Description

Technical Field

[0001] This invention relates to the field of hoisting and transportation technology, and more specifically, to a hoisting and transportation device. Background Technology

[0002] In related technologies, the transportation and hoisting of pipelines, steel, and various small and medium-sized materials and equipment in industrial production, construction, and logistics largely rely on traditional manual operations and simple mechanical auxiliary tools. Workers typically need to manually transport pipelines, steel, and other materials to the installation location before hoisting them. During hoisting, the common practice is to install a lifting frame and then use hand-operated hoists, electric hoists, and other hoisting tools to complete the hoisting task.

[0003] Throughout the process, manual handling is relatively inefficient, especially when dealing with large or heavy materials. It requires multiple workers to work together, resulting in slow handling speed and easy fatigue, which significantly reduces work efficiency. During the hoisting and installation process using equipment such as hand chain hoists, there is a risk of material swinging, slipping, and falling. Installing the lifting frame and operating equipment such as hand chain hoists and electric hoists requires a lot of time for assembly and debugging, and requires certain professional knowledge and skills. Improper operation may cause safety accidents. At the same time, the manual pulling of materials for installation and alignment requires the cooperation of multiple people, resulting in low work efficiency. Summary of the Invention

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1 to 6 As shown, the hoisting and transportation device of this embodiment includes a frame 1, a drive plate 2, a connecting arm 3, and a clamping assembly 4. The length direction of the frame 1 is defined as the front-to-back direction, the height direction of the frame 1 is defined as the up-down direction, and the width direction of the frame 1 is defined as the left-to-right direction.

[0041] The frame 1 includes a base plate 11 for movement and a support frame 12 disposed on the base plate 11. Two stops 13 are provided on the base plate 11 at intervals along the front-back direction. A fixed cavity for accommodating steel or steel pipe is defined between the two stops 13. The drive plate 2 is disposed on the support frame 12 with adjustable position along the up-down direction.

[0042] Multiple connecting arms 3 are provided and pivotally connected in sequence. A first drive unit 5 is provided between two adjacent connecting arms 3 to drive the connecting arms 3 to rotate. The first drive unit 5 causes the two connected connecting arms 3 to rotate relative to each other in the vertical or horizontal direction. The connecting arm 3 located on the rear side is rotatably connected to the drive plate 2. The drive plate 2 is provided with a second drive unit 6 to drive the connected connecting arms 3 to rotate. The rotation axis of the connecting arm 3 located on the rear side extends in the horizontal direction relative to the drive plate 2. The second drive unit 6 drives the multiple connecting arms 3 and the clamping assembly 4 to rotate in the vertical direction. The connecting arm 3 located on the front side is rotatably connected to the clamping assembly 4. The connecting arm 3 located on the front side is provided with a third drive unit 7 for driving the clamping assembly 4 to rotate. The rotation axis of the connecting arm 3 located on the front side and the clamping assembly 4 is perpendicular to the rotation axis of the connecting arm 3 located on the rear side relative to the drive plate 2. The clamping assembly 4 is driven to rotate around the connecting arm 3 connected to it by the third drive unit 7, so as to adjust the working posture of the clamping assembly 4. Multiple connecting arms 3 are used to drive the clamping assembly 4 to move and adjust the clamping posture of the clamping assembly 4. The clamping assembly 4 is used to clamp steel or steel pipe.

[0043] When the hoisting and transporting device of this embodiment is in use, it moves to the area to be loaded via the base plate 11. The first drive unit 5 and the second drive unit 6 drive multiple connecting arms 3 to move towards or away from the drive plate 2 to move the clamping assembly 4 in space. The clamping assembly 4 is moved to the position of the steel pipe or steel to be transported. The clamping assembly 4 clamps the steel pipe and steel and moves to the fixed cavity formed between the stop bars 13 by the rotation of the connecting arms 3. It moves to the installation area via the base plate 11. The first drive unit 5 and the second drive unit 6 drive multiple connecting arms 3 to rotate to drive the clamping assembly 4 to move. The clamping assembly 4 clamps the steel pipe or steel on the base plate 11. The third drive unit 7 drives the clamping assembly 4 to rotate relative to the connecting arms 3 to adjust the posture of the clamping assembly 4 so that the steel pipe or steel is vertical, horizontal or inclined. At the same time, the first drive unit 5 and the second drive unit 6 drive multiple connecting arms 3 to rotate to adjust the position of the steel pipe or steel clamped by the clamping assembly 4 to carry out the hoisting operation of the steel pipe or steel.

[0044] The hoisting and transporting device of this invention provides support and limit for the transport of steel pipes and steel materials through the base plate 11, and realizes the mechanical handling of steel pipes and steel materials through the connecting arm 3 and the clamping assembly 4. It is easy to operate, saves a lot of manpower, and has high operating efficiency. At the same time, by setting the first drive unit 5, the second drive unit 6 and the third drive unit 7, the individual drive between the connecting arm 3 and the drive plate 2, between the connecting arms 3 and the connecting arm 3, and between the connecting arm 3 and the clamping assembly 4 is realized. This facilitates accurate adjustment of the position of the clamping assembly 4, and the third drive unit 7 realizes the adjustment of the posture of the clamping assembly 4. It can realize hoisting operations on steel pipes and steel materials in different installation states, realize the rapid installation of steel materials and steel pipes, and improve construction efficiency and construction safety.

[0045] Optionally, such as Figure 3 As shown, both the first drive unit 5 and the second drive unit 6 include a drive motor and a reducer fixedly mounted on the connecting arm 3. The reducer is located at the output end of the drive motor, and the output end of the reducer is fixedly connected to the corresponding adjacent connecting arm 3.

[0046] Optionally, such as Figure 3 As shown, the third drive unit 7 includes a servo motor, which is fixedly mounted at the end of the connecting arm 3. The output shaft of the servo motor extends along the direction of extension of the connecting arm 3 and is fixedly connected to the clamping assembly 4.

[0047] In some embodiments, the system further includes a connecting plate 14 and a fourth driving unit 8. The connecting plate 14 is rotatably mounted on the driving plate 2 and the axis of rotation of the connecting plate 14 extends in the front-rear direction. The fourth driving unit 8 is mounted on the driving plate 2 and is used to drive the connecting plate 14 to rotate. The connecting arm 3 located on the rear side is rotatably connected to the connecting plate 14, and the axis of rotation of the connecting arm 3 located on the rear side and the axis of rotation of the connecting plate 14 extend in the left-right direction.

[0048] Specifically, such as Figures 1 to 4 As shown, the connecting plate 14 is rotatably mounted on the drive plate 2 via bearings. The fourth drive unit 8 includes a servo motor fixedly mounted on the drive plate 2. The output shaft of the servo motor is fixedly connected to the connecting plate 14 to drive the connecting plate 14 to rotate. The second drive unit 6 is mounted on the connecting arm 3 to control the connecting arm 3 to rotate in the vertical direction, thereby adjusting the height of the clamping assembly 4. By setting the fourth drive assembly, the overall rotation of multiple connecting parts and the clamping assembly 4 in the vertical plane is further realized, which facilitates the adjustment of the working posture of the clamping assembly 4 and makes the operation convenient.

[0049] In some embodiments, at least three connecting arms 3 are provided, and the rotation axis between any two adjacent connecting arms 3 is defined as the adjustment axis. The extension direction of at least one adjustment axis is perpendicular to the extension direction of the rotation axis between the connecting arm 3 located on the rear side and the connecting plate 14.

[0050] Specifically, the device is equipped with a first arm, a second arm, and a third arm. The first arm is rotatably connected to the connecting plate 14, the first arm and the second arm are rotatably connected, the second arm and the third arm are rotatably connected, and the third arm is rotatably connected to the clamping assembly 4. The rotation axis between the first arm and the connecting plate 14 extends in the left-right direction, meaning that the first arm rotates relative to the connecting plate 14 in the up-down direction. The rotation axis between the first arm and the second arm extends in the up-down direction, meaning that the second arm rotates relative to the first arm in the left-right direction. This allows for adjustment of the position of the clamping assembly 4 in the left-right direction, facilitating the hoisting and installation of steel pipes and steel materials, and making operation convenient.

[0051] Optionally, a fourth arm is also provided. In this case, the fourth arm is rotatably connected to the third arm and rotatably connected to the clamping assembly 4. The rotation axis of the third arm and the second arm or the rotation axis of the fourth arm and the third arm extends in the vertical direction to further adjust the position of the clamping assembly 4 in the horizontal direction, which facilitates the positioning and alignment of the steel pipe and steel during hoisting and installation. The operation is convenient, safe and reliable.

[0052] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the controller 9 is located on the base plate 11 and on the rear side of the support frame 12. The controller 9 is electrically connected to the first drive unit 5, the second drive unit 6, the third drive unit 7 and the fourth drive unit 8 respectively to control the movement of the connecting plate 14 and the connecting arm 3 driving the clamping assembly 4.

[0053] Specifically, a support platform is provided on the base plate 11, and the controller 9 is set above the support platform and tilted to conform to the viewing and operation habits of personnel. A mobile power supply is provided in the support platform. The mobile power supply is used to provide energy for the controller 9 and the first drive unit 5, the second drive unit 6, the third drive unit 7 and the fourth drive unit 8. The controller 9 can control the rotation between the connecting plate 14 and the connecting arm 3, between two adjacent connecting arms 3 and between the connecting arm 3 and the clamping assembly 4, thereby realizing the movement of the clamping assembly 4. The operation is convenient and the work efficiency is improved.

[0054] In some embodiments, such as Figure 5 As shown, the clamping assembly 4 includes a fixing plate 41 and a clamping unit 42. The fixing plate 41 is rotatably connected to the connecting arm 3 located on the front side. The clamping unit 42 is located on the side of the fixing plate 41 away from the connecting arm 3. The clamping unit 42 includes a first clamping plate 421 and a second clamping plate 422 that are arranged opposite to each other and whose positions are adjustable. The first clamping plate 421 and the second clamping plate 422 are used to clamp steel or steel pipe.

[0055] Specifically, the fixed plate 41 is connected to the connecting arm 3 via the third drive unit 7 and rotates relative to the connecting part under the action of the third drive unit 7. The clamping unit 42 includes a split rodless cylinder 423, a first clamping plate 421 and a second clamping plate 422. The split rodless cylinder 423 is electrically connected to the controller 9. The split rodless cylinder 423 includes a cylinder and two drive blocks set on the cylinder. The first clamping plate 421 and the second clamping plate 422 are respectively fixedly connected to the two drive blocks. The controller 9 controls the two drive blocks to move closer or further away from each other to drive the first clamping plate 421 and the second clamping plate 422 to move closer or further away from each other, thereby realizing the clamping operation of the clamping component 4 on the object. The operation is convenient and safe.

[0056] In some embodiments, multiple clamping units 42 are arranged in parallel and used to clamp steel or steel pipes together. By setting multiple clamping units 42 in parallel, the contact area between the clamping assembly 4 and the steel and steel pipes can be increased, further improving the stability and reliability of the clamping assembly 4 when clamping the steel and steel pipes, avoiding slippage of the steel or steel rod from the clamping assembly 4, and improving construction safety. Pressure plates 424 are respectively provided on the sides of the first clamping plate 421 and the second clamping plate 422 that are close to each other. The sides of the pressure plates 424 that are close to each other are provided with concave fixing grooves. Through the fixing grooves on the pressure plates 424, it is convenient for the first clamping plate 421 and the second clamping plate 422 to clamp the steel or steel pipes, improving the reliability of the clamping operation.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two pairs of stop bars 13 along the left and right directions, and the bottom plate 11 is provided with a relief groove 111 extending in the front and back directions, and the relief groove 111 is located between the two pairs of stop bars 13 that are spaced apart in the left and right directions.

[0058] The paired stop bars 13 ensure the steel or steel pipe is fixed when placed on the base plate 11, preventing the steel or steel pipe from shaking and falling. The base plate 11 is provided with a relief groove 111. When the clamping assembly 4 clamps the steel or steel pipe on the base plate 11, part of the rod ends of the first clamping plate 421 and the second clamping plate 422 of the clamping assembly 4 extend into the relief groove 111, so that the clamping center of the clamping assembly 4 is aligned with the clamping center of the steel channel or steel pipe, thereby ensuring the reliability of the clamping assembly 4 when clamping the steel or steel pipe and preventing the steel or steel pipe from slipping.

[0059] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, a slider 15 is provided on the base plate 11 corresponding to the stop bar 13. The stop bar 13 is located on the slider 15, and the slider 15 is located on the base plate 11 with adjustable position in the front-back direction.

[0060] Specifically, the base plate 11 is provided with a sliding groove extending in the front-to-back direction corresponding to the slider 15. The cross-section of the sliding groove is T-shaped. The slider 15 is slidably disposed in the sliding groove. By moving the slider 15, the position of the stop bar 13 can be adjusted, thereby adjusting the size of the fixing cavity to ensure the fixed limit of the steel or steel pipe, and to prevent the steel or steel pipe from moving or shaking during transportation, which is safe and reliable.

[0061] Optionally, a first screw extending in the front-rear direction is provided on the base plate 11 corresponding to the stop bar 13. The first screw includes two threaded sections with opposite directions of rotation and the same length. The stop bars 13 arranged in pairs in the front-rear direction are respectively threaded onto the two threaded ends of the first screw. A first motor is provided at one end of the first screw. The first motor is electrically connected to the controller 9. The controller 9 controls the rotation of the first motor, thereby driving the first screw to rotate and drive the two stop bars 13 to move towards each other or away from each other, so as to facilitate the adjustment of the size of the fixing cavity to adapt to the fixing of steel and pipes of different sizes.

[0062] Optionally, such as Figure 6 As shown, the front and rear shells of slider 15 are made of magnetically conductive iron, while the upper and lower shells are made of non-magnetically conductive copper. A neodymium iron boron magnet is rotatably mounted inside slider 15. A knob 16 is located on the outside of slider 15, connected to and used to drive the neodymium iron boron magnet to rotate. The neodymium iron boron magnet has a north pole (N pole) and a south pole (S pole). Magnetic field lines originate from the N pole, pass through external space or magnetic materials, and return to the S pole, forming a closed magnetic field loop. Rotating the neodymium iron boron magnet, when the neodymium iron boron magnet is located at... In the horizontal state, the N and S poles are respectively facing the two magnetic conductors, and the magnetic lines of force form a closed loop inside the magnetic conductors. The magnetic lines of force do not pass through the external space, and the slider 15 does not show magnetism to the outside. The slider 15 can move easily. When the rotating magnet is in the vertical state, the N and S poles of the magnet are facing the upper and lower shells of the slider 15 respectively. The magnetic lines of force start from the N pole of the magnet, pass through the shell and the external metal surface, and return to the S pole of the magnet, forming an external closed magnetic circuit, thereby firmly adsorbing the slider 15 onto the base plate.

[0063] In some embodiments, such as Figure 6 As shown, the stop rod 13 is rotatably mounted on the base plate 11. Specifically, the stop rod 13 is rotatably mounted on the slider 15 via a rotating shaft, allowing it to rotate freely. The slider 15 has multiple first holes along the circumferential direction corresponding to the rotating shaft, and the stop rod 13 has multiple second holes corresponding to the rotating shaft. Limiting rods pass through the first and second holes. By selecting different first and second holes, the limiting rods can be fixed in both vertical and horizontal states, respectively; or, as... Figure 6As shown, a locking rod 17 is fixedly provided on the stop rod 13. One end of the locking rod 17 slides through the slider 15 and engages with the slider 15 to prevent rotation. The cross-section of the rod segment of the locking rod 17 that passes through the slider 15 is a positive polygonal shape. By selecting different insertion angles when the locking rod 17 passes through the slider 15, the angle between the stop rod 13 and the base frame can be adjusted so that the stop rod 13 has a vertical state and a horizontal state. In normal state, the stop rod 13 remains horizontal. When it is necessary to fix the steel, it can be adjusted to a vertical state. When loading and unloading, it can be restored to a horizontal position, which is convenient and quick.

[0064] In some embodiments, the length of the stop bar 13 is adjustable. Optionally, the stop bar 13 includes a threaded first tube, an intermediate rod, and a second tube. By adjusting the thread length of the intermediate rod in the first and second tubes, the length of the stop bar 13 can be adjusted to accommodate the fixing of steel and steel pipes of different sizes.

[0065] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the support frame 12 includes two parallel vertical rods and a horizontal rod connecting the two vertical rods. Two second screws 10 are rotatably provided on the horizontal rod. The ends of the two second screws 10 are rotatably connected to the base plate 11, and the two second screws 10 are threadedly engaged with the drive plate 2.

[0066] Specifically, two vertical rods are fixedly mounted on the base plate 11, and a horizontal rod is fixedly connected to the top of the two vertical rods. Two second screws 10 are vertically mounted and threadedly connected to the horizontal rod. The bottom end of the second screw 10 is rotatably connected to the base plate 11 through a bearing. A drive block is threadedly mounted on the two second screws 10. The top of the second screw 10 is connected to a second motor 101 through a coupling. The second motor 101 is fixedly connected to the horizontal rod and electrically connected to the controller 9. The controller 9 controls the rotation of the two second motors 101, thereby driving the two screws to rotate in the same direction, so that the drive plate 2 moves in the up and down direction under the action of the two second screws 10, which facilitates the adjustment of the position of the drive plate 2 and makes the operation convenient and reliable.

[0067] Optionally, the left and right ends of the drive block are slidably engaged with the two vertical rods respectively.

[0068] In some embodiments, the frame 1 includes a pair of front wheels and rear wheels disposed below the base plate 11, a support frame 12 disposed between the front wheels and the rear wheels, and the distance between the support frame 12 and the front end of the base plate 11 is not less than half the length of the base plate 11, and the distance between the support frame 12 and the rear end of the base plate 11 is not less than one-third the length of the base plate 11.

[0069] By limiting the position of the support frame 12 on the base plate 11, on the one hand, space is left on the base plate 11 for placing steel pipes and steel materials, ensuring stability when moving steel pipes and steel materials during transportation; on the other hand, by limiting the position of the support frame 12, the center of the device is adjusted when the clamping assembly 4 clamps, loads, and hoists the steel materials and steel pipes, ensuring the stability and reliability of the device during use.

[0070] Optionally, a counterweight is provided on the base plate 11 to increase the overall stability of the device.

[0071] Optionally, the base plate 11 is provided with a handrail for pushing.

[0072] Optionally, a power system for driving the front and rear wheels to rotate is provided under the base plate 11. The power system is electrically connected to the controller 9, and the controller 9 controls the movement of the base plate 11.
