[0002] The overhead crane dispatching and commanding instrument is a multifunctional communication device that integrates wireless communication, alarm and broadcast functions. It can solve the communication problems between overhead crane operators and on-site ground command personnel, improve work efficiency and protect the safety of equipment and personnel in on-site operations. The device can also be used for on-site dispatching and command departments to command, communicate and convey information to operators on coke pushing and blocking car travel equipment in the metallurgical industry.

[0003] Chinese patent publication CN210469468U discloses a crane dispatching and commanding instrument, comprising a main unit, a speaker, a microphone, and an antenna. The main unit has a control panel and a wiring panel positioned relative to each other.

This technical solution not only facilitates operation, but also improves call quality and achieves efficient information transmission. It can be widely used by metallurgical site dispatching and command departments to command, communicate, and exchange information with operators of traveling equipment such as cranes, pushers, and coke interceptors.

[0004] However, the above technical solution has the following shortcomings: when using the commander to communicate with operators of equipment such as overhead cranes, the user needs to move the commander to the corresponding position according to the point where command is required, or set up multiple commanders to cover the interior of the factory, and the user needs to overlook the site from a higher point to facilitate viewing the specific distribution of items.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

DETAILED DESCRIPTION

[0019] Example 1

[0020] like Figure 1-Figure 4 As shown, a crane dispatching controller proposed in this embodiment includes a base frame 1 and a top frame 4. A moving assembly 2 is provided at the bottom of the base frame 1. The moving assembly 2 has a self-locking component to prevent the controller from moving freely after being moved into position and causing injury to other pedestrians; the top frame 4 is provided with a controller 5, a folding ladder assembly 7 and a plurality of guardrails 6. A lifting assembly 3 is provided between the base frame 1 and the top frame 4. The lifting assembly 3 includes a motor 31 provided on the base frame 1, a bidirectional screw rod 32 rotatably provided on the base frame 1, two drive frames 33 relatively slidably provided on the base frame 1, a pair of mounting rings 37 provided on each of the two drive frames 33, a plurality of ball bearings 38 arranged in a ring shape between the mounting rings 37 and the drive frames 33, a plurality of lifting rods 34 rotatably provided on the two pairs of mounting rings 37, a connecting rod 35 provided on the lifting rod 34, and a roller 36 provided on the connecting rod 35. The roller 36 is in rolling contact with the top frame 4. The motor 31 is drive-connected to the bidirectional screw rod 32, and the drive frame 33 is threadedly connected to the bidirectional screw rod 32.

[0021] When using this embodiment, the user moves the base frame 1 to a position suitable for user scheduling through the moving component 2, and then the user moves to the top frame 4 through the folding ladder component. The guardrail 6 can prevent the user from falling from the top frame 4 due to inattention, thereby ensuring the user's personal safety. Then, the motor 31 is driven according to the user's needs. The motor 31 drives the driving frame 33 to move toward each other through the bidirectional screw rod 32, and multiple lifting rods 34 rotate to drive the top frame 4 to move upward, so that the user can reach a height that he or she is satisfied with, expands the user's field of view, and does not need to move to the side of the goods to schedule the overhead crane, thereby reducing the user's workload.

[0022] Example 2

[0023] like Figure 2 and Figure 3 As shown, the present embodiment proposes a crane dispatching and controlling instrument. Compared with the first embodiment, in the present embodiment, the driving frame 33 includes a driving block portion 331, a mounting rod 332 provided at each end of the driving block portion 331, a movable frame portion 333 provided on each of the two mounting rods 332, and a roller portion 334 rotatably provided on the movable frame portion 333, and the roller portion 334 is in rolling contact with the base frame 1.

[0024] In this embodiment, when the motor 31 drives the bidirectional screw rod 32 to rotate, the driving block portion 331 moves driven by the bidirectional screw rod 32, and the roller portion 334 on the movable frame portion 333 rolls on the base frame 1, thereby reducing the friction between the driving frame 33 and the base frame 1 and improving the smoothness of the lifting and lowering of the top frame 4.

[0025] Example 3

[0026] like Figure 1 and Figure 4 As shown, this embodiment proposes an overhead crane dispatching and control device. Compared to the first embodiment, in this embodiment, the folding ladder assembly includes multiple overlapping assemblies that are sequentially rotatably connected to the top frame 4, a damping telescopic rod 75 that is rotatably mounted on the bottom frame 1, and a grounding assembly that is rotatably mounted on the overlapping assemblies. The overlapping assemblies include two pairs of continuous curved frames 71 and damping footrests 72 that are rotatably mounted between the two pairs of continuous curved frames 71. Each pair of continuous curved frames 71 is rotatably connected to each other. The footrests 72 have an anti-slip texture. The grounding assembly includes two curved rods 73 that are rotatably mounted on the overlapping assemblies, and a support frame 74 that is rotatably mounted on the two curved rods 73.

[0027] When using this embodiment, the user pulls one of the overlapping components to move it downward, so that the support frame 74 contacts the ground. The multiple continuous bending frames 71 are all continuous bending rods, so that when the multiple continuous bending frames 71 are rotated and connected in sequence, the stability of the folding ladder assembly 7 is increased, allowing the folding ladder assembly 7 to withstand a greater downward pressure of gravity.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
