Description

Technical Field

[0001] This utility model relates to the field of lifting devices, and in particular to a synchronous lifting device for pipes. Background Technology

[0002] In the current plastics industry, the device for lifting and tilting pipes into the finished product frame involves a cylinder-powered tilting plate that tilts the pipe, which then rolls up a ramp to the lifting point. A synchronous chain on the lifting machine hooks both ends of the pipe, lifting it to the top, where it rolls down into the finished product frame under its own weight. Normally, the hooks on the synchronous chain can hook both ends of the pipe. However, sometimes the pipe rolls down the ramp to the lifting point asynchronously, with one end in place while the other is not. In this case, the hook only hooks one end of the pipe for lifting, leaving the pipe tilted. When the hook turns back down after reaching the top, it may break the pipe, causing mechanical failure.

[0003] To address this, a pipe synchronous lifting device is proposed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a pipe synchronous lifting device to solve the issues raised in the background section.

[0005] The technical solution of this utility model is:

[0006] A pipe synchronous lifting device includes a lifting machine. The bottom end of the lifting machine is fixedly connected to symmetrically arranged support plates. A support plate is arranged between the two support plates. The top surface of the support plate is provided with a plurality of equidistant limiting strips. The bottom surface of the support plate is fixedly connected to symmetrically arranged support columns. The bottom side wall of the support column is fixedly connected to a rotating shaft. One end of the rotating shaft is fixedly connected to a connecting plate. The side wall of the connecting plate away from the rotating shaft is fixedly connected to a connecting shaft. The outer surface of the support plate is fixedly connected to a motor. The output end of the motor is fixedly connected to one of the connecting shafts.

[0007] The working principle of the above technical solution is as follows:

[0008] The connecting shaft can be rotated by a drive motor. The rotation of the connecting shaft causes the connecting plate to rotate around the connecting shaft as the center. This causes the rotating shaft support column to make an arc motion. After the pipe is placed between the two corresponding limit strips, the pallet can move towards the elevator along with the arc motion of the support column. This allows the pipe, which is limited by the limit strips, to be smoothly transported to the elevator, avoiding situations where it cannot be horizontally matched with the hooks on the surface of the elevator.

[0009] In a further technical solution, the top surface of the tray is fixedly connected to symmetrically arranged adjustment plates, the top surface of the adjustment plates is provided with equally spaced slots, and the bottom end of the limiting strip is fixedly connected to a plug, the plug being adapted to the diameter of the slot.

[0010] The above technical solution allows for easy adjustment of the spacing between each limiting strip, making it suitable for pipes with different supports.

[0011] In a further technical solution, a first limiting port is provided on the surface of the plug, a second limiting port is provided on the side wall of the adjusting plate, a limiting plug that penetrates to the inner wall of the first limiting port is inserted into the inner wall of the second limiting port, and a pull block is fixedly connected to one end of the limiting plug.

[0012] The above technical solution allows the limit bolt to be inserted into the inner wall of the first limit port, maintaining the stability of the limit strip during use.

[0013] In a further technical solution, a reset port is provided on the inner wall of the second limiting port, a baffle is fixedly connected to the outer surface of the limiting bolt, a spring is provided between the baffle and the pull block, and the end of the spring away from the baffle is fixedly connected to the inner wall of the reset port.

[0014] With the above technical solution, each time the position of the limiting strip is adjusted, the pull block is pulled outward to compress the spring. Then, when the first limiting port on the surface of the plug is opposite to the limiting plug, the spring's reset effect is used to allow the limiting plug to quickly limit the plug.

[0015] In a further technical solution, a connecting rod is fixedly connected between the bottom ends of the two connecting plates.

[0016] The above technical solution enables one connecting plate to rotate smoothly along with the other connecting plate when one of the connecting plates is driven to rotate by a motor, thereby achieving stability during the movement of both ends of the pallet.

[0017] In a further technical solution, the limiting strip is made of stainless steel.

[0018] The above technical solution avoids the adhesion of the pipe when limiting the pipe between the two limiting strips.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By setting a drive motor to rotate the connecting shaft, the connecting plate rotates around the connecting shaft as the center, thereby causing the rotating shaft support column to make an arc motion, which drives the pallet to move smoothly towards the hoist. This ensures that the pipe can be delivered to the hoist horizontally and synchronously at all times. This solves the problem of the pipe rolling down the slope to the hoisting point asynchronously, resulting in one end being in place while the other end is not, and thus the pipe being in a tilted state during the hoisting process.

[0031] Example:

[0032] Please see Figure 1-5 A pipe synchronous lifting device includes a lifting machine 1. The bottom end of the lifting machine 1 is fixedly connected to symmetrically arranged support plates 2. A support plate 3 is arranged between the two support plates 2. The top surface of the support plate 3 is provided with a plurality of equidistantly distributed limiting strips 4. The bottom surface of the support plate 3 is fixedly connected to symmetrically arranged support columns 5. The bottom side wall of the support column 5 is fixedly connected to a rotating shaft 6. One end of the rotating shaft 6 is fixedly connected to a connecting plate 7. The side wall of the connecting plate 7 away from the rotating shaft 6 is fixedly connected to a connecting shaft 8. The outer surface of the support plate 2 is fixedly connected to a motor 9. The output end of the motor 9 is fixedly connected to one of the connecting shafts 8.

[0033] The working principle of the above technical solution is as follows:

[0034] The connecting shaft 8 can be rotated by the drive motor 9. The rotation of the connecting shaft 8 can cause the connecting plate 7 to rotate around the connecting shaft 8 as the center. This allows the rotating shaft 6 and the support column 5 to make an arc motion. After the pipe is placed between the two opposite limit bars 4, the pallet 3 can move towards the elevator 1 along with the arc motion of the support column 5. This allows the pipe limited by the limit bars 4 to be smoothly transported to the elevator 1, avoiding the situation where it cannot be horizontally matched with the hooks on the surface of the elevator 1.

[0035] Please see Figure 2 and Figure 4 The top surface of the support plate 3 is fixedly connected with symmetrically arranged adjustment plates 11. The top surface of the adjustment plates 11 is provided with equally spaced slots 12. The bottom end of the limiting strip 4 is fixedly connected with a plug 13, and the diameter of the plug 13 is compatible with that of the slot 12.

[0036] The spacing between each limit bar 4 can be easily adjusted to accommodate pipes with different supports.

[0037] Please see Figure 4 and Figure 5 The surface of the plug 13 is provided with a first limiting port 14, and the side wall of the adjusting plate 11 is provided with a second limiting port 15. The inner wall of the second limiting port 15 is provided with a limiting plug 16 that penetrates to the inner wall of the first limiting port 14. One end of the limiting plug 16 is fixedly connected to a pull block 17.

[0038] The limit bolt 16 can be inserted into the inner wall of the first limit port 14 to maintain the stability of the limit strip 4.

[0039] Please see Figure 4 and Figure 5 The inner wall of the second limiting port 15 is provided with a reset port 18. A baffle 20 is fixedly connected to the outer surface of the limiting bolt 16. A spring 19 is provided between the baffle 20 and the pull block 17. The end of the spring 19 away from the baffle 20 is fixedly connected to the inner wall of the reset port 18.

[0040] Each time the position of the limiting bar 4 is adjusted, the pull block 17 can be pulled outward to compress the spring 19. Then, when the first limiting port 14 on the surface of the plug 13 is opposite to the limiting plug 16, the spring 19's reset effect allows the limiting plug 16 to quickly limit the plug 13.

[0041] Please see Figure 3 A connecting rod 10 is fixedly connected between the bottom ends of the two connecting plates 7.

[0042] When one of the connecting plates 7 is driven to rotate by the motor 9, it can smoothly carry the other connecting plate 7 to rotate, thereby achieving stability during the movement of both ends of the support plate 3.

[0043] Limiting strip 4 is made of stainless steel.

[0044] To prevent the pipe from sticking together when limiting the two limit strips 4.

[0045] During operation, firstly, adjust the spacing of the limit strips 4 according to the required pipe specifications and dimensions. During operation, pull the pull block 17 outwards to compress the spring 19, causing the limit pin 16 to be pulled out from the first limit port 14 on the surface of the plug 13. Then, pull the plug 13 at the bottom of the limit strip 4 out from the port 12 on the top surface of the adjusting plate 11, move it, and reinsert it. When the first limit port 14 aligns with the limit pin 16, release the pull block 17. Utilizing the restoring effect of the spring 19, allow the limit pin 16 to quickly insert into the first limit port 14, completing the adjustment of the spacing of the limit strips 4. Next, the pipe is placed between the two opposing limit bars 4, and the motor 9 is started. The output end of the motor 9 drives the connecting shaft 8 to rotate. The rotation of the connecting shaft 8 causes the connecting plate 7 to rotate around the connecting shaft 8. Then, the rotation of the connecting plate 7 drives the rotating shaft 6 to move. The rotating shaft 6 supports the column 5 in an arc motion. Finally, the arc motion of the support column 5 drives the pallet 3 to move towards the hoist 1, so that the pipe limited by the limit bars 4 is smoothly transported to the hoist 1, ensuring that the pipe can cooperate horizontally with the hooks on the surface of the hoist 1 to complete the synchronous lifting operation of the pipe.

[0046] The above-described embodiments merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
