Description

Technical Field

[0001] This utility model relates to the field of RGV logistics equipment technology, specifically a high-speed RGV logistics equipment with a gear and rack structure. Background Technology

[0002] RGV is an abbreviation for Rail Guided Vehicle, also known as a rail shuttle. RGVs can be used in warehouses with various high-density storage methods. The shuttle aisles can be designed to any length, increasing the overall storage capacity of the warehouse. Furthermore, no forklifts are needed to enter the aisles during operation, enhancing safety. RGVs can be easily connected to other logistics systems automatically, such as inbound / outbound platforms, various buffer stations, conveyors, elevators, and robots, to transport materials according to a plan. In addition, they require no human operation and operate at high speed, significantly reducing the workload of warehouse management personnel and improving labor productivity. The application of shuttles also simplifies the logistics system.

[0003] Publication No. CN 220844194 U discloses an RGV cargo trolley for logistics transfer. A device for fixing the trolley to a track is installed under the trolley body, increasing the stability of the equipment. Because the track-fixing device can fix the position of the trolley, it can effectively avoid instability such as shaking and sliding during use, increasing the stability and safety of the equipment and improving its working efficiency. Since the position of the trolley is fixed, the operation time required for adjustment can be reduced, allowing for faster completion of transportation tasks and improved equipment efficiency and safer operation. The track-fixing device makes the trolley more stable and safer when transporting goods, which can greatly reduce the risks to workers during operation and reduce maintenance costs. Fixing the position of the trolley can reduce damage and wear during use, thereby reducing maintenance and repair costs. However, this patent still has the following problems in practical use:

[0004] Although the RGV cargo trolley used for logistics transfer can transport goods, it cannot increase the speed of goods transportation according to the weight of the goods. In existing technologies, the speed of goods transportation is mostly increased by increasing the speed of the drive motor. However, increasing the speed of the drive motor not only increases the burden on the drive motor, but also causes the drive motor to overheat and be damaged due to long-term high-speed rotation, which is not conducive to the long-term operation of the RGV cargo trolley.

[0005] A high-speed RGV logistics device with a gear and rack structure is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a high-speed RGV logistics equipment with a gear and rack structure, so as to solve the problem mentioned in the background art that although the RGV cargo trolley used for logistics transfer can realize the transportation of goods, it cannot increase the speed of goods transportation according to the weight of the goods being transported. In the prior art, most of them increase the speed of goods transportation by increasing the speed of the drive motor. However, increasing the speed of the drive motor not only increases the burden on the drive motor, but also causes the drive motor to overheat and be damaged due to long-term high-speed rotation, which is not conducive to the long-term operation of the RGV cargo trolley.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-speed RGV logistics equipment with a gear and rack structure, including a speed-up mechanism and a track base plate installed at the bottom of the speed-up mechanism;

[0008] The top of the speed-up mechanism is provided with a clamping mechanism, and clamping arms are fixedly installed around the clamping mechanism.

[0009] Also includes:

[0010] The speed-up mechanism includes a trolley bracket, the top of which is symmetrically provided with clamping grooves, and the bottom of which is provided with lifting grooves. Lifting cylinders are fixedly installed around the inside of the lifting grooves.

[0011] One of the lifting cylinders has an adjustment bracket fixedly installed at the bottom, and an adjustment motor is fixedly installed on one side of the inner side of the adjustment bracket.

[0012] The output end of the regulating motor is fixedly connected to a first bidirectional threaded rod, and the outer side of the first bidirectional threaded rod is symmetrically threaded with an adjusting threaded sleeve.

[0013] Preferably, a speed-boosting bracket is fixedly installed at the bottom of the adjusting threaded sleeve, a speed-boosting motor is fixedly installed on the outer side of the speed-boosting bracket, a speed-boosting rotating shaft is fixedly connected to the output end of the speed-boosting motor, and a plurality of speed-boosting gear sets are fixedly installed on the outer side of the speed-boosting rotating shaft.

[0014] Preferably, the bottom of the speed-up gear set is meshing with a rack, and two racks are fixedly installed on the top of the track base plate. Slide rails are symmetrically installed on both sides of the top of the track base plate.

A second bidirectional threaded rod is symmetrically connected to one side of the first sprocket drive assembly.

[0017] Preferably, the outer sides of the two second bidirectional threaded rods are symmetrically threaded with first clamping threaded sleeves, a clamping bracket is fixedly installed on the top of one side of the first clamping threaded sleeve, a second motor cover is fixedly installed on one side of the clamping bracket, and a second clamping motor is fixedly installed on the inner side of the second motor cover.

[0018] Preferably, the output end of the second clamping motor is fixedly connected to a second sprocket drive assembly, a third bidirectional threaded rod is symmetrically connected to one side of the second sprocket drive assembly, a second clamping threaded sleeve is symmetrically threaded to the outer side of the third bidirectional threaded rod, and the clamping arm is fixedly installed on the outer side of the second clamping threaded sleeve.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-speed RGV logistics equipment with a gear and rack structure uses a lifting cylinder to drive the adjusting bracket to move up and down, and starts the adjusting motor to drive the first bidirectional threaded rod to rotate, so that the adjusting threaded sleeve drives the speed-up bracket to move relatively. By starting the speed-up motor, the speed-up rotating shaft and the speed-up gear set are driven to rotate. Utilizing the meshing connection between the speed-up gear set and the meshing rack, the movement of the trolley bracket can be realized. Utilizing the meshing connection between the gears of different diameters inside the speed-up gear set and the meshing rack, the speed-up effect is achieved. The first clamping motor drives the first clamping threaded sleeve to drive the clamping bracket to move relatively, thereby using the clamping bracket to clamp and fix the left and right sides of the goods. At the same time, the second clamping motor is started to drive the second clamping threaded sleeve to drive the clamping arm to move relatively, thereby clamping and fixing the front and rear sides of the goods, improving the stability of goods transportation. The specific details are as follows:

[0020] 1. By setting up a speed-up mechanism, not only can the lifting cylinder drive the adjusting bracket to move up and down, but the adjusting motor can also drive the first bidirectional threaded rod to rotate, causing the adjusting threaded sleeve to move the speed-up bracket relative to each other. By starting the speed-up motor, the speed-up rotating shaft and the speed-up gear set can be rotated. By utilizing the meshing connection between the speed-up gear set and the meshing rack, the movement of the trolley bracket can be realized. By utilizing the meshing connection between gears of different diameters inside the speed-up gear set and the meshing rack, the speed-up effect can be achieved. High-speed movement of the RGV logistics equipment can be achieved by meshing the large gear with the meshing rack, and low-speed movement of the RGV logistics equipment can be achieved by meshing the small gear with the meshing rack. Different speeds can be switched according to the weight of the goods on the trolley bracket, which is convenient for the transportation of goods. By utilizing the sliding limit block and the sliding roller to slide with the slide rail, the stable movement of the trolley bracket can be realized, thereby improving the stability of the trolley bracket movement.

[0021] 2. By setting up a clamping mechanism, not only can the first clamping motor drive the first sprocket transmission assembly and the second bidirectional threaded rod to rotate, causing the first clamping threaded sleeve to drive the clamping bracket to move relative to each other, thereby using the clamping bracket to clamp and fix the left and right sides of the goods, but also the second clamping motor can be started to drive the second sprocket transmission assembly and the third bidirectional threaded rod to rotate, causing the second clamping threaded sleeve to drive the clamping arm to move relative to each other, thereby clamping and fixing the front and rear sides of the goods, improving the stability of goods transportation.

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.

[0030] Please see Figures 1-6This utility model provides a technical solution: a high-speed RGV logistics equipment with a gear and rack structure, including a speed-up mechanism 1 and a track base plate 114 installed at the bottom of the speed-up mechanism 1. A clamping mechanism 2 is provided on the top of the speed-up mechanism 1, and clamping arms 212 are fixedly installed around the clamping mechanism 2. The speed-up mechanism 1 includes a trolley bracket 101. A clamping groove 102 is symmetrically opened on the top of the trolley bracket 101, and a lifting groove 103 is opened on the bottom of the trolley bracket 101. A lifting cylinder 104 is fixedly installed around the inside of the lifting groove 103. An adjusting bracket 105 is fixedly installed at the bottom of one side of the lifting cylinder 104, and an adjusting bracket 105 is fixedly installed on one side of the inside of the adjusting bracket 105. An adjusting motor 106 is provided, wherein the output end of the adjusting motor 106 is fixedly connected to a first bidirectional threaded rod 107, and the outer side of the first bidirectional threaded rod 107 is symmetrically threaded with an adjusting threaded sleeve 108.

The bottom of the speed-boosting gear sets 112 is meshed with a meshing rack 113, and two meshing racks 113 are fixedly installed on the top of the track base plate 114. The top two sides of the track base plate 114 are symmetrically connected. The trolley bracket 101 is equipped with a slide rail 115, and sliding limit blocks 116 are symmetrically installed around the bottom. Each sliding limit block 116 has a sliding roller 117 rotatably connected to one side of its inner side. The sliding roller 117 is in contact with the slide rail 115. The sliding limit blocks 116 are symmetrically arranged on both sides of the slide rail 115. A lifting cylinder 104 drives the adjusting bracket 105 to move up and down, and the adjusting motor 106 drives the first bidirectional threaded rod 107 to rotate, causing the adjusting threaded sleeve 108 to move the speed-up bracket 109 relative to it.

The connection features enable the movement of the trolley support 101. Utilizing the meshing connection between gears of different diameters within the speed-increasing gear set 112 and the meshing rack 113, a speed-increasing effect is achieved. High-speed movement of the RGV logistics equipment is realized through the meshing connection of the large gear and the meshing rack 113, while low-speed movement is achieved through the meshing connection of the small gear and the meshing rack 113. Different speeds can be switched according to the weight of the goods on the trolley support 101, facilitating the transportation of goods. The sliding connection between the sliding limit block 116 and the sliding roller 117 and the slide rail 115 ensures stable movement of the trolley support 101, thereby improving the stability of the trolley support 101's movement.

A first clamping motor 202 is fixedly installed inside the first motor cover 201. A first sprocket drive assembly 203 is fixedly connected to the output end of the first clamping motor 202. A second bidirectional threaded rod 204 is symmetrically connected to one side of the first sprocket drive assembly 203.

The first clamping motor 202 drives the first sprocket drive assembly 203 and the second bidirectional threaded rod 204 to rotate, causing the first clamping threaded sleeve 205 to drive the clamping bracket 206 to move relative to each other. Thus, the clamping bracket 206 clamps and fixes the left and right sides of the goods. At the same time, the second clamping motor 208 is started to drive the second sprocket drive assembly 209 and the third bidirectional threaded rod 210 to rotate, causing the second clamping threaded sleeve 211 to drive the clamping arm 212 to move relative to each other, thereby clamping and fixing the front and rear sides of the goods and improving the stability of goods transportation.

[0032] Working Principle: Before using this high-speed RGV logistics equipment with a gear and rack structure, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, the goods to be transported are placed on the trolley bracket 101. The first clamping motor 202 drives the first sprocket transmission assembly 203 and the second bidirectional threaded rod 204 to rotate, causing the first clamping threaded sleeve 205 to move relative to the clamping bracket 206. This clamping bracket 206 clamps and fixes the goods on both sides. Simultaneously, the second clamping motor 208 is activated, driving the second sprocket transmission assembly 209 and the third bidirectional threaded rod 210 to rotate, causing the second clamping threaded sleeve 211 to move relative to the clamping arm 212. This clamps and fixes the goods on both the front and rear sides, improving the stability of the transport. Secondly, the lifting cylinder 104 drives the adjusting bracket 105 to move up and down, and the adjusting motor 106 is activated, driving the first bidirectional threaded rod 107 to rotate. This causes the adjusting threaded sleeve 108 to move relative to the speed-up bracket 109. The starting speed-up motor 110 drives the speed-up rotating shaft 111 and the speed-up gear set 112 to rotate. Utilizing the meshing connection between the speed-up gear set 112 and the meshing rack 113, the trolley support 101 can move. The speed-up effect is achieved by utilizing the meshing connection of gears of different diameters inside the speed-up gear set 112 with the meshing rack 113. High-speed movement of the RGV logistics equipment is achieved through the meshing connection of the large gear and the meshing rack 113, while low-speed movement is achieved through the meshing connection of the small gear and the meshing rack 113. Different speeds can be switched according to the weight of the goods on the trolley support 101, facilitating the transportation of goods. The sliding limit block 116 and the sliding roller 117 are slidably connected to the slide rail 115, enabling stable movement of the trolley support 101 and thus improving the stability of the trolley support 101's movement.
