Detailed Implementation

[0021] The technical solutions of 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The core of this application is to provide a lifting and hoisting device that is highly convenient to move.

[0023] This application provides a lifting and hoisting device, including a load-bearing component 1, a lateral movement component 3, and a lifting component 2. The load-bearing component 1 includes two trolleys 11 and a lifting component 12; at least one of the two trolleys 11 is reciprocating along the X-direction, and both trolleys 11 include a liftable lifting bracket 111; the lifting component 12 is used to lift a product 4 and is located at the movable end of the two lifting brackets 111; the lifting component 2 is located on the load-bearing component 1 and is used to drive the movable ends of the two lifting brackets 111 to move up and down along the Y-direction; the lateral movement component 3 is connected to the two trolleys 11 and is used to adjust the distance between the two trolleys 11 along the X-direction.

[0024] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 16 The load-bearing component 1 is the main body of the equipment. Two trolleys 11 are arranged along the X direction, and at least one of them is configured to reciprocate along the X direction. Meanwhile, the main body of the trolley 11 is a lifting bracket 111, which is a bracket that can extend and retract along the Y direction. Its fixed end is close to the ground to provide support, while it is movably and slidably set above the fixed end. Correspondingly, the lifting component 12 is set at the movable end of the two lifting brackets 111. Thus, the extension and retraction of the lifting brackets 111 can drive the lifting component 12 to rise and fall along the Y direction.

[0025] The lifting assembly 2 and the traverse assembly 3 are the power mechanisms that drive the two trolleys 11 to move. The lifting assembly 2 is a mechanism with Y-axis motion, which can push or pull the movable end of the lifting bracket 111 upward. It can be a winch mechanism or a scissor lift, etc. The traverse assembly 3 is a mechanism with X-axis motion, which can drive the left trolley 11 to move to the right and / or the right trolley 11 to move to the left, so as to achieve the distance between the two trolleys 11 along the X-axis.

[0026] In summary, when the equipment needs to be moved, the lifting assembly 2 can be activated to lower the height of the movable end of the lifting bracket 111, thereby lowering the height of the equipment; and the lateral movement assembly 3 can be activated to reduce the distance between the two trolleys 11 along the X direction, thereby reducing the width of the equipment, so that the equipment can be completely retracted to its original position. Figure 14 After the state shown, the volume of the device, compared to the device as shown... Figure 1 , Figure 5 The volume of the unfolded state shown is significantly reduced, which is beneficial for packing or passing through narrow spaces, and greatly improves the ease of moving the lifting device.

[0027] It should be noted that the movement of the trolley 11 along the X direction is not limited, as long as the movement requirements are met and the volume of the device after being folded up is not significantly increased. For example, the supporting component 1 also includes a foldable base plate. For instance, when both trolleys 11 can move along the X direction, the base plate is a three-fold plate. The unfolded base plate has two slide rails extending along the X direction. Two slider structures arranged at intervals along the Z direction on the bottom of the trolley 11 slide and engage with the corresponding slide rails. Then, the two trolleys 11 are movably set on the base plate through four slider structures. After the two trolleys 11 move towards each other to the closest position at the end of their stroke, the four slider structures are all located in the middle plate of the three plates arranged in sequence along the X direction on the base plate. The plates on both sides of the three plates arranged in sequence along the X direction can be erected and located on both sides of the trolley 11.

[0028] Preferably, please refer to Figure 4 , Figure 7 , Figure 10 , Figure 13 , Figure 16 The lifting assembly 2 includes two telescopic rods 21, which are mounted on the lifting brackets 111 of the corresponding trolley 11. Specifically, the fixed end of the telescopic rod 21 is fixed to the fixed end of the lifting bracket 111, and the movable end of the telescopic rod 21 is connected to the movable end of the lifting bracket 111. For example, the hanging ring of the movable end of the telescopic rod 21 is installed on the movable end of the lifting bracket 111 through a pin 22. In summary, using the lifting assembly 2 which includes two telescopic rods 21 is beneficial to reducing the size of the equipment and expanding its functions, enabling it to lift and support the target product 4.

[0029] Preferably, the telescopic rod 21 is an electric push rod; more specifically, the telescopic rod 21 is an electric lead screw. Of course, the telescopic rod 21 in this application is not limited to an electric push rod; it can also be a hydraulic rod, a pneumatic rod, etc.

[0030] Based on the above embodiments, the lateral movement assembly 3 includes a scissor beam assembly 31 and a drive assembly 32; each of the two lifting supports 111 has a guide rail 11121, which extends along the Z direction; the four ends of the scissor beam assembly 31 are movably inserted into the guide rails 11121 of the two trolleys 11, and the guide rails 11121 are used to guide the corresponding ends of the scissor beam assembly 31 to move along the Z direction; the drive assembly 32 is drivenly connected to the corresponding ends of the scissor beam assembly 31 to drive the scissor beam assembly 31 to open and close.

[0031] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 14 , Figure 16 In the scissor beam assembly 31, the two connecting beams 311 are connected at the midpoint of their lengths via a pivot 312. Each of the two connecting beams 311 has one end slidably fitted to the guide rail 11121 of one trolley 11 and the other end slidably fitted to the guide rail 11121 of the other trolley 11, forming a four-point support. Correspondingly, the output end of the drive assembly 32 is connected to one end of at least one connecting beam 311, and is used to drive the end of the connected beam 311 connected to it to move along the guide rail 11121, so that the scissor beam assembly 31 opens and closes, thereby realizing the adjustment of the distance between the two trolleys 11 in the X direction.

[0032] Based on the above embodiments, both trolleys 11 also include a number of electric casters 112; in one trolley 11, a number of electric casters 112 are located at the bottom of the lifting support 111.

[0033] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 16Each of the two trolleys 11 is equipped with a plurality of electric casters 112, and the plurality of electric casters 112 on each trolley 11 are located at the bottom of the lifting bracket 111 of the same trolley 11. This can meet the requirement of adjusting the distance between the two trolleys 11 in the X direction; and when the distance between the two trolleys 11 in the X direction is adjusted by the transverse component 3, the electric casters 112 are activated to drive the two trolleys 11 to move in the X direction, preventing the trolleys 11 from being unstable in the X direction, and preventing the two trolleys 11 from tipping over in the Z direction due to the pull of the transverse component 3; at the same time, it meets the equipment transfer requirements, and can also transfer the product 4 after loading. Preferably, the plurality of electric casters 112 in one trolley 11 are arranged sequentially in the Z direction.

[0034] Because it uses electric casters 112 with swivel function, the device can not only move in any horizontal direction, but also turn in place. It can pass through curves with a very small turning radius. Compared with related technologies, the device has higher passability and flexibility. At the same time, it greatly improves operating efficiency and helps to save on operating costs. Furthermore, the electric casters 112 can be braked after the device is unfolded or retracted to ensure the device's state is maintained.

[0035] Preferably, the electric caster wheel 112 is capable of braking; furthermore, correspondingly, the lifting bracket 111 is a flat frame or a straight frame (as shown in the image). Figure 2 , Figure 3 , Figure 6 , Figure 9 , Figure 12 , 15 As shown, the projection of the lifting bracket 111 along the Y direction is a narrow rectangle.

[0036] Based on the above embodiments, the drive assembly 32 includes four power components 321, two racks 322, and four gears 323; the two racks 322 are disposed on the corresponding carriages 11, and both racks 322 extend along the Z direction; the four gears 323 are rotatably disposed on the corresponding carriages 11, and the four gears 323 mesh with the racks 322 disposed on their respective carriages 11; and the four ends of the scissor beam assembly 31 are connected to the corresponding gears 323; the four power components 321 are drivenly connected to the corresponding gears 323.

[0037] Please refer to Figure 4 , Figure 7 , Figure 16Both trolleys 11 have guide rails 11121 that are grooves, preferably anti-disengagement. The guide rails 11121 of both trolleys 11 are located at their top, i.e., the guide rails 11121 are located on the top beam of the lifting bracket 111. Correspondingly, in the drive assembly 32, one of the two racks 322 is fixed inside the guide rail 11121 of one trolley 11, and the other is fixed inside the guide rail 11121 of the other trolley 11. Both guide rails 11121 and the two racks 322 extend along the Z direction and are located at the top of the corresponding trolley 11. At the same time, two of the four gears 323 are rotatably inserted inside the guide rail 11121 of one trolley 11, and the remaining two are rotatably inserted inside the guide rail 11121 of the other trolley 11. The four gears 323 mesh with the racks 322 in their respective guide rails 11121 for transmission.

[0038] Correspondingly, four gears 323 are connected one-to-one to the four ends of the scissor beam assembly 31. When the gears 323 rotate, they can drive the corresponding ends of the scissor beam assembly 31 to move along the guide rail 11121. In order to drive the gears 323 to rotate, the drive assembly 32 is equipped with a power component 321, which can be a motor or electric motor. The four power components 321 are fixed one-to-one to the ends of the scissor beam assembly 31, and the output end of the power component 321 is connected to the gear 323 located at its bottom to drive the connected gear 323 to rotate.

[0039] In some embodiments, please refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 10 , Figure 12 , Figure 14 , Figure 16 The output shaft of the power component 321 is connected to the gear 323 located below it by means of key connection or interference fit, and a bearing 324, preferably a thrust bearing, is sleeved on the outside of the output shaft of the power component 321. The bottom end of the bearing 324 is movably abutted against the trolley 11.

[0040] Furthermore, the end of the connecting beam 311 has a connecting lug, and the middle position of the connecting lug has a through hole. After the output shaft of the power component 321 passes through the connecting lug, it is connected to the gear 323 for transmission.

[0041] Preferably, the power unit 321 includes a motor and a brake, wherein the brake disc of the brake is drivenly connected to the output shaft of the motor so that braking can be achieved by the brake after the device is deployed or retracted, keeping the gear 323 locked in the current position of the rack 322 so that the scissor beam assembly 31 remains in the current X shape.

[0042] Please refer to Figure 11 , Figure 12, Figure 13 Based on the above embodiments, the lifting assembly 12 includes a hoisting assembly 121 and a lifting assembly 122; the hoisting assembly 121 is used to lift the product 4 upwards; the lifting assembly 122 is used to lift the product 4 upwards. Thus, this equipment can not only hoist the product 4, but also lift the product 4, saving the factory the cost of having to purchase a separate hoisting equipment and a separate lifting equipment.

[0043] It should be noted that there are no restrictions on the types of lifting assembly 121 and jacking assembly 122, as long as they can meet the intended functions.

[0044] Based on the above embodiments, the scissor beam assembly 31 includes two connecting beams 311, which are rotatably connected at the midpoint of their lengths; the lifting assembly 121 includes a plurality of lifting lugs 1211, which are disposed on the sides of the corresponding connecting beams 311.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 13 , Figure 14 , Figure 15 , Figure 16 In the scissor beam assembly 31, the connecting beam 311 is provided with a plurality of lifting lugs 1211 along its own length direction, and the lifting lugs 1211 are located on the side of the connecting beam 311. Optionally, such as Figure 1 , Figure 2 , Figures 4 to 7 , Figures 14 to 16 As shown, the connecting beam 311 is provided with a lifting lug 1211 on one side along the transverse direction. Optionally, as follows: Figure 3 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13 As shown, the connecting beam 311 is provided with lifting lugs 1211 on both sides along the transverse direction.

[0046] Furthermore, a lifting through hole is provided in the middle of the lifting lug 1211 for attaching a fastener or... Figures 8 to 10 Product 4 is suspended using methods such as hanging rings. In use, after suspending product 4 on the device, the lifting assembly 2 is activated to raise and lower product 4.

[0047] Based on the above embodiments, the lifting assembly 122 includes a bracket 1221 and a quick-release assembly 1222; the bottom of the bracket 1221 has a plurality of connecting feet 12212, which are detachably connected to the corresponding lifting lugs 1211 via the quick-release assembly 1222; the top of the bracket 1221 has a positioning part 12211 for positioning the product 4.

[0048] Please refer to Figure 11 , Figure 12 , Figure 13 The bracket 1221 is the main load-bearing component of the lifting assembly 122. The bracket 1221 has a positioning part 12211. When the bracket 1221 is placed on top of the scissor beam assembly 31 and is in the working position, the positioning part 12211 is located at the top and is used to position the product 4 placed on the bracket 1221.

[0049] Preferably, the positioning part 12211 includes Figure 11 , Figure 12 , Figure 13 The positioning corner plates shown can be triangular or rectangular, with four plates positioned at the four corners of the rectangular area. In use, product 4 can be placed between the four positioning corner plates.

[0050] Optionally, the positioning part 12211 can be a base, and the top surface of the positioning part 12211 is a contoured surface of the outer surface of the target product 4. For example, when the target product 4 is a cylindrical product 4, the top surface of the positioning part 12211 is an arc surface, or when the target product 4 is a rectangular columnar product 4, the top surface of the positioning part 12211 is a U-shaped surface. In use, the product 4 can be placed on the positioning part 12211.

[0051] Of course, the positioning unit 12211 is not limited to the above optional embodiments, as long as it can achieve the intended function of the positioning product 4.

[0052] Furthermore, the bracket 1221 has several connecting feet 12212, each with mounting through holes. When the bracket 1221 is placed on top of the scissor beam assembly 31 and in the working position, the mounting through holes of the connecting feet 12212 are aligned with the through holes of the corresponding lifting lugs 1211. Correspondingly, the quick-release assembly 1222 includes several connecting rods for inserting into or retracting from the mounting through holes of the corresponding connecting feet 12212 and the through holes of the corresponding lifting lugs 1211. When it is necessary to lift the product 4, the bracket 1221 is placed on top of the scissor beam assembly 31, aligning the mounting through holes of the connecting feet 12212 with the through holes of the corresponding lifting lugs 1211. Then, the quick-release assembly 1222 is used to fix the bracket 1221. When the bracket 1221 is not needed, the quick-release assembly 1222 can be removed first, and then the bracket 1221 can be taken off.

[0053] It should be noted that the specific composition of the quick-release assembly 1222 is not limited, as long as it enables the disassembly and assembly of the bracket 1221 and the lifting assembly 121. For example, the connecting rod in the quick-release assembly 1222 may be a bolt, and the mounting through hole of the connecting foot 12212 may have a threaded section. After the head end of the connecting rod passes through the through hole of the lifting lug 1211, it can be screwed into the threaded section of the mounting through hole. Alternatively, the connecting rod in the quick-release assembly 1222 may be a bolt, and the quick-release assembly 1222 may also include several nuts. After the connecting rod passes through the mounting through hole of the corresponding connecting foot 12212 and the through hole of the corresponding lifting lug 1211, the nuts can be connected to the head end of the connecting rod.

[0054] It should be noted that the types of lifting lugs 1211 and connecting feet 12212 are not limited, as long as they can meet the intended functions. Optionally, both lifting lugs 1211 and connecting feet 12212 are flat lifting lugs. Preferably, lifting lugs 1211 are flat lifting lugs, and connecting feet 12212 are U-shaped lifting lugs. When the bracket 1221 is placed on top of the scissor beam assembly 31 and is in the working position, several connecting feet 12212 span across the corresponding lifting lugs 1211, such as... Figure 11 and Figure 13 As shown.

[0055] Based on the above embodiments, both lifting supports 111 include a bottom beam 1111, a top beam 1112, and at least two telescopic beams 1113; in one lifting support 111, the bottom beam 1111 is parallel to the top beam 1112 and extends along the Z direction; several telescopic beams 1113 extend along the Y direction and are connected to the bottom beam 1111 and the top beam 1112, and the several telescopic beams 1113 are arranged at intervals along the Z direction; the lifting assembly 2 includes two telescopic rods 21, one telescopic rod 21 is connected to the bottom beam 1111 and the top beam 1112 in one lifting support 111, and the other telescopic rod 21 is connected to the bottom beam 1111 and the top beam 1112 in the other lifting support 111.

[0056] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 16 The lifting support 111 uses a flat frame. Specifically, the top beam 1112 is located directly above the bottom beam 1111, and both extend along the Z-direction. The telescopic beam 1113 is located between the top beam 1112 and the bottom beam 1111, with its lower fixed end connected to the bottom beam 1111 and its upper movable end connected to the top beam 1112. Therefore, when in use, the device, when retracted, forms... Figure 14 The sheet-like structure shown allows for rapid passage through narrow channels.

[0057] Furthermore, the telescopic beam 1113 is a hollow beam; a trolley 11 has three telescopic beams 1113, and the three telescopic beams 1113 in a trolley 11 are arranged sequentially along the Z direction, and the telescopic rod 21 provided in a trolley 11 is built into the middle one of the three telescopic beams 1113 arranged along the Z direction in the trolley 11.

[0058] In summary, because this equipment can be folded up, more units can be transported using containers compared to related technologies, such as two, three, or four units. Furthermore, when not in use, the equipment can be folded up and placed against a wall, occupying less space compared to related technologies, thus significantly reducing construction and storage costs. Additionally, because the equipment is easily relocatable, using it can save on the cost of purchasing cranes compared to related technologies.

[0059] In some embodiments, the width of the device in the X direction when it is fully retracted is 1 / 5 of the width of the device in the X direction when it is fully extended, and the height of the device in the Y direction when it is fully retracted is 1 / 2 of the height of the device in the Y direction when it is fully extended.

[0060] Building upon the above embodiments, a signal receiver and a controller are also included. The signal receiver receives control commands, including retracting and extending commands. The retracting command controls the movable ends of the two lifting supports 111 to lower along the Y-axis and reduces the distance between the two trolleys 11 along the X-axis. The extending command controls the distance between the two trolleys 11 to increase along the X-axis. Correspondingly, the controller is connected to the signal receiver, lifting assembly 2, lateral movement assembly 3, and electric caster wheels 112. Based on the control commands, the controller controls the movement of the lifting assembly 2, lateral movement assembly 3, and electric caster wheels 112, providing the hardware basis for automatically controlling and executing the control commands upon receipt. This enables automatic adjustment of the device.

[0061] Optionally, after receiving the retraction command, the controller controls the transverse component 3 and the electric omnidirectional wheel 112 to start, so as to synchronously drive the two trolleys 11 to move towards each other in the X direction; and controls the lifting component 2 to start, so as to drive the movable end of the lifting bracket 111 to lower in the Y direction.

[0062] Optionally, after receiving the unfolding command, the controller controls the transverse component 3 and the electric omnidirectional wheel 112 to start, so as to synchronously drive the two trolleys 11 to move in opposite directions along the X direction; it can also optionally control the lifting component 2 to start, so as to drive the movable end of the lifting bracket 111 to lower along the Y direction.

[0063] It should be noted that during the execution of the retract and unfold commands, controlling the movement of the two trolleys 11 along the X-axis and controlling the movement of the movable end of the lifting bracket 111 along the Y-axis can be performed simultaneously or sequentially.

[0064] In some embodiments, the control commands include braking commands, which are used to control the lifting assembly 2, the traversing assembly 3, and the electric caster wheel 112 to brake and lock.

[0065] In some embodiments, the control commands include lifting commands, which control the lifting assembly 2 to rise along the Y direction to lift the product.

[0066] In some embodiments, the control command includes a reset command, which controls the lifting assembly 2 to descend and reset along the Y direction to facilitate product loading.

[0067] In some embodiments, the control command includes a stop command, which is used to control the traverse assembly 3, the electric omnidirectional wheel 112, and the lifting assembly 2 to stop. After receiving the stop command, the controller controls the traverse assembly 3, the electric omnidirectional wheel 112, and the lifting assembly 2 to stop, that is, the execution of the retracting command, the unfolding command, the braking command, the lifting command, and the reset command ends.

[0068] It should be noted that there are no restrictions on the type of signal receiver, as long as it can perform the intended function.

[0069] Optionally, the signal receiver can be a control handle or an operation panel, with the control handle having a retractable button and an extendable button. In use, pressing the retractable button receives an external retractable command; pressing the extendable button receives an external extendable command. Furthermore, it may also include a brake button and / or a lifting button and / or a reset button and / or a stop button.

[0070] Optionally, the signal receiver may refer to a communication interface used to wirelessly receive control commands from the control terminal.

[0071] Furthermore, it also includes a distance detector and a height detector; the distance detector is used to detect the distance between the two trolleys 11 along the X-direction; the height detector is used to detect the height of the lifting assembly 12; the controller signal is connected to the distance detector and the height detector, and is used to control the movement of the lifting assembly 2 and the traversing assembly 3 according to the detection results of the distance detector and the height detector. This enables closed-loop control of the lifting assembly 2 and the traversing assembly 3 to ensure the accuracy of the execution of control commands.
