Description

Technical Field

[0001] This utility model belongs to the field of RGV (RGV vehicle) technology, specifically relating to a chain-type RGV with the same conveying direction and running direction. Background Technology

[0002] RGV is an abbreviation for Rail-Guided Vehicle, also known as a rail-guided shuttle. RGVs can be used in warehouses with various high-density storage methods. The aisles of the RGVs can be designed to any length, increasing the overall storage capacity of the warehouse. Furthermore, they eliminate the need for forklifts to enter the aisles during operation, thus enhancing safety. RGVs are commonly used in logistics and warehousing areas in real-world production, effectively reducing the labor intensity of workers. After transporting goods to the designated location, the goods need to be unloaded from the RGV. The conveying methods include roller conveyors and chain conveyors. Most RGVs on the market have the transport direction perpendicular to the conveying direction, but some applications require RGVs with the transport direction in the same direction as the conveying direction.

[0003] For RGVs with the same transport and conveying directions, positioning deviations can easily occur between the RGV and the conveyor during interaction. Excessive or insufficient distance can lead to poor cargo handling and pallet damage. Therefore, there is an urgent need to design a chain-type RGV with the same conveying and running directions to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a chain-type RGV with the same conveying direction and running direction, so as to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chain-type RGV with the same conveying direction and running direction, comprising:

[0006] The RGV includes a frame, a cover fixedly fitted onto the frame, and a conveying mechanism and a transport mechanism disposed within the cover. The conveying mechanism includes a geared motor, a conveying chain, a drive shaft, and a chain mounting bracket. There are two chain mounting brackets, which are parallel to each other and embedded in the top of the cover. The conveying chain is driven by the chain mounting bracket. The geared motor is connected to the drive shaft via the drive chain. Both ends of the drive shaft are connected to the conveying chain via sprockets.

[0008] The chain conveyor includes two chain conveyors, which are respectively located at both ends of the ground rail module. Each chain conveyor includes a support frame, a second chain mounting frame fixed to the top of the support frame, and a second conveying chain driven by the second chain mounting frame. There are two second chain mounting frames, which are parallel to each other and the distance between them is greater than the distance between the two first chain mounting frames.

[0009] Furthermore, the transport mechanism includes a second reduction motor fixed to the bottom of the frame and four wheels located at the four corners of the frame. The second reduction motor is connected to the wheels via a second transmission shaft.

[0010] Furthermore, the top of the vehicle cover is provided with a tray, and the bottom of the tray is provided with at least three support blocks, each of which is provided with two rectangular openings.

[0011] Furthermore, the ground track module also includes a laser rangefinder, which includes a laser transmitter and a laser receiver. The laser transmitter is located at one end of the track, and the laser receiver is located on one side of the vehicle cover. The central axes of the laser transmitter and the laser receiver coincide.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] This utility model provides, for example Figure 1-6 The chain-type RGV shown here, with the conveying direction and running direction being the same, includes:

[0027] RGV100 includes a frame 101, a cover 102 fixedly sleeved on the frame 101, and a conveying mechanism 103 and a transport mechanism 104 disposed within the cover 102. The conveying mechanism 103 includes a geared motor 1031, a conveying chain 1032, a drive shaft 1033, and a chain mounting bracket 1034. There are two chain mounting brackets 1034, which are parallel to each other and embedded in the top of the cover 102. The conveying chain 1032 is driven by the chain mounting bracket 1034. The geared motor 1031 is connected to the drive shaft 1033 via a drive chain 1035. The two ends of the drive shaft 1033 are connected to the conveying chain 1032 via sprockets.

[0028] The ground rail module 200 includes a rail 201 and a support 202 fixed to the bottom of the rail 201. Anti-collision blocks 203 are provided at both ends of the rail 201. The RGV100 reciprocates on the top of the rail 201.

[0029] There are two chain conveyors 300, which are respectively set at both ends of the ground rail module 200. Each chain conveyor 300 includes a support frame 301, a chain mounting frame 302 fixed to the top of the support frame 301, and a conveyor chain 3021 driven by the chain mounting frame 302. There are two chain mounting frames 302, which are parallel to each other and the distance between them is greater than the distance between the two chain mounting frames 3034.

[0030] For example, see Figure 4 As shown, the transport mechanism 104 includes a second geared motor 1041 fixed to the bottom of the frame 101 and a traveling wheel 1042 disposed at the four corners of the frame 101. The second geared motor 1041 is connected to the traveling wheel 1042 through a second transmission shaft 1043.

[0031] In this technical solution, the second geared motor 1041 drives the second transmission shaft 1043 to rotate, and the second transmission shaft 1043 drives the walking wheel 1042 to rotate, thereby providing power support for the RGV100 to run along the track 201.

[0032] For example, see Figure 3 As shown, the top of the vehicle cover 102 is provided with a tray 105, and the bottom of the tray 105 is provided with at least three support blocks 1051, each support block 1051 having two rectangular openings 1052.

[0033] In this technical solution, the support block 1051 can better support the pallet 105 and the goods. The rectangular opening 1052 on the support block 1051 can reduce the weight of the support block 1051 and make it easier for forklifts to insert and pick up the pallet 105.

[0034] For example, see Figure 2 and Figure 5 As shown, the ground rail module 200 also includes a laser rangefinder 204, which includes a laser transmitter 2041 and a laser receiver 2042. The laser transmitter 2041 is located at one end of the track 201, and the laser receiver 2042 is located on one side of the cover 102. The central axes of the laser transmitter 2041 and the laser receiver 2042 coincide.

[0035] In this technical solution, the distance between RGV100 and one end of track 201 can be calculated by measuring the time from when the laser is emitted from the laser emitter 2041 to when the laser is received by the laser receiver 2042.

[0036] For example, see Figure 5As shown, the ground rail module 200 also includes a sliding contact line 205, which includes a sliding rail 2051 and a current collector 2052. The sliding rail 2051 is fixed to one side of the rail 201 and connected to the power supply. The current collector 2052 is slidably connected to the sliding rail 2051 and connected to each electrical appliance.

[0037] In this technical solution, the current collector 2052 can draw power from the sliding rail 2051 and supply it to various electrical appliances, thus providing convenient power support for the moving electrical appliances.

[0038] For example, see Figure 6 As shown, the chain conveyor 300 also includes a power mechanism 303 fixed to the bottom of the chain mounting bracket 302. The power mechanism 303 includes a power box 3031 and a geared motor 3032 and a drive shaft 3033 installed in the power box 3031. The geared motor 3032 is connected to the drive shaft 3033 via the drive chain 3034. The two ends of the drive shaft 3033 are connected to the conveyor chain 3021 via sprockets.

[0039] In this technical solution, the geared motor 3032 can drive the transmission shaft 3033 to rotate, which in turn drives the conveyor chain 3021 to move. The conveyor chain 3021 can drive the goods on it to move, which facilitates the transport of goods to the RGV100 and also facilitates the receipt of goods transported by the RGV100.

[0040] For example, see Figure 1 and Figure 6 As shown, a guide plate 304 is provided on one side of the chain mounting bracket 302, and a blocking cable 305 is provided at one end of the chain mounting bracket 302.

[0041] In this technical solution, the guide plate 304 can guide the goods during the transportation process to prevent the goods from deviating or falling off during the transportation process, and the blocking cable 305 can block the goods transported to one end of the chain mounting frame 302 to prevent them from falling off.

[0042] Working principle: When using this chain-type RGV with the same conveying direction and running direction, firstly, the second geared motor 1041 is started. The second geared motor 1041 drives the second drive shaft 1043 to rotate, which in turn drives the walking wheel 1042 to rotate. When the RGV 100 moves to the designated position, the brake is engaged by the second geared motor 1041. Then, the first geared motor 1031 and the third geared motor 3032 are started simultaneously. The first geared motor 1031 drives the first drive shaft 1033 to rotate through the first drive chain 1035, which in turn drives the walking wheel 1042 to rotate. The sprockets at both ends of the drive shaft 1033 drive the conveyor chain 1032 to move. The geared motor 3032 drives the drive shaft 3033 to rotate through the drive chain 2 3034. In turn, the sprockets at both ends of the drive shaft 3033 drive the conveyor chain 2 3021 to move. The goods are conveyed to the RGV100 through the conveyor chain 2 3021 and the conveyor chain 1032 to complete the receiving of the goods. Then the RGV100 moves the goods to the designated position. Repeating the above operation can complete the transportation and conveying of the goods. This chain-type RGV, with its conveying direction and running direction in the same direction, features an advanced design, compact structure, ease of use, and reliable operation. By setting a chain mounting frame 1034 with a small spacing on the RGV100 and a chain mounting frame 302 with a larger spacing on the chain conveyor 300, the chain mounting frames 1034 and 302 are staggered, ensuring that the chains at both ends do not collide when the RGV100 interacts with the chain conveyor 300. This avoids mechanical damage caused by positioning errors and improves the fault tolerance and operational stability of the RGV100.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
