Technical Field

[0001] This utility model relates to the technical field of cement pipe handling equipment, specifically a safe loading and unloading device for cement pipes. Background Technology

[0002] Safety loading and unloading equipment for cement pipelines refers to disassembly equipment specifically designed for loading, transporting, and unloading cement pipelines. It ensures safe and efficient operation during these processes. Primarily used for limiting the movement of pipelines, it enables the assembly or unloading of cement pipelines through a corresponding power source.

[0003] A search revealed Chinese patent application CN202120413529.1, which discloses a safe loading and unloading device for cement pipelines. The device includes a main body with a right-angle lever welded to its bottom. A hydraulic cylinder is mounted on the top of the lever, and a connecting rod is mounted on the output end of the hydraulic cylinder. One end of the connecting rod has a through hole. A first rotating shaft is movably connected to the right-angle lever and the connecting rod through the through hole, and the first rotating shaft passes through both the right-angle lever and the connecting rod. A second rotating shaft is movably connected to the connecting rod near the first rotating shaft, and a load-bearing arm is mounted on its outer wall. A load-bearing rod is welded to the bottom of the load-bearing arm, and a first pressure sensor is mounted on the top surface of the load-bearing rod. A crane connector is connected to one end of the main body, and a fixed hanging rod is mounted on the top of the crane connector. This safe loading and unloading device for cement pipelines has a simple and reasonable structure, a novel design, effectively improves loading and unloading efficiency, and is easy and convenient to operate, possessing high practical value.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The existing technologies involve inserting load-bearing rods into cement pipes, fixing the pipes, and then using hoisting equipment for loading and unloading. However, in actual use, when the cement pipes are finally placed on the ground after being erected, the weight of the pipes, especially large-diameter and long ones, can cause significant impact when lowered from the loading / unloading equipment into the rigid ground. This impact may exceed the pipe's tolerance limit, leading to cracks, damage, or even breakage on the surface. Therefore, it is essential to design a practical and highly protective safe loading and unloading device for cement pipes. Utility Model Content

[0005] The purpose of this invention is to provide a safe loading and unloading device for cement pipelines to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a safe loading and unloading device for cement pipelines, including a loading and unloading frame, a support plate fixedly connected to one side of the loading and unloading frame, a drive groove opened on the lower side of the inner wall of the loading and unloading frame, a hydraulic cylinder fixedly connected to the upper side of the inner wall of the drive groove, a pressure block fixedly connected to the output end of the hydraulic cylinder, and a lower pressure plate fixedly connected to one side of the pressure block.

[0007] A buffer groove is provided on the lower side of the pressure block, and a buffer block is slidably fitted on the inner wall of the buffer groove. An adjustment component is provided between the buffer block and the buffer groove. A piston groove is provided on the lower side of the buffer block, and an exhaust hole is provided on one side of the inner wall of the piston groove. A piston block is slidably fitted on the inner wall of the piston groove, and two return springs are fixedly connected between the piston block and the piston groove.

[0008] According to the above technical solution, the adjustment component includes an adjustment groove formed on one side of the inner wall of the buffer groove, a force-bearing screw rotatably fitted on the inner wall of the adjustment groove, and a lifting block threaded onto the force-bearing screw and fixedly connected to the buffer block.

[0009] According to the above technical solution, a force-bearing plate is fixedly connected to the lower side of the piston block, and a soft pad is fixedly connected to the lower side of the force-bearing plate.

[0010] According to the above technical solution, two guide openings are provided on the lower side of the buffer block, and a guide rod that slides in cooperation with the two guide openings is fixedly connected to the upper side of the force plate.

[0011] According to the above technical solution, a limiting plate is fixedly connected to the upper side of the support plate, and a reinforcing rib is fixedly connected between the limiting plate and the loading and unloading frame.

[0012] According to the above technical solution, the lower end of the force-bearing screw is fixedly connected to an operating ring, and a tightening bolt is threaded onto one side of the operating ring. The upper end of the tightening bolt abuts against the lower side of the pressure block.

[0013] According to the above technical solution, a scale groove is provided on one side of the buffer block.

[0014] According to the above technical solution, an anti-detachment opening is provided on one side of the loading and unloading frame, and an anti-detachment block that is fixedly connected to the pressure block is slidably fitted inside the anti-detachment opening.

[0015] This invention, by incorporating components such as a buffer block, piston groove, and piston block, allows the piston block to contact the ground during placement. The piston block then slides within the piston groove, compressing the air inside. This compressed air is then discharged through an exhaust port. The exhaust port's restriction dampens the piston block, preventing the fixed cement pipe from immediately impacting the ground, reducing the impact force, and allowing it to fall slowly when placed. This avoids surface and internal structural damage from rigid collisions, protecting the pipe's integrity and performance, and improving its protection during loading and unloading. Furthermore, the invention includes an adjustment component and a buffer block. By controlling the rotation of a force-bearing screw within the adjustment groove, the lifting block can be moved up and down, thus moving the buffer block accordingly. This allows adjustment of the length of the buffer block protruding from the buffer groove to accommodate cement pipes of different thicknesses, expanding the applicability of the device.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 The present invention provides a technical solution: a safe loading and unloading device for cement pipes, including a loading and unloading frame 1, a support plate 2 fixedly connected to one side of the loading and unloading frame 1, a drive groove 3 opened on the lower side of the inner wall of the loading and unloading frame 1, a hydraulic cylinder 4 fixedly connected to the upper side of the inner wall of the drive groove 3, a pressure block 5 fixedly connected to the output end of the hydraulic cylinder 4, and a lower pressure plate 6 fixedly connected to one side of the pressure block 5.

[0026] A buffer groove 7 is provided on the lower side of the pressure block 5. A buffer block 8 is slidably fitted on the inner wall of the buffer groove 7. An adjustment component 9 is provided between the buffer block 8 and the buffer groove 7. A piston groove 10 is provided on the lower side of the buffer block 8. An exhaust hole 11 is provided on one side of the inner wall of the piston groove 10. A piston block 12 is slidably fitted on the inner wall of the piston groove 10. Two return springs 13 are fixedly connected between the piston block 12 and the piston groove 10.

[0027] Please see Figure 3 and Figure 4 as well as Figure 5The adjusting component 9 includes an adjusting groove 901 formed on one side of the inner wall of the buffer groove 7, a force-bearing screw 902 rotatably fitted on the inner wall of the adjusting groove 901, the force-bearing screw 902 being made of alloy steel with high strength, hardness, and good toughness, good hardenability, and the ability to withstand heavy loads without easily fracturing, and having a high load-bearing capacity after thickening treatment, and a lifting block 903 threadedly fitted on the force-bearing screw 902 and fixedly connected to the buffer block 8. By controlling the rotation of the force-bearing screw 902 inside the adjusting groove 901, the lifting block 903 can be pushed to move up and down, thereby driving the buffer block 8 to move accordingly. This allows adjustment of the length of the buffer block 8 protruding from the buffer groove 7 to suit cement pipes of different thicknesses, thus improving the applicability of this equipment.

[0028] Please see Figure 5 A force-bearing plate 14 is fixedly connected to the lower side of the piston block 12, and a soft pad 15 is fixedly connected to the lower side of the force-bearing plate 14. When the piston block 12 contacts the ground, the soft pad 15 on the lower side of the force-bearing plate 14 contacts the ground first. The soft pad 15 can reduce the impact force between the piston block 12 and the ground, thereby reducing the impact force and noise generated when unloading to the ground or loading to the truck.

[0029] Please see Figure 5 Two guide ports 16 are provided on the lower side of the buffer block 8. A guide rod 17 that slides in cooperation with the two guide ports 16 is fixedly connected to the upper side of the force plate 14. When the force plate 14 and the piston block 12 move upward, the guide rod 17 slides in the corresponding guide port 16, which can guide the force plate 14.

[0030] Please see Figure 2 A limiting plate 18 is fixedly connected to the upper side of the support plate 2. A reinforcing rib 19 is fixedly connected between the limiting plate 18 and the loading and unloading frame 1. The limiting plate 18 can limit the length of the support plate 2 inserted into the pipe. The stability of the support plate 2 can be enhanced by connecting the reinforcing rib 19 with the lower side of the limiting plate 18 and the support plate 2.

[0031] Please see Figure 5 An operating ring 20 is fixedly connected to the lower end of the force-bearing screw 902. A tightening bolt 21 is threaded on one side of the operating ring 20. The upper end of the tightening bolt 21 abuts against the lower side of the pressure block 5. The operating ring 20 facilitates the operation of the force-bearing screw 902. After the operation is completed, the tightening bolt 21 is rotated to abut against the pressure block 5, thereby fixing the operating ring 20 and the force-bearing screw 902.

[0032] Please see Figure 5A scale groove 22 is provided on one side of the buffer block 8. When the buffer block 8 moves inside the buffer groove 7, the length of leakage can be judged by observing the length of the scale groove 22 aligned with the buffer groove 7, which facilitates the accuracy of subsequent adjustments.

[0033] Please see Figure 6 The loading and unloading frame 1 has an anti-detachment opening 23 on one side. Inside the anti-detachment opening 23, there is an anti-detachment block 24 that is fixedly connected to the pressure block 5. When the hydraulic cylinder 4 pushes the pressure block 5 to move, the anti-detachment block 24 will slide in the anti-detachment opening 23, which can guide the pressure block 5 and prevent the pressure block 5 from detaching from the loading and unloading frame 1.

[0034] The implementation principle of this application is as follows: When in use, the loading and unloading frame 1 is connected to the corresponding driving equipment, and then the external equipment drives the support plate 2 and the lower pressure plate 6 to move, so that the two are inserted into the interior of the corresponding cement pipe. Then, the hydraulic cylinder 4 pushes the pressure block 5 and the lower pressure plate 6 to move downward, so that the support plate 2 contacts the upper side of the inner wall of the cement pipe and the lower pressure plate 6 is fixed to the lower side of the inner wall of the cement pipe. Then, the displacement can be achieved by driving the loading and unloading frame 1 to be raised.

[0035] When moved to a suitable loading or unloading location, the piston block 12 will contact the ground. Then, the piston block 12 slides inside the piston groove 10, compressing the air inside the piston groove 10. The compressed gas will be discharged from the exhaust port 11. Due to the restriction of the exhaust port 11, the piston block 12 can be damped, so that the fixed cement pipe will not immediately hit the ground. After being gradually squeezed out from the exhaust port 11, the impact force on the cement pipe is reduced, avoiding damage to the surface and internal structure of the cement pipe due to rigid collision, thus protecting the integrity and performance of the pipeline. When the piston block 12 is completely squeezed into the interior of the buffer block 8, the cement pipe contacts the ground. The hydraulic cylinder 4 can be activated to reset and pull out the pipe. The piston block 12 is slowly squeezed by the reset spring 13 to reset the pipe, which is convenient for subsequent use.

[0036] By controlling the rotation of the force-bearing screw 902 inside the adjusting groove 901, the lifting block 903 can be pushed to move up and down, thereby driving the buffer block 8 to move accordingly. This allows the length of the buffer block 8 protruding from the buffer groove 7 to be adjusted to suit cement pipes of different thicknesses, thus improving the applicability of this equipment.
