Description
Technical Field
[0001] This utility model relates to the field of lifting structure technology, and in particular to a center-of-gravity lifting structure for heavy objects. Background Technology
[0002] In scenarios involving the installation of heavy objects (such as battery packs), the housing of some devices cannot be designed as a fully open structure due to limited front space, which restricts the installation methods for heavy objects.
[0003] Currently, such heavy objects are generally installed using a flat-push method. This method cannot lift the center of gravity of the heavy object, resulting in a large amount of idle space at the top of the shell after installation. This space cannot be effectively utilized, ultimately wasting the installation space inside the shell and reducing the overall space utilization rate. Utility Model Content
[0004] This invention provides a structure for lifting the center of gravity of heavy objects to overcome the above-mentioned problems.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A weight-lifting structure for heavy objects includes a shell, a lifting slide, a fixing slide, and a self-locking component;
[0007] The lifting slide is obliquely arranged on both sides inside the outer shell, and the weight is installed inside the outer frame structure. The fixing slide is fixed on both sides of the outer frame structure, and the inclination angle of the fixing slide is the same as that of the lifting slide. The fixing slide has a stop hole, and the lifting slide has multiple stop holes along its extension direction. The fixing slide is equipped with a self-locking component. During the process of the fixing slide on the outer frame structure rising along the lifting slide, the self-locking component can cooperate with the stop hole to prevent the weight from falling during the lifting process. When the weight is lifted to a predetermined position at the top of the inner shell, it can be fixed inside the shell by the fixing structure. Before the weight is removed from the shell, the self-locking component can be unlocked under the action of external force.
[0008] Furthermore, the self-locking assembly includes a self-locking pin, a fixing seat, and a baffle; the self-locking pin includes an integrally formed connecting section, a transition section, and a free section;
[0009] The fixing seat is fixed to the upper surface of the fixing slide, and the fixing seat is provided with a through hole;
[0010] The free section extends downward at an angle from one end of the transition section, and the angle between the free section and the transition section is an obtuse angle; the connecting section is vertically fixed at the other end of the transition section, the connecting section is rotatably disposed at the through hole, and can reciprocate along the axial direction of the through hole, and the baffle is fixed at one end of the connecting section extending out of the through hole.
[0011] As the heavy object and the fixed slide rise along the lifting slide, under the gravity of the self-locking pin, the connecting section of the self-locking pin can rotate around the through hole, so that the free section enters the stop hole of the fixed slide and the lifting slide. As the external force continuously drives the heavy object to rise, the free section can disengage from the stop hole located at the lower part and enter the stop hole located at the upper part until the heavy object is lifted to the predetermined position.
[0012] When a heavy object needs to be removed from the housing, the connecting section can be driven to rotate in the through hole by external force, so that the free section moves out of the stop hole. The connecting section can continue to move along the axial direction of the through hole to the unlocked position under the action of external force, and can be fixed to the fixing seat by the fastener.
[0013] Furthermore, a fixing groove is provided on the fixing base along the axial direction of the through hole, and the connecting section can rotate and move axially into the fixing groove under the drive of external force;
[0014] Both the connecting section and the fixing groove are provided with tapered insertion holes; the fixing member is a tapered insertion rod, which can be inserted into the tapered insertion holes on both the connecting section and the fixing groove simultaneously to fix the connecting section to the fixing base.
[0015] Furthermore, the stop hole is an elongated hole opened along the extension direction of the fixed slide and the lifting slide.
[0016] Furthermore, the fixed slide rail includes a horizontal plate and a vertical plate disposed at one end of the horizontal plate in a vertical direction, and the stop hole is disposed on the horizontal plate;
[0017] The lifting slide includes a horizontal plate and a vertical plate located at one end of the horizontal plate in a vertical direction. The stop hole is located on the horizontal plate, and the vertical plate is fixedly connected to the outer shell. When the heavy object is lifted, the bottom surface of the horizontal plate contacts the upper surface of the horizontal plate and slides along the horizontal plate, and the side wall of the vertical plate is in contact with the side wall of the horizontal plate.
[0018] Furthermore, the fixing structure includes fixing ears and fixing plates; the fixing ears are fixed on both sides of the outer frame structure; the fixing plates are fixed on both sides inside the outer shell, and the fixing ears and fixing plates can be fixed by bolts.
[0019] Furthermore, the outer casing is provided with an operation window.
[0020] Furthermore, a handle is fixed to the outer frame structure.
[0021] Furthermore, the outer frame structure includes a frame body and a plate installed on the outside of the frame body; the frame body has a space inside for storing the heavy object; the two sides of the frame body are provided with inclined beams at the same angle as the fixed slide rail, and the vertical plate of the fixed slide rail is fixed to the outside of the inclined beams.
[0022] The beneficial effects of this utility model are:
[0023] This utility model discloses a weight lifting structure for heavy objects. By setting up a sliding cooperation and guiding relationship between a lifting slide and a fixed slide, the weight's center of gravity is lifted smoothly, ensuring stable posture and smooth sliding during the lifting process. Through the coordinated cooperation of a self-locking component and a stop hole, reliable anti-fall protection is formed throughout the lifting process, instantly locking and limiting the weight to reduce the probability of accidents. After lifting, the weight can be placed at the top of the shell, making full use of the unused space at the top of the shell and freeing up sufficient usable area at the bottom of the shell to place other items to be installed, thereby improving the overall utilization efficiency of the internal space of the shell.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0053] Example:
[0054] like Figures 1-5 The figure shown is a weight lifting structure for a heavy object provided in this embodiment, including a shell 1, a lifting slide 2, a fixing slide 3, and a self-locking component 4;
[0055] The lifting slide 2 is obliquely upwardly arranged on both sides inside the outer shell 1, and the weight 9 is installed inside the outer frame structure 12. The fixing slide 3 is fixed on both sides of the outer frame structure 12, and the inclination angle of the fixing slide 3 is the same as that of the lifting slide 2. The fixing slide 3 is provided with a stop hole 5. The lifting slide 2 is provided with multiple stop holes 5 along its extension direction. The fixing slide 3 is provided with a self-locking component 4. During the process of the fixing slide 3 on the outer frame structure 12 rising along the lifting slide 2, the self-locking component 4 can cooperate with the stop hole 5 to prevent the weight 9 from falling during the lifting process. When the weight 9 is lifted to a predetermined position at the top of the inner shell 1, it can be fixed inside the outer shell 1 by the fixing structure. Before the weight 9 is removed from the outer shell 1, the self-locking component 4 can be unlocked under the action of external force. During the lifting process, the heavy object 9 is driven by conventional mechanisms such as forklifts and electric push rods to rise to the predetermined position along the lifting slide 2 inside the outer shell 1. The lower space is released by lifting the heavy object 9. The lifting slide 2 and the fixed slide 3 added to realize the lifting function occupy less space than the top space of the outer shell 1 released after the heavy object 9 is lifted, thus realizing efficient utilization of the internal space of the outer shell 1.
[0056] During the upward movement of the fixed slide 3 along the lifting slide 2, the fixed slide 3 slides along the upper surface of the lifting slide 2. Under the action of gravity, the free section 413 of the self-locking pin 41 passes through the stop hole 5 on the fixed slide 3 and the stop hole 5 on the lifting slide 2 corresponding to the position of the stop hole 5 on the fixed slide 3. If the object 9 loses external force unexpectedly during the sliding and lifting process, it will slide down the lifting slide 2 under the action of gravity. Since the free section 413 of the self-locking pin 41 can be inserted into the stop hole 5 on the fixed slide 3 and the stop hole 5 on the lifting slide 2 at this time, the self-locking pin 41... 1. It can abut against the inner wall of the stop hole 5 to lock the heavy object 9 on the lifting slide 2, thereby preventing the heavy object 9 from slipping off the lifting slide 2 during the lifting process, avoiding damage to the heavy object 9 and threatening the life safety of the operator. At the same time, multiple stop holes 5 are set at intervals along the extension direction of the lifting slide 2, which can realize multi-level anti-falling locking of the heavy object 9 throughout the lifting process, covering the lifting path in all directions and eliminating the risk of the heavy object 9 falling accidentally. The fixed slide 3 has the same inclination angle as the lifting slide 2, which can ensure the stability of the fixed slide 3 when sliding along the lifting slide 2, further ensuring the safety of the lifting process.
[0057] In this embodiment, the fixed slide rail 3 is welded to both sides of the outer frame structure 12; the lifting slide rail 2 is welded to both sides inside the outer shell 1.
[0058] This utility model discloses a weight center lifting structure for heavy objects. By setting up a lifting slide 2 and a fixed slide 3, the weight center of the heavy object 9 can be lifted smoothly. Through the cooperation of the self-locking component 4 and the stop hole 5, a reliable anti-fall protection is formed to reduce the occurrence of accidents. After lifting, the top space of the outer shell 1 can be fully utilized, and other items to be installed can be placed at the bottom of the outer shell 1, improving the space utilization rate. Moreover, the overall structure adopts a welding and fixing method to ensure the connection strength between the lifting slide 2 and the outer shell 1, and between the fixed slide 3 and the heavy object 9, which can adapt to the lifting requirements of the heavy object 9. At the same time, the structure is simple, with few parts, which facilitates processing, manufacturing and subsequent maintenance, reducing production and maintenance costs.
[0059] In a specific embodiment, the self-locking component 4 includes a self-locking pin 41, a fixing base 42, and a baffle 43; the self-locking pin 41 includes an integrally formed connecting section 411, a transition section 412, and a free section 413;
[0060] The fixing seat 42 is welded to the upper surface of the fixing slide 3, and the fixing seat 42 is provided with a through hole 421, such as... Figures 1-4 as well as Figures 8-9 As shown, the through hole 421 is provided along the width direction of the fixed slide 3, and the self-locking pin 41 is provided along the extension direction (length direction) of the fixed slide 3.
[0061] The free segment 413 extends downward at one end of the transition segment 412, and the angle between the free segment 413 and the transition segment 412 is an obtuse angle. This allows the free segment 413 to directly enter and pass through the fixed slide 3 and the stop hole 5 of the lifting slide 2 under the action of gravity. If the external force driving the lifting weight 9 suddenly disappears, the free segment 413 can abut against the inner wall of the stop hole 5, overcoming the gravity of the weight 9 and sliding down. At the same time, the setting of the direction of the free segment 413 and the angle between it and the transition segment 412 allows the free segment 413 of the self-locking pin 41 to move out of the stop hole 5 on the lifting slide 2 under the action of external force (oblique upward direction) and the lifting slide 2 during the lifting process, without affecting the lifting of the weight 9. After the self-locking pin 41 moves out of the stop hole 5, as the height of the fixed slide 3 increases, the stop hole of the fixed slide 3... After the stop hole 5 moves to align with the stop hole 5 located on the upper part of the lifting slide 2, the free section 413 of the self-locking pin 41 can pass through the fixed slide 3 and insert into the stop hole 5 of the lifting slide 2. During the lifting process of the weight 9, the self-locking pin 41 repeatedly inserts into the stop hole 5, moves out of the stop hole 5, enters the next stop hole 5 on the lifting slide 2, and moves out of the stop hole 5 again until the weight 9 is lifted to the preset position. After reaching the preset position, the self-locking pin 41 is located in the stop hole 5 of the lifting slide 2. The obtuse angle setting can prevent the free section 413 from getting stuck with the inner wall of the stop hole 5, ensuring that the free section 413 can smoothly insert into and disengage from the stop hole 5. At the same time, it makes the contact surface between the free section 413 and the inner wall of the stop hole 5 larger, the force is more even, improves the reliability of self-locking, and prevents the self-locking pin 41 from being deformed or damaged due to force concentration.
[0062] The connecting segment 411 is vertically fixed to the end of the transition segment 412 on the other side. The connecting segment 411 is rotatably disposed at the through hole 421 and can reciprocate along the axial direction of the through hole 421. The end of the connecting segment 411 extending out of the through hole 421 is fixed with the baffle 43. The rotational engagement between the connecting segment 411 and the through hole 421 enables the self-locking pin 41 to rotate at multiple angles, satisfying the action requirements of the free segment 413 to insert into and disengage from the stop hole 5. The reciprocating movement of the connecting segment 411 along the axial direction of the through hole 421 provides displacement space for the unlocking of the self-locking assembly 4, ensuring that the unlocking action can be completed smoothly. The baffle 43 can axially limit the connecting segment 411, preventing the connecting segment 411 from disengaging from the through hole 421 when it moves along the axial direction of the through hole 421, thus ensuring the structural integrity and operational stability of the self-locking assembly 4.
[0063] As the weight 9 and the fixed slide 3 rise along the lifting slide 2, under the gravity of the self-locking pin 41, the connecting section 411 of the self-locking pin 41 can rotate around the through hole 421, causing the free section 413 to fall into the stop hole 5 of the fixed slide 3 and the lifting slide 2. As the external force continuously drives the weight 9 to rise, the free section 413 can disengage from the stop hole 5 located at the lower part of the lifting slide 2 and enter the stop hole 5 located at the upper part of the lifting slide 2 until the weight 9 is raised to the predetermined position. When the free section 413 of the self-locking pin 41 extends into (inserts) the stop hole 5 on the lifting slide 2, it can reliably lock and limit the weight 9, preventing the weight 9 from sliding down the lifting slide 2. The self-locking action is completed by the gravity of the self-locking pin 41 itself, without the need for additional power, simplifying the structural design. At the same time, it realizes the automation of the self-locking action, reduces the operation steps of the operator, improves the operation efficiency, and avoids the failure of the fall protection due to human operation error.
[0064] When the heavy object 9 needs to be removed from the outer casing 1, external force can drive the connecting section 411 to rotate within the through hole 421, causing the free section 413 to move out of the stop hole 5. The connecting section 411, under the action of external force, can continue to move axially along the through hole 421 to the unlocked position and can be fixed to the fixing seat 42 by the fixing member 6. Figures 6-7 The diagram shows the self-locking pin 41 in the unlocked position. The unlocking process can be completed simply by driving the connecting section 411 to rotate and move axially through external force and by fixing the connecting section 411 to the fixed seat 42. No complicated tools are needed, which reduces the difficulty of unlocking operation. The fixed cooperation between the fixing part 6 and the fixed seat 42 can stably lock the self-locking component 4 in the unlocked position, preventing the self-locking pin 41 from being inserted into the stop hole 5 again due to gravity or vibration during the disassembly of the heavy object 9, which would prevent the heavy object 9 from sliding down smoothly, thus ensuring the smoothness and safety of the disassembly process.
[0065] In a specific embodiment, a fixing groove 422 is provided on the fixing base 42 along the axial direction of the through hole 421. The connecting section 411 can rotate and move axially into the fixing groove 422 under the drive of external force, that is, it is in the unlocked position.
[0066] Both the connecting section 411 and the fixing groove 422 are provided with tapered insertion holes 44; the fixing member 6 is a tapered insertion rod, which can be inserted into the tapered insertion holes 44 on both the connecting section 411 and the fixing groove 422 simultaneously, fixing the connecting section 411 to the fixing base 42. This allows the self-locking member to be rotated upwards around the fixing base 42, causing its free section 413 to move out of the stop hole 5. Then, the self-locking member is pushed axially along the through hole 421, causing the connecting section 411 of the self-locking member to enter the fixing groove 422 and be firmly fixed by the tapered insertion rod. To prevent the free section 413 of the self-locking pin 41 from re-inserting into the stop hole 5 during the downward movement of the weight 9 along the lifting slide 2, thus affecting the unloading of the weight 9, the fixing groove 422 can position the connecting section 411, ensuring that the connecting section 411 can move accurately to the unlocking position, and preventing the connecting section 411 from shifting and causing the fixing part 6 to be unable to be inserted; the cooperation between the tapered insertion hole 44 and the tapered insertion rod, utilizing the self-locking characteristics of the tapered surface, can achieve a firm fixation between the connecting section 411 and the fixing seat 42. At the same time, the tapered structure facilitates the insertion and removal of the insertion rod, improving the convenience and smoothness of the unlocking and fixing operations.
[0067] In a specific embodiment, the fixed slide 3 includes a horizontal plate 31 and a vertical plate 32 disposed at one end of the horizontal plate 31 in a vertical direction, and the stop hole 5 is disposed on the horizontal plate 31.
[0068] The lifting slide 2 includes a horizontal plate 21 and a vertical plate 22 located at one end of the horizontal plate 21. The stop hole 5 is located on the horizontal plate 21, and the vertical plate 22 is welded and fixed to the outer shell 1. When the load 9 is lifted, the bottom surface of the horizontal plate 31 contacts the upper surface of the horizontal plate 21 and slides along the horizontal plate 21, while the side wall of the vertical plate 32 is in contact with the side wall of the horizontal plate 21. The horizontal plate 31 and the horizontal plate 21 adopt a surface contact sliding cooperation form, which increases the sliding contact area, makes the force distribution more uniform when the load 9 is lifted, and ensures that the lifting process of the center of gravity of the load 9 is smooth and stable. The horizontal plate 21 provides a stable sliding support surface for the fixed slide 3, ensuring the stability of the lifting of the center of gravity of the load 9. The vertical plate 32 and the side wall of the horizontal plate 21 are in close contact, which can form a reliable lateral limit for the fixed slide rail 3, preventing the fixed slide rail 3 from shifting left or right along the sliding direction, and further improving the positional stability and operational safety of the lifting object 9 during the lifting process; the vertical plate 22 is used to weld and fix it to the outer shell 1, which enhances the overall installation firmness of the lifting slide rail 2. At the same time, the vertical plate 22 and the horizontal plate 21 form an L-shaped lifting slide rail 2, which enhances the structural strength of the lifting slide rail 2 itself and extends its service life; both the fixed slide rail 3 and the lifting slide rail 2 adopt sheet metal welding structure, which is simple in structure, convenient to process, and has high overall structural strength, which can meet the long-term reciprocating lifting needs of the heavy object 9.
[0069] In a specific embodiment, the fixing structure is a commonly used detachable or non-detachable fixing method in the art, including but not limited to threaded connection, snap-fit connection, plug-in fit, and riveting; in this embodiment, the fixing structure includes fixing ears 7 and fixing plates 8; the fixing ears 7 are welded and fixed to both sides of the outer frame structure 12; the fixing plates 8 are welded and fixed to both sides inside the outer shell 1, and the fixing ears 7 and fixing plates 8 can be fixed by bolts; the cooperation of fixing ears 7 and fixing plates 8 can firmly fix the outer frame structure 12 raised to the preset position inside the outer shell 1, preventing the outer frame structure 12 and its weight from being lifted into place. The object 9 shakes and slides inside the outer shell 1, ensuring the stability of the installation of the object 9 and preventing damage to parts or safety accidents caused by the shaking of the outer frame structure 12. The bolt connection is detachable, which facilitates the maintenance, repair or disassembly of the outer frame structure 12 and the object 9 inside the outer frame structure 12 in the later stage. At the same time, the bolt connection is strong and can withstand the weight of the outer frame structure 12 and the object 9, preventing the connection from loosening. The fixing lug 7 is fixed to the outer frame structure 12 and the fixing plate 8 is fixed to the outer shell 1 by welding, which ensures the connection strength, further improves the reliability of the fixing structure, and adapts to the fixing requirements of the object 9.
[0070] In a specific embodiment, the stop hole 5 is an elongated hole opened along the extension direction of the fixed slide 3 and the lifting slide 2, so that the self-locking pin 41 can disengage from the stop hole 5 when unlocking is required. The stop hole 5 opened along the extension direction can match the movement trajectory of the free segment 413 of the self-locking pin 41, ensuring smooth insertion and disengagement of the free segment 413. At the same time, the opening direction of the stop hole 5 is consistent with the extension direction of the fixed slide 3 and the lifting slide 2, which can accurately limit the movement trajectory of the heavy object 9, prevent the heavy object 9 from deviating when moving, and cooperate with the self-locking pin 41 to achieve anti-falling limit, ensuring the safety of the heavy object 9 throughout the lifting process. At the same time, the cooperation between the stop hole 5 and the self-locking pin 41 can limit the movement range of the heavy object 9 to within the stop hole 5 during the lifting process, realize anti-falling during the lifting process of the heavy object 9, and ensure the safety of the lifting of the heavy object 9.
[0071] In a specific embodiment, the outer shell 1 is provided with an operation window 10 for unlocking the self-locking pin 41. Before disassembly, the self-locking pin 41 can be unlocked from outside the operation window 10 without entering the inner shell 1, thus avoiding collisions between the operator and components such as the heavy object 9 and the lifting slide 2, reducing safety hazards. In addition, the operation window 10 also makes it easy for the operator to observe the unlocking status of the self-locking pin 41, ensuring that the unlocking operation is in place and avoiding the heavy object 9 being unable to be disassembled smoothly due to incomplete unlocking.
[0072] In a specific embodiment, a handle 11 is welded onto the outer frame structure 12 to provide a stable point of force for the operator, making it easier for manual assistance to push and pull the heavy object 9 along the lifting slide 2, reducing manpower consumption. At the same time, the handle 11 can prevent the operator from directly contacting the surface of the heavy object 9, improving the safety and convenience of operation.
[0073] In a specific embodiment, such as Figures 10-14 As shown, the outer frame structure 12 includes a frame body 121 and a plate 122 installed on the outside of the frame body 121. The frame body 121 is a rectangular hollow structure formed by welding multiple horizontal beams 121a and multiple vertical beams 121b. The interior of the frame body 121 is used to accommodate the weight 9. The two sides of the frame body 121 are provided with inclined beams 123 at the same angle as the fixed slide rail 3. The vertical plate 32 of the fixed slide rail 3 is welded and fixed to the outside of the inclined beams 123. The inclined beams 123 provide a mounting base for the fixed slide rail 3 and ensure connection strength. In this embodiment, the plate 122 is a metal plate. The plate 122 is fixed to the outside of the frame body 121 by bolts to enclose the frame body 121, ensuring safety and aesthetics. The plate 122 does not cover the inclined beams 123 or the area where the handle 11 is located. If the weight 9 is a battery pack, once the battery cells of the battery pack experience thermal runaway and violently eject high-temperature gas, using a metal plate of a certain thickness to cover it can delay the spread of heat to surrounding equipment, buying more time for fire fighting and rescue. The outer frame structure 12 as a whole must meet the installation strength requirements of the fixed slide rail 3, as well as the support strength requirements for the weight 9 during the lifting process.
