Description

Technical Field

[0001] The utility model relates to the field of load hanging devices, in particular to a sucker sling for large-format spherical shell products. Background Art

[0002] In industrial manufacturing, the handling of products with a relatively large area is generally involved. The handling efficiency determines the efficiency of the entire production line. Therefore, it is an inevitable trend to vigorously develop the automated and intelligent handling of products. Chinese invention patent with publication number CN117361284A discloses a vacuum permanent magnet composite sucker sling. The sucker sling has a linear sling base frame. A plurality of suckers are arranged at intervals at the bottom of the sling base frame through a connecting device. A vacuum pump, a control box, a power supply mechanism, a negative pressure alarm, and a signal receiver are arranged at the top of the sling base frame. The vacuum pump is connected to the suckers through an air pipe and is used to pump out the air in the suckers. The negative pressure alarm is wirelessly connected to the control box and can timely monitor the pressure change in the suckers and give an alarm before the negative pressure approaches the warning value to avoid the loss of adsorption force of the sling due to too low negative pressure. When sucking a product, the suckers of the sucker sling are in contact with the product. The control box controls the vacuum pump to start to evacuate the air in the suckers. At the same time, the control box monitors the negative pressure in the suckers. After the vacuum pumping is completed, the traveling crane can realize the transfer of the product. After the transfer is completed, the control box controls the vacuum pump to stop working to complete the operation of releasing the product by the suckers. Among them, the main beam of the sucker sling is linear, and the suckers under the sling base frame are also arranged linearly along the length direction of the sling base frame. The linearly arranged sucker sling is only suitable for sucking plate-shaped objects or objects with a flat upper part and is difficult to realize the sucking of spherical shell products.

[0017] The Chinese invention patent with the publication number CN117361284A discloses a vacuum permanent magnet composite suction cup lifting appliance. The lifting appliance has a lifting appliance base frame. A suction cup capable of sucking an object is arranged at the lower part of the lifting appliance base frame. A vacuum pump, a control mechanism, etc. are arranged on the lifting appliance base frame. The control mechanism can control the vacuum pump to extract the air in the suction cup, so that the suction cup can stably suck the object. Among them, the lifting appliance base frame of the suction cup lifting appliance is linear, and the suction cups arranged below it are also linearly arranged. The linearly arranged suction cups are only suitable for sucking plate-shaped objects or objects with a flat upper part, and it is difficult to realize the suction of spherical shell products.

[0018] The present utility model proposes a brand-new technical solution for the problems existing in the above technical solution. The core concept of the present utility model is: to set a suspension base and a support arm radiating and extending outward with the suspension base as the center, and set the suction cup on the support arm. In this way, the suction cup can be distributed at different positions on the spherical surface according to the structure of the support arm, which is adapted to the shape of the spherical shell product, and the suction of the spherical shell product can be realized.

[0019] Based on the above utility model concept, a suction cup lifting appliance for large-format spherical shell products of the present utility model includes a lifting appliance base frame. The lifting appliance base frame includes a main frame 1 with hanging ears at the upper part that can cooperate with the hanging structure of the crane, and also includes a suspension base 9 and as Figure 1The arm 6 radiates and extends outward with the suspension base 9 as the center. Suction cups 4 are provided on each arm to adsorb different parts of the spherical surface of spherical shell products. The suction cups can be distributed in the same circumferential direction on the arm or in different circumferential directions on the arm. At this time, the suction cups are distributed at different positions on the spherical surface according to the structure of the arm, which is adapted to the shape of the spherical shell products, and the suction of the spherical shell products can be realized. A vacuum pump is arranged on the sling base frame to provide negative pressure to the suction cup 4. The vacuum pump is equipped with a control system. The vacuum pump is connected to the suction cup 4 through a suction pipe. The control mechanism can control the vacuum pump to provide negative pressure to the suction cup 4. The vacuum pump and the control mechanism in this embodiment are both integrated in the rechargeable module machine 2. Of course, the rechargeable module machine 2 can also integrate an adaptive alarm mechanism and an indicator light. When the adsorption vacuum of the vacuum pump to the suction cup 4 reaches the preset value, it can stop working. At this time, the green light on the rechargeable module machine 2 lights up, and the transfer of spherical shell products can be carried out; when the pressure is insufficient, the red light on the rechargeable module machine 2 lights up and automatically enters the state of adsorption vacuum to ensure the reliable adsorption of the suction cup 4 to the product. Of course, in other embodiments, the vacuum pump, the control mechanism, the adaptive alarm mechanism and the indicator light can also be arranged separately. A pneumatic hand-operated valve 3 is also arranged on one side of the suspension base 9. When the pneumatic hand-operated valve 3 is pressed, the suction pipe can be opened to make the suction cup adsorb. When the pneumatic hand-operated valve 3 is closed, the suction cup can perform a vacuum-breaking operation. Arranging the pneumatic hand-operated valve 3 on one side of the suspension base 9 enables the staff to more conveniently approach and control the on-off of the air circuit, reduces the operation distance and facilitates the operation. In addition, in other embodiments, the pneumatic hand-operated valve can also be arranged on the upper part of the suspension base, as long as its position is convenient for operation.

[0020] During use, place the spherical shell product in place, use a crane to move the large-format spherical shell product suction cup sling to the corresponding position of the spherical shell product, so that the suction cup 4 can be in close contact with the spherical shell product. Then the control system controls the vacuum pump to provide negative pressure to the suction cup 4. After the suction cup 4 adsorbs the spherical shell product in place, the transfer of the spherical shell product can be realized by using a crane.

[0021] In this embodiment, the arm 6 includes an inclined section extending downward. The inclined sections of each arm 6 are on the same rotating surface with the suspension base 9 as the center. The suction cup 4 is movably connected to the inclined section. Setting the suction cup 4 on the inclined section of the arm 6 can make the inclination angle of the suction cup 4 adapt to the spherical shell product and improve the reliability of the suction cup adsorption. In addition, in other embodiments, the arm can also extend horizontally outward, and the suction cup is connected to the arm through a suspension chain. The suction cup on the suspension chain has a certain degree of freedom, so the suction cup can also be inclined at a certain angle to adsorb the spherical shell product to achieve the reliability of adsorption. Of course, the suction cup can also be movably installed on the arm through a spherical hinge structure to realize the adjustable angle of the suction cup.

[0022] In this embodiment, the suction cup 4 is adjustably connected to the support arm 6 along the length direction of the support arm 6. The adjustable position of the suction cup 4 on the support arm 6 means that the suction cup lifting device can easily adapt to spherical shell products with different diameters and sizes, improving the flexibility of the suction cup lifting device. It can also ensure that the suction cups 4 are more evenly and reasonably distributed on the spherical shell products, helping to increase the adsorption area and adsorption force of the suction cups 4, thereby improving the stability of the lifting process. In addition, in other embodiments, if the suction cup lifting device only sucks spherical shell products of the same specification, after adjusting the angle of the suction cup, the suction cup can also be fixedly installed on the support arm.

[0023] In this embodiment, a collar 7 that can cooperate with the support arm 6 and slide thereon is provided on the support arm 6. The collar 7 is fixed to the support arm by a setscrew. The suction cup 4 is adjustably connected to the support arm 6 through the collar 7. The method of using the collar 7 and the setscrew to achieve adjustable suction cup position is simple and reliable. At the same time, by setting the suction cup 4 on the collar 7, it is also convenient to replace and repair the suction cup 4 when the suction cup 4 is damaged, improving the maintenance efficiency. In this embodiment, the cross-section of the support arm is square, so the cross-section of the collar is also square. Of course, when the cross-section of the support arm is circular or polygonal, the cross-section of the collar can also be set to circular or polygonal to achieve the adaptation of the two. In addition, in other embodiments, the adjustable position of the suction cup can also be achieved through a threaded structure. A support arm with a circular cross-section can be used, and external threads can be provided on the inclined section of the support leg. A circular collar is sleeved on the support leg, and the position of the collar is fixed by screwing a nut.

[0024] In this embodiment, there are two suction cups 4 connected to the same collar 7, and they are arranged oppositely on both sides of the support arm 6. The suction cups 4 arranged on both sides can provide a larger adsorption area, thereby enhancing the adsorption force on the spherical shell products and improving the reliability of the adsorption of the suction cups 4. In addition, it is easy to think that a suction cup 4 can be provided on one side of the collar 7 or at the bottom of the collar 7, as long as it is ensured that the suction cup can reliably adsorb the spherical shell products.

[0025] In this embodiment, the support arm 6 is adjustably connected to the suspension base 9 in the radial direction; or the support arm is fixedly connected to the suspension base and is a telescopic support arm. The specifications of spherical shell products are diverse. It is difficult for a support arm 6 with a fixed length to suck spherical shell products of different specifications, and it is also difficult to ensure that the suction cups 4 on the support arm 6 can fit the spherical shell products, which may lead to unreliable suction of the spherical shell products by the suction cups 4. Therefore, the support arm is adjustably connected to the suspension base 9, or a linear telescopic support arm with adjustable length is used. The telescopic support arm slopes downward and is directly connected to the suspension base 9. In this way, the length of the support arm can be adjusted to ensure that the position of the suction cup 4 can fit the spherical shell products, realizing reliable suction of the spherical shell products by the suction cup 4, and also enabling the lifting device to be applicable to a wider range of products, improving the versatility and use efficiency of the equipment.

[0026] In this embodiment, the support arm 6 is a bent arm including a horizontal section and an inclined section. The inclined section extends downward. The horizontal section is inserted and sleeved with the suspension base 9 in the radial direction and is provided with a locking structure for locking the two in the required position. The suspension base 9 is provided with square tubes that radiate horizontally outward and can be inserted and matched with the support arm 6. Locking holes are evenly arranged on the square tubes and the horizontal section of the support arm. When the support arm 6 slides to the corresponding position, the locking holes on the support arm 6 correspond to the locking holes on the square tubes. At this time, a locking pin can be inserted to fix the two, thereby realizing the adjustable length of the support arm 6. In addition, in other embodiments, spring snap buttons can be evenly arranged on the horizontal section of the support arm, and clamping grooves can be arranged on the square tubes. When the support arm slides to the relative position, the spring snap buttons on the support arm can pop up and cooperate with the clamping grooves on the square tubes to fix the two. Of course, in other embodiments, the support arm can also be set as an arc-shaped rod with an unadjustable length. The arc-shaped rod is directly connected to the suspension base as long as the suction cups installed on it can adsorb spherical shell products.

[0027] In this embodiment, a reinforcing diagonal brace 8 is provided at the bending position of the support arm 6. At the bending position of the support arm 6, due to the sudden change in shape, stress concentration often occurs. The reinforcing diagonal brace 8 can improve the stress distribution, effectively resist the deformation caused by external forces, maintain the overall shape and stability of the support arm 6, and improve the reliability of the suction process.

[0028] In this embodiment, the vacuum pump and the control system are arranged above the suspension base 9. If the vacuum pump and the control system are placed below the suspension base 9, it will interfere with the adsorption of the suction cup to the spherical shell product. By placing the vacuum pump and the control system (i.e., the rechargeable modular machine 2) above the suspension base 9 and placing it inside the main frame 1, at this time, the gravity of the rechargeable modular machine 2 acts on the center of the suspension base 9, so that the suction cup sling will not be offset. At the same time, it can also avoid interference during the adsorption process of the rechargeable modular machine 2 and the product.

[0029] In this embodiment, safety hooks 5 are provided on at least part of the support arm 6. After the suction cup adsorbs the spherical shell product in place, the suction cup sling can be slightly lifted by the crane, and then the safety hook 5 is used to hook the edge of the spherical shell product, which helps to reduce the risk of product offset caused by shaking or product dropping caused by insufficient suction during the hoisting process. The safety hook 5 of this embodiment is arranged on the spaced support arms 6 and is at the end of the support arm 6. It is easy to think that in other embodiments, hooks can be arranged at the end of each support arm 6.

The patent protection scope of the present invention is subject to the claims. All equivalent structural changes made by using the description and drawings of the present invention should be included in the protection scope of the present invention by the same token.
