Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of port gantry operation monitoring, in particular to a mobile monitoring system for port gantry operation. BACKGROUND

[0002] The port gantry is a hoisting equipment used for loading and unloading containers in the port, which is usually installed on the wharf and can move containers vertically and horizontally. It travels on the wharf through a rail system, is equipped with a hoisting arm, a hook, a lifting appliance and other equipment, and is responsible for lifting containers from a ship or loading them onto a ship. During the operation of the port gantry, the lifting and moving of containers and the changes in the surrounding environment need to be monitored in real time. Real-time monitoring can ensure efficient, safe and accurate operation, especially when the gantry is lifting a heavy object. The operator needs to know the positioning of the container, the status of the hook and the changes in the surrounding environment in real time to avoid accidents or operational errors. Therefore, monitoring equipment is a necessary tool to improve operational efficiency and reduce safety hazards. The common installation position of the monitoring equipment of the port gantry is the main beam of the gantry, which can better cover the front and rear and the upper and lower operation areas of the gantry, and can observe the lifting and handling process of the container and the movement of the gantry to enable the operator to understand the progress of the operation in real time.

[0003] However, the existing monitoring equipment can usually only be installed at fixed points. Although they can be rotated to adjust the field of view in the circumferential direction, their monitoring range is limited because their position cannot be adjusted. Their field of view is often limited. In order to observe the field of view on both sides of the main beam of the gantry, multiple cameras need to be installed on both sides of the main beam. However, since each device can only cover a specific area and cannot be adjusted in position according to the specific operation requirements, the monitoring system may not be able to capture key operational details or potential dangerous areas in time, increasing the risk during the operation.

[0004] In addition, strong winds can cause the monitoring equipment installed on the gantry to sway, especially when the equipment is installed at a high position and has a large external exposure area. The sway can cause the camera image to be unstable or blurred, affecting the operator's judgment of the operation situation, and even missing potential safety hazards due to unclear images. SUMMARY

[0035] When long distance monitoring range adjustment is needed, the electric sliding support block 2 is controlled to move in the transverse direction along the bearing rail seat 1, and then the electric sliding support block 2 indirectly drives the monitoring head 48 to move in the transverse direction through the mounting cylinder 3, the sliding column seat 41, the mounting disc 42 and the mounting cover box 46, so that the shooting transverse shooting range of the monitoring head 48 can be adjusted in a long distance, and then the electric telescopic rod 43 is controlled to extend and push the sliding column seat 41 to move downward, and then the sliding column seat 41 drives the mounting disc 42 and the mounting cover box 46 to move downward as a whole, and then the mounting cover box 46 drives the monitoring head 48 to move downward, so that the longitudinal monitoring range of the monitoring head 48 can be adjusted, and then the monitoring head 48 is first moved downward and then moved to the other side of the gantry beam in the transverse direction by using the electric telescopic support 471, so that the different working areas of the gantry crane can be monitored, the monitoring range is greatly expanded, and the number of monitoring devices is also reduced.

[0037] When the electric telescopic support 471 extends and drives the monitoring head 48 to move out of the mounting cover box 46, the monitoring head 48 also drives the pulling rope 495 to move, and then the pulling rope 495 pulls the sliding block 494 to slide in the sliding groove 493, the top spring is compressed by the sliding block 494, the pulling rope 495 is in a taut state, and the upward pulling force of the monitoring head 48 is exerted by the pulling rope 495 through the reaction force of the compressed top spring, so that the stability of the monitoring head 48 after extension is ensured, and the instability caused by the single cantilever is avoided.

The upper end surface of the mounting block 51 is fixedly connected with a lug seat 54, the lug seat 54 is hingedly connected with a cantilever rod 55 through an ear block, the cantilever rod 55 and the mounting block 51 are jointly fixedly connected with a tension spring 56, a winding drum 57 is rotatably arranged on the support plate group 53, a rotating shaft is rotatably connected to the support plate group 53, the rotating shaft and the support plate group 53 are jointly fixedly connected with a torsion spring, the winding drum 57 is fixedly connected to the outside of the rotating shaft, a drawstring 510 is woundly arranged on the outside of the winding drum 57, one end of the drawstring 510 away from the winding drum 57 is fixedly connected to the cantilever rod 55, the cantilever rod 55, the sliding column base 41 and the drawstring 510 are combined to form a triangle to prevent the sliding column base 41 from swinging, the sliding column base 41 and the mounting cylinder 3 are jointly provided with a locking assembly 58 for locking and limiting the cantilever rod 55 in a horizontal state of rotation, the mounting disc 42 and the winding drum 57 are jointly provided with a lock rotation assembly 59 for locking the winding drum 57, and the elastic coefficient of the torsion spring is greater than that of the tension spring 56.

[0039] Please refer to Figure 6 and Figure 7 The locking assembly 58 comprises vertical grooves, a disc 581, mounting grooves 582, locking insertion grooves 583, sliding blocks 584 and locking insertion columns 585. The inner cavity of the mounting cylinder 3 is axially symmetrically provided with vertical grooves, the two vertical grooves are jointly and slidably connected with the disc 581 through sliding blocks, the outer wall of the disc 581 is circumferentially equidistantly provided with a plurality of mounting grooves 582 corresponding to the cantilever rod 55 and having a T-shaped longitudinal section, the cantilever rod 55 and the lug seat 54 are respectively provided with locking insertion grooves 583, the sliding blocks 584 are slidably connected in the mounting grooves 582, the sliding blocks 584 and the mounting grooves 582 are jointly fixedly connected with return springs, the lower end surface of the sliding block 584 is fixedly connected with the locking insertion column 585 matched with the locking insertion groove 583, and the upper end surface of the sliding column base 41 is symmetrically fixedly connected with two top rods 586 for driving the disc 581 to move longitudinally.

[0040] Please refer to Figure 4 and Figure 5The lock rotating assembly 59 comprises a ring-shaped installation groove 591 formed in the upper end face of the installation disc 42, two spring telescopic columns 592 symmetrically and fixedly connected to the groove bottom of the installation groove 591, a ring-shaped seat 593 commonly fixedly connected to the upper ends of the spring telescopic columns 592, a plurality of clamping grooves 594 equidistantly and fixedly connected to the outer wall of the winding drum 57, a plurality of clamping tooth groups 595 equidistantly and fixedly connected to the upper end face of the ring-shaped seat 593 and clamped with the clamping grooves 594, and a jacking part 6 provided between the installation disc 42 and the electric telescopic support 471 and used for driving the upward movement of the ring-shaped seat 593. The jacking part 6 comprises two slide rods 61 symmetrically and slidingly connected to the installation disc 42 and located in the installation groove 591, the slide rods 61 being fixedly connected to the lower end face of the ring-shaped seat 593, a linkage ring 62 commonly fixedly connected to the lower ends of the two slide rods 61, a strip-shaped through groove 63 symmetrically formed in the upper part of the installation cover box 46, and a linkage column 64 slidingly connected in the strip-shaped through groove 63, the linkage column 64 being fixedly connected to the wedge-shaped plates 65 matched with the linkage ring 62 at the upper ends of the linkage column 64 and hingedly connected to the electric telescopic support 471 at the lower ends of the linkage column 64.

[0041] When the monitoring head 48 is in the initial state of non-working, the sliding column seat 41 is retracted in the installation cylinder 3, the electric telescopic rod 43 is in the shortest length, and the cantilever rod 55 is in the vertical state of being retracted in the installation cylinder 3. When the monitoring head 48 needs to move downward, the electric telescopic rod 43 is elongated to drive the sliding column seat 41 to move downward, the sliding column seat 41 is then driven by the branch plate group 53 and the rotating shaft to move downward, the winding drum 57 is then driven by the inhaul cable 510 to rotate the cantilever rod 55, until the cantilever rod 55 changes from the vertical state to the horizontal state, the cantilever rod 55 is rotated to extend into the strip-shaped through groove 52, and finally, the cantilever rod 55 is abutted against the lower groove wall of the strip-shaped through groove 52. During the rotation of the cantilever rod 55 to the horizontal state, the sliding column seat 41 drives the upward movement of the top rod 586, the top rod 586 then drives the disc 581 to move downward along the vertical groove, the sliding block 584 abutted against the cantilever rod 55 is gradually moved outward under the driving of the return spring, the sliding block 584 then drives the synchronous movement of the locking plug 585, the locking slot 583 on the cantilever rod 55 is aligned with the locking slot 583 on the lug seat 54 when the cantilever rod 55 changes to the horizontal state, the locking plug 585 driven by the disc 581 to move downward is then inserted into the locking slot 583, and thus the cantilever rod 55 changed to the horizontal state can be locked.

[0042] The upper end of the cable 510 is fixed, and the sliding column base 41 continues to move downward and drives the rotating and winding drum 57 to rotate synchronously through the support plate group 53. The rotation of the winding drum 57 releases the cable 510, and the released cable 510 is in a taut state under the action of the torsion spring. When the sliding column base 41 moves to the required position and stops, the electric telescopic support 471 needs to be extended to drive the monitoring head 48 to move out of the installation cover box 46. The electric telescopic support 471 is extended and simultaneously drives the two linkage columns 64 connected therewith to move away from each other. The linkage columns 64 then drive the wedge-shaped plates 65 connected therewith to move synchronously. When the two wedge-shaped plates 65 move away from each other, the inclined surfaces thereof will press the lower part of the extrusion linkage ring 62, and then press the linkage ring 62 to move upward. The linkage ring 62 then drives the ring-shaped seat 593 to move upward through the slide rod 61. The ring-shaped seat 593 then drives the toothed gear set 595 to move upward, until the toothed gear set 595 is clamped into the clamping groove 594 on the outer wall of the winding drum 57. At this time, the upper end surface of the wedge-shaped plate 65 abuts against the lower part of the linkage ring 62, so as to lock and position the winding drum 57. The cable 510, the cantilever rod 55 and the sliding column base 41 form a triangular structure, the sliding column base 41 is pulled from multiple directions through the circumferentially distributed cable 510, and the stability of the sliding column base 41 is greatly enhanced. The monitoring head 48 is not swung by strong wind due to single installation point.

[0043] When the monitoring head 48 stops monitoring, the electric telescopic support 471 is controlled to retract and pull the monitoring head 48 into the installation cover box 46. The electric telescopic support 471 is retracted and simultaneously drives the two linkage columns 64 to move close to each other. The linkage columns 64 then drive the wedge-shaped plates 65 to move close to each other, until the wedge-shaped plates 65 move to the initial position separated from the linkage ring 62. After the linkage ring 62 loses the driving of the wedge-shaped plates 65, the spring telescopic column 592 is reset and retracted to drive the ring-shaped seat 593 to move downward. The ring-shaped seat 593 then drives the toothed gear set 595 to separate from the clamping groove 594. Then, the electric telescopic rod 43 is controlled to retract and drive the sliding column base 41 to move upward. During the upward movement of the sliding column base 41, the torsion spring in the twisted state drives the rotating shaft to reverse, and the rotating shaft then drives the winding drum 57 to rotate and wind up the cable 510.

[0044] When the sliding column 41 moves a distance, the top rod 586 is in contact with the lower part of the disc 581, and then the disc 581 is moved upward synchronously, and then the disc 581 drives the locking plug 585 to move upward through the sliding block 584, until the locking plug 585 is moved out of the locking slot 583, and then the tensile spring 56 in the stretched state is reset to shrink and pull the overhanging rod 55 to rotate around the lug seat 54 towards the axis of the mounting cylinder 3, and the overhanging rod 55 will also be in contact with the sliding block 584 during the process of gradually rotating and shrinking into the mounting cylinder 3, and then the sliding block 584 is gradually retracted into the mounting slot 582, and the sliding block 584 drives the locking plug 585 to move synchronously, until the overhanging rod 55 is completely rotated and retracted into the mounting cylinder 3, and the initial vertical state is restored, and the sliding block 584 is also driven to retract the locking plug 585 into the mounting slot 582.

[0045] In operation, the mounting hole on the mounting lug plate 7 is aligned with the reserved hole on the main beam of the door machine for mounting the monitoring device, and then the bolt is screwed into the mounting hole and the reserved hole to mount the bearing rail seat 1 on the main beam of the door machine, and then the longitudinal movement of the sliding column in the multi-zone self-adjusting monitoring mechanism 4 and the transverse extension of the electric telescopic support 471 are controlled to drive the monitoring head 48 to move longitudinally and transversely for a short distance, and then the electric sliding support block 2 is controlled to drive the multi-zone self-adjusting monitoring mechanism 4 to move transversely for a long distance, so that the monitoring head 48 can be moved from different directions to expand the monitoring range of the monitoring head 48, and the longitudinal and transverse adjustment of the multi-zone self-adjusting monitoring mechanism 4 simultaneously triggers the stable swing suppression mechanism 5 to operate, and the stable swing mechanism pulls the multi-zone self-adjusting monitoring mechanism 4 from multiple directions to enhance the stability of the pulling of the multi-zone self-adjusting monitoring mechanism 4, and avoid the situation that the pulling of the multi-zone self-adjusting monitoring mechanism 4 swings due to strong wind.
