Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a vehicle body structure suitable for an ultra-thin shuttle vehicle. Background Art

[0002] As a cargo-carrying device in warehousing and logistics equipment, shuttle vehicles mainly have two forms in warehousing and logistics equipment: shuttle vehicle-type in-and-out storage system and shuttle vehicle-type storage system. The trolleys run on fixed tracks in a reciprocating or looping manner to transport goods to designated locations or docking equipment. Equipped with an intelligent sensing system, it can automatically memorize the origin position and automatically decelerate the system.

[0003] When it is necessary to install a lifting mechanism on the shuttle car, the existing traditional shuttle car lifting mechanism mainly adopts a hydraulic system or an electric screw mechanism, in which the hydraulic system drives the hydraulic cylinder through hydraulic oil to realize the function of lifting and lowering the cargo platform. Its advantages are strong load-bearing capacity and suitability for large cargo platforms; relatively stable operation; and the ability to work under high load and high altitude conditions. However, the hydraulic system may require more maintenance and care; the system is highly complex, and installation and debugging require professional skills, and the cost itself is too high.

[0004] The electric screw mechanism uses an electric motor to drive the screw, and the nut moves along the screw to raise or lower the cargo platform. However, in actual use, the load-bearing capacity may be lower than that of the hydraulic system; the speed is generally slow, and it is not suitable for applications that require high-speed lifting.

[0006] The shuttle vehicle disclosed above achieves the lifting effect of the shuttle vehicle by raising and lowering the lifting guide block on the lifting base. However, since the lifting base is always in a relatively static state, and since the lifting base needs to limit and guide the lifting guide block during the lifting process, the lifting base must have a certain height. This height affects the overall lifting range of the lifting assembly and affects the overall thickness of the shuttle vehicle. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0027] As shown in Figures 1-6As shown in the figure, a vehicle body structure applicable to an ultra-thin shuttle car includes a vehicle body base 1 and at least two lifting devices 2 installed side by side in the vehicle body base 1; a lifting plate 3 lifted by the lifting device 2 is installed on the top of the lifting device 2, a guiding plate 11 for guiding the lifting plate 3 is formed on the vehicle body base 1, and a limiting vertical plate 12 for limiting and abutting the lifting plate 3 is formed on the side of the vehicle body base 1; the lifting device 2 is composed of at least two lifting seats 4, and the lifting seat 4 includes a top connecting seat 41, a lifting main body 42, and a bottom connecting seat 43 that are hinged in sequence from top to bottom. The top connecting seat 41 is fixedly connected to the lifting plate 3, the bottom connecting seat 43 is fixedly connected to the vehicle body base 1, the lifting main body 42 is composed of two hinged lifting arms 44, and the ends of the two lifting arms 44 are overlapped and hinged.

[0028] The number of the lifting devices 2 is set according to actual needs. The lifting devices 2 in the vehicle body base 1 are always in a side-by-side state. Therefore, the ends of the multiple lifting devices 2 in the vehicle body base 1 are flush, which is convenient for realizing the synchronous driving of the multiple lifting devices 2 under the action of the crank-link structure on the same rotating shaft.

[0029] Two side-by-side lifting devices 2 are installed on the vehicle body base 1, and the two lifting devices 2 are respectively installed at the opposite sides of the vehicle body base 1. The two lifting devices 2 are always in a synchronous lifting state. Thus, the same lifting plate can be placed on the two lifting devices 2, and the goods can be placed on the lifting plate. The lifting of the goods is driven by the lifting of the lifting plate.

[0030] Two guiding plates 11 arranged oppositely are formed on the vehicle body base 1. The two guiding plates 11 are respectively arranged at the opposite ends of the lifting plate 3, and two limiting vertical plates 12 arranged oppositely are formed on the vehicle body base 1. The two limiting vertical plates 12 respectively correspond to the two lifting plates 3 one by one.

[0031] The two guiding plates 11 are arranged in parallel. Under the action of the guiding plates 11, it is ensured that during the lifting process of the lifting plate 3, both ends of the lifting plate 3 are always in contact with the two guiding plates 11 simultaneously. Thus, under the action of the two guiding plates 11, the guiding of the lifting plate 3 during the lifting process is realized, and further, a certain supporting effect on the lifting main body 42 is achieved.

[0032] The two guiding plates 11 and the two limiting vertical plates 12 are sequentially connected to form a frame-shaped structure. An installation cavity 13 for installing the lifting device 2 is formed in the middle of the frame-shaped structure. The installation cavity 13 is a sunken structure formed in the middle of the vehicle body base 1. The lifting device 2 is installed in the installation cavity 13. The guiding plates 11 and the limiting vertical plates 12 are arranged around the lifting device 2, and the guiding plates 11 and the limiting vertical plates 12 can play a role in protecting the lifting device 2.

[0033] The guide plate 11 and the limit vertical plate 12 are vertically arranged upward on the vehicle body base 1. The guide plate 11, the limit vertical plate 12 and the vehicle body base 1 are of an integral structure to ensure the overall structural strength of the vehicle body. The vertically arranged guide plate 11 and limit vertical plate 12 play a role in surrounding protection for the lifting device 2.

[0034] The lifting plate 3 includes a lifting main body 31, two matching guide plates 32 and two matching vertical plates 33. The two matching guide plates 32 are vertically arranged at opposite ends of the lifting main body 31, and the matching guide plates 32 are arranged corresponding to the guide plate 11. The two matching vertical plates 33 are vertically arranged on opposite sides of the lifting main body 31, and the limit vertical plate 12 is located between the two matching vertical plates 33.

[0035] The lifting main body 31, the two matching guide plates 32 and the two matching vertical plates 33 are of an integral structure to ensure the overall structural strength of the lifting plate 3. Under the action of the lifting device 2, the lifting of the lifting main body 31 is realized, thereby driving the synchronous lifting and lowering of the matching guide plates 32 and the matching vertical plates 33.

[0036] During the lifting and lowering process of the matching guide plate 32, the matching guide plate 32 abuts against the guide plate 11. And through the setting of the matching guide plate 32, it is used to increase the contact area between the lifting plate 3 and the guide plate 11 to ensure the guiding effect of the guide plate 11 on the lifting plate 3.

[0037] The two matching guide plates 32 and the two matching vertical plates 33 are sequentially connected to form a frame structure, and the lifting device 2 is fixedly connected to the lower surface of the lifting main body 31.

[0038] Under the action that the limit vertical plate 12 is located between the two matching vertical plates 33, when the lower surface of the lifting main body 31 descends to a certain height, the lower surface of the lifting main body 31 abuts against the limit vertical plate 12. Under the action of the limit vertical plate 12, the lowest height of the lifting plate 3 is limited, thereby reducing the force on the lifting main body 42 at the lowest position of the lifting plate 3.

[0039] The matching guide plates 32 and the matching vertical plates 33 are vertically arranged downward on the lifting main body 31.

[0040] A connecting rod assembly 5 for synchronously controlling the lifting of at least two lifting seats 4 is installed on the lifting device 2. A push-pull shaft 6 for pushing and pulling the connecting rod assembly 5 is provided at the end of the connecting rod assembly 5. The push-pull shaft 6 can be connected to a crank connecting rod structure to realize the reciprocating push-pull operation of the connecting rod assembly 5, thereby controlling the lifting of the lifting main body 42.

[0041] One of the lifting seats 4 is connected with a lateral support seat 7. The lateral support seat 7 and the push-pull shaft 6 are arranged on opposite sides of the lifting seat 4. The lateral support seat 7 is used to support the lateral force of the lifting main body 42 and support the lifting structure of the lifting main body 42.
