Description

Technical Field

[0001] This utility model relates to the field of pipe clamping technology, and in particular to a pipe clamping and hoisting mechanism. Background Technology

[0002] Pipe lifting refers to various tubular components that need to be lifted for production transfer, on-site installation, or maintenance and replacement. It is the lifting object in the fields of pipeline engineering, equipment installation, and municipal construction. The equipment clamped by the pipe body is the object used for fixing, positioning, and clamping operations in the fields of industrial production, engineering construction, and logistics transfer.

[0003] The pipe clamping and hoisting equipment only adopts a single-stage rigid jaw design. The curvature and size of the jaw are fixed, and it can only be used to fit specific specifications of pipe fittings. If it is necessary to switch to different specifications of pipe fittings, the machine must be stopped, the original jaws must be disassembled, and the corresponding specifications of jaw accessories must be replaced. The operation process is cumbersome. Although some equipment attempts to adapt to different pipe fittings by adjusting the jaw spacing, the number of jaws is small and the distribution is uneven. After adjustment, it can only contact a local area of ​​the pipe fitting. It cannot achieve a full fit for elliptical pipe fittings or pipe fittings with slight deformation, which can easily lead to problems such as loose clamping or local compression deformation.

[0022] 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.

[0023] Please see the appendix Figure 1 and attached Figure 2 An embodiment of the present invention includes an installation mechanism 1, a clamping mechanism 2 mounted on the surface of the installation mechanism 1, the clamping mechanism 2 including a displacement plate component 21 disposed on the surface of the installation mechanism 1, a clamping component 22 mounted on the surface of the displacement plate component 21, the clamping component 22 including a gripper assembly 221, the surface of the gripper assembly 221 contacting the surface of the displacement plate component 21, and a clamping plate drive assembly 222 installed inside the gripper assembly 221; Specifically, the displacement plate component 21 is set on the surface of the mounting mechanism 1 and is a key link connecting the external power and the action of the gripper. In the initial state, the displacement plate component 21 is in the standby position on the surface of the mounting mechanism 1. At this time, the gripper assembly 221 of the clamping component 22 is in the open state. When the equipment receives the clamping command, the displacement plate component 21 pushes it to slide smoothly along the preset path on the surface of the mounting mechanism 1.

[0024] Please see the appendix Figure 3 To be continued Figure 5The mounting mechanism 1 includes a base plate component 11, the surface of which contacts the surface of the clamping mechanism 2. A driving component 12 is mounted on the surface of the base plate component 11, and a buffer component 13 is provided on the surface of the base plate component 11. The base plate component 11 includes a mounting plate 111, with a rotating shaft 112 fixedly connected to the inner wall of the mounting plate 111, and a limit plate 113 fixedly connected to the outer surface of the mounting plate 111. The driving component 12 includes a cover box 121, the outer surface of which is fixed to the outer surface of the mounting plate 111, and the inner wall of the cover box 121... A drive push rod 122 is fixedly connected, and a shrink block 123 is fixedly connected to the end of the drive push rod 122. The outer surface of the shrink block 123 slides against the inner wall of the mounting plate 111. The buffer component 13 includes a pad 131. The outer surface of the pad 131 contacts the outer surface of the mounting plate 111. A sliding column 133 is slidably connected to the inner wall of the pad 131. A buffer arc plate 132 is fixedly connected to the end of the sliding column 133. A buffer spring 134 is fixedly connected to the inner wall of the pad 131. The end of the buffer spring 134 is fixed to the end of the sliding column 133. Specifically, the mounting plate 111 serves as the basic carrier, and its surface contacts the surface of the clamping mechanism 2. The rotating shaft 112, which is fixedly connected to the inner wall, directly serves as the rotation fulcrum of the jaw assembly 221 in the subsequent clamping mechanism 2, ensuring that the jaw can smoothly open and close around the rotating shaft 112 along a preset trajectory, avoiding movement deviation. The buffer arc plate 132 first contacts the pipe, and the pressure generated by the pipe on the buffer arc plate 132 is transmitted to the sliding column 133, pushing the sliding column 133 to slide inward along the inner wall of the pad 131. At this time, the buffer spring 134, which is fixedly connected to the inner wall of the pad 131, is compressed. The rigid impact force of the jaw closing is absorbed by the spring deformation, preventing the pipe from being dented or scratched due to hard contact.

[0025] Please see the appendix Figure 3 The displacement plate component 21 includes a connecting plate 211, an expansion shaft 213 fixedly connected to the outer surface of the connecting plate 211, a connecting rod 212 hinged to the inner wall of the connecting plate 211, the outer surface of the connecting rod 212 sliding against the inner wall of the sliding column 133, the outer surface of the expansion shaft 213 sliding against the inner wall of the limiting plate 113, and a column shaft 214 fixedly connected to the inner wall of the connecting plate 211. Specifically, the connecting plate 211 is the main frame of the displacement plate component 21. Its outer surface is in contact with the surface of the mounting plate 111 of the mounting mechanism 1. At the same time, it serves as the direct mounting carrier for the connecting rod 212, the expansion shaft 213, and the column shaft 214. When the retracting block 123 of the driving component 12 transmits thrust, the connecting plate 211 first receives the power and evenly distributes the power to the subordinate components to avoid localized force causing the action to stall.

[0026] Please see the appendix Figure 6 and attached Figure 7The gripper assembly 221 includes a primary gripper 2211, the inner wall of which rotates with the outer surface of the rotating shaft 112, the outer surface of the primary gripper 2211 with the outer surface of the column shaft 214, and the outer surface of the primary gripper 2211 with the inner walls of the mounting plate 111 and the connecting plate 211. A connecting shaft 2212 is rotatably connected to the inner wall of the primary gripper 2211, and a secondary gripper 2213 is fixedly connected to the outer surface of the connecting shaft 2212. The outer surface is movably connected to the outer surface of the connecting shaft 2212. The clamping plate drive assembly 222 includes a connecting plate 2221. The outer surface of the connecting plate 2221 is fixed to the outer surface of the first-stage clamp 2211. A fixing block 2222 is fixedly connected to the outer surface of the connecting plate 2221. A clamping plate push rod 2223 is fixedly connected to the inner wall of the fixing block 2222. An expansion block 2224 is fixedly connected to the end of the clamping plate push rod 2223. The inner wall of the expansion block 2224 is fixed to the outer surface of the connecting shaft 2212.

[0027] Specifically, when the connecting plate 211 of the displacement plate component 21 moves towards the pipe fitting, the column shaft 214 moves linearly and synchronously with the connecting plate 211. Since the column shaft 214 is rotatably connected to the inner wall of the first-stage gripper 2211, the displacement of the column shaft 214 will exert a thrust on the first-stage gripper 2211 around the rotating shaft 112. Under the action of the thrust, the first-stage gripper 2211 rotates inward with the rotating shaft 112 as a fixed fulcrum, and the two first-stage grippers 2211 on both sides close synchronously until the buffer arc plate 132 on its inner side is in contact with the surface of the pipe fitting, completing the initial clamping and positioning of the pipe fitting. The outer surface of the connecting shaft 2212 and the second-stage gripper... Plate 2213 is fixedly connected, and the rotation of shaft 2212 will drive the secondary clamping plate 2213 to rotate towards the pipe. Since the rotation angle of the secondary clamping plate 2213 is controlled by the extension of the clamping plate push rod 2223, and its inner wall is arc-shaped, the degree of fit can be flexibly adjusted according to the pipe diameter. If the pipe diameter is large, the secondary clamping plate 2213 can fit with a small angle rotation. If the diameter is small, the push rod continues to extend, driving the secondary clamping plate 2213 to rotate with a larger angle until it is completely fitted to the pipe surface. This process achieves adaptive fine clamping, which not only enhances clamping stability but also avoids over-clamping and damage to the pipe.

[0028] Working principle: Before the equipment starts, it is in the initial reset state. The drive push rod 122 of the drive component 12 and the clamping push rod 2223 of the clamping plate drive assembly 222 are fully retracted. Multiple symmetrically distributed first-stage grippers 2211 are in an open state. The buffer springs 134, which are evenly distributed in the buffer components 13 at both ends of the grippers, maintain their natural length. The sliding column 133 drives the buffer arc plate 132 to extend. The connecting plate 211 of the displacement plate component 21 is in the initial position within the limiting plate 113 through the expansion shaft 213. After receiving the clamping command, the drive push rod 122 extends and pushes the retracting block 123 to slide along the inner wall of the mounting plate 111, driving the connecting plate 211 to move. The connecting rod 212 on the inner wall of the connecting plate 211 slides relative to the sliding column 133. At the same time, the column shaft 214 on the connecting plate 211 drives multiple first-stage grippers 2211. The rotating shaft 112 closes synchronously inward, expanding the radial coverage range to achieve multi-point positioning until the buffer arc plate 132 contacts the pipe fitting. The pipe fitting pushes the sliding column 133 to compress the buffer spring 134 to absorb the impact and balance the force to prevent the pipe fitting from tilting. After the first-stage clamp 2211 completes the initial closing positioning, the clamping plate push rod 2223 extends to push the expansion block 2224, causing the connecting shaft 2212 to drive the second-stage clamping plate 2213 to rotate around the inner wall of the first-stage clamp 2211. The size of the pipe fitting is adapted to fit tightly in the gap on the inner side of the first-stage clamp 2211 to form a double-layer contact inside and outside, which strengthens friction and prevents the pipe fitting from sliding. Then, the pipe fitting is hoisted with the external equipment through the reserved interface of the mounting plate 111. The buffer spring 134 continuously offsets the vibration of transportation. The multi-point coverage of the first-stage clamp 2211 and the fine clamping of the second-stage clamping plate 2213 are linked to prevent the pipe fitting from sliding sideways.
