Description

Technical Field

[0001] This utility model relates to the field of hoisting devices, and in particular to a cross-bay hoisting device with a bridge crane. Background Technology

[0002] Currently, container handling at port terminals is mainly done by forklifts. Forklifts have short lifespans and low efficiency, often requiring multiple trucks to wait for them to operate. Each forklift requires multiple workers working in three shifts, and manual operation on-site is unsafe. Therefore, there is an urgent need for a new type of container handling equipment for port terminals, such as using bridge cranes. Bridge cranes are easy to maintain and have low costs. However, because bridge cranes are rail-mounted cranes, they can only operate within a certain length of the track in the yard, meaning their work area is relatively fixed and they cannot be moved to other tracks. Since bridge cranes cannot operate across rails within the yard, each set of tracks in the yard needs to be equipped with a bridge crane, resulting in a large number of bridge cranes required, high investment, low utilization rate, and high operating costs, leading to excessively high operating costs. Utility Model Content

[0003] The purpose of this utility model is to propose a cross-bay hoisting device with a bridge crane. The bridge crane moves in the loading and unloading area and is transferred to the cross-bay flatcar at the end of the loading and unloading area.

[0008] Optimally, the transshipment flatcar includes: side frames, connecting beams, moving components, and flatcar track beams; The side frame is connected to the flatcar track beam at its lower end, one end of the connecting beam is connected to the top of one side of the side frame, and the other end of the connecting beam is connected to the top of the other side of the side frame; the connecting beam, the flatcar track beam, and the side frames on both sides form a hollow area around each other; The side frame or connecting beam is connected to the moving component, which is used to drive the transverse flatcar to move laterally; the flatcar track beam is provided with a longitudinally extending flatcar receiving track.

[0019] like Figure 1-10 A cross-bay lifting device with a bridge crane includes: a crane running track 1, a cross-bay running track 2, a bridge crane 3, and a cross-bay flatcar 4. A plurality of crane running tracks 1 are arranged longitudinally, with adjacent crane running tracks 1 spaced apart to form loading and unloading areas 101; the cross-shell running track 2 passes laterally through the plurality of loading and unloading areas 101; The bridge crane 3 moves longitudinally along the crane running track 1 on both sides of the loading and unloading area 101; the cross-bay flatcar 4 is provided with a longitudinal flatcar track beam 40, and the cross-bay flatcar 4 moves laterally along the cross-bay running track 2, so that the cross-bay flatcar 4 passes laterally through multiple loading and unloading areas 101; when the flatcar track beam 40 moves to be longitudinally aligned with the crane running track 1, the bridge crane 3 moves between the crane running track 1 and the flatcar track beam 40, so that the bridge crane 3 leaves or enters the loading and unloading area 101; after the bridge crane 3 enters the cross-bay flatcar 4, the cross-bay flatcar 4 drives the bridge crane 3 to move laterally, so that the bridge crane 3 moves to be longitudinally aligned with any one of the loading and unloading areas 101.

[0020] This solution provides a cross-bay lifting device with a bridge crane. The bridge crane 3 moves in the loading and unloading area 101 and is transferred to the cross-bay flatcar 4 at the end of the loading and unloading area 101. The cross-bay flatcar 4 drives the bridge crane 3 to move in any loading and unloading area 101, realizing cross-bay operation of a single bridge crane 3 and solving the problem of increased costs caused by the need to configure multiple bridge cranes 3 in the existing terminal yard.

[0021] Specifically, the basic framework of the transshipment hoisting device is mainly a Bailey bridge. For example, the rails and other structures in the framework are supported by the Bailey bridge. For example, the structures in the air, such as the crane running rail 1 and the transshipment running rail 2, are supported by the Bailey bridge. Transshipment refers to the transfer between loading and unloading areas 101. The crane running rail 1 extends longitudinally, and there are multiple crane running rails 1. The loading and unloading areas 101 are formed between two adjacent crane running rails 1. That is, there are multiple loading and unloading areas 101, which are arranged laterally. The bridge crane 3 is movably installed on the crane running rail 1 and can be moved to a certain longitudinal position of the crane running rail 1 as needed. The bridge crane 3 can lift or lower the containers below it, and after lifting or lowering, until the loading and unloading area 101 has completed the stacking or retrieval of containers. The cross-bay running track 2 is located at the end of the loading and unloading area 101, and it passes laterally through several loading and unloading areas 101. The cross-bay flatcar 4 is movably installed on the cross-bay running track 2, and it can move to be longitudinally aligned with any one of the loading and unloading areas 101. The cross-bay flatcar 4 is equipped with a flatcar track beam 40. When the cross-bay flatcar 4 is longitudinally aligned with the loading and unloading area 101, the flatcar track beam 40 is longitudinally aligned with the crane running track 1, and the flatcar track beam 40 and the crane running track 1 are located on the same axis. At this time, the bridge crane 3 can move from the loading and unloading area 101 along the crane running track 1 to detach from the loading and unloading area 1. 01, and seamlessly transfer to the flatcar track beam 40 of the cross-bay flatcar 4; since the bridge crane 3 has completely detached from its loading and unloading area 101, the cross-bay flatcar 4 can be started, and the cross-bay flatcar 4 drives its bridge crane 3 to move on the cross-bay running track 2, so that the bridge crane 3 moves laterally to align with the target loading and unloading area 101; the bridge crane 3 then moves from the flatcar track beam 40 to the crane running track 1 of the target loading and unloading area 101, so that the bridge crane 3 can be transferred from the cross-bay running track 2 to the new loading and unloading area 101, and then perform the stacking or picking of containers by the bridge crane 3. Thus, the cross-bay flatcar 4 of this solution can drive the bridge crane 3 to move to any loading and unloading area 101, realizing the cross-bay operation of a single bridge crane 3, and solving the problem of increased costs caused by the need to configure multiple bridge cranes 3 in the existing terminal yard.

[0022] Optimally, it also includes: anchoring device 5; The anchoring device 5 includes: an anchoring rod 51, an anchor seat 52, and an anchoring push rod driver 53; The output end of the anchoring push rod driver 53 is connected to the anchoring rod 51 and is used to drive the anchoring rod 51 to move to be limited to or disengaged from the anchor seat 52; One of the anchor rod 51 and the anchor seat 52 is disposed on the bridge crane 3, and the other is disposed on the cross-shell flatcar 4. When the anchor rod 51 moves to its limit position at the anchor seat 52, the bridge crane 3 is limited to the cross-shell flatcar 4; and / or one of the anchor rod 51 and the anchor seat 52 is disposed on the cross-shell flatcar 4, and the other is disposed on the cross-shell running track 2. When the anchor rod 51 moves to its limit position at the anchor seat 52, the cross-shell flatcar 4 is limited to the cross-shell running track 2.

[0023] An anchoring device 5 can be installed between the bridge crane 3 and the cross-bay flatcar 4, and also between the cross-bay running track 2 and the cross-bay flatcar 4. The anchoring device 5 is used to anchor the bridge crane 3 or the cross-bay flatcar 4, thereby preventing the bridge crane 3 or the cross-bay flatcar 4 from shifting during the cross-bay process and improving the movement stability of the bridge crane 3 and / or the cross-bay flatcar 4. Specifically, the output end of the anchoring push rod driver 53 is connected to the anchoring rod 51. When it is necessary to anchor the bridge crane 3 or the cross-bay flatcar 4, the anchoring push rod driver 53 can be activated. The anchoring push rod driver 53 drives the anchoring rod 51 to move to the anchor seat 52. Since the anchoring rod 51 is limited to the anchor seat 52, the bridge crane 3 and the cross-bay flatcar 4 are mutually anchored, and / or the cross-bay flatcar 4 and the cross-bay running track 2 are mutually anchored, thereby preventing the anchored two from undergoing unexpected relative displacement under extreme weather conditions such as storms and improving the stability when stationary.

[0024] The anchoring push rod actuator 53 can be replaced by a known mechanism with a driving function, which can drive rotation or movement, such as a cylinder, hydraulic cylinder, a combination of a motor and a lead screw, a combination of a motor and a reducer, a combination of gears and racks, etc., as long as it can drive the anchoring rod 51 to move. For example, in the figure, the anchoring push rod actuator 53 is a cylinder, which drives the anchoring rod 51 to move linearly to the anchor seat 52.

[0025] Optimally, it also includes: windproof component 6; The windproof component 6 includes: a windproof actuator 61 and a windproof iron wedge 62; The output end of the windproof drive 61 is connected to the windproof wedge 62 and is used to drive the windproof wedge 62 to move closer to or further away from the flatcar track beam 40. When the windproof wedge 62 is close to the flatcar track beam 40, the bridge crane 3 moves to abut against the windproof wedge 62, and the windproof wedge 62 restricts the bridge crane 3 from moving on the flatcar track beam 40.

[0026] This design also includes a windproof component 6 installed at the flatcar track beam 40. Its windproof actuator 61 drives the windproof wedge 62 to move closer to or further away from the flatcar track beam 40. When the windproof wedge 62 moves closer to the flatcar track beam 40, it is within the movement range of the bridge crane 3. The bridge crane 3 will abut against the windproof wedge 62, which uses friction or blocking force to fix the bridge crane 3, thereby limiting the bridge crane 3 to the flatcar track beam 40 and preventing it from being blown away by the wind. At the same time, combined with the anchoring device 5 between the bridge crane 3 and the cross-shaped flatcar 4, the anchoring device 5 and the windproof component 6 together limit the bridge crane 3, forming a double locking effect on the bridge crane 3 on the cross-shaped flatcar 4.

[0027] The windproof actuator 61 can be replaced by a known mechanism with a driving function. It can drive rotation or drive movement, such as a cylinder, hydraulic cylinder, a combination of a motor and a lead screw, a combination of a motor and a reducer, a combination of gears and racks, etc., as long as the windproof actuator 61 can move. For example, in the figure, the windproof actuator 61 is a motor, which drives the windproof wedge 62 to rotate until it abuts against the flatcar track beam 40, so as to restrict the movement of the bridge crane 3 at the end of its movement.

[0028] Optimally, it also includes: a track locking device 7; The track locking device 7 includes: a track locking rod 71, a locking seat 72, and a track locking push rod driver 73; One of the track locking rod 71 and the locking seat 72 is disposed on the crane running track 1, and the other is disposed on the flatcar track beam 40; the output end of the track locking push rod driver 73 is connected to the track locking rod 71, and is used to drive the track locking rod 71 to move to the limit of being located or disengaged from the locking seat 72; before the bridge crane 3 enters or disengages from the crane running track 1, the track locking rod 71 moves to the limit of being located at the locking seat 72, so that the crane running track 1 and the flatcar track beam 40 are fixed.

[0029] A track locking device 7 can be installed between the crane running track 1 and the flatcar track beam 40. The track locking device 7 is used to lock the crane running track 1 and the flatcar track beam 40, improving the movement stability of the crane when entering and exiting the cross-shaped flatcar 4. Specifically, the output end of the track locking push rod driver 73 is connected to the track locking rod 71. When the bridge crane 3 is about to enter the cross-shaped flatcar 4, or when the bridge crane 3 is about to disengage from the cross-shaped flatcar 4, the track locking push rod driver 73 can be activated. The track locking push rod driver 73 drives the track locking rod 71 to move to the locking seat 72. Since the track locking rod 71 is limited to the locking seat 72, the crane running track 1 and the flatcar track beam 40 are fixed to each other, thereby preventing the crane running track 1 or the flatcar track beam 40 from undergoing unexpected displacement when the bridge crane 3 enters and exits the cross-shaped flatcar 4, and improving the stability of the bridge crane 3 entering the cross-shaped flatcar 4.

[0030] The track locking push rod actuator 73 can be replaced by a known mechanism with a driving function. It can drive rotation or drive movement, such as a cylinder, hydraulic cylinder, a combination of a motor and a lead screw, a combination of a motor and a reducer, a combination of gears and racks, etc., as long as it can drive the track locking rod 71 to move. For example, in the figure, the track locking push rod actuator 73 is a cylinder, which drives the track locking rod 71 to move linearly to the limit position of the locking seat 72.

[0031] Optimally, the transshipment flatcar 4 includes: a side frame 41, a connecting beam 42, a moving assembly 43, and a flatcar track beam 40; The side frame 41 is connected to the flatcar track beam 40 at its lower end. One end of the connecting beam 42 is connected to the top of one side of the side frame 41, and the other end of the connecting beam 42 is connected to the top of the other side of the side frame 41. The connecting beam 42, the flatcar track beam 40, and the side frames 41 on both sides form a hollow area 401. The side frame 41 or connecting beam 42 is connected to the moving component 43, which is used to drive the transverse flatcar 4 to move laterally; the flatcar track beam 40 is provided with a longitudinally extending flatcar receiving track 402.

[0032] The flatbed trolley 4 of this design uses connecting beams 42 to connect the upper parts of the side frames 41 on both sides, and the lower part of the side frames 41 is connected to the flatbed track beam 40. The three of them surround each other to form a hollow area 401 with a certain height, which can maximize the space in the middle of the flatbed trolley 4, thereby avoiding interference from other structures in the middle of the flatbed trolley 4. The flatbed track beam 40 can receive cranes with objects underneath, solving the problem that it is inconvenient to transfer objects under existing cranes across the trolley.

[0033] Specifically, the side frame 41 is connected to the flatcar track beam 40 below, and a connecting beam 42 is connected to the top of the side frame 41. The connecting beam 42 connects the left and right side frames 41 into one unit, forming a hollow area 401 with a certain height between the three. The hollow area 401 is located in the middle of the cross-shaped flatcar 4, which can maximize the space in the middle of the cross-shaped flatcar 4. At the same time, since the side frame 41 or the connecting beam 42 is connected to the moving component 43, and the connecting beam 42 extends laterally, the moving component 43 serves as the drive source for the cross-shaped flatcar 4, which can drive the entire cross-shaped flatcar 4. The body moves laterally, allowing the cross-bay flatcar 4 to operate laterally across the cross-bay, transferring materials laterally from one loading / unloading area 101 to another. Simultaneously, the moving component 43 is installed on the cross-bay running track 2, effectively suspending the cross-bay flatcar 4 above it. The open area 401 is essentially suspended in mid-air. Below the open area 401, the flatcar receiving track 402 receives the crane. The crane moves longitudinally, docking with the flatcar receiving track 402 and being guided into the open area 401. Because the flatcar track beam 40 is located below the open area 401, the height difference between the flatcar track beam 40 and the connecting beam 42 provides sufficient space for the crane, accommodating cranes of different heights. Furthermore, since the flatcar track beam 40 is located below the open area 401, when the crane enters the flatcar receiving track 402, the cross-bay flatcar 4 does not create any obstruction below the crane, allowing objects to protrude below it. Therefore, there are no restrictions on installing or carrying any objects below the crane. Therefore, this solution can maximize the space in the middle of the cross-bay flatcar 4, thereby avoiding interference from other structures in the middle of the cross-bay flatcar 4. The flatcar track beam 40 can receive a crane with objects underneath, solving the problem that it is inconvenient to transfer objects under existing cranes.

[0034] The moving component 43 can be implemented by a known mechanism with a driving movement function, as long as it can drive the transverse flatcar 4 to move.

[0035] Optimally, it also includes: bottom beam 44; The bottom beam 44 is connected to the flatcar track beams 40 on both sides, with the connection position close to one end of the flatcar track beam 40.

[0036] This design connects the two flatcar track beams 40 on both sides to the bottom beam 44, and the flatcar track beam 40 is equipped with a flatcar receiving track 402. This means that the flatcar receiving track 402 is connected to the crane through the bottom beam 44, which can improve the rigidity of the whole machine structure and make the cross-crane operation more stable and reliable. At the same time, the connection point of the bottom beam 44 is close to the end of the flatcar track beam 40, so the bottom beam 44 will not interfere with the crane in the hollow area 401. This can both improve the rigidity of the whole machine structure and maximize the space of the hollow area 401.

[0037] The flatcar track beams 40 on both sides are connected to the bottom beam 44 at one end, and the flatcar track beams 40 on both sides are hollowed out to form a hollow opening 403 between the other ends; the flatcar receiving track 402 extends longitudinally from the hollow opening 403 toward the bottom beam 44.

[0038] One end of the two flatcar track beams 40 is connected to the bottom beam 44; the other end of the two flatcar track beams 40 is hollow (without other structural connection) to form a hollow opening 403. The crane can enter the hollow area 401 through the hollow opening 403. One end of the flatcar receiving track 402 is close to the hollow opening 403, which facilitates docking with the crane near the hollow opening 403 and improves the smoothness and stability of the crane entering the hollow area 401.

[0039] Optimally, it also includes: crane stop 45; The crane stop 45 is fixed to the flatcar track beam 40 and is located at the end of the flatcar receiving track 402 away from the cutout 403.

[0040] This design provides a crane stop 45 at one end of the flatcar track beam 40, which is away from the cutout 403. When the flatcar receiving track 402 is connected to the crane's moving wheel, the crane moves along the flatcar receiving track 402. The moving wheel will abut against the crane stop 45 at the end of the movement, thereby restricting the moving wheel from continuing to move and thus positioning the crane.

[0041] Alternatively, the moving component 43 may be provided with a trolley structure 431; The two ends of the connecting beam 42 are respectively connected to the trolley structure 431, and the top of the side frame 41 is connected to the trolley structure 431.

[0042] The moving component 43 is provided with a trolley structure 431. The two ends of the connecting beam 42 are connected to the top of the side frame 41 through the trolley structure 431. The number of trolley structures 431 is determined according to the number of connecting beams 42. Each connecting beam 42 is provided with a trolley structure 431 at both the left and right ends, which can make the lateral movement of the cross-beam flatcar 4 more balanced and stable.

[0043] Alternatively, the side frame 41 may include: a horizontal frame plate 411 and a vertical frame plate 412; The horizontal frame plate 411 is fixed to the upper surface of the trolley structure 431; the upper end of the vertical frame plate 412 is connected to the horizontal frame plate 411, and the lower end of the vertical frame plate 412 is connected to the flatcar track beam 40.

[0044] The vertical plate 412 extends vertically, connecting the horizontal plate 411 and the flatcar track beam 40 into one unit. The horizontal plate 411 is horizontally oriented and connected to the connecting beam 42 via the trolley structure 431. In this embodiment, the horizontal plate 411 is fixed from top to bottom to the upper surface of the trolley structure 431. When the trolley structure 431 moves on the cross-bay running track 2, it is equivalent to suspending the vertical plate 412 and the flatcar track beam 40 below the cross-bay running track 2. The vertical plate 412 increases the distance between the flatcar track beam 40 and the connecting beam 42, which can reserve enough space for the crane. Thus, the lateral movement space of the cross-bay flatcar 4 and the longitudinal movement space of the crane are located below the hollow area 401 during the longitudinal movement of the crane on the flatcar receiving track 402, which can avoid the cross-bay flatcar 4 from causing any positional resistance to the crane below.

[0045] The side frame 41 of this design can be directly connected to the connecting beam 42; the side frame 41 can also be indirectly connected to the connecting beam 42, for example, through a moving component 43. The number of connecting beams 42 can be determined as needed; for example, in one embodiment, the cross-bay flatcar 4 can be equipped with a single connecting beam 42 to clear the space above the opening 403. This embodiment can accommodate cranes of any height, such as... Figure 9 ; In one embodiment, the number of connecting beams 42 is at least two, and the front and rear sides of the side frame 41 are respectively connected to the connecting beams 42. The number of connecting beams 42 is at least two, with at least one connecting beam 42 located above the opening 403 and at least one connecting beam 42 located above the bottom beam 44. Multiple connecting beams 42 can provide reinforcement.
