Description

Technical Field

[0001] This utility model belongs to the field of crane technology, and in particular relates to a container rotating crane. Background Technology

[0002] like Figure 7 The diagram shows the structure of an existing container. Specifically, existing containers usually have corner fittings 20 installed at the four corners of the container 19. The corner fittings 20 are shell structures with cavities and have lifting holes to facilitate the lifting and handling of the container 19 using a crane.

[0003] Currently, when lifting and moving container 19, it is sometimes necessary to rotate container 19 by a certain angle so that it is parallel to the side before placing it. However, existing cranes usually have a rotating mechanism in the middle of the lifting mechanism that can drive container 19 to rotate. In this way, when the crane lifts and rotates container 19, it is necessary to move container 19 horizontally to the side position by the crane's trolley. The operation is relatively cumbersome. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a container rotating crane to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A container rotating crane includes a frame, with horizontally distributed arc-shaped tracks mounted on the top of the frame. End beams capable of moving along the arc-shaped tracks are mounted on the arc-shaped tracks. Horizontally distributed main load-bearing beams are mounted on the inner side of the end beams. The end of the main load-bearing beams furthest from the end beams is rotatably connected to the frame via vertically distributed connecting shafts. A lifting mechanism is mounted on the main load-bearing beams, and a lifting mechanism for lifting containers is attached to the lifting mechanism, which is located below the main load-bearing beams.

[0007] Furthermore, both ends of the end beam are bent inward, and both ends of the end beam are equipped with a trolley running mechanism that can travel along the arc-shaped track. The two sets of trolley running mechanisms are symmetrically arranged on both sides of the main beam, and the axial lines of the traveling wheel axles of the trolley running mechanisms all point to the center of the arc-shaped track.

[0008] Furthermore, the angle between the two ends of the arc-shaped track and the center of the arc-shaped track is greater than 90 degrees.

[0009] Furthermore, the lifting mechanism is a four-point synchronous lifting mechanism.

[0010] Furthermore, the hoisting mechanism includes a hanger connected to the lifting mechanism. The hanger is located below and parallel to the main beam, and two opposing first connecting beams are installed on the hanger. The first connecting beams are perpendicular to the main beam in the horizontal direction. Each first connecting beam has vertically distributed rotating shafts rotatably connected to both ends. The two rotating shafts on the same first connecting beam are connected to a drive motor mounted on the first connecting beam. The bottom end of each rotating shaft passes through the first connecting beam and is fixedly connected to a locking tongue. Both sides of the locking tongue extend horizontally outside the rotating shaft.

[0011] Furthermore, a second connecting beam is installed on the hanger, which is parallel to the first connecting beam. Both ends of the second connecting beam are equipped with vertically distributed sleeves. Movable rods are slidably connected inside each sleeve. The bottom end of each movable rod is located outside the second connecting beam and is equipped with a pressure block. A spring is sleeved on the movable rod located between the pressure block and the sleeve.

[0012] Furthermore, the frame is provided with a load-bearing beam that matches the shape of the arc-shaped track. Several vertically distributed L-shaped supports are installed between the load-bearing beam and the top of the frame. The L-shaped supports are distributed along the arc length of the load-bearing beam, and the arc-shaped track is installed on the top surface of the load-bearing beam.

[0013] Furthermore, a vertically distributed first guardrail is installed on the outer side of the load-bearing beam, and a support platform is installed at one end of the load-bearing beam. An inclined ladder is installed between the support platform and the bottom of the frame.

[0014] Furthermore, a pedestrian walkway is installed on one side of the main beam, parallel to the main beam, and a vertically distributed second guardrail is installed on the pedestrian walkway.

[0015] Furthermore, vertically distributed stop plates are installed on the load-bearing beams at both ends of the arc-shaped track, and polyurethane buffers are installed at both ends of the end beams.

[0016] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0017] When using this invention, after the container is lifted by the hoisting mechanism, the container can be raised a certain distance by the lifting mechanism. Then, when the end beam moves along the arc-shaped track, since the end of the main beam away from the end beam is rotatably connected to the frame, the container can be moved to the side position while being rotated at a certain angle. In other words, compared with the prior art, using this invention, when it is necessary to rotate the container at a certain angle and place it to the side, the operation is simple and easy to carry out.

[0026] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 6 As shown, this utility model provides a container rotating crane for lifting and rotating containers such as... Figure 7The container 19 shown; this utility model includes a frame 6, specifically, the frame 6 includes a horizontally arranged support frame 61, with several vertically distributed columns 62 fixedly connected to both sides of the bottom of the support frame 61, and a reinforcing beam 63 fixedly connected between every two adjacent columns 62 on the same side of the support frame 61 to ensure the structural stability of the frame 6. The position of the frame 6 can be fixed during use; a horizontally distributed arc-shaped track 1 is installed at the top inside the frame 6, and an end beam 2 capable of moving along the arc-shaped track 1 is installed on the arc-shaped track 1. A horizontally distributed main load-bearing beam 5 is installed on the inner side of the end beam 2. The end of the main load-bearing beam 5 away from the end beam 2 is rotatably connected to the frame 6 through a vertically distributed connecting shaft 7. Specifically, the top end of the connecting shaft 7 is installed on the frame 6, and the bottom end of the connecting shaft 7 is connected to the main load-bearing beam 5 through a slewing bearing 8 to realize the rotatable connection between the main load-bearing beam 5 and the frame 6. A lifting mechanism 4 is installed on the main load-bearing beam 5, and a lifting mechanism 3 for lifting the container 19 is attached to the lifting mechanism 4. The lifting mechanism 4 can drive the lifting mechanism 3 to lift and lower. The lifting mechanism 3 is located below the main load-bearing beam 5.

[0028] Specifically, before hoisting container 19, mobile equipment such as a handling vehicle can be used to move container 19 to a position below hoisting mechanism 3, and make container 19 parallel to the main supporting beam 5. Then, after hoisting container 19 is lifted by hoisting mechanism 3, container 19 can be raised a certain distance by lifting mechanism 4. At this time, when end beam 2 moves along arc track 1, since the end of main supporting beam 5 away from end beam 2 is rotatably connected to frame 6, container 19 can be moved to the side position at the same time when it is rotated a certain degree. In other words, compared with the prior art, using this utility model, when it is necessary to rotate container 19 to a certain angle and place it to the side, the operation method is simple and easy to operate.

[0029] The specific configuration for enabling end beam 2 to move along the arc-shaped track 1 is as follows: Figures 1 to 3 As shown, both ends of the end beam 2 are bent inward, and both ends of the end beam 2 are equipped with a trolley traveling mechanism 9 that can travel along the arc-shaped track 1. Specifically, the trolley traveling mechanism 9 includes traveling wheels, traveling motors, traveling wheel axles, etc. The two sets of trolley traveling mechanisms 9 are symmetrically arranged on both sides of the main beam 5, and the axial lines of the traveling wheel axles of the trolley traveling mechanism 9 all point to the center of the arc-shaped track 1. In this way, when the trolley traveling mechanism 9 is started, the end beam 2 can be moved along the arc-shaped track 1, thereby allowing the main beam 5 to rotate around the connecting shaft 7, so as to drive the container 19 to rotate.

[0030] Furthermore, the angle between the two ends of the arc-shaped track 1 and the center of the arc-shaped track 1 is greater than 90 degrees, so that during use, such as Figure 1As shown, when the end of the main beam 5 near the end beam 2 is located at the end of the arc-shaped track 1, after the container 19 is lifted by the hoisting mechanism 3, when the end beam 2 moves along the arc-shaped track 1, it can be ensured that the present invention can drive the container 19 to rotate 90 degrees and be placed to the side.

[0031] The specific configuration of the lifting mechanism 4 is as follows: Figures 1 to 3 As shown, the lifting mechanism 4 is a four-point synchronous lifting mechanism. Specifically, the lifting mechanism 4 is existing technology, which includes a drum, a lifting motor, a brake, a wire rope, and four fixed pulley blocks. The four fixed pulley blocks are located at the four corners of the main beam 5. In this way, the swing amplitude of the lifting mechanism 3 can be reduced and the operation can be stable when lifting through four points.

[0032] The specific setup of hoisting mechanism 3 is as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the hoisting mechanism 3 includes a gantry 31 connected to the lifting mechanism 4. Specifically, pulley groups are installed at the four corners of the gantry 31, which are opposite to the fixed pulley groups. The pulley groups and the fixed pulley groups are connected by steel wire ropes. The gantry 31 is located below the main supporting beam 5 and is parallel to the main supporting beam 5. Two opposing first connecting beams 32 are installed on the gantry 31. The first connecting beams 32 are perpendicular to the main supporting beam 5 in the horizontal direction. Each end of the first connecting beam 32 is rotatably connected to a vertically distributed rotating shaft 33. The two rotating shafts 33 on the same first connecting beam 32 are connected together by a drive motor 34 installed on the first connecting beam 32. Specifically, the first connecting beam 32 is a box structure with a cavity, which can be used to install the transmission mechanism between the rotating shaft 33 and the output shaft of the drive motor 34.

[0033] In addition, each pivot 33 has a locking tongue 35 fixedly connected to its bottom end after passing through the first connecting beam 32. Both sides of the locking tongue 35 extend horizontally outside the pivot 33. Specifically, the four pivots 33 are respectively positioned opposite the corner fittings 20 located at the four corners of the container 19. In use, when the lifting mechanism 4 is used to lower the hoisting mechanism 3, the locking tongue 35 can pass through the hoisting hole on the top surface of the corner fitting 20 and be located inside the corner fitting 20. Then, the driving motor 34 drives the locking tongue 35 to rotate 90 degrees, so that the extended sides of the locking tongue 35 are located outside the hoisting hole on the top surface of the corner fitting 20. At this time, when the lifting mechanism 4 drives the hoisting mechanism 3 to rise, the container 19 can be lifted when the locking tongue 35 abuts against the inner top surface of the corner fitting 20. That is, the hoisting hole on the top surface of the corner fitting 20 is a rectangular hole, and the distance between the two extended sides of the locking tongue 35 is less than the length of the rectangular hole and greater than the width of the rectangular hole.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a second connecting beam 36 is installed on the hanger 31, parallel to the first connecting beam 32. Vertically distributed sleeves 37 are installed at both ends of the second connecting beam 36. A movable rod 38 is slidably connected inside each sleeve 37. Specifically, a limit ring is coaxially installed at the bottom of the sleeve 37, and a limit plate is coaxially installed at the top of the movable rod 38 to prevent it from slipping off the sleeve 37. The bottom end of each movable rod 38 is located outside the second connecting beam 36 and is fitted with a pressure block 39, positioned between the pressure block 39 and the sleeve 37. A spring 30 is fitted on the movable rod 38. Specifically, during use, when the lifting mechanism 4 is used to lower the hoisting mechanism 3, the pressure block 39 can abut against the top surface of the container 19. Then, as the hoisting mechanism 3 continues to descend, the movable rod 38 can slide along the sleeve 37 and compress the spring 30. Then, when the locking tongue 35 is located inside the corner piece 20, when the lifting mechanism 4 is used to drive the hoisting mechanism 3 to rise, the spring 30 rebounds and the pressure block 39 presses against the container 19 to improve the stability of the container 19 on the hoisting mechanism 3.

[0035] The specific installation method of the arc-shaped track 1 is as follows: Figures 1 to 3 As shown, a load-bearing beam 10 adapted to the shape of the arc-shaped track 1 is provided inside the frame 6. Several vertically distributed L-shaped supports 11 are installed between the load-bearing beam 10 and the top of the frame 6. The L-shaped supports 11 are distributed along the arc length of the load-bearing beam 10. Specifically, the L-shaped support 11 includes a vertical beam and a horizontal beam. The top of the vertical beam of the L-shaped support 11 is fixedly installed on the frame 6, while the horizontal beam of the L-shaped support 11 is located below the load-bearing beam 10 to support the load-bearing beam 10, thus ensuring the structural stability of the load-bearing beam 10. The arc-shaped track 1 is installed on the top surface of the load-bearing beam 10. Specifically, the arc-shaped track 1 can be set on the inner side of the load-bearing beam 10.

[0036] Furthermore, such as Figures 1 to 3 As shown, a vertically distributed first guardrail 12 is installed on the outer side of the load-bearing beam 10, and a support platform 13 is installed at one end of the load-bearing beam 10. An inclined ladder 14 is installed between the support platform 13 and the bottom of the frame 6. Specifically, in use, maintenance personnel can climb the support platform 13 via the ladder 14 and then walk along the load-bearing beam 10, which facilitates the maintenance of the arc-shaped track 1, end beam 2, trolley running mechanism 9, etc. The first guardrail 12 can prevent maintenance personnel from falling from the load-bearing beam 10.

[0037] Furthermore, such as Figures 1 to 3As shown, a personnel walkway 15 is installed on one side of the main beam 5, which is parallel to the main beam 5. Specifically, during use, maintenance personnel can enter the personnel walkway 15 through the load-bearing beam 10, which facilitates the maintenance of the main beam 5, the lifting mechanism 4, and the connection between the main beam 5 and the frame 6. In addition, a vertically distributed second guardrail 16 is installed on the personnel walkway 15 to prevent maintenance personnel from falling off the personnel walkway 15.

[0038] Furthermore, such as Figures 1 to 3 As shown, vertically distributed stop plates 17 are installed on the load-bearing beams 10 at both ends of the arc-shaped track 1. Specifically, when the end beam 2 moves along the arc-shaped track 1, the stop plates 17 can prevent the end beam 2 from running over the range, thereby preventing the end beam 2 from slipping off the end of the arc-shaped track 1. In addition, polyurethane buffers 18 are installed at both ends of the end beam 2. In this way, when the end beam 2 accidentally collides with the stop plates 17, the polyurethane buffers 18 can play a buffering role to reduce the degree of damage to the end beam 2.
