Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to an unattended intelligent crane. Background Technology

[0002] An unattended intelligent crane is a highly automated lifting device that can complete tasks such as grabbing, moving, and placing materials without direct human operation. This type of crane achieves automation and intelligence in operation by integrating wireless network technology, PLC control technology, and HMI technology.

[0003] A search revealed a Chinese utility model patent application (CN219771580U, published on September 29, 2023) for an intelligent unattended crane. The application describes a system where "an integrated control box controls electrical components installed inside the crane, and a laser scanning imager scans and identifies materials below the crane, facilitating automatic material gripping by a clamping assembly mounted below the control panel. The integrated control box controls the hoist motor, causing the hoisting rope on its outer side to rotate and release. As the rope releases, the control panel gradually lowers. Rotation of the electric telescopic rod's output unfolds the gripper hinged to the outer side of the fixed base plate. A laser rangefinder measures the distance between the clamping assembly and the material and transmits this information to the integrated control box. Upon reaching the gripping height, retraction of the electric telescopic rod's output allows the gripper to pick up the material. The laser scanning imager then identifies the area and transfers the material to another location. This crane can operate unattended, reducing operator workload and improving efficiency."

[0004] However, in the above-mentioned technical solutions, the intelligent operation of the crane relies entirely on the control components inside the integrated control box, which places an excessive workload on these components. Since intelligent cranes need to operate for extended periods to free up labor and improve efficiency, the control components inside the control box generate a large amount of heat during prolonged operation. This accelerates the aging of the control components, reducing their lifespan and leading to frequent malfunctions. Furthermore, the control box in the above-mentioned technical solutions does not facilitate easy maintenance by operators, increasing the difficulty and risk of maintenance work.

[0005] Therefore, an unmanned intelligent crane is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an unattended intelligent crane to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: An unattended intelligent crane includes two bridge frames. The bottom of each bridge frame is welded with a movable wheel. A first drive motor is bolted to one side of each movable wheel. A support groove is opened on the top of each of the two bridge frames. A lifting trolley is movably installed inside the two support grooves. An unattended control integrated box assembly is fixed to the top of the lifting trolley. A lifting rope is installed at the bottom of the lifting trolley. A mounting plate is connected to the bottom of the lifting rope. A rotating plate is rotatably installed on the bottom of the mounting plate. A connecting rod is welded to the bottom of the rotating plate. A grab bucket is rotatably installed at each end of the connecting rod. A hydraulic telescopic rod is rotatably installed on each side of the bottom of the rotating plate. The output ends of the two hydraulic telescopic rods are rotatably connected to the top of the grab buckets. A second drive motor is bolted to the top of the mounting plate.

[0007] Preferably, the output end of the second drive motor passes through the interior of the mounting plate, and the output end of the second drive motor is fixedly connected to the top of the rotating plate.

[0008] Preferably, the bottom of the mounting plate is provided with an annular limiting groove, and a limiting slide rod is welded to each of the two sides of the top of the rotating plate. The two limiting slide rods are slidably installed inside the annular limiting groove. A lifting lug is welded to each of the two sides of the top of the mounting plate, and the inside of the two lifting lugs is respectively limited and connected to one end of the lifting rope.

[0009] Preferably, the unmanned control integrated box assembly includes a base, and an editable control element body is installed on the top of the base. A side plate is fixed to one side of the top of the base, and a control panel is installed on one side of the side plate. The control panel is electrically connected to the editable control element body. A slot is provided on the top of the base, and a protective shell is installed on the top of the base.

[0010] Preferably, the bottom of the protective shell is welded with an insert plate, and the insert plate is installed in conjunction with the slot. A limiting groove is provided on one side of the side plate, and a limiting slide plate is welded on one side of the protective shell.

[0012] Compared with the prior art, this utility model provides an unattended intelligent crane, which has the following beneficial effects:

[0013] The unmanned control integrated box assembly enables intelligent control of the drive units installed throughout the crane. During maintenance, the entire protective shell can be removed from one side of the side panel using handles welded to the top two sides of the shell. This exposes the control components inside the assembly to the outside, facilitating maintenance and reducing the risk of accidents. Simultaneously, the rotation of the electric exhaust fan dissipates the heat generated inside the assembly, lowering the internal working temperature and preventing the control components from operating in high-temperature environments for extended periods. This slows down the aging of the control components, extends their lifespan, and reduces the failure rate. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: There are two cable trays 1. The bottom of the two cable trays 1 is welded with movable wheels 2. A first drive motor 3 is bolted to one side of the movable wheels 2. A support groove 13 is opened on the top of the two cable trays 1 respectively. A lifting trolley 4 is movably installed inside the two support grooves 13. An unmanned control integrated box assembly 5 is fixed on the top of the lifting trolley 4. A hoisting rope 7 is installed on the bottom of the lifting trolley 4. An installation plate 8 is connected to the bottom of the hoisting rope 7. A rotating plate 9 is rotatably installed on the bottom of the installation plate 8. A connecting rod 10 is welded to the bottom of the rotating plate 9. A grab bucket 11 is rotatably installed at both ends of the connecting rod 10. A hydraulic telescopic rod 12 is rotatably installed on both sides of the bottom of the rotating plate 9. The output ends of the two hydraulic telescopic rods 12 are rotatably connected to the top of the grab bucket 11 respectively. A second drive motor 6 is bolted to the top of the installation plate 8.

[0022] The unmanned control integrated box assembly 5 includes a base 504, and an editable control element body 506 is mounted on the top of the base 504. A side plate 501 is fixed to one side of the top of the base 504, and a control panel 503 is mounted on one side of the side plate 501. The control panel 503 is electrically connected to the editable control element body 506. A slot 505 is provided on the top of the base 504, and a protective shell 507 is mounted on the top of the base 504.

[0023] The bottom of the protective shell 507 is welded with a plug plate 5012, and the plug plate 5012 is installed in conjunction with the slot 505. A limiting groove 502 is provided on one side of the side plate 501, and a limiting slide plate 5011 is welded on one side of the protective shell 507. The limiting slide plate 5011 is installed in conjunction with the limiting groove 502. The top view of the limiting groove 502 and the limiting slide plate 5011 are respectively convex.

[0024] The bottom and one side of the protective housing 507 are open, and filters 5013 are installed on the three sides of the protective housing 507. An exhaust hood 509 is installed on the top of the protective housing 507, and the exhaust hood 509 is connected to the interior of the protective housing 507. An electric exhaust fan 508 is installed inside the exhaust hood 509. A handle 5010 is welded to each of the two sides of the top of the protective housing 507.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, since the top of the hoisting trolley 4 is equipped with an unmanned control integrated box assembly 5, the drive devices installed in the entire crane can be intelligently controlled through the unmanned control integrated box assembly 5. Since the unmanned control integrated box assembly 5 includes a base 504 and a protective shell 507, and the top of the base 504 is equipped with an editable control element body 506, the crane's operating program can be edited and controlled through the editable control element body 506. When inspecting the control components installed inside the unmanned control integrated box assembly 5, the entire protective shell 507 can be removed from one side of the side plate 501 through the handles 5010 welded on both sides of the top of the protective shell 507. When removed, the limit slide plate 5011 will slide out along the inside of the limit slide groove 502, and the insert plate 5012 will slide out from the inside of the slot 505. By removing the protective housing 507, the control components installed inside the unmanned control integrated box assembly 5 are completely exposed to the outside environment, making it easier for maintenance personnel to inspect and repair them, reducing the danger during maintenance. After maintenance is completed, the protective housing 507 is installed on top of the base 504. At the same time, the rotation of the electric exhaust fan 508 can dissipate the heat generated inside the unmanned control integrated box assembly 5 during operation. The filter 5013 allows outside air to enter the interior of the unmanned control integrated box assembly 5, thereby exchanging heat to lower the temperature of the internal working environment of the unmanned control integrated box assembly 5. This prevents the control components inside the unmanned control integrated box assembly 5 from operating in a high-temperature environment for a long time, thus slowing down the aging of the control components, increasing their service life, and reducing the failure rate.

[0026] By controlling the rotation of the output end of the first drive motor 3, the moving wheel 2 can be driven to operate, thereby moving the entire crane along the installation direction of the gantry, while the hoisting trolley 4 can move along the support groove 13 opened on the top of the two bridge frames 1.

[0027] Example 2: The output end of the second drive motor 6 passes through the interior of the mounting plate 8, and the output end of the second drive motor 6 is fixedly connected to the top of the rotating plate 9. An annular limiting groove 801 is provided at the bottom of the mounting plate 8, and a limiting slide rod 901 is welded to each of the two sides of the top of the rotating plate 9. The two limiting slide rods 901 are slidably installed inside the annular limiting groove 801. A lifting lug 802 is welded to each of the two sides of the top of the mounting plate 8, and the interior of the two lifting lugs 802 is limitedly connected to one end of the lifting rope 7.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the length of the hoisting rope 7 can be extended or retracted by the lifting trolley 4, thereby lowering or raising the height of the grab bucket 11 above the ground. The rotation of the output end of the second drive motor 6 can drive the rotating plate 9 to rotate below the mounting plate 8, thereby changing the clamping direction of the two grab buckets 11 on the material. When the rotating plate 9 rotates, the limiting slide rods 901 welded on both sides of the top of the rotating plate 9 will slide along the opening direction of the annular limiting groove 801, thereby ensuring the stability of the rotation of the rotating plate 9. Then, by controlling the extension and retraction of the output end of the hydraulic telescopic rod 12, the two grab buckets 11 can be driven to clamp and transfer the material.

[0029] Working principle: In use, the rotation of the output end of the first drive motor 3 is controlled by the unmanned control integrated box assembly 5 to move the entire crane along the direction of the gantry installed inside the warehouse. The lifting trolley 4 is controlled by the unmanned control integrated box assembly 5 to slide along the opening direction of the support groove 13, thereby adjusting the position of the grab bucket 11. Then, the length of the hoisting rope 7 is extended or retracted by the lifting trolley 4, thereby lowering or raising the height of the grab bucket 11 from the ground. The rotation of the output end of the second drive motor 6 can drive the rotating plate 9 to rotate below the mounting plate 8, thereby changing the clamping direction of the two grab buckets 11 on the material. Finally, the extension and retraction of the output end of the hydraulic telescopic rod 12 is controlled by the unmanned control integrated box assembly 5 to drive the two grab buckets 11 to clamp and transfer the material.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
