Description

Technical Field

[0001] This utility model relates to the field of cross-shell hoisting devices, and in particular to a cross-shell hoisting device with a cross-span power extraction function. Background Technology

[0002] Currently, container handling at port terminals is mainly done by forklifts. Forklifts have short service lives and low efficiency, often requiring multiple trucks to wait for them to operate. Each forklift requires multiple people 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. Their operating area is relatively fixed and cannot be moved to other tracks. One reason for this is the issue of power supply stability. When a bridge crane is moved from one operating area to another, it needs to frequently switch power supplies. Power to the crane in one operating area must first be connected to the conveyor system before being connected to the other operating area. During the transfer, misalignment may occur, leading to the risk of power outages. Utility Model Content

[0003] The purpose of this invention is to propose a cross-bay type hoisting device with a cross-bay power collection function. The cross-bay flatcar moves through multiple loading and unloading areas. When the cross-bay flatcar moves to align with one of the loading and unloading areas, the crane sliding contact line and the cross-bay sliding contact line are connected by a horn-shaped docking structure. The large-diameter surface increases the docking area between the two, and the horn-shaped guide slope can reduce the impact of docking error on the longitudinal power collection contact, thereby ensuring the stability of the power supply to the bridge crane by the longitudinal current collector before and after the cross-bay.

[0004] To achieve this objective, the present invention adopts the following technical solution: A cross-bay hoisting device with a cross-bay power extraction function includes: a crane running rail, a cross-bay running rail, a bridge crane, a cross-bay flatcar, and a power extraction mechanism; Several crane running tracks are arranged longitudinally, with adjacent crane running tracks spaced apart to form loading and unloading areas; the cross-shell running track passes laterally through several loading and unloading areas; The bridge crane moves longitudinally along the crane running rails on both sides of the loading and unloading area; the cross-bay flatcar is provided with a longitudinal flatcar receiving rail, and the cross-bay flatcar moves laterally along the cross-bay running rail, allowing the cross-bay flatcar to pass laterally through multiple loading and unloading areas; when the flatcar receiving rail moves to be longitudinally aligned with the crane running rail, the bridge crane moves between the crane running rail and the flatcar receiving rail, allowing the bridge crane to leave or enter the loading and unloading area; after the bridge crane enters the cross-bay flatcar, the cross-bay flatcar drives the bridge crane to move laterally, allowing the bridge crane to move to be longitudinally aligned with any one of the loading and unloading areas; The power collection mechanism includes: a crane conductor rail, a cross-section vehicle conductor rail, and a longitudinal current collector; The crane conductor rail extends along the length of the crane running track and is positioned beside the crane running track; the crosscar conductor rail extends along the length of the flatcar receiving track and is positioned beside the flatcar receiving track; both the crane conductor rail and the crosscar conductor rail are provided with horn-shaped connecting structures at their ends. The outer diameter of the horn-shaped connecting structure gradually increases towards the end, forming a large-diameter surface at the end with the largest outer diameter and a small-diameter surface at the end with the smallest outer diameter. The sides between the surfaces form a horn-shaped guide slope; when the cross-bay flatcar moves laterally to align with the loading and unloading area longitudinally, the large-diameter surfaces of the crane sliding contact line and the cross-bay car sliding contact line are longitudinally aligned and close together; the longitudinal current collector moves synchronously with the bridge crane; the longitudinal current collector is provided with a longitudinal power-taking contact, which moves between the crane sliding contact line and the cross-bay car sliding contact line, and the longitudinal power-taking contact elastically contacts the crane sliding contact line or the cross-bay car sliding contact line, so that the crane sliding contact line or the cross-bay car sliding contact line is electrically connected to the bridge crane.

[0005] Optimally, the longitudinal current collector is provided with a pair of longitudinally arranged longitudinal power-taking contacts.

[0006] Optimally, the longitudinal power-taking contact contacts the bottom of the crane conductor rail or the bottom of the cross-beam conductor rail from bottom to top.

[0007] Optimally, when the major diameter surfaces of the crane conductor rail and the cross-beam conductor rail are in contact, the major diameter surfaces of the two are spaced apart to form a conductor rail gap.

[0008] Optimally, it may also include: an anchoring device; The anchoring device includes: an anchor rod, an anchor seat, and an anchoring push rod actuator; The output end of the anchoring push rod driver is connected to the anchoring rod, and is used to drive the anchoring rod to move to a position limited to or disengage from the anchor seat; One of the anchor rod and the anchor seat is disposed on the bridge crane, and the other is disposed on the cross-shell flatcar. When the anchor rod moves to its limit position at the anchor seat, the bridge crane is limited to the cross-shell flatcar; and / or one of the anchor rod and the anchor seat is disposed on the cross-shell flatcar, and the other is disposed on the cross-shell running track. When the anchor rod moves to its limit position at the anchor seat, the cross-shell flatcar is limited to the cross-shell running track.

[0009] Optimally, it may also include: windproof components; The windproof component includes: a windproof actuator and a windproof iron wedge; The output end of the windproof driver is connected to the windproof wedge and is used to drive the windproof wedge to move so that the windproof wedge moves closer to or further away from the flatcar receiving track and / or the cross-shell running track. When the windproof wedge approaches the flatcar receiving track, the bridge crane moves to abut against the windproof wedge, which restricts the bridge crane from moving on the flatcar receiving track; and / or when the windproof wedge approaches the transshipment running track, the transshipment flatcar moves to abut against the windproof wedge, which restricts the transshipment flatcar from moving on the transshipment running track.

[0010] Optimally, it may also include: a track locking device; The track locking device includes: a track locking lever, a locking seat, and a track locking push rod driver; One of the track locking rod and the locking seat is disposed on the crane running track, and the other is disposed on the flatcar receiving track; the output end of the track locking push rod driver is connected to the track locking rod, and is used to drive the track locking rod to move to a position limited to or disengage from the locking seat; before the bridge crane enters or disengages from the crane running track, the track locking rod moves to a position limited to the locking seat, thereby fixing the crane running track and the flatcar receiving track.

[0011] Alternatively, the power collection mechanism may further include: a sliding contact line for the transverse flatcar and a lateral current collector; The sliding contact line of the cross-shell flatcar extends along the length of the cross-shell running track and is located beside the cross-shell running track; the lateral current collector is located on the cross-shell flatcar and is provided with a lateral power-taking contact; the lateral power-taking contact contacts the sliding contact line of the cross-shell flatcar, and the sliding contact line of the cross-shell flatcar is electrically connected to the cross-shell flatcar.

[0012] Alternatively, the lateral current collector can be electrically connected to the cross-section sliding contact line.

[0013] Compared with the prior art, one of the above technical solutions has the following beneficial effects: This solution provides a cross-bay type hoisting device with a cross-bay power collection function. The cross-bay flatcar moves through multiple loading and unloading areas. When the cross-bay flatcar moves to align with one of the loading and unloading areas, the crane sliding contact line and the cross-bay car sliding contact line are connected by a horn-shaped docking structure. The large-diameter surface increases the docking area between the two, and the horn-shaped guide slope can reduce the impact of docking errors on the longitudinal power collection contacts, thereby ensuring the power supply stability of the longitudinal current collector to the bridge crane before and after the cross-bay. This solves the risk of power outage caused by misalignment of the crane sliding contact line and the cross-bay car sliding contact line. Attached Figure Description

[0018] like Figure 1-9 A cross-shell type hoisting device with cross-span power extraction function includes: a crane running rail 1, a cross-shell running rail 2, a bridge crane 3, a cross-shell flatcar 4, and a power extraction mechanism 91; 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-shell flatcar 4 is provided with a longitudinal flatcar receiving track 40, and the cross-shell flatcar 4 moves laterally along the cross-shell running track 2, so that the cross-shell flatcar 4 passes laterally through multiple loading and unloading areas 101; when the flatcar receiving track 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 receiving track 40, so that the bridge crane 3 leaves or enters the loading and unloading area 101; after the bridge crane 3 enters the cross-shell flatcar 4, the cross-shell 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; The power collection mechanism 91 includes: a crane sliding contact line 911, a cross-car sliding contact line 912, and a longitudinal current collector 913; The crane conductor rail 911 extends along the length of the crane running track 1 and is located beside the crane running track 1; the crosscar conductor rail 912 extends along the length of the flatcar receiving track 40 and is located beside the flatcar receiving track 40; the crane conductor rail 911 and the crosscar conductor rail 912 are respectively provided with horn-shaped docking structures 910 at their ends, the outer diameter of the horn-shaped docking structure 910 gradually increases towards the end, so that the horn-shaped docking structure 910 forms a large-diameter surface 9101 at the end with the largest outer diameter and a small-diameter surface 9102 at the end with the smallest outer diameter, and the area between the large-diameter surface 9101 and the small-diameter surface 9102 is... A horn-shaped guide slope 9103 is formed on the side; when the cross-beam flatcar 4 moves laterally to align with the loading and unloading area 101 longitudinally, the large-diameter surfaces 9101 of the crane sliding contact line 911 and the cross-beam flatcar sliding contact line 912 are longitudinally aligned and close together; the longitudinal current collector 913 moves synchronously with the bridge crane 3; the longitudinal current collector 913 is provided with a longitudinal power-taking contact 914, which moves between the crane sliding contact line 911 and the cross-beam flatcar sliding contact line 912, and the longitudinal power-taking contact 914 elastically contacts the crane sliding contact line 911 or the cross-beam flatcar sliding contact line 912, so that the crane sliding contact line 911 or the cross-beam flatcar sliding contact line 912 is electrically connected to the bridge crane 3.

[0019] This solution provides a cross-bay type hoisting device with a cross-bay power supply function. The cross-bay flatcar 4 moves through multiple loading and unloading areas 101. When the cross-bay flatcar 4 moves to align with one of the loading and unloading areas 101, the crane sliding contact line 911 and the cross-bay car sliding contact line 912 are connected through a horn-shaped docking structure 910. The large-diameter surface 9101 increases the docking area between the two, and the horn-shaped guide slope 9103 can reduce the impact of docking error on the longitudinal power supply contact 914, thereby ensuring the power supply stability of the longitudinal current collector 913 to the bridge crane 3 before and after the cross-bay. This solves the risk of power outage due to misalignment of the crane sliding contact line 911 and the cross-bay car sliding contact line 912.

[0020] 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 receiving track 40. When the cross-bay flatcar 4 is longitudinally aligned with the loading and unloading area 101, the flatcar receiving track 40 is longitudinally aligned with the crane running track 1, and the flatcar receiving track 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 101. 01, and seamlessly transfer to the flatcar receiving track 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 receiving track 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.

[0021] The crane conductor rail 911 extends along the length of the crane running track 1, and the crosscar conductor rail 912 extends along the length of the flatcar receiving track 40. The longitudinal current collector 913 moves synchronously with the bridge crane 3. In one embodiment, the bridge crane 3 and the longitudinal current collector 913 are connected synchronously, and the bridge crane 3 directly drives the longitudinal current collector 913. In another embodiment, the longitudinal current collector 913 may be driven directly by a separately installed drive mechanism. The known longitudinal current collector 913 generally has a resiliently adjustable longitudinal power-taking contact 914. The longitudinal power-taking contact 914 resiliently contacts and moves along the crane conductor rail 911 and the crosscar conductor rail 912, for example, by means of a spring. The power-taking contact 914 presses against the crane conductor rail 911 or the cross-section carriage conductor rail 912; the elastic contact of the longitudinal power-taking contact 914 can provide stable contact pressure, thereby maintaining contact with the crane conductor rail 911 or the cross-section carriage conductor rail 912, and adaptively adjusting the position when resistance occurs; when the longitudinal power-taking contact 914 contacts the crane conductor rail 911, the bridge crane 3 is electrically connected to the crane conductor rail 911, and the crane conductor rail 911 supplies power to the bridge crane 3 through the longitudinal current collector 913; when the longitudinal power-taking contact 914 contacts the cross-section carriage conductor rail 912, the bridge crane 3 is electrically connected to the cross-section carriage conductor rail 912, and the cross-section carriage conductor rail 912 supplies power to the bridge crane 3 through the longitudinal current collector 913; When the flatbed crane 4 needs to receive the bridge crane 3 at the end of a loading / unloading area 101, the flatbed crane 4 moves to align with the loading / unloading area 101, the crane running track 1 is longitudinally aligned with the flatbed crane receiving track 40, and the crane sliding contact line 911 and the flatbed crane sliding contact line 912 are longitudinally connected. Both the crane sliding contact line 911 and the flatbed crane sliding contact line 912 have horn-shaped docking structures 910 at their respective opposite ends. The outer diameter of the horn-shaped docking structure 910 gradually increases towards the ends, resulting in a large-diameter surface 9101 at the end with the largest outer diameter and a small-diameter surface 9102 at the end with the smallest outer diameter. The two are connected through the large-diameter surface 9101 of the horn-shaped docking structure 910 (the docking method can be close together or in contact). Thus, when the crane sliding contact line 911 and the flatbed crane sliding contact line 912 are connected... The longitudinal power take-up contact 914 is connected to the crane sliding contact line 911 or the cross-beam flatcar sliding contact line 912 via the largest diameter surface 9101. When the bridge crane 3 moves to the cross-beam flatcar 4, the crane sliding contact line 911 supplies power to the bridge crane 3. The longitudinal power take-up contact 914 moves from the small diameter surface 9102 of the crane sliding contact line 911 to the large diameter surface 9101, and is guided by the horn guide slope 9103 to move. The longitudinal power take-up contact 914 then crosses the large diameter surface 9101 of the cross-beam flatcar sliding contact line 912, and is guided by the horn guide slope 9103 to the small diameter surface 9102 of the cross-beam flatcar sliding contact line 912 until the longitudinal current collector 913 is completely transferred to the cross-beam flatcar 4. At this time, the cross-beam flatcar sliding contact line 912 can supply power to the bridge crane 3. Thus, during the crossing of the gantry crane 3, the crane 3 can still operate with power, ensuring uninterrupted power supply before and after lateral movement, and enabling normal control of the crane 3 during the crossing. In summary, this solution ensures the stability of power supply to the crane 3 by the longitudinal current collector 913 before and after the crossing, and solves the risk of power outage due to misalignment between the crane's sliding contact line 911 and the crossing vehicle's sliding contact line 912.

[0022] As is generally known, the longitudinal current collector 913 mainly includes a mechanical tension device and a longitudinal power-taking contact 914. The mechanical tension device provides stable contact pressure through a spring, ensuring that there is always just the right contact force between the longitudinal power-taking contact 914 and the crane sliding contact line 911 or the cross-section trolley sliding contact line 912. When the bridge crane 3 is running, the longitudinal current collector 913 moves synchronously with the bridge crane 3, and the longitudinal power-taking contact 914 maintains sliding contact with the crane sliding contact line 911 or the cross-section trolley sliding contact line 912. Electrical energy is transmitted through the path of "longitudinal power-taking contact 914 → crane sliding contact line 911 or cross-section trolley sliding contact line 912 → bridge crane 3", so that the bridge crane 3 can continuously obtain power during the movement.

[0023] Alternatively, the longitudinal current collector 913 may be provided with a pair of longitudinally arranged longitudinal power-taking contacts 914.

[0024] The longitudinal current collector 913 preferably has a pair of longitudinal power-taking contacts 914, that is, at least two longitudinal power-taking contacts 914, which are arranged longitudinally, that is, along the direction of the crane sliding contact line 911 and the cross-car sliding contact line 912. The flatcar receiving rail 40 is connected to the front of the crane running rail 1, and the two longitudinal power-taking contacts 914 are respectively engaged with the crane sliding contact line 911. The crane sliding contact line 911 supplies power to the bridge crane 3. When any one of the longitudinal power-taking contacts 914 fails, the other longitudinal power-taking contact 914 can continue to supply power. When the flatcar receiving rail 40 is connected to the crane running rail 1, the longitudinal current collector 913 moves with the bridge crane 3. The front longitudinal power-taking contact 914 moves to the cross-car sliding contact line 912, and the rear longitudinal power-taking contact 914 is located on the crane. The sliding contact line 911 allows both the crane sliding contact line 911 and the cross-bay car sliding contact line 912 to supply power to the bridge crane 3. This ensures that the bridge crane 3 remains energized when entering and exiting the cross-bay car 4, thus maintaining the movement of the bridge crane 3 and preventing power outages that could prevent it from moving. When the bridge crane 3 enters the cross-bay car 4, two longitudinal power-taking contacts 914 are respectively engaged with the cross-bay car sliding contact line 912, which supplies power to the bridge crane 3. If either longitudinal power-taking contact 914 fails, the other longitudinal power-taking contact 914 can continue to supply power. Thus, the bridge crane 3 remains energized on both the crane running track 1 and the cross-bay car 4, ensuring the stability of the power supply from the longitudinal current collector 913 to the bridge crane 3 before and after the cross-bay.

[0025] Optimally, the longitudinal power-taking contact 914 contacts the bottom of the crane conductor rail 911 or the bottom of the cross-beam carriage conductor rail 912 from bottom to top.

[0026] Since the cross-bay running track 2 extends laterally, the cross-bay flatcar 4 moves laterally along the cross-bay running track 2. The cross-bay running track 2 moves laterally until the crane sliding contact line 911 and the cross-bay car sliding contact line 912 are aligned. Therefore, the error between the crane sliding contact line 911 and the cross-bay car sliding contact line 912 is mainly concentrated in their lateral spacing. The height position between the cross-bay flatcar 4 and the cross-bay car sliding contact line 912 of the cross-bay running track 2 and the crane sliding contact line 911 of the crane running track 1 remains basically unchanged. The longitudinal power taking contact 914 contacts the bottom of the crane sliding contact line 911 or the bottom of the cross-bay car sliding contact line 912 from bottom to top. The longitudinal power taking contact 914 contacts both with the smallest error, which can improve the smoothness of the longitudinal power taking contact 914 during the transition between the crane sliding contact line 911 and the cross-bay car sliding contact line 912 and avoid the positional resistance of the error area from affecting the normal passage of the longitudinal power taking contact 914.

[0027] When the large diameter surfaces 9101 of the crane conductor rail 911 and the cross-beam conductor rail 912 are joined, the large diameter surfaces 9101 of the two are separated to form a conductor rail gap 9104.

[0028] The sliding contact line gap 9104 is located between the large diameter surfaces 9101 of the crane sliding contact line 911 and the crossbeam sliding contact line 912. The size of the sliding contact line gap 9104 can be determined according to the actual situation, for example, 1-10mm. The sliding contact line gap 9104 can appropriately increase the longitudinal distance between the two, which can ensure that when the crossbeam flatcar 4 moves laterally, the crossbeam flatcar 4's crossbeam sliding contact line 912 will not contact the crane sliding contact line 911 of multiple loading and unloading areas 101, thereby maintaining the smooth movement of the crossbeam flatcar 4.

[0029] 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.

[0030] 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. 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.

[0031] 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 driver 61 is connected to the windproof wedge 62 and is used to drive the windproof wedge 62 to move so that the windproof wedge 62 moves closer to or further away from the flatcar receiving track 40 and / or the cross-shell running track 2. When the windproof wedge 62 approaches the flatcar receiving track 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 receiving track 40; and / or when the windproof wedge 62 approaches the cross-shell running track 2, the cross-shell flatcar 4 moves to abut against the windproof wedge 62, and the windproof wedge 62 restricts the cross-shell flatcar 4 from moving on the cross-shell running track 2.

[0032] This solution also includes a windproof component 6 installed at the flatcar receiving track 40 or the cross-bay running track 2. Its windproof actuator 61 drives the windproof wedge 62 to move closer to or further away from the flatcar receiving track 4 (or cross-bay running track 2). When the windproof wedge 62 moves closer to the flatcar receiving track 40 (or cross-bay running track 2), it is within the movement range of the bridge crane 3 (or cross-bay flatcar 4). The bridge crane 3 (or cross-bay flatcar 4) will abut against the windproof wedge 62, and the windproof wedge 62 utilizes… Friction or obstruction fixes the bridge crane 3 (or the cross-bay flatcar 4), thereby limiting the bridge crane 3 (or the cross-bay flatcar 4) to the flatcar receiving track 40 (or the cross-bay running track 2), preventing the bridge crane 3 (or the cross-bay flatcar 4) from being blown by the wind; at the same time, combined with the anchoring device 5 between the bridge crane 3 and the cross-bay flatcar 4, the anchoring device 5 and the windproof component 6 together limit the bridge crane 3 (or the cross-bay flatcar 4), forming a double locking effect on the bridge crane 3 and the cross-bay flatcar 4.

[0033] 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 receiving rail 40, so as to restrict the movement of the bridge crane 3 at the end of its movement.

[0034] 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 receiving track 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 at 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, thereby fixing the crane running track 1 and the flatcar receiving track 40.

[0035] A track locking device 7 can be installed between the crane running track 1 and the flatcar receiving track 40. The track locking device 7 is used to lock the crane running track 1 and the flatcar receiving track 40, thereby improving the movement stability of the crane when entering and exiting the cross-bay 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-bay flatcar 4, or when the bridge crane 3 is about to disengage from the cross-bay 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 receiving track 40 are fixed to each other, thereby preventing the crane running track 1 or the flatcar receiving track 40 from undergoing unexpected displacement when the bridge crane 3 enters and exits the cross-bay flatcar 4, and improving the stability of the bridge crane 3 entering the cross-bay flatcar 4.

[0036] 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.

[0037] Alternatively, the power collection mechanism 91 may further include: a sliding contact line 915 for the transverse flatcar and a transverse current collector 916; The sliding contact line 915 of the cross-shell flatcar extends along the length of the cross-shell running track 2 and is disposed on the side of the cross-shell running track 2; the transverse current collector 916 is disposed on the cross-shell flatcar 4, and the transverse current collector 916 is provided with a transverse power taking contact 917; the transverse power taking contact 917 contacts the sliding contact line 915 of the cross-shell flatcar, and the sliding contact line 915 of the cross-shell flatcar is electrically connected to the cross-shell flatcar 4.

[0038] The sliding contact line 915 of the cross-beam flatcar extends along the length of the cross-beam running track 2. The transverse current collector 916 moves laterally with the cross-beam flatcar 4, driving the transverse power take-up contact 917 to move on the sliding contact line 915 of the cross-beam flatcar, thereby maintaining the electrical connection between the cross-beam flatcar 4 and the sliding contact line 915 of the cross-beam flatcar, so that the cross-beam flatcar 4 can maintain the energized state both before and after the cross-beam.

[0039] In some embodiments, the cross-beam flatcar 4's cross-beam sliding contact line 912 is powered by a power source other than the cross-beam flatcar running contact line 915, for example, the cross-beam flatcar 4 is equipped with a battery to power the cross-beam sliding contact line 912; in a preferred embodiment, the lateral current collector 916 is electrically connected to the cross-beam sliding contact line 912.

[0040] The lateral current collector 916 is directly or indirectly electrically connected to the sliding contact line 912 of the cross-beam car. Since the lateral power taking contact 917 of the lateral current collector 916 is kept in contact with the running sliding contact line 915 of the cross-beam car, the running sliding contact line 915 of the cross-beam car supplies power to the cross-beam car 4 through the lateral current collector 916. The cross-beam car sliding contact line 912 is located in the cross-beam car 4, and the lateral current collector 916 can also supply power to the cross-beam car sliding contact line 912. The cross-beam car sliding contact line 912 does not need to be connected to other power sources, but is powered by the running sliding contact line 915 of the cross-beam car, thereby simplifying the power supply structure of the cross-beam car sliding contact line 912 and making the structure of the cross-beam car 4 more compact.
