Fig. 1 shows a schematic structural diagram of an electrically controlled omni-directional mobile gantry apparatus according to an embodiment of the present invention. Fig. 2 is a side schematic view of fig. 1. As shown in the figure, an electrically controlled omni-directional mobile gantry crane apparatus 100 mainly includes an electric chassis 101, a gantry support 102, an electric hoist 104, and a mecanum wheel set.

Wherein, the gantry support 102 is fixedly arranged on the electric chassis 101. The gantry 102 includes a guide rail 103 disposed in a horizontal direction on the top thereof.

The electric hoist 104 is arranged on the guide rail 103 of the gantry support 102, and the electric hoist 104 is used for hoisting goods.

The mecanum wheel sets are disposed at the bottom of the motorized chassis 101. The Mecanum wheel set is compact in structure and flexible in movement, and is an omnidirectional wheel. The wheels at all positions are combined, so that the functions of translation and the like around can be realized more flexibly and conveniently.

According to the electric control all-directional movable type gantry crane device 100, a gantry crane and Mecanum wheels 105 are combined, the movement and hoisting transportation in a narrow space can be guaranteed, the whole operation is convenient, the working efficiency is effectively improved, and the safety risk is reduced due to flexible movement.

Preferably, the mecanum wheel set includes a plurality of mecanum wheels 105 and a plurality of load bearing springs 106, the load bearing springs 106 are disposed in a vertical direction, and the mecanum wheels 105 are disposed at the bottom of the power chassis 101 through the load bearing springs 106. In this embodiment, 4 Mecanum wheels 105 and 4 load bearing springs 106 are included, with the Mecanum wheels 105 and load bearing springs 106 corresponding one-to-one. It is easy to understand that when the electric hoist 104 lifts a cargo, the load-bearing spring 106 is deformed under compression under different loads, so that the distance between the electric chassis 101 and the ground is changed. It should be noted that a plurality of small rollers are diagonally distributed on the rim of each mecanum wheel 105, the generatrices of the small rollers are very specific, and when the wheel rotates around a fixed wheel spindle, the envelope curve of each small roller is a cylindrical surface, so that the wheel can continuously roll forward.

Preferably, the electrically controlled omni-directional mobile gantry crane apparatus 100 further comprises a plurality of wheel driving motors 107, the number of which is equivalent to the number of mecanum wheels 105 and load bearing springs 106. In the present embodiment, 4 wheat wheel driving motors 107 are provided, and the wheat wheel driving motors 107 are used for driving the Mecanum wheel 105 to rotate. The wheat wheel driving motor 107 is arranged at the bottom of the bearing spring 106, and the top of the bearing spring 106 is fixed on the electric chassis 101.

Preferably, the electrically controlled omni-directional mobile gantry crane apparatus 100 further comprises a bearing wheel set. The load bearing wheel set includes a plurality of load bearing support columns 108 and a plurality of load bearing universal wheels 109. The load bearing support column 108 is disposed in a vertical orientation.

Fig. 3 is a partial schematic view of the electrically controlled omni-directional mobile gantry apparatus of fig. 1 in a light load state. Fig. 4 is a partial schematic view of the electrically controlled omni-directional mobile gantry apparatus of fig. 1 under a heavy load condition. Preferably, the electrically-controlled omni-directional mobile gantry crane apparatus 100 is under light load, and referring to fig. 3, the bottom surface of the load-bearing universal wheel 109 is higher than the bottom surface of the mecanum wheel 105 in the vertical direction. Because of light load, the loaded weight is transmitted to the bearing spring 106 through the electric chassis 101, the bearing spring 106 is less deformed under pressure, the distance between the electric chassis 101 and the ground is larger, the bottom surface of the bearing universal wheel 109 is not contacted with the ground, and the bearing universal wheel is independently supported by the Mecanum wheel 105. In the heavy-load state, referring to fig. 4, the bottom surface of the load-bearing universal wheel 109 is flush with the bottom surface of the mecanum wheel 105. Because of heavy load, the loaded goods and the weight of the electric chassis 101 are transmitted to the bearing spring 106, the bearing spring 106 is pressed to be enlarged, and the distance between the electric chassis 101 and the ground is gradually reduced until the bottom surface of the bearing universal wheel 109 is contacted with the ground. The load-bearing universal wheels 109 and the mecanum wheels 105 together bear load and can bear greater weight. As will be readily appreciated, the load bearing wheel sets are used to provide additional support. Preferably, a positioning column 110 is further disposed at the bottom of the electric chassis 101, and the bearing spring 106 is sleeved on the positioning column 110 to prevent the bearing spring 106 from deflecting under pressure, thereby improving safety performance.

Preferably, the height of the load bearing support column 108 is adjustable to adjust the maximum gravitational component that the mecanum wheels 105 need to support on the ground. Once this gravitational component is exceeded, additional support is provided by the load-bearing universal wheels 109 landing on the ground.

Preferably, the distance between the load bearing support column 108 and the load bearing spring 106 is adjustable.

Preferably, the electric hoist 104 can move in the length direction of the guide rail 103, so as to conveniently lift the goods. Preferably, the electrically controlled omni-directional mobile gantry crane apparatus 100 further includes a crane cable 111 and a crane hook 112 disposed on the electric hoist 104, and the crane hook 112 is hung under the electric hoist 104 through the crane cable 111.

Preferably, the electrically controlled omni-directional mobile gantry crane apparatus 100 further comprises a controller (not shown). The controller sends control signals to mecanum wheel 105 in a wired or wireless manner for controlling the rotational speed of mecanum wheel 105. The controller may be located on the electric chassis 101 and connected to the motor drive 107 to provide wired signals. The controller may also be provided in the control room and send to the wheat wheel drive motor 107 via a wireless signal. The controller implements different rotational speed control for each mecanum so that the electric chassis 101 can move forward, or move forward, backward, leftward and rightward, or rotate in place by 360 degrees.

The utility model designs an electric control omnibearing movable gantry crane device, which adopts Mecanum wheels as movable wheels, and a bearing universal wheel is used for auxiliary support, so that the whole load is heavy, the movement is flexible, and the gantry crane device can rotate 360 degrees in situ, obliquely upwards and downwards, and horizontally move front and back and left.
