Description

Technical Field

[0001] The present invention relates to a crane handling system, belonging to the technical field of cranes. Background Art

[0002] Traditional cranes run on preset tracks. Cranes operate independently between tracks without movement intersections with each other, serving parallel areas, which makes it difficult to carry materials between adjacent areas. Currently, there are new types of cranes with telescopic functions that can extend into the service area of adjacent cranes to complete the work of loading and unloading materials. However, due to the intersection of their operations and the fact that the operating height of general cranes is 10m or even higher, operators often operate on the ground with limited visibility, so their safety protection is particularly important. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a crane handling system. By setting sensor components on fixed cranes and telescopic cranes, and collecting the relative position relationships, the operation conditions of the cranes corresponding to different sensor components are controlled. It is a mechanical safety protection device with high reliability, simple and compact structure, low cost and easy to promote.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is:

Description of the Drawings

[0016] Figure 1 is a schematic structural diagram of a crane handling system of the present invention;

[0017] Figure 2 is Figure 1 an enlarged schematic diagram of A in Detailed Embodiments

[0018] The present invention will be further described below in conjunction with the drawings of the specification.

[0019] As shown in Figure 1 and Figure 2 A crane handling system includes a telescopic crane and a fixed crane arranged in parallel. The main beam 10 of the telescopic crane and the main beam 20 of the fixed crane are respectively installed on corresponding tracks 60. A telescopic beam 30 capable of horizontally moving relative to the main beam 10 of the telescopic crane to the active area where the main beam 20 of the fixed crane is located is provided on the main beam 10 of the telescopic crane. Crane main machines 50 are installed on both the main beam 20 of the fixed crane and the telescopic beam 30. A first sensor assembly 21 and a first trigger plate 22 electrically connected to the fixed crane are provided on the main beam 20 of the fixed crane. A second trigger plate 13 corresponding to the position of the first sensor assembly 21 and a second sensor assembly 18 corresponding to the position of the first trigger plate 22 and electrically connected to the telescopic crane are provided on the main beam 10 of the telescopic crane. The second trigger plate 13 can rotate up and down as the telescopic beam 30 moves. A displacement sensor electrically connected to the telescopic crane for detecting the position of the telescopic beam 30 relative to the main beam 10 of the telescopic crane is provided on the telescopic beam 30.

[0020] When the telescopic beam 30 does not extend out of the main beam 10 of the telescopic crane and enter the active area where the fixed crane is located, the second trigger plate 13 is pulled up, and the displacement sensor will not trigger the main beam 10 of the telescopic crane to stop moving. The main beam 10 of the telescopic crane and the main beam 20 of the fixed crane can move arbitrarily along their respective tracks.

[0021] When the telescopic beam 30 extends out of the main beam 10 of the telescopic crane and enters the active area where the fixed crane is located, first, the displacement sensor sends a signal to the telescopic crane. When the main beam 10 of the telescopic crane and the main beam 20 of the fixed crane move relative to each other and the second sensor assembly 18 contacts and is triggered by the first trigger plate 22, the second sensor assembly 18 sends a signal to the telescopic crane to trigger it to stop moving, avoiding a collision between the telescopic beam 30 and the main beam 20 of the fixed crane; after the telescopic beam 30 extends out, the second trigger plate 13 reaches the horizontal position. When the main beam 10 of the telescopic crane and the main beam 20 of the fixed crane move relative to each other and the first sensor assembly 21 is triggered by the second trigger plate 13, the first sensor assembly 21 sends a signal to the fixed crane to trigger it to stop moving, avoiding a collision between the telescopic beam 30 and the main beam 20 of the fixed crane.

[0022] Mechanical structures are used to achieve safety protection, and whether each crane stops moving is judged by the sensor assemblies on their respective cranes. There is no signal transmission between the two cranes, further saving costs.

[0023] Among them, two sets of trolleys 40 for driving the telescopic beam 30 to move horizontally relative to it are provided on the telescopic crane main beam 10, and a displacement sensor for detecting whether the telescopic beam 30 extends towards the fixed crane direction is provided on the trolley 40. By detecting the distance that the trolley 40 moves relative to the telescopic crane main beam 10 through the displacement sensor, the telescopic state of the telescopic beam 30 can be determined.

[0024] In this embodiment, a pulley 14 and a lever 11 are further provided on the telescopic crane main beam 10. A steel wire rope 15 passing through the pulley 14 is provided between the lever 11 and the second trigger plate 13, and a driving plate 31 for pushing the lever 11 to rotate is provided on the telescopic beam 30.

[0025] When the telescopic beam 30 does not extend into the fixed crane main beam 20, the driving plate 31 pushes the lever 11 to rotate, thereby driving the trigger plate 13 to rotate upward. During the process of the sensor assembly 21 moving with the fixed crane main beam 20, it will not be triggered. When the telescopic beam 30 is about to extend into the fixed crane main beam 20, the limit of the driving plate 31 on the lever 11 is cancelled, and the trigger plate 13 moves downward to the horizontal position under the action of gravity, as Figure 1 shown. At this time, when the sensor assembly 21 moves to the trigger plate 13, it will be triggered, thereby sending a stop signal to the fixed crane main beam 20 until the telescopic beam retracts, the lever 11 is rotated, and the trigger signal of the sensor assembly 21 disappears, then the control of the fixed crane main beam 20 can continue to work, avoiding collisions in the overlapping area, and it is realized by a mechanical structure with low cost.

[0026] Among them, a stop rod 16 for restricting the rotation angle of the lever 11 is further provided on the telescopic crane main beam 10. When the lever 11 rotates to the stop rod 16, the trigger plate 13 is exactly at the same height as the sensor assembly 21, which can effectively trigger the sensor assembly 21.

[0027] The lever 11 is bent, one end is connected to the steel wire rope 15, and the other end is a roller 17 that can contact the driving component 31, and one end of the sensor trigger device driving component 31 close to the roller 17 is inclined downward. Ensure that there is a certain buffering process during the contact between the two to avoid direct hard contact and damage to the product.

[0028] The trigger plate 13 is fixedly connected to the trigger plate fixing seat 12, and the trigger plate fixing seat 12 is rotatably connected to the telescopic crane main beam 10.

[0029] The number of the first sensor assemblies 21 is two, which are respectively arranged at the front and rear ends of the main beam 20 of the stationary crane, so as to ensure that when the telescopic beam 30 enters the main beam 20 of the stationary crane, the sensor assemblies 21 can be triggered no matter the main beam 20 of the stationary crane moves in the front and rear directions.

[0030] The number of the second sensor assemblies 18 is two, which are respectively arranged at the front and rear ends of the main beam 10 of the telescopic crane, and have the same function as the above two first sensor assemblies 21.

[0031] Both ends of the trigger plate 13 are provided with inclined buffer guiding structures, so as to ensure that there is a certain buffer process when the sensor assembly 21 contacts the trigger plate 13, and avoid direct hard contact, which may cause damage to the product.

[0032] In summary, a crane handling system provided by the present invention is a mechanical safety protection device with high reliability, simple and compact structure, and low cost and easy to promote. By setting sensor assemblies on the stationary crane and the telescopic crane and collecting the relative position relationship, the operation conditions of the cranes corresponding to different sensor assemblies are controlled.
