Description

Technical Field

[0001] The invention relates to the technical field of low-profile quay cranes, and in particular to an anchoring device for a translational beam and a quay crane. Background Art

[0002] With the development of multimodal transport by sea, land and air, many docks are built near airports, and dock loading and unloading equipment is subject to strict height restrictions. In this case, low-profile quay cranes with horizontal sliding beams have emerged. Unlike conventional quay crane beams that use pitching movements to achieve ship-passing conditions, this low-profile quay crane beam uses horizontal sliding movements to retract or extend to achieve ship-passing or ship loading and unloading operations, which effectively solves the problem of conventional quay cranes affecting aviation safety due to their super height.

[0003] The beam anchoring device of a conventional low-profile quay crane uses a square anchor plate inserted from top to bottom into a square anchor pit to fix the beam. In order to avoid the situation where the beam cannot be inserted due to positioning errors during operation, the anchor pit is often larger than the size of the anchor plate, that is, there is a certain gap between the anchor plate and the inner wall of the anchor pit. This causes the beam to micro-move or even impact due to the gap between the anchor plate and the anchor pit when the trolley is hoisted, affecting the operating accuracy and comfort of the driver in the quay crane cab. In addition, long-term micro-motion and impact will cause deformation of the anchor pit, affecting the service life and safety of the anchor device. Summary of the invention

[0004] In view of this, the present invention provides an anchoring device for a translational beam and a quay crane, which can automatically adjust the position, effectively eliminate the gap between the anchor plate and the anchor pit, extend the service life of the device, and improve the operating accuracy and comfort of the driver in the quay crane cab.

[0019] Furthermore, two arc-shaped guide rails are arranged on the fixing frame, a hole body for accommodating the fixing frame is arranged on the base, and a pad is arranged between the fixing frame and the inner side wall of the hole body, and the pad is used to adjust the position of the fixing frame.

[0020] Furthermore, a reinforcing rib is provided at the bottom of the fixing frame;

[0021] The bottom of the anchor plate is provided with an arc surface for abutting against the bottom surface of the anchor pit. When the rolling assembly is anchored in the anchor pit, the arc surface abuts against the bottom surface of the anchor pit.

[0022] A support plate for matching with the arc surface is also arranged on the bottom surface of the anchoring pit, and the support plate is located between the two arc guide rails.

[0023] Furthermore, the anchoring component also includes:

[0024] Two anchor pins, which are arranged on both sides of the upper end of the anchor plate. When the rolling assembly is anchored in the anchor pit, the two anchor pins are used to connect with the translational beam for locking;

[0037] The above technical solution of the present invention has at least one of the following beneficial effects:

[0038] The anchoring device of the translational beam according to the embodiment of the present invention is used for a quay crane and includes an anchoring seat and an anchoring assembly.

[0039] Specifically, the anchor seat is arranged at the anchor position of the translational beam, and an anchor pit is arranged on the anchor seat. The anchor assembly is arranged on the translational beam and located above the anchor seat, and the anchor assembly is used to cooperate with the anchor seat to lock the translational beam.

[0040] The anchor assembly may include an anchor plate and a driving member, the driving member is used to drive the anchor plate to move up and down, the lower end of the anchor plate is provided with a rolling assembly that can be opened or closed, the rolling assembly is used to be inserted into the corresponding anchor pit below it for anchoring, and the rolling assembly can abut the bottom surface of the anchor pit and open so that the rolling assembly fits the inner side surface of the anchor pit. As the rolling assembly moves upward and leaves the anchor pit, the rolling assembly can close.

[0041] When the translational beam needs to be anchored, the translational beam first translates to the anchoring position, the rolling assembly of the anchor assembly is located above the corresponding anchoring pit, and then the driving member drives the anchor plate to move downward. As the anchor plate is pressed down, the front end of the rolling assembly first abuts against the bottom surface of the anchoring pit, and begins to roll along the bottom surface of the anchoring pit and gradually opens until the rolling assembly abuts against the inner side surface of the anchoring pit. In addition, there may be certain positioning errors during the operation of the beam. When the rolling assembly abuts the bottom surface of the anchor pit, if the rolling assembly is biased to one side of the anchor pit (that is, it is not completely centered), then as the anchor plate continues to press down, one side of the rolling assembly will first abut against one side of the inner wall of the anchor pit. Since the anchor pit is fixed, as one side of the rolling assembly abuts against one side of the inner wall of the anchor pit and continues to open, the rolling assembly, the anchor plate and the translational beam move together, gradually guiding the center of the entire rolling assembly to move toward the center of the anchor pit, until the other side of the rolling assembly abuts against the other side of the inner wall of the anchor pit. At this time, the center of the rolling assembly coincides with the center of the anchor pit, realizing automatic position adjustment of the anchor assembly.

[0042] When the translation beam needs to be unanchored, the driver drives the anchor plate to move upward, driving the rolling assembly to gradually detach from the anchor pit. As the anchor plate is lifted, the rolling assembly rolls along the bottom of the anchor pit and gradually closes, eventually returning to its initial closed state, ready for the next anchoring operation.

[0043] Therefore, the anchoring device of the embodiment of the present invention can automatically adjust its position when the anchor plate is pressed down through a rolling component that can be opened or closed, thereby effectively eliminating the gap between the anchor plate and the anchor pit, extending the service life of the device, and improving the operating accuracy and comfort of the driver in the quay crane cab.

[0062] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not indicate quantity restrictions, but indicate the existence of at least one. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0064] Firstly, the anchoring device of the translational beam according to the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0065] like Figures 1 to 11 As shown, the anchoring device of the translational beam according to the first embodiment of the present invention is used for a quay crane (i.e., a shore container crane) and may include: an anchoring seat 100 and an anchoring assembly 200.

[0066] Specifically, the anchor seat 100 is arranged at the anchoring position of the translational beam, and an anchoring pit 121 is arranged on the anchor seat 100. The anchor assembly 200 is arranged on the translational beam and located above the anchor seat 100, and the anchor assembly 200 is used to cooperate with the anchor seat 100 to lock the translational beam.

[0067] The anchor assembly 200 may include an anchor plate 210 and a driving member 220, wherein the driving member 220 is used to drive the anchor plate 210 to move up and down, and a rolling assembly 230 that can be opened or closed is provided at the lower end of the anchor plate 210, and the rolling assembly 230 is used to be inserted into the corresponding anchor pit 121 below it for anchoring, and the rolling assembly 230 can abut against the bottom surface of the anchor pit 121 and open so that the rolling assembly 230 fits the inner side surface of the anchor pit 121. As the rolling assembly 230 moves upward and leaves the anchor pit 121, the rolling assembly 230 can close.

[0068] Combine the following Figures 1 to 11 , briefly describe the working process of the anchoring device of the embodiment of the present invention:

[0069] When the translational beam needs to be anchored, the translational beam is first translated to the anchoring position, the rolling assembly 230 of the anchor assembly 200 is located above the corresponding anchoring pit 121, and then the driving member 220 drives the anchor plate 210 to move downward. As the anchor plate 210 is pressed downward, the front end of the rolling assembly 230 first abuts against the bottom surface of the anchoring pit 121, and begins to roll along the bottom surface of the anchoring pit 121 and gradually opens until the rolling assembly 230 abuts against the inner side surface of the anchoring pit 121, completing the anchoring. In addition, there may be a certain positioning error during the operation of the translational beam. When the rolling component 230 abuts the bottom surface of the anchor pit 121, if the rolling component 230 is biased toward one side of the anchor pit 121 (that is, it is not completely centered), then as the anchor plate 210 continues to press down, one side of the rolling component 230 will first abut against the inner wall of one side of the anchor pit 121. Since the anchor pit 121 is fixed, as one side of the rolling component 230 abuts against the inner wall of one side of the anchor pit 121 and continues to open, the rolling component 230, the anchor plate 210 and the translational beam move together, gradually guiding the center of the entire rolling component 230 to move toward the center of the anchor pit 121 until the other side of the rolling component 230 abuts against the inner wall of the other side of the anchor pit 121. At this time, the center of the rolling component 230 coincides with the center of the anchor pit 121, thereby realizing automatic position adjustment of the anchor component 200.

[0070] When the translation beam needs to be unanchored, the driving member 220 drives the anchor plate 210 to move upward, driving the rolling assembly 230 to gradually detach from the anchor pit 121. As the anchor plate 210 is lifted, the rolling assembly 230 rolls along the bottom surface of the anchor pit 121 and gradually closes, and finally returns to the initial closed state, preparing for the next anchoring operation.

[0071] Therefore, the anchoring device of the embodiment of the present invention can automatically adjust its position when the anchor plate 210 is pressed down through the rolling component 230 that can be opened or closed, effectively eliminating the gap between the anchor plate 210 and the anchor pit 121, extending the service life of the device, and improving the operating accuracy and comfort of the driver in the quay crane cab.

[0072] In some embodiments of the present invention, Figures 7 to 9 As shown, the rolling assembly 230 may include: two wing plates 231 and two rolling elements 232. Specifically, the upper ends of the two wing plates 231 are hinged to the lower end of the anchor plate 210 through a pin shaft 233, and the two wing plates 231 are symmetrically arranged along the pin shaft 233. Each rolling element 232 is connected to the lower end of its corresponding wing plate 231, and the two wing plates 231 rotate around the pin shaft 233 to open or close the two rolling elements 232.

[0073] Therefore, when the anchor plate 210 is pressed down, the two wing plates 231 rotate outward around the pin shaft 233, driving the two rolling members 232 to open; when the anchor plate 210 is lifted, the two wing plates 231 can rotate inward around the pin shaft 233 by their own weight, driving the two rolling members 232 to close. The structure is simple, stable and reliable.

[0074] In some embodiments of the present invention, Figures 1 to 6 As shown, the anchoring seat 100 may include: a base 110 and two arc-shaped guide rails 120. The base 110 is arranged at the anchoring position of the translational beam. The two arc-shaped guide rails 120 are symmetrically arranged on the base 110, and an anchoring pit 121 is formed between the two arc-shaped guide rails 120, and the arc openings of the two arc-shaped guide rails 120 are both facing the anchoring pit 121.

[0075] The rolling element 232 may be a roller, and the inner diameter of the arc guide 120 matches the outer diameter of the rolling element 232. A first detection limit device 300 is correspondingly provided on each arc guide 120, and each first detection limit device 300 is used to detect the position of the corresponding rolling element 232 in the anchoring pit 121. That is to say, by designing the inner diameter of the arc guide 120 and the outer diameter of the rolling element 232 (roller) to match, it is ensured that there is no gap when the rolling element 232 abuts against the inner surface of the arc guide 120. When the rolling element 232 abuts against the arc guide 120 and fits with the inner surface of the arc guide 120, the first detection limit device 300 is activated and sends a signal to the control system of the translational beam, indicating that the anchor plate 210 has been inserted into place and the rolling assembly 230 has completed anchoring. The first detection limit device 300 may be, for example, a mechanical limit switch or a photoelectric switch, etc., which will not be described in detail in this application.

[0076] In some embodiments of the present invention, Figures 7 to 9 As shown, each wing plate 231 is also provided with a stopper 234, and when the rolling assembly 230 is closed, the two stoppers 234 abut against each other to support and limit the position. In some other embodiments, the stopper 234 is provided on only one wing plate 231, and the stopper 234 abuts against the inner side of the other wing plate 231 to achieve support and limit the position. Thus, the stopper 234 limits the minimum closing angle of the rolling assembly 230, effectively preventing the two wing plates 231 from being overly closed and unable to open, and also preventing the two wing plates 231 from swinging or colliding unnecessarily during the closing process.

[0077] In some embodiments of the present invention, Figures 1 to 6As shown, two arc-shaped guide rails 120 are arranged on the fixing frame 130, and a hole body (not shown) for accommodating the fixing frame 130 is arranged on the base 110, and a pad 140 is further arranged between the fixing frame 130 and the inner side wall of the hole body, and the pad 140 is used to adjust the position of the fixing frame 130. Therefore, by arranging the pad 140 between the fixing frame 130 and the inner side wall of the hole body, the pad 140 can be selected with different thicknesses or quantities as needed to fine-tune the position of the fixing frame 130, thereby eliminating the influence caused by installation errors or manufacturing errors, so that the rolling element 232 (roller) fits more closely with the arc-shaped guide rail 120 when the rolling assembly 230 is fully opened.

[0078] In some embodiments of the present invention, Figures 1 to 6 As shown, a reinforcing rib 131 is also provided at the bottom of the fixing frame 130. Fig. 9 As shown, the bottom of the anchor plate 210 is provided with an arc surface for abutting against the bottom surface of the anchor pit 121. When the rolling assembly 230 is anchored with the anchor pit 121, the arc surface abuts against the bottom surface of the anchor pit 121. A support plate 132 for matching with the arc surface is also provided on the bottom surface of the anchor pit 121, and the support plate 132 is located between the two arc guide rails 120.

[0079] That is to say, the anchoring device of the embodiment of the present invention, by providing the reinforcing ribs 131, enhances the overall rigidity and stability of the fixing frame 130, ensuring that it will not be deformed or damaged when subjected to a large load. The coordination of the arc surface and the support plate 132 increases the contact area between the anchor plate 210 and the anchoring pit 121, reduces the force on the rolling assembly 230, provides a more uniform supporting force, enhances the accuracy and stability of the anchoring, reduces impact and vibration, and prolongs the service life of the device.

[0080] In some embodiments of the present invention, Figures 1 to 4 As shown, the anchor assembly 200 may also include: two anchor pins 240, which are arranged on both sides of the upper end of the anchor plate 210. When the rolling assembly 230 is anchored with the anchoring pit 121, the two anchor pins 240 are used to connect with the translational beam for locking. The translational beam is provided with an ear plate 700 for correspondingly connecting with each anchor pin 240. Thus, the stability of the anchoring is further enhanced by the mechanical locking of the anchor pin 240 and the ear plate 700, and the coordinated locking of the rolling assembly 230 and the anchoring pit 121 ensures the stability of the translational beam when anchored, and prevents loosening or slipping due to external forces.

[0081] In some embodiments of the present invention, Figures 1 to 10As shown, the driving member 220 is a hydraulic push rod, which is controlled by a hydraulic system 500. The hydraulic push rod is arranged on the translational beam in the vertical direction, and the output end of the hydraulic push rod faces downward and is connected to the upper end of the anchor plate 210. The hydraulic system 500 may include an electromagnetic reversing valve 510, which is used to control the extension or retraction of the hydraulic push rod. The hydraulic system 500 may also include a balancing valve 520, which is used to balance the force of the hydraulic oil during the extension and retraction of the hydraulic push rod.

[0082] That is to say, in the anchoring device of the embodiment of the present invention, the hydraulic system 500 controls the hydraulic push rod to extend and retract through the electromagnetic reversing valve 510, so as to realize the lifting and landing of the anchor plate 210. At the same time, the hydraulic system 500 is provided with a balance valve 520 to keep the thrust of the hydraulic push rod stable, and to maintain a certain pressure after the anchor plate 210 is landed, so as to lock the anchor plate 210 and ensure safety. If the hydraulic system 500 fails, the movement of the anchor plate 210 can be realized by a manual pump, or an emergency action can be realized by connecting to an external open-loop emergency pump station through an interface. In addition, the hydraulic system 500 also includes mechanisms such as oil pumps, oil tanks, and other control valves, which can adopt corresponding mechanisms in the prior art, and this application will not elaborate on this.

[0083] In some embodiments of the present invention, Figures 1 to 4 As shown, the anchoring device may further include: a second detection and limiting device 400 and a sensing member 211. The second detection and limiting device 400 is arranged on the translational beam, and the sensing member 211 is arranged on the anchoring plate 210, and the sensing member 211 is used to cooperate with the second detection and limiting device 400 to limit the height of the upward movement of the anchoring plate 210.

[0084] Combine the following Figures 1 to 11 , further describing the working principle of the anchoring device of the embodiment of the present invention:

[0085] In the initial state, the anchor plate 210 is in the raised position, and the rolling assembly 230 is closed and away from the anchor pit 121. At this time, the hydraulic push rod is in the retracted state, and the anchor plate 210 is in a safe raised position. The second detection limit device 400 and the sensor 211 are in the untriggered state, ready to perform a downward pressing action.

[0086] The control system of the translational beam sends instructions to the electromagnetic reversing valve 510 of the hydraulic system 500 according to the working requirements, so that the hydraulic oil enters the rodless cavity of the hydraulic push rod, pushes the piston rod to move downward and extend, and drives the anchor plate 210 to be pressed down.

[0087] As the anchor plate 210 is pressed down, the rolling assembly 230 is gradually inserted into the anchor pit 121. When the two rolling members 232 of the rolling assembly 230 abut against the bottom surface of the anchor pit 121, as the anchor plate 210 continues to be pressed down, the two wing plates 231 rotate outward around the pin shaft 233, driving the two rolling members 232 to open.

[0088] The anchoring plate 210 continues to be pressed down until the rolling assembly 230 is completely embedded in the anchoring pit 121. At this time, the two wing plates 231 have been fully opened, and the two rolling members 232 are closely fitted with the inner surfaces of the two arc-shaped guide rails 120 to complete the anchoring.

[0089] After the anchor plate 210 is pressed down to complete the anchoring, the anchor pin 240 is automatically or manually inserted into the ear plate 700 on the translational beam to form a mechanical lock.

[0090] At the same time, when the first detection limit device 300 detects that the rolling assembly 230 has completely abutted the anchor pit 121, the control system starts the balance valve 520 to keep the pressure of the hydraulic push rod stable, ensuring that the anchor plate 210 is in a locked state to further prevent loosening or slipping.

[0091] When it is necessary to release the anchor, firstly, it is necessary to release the mechanical locking between the anchor pin 240 and the ear plate 700. The anchor pin 240 can be pulled out from the ear plate 700 manually or automatically to release the mechanical locking.

[0092] Afterwards, the control system of the translational beam sends a command to the electromagnetic reversing valve 510 of the hydraulic system 500, so that the hydraulic oil enters the rod chamber of the hydraulic push rod, pushing the piston rod to move upward and retract, driving the anchor plate 210 to lift.

[0093] As the anchor plate 210 is lifted, the two wing plates 231 of the rolling assembly 230 rotate inward around the pin shaft 233, driving the two rolling members 232 to roll along the bottom surface of the anchor pit 121 and gradually close until the two rolling members 232 return to the closed state and completely detach from the anchor pit 121.

[0094] As the anchor plate 210 moves upward, when the sensing element 211 on the anchor plate 210 triggers the second detection limit device 400, the control system will immediately stop the action of the hydraulic push rod to ensure that the anchor plate 210 stays in a safe lifting position.

[0095] Thus, through the cooperation of the electromagnetic reversing valve 510 and the balancing valve 520, the hydraulic system 500 can accurately control the extension and retraction of the hydraulic push rod, ensuring that the anchor plate 210 remains stable during the lifting and lowering process. The first detection limit device 300 and the second detection limit device 400 ensure that the anchor plate 210 will not be excessive during the lifting and lowering process, further enhancing the safety of anchoring.

[0096] In addition, through the design of the manual pump and the external emergency pump station, the present invention can still work normally in the event of a failure of the hydraulic system 500. This design ensures that the equipment will not lose function due to a failure of the hydraulic system 500 in an emergency, thereby improving the reliability and safety of the equipment.

[0097] In some embodiments of the present invention, Figures 7 to 9 As shown, the translational beam is provided with a guide mechanism 600 for cooperating with the up and down movement of the anchor plate 210. The guide mechanism 600 may include: a slider 610 and a slide rail (not shown). The slider 610 is provided on the anchor plate 210. The slide rail is provided on the translational beam in the vertical direction, and the slider 610 is slidably connected with the slide rail. Thus, the anchor plate 210 is ensured to move up and down smoothly, and the anchor plate 210 is effectively prevented from being laterally offset due to positioning errors or external forces when moving up and down, which affects the accuracy and stability of anchoring.

[0098] According to the second embodiment of the present invention, a quay crane (also known as a shore container crane) is Figures 1 to 11 As shown, it can include the anchoring device of any embodiment of the first aspect mentioned above.

[0099] According to the following Fig.11 , combined with Figures 7 to 9 , briefly introduce the working process of the quay crane's translational girder:

[0100] When the translational beam is in translation mode, the quay crane control system (such as PLC) determines whether the state of the spreader, the position of the spreader, the position of the trolley, the position of the anchor plate 210, the state of the trolley, etc. meet the requirements. If one item does not meet the requirements, the translational beam stops moving. When all the above conditions meet the requirements (for example, there is no load under the sling, the sling is above the corresponding crossbeam, the trolley is in the parking position, the anchor plate 210 is in a safe lifting position, and the trolley is in a stopped state), the driving device drives the translational beam to run to the specified position (i.e., the anchor position) at the rated speed, and the precise position of the translational beam is detected by the encoder of the driving device and the corresponding detection limit to ensure that the translational beam reaches the specified position. After the translational beam is in place, the indicator light is on, and by pressing the translational beam anchoring operation button, the hydraulic push rod pushes the anchor plate 210 downward (the rolling assembly 230 abuts against the bottom surface of the anchor pit 121 and opens), until the induction limit on both sides of the anchor pit 121 is activated, that is, the first detection limit device 300 detects that the rolling assembly 230 abuts against the inner wall of the anchor pit 121. At this time, the anchoring action is completed, the hydraulic push rod stops, and then the pressure of the hydraulic system 500 is automatically reduced to the set value of the balance valve 520 and maintained, ensuring the reliable anchoring of the translational beam.

[0101] Based on the above-mentioned embodiments of the present invention, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0102] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
