Description

Technical Field

[0001] This utility model generally relates to the field of logistics and transportation technology, and more specifically, to a loader. Background Technology

[0002] With the rapid development of air freight, container loaders need to dock with the aircraft cabin to transport goods during loading and unloading operations.

[0003] Currently, existing containerized cargo loaders consist of forks and a platform. One end of the platform is fixed to the forks, while the other end is engaged with rollers that roll along the platform's grooves. With this method, if the weight of the cargo on the platform changes significantly, the rollers will roll along the platform's grooves, causing the forks to deform. This results in changes in the platform's height, leading to platform subsidence or elevation, affecting cargo transport, and potentially causing collision damage to aircraft, thus posing a relatively low safety risk. Utility Model Content

[0004] The loader provided by this utility model can reduce the deformation of the lifting platform during the transportation process.

[0005] According to a first aspect of the present invention, a loader is provided, comprising:

[0006] A lifting platform is used to carry items to be transported.

[0007] A lifting mechanism is connected to the lifting platform, and the lifting mechanism is configured to move relative to the lifting platform in a first direction, so that the lifting platform can move up and down in a second direction.

[0008] An anti-settlement structure is disposed between the lifting platform and the lifting mechanism. The anti-settlement structure is configured to switch the lifting mechanism and the lifting platform between a locking mode and an unlocking mode when the lifting mechanism moves relative to the lifting platform in the first direction.

[0009] The first direction and the second direction are perpendicular to each other.

[0010] In some embodiments, the anti-settlement structure includes:

[0011] A rack is disposed on the lifting platform and extends along the first direction;

[0012] A locking gear is rotatably connected to the lifting mechanism, and the locking gear meshes with the rack;

[0013] A locking component is disposed on the lifting mechanism, and the locking component can selectively abut against the locking gear.

[0014] In some embodiments, the locking component includes:

[0015] Locking element;

[0016] A locking drive source is provided in the lifting mechanism, and the output end of the locking drive source is connected to the locking member;

[0017] The locking drive source can drive the locking member to move towards the locking gear, so that the locking member abuts against the locking gear, for the lifting mechanism and the lifting platform to be in the locking mode; the locking drive source can also drive the locking member to move away from the locking gear, so that the locking member disengages from the locking gear, for the lifting mechanism and the lifting platform to be in the unlocking mode.

[0018] In some embodiments, the locking gear has a plurality of teeth arranged circumferentially along the locking gear;

[0019] The locking member has a pointed structure at one end facing the locking gear. The pointed structure can be located between two adjacent teeth and can abut against the tooth surfaces of the two adjacent teeth that are close to each other.

[0020] In some embodiments, the locking component further includes:

[0021] A guide member is disposed in the lifting mechanism and located between the locking drive source and the locking gear. The guide member is provided with a guide hole, and the locking member passes through the guide hole and slides in cooperation with the guide hole.

[0022] In some embodiments, the locking component further includes:

[0023] An installation component is provided on the lifting mechanism, and the end of the locking drive source away from the locking component is provided with an installation hole, through which the installation component passes;

[0024] A fixing member is disposed on the side of the mounting member along the second direction and away from the lifting mechanism, and the fixing member abuts against the locking drive source.

[0025] In some implementations, it also includes:

[0026] A signal generator is used to send a lifting signal to the lifting platform;

[0027] A first sensor is disposed on the lifting mechanism for detecting the first extreme position of the locking member in the unlocking mode.

[0028] A second sensor is disposed on the lifting mechanism for detecting the second extreme position of the locking member in the locking mode.

[0029] In some embodiments, the locking component further includes:

[0030] A support shaft is disposed at one end of the lifting mechanism along the second direction and facing the rack;

[0031] The bearing is sleeved on the outside of the support shaft and located between the support shaft and the locking gear.

[0032] In some implementations, it also includes:

[0033] The third sensor, located on one side of the lifting platform, is used to detect the amount of deformation of the lifting platform relative to the horizontal plane when it is carrying the item to be transported.

[0034] In some embodiments, the lifting mechanism includes two links that are rotatably connected to each other and arranged in a cross configuration to form an X-shaped structure. At least one of the links is connected to the lifting platform at one end facing the lifting platform via the anti-settlement structure.

[0035] One embodiment of this utility model has the following advantages or beneficial effects:

[0036] The loader provided in this embodiment, when the lifting platform needs to transport the workpiece, uses an anti-settlement structure to lock the lifting mechanism and the lifting platform in a locked mode, forming a stable triangular structure between the two connecting rods of the lifting platform and the lifting mechanism, thus preventing the lifting platform from settling when the lifting mechanism moves relative to the lifting platform in the first direction. When the lifting platform needs to be raised or lowered, the anti-settlement structure locks the lifting mechanism and the lifting platform in an unlocked mode, allowing the lifting mechanism to drive the lifting platform to move up and down in the second direction through the anti-settlement structure.

[0037] By setting an anti-settlement structure between the lifting mechanism and the lifting platform, the lifting mechanism and the lifting platform can switch between locked and unlocked modes when the lifting mechanism moves relative to the lifting platform in the first direction. This does not affect the lifting function of the lifting mechanism driving the lifting platform. Furthermore, when lifting is required, it can prevent the lifting mechanism from deforming due to a large change in the weight of the item to be transported, thus avoiding changes in the height of the lifting platform. This achieves the purpose of preventing the lifting platform from settling. Attached Figure Description

[0053] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0054] This embodiment provides a loader, such as Figure 1As shown, the loader includes a lifting platform 1 and a lifting mechanism 2. The lifting platform 1 is used to carry the parts to be transported. The lifting mechanism 2 is connected to the lifting platform 1 and is configured to move relative to the lifting platform 1 in a first direction, causing the lifting platform 1 to move up and down in a second direction.

[0055] For example, the included angle between the first direction and the second direction can be an acute angle or a right angle. Specifically, the lifting platform 1 has at least one horizontal plane, the second direction is perpendicular to the horizontal plane, and the first direction and the third direction are two mutually perpendicular directions within the horizontal plane. The first direction is identified by D1, and the second direction is identified by D2. The first direction is parallel to the long side direction of the lifting platform 1, and the third direction is parallel to the short side direction of the lifting platform 1. The third direction is identified by D3, and the first direction, the second direction, and the third direction are mutually perpendicular to each other. In this embodiment, the first direction is a horizontal direction and the second direction is a vertical direction as an example.

[0056] For example, the lifting mechanism 2 can be directly connected to the lifting platform 1, or it can be indirectly connected to the lifting platform 1. Furthermore, the lifting mechanism 2 can move simultaneously along a first direction and a second direction. When the lifting mechanism 2 moves along the second direction, it can drive the lifting platform 1 to move synchronously along the second direction. Alternatively, the lifting mechanism 2 can not move along either the first or second direction, but rather tilt along a direction that forms a certain angle with both the first and second directions. In this case, the force of the lifting mechanism 2 can be decomposed into a first force along the first direction and a second force along the second direction, using the second force to drive the lifting platform 1 to move along the second direction.

[0057] Specifically, such as Figure 1 As shown, the lifting mechanism 2 includes two connecting rods 21, which are rotatably connected to each other and arranged in a cross configuration. That is, the two connecting rods 21 are rotatably connected at approximately the middle position via a pivot 22, forming an X-shaped structure. At least one end of the two connecting rods 21 facing the lifting platform 1 is connected to the lifting platform 1.

[0058] When the two links 21 move along the first direction and toward each other, that is, when the two links 21 are in a gradually closed state, the height of the links 21 along the second direction increases, so as to drive the lifting platform 1 to move upward along the second direction; when the two links 21 move along the first direction and toward each other, that is, when the two links 21 are in a gradually open state, the height of the links 21 along the second direction decreases, so as to drive the lifting platform 1 to move downward along the second direction.

[0059] If one of the connecting rod 21 and the lifting platform 1 is equipped with a support wheel, and the other with a sliding groove, the support wheel can roll freely relative to the sliding groove without affecting the opening and closing of the two connecting rods 21. However, after the lifting platform 1 reaches the preset position, the connecting rod 21 and the lifting platform 1 cannot lock together, meaning the support wheel and the lifting platform 1 cannot form a locked connection, resulting in the lifting platform 1 and the two connecting rods 21 not forming a stable triangular structure. At this time, when a transported item is suddenly loaded onto the lifting platform 1, the end of the connecting rod 21 in the lifting mechanism 2 will form a cantilever beam structure due to gravity, causing deformation. This will cause the support wheel to slide to the left along the first direction, resulting in a decrease in the left side height of the lifting platform 1 and causing the lifting platform 1 to sink. When a transported item is suddenly unloaded from the lifting platform 1, the end of the connecting rod 21 in the lifting mechanism 2 will experience a sudden reduction in gravity, reducing the deformation of the cantilever beam structure. The support wheel will slide to the right along the first direction, causing the left side height of the lifting platform 1 to rise, resulting in an increase in the lifting platform 1.

[0060] To solve this problem, such as Figures 1-2 As shown, the loader provided in this embodiment also includes an anti-settlement structure 3, which is disposed between the lifting platform 1 and the lifting mechanism 2. The anti-settlement structure 3 is configured to switch the lifting mechanism 2 and the lifting platform 1 between a locking mode and an unlocking mode when the lifting mechanism 2 moves relative to the lifting platform 1 in a first direction.

[0061] Specifically, the anti-settlement structure 3 can be installed on the loader's bridge platform or front platform, or on the rear platform.

[0062] Specifically, at least one end of the two connecting rods 21 in the lifting mechanism 2 facing the lifting platform 1 is connected to the lifting platform 1 via an anti-settlement structure 3. For example, one of the two connecting rods 21 at its top along the second direction is connected to the lifting platform 1 via the anti-settlement structure 3, and the other is rotatably connected to the lifting platform 1 via a connecting shaft. Alternatively, both connecting rods 21 at their tops along the second direction can be connected to the lifting platform 1 via the anti-settlement structure 3.

[0063] When the lifting platform 1 needs to transport items, the anti-settlement structure 3 locks the lifting mechanism 2 and the lifting platform 1 in a locked state, forming a stable triangular structure between the two connecting rods 21 of the lifting platform 1 and the lifting mechanism 2. This prevents the lifting platform 1 from settling when the lifting mechanism 2 moves relative to the lifting platform 1 in the first direction. When the lifting platform 1 needs to be raised or lowered, the anti-settlement structure 3 unlocks the lifting mechanism 2 and the lifting platform 1, allowing the lifting mechanism 2 to drive the lifting platform 1 to move in the second direction via the anti-settlement structure 3.

[0064] The loader provided in this embodiment, by setting an anti-settlement structure 3 between the lifting mechanism 2 and the lifting platform 1, allows the lifting mechanism 2 and the lifting platform 1 to switch between locked and unlocked modes when the lifting mechanism 2 moves relative to the lifting platform 1 in the first direction. This does not affect the lifting function of the lifting mechanism 2 driving the lifting platform 1. Furthermore, when lifting is required, it can also prevent the lifting mechanism 2 from deforming due to a large change in the weight of the item to be transported, which would ultimately cause a change in the height of the lifting platform 1, thereby achieving the purpose of preventing the lifting platform 1 from settling.

[0065] In one embodiment, such as Figures 2-3 As shown, the anti-settlement structure 3 includes a rack 31, a locking gear 32, and a locking component 33. The rack 31 is disposed on the lifting platform 1 and extends along the first direction. The locking gear 32 is rotatably connected to the lifting mechanism 2 and meshes with the rack 31. The locking component 33 is disposed on the lifting mechanism 2 and can selectively abut against the locking gear 32.

[0066] For example, when the lifting platform 1 needs to transport a component, the locking component 33 abuts against the locking gear 32, preventing the locking gear 32 from meshing with the rack 31 and allowing it to roll relative to the rack 31, forming a rigid and stable structure. Even if the weight of the component to be transported on the lifting platform 1 changes, the height of the lifting platform 1 along the second direction will not change because the locking gear 32 is limited to a fixed position on the rack 31. When the lifting platform 1 needs to transport a component, the locking component 33 does not abut against the locking gear 32. When the two connecting rods 21 of the lifting mechanism 2 move closer or further apart from each other along the first direction, the locking gear 32 meshes with the rack 31 and can roll relative to the rack 31. Since the rack 31 extends along the first direction, it will not affect the movement of the lifting mechanism 2 along the first direction, ensuring that the lifting mechanism 2 achieves its lifting function.

[0067] In one embodiment, such as Figures 2-3 As shown, the locking assembly 33 also includes a support shaft 34, which is disposed at one end of the lifting mechanism 2 along the second direction and toward the rack 31. Exemplarily, the support shaft 34 extends along a third direction, the bottom of the support shaft 34 is welded to the connecting rod 21 of the lifting mechanism 2, and the top of the support shaft 34 passes through a locking gear 32, which can rotate around the support shaft 34.

[0068] In one embodiment, the locking assembly 33 further includes a bearing (not shown) that is sleeved outside the support shaft 34 and located between the support shaft 34 and the locking gear 32, thereby ensuring the smooth rotation of the locking gear 32 relative to the support shaft 34.

[0069] In one embodiment, such as Figures 2-3As shown, the locking assembly 33 includes a locking element 331 and a locking drive source 332. The locking drive source 332 can be a motor, cylinder, hydraulic cylinder, electric cylinder, etc. The locking drive source 332 is mounted on the connecting rod 21 of the lifting mechanism 2 and can be fixed to the connecting rod 21 by welding, bolts, or other connecting parts. The output end of the locking drive source 332 is connected to the locking element 331. For example, the locking element 331 can be the output shaft of the locking drive source 332, and the shape of the locking element 331 can be cylindrical, cuboid, etc.

[0070] When the lifting mechanism 2 and the lifting platform 1 need to be in a locked mode, the locking drive source 332 can drive the locking member 331 to move towards the locking gear 32, so that the locking member 331 abuts against the locking gear 32, and the locking gear 32 is fixed in position relative to the rack 31; when the lifting mechanism 2 and the lifting platform 1 need to be in an unlocked mode, the locking drive source 332 can drive the locking member 331 to move away from the locking gear 32, so that the locking member 331 disengages from the locking gear 32, and the locking gear 32 can mesh with the rack 31 and roll relative to the rack 31.

[0071] Specifically, the locking gear 32 has a plurality of teeth arranged circumferentially along the locking gear 32, and the teeth mesh with the rack 31. The locking member 331 has a tip structure 3311 (e.g., ...) at one end facing the locking gear 32. Figure 4 As shown, the tip structure 3311 can be located between two adjacent teeth and can abut against the tooth surfaces of the two adjacent teeth that are close to each other. Exemplarily, the locking member 331 has two inclined surfaces symmetrically arranged on the peripheral sidewall of the end facing the locking gear 32 to form the tip portion.

[0072] By providing a pointed structure 3311 at the end of the locking member 331, the cross-section of the pointed structure 3311 is smaller than that of the locking member 331. From the direction away from the locking member 331, the cross-section of the pointed structure 3311 gradually decreases, forming a wedge-shaped structure. Because the gap between two adjacent teeth is relatively small, the pointed structure 3311 can extend into the gap between the two adjacent teeth. Simultaneously, the pointed structure 3311 can abut against the tooth surfaces of two adjacent teeth, locking two adjacent teeth with one pointed structure 3311, ensuring the stability of the locking.

[0073] In one embodiment, such as Figures 2-4As shown, the locking assembly 33 also includes a guide member 333. Exemplarily, the guide member 333 may be a guide plate, which has a cuboid structure. The guide member 333 is disposed on the connecting rod 21 of the lifting mechanism 2 and located between the locking drive source 332 and the locking gear 32. The guide member 333 has a guide hole, through which the locking member 331 passes and slides. The guide hole of the guide member 333 guides the locking member 331, limiting its movement direction and preventing significant positional deviation. Simultaneously, since the locking member 331 is located at the output end of the locking drive source 332, the guide member 333 can also effectively correct and reset the locking drive source 332 to a certain extent.

[0074] In one embodiment, such as Figures 2-4 As shown, the locking assembly 33 also includes a mounting member 334 and a fixing member 335. The mounting member 334 is disposed on the lifting mechanism 2. The locking drive source 332 has a mounting hole 3321 at its end away from the locking member 331, and the mounting member 334 passes through the mounting hole 3321. The fixing member 335 is disposed on the side of the mounting member 334 along the second direction and away from the lifting mechanism 2, and the fixing member 335 abuts against the locking drive source 332.

[0075] For example, the mounting member 334 may be a mounting shaft, with its bottom welded to the connecting rod 21 and its top passing through the mounting hole 3321 of the locking drive source 332. The fixing member 335 may be a cotter pin or an annular structure, fitted onto the end of the mounting shaft and abutting against the locking drive source 332 to prevent the locking drive source 332 from detaching from the mounting member 334, and the fixing member 335 serves as a limiting element.

[0076] In some other embodiments, the fixing member 335 may also be a fixing pin, which includes a vertical portion and a horizontal portion. The vertical portion and the horizontal portion are perpendicular to each other and form an L-shaped structure. The vertical portion of the fixing member 335 is inserted from the top of the mounting member 334, and the horizontal portion of the fixing member 335 abuts against the locking drive source 332, thereby fixing the locking drive source 332. Of course, the fixing and installation of the locking drive source 332 provided in this embodiment includes, but is not limited to, the above two forms. Other fixing methods may also be selected, as long as the installation and fixing of the locking drive source 332 can be achieved, they are all within the protection scope of this embodiment.

[0077] In one embodiment, such as Figure 5As shown, the loader also includes a signal generator 4, a first sensor 5, and a second sensor 6. The signal generator 4 is used to send a lifting signal for the lifting platform 1. The first sensor 5 is disposed on the lifting mechanism 2 and is used to detect the first limit position of the locking member 331 in the unlocking mode. The second sensor 6 is disposed on the lifting mechanism 2 and is used to detect the second limit position of the locking member 331 in the locking mode.

[0078] For example, the signal generator 4 can be located outside the lifting mechanism 2, such as in the control room of the loader. When the operator triggers the lifting or stopping button of the lifting platform 1, the signal generator 4 can promptly identify the lifting signal of the lifting platform 1.

[0079] For example, both the first sensor 5 and the second sensor 6 can be infrared sensors. Both sensors can be set on the connecting rod 21. The first sensor 5 can be set on the side of the locking drive source 332 away from the locking gear 32, and is used to detect the first limit position of the locking member 331 in the unlocking mode to determine whether the locking member 331 has retracted into place. The second sensor 6 can be set on the side of the locking drive source 332 facing the locking gear 32, and is used to detect the second limit position of the locking member 331 in the locking mode to determine whether the locking member 331 has extended into place.

[0080] Specifically, such as Figure 5 As shown, the loader also includes a controller 7, which can be a PLC control unit. The controller 7 is electrically connected to the signal generator 4, the first sensor 5, and the second sensor 6. The controller 7 can communicate with the vehicle control system to obtain platform operation commands and operating status. The controller 7 can be directly electrically connected to the locking drive source 332, or indirectly connected to the locking drive source 332 via the power module 9, to control the extension and retraction of the locking drive source 332. The power module 9 can be powered by a prime mover or an electric motor, providing actuation power to the locking cylinder.

[0081] When signal generator 4 detects the lifting signal of lifting platform 1, it transmits the signal to controller 7. Controller 7 sends a command to power module 9 via line or CAN instruction. Upon receiving the command, power module 9 controls locking drive source 332 to perform a retraction action. During the retraction process of locking member 331 driven by locking drive source 332, if locking member 331 triggers first sensor 5, the first sensor 5 detects the position of locking member 331, indicating that locking member 331 is at its first limit position, i.e., in a fully retracted state, and locking gear 32 can freely roll along rack 31. First sensor 5 transmits this position signal to controller 7, and controller 7 controls lifting mechanism 2 to operate, driving lifting platform 1 to perform lifting motion.

[0082] When the signal generator 4 detects the disappearance of the lifting signal of the lifting platform 1, the signal generator 4 transmits the signal to the controller 7. The controller 7 sends a command to the power module 9 via line or CAN instruction. Upon receiving the command, the power module 9 controls the locking drive source 332 to perform the extension action. The locking drive source 332 drives the locking member 331 to extend and abut against the locking gear 32. The locking gear 32 and the rack 31 are in a locked state. The locking gear 32 cannot rotate, and the locking gear 32 and the rack 31 are fully meshed. At this time, the lifting platform 1 and the two connecting rods 21 form a stable triangular structure. Even if the weight of the item to be transported on the lifting platform 1 changes, it will not cause the connecting rods 21 to deform.

[0083] Using this method, the settlement of the elevator platform 1 can be reduced to 1 / 20 of the original, or even less. Such a small settlement provides good protection for the aircraft, that is, the transported items or the elevator platform 1 will not collide with the aircraft due to excessive settlement of the platform, which greatly reduces or eliminates the risk of collision with the aircraft.

[0084] In one embodiment, such as Figure 5 As shown, the loader also includes a third sensor 8, which is located on one side of the lifting platform 1 and is used to detect the amount of deformation of the lifting platform 1 relative to the horizontal plane when it is carrying the object to be transported.

[0085] For example, the third sensor 8 may be an infrared sensor, and the third sensor 8 may be mounted on the base of the lifting mechanism 2. The third sensor 8 may also be referred to as a ground measurement sensor.

[0086] For example, during the process of the lifting platform 1 transporting the item to be transported, the amount of deformation of the lifting platform 1 relative to the horizontal plane can be the amount of settlement or rebound of the lifting platform 1.

[0087] Specifically, when the lifting platform 1 is transporting the item to be transported, the third sensor 8 detects the actual deformation of the lifting platform 1. If the actual deformation is less than the preset deformation, it means that the anti-settlement structure 3 is in normal operation. If the actual deformation is greater than or equal to the preset deformation, it means that the anti-settlement structure 3 is out of reasonable range. It can be considered that the anti-settlement structure 3 has malfunctioned, or that the mechanical structure has serious deformation, or that the structural components have cracked, etc., prompting the operator to pay attention to maintenance.

[0088] In another embodiment, the loader may also be equipped with a storage medium for storing data such as the lifting signal of the signal generator 4, the retraction signal of the first sensor 5, the extension signal of the second sensor 6, and the deformation detected by the third sensor 8 during cargo transportation. When the anti-settlement structure 3 malfunctions, the fault data can be traced for easy fault analysis.

[0089] It should be noted that the embodiments of this utility model are merely one example of the principles employed by the present utility model, as shown in the accompanying drawings and described herein. Those skilled in the art will clearly understand that the principles of this utility model are not limited to any details or components of the apparatus shown in the accompanying drawings or described in the specification.
