[0028] Please see Figures 1 to 6 This invention provides a pipe gripping and transporting device. This device can adjust the distance between two gripping units based on the different distances between two gripping holes on the pipe, ensuring that the two gripping units can cooperate with the two gripping holes to grip the pipe, thus facilitating the transport of pipes of different lengths.

[0029] In this specific embodiment, a pipe gripping and transferring device includes a transfer mechanism 1 and a gripping mechanism 2. The transfer mechanism 1 includes a guide rail 11, at least one movable member 12 movably connected to the guide rail 11, a first telescopic member 13 connected to the movable member 12, and a mounting frame 14 connected to the movable end of the first telescopic member 13. The movable member 12 can move along the length direction of the guide rail 11, and the first telescopic member 13 can be used to drive the mounting frame 14 to rise and fall. The two gripping mechanisms 2 are respectively disposed on opposite sides of the mounting frame 14. Each gripping mechanism 2 includes an adjustment unit 21 disposed on one side of the mounting frame 14 and a gripping unit 22 connected to the adjustment unit 21. The two adjustment units 21 can drive the two gripping units 22 to move closer or further away, so as to adjust the two gripping units 22 to correspond one-to-one with the two gripping holes on the pipe, so that the two gripping units 22 can cooperate with the two gripping holes of the pipe to fix and grip the pipe.

[0030] In actual use, depending on the distance between the two gripping holes on the pipe, the two adjustment units 21 can drive the two gripping units 22 to move closer or further apart, so that the two gripping units 22 correspond one-to-one with the two gripping holes on the pipe. The first telescopic member 13 drives the mounting frame 14 to descend, so that the two gripping units 22 can cooperate with the two gripping holes on the pipe to fix and grip the pipe. Then, the first telescopic member 13 drives the mounting frame 14 to rise. At the same time, the moving member 12 moves along the guide rail 11 to transfer the pipe.

[0031] In this specific embodiment, the mounting frame 14 is generally H-shaped. The mounting frame 14 includes a top plate 141, a connecting shaft 142, and a bottom plate 143. The top plate 141 is fixedly connected to the output end of the first telescopic member 13. One end of the connecting shaft 142 is rotatably connected to the top plate 141, and the other end of the connecting shaft 142 is fixedly connected to the bottom plate 143. The two adjustment units 21 are respectively disposed on opposite sides of the bottom plate 143. The transfer mechanism 1 also includes a driving member 15, which is disposed on the top plate 141 and connected to the connecting shaft 142. The driving member 15 is used to drive the connecting shaft 142 to rotate around its own axis.

[0032] It should be noted that the driving component 15 is not limited to a specific structure, as long as it can drive the connecting shaft 142 to rotate around its own axis. By driving the connecting shaft 142 to rotate around its own axis through the driving component 15, the two gripping units 22 are driven to rotate, ensuring that the two gripping units 22 can cooperate with the two gripping holes on the pipe.

[0033] In this specific embodiment, the guide rail 11 is generally H-shaped, and the guide rail 11 includes a first connecting plate 111, a second connecting plate 112, and a partition 113 connected between the first connecting plate 111 and the second connecting plate 112; the moving part 12 includes a support plate 121 and two drive motors 122, the support plate 121 is slidably connected to the lower surface of the second connecting plate 112, the two drive motors 122 are fixed on opposite sides of the support plate 121, the upper surface of the second connecting plate 112 is provided with racks 123 along the length direction on opposite sides of the partition 113, and the output shafts of the two drive motors 122 are respectively provided with gears 124 that mesh with the two racks 123.

[0034] It should be noted that by driving the two gears 124 to rotate through the two drive motors 122, the support plate 121 and the second connecting plate 112 can be driven to slide relative to each other. Specifically, the second connecting plate 112 is provided with a slide rail along its length, and the support plate 121 is provided with a slide groove that cooperates with the slide rail.

[0035] In this specific embodiment, the adjustment unit 21 includes an L-shaped mounting plate 211 slidably connected to the lower surface of the base plate 143, and a second telescopic member 212 fixedly mounted on the upper surface of the base plate 143. The movable end of the second telescopic member 212 is fixedly connected to the L-shaped mounting plate 211, and the second telescopic member 212 is used to drive the L-shaped mounting plate 211 to slide relative to the base plate 143. The gripping unit 22 is fixedly connected to the L-shaped mounting plate 211.

[0036] Based on the above scheme, the gripping mechanism 2 also includes a positioning unit 23, which includes a vertical plate 231 and a third telescopic member 232 fixed on the vertical plate 231. The movable end of the third telescopic member 232 is fixedly connected to the gripping unit 22.

[0037] Specifically, there are some irregularly shaped pipes, and the two gripping holes on the irregularly shaped pipes are in different planes, that is, there is a certain height difference between the two gripping holes. The position of the gripping unit 22 is adjusted by the third telescopic member 232 to ensure that when the first telescopic member 13 drives the mounting frame 14 to rise and fall, both gripping units 22 can cooperate with the two gripping holes to grip the irregularly shaped pipes.

[0038] In this specific embodiment, the gripping unit 22 includes a connecting seat 221, a fourth telescopic member 222, an L-shaped connecting block 223, a hook block 224, and a guide head 225. The connecting seat 221 is fixedly connected to the output end of the third telescopic member 232. The fourth telescopic member 222 is fixedly mounted on one side of the connecting seat 221. The middle part of the L-shaped connecting block 223 is hinged to the connecting seat 221, and the movable end of the fourth telescopic member 222 is hinged to one end of the L-shaped connecting block 223. The other end of the L-shaped connecting block 223 is hinged to the hook block 224. The guide head 225 is fixedly connected to the connecting seat 221. The hook block 224 passes through the guide head 225. When the guide head 225 passes through a gripping hole of the pipe, the fourth telescopic member 222 can drive the hook block 224 to extend to the outside of the guide head 225. A clamping space is formed between the hook block 224 and the connecting seat 221 for fixing the edge of the gripping hole of the pipe.

[0039] It should be noted that when the guide head 225 of the gripping unit 22 extends into the gripping hole of the pipe, the L-shaped connecting block 223 is driven to rotate by the fourth telescopic member 222, so that the hook block 224 can extend out to the outside of the guide head 225, and the hook block 224 can fix the edge of the gripping hole of the pipe in the clamping space.

[0040] To improve the stability of the gripping unit 22 installation, specifically, slide rails 233 are provided on both sides of the vertical plate 231 and the opposite sides of the third telescopic member 232, and sliders 234 that cooperate with the two slide rails 233 are fixed on the connecting seat 221.

[0041] To facilitate the installation of the guide rail 11 onto the roof beams of the production workshop, specifically, the first connecting plate 111 is provided with multiple fixing plates 114 spaced apart along its length. The fixing plates 114 have connecting holes, and are fixedly connected to the roof beams by screws engaging with these holes.

[0042] In this specific embodiment, the driving component 15 includes a reduction motor 151, a first bevel gear 152, and a second bevel gear 153 fixedly connected to the top plate 141.

According to the distance between two gripping holes opened on the pipe, the two adjustment units can drive the two gripping units to move closer or further away, so as to adjust the two gripping units to correspond one-to-one with the two gripping holes on the pipe, so that the two gripping units can cooperate with the two gripping holes of the pipe to fix and grip the pipe. Without the need to change different gripping and transfer devices, pipes of different lengths can be effectively gripped and transported by moving the moving part along the length direction of the guide rail. The structure is simple and easy to use.
