lifting process, the lifting pulley 18 reduces the friction between the chain and the outer shell 14, thereby improving the lifting efficiency; and the cable arranger 19 ensures the smooth operation and neat arrangement of the chain.

[0041] The overall workflow when the present invention is used: Firstly, the bridge 1 serves as a supporting structure and provides a moving track for the trolley 2. In order to increase the stability of the movement of the trolley 2 on the bridge 1, a second slide rail is used to restrict the movement of the trolley 2. This design reduces the shaking of the trolley 2 during movement and improves the stability of the entire lifting system.

[0042] Secondly, two double-drum wire winders 3 are installed on the trolley 2, and the double-drum wire winders 3 have two first lifting ropes 4, and each first lifting rope 4 is equipped with a lifting wheel group 6. The first lifting rope 4 cooperates with the lifting wheel group 6 to bend the first lifting rope 4 into a W-shaped structure, so that the first lifting rope 4 has more lifting line options on the lifting plate 7. At the same time, the first lifting wheel 601 and the second lifting wheel 603 are movable pulleys, which makes the lifting plate 7 have a stronger lifting ability. Each double-drum wire winder 3 can independently control the two first lifting ropes 4 thereon, increasing the flexibility and accuracy of the lifting operation; the lifting plate 7 serves as a key component connecting the hook 8 and the first lifting rope 4, and four groups of lifting wheel groups 6 are arranged on it. These four groups of lifting wheel groups 6 ensure the stability of the lifting plate 7 during the lifting process through the mutual cooperation of the first lifting rope 4.

[0043] Finally, a lifting chain 15 is installed between the hook 8 and the lifting plate 7, so that the hook 8 can be flexibly adjusted relative to the lifting plate 7, which not only makes it convenient for the hook 8 to hang objects, but also limits the swing range of the hook 8 and the lifting chain through the stability of the lifting plate 7. The lifting chain 15 plays a key role between the hook 8 and the lifting plate 7. Through its rigid characteristics, it limits the extension distance of the hook 8 and the lifting chain 15 during the lifting process. This limitation greatly reduces the large-scale swing of the hook 8 when lifting objects, thereby ensuring the smooth lifting of the crane group.

[0044] This crane group achieves high stability and safety during the lifting process through design elements such as multi-point traction, stability restriction and rigid connection. At the same time, the configuration of the double-drum winding machine 3 and multiple sets of lifting wheel groups 6 improves the flexibility and accuracy of the lifting operation. The entire system can effectively avoid shaking and swinging during the lifting process, ensuring the safety and smooth transportation of the hoisted objects. Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

6. The European double-beam crane assembly for preventing swaying according to claim 1, characterized in that: The hook (8) is rotatably connected to an outer shell (14), the outer shell (14) is provided with a lifting chain (15), the other end of the lifting chain (15) is fixedly connected to a chain winding roller (16), the chain winding roller (16) is rotatably connected to a fixing plate (17), and the fixing plate (17) is fixedly connected to the lifting plate (7).

7. The European double-beam crane assembly for preventing swaying according to claim 6, characterized in that: There are two groups of chain winding rollers (16), and a lifting pulley (18) is rotatably connected to the outer shell (14). The lifting chain (15) passes around the lifting pulley (18), and the two ends of the lifting chain (15) are respectively fixedly connected to the two groups of chain winding rollers (16).

8. The European double-beam crane assembly for preventing swaying according to claim 7, characterized in that: There are two groups of lifting pulleys (18), which are symmetrically distributed about the center of the hook (8). The two groups of lifting pulleys (18) are equipped with two lifting chains (15). The chain winding roller (16) is equipped with two relatively movable wire arrangers (19), and the two lifting chains are fixedly connected to the chain winding roller (16) through the wire arrangers (19).

9. The method for preventing swaying of European double-beam lifting according to claim 1, characterized in that: The movement of the bridge frame (1) and the trolley (2) is stabilized by a second slide rail. Two double-drum winding machines (3) are installed on the trolley (2). Each double-drum winding machine (3) is equipped with two first lifting ropes (4). Each first lifting rope (4) is equipped with a set of lifting wheel groups (6). Each set of lifting wheel groups (6) has a first lifting wheel (601) and a second lifting wheel (603) that are rotatably connected to the lifting plate (7). After the first lifting rope (4) passes around the first lifting wheel (601) and the second lifting wheel (603), each first lifting rope (4) has four-point traction on the lifting plate (7). There are four lifting wheel groups (6) on the lifting plate (7). The first lifting ropes (4) on the four lifting wheel groups (6) cooperate with each other to prevent the lifting plate (7) from sliding when moving. The hook (8) is located at the bottom of the lifting plate (7). A lifting chain (15) is installed between the hook (8) and the lifting plate (7). The lifting chain (15) facilitates the hook (8) to hang objects. At the same time, under the action of the lifting plate (7), the extension distance of the lifting chain connected to the hook (8) is shortened, which greatly prevents the hook (8) from swinging in a large range when lifting objects, thereby ensuring the stable lifting of the crane group.
