Description

Technical Field

[0001] The utility model relates to the technical field of EMS transportation, in particular to an EMS transportation device of a six-car group used for transportation of automobile bodies. Background Art

[0002] EMS conveyor line, the full name of which is Electrified Monorail System Conveyor, uses a single electrically driven trolley to run on a track. It is an efficient automated material handling system, usually used for the transportation of equipment and parts within or between workshops, and is particularly suitable for production environments that require precise positioning and rapid transportation.

[0003] In the final assembly workshop of the automobile main engine factory, the car body is transported by EMS to realize the assembly of the bottom parts of the car body. After the installation is completed, it needs to be transported to the next station for the assembly of the bottom parts of the car body, and finally transported to the offline station. However, with the popularization of new energy electric vehicles, batteries and other components need to be installed on the process assembly line. Due to the large mass of batteries and other components, coupled with the weight of the large hoist itself, the weight of the whole vehicle also increases. Due to the limited carrying capacity of the rubber-coated wheels on the conveyor trolleys on the conventional EMS conveyor line, they are often unable to carry overweight car bodies, which greatly reduces the service life of the rubber-coated wheels and the transportation efficiency of the entire transportation production line.

[0004] Therefore, it is urgent to develop a new type of EMS conveying equipment to better convey automobile bodies and improve the transportation efficiency of automobile bodies. Utility Model Content

[0032] Embodiment 1:

[0033] An EMS conveying device with six trolleys for conveying automobile bodies comprises an EMS conveying track 1 and six conveying trolleys 2 slidably mounted on the EMS conveying track 1. The conveying trolleys 2 each comprise a rubber-coated wheel 3 capable of reciprocating on the EMS conveying track 1.

[0034] The six conveying trolleys 2 are divided into two conveying modules, each of which includes three conveying trolleys 2. In each conveying module, two groups of adjacent conveying trolleys 2 are connected by a first connecting rod 4, and another group of conveying trolleys 2 is connected to the first connecting rod 4 by a second connecting rod 5, and a sling assembly 6 for fixing and grabbing the automobile body is connected between the two second connecting rods 5.

[0035] In this embodiment, the load of the rubber-coated wheel 3 is evenly shared by cooperating with the conveying trolley 2 and the first connecting rod 4 and the second connecting rod 5, which not only prolongs the service life of the rubber-coated wheel 3, but also realizes efficient EMS transportation of the entire six-trolley group.

[0036] Embodiment 2:

[0037] The present embodiment provides a six-cart EMS conveying device for conveying automobile bodies, which includes an EMS conveying track 1 and six conveying carts 2 slidably mounted on the EMS conveying track 1, and the conveying carts 2 each include a rubber-coated wheel 3 that can reciprocate on the EMS conveying track 1. The trolley body of the conveying cart 2 is C-shaped and clamped on the EMS conveying track 1, and the rubber-coated wheels 3 are all arranged in the slide groove of the EMS conveying track 1. The EMS conveying track 1 of the present embodiment is a steel track with an I-shaped cross section, and the rubber-coated wheels 3 are polyurethane rubber-coated wheels 3 commonly used in industry.

[0038] Among them, the six conveying carts 2 are divided into two conveying modules, which are respectively referred to as the first conveying module and the second conveying module in this embodiment, and each conveying module includes three conveying carts 2. The first conveying module includes a group of driving carts 21 and two adjacent groups of driven carts 22, and the second conveying module includes three driven carts 22. Only the driving cart 21 of the first conveying module is connected to an electric drive 23 for driving it to reciprocate along the EMS conveying track 1. The electric drive 23 of this embodiment is a conventional drive motor, the output shaft of the drive motor is connected to the drive cart 21, and the drive motor is connected to a PLC control system.

[0039] In the first conveying module, two groups of adjacent driven trolleys 22 are connected by a first connecting rod 4, and the driving trolley 21 is connected to the first connecting rod 4 by a second connecting rod 5. In the second conveying module, two groups of driven trolleys 22 close to the first conveying module are connected by a first connecting rod 4, and another group of driven trolleys 22 is connected to the first connecting rod 4 by a second connecting rod 5. Both ends of the first connecting rod 4 are respectively installed at the bottom of each conveying trolley 2 by bolt connection. A sling assembly 6 for fixing and grabbing the automobile body is connected between the second connecting rods 5 of the two conveying modules.

[0040] In this embodiment, by separately setting up a driving trolley 21 and cooperating with the first connecting rod 4 and the second connecting rod 5, the remaining five driven trolleys 22 can be driven to reciprocate by driving one driving trolley 21, thereby realizing EMS transportation of the entire six-trolley group.

[0041] Embodiment 3:

[0042] This embodiment provides a six-car EMS conveying device for conveying automobile bodies. The difference from the embodiment 2 is that the sling assembly 6 of this embodiment includes hooks 61 respectively installed on two second connecting rods 5, and a sling 62 clamped between the two hooks 61. The hooks 61 each include a driving lifting motor 611, and the driving lifting motor 611 is connected to a PLC control system, and can be lifted and lowered under the control of the control system. The size of the sling 62 is adapted to the automobile body to better grasp and fix the body and convey it.

[0043] The working principle of the six-car EMS conveying equipment in this embodiment is as follows:

[0044] After the sling 62 firmly grasps the automobile body, the lifting motor 611 is driven to drive the hook 61 to rise. Subsequently, the PLC control system drives the driving trolley 21 to move by controlling the electric drive 23, and drives the remaining five driven trolleys 22 to move back and forth with the cooperation of the first connecting rod 4 and the second connecting rod 5, thereby realizing the EMS transportation of the entire six-trolley group. Through the clever coordination of a driving trolley 21, five driven trolleys 22 and connecting rods, the load of a single rubber-coated wheel 3 can be greatly reduced, and the EMS transportation of the entire six-trolley group can be realized with the cooperation of the sling assembly to improve the transportation efficiency of the automobile body. At the same time, the EMS transportation equipment of the six-trolley group can carry and transport the assembled new energy automobile bodies with heavier weight through reasonable modular settings, which can meet the efficient transportation requirements of heavy automobile bodies on the automobile assembly line.

[0045] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
