Description

Technical Field

[0001] The invention relates to a transport mechanism, in particular to a hydraulic oil cylinder transport mechanism. Background Art

[0002] Hydraulic cylinder generally refers to hydraulic cylinder, which is a hydraulic actuator that converts hydraulic energy into mechanical energy. The hydraulic cylinder includes cylinder barrel, cylinder head, piston, piston rod, sealing device, buffer device and exhaust device. Once one of the components is damaged, the entire cylinder cannot be used. Not only attention should be paid to it during the production stage of the cylinder, but also more detailed protection is required during the long-distance transportation stage of the cylinder.

[0003] In the prior art, when transporting the oil cylinder, the outer side of the oil cylinder is often wrapped with anti-friction cardboard, the oil cylinder is placed on the transfer rack and locked and fixed, and then the entire transfer rack is loaded on a vehicle for long-distance transportation. However, in fact, the cardboard can only prevent friction. In the event of a real collision, the protective effect of the cardboard is extremely poor, and it is very easy to cause damage to the sealing structure of the end head and the end cover. In addition, due to the different weights of different hydraulic cylinders, for example, the weight of a long oil cylinder is very heavy, and it is also very difficult to wrap it with cardboard. The number of short hydraulic cylinders on the transfer rack is very large, and it is very laborious to pack them one by one. Therefore, the above-mentioned protection method is not suitable for them.

[0004] Therefore, this case aims to provide a hydraulic cylinder transfer mechanism, which can not only establish a separate protective barrier between the cylinders, but also be adjusted according to the sizes of different cylinder diameters. At the same time, it can also form protection on the inner side of the cylinder according to the length of the cylinder, so that it will not be affected by mutual forces and external influences during the transfer process.

[0009] A pressure-dividing downward-skimming structure, wherein an X-shaped steel is connected between the two pressing frames, and the pressure-dividing downward-skimming structure comprises a pneumatic chamber arranged at the lower end of the X-shaped steel, the pneumatic chamber is connected to an external air source, and the lower ends of the pneumatic chambers are respectively connected to the first folding bag and the second folding bag, and the first folding bag and the second folding bag are both provided with blocking strips, and the external air source inflates or exhausts the first folding bag and the second folding bag through the pneumatic chamber, and when the oil cylinder is a long oil cylinder, the first folding bag and the second folding bag are horizontally unfolded and tightly attached to the top surface of the topmost long oil cylinder, and when the oil cylinder is a short oil cylinder, the first folding bag and the second folding bag are longitudinally unfolded and tightly attached to the axial direction of the short oil cylinder.

[0010] As a further improvement, a straight groove is opened on the outer side of the transverse mounting frame, the interior of the transverse mounting frame is hollow and a middle positioning rail is set at the bottom, the docking seat slides on the middle positioning rail and the outer side cooperates with the locking piece passing through the straight groove.

[0011] As a further improvement, a threaded inner groove is provided on the outer side of the docking seat, and the locking component includes a threaded rod that cooperates with the threaded inner groove. A threaded pressure block is screwed on the threaded rod. When the threaded rod passes through the straight groove and cooperates with the threaded inner groove, the threaded pressure block is rotated and pressed onto the transverse mounting frame.

[0012] As a further improvement, adjacent docking seats are connected to form a linear structure through springs.

[0013] As a further improvement, the lowering cylinder includes a first lowering member and a second lowering member which are arranged in the inner chamber of the transverse mounting frame, and the first lowering member and the second lowering member are arranged at an interval and connected by a cross bar.

[0014] As a further improvement, the first lowering member and the second lowering member are of equal size in structure, the first lowering member comprises an intermediate shaft inserted in the cross bar, a dividing strip is wrapped around the outside of the intermediate shaft, a lap ring is fixed to the bottom of the dividing strip, and the lap ring is adapted to the mating member.

[0015] As a further improvement, the mating piece comprises a mounting block locked on the side of the bottom support frame, and a hook angle is provided on the mounting block, and the hook angle cooperates with the loop after the dividing strip is pulled down.

[0016] As a further improvement, the first folding bag and the second folding bag have the same structural size, the first folding bag includes a hard section communicating with the pneumatic chamber, a soft section is connected to the lower end of the hard section, and the blocking strip is fixed to the surface of the soft section.

[0017] As a further improvement, the blocking strip includes a transverse shock absorbing portion, and a buffer inner groove is provided on the inner side of the shock absorbing portion.

[0018] As a further improvement, a hanging ring is provided on the top of the pressing frame.

[0019] The beneficial effects of the present invention are:

[0020] In the transportation process of traditional hydraulic cylinders, either the cylinders are not directly coated so that the cylinders are in direct contact with each other, or multiple layers of isolation paper are directly coated on the cylinders. The former cylinders are prone to bumping, and the latter are more difficult to coat due to their heavy weight. Therefore, the present invention uses a newly added transverse separation structure. First, the docking seat can be moved according to the distribution position of the cylinders, so that it can adapt to cylinders of different specifications and sizes. After the docking seat is moved into place, the docking seat is fixed by a locking piece, and then the lowering tube is pulled down by a tool to extend the lowering tube and fix it to the matching piece, thereby forming a series of dividing strips that separate the two rows of cylinders. Even if the cylinders are subject to bumps during long-distance transportation, there is no need to worry about damage caused by excessive collisions between the cylinders.

[0021] Due to the different needs of different customers, the number of cylinders is uncertain during the installation process of the cylinder, so the docking seat needs to be adjusted in position. In order to make the position adjustment of the docking seat smoother, a middle positioning rail is provided at the bottom position of the horizontal mounting frame, which can carry the docking seat and allow the docking seat to slide thereon, and in order to facilitate the fixation of the docking seat, a straight groove is reserved on the outer side of the horizontal mounting frame for the installation and fixation of the docking seat.

[0022] After the docking seat is moved to a suitable position, the position of the docking seat needs to be fixed to prevent it from sliding during transportation. Therefore, the present invention first opens a threaded inner groove on the docking seat, and then matches the threaded rod and the threaded pressing block so that the threaded pressing block tightly presses the docking seat onto the horizontal mounting frame, so that it can be fixed after the position is adjusted.

[0023] Since a partition rod is needed to separate the oil cylinder, if a whole complete lowering structure is provided, it will directly block the partition rod. Therefore, the present invention arranges a first lowering member and a second lowering member, and arranges the first lowering member and the second lowering member at an interval, thereby avoiding the position of the partition rod and separating the oil cylinder at the front and rear positions, which can avoid jamming and achieve a separation effect.

[0024] After the first lowering member and the second lowering member are lowered, the loop is hooked downward by a tool so that the loop extends downward with the dividing strip until it can be moved to the position of the hook angle for fixation, thereby forming a complete dividing surface that is not easily separated due to bumps.

[0025] Although a transverse partition structure is provided between the cylinders, if the transfer structure transports short cylinders, there will be a certain gap between the cylinders in the same row. Although they have been pressed and fixed, they are still prone to left and right shaking. Therefore, the present invention provides a pressure-dividing and downward-sliding structure on the basis of the transverse partition structure. After the cylinders are positioned and fixed by the transverse partition structure, the pneumatic chamber is inflated by the vehicle-mounted inflation structure. After inflation, the lower halves of the first folding bag and the second folding bag will be tightly attached to the inner side surface of the short cylinder, thereby limiting and fixing the short cylinder on one side. Even for long cylinders, the first folding bag and the second folding bag can be lifted up so that the first folding bag and the second folding bag are covered at the top position of the long cylinder, which helps to limit the long cylinder to a certain extent.

[0026] During the setting process of the first folding bag and the second folding bag, since they have two states, it is not suitable to set them directly to hard or soft. Therefore, the present invention sets the part connected to the pneumatic chamber to a hard state, that is, the hard segment connected to the pneumatic chamber is in a fixed state, and the soft segment connected to the hard segment is set to a soft state, that is, it is a soft structure in the uninflated state, and its position can be replaced.

[0027] In order to improve the coordination effect between the folding bladder and the short hydraulic cylinder, the present invention sets the blocking strip on the soft section as a shock-absorbing part of an outward convex structure, and sets a buffer inner groove on the inner side of the shock-absorbing part, so that after the folding bladder, it can better coordinate with the convex position on the inner side of the short oil cylinder, thereby better fixing the oil cylinder.

[0043] Reference Figures 1 to 10As shown, a hydraulic cylinder transfer mechanism comprises four bottom fixed piles 10, wherein the interior of the bottom fixed piles 10 is hollow and a side support beam 20 is movably inserted therein, a bottom support frame 30 is arranged at the bottom of the outer side of the bottom fixed piles 10, a plurality of partition rods 40 are movably connected between the side support beams 20, a space for placing the cylinder is formed between the partition rods 40 and the partition rods 40, a pressing frame 50 is sleeved on the top of the side support beam 20, and the pressing frame 50 abuts against the topmost cylinder, and the transfer mechanism It also includes: a transverse partition structure, a groove is provided at the bottom of the pressing frame 50, the transverse partition structure includes a transverse mounting frame 101 arranged in the groove, a plurality of docking seats 102 are slidably installed on the inner side of the transverse mounting frame 101, the docking seats 102 are locked and fixed by corresponding locking members 103 according to the installation position of the oil cylinder, a lowering cylinder 104 is provided on the inner side of the docking seat 102, and matching members 105 are provided on the inner and outer sides of the bottom support frame 30. When all the oil cylinders are installed, the lowering cylinder 104 is pulled down. The lowering cylinder 104 separates the dividing strip 10412 in the lowering cylinder 104 between the two oil cylinders, and the bottom of the dividing strip 10412 extends and is connected to the matching piece 105; a pressure-dividing and downward-skimming structure, an X-shaped steel 51 is connected between the two pressing frames 50, and the pressure-dividing and downward-skimming structure includes a pneumatic chamber 201 arranged at the lower end of the X-shaped steel 51, the pneumatic chamber 201 is connected to an external air source, and the lower end of the pneumatic chamber 201 is respectively connected to the first folding bag 202 and the second folding bag 203, the The first folding bag 202 and the second folding bag 203 are both provided with blocking strips 204, and the external air source inflates or deflates the first folding bag 202 and the second folding bag 203 through the pneumatic chamber 201. When the oil cylinder is a long oil cylinder, the first folding bag 202 and the second folding bag 203 are horizontally unfolded and tightly attached to the top surface of the topmost long oil cylinder. When the oil cylinder is a short oil cylinder, the first folding bag 202 and the second folding bag 203 are longitudinally unfolded and tightly attached to the axial direction of the short oil cylinder.

[0044] In this embodiment, the position of the side support beam 20 on the bottom fixed pile 10 can be adjusted, and the position between the clamping frame 50 and the side support beam 20 can be adjusted by the adjustment rod on the clamping frame 50. Since this part is the existing technology, it will not be described in detail.

[0045] In this embodiment, the hydraulic cylinders are arranged in four layers. In other embodiments, they can be arranged in other layers, but they should not be arranged too high, otherwise the overall weight will be too heavy and it will be easy to deform at the lifting point during lifting.

[0046] When moving the transfer mechanism of this embodiment and the hydraulic cylinder therein, a lifting ring 52 is provided on the top of the clamping frame 50, and the entire mechanism can be directly lifted into the carriage of the transfer vehicle by the crane and the lifting ring 52 for stacking and transportation.

[0047] In the transportation process of traditional hydraulic cylinders, either the cylinders are not directly coated so that the cylinders are in direct contact with each other, or multiple layers of isolation paper are directly coated on the cylinders. The former cylinders are prone to bumping, and the latter are more difficult to coat due to their heavy weight. Therefore, this embodiment uses a newly added transverse separation structure. First, the docking seat 102 can be moved according to the distribution position of the cylinders, so that it can adapt to cylinders of different specifications and sizes. After the docking seat 102 is moved into place, the docking seat 102 is fixed by the locking member 103, and then the lowering tube 104 is pulled down by a tool so that the lowering tube 104 is extended and fixed to the matching member 105, thereby forming a series of separation belts separating the two rows of cylinders. Even if the cylinders are subject to bumps during long-distance transportation, there is no need to worry about damage caused by excessive collisions between the cylinders.

[0048] Due to the different needs of different customers, the number of cylinders is uncertain during the installation process of the cylinder, so the docking seat 102 needs to be adjusted in position. In order to make the position adjustment of the docking seat 102 smoother, a straight groove 1011 is opened on the outer side of the horizontal mounting frame 101. The interior of the horizontal mounting frame 101 is hollow and a middle positioning rail is set at the bottom. The docking seat 102 is slidably fitted on the middle positioning rail and the outer side cooperates with the locking piece 103 that passes through the straight groove 1011. By setting a middle positioning rail at the bottom position of the horizontal mounting frame 101, the docking seat 102 can be carried and allowed to slide thereon. In order to facilitate the fixation of the docking seat 102, a straight groove 1011 is reserved on the outer side of the horizontal mounting frame 101 for installing and fixing the docking seat 102.

[0049] After the docking seat 102 is moved to a suitable position, the position of the docking seat 102 needs to be fixed to prevent it from sliding during transportation. Therefore, a threaded inner groove is provided on the outer side of the docking seat 102 of this embodiment, and the locking member 103 includes a threaded rod 1031 that cooperates with the threaded inner groove. A threaded pressing block 1032 is screwed on the threaded rod 1031. When the threaded rod 1031 passes through the straight groove 1011 and cooperates with the threaded inner groove, the threaded pressing block 1032 is rotated and pressed on the horizontal mounting frame 101. First, a threaded inner groove is provided on the docking seat 102, and then the threaded rod 1031 and the threaded pressing block 1032 are matched so that the threaded pressing block 1032 tightly presses the docking seat 102 on the horizontal mounting frame 101, so that it can be fixed after the position is adjusted.

[0050] Since the size difference of the hydraulic cylinders is not too large, in order to prevent the positions of the docking seats 102 from deviating too much, the adjacent docking seats 102 form a straight line structure through the springs 106, so that the distance between the adjacent docking seats 102 can be controlled.

[0051] Since the oil cylinder needs to be separated by the partition rod 40, if a complete lowering structure is set up, it will directly block the partition rod 40. Therefore, the lowering cylinder 104 of this embodiment includes a first lowering member 1041 and a second lowering member 1042 arranged in the internal chamber of the horizontal mounting frame 101. The first lowering member 1041 and the second lowering member 1042 are arranged at intervals and connected by a cross bar 1043. By setting the first lowering member 1041 and the second lowering member 1042 and setting the first lowering member 1041 and the second lowering member 1042 at intervals, the position of the partition rod 40 can be avoided, and the oil cylinder can be separated at the front and rear positions at the same time, which can avoid jamming and achieve a separation effect.

[0052] Specifically, the first lowering member 1041 and the second lowering member 1042 are of equal size. The first lowering member 1041 includes an intermediate shaft 10411 inserted into the cross bar 1043. A separation belt 10412 is wound around the outside of the intermediate shaft 10411. A loop 10413 is fixedly connected to the bottom of the separation belt 10412. The loop 10413 is adapted to the matching member 105. The matching member 105 includes a mounting block 1051 locked on the side of the bottom support frame 30. A hook angle 1052 is provided on the mounting block 1051. The hook angle 1052 cooperates with the loop 10413 after the dividing strip 10412 is pulled down. After the first lowering member 1041 and the second lowering member 1042 are lowered, the loop 10413 is hooked downward by a tool, so that the loop 10413 extends downward with the dividing strip 10412 until it can be moved to the position of the hook angle 1052 for fixation, thereby forming a complete dividing surface that is not easily separated due to bumps. A torsion spring can be installed on the intermediate shaft 10411 according to actual conditions, so that the loop 10413 can be automatically reset after it is not restricted.

[0053] It should be emphasized that the thickness of the dividing strip 10412 can be selected according to the specific usage environment. For example, since the gap between the inner cylinders is larger, the thickness of the dividing strip 10412 needs to be larger, while the gap between the outer cylinders is smaller, so the thickness of the dividing strip 10412 does not need to be too large.

[0054] Although a transverse partition structure is provided between the cylinders, if the transfer structure transports short cylinders, there will be a certain gap between the cylinders in the same row. Although they have been pressed and fixed, they are still prone to left and right shaking. Therefore, the present invention provides a pressure-dividing and downward-sliding structure on the basis of the transverse partition structure. After the cylinders are positioned and fixed by the transverse partition structure, the pneumatic chamber 201 is inflated by the vehicle-mounted inflation structure. After inflation, the lower halves of the first folding bag 202 and the second folding bag 203 will be tightly attached to the inner side surface of the short cylinder, thereby unilaterally limiting and fixing the short cylinder. Even for long cylinders, the first folding bag 202 and the second folding bag 203 can be lifted up so that the first folding bag 202 and the second folding bag 203 are covered at the top position of the long cylinder, which helps to limit the long cylinder to a certain extent.

[0055] During the setting process of the first folding bag 202 and the second folding bag 203, since they have two states, it is not suitable to set them directly as hard or soft. Therefore, the first folding bag 202 and the second folding bag 203 of this embodiment have the same structure and size. The first folding bag 202 includes a hard section 2021 communicated with the pneumatic chamber 201, and a soft section 2022 is connected to the lower end of the hard section 2021. The blocking strip 204 is fixed to the surface of the soft section 2022. The part connected to the pneumatic chamber 201 is set to a hard state, that is, the hard section 2021 connected to the pneumatic chamber 201 is in a fixed state, and the soft section 2022 connected to the hard section 2021 is set to a soft state, that is, it is a soft structure in the uninflated state, and its position can be replaced.

[0056] In order to improve the coordination effect between the folding bladder and the short hydraulic cylinder, the blocking strip 204 of the present embodiment includes a transverse shock-absorbing portion 2041, and a buffer inner groove 2042 is provided on the inner side of the shock-absorbing portion 2041. The blocking strip 204 on the soft section 2022 is configured as a shock-absorbing portion 2041 with an outward convex structure, and a buffer inner groove 2042 is provided on the inner side of the shock-absorbing portion 2041, so that after the folding bladder, it can better coordinate with the raised position on the inner side of the short oil cylinder, thereby improving the fixing effect on the oil cylinder.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
