Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing technology, and in particular to a piston rod transfer platform. Background Technology

[0002] In the process of machining hydraulic cylinders, the piston rod is a relatively important installation component. In order to facilitate the transfer of the piston, a hand-push lifting platform is generally used. It can not only transport the piston rod over short distances, but also transport it vertically, which makes it easier to install the piston rod of some large hydraulic cylinders.

[0003] When using a hand-operated lifting platform to transport and lift piston rods, since the piston rod is cylindrical in shape, if the lifting platform vibrates under external force, the piston rod may shift on the platform, or even fall off the platform and be damaged. Utility Model Content

[0004] This utility model proposes a piston rod transfer platform to solve the problem that if the lifting platform vibrates under the action of external force during rotation, the piston rod may shift on the platform, or even fall off the platform and be damaged.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a piston rod transfer platform, including a movable frame, a push rod fixedly installed on one side of the top of the movable frame, scissor lifting arms slidably installed on both sides of the inner wall of the movable frame, a hydraulic rod rotatably installed on the top of the movable frame, one end of the hydraulic rod rotatably installed on the outer surface of the scissor lifting arm, a loading platform installed on the top of the scissor lifting arm, and a limiting device provided on the top of the loading platform. The limiting device limits the piston rod by setting two side plates and two baffles.

[0006] The effect achieved by the above-mentioned components is as follows: by setting two baffles and two side plates, the piston rod is placed between the two baffles and two side plates, so that the piston rod can only move between the two baffles and two side plates, thereby limiting the piston rod and helping to prevent the piston rod from falling off the platform during transportation and causing damage to the piston rod.

[0007] Preferably, the limiting device includes several base plates, which are slidably inserted into the top of the platform. Side plates are installed on both sides of the base plates. Baffles are symmetrically slidably installed on the inner walls of the two side plates. An auxiliary plate is installed on the side of the two baffles that are far apart. A threaded rod is fixedly installed on the side of the two auxiliary plates that are close together. The two threaded rods have the same thread size and opposite direction. The outer surfaces of the two threaded rods are threadedly connected to the same threaded cylinder.

[0008] The effect achieved by the above components is as follows: when the piston rod is placed between the two side plates, and then the threaded cylinder is rotated, the threaded cylinder will drive the two threaded rods to move synchronously in opposite directions on the inner wall of the threaded cylinder. The threaded rods will drive the baffle connected to the auxiliary plate to move until the two baffles abut against each other, and then the two baffles and the two side plates can limit the piston rod.

[0009] Preferably, an operating block is fixedly installed on the outer surface of the threaded cylinder, and the outer surface of the operating block is provided with protrusions.

[0010] The effect achieved by the above components is as follows: by setting up an operating block with protrusions, rotating the operating block can drive the threaded cylinder to rotate. At the same time, the protrusions on the outer surface of the threaded cylinder can increase the friction when rotating the operating block, so as to have an anti-slip effect when rotating the operating block.

[0011] Preferably, the same abutment is slidably installed on the side of the two side plates that are close to each other, and springs are symmetrically fixed on the side of the abutment and the bottom plate that are close to each other.

[0012] The effect achieved by the above components is as follows: by setting a stop plate, under the action of the spring, when the piston rod is placed on the stop plate, the piston rod will drive the stop plate to compress the spring, and the spring will also push the stop plate, so that the stop plate drives the piston rod to move, so that the outer surface of the piston rod abuts against the baffles. Then the stop plate and the two baffles can clamp and fix the piston rod, and can further limit the piston rod (the spring is equipped with a limit mechanism inside, which is essentially a round rod that can slide on the inner wall of the cylinder, mainly playing the role of limiting and guiding the spring, in order to prevent the spring from bending during deformation).

[0013] Preferably, a rubber sheet is adhered to the top of the abutment.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up a rubber plate, the top can be driven to abut against the outer surface of the piston rod instead of the abutment plate, which can increase the friction between the abutment plate and the piston rod, making the limiting of the piston rod more stable, and at the same time, it can play a certain protective role for the piston rod.

[0015] Preferably, the disassembly assembly includes two slot plates, which are symmetrically installed on both sides of the platform. One side plate has extension plates installed on both sides. The outer surface of the extension plates is inserted between the slot plates and the platform. A threaded pin is installed on one side of the extension plate. The threaded pin is slidably inserted into the inner wall of the slot plate. A nut is threaded onto the outer surface of the threaded pin.

[0016] The effect achieved by the above components is as follows: the base plate is inserted into the inner wall of the stage, and the extension plate is inserted between the slot plate and the stage. The base plate is pushed to reach the appropriate position. Then the nut is rotated so that the nut presses against the slot plate, and the slot plate presses against the extension plate, which can fix the base plate and the stage. At the same time, the base plate can be disassembled, which makes it easy to add or remove the limiting device according to actual needs, and also makes it easy to replace and maintain the limiting device separately.

[0017] Preferably, rubber strips are symmetrically bonded to the inner wall of one side of the slot plate, and the nut is disposed on one side of the rubber strip.

[0018] The effect achieved by the above components is that by setting the rubber strip, the friction between the nut and the slot plate can be increased, making the nut less likely to loosen.

[0019] Preferably, a mounting plate is provided on one side of the platform, and two locking blocks are symmetrically installed on one side of the mounting plate. The two locking blocks are symmetrically inserted into the inner wall of the slot plate, and the locking blocks are fixedly installed on one side of the platform by screws.

[0020] The effect achieved by the above components is as follows: by setting the mounting plate, after the base plate is installed, the locking blocks at both ends of the mounting plate are inserted into the inner walls of the two slot plates respectively, so that one side of the mounting plate abuts against one side of the platform. Then, the locking blocks are fixed by screws. The mounting plate can limit the base plate, which helps to prevent the base plate from falling off the platform due to accidental operation.

[0028] Example 1, referring to Figures 1-4 As shown, this embodiment discloses a piston rod transfer platform, including a movable frame 1. A push rod 4 is fixedly installed on one side of the top of the movable frame 1. Scissor lifting arms 5 are slidably installed on both sides of the inner wall of the movable frame 1. A hydraulic rod 6 is rotatably installed on the top of the movable frame 1. One end of the hydraulic rod 6 is rotatably installed on the outer surface of the scissor lifting arm 5. During the extension and retraction process, the hydraulic rod 6 will drive the top of the scissor lifting arm 5 to move up and down stably. A platform 7 is installed on the top of the scissor lifting arm. A limiting device 2 is provided on the top of the platform 7. The limiting device 2 limits the piston rod by setting two side plates 22 and two baffles 23. By setting two baffles 23 and two side plates 22, the piston rod is placed between the two baffles 23 and two side plates 22, so that the piston rod can only move between the two baffles 23 and two side plates 22, thereby limiting the piston rod and preventing the piston rod from falling off the platform 7 during the transportation of the piston rod and causing damage to the piston rod.

[0029] Reference Figures 2-4 As shown, the limiting device 2 includes several base plates 21, which are slidably inserted into the top of the platform 7. Side plates 22 are installed on both sides of each base plate 21. Baffles 23 are symmetrically slidably installed on the inner walls of the two side plates 22. An auxiliary plate 24 is installed on the side of each of the two baffles 23 that is far apart. A threaded rod 25 is fixedly installed on the side of each of the two auxiliary plates 24 that is close together. The two threaded rods 25 have the same thread size but opposite directions. The outer surfaces of the two threaded rods 25 are threadedly connected to the same threaded cylinder 26. When the piston rod is placed between the two side plates 22 and the threaded cylinder 26 is rotated, the threaded cylinder 26 will drive the two threaded rods 25... 5. The threaded cylinder 26 extends and retracts synchronously in opposite directions on its inner wall. The threaded rod 25 drives the baffle 23 connected to the auxiliary plate 24 to move until the two baffles 23 abut against each other. Then, the two baffles 23 and the two side plates 22 can limit the piston rod. An operating block 27 is fixedly installed on the outer surface of the threaded cylinder 26. The outer surface of the operating block 27 is provided with protrusions. By providing the operating block 27 with protrusions, rotating the operating block 27 can drive the threaded cylinder 26 to rotate. At the same time, the protrusions on the outer surface of the threaded cylinder 26 can increase the friction when rotating the operating block 27, so that the operating block 27 has an anti-slip effect when rotating.

[0030] Reference Figures 2-4 As shown, a common abutment 28 is slidably mounted on the side of the two side plates 22 that are close to each other. A spring 29 is symmetrically fixed on the side of the abutment 28 and the side of the bottom plate 21 that are close to each other. By setting the abutment 28, under the action of the spring 29, when the piston rod is placed on the abutment 28, the piston rod will drive the abutment 28 to compress the spring 29, and the spring 29 will also push the abutment 28, causing the abutment 28 to move the piston rod. This causes the outer surface of the piston rod to abut against the mutually abutting baffles 23. Thus, the abutment 28 and the two baffles 23 can clamp and fix the piston rod, enabling the piston rod to be moved. The piston rod is further limited by a limiting mechanism inside the spring 29. Essentially, it is a round rod that can slide on the inner wall of the cylinder. It mainly serves to limit and guide the spring 29 to prevent it from bending during deformation. A rubber plate 210 is bonded to the top of the abutment plate 28. By setting the rubber plate 210, it can replace the abutment plate 28 to drive the top to abut against the outer surface of the piston rod, which can increase the friction between the abutment plate 28 and the piston rod, making the limiting of the piston rod more stable, and at the same time, it can also provide a certain degree of protection for the piston rod.

[0031] Reference Figure 2 and Figure 3 As shown, the disassembly assembly 3 includes two slot plates 31, which are symmetrically installed on both sides of the platform 7. One of the side plates 22 has extension plates 37 installed on both sides. The outer surface of the extension plate 37 is inserted between the slot plate 31 and the platform 7. A threaded pin 32 is installed on one side of the extension plate 37. The threaded pin 32 is slidably inserted into the inner wall of the slot plate 31. A nut 33 is threadedly connected to the outer surface of the threaded pin 32. The base plate 21 is inserted into the inner wall of the platform 7, and the extension plate 37 is inserted between the slot plate 31 and the platform 7. The base plate 21 is pushed to the appropriate position. Then the nut 33 is rotated, so that the nut 33 presses against the slot plate 31, and the slot plate 31 presses against the extension plate 37. This fixes the base plate 21 and the platform 7, and also makes the base plate 21 detachable. This makes it easy to add or remove the limiting device 2 according to actual needs, and also makes it easy to replace and maintain the limiting device 2 separately.

[0032] Reference Figure 2 and Figure 3As shown, rubber strips 34 are symmetrically bonded to the inner wall of one side of the slot plate 31, and nuts 33 are set on one side of the rubber strips 34. By setting the rubber strips 34, the friction between the nuts 33 and the slot plate 31 can be increased, making it less likely for the nuts 33 to loosen. A mounting plate 35 is set on one side of the platform 7, and two locking blocks 36 are symmetrically installed on one side of the mounting plate 35. The two locking blocks 36 are symmetrically inserted into the inner wall of the slot plate 31. The locking blocks 36 are fixed to one side of the platform 7 by screws. By setting the mounting plate 35, after the installation of the base plate 21 is completed, the locking blocks 36 at both ends of the mounting plate 35 are inserted into the inner walls of the two slot plates 31 respectively, so that one side of the mounting plate 35 abuts against one side of the platform 7. Then the locking blocks 36 are fixed by screws. The mounting plate 35 can limit the base plate 21, which helps to prevent the base plate 21 from detaching from the platform 7 due to accidental operation.

[0033] Working principle: The piston rod is placed on the abutment plate 28 via two baffles 23. Pushing the abutment plate 28 downward causes it to compress the spring 29, which deforms. Rotating the operating block 27 then rotates the threaded cylinder 26. The threaded cylinder 26 causes two threaded rods 25 to extend and retract synchronously in opposite directions within the inner wall of the cylinder 26. The threaded rods 25 move the baffles 23 connected to the auxiliary plate 24 until the two baffles 23 abut against each other. Releasing the pressure on the abutment plate 28 causes the spring 29 to reset and move the abutment plate 28 towards the two baffles 23 until the outer surface of the piston rod abuts against one side of the two baffles 23. The two baffles 23 and the abutment plate 28 then clamp and fix the piston rod, while the two side plates 22 limit its movement. This effectively prevents the piston rod from falling off the platform 7 during transport and causing damage. The base plate 21 is inserted into the inner wall of the platform 7, and the extension plate 37 is inserted between the slot plate 31 and the platform 7. The base plate 21 is pushed to the appropriate position, and the nut 33 is rotated to press the rubber strip 34 on one side of the slot plate 31, thus fixing the base plate 21 and the platform 7. The locking blocks 36 at both ends of the mounting plate 35 are inserted into the inner walls of the two slot plates 31, and one side of the mounting plate 35 abuts against one side of the platform 7. The locking blocks 36 are then fixed with screws, thus limiting the position of the base plate 21 and preventing accidental detachment of the base plate 21 from the platform 7.
