Wheel adjusting device and four-direction carrying vehicle

Abstract

The invention provides a wheel adjusting device and a four-direction carrying vehicle, and relates to the technical field of conveying equipment in warehouse logistics systems. The technical problem that when the carrying vehicle turns between a cargo loading and unloading tunnel and a storage rack tunnel mutually, due to mutual transformation of a lifting wheel and a fixing wheel, a square chassis and cargos arranged in the square chassis need to be moved up and down, and therefore larger driving force is needed for the carrying vehicle is solved. The wheel adjusting device comprises a guideplate and a height driving mechanism, the guide plate is installed on the inner side of a side plate of the four-direction carrying vehicle and fixedly connected with the side plate, the outer side ofthe side plate is provided with a wheel assembly and fixedly connected with the wheel assembly, and the four-direction carrying vehicle comprises the wheel adjusting device. The wheel assembly is independently driven to ascend and descend, overall up-down movement of the square chassis is not caused, the burden on the driving mechanism is reduced, and the production and operation cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of transportation equipment for storage and logistics systems, in particular to a wheel adjusting device and a four-way transport vehicle thereof. Background technique

[0002] With the continuous development of the warehousing industry, higher and higher requirements are put forward for the utilization rate of material flow warehouse space, so that more shelves are arranged on the plane of the warehouse, and more shelf compartments are arranged in the height direction, so as to minimize the entry and exit. The space occupied by the unloading channel becomes the direction of development.

[0003] At present, the three-dimensional warehouse structure model of a loading and unloading lane in the middle of two rows of shelves is gradually developing to a model of a loading and unloading lane and multiple storage rack lanes vertically connected to it. This structural mode greatly reduces the space occupied by t...

Examples

Embodiment 1

[0037] A wheel adjusting device 400 provided by the present invention, such as figure 2 and image 3 As shown, it includes a guide plate 401 and a height driving mechanism 402. The guide plate 401 is installed on the inner side of the side plate 408 of the four-way truck. The guide plate 401 is connected to the side plate 408 by sliding left and right. Slidingly connected with the wheel assembly 300 up and down, the movement of the guide plate 401 drives the movement of the wheel assembly 300, and the lifting track of the wheel assembly 300 is the same as the movement track of the guide plate 401, that is, the upward movement of the guide plate 401 drives the wheel assembly 300 to move upward, guiding The plate 401 moves downward, driving the wheel assembly 300 to move downward, the wheel assembly 300 on the opposite side moves in the same way, and the adjacent wheel assembly 300 moves in the opposite way, so as to realize the conversion of the direction of the four-way truck...

Embodiment 2

[0050] On the basis of Embodiment 1, this embodiment provides a four-way transport vehicle, such as figure 1 As shown, the above-mentioned wheel adjustment device 400 is included, and the wheel drive mechanism 200, the wheel assembly 300 and the square chassis are also included. The side plates 408 are installed on the outer sides of the upper surface of the square chassis to form a loading and unloading space. The wheel assembly 300 is installed under the square chassis. Around the surface, the wheel adjusting device 400 is correspondingly arranged with the wheel assembly 300, the wheel driving mechanism 200 is installed in the inside of the square chassis and the wheel driving mechanism 200 is drivingly connected with the wheel assembly 300 for driving the rolling of the wheel assembly 300 on the walking guide rail 500 .
