[0002] The material turning hook shaft is a component of mechanical equipment used for material handling and processing. It is usually used to lift and turn materials for loading and unloading or transfer. The material turning hook shaft is widely used in various material handling and processing equipment, such as cranes, forklifts, loaders, etc. It can be used to lift and turn various materials, such as wood, metal, plastic, paper, etc.

[0006] To achieve the above object, the present invention provides the following technical solutions: The cam is provided with a plurality of sliding holes, and the two sliding holes are provided on the two hooks, and the sliding holes are provided with three sliding holes. The two sliding holes are provided with an adjusting component in the middle of the two sliding components. The adjusting component is installed in the hook shaft, and the two ends of the adjusting component pass through the two ends of the hook shaft. The fixing sleeve and the sliding component are respectively fixedly connected to the fixing frame, and the two sides of the inner wall of the fixing frame are respectively installed with a deflection assembly. The deflection assembly passes through one end of the fixing frame and is provided with a limit seat. The limit seat is fixed to one side of the fixing frame. The fixing frame is provided with a mounting assembly, and the ends of the two deflection assemblies close to each other are fixed to the two sides of the mounting assembly. The mounting assembly is provided with an insertion shaft, and the end of the insertion shaft away from the mounting assembly is fixedly connected with the material turning hook.
[0007] As a further solution of the present invention, gear parts are respectively installed on both sides of the outer wall of the hook shaft, shaft sleeves are respectively clamped at both ends of the hook shaft, and the adjustment component is connected to the two ends of the hook shaft through the shaft sleeves.
[0008] As a further solution of the present invention, the sliding assembly includes a sliding sleeve, which is arranged outside the hook shaft, one side of the sliding sleeve is fixed to the fixed frame, three sliding blocks are fixed to the inner wall of the sliding sleeve, the sliding blocks are slidably connected in the sliding hole, and a nut is fixedly connected to one side of the three sliding blocks close to each other, and the nut is located in the hook shaft and is threadedly connected to the outside of the adjustment assembly.
[0009] As a further solution of the present invention, the adjusting assembly includes a screw rod, the threads on both sides of the outer wall of the screw rod are in opposite directions, and a bearing seat is provided in the middle of the screw rod, and the bearing seat is clamped in the middle of the inner wall of the hook shaft. The sliding assembly is threadedly connected to the outside of the screw rod, and both ends of the screw rod pass through the hook shaft and are fixed with a rotating handle.
[0010] As a further solution of the present invention, the deflection assembly includes a rotating shaft, a bearing sleeve is outer-connected to the rotating shaft, the bearing sleeve is clamped on one side of the fixed frame, one end of the rotating shaft is fixed to the mounting assembly, and the other end of the rotating shaft is provided with a sliding groove, and the top end of the limit seat is slidably connected in the sliding groove.
[0011] As a further solution of the present invention, a retaining ring is fixed outside the rotating shaft, a coil spring is fixed between the retaining ring and the inner wall of the fixing frame, and the coil spring is sleeved outside the rotating shaft.
[0012] As a further solution of the present invention, the mounting assembly includes a socket, both sides of which are respectively fixed to the ends of the two deflection assemblies that are close to each other, a slot is provided on one side of the socket, the plug shaft is clamped in the slot, a bolt member is installed through the socket, and the bolt member is arranged through the plug shaft.
[0013] A method for using an adjustable material turning hook shaft assembly that is easy to assemble, the method comprising the following steps: When adjusting the spacing between multiple material turning hooks, the screw rod is driven to rotate by rotating the handle. Since the threads on the two sides outside the screw rod are in opposite directions, the two nuts outside the screw rod can move relatively, and the nut drives the sliding sleeve to move through the sliding block, and the sliding block is limited by the sliding hole, thereby improving the stability of the horizontal movement of the sliding sleeve driven by the sliding block. The sliding sleeve drives the turning hook to move through the fixed frame, the deflection assembly and the mounting assembly. Since the turning hooks on the two sides outside the hook shaft move relatively, the spacing between the three turning hooks can be changed, which is suitable for turning short pipes. When the spacing between the three turning hooks is expanded, the rotating handle is rotated in the opposite direction to make the rotating handle drive the screw rod to rotate. Similarly, the two sliding sleeves gradually move away from the fixed sleeve, so that the turning hooks on the two sides outside the hook shaft move away from each other, so that the turning hooks can stably turn the long pipe. By adjusting the distance between two adjacent turning hooks, the purpose of turning pipes of different lengths can be met. When turning over the pipe, the hook shaft assembly is installed at the specified position, and is meshed and connected with the gear part outside the hook shaft through the external driving mechanism. The external driving mechanism works and drives the gear part to rotate, and the gear part drives the hook shaft to rotate, and the hook shaft drives multiple turning hooks to rotate and approach the pipe below. When the bottom of the turning hook contacts the top of the pipe, the hook shaft continues to rotate upward. During the process of the hook shaft being compressed, it can drive the two deflection assemblies to rotate through the installation assembly, so that the top of the limit seat can slide in the sliding groove at the end of the rotating shaft until the turning hook rotates to the bottom of the pipe. The retaining ring is pulled to rotate by the force of the coil spring outside the rotating shaft, so that the retaining ring can return to its position through the rotating shaft and the installation assembly, so that the installation assembly drives the turning hook back to a horizontal angle. By driving the gear member to rotate in the opposite direction through the external driving component, the hook shaft drives the multiple material turning hooks to rotate. In the process of lifting the pipe by the material turning hook, the sliding groove at the end of the rotating shaft can slide on the top of the limit seat. When the limit seat is close to the inner wall of the sliding groove, the rotating shaft will not turn downward, which plays a role in supporting and limiting the rotating shaft and the material turning hook, preventing the material turning hook from continuing to turn downward and being difficult to lift the pipe. Therefore, multiple material turning hooks can hook the pipe and turn it over. After completing a single turning work, the material turning hook turns downward again to repeat the turning step. When replacing the tipping hook, loosen the bolt on the holder and pull out the bolt to release the locking state of the plug shaft. Pull the tipping hook to drive the plug shaft out of the slot in the holder to remove the tipping hook. When installing the tipping hook, hold the tipping hook to insert the plug shaft into the slot, then pass the bolt through the holder and the plug shaft. After tightening the bolt, the tipping hook can be locked, so that the tipping hook can be installed on the fixed frame.
[0014] Compared with the prior art, the present invention has the following beneficial effects: The invention drives the screw rod to rotate by rotating the turning handle, so that the two nuts outside the screw rod can move relatively, and the nut drives the sliding sleeve to move through the sliding block, and the sliding block is limited by the sliding hole, so as to improve the stability of the horizontal movement of the sliding sleeve driven by the sliding block, and the sliding sleeve drives the turning hook to move through the fixing frame, the deflection assembly and the mounting assembly. Since the turning hooks on both sides outside the hook shaft move relatively, the spacing between the three turning hooks can be changed, which is suitable for turning the short pipe. When the spacing between the three turning hooks is expanded, the turning handle is rotated in the opposite direction to make the turning handle drive the screw rod to rotate. Similarly, the turning hooks on both sides outside the hook shaft are separated from each other, so that the turning hooks can stably turn the long pipe. By adjusting the distance between the two adjacent turning hooks, the purpose of turning the pipes of different lengths can be met. The traditional turning hook shaft assembly with an integrated design is abandoned, which is conducive to efficient and stable turning of the pipe.
[0015] 2. The present invention drives multiple material turning hooks to rotate and approach the pipe below through the hook shaft. When the bottom of the material turning hook contacts the top of the pipe, the hook shaft can drive the two deflection assemblies to rotate through the installation assembly during the pressure process until the material turning hook rotates to the bottom of the pipe, and the retaining ring is pulled to rotate by the action of the outer coil spring of the rotating shaft, so that the retaining ring can return to its original position through the rotating shaft and the installation assembly, so that the installation assembly drives the material turning hook back to a horizontal angle, and the gear part rotates in the opposite direction, and the hook shaft drives multiple material turning hooks to rotate. In the process of lifting the pipe by the turning hook, the sliding groove at the end of the rotating shaft can slide on the top of the limit seat. When the limit seat is close to the inner wall of the sliding groove, the rotating shaft will not flip downward, which plays a role of supporting and limiting the rotating shaft and the turning hook, preventing the turning hook from continuing to flip downward and making it difficult to lift the pipe. There is no need to increase the stroke of the turning hook to perform the turning work, thereby improving the turning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A method for using an adjustable material turning hook shaft assembly that is easy to assemble, the method comprising the following steps: When adjusting the spacing between the multiple material turning hooks 12, the screw rod 501 is driven to rotate by rotating the handle 503. Since the threads on both sides of the screw rod 501 are in opposite directions, the two nuts 303 outside the screw rod 501 can move relative to each other. The nut 303 drives the sliding sleeve 301 to move through the sliding block 302. The sliding block 302 is limited by the sliding hole 4 to improve the stability of the horizontal movement of the sliding sleeve 301 driven by the sliding block 302. The sliding sleeve 301 drives the material turning hook 12 to move through the fixing frame 7, the deflection assembly 8 and the mounting assembly 10. The material turning hooks 12 on the outer sides move relative to each other, which can change the spacing between the three material turning hooks 12, and is suitable for turning short pipes. When the spacing between the three material turning hooks 12 is expanded, the handle 503 is rotated in the opposite direction to drive the screw rod 501 to rotate. Similarly, the two sliding sleeves 301 gradually move away from the fixed sleeve 2, so that the material turning hooks 12 on the outer sides of the hook shaft 1 move away from each other, so that the material turning hooks 12 can stably turn long pipes. By adjusting the distance between two adjacent material turning hooks 12, the purpose of turning pipes of different lengths can be met. When turning over the pipe, the hook shaft 1 assembly is installed at the specified position, and is meshed and connected with the gear member 6 outside the hook shaft 1 through an external driving mechanism. The external driving mechanism works and drives the gear member 6 to rotate, and the gear member 6 drives the hook shaft 1 to rotate, and the hook shaft 1 drives multiple turning hooks 12 to rotate and approach the pipe below. When the bottom of the turning hook 12 contacts the top of the pipe, the hook shaft 1 continues to rotate upward. During the pressure of the hook shaft 1, the two deflection assemblies 8 can be driven to rotate through the installation assembly 10, so that the top of the limit seat 9 can slide in the sliding groove 805 at the end of the rotating shaft 801, until the turning hook 12 rotates to the bottom of the pipe, and the retaining ring 803 is pulled to rotate by the force of the outer coil spring 804 of the rotating shaft 801, so that the retaining ring 803 can return to its position through the rotating shaft 801 and the installation assembly 10, so that the installation assembly 10 drives the turning hook 12 back to a horizontal angle; By driving the gear member 6 to rotate in the opposite direction through the external driving component, the hook shaft 1 drives the multiple material turning hooks 12 to rotate. In the process of lifting the pipe by the material turning hook 12, the sliding groove 805 at the end of the rotating shaft 801 can slide on the top of the limiting seat 9. When the limiting seat 9 is close to the inner wall of the sliding groove 805, the rotating shaft 801 will not turn over downward, which plays a role in supporting and limiting the rotating shaft 801 and the material turning hook 12, preventing the material turning hook 12 from continuing to turn downward and being difficult to lift the pipe, thereby enabling the multiple material turning hooks 12 to hook up the pipe and turn it over. After completing a single turning work, the material turning hook 12 turns downward again to repeat the turning step. When replacing the material turning hook 12, the bolt 103 on the holder 101 is loosened and the locking state of the plug shaft 11 can be released after the bolt 103 is pulled out. The material turning hook 12 can be removed by pulling the material turning hook 12 to drive the plug shaft 11 out of the slot 102 in the holder 101. When installing the material turning hook 12, hold the material turning hook 12 to insert the plug shaft 11 into the slot 102, and then pass the bolt 103 through the holder 101 and the plug shaft 11. After tightening the bolt 103, the material turning hook 12 can be locked, so that the material turning hook 12 can be installed on the fixing frame 7.

During the process of the hook shaft (1) being pressed, the hook shaft (1) can pass through the hook shaft (1) to rotate. The mounting assembly (10) drives the two deflection assemblies (8) to rotate, so that the top of the limit seat (9) can slide in the sliding groove (805) at the end of the rotating shaft (801) until the material turning hook (12) rotates to the bottom of the pipe, and the retaining ring (803) is pulled to rotate by the action of the outer coil spring (804) of the rotating shaft (801), so that the retaining ring (803) can return to its original position through the rotating shaft (801) and the mounting assembly (10), so that the mounting assembly (10) drives the material turning hook (12) to return to a horizontal angle; By driving the gear member (6) to rotate in the opposite direction through the external driving component, the hook shaft (1) drives the multiple material turning hooks (12) to rotate. In the process of the material turning hook (12) lifting the pipe, the sliding groove (805) at the end of the rotating shaft (801) can slide on the top of the limiting seat (9). When the limiting seat (9) is close to the inner wall of the sliding groove (805), the rotating shaft (801) will not turn downward, which plays a role in supporting and limiting the rotating shaft (801) and the material turning hook (12), preventing the material turning hook (12) from continuing to turn downward and being difficult to lift the pipe, thereby enabling the multiple material turning hooks (12) to hook the pipe and turn it over. After completing a single turning operation, the material turning hook (12) turns downward again to repeat the turning step. When replacing the material turning hook (12), the bolt member (103) on the holder (101) is loosened and the locking state of the insertion shaft (11) can be released after the bolt member (103) is pulled out. The material turning hook (12) can be removed by pulling the material turning hook (12) to drive the insertion shaft (11) to disengage from the slot (102) in the holder (101). When installing the material turning hook (12), the material turning hook (12) is held to insert the insertion shaft (11) into the slot (102). Then, the bolt member (103) is passed through the holder (101) and the insertion shaft (11). After the bolt member (103) is locked, the material turning hook (12) can be locked, so that the material turning hook (12) can be installed on the fixing frame (7).
