Description

Technical Field

[0001] The invention relates to the technical field of box-adjusting doors, and in particular to a machine remote automatic control box-adjusting door. Background Art

[0002] Containers at docks, ports and other places need to be loaded onto trucks and then transported outward. When the containers are loaded onto trucks, due to operational errors, the container doors are placed on the front side of the truck, which is inconvenient for loading and unloading of goods in the container. Therefore, the container doors need to be turned.

[0003] There are two types of existing container turning equipment: reach stackers and gantry cranes. When the reach stacker turns the container, it is necessary to lift the container on the truck, lift the container to a safe position, drive the truck out and turn the front of the truck, and then load the container onto the truck again; when the gantry crane lifts the container, the traditional gantry crane lacks a rotation system and cannot turn the container 180 degrees, and the driver is also required to turn the front of the truck; the above two types of containers need to occupy a large site space when turning the door, resulting in a waste of resources. For the fixed gantry crane dedicated to the door adjustment, when the truck carries the container under the fixed gantry crane, due to the lack of truck position restrictions, the container cannot be accurately placed under the hoist. Since the fixed gantry crane lacks a transverse movement mechanism, the truck driver is required to make a second adjustment to the position of the truck, which reduces the efficiency of container turning. Therefore, how to design a door adjustment device that is convenient for turning the container door has become a technical problem that needs to be solved urgently by technicians in this field. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a machine that can remotely and automatically control the container door adjustment, reduce the site space for container adjustment, improve the adjustment efficiency of the container, and avoid shaking of the equipment when the container is turned.

[0005] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] A machine remotely controlled automatic container door adjustment comprises a frame, a rotating system, a winding system, and a rotary lock system, wherein the rotary lock system is used for grabbing containers, and the winding system is used for raising or lowering the rotary lock system, and a transverse movement system is installed on the frame, and the transverse movement system comprises a transverse movement part sliding on the frame and a first driving part driving the transverse movement part to move transversely, and the transverse movement part comprises a transverse movement plate and a wheel group installed on the lower end surface of the transverse movement plate, and a wheel locking system is installed on the wheel group, and the rotating system comprises a rotating disk installed on the transverse movement plate and a second driving part driving the rotating disk to rotate, the rotary lock system is located below the rotating disk, and the winding system is installed on the lower end surface of the rotating disk, and a central control unit is installed on the frame, and the first driving part, the rotary lock system and the wheel locking system are all communicatively connected with the central control unit, and when the rotary lock system grabs the container, the wheel locking system locks the wheel group, and when the rotary lock system does not grab the container, the wheel locking system releases the lock of the wheel group.

[0007] In the present invention, the truck is driven under the frame so that the direction of the truck head is consistent with the moving direction of the transverse movement system, the reeling system is used to lower the rotary lock system, and then the rotary lock system is used to grab the container, and then the reeling system is used to lift the rotary lock system and the container, and the rotary system is driven to rotate 180 degrees, and then the container door is turned, and the container is placed on the truck again by using the reeling system and the rotary lock system, and the container door adjustment is completed. The driver does not need to adjust the direction of the truck head, which reduces the space occupied by the door adjustment and saves space.

[0008] When the container on the truck deviates from the position of the rotary lock system, the transverse moving part in the transverse moving system drives the transverse moving plate to slide on the frame, and then adjusts the rotary lock system to the top of the container. The driver does not need to move the truck to adjust the position of the container, which improves the efficiency of container transfer.

[0009] When the twistlock system lifts the container, the hook is first inserted into the container and twisted to lock it. Before the container is lifted, the central control unit determines the status of the twistlock system and controls the wheel locking system to lock or open the wheel group to prevent the transverse plate from sliding at the moment the container is lifted, reduce the impact on the transverse system, and improve the stability of the equipment.

The transverse portion 21 includes a transverse plate 211 and a wheel group 212 installed on the lower end surface of the transverse plate 211. The wheel group 212 is equipped with a wheel locking system, as shown in FIG. Figure 5 As shown, the rotating system 3 includes a rotating disk 32 installed on the transverse plate 211 and a second driving part driving the rotating disk 32 to rotate, the rotary lock system 5 is located below the rotating disk 32, and the winding system 4 is installed on the lower end surface of the rotating disk 32. A central control unit 10 is installed on the frame 1, and the first driving part 22, the rotary lock system 5 and the wheel locking system are all communicatively connected with the central control unit 10. When the rotary lock system 5 grabs a container, the wheel locking system locks the wheel group 212. When the rotary lock system 5 does not grab a container, the wheel locking system unlocks the wheel group 212.

[0036] Specific: Combined Figure 1 and Figure 2 As shown, the rotating system 3 includes a channel 31 opened on the transverse plate 211, a rotating groove 33 is opened on the upper end surface of the transverse plate 211, a rotating wheel 34 is installed on the lower end surface of the rotating disk 32, and the rotating wheel 34 rolls in the rotating groove 33.

The gearbox 36 and the motor 37 are fixedly installed on the positioning frame 35. The output end of the motor 37 is fixedly connected to the input end of the gearbox 36, and the output end of the gearbox 36 is fixedly connected to the rotating disk 32. By driving the motor 37, the rotating disk 32 can be driven to rotate;

[0038] Combination Figure 3 As shown, the rotary lock system 5 includes a rotary lock frame 51 fixedly mounted on the lifting frame 45, and a rotary lock mechanism 52 is installed on the rotary lock frame 51. The rotary lock mechanism 52 includes a rotary lock hook 521 for rotary locking the container and a warning light 522 for determining the rotary lock state of the container. The warning light 522 is electrically connected to the central control unit 10. When the warning light 522 is on, it indicates that the container is grabbed. At this time, the central control unit 10 receives the on signal of the warning light 522 and controls the wheel locking system to lock the wheel group 212. When the warning light 522 is off, the rotary lock hook 521 does not grab the container. The central control unit 10 receives the warning light 522 signal and controls the wheel locking system to release the lock on the wheel group 212.

[0039] like Figure 1 As shown, in this embodiment, the first driving part 22 includes a hydraulic cylinder 221 fixedly mounted on the frame 1 , and a hydraulic rod 222 of the hydraulic cylinder 221 is fixedly connected to the transverse plate 211 .

[0040] When the driver drives the truck to the bottom of the frame 1 along the extension direction of the hydraulic cylinder 211, the hydraulic rod 222 is extended and retracted according to the position of the truck, and then the position of the transverse plate 211 is adjusted to position the rotary lock hook 521 directly above the container, thereby solving the problem in the prior art that the truck driver needs to adjust the position of the truck, thereby adjusting the position of the container and improving the efficiency of container grabbing.

[0041] In order to realize the installation of the wheel set 212, in this embodiment, Figure 5 As shown, the wheel group 212 includes a roller bracket 2121, a roller shaft 2122 and a roller 2123. The roller bracket 2121 is fixedly mounted on the lower end surface of the transverse plate 211, the roller shaft 2122 is rotatably mounted on the roller bracket 2121, and the roller 2123 is fixedly mounted on the roller shaft 2122.

[0042] The wheel set 212 is installed on the lower end surface of the transverse plate 211 to facilitate the relative movement of the transverse plate 211 and the frame 1, thereby reducing the resistance encountered by the transverse plate 211 during the movement.

[0043] In order to achieve the braking of the roller shaft 2122, in this embodiment, as Figure 5 As shown, the wheel locking system includes a brake cylinder 7 and a friction plate 72. The brake cylinder 7 is fixed on a roller bracket 2121. The cylinder rod of the brake cylinder 7 extends into the roller bracket 2121 and is fixed with a brake disc 71. The friction plate 72 is installed on the roller shaft 2122. The brake disc 71 contacts the friction plate 72 to limit the rotation of the roller shaft 2122. The central control unit 10 is electrically connected to the brake cylinder 7.

[0044] Through the above arrangement, when the warning light 522 is on, the central control unit 10 controls the brake cylinder 7 to work, thereby driving the cylinder rod of the brake cylinder 7 to be retracted into the cylinder, thereby driving the brake disc 71 to abut against the friction plate 72, and utilizing the friction force between the brake disc 71 and the friction plate 72 to limit the rotation of the roller shaft 2122, thereby achieving the braking of the roller shaft 2122.

[0045] In order to prevent the wheel set 212 from deviating during movement, in this embodiment, Figure 4 As shown, a transverse groove 213 is provided on the frame 1, and the wheel set 212 moves in the transverse groove 213, thereby effectively preventing the wheel set 212 from deflecting during the movement.

[0046] In order to achieve the locking of the wheel set 212, in this embodiment, as Figure 4 As shown, a locking groove 6 is provided on the lower wall of the transverse groove 213, and a ratchet is provided in the locking groove 6. Figure 5 As shown, the roller shaft 2122 is provided with a locking plate 9, the wheel locking system also includes a transmission assembly, the transmission assembly includes a spline sleeve 81 and a circumferential transmission part, the roller shaft 2122 is connected to the spline sleeve 81 via a spline, the locking plate 9 is connected to the spline sleeve 81 via a bearing, the friction plate 72 is fixedly arranged on the spline sleeve 81, the spline sleeve 81 moves under the power of the brake cylinder 7 and pushes the locking plate 9 to move axially, and the circumferential transmission part includes a top pin 82, guide slider 83, the guide slider 83 is fixed on the roller bracket 2121 and distributed circumferentially along the roller shaft 2122, the ejector pin 82 is fixed on the locking plate 9, the locking plate 9 drives the ejector pin 82 to move axially along the roller shaft 2122, so that the ejector pin 82 contacts and applies force to the guide slider 83 to cause the locking plate 9 to rotate circumferentially at an angle relative to the roller bracket 2121, and the locking plate 9 rotates from the initial position to the final position under the action of the transmission component. When in the final position, Figure 7 and Fig.12 As shown, the locking plate 9 rotates into the locking groove 6 and abuts against the ratchet to limit the movement of the wheel set 212.

[0047] Through the above-mentioned arrangement, the brake cylinder 7 drives the brake disc 71 to abut against the friction plate 72 and pushes the spline sleeve 81 to move along the axial direction of the roller shaft 2122, thereby driving the locking plate 9 to move axially along the roller shaft 2122. When the push pin 82 on the locking plate 9 abuts against the guide slider 83 and continues to move axially, the push pin 82 applies force to the guide slider 83, thereby driving the locking plate 9 to rotate, and then rotating the edge of the locking plate 9 into the locking groove 6 and abutting against the ratchet, thereby limiting the movement of the wheel group 212.

[0048] In order to strengthen the braking of the wheel set 212, in this embodiment, as Figure 6 As shown, two locking grooves 6 are provided and distributed on both sides of the roller 2123, the ratchet teeth inside the locking grooves 6 on both sides are in opposite directions, wheel locking systems are provided on both sides of the roller 2123, and the locking plates 9 on both sides of the roller 2123 turn in opposite directions.

[0049] Through the above arrangement, when the locking plates 9 on both sides of the roller 2123 rotate into the locking groove 6, the rotation directions of the locking plates 9 on both sides of the roller 2123 are opposite, and the movement of the wheel group 212 in two directions is restricted at the same time, thereby strengthening the locking of the wheel group 212.

[0050] In order to realize the reset of the locking plate 9, in this embodiment, as Figure 8 As shown, the circumferential transmission part further includes a torsion spring 85 , one end of which is fixed on the locking plate 9 , and the other end of which is fixed on the roller bracket 2121 .

[0051] Through the above arrangement, when the wheel assembly 212 is locked, the torsion spring 85 is in a compressed state and rotates an angle along with the locking plate 9. When the brake cylinder 7 stops locking the roller shaft 2122, the torsion spring 85 drives the locking plate 9 to rotate and disengage from the locking groove 6. At the same time, the compression force on the torsion spring 85 is released, thereby pushing the spline sleeve 81 to move along the axial direction of the roller shaft 2122, thereby realizing the resetting of the locking plate 9.

[0052] In order to realize the turnover of the locking plate 9, in this embodiment, as Figure 6 and Fig.12 As shown, the guide sliding block 83 includes a guide sliding surface 831 , and the ejector pin 82 abuts against the guide sliding surface 831 to drive the locking plate 9 to rotate, wherein the guide sliding surface 831 is an arc surface.

[0053] The arc surface structure of the guide sliding surface 831 is utilized to accelerate the sliding of the ejector pin 82 and the guide sliding block 83, thereby facilitating driving the locking plate 9 to rotate.

[0054] In order to achieve the limitation of the locking plate 9, in this embodiment, as Figure 6 and Fig.12As shown, a locking hole 84 is opened on the roller bracket 2121, and the guide slider 83 is fixed in the locking hole 84. The guide slider 83 also includes a limiting surface 832. The ejector pin 82 contacts the limiting surface 832 to limit the continuous rotation of the locking plate 9.

[0055] Through the above arrangement, when the wheel set 212 is in the locked state, the locking plate 9 moves to the extreme state and approaches the guide slider 83. At this time, the push pin 82 extends into the locking hole 84 and abuts against the limiting surface 832 of the guide slider 83, thereby limiting the locking plate 9 from continuing to rotate.

[0056] The above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the scope of protection required by the present invention.
