[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 12As shown, the present invention provides a quick-assembly stainless steel pipe hanger, including an installation arm 1, with gripping structures 2 at both ends of the installation arm 1, an adjustment structure 3 connected between the gripping structures 2 and the installation arm 1, a fixing structure 6 on the inner side of the gripping structures 2, a release structure 4 connected between the fixing structure 6 and the installation arm 1, a positioning structure 7 connected between the adjustment structure 3 and the installation arm 1, and a lifting structure 5 connected to the gripping structures 2.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the gripping structure 2 includes a gripping head 201. A gripping head 201 is provided at each end of the mounting arm 1. An arc-shaped slide rod 202 is slidably connected to both sides of the gripping head 201. A gripping rod 203 is rotatably connected to the middle of the arc-shaped slide rod 202. An arc-shaped connecting slide rod 204 is fixedly connected to the middle of the arc-shaped slide rod 202. The gripping rod 203 and the connecting slide rod 204 are slidably connected. A first spring 205 is fixedly connected between the end of the gripping rod 203 and the arc-shaped slide rod 202. For stainless steel pipes placed on the ground, if the vertical distance between the ends of the two gripping rods 203 is less than the diameter of the steel pipe, the user can directly press the device down from the top side of the steel pipe. When the gripping rods 203 pass over the steel pipe, they will automatically retract and then extend again to grip the steel pipe. At this time, fixing the position of the gripping rods 203 will complete the gripping of the steel pipe. There is no need for the operator to manually perform the loading operation between the steel pipe and the lifting device, thus improving the operating efficiency.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 9 , Figure 12As shown, the adjustment structure 3 includes an inner slide rod 305. Two inner slide rods 305 are parallel to each other in the middle of the mounting arm 1. The inner slide rods 305 are rotatably connected to the mounting arm 1. A worm gear sleeve 306 is fixedly connected to the middle of the inner slide rod 305. An adjusting worm 301 is rotatably connected to the side of the mounting arm 1. The adjusting worm 301 meshes with both worm gear sleeves 306. A telescopic sleeve 302 is slidably connected to each end of the inner slide rod 305. The end of the telescopic sleeve 302 is rotatably connected to the gripping head 201 on the same side. The end of the telescopic sleeve 302 is provided with a first tooth groove 303. The two sides of the arc-shaped slide rod 202 are provided with second tooth grooves 304. The end of the telescopic sleeve 302 meshes with the second tooth grooves 304 on the arc-shaped slide rod 202 on the same side through the first tooth groove 303. For easy adjustment, the telescopic sleeve 302 is slidably connected to the inner slide rod 305 in the middle of the mounting arm 1. The user can rotate the adjusting worm gear 301 located on the side of the mounting arm 1, which will drive the two telescopic sleeves 302 to rotate synchronously through the worm gear sleeve 306, thereby adjusting the distance between the gripping rods 203. On the other hand, since the inner slide rod 305 and the telescopic sleeve 302 can slide, the user can adjust the distance between the two gripping heads 201 according to the length of the pipe to be lifted, making the pipe more stable during transportation.

[0027] Specifically, such as Figure 2 , Figure 4 , Figure 6 , Figure 8 As shown, the fixing structure 6 includes a positioning groove 607. The inner side of the arc-shaped slide rod 202 is provided with a positioning groove 607. A positioning block 605 is slidably connected to each side of the gripping rod 203. The end of the positioning block 605 is engaged with the arc-shaped slide rod 202 through the positioning groove 607. A fourth spring 606 is fixedly connected between the two positioning blocks 605. The side of the two positioning blocks 605 that is close to each other is a slope structure. A slope block 604 is abutted between the two positioning blocks 605 through the slope. The slope block 604 is slidably connected to the inner side of the gripping rod 203. An arc-shaped block 601 is slidably connected to the inner side of the gripping head 201. A third spring 602 is fixedly connected between the top side of the arc-shaped block 601 and the gripping head 201. Two arc grooves 603 are provided on the inner side of the arc-shaped block 601. The top of the slope block 604 is a hemispherical structure. The spherical end of the slope block 604 abuts against the inner side of the arc-shaped block 601. Because a first spring 205 connects the gripping rod 203 and the arc-shaped sliding rod 202, the pipe may come loose if it is too heavy after being gripped by the gripping rod 203. To facilitate gripping and lifting the pipe by the gripping rod 203, positioning blocks 605 are provided on both sides of the gripping rod 203. The positioning blocks 605 engage with the arc-shaped sliding rod 202 through positioning grooves 607, preventing the gripping rod 203 from retracting. Once the gripping rod 203 has successfully gripped the pipe, the entire lifting device can be lifted. The gripping rod 203 can remain fixed to prevent the pipe from coming loose. When gripping the pipe, the arc surface located inside the gripping head 201 needs to be slid. Block 601 is positioned so that the arc groove 603 on the inner side of the arc block 601 is aligned with the spherical end of the inclined block 604. At this time, under the traction of the fourth spring 606 between the two positioning blocks 605, the positioning block 605 disengages from the positioning groove 607, thereby releasing the fixed state of the grab rod 203. At this time, the pipe on the ground can be grabbed by the grab rod 203. The spherical end of the inclined block 604 will abut against the arc block 601 through the arc groove 603. Since the arc groove 603 has an arc-shaped structure, the sliding position of the arc-shaped slide rod 202 will not affect the release effect of the grab rod 203. After the grab is completed, the arc block 601 is released to reset, and the grab rod 203 can be fixed again, which facilitates the transportation of the pipe.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 12 As shown, the release structure 4 includes a telescopic rotary rod 403. The gripping head 201 is rotatably connected to the side of the mounting arm 1 with the telescopic rotary rod 403. The end of the telescopic rotary rod 403 is rotatably connected to the arc block 601. A sliding column 404 is fixedly connected to the side of the end of the telescopic rotary rod 403. A torsion groove 406 is provided on the inner side of the arc block 601. The sliding column 404 is slidably connected to the arc block 601 through the torsion groove 406. A limit groove 405 is provided in the middle of the mounting arm 1. A release rod 401 is rotatably connected to the middle of the mounting arm 1 through the limit groove 405. A transmission sleeve 402 is fixedly connected to each end of the release rod 401. The transmission sleeve 402 is slidably connected to the telescopic rotary rod 403 on the same side. To facilitate control over the fixing state of the gripping rod 203, a telescopic rotating rod 403 slides on one side of the arc-shaped block 601. The telescopic rotating rod 403 is rotatably connected to the gripping head 201 on the same side. When it is necessary to push the arc-shaped block 601 to release the gripping rod 203, the user can turn the release rod 401 inside the limiting groove 405 in the middle of the mounting arm 1 to the other side. At this time, the transmission effect of the transmission sleeve 402 can simultaneously drive the telescopic rotating rods 403 on both sides to rotate. At this time, the sliding column 404 at the end of the telescopic rotating rod 403 will slide in the torsion groove 406 opened on the arc-shaped block 601 on the same side. The structure of the torsion groove 406 will drive the arc-shaped block 601 to slide to one side, thereby releasing the fixing effect of the gripping rods 203 on both sides through the fixing structure 6. At this time, the pipe can be gripped. After the gripping is completed, the release rod 401 can be released to fix the gripping rod 203 again.

[0029] Specifically, such as Figure 5 , Figure 9 , Figure 11 , Figure 12 As shown, the positioning structure 7 includes a fixing block 703. A fixing block 703 is fixedly connected to each side of the mounting arm 1. Two abutting blocks 707 are slidably connected to the bottom side of the fixing block 703. A sixth spring 708 is fixedly connected between the abutting block 707 and the fixing block 703. Multiple positioning ring grooves 702 are opened at equal intervals on the outer side of the telescopic sleeve rod 302. The bottom end of the abutting block 707 abuts against the telescopic sleeve rod 302 through the positioning ring groove 702. A control rod 701 is slidably connected to the side of the mounting arm 1. A misalignment block 704 is fixedly connected to each end of the control rod 701. A fifth spring 705 is fixedly connected between the misalignment block 704 and the fixing block 703. An abutting groove 706 is opened on the bottom side of the misalignment block 704. The top end of the abutting block 707 abuts against the bottom side of the misalignment block 704. The inner sliding rod 305, the telescopic sleeve rod 302, the telescopic rotating rod 403, and the transmission sleeve 402 allow the user to adjust the distance between the two gripping heads 201 according to the length of the pipe to be lifted. To facilitate control of the overall length adjustment of the lifting device, multiple positioning ring grooves 702 are equidistantly provided on the outer side of the telescopic sleeve rod 302. A misalignment block 704 is provided on the top side of the contact block 707. When the user presses the control lever 701 to slide the misalignment block 704 inwards, due to the misalignment... The abutment groove 706 on the bottom side of the positioning block 704 provides space for the sliding of the abutment block 707. The abutment block 707 will achieve the positioning effect through the abutment action with the positioning ring groove 702, so that the user can freely adjust the overall telescopic length of the lifting device. After the adjustment is completed, the control rod 701 is released. At this time, the abutment groove 706 on the bottom side of the misalignment block 704 is misaligned with the abutment block 707. At this time, the position of the abutment block 707 is fixed, so that the lifting device can maintain the current telescopic length and ensure stability during use.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 As shown, the lifting structure 5 includes a winding shaft 503, the top side of the gripping head 201 is rotatably connected to the winding shaft 503, the middle part of the winding shaft 503 is fixedly connected to the traction rope 501, the other ends of the two traction ropes 501 are fixedly connected to the suspension block 502, the end of the winding shaft 503 is provided with a ratchet groove 505, the inner side of the gripping head 201 is slidably connected to a ratchet block 506, the ratchet block 506 and the gripping head 201 are fixedly connected to a second spring 507, the end of the ratchet block 506 is engaged with the winding shaft 503 through the ratchet groove 505, the top side of the gripping head 201 is slidably connected to a pushing block 504, the bottom end of the pushing block 504 is in contact with the ratchet block 506; To enhance the lifting strength of the lifting device when lifting steel pipes, a winding shaft 503 is installed on the gripping heads 201 at both ends. The ends of the traction ropes 501 extending from the two winding shafts 503 are connected to the suspension blocks 502 in the middle. The suspension blocks 502 pull the entire lifting device, which optimizes the direction of force transmission and increases the strength of the lifting device. At the same time, depending on the extension length of the lifting device, the user can press the push block 504 located on the top side of the gripping head 201 to disengage the ratchet block 506 from the ratchet groove 505 on the winding shaft 503, thereby adjusting the length of the traction rope 501. After the adjustment is completed, the push block 504 is released. Due to the restriction of the ratchet groove 505, the extension length of the forward extension is fixed, thus achieving a stable traction effect.

[0031] In use, this invention firstly has a gripping head 201 at each end of the mounting arm 1 for gripping stainless steel pipes. An arc-shaped sliding rod 202 is located on each side of the gripping head 201, and a gripping rod 203 is further provided inside the arc-shaped sliding rod 202. A first spring 205 connects the gripping rod 203 and the arc-shaped sliding rod 202, allowing the gripping rod 203 to automatically return to its extended state. For stainless steel pipes placed on the ground, if the vertical distance between the ends of the two gripping rods 203 is less than the diameter of the pipe, the user can directly press the device down from the top of the pipe. As the gripping rod 203 passes over the pipe, it automatically retracts and then extends again, thus gripping the pipe. At this time, the position of the gripping rod 203 is fixed. The device can grip steel pipes instantly without requiring manual loading between the pipe and the lifting device, thus improving operational efficiency. A telescopic sleeve 302 is located on the side of the gripping head 201. The end of the telescopic sleeve 302 engages with an arc-shaped sliding rod 202 on the same side via a first toothed groove 303 and a second toothed groove 304. This changes the extension length of the arc-shaped sliding rod 202 and the gripping rod 203 when the telescopic sleeve 302 rotates, facilitating the gripping of pipes of different diameters. For easy adjustment, the telescopic sleeve 302 is slidably connected to an inner sliding rod 305 located in the middle of the mounting arm 1. The user can rotate the adjusting worm gear 301 located on the side of the mounting arm 1, which, through the worm gear sleeve 306, simultaneously drives both telescopic sleeves 302. 2. Synchronous rotation is performed to adjust the distance between the gripping rods 203. On the other hand, since the inner sliding rod 305 and the telescopic sleeve rod 302 can slide, the user can adjust the distance between the two gripping heads 201 according to the length of the pipe to be lifted, making the pipe more stable during transportation. Because a first spring 205 connects the gripping rod 203 and the arc-shaped sliding rod 202, if the pipe is too heavy after being gripped by the gripping rod 203, it may detach. To facilitate gripping and lifting the pipe by the gripping rod 203, positioning blocks 605 are provided on both sides of the gripping rod 203. The positioning blocks 605 engage with the arc-shaped sliding rod 202 through positioning grooves 607, preventing the gripping rod 203 from retracting. Once the gripping rod 203 has successfully gripped the pipe, the entire lifting device can be lifted. The gripping rod 203 can remain fixed to prevent the pipe from coming out. When gripping the pipe, the arc-shaped block 601 located inside the gripping head 201 needs to be slid, so that the arc groove 603 on the inner side of the arc-shaped block 601 is aligned with the spherical end of the inclined block 604. At this time, under the traction of the fourth spring 606 between the two positioning blocks 605, the positioning blocks 605 disengage from the positioning groove 607, thus releasing the fixing state of the gripping rod 203. Now, the gripping rod 203 can grip the pipe on the ground. The spherical end of the inclined block 604 will abut against the arc-shaped block 601 through the arc groove 603. Since the arc groove 603 has an arc-shaped structure...This ensures that the sliding position of the arc-shaped slide bar 202 does not affect the release effect on the gripper bar 203. After gripping, the arc-shaped block 601 is released to reset, thus re-fixing the gripper bar 203 and facilitating pipe transportation. To facilitate control of the fixed state of the gripper bar 203, a telescopic rotating rod 403 slides on one side of the arc-shaped block 601. The telescopic rotating rod 403 is rotatably connected to the gripper head 201 on the same side. When it is necessary to push the arc-shaped block 601 to release the gripper bar 203, the user can turn the release rod 401 inside the limiting groove 405 in the middle of the mounting arm 1 to the other side. At this time, the transmission effect of the transmission sleeve 402 can simultaneously drive the telescopic rotating rods 403 on both sides to rotate. The sliding column 404 at the end of the rod 403 slides within the torsion groove 406 on the arc block 601 on the same side. The structure of the torsion groove 406 causes the arc block 601 to slide to one side, thereby releasing the fixing effect of the two gripping rods 203 simultaneously through the fixing structure 6. At this time, the pipe can be gripped. After gripping, releasing the release rod 401 can re-fix the gripping rod 203. Through the setting of the inner sliding rod 305, the telescopic sleeve rod 302, the telescopic rotating rod 403, and the transmission sleeve 402, the user can adjust the distance between the two gripping heads 201 according to the length of the pipe to be lifted. In order to facilitate the adjustment of the overall length of the lifting device, the outer side of the telescopic sleeve rod 302 is equidistantly positioned. Multiple positioning ring grooves 702 are provided, and a misalignment block 704 is located on the top side of the contact block 707. When the user presses the control lever 701 to slide the misalignment block 704 inward, the contact groove 706 on the bottom side of the misalignment block 704 provides space for the sliding of the contact block 707. The contact block 707 will achieve a positioning effect through the contact action with the positioning ring grooves 702, allowing the user to freely adjust the overall telescopic length of the lifting device. After the adjustment is completed, the control lever 701 is released. At this time, the contact groove 706 on the bottom side of the misalignment block 704 is misaligned with the contact block 707, and the position of the contact block 707 is fixed, so that the lifting device can maintain the current telescopic length and ensure stability during use. In order to improve the lifting... The lifting device is designed to enhance its strength when lifting steel pipes. At both ends, the gripping heads 201 are equipped with retractable shafts 503. The ends of the traction ropes 501 extending from the two retractable shafts 503 are connected to the suspension blocks 502 in the middle. The suspension blocks 502 provide overall traction to the lifting device, optimizing the force transmission direction and increasing its strength. Simultaneously, depending on the extension length of the lifting device, the user can press the push block 504 located on the top side of the gripping head 201 to disengage the ratchet block 506 from the ratchet groove 505 on the retractable shaft 503, allowing adjustment of the length of the traction rope 501. After adjustment, releasing the push block 504, due to the restriction of the ratchet groove 505, fixes the extension length of the forward extension, thus achieving a stable traction effect.
