[0024] The present invention provides a double-station chain-type RGV trolley as shown in Figures 1-5 and includes:

[0025] The trolley body 100 is fixedly connected to the top of the trolley body 101. A control button 102 is provided at one end of the trolley frame 101. The control button 102 includes a start button and an emergency stop button. Both ends of the trolley frame 101 are provided with a three-color light 103, which can serve as a warning.

[0026] The conveying mechanism 200 includes a chain conveyor 201 fixedly connected to both ends of the top of the trolley body 100, the chain conveyor 201 includes a conveyor frame 2011, a transmission shaft 2012 rotatably connected between the conveyor frames 2011 and a sprocket 2013 keyed to the transmission shaft 2012, the two corresponding sprockets 2013 are connected by a chain 2014, a support 2015 for supporting the chain 2014 is fixed between the two sprockets 2013, the support 2015 is a strip plate structure and a U-shaped structure in longitudinal section, the support 2015 is fixed to the top of the crossbeam connecting the two conveyor frames 2011, and can provide support for the chain 2014 to prevent it from bending under pressure, thereby ensuring the stability of the carrier during transportation, and the chain 2014 is fixedly connected to the chain 2014. It is connected to a number of chain plates 2016, which are in contact with the carrier through the chain plates 2016, thereby increasing the contact area, enabling the carrier to be transported smoothly and preventing the chain from causing wear to the bottom of the carrier. A connecting plate 2017 is fixed to the bottom of the conveyor frame 2011, and a driving motor 2018 is fixed to the bottom of the connecting plate 2017. The driving motor 2018 is connected to a sprocket wheel 2020 key-connected to any one of the transmission shafts 1 2012 through a chain 2019, thereby driving the transmission shaft 1 2012 and the chain 1 2014 to move, thereby realizing the transportation of the carrier. A supporting wheel 2021 is fixed to the middle of the transmission shaft 1 2012, and the supporting wheel 2021 is a nylon wheel, which can support the entire chain conveyor 201. The chain conveyor 201 is also provided with a sensor for detecting whether there is cargo.

[0027] In addition, a traveling mechanism 300 is also included, and the traveling mechanism 300 includes traveling wheel assemblies 301 fixed at the four corners of the bottom of the trolley body 100 .

[0028] Specifically, the walking wheel assembly 301 includes a mounting seat 3011 fixedly connected to the trolley body 100 and a walking wheel 3012 rotatably connected to the mounting seat 3011. The two walking wheels 3012 located at the same end of the trolley body 100 are connected through a transmission shaft 2 3013 and a reduction motor 3014. The reduction motor 3014 drives the walking wheels 3012 to rotate through the transmission shaft 2 3013, thereby driving the trolley body 100 to move. Guide wheels 3015 are provided on the two mounting seats 3011 located on the same side of the trolley body 100, which can guide and limit the operation of the trolley body 100 and prevent the trolley body 100 from deviating during operation.

[0029] It is worth mentioning that it also includes a collision prevention block 400. The collision prevention block 400 is inserted and fixed on one side of the mounting seat 3011. The material of the collision prevention block 400 is rubber, which can play a role in buffering and absorbing impact force, reducing the damage caused when the trolley main body 100 collides.

[0030] Specifically, it also includes a guide rail 500. The guide rail 500 is arranged directly below the traveling mechanism 300. The traveling wheels 3012 are in contact with the upper surface of the guide rail 500, and the guide wheels 3015 are in contact with the side surface of the guide rail 500, ensuring that the trolley main body 100 can run along the guide rail 500.

[0031] It should be noted that baffles 501 are fixed at both ends of the guide rail 500, which can block the trolley main body 100 and prevent it from derailing.

[0032] Specifically, there are two chain plate conveyors 201 in total. The two chain plate conveyors 201 operate independently. The conveying direction of the chain plate conveyor 201 is perpendicular to the running direction of the trolley main body 100, which can realize simultaneous connection and conveying at two workstations, with higher efficiency.

[0033] Working principle: When this double-station chain plate type RGV trolley is in use, first, according to the instructions received from the upper system, it runs to the connection station to connect the goods on the conveyor. When the goods fall into the workstations on the trolley, the sensors on the chain plate conveyor 201 detect the goods, and then the trolley main body 100 starts to run. When the trolley runs to the designated position, the chain plate conveyor 201 starts to run. The driving motor 2018 drives the transmission shaft one 2012 to rotate through the chain two 2019 and the sprocket two 2020. The transmission shaft one 2012 drives the chain plate 2016 to rotate through the chain one 2014 and the sprocket one 2013, and then conveys the goods to the connection workstation. This double-station chain plate type RGV trolley has an advanced design, a compact structure, and is convenient to use. By setting two chain plate conveyors 201 on the top of the trolley main body 100, it realizes simultaneous connection and conveying at two workstations, greatly improving the conveying efficiency. By adopting the chain plate design, the contact area is increased, making the operation of the carrier more stable and reliable.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
