Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to an anti-blocking vacuum suction cup lifting tool. Background Art

[0002] In modern industrial production, as an efficient and economical lifting tool, the vacuum suction cup lifting tool is widely used in the handling and positioning operations of various materials. The vacuum suction cup of the vacuum suction cup lifting tool relies on forming a vacuum environment inside the suction cup to adsorb and lift objects. However, there are some problems in practical applications.

[0003] First of all, after the vacuum suction cup of the vacuum suction cup lifting tool inhales impurities such as dust, debris or liquid, the impurities block the air flow, thereby reducing the suction force and affecting its normal operation. After these impurities are inhaled into the air extraction device, it may even cause damage to the air extraction device. In addition, the presence of impurities may also cause the suction cup to be unstable during the adsorption process, increasing the operation risk. To solve these problems, although there are some improvement measures in the market, such as using a filter screen. However, the filter screen is installed inside, and it is not easy to observe the blockage or damage of the filter screen, which is likely to cause potential safety hazards. Moreover, the shapes of impurities are diverse, such as needle-shaped debris generated by cutting metals. The needle-shaped debris may penetrate the filter screen and, with the huge suction force during air extraction, cause the air guide hose to be scratched or blocked at any place, making it difficult to check. The above problems lead to a sudden and inexplicable weakening of the adsorption force of the adsorbed object, and the blockage is not easy to detect. In the long run, it has great potential safety hazards. Summary of the Utility Model

[0004] Aiming at the above problems, the utility model provides an anti-blocking vacuum suction cup lifting tool, which can effectively solve the problem of potential safety hazards caused by inhaling impurities.

[0005] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0006] The anti-blocking vacuum suction cup lifting tool includes a suspension bracket, a vacuum suction cup and an air extraction device both installed on the suspension bracket. The vacuum suction cup includes

[0007] a disk body, the disk body includes a concave surface, a convex surface and a vacuum chamber. The concave surface is adjacent to the vacuum chamber and concaves inward towards the convex surface. The convex surface is away from the vacuum chamber relative to the concave surface and protrudes outward from the vacuum chamber;

[0008] The air guiding column is vertically arranged, and an air guiding chamber is provided on the top surface thereof. The air guiding chamber is in fluid communication with the air extraction device. The air guiding chamber and the air extraction device can be connected through an air guiding pipe. The bottom surface of the air guiding column is fixedly connected to the convex surface of the disc body. The air guiding chamber is in fluid communication with the vacuum chamber through at least two anti-blocking air guiding mechanisms. The air extraction device is tightly connected to the top of the air guiding column and is in fluid communication with the vacuum chamber;

[0009] The anti-blocking air guiding mechanism includes a first air guiding pipe, a second air guiding pipe, and a dust-proof cover which is arranged on the top of the concave surface of the disc body in a hollowed-out manner. One end of the first air guiding pipe is in fluid communication with the first air guiding end of the second air guiding pipe through an air guiding pipe. The other end of the first air guiding pipe is inserted into the air guiding chamber from the outside of the air guiding column. The second air guiding end of the second air guiding pipe is horizontally inserted into the vacuum chamber of the disc body and the inside of the dust-proof cover in sequence from the convex surface of the disc body. A bending portion is provided between the first air guiding end and the second air guiding end of the second air guiding pipe, and the bending angle of the bending portion is an acute angle.

[0010] For the anti-blocking vacuum suction cup lifting sling provided by the present utility model, preferably, the first air guiding pipe of the anti-blocking air guiding mechanism is detachably and tightly connected to the air guiding column.

[0011] For the anti-blocking vacuum suction cup lifting sling provided by the present utility model, preferably, the second air guiding end of the second air guiding pipe of the anti-blocking air guiding mechanism is detachably and tightly connected to the air guiding column.

[0012] For the anti-blocking vacuum suction cup lifting sling provided by the present utility model, preferably, the dust-proof cover includes an annular side surface and a mesh-shaped hollowed-out breathable bottom surface. The second air guiding end of the second air guiding pipe is inserted into the inside of the dust-proof cover from the annular side surface and is movably connected to the annular side surface.

[0013] For the anti-blocking vacuum suction cup lifting sling provided by the present utility model, preferably, the annular side surface of the dust-proof cover is provided with air holes.

[0014] For the anti-blocking vacuum suction cup lifting sling provided by the present utility model, preferably, the inner diameter of the second air guiding pipe is smaller than the diameter of the circle of the transverse section of the air guiding column.

[0015] For the anti-blocking vacuum suction cup lifting sling provided by the present utility model, preferably, the bending angle of the bending portion of the second air guiding pipe is 45°.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] The vacuum suction cup lifting sling provided by the present utility model is provided with an anti-blocking air guiding mechanism. Firstly, the anti-blocking air guiding mechanism sucks air horizontally in the vacuum chamber, and it is not easy to suck out impurities. Secondly, a dust-proof cover is provided to filter larger impurities. Then, the bending part of the second air duct reduces the passing ability of impurities. For example, long and thin needle-shaped metal impurities may penetrate the filter screen and damage the air duct between the first air duct and the second air duct. Or when the filter screen is damaged, more destructive impurities are directly sucked in and cause more serious damage to the air duct. Since the passing ability is reduced, the damage force of such impurities to the air duct is reduced, and the service life of the air duct is prolonged. At the same time, when there are more such high-risk impurities, they are likely to accumulate and form a blockage at the bending part. The blockage causes the air duct to deform, which can timely warn of safety risks. Finally, the modular design facilitates the disassembly, cleaning and replacement of the first air duct, the second air duct, and the air duct between the first air duct and the second air duct. Therefore, the vacuum suction cup lifting sling provided by the present utility model can efficiently solve the problem of safety hazards caused by sucking in impurities. Therefore, the anti-blocking vacuum suction cup lifting sling of the present utility model can efficiently solve the problem of safety hazards caused by sucking in impurities.

Detailed Embodiment

[0023] Next, in combination with the accompanying drawings of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments of the present application are only partial embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0024] Referring to Figures 1-4 , the anti-blocking vacuum suction cup lifting sling provided by the embodiment of the present utility model includes a hanging frame 1, and a vacuum suction cup 2 and an air extraction device 3 both installed on the hanging frame 1. The vacuum suction cup 2 includes

[0025] a disc body 21. The disc body 21 includes a concave surface 211, a convex surface 212 and a vacuum chamber 213. The concave surface 211 is adjacent to the vacuum chamber 213 and is recessed inwardly toward the convex surface 212. The convex surface 212 is away from the vacuum chamber 213 relative to the concave surface 211 and protrudes outward from the vacuum chamber 213.

[0026] a gas guiding column 22. The gas guiding column 22 is vertically arranged and has a gas guiding chamber 221 opened on the top surface. The gas guiding chamber 221 is in fluid communication with the air extraction device 3. The bottom surface of the gas guiding column 22 is fixedly connected to the convex surface 212 of the disc body 21. The gas guiding chamber 221 is in fluid communication with the vacuum chamber 213 through at least two anti-blocking gas guiding mechanisms 23. The air extraction device 3 is tightly connected to the top of the gas guiding column 22 and is in fluid communication with the vacuum chamber 213.

[0027] The anti-blocking gas guiding mechanism 23 includes a first gas guiding pipe 231, a second gas guiding pipe 232, and a dust-proof cover 233 which is hollow and arranged at the top of the concave surface 211 of the disc body 21. One end of the first gas guiding pipe is in fluid communication with the first gas guiding end 232a of the second gas guiding pipe 232 through a gas guiding pipe 234. The other end of the first gas guiding pipe 231 is inserted into the gas guiding chamber 221 from the outside of the gas guiding column 22. The second gas guiding end 232b of the second gas guiding pipe 232 is sequentially inserted horizontally into the vacuum chamber 213 of the disc body 21 and the inside of the dust-proof cover 233 from the convex surface 212 of the disc body 21. A bending portion 232c is provided between the first gas guiding end 232a and the second gas guiding end 232b of the second gas guiding pipe 232, and the bending angle of the bending portion 232c is an acute angle.

[0028] Specifically, the first gas guiding pipe 231 of the anti-blocking gas guiding mechanism 23 is detachably and tightly connected to the gas guiding column 22, and specifically, it can be a bolt connection.

[0029] Specifically, the second gas guiding end 232b of the second gas guiding pipe 232 of the anti-blocking gas guiding mechanism 23 is detachably and tightly connected to the gas guiding column 22, and specifically, it can be a bolt connection.

[0030] Specifically, the dust cover 233 includes an annular side surface 233a and a net-shaped and hollowed-out breathable bottom surface 233b. The second air guide end 232b of the second air guide pipe 232 is inserted into the interior of the dust cover 233 from the annular side surface 233a and is movably connected to the annular side surface 233a.

[0031] Specifically, the annular side surface 233a of the dust cover 233 is provided with air holes.

[0032] Specifically, the inner diameter of the second air guide pipe 232 is smaller than the diameter of the circle of the cross-section of the air guide column 22.

[0033] Specifically, the bending angle of the bending portion 232c of the second air guide pipe 232 is 45°. This angle can ensure the gas permeability while reducing the impurity permeability as much as possible.

[0034] For the anti-blocking vacuum suction cup lifting sling provided by the present utility model, the air in the vacuum chamber 213 of the disc body 21 is pumped out by the air extraction device 3, so that the vacuum suction cup 2 adsorbs the adsorbed object. When the air extraction device 3 pumps air, the air first passes through the dust cover 233. Since the dust cover 233 is hollowed out, gas can pass through and impurities can be isolated. Subsequently, the air sequentially passes through the second air guide pipe 232, the air guide pipe 234, the first air guide pipe 231 and the air guide chamber 221, and finally leaves the vacuum suction cup 2 and enters the air extraction device 3.

[0035] The second air guide end 232b of the second air guide pipe 232 is horizontally arranged, which can reduce the vertical suction force on the impurities, thereby reducing the entrainment of impurities. At the same time, the bending angle of the bending portion 232c of the second air guide pipe 232 is an acute angle, which can reduce the impurity permeability. Especially for the longer impurities that are not filtered by the dust cover 233, on the one hand, it buffers them, and on the other hand, when there are more such impurities, they are likely to be blocked in the bending portion 232c, or when the dust cover 233 is damaged, larger impurities are also likely to be blocked in the bending portion 232c. When the bending portion 232c is blocked, the gas permeability is poor, and the corresponding air guide pipe 234 deforms due to the pressure difference. Therefore, the bending portion 232c can not only protect the air guide pipe 234, but also facilitate timely feedback of abnormalities and reduce potential safety hazards.

[0036] The aperture of the second air guide pipe 232 is small. Compared with the direct suction of a large-aperture conduit in the normal vertical direction, it can itself reduce the inhalation of impurities. By arranging a plurality of anti-blocking air guide mechanisms 23, on the one hand, the air extraction efficiency is ensured, and on the other hand, when one of the anti-blocking air guide mechanisms 23 is blocked, the vacuum suction cup 2 as a whole can still work normally, further reducing potential safety hazards.

[0037] The anti-blocking air guiding mechanism 23 adopts a modular design, which is convenient for disassembly, cleaning and replacement. For the second air duct 232 and the air duct 234, targeted regular inspections can be carried out to efficiently prevent potential hazards.

[0038] In summary, the anti-blocking vacuum suction cup lifting sling of the present utility model can efficiently solve the problem of potential safety hazards caused by inhaled impurities.
