Description

An anti-roll support rod mechanism

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 15, 2023, with application number 202322194718.6 and invention name “A kind of anti-roll support rod mechanism”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of warehousing and logistics technology, and in particular to an anti-roll support rod mechanism. Background Art

[0003] AGV (Automated Guided Vehicle) and forklifts are commonly used handling equipment in the warehousing and logistics industry. Most of these handling equipment are equipped with multi-level gantries. When the inner-level gantry of the multi-level gantry is in a retracted state relative to the outermost gantry, the lifting height is low and the center of gravity of the vehicle is also low, the stability is good, and the multi-level gantry does not need a strut mechanism for support. However, when the inner-level gantry of the multi-level gantry is extended relative to the outer-level gantry, as the lifting height increases, the center of gravity of the vehicle increases synchronously with the extension of the inner gantry. At this time, the multi-level gantry is often not stable enough, and there is even a certain degree of shaking, resulting in greater risks in operations such as picking up and placing goods in this state. Therefore, a strut mechanism is needed to improve the stability of the inner-level gantry when it is extended.

[0004] Summary of the Invention

[0005] The present application aims to solve one of the technical problems in the related art to a certain extent. To this end, the present application provides an anti-roll strut mechanism that maintains stability when the inner level mast of a multi-level mast extends relative to the outer level mast.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides an anti-roll support rod mechanism, comprising a base frame, a limit frame, a sliding rod, a support rod, a connecting rod and a power member;

[0008] The support rod is rotatably connected to the base frame, the sliding rod is provided on the base frame, the sliding direction of the power member is constrained by the sliding rod, an elastic member is provided between the base frame and the power member, one end of the elastic member abuts against the base frame, and the other end abuts against the power member to push the power member, and the power member pushes the connecting rod to rotate, and the connecting rod rotates to drive the support rod to abut against the limit frame;

[0009] The anti-roll strut mechanism has a retracted state, in which the support rod abuts against the base frame.

[0010] In the technical solution provided by the present application, the power member moves in a direction away from the base frame under the push of the elastic member. At this time, the support rod generates a movement tendency in the same direction driven by the connecting rod. However, at this time, the end of the support rod is restricted by the base frame. Although it cannot move as a whole, it can rotate with the connection point between the support rod and the base frame as the center of the circle. Therefore, a series of movements are formed in which the elastic member pushes the power member, and the power member rotates the support rod through the connecting rod. When the support rod moves to abut the limit frame, the rotation of the support rod stops. At this time, the anti-roll support rod mechanism is fully opened. Under the joint action of the elastic member and the limit frame, the support rod provides stable support. Since the support rod is subjected to the thrust applied by the shelf to the elastic part and transmitted by the elastic part, and at the same time is subjected to the reverse thrust provided by the connecting rod, the thrust received by the connecting rod is provided by the contact between the power rod and the sliding rod, and the direction of the thrust is perpendicular to the sliding direction, forming a self-locking structure, so that the support rod remains stable at all times during the contact with the shelf, thereby keeping the multi-level door frame stable and avoiding shaking, thereby ensuring the safety of operations such as picking up and placing goods when the inner-level door frame is extended relative to the outer-level door frame.

[0011] In the technical solution provided by this application, although the power element is driven by an elastic element, the movement of the power element always remains on the same sliding path due to the constraints of the sliding rod, preventing the power element from collapsing and causing the entire anti-roll strut mechanism to fall apart. The sliding rod can be connected to the limit frame or not. When the sliding rod is not connected to the limit frame, the support height can be adjusted by simply adjusting the position of the limit frame. When the support rod abuts the base frame, the anti-roll strut mechanism enters a retracted state. At this time, the support rod does not provide any support, facilitating the retraction of the multi-stage gantry.

[0012] Optionally, the base frame includes a first base and a first rotating base connected to the first base, one end of the sliding rod is connected to the first base, and the supporting rod is rotatably connected to the first rotating base.

[0013] The base frame is divided into a base and a swivel. The base is used to mount the entire anti-roll support mechanism to the outside world and also provides a location for the slide bar. The swivel, on the other hand, provides the center of rotation for the support bar. If the position of the limit frame cannot be adjusted, the height of the support can be adjusted by adjusting the height of the swivel.

[0014] Optionally, a supporting roller is provided at the end of the support rod.

[0015] Optionally, the first base is provided with a receiving groove, the support rod enters the receiving groove, and the support roller abuts against the first base, so that the anti-roll support rod mechanism remains in a retracted state.

[0016] The supporting rollers can reduce friction with external shelves, etc. At the same time, the anti-roll support rod mechanism can be kept in a retracted state to avoid opening when not necessary.

[0017] Optionally, the other end of the sliding rod is connected to the limiting frame.

[0018] The other end of the slide bar is connected to the limit frame, so that the entire anti-roll support rod mechanism acts as a whole, which is convenient for storage and transportation after leaving the factory.

[0019] Optionally, the elastic member is sleeved on the sliding rod.

[0020] The elastic member is sleeved on the slide rod, which is the simplest and fastest assembly method, and also the most stable assembly method. The simple structure can not only ensure the function of the elastic member, but also prevent the elastic member from collapsing from the anti-roll support rod mechanism.

[0021] Optionally, the power member is provided with a first outer protrusion, and the first outer protrusion is used to push the power member to compress the elastic member.

[0022] The provision of the convex portion can not only enable the anti-roll strut mechanism to switch from the open state back to the retracted state through the support rod, but also enable the power part to move in the direction of the compressed elastic part by pushing the convex portion, and then further pull the support rod by pulling the connecting rod, so that the anti-roll strut mechanism can be switched from the open state back to the retracted state.

[0023] Optionally, the power member includes a power rod, and two of the power rod, the connecting rod and the sliding rod are respectively provided, which are symmetrically arranged with the support rod as the symmetry axis, and the rotation axes of the two connecting rods and the support rod are collinear.

[0024] Optionally, the base includes a second base and a second swivel connected to the second base, two sliding rods are respectively connected to the second base, two second swivels are provided, and the two second swivels are symmetrically arranged between the two sliding rods with the support rod as the symmetry axis. The two second swivels are respectively rotatably connected to the support rod, and the rotation axes of the two rotational connections are collinear.

[0025] Compared with only arranging the power rod, connecting rod, sliding rod and swivel seat on one side, arranging the above parts symmetrically with the support rod as the symmetry axis can make the entire anti-roll support rod mechanism more stable.

[0026] Optionally, the power member further includes a connecting member, and the two power rods are connected by the connecting member.

[0027] While a symmetrical setup can make the anti-roll strut mechanism more stable, the two power rods must remain synchronized when the struts are opened or retracted to avoid jamming. Therefore, a connector is used to connect the two power rods to maintain synchronization of movement on both sides of the symmetry axis.

[0028] Optionally, the power member is provided with a second outer protrusion, and the second outer protrusion is provided on the connecting member to push the power member to compress the elastic member.

[0029] The outer protrusion connected to the connecting piece pushes the two power rods simultaneously, further ensuring that the two power rods remain synchronized when the anti-roll strut mechanism switches from the open state to the retracted state, thereby enhancing the overall stability.

[0030] In a second aspect, an embodiment of the present application further provides a multi-stage gantry, wherein the multi-stage gantry is equipped with an anti-roll strut mechanism as described above, and the multi-stage gantry supports the shelf through the anti-roll strut mechanism.

[0031] Optionally, the multi-stage gantry further comprises: an inner gantry, an outer gantry and a lifting power assembly; the anti-roll strut mechanism is arranged on the outer gantry;

[0032] The inner mast is connected to the outer mast via a slide rail; the lifting power assembly is connected to the inner mast via a transmission mechanism, and the lifting power assembly and the transmission mechanism can drive the inner mast to extend or retract relative to the outer mast along the slide rail;

[0033] A protruding structure is provided on the inner mast. When the inner mast is extended relative to the outer mast, the protruding structure touches the first outer protrusion of the power member, and the first outer protrusion drives the power member to push the connecting rod to rotate, and the connecting rod rotates to drive the support rod to extend; when the inner mast is retracted relative to the outer mast, the protruding structure touches the first outer protrusion of the power member, and the first outer protrusion drives the power member to push the connecting rod to rotate, and the connecting rod rotates to drive the support rod to retract.

[0034] In a third aspect, an embodiment of the present application further provides an AGV transport vehicle, wherein the AGV transport vehicle is equipped with the aforementioned multi-stage gantry.

[0035] In a fourth aspect, an embodiment of the present application further provides a forklift equipped with the aforementioned multi-stage gantry.

[0036] The reasoning process of the beneficial effects of the multi-stage gantry, AGV transporter and forklift provided in this application is similar to the reasoning process of the beneficial effects of the aforementioned anti-roll strut mechanism, and will not be repeated here.

[0037] Of course, it is not necessary to achieve all the advantages described above at the same time when implementing any product or method of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of this application.

[0046] References in this specification to "one embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed herein. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0047] Example 1:

[0048] 1 to 4 , this embodiment provides an anti-roll strut mechanism for use on a multi-stage gantry of handling equipment such as AGVs and forklifts. The anti-roll strut mechanism includes a base frame, a limit frame 7, a slide bar 2, an elastic member 3, a support rod 4, a connecting rod 5, and a power member.

[0049] In this embodiment, the frame includes a first base 11 and a first swivel base 12. The first base 11 is used to secure the entire anti-roll strut mechanism to the outside world and can be mounted on the multi-stage gantry via the first base 11. Furthermore, the first base 11 also provides a mounting location for the slide bar 2. Two first swivel bases 12 are provided to support the rotation of the support rod 4. One end of the first swivel base 12 is mounted on the first base 11, and the other end is mounted with a support rod pivot. The support rod 4 is mounted on the pivot, allowing it to rotate about the pivot. The height of the first swivel base 12 is related to the support height, and the support height can be adjusted by adjusting the height of the first swivel base 12. The power element includes two power rods 61. Furthermore, two connecting rods 5 and two slide bars 2 are each provided. Therefore, the first swivel base 12, power rod 61, connecting rod 5, and slide bar 2 are symmetrically arranged on either side of the support rod 4, with the support rod 4 as the axis of symmetry.

[0050] The two first swivel seats 12 and the two slide bars 2 are fixedly connected to the first base 11 at the same time. The connection method can be welding, threaded connection, one-piece molding, etc., which are not limited here. The two first swivel seats 12 can be located between the two slide bars 2, so that the sliding force arm of the support bar 4 is on the outside of the rotating force arm to increase the stability of the movement of the support bar 4. The other ends of the two slide bars 2 are fixedly connected to the limit frame 7 at the same time, so that the entire anti-roll support rod mechanism as a whole can increase the strength of the anti-roll support rod mechanism and facilitate storage and transportation after leaving the factory. In other embodiments, the slide bar 2 may not be connected to the limit frame 7. When the slide bar 2 is not connected to the limit frame 7, it is only necessary to adjust the position of the limit frame 7 to achieve the purpose of adjusting the support height.

[0051] As shown in Figure 4, the elastic member 3 is positioned between the first base 11 of the base frame and the power rod 61 of the power member. One end of the elastic member 3 pushes against the first base 11 of the base frame, and the other end pushes against the power rod 61 of the power member. In this embodiment, the elastic member 3 can be a compression spring. In other embodiments, a torsion spring or the like can also be used, which is not limited here. When a compression spring is used, the elastic member 3 can be mounted on the slide rod 2. This method is simple, quick, and relatively stable, ensuring the compression spring's effectiveness while preventing it from collapsing from the anti-roll strut mechanism.

[0052] On one side of the axis of symmetry, the power member is pivotally connected to one end of the connecting rod 5, and the other end of the connecting rod 5 is pivotally connected to the support rod 4. The support rod 4 is pivotally connected to the first rotating seat 12 of the base frame. When the elastic member 3 is compressed, it generates an elastic force that pushes the power member. The power member is used to drive the support rod 4 to abut the limit frame through the connecting rod 5. The power rod 61 of the power member is constrained in its sliding direction by the sliding rod 2. Under the constraint of the sliding rod 2, the movement of the power member always remains on the same sliding path, preventing the power member from breaking apart and causing the entire anti-roll strut mechanism to fall apart. Under the push of the elastic member 3, the power member moves away from the first base 11. At this time, driven by the connecting rod 5, the support rod 4 tends to move in the same direction. As the support rod 4 moves, the end of the support rod 4 contacts the first rotating seat 12. Although it cannot move as a whole due to the constraint of the first rotating seat 12, it can rotate around the connection point between the support rod 4 and the first rotating seat 12. Thus, a series of movements is formed in which the elastic member 3 pushes the power member, which in turn rotates the support rod 4 via the connecting rod 5. When the support rod 4 abuts the stop bracket, rotation of the support rod 4 ceases, and the power rod 61, supported by the compression spring, causes the support rod 4 to reach the limit position of the stop bracket 7. In this embodiment, the support rod 4 is perpendicular to the axis of the compression spring at a 90° angle. In other embodiments, the angle between the support rod 4 and the axis of the compression spring can be adjusted by the position of the stop bracket 7. At this point, the anti-roll strut mechanism is fully open, and the end of the support rod 4 is provided with a support roller 8, which reduces friction with external racks 9 and the like.

[0053] As shown in Figure 3, the support force provided by the anti-roll strut mechanism to the multi-stage gantry comes from the contact between the support rollers 8 and the shelves 9. The multi-stage gantry is supported by the support rods 4, support rollers 8, connecting rods 5, etc. The design length of the support rods 4 is approximately equal to the distance between the outer contour of the multi-stage gantry and the shelves 9. When the inner-level gantry is extended, the AGV or forklift performs high-level operations. Since the anti-roll strut mechanism at the top of the outer-level gantry will contact the edge of the shelves 9, the shelves 9 can provide a certain amount of support for the anti-roll strut mechanism, thereby reducing the overall swing angle of the multi-stage gantry, thereby preventing the multi-stage gantry of the AGV or forklift from tipping over.

[0054] At the initial moment when the anti-roll strut mechanism contacts the shelf 9, there will be a vertical displacement as shown in Figure 3. The support roller 8 installed on the support rod 4 can provide rotational freedom around the support roller 8's own rotation axis, so that the anti-roll strut mechanism still has vertical freedom after contacting the shelf 9, thereby preventing the anti-roll strut mechanism from being affected by the vertical displacement and getting stuck. The direction of the support force provided by the shelf 9 to the anti-roll strut mechanism is the same as the length direction of the support rod 4. Since the length direction of the support rod 4 is 90° perpendicular to the freedom direction of the power rod 61, the direction of the support force provided by the shelf 9 to the anti-roll strut mechanism is perpendicular to the freedom direction of the power rod 61, thereby forming a self-locking structure. Under the joint action of the elastic member 3 and the limit frame 7, the support rod 4 provides stable support. Since the support rod 4 is subjected to the thrust transmitted by the elastic member 3 and the reverse thrust provided by the connecting rod 5, the thrust received by the connecting rod 5 is provided by the contact between the power rod 61 and the slide rod 2. The direction of the thrust is perpendicular to the sliding direction, which constitutes a self-locking structure, so that the support rod 4 remains stable at all times during the contact with the shelf 9, thereby keeping the multi-stage gantry stable and avoiding shaking. There are no common problems of electronic control solutions such as poor control coordination. The self-locking function is achieved without adding additional power, with a simple structure and low cost, ensuring the safety of operations such as picking up and placing goods when the inner-level gantry is extended relative to the outer-level gantry, and can effectively reduce the amount of shaking when the multi-stage gantry AGV or forklift is operating at a high position.

[0055] Because the anti-roll strut mechanism provided in this embodiment is symmetrically arranged with the support rod 4 as the axis of symmetry, the rotation axes of the two connecting rods 5 and the support rod 4 are collinear, and the rotation axes of the two first swivel seats, which are respectively connected to the two points of the support rod 4 at rotation, should also be collinear. This embodiment is described using one side of the axis of symmetry as an example. Those skilled in the art will appreciate that with an axisymmetric arrangement, the positional relationship, connection relationship, and transmission relationship of the parts on both sides can be adaptively adjusted. Using a symmetrical arrangement with the support rod 4 as the axis of symmetry can make the entire anti-roll strut mechanism more stable.

[0056] Since the power member includes two power rods 61, the power member also includes a connecting member 62, and the two power rods 61 are connected by the connecting member 62. This allows the power rods 61 on both sides to maintain necessary synchronization when the support rod 4 is opened or retracted, maintaining the synchronization of movement on both sides of the symmetry axis to avoid jamming.

[0057] As shown in Figure 4, the anti-roll strut mechanism provided in this embodiment has a retracted state. The power member is provided with a first protrusion 63, which is arranged on the connecting member 62 and is used to push the power member to compress the elastic member 3. The provision of the first protrusion 63 not only allows the anti-roll strut mechanism to switch from the retracted state to the open state, but also allows the power member to move in the direction of compressing the elastic member 3 by pushing the first protrusion 63, thereby further pulling the supporting rod 4 by pulling the connecting rod 5, switching the anti-roll strut mechanism from the open state back to the retracted state. This does not reduce the impact on the overall vehicle dimensions and is suitable for conventional high-bay rack 9 storage environments.

[0058] The first base 11 is provided with a receiving slot 111. Since the anti-roll strut mechanism in this embodiment is symmetrically arranged about the support rod 4, the receiving slot 111 and the first base 11 are necessarily located between the two first rotating seats 12. The first protrusion 63 is pushed toward the compression elastic member 3, causing the power member to move as a whole. This movement causes the power rod 61 to pull the connecting rod 5, which in turn pulls the support rod 4 into the receiving slot 111. At this point, the support rod 4 abuts the first base 11 of the frame, and the anti-roll strut mechanism enters a retracted state. The support rod 4 no longer provides any support, facilitating the retraction of the multi-stage gantry. Simultaneously, the support roller 8 abuts the first base 11, maintaining the anti-roll strut mechanism in the retracted state and preventing it from being opened unnecessarily. The first protrusion 63 on the connecting member 62 simultaneously pushes the two power rods 61, further ensuring synchronization when the anti-roll strut mechanism switches from the open state to the retracted state, enhancing overall stability.

[0059] Example 2:

[0060] This embodiment differs from the first embodiment in that, in this embodiment, there is only one slide bar 2 and one swivel seat, and correspondingly, there is only one elastic member 3, connecting rod 5, and power rod 61. In this case, the power rod 61 is the power member. On the same side of the support rod 4, the elastic member 3 is sleeved on the slide bar 2, with one end pushing against the base and the other end pushing against the power rod 61. The movement of the power rod 61 is constrained by the slide bar 2. The power rod 61 is rotationally connected to one end of the connecting rod 5, the other end of the connecting rod 5 is rotationally connected to the support rod 4, and the support rod 4 is rotationally connected to the swivel seat. Since there is only one power rod 61, the connecting member is no longer necessary in this embodiment, and the outer protrusion that pushes the power rod 61 to move in the direction in which the compression elasticity is compressed can be directly provided on the power rod 61.

[0061] At the same time, this specification also provides a multi-stage gantry I. As shown in Figure 5, the multi-stage gantry I provided in this specification is installed with the anti-roll strut mechanism II described in Example 1 or Example 2. The anti-roll strut mechanism II is installed on the side of the multi-stage gantry I close to the shelf. The multi-stage gantry I is supported on the shelf by the anti-roll strut mechanism II described in Example 1 or Example 2.

[0062] In one possible embodiment, a multi-stage mast I includes an inner mast, an outer mast, and a lifting power assembly. The inner and outer masts may be connected by slide rails, which may include components such as rollers and slots, enabling the inner mast to slide relative to the outer mast via the slide rails. Specifically, the inner mast may slide relative to the outer mast along the length of the outer mast, allowing the inner mast to extend or retract along the length of the outer mast.

[0063] The lifting power assembly can be installed on either the inner or outer mast. In one example, to reduce the weight of the inner mast and facilitate its extension or retraction, the lifting power assembly can be installed on the outer mast. The lifting power assembly is connected to the inner mast via a transmission mechanism, which can be a chain, belt, gear, or a combination of these. The lifting power assembly and transmission mechanism can drive the inner mast to slide, allowing the inner mast to extend or retract relative to the outer mast along the slide rails.

[0064] The anti-roll strut mechanism II is provided on the outer mast. Specifically, the anti-roll strut mechanism II can be fixedly connected to the outer mast by screws or welding. A protrusion structure is provided on the inner mast. When the inner mast is extended, the protrusion structure can drive the support rod 4 of the anti-roll strut mechanism II to extend. When the inner mast is retracted, the protrusion structure can drive the support rod 4 of the anti-roll strut mechanism II to retract. Specifically, when the inner mast is extended relative to the outer mast, the protrusion structure touches the first outer protrusion 63 of the power member, and the first outer protrusion 63 drives the power member to push the connecting rod 5 to rotate, and the connecting rod 5 rotates to drive the support rod 4 to extend. When the inner mast is retracted relative to the outer mast, the protrusion structure touches the first outer protrusion 63 of the power member, and the first outer protrusion 63 drives the power member to push the connecting rod 5 to rotate, and the connecting rod 5 rotates to drive the support rod 4 to retract.

[0065] In a possible embodiment, an actuator may be installed on the inner mast. The actuator may be a structure such as a robotic arm, roller or track, etc., for taking and placing goods, and the actuator may be extended or retracted along the length direction of the inner mast.

[0066] Furthermore, this specification also provides an AGV transporter equipped with the aforementioned multi-stage gantry I.

[0067] The Multi-Level Mast I can be mounted vertically on the chassis of an AGV. It consists of an inner and outer gantry. The inner gantry houses an actuator, which controls the loading and unloading of goods. The actuator can be extended or retracted along the length of the inner gantry, allowing it to be raised or lowered along the height of the AGV to facilitate loading and unloading at various heights. The inner gantry can be extended or retracted relative to the outer gantry. When the inner gantry is extended, the support rods 4 of the anti-roll brace mechanism II extend to support the surrounding shelves, maintaining the stability of the entire system.

[0068] And, a forklift equipped with the aforementioned multi-stage mast.

[0069] The Multi-Level Mast I can be mounted vertically on the forklift chassis. It consists of an inner and outer mast. The inner mast is equipped with an actuator, which controls the loading and unloading of goods. The actuator can be extended or retracted along the length of the inner mast, allowing it to be raised or lowered along the height of the forklift to facilitate loading and unloading at various heights. The inner mast can be extended or retracted relative to the outer mast. When the inner mast is extended, the support rods 4 of the anti-roll brace mechanism II extend to support the surrounding racks, maintaining the stability of the entire system.
