Technical Field

[0001] The invention relates to the field of transport technology, and in particular to an adaptive balancing lifting device. Background Art

[0002] Lifting devices are usually used to move goods up and down in the vertical direction. They are widely used in construction, machinery manufacturing and other fields. They can conveniently move goods at locations with height differences. With the development of technology, lifting devices are also constantly developing towards automation and intelligence.

[0003] However, the lifting devices under the existing technology usually only realize up and down movements. When the goods to be transported are not placed evenly, the lifting devices are prone to tilting, thereby affecting normal transportation and posing certain safety hazards. Summary of the invention

[0004] In order to solve the problem that the lifting device under the existing technology usually only simply realizes up and down movements, when the transported goods are not placed evenly, the lifting device is prone to tilting, thereby affecting normal transportation, and there are certain safety hazards. The specific solution is as follows.

[0005] An adaptive balancing lifting device comprises a main frame and a driving mechanism, wherein the main frame comprises a cargo platform and a guardrail, wherein the guardrail is arranged on the cargo platform and surrounds the cargo platform, wherein the cargo platform is used to carry cargo, and wherein the driving mechanism is arranged on the upper side of the main frame and is used to drive the main frame to move up and down; The driving mechanism includes a deflection adjustment disk, on which a plurality of deflection adjustment ropes and deflection adjustment wheels are arranged. The deflection adjustment wheels are arranged at equal intervals around the deflection adjustment disk. The deflection adjustment disk is also provided with a deflection adjustment motor corresponding to the deflection adjustment wheel for driving the deflection adjustment disk to rotate. One end of the deflection adjustment rope is connected to the main frame, and the other end of the deflection adjustment rope is connected to the deflection adjustment wheel. The deflection adjustment wheel can pull the deflection adjustment rope when it rotates.

[0006] By adopting the above-mentioned technical scheme, the adaptive balancing lifting device can realize the smooth up and down movement of the main frame, drive the deflection adjustment wheel to rotate through the deflection adjustment disk, adjust the tension of each deflection adjustment rope, and ensure that the main frame remains in a balanced state during the rising or falling process, thereby reducing the deflection caused by uneven weight distribution on the cargo platform, reducing the impact on transportation, and reducing safety hazards.

[0007] Optionally, the driving mechanism also includes a driving motor and a driving rope. A winding drum is provided on the rotating shaft of the driving motor. One end of the driving rope is wound on the winding drum, and the other end of the driving rope is fixedly connected to the middle part of the deflection adjustment disk. The driving motor is used to be installed on the construction floor.

[0008] By adopting the above technical solution, the arrangement of the drive motor and the drive rope enables the adaptive balancing lifting device to achieve up and down movement more efficiently, improving the driving ability and stability of the device. The drive motor winds the drive rope through the winding drum on the rotating shaft, and one end is fixedly connected to the middle of the deflection adjustment disk, so that the driving force of the drive motor can be effectively transmitted to the deflection adjustment disk, realizing the smooth lifting and lowering of the main frame.

[0009] Optionally, a torque sensor is provided on the rotating shaft of the deviation adjustment motor, the torque sensor is electrically connected to the deviation adjustment motor, and the torque sensor is used to control the operation of the deviation adjustment motor.

[0010] By adopting the above technical solution, the torque sensor can monitor the torque changes of the deviation adjustment motor in real time and feed back to the deviation adjustment motor, so that the deviation adjustment motor can adjust the working state and output power according to the actual load conditions, monitor the deviation conditions in time, and ensure that the deviation adjustment process is smooth and reliable.

[0011] Optionally, the driving rope is arranged to pass through the main frame, and the lower end of the driving rope extends out of the main frame and is provided with a limit plate, the limit plate is fixedly connected to the driving rope, and the limit plate is used to abut the bottom of the main frame.

[0012] By adopting the above technical solution, the driving rope passes through the main frame and is fixedly connected to the limiting plate. The limiting plate is used to abut the bottom of the main frame, thereby lifting the main frame from the bottom of the main frame, achieving effective limitation of the main frame, increasing the contact area, and ensuring the stability of the main frame during the lifting process.

[0013] Optionally, a support plate is also provided on the deflection adjusting rope, and the support plate is arranged on the upper side of the limiting plate. An elastic limiting member is provided on the deflection adjusting rope corresponding to the support plate. The elastic limiting member is detachably connected to the deflection adjusting rope, and the elastic limiting member is compressed to release the support plate to move toward the limiting plate.

[0014] By adopting the above-mentioned technical scheme, the position of the main frame can be effectively buffered and stabilized during the lifting process, and the shaking problem caused by the loosening of the adjustment rope can be prevented, thereby improving the safety and stability of the equipment operation. When the support plate is under too much pressure, the support plate can be released to move downward, which plays a certain buffering role, thereby alleviating the vibration and instability caused by the loosening of the adjustment rope, and the support plate is lifted up by the bottom limit plate.

[0015] Optionally, a magnet is fixedly provided on the support plate, and a corresponding magnet is also provided on the limiting plate. The magnets on the support plate and the limiting plate repel each other, and the limiting plate has a tendency to push the support plate to move upward.

[0016] By adopting the above technical scheme, mutually repelling magnets are arranged and fixed on the support plate and the limit plate respectively, so that a mutually repelling force is generated between the support plate and the limit plate, so that the limit plate has a tendency to push the support plate to move upward, thereby improving the stability of the entire device during operation. The closer the distance between the support plate and the limit plate, the greater the mutual repulsive force generated. Therefore, the main frame can be lifted upward to a certain extent when the deviation adjustment rope has not been completely lifted, thereby reducing the situation of rapid tilting.

[0017] Optionally, the elastic limiting member includes a hoop, which is detachably connected to the deviation adjustment rope, and a support rod is rotatably connected to the hoop. Multiple support rods are arranged around the hoop, and a torsion spring is arranged at the rotating connection of the support rod, and the torsion spring has a tendency to drive the support rod to move toward the support disk.

[0018] By adopting the above technical scheme, the elastic limiting member includes a hoop, which is detachably connected to the deflection adjusting rope, and a plurality of support rods are rotatably connected to the hoop. A torsion spring is provided at the rotating connection of the support rods, and the torsion spring drives the plurality of support rods to move toward the support disk, thereby achieving stable support for the deflection adjusting rope and facilitating the rapid installation and disassembly of the elastic limiting member, thereby improving the use flexibility of the lifting device. The elastic limiting member has a certain elasticity during adjustment, thereby further increasing the buffering effect of the lifting device and further improving the stability of the lifting device.

[0019] Optionally, the support plate and the main frame are provided with a clearance groove corresponding to the support rod, the clearance groove is for the support rod to pass through, the angle between the support rod and the hoop is 45 degrees when the support rod lifts the support plate, and the support rod is parallel to the hoop when it extends into the clearance groove, and the main frame and the support plate are also provided with an arc surface corresponding to the support rod, and the arc surface is used to abut the support rod.

[0020] By adopting the above technical solution, the clearance grooves arranged on the support plate and the main frame allow the support rod to pass smoothly in a pressed state without causing damage to the support rod. When the support rod lifts up the support plate 5, it forms an angle of 45 degrees with the hoop, and when the support rod extends into the clearance groove, it is parallel to the hoop. Combined with the abutment effect of the arc surface on the support rod, the stability and reliability between the support plate and the limit plate on the deviation adjustment rope are effectively improved.

[0021] Optionally, a magnetic isolation layer is provided at the bottom of the main frame, the magnetic isolation layer is used to shield the magnet, and the support plate is used to abut against the magnetic isolation layer.

[0022] By adopting the above technical solution, a magnetic isolation layer is provided at the bottom of the main frame, and the magnetic isolation layer can effectively shield the magnetic field of the magnet, thereby preventing the support plate from being adsorbed on the main frame and unable to move downward.

[0023] Optionally, a counterweight block is provided in the middle of the cargo platform, and the counterweight block is detachably connected to the cargo platform.

[0024] By adopting the above technical solution, the weight distribution of the cargo platform is made more uniform, which improves the stability during lifting; at the same time, the detachable connection design facilitates the adjustment of the position or number of the counterweight blocks according to different load requirements, further enhancing the applicability and flexibility of the device.

[0033] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0034] Embodiment 1 An adaptive balancing lifting device, such as Figure 1 and Figure 2 As shown, it includes a main frame 1 and a driving mechanism 2. The main frame 1 includes a cargo platform 11 and a guardrail 12. The guardrail 12 is arranged on the cargo platform 11 and surrounds the cargo platform 11. The cargo platform 11 is used to carry cargo. The driving mechanism 2 is arranged on the upper side of the main frame 1. The driving mechanism 2 is used to drive the main frame 1 to move up and down. In specific implementation, the guardrail 12 is connected to the cargo platform 11 by welding, and is moved up and down by the driving mechanism 2, which further improves the convenience of the product.

[0035] like Figure 2 and Figure 3 As shown, the driving mechanism 2 includes an adjustment disc 21, on which a plurality of adjustment ropes 211 and adjustment wheels 212 are arranged, and the adjustment wheels 212 are arranged at equal intervals around the adjustment disc 21. The adjustment disc 21 is also provided with an adjustment motor 213 corresponding to the adjustment wheels 212 for driving the adjustment disc 21 to rotate. One end of the adjustment rope 211 is connected to the main frame 1, and the other end of the adjustment rope 211 is connected to the adjustment wheel 212. When the adjustment wheel 212 rotates, it can pull the adjustment rope 211. In specific implementation, the adjustment disc 21 can be selected as a circular disc or a hexagonal disc, and a circular disc is preferred to ensure the uniformity of the adjustment process. The adjustment wheel 212 can use rolling bearings to reduce wear and improve efficiency, and the adjustment wheel 212 can also be made of steel to enhance its strength and durability. The deviation adjustment rope 211 can be made of high-strength steel wire rope or nylon rope. A fixed pulley 121 is provided on the guardrail 12 of the main frame 1 corresponding to each deviation adjustment rope 211. The fixed pulley 121 can play a guiding role and is more stable during deviation adjustment.

[0036] like Figure 2 and Figure 3As shown, the driving mechanism 2 also includes a driving motor 22 and a driving rope 222. A winding drum 221 is arranged on the rotating shaft of the driving motor 22. One end of the driving rope 222 is wound on the winding drum 221. The other end of the driving rope 222 is fixedly connected to the middle of the deflection adjustment disk 21. The driving motor 22 is used to be installed on the construction floor. A torque sensor 214 is arranged on the rotating shaft of the deflection adjustment motor 213. The torque sensor 214 is electrically connected to the deflection adjustment motor 213. The torque sensor 214 is used to control the operation of the deflection adjustment motor 213. In specific implementation, each deflection adjustment rope 211 is respectively arranged on the guardrail 12 in each direction. The torque sensor 214 can detect the tension of the deflection adjustment rope 211, so as to judge the load distribution at different positions, timely monitor the deflection situation, and ensure that the deflection adjustment process is smooth and reliable.

[0037] like Figure 2 and Figure 3 As shown, the driving rope 222 is set through the main frame 1, and the lower end of the driving rope 222 extends out of the main frame 1 and is provided with a limit plate 4, which is fixedly connected to the driving rope 222 and is used to abut the bottom of the main frame 1. The limit plate 4 is in the shape of a disc. In specific implementation, the limit plate 4 can be pulled up to increase the contact area, thereby lifting the main frame 1 and realizing active pulling and lifting of the main frame 1.

[0038] like Figure 1 and Figure 2 As shown, a counterweight 14 is provided in the middle of the cargo platform 11, and the counterweight 14 is detachably connected to the cargo platform 11. In specific implementation, the counterweight 14 is detachably connected by bolt connection, and the counterweight 14 makes the weight distribution of the cargo platform 11 more uniform, improves the stability during the lifting process, and at the same time, the design of detachable connection facilitates the adjustment of the position or quantity of the counterweight 14 according to different load requirements, further enhancing the applicability and flexibility of the device.

[0039] Working principle: The deflection adjustment rope 211 fixed on different guardrails 12 is detected by the torque sensor 214, the torque is determined and thus the load-bearing capacity of the cargo platform 11 is determined, and the overweight end is pulled up to achieve self-balancing, thereby improving the stability during the lifting process and reducing safety hazards.

[0040] Embodiment 2 like Figure 4As shown, the difference between the second embodiment and the first embodiment mainly lies in that a support plate 5 is also provided on the deflection adjustment rope 211, and the support plate 5 is provided on the upper side of the limiting plate 4. An elastic limiting member is provided on the deflection adjustment rope 211 corresponding to the support plate 5, and the elastic limiting member is detachably connected to the deflection adjustment rope 211. When the elastic limiting member is compressed and released, the support plate 5 moves toward the limiting plate 4. In specific implementation, the elastic limiting member can be a rubber elastic ring or an inflatable ring. When the pressure is too large, the support plate 5 can pass through the elastic limiting member. The support plate 5 can play a buffering role under the support of the elastic limiting member to improve the stability of the support. The support plate 5 on the deflection adjustment rope 211 can lift the main frame 1, and when the pressure is too large, it will be released to play a buffering role, thereby improving the stability.

[0041] like Figure 4 As shown, a magnet 41 is fixedly provided on the support plate 5, and a corresponding magnet 41 is also provided on the limit plate 4. The support plate 5 and the magnets 41 on the limit plate 4 repel each other, and the limit plate 4 has a tendency to push the support plate 5 to move upward. In specific implementation, the support plate 5 can move toward the main frame 1 under the mutual repulsion of the magnets 41 of the limit plate 4, thereby improving the supporting effect, and after the elastic limiter releases the support plate 5, the closer the distance between the support plate 5 and the limit plate 4, the greater the repulsion, and the main frame 1 can be lifted to a certain extent when it is deflected.

[0042] like Figure 4 As shown, a magnetic isolation layer 13 is provided at the bottom of the main frame 1, and the magnetic isolation layer 13 is used to shield the magnet 41, and the support plate 5 is used to abut the magnetic isolation layer 13. In specific implementation, the magnetic isolation layer 13 can be made of copper or lead, which can effectively reduce the situation where the magnet 41 is adsorbed on the main frame 1 and affects the effect of lifting the main frame 1.

[0043] Working principle: The basic working principle is the same as that of the first embodiment, but the support plate 5 and the magnet 41 are added, which can increase the buffering effect to a certain extent, reduce the instantaneous tilt, and further reduce the safety hazard.

[0044] Embodiment 3 like Figure 5 As shown, the main difference between the third embodiment and the first embodiment is that the elastic limiter of the third embodiment includes a hoop 51, which is detachably connected to the deflection adjustment rope 211, and a support rod 511 is rotatably connected to the hoop 51. A plurality of support rods 511 are arranged at equal intervals around the hoop 51, and a torsion spring is arranged at the rotation connection of the support rod 511, which has a tendency to drive the support rod 511 to move toward the support plate 5. In specific implementation, the support rod 511 can support the support plate 5, so that the support plate 5 can pull the product.

[0045] like Figure 5As shown, the support plate 5 and the main frame 1 are provided with a clearance groove 52 corresponding to the support rod 511, and the clearance groove 52 is for the support rod 511 to pass through. When the support rod 511 lifts the support plate 5, the angle between the support rod 511 and the hoop 51 is 45 degrees and cannot be further reduced. When the support rod 511 extends into the clearance groove 52, it is parallel to the hoop 51. The main frame 1 and the support plate 5 are also provided with an arc surface 53 corresponding to the support rod 511, and the arc surface 53 is used to abut the support rod 511. In specific implementation, the arc surface 53 can guide the support rod 511 to extend into the clearance groove 52, thereby reducing the situation where the support rod 511 interferes with the main frame 1 or the support plate 5 and is damaged.

[0046] Working principle: The basic working principle is the same as that of the second embodiment, and the elastic support member is further improved to stably support and release the support plate 5.

[0047] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
