Description

Technical Field

[0001] The invention relates to the technical field of port container lifting, in particular to a manual convenient lifting tool. Background Art

[0002] Containers are a group of tools that can be loaded and packaged for transportation and loaded and unloaded by mechanical equipment. Shear springs are made of elastic materials. Through their shear deformation ability, they can effectively absorb and disperse the vibration and impact energy from the equipment or system. During the transportation of containers, whether by sea or land, they will be affected by various vibrations and shocks, such as the beating of waves and uneven roads. The application of shear springs can significantly reduce the damage caused by these vibrations and shocks to the container and the goods inside, and improve the safety and stability of transportation. During the stacking of containers, shear springs can resist the interference of external forces or loads to ensure that the container operates stably within the predetermined working range, which helps prevent the container from tilting or collapsing during transportation and ensures the safety of the goods.

[0003] During routine safety inspections at ports, it is often found that the shear springs in the middle layer of containers are damaged. At this time, they need to be replaced in time to ensure the safety of the cargo stacking area. Since the shear springs are relatively thin, there are usually only a few centimeters between the upper and lower containers. At this time, traditional lifting tools such as jacks, fall chains, cranes, etc., are difficult to lift in such a narrow gap and often require the use of other large equipment.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention cooperates with the main shaft, the second limit rod and the slider to enable the blade to move back and forth quickly while following the main body. In this way, the rust block can be efficiently removed when the blade contacts the rust block, so that there is no rust block on the inner wall of the gap, ensuring the actual lubrication effect of the subsequent lubricant, so that the subsequent personnel can lift smoothly when operating by using the lever principle, and the maintenance personnel do not need to repeat lubrication, which is convenient to use;

[0026] At the same time, when the blade actually contacts the rust block, the rust block will be cut obliquely by the blade, so that the effect of rust removal can be guaranteed, that is, the subsequent lubrication effect is guaranteed, that is, the operation of maintenance personnel during lifting is guaranteed.

[0027] 2. The present invention cooperates with structures such as the paint shaft, rack row and rotating shaft to allow the two cleaning wheels to reciprocate while following the movement. In this way, the lubricant that has been squeezed on the inner wall of the gap can be fully applied, making the lubricant evenly distributed and not easy to fall off, thereby ensuring that subsequent maintenance personnel can perform lifting operations and further facilitating use.

[0028] 3. As the equipment moves forward, the rust blocks in both the upper and lower directions will be concentrated in front of the self-cleaning plate in the lower area. The present invention uses the cooperation of the self-cleaning gear, the gear block and the transmission rod to make the self-cleaning plate move back and forth, so that the rust blocks in this area can be pushed to the outside, so that they are out of the gap area and fall directly to the ground, thus avoiding the residual rust blocks from affecting the subsequent lubrication effect;

[0029] At the same time, the reciprocating movement of the self-cleaning plate has the characteristic of speed difference, so that under the action of inertia, the rust block can be moved to the outside of the gap as a whole, which can further ensure the effect of rust block removal, that is, provide good guarantee for subsequent lubrication, so that maintenance personnel can perform lifting operations smoothly without repeated lubrication operations.

[0030] Fourth, the present invention first performs environmental treatment on the area that needs lifting, including removing rust blocks caused by long-term use of the container, and then lubricates it to reduce friction during workpiece operation. Finally, the workpiece is used for lifting operations. In this way, the problem of lifting or demolition in narrow gaps can be solved, which greatly improves work efficiency and reduces operation difficulty and risk. After the shear spring is replaced, the residual lubricant can also play a rust-proof effect to a certain extent.

[0031] 5. The structure of the present invention is symmetrically arranged up and down, so that after taking it, the person can directly put it into the gap without making any other adjustments in direction, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] For example, see Figures 1 to 11 The present invention provides a manual convenient lifting tool, including a tool box 37 and a workpiece 1, and also includes a force rod 2 and a body 3. The surface of the workpiece 1 is provided with a force hole 4, and the surface of the workpiece 1 is provided with a narrow surface 101, a wide surface 102 and a transition arc 103.

[0047] See also Figure 4 A sheath 36 is fixedly connected to the surface of the main body 3. The sheath 36 is made of elastic material. Through the setting of the sheath 36, the maintenance personnel can put their palms into the sheath 36, and then the main body 3 can be easily moved.

[0048] The inner wall of the main body 3 is fixedly connected with a lubrication component 5, the top and bottom surfaces of the main body 3 are fixedly connected with lubrication channels 6, both lubrication channels 6 are fixedly connected with the lubrication component 5, and the upper and lower sides of the main body 3 are provided with blades 7, self-cleaning plates 8 and two cleaning wheels 9.

[0049] See also Figure 4 The sizes of the four cleaning wheels 9 are all adapted to the size of the body 3, and the brush heads on the four cleaning wheels 9 are all detachable. By limiting the size of the cleaning wheel 9, the size of the cleaning wheel 9 can be limited to not be too large. At the same time, the detachable connection method of the brush head on the cleaning wheel 9 is a bolt connection. The detachable design makes it very convenient to clean the tool after multiple uses.

[0050] Two groups of pretreatment components are symmetrically arranged in the main body 3, and the pretreatment components include a rust removal component, a coating component, and a self-cleaning component. The coating component is transmission-connected with the rust removal component, and the self-cleaning component is transmission-connected with the rust removal component.

[0051] In the present embodiment, when the maintenance personnel find that the shear spring is damaged, the maintenance personnel opens the tool box 37 they carry with them, takes out the main body 3 first, and first uses the main body 3 to place it in the narrow space where the shear spring is located. While moving the main body 3, the two groups of pre-treatment components are started to operate. Taking a single pre-treatment component as an example, the rust removal component will be driven to operate first, so that the blade 7 moves back and forth quickly. By the rapid back and forth movement of the blade 7 and the process of the maintenance personnel moving the main body 3, the lifting area can be cleaned, so that the rust blocks in the lifting area can be efficiently removed. In the process of moving the main body 3, the lubricant in the lubrication component 5 is squeezed out through the lubrication channel 6 to the surface of the gap that has been processed by the blade 7. In the above removal process, The coating component is driven to operate synchronously, so that the two cleaning wheels 9 rotate synchronously. With the movement of the main body 3, the lubricant can be efficiently applied, so that the lubricant is evenly applied and not easy to fall off. The process of the lubricant in the lubricating component 5 being squeezed out in the above process can be realized by the circuit controller. Since only the process of squeezing out the lubricant can be used, it can be regarded as the prior art here, which has appeared in the published patents and is also more common in real life. Therefore, the specific working principle will not be repeated. The rust blocks removed in the above process fall in front of the self-cleaning plate 8 below. The self-cleaning component is driven to operate synchronously during the operation of the coating component, so that the self-cleaning plate 8 is moved back and forth with a speed difference characteristic, so that the rust blocks in this area can be efficiently pushed out of the gap;

[0052] By using two sets of pre-treatment components symmetrically arranged up and down, the upper and lower surfaces of the gap can be well treated to ensure the actual effect of subsequent lifting of the workpiece 1. After processing one area, the area on the other side of the shear spring is processed until the areas on both sides of the shear spring are processed.

[0053] After the environmental treatment is completed, the two workpieces 1 and the two force rods 2 in the tool box 37 are taken out in turn, the narrow surface 101 on the workpiece 1 is placed in the gap, and then the force rod 2 is inserted into the force hole 4 at its tail. By using the lever principle to apply pressure to the force rod 2, the narrow surface 101 can be easily transitioned to the wide surface 102 through the transition arc 103 by manpower, so that this area can be lifted. The other workpiece 1 and the force rod 2 are operated in the same way. The lubricated area on the other side of the shear spring is operated, so that the shear spring in the gap can be freely taken out and put in. After the shear spring is replaced, the two workpieces 1 can be taken out in turn.

[0054] This lifting tool can also be used in fixed screening sites. The free thickness of the double-layer rubber relaxation screen shear spring used in fixed screening production is only 51mm. After installation on the equipment, its thickness is 49mm. The total weight of the screen is about 90 tons. When replacing the shear spring, dozens of tons of force are required to expand the installation gap to more than 52mm. Traditional lifting tools are not easy to use and it is difficult to find the fulcrum. When using this lifting tool, you only need to put the 48mm narrow surface 101 into the installation gap first, and then use manpower to rotate the tool 90 degrees through the transition arc 103 to the 52mm wide surface 102. In this way, the installation gap can be easily expanded to the specified value. Using two of these tools, you can easily complete the replacement of the shear spring.

[0055] In the lifting work of the container, through the above process, the environment of the area that needs to be lifted is first treated, including the removal of rust caused by long-term use of the container, followed by lubrication to reduce friction during the operation of the workpiece 1, and finally the lifting operation is performed through the workpiece 1. In this way, the problem of lifting or demolition in narrow gaps can be solved, which greatly improves work efficiency and reduces operation difficulty and risk.

[0056] See also Figures 4 to 11The rust removal component includes a shell 10 and a main shaft 11, the shaft arm of the main shaft 11 is fixedly connected to a main rod 12, the end of the main rod 12 is rotatably connected to a fixed shaft 13, the inner wall of the shell 10 is fixedly connected to a limit rod 14, the rod wall of the limit rod 14 is slidably connected to a transmission block 15, the surface of the transmission block 15 is fixedly connected to a rectangular frame 16, the fixed shaft 13 is slidably connected to the inner wall of the rectangular frame 16, the surface of the transmission block 15 is fixedly connected to a displacement plate 17, the surface of the displacement plate 17 is provided with a displacement groove 18, the groove wall of the displacement groove 18 is slidably connected to a displacement shaft 19, the inner wall of the shell 10 is fixedly connected to a limit rod 20, the inner wall of the limit rod 20 is slidably connected to a slider 21, the surface of the slider 21 is provided with a through hole for the displacement shaft 19 to pass through, the surface of the slider 21 is fixedly connected to an L-shaped rod 22, and the end of the L-shaped rod 22 is fixedly connected to the surface of the blade 7;

[0057] A stabilizing seat 23 is fixedly connected to the surface of the housing 10 , and a notch 1 for displacement of the stabilizing seat 23 is provided on the surface of the blade 7 .

[0058] In this embodiment, when the body 3 is moved, the housing 10 is synchronously driven to move. At this time, the main shaft 11 is rotated. The main rod 12 is rotated by the rotation of the main shaft 11. The fixed axis 13 is rotated by the rotation of the main rod 12. Figure 7 In the state shown, a clockwise circular displacement is performed in the top view direction. The rectangular frame 16 can be pushed to move back and forth through the circumferential displacement of the fixed axis 13. The transmission block 15 can be synchronously driven to slide back and forth along the limit rod 14 through the reciprocating displacement of the rectangular frame 16. In the process of the reciprocating displacement of the transmission block 15, the displacement plate 17 is synchronously driven to move back and forth, that is, the displacement groove 18 on the displacement plate 17 is driven to move back and forth. Through the displacement of the displacement groove 18, the displacement shaft 19 can be pushed to slide along the groove wall of the displacement groove 18. Since the displacement shaft 19 is also constrained by the slider 21, the displacement shaft 19 will push the slider 21 to slide back and forth quickly along the inner wall of the limit rod 20. Through the reciprocating sliding of the slider 21, the blade 7 can be quickly moved back and forth through the transmission of the L-shaped rod 22.

[0059] The blade 7 can efficiently remove the rust blocks when it contacts them by rapid reciprocating movement, so that there is no rust block on the inner wall of the gap, ensuring the actual lubrication effect of the subsequent lubricant, so that the subsequent personnel can lift smoothly when operating by lever principle, and the maintenance personnel do not need to repeat lubrication, which is convenient to use;

[0060] At the same time, since the main body 3 is pushed by the maintenance personnel, that is, the blade 7 moves forward alternately relative to the gap where the shear spring is located, so when the blade 7 actually contacts the rust block, the rust block will be cut obliquely by the blade 7, so that the effect of the rust removal work can be guaranteed, that is, the subsequent lubrication effect is guaranteed, that is, the operation of the maintenance personnel during lifting is guaranteed.

[0061] See also Figures 4 to 11 The coating component includes two coating shafts 24, and the two coating shafts 24 are rotatably connected to the inner wall of the shell 10. The shaft arms of the two coating shafts 24 are fixedly connected with coating gears 25. The inner wall of the shell 10 is fixedly connected with two limit rods 26, and the rod walls of the two limit rods 26 are slidably connected with rack rows 27. The two rack rows 27 are fixedly connected to the top surface of the rectangular frame 16, and the teeth of the two rack rows 27 are respectively meshed with the teeth of the two coating gears 25. Through openings are opened on both sides of the shell 10, and the inner wall of the shell 10 is rotatably connected with two rotating shafts 28. The positions of the two rotating shafts 28 located at the through openings are respectively connected to the shaft arms of the two coating shafts 24 through pulley assemblies 29.

[0062] See also Figure 7 The sizes of the two rack rows 27 are respectively adapted to the sizes of the two coating gears 25, and the sizes of the two openings are respectively adapted to the sizes of the two pulley assemblies 29. By limiting the sizes of the rack rows 27 and the coating gears 25, the structure will not have tooth jamming during transmission. At the same time, by limiting the size of the openings, the inner wall of the housing 10 will not block the transmission of the pulley assembly 29.

[0063] The two cleaning wheels 9 are fixedly connected to the ends of the two rotating shafts 28 respectively.

[0064] In this embodiment, during the reciprocating movement of the above-mentioned rectangular frame 16, the two rack rows 27 are synchronously driven to move, so that the two paint gears 25 can be rotated, and then the two paint shafts 24 are rotated, so that through the rotation of the two paint shafts 24, under the respective transmission of the two pulley assemblies 29, the two rotating shafts 28 can be reciprocated. Through the reciprocating rotation of the two rotating shafts 28, the two cleaning wheels 9 can be reciprocated. In this way, as the main body 3 moves forward, the reciprocating rotation of the two cleaning wheels 9 can fully apply the lubricant that has been squeezed on the inner wall of the gap, so that the lubricant is evenly distributed and not easy to fall off, thereby ensuring that subsequent maintenance personnel can perform lifting operations, which is further convenient for use.

[0065] Embodiment 2, based on the above embodiment:

[0066] See also Figures 5 to 11The self-cleaning component includes a self-cleaning gear 30, which is fixedly connected to the shaft wall of the main shaft 11. The inner wall of the shell 10 is fixedly connected to a limiting rod 31. The rod wall of the limiting rod 31 is slidably connected with a tooth block 32. The teeth of the tooth block 32 are meshed with the teeth of the self-cleaning gear 30. The rod wall of the limiting rod 31 is sleeved with two springs 33. The two ends of the two springs 33 are respectively fixedly connected to the surface of the tooth block 32 and the inner wall of the shell 10. The surface of the tooth block 32 is fixedly connected with a transmission rod 34. The surface of the shell 10 is provided with an opening for the transmission rod 34 to move. The end of the transmission rod 34 is fixedly connected to the surface of the self-cleaning plate 8.

[0067] See also Fig.11 , also includes a driving component, the driving component includes a motor 35, the motor 35 is fixedly connected to the inner wall of the shell 10, the output end of the motor 35 is fixedly connected to the end of the main shaft 11, and by starting the motor 35, the main shaft 11 can be easily driven to rotate.

[0068] In this embodiment, the main shaft 11 can be rotated by starting the driving component, and in the process of the above-mentioned main shaft 11 rotating, the self-cleaning gear 30 will be synchronously driven to rotate, so that the tooth block 32 can be pushed to move along the rod wall of the limit rod 31. At this time, the two springs 33 are deformed. As the self-cleaning gear 30 continues to rotate, when the teeth of the tooth block 32 disengage from it, at this time, under the elastic action of the two springs 33, the tooth block 32 will be quickly reset along the rod wall of the limit rod 31 and re-engage with the teeth of the self-cleaning gear 30. In this way, the tooth block 32 can be moved back and forth under the continuous rotation of the self-cleaning gear 30. At this time, the self-cleaning plate 8 can be moved back and forth through the transmission of the transmission rod 34. Figure 4 It can be seen that as the equipment moves forward, the rust blocks in the upper and lower directions will be concentrated in front of the self-cleaning plate 8 in the lower area, and the cross-sectional shape of the gap is an inclined concave shape. At this time, the rust blocks in this part of the area can be pushed to the outside through the reciprocating displacement of the self-cleaning plate 8, leaving the gap area and falling directly to the ground, so as to avoid the residual rust blocks affecting the subsequent lubrication effect;

[0069] At the same time, it can be seen from the structure that the reciprocating displacement of the tooth block 32 is driven by the self-cleaning gear 30 for one part, and is driven by the elastic recovery of the spring 33 for another part. It can be seen that the reciprocating displacement of the self-cleaning plate 8 has a speed difference, and the speed driven by the spring 33 is faster. From the rotation direction of the above-mentioned fixed shaft 13, it can be seen that the self-cleaning plate 8 will first move toward the outside of the gap at a relatively slow speed, and the rust blocks in contact with it will be displaced together. Then the self-cleaning plate 8 will quickly move toward the inside of the gap for reset. In this way, under the action of inertia, the rust blocks move toward the outside of the gap as a whole, which can further ensure the effect of rust block removal, that is, provide good guarantee for subsequent lubrication, that is, maintenance personnel do not need to repeat the lubrication operation.

[0070] Working principle: When the maintenance personnel find that the shear spring is damaged, the maintenance personnel open the tool box 37 they carry with them, take out the body 3 first, use the body 3 first, place it in the narrow space where the shear spring is located, and start the two motors 35 while moving the body 3. Taking a single motor as an example, through the operation of the motor 35, the blade 7 moves back and forth quickly while following the movement of the body 3, so that the area to be lifted can be cleaned and the rust in the area to be lifted can be efficiently removed. In the process of moving the body 3, the lubricant in the lubrication component 5 is squeezed out through the lubrication channel 6 to the gap surface that has been processed by the blade 7. The movement of the body 3 causes the two cleaning wheels 9 to rotate synchronously, so that the lubricant can be efficiently applied, so that the lubricant is evenly applied and not easy to fall off, and the removed rust blocks fall in front of the self-cleaning plate 8 below. At this time, the self-cleaning plate 8 performs a reciprocating displacement with a speed difference characteristic, which can efficiently push the rust blocks in this area out of the gap, completing the entire rust removal process. Through the two sets of pre-treatment components symmetrically arranged above and below, the upper and lower surfaces of the gap can be well treated to ensure the actual effect of subsequent workpiece 1 using lifting. After processing one area, the area on the other side of the shear spring is processed until the areas on both sides of the shear spring are processed;

[0071] After the environment is improved, the two workpieces 1 and the two force rods 2 in the tool box 37 can be taken out in turn, and the workpiece 1 can be put into the gap so that the narrow surface 101 on the workpiece 1 fits with the processed upper and lower inner walls of the gap, and then the force rod 2 is inserted into the force hole 4 at the tail thereof. By applying pressure to the force rod 2 using the lever principle, the narrow surface 101 can be easily transitioned to the wide surface 102 through the transition arc 103 by manpower, so that this area can be lifted. The other workpiece 1 and the force rod 2 can be operated in the same way, and the lubricated area on the other side of the shear spring can be operated, so that the shear spring in the gap can be freely taken out and put in. After the shear spring is replaced, the two workpieces 1 can be taken out in turn.

[0072] Through the above method, the environment of the area that needs lifting can be treated first, including removing rust blocks caused by long-term use of the container, followed by lubrication to reduce friction during operation of the workpiece 1, and finally lifting operation is performed through the workpiece 1. In this way, the problem of lifting or demolition in narrow gaps can be solved, which greatly improves work efficiency and reduces operation difficulty and risk. After the shear spring is replaced, the residual lubricant can also play a rust-proof effect to a certain extent.
