[0002] RGV (Automated Guided Vehicle) carts are automated material handling equipment that run along fixed tracks and are widely used in high-density warehousing, logistics sorting, and production line material conveying scenarios.

[0003] Existing technology discloses a height-adjustable RGV trolley transport device (publication number CN211365989U). The transport device includes an RGV trolley, a trolley track that cooperates with the RGV trolley, and a roller conveyor line mounted on the trolley track via a height-adjustable lifting device. The lifting device is an electro-hydraulic lift, which includes a top plate and a bottom plate. The top plate and bottom plate are connected on both sides by "X"-shaped brackets, and the intersection of the two "X" brackets is connected by a crossbar. An electro-hydraulic rod is installed between the crossbar and the bottom plate. This height-adjustable RGV trolley transport device has a wide range of applications, mainly used in automation and logistics industries, for the efficient and stable transport and distribution of workpieces, tooling plates, material boxes, cartons, and other goods at designated positions and heights.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A height-adjustable RGV trolley transport device includes a mobile device 1 and a carrier body 2. A transport frame 3 is bolted to the top surface of the carrier body 2, and metal plates 4 are fixedly connected to the left and right ends of the top of the carrier body 2. The carrier body 2 is installed on the top of the mobile device 1.

[0028] The mobile device 1 includes a metal horizontal plate 11, a lifting assembly 13 is welded to the top surface of the metal horizontal plate 11, and mobile wheels 12 are welded to the front and rear ends of the bottom surface of the lifting assembly 13.

[0029] The lifting assembly 13 includes a rail-guided vehicle body 137, and a carrier vehicle body 2 is installed on the top surface of the rail-guided vehicle body 137. The rail-guided vehicle body 137 transports the carrier vehicle body 2 by moving wheels 12, which facilitates the adjustment of the position of the rail-guided vehicle body 137 and the transport frame 3.

[0030] Connectors 138 are welded to the left and right sides of the bottom of the rail-guided vehicle body 137. L-shaped metal plates 132 are bolted to the left and right ends of the bottom of the rail-guided vehicle body 137. A groove is opened at the bottom of the rail-guided vehicle body 137. The depth of the groove is the same as the thickness of the L-shaped metal plate 132. The rail-guided vehicle body 137 and the L-shaped metal plate 132 are bolted together, which facilitates the disassembly and replacement of the L-shaped metal plate 132 and increases the service life of the L-shaped metal plate 132.

[0031] An electric push rod 131 is bolted to one of the outward ends of the L-shaped metal plate 132. There are four electric push rods 131 in total. Two electric push rods 131 form a group, and the two groups of electric push rods 131 are distributed on the left and right sides of the top surface of the metal horizontal plate 11. Two electric push rods 131 on the same side are distributed at the front and rear ends of the metal plate 4. The metal horizontal plate 11 and the metal plate 4 determine the position of the electric push rods 131. The four electric push rods 131 are controlled by a PLC controller.

[0032] An insert rod 136 is inserted into the top of the piston rod inside the electric push rod 131. The metal plate 4 is installed on the top of the electric push rod 131. The insert rod 136 is inserted into the outward end of the metal plate 4. The insert rod 136 is inserted into the connection between the metal plate 4 and the electric push rod 131, which makes it easy to detach the electric push rod 131 from the metal plate 4 and maintain the stability of the supporting vehicle body 2.

[0033] A metal shell 134 is welded to the inner end of the L-shaped metal plate 132. The moving wheel 12 is welded to the bottom surface of the rail-guided vehicle body 137. The metal cross plate 11 is welded to the bottom surface of the rail-guided vehicle body 137. The metal cross plate 11 is connected to the bottom surface of the L-shaped metal plate 132. The metal cross plate 11 and the L-shaped metal plate 132 are connected to prevent the L-shaped metal plate 132 from shaking and to maintain the stability of the L-shaped metal plate 132.

[0034] Limiting blocks 133 are inserted into the front and rear ends of the metal casing 134. A threaded rod 135 is inserted into the inner wall surface of the limiting block 133. The limiting block 133 is inserted into the outward end of the connector 138. The limiting block 133 is slidably connected to the surface of the threaded rod 135. The threaded rod 135 is inserted into the inner wall surface of the metal casing 134. The threaded rod 135 maintains the stability of the limiting block 133 and facilitates the adjustment of the stability of the limiting block 133.

[0035] When in use, pulling the plug rod 136 disengages the plug rod 136 from the electric push rod 131 and the metal plate 4, thus loosening the connection between the electric push rod 131 and the metal plate 4.

[0036] Rotate the nut, and the nut will rotate on the surface of the limit plug 133, loosening the connection between the limit plug 133 and the connector 138.

[0037] Pull the limiting plug 133 to slide on the inner wall surface of the metal shell 134, and at the same time, the limiting plug 133 slides on the surface of the threaded rod 135, and the limiting plug 133 disengages from the connector 138 and the metal shell 134.

[0038] Rotate the bolt, and the bolt will disengage from the rail-guided vehicle body 137 and the L-shaped metal plate 132. The connection between the L-shaped metal plate 132 and the rail-guided vehicle body 137 will become loose. Pull the L-shaped metal plate 132 outward, and the L-shaped metal plate 132 will slide on the top surface of the metal cross plate 11.

[0039] When the L-shaped metal plate 132 moves, it can drive the electric push rod 131 to move outward, which facilitates the maintenance of the L-shaped metal plate 132 and the electric push rod 131 and increases the service life of the L-shaped metal plate 132 and the electric push rod 131.

[0040] The rail-guided vehicle body 137 is started, and the rail-guided vehicle body 137 drives the moving wheels 12 to slide on the surface of the track, which makes it easy to adjust the position of the rail-guided vehicle body 137 and move the transport frame 3, making the transportation of materials inside the transport frame 3 more convenient.

[0041] The front of the carrier body 2 is equipped with an operation panel. When the operation panel is activated, four electric push rods 131 are activated. The piston rod inside the electric push rods 131 pushes the metal plate 4 to move upward, and the metal plate 4 drives the carrier body 2 to move upward.

[0042] The carrier body 2 pushes the transport frame 3 upward to adjust the position of the transport frame 3, making it easier to place transport materials into the transport frame 3.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
