Description

Technical Field

[0001] The utility model relates to the technical field of industry, and particularly relates to a lifting device. Background Art

[0002] The lifting of PU thinner packaging refers to the process of hoisting and transporting packages filled with PU thinner. In this process, special lifting equipment such as cranes or hoists is required. Through load-bearing devices such as steel cables, chains or slings, packages filled with PU thinner (such as containers like barrels and cans) are safely and stably lifted from one place to another.

[0003] PU thinner packages are generally barrel-shaped structures. Existing lifting devices have problems with insecure fixation for barrel-shaped containers, which can cause the packaging barrels to roll down, resulting in economic losses and even casualties. At the same time, traditional lifting devices use clamping jaws for clamping. In case of an emergency power failure, the clamping force of the clamping jaws will decrease, reducing the safety of the lifting device. Content of the Utility Model

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0037] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field.

[0040] Lifting of PU diluent packaging refers to the process of lifting and transporting the packaging containing PU diluent. In this process, special lifting equipment, such as cranes or hoists, is required to lift the packaging (such as barrels, cans and other containers) containing PU diluent safely and stably from one place to another through load-bearing devices such as steel cables, chains or slings.

[0041] In the related art, PU diluent packaging is generally a barrel-shaped structure. The existing lifting device has the problem of loose fixation for lifting barrel-shaped containers, which may cause the packaging barrel to roll, resulting in economic losses and even casualties. At the same time, the traditional lifting device uses claws to clamp, and when encountering an emergency power outage, the clamping force of the claws will be reduced, reducing the safety of the lifting device.

[0042] To solve the problems in the related art to a certain extent, the embodiment of the present application provides a lifting device. When in use, only need to start the telescopic cylinder 21, the length of the telescopic rod 22 increases, driving the first connecting block 23 at the end of the telescopic rod 22 to move vertically downward, and then pushing the second rotating plate 25 and the third rotating plate 26, so that the second rotating plate 25 and the third rotating plate 26 reach the vertical state. At this time, the material between the clamping blocks 29 is fixed. At this time, both the second rotating plate 25 and the third rotating plate 26 are in the vertical state. At this time, even if the power is cut off, there is no force in the tilting direction between the second rotating plate 25 and the third rotating plate 26, only a relative force, that is, the position of the second connecting plate 27 is fixed. At this time, a self-locking function is formed, increasing the safety of the device. At the same time, the firmness of the device for fixing the material is increased. The outer side of the end of the first connecting plate 1 can be connected to a crane, that is, the lifting function of the device is completed.

[0043] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0044] Combined with Figures 1-4 , the embodiment of the present application provides a lifting device, including a first connecting plate 1, and further including a fixing component 2 arranged outside the first connecting plate 1. The fixing component 2 includes: a telescopic cylinder 21 installed inside the end of the first connecting plate 1; a telescopic rod 22 installed inside one end of the telescopic cylinder 21, and the telescopic rod 22 is slidably connected to the inner side of the end of the first connecting plate 1; a first connecting block 23 fixedly connected to the outer side of the end of the telescopic rod 22; a first rotating plate 24 rotatably connected to the outer side of the end of the first connecting block 23; a second rotating plate 25 rotatably connected to the inner side of one end of the first rotating plate 24; a third rotating plate 26 rotatably connected to the inner side of one end of the second rotating plate 25; a second connecting plate 27 arranged below the third rotating plate 26, and the second connecting plate 27 is rotatably connected to the outer side of the end of the third rotating plate 26; a third connecting plate 28 arranged below the second connecting plate 27; clamping blocks 29 fixedly connected to the upper surface of the third connecting plate 28 and the lower surface of the second connecting plate 27. A sliding rod 210 passes through the outer sides of the ends of the second connecting plate 27 and the third connecting plate 28, and the outer side of the end of the sliding rod 210 is fixedly connected to the lower surface of the first connecting plate 1;

[0045] By Figures 1-2It can be seen that when the device needs to be used for hoisting, the telescopic cylinder 21 is started, the telescopic rod 22 contracts, and then drives the first rotating plate 24 rotatably connected to the first connecting block 23 to move upward. At the same time, the second rotating plate 25 and the third rotating plate 26 are pulled inward through the first rotating plate 24. When the third rotating plate 26 moves inward, it will pull the second connecting plate 27 to slide in the vertical direction. At this time, the distance between the two clamping blocks 29 increases, and the staff can place the material between the two clamping blocks 29. After the placement is completed, the telescopic cylinder 21 is started again, the length of the telescopic rod 22 increases, and the first connecting block 23 at the end of the telescopic rod 22 moves vertically downward, and then pushes the second rotating plate 25 and the third rotating plate 26, so that the second rotating plate 25 and the third rotating plate 26 reach the vertical state. At this time, the material between the clamping blocks 29 is fixed. At this time, both the second rotating plate 25 and the third rotating plate 26 are in the vertical state. At this time, even if the power is cut off, there is no force in the inclined direction between the second rotating plate 25 and the third rotating plate 26, only a relative force, that is, the position of the second connecting plate 27 is fixed. At this time, a self-locking function is formed, which increases the safety of the device and at the same time increases the firmness of the device for fixing the material. The outer side of the end of the first connecting plate 1 can be connected to a crane, that is, the hoisting function of the device is completed.

[0046] In some embodiments, a clamping arm 211 is rotatably connected to the outer side of the end of the first connecting plate 1. The inner side of the end of the clamping arm 211 is rotatably connected to a fourth rotating plate 212. The inner side of the end of the fourth rotating plate 212 is rotatably connected to a second connecting block 213. A rope 214 is fixedly connected to the upper surface of the second connecting block 213.

[0047] A clamping arm 211 is rotatably connected to the outer side of the end of the first connecting plate 1. The staff can connect the rope 214 to a crane. When the staff fixes the material inside the clamping block 29 and then lifts it through the rope 214, the rope 214 will pull the second connecting block 213, and then drive the fourth rotating plate 212 to contract inward. During the process of the fourth rotating plate 212 contracting inward, it will drive the clamping arm 211 to rotate, that is, the end of the clamping arm 211 clamps the material. By the way of driving the second connecting block 213 by the rope 214 to clamp the clamping arm 211, the heavier the material is, the greater the lifting force of the rope 214 is, and the greater the force driving the clamping arm 211 to clamp is, which increases the self-adaptability of the device and at the same time further increases the firmness of fixing the material.

[0048] In some embodiments, the end of the clamping arm 211 is of an arc structure, and the end of the clamping block 29 is of an arc structure.

[0049] Through the arc-shaped structures at the ends of the clamping arms 211 and the arc-shaped structures at the ends of the clamping blocks 29, the shape of the material can be better adapted, and thus the material can be contacted more closely, increasing the stability of the material clamping. At the same time, through the double fixation of the clamping block 29 and the clamping arm 211, the possibility of the material falling is further reduced.

[0050] In some embodiments, several first anti-slip strips 215 are fixedly connected to the inner side of the end of the clamping arm 211. The material of the first anti-slip strips 215 is rubber. Several second anti-slip strips 216 are fixedly connected to the inner side of the end of the clamping block 29. The material of the second anti-slip strips 216 is rubber.

[0051] Several first anti-slip strips 215 are fixedly connected to the inner side of the end of the clamping arm 211. The material of the first anti-slip strips 215 is rubber. Several second anti-slip strips 216 are fixedly connected to the inner side of the end of the clamping block 29. The material of the second anti-slip strips 216 is rubber. Through the first anti-slip strips 215 and the second anti-slip strips 216, the friction between the material and the device can be further increased to prevent the material from falling.

[0052] In some embodiments, a sealing ring 217 is fixedly connected to the outside of the through hole opened at the end of the second connecting plate 27.

[0053] A sealing ring 217 is fixedly connected to the outside of the through hole opened at the end of the second connecting plate 27. The sealing ring 217 is in contact with the sliding rod 210. Through the sealing ring 217, dust and other sundries can be prevented from entering the gap between the second connecting plate 27 and the sliding rod 210, which may hinder the sliding of the second connecting plate 27. Through the sealing ring 217, the service life of the device can be increased.

[0054] In some embodiments, a fixing ring 218 is fixedly connected to the outside of the end of the first connecting plate 1. The fixing ring 218 is sleeved on the outer surface of the rope 214, and the fixing ring 218 is slidably connected to the rope 214.

[0055] A fixing ring 218 is fixedly connected to the outside of the end of the first connecting plate 1. Through the fixing ring 218, the position of the rope 214 can be limited, ensuring the stability of the rope 214 during the lifting process and further preventing the material from falling from the inside of the device during the lifting process.
