Description

Technical Field

[0001] The present invention relates to an auxiliary device for loading and unloading equipment, which is used for loading and unloading equipment with a certain weight, and particularly relates to an auxiliary device for loading and unloading a drum. Background Art

[0002] In the prior art, a high-speed tubular centrifuge consists of a sliding bearing assembly, a drum assembly, a liquid accumulation tray assembly, a machine head assembly, a fuselage, etc.

[0003] In such a high-speed tubular centrifuge, materials are injected into the drum from the bottom feed port. Under the action of a strong centrifugal force, the liquid is forced to perform a stratification movement. The light liquid is at the center of the drum and flows to the drum to be recovered through the liquid accumulation tray. The heavy solid is thrown onto the inner wall of the drum and is manually unloaded after the machine stops.

[0004] During unloading, the drum needs to be disassembled and transported. And since the opening of the drum machine is generally arranged at the bottom, after disassembly, the drum needs to be horizontally placed on a fixed workbench to be unloaded and cleaned.

[0005] Generally, the weight of the drum machine is about 30 kg - 40 kg. And since it is a valuable equipment, it should not be disassembled and transported in a simple and rough manner. Moreover, since there are protruding parts below the drum, two people need to operate simultaneously. First, the drum needs to be vertically lifted upward by a certain distance before it can be removed. In addition, since the liquid accumulation tray assembly is sleeved outside the drum. Therefore, the liquid accumulation tray assembly must be taken out from the gap on the head of the drum first (at this time, a protective bushing on the upper part must be removed to form enough gap). And due to the weight and characteristics of the drum itself, even two operators still need to operate carefully.

[0006] Currently, there is an auxiliary device for loading and unloading disclosed in the prior art (see the bulletin of Chinese Patent CN205887211U), which is used for loading and unloading a tubular centrifuge through a vertical plate, two loading and unloading plates arranged on the vertical plate, a bottom plate, and flexible rollers arranged on the bottom plate.

[0007] However, this auxiliary device for loading and unloading still has the following problems:

[0008] 1. The lifting of the drum is still laborious and has a large movement range;

[0009] 2. It does not have height adjustability for centrifuges at different height positions;

[0010] 3. It does not have synchronous operation for the liquid accumulation tray assembly.

[0011] Therefore, due to the above three problems, there are still issues such as complex and laborious operations in drum disassembly, as well as equipment damage caused by careless operations. This results in a waste of labor and affects production efficiency at the same time. Summary of the Invention

[0012] Problems to be Solved by the Invention:

[0013] In view of the above problems, the purpose of the present invention is to provide an equipment loading and unloading auxiliary device that can safely and stably disassemble and transport a drum with only one operator and relatively little physical effort.

[0014] Means for Solving the Problems:

[0015] The equipment loading and unloading auxiliary device according to the present invention includes a loading and unloading unit having a main rod and a rotatable claw portion provided on the main rod; and a claw portion adjusting device for adjusting the rotation angle of the claw portion.

[0016] According to the above structure, in the past, two operators were required to jointly lift a heavy drum vertically upward by a certain distance before disassembly. However, with the equipment loading and unloading auxiliary device of the present invention, only one operator can complete the disassembly and transportation of the drum, thus saving labor costs.

[0017] Preferably, the claw portion adjusting device includes: an eccentric wheel provided on the main rod of the loading and unloading unit in such a way that its outer circumference contacts the rear end of the claw portion; and a grip rod provided on the outer circumference of the eccentric wheel.

[0018] According to the above structure, not only is the manual disassembly that originally required two people reduced to one person, but also this one operator does not need to expend too much physical effort. By applying a certain force to the device, the disassembly can be easily carried out through the lever principle and the eccentric structure, thereby reducing the labor intensity of the operator.

[0019] As an embodiment of the equipment loading and unloading auxiliary device of the present invention, it may further include a hinge device having: at least one hinge arm; and hinge fasteners connected to both ends of the hinge arm.

[0020] According to the above structure, the equipment loading and unloading auxiliary device can be directly applied to the outside of a centrifuge or a drum box to complete the loading and unloading of the drum, with simple operation and space saving, and is usually applicable to workshops with a small working space.

[0021] As another embodiment of the equipment loading and unloading auxiliary device of the present invention, it may also be equipped with a moving unit for moving the equipment device auxiliary device.

[0022] As an implementation of the above-mentioned mobile unit, it can be that the mobile unit has: a pair of left and right vertical frames; at least one connecting frame for connecting the pair of left and right vertical frames; and a plurality of rollers provided at the bottom of the vertical frames.

[0023] As another implementation of the above-mentioned mobile unit, it can also be that the mobile unit has: a bottom frame; a structural frame provided above the bottom frame; and a plurality of rollers provided below the bottom frame.

[0024] According to the above structure, compared with the hinge device that directly uses the equipment loading and unloading auxiliary device on the outer side of the centrifuge or the drum machine box body, the mobile unit adopting this structure can improve the flexibility of the present invention and can generally be used in workshops with a larger working space.

[0025] Preferably, it further includes a lifting device, and the lifting device has: a guide rod vertically fixed on the bottom frame of the mobile unit; and a guide cylinder rotatably connected to the main rod of the loading and unloading unit and capable of moving up and down along the guide rod.

[0026] According to the above structure, since there are differences in the height of the natural storage position of the centrifuge drum in the market, through this lifting structure, even in mass production, it can be applicable to drums at different height positions in each factory, thereby improving the industrial applicability of the device of the present invention.

[0027] Preferably, it further includes a telescopic device, and the telescopic device has: a pressure cylinder rotatably connected to the mobile unit; and a piston rod rotatably connected to the loading and unloading unit and capable of freely telescoping along the pressure cylinder.

[0028] According to the above structure, combined with the above-mentioned lifting device, the loading and unloading unit can be freely rotated to a horizontal position. Therefore, when taking or cleaning the drum, there is no need to manually lift and hold it to the workbench. The drum can be directly rotated to a horizontal state on the equipment loading and unloading auxiliary device of the present invention, so as to open the opening below the drum for taking and cleaning materials, thereby not only saving labor costs and consumption, but also improving work efficiency.

[0029] Preferably, a limiting member is provided on the lower side of the main rod of the loading and unloading unit.

[0030] According to the above structure, since a drum bracket is provided on the lower side of the main rod, it can prevent the internal loss caused by the shaking of the drum and the falling off caused by the shaking when the device of the present invention moves while clamping the drum.

[0031] Preferably, a baffle is provided at the lower position of the connection between the main rod of the loading and unloading unit and the guide cylinder of the lifting device.

[0032] According to the above structure, since a baffle is provided on the lower end side of the main rod, the main rod itself has a certain slope, which can prevent the drum from falling off during the handling and moving process, thus improving the safety during its use.

[0033] Preferably, the front end of the claw part has an anti-slip lug protruding upward and a fitting positioning lug protruding outward on both sides.

[0034] According to the above structure, the front end of the claw part has an anti-slip lug protruding upward. Therefore, when the claw part is lifted upward by a certain angle through the claw part adjusting device, problems such as the clamped object falling off will not occur, thus further improving the safety during the use of the device. At the same time, since the front end of the claw part also has a fitting positioning lug protruding outward on both sides, during the use process, the liquid collecting tray above the drum can be taken out together, further improving the working efficiency.

[0035] Advantages of the invention:

[0036] 1. Only one operator is required to complete the disassembly, assembly and handling of the drum, saving labor costs in terms of the number of operators.

[0037] 2. This single operator only needs very little physical strength to disassemble the drum, reducing the labor intensity in terms of the physical strength of the operator.

[0038] 3. The synchronous installation and removal of the drum and the liquid collecting tray assembly are completed, improving the working efficiency.

[0039] 4. There is no need to repeatedly move the heavy equipment to the operating table, and it can be directly rotated to the horizontal position for subsequent work, further improving the working efficiency.

[0040] 5. The main rod rotated to the horizontal position is supported by the structural frame of the moving unit, and the device will not be damaged due to the excessive weight of the clamped object, having a relatively high service life.

[0041] 6. It is equipped with a lifting device, so it can be correspondingly arranged for drums at different heights, improving the industrial applicability.

[0042] 7. The main rod has a certain slope and a drum bracket, thus ensuring that the clamped object will not fall off due to the uneven road surface during the handling process and internal damage during the shaking of the equipment. Therefore, the present invention has relatively high safety during the use process.

[0043] 8. It is designed through a simple mechanical structure, without the need for precision equipment, etc., and the manufacturing cost is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

[0089] Hereinafter, with reference to the accompanying drawings, an implementation mode of the present invention will be described.

[0090] <First Embodiment>

[0091] As Figure 1 and Figure 2As shown in the figure, the equipment loading and unloading auxiliary device involved in the present invention has a loading and unloading unit 1 in the shape of a roughly cuboid, a claw adjusting device 3 for adjusting the angle formed by the claw 12 and the main rod 11 in the loading and unloading unit 1, and a hinge device 6 for rotatably fixing the loading and unloading unit 1 to the outside of the centrifuge or the drum box body.

[0092] <Loading and unloading unit 1>

[0093] The loading and unloading unit 1 has a main rod 11, a claw 12 provided on the upper end side of the main rod 11 and rotatable within a certain angle range in the vertical direction, and a drum bracket 13 provided on the lower end side of the main rod 11 for preventing (restricting) the swaying below the drum.

[0094] The main rod 11 is generally in the shape of a hollow cuboid, but is not limited thereto. The main rod 11 is mainly used for supporting, so it can also be formed into a cylindrical shape, a trapezoidal shape, etc. according to needs, and it does not have to be a hollow structure, and can also be a solid structure.

[0095] At the upper rear side of the main rod 11 where the claw 12 is located, a claw adjusting device 3 for adjusting the angle of the claw 12 is provided. Through this claw adjusting device 3, the angle formed by the claw 12 and the main rod 11 can be adjusted.

[0096] The main rod 11 is rotatably fixed to the outside of the drum box body through the hinge device 6. Through this hinge device 6, the loading and unloading unit can rotate within a certain angle in the horizontal direction (transverse).

[0097] <Claw 12>

[0098] The claw 12 adopted by the equipment loading and unloading auxiliary device involved in the present invention is as Figure 4 and Figure 5 shown. The claw 12 has a tip bearing 122 extending backward to the rear side of the main rod 11, and its front section bifurcates to both sides and is formed into a fork 121 with a length exceeding the drum center line as Figure 7 shown.

[0099] The tip of the fork 121 has an anti-slip lug 123 protruding upward. When the fork 121 of the claw 12 is lifted vertically upward through the following claw adjusting device 3, the drum is lifted upward by the anti-slip lug 123 on the fork 121. When the protruding part at the bottom of the drum is disengaged from the engaging device and becomes in a state where it can be transported, since the drum center line is behind, the top of the drum naturally tilts backward, and thus the whole forms a certain slope. With this structure, the equipment loading and unloading auxiliary device involved in the present invention will not cause the drum to fall forward due to bumps caused by uneven roads during the transportation of the clamped drum.

[0100] Meanwhile, the tip of the fork bracket 121 also has a fitting positioning lug 124 protruding outward. When disassembling the drum, it is usually necessary to first disassemble the drum and the liquid accumulation tray as a whole and then remove the liquid accumulation tray. Therefore, as Figure 6 shown, through this fitting positioning lug 124 of the present invention, the integral disassembly of the drum and the liquid accumulation tray is realized.

[0101] However, the structure of the claw part 12 is not limited to this type and can be freely replaced or customized according to actual needs. For example, it can be replaced with a claw part having the function of adjusting the fork bracket spacing, or formed into a fork bracket claw part with a square clamping opening, etc.

[0102] <Claw part adjusting device 3>

[0103] A claw part adjusting device 3 is also provided at the rear side of the upper end of the main rod 11. The claw part adjusting device 3 adopted by the present invention, as Figure 4 shown, adopts an eccentric structure. Specifically, it has an eccentric wheel 31 provided at the rear side of the upper end of the main rod 11. The outer periphery of the eccentric wheel 31 is closely attached to the tip bearing 122 at the rear side of the claw part, and a grip rod 32 is also provided on the outer peripheral surface. When in use, by means of different center distances of the eccentric wheel, the height of the fork bracket 121 can be adjusted. At the same time, since the claw part 12 is connected to the main rod 11 through a pin structure, a lever structure is formed, and the height of the fork bracket 121 is inversely proportional to the tip bearing 122, so that the rotation angle of the front end of the claw part can be freely adjusted through this eccentric structure.

[0104] The claw part adjusting device 3 of the present invention adopts an eccentric lever structure, and its advantages are: compact structure and no need for large-span actions. However, it is not limited to this eccentric lever structure. In the present invention, the drum in the centrifuge is used as the main object for loading and unloading. Based on the characteristics of the drum, since there is a protruding part below the drum, when extracting the drum from the drum box or unloading it from the centrifuge, it is necessary to lift the drum vertically upward by a certain distance to break away from the restraint of the sliding bearing assembly before it can be freely carried away. Therefore, although the present invention adopts an eccentric structure and the lever principle to control and adjust the rotation of the claw part 12 on the main rod 11, as long as it can freely control the rotation angle of the claw part 12 as in the purpose of the present invention, it can be replaced. Therefore, the mechanical structure of the claw part adjusting device 3 is not particularly limited, and as long as it is a structure that satisfies the purpose of adjusting the rotation of the claw part 12, the technical effects of the present invention can be achieved.

[0105] <Hinge device 6>

[0106] As described above, the loading and unloading unit 1 is rotatably fixed to the outside of the drum casing by a hinge device 6 and is configured to be rotatable at a certain angle in the horizontal direction (lateral direction). The hinge device 6 is composed of a pair of upper and lower substantially plate-shaped hinge arms 61, and hinge fasteners 62 are rotatably connected to both ends of the hinge arms 61 through a pin structure. The hinge fasteners 62 have a plurality of holes, and the holes can be fixed to the outside of the drum casing and the rear side of the main rod 11 by screws and nuts.

[0107] That is, the main rod 11 and the drum casing are fixed to the hinge fasteners 62, and the hinge fasteners 62 are connected to the hinge arms 61 through a pin structure. Therefore, the main rod 11 is configured to be rotatable relative to the drum casing.

[0108] The hinge device 6 is not limited to the above structure. For example, in this embodiment, the hinge device 6 has a pair of upper and lower hinge arms 61, but multiple hinge arms can also be added to further strengthen it. Additionally, the hinge arms 61 are not limited to plate-shaped bodies and can also be cylindrical bodies, etc. The fixing form of the hinge fasteners 62 fixed to the drum casing and the outside of the centrifuge is not limited to the screw and nut structure and can also be integral welding, etc. The shape of the hinge fasteners 62 is not limited to the illustrated flat cuboid shape and can also be trapezoidal, disc-shaped, etc.

[0109] <Usage method>

[0110] The installation method of the equipment loading and unloading auxiliary device of this embodiment is to fix one end of the hinge device 6 to the rear side of the main rod 11 and the other end to the outside of the drum casing or the centrifuge through a screw and nut structure. Generally speaking, only the first installation is required. Since the overall structure of the equipment loading and unloading auxiliary device of this embodiment is relatively small and does not occupy too much space, repeated disassembly is not required after the first installation.

[0111] During use, as Figure 3As shown, only one operator is required. First, adjust the eccentric wheel 31 to rotate until the distance to the tip bearing 122 is the minimum. Then, rotate the main rod 11 by hand to align the fork frame 121 of the claw 12 with the appearance difference below the protruding part of the drum. Continue to rotate to fit the arc part of the fork frame 121 of the claw 12 with the arc of the drum. By pulling the handle 32 of the eccentric wheel 31, the distance between the center of the rotating eccentric wheel 31 and the tip bearing 122 of the claw 12 is the maximum. In the process of pulling the eccentric wheel 31, the fork frame 121 of the claw 12 is slowly lifted upward, and through the anti-slip lug 123 protruding upward at the front end of the fork frame 121, the clamped drum is lifted vertically upward until the bottom of the drum is free from the constraint of the sliding bearing assembly, forming a state that can be moved away. At the same time, due to the role of the accessory positioning lug 124 at the front end of the fork frame 121, the liquid accumulation tray above the drum is lifted together. As the fork frame 121 is lifted up, the anti-skid lug 123 naturally hooks the protruding part of the drum, ensuring that the drum will not slide forward and fall off during the subsequent movement.

[0112] <Implementation Effect>

[0113] According to the structure of the first embodiment, since the rotatable claw 12 and the claw adjusting device 3 for adjusting the rotation angle of the claw 12 are provided, the drum can be mounted and dismounted.

[0114] Since the equipment loading and unloading auxiliary device of this structure is fixed at a certain place by the hinge device 6, it is usually suitable for factories with small working space. However, for some factories with large working space and the need to transport the disassembled drum, the present invention can realize the transportation of the drum by adding a moving unit 2. Specifically, the following Figures 8 to 9 A second embodiment of the equipment loading and unloading assisting device of the present invention will be described in detail.

[0115] <Second Embodiment>

[0116] The equipment loading and unloading auxiliary device in this embodiment is different from the first embodiment in which the loading and unloading unit 1 is fixed at a certain place to load and unload the drum. The equipment loading and unloading auxiliary device in this embodiment can freely carry the disassembled drum by adding a moving unit 2. The structure of this second embodiment that is different from the first embodiment is described in detail below.

[0117] <Mobile Unit 2>

[0118] The mobile unit 2 in this embodiment is as shown in the attached Figure 8As shown in the figure, there are a pair of left and right vertical stands 26. The stands 26 are connected by a pair of upper and lower first connecting frames 27 and second connecting frames 28, thus forming a structure in a roughly trapezoidal shape. The upper ends of the stands 26 are bent laterally backward to form handrails 25, and a pair of left and right rollers 23 are provided at the lower ends thereof through roller brackets 29.

[0119] <Loading and unloading unit 1>

[0120] The loading and unloading unit 1 in this embodiment is different from the main rod 11 that is integrally formed in a long rod state in the first embodiment. It has a pair of upper and lower main rods 11, and the pair of upper and lower main rods 11 are respectively vertically arranged on the first connecting frame 27 and the second connecting frame 28 in the above-mentioned moving unit 2.

[0121] Among them, on the main rod 11 located on the first connecting frame 27, a claw part 12 that can rotate within a certain angle is provided, and on the main rod 11 located on the second connecting frame 28, a drum bracket 13 is fixedly arranged.

[0122] In addition, at a position above the claw part 12 in the rear side of the main rod 11 located on the first connecting frame 28, a claw part adjusting device 3 is provided. The claw part adjusting device has an eccentric wheel 31 and a grip rod 32 in the same manner as in the above-mentioned first embodiment. Therefore, the claw part adjusting device 3 in this embodiment can also achieve the same technical effect as in the above-mentioned first embodiment, and adjust the angle formed by the claw part 12 and the main rod 11.

[0123] <Usage method>

[0124] The equipment loading and unloading auxiliary device in this embodiment is different from the above-mentioned first embodiment and does not need to be installed and fixed, and can move freely through the bottom rollers. Therefore, when in use, first move the equipment loading and unloading auxiliary device to the drum, and then, in the same manner as in the above-mentioned first embodiment, clamp the drum through the claw part 12, adjust the angle of the claw part 12 through the claw part adjusting device 3, so as to lift the device upward to form a state where it can be carried away. Then, through the rollers, the clamped drum can be carried and moved.

[0125] <Implementation effect>

[0126] Through the structure of the second embodiment, not only can the same technical effects as in the above-mentioned first embodiment be achieved, but also the equipment loading and unloading auxiliary device of the present invention can be freely moved and placed, and after the drum is disassembled, the drum can be freely carried. Therefore, this implementation device is suitable for factories with relatively large working spaces and the operation requirement of carrying the disassembled drum.

[0127] However, generally speaking, after the drum is disassembled, it needs to be rotated to the horizontal position for material taking and cleaning. Therefore, the equipment loading and unloading auxiliary device of the present invention also has a third embodiment to meet this operation requirement.

[0128] <Third Embodiment>

[0129] The equipment loading and unloading auxiliary device in this embodiment is different from the above-mentioned first and second embodiments. It can not only disassemble the drum and freely transport the drum, but also directly rotate the drum to the horizontal position, so as to directly take materials and clean the drum.

[0130] Therefore, in order to understand the equipment loading and unloading auxiliary device in this embodiment in detail and clearly, hereinafter, with reference to Figures 10 to 12 , each component will be described in detail again.

[0131] As Figure 10 and Figure 11 shown, the equipment loading and unloading auxiliary device in this embodiment includes: a loading and unloading unit 1, a moving unit 2, a claw adjusting device 3, a lifting device 4, and a telescopic device 5.

[0132] <Loading and Unloading Unit 1>

[0133] The loading and unloading unit 1 in this embodiment, similar to the above-mentioned first embodiment, has a main rod 11 that is generally a hollow cuboid. The upper end side of the main rod 11 has a claw part 12 connected by a pin structure, and a claw adjusting device 3 is arranged at the rear side of the upper end of the main rod 11. In addition, in addition to the claw part 12, a drum bracket 13 for preventing the drum from shaking is provided at the lower end side of the main rod 11.

[0134] The lower end of the main rod 11 is connected to the guide cylinder 42 in the lifting device 4 through a pin structure 14. The guide cylinder 42 is sleeved around the outer periphery of the guide rod 41 in a freely liftable manner, and the guide rod 41 is vertically fixed on the front side of the bottom frame 21 of the moving unit 2. Therefore, due to the structure of the lifting device 4, the main rod 11 is in a state of being rotatable and vertically movable relative to the moving unit 2.

[0135] In addition, the rear side of the main rod 11 is also connected to the piston rod 52 of the telescopic device 5 through a pin structure. The piston rod 52 can freely extend and retract in the pressure cylinder 51, and the pressure cylinder 51 is connected to the structural frame 22 of the following moving unit 2 through a rotatable pin. Therefore, due to the structure of the telescopic unit 5, the main rod 11 can freely adjust the distance and angle relative to the moving unit 2.

[0136] In addition, between the main rod 11 and the guide rod 41, and at a position below the pin structure where the main rod 11 is connected to the guide cylinder 42, a baffle 15 is provided. Through the baffle 15, a certain slope is formed between the main rod 11 and the bottom frame of the moving unit 1, so as to prevent the clamped drum from falling off during use.

[0137] <Moving unit 2>

[0138] The moving unit 2 in this embodiment has a bottom frame 21, and a structural frame 22 is provided above the bottom frame 21. The function of the structural frame 22 is that when the loading and unloading unit 1 rotates to the horizontal position, the structural frame 22 has a certain supporting effect on the loading and unloading unit 1. At the same time, it has a certain weight by itself and is arranged on the bottom frame to prevent the device of the present invention from tipping forward due to excessive weight in the front when clamping a drum. At the same time, a storage board can also be placed on the bottom frame 11 to form a storage space, and some mechanical tools can be placed on the board.

[0139] As described above, the guide rod 41 of the lifting device 4 is fixedly provided on the front side of the bottom frame 21, and the main rod 11 and the moving unit 2 are formed into a state of being rotatable and vertically liftable through the lifting device. The upper surface of the front side of the structural frame 22 is connected to the pressure cylinder 51 of the telescopic device 5 through a pin structure. Therefore, the main rod 11 and the moving unit 2 are formed into a state of being able to freely adjust the angle and distance through the telescopic device 5.

[0140] In addition, the moving unit 2 in this implementation unit also has some other possible deformations. For example, a handrail for helping the device of the present invention to move is provided on the rear side of the structural frame 21. In addition, the structure of the moving unit 2 does not need to be exactly as shown in this drawing. It can be integrally formed into a trapezoidal shape, or it can be a cube, a cuboid, an ellipsoid, etc. Therefore, the drawing cannot be used as a basis for limiting the structure of the moving unit of the present invention.

[0141] <Claw adjusting device 3>

[0142] In this embodiment, the claw adjusting device 3 still adopts the same eccentric structure as the first embodiment, but it can also be a structure with a gear and a locking part arranged between the claw 12 and the main rod 11 to adjust the angle between the claw 12 and the main rod 11. Of course, it can also be a structure in which the tip bearing 122 of the claw 12 is greatly extended or a long rod is provided at the tip bearing 122, and it is chain-connected to the rear side of the structural frame 22, and the distance between the tip bearing 122 and the structural frame 22 is adjusted by adding rollers to adjust the angle between the claw 12 and the main rod 11.

[0143] <Lifting device 4>

[0144] The lifting device 4 in this embodiment has a guide rod 41 vertically and fixedly arranged on the front side of the bottom frame 21 of the moving unit 2, and a guide cylinder 42 that can freely move up and down along the guide rod 41. As described above, the guide cylinder 421 is rotatably connected to the main rod 11 of the loading and unloading unit 1 through a pin structure. Therefore, with this structure, the main rod 11 of the loading and unloading unit 1 can freely rotate and move up and down relative to the moving unit 2 within the required range.

[0145] Through the lifting device 4 of the present invention, not only can it be used for drums placed at different heights, but also through the lifting device 4, the loading and unloading unit 1 can be rotated to a horizontal position and supported by the structural frame 22 of the moving unit 2. However, in order to further ensure the safety of the rotation process and further reduce manpower consumption, the lifting device 4 of the device of the present invention is combined with the following telescopic device 5, which can further ensure that the loading and unloading unit 1 holding the drum can be smoothly, easily and safely rotated to the horizontal position.

[0146] <Telescopic device 5>

[0147] The telescopic device 5 has a pressure cylinder 51 connected to the upper surface of the front end of the structural frame 22 of the moving unit 2 through a pin structure, and a piston rod 52 that can freely extend and retract in the pressure cylinder 51. One end of the piston rod 52 is connected to the rear side of the main rod 11 of the loading and unloading unit 1 through a pin structure as described above.

[0148] The main function of the telescopic device 5 is that since the pressure cylinder 51 has a certain prefabricated pressure. When the main rod 11 together with the drum is manually rotated to the horizontal position (especially when the guide cylinder 42 of the lifting device 4 needs to move upward along the guide rod 41), it can bear most of the weight of the drum.

[0149] Therefore, the angles formed by any two components among the loading and unloading unit 1, the telescopic device 5, and the moving unit 2 are freely and flexibly variable within the required range, thus not affecting the function of the lifting device 4.

[0150] <Usage method>

[0151] The usage method of this embodiment is roughly the same as that of the above first embodiment. However, in order to show that this embodiment has the technical effect of being able to rotate the loading and unloading unit to the horizontal position and directly take materials and clean the drum, the following takes the process of disassembling the drum from the centrifuge and taking materials and cleaning as an example for description.

[0152] In use, only one operator is required. Hold the structural frame 22 of the moving unit 2 (or the handrail extending from the structural frame 22) by hand, and move the device of the present invention to the centrifuge. At the same time, rotate the eccentric wheel 31 to the position where the distance to the tip bearing 122 is minimized. Align the fork 121 of the claw 12 below the protruding part of the drum and push it forward, so that the arc part of the fork 121 of the claw 12 fits with the arc of the drum. Rotate the eccentric wheel 31 through the grip rod 32 to make the distance between the center of the eccentric wheel 31 and the tip bearing 122 of the claw 12 the largest. During the rotation of the eccentric wheel 31, the fork 121 of the claw 12 is lifted upward, and force is applied to the drum through the anti-slip lug 123 protruding upward in the fork 121, so as to vertically lift the drum upward. And through the action of the anti-slip lug 123 protruding upward at the front end of the fork 121, the clamped drum is also vertically lifted upward until the bottom of the drum is disengaged from the constraint of the sliding bearing assembly. Since the position of the anti-slip lug 123 exceeds the center line of the drum, it naturally hooks the protruding part of the drum, thus preventing the drum from falling forward. At the same time, due to the action of the fitting positioning lug 124, the liquid collecting tray sleeved on the upper part of the drum is also lifted.

[0153] Move the device of the present invention clamping the drum backward a certain distance to an empty place, and manually remove the liquid collecting tray taken out together with the drum above the drum. The liquid collecting tray can be placed on the bottom frame.

[0154] After that, the operator pulls the main rod 11 backward through the grip rod 32 (or directly pulls the main rod 11). At this time, since the main rod 11, the lifting device 4 and the telescopic device 5 are all connected by a pin structure, the main rod 11 can rotate freely backward. When rotated to a certain angle, the guide cylinder 41 of the lifting device 4 connected to the main rod 11 can move upward along the guide rod 42, and after the telescopic device 5 is telescoped to a certain distance, it continues to rotate relative to the main rod 11 and the structural frame 22 to form a substantially horizontal state. Finally, the device loading and unloading auxiliary device of the present invention is formed as Figure 12 the state shown.

[0155] When the loading and unloading unit 1 is in a horizontal state, pick up the mechanical tool placed on the bottom frame in advance, directly open the lower end cover of the drum below the drum, and take materials and clean the drum. There is no need to move the drum to other workbenches, that is, there is no need to manually carry the drum to the workbench and place it horizontally for disassembly, material taking and cleaning. Therefore, the device loading and unloading auxiliary device in this embodiment can greatly save manpower and improve work efficiency (placing the drum is the reverse operation of the above process).

[0156] <Related Variation Examples>

[0157] The equipment loading and unloading auxiliary device provided by the present invention is mainly designed for equipment such as the drum of different centrifuges with natural height positions, which need to vertically lift the loading and unloading object by a certain distance during loading and unloading, and rotate it to a horizontal position according to its characteristics.

[0158] However, in actual industrial applications, the claw 12 can be formed into a freely detachable structure. By this modification, different-shaped claws can be replaced for clamping different products.

[0159] For example, when the loading and unloading object does not need to be vertically lifted by a certain distance but needs to be rotated to a horizontal position during loading and unloading, the claw adjusting device 3 of the present invention can be not installed, but the lifting device 4 and telescopic device in the second embodiment can be configured.

[0160] For another example, if the appearance of the loading and unloading object is formed into a cube and there is no drop structure similar to the drum on the appearance, the claw 12 can be replaced with a structure such as a locking member that sets two holes on both sides of the fork of the claw 12 and adjusts the spacing of the clamping space through screws or the like.

[0161] Therefore, through the above examples, it can be understood that for the equipment loading and unloading auxiliary device involved in the present invention, based on the loading and unloading unit 1 and the moving unit 2 as the basic structure, according to the different characteristics of the clamping object, different claws can be freely selected and configured, and any one of the claw adjusting device 3, the lifting device 4, and the telescopic device 5 can be selected and applied, and different technical effects can be achieved.

[0162] <Summary of the Invention>

[0163] 1. By freely replacing different claw structures and combining with the moving unit of the present invention, different objects can be clamped, loaded, and transported.

[0164] 2. For the disassembly of special equipment, the operation of loading and unloading can be achieved by adjusting the angle formed by the claw and the main rod. The device for adjusting the angle between the claw and the main rod is not particularly limited as long as it can adjust the angle.

[0165] 3. Through the lifting device, not only can equipment at different height positions be loaded and unloaded, but also it has high industrial applicability.

[0166] 4. In order to further ensure the safety of the device, certain lifting guidance and rotation guidance can be carried out through the telescopic device.

[0167] 5. The operations of the eccentric lever structure, the lifting device 4, and the telescopic device 5 of the present invention can all be carried out by electric, pneumatic, or other means.

[0168] <Advantageous Effects>
