Description

Technical Field

[0001] This application relates to the field of logistics equipment technology, and in particular to a locking device and a cage-turning loading and unloading equipment. Background Technology

[0002] In related technologies, locking devices are installed on equipment to prevent items from falling out. For example, after a cage cart is loaded into a cage-unloading device, it will rotate counterclockwise within a range of 0-150° to unload the packages inside, allowing them to be transferred to other conveying equipment. During the cage cart rotation process, there is a risk of the cage cart running out of the equipment or colliding with it and generating noise. To avoid these situations, the position of the cage cart inside the equipment needs to be locked. Summary of the Invention

Detailed Implementation

[0034] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, 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.

[0035] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] See Figures 1 to 12As shown, this embodiment provides a locking device for restricting the movement of a target workpiece. The locking device includes a stop 101, an adjusting part 102, and a locking mechanism. The stop 101 is connected to the adjusting part 102. The locking mechanism has an unlocked state and a locked state. The locking mechanism is configured such that, in the unlocked state, the adjusting part 102 can move relative to the locking mechanism to adjust the position of the stop 101 relative to the target workpiece. The locking mechanism is also configured such that, in the locked state, the adjusting part 102 can be fixed relative to the locking mechanism to fix the position of the stop 101 relative to the target workpiece and restrict the movement of the target workpiece.

[0038] Based on this structure, the locking device provided in this embodiment can conveniently and quickly adjust the position of the stop part 101 relative to the target workpiece by sliding the adjustment part 102 relative to the locking mechanism in the unlocked state, and then make the locking mechanism in the locked state. At this time, the adjustment part 102 can be fixed relative to the locking mechanism, thereby fixing the position of the stop part 101 relative to the target workpiece and ensuring that the stop part 101 can restrict the movement of the target workpiece.

[0039] It should be noted that the target workpiece can be a cage car, cargo, or other equipment, parts, and items that need to be stopped.

[0040] In this embodiment, the locking device is described in detail using a cage car as an example of the target workpiece.

[0041] When locking the cage car 300, the stop part 101 needs to abut against the top of the cage car 300 to prevent the cage car 300 from easily rushing out of the equipment during the overturning process of the cage loading and unloading equipment. Since the cage car 300 has various specifications and sizes, the locking device needs to be adjustable to accommodate cage cars 300 of different heights. The locking device provided in this embodiment allows the adjusting part 102 to slide relative to the locking mechanism in the unlocked state, which can conveniently and quickly adjust the position of the stop part 101, so that the stop part 101 abuts against the cage car 300, thereby realizing the rapid locking of cage cars of different heights.

[0042] It should be noted that when the target workpiece is other equipment or goods, the stop part 101 can also abut against other positions of the target workpiece, or the stop part 101 can also leave a certain distance between it and the target workpiece. Of course, the stop part 101 can also directly or indirectly contact the target workpiece through magnetic attraction, as long as the function of restricting the movement of the target workpiece can be achieved.

[0043] In one embodiment, the locking mechanism includes a first locking part 103, a second locking part 104, and a connecting part 105; both the first locking part 103 and the second locking part 104 are hinged to the connecting part 105; the first locking part 103 is provided with a first receiving groove 1031, and the second locking part 104 is provided with a second receiving groove 1041; in the locked state, the first locking part 103 and the second locking part 104 are engaged to fix the adjusting part 102 inside the first receiving groove 1031 and the second receiving groove 1041.

[0044] In the locked state, the first locking part 103 and the second locking part 104 engage, causing the openings of the first receiving groove 1031 and the second receiving groove 1041 to face each other, thereby fixing the adjusting part 102 within the receiving space formed by the first receiving groove 1031 and the second receiving groove 1041. In some embodiments, the adjusting part 102 and the groove walls of the first receiving groove 1031 and the second receiving groove 1041 can be fixed together by magnetic attraction, thereby restricting the movement of the adjusting part 102. For example, the outer surface of the adjusting part 102 is provided with a first magnetic element, and the groove walls of the first receiving groove 1031 and the second receiving groove 1041 are provided with second magnetic elements, which attract each other. For example, the first magnetic element and the second magnetic element are mutually attracting magnets, or one of the first magnetic element and the second magnetic element is an ferrous metal, and the other is a magnet. Of course, the material of the adjusting part 102 can also be an ferrous metal, and the material of the first locking part 103 and the second locking part 104 can be a magnet.

[0045] In one embodiment, see Figure 3 As shown, the first locking part 103 is hinged to one end of the connecting part 105, and the second locking part 104 is hinged to the other end of the connecting part 105. The connecting part 105 is provided with a through hole 1051. The adjusting part 102 passes through the through hole 1051 and can slide relative to the connecting part 105 to adjust the position of the stop part 101 relative to the target workpiece.

[0046] For example, see Figure 4 As shown, the connecting part 105 has a rectangular block structure. The first locking part 103 is hinged to one end of the connecting part 105 through the first hinge shaft 106, and the second locking part 104 is hinged to the other end of the connecting part 105 through the second hinge shaft 107. In the locked state, the receiving space formed by the first receiving groove 1031 and the second receiving groove 1041 is aligned with and connected to the through hole 1051, so that the adjusting part 102 passes through the through hole 1051 and the receiving space. In the unlocked state, the first locking part 103 and the second locking part 104 release the restriction on the adjusting part 102, so that the adjusting part 102 can slide relative to the connecting part 105 to adjust the position of the stop part 101 according to the height of the cage car 300, so that the stop part 101 abuts against the top of the cage car 300.

[0047] It should be noted that the first locking part 103 and the second locking part 104 can also be hinged to the connecting part 105 via the same hinge axis.

[0048] In one embodiment, the adjusting part 102 is rod-shaped, and a limiting part is provided on the circumferential surface of the adjusting part 102. The groove wall of the first receiving groove 1031 and the groove wall of the second receiving groove 1041 are both provided with limiting mating parts. In the locked state, the limiting mating parts cooperate with the limiting parts to fix the adjusting part 102 inside the first receiving groove 1031 and the second receiving groove 1041.

[0049] For example, the adjusting part 102 is in the shape of a round rod, which facilitates its movement and adjustment and avoids the limitations imposed by sharp edges. See also Figure 6 As shown, both the first receiving groove 1031 and the second receiving groove 1041 are semi-circular grooves. When the first receiving groove 1031 and the second receiving groove 1041 are engaged, the resulting receiving space is a hollow cylindrical space that can be adapted to the rod-shaped adjusting part 102. By providing a limiting part on the circumferential surface of the adjusting part 102, and providing limiting mating parts on the groove walls of the first receiving groove 1031 and the second receiving groove 1041, in the locked state, the limiting mating parts engage with the limiting part, thereby fixing the adjusting part 102 within the receiving space formed by the first receiving groove 1031 and the second receiving groove 1041. This ensures that during the process of the cage car 300 being overturned by the cage loading and unloading equipment, the stop part 101 always abuts against the top of the cage car 300, preventing the cage car 300 from rushing out of the equipment.

[0050] In some embodiments, the limiting part is an external thread, and the limiting mating part is an internal thread that meshes with the external thread. Specifically, the circumferential surface of the adjusting part 102 is provided with an external thread, and the groove walls of the first receiving groove 1031 and the second receiving groove 1041 are both provided with half-turn internal threads. In the locked state, when the groove openings of the first receiving groove 1031 and the second receiving groove 1041 are aligned, the internal thread on the groove wall of the first receiving groove 1031 and the internal thread on the groove wall of the second receiving groove 1041 can be connected to form a complete internal thread. The internal thread meshes with the external thread to achieve the fixing effect of the adjusting part 102.

[0051] For example, to improve adjustment accuracy, the pitch of the external and internal threads can be designed to be smaller to achieve fine-tuning and precise positioning.

[0052] In some embodiments, the limiting portion includes a plurality of annular protrusions spaced apart along the length direction of the adjusting portion 102, and the limiting mating portion includes an annular groove that mates with the annular protrusions.

[0053] There are multiple annular grooves. In the locked state, when the openings of the first receiving groove 1031 and the second receiving groove 1041 are aligned, the annular protrusion is limited to the annular groove.

[0054] In other embodiments, the limiting portion may also include a plurality of annular grooves spaced apart along the length direction of the adjusting portion 102, and correspondingly, the limiting mating portion includes annular protrusions that mate with the annular grooves.

[0055] In one embodiment, the first locking part 103 is provided with a guide slope 1032. The vertical distance between the end of the guide slope 1032 away from the first receiving groove 1031 and the connecting part 105 is less than the vertical distance between the end of the guide slope 1032 near the first receiving groove 1031 and the connecting part 105. A limit hook 1033 is provided at the position of the guide slope 1032 near the opening of the first receiving groove 1031. The second locking part 104 is provided with a limit protrusion 1042. The limit protrusion 1042 can slide on the guide slope 1032 so that the first locking part 103 can rotate around the hinge axis between the first locking part 103 and the connecting part 105. In the unlocked state, the limit protrusion 1042 can abut against the limit hook 1033.

[0056] See Figure 2 As shown, the vertical distance d1 between the end of the guide slope 1032 away from the first receiving groove 1031 and the connecting part 105 is less than the distance d2 between the end of the guide slope 1032 near the first receiving groove 1031 and the connecting part 105. During the process of switching from the locked state to the unlocked state, the second locking part 104 rotates around the second hinge axis 107 in the direction of arrow A, the limiting protrusion 1042 slides on the guide slope 1032 and gives the guide slope 1032 a thrust, so that the first locking part 103 rotates around the first hinge axis 106 in the direction of arrow B. At this time, the first locking part 103 and the second locking part 104 gradually move away from the adjusting part 102 until the limiting protrusion 1042 abuts against the limiting hook 1033, and the first locking part 103 and the second locking part 104 stop relative movement. At this time, the locking mechanism is in the unlocked state, and the adjusting part 102 can move back and forth along its own axis to adjust the position of the stop part 101.

[0057] See Figure 4 As shown, to ensure that the second locking part 104 can rotate in the direction of arrow A, the second locking part 104 has an integrally formed extension 1043 near the first locking part 103. The extension 1043 is provided with a clearance space 1044 so that when the second locking part 104 can rotate in the direction of arrow A, it can avoid the adjustment part 102 and avoid interference with the adjustment part 102. A limiting protrusion 1042 is formed at the free end of the extension 1043.

[0058] In one embodiment, the locking device further includes an elastic reset member 108, one end of which is connected to the first locking part 103 and the other end of which is connected to the second locking part 104. The elastic reset member 108 is used to switch the locking mechanism from the unlocked state to the locked state.

[0059] For example, the resilient reset element 108 is a tension spring. See also Figure 1 As shown, when the locking mechanism is in the unlocked state, the tension spring is in the extended state. When the force applied to the second locking part 104 slowly disappears, the tension spring gradually returns to its original state. Under the elastic force of the tension spring, the first locking part 103 and the second locking part 104 are fastened together to fix the adjusting part 102.

[0060] In other embodiments, the locking device further includes a latching assembly that is detachably connected to the locking mechanism to engage or disengage the first locking portion 103 and the second locking portion 104.

[0061] For example, see Figure 7 and Figure 8 As shown, the snap-fit ​​assembly includes a connecting plate 110 and a latch 111. One end of the connecting plate 110 is hinged to the second locking part 104, and the other end of the connecting plate 110 is provided with a U-shaped groove 1101. A pin 112 is provided on the side of the U-shaped groove 1101 near the second locking part 104, and a locking element, such as a bolt 113, is provided on the side of the U-shaped groove 1101 away from the second locking part 104. For example, the bolt 113 is threaded to the connecting plate 110. Connect; one end of the latch 111 is provided with an elongated hole 1111, the length direction of the elongated hole 1111 is consistent with the length direction of the connecting plate 110, the pin 112 is limited in the elongated hole 1111, and the latch 111 can move relative to the pin 112. The other end of the latch 111 is provided with a groove 1112, and the bolt 113 can be limited in the groove 1112; the first locking part 103 is provided with a protrusion 114, and the protrusion 114 can be limited in the U-shaped groove.

[0062] See Figure 7As shown, in the locked state, the connecting plate 110 rotates around the hinge axis between itself and the second locking part 104 until the protrusion 114 is limited to the U-shaped groove. Then, the latch 111 rotates around the pin 112. Since the latch 111 can move relative to the pin 112 along the length direction of the elongated hole 1111, the latch 111 can be moved away from the bolt 113 first, so that the latch 111 can rotate to the position corresponding to the slot 1112 and the bolt 113. Then, the latch 111 is moved closer to the bolt 113 until the bolt 113 is limited to the slot 1112. The bolt 113 is tightened, so that the latch 111 is clamped and fixed between the head of the bolt 113 and the connecting plate 110, thereby fixing the first locking part 103 and the second locking part 104 together.

[0063] See Figure 8 As shown, in the unlocked state, loosen the bolt 113 and push the latch 111 away from the bolt 113, thereby separating the connecting plate 110 from the protrusion 114. At this time, the first locking part 103 and the second locking part 104 can be opened.

[0064] It should be noted that one end of the connecting plate can also be hinged to the first locking part 103, and the other end of the connecting plate 110 is provided with a U-shaped groove 1101. Correspondingly, the protrusion is provided on the second locking part 104.

[0065] In one embodiment, see Figure 1 and Figure 3 As shown, the locking mechanism also includes an operating lever 109, which is connected to the second locking part 104 to drive the second locking part 104 to rotate around the hinge axis between it and the connecting part 105.

[0066] For example, the operating lever 109 is fixedly connected to the second locking part 104. When an operator or automated equipment such as a robotic arm pulls the operating lever 109 in a set direction, it can drive the second locking part 104 to rotate around the second hinge axis 107 in the direction of arrow A. This, in turn, drives the first locking part 103 to rotate around the first hinge axis 106 in the direction of arrow B via the limiting protrusion 1042, until the limiting protrusion 1042 abuts against the limiting hook 1033. At this point, the first locking part 103 and the second locking part 104 stop moving relative to each other, and the locking mechanism is in the unlocked state. The set direction is not the same as the length direction of the operating lever 109, and it enables the second locking part 104 to rotate around the second hinge axis 107 in the direction of arrow A.

[0067] When pulling the operating lever 109, only the elastic force of the tension spring needs to be overcome. The lever arm of the operating lever 109 is long enough to be pulled easily, requiring very little effort. In the unlocked state, the adjusting part 102 can be moved to adjust the position of the stop part 101. This process can be done by one person, for example, by pulling the operating lever 109 with one hand and moving the adjusting part 102 with the other. When the stop part 101 abuts against the top of the cage 300, the operating lever 109 is slowly released. The first locking part 103 and the second locking part 104 engage together under the elastic force of the tension spring, and the locking mechanism is in the locked state. In the locked state, the openings of the first receiving groove 1031 and the second receiving groove 1041 are opposite each other. The internal thread on the groove wall of the first receiving groove 1031 and the internal thread on the groove wall of the second receiving groove 1041 mate to form a complete internal thread, which engages with the external thread on the adjusting part 102, achieving precise positioning and fixing of the adjusting part 102.

[0068] Of course, the operating lever can also be located on the first locking part 103 to drive the first locking part 103 to rotate about the hinge axis between it and the connecting part 105. For example, see Figure 8 As shown, when the operating lever is set in the first locking part 103, pulling the operating lever can drive the first locking part 103 to rotate around the first hinge axis 106. The second locking part 104 can rotate around the second hinge axis 107 under its own gravity until the limiting protrusion 1042 abuts against the limiting hook 1033. The first locking part 103 and the second locking part 104 stop moving relative to each other. At this time, the locking mechanism is in the unlocked state.

[0069] See Figures 9 to 12 As shown, this embodiment also provides a cage loading and unloading device, including a material box 201 and a locking device provided in this embodiment. The material box 201 is used to load the cage car 300. The top of the material box 201 is provided with an opening. The locking mechanism is installed on the side wall of the material box 201. The stop part 101 is provided near the top of the material box 201, and the adjusting part 102 can drive the stop part 101 to move along the height direction of the material box 201 so that the stop part 101 abuts against the top of the cage car 300.

[0070] In this embodiment, the cage loading and unloading device involves placing the cage trolley 300 inside the material box 201. With the device in the unlocked state, the adjusting part 102 slides relative to the locking mechanism, allowing for quick and easy adjustment of the stop part 101. This causes the stop part 101 to abut against the top of the cage trolley 300. The locking mechanism is then locked, and at this point, it is fixedly connected to the adjusting part 102, ensuring the stop part 101 remains in contact with the top of the cage trolley 300. The stop part 101 is not subjected to force, and the locking mechanism only bears the weight of the adjusting part 102 and the stop part 101. When the cage trolley 300 is rotated by a set angle (e.g., 150°) along with the loading and unloading device, the stop part 101 restricts the cage trolley 300 from moving diagonally downwards, preventing it from bursting out of the opening at the top of the material box 201. The unlocked state refers to the opening of the material box 201 facing upwards and perpendicular to the ground.

[0071] See Figure 12 As shown, after the cage car 300 is rotated to a set angle along with the cage loading and unloading equipment, the stop part 101 is subjected to pressure from the cage car 300. At the same time, the adjusting part 102 generates a pulling force on the first locking part 103 and the second locking part 104 in the axial direction of the adjusting part 102. This pulling force causes the first locking part 103 to tend to move around the first hinge axis 106 in the direction of arrow C, thereby further locking the first locking part 103 and the second locking part 104 to achieve a self-locking effect.

[0072] In one embodiment, see Figure 9 As shown, there are two adjusting parts 102 and two locking mechanisms. The two adjusting parts 102 are respectively connected to both ends of the stop part 101, and the two locking mechanisms are respectively disposed on two opposite side walls of the material box 201. By providing an adjusting part 102 at each end of the stop part 101, it is convenient to adjust the stop part 101, allowing it to rise or fall smoothly. This also ensures better contact between the stop part 101 and the top of the cage 300, enhancing the stopping effect. Since the two adjusting parts 102 are symmetrically arranged at both ends of the stop part 101, the adjusting parts 102 provide support and position adjustment for the stop part 101. The supporting force of the adjusting parts 102 on the stop part 101 comes from the locking mechanisms. The two locking mechanisms share the weight of the two adjusting parts 102 and the stop part 101, so the force on a single locking mechanism is smaller, making operation smoother and easier.

[0073] For example, the side wall of the material box 201 is provided with a crossbeam 2011, the locking mechanism is installed below the crossbeam 2011, and the crossbeam 2011 is provided with a through hole for the adjustment part 102 to pass through.

[0074] It should be noted that the material bin 201 and other structures of the cage loading and unloading equipment (such as the base 202, hydraulic cylinder 203, etc.) and their working principles are existing technologies and will not be described in detail here.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
