Description

Technical Field

[0001] This utility model relates to the technical field of vacuum suction lifting machines, and specifically discloses a vacuum suction lifting machine with a dual-circuit vacuum circuit. Background Technology

[0002] Vacuum suction lifters are efficient and safe material handling equipment. They utilize the negative pressure suction force generated by a vacuum pump to firmly adhere vacuum suction cups to the surfaces of various materials, achieving contactless material handling. Due to their ease of operation, adaptability, and low maintenance costs, this equipment is widely used in manufacturing, logistics, and other industries. The main components of a vacuum suction lifter include a frame, load-bearing beams, a vacuum pump, and vacuum suction cups. These components work together to ensure the normal operation of the equipment and the safe handling of materials.

[0003] Although vacuum suction lifters play an important role in material handling, they still have some shortcomings. Existing vacuum suction lifters may experience problems when the vacuum pump malfunctions. Due to the roughness of the object's surface, it may be difficult to maintain effective suction, causing the object on the vacuum suction cup to gradually deflate and potentially fall. This could not only damage the material but also threaten the safety of operators and even lead to production accidents. To improve the operational safety of vacuum suction lifters, this utility model proposes a new type of vacuum suction lifter. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vacuum suction lifting machine with a dual-circuit vacuum circuit.

[0005] This utility model discloses a vacuum suction lifting machine with a dual-circuit vacuum circuit, which adopts the following technical solution:

[0006] A vacuum suction lifting machine with dual vacuum circuits includes a frame and a support beam mounted on the frame. The frame contains two independently operating vacuum circuit assemblies. The left side of the support beam has at least two left-side vacuum suction cups, and the right side of the support beam has at least two right-side vacuum suction cups. One of the vacuum circuit assemblies is connected to at least one left-side vacuum suction cup and at least one right-side vacuum suction cup, and the other vacuum circuit assembly is connected to at least one left-side vacuum suction cup and at least one right-side vacuum suction cup.

[0007] Preferably, the vacuum levels of the two vacuum circuit components are not the same.

[0008] Preferably, the supporting beam is provided with a left suction cup frame and a right suction cup frame. Multiple left vacuum suction cups are provided on the left suction cup frame along the axial direction of the supporting beam and perpendicular to the axial direction of the supporting beam, respectively. Multiple right vacuum suction cups are provided on the right suction cup frame along the axial direction of the supporting beam and perpendicular to the axial direction of the supporting beam, respectively. The number of left and right vacuum suction cups connected to the same vacuum circuit assembly are the same and they are symmetrically distributed.

[0009] Preferably, both the left vacuum suction cup and the right vacuum suction cup are provided with connecting seats for being movably sleeved on the supporting beam. The supporting beam is provided with a plurality of connecting holes at intervals, and the connecting seats are fixed to the supporting beam by bolts connecting the connecting holes.

[0010] Preferably, the vacuum circuit assembly includes a vacuum pump, a vacuum dial, and a manifold that connects the vacuum pump and the vacuum suction cup to the air passage.

[0011] Preferably, the frame is provided with two pressure-holding gas tanks, each assembled with a corresponding vacuum pump of a vacuum circuit assembly. The pressure-holding gas tanks are connected to the corresponding shunt pipes of the vacuum circuit assemblies and are used to distribute vacuum to the corresponding vacuum suction cups. The pressure-holding gas tanks are provided with one-way valves, which are used to cut off the passage between the vacuum pumps and the atmosphere.

[0012] Preferably, the pressure-holding gas tank is equipped with a pressure sensor.

[0013] Preferably, the frame is equipped with a buzzer alarm and an alarm light that are electrically connected to the pressure sensor.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] This invention features two vacuum circuit components. Even if one component malfunctions or leaks, the other component can still maintain normal operation of the vacuum suction cup, thus providing better protection for suction and lifting installation. Furthermore, since the vacuum suction cups, which are assembled with the two vacuum circuit components, are distributed on both sides of the supporting beam, the beam can be used to suction objects from both sides, maintaining better balance and preventing potential dangers caused by tilting to one side, thereby improving the safety of suction and lifting items.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A vacuum suction lifter with a dual vacuum circuit, as shown in the reference. Figure 1 The device includes a frame 1 and a support beam 2 mounted on the frame 1. The frame 1 contains two independently operating vacuum circuit assemblies 3. Specifically, each vacuum circuit assembly 3 includes a vacuum pump 31, a vacuum dial 32, and a manifold connecting the vacuum pump 31 to the vacuum suction cups. At least two left-side vacuum suction cups 4 are located on the left side of the support beam 2, and at least two right-side vacuum suction cups 5 are located on the right side of the support beam 2. One vacuum circuit assembly 3 is connected to at least one left-side vacuum suction cup 4 and at least one right-side vacuum suction cup 5, while the other vacuum circuit assembly 3 is connected to at least one left-side vacuum suction cup 4 and at least one right-side vacuum suction cup 5.

[0021] By designing a dual vacuum circuit system, when one of the vacuum circuit components 3 malfunctions or the pipeline leaks, only some of the vacuum suction cups on the support beam 2 will fail to maintain pressure, while the vacuum suction cups assembled with the other vacuum circuit component 3 can still maintain good adsorption capacity, thus providing a double safety function. Furthermore, since the vacuum suction cups assembled with the two vacuum circuit components 3 are distributed on both the left and right sides of the support beam 2, the support beam 2 can maintain balance from left to right, avoiding the danger of one side tipping over and improving the safety of vacuum-lifted objects.

[0022] As a preferred embodiment, the frame 1 is equipped with two pressure-holding gas tanks (not shown in the figure), each connected to a corresponding vacuum pump 31 of a vacuum circuit assembly 3. The pressure-holding gas tanks are connected to corresponding distribution pipes of the vacuum circuit assembly 3 and are used to distribute vacuum to the corresponding vacuum suction cups. Each pressure-holding gas tank is equipped with a one-way valve to cut off the passage between the vacuum pump 31 and the atmosphere. By adopting this design, in the event of a power outage, the pressure-holding gas tanks maintain pressure on the vacuum suction cups, improving suction and lifting safety. Furthermore, the vacuum pump 31 can stop operating when it reaches a predetermined negative pressure, at which point the pressure-holding gas tanks maintain pressure on the vacuum suction cups until a predetermined time has elapsed before restarting. This intermittent operation of the vacuum pump 31 saves power.

[0023] As a preferred option, the pressure-holding gas tank is equipped with a pressure sensor (not shown in the figure), and the frame 1 is equipped with a buzzer alarm and an alarm light 33 that are electrically connected to the pressure sensor. By adopting the above design, the pressure sensor can be used to visually display the vacuum value of the vacuum suction cup. When the pressure is lower than the set pressure, the buzzer alarm sounds and the alarm light 33 illuminates to remind the operator, thus providing better safety assurance.

[0024] As a preferred option, the two vacuum circuit components 3 are set with different vacuum levels. By setting up two vacuum circuit components 3, one with a high vacuum level and the other with a low vacuum level, when the adsorbed object is of low strength or light weight, one of the vacuum circuit components 3 with a lower vacuum level can be selected for suction and lifting, avoiding damage to the object caused by excessive negative pressure and saving power consumption. When the adsorbed object is of high strength or heavy weight, one of the vacuum circuit components 3 with a higher vacuum level can be selected for suction and lifting, or both vacuum circuit components 3 can be selected for suction and lifting simultaneously. By adopting the above design, the operational flexibility of the dual vacuum circuit system vacuum suction and lifting machine is improved.

[0025] In this embodiment, both the left vacuum suction cup 4 and the right vacuum suction cup 5 are provided with connecting seats 6 for movably mounting on the supporting beam 2. The supporting beam 2 has several connecting holes 21 spaced apart, and the connecting seats 6 are fixed to the supporting beam 2 by bolts and connecting holes 21. By adopting the above design, the position or number of vacuum suction cups can be adjusted according to the size of the object, improving the flexibility and adaptability of use, as well as the reliability and safety of the suction and lifting process.

[0026] In other embodiments, the supporting beam 2 may be equipped with a left suction cup frame and a right suction cup frame. Multiple left vacuum suction cups 4 are provided on the left suction cup frame along the axial direction of the supporting beam 2 and perpendicular to the axial direction of the supporting beam 2, respectively. Multiple right vacuum suction cups 5 are provided on the right suction cup frame along the axial direction of the supporting beam 2 and perpendicular to the axial direction of the supporting beam 2, respectively. The number of left vacuum suction cups 4 and right vacuum suction cups 5 connected to the same vacuum circuit assembly 3 are the same and symmetrically distributed. By adopting the above design, the suction and lifting stability of the object is improved, the problem of center of gravity shift is better avoided, and the safety of the suction and lifting process is enhanced.

[0027] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
