[0011] In one embodiment of the present application, the adsorption assembly is installed on both sides of the main body through a mounting bracket; one end of the mounting bracket is fixed to the main body, and the other end extends in a direction away from the main body for mounting the suction cup.

[0024] The existing suction cup hanger usually includes a suction cup body and a vacuum generator, and a plurality of suction cups are installed at the bottom of the suction cup body. The suction cup is evacuated by the vacuum generator to achieve the adsorption effect.

[0025] However, during the use of the existing suction cup hanger, if any of the suction cups in the suction cup hanger is damaged or leaks, and the vacuuming speed of the vacuum generator is slower than the speed of the leak, the object on the suction cup hanger may fall off, posing a safety hazard and causing personal injury accidents in serious cases. Therefore, a vacuum suction cup hanger is proposed to solve the above problems.

[0026] The scheme is further illustrated by the following examples: Figure 1 Schematic diagram of a vacuum suction cup hanger according to an embodiment of the present invention. Figure 2 yes Figure 1 In this embodiment, the side view of the vacuum suction cup lifting device is shown in FIG. Figure 1 The left and right directions in the figure are the lateral directions of the vacuum cup hanger. Figure 1 The up and down direction in the figure is the longitudinal direction of the vacuum suction cup hanger.

[0027] See also Figure 1 The vacuum suction cup hoist of this embodiment can be used to hoist objects, such as steel plates, iron plates, stainless steel plates, etc.

[0028] Specifically, the vacuum suction cup lifting device may include a main body 10, a vacuum generator 30 and two adsorption components 20. Among them, two independent vacuum channels 11 may be provided inside the main body 10. The two adsorption components 20 may be arranged on opposite sides of the main body 10 in the horizontal direction, and the adsorption components 20 may include a plurality of suction cups 21 arranged at intervals along the longitudinal direction of the main body 10, and the suction cups 21 are connected to the vacuum channels 11. The vacuum generator 30 is installed on the main body 10 to provide negative pressure. The vacuum generator 30 is respectively connected to the two vacuum channels 11, so that the plurality of suction cups 21 can be adsorbed on the surface of the object through negative pressure, thereby lifting the object.

[0029] It should be noted that the vacuum generator 30 can be configured as a vacuum pump to evacuate the vacuum channel 11.

[0030] In this embodiment, the vacuum channel 11 can be configured as a vacuum hose 12. The vacuum hose 12 is connected between the vacuum generator 30 and the suction cup 21 of the adsorption assembly 20, so that the vacuum generator 30 can evacuate the suction cup 21 through the vacuum hose 12, so that the suction cup 21 can be adsorbed on the surface of the object, that is, each suction cup 21 is connected to the vacuum generator 30 through the vacuum hose 12, so that the vacuum generator 30 can drive the suction cup 21 to be adsorbed on the surface of the object.

[0031] In some other embodiments, the vacuum channel 11 can be configured as a metal pipe or a plastic pipe, so that the suction cup 21 can be connected to the vacuum generator 30 through the metal pipe or the plastic pipe.

[0032] It should be noted that a hollow cavity may be provided on the main body 10, and the cavity may be divided into two independent mounting cavities, which may be used to mount the vacuum hose 12. Of course, the cavity may also be provided as an integral chamber, in which two vacuum hoses 12 are mounted.

[0033] See also Figure 1 The two adsorption components 20 are arranged on both sides of the main body 10, and in the same adsorption component 20, the number of suction cups 21 connected to the same vacuum channel 11 is the same.

[0034] Specifically, Figure 1 As shown, for the convenience of description, the two vacuum channels 11 can be respectively the first vacuum channel 111 and the second vacuum channel 112, and the two adsorption components 20 can be respectively the first adsorption component 201 and the second adsorption component 202. At the same time, among the multiple suction cups 21 constituting the two adsorption components 20, the suction cup 21 connected to the first vacuum channel 111 can be set as the first suction cup 211, and the suction cup 21 connected to the second vacuum channel 112 can be set as the second suction cup 212.

[0035] Therefore, the first suction component 201 is provided with the first suction cup 211 and the second suction cup 212 at the same time, and the number of the first suction cup 211 is the same as the number of the second suction cup 212. Similarly, the second suction component 202 is also provided with the first suction cup 211 and the second suction cup 212 at the same time, and the number of the first suction cup 211 is the same as the number of the second suction cup 212.

[0036] It should be noted that in actual use, when a suction cup 21 is damaged or leaks, it will affect the vacuum channel 11 connected to the suction cup 21 and multiple suction cups 21 connected to the vacuum channel 11, causing the vacuum channel 11 and the suction cup 21 to release pressure at the same time, thereby affecting the suction force of the suction cup 21 connected to the vacuum channel 11. However, the suction cup 21 connected to another vacuum channel 11 is not affected by the pressure release, so the suction force is maintained, ensuring the suction force of the sling on the object and preventing the object from falling immediately.

[0037] For example, when a first suction cup 211 in the first adsorption component 201 or the second adsorption component 202 leaks, it will cause pressure relief in the first vacuum channel 111, thereby reducing the adsorption force of multiple first suction cups 211 connected to the first vacuum channel 111, that is, the suction force of the first suction cups 211 in the first adsorption component 201 and the second adsorption component 202 will both decrease, which may cause the first suction cup 211 to be unable to adsorb the surface of the object in severe cases. However, at this time, the second suction cups 212 in the first adsorption component 201 and the second adsorption component 202 have no leakage, and the second vacuum channel 112 has no pressure relief, so that the second suction cup 212 can still be adsorbed on the surface of the object, and the second suction cup 212 can lift the object to prevent the object from falling immediately, thereby ensuring the safety of the vacuum suction cup hoist lifting the object.

[0038] See also Figure 1 In this embodiment, a plurality of suction cups 21 connected to the same vacuum channel 11 may be located on opposite sides of the main body 10 in the lateral direction, so that the lifting device can lift the object stably.

[0039] Among them, the plurality of suction cups 21 connected to the same vacuum channel 11 are provided on opposite sides of the main body 10 in the lateral direction, and the number of the suction cups 21 is the same, so that the lifting device can lift the object stably.

[0040] In some other embodiments, multiple suction cups 21 connected to the same vacuum channel 11 can be symmetrically arranged about the center of the main body 10, so as to ensure that after the sling lifts the object, the suction forces of the suction cups 21 connected to the same vacuum channel 11 on the object remain balanced, thereby avoiding the situation where the suction force of the sling on the object is unbalanced due to air leakage in another vacuum channel 11 and the suction cups 21 connected thereto.

[0041] Specifically, the first suction cups 211 connected to the first vacuum channel 111 are symmetrically arranged about the center of the main body 10, and the second suction cups 212 connected to the second vacuum channel 112 are also symmetrically arranged about the center of the main body 10. Therefore, even if the vacuum suction cup hoist is lifting an object, when one vacuum channel 11 is accidentally depressurized, the suction cup 21 connected to the other vacuum channel 11 can still stably absorb the object and ensure the force balance of the object, so as to avoid the object shaking relative to the hoist or even falling due to the change of the suction force of the hoist when an accident occurs to the hoist.

[0042] It should be noted that two adjacent suction cups 21 along the longitudinal direction of the main body 10 are respectively connected to two vacuum channels 11, that is, in the longitudinal direction of the main body 10, the first suction cup 211 and the second suction cup 212 in the first adsorption component 201 or the second adsorption component 202 are alternately arranged, that is, the first suction cup 211 and the second suction cup 212 are adjacent to each other, and a second suction cup 212 is arranged between any two adjacent first suction cups 211.

[0043] Of course, in some other embodiments, in the first adsorption component 201 or the second adsorption component 202, the first suction cup 211 and the second suction cup 212 may not be arranged alternately, that is, the adjacent side of the first suction cup 211 may be either the first suction cup 211 or the second suction cup 212, but on both sides of the transverse direction of the main body 10, the first suction cup 211 and the second suction cup 212 are respectively arranged symmetrically about the center of the main body 10. Exemplarily, for example, the first suction cup 211 is provided on both sides of the first suction cup 211, respectively, or the first suction cup 211 is provided on both sides of the first suction cup 211. Specifically, for example, in the longitudinal direction of the main body 10, two first suction cups 211, one second suction cup 212, two first suction cups 211, and one second suction cup 212 are arranged in sequence; or, in the longitudinal direction of the main body 10, three first suction cups 211, two second suction cups 212, three first suction cups 211, and two second suction cups 212 are arranged in sequence.

[0044] See also Figure 1 , two suction cups 21 arranged in the transverse direction of the main body 10 are connected to the two vacuum channels 11 respectively, and the connection line of the two suction cups 21 extends in the transverse direction of the main body 10. That is, in the transverse direction of the main body 10, the second suction cup 212 in the first suction component 201 and the first suction cup 211 in the second suction component 202 are located on the same straight line; or, the first suction cup 211 in the first suction component 201 and the second suction cup 212 in the second suction component 202 are located on the same straight line, so that the suction force of the first suction cup 211 and the second suction cup 212 on the object is evenly distributed, so that when the first vacuum channel 111 or the second vacuum channel 112 leaks, the suction cup 21 connected to the other vacuum channel 11 can lift the object smoothly.

[0045] Of course, in some other embodiments, the first suction cup 211 and the second suction cup 212 may also be staggered in the lateral direction of the main body 10, but the first suction cup 211 or the second suction cup 212 located on both sides of the longitudinal direction of the main body 10 are each symmetrically arranged about the center of the main body 10.

[0046] See also Figure 1 The vacuum suction cup lifting device may further include a detection component 41 and a controller. The detection component 41 is connected to the two vacuum channels 11 to detect the vacuum degree of the two vacuum channels 11 and form a detection signal.

[0047] In this embodiment, the detection component 41 may include two electric contact pressure gauges, and the two electric contact pressure gauges are respectively connected to the two vacuum channels 11 to respectively detect the vacuum degrees of the two vacuum channels 11.

[0048] At the same time, the controller is electrically connected to the detection assembly 41 and the vacuum generator 30 respectively, so as to control the opening or closing of the vacuum generator 30 through the detection signal.

[0049] In this embodiment, the vacuum suction cup lifting device may further include a control valve group.

[0050] The control valve group is connected to the two vacuum channels 11 respectively to open or close the two vacuum channels 11. The control valve group is also electrically connected to the controller so that the controller can control the opening or closing of the control valve group.

[0051] The control valve group includes two solenoid valves, and the two solenoid valves are respectively connected to two vacuum channels 11. When the control system of the vacuum suction cup hoist fails, the controller controls the control valve group to shut down to cut off the atmospheric circuit of the vacuum channel 11 and maintain the vacuum degree of the vacuum channel 11, so that the object adsorbed by the adsorption component 20 does not fall, ensuring the safety of the lifting process.

[0052] In addition, the vacuum cup lifter may also include an indicator light assembly.

[0053] Specifically, the indicator light assembly is mounted on the main body 10 and electrically connected to the controller so that the controller controls the operation of the indicator light assembly through a detection signal. When the two vacuum channels 11 are under negative pressure, the indicator light assembly displays green; when the two vacuum channels 11 are under normal pressure, the indicator light assembly displays red.

[0054] The indicator light assembly can facilitate the operator to identify whether the adsorption assembly 20 is adsorbed on the object, thereby ensuring the operator's operating safety.

[0055] See also Figure 2The adsorption assembly 20 may further include a plurality of guide rods 22. One end of the guide rod 22 is connected to the suction cup 21, and the other end of the guide rod 22 is connected to the main body 10, and can move relative to the main body 10 to drive the suction cup 21 to move relative to the main body 10, thereby adjusting the distance between the suction cup 21 and the main body 10, so that the adsorption assembly 20 can be adsorbed on the surface of objects of different shapes.

[0056] In this embodiment, the guide rod 22 extends vertically and can move relative to the main body 10 , thereby driving the suction cup 21 to move relative to the main body 10 .

[0057] See also Figure 1 and Figure 2 The adsorption assembly 20 can be installed on both sides of the main body 10 through the mounting bracket 13.

[0058] The suction cup 21 of the adsorption assembly 20 is installed on both sides of the main body 10 through the mounting bracket 13. Specifically, one end of the mounting bracket 13 is fixed on the main body 10, and the other end extends away from the main body 10 for mounting the suction cup 21.

[0059] In this embodiment, one end of the mounting bracket 13 away from the main body 10 is connected to the guide rod 22 , and the guide rod 22 can move vertically relative to the mounting bracket 13 .

[0060] See also Figure 2 The vacuum suction cup lifting device may further include a manual control box 51 and an electric control box 52 .

[0061] The electric control box 52 is used to install the electrical components of the vacuum suction cup lifting device, such as the system power supply, to ensure that the vacuum suction cup lifting device can be powered on and work. Specifically, the electric control box 52 is electrically connected to the vacuum generator 30, and the manual control box 51 is electrically connected to the electric control box 52, so that the manual control box 51 controls the opening or closing of the vacuum generator 30 through the electric control box 52.

[0062] In actual use, the operator can manually drive the vacuum suction cup hoist to move to the object to be lifted, and control the adsorption component 20 to adsorb on the surface of the object through the hand control box 51. Or after the vacuum suction cup hoist lifts the object to the corresponding position, the operator releases the lifted object through the hand control box 51.

[0063] Specifically, when the operator controls the vacuum suction cup lifter through the manual control box 51, and the vacuum generator 30 is in working state, when the detection component 41 detects that at least one of the two vacuum channels 11 is still intact, the detection component 41 sends a detection signal to the controller, and the controller controls the vacuum generator 30 to continue to turn on the vacuum function, so that the adsorption component 20 can be firmly adsorbed on the object, and the vacuum suction cup lifter can lift the object or prevent the object from falling.

[0064] In summary, two independent vacuum channels 11 are provided in the main body 10 of the vacuum suction cup hoist, and the vacuum generator 30 is installed on the main body 10 and connected to the two vacuum channels 11 to provide negative pressure. The adsorption assembly 20 is provided with a plurality of suction cups 21, and the plurality of suction cups 21 are arranged at intervals along the longitudinal direction of the main body 10. The two adsorption assemblies 20 are arranged on both sides of the main body 10, and the number of suction cups 21 connected to the same vacuum channel 11 is the same, that is, in the same adsorption assembly 20, the number of suction cups 21 connected to the two vacuum channels 11 is the same, thereby ensuring that in the two vacuum channels 11, when one vacuum channel 11 fails, the suction cup 21 connected to the other vacuum channel 11 can still adsorb objects to prevent the objects from falling immediately, thereby ensuring the safety of the hoisting of the hoist.

[0065] In this embodiment, the working process of the vacuum suction cup hoist is as follows: open the electric control box 52 to power on the vacuum suction cup hoist. Move the vacuum suction cup hoist to the object to be hoisted, and turn on the vacuum generator 30 so that the vacuum channel 11 generates a vacuum and the adsorption component 20 is adsorbed on the object. The detection component 41 detects the vacuum degree in the vacuum channel 11. When the detection component 41 meets the requirements, the green light of the indicator light component lights up. At this time, the vacuum suction cup hoist can drive the object to move and place it in a suitable preset position. At this time, turn off the vacuum generator 30 so that the vacuum channel 11 returns to normal pressure, and the red light of the indicator light component lights up. At this time, the adsorption component 20 is detached from the surface of the object, and the vacuum suction cup hoist can be removed, thereby completing a lifting work.

Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
