Description

Technical Field

[0001] This utility model belongs to the field of lifting device technology, and specifically relates to a portable lifting device and a hydrogen peroxide bath lifting system. Background Technology

[0002] In the filling and production of liquid products, hydrogen peroxide is often used to sterilize packaging materials (such as aseptic brick bags using paper-based composite materials, aseptic bags using composite aluminum foil packaging materials, or PE packaging materials). Many filling machines (such as Simply8 filling machines and TBA8 filling machines) are equipped with hydrogen peroxide tanks inside, and their structures often employ a narrow and tall jacketed heat exchange structure: the outer layer holds the sterilizing hydrogen peroxide, while the inner layer circulates the heat exchange medium (such as hot water). However, with prolonged use, the tank may leak due to corrosion; once leakage occurs, the heat exchange medium and hydrogen peroxide will mix, leading to a decrease in hydrogen peroxide concentration, severely affecting the sterilization effect and posing potential product quality risks. To avoid leakage caused by corrosion, manufacturers need to regularly disassemble, inspect, and verify the hydrogen peroxide tank and replace it as needed. Due to the high weight and narrow installation space of the hydrogen peroxide tank, it is inconvenient to move, making disassembly, inspection, or replacement difficult and inconvenient.

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The technical solutions of the present invention will be further described below with reference to the accompanying drawings of the embodiments. The present invention is not limited to the specific embodiments described below.

[0022] It should be understood that the same or similar reference numerals in the accompanying drawings of the embodiments correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "front," "rear," "left," "right," "top," and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0023] Please refer to Figures 1 to 4 This utility model provides a portable lifting device 10, including... The base 100 has a maximum length of 40-60cm and a maximum width of 15-30cm. Its compact size facilitates access to narrow spaces. The dimensions are adaptable to confined spaces. In practice, the accessible width on-site is ≤40cm, the lifting height is ≤80cm, and the maximum length is ≤70cm.

[0024] A pair of linkage support mechanisms 200 are arranged in a mirror image on both sides of the base 100. One end of each linkage support mechanism 200 is rotatably connected to the base 100, and the linkage support mechanism 200 performs an upward support movement in the vertical direction. With the pair of linkage support mechanisms 200, during the upward support process, the pair of linkage support mechanisms 200 rise or fall simultaneously, making the upper support plane more evenly stressed.

[0025] A drive mechanism 300 is rotatably mounted on the base 100. The drive end of the drive mechanism 300 is rotatably connected to the connecting rod supporting mechanism 200, and is used to push the connecting rod supporting mechanism 200 to perform an upward supporting movement. The drive mechanism 300 can be selected from devices with pushing functions such as drive cylinders, jacks, and electric actuators. Preferably, the drive mechanism is a drive cylinder.

[0026] The base 100 is moved by a movable wheel 400 disposed on the lower end face of the base base.

[0027] A support platform 500 is provided, which is rotatably connected to the other end of the rod-lifting mechanism. By using a pair of connecting rod-lifting mechanisms 200 to push the support platform 500 up or down, the support platform 500 becomes more stable. Furthermore, because the connecting rod-lifting mechanisms 200 are rotatably connected to the support platform 500, the pair of connecting rod-lifting mechanisms 200 can maintain the stability of the support platform 500. If only one connecting rod-lifting mechanism 200 is provided, the support platform 500 is prone to swaying left and right.

[0028] Specific movement process: The operator pushes the portable lifting device 10 to move it into a narrow space (a narrow space refers to an area that is inconvenient for personnel to enter, and even if personnel enter, it is difficult to move or exert force), and positions it below the device to be moved. The device to be moved may include a heavy box, etc. The operator operates the drive mechanism 300 from outside the narrow space, or enters the narrow space to operate the drive mechanism 300 (the space is relatively small, making it inconvenient for personnel to move heavy objects, but the drive mechanism 300 can be operated). The drive mechanism 300 pushes the connecting rod support mechanism 200 upward, supporting it to the bottom surface of the device to provide support. The operator then pushes the portable lifting device 10 and the device to be moved out of the narrow space. The same steps are used to move and lift the device when it is installed in a narrow space. Furthermore, since only small drive mechanisms 300 (such as small drive cylinders or small jacks) can be used in confined spaces, the short stroke of the small drive mechanism 300 makes it difficult to support the bottom of the device being moved. However, by using a pair of connecting rod lifting mechanisms 200 in conjunction with the drive mechanism 300, the drive mechanism 300 can push the connecting rod lifting mechanisms 200 to rise a greater distance, thus compensating for the short stroke of the drive mechanism 300 when used alone.

[0029] The portable lifting device 10 is small in size and easy to move, which is conducive to moving and lifting in narrow spaces. It can quickly move heavy objects in narrow spaces and improve the convenience of moving heavy objects. At the same time, it does not require manual lifting of heavy objects. Only manual assistance is needed to move heavy objects with the help of the portable lifting device 10, which saves more manpower. Moreover, it is safer for operators to work in narrow spaces.

[0030] In one possible embodiment, the linkage support mechanism 200 includes a pair of support arms 210 and a pair of support seats 220. The pair of support arms 210 are symmetrically arranged, and the support seats 220 are rotatably connected to the support arms 210. One support seat 220 is located above the support arm 210, and the other support seat 220 is located below the support arm 210. The pair of support arms 210 mainly provide support and help maintain balance. One support seat 220 is connected to the upper support platform 500, and the other support seat 220 is connected to the lower base 100. The support seats 220 are mainly used to support the support arms 210 and maintain the balance of the support arms 210, so that the support arms 210 remain in a vertical direction.

[0031] In a preferred embodiment, the support arm 210 includes a first supporting arm 211, a second supporting arm 212, and a first rotating screw 213. One end of the first supporting arm 211 is rotatably connected to the upper support base 220, and one end of the second supporting arm 212 is rotatably connected to the lower support base 220. The first supporting arm 211 and the second supporting arm 212 are rotatably connected via the first rotating screw 213, and the second supporting arm 212 is rotatably connected to the drive mechanism 300. Specifically, the first supporting arm 211 has a first through hole, and the second supporting arm 212 has a second through hole. One end of the first supporting arm 211 and one end of the second supporting arm 212 are mutually positioned and aligned. The first rotating screw 213 passes through the first and second through holes, and both ends of the rotating screw are locked by nuts, thereby enabling the first supporting arm 211 and the second supporting arm 212 to rotate around the first rotating screw 213.

[0032] In a preferred embodiment, the support base 220 includes a support base plate 221, a support body 222, and a support pin 223. The support base is horizontally arranged, and the support body 222 is disposed on the support base plate 221. A pair of support arms 210 are rotatably connected to the support body 222 via the support pin 223. Specifically, the support body 222 has a third through hole. Since there is a pair of support arms 210, the pair of first supporting arms 211 are mutually limited and engaged, and the first through holes of the pair of first supporting arms 211 are aligned. At the same time, the first through hole aligns with the three through hole of the support body 222. The support pin 223 passes through the first through hole and the third through hole, and the two ends of the support pin 223 are locked by pins, thereby allowing the pair of first supporting arms 211 to rotate around the support pin 223. Similarly, the second supporting arms 212 are connected in the same way, allowing the pair of second supporting arms 212 to rotate around the support pin 223. Specifically, the support base plate 221 and the support seat body 222 are connected by bolts and nuts.

[0033] Further description is needed regarding the upward and downward movement of the first support arm 211 and the second support arm 212: the drive end of the drive mechanism 300 extends, pushing the second support arm 212. The second support arm 212 rotates around the support pin 223, and the pair of second support arms 212 move closer to each other. The second support arm 212 rotates in the vertical direction, and the first support arm 211 and the second support arm 212 gradually open up, rotating in a direction approaching 180°, which in turn pushes the first support arm 211 to rotate in the vertical direction. As the first support arm 211 and the second support arm 212 rotate in the vertical direction, the support platform 500 is pushed upward. During the process of the drive end of the drive mechanism 300 pushing the second support arm 212, since the second support arm 212 is rotatably connected to the drive mechanism 300, the drive end of the drive mechanism 300 rotates along with the rotation of the second support arm 212.

[0034] In a preferred embodiment, the linkage support mechanism 200 further includes a limiting screw 230. A shuttle hole is provided in the connection area between the first support arm 211 and the second support arm 212. The limiting screw 230 passes through the shuttle hole and extends to both sides of the pair of support arms 210. When the linkage support mechanism 200 rises to a preset height, the limiting nut on the limiting screw 230 is turned to lock the linkage support mechanism 200, ensuring its stability. Simultaneously, the maximum length of the limiting screw 230 is equal to the maximum width of the pair of support arms 210 when open, effectively limiting the excessive opening of the pair of support arms 210 and preventing excessive load on the first rotating screw 213.

[0035] In one possible embodiment, the drive mechanism 300 includes a cylinder assembly 310 and a pressure regulator 320. The cylinder assembly 310 is rotatably mounted on the base 100, and the pressure regulator 320 is connected to the cylinder assembly 310. The pressure regulator 320 is used to control the extension length of the cylinder assembly 310. The pressure regulator 320 is an existing device; see the section on pressure regulator 320 in cylinder push stroke. The pressure regulator 320 allows for relatively precise control of the extension length of the cylinder assembly 310, thereby controlling the lifting height of the connecting rod lifting mechanism 200.

[0036] In a preferred embodiment, see Figure 3The cylinder assembly 310 includes a cylinder body 311, an angle adjustment seat 312, and a hinge seat 313. The cylinder body 311 is connected to the pressure regulator 320. The angle adjustment seat 312 is mounted on the base 100 and is connected to the cylinder body 311. It is used to adjust the included angle between the cylinder body 311 and the base 100 to a preset angle. One end of the hinge seat 313 is connected to the cylinder body 311, and the hinge seat 313 is connected to the connecting rod support mechanism 200. The angle adjustment seat 312 is fixed to the base 100 by bolts and nuts. The angle of the angle adjustment seat 312 can adjust the rotation angle of the cylinder body 311. Specifically, it can be adjusted by rotating a ratchet or by setting a wedge pin at the bottom of the cylinder body 311. Both of these angle adjustment methods are convenient and can ensure that the cylinder body 311 pushes perpendicularly to the second lifting arm 212 in the initial pushing state, which is beneficial to pushing the second lifting arm 212 to move. One end of the hinge seat 313 is connected to the driving end of the cylinder body 311, and the other end is connected to the second lifting arm 212. The hinge seat 313 can realize hinged rotation, that is, the driving end of the cylinder body 311 and the second lifting arm 212 are rotatably connected through the hinge seat 313. As the second lifting arm 212 rotates, the hinge seat 313 can also adaptively rotate.

[0037] Specifically, the cylinder body 311 is an existing push cylinder, and the specific structure of the push cylinder will not be described in detail.

[0038] Specifically, the hinge seat 313 is a double-eared joint seat, such as... Figure 3 The hinge seat 313 can maintain a stable connection with the drive end of the cylinder body 311 and can also rotate.

[0039] In a preferred embodiment, the movable wheel 400 includes a steering knuckle 410 and a wheel body 420. The steering knuckle 410 is rotatably disposed below the base 100, and the wheel body 420 is mounted on the steering knuckle 410. By providing the steering knuckle 410, the movable wheel 400 can move in any direction during movement, which is beneficial for the portable lifting device 10 to move in narrow spaces.

[0040] In a preferred embodiment, the base 100 includes a pair of crossbars 110 and a push plate 120. A pair of connecting rod support mechanisms 200 are mounted on the crossbars 110, and the pair of crossbars are fixedly mounted on the push plate 120. A preset distance is reserved between the pair of crossbars, which is consistent with the width of the support base plate 221. The crossbars are connected to the support base by welding. The pair of crossbars 110 can reduce the weight of the base 100. A push handle 121 is detachably provided on the push plate 120. When the narrow space is limited and the push handle 121 cannot support the entry, the push handle 121 is removed from the push plate 120, and the push plate 120 is manually pushed into the narrow space.

[0041] This utility model provides a hydrogen peroxide bath lifting system, see [link / reference] Figures 1 to 3 The system includes a portable lifting device 10, a hydrogen peroxide bath 20, and a level 30. The bottom of the hydrogen peroxide bath 20 is in contact with the support platform 500 of the portable lifting device 10, and the level 30 is mounted on the support platform 500. The portable lifting device 10 is suitable for replacing and installing the hydrogen peroxide bath 20. When the portable lifting device 10 is below the hydrogen peroxide bath 20, it rises, contacts the bottom of the hydrogen peroxide bath 20, and applies force. Moving the portable lifting device 10 removes the hydrogen peroxide bath 20 from confined spaces. Similarly, the portable lifting device 10 allows for quick installation of the hydrogen peroxide bath 20 in confined spaces, improving installation efficiency. By observing the level 30, the system determines whether the support platform 500 is level, thus ensuring that the support platform 500 is in contact with the bottom of the hydrogen peroxide bath 20.

[0042] In a preferred embodiment, a limiting plate 510 is provided on the upper surface of the support platform 500. The limiting plate 510 is used to limit and engage the hydrogen peroxide bath 20, preventing the hydrogen peroxide bath 20 from slipping off the support platform 500 when the portable lifting device 10 is pushed.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
