Description

Technical Field

[0001] This application relates to the field of lifting beams, and more specifically, to a lifting beam with a telescopic structure. Background Technology

[0002] A telescopic lifting beam is a type of lifting equipment that achieves length adjustment through a mechanical device. Its core design lies in expanding the working range, improving lifting stability, and adapting to complex working conditions through the telescopic sub-beam structure.

[0003] In the prior art, the lifting beam with telescopic structure consists of a main load-bearing beam, a telescopic secondary beam, a drive device, and a control system. The control system controls the drive device to work, thereby adjusting the extension length of the telescopic secondary beam to adapt to different working environments.

[0004] However, the existing telescopic lifting beams still have the following shortcomings in use: When the existing telescopic lifting beams are used to lift hollow pipes, the secondary beams can extend and retract, so the clamps can be inserted into the inside of the pipes, thereby improving the stability of the pipe lifting. However, because the inner diameter of the pipes is different, the clamps need to be replaced when the lifting beams lift pipes with different inner diameters. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a lifting beam with a telescopic structure, which aims to improve the problem that the clamps need to be replaced when lifting pipes with different inner wall diameters.

[0006] This application provides a lifting beam with a telescopic structure, including a main lifting beam. Both ends of the main lifting beam are slidably connected to auxiliary lifting beams. A driving device for moving the auxiliary lifting beams is provided on one side of the main lifting beam. An installation component is connected to the lower part of the auxiliary lifting beams. An adjustment mechanism for fixing pipes with different inner wall diameters is provided on one side of the installation component. A replacement mechanism for replacing clamps is provided on one side of the installation component.

[0007] The adjustment mechanism includes a vertical rod, which is disposed on one side of the mounting component. A first circular plate is connected to the top of the vertical rod, and a connector is connected to the top of the first circular plate. A second circular plate is rotatably connected to the other end of the connector.

[0008] In one specific implementation, a mounting bracket is connected to the top of the first circular plate, and a motor is connected to the other end of the mounting bracket. The output shaft of the motor is connected to the top of the second circular plate.

[0009] In the above implementation process, by setting up the motor, the output shaft of the motor can be controlled to rotate, thereby driving the second circular plate to rotate, and by setting up the mounting bracket, the motor body itself will not rotate.

[0010] In one specific implementation, the top of the first circular plate is connected to multiple sets of moving tracks, the inside of which is slidably connected to a moving component, and the outer surface of which is connected to a sliding component.

[0011] In the above implementation process, by setting the moving track, the moving part can slide inside the moving track, and the moving track provides the moving part with the direction of movement.

[0012] In one specific implementation, a sliding groove is provided through the top of the second circular plate, and a sliding member is slidably connected inside the sliding groove, with a limiting member connected to the other end of the sliding member.

[0013] In the above implementation process, by setting the sliding groove, when the second circular plate rotates, the sliding member can be driven to slide inside the sliding groove. Since the sliding member is connected to the moving member, the sliding member drives the moving member to move.

[0014] In one specific implementation, a crossbar is connected to the outer surface of the moving part, and the other end of the crossbar passes through the moving track and is connected to a fixing member.

[0015] In the above implementation process, by setting the crossbar, the crossbar can be moved when the moving part moves, thereby moving the fixing part, so that multiple sets of fixing parts are tightly attached to the inner wall of the pipe, fixing the pipe. Since the fixing parts can move, it is possible to fix pipes with different diameters on the inner wall.

[0016] In one specific implementation, the replacement mechanism includes a vertical plate connected to the bottom of a vertical rod. A first locking member is connected to one side of the vertical plate, and a second locking member is connected to the bottom of the vertical plate. Positioning holes are provided on one side of both the first and second locking members.

[0017] In the above implementation process, by setting the first and second clips, when clamping air materials and solid materials, it is possible to choose to insert the first clip into the interior of the mounting component or the second clip into the interior of the mounting component.

[0018] In one specific implementation, a slot is provided on one side of the mounting component, and both the first and second clips can be movably inserted into the interior of the slot.

[0019] In the above implementation process, by setting the card slot, the first card or the second card can be inserted into the inside of the card slot. By fixing the first card or the second card inside the card slot, the vertical plate is fixed to one side of the mounting component.

[0020] In one specific implementation, a housing is connected to one side of the mounting component, a movable plate is slidably connected inside the housing, a positioning component is connected to one side of the movable plate, and one end of the positioning component passes through the mounting component and can be movably inserted into the interior of two sets of positioning holes.

[0021] In the above implementation process, by setting the movable plate, when the movable plate is moved by an external force, it can drive the positioning component to move, causing the positioning component to disengage from the positioning hole, thereby releasing the positioning component from limiting the first or second card, and the first or second card can then disengage from the card slot.

[0022] In one specific implementation, a pull rod is connected to the other side of the movable plate, the other end of the pull rod passes through the housing and is connected to a pull plate, and a spring is sleeved on the outer surface of the pull rod.

[0023] In the above implementation process, by setting up the pull plate, the pull rod can be moved by pulling the pull plate, causing the spring to contract, which can make the positioning part disengage from the positioning hole. After the moving plate is no longer subject to external force, the spring will release elastic potential energy and drive the positioning part to reset.

[0024] In one specific implementation, a clamping plate is connected to the other side of the vertical plate.

[0025] In the above implementation process, by setting up the clamps, the materials that need to be hoisted can be placed on top of the clamps, which facilitates the hoisting of solid materials such as solid boards.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By adjusting the mechanism and replacing the mechanism, the second circular plate can be rotated by controlling the motor, which in turn moves the fixing parts, so that multiple sets of fixing parts are tightly attached to the inner wall of the pipe, thus fixing the pipe. Since the fixing parts can move, it can fix pipes with different inner diameters. When hoisting solid plates, the clamp can be changed to a clamp plate by replacing the mechanism, which facilitates the hoisting of solid plates. This solves the problem that the clamp needs to be replaced when the lifting beam is hoisting pipes with different inner diameters. Attached Figure Description

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a lifting beam with a telescopic structure, including a main lifting beam 1.

[0039] Please see Figure 1 and Figure 2 Both ends of the main lifting beam 1 are slidably connected to the auxiliary lifting beam 4. A drive device 6 for moving the auxiliary lifting beam 4 is provided on one side of the main lifting beam 1. An installation part 5 is connected to the bottom of the auxiliary lifting beam 4. An adjustment mechanism 2 for fixing pipes with different inner wall diameters is provided on one side of the installation part 5. A replacement mechanism 3 for replacing the clamp is provided on one side of the installation part 5.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The adjusting mechanism 2 includes a vertical rod 201, which is disposed on one side of the mounting component 5. A first circular plate 202 is connected to the top of the vertical rod 201, and a connector 207 is connected to the top of the first circular plate 202. A second circular plate 203 is rotatably connected to the other end of the connector 207.

[0041] In a specific configuration, a mounting bracket 204 is connected to the top of the first circular plate 202, and a motor 205 is connected to the other end of the mounting bracket 204. The output shaft of the motor 205 is connected to the top of the second circular plate 203. By configuring the motor 205, the second circular plate 203 can be rotated by controlling the output shaft of the motor 205. However, by configuring the mounting bracket 204, the motor 205 itself will not rotate.

[0042] In a specific configuration, the top of the first circular plate 202 is connected to multiple sets of moving rails 206. A moving part 2012 is slidably connected inside the moving rail 206, and a sliding part 2011 is connected to the outer surface of the moving part 2012. The moving rails 206 enable the moving part 2012 to slide inside the moving rails 206, and the moving rails 206 provide a direction for the moving part 2012 to move.

[0043] In a specific configuration, a sliding groove 2013 is provided through the top of the second circular plate 203. A sliding member 2011 is slidably connected inside the sliding groove 2013. The other end of the sliding member 2011 is connected to a limiting member 209. With the sliding groove 2013, when the second circular plate 203 rotates, the sliding member 2011 can be driven to slide inside the sliding groove 2013. Since the sliding member 2011 is connected to a moving member 2012, the sliding member 2011 drives the moving member 2012 to move.

[0044] In a specific configuration, a crossbar 208 is connected to the outer surface of the movable component 2012. The other end of the crossbar 208 passes through the movable track 206 and is connected to a fixing component 2010. The crossbar 208 can be moved when the movable component 2012 moves, thereby moving the fixing component 2010. This allows multiple sets of fixing components 2010 to be tightly attached to the inner wall of the pipe, thus fixing the pipe. Since the fixing component 2010 can move, it can fix pipes with different diameters on the inner wall.

[0045] In a specific configuration, the replacement mechanism 3 includes a vertical plate 301 connected to the bottom of the vertical rod 201. A first clamping member 302 is connected to one side of the vertical plate 301, and a second clamping member 3011 is connected to the bottom of the vertical plate 301. Positioning holes 303 are provided on one side of both the first clamping member 302 and the second clamping member 3011. By setting the first clamping member 302 and the second clamping member 3011, when clamping air materials and solid materials, the first clamping member 302 can be inserted into the interior of the mounting member 5, or the second clamping member 3011 can be inserted into the interior of the mounting member 5.

[0046] In a specific configuration, a slot 304 is provided on one side of the mounting component 5. The first card 302 and the second card 3011 can be movably inserted into the interior of the slot 304. By setting the slot 304, the first card 302 or the second card 3011 can be inserted into the interior of the slot 304. By fixing the first card 302 or the second card 3011 inside the slot 304, the vertical plate 301 is fixed to one side of the mounting component 5.

[0047] In a specific configuration, a housing 305 is connected to one side of the mounting component 5. A movable plate 307 is slidably connected inside the housing 305. A positioning component 306 is connected to one side of the movable plate 307. One end of the positioning component 306 passes through the mounting component 5 and can be movably inserted into the interior of two sets of positioning holes 303. By setting the movable plate 307, when the movable plate 307 is moved by an external force, it can drive the positioning component 306 to move, causing the positioning component 306 to disengage from the positioning hole 303. This releases the positioning component 306 from limiting the first locking component 302 or the second locking component 3011, allowing the first locking component 302 or the second locking component 3011 to disengage from the slot 304.

[0048] In a specific configuration, a pull rod 309 is connected to the other side of the movable plate 307. The other end of the pull rod 309 passes through the housing 305 and is connected to a pull plate 3010. A spring 308 is sleeved on the outer surface of the pull rod 309. By setting the pull plate 3010, the pull rod 309 can be moved by pulling the pull plate 3010, causing the spring 308 to contract. This allows the positioning member 306 to disengage from the positioning hole 303. After the movable plate 307 is no longer subjected to external force, the spring 308 will release its elastic potential energy, causing the positioning member 306 to reset.

[0049] In a specific configuration, a clamping plate 7 is connected to the other side of the vertical plate 301. The clamping plate 7 allows the material to be hoisted to be placed on top of the clamping plate 7, facilitating the hoisting of solid materials such as solid boards.

[0050] The working principle of this telescopic lifting beam is as follows: When using the telescopic lifting beam, the motor 205 drives the second circular plate 203 to rotate, causing the sliding member 2011 to slide inside the sliding groove 2013. Since the sliding member 2011 is connected to the moving member 2012, the moving member 2012 slides inside the moving track 206. The moving track 206 provides the moving direction for the moving member 2012. When the moving member 2012 moves, it drives the crossbar 208 to move, which in turn drives the fixing members 2010 to move, so that multiple sets of fixing members 2010 are tightly attached to the inner wall of the pipe, fixing the pipe. Because the fixing members 2010 can move, pipes of different diameters on the inner wall can be fixed. When lifting solid plates, it is possible to... By pulling the pull plate 3010, the pull rod 309 moves, causing the spring 308 to contract. This allows the positioning member 306 to disengage from the positioning hole 303, releasing the positioning member 306 from limiting the second clamping member 3011. The second clamping member 3011 can then disengage from the slot 304. Then, the first clamping member 302 is inserted into the slot 304. Without pulling the pull plate 3010 again, after the moving plate 307 is no longer subjected to external force, the spring 308 will release its elastic potential energy, causing the positioning member 306 to reset. Inserting the positioning member 306 into the positioning hole 303 of the first slot 304 allows the clamp to be changed to a clamping plate 7, which facilitates the lifting of solid plates. This solves the problem of having to change the clamp when lifting pipes with different inner walls and different diameters.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
