[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1 to 3As shown, a quick-clamping pipe clamp according to one embodiment of the present invention includes a frame 1, a base 2 mounted on the frame 1, a fixing block 23 mounted on the top plate of the base 2, a clamping block 24 provided on the end face of the fixing block 23 away from the base 2, a clamping part is formed between the fixing block 23 and the clamping block 24 of the base 2, and the quick-clamping pipe clamp also includes a clamping component for controlling the size of the clamping part.

[0031] Specifically, the clamping part formed between the base 2, the fixing block 23, and the clamping block 24 can clamp the pipe from all directions, fixing the pipe within the clamping part. At the same time, by changing the size of the clamping part through the clamping assembly, the clamping part can clamp the pipe without applying additional pressure, preventing the pipe from deforming or being damaged due to excessive clamping force.

[0032] Specifically, the clamping assembly includes a cylinder 22, which is mounted on the lower plate of the base 2. A lifting rod 221 is welded to the piston rod of the cylinder 22, and the lifting rod 221 passes through the base 2 and the fixing block 23. A threaded hole 2211 is opened on the end face of the lifting rod 221 away from the cylinder 22. A screw 241 is provided on the clamping block 24. The part of the screw 241 that passes through the clamping block 24 is not threaded, and the end of the screw 241 that passes through the clamping block 24 is threaded into the threaded hole 2211. A retaining ring 2411 is integrally formed on the clamping block 24. The retaining ring 2411 is rotatably connected to the clamping block 24, and the retaining ring 2411 ensures that the position of the screw 241 on the clamping block 24 does not change.

[0033] Specifically, the reciprocating motion of the piston rod on cylinder 22 allows the clamping block 24 to move away from or closer to the base 2, thereby changing the size of the clamping section. Furthermore, by rotating the screw 241, the length of the screw 241 entering the threaded hole 2211 can be controlled, adjusting the distance between the clamping block 24 and the base 2 so that the distance between them matches the pipe size. When the piston on cylinder 22 is fully retracted, the clamping block 24 presses precisely against the pipe within the clamping section, clamping the pipe tightly without applying additional pressure. This ensures the pipe is clamped while protecting it from damage.

[0034] Furthermore, the base 2 has a clamping surface 21 that matches the clamping part, and a cavity 211 is formed inside the base 2. Specifically, the clamping surface 21 is an arc-shaped surface. Because the cavity 211 is formed inside the base 2, the upper surface of the base 2 becomes elastic. When the pipe is placed on the clamping surface 21, the cylinder 22 is activated, and the piston rod of the cylinder 22 retracts into the cylinder 22. The clamping block 24 presses on the pipe. At this time, the elastic base 2 can undergo slight deformation, dispersing the pressure on the pipe and further protecting the pipe. At the same time, because the clamping surface 21 is an arc-shaped surface, the pressure between the pipe and the clamping surface 21 can be reduced, further protecting the pipe.

[0035] It is worth noting that when placing or removing pipes, the pipes need to be continuously lifted to prevent friction between the pipes and the clamping surface 21 from scratching the pipe surface. However, some pipes are quite long, making lifting them difficult and hindering normal production.

[0036] To solve the above problems, such as Figures 4 to 8 As shown, a roller 3 matching the clamping part is installed inside the cavity 211, and an opening 212 matching the roller 3 is provided on the clamping surface 21. Specifically, when placing or removing the pipe, the roller 3 can enter the clamping part through the opening 212, lift the pipe on the cavity 211, and push the pipe when picking up or placing it. The rotation of the roller 3 can make the pipe enter or move out of the clamping part.

[0037] To allow the roller 3 to enter the clamping part, a lifting assembly is installed in the cavity 211. The lifting assembly is used to lift the roller 3 inside the cavity 211. The lifting assembly includes a pair of fixed plates 4, which are welded into the cavity 211. A lifting block 42 is slidably connected to the fixed plates 4, and a bearing 43 is embedded in the lifting block 42. A roller 31 that matches the bearing 43 is integrally formed on the roller 3. The end of the roller 31 away from the roller 3 is inserted into the rotating inner ring of the bearing 43 and is interference-fitted with the rotating inner ring of the bearing 43. When the roller 3 rotates, the bearing 43 rotates on the lifting block 42. By sliding the lifting block 42 on the fixed plates 4, the roller 3 can be driven to rise or fall.

[0038] Specifically, a through groove 41 is provided on the fixed plate 4, and the lifting block 42 is slidably connected in the through groove 41. A spring 44 is welded to the lower plate of the lifting block 42, and the end of the spring 44 away from the lifting block 42 is welded to the bottom wall of the through groove 41. When it is necessary to pick up or place the pipe, the clamping block 24 rises away from the base 2, and the spring 44 can push the roller 3 out of the cavity 211 and make it enter the clamping part. At this time, the exposed surface of the roller 3 is higher than the clamping surface 21. Pushing or pulling the pipe will cause the roller 3 to rotate, so even without lifting the pipe, friction between the pipe and the clamping surface 21 can be prevented.

[0039] During clamping, the piston rod on cylinder 22 retracts, and clamping block 24 moves downward, gradually pressing on the pipe. The pipe will press on roller 3, and the pressure on roller 3 will be transmitted to lifting block 42. Lifting block 42 presses down on spring 44, spring 44 deforms elastically, and lifting block 42 slides downward in through groove 41. Roller 3 can then retract into cavity 211 without affecting the clamping of pipe.

[0040] Furthermore, a sliding groove 411 is provided on the opposite wall of the through groove 41, and a slide rail 421 that matches the sliding groove 411 is integrally formed on the lifting block 42. The sliding groove 411 and the slide rail 421 cooperate with each other to prevent the lifting block 42 from deflecting, so that the lifting block 42 can move vertically within the through groove 41.

[0041] Furthermore, because the roller 3 and the pipe are in line contact, to prevent damage to the pipe due to pressure between them, a connecting plate 422 is welded to the lifting block 42, and a pressure plate 222 matching the connecting plate 422 is welded to the lifting rod 221. Specifically, when the piston rod on the cylinder 22 retracts, the lifting rod 221 moves downward. At this time, the pressure plate 222 first presses against the connecting plate 422, which then drives the lifting block 42 to move downward, thereby allowing the roller 3 to enter the cavity 211. This prevents the pressure of the lifting block 42 on the pipe from pressing onto the roller 3.

[0042] In addition, the roller 3 is covered with a protective layer 32, which is a soft protective layer, preferably a sponge layer, to further protect the pipe.

[0043] In use, first adjust the distance between the clamping block 24 and the base 2 to match the size of the pipe. Place the pipe into the clamping part, start the cylinder 22, the piston rod on the cylinder 22 retracts, and the clamping block 24 gradually moves closer to the base 2, thus clamping the pipe and fixing it.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
