[0035] 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.

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 12 The application discloses a stainless steel pipe hanger capable of being quickly assembled, which comprises a mounting arm 1, a grabbing structure 2 arranged at both ends of the mounting arm 1, an adjusting structure 3 connected between the grabbing structure 2 and the mounting arm 1, a fixing structure 6 arranged at the inner side of the grabbing structure 2, a releasing structure 4 connected between the fixing structure 6 and the mounting arm 1, a positioning structure 7 connected between the adjusting structure 3 and the mounting arm 1, and a lifting structure 5 connected with the grabbing structure 2.

[0037] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 The grabbing structure 2 comprises a grabbing head 201, one grabbing head 201 is arranged at each end of the mounting arm 1, arc-shaped sliding rods 202 are slidably connected to the two sides of the grabbing head 201, a grabbing rod 203 is rotatably connected to the middle part of the arc-shaped sliding rod 202, an arc-shaped connecting sliding rod 204 is fixedly connected to the middle part of the arc-shaped sliding rod 202, the grabbing rod 203 is slidably connected with the connecting sliding rod 204, and a first spring 205 is fixedly connected between the end part of the grabbing rod 203 and the arc-shaped sliding rod 202.

[0038] For the stainless steel pipe placed on the ground, if the vertical distance between the two end parts of the grabbing rod 203 is smaller than the diameter of the steel pipe, the device can be directly pressed down from the top side of the steel pipe, the grabbing rod 203 can be automatically retracted and then extended when the grabbing rod 203 passes through the steel pipe, the grabbing of the steel pipe is realized, and the position of the fixed grabbing rod 203 can be fixed to complete the grabbing of the steel pipe, so that the loading operation between the steel pipe and the lifting device is not needed to be manually operated, and the operation efficiency is improved.

[0039] Specifically, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 9 , Figure 12As shown, the adjusting structure 3 includes inner slide rods 305, two inner slide rods 305 are arranged in parallel in the middle of the mounting arm 1, the inner slide rods 305 are rotatably connected with the mounting arm 1, the middle of the inner slide rods 305 is fixedly connected with worm gear sleeves 306, the side of the mounting arm 1 is rotatably connected with adjusting worms 301, the adjusting worms 301 are engaged with the two worm gear sleeves 306 at the same time, the two ends of the inner slide rods 305 are slidably connected with one telescopic sleeve rod 302 respectively, the end of the telescopic sleeve rod 302 is rotatably connected with the grabbing head 201 arranged on the same side, the end of the telescopic sleeve rod 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 rod 302 is engaged with the second tooth grooves 304 on the arc-shaped slide rod 202 arranged on the same side through the first tooth groove 303;

[0040] In order to facilitate adjustment, the telescopic sleeve rod 302 is slidably connected with the inner slide rod 305 arranged in the middle of the mounting arm 1, the user can rotate the adjusting worm 301 arranged on the side of the mounting arm 1, drive the two telescopic sleeve rods 302 to rotate synchronously through the worm gear sleeve 306, and then adjust the distance between the grabbing rods 203, on the other hand, since the inner slide rod 305 can slide with the telescopic sleeve rod 302, the user can adjust the distance between the two grabbing heads 201 according to the length of the pipe to be lifted, so that the pipe is more stable during transportation.

[0041] Specifically, as shown in Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 The fixing structure 6 includes positioning grooves 607, the inner side of the arc-shaped slide rod 202 is provided with the positioning grooves 607, one positioning block 605 is slidably connected to the two sides of the grabbing rod 203 respectively, the end of the positioning block 605 is clamped between the arc-shaped slide rod 202 through the positioning groove 607, the fourth spring 606 is fixedly connected between the two positioning blocks 605, one side of the two positioning blocks 605 close to each other is a slope structure, the slope block 604 is in contact with the two positioning blocks 605 through the slope, the slope block 604 is slidably connected to the inner side of the grabbing rod 203, the arc block 601 is slidably connected to the inner side of the grabbing head 201, the third spring 602 is fixedly connected between the top side of the arc block 601 and the grabbing head 201, the inner side of the arc block 601 is provided with two arc grooves 603, the top end of the slope block 604 is a hemispherical structure, the spherical end of the slope block 604 is in contact with the inner side of the arc block 601;

[0042] The first spring 205 is connected between the grabbing lever 203 and the arc-shaped sliding rod 202, so that when the grabbing lever 203 is used to grab the pipe, if the pipe is too heavy, the pipe will be pulled out. In order to facilitate the grabbing and lifting of the pipe by the grabbing lever 203, the two sides of the grabbing lever 203 are provided with positioning blocks 605, and the positioning blocks 605 are clamped between the arc-shaped sliding rod 202 and the positioning grooves 607, so that the grabbing lever 203 cannot be retracted at this time. If the grabbing lever 203 has completed the grabbing of the pipe at this time, the whole lifting device can be lifted, and the grabbing lever 203 can always maintain a fixed state to avoid the pipe from being pulled out. When the pipe needs to be grabbed, the arc block 601 inside the grabbing head 201 needs to be slid, so that the arc groove 603 inside 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 blocks 605 are separated from the positioning grooves 607, that is, the fixed state of the grabbing lever 203 is released. At this time, the pipe on the ground can be grabbed by the grabbing lever 203, and 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 is in an arc-shaped structure, the sliding position of the arc-shaped sliding rod 202 will not affect the release effect of the grabbing lever 203. After the grabbing is completed, the arc block 601 is released and reset, and the grabbing lever 203 can be fixed again, which is convenient for the transportation of the pipe.

[0043] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 12 The release structure 4 includes a telescopic rotary rod 403, and the side close to the mounting arm 1 of the grabbing head 201 is rotationally connected with the telescopic rotary rod 403. The end of the telescopic rotary rod 403 is rotationally connected with the arc block 601, and the side surface of the end of the telescopic rotary rod 403 is fixedly connected with a sliding column 404. The inner side of the arc block 601 is provided with a torsion groove 406, and the sliding column 404 is slidably connected with the arc block 601 through the torsion groove 406. The middle part of the mounting arm 1 is provided with a limiting groove 405, and the middle part of the mounting arm 1 is rotationally connected with a release rod 401 through the limiting groove 405. The two ends of the release rod 401 are respectively fixedly connected with a transmission sleeve 402, and the transmission sleeve 402 is slidably connected with the telescopic rotary rod 403 on the same side.

[0044] In order to conveniently control the fixed state of the grab rod 203, the side of the arc block 601 is slidably connected with the telescopic rotating rod 403, and the telescopic rotating rod 403 is rotationally connected with the grabbing head 201 on the same side. When it is needed to push the arc block 601 to release the grab rod 203, the user can turn the release rod 401 in the middle limiting groove 405 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 slide column 404 arranged at the end of the telescopic rotating rod 403 can slide in the torsion groove 406 arranged on the arc block 601 on the same side. The structure of the torsion groove 406 can drive the arc block 601 to slide to one side, so as to simultaneously release the fixing effect of the grab rod 203 on both sides through the fixing structure 6. At this time, the pipe can be grabbed. After the grabbing is completed, the release rod 401 is released, and the grab rod 203 can be fixed again.

[0045] Specifically, as shown in Figure 5 、 Figure 9 、 Figure 11 、 Figure 12 The positioning structure 7 includes the fixed block 703. The two sides of the mounting arm 1 are fixedly connected with one fixed block 703, respectively. The bottom side of the fixed block 703 is slidably connected with two abutting blocks 707. The abutting block 707 is fixedly connected with the sixth spring 708 between the fixed block 703. The outer side of the telescopic sleeve rod 302 is sequentially and equidistantly provided with a plurality of positioning ring grooves 702. The bottom end of the abutting block 707 abuts against the telescopic sleeve rod 302 through the positioning ring groove 702. The side surface of the mounting arm 1 is slidably connected with the control rod 701. The two ends of the control rod 701 are fixedly connected with one offset block 704, respectively. The offset block 704 is fixedly connected with the fifth spring 705 between the fixed block 703. The bottom side of the offset block 704 is provided with the abutting groove 706. The top end of the abutting block 707 abuts against the bottom side of the offset block 704.

[0046] The inner slide rod 305, the telescopic sleeve rod 302, the telescopic rotary rod 403 and the transmission sleeve 402 are arranged, so that the user can adjust the distance between the two grabbing heads 201 according to the length of the pipe to be lifted. In order to conveniently control the adjustment of the overall length of the lifting device, a plurality of positioning ring grooves 702 are sequentially and equidistantly arranged on the outer side of the telescopic sleeve rod 302, and a staggered block 704 is arranged on the top side of the abutting block 707. When the user presses the control rod 701 to make the staggered block 704 slide inward, because the abutting groove 706 on the bottom side of the staggered block 704 provides space for the sliding of the abutting block 707, the abutting block 707 can play a positioning effect through the abutting action between the abutting block 707 and the positioning ring groove 702, so that the user can freely adjust the telescopic length of the lifting device. After the adjustment is completed, the control rod 701 is released. At this time, the abutting groove 706 on the bottom side of the staggered block 704 is staggered with the abutting block 707. At this time, the position of the abutting block 707 is fixed, so that the lifting device can maintain the current telescopic length and ensure the stability during use.

[0047] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 11 The lifting structure 5 includes a winding shaft 503. The top side of the grabbing head 201 is rotationally connected with the winding shaft 503. The middle part of the winding shaft 503 is fixedly connected with a traction rope 501. The other ends of the two traction ropes 501 are fixedly connected with a suspension block 502. The end part of the winding shaft 503 is provided with a ratchet groove 505. The inner side of the grabbing head 201 is slidably connected with a ratchet block 506. The ratchet block 506 is fixedly connected with the grabbing head 201 through a second spring 507. The end part of the ratchet block 506 is engaged with the winding shaft 503 through the ratchet groove 505. The top side of the grabbing head 201 is slidably connected with a pushing block 504. The bottom end of the pushing block 504 is abutted with the ratchet block 506.

[0048] In order to improve the strength of the lifting device when lifting the steel pipe, the winding shaft 503 is arranged on the two ends of the grabbing head 201. The ends of the two traction ropes 501 drawn by the winding shaft 503 are connected to the middle suspension block 502. The overall lifting device is pulled through the suspension block 502, so that the force transmission direction can be optimized, the strength of the lifting device is increased, and the user can press the pushing block 504 on the top side of the grabbing head 201 to adjust the length of the traction rope 501 according to the telescopic length of the lifting device. After the adjustment is completed, the pushing block 504 is released. Because the ratchet groove 505 is limited, the extension length of the front extension is fixed, so that the stable traction effect is achieved.

[0049] In use, first, the both ends of the mounting arm 1 are respectively provided with a grabbing head 201 for grabbing the stainless steel pipe, the both sides of the grabbing head 201 are respectively provided with an arc-shaped arc-shaped slide rod 202, and the inner side of the arc-shaped slide rod 202 is further provided with a grabbing rod 203, and the first spring 205 is connected between the grabbing rod 203 and the arc-shaped slide rod 202, so that the grabbing rod 203 can be automatically reset to the extended state. For the stainless steel pipe placed on the ground, if the vertical distance between the two ends of the grabbing rod 203 is less than the diameter of the steel pipe, the user can directly press down the device from the top side of the steel pipe, and when the grabbing rod 203 passes through the steel pipe, the grabbing rod 203 will automatically retract and then extend, realizing the grabbing of the steel pipe. At this time, the position of the fixed grabbing rod 203 can be fixed to complete the grabbing of the steel pipe, without the need for manual loading operation between the steel pipe and the lifting appliance, improving the operation efficiency. The side of the grabbing head 201 is provided with a telescopic sleeve rod 302, and the end of the telescopic sleeve rod 302 is engaged with the arc-shaped slide rod 202 arranged on the same side through the first tooth groove 303 and the second tooth groove 304, so that when the telescopic sleeve rod 302 rotates, the extension length of the arc-shaped slide rod 202 and the grabbing rod 203 will change, thereby facilitating the grabbing of pipes with different diameters. In order to facilitate adjustment, the telescopic sleeve rod 302 and the inner slide rod 305 arranged in the middle of the mounting arm 1 are slidingly connected, the user can rotate the adjusting worm 301 arranged on the side of the mounting arm 1, and the worm gear sleeve 306 can simultaneously drive the two telescopic sleeve rods 302 to rotate synchronously, thereby adjusting the distance between the grabbing rods 203. On the other hand, since the inner slide rod 305 and the telescopic sleeve rod 302 can slide, the user can adjust the distance between the two grabbing heads 201 according to the length of the pipe to be lifted, so that the pipe is more stable during transportation. Since the first spring 205 is connected between the grabbing rod 203 and the arc-shaped slide rod 202, if the pipe is too heavy after being grabbed by the grabbing rod 203, it will be dropped. In order to facilitate the grabbing and lifting of the pipe by the grabbing rod 203, the both sides of the grabbing rod 203 are provided with positioning blocks 605, and the positioning blocks 605 are engaged with the arc-shaped slide rod 202 through the positioning grooves 607, so that the grabbing rod 203 cannot be retracted at this time. If the grabbing rod 203 has completed the grabbing of the pipe at this time, the lifting appliance as a whole can be lifted, and the grabbing rod 203 can always remain in a fixed state to avoid the pipe from being dropped. When the pipe needs to be grabbed, the arc block 601 inside the grabbing head 201 needs to be slid, so that the arc groove 603 inside 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 blocks 605 are separated from the positioning grooves 607, that is, the fixed state of the grabbing rod 203 is released. At this time, the pipe on the ground can be grabbed by the grabbing 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 is arc-shaped,The sliding position of the arc-shaped sliding rod 202 does not affect the release effect of the grabbing rod 203. After completing the grabbing, the arc block 601 is released and reset, and the grabbing rod 203 can be fixed again, facilitating the transportation of the pipe. In order to facilitate the control of the fixed state of the grabbing rod 203, the arc block 601 slides on one side of the telescopic rotating rod 403, and the telescopic rotating rod 403 is rotationally connected with the grabbing head 201 on the same side. When it is needed to push the arc block 601 to release the grabbing rod 203, the user can turn the release rod 401 inside the middle limiting groove 405 of the mounting arm 1 to the other side. At this time, the transmission effect of the transmission sleeve 402 can drive the telescopic rotating rods 403 on both sides to rotate at the same time. At this time, the slide column 404 provided at the end of the telescopic rotating rod 403 will slide in the torsion groove 406 provided on the same side of the arc block 601. The structure of the torsion groove 406 will drive the arc block 601 to slide to one side, and then the fixed structure 6 will simultaneously release the fixing effect of the grabbing rod 203 on both sides. At this time, the pipe can be grabbed. After completing the grabbing, the release rod 401 is released, and the grabbing rod 203 can be fixed again. Through the arrangement of the inner slide 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 grabbing 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 appliance, a plurality of positioning ring grooves 702 are provided on the outer side of the telescopic sleeve rod 302 at equal intervals. The offset block 704 is provided on the top side of the abutting block 707. When the user presses the control rod 701 to make the offset block 704 slide inward, the abutting groove 706 on the bottom side of the offset block 704 provides space for the sliding of the abutting block 707. The abutting block 707 will play a positioning effect through the abutting action between the abutting block 707 and the positioning ring groove 702, so that the user can freely adjust the overall telescopic length of the lifting appliance. After completing the adjustment, the control rod 701 is released. At this time, the abutting groove 706 on the bottom side of the offset block 704 is offset from the abutting block 707. At this time, the position of the abutting block 707 is fixed, so that the lifting appliance can maintain the current telescopic length and ensure the stability during use. In order to improve the strength of the lifting appliance when lifting the steel pipe, the two grabbing heads 201 are provided with winding shafts 503. The traction ropes 501 connected to the winding shafts 503 are connected to the middle suspension block 502. The overall lifting appliance is pulled through the suspension block 502, which can optimize the force transmission direction and increase the strength of the lifting appliance. At the same time, according to the telescopic length of the lifting appliance, the user can press the pushing block 504 on the top side of the grabbing head 201 to make the ratchet block 506 disengage from the ratchet groove 505 on the winding shaft 503, and adjust the length of the traction rope 501. After completing the adjustment, the pushing block 504 is released. Due to the limitation of the ratchet groove 505, the length of the extended extension is fixed, thereby playing a stable traction effect.
