Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional garages, and specifically to a vehicle conveying device for a three-dimensional garage. Background Technique

[0002] A chain plate conveyor is a conveying device with a standard chain plate as the bearing surface and powered by a motor reducer. The chain plate conveyor consists of a power device (motor), a drive shaft, a roller, a tensioning device, a sprocket, a chain, a bearing, a lubricant, a chain plate, and so on. During the process of transporting vehicles, an intelligent handling trolley transports the vehicle onto the chain plate conveyor, and then the vehicle is transported to the lift by the chain plate conveyor.

[0003] For example, a three-dimensional garage chain plate conveyor with the publication number CN216784654U supports the track at the upper half position of the chain plate through a support rod. After the plate moves to the upper half, the track wheel slides on the track and supports the plate, avoiding the problem that the plate is deformed and damaged due to the heavy weight of the vehicle and the small supporting force at the middle position of the plate, which affects the normal use of the garage. However, during actual use, when the vehicle is being transported, the vehicle wheels only contact two or three individual chain plates. During the transportation process, the movement of multiple chain plates drives the track wheels to rotate on the track, and only individual chain plates actually bear the weight. As the chain plates move and multiple track wheels rotate, it will increase the burden of the chain plate movement. Moreover, when the chain plates move, the track wheels that do not support the weight will also rotate. Multiple track wheels are always in a moving state, with limited service life and inconvenient for later maintenance work, and there are certain usage defects.

[0004] Therefore, we propose a vehicle conveying device for a three-dimensional garage to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of the present invention is to provide a vehicle conveying device for a three-dimensional garage to solve the problems in the above background technique that when the vehicle is being transported, the vehicle wheels only contact two or three individual chain plates. During the transportation process, the movement of multiple chain plates drives the track wheels to rotate on the track, and only individual chain plates actually bear the weight. As the chain plates move and multiple track wheels rotate, it will increase the burden of the chain plate movement. Moreover, when the chain plates move, the track wheels that do not support the weight will also rotate. Multiple track wheels are always in a moving state, with limited service life and inconvenient for later maintenance work.

[0025] By adopting the above technical solution, the lubricating oil can be sprayed onto the top of the guide rail for auxiliary lubrication.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: for the vehicle conveying device of the three-dimensional garage, a support assembly is arranged between the two mounting frames, so that when conveying the vehicle, only the load-bearing chain plate can be supported, the stability of the chain plate is improved, the contact between the remaining multiple rollers and the guide rail is avoided, excessive friction is avoided, the resistance brought is reduced, and the multiple rollers and the support wheels are not always in the working state, the service life is prolonged, and the later maintenance is convenient;

[0027] 1. A support component is arranged between two mounting brackets. When transporting a vehicle, the vehicle is placed between the mounting brackets, and the pressure on the wheels can act on the chain plates. The middle part of the chain plates can produce slight deformation under the pressure, which enables the rollers at the bottom of a certain chain plate to descend. During the descent of the rollers, the first ball bearings first come into contact with the fixed plate. As the rollers continue to descend, the first ball bearings rotate on the fixed plate and can drive the mounting rod to rotate, causing the rotating shaft to rotate between the mounting blocks. After the rotating shaft rotates, it can drive the push rod to rotate. Since the length of the push rod is much greater than that of the mounting rod, the rotation range of the push rod is much greater than that of the mounting rod. After the push rod rotates, it can push the movable plate to move, so that after the mounting rod rotates, it can push the movable plate to move, causing the rollers to come into contact with the guide rails, and the movable plate moves upward. Under the action of the push rod, the displacement of the movable plate is consistent with the displacement of the rollers. After the movable plate moves upward, it slides on the positioning rod and stretches the telescopic spring. After the movable plate moves upward, it can pull one side connecting rod to rotate. After one side connecting rod rotates, it drives the cross bar to rotate. After the cross bar rotates, it can push the other side connecting rod to rotate, so that the other side connecting rod can push the movable sleeve to slide on the fixed rod through the connecting plate, making the two support wheels come into contact with the guide rails on both sides. Thus, when transporting the vehicle, only the load-bearing chain plates are supported, and the rollers on the other chain plates and the support wheels are in a suspended state. When placing the vehicle, multiple chain plates randomly bear the load. Through the support component, when transporting the vehicle, only the load-bearing chain plates can be supported, improving the stability of the chain plates, avoiding the contact of the other multiple rollers with the guide rails, avoiding excessive friction, reducing the resistance, and the multiple rollers and support wheels are not always in the working state, improving the service life and facilitating the later maintenance;

[0028] 2. When transporting the vehicle, the load-bearing support wheels can drive the connecting frame to move downward. After the connecting frame moves downward, it can drive the push block on the positioning frame to move downward. After the positioning frame moves downward, the drive motor drives the chain plates to move through the chain. When the load-bearing chain plates move to the middle of the mounting brackets, the push block can come into contact with the arc-shaped block on the cylinder body, while the push blocks under the non-load-bearing chain plates do not come into contact with the arc-shaped block. After the push block comes into contact with the arc-shaped block, it can push the arc-shaped block to move downward, driving the sliding rod to slide on the cylinder body and compress the return spring, and then driving the piston to move downward. During the downward movement of the piston, the one-way valve inside the air inlet closes, and the one-way valve inside the air inlet pipe opens, enabling the air inside the cylinder body to be pushed into the air inlet pipe. After the push block separates from the arc-shaped block, under the action of the return spring, the sliding rod and the piston reset and move upward. At this time, the one-way valve inside the air inlet opens, and the one-way valve inside the air inlet pipe closes, enabling the outside air to be pumped into the cylinder body. Thus, as the load-bearing chain plates move, the air inlet pipe can be continuously inflated, enabling the fuel tank to be pressurized;

[0029] 3. After the load-bearing chain plate moves, it can pressurize the oil storage tank. After the oil storage tank is pressurized, the lubricating oil inside can be pushed into the installation pipe by the pressure. The height of the air inlet pipe on the oil storage tank is slightly higher than the height of the lubricating oil liquid level, and the lubricating oil liquid level is flush with the top of the oil outlet pipe. After the oil storage tank is pressurized, the lubricating oil can be pushed into the installation pipe, and then the lubricating oil is sprayed onto the top of the guide rail through the oil outlet pipe. After that, a certain amount of lubricating oil can adhere to the surfaces of the support wheels and rollers when they rotate on the guide rail, enabling lubrication work, reducing friction, extending the service life of the rollers and support wheels, and improving the practicality.

[0042] It further includes:

[0043] A support assembly 2, which is arranged between the two groups of mounting frames 1, and the support assembly 2 includes a fixed plate 201;

[0044] The fixed plate 201 is arranged below a plurality of upper chain plates 101, and a plurality of fixed plates 201 are provided. Support rods 202 are symmetrically installed on both sides of the fixed plate 201, and the ends of the two support rods 202 far from the fixed plate 201 are fixedly connected to the mounting frame 1. At the same time, three guide rails 203 are fixedly installed on the top of a plurality of fixed plates 201. At the same time, limit blocks 204 are symmetrically installed on one side of the middle guide rail 203 of a plurality of chain plates 101, and a roller 205 is rotatably connected below between the two limit blocks 204;

[0045] The mounting blocks 206 are symmetrically mounted on the sides of the two limiting blocks 204 away from each other. A rotating shaft 207 is rotatably connected between the two mounting blocks 206. A mounting rod 208 is fixedly mounted in the middle of the outer side of the rotating shaft 207. One end of the mounting rod 208 away from the rotating shaft 207 is hinged with a first ball 209. At the same time, push rods 210 are symmetrically mounted on both sides of the outside of the rotating shaft 207. One end of each of the two push rods 210 away from the rotating shaft 207 is hinged with a second ball 211;

[0046] The movable plates 212 are symmetrically arranged on one side above the two groups of push rods 210. Positioning rods 213 are symmetrically and slidably connected to one side inside the movable plates 212. Compression springs 214 are sleeved on the lower parts of the two positioning rods 213. One end of each compression spring 214 is fixedly connected to the movable plate 212. At the same time, the other end of each compression spring 214 is fixedly mounted with a fixing block 215. The fixing block 215 is fixedly connected to the positioning rod 213. The positioning rod 213 is fixedly connected to the chain plate 101;

[0047] A plurality of chain plates 101 are symmetrically mounted with fixing rods 216 on one side of the two movable plates 212. Movable sleeves 217 are slidably connected to the outside of the two fixing rods 216. A connecting plate 218 is fixedly mounted on one side of one movable sleeve 217. Fixing frames 219 are symmetrically mounted on both sides of the movable plates 212 at the bottom of the chain plate 101. A rotating rod 220 is rotatably connected between the two fixing frames 219. A cross bar 221 is fixedly mounted on the outside of the rotating rod 220. Support blocks 2171 are fixedly mounted on the sides of the two movable sleeves 217 close to each other. A support wheel 2172 is rotatably connected between the two support blocks 2171. At the same time, the two support wheels 2172 are respectively rotatably connected to the left and right guide rails 203;

[0048] Connecting rods 222 are symmetrically hinged to one side of the cross bar 221. One ends of the two connecting rods 222 away from the cross bar 221 are respectively hinged to the connecting plate 218 and the movable plate 212.

[0049] Example 1: As Figures 1 - 7As shown in the figure, a support assembly 2 is arranged between two mounting brackets 1. When transporting a vehicle, the vehicle is placed between the mounting brackets 1, and the pressure on the wheels can act on the chain plate 101. The middle part of the chain plate 101 can produce slight deformation under the pressure, so that the roller 205 at the bottom of a certain chain plate 101 can be driven to descend. During the descent of the roller 205, the first ball 209 first contacts the fixed plate 201. As the roller 205 continues to descend, the first ball 209 rotates on the fixed plate 201 and can drive the mounting rod 208 to rotate, so that the rotating shaft 207 rotates between the mounting blocks 206. After the rotating shaft 207 rotates, it can drive the push rod 210 to rotate. Since the length of the push rod 210 is much greater than the length of the mounting rod 208, the rotation range of the push rod 210 is much greater than the rotation range of the mounting rod 208. After the push rod 210 rotates, it can push the movable plate 212 to move, so that after the mounting rod 208 rotates, it can push the movable plate 212 to move, so that the roller 205 contacts the guide rail 203, and the movable plate 212 moves upward. Under the action of the push rod 210, the displacement of the movable plate 212 is consistent with the displacement of the roller 205. After the movable plate 212 moves upward, it slides on the positioning rod 213 and stretches the telescopic spring 214. After the movable plate 212 moves upward, it can pull one side connecting rod 222 to rotate. After one side connecting rod 222 rotates, it drives the cross bar 221 to rotate. After the cross bar 221 rotates, it can push the other side connecting rod 222 to rotate, so that the other side connecting rod 222 can push the movable sleeve 217 to slide on the fixed rod 216 through the connecting plate 218, so that the two support wheels 2172 contact the guide rails 203 on both sides. Therefore, when transporting the vehicle, only the load-bearing chain plate 101 will be supported, and the rollers 205 on the remaining chain plates 101 and the support wheels 2172 are in a suspended state. When placing the vehicle, multiple chain plates 101 randomly bear the load. Through the support assembly 2, when transporting the vehicle, only the load-bearing chain plate 101 can be supported, improving the stability of the chain plate 101, preventing the remaining multiple rollers 205 from contacting the guide rail 203, avoiding excessive friction and reducing the resistance. Moreover, the multiple rollers 205 and the support wheels 2172 are not always in a working state, improving the service life and facilitating later maintenance.

[0050] In the middle of the inner side of one side mounting bracket 1, a cylinder body 223 is fixedly installed, and a connecting frame 224 is fixedly installed on one side close to the movable sleeve 217 of the cylinder body 223. And on one side inside the connecting frame 224, a guide rod 225 is slidably connected. At the same time, the guide rod 225 is fixedly connected with the chain plate 101;

[0051] On one side of the top of the connecting frame 224, a positioning frame 226 is fixedly installed, and on one side of the bottom of the positioning frame 226, a pushing block 227 is fixedly installed. Inside the cylinder body 223, a piston 231 is slidably connected. At the top of the piston 231, a sliding rod 228 is fixedly installed. At the top end of the sliding rod 228, an arc-shaped block 230 is fixedly installed. The pushing block 227 is slidably connected to the arc-shaped block 230;

[0052] Above the outer part of the sliding rod 228, a return spring 229 is sleeved. The two ends of the return spring 229 are respectively fixedly connected to the arc-shaped block 230 and the cylinder body 223;

[0053] In the middle of the outer side of one mounting frame 1, a fuel storage tank 234 is fixedly installed. The top of the fuel storage tank 234 is connected through a fuel filling port, and a sealing cover is threadedly connected to the outside of the fuel filling port. Below one side of the cylinder body 223, an air inlet pipe 233 is connected through. The air inlet pipe 233 passes through one mounting frame 1 and is connected through the fuel storage tank 234. Below the other side of the cylinder body 223, an air inlet 232 is opened through. Check valves are arranged inside both the air inlet pipe 233 and the air inlet 232.

[0054] Embodiment 2: As Figures 2 - 3 and Figures 8 - 9 shown, when transporting a vehicle, the supporting wheel 2172 under load can drive the connecting frame 224 to move downward. After the connecting frame 224 moves downward, it can drive the pushing block 227 on the positioning frame 226 to move downward. After the positioning frame 226 moves downward, the drive motor drives the chain plate 101 to move through the chain. When the chain plate 101 under load moves to the middle of the mounting frame 1, the pushing block 227 can contact the arc-shaped block 230 on the cylinder body 223, while the pushing block 227 under the unloaded chain plate 101 will not contact the arc-shaped block 230. After the pushing block 227 contacts the arc-shaped block 230, it can push the arc-shaped block 230 downward, driving the sliding rod 228 to slide on the cylinder body 223 and compress the return spring 229, thereby driving the piston 231 to move downward. During the downward movement of the piston 231, the check valve inside the air inlet 232 closes, and the check valve inside the air inlet pipe 233 opens, allowing the air inside the cylinder body 223 to be pushed into the air inlet pipe 233. After the pushing block 227 separates from the arc-shaped block 230, under the action of the return spring 229, the sliding rod 228 and the piston 231 reset and move upward. At this time, the check valve inside the air inlet 232 opens, and the check valve inside the air inlet pipe 233 closes, allowing the outside air to be drawn into the cylinder body 223. Then, as the loaded chain plate 101 moves, the air inlet pipe 233 can be continuously inflated, enabling the fuel storage tank 234 to be pressurized.

[0055] One side of the bottom of the fuel tank 234 is connected through an installation pipe 235, and the installation pipe 235 is fixedly connected to one side of the installation frame 1. On one side of the middle fixing plate 201, positioning blocks 236 are symmetrically installed, and the installation pipe 235 is fixedly connected to the two positioning blocks 236. At the top of the installation pipe 235, oil outlet pipes 237 are connected through all under several guide rails 203, and the oil outlet pipes 237 are connected through the guide rails 203.

[0056] Embodiment 3: As Figures 2 - 3 and Figure 9 shown, after the load-bearing chain plate 101 moves, it can pressurize the fuel tank 234. After the fuel tank 234 is pressurized, the lubricating oil inside can be pushed into the installation pipe 235 by the pressure. The height of the air inlet pipe 233 on the fuel tank 234 is slightly higher than the lubricating oil liquid level height, and the lubricating oil liquid level is flush with the top of the oil outlet pipe 237. After the fuel tank 234 is pressurized, the lubricating oil can be pushed into the installation pipe 235, and then the lubricating oil is sprayed onto the top of the guide rail 203 through the oil outlet pipe 237. After that, a certain amount of lubricating oil can adhere to the surfaces of the support wheels 2172 and the rollers 205 when they rotate on the guide rail 203, so that lubrication work can be carried out, friction can be reduced, the service life of the rollers 205 and the support wheels 2172 can be extended, and the practicability is improved.

[0057] Working principle: When using the vehicle conveying device for the three-dimensional garage, first, according to Figures 1 - 9As shown, a support assembly 2 is provided between two mounting brackets 1. When transporting a vehicle, the vehicle is placed between the mounting brackets 1, and the pressure on the wheels can act on the chain plate 101. A slight deformation can occur in the middle of the chain plate 101 under the pressure, causing the roller 205 at the bottom of a certain chain plate 101 to descend. During the descent of the roller 205, the first ball 209 first contacts the fixed plate 201. As the roller 205 continues to descend, the first ball 209 rotates on the fixed plate 201 and can drive the mounting rod 208 to rotate, causing the rotating shaft 207 to rotate between the mounting blocks 206. After the rotating shaft 207 rotates, it can drive the push rod 210 to rotate. Since the length of the push rod 210 is much greater than the length of the mounting rod 208, the rotation range of the push rod 210 is much greater than the rotation range of the mounting rod 208. After the push rod 210 rotates, it can push the movable plate 212 to move, so that after the mounting rod 208 rotates, it can push the movable plate 212 to move, causing the roller 205 to contact the guide rail 203, and the movable plate 212 moves upward. Under the action of the push rod 210, the displacement of the movable plate 212 is consistent with the displacement of the roller 205. After the movable plate 212 moves upward, it slides on the positioning rod 213 and stretches the telescopic spring 214. After the movable plate 212 moves upward, it can pull one side connecting rod 222 to rotate. After one side connecting rod 222 rotates, it drives the cross bar 221 to rotate. After the cross bar 221 rotates, it can push the other side connecting rod 222 to rotate, so that the other side connecting rod 222 can push the movable sleeve 217 to slide on the fixed rod 216 through the connecting plate 218, causing the two support wheels 2172 to contact the guide rails 203 on both sides. Thus, when transporting the vehicle, only the load-bearing chain plates 101 are supported, and the rollers 205 on the remaining chain plates 101 and the support wheels 2172 are in a suspended state, and when placing the vehicle, multiple chain plates 101 bear the load randomly;

[0058] When transporting the vehicle, the supporting wheel 2172 under load can drive the connecting frame 224 to move downward. After the connecting frame 224 moves downward, it can drive the push block 227 on the positioning frame 226 to move downward. After the positioning frame 226 moves downward, the driving motor drives the chain plate 101 to move through the chain. When the load-bearing chain plate 101 moves to the middle of the mounting frame 1, the push block 227 can contact the arc-shaped block 230 on the cylinder body 223, while the push block 227 under the non-load-bearing chain plate 101 will not contact the arc-shaped block 230. After the push block 227 contacts the arc-shaped block 230, it can push the arc-shaped block 230 to move downward, driving the sliding rod 228 to slide on the cylinder body 223 and compress the return spring 229, thereby driving the piston 231 to move downward. During the downward movement of the piston 231, the check valve inside the air inlet 232 closes, and the check valve inside the air inlet pipe 233 opens, allowing the air inside the cylinder body 223 to be pushed into the air inlet pipe 233. After the push block 227 separates from the arc-shaped block 230, under the action of the return spring 229, the sliding rod 228 and the piston 231 reset and move upward. At this time, the check valve inside the air inlet 232 opens, and the check valve inside the air inlet pipe 233 closes, allowing the outside air to be pumped into the cylinder body 223. Then, as the load-bearing chain plate 101 moves, the air inlet pipe 233 can be continuously inflated, enabling the pressure of the fuel storage tank 234 to be increased. After the load-bearing chain plate 101 moves, the fuel storage tank 234 can be pressurized. After the fuel storage tank 234 is pressurized, the lubricating oil inside can be pushed into the installation pipe 235 by the pressure. The height of the air inlet pipe 233 on the fuel storage tank 234 is slightly higher than the lubricating oil liquid level, and the lubricating oil liquid level is flush with the top of the oil outlet pipe 237. After the fuel storage tank 234 is pressurized, the lubricating oil can be pushed into the installation pipe 235, and then the lubricating oil is sprayed onto the top of the guide rail 203 through the oil outlet pipe 237. Then, after the supporting wheel 2172 and the roller 205 rotate on the guide rail 203, a certain amount of lubricating oil can adhere to their surfaces, enabling lubrication work, reducing friction, and extending the service life of the roller 205 and the supporting wheel 2172.
