Description

Technical Field

[0001] The invention relates to the technical field of container loading and unloading, and in particular to a container spreader guiding device and a container spreader. Background Art

[0002] The container terminal is a hub for sea and land logistics transportation. The loading and unloading of containers at the terminal mainly relies on container bridge cranes. The bridge crane grabs the container through the lifting device to realize the lifting and loading and unloading of the container. The places where container ships store containers are divided into the cabin and the cabin. The gap between the cabin and the container is very small. The lifting device must be aligned with the narrow gap to enter the cabin to grab the container. However, due to the flexible nature of the wire rope, the lifting device will shake and deflect. At the same time, the ship will also sway due to factors such as tides and surges. During loading and unloading operations, the lifting device and the cabin will often collide. In severe cases, the lifting device will be stuck in the gap, causing machine damage and shutdown. Therefore, when the lifting device enters the cabin, the bridge crane driver needs to carefully control the lifting device and make multiple attempts to make the lifting device enter the cabin smoothly. In addition, as the ship becomes larger, the height of the bridge crane continues to increase, and the driver's line of sight cannot see the cabin gap in all directions. In order to ensure the smooth entry of the lifting device into the warehouse, one person needs to be arranged on the ship to command and monitor, which greatly reduces the operating efficiency of the bridge crane and there are also hidden dangers to the safety of the supervisor.

[0003] How to enable the container spreader guide device to enter and exit the cabin safely and efficiently, how to get rid of manual intervention, and how to achieve automatic and efficient loading and unloading of containers with an economically feasible solution are difficult problems that need to be solved urgently in this field.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-Figure 1 0, the container spreader guide device of the present invention comprises a connecting platform 10, a concave guide groove is provided on the connecting platform 10, the guide groove comprises a bottom wall 21 and a side wall, the angle between the bottom wall 21 and the side wall is an obtuse angle, and the side wall extends obliquely from bottom to top toward the top of the connecting platform 10; a lock pin box 30, a sliding mechanism is provided between the lock pin box 30 and the side wall, and the sliding mechanism is used to drive the lock pin box 30 to slide along the side wall; a limiting mechanism is provided between the bottom of the lock pin box 30 and the bottom wall 21, and the limiting mechanism is used to limit the lock pin box 30. A guide wheel 60 is provided at the bottom of the connecting platform 10, and the guide wheel 60 slides along the side wall of the cabin.

[0028] The container spreader guide device of the present invention can enter and exit the cabin conveniently, quickly, safely and efficiently, and can avoid the container spreader guide device from colliding with the cabin and preventing the container spreader guide device from being stuck in the cabin gap, so that the container in the cabin can be smoothly and efficiently grabbed and lifted, thereby improving the container loading and unloading efficiency and reducing safety hazards.

[0029] like Figure 2 As shown, before the container spreader guide device enters the cabin, the lock pin box 30 moves upward to be raised, and the lock pin box 30 moves to above the guide groove. Since the side wall of the guide groove extends obliquely from bottom to top toward the top end of the connecting platform 10, the size of the lock pin box 30 extending out of the guide groove is small, thereby reducing the overall length and width of the container spreader guide device, so that the container spreader guide device can smoothly, safely and efficiently enter the cabin gap, and can avoid the container spreader guide device from colliding with the cabin side wall and preventing the container spreader guide device from being stuck in the cabin gap.

[0030] During the process of the container spreader guide device moving downward into the cabin gap, the guide wheel 60 can roll along the cabin side wall, which can guide the downward movement of the container spreader guide device, so that the container spreader guide device can move downward smoothly and effectively, avoiding the container spreader guide device from colliding with the cabin side wall and avoiding the container spreader guide device from being stuck in the cabin gap.

[0031] like Figure 3As shown, after the container spreader guide device enters the cabin, the lock pin box 30 moves downward to the bottom wall 21, and the limiting mechanism can limit the lock pin box 30, which can prevent the lock pin box 30 from shaking and displacement, and ensure that the lock pin box 30 can stably and effectively grasp the container. The lock pin 37 at the bottom of the lock pin box 30 can be accurately inserted into the lock hole of the container to achieve accurate grasping of the container.

[0032] In this embodiment, the connecting platform 10 is in a rectangular parallelepiped shape as a whole, and includes a first vertical surface 11, a second vertical surface 12, a third vertical surface 13, and a fourth vertical surface 14 which are connected in sequence. The side between the first vertical surface 11 and the fourth vertical surface 14 is named as a first vertical side 15.

[0033] The guide groove extends from the second vertical surface 12 and the third vertical surface 13 toward the inside and top of the connecting platform 10, and the side walls of the guide groove extend obliquely from bottom to top (from the bottom wall upward) and toward the first vertical side 15, that is, the side walls of the guide groove extend obliquely from bottom to top toward the top end of the connecting platform 10.

[0034] Specifically, the side wall includes a first side wall 22, and second side walls 23 are symmetrically arranged on both sides of the first side wall 22. The angle between the first side wall 22 and the second side wall 23 is an obtuse angle, which can expand the volume of the guide groove, thereby providing the lock pin box 30 with a larger and sufficient accommodating space and minimizing the size of the lock pin box 30 extending out of the guide groove, so as to facilitate the container spreader guide device of the present invention to move down into the cabin fixing groove more smoothly and quickly.

[0035] The bottom wall 21 is arranged horizontally, the first side wall 22 and the second side wall 23 are arranged above the bottom wall 21, the angle between the first side wall 22 and the bottom wall 21 is an obtuse angle, and the angle between the second side wall 23 and the bottom wall 21 is an obtuse angle. Thus, the side wall can be inclined and extended from bottom to top toward the top end of the connecting platform 10, so that the volume above the guide groove can be increased, so that the lock pin box 30 can be given a larger and sufficient accommodating space, and the size of the lock pin box 30 extending out of the guide groove can be reduced as much as possible; when the lock pin box 30 moves up to the top of the guide groove, the size of the lock pin box 30 extending out of the guide groove is small, so that the overall length and width of the container spreader guide device can be reduced, so that the container spreader guide device of the present invention can be moved down to the cabin fixing groove more smoothly and quickly.

[0036] The sliding mechanism includes a first slide groove 24 arranged on the first side wall 22, and a first slide bar 25 is fixed in the first slide groove 24; the sliding mechanism also includes a second slide bar 31 protruding from the lock pin box 30, and a second slide groove 32 is provided on the second slide bar 31; the first slide bar 25 can be slidably fitted in the second slide groove 32, and the second slide bar 31 can be slidably fitted in the first slide groove 32.

[0037] Through the cooperation between the first slide bar 25 and the second slide groove 32, and the cooperation between the second slide bar 31 and the first slide groove 32, the lock pin box 30 can slide stably and effectively along the side wall, and can effectively prevent the lock pin box 30 from detaching from the side wall while sliding.

[0038] The first slide groove 24 is arranged on the first side wall 22 along the sliding direction of the lock pin box 30, and the first slide groove 24 is recessed on the surface of the first side wall 22; the first slide groove 24 can be in the shape of a rectangular parallelepiped, and an opening is arranged in the length direction of the first slide groove 24, so to speak, the first slide bar 25 is fixed in the first slide groove 24. The upper end of the first slide groove 24 is open, and the lower end of the first slide groove 24 extends to the bottom wall 21.

[0039] The first slide bar 25 is I-shaped and is fixed in the first slide groove 24 along the length direction of the first slide groove 24. The width of the first slide bar 25 is smaller than the width of the first slide groove 24, and there are gaps between both sides of the first slide bar 25 and the first slide groove 24, so as to provide accommodation space for the second slide bar 31, so that the second slide bar 31 can fit in the first slide groove 24.

[0040] The first slide bar 25 can be fixed in the first slide groove 32 by welding, or fixed in the first slide groove 32 by other methods commonly used in the art, which is not specifically limited here.

[0041] The second slide bar 31 is in a rectangular parallelepiped shape, and the second slide groove 32 is a T-shaped opening groove. The second slide groove 32 is arranged along the length direction of the second slide bar 31 .

[0042] The sliding mechanism further includes a guide groove 26 provided on the second side wall 23, and a guide block 33 provided on the lock pin box 30, and the guide block 33 can be slidably fitted in the guide groove 26. Through the cooperation between the guide block 33 and the guide groove 26, the sliding of the lock pin box 30 can be guided, thereby ensuring stable and effective sliding of the lock pin box 30.

[0043] The guide block 33 is T-shaped, and the guide groove 26 is a T-shaped open groove. The cooperation between the guide block 33 and the guide groove 26 can also limit the sliding of the lock pin box 30, thereby preventing the lock pin box 30 from detaching from the side wall while sliding. In this embodiment, there are two first slide grooves 24. A groove 27 is provided on the first side wall 22, and the groove 27 is arranged between the two first slide grooves 24.

[0044] An oil cylinder push rod 40 is installed in the groove 27, and the oil cylinder push rod 40 is used to drive the lock pin box 30 to slide up and down.

[0045] The groove 27 is arranged on the surface of the first side wall 22 , and the cylinder push rod 40 is arranged in the groove 27 , which can prevent the cylinder push rod 40 from protruding from the first side wall 22 and prevent the cylinder push rod 40 from hindering the sliding installation of the lock pin box 30 .

[0046] A protruding connecting block 34 is provided at the top of the lock pin box 30, and two parallel and spaced connecting plates 35 are provided at the bottom of the connecting block 34; a matching plate 42 is provided at the top of the push rod 41 of the cylinder push rod 40, and the matching plate 42 is matched and connected between the two connecting plates 35; thereby, the push rod 41 can be connected to the lock pin box 30, and the lock pin box 30 can be driven to slide up and down through the telescopic movement of the push rod 41.

[0047] The limiting mechanism includes a limiting column 28 arranged on the bottom wall 21 of the guide groove, and a limiting groove 36 arranged at the bottom of the lock pin box 30; when the lock pin box 30 slides downward to conflict with the bottom wall 21 of the guide groove, the limiting column 28 is engaged in the limiting groove 36. When the lock pin box 30 slides downward to conflict with the bottom wall 21, the lock pin box 30 is in the working position. At this time, the limiting column 28 is engaged in the limiting groove 36, which can limit the lock pin box 30, prevent the lock pin box 30 from shaking and displacing, so that the lock pin box 30 can be in a stable working position, and realize stable and effective container grabbing. The side wall of the connecting platform 10 is provided with a concave cross-shaped connecting groove 16, and the connecting groove 16 includes a vertical connecting groove and a horizontal connecting groove that are connected; the guide wheel 60 can be rotatably engaged in the vertical connecting groove, and a rotating shaft 61 is fixedly installed in the horizontal connecting groove, and the guide wheel 60 rotates around the rotating shaft 61.

[0048] Two blocking plates are connected to the side walls of the connecting platform 10 , and the two blocking plates are used to block the two ends of the opening of the transverse connecting groove so as to block the rotating shaft 61 .

[0049] Two springs 17 are installed in the transverse connecting groove. The two springs 17 are symmetrically installed at both ends of the transverse connecting groove. The axial direction of the spring 17 is perpendicular to the axial direction of the rotating shaft 61.

[0050] The two ends of the spring 17 are respectively fixed with a connecting plate 18 and a contact plate 19, which are perpendicular to the axial direction of the spring 17. The connecting plate 18 is fixed on the inner wall of the transverse connecting groove, and the contact plate 19 faces the rotating shaft 61 and contacts the rotating shaft 61.

[0051] When the guide wheel 60 contacts the side wall of the cabin, the guide wheel 60 can roll along the side wall of the cabin, and the side wall of the cabin can give the guide wheel 60 a resistance force, which is directed toward the inside of the connecting groove. Since the rotating shaft 61 is in conflict with the resistance plate 19, the spring 17 can give the guide wheel 60 an elastic resistance force. The direction of the elastic resistance force given by the spring 17 is opposite to the direction of the resistance force given by the side wall of the cabin, so that the guide wheel 60 and the rotating shaft 61 can be buffered and protected, avoiding the resistance force given by the side wall of the cabin from damaging the guide wheel 60 and the rotating shaft 61, and ensuring that the guide wheel 60 can effectively rotate around the rotating shaft 61.

[0052] The container spreader of the present invention comprises a spreader body, which comprises two telescopic beams 50 arranged in parallel and at intervals, and a connecting arm 51 is connected between the two telescopic beams 50. The container spreader of the present invention comprises four container spreader guide devices, which are respectively arranged at both ends of the two telescopic beams 50. The first vertical surface 11 of the connecting platform 10 is fixed to the end of the telescopic beam 50, and the end of the telescopic beam 50 is close to the first vertical side 15.

[0053] The telescopic beam 50 is provided with a telescopic mechanism, which can drive the telescopic beam 50 to telescope and move, thereby driving the connecting platform 10 and the lock pin box 30 to move (move along the length direction of the telescopic beam 50), so that the distance between the lock pin boxes 30 at both ends of the telescopic beam 50 can be adjusted so that the lock pin box 30 can be extended into the cabin.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents.
