Description

Technical Field

[0001] This utility model relates to the field of crane control technology, and in particular to a grab crane control device. Background Technology

[0002] Grab cranes, also known as grab hoists, are lifting machines equipped with grabs. They are widely used in ports, docks, railway freight yards, mines, and other places to load various bulk cargo, logs, minerals, coal, sand and gravel, earthwork, etc. Grab cranes are automatic material handling machines. Their grabbing and unloading actions are operated by the unloader operator, without the need for auxiliary personnel. This avoids heavy labor for workers, saves auxiliary work time, and greatly improves loading and unloading efficiency.

[0003] An investigation revealed that a Chinese utility model patent, CN212115882U, discloses a multi-functional anti-drop controller. This controller includes a main body with a wire connector at its top and a dustproof box on its exterior. The outer wall of the dustproof box is lined with a rubber block, and the inner wall of the rubber block has a locking block. A locking groove is formed on the outside of the locking block, inside the dustproof box. This utility model, by adding a dustproof box and rubber blocks, provides dust protection, ensuring the cleanliness of the controller. The rubber blocks effectively cushion the impact of drops, improving the controller's drop resistance. Furthermore, the addition of a cable management plate, cable management holes, and a sponge layer allows for orderly connection of the cables to the connectors within the wire connector, preventing the cables from becoming tangled inside the dustproof box. The sponge layer also protects the cables within the cable management holes, preventing damage from the inner wall of the holes.

[0004] The aforementioned patents, when used by users, cannot achieve multi-angle rotation adjustment, making it difficult to adapt to the operating habits of different operators and diverse work scenarios. This can easily lead to operator fatigue during long-term work, affecting operational efficiency. Furthermore, they cannot be flexibly adjusted according to the operator's height and viewing angle, resulting in inconvenience in viewing displayed information, further reducing the comfort and convenience of operation. Moreover, their movement structure design is simple, mostly relying solely on bottom rollers for movement, lacking a stable structure to assist movement. During movement, it is difficult to accurately control the direction, resulting in poor stability, especially when moving on uneven work sites. Therefore, there is a particular need for a grab bucket crane control device. Utility Model Content

[0013] Preferably, the supporting base plate is connected to the fixed plate via a first telescopic rod, and the first telescopic rod is symmetrically arranged with the vertical center line of the main body of the control device as the axis of symmetry.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

Combined with the fitting positioning of the limit rod and the limit socket, it can meet the operating habits and work scenario requirements of different operators. The control display assembly, relying on the connection structure between the first telescopic rod and the supporting base plate, can flexibly adjust its height, allowing operators to more conveniently view displayed information, significantly improving operational comfort and efficiency. Meanwhile, the casters at the bottom of the control device facilitate overall movement, and the symmetrical arrangement of the handrails further enhances stability and convenience during movement, enabling the device to flexibly adapt to different work sites.

[0016] 2.

Combined with the casters, double fixation is achieved, effectively preventing the device from sliding or shifting during operation. The partition plate on the storage shell can orderly separate and store the tools or accessories placed inside, improving space utilization and making them easy to access. The limiting block restricts the range of motion of the limiting sleeve block to prevent the control panel assembly from falling off during adjustment. The connection between the limiting collar and the support base plate enhances the support stability of the control display assembly. The multiple limiting and fixing structures together ensure the reliability and safety of the device during operation. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a grab crane control device, including a control device body 1, a universal wheel 2 fixedly connected to one side of the control device body 1, and a control mechanism 3 installed on the upper surface of the control device body 1;

[0024] The control mechanism 3 includes a storage shell 301, which is mounted on the main body 1 of the control device. A cylindrical limiting rod 303 is fixedly connected to one side of the storage shell 301. A limiting sleeve block 304 is movably connected to one side of the cylindrical limiting rod 303. An operation panel assembly 305 is fixedly connected to one side of the limiting sleeve block 304. A fixing plate 307 is fixedly connected to one side of the storage shell 301. A first telescopic rod 308 is fixedly connected to one side of the fixing plate 307. A support base plate 310 is fixedly connected to one side of the first telescopic rod 308. A control display assembly 311 is fixedly connected to one side of the support base plate 310. A connecting sleeve 315 is fixedly connected to one side of the storage shell 301. A second telescopic rod 316 is fixedly connected to one side of the connecting sleeve 315. A positioning anti-slip plate 317 is fixedly connected to one side of the second telescopic rod 316. A limiting insertion rod 312 is movably connected to one side of the storage shell 301.

[0025] Furthermore, a limiting block 306 is fixedly connected to one side of the cylindrical limiting rod 303, and the limiting block 306 and the limiting sleeve block 304 are matched in size. The limiting block 306 can effectively limit the range of motion of the limiting sleeve block 304 on the cylindrical limiting rod 303, preventing the limiting sleeve block 304 from falling off the cylindrical limiting rod 303, thereby ensuring the stability and safety of the operation panel assembly 305 during the adjustment process and avoiding operation interruption or equipment damage due to component detachment.

[0026] Furthermore, a limiting collar 309 is fixedly connected to one side of the storage shell 301, and the limiting collar 309 is connected to the support base plate 310. The limiting collar 309 can guide and limit the movement trajectory of the support base plate 310 when the height of the support base plate 310 is adjusted by the first telescopic rod 308, preventing the support base plate 310 from shifting or shaking during the adjustment process, and ensuring that the control display assembly 311 always maintains a stable posture, so that the operator can clearly view the display content.

[0027] Furthermore, a limit socket 313 is provided on one side of the control panel assembly 305, and the limit socket 313 and the limit rod 312 are structurally matched. The limit socket 313 and the limit rod 312 are used together to firmly fix the control panel assembly 305 after it is adjusted to a suitable angle, so as to prevent the control panel assembly 305 from shifting its angle due to external force collisions or other reasons during operation, and to ensure the accuracy and continuity of the operator's operation.

[0028] Furthermore, a handrail 314 is fixedly connected to one side of the main body 1 of the control device, and the handrail 314 is symmetrically arranged with the vertical center line of the main body 1 of the control device as the axis of symmetry. The symmetrical handrail 314 makes it easy for the operator to hold it from both sides, and can better control the direction and force when pushing the main body 1 of the control device to move, making the movement of the device more stable and effortless. At the same time, the symmetrical structure also improves the overall aesthetics and structural coordination of the device.

[0029] Furthermore, a partition plate 302 is fixedly connected to one side of the storage shell 301, and there are multiple partition plates 302 that are parallel to each other. The multiple parallel partition plates 302 divide the internal space of the storage shell 301 into multiple independent storage areas, which facilitates the classification and storage of operating tools, accessories and other items. This not only improves space utilization, but also makes it more convenient to retrieve items, reduces the time spent searching for items, and improves work efficiency.

[0030] Furthermore, the support base plate 310 is connected to the fixed plate 307 via the first telescopic rod 308, and the first telescopic rod 308 is symmetrically arranged with the vertical center line of the control device body 1 as the axis of symmetry. The symmetrical first telescopic rod 308 can provide uniform support to the support base plate 310 from both sides, ensuring its force balance when adjusting the height of the support base plate 310, and avoiding tilting of the support base plate 310 due to excessive force on one side, thereby ensuring the stable installation and normal use of the control display assembly 311.

[0031] Working principle: When a user needs to use a grab crane control device, the operator holds the handle 314 on one side of the control device body 1 and pushes the device to the working position using the casters 2 at the bottom; then, the second telescopic rod 316 on one side of the connecting sleeve 315 is activated, extending it and causing the positioning anti-slip plate 317 to contact the ground, thus fixing the device. The limiting rod 312 on one side of the storage shell 301 is pulled to disengage it from the limiting socket 313 on the control panel assembly 305. Through the movable connection between the cylindrical limiting rod 303 and the limiting sleeve block 304, the control panel assembly 305 is rotated to a suitable angle, and then the limiting rod 312 is inserted to fix it. Simultaneously, the height of the support base plate 310 is adjusted by the first telescopic rod 308 on one side of the fixed plate 307, so that the control display assembly 311 is in a position that is easy to view. The limiting collar 309 plays an auxiliary limiting role for the support base plate 310 during this process. The operator controls the operation of the grab crane through the operation panel assembly 305 and the control display assembly 311. The partition plate 302 in the storage shell 301 can be used to classify and place tools. After the operation is completed, the first telescopic rod 308 and the operation panel assembly 305 are adjusted in the opposite direction to the initial position, the second telescopic rod 316 is retracted to make the positioning anti-slip plate 317 leave the ground, and the handrail 314 is pushed to move the device to the storage location.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
