[0002] Homemade partitions are made of different materials to separate spaces. This type of partition can be used in many fields, including but not limited to home storage, office organization, and medical care file classification and storage. After the homemade partition is produced, it is an efficient and safe method to use a crane balance beam to complete the handling, loading and unloading and stacking of the homemade partition. The crane balance beam is a device specially designed for lifting heavy goods. It can stably lift and move the goods through the lifting rope and hook.

[0003] In order to ensure the stability of the split board when it is suspended in the air, the existing homemade split board lifting device basically tries to make a support plate from the bottom of the split board to prevent the split board from falling. However, the existing support plates are directly inserted into the bottom of the split board from the side, which may cause damage to the edge surface of the bottom side of the split board, thereby destroying the appearance; therefore, it does not meet the existing needs. In this regard, we propose a homemade split board lifting device. Summary of the invention

[0013] As an optional scheme for a self-made panel lifting device described in the present invention, rope grooves are symmetrically opened on the lifting beam, the winding rod is located at one end of the two rope grooves close to the central rotating shaft, and the other ends of the two rope grooves are installed with pulley seats, and two lifting ropes are also provided, one end of the two lifting ropes is connected to the bottom center of the lifting beam, and the other ends of the two lifting ropes are respectively wound around the two winding rods, and the middle part of the lifting rope is in contact with the pulley seat.

[0017] As an optional solution of a self-made split-plate hoisting device described in the present invention, wherein: the support palm is configured as an arc-shaped plate with a curved edge on one side, and the curved edge of the support palm is chamfered;

[0018] In normal state, the palm support is received in the hidden groove, and there is a gap between the edge of the palm support and the clamping wall of the clamping shift plate.

[0019] The present invention has the following beneficial effects:

[0020] 1. The self-made split plate lifting device can make the clamping and moving plates on both sides move closer or farther away at the same time through the meshing of the first rack, the second rack and the active gear, so as to control the clamping of the self-made split plate. Through the setting of the paddle gear and the passive rack, when the clamping and moving plate stably clamps the self-made split plate, the first rack and the second rack cannot continue to move closer. At this time, the paddle column will overcome the force of the resistance spring, thereby driving the paddle plate to move, so that the paddle gear rotates relative to the active gear, and the support plate rotates relative to the clamping and moving plate, so that the support plate is automatically unfolded after the self-made split plate is clamped by the present lifting device, thereby increasing the safety and reliability during lifting.

[0021] Unlike the prior art, the present invention utilizes a lifting rope, and drives a winding rod to wind up the lifting rope through a central rotating shaft, so that before the pallet is unfolded, the lifting rope will be wound up, thereby lifting the self-made split board to create a height off the ground or a height off the board below, which is convenient for the subsequent unfolding and insertion of the pallet, making the use of the pallet smoother, reducing the environmental pressure and friction during the operation of the device, and improving the lifting stability and protection of the self-made split board and the device itself.

[0022] 2. The self-made split board hoisting device divides the support plate shaft into an active rod and an output rod, and the output rod is driven by the passive rack, and the active rod is threadedly matched with the threaded hole, so that when the passive rack moves, the active rod rotates and moves downward, so that the height of the support plate changes when it rotates, and the support plate actively moves downward and rotates, thereby reducing the friction between the support plate and the bottom of the self-made split board, further solving the problem of the wear of the self-made split board when the support plate is inserted in the prior art; the self-made split board is lifted off the ground with the help of the lifting rope, and the downward movement and rotation effect of the support plate is better;

[0023] Moreover, by setting the edge of the palm support as a curve and chamfering it, the stress concentration when the palm support contacts the self-made splitter is reduced, thereby reducing the risk of wear. In addition, when the palm support is set to normal state, there is a distance between the palm support and the side wall of the clamping shift plate, leaving a certain space for the downward movement of the pallet, ensuring that the pallet will contact the self-made splitter only after it moves down to a certain extent, thereby further ensuring the protection of the self-made splitter and the device itself during the lifting process.

[0024] 3. The homemade split plate lifting device sets a spiral spring between the winding gear and the winding rod, so that when the central shaft starts to rotate, the rotation of the winding gear will be absorbed by the spiral spring, and when the clamping of the homemade split plate by the clamping plate reaches the clampable degree, the spiral spring is compressed to the extreme, thereby starting the winding rod to rotate the winding rope and triggering the lifting of the device, so that the lifting step is after the clamping to prevent lifting when the clamping force is insufficient, and by setting the clamping plate as a splint with an elastic layer, the presence of the elastic layer can be used to increase the clamping buffer of the clamping plate to the homemade split plate, thereby extending the process from clampable to stable clamping, leaving enough time for triggering the rotation of the support plate, so that the mechanical triggering and operation of the device are smoother and more reasonable, and the clamping of the homemade split plate is further improved, making the lifting safer and more reliable.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1: This embodiment is intended to promote the solution of the problem that in order to ensure the stability of the split board when it is suspended in the air, a support plate is basically made from the bottom of the split board to prevent the split board from falling. However, the existing support plates are directly inserted into the bottom of the split board from the side, which may cause damage to the surface of the bottom edge of the split board, thereby destroying the appearance. Please refer to Figure 1-Figure 11A self-made split plate lifting device comprises a hanging beam 10, a lifting beam 20 is arranged at the bottom of the hanging beam 10, a lifting rope 40 is connected between the hanging beam 10 and the lifting beam 20, a clamping and moving plate 30 for clamping the self-made split plate is slidably installed at both ends of the lifting beam 20, a central rotating shaft 130 is rotatably installed on the lifting beam 20, a driving motor 50 for driving the central rotating shaft 130 to rotate is arranged on the lifting beam 20, a winding rod 161 for winding up the hanging rope 40 is installed on the lifting beam 20, the winding rod 161 is transmission-connected with the central rotating shaft 130, a driving gear 140 is coaxially installed on the central rotating shaft 130, a first rack 410 and a second rack 420 respectively connected to two clamping and moving plates 30 are slidably installed on the bottom side of the lifting beam 20, the first rack 410 , and the second rack 420 are meshed with the driving gear 140. A hidden groove 310 is opened on the bottom side of the clamping and shifting plate 30. A support plate 60 for supporting the self-made split plate is rotatably installed in the hidden groove 310. The support plate 60 is transmission-connected to the central rotating shaft 130. After the winding rod 161 starts to wind up the sling 40, the support plate 60 rotates and extends out.

[0039] Two support frames 510 are installed on the lifting beam 20, and an active worm 110 is rotatably installed between the support frames 510. The driving motor 50 is installed on the side of one of the support frames 510 and connected to the active worm 110. A worm wheel 120 is installed on the top of the central rotating shaft 130, and the active worm 110 is meshed with the worm wheel 120.

[0040] For specific settings, see Figure 5 , clamping grooves 210 are provided at both ends of the lifting beam 20, and the clamping moving plate 30 is slidably engaged with the clamping grooves 210, and plate edges 190 are installed on both sides of the clamping moving plate 30, and the first rack 410 and the second rack 420 are both slidably installed with the plate edges 190, and passive racks 430 are slidably installed on the two plate edges 190, respectively, and the two passive racks 430 are respectively slidably fitted with the bottom sides of the first rack 410 and the second rack 420, and the end of the passive rack 430 is slidably plugged with the clamping moving plate 30, and the passive rack 430 is transmission-connected to the support plate 60.

[0041] The meshing design of the driving gear 140 and the first rack 410 and the second rack 420 enables the clamping and moving plates 30 on both sides to move together or apart at the same time, thus achieving stable clamping of the self-made split board. This clamping method is not only easy to operate, but also has uniform clamping force, effectively preventing the self-made split board from shaking or slipping during the hoisting process.

[0042] See Fig.10A disc 450 is coaxially mounted on the central rotating shaft 130, a lever 460 is mounted at the bottom of the disc 450, an arc-shaped slide groove 141 is opened on the driving gear 140, and the lever 460 is inserted and slidably installed inside the arc-shaped slide groove 141. A paddle gear 440 is rotatably mounted on the central rotating shaft 130, the paddle gear 440 is located at the bottom side of the driving gear 140, the paddle gear 440 is meshed with the passive rack 430, and a paddle plate 441 is integrally arranged on the paddle gear 440, the paddle plate 441 is slidably mounted with the arc-shaped slide groove 141, and a resistance spring 470 is installed between the paddle plate 441 and the arc-shaped slide groove 141.

[0043] By setting a resistance spring 470 in the arc-shaped slide groove 141, the driving gear 140 and the thumbwheel gear 440 keep rotating synchronously in normal state, so that the passive rack 430 moves synchronously with the first rack 410 and the second rack 420, and the state of the support plate 60 will not be changed, so that it will not be triggered prematurely.

[0044] Normally, see Figure 2 and Figure 8 , the resistance spring 470 is naturally relaxed, and the shift plate 441 and the shift post 460 are in conflict;

[0045] When clamping the shift plate 30 to stably clamp the self-made split plate, see Figure 3 , Fig. 9 , the lever column 460 overcomes the force of the resistance spring 470, the paddle gear 440 rotates relative to the active gear 140, and the passive rack 430 drives the support plate 60 to rotate and extend.

[0046] The first rack 410 and the second rack 420 are both mounted with a first fixing plate 480 on their sides, the two passive racks 430 are mounted with a second fixing plate 490 on their sides, and a tension spring 491 is mounted between the second fixing plate 490 and the first fixing plate 480 for the passive rack 430 to remain relatively still with the first rack 410 and the second rack 420 when the passive rack 430 is in a normal state.

[0047] When the first gear 410 is engaged with the second gear 420 and the driving gear 140, the first gear 410 and the second gear 420 are engaged with the driving gear 140, and the clamping plates 30 on both sides are brought closer or farther away from each other, thereby controlling the clamping of the self-made split plate. When the clamping plate 30 stably clamps the self-made split plate, the first gear 410 and the second gear 420 cannot continue to be brought closer. At this time, the lever 460 will overcome the force of the resistance spring 470, thereby driving the lever 441 to move, so that the lever gear 440 rotates relative to the driving gear 140, and the support plate 60 rotates relative to the clamping plate 30, thereby realizing that after the lifting device completes the clamping of the self-made split plate, the support plate 60 is automatically unfolded, thereby increasing the safety and reliability during lifting.

[0048] Different from the prior art, the present invention utilizes the lifting rope 40, and drives the winding rod 161 to wind up the lifting rope 40 through the central rotating shaft 130, so that before the pallet 60 is unfolded, the lifting rope 40 will be wound up, thereby lifting the self-made split board to create a height off the ground or a height off the board below, which is convenient for the subsequent unfolding and insertion of the pallet 60, making the use of the pallet 60 smoother, reducing the environmental pressure and friction during the operation of the device, and improving the lifting stability and the protection of the self-made split board and the device itself.

[0049] Embodiment 2: This embodiment is intended to solve the problem that if clamping and lifting are performed simultaneously, the clamping may be empty or unstable. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 11 The clamping and moving plate 30 is configured as a clamping plate with an elastic layer on the clamping surface, a central gear 150 is coaxially mounted on the central rotating shaft 130, two winding rods 161 are provided, and the two winding rods 161 are arranged on both sides of the central rotating shaft 130, a winding gear 160 is installed on the winding rod 161, and a spiral spring 162 is installed between the winding gear 160 and the winding rod 161 for delaying the winding time, and the two winding gears 160 are meshed with the central gear 150. In this embodiment, the elastic layer can be a sponge layer, a rubber layer, or a flat plate with a spring.

[0050] The time point when the winding rod 161 starts to rotate is later than the time point when the elastic layer of the clamping and shifting plate 30 starts to be compressed, and the time point when the winding rod 161 starts to rotate is earlier than the time point when the supporting plate 60 rotates.

[0051] During the specific setting, rope grooves 170 are symmetrically opened on the lifting beam 20, and the winding rod 161 is located at one end of the two rope grooves 170 close to the central rotating shaft 130. The other ends of the two rope grooves 170 are installed with pulley seats 180. Two suspension ropes 40 are also provided, and one end of the two suspension ropes 40 is connected to the bottom center of the suspension beam 10, and the other ends of the two suspension ropes 40 are respectively wound on the two winding rods 161, and the middle part of the suspension rope 40 is in contact with the pulley seat 180.

[0052] When the clamping of the self-made split plate by the clamping plate 30 reaches the clampable degree, the spiral spring 162 is compressed to the extreme, thereby opening the winding rod 161 to rotate the winding rope 40, triggering the lifting of the device, so that the lifting step is after the clamping to prevent lifting when the clamping force is insufficient, and by setting the clamping plate 30 as a splint with an elastic layer, the existence of the elastic layer can be used to increase the clamping buffer of the clamping plate 30 on the self-made split plate, thereby extending the process from clampable to stable clamping, and leaving enough time for triggering the rotation of the support plate 60. In this way, the mechanical triggering and operation of the device are smoother and more reasonable, and the clamping of the self-made split plate is further improved, making it safer and more reliable during lifting.

[0053] Embodiment 3: This embodiment is intended to solve the problem that if the support plate 60 is directly unfolded, the support plate 60 will collide with the self-made split plate. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 11 The clamping and moving plate 30 is configured as a clamping plate with a space inside, and a transmission shaft 710 is rotatably installed inside the clamping and moving plate 30. A transmission gear 720 and a first rotating wheel 730 are coaxially installed on the transmission shaft 710. The passive rack 430 is configured as a rack with teeth at both ends. The passive rack 430 is meshed with the transmission gear 720. A second rotating wheel 740 is arranged on the support plate 60, and a belt 750 is installed between the first rotating wheel 730 and the second rotating wheel 740. A threaded hole 320 is opened in the clamping and moving plate 30, and the support plate 60 is threadedly connected to the threaded hole 320.

[0054] See Figure 6 The support plate 60 includes a support palm 62 for supporting the homemade split plate, a support seat 61 is installed at one end of the support palm 62, and an axle rod 63 is installed on the support seat 61. The axle rod 63 is divided into an active rod 631 fixedly connected to the support seat 61, and an output rod 632 connected to the second rotating wheel 740. The output rod 632 is slidably plugged into the active rod 631, and a threaded section 64 is provided on the surface of the output rod 632 for cooperating with the threaded hole 320.

[0055] The palm support 62 is configured as an arc-shaped plate with a curved edge on one side, and the curved edge of the palm support 62 is chamfered; in normal state, the palm support 62 is received in the hidden groove 310, and there is a gap between the edge of the palm support 62 and the clamping wall of the clamping shift plate 30.

[0056] In this embodiment: by setting the support plate 60 as a combination of the support seat 61, the support palm 62, and the shaft rod 63, the design of the support plate 60 is more refined, and by dividing the shaft rod 63 into an active rod 631 and an output rod 632, and the output rod 632 is transmitted with the passive rack 430, and the active rod 631 is threadedly matched with the threaded hole 320, so that when the passive rack 430 moves, the output rod 632 rotates, and through the sliding connection between the two, the active rod 631 is rotated while moving downward, so that the height of the support plate 60 changes when it rotates, and the support plate 60 actively moves downward and rotates, thereby reducing the friction between the support plate 60 and the bottom of the self-made split plate, further solving the problem of wear on the appearance of the self-made split plate when the support plate is inserted in the prior art; the self-made split plate is lifted off the ground with the help of the hanging rope 40, and the downward movement and rotation effect of the support plate 60 is better;

[0057] Moreover, by setting the edge of the support 62 as a curve and a chamfer, the stress concentration when the support contacts the self-made split plate can be effectively reduced, thereby reducing the risk of wear. In addition, when the support 62 is in the normal state, there is a distance between the side wall of the clamping shift plate 30, leaving a certain space for the downward movement of the support plate 60, ensuring that the support plate 60 will contact the self-made split plate only after it moves down to a certain extent, thereby further ensuring the protection of the self-made split plate and the device itself during the lifting process.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
