[0029] Reference Figures 1 to 3According to the first aspect of the embodiment of the utility model, the vacuum tank external transfer trolley includes a carrying trolley 100, a track assembly 200, a conveying device and a track docking mechanism 400. The track assembly 200 is arranged on the carrying trolley 100. The track assembly 200 can match the trolley in the vacuum tank. The trolley in the vacuum tank can slide along the track assembly 200. The conveying device is arranged on the carrying trolley 100. The conveying device includes a first walking mechanism 310 and a connecting mechanism 320. The connecting mechanism 320 is arranged on the first walking mechanism 310. The connecting mechanism 320 can be connected to the trolley in the vacuum tank, and the first walking mechanism 310 can drive the connecting assembly to move along the track assembly 200. The track docking mechanism 400 is arranged on the carrying trolley 100 and docked with the track assembly 200. The track docking mechanism 400 can be flipped outward to dock with the track of the trolley in the vacuum tank. The carrying trolley 100 can travel to the transfer point, and the track docking mechanism 400 can be flipped outward to dock with the trolley track in the vacuum tank. The trolley in the vacuum tank can be docked to the track assembly 200 through the track docking mechanism 400, and the conveying device is started. The first traveling mechanism 310 is used to drive the connecting mechanism 320 to move along the direction of the track assembly 200 to the trolley in the vacuum tank, and the connecting mechanism 320 is operated to connect the trolley in the vacuum tank, and then the first traveling mechanism 310 is used to pull the trolley in the vacuum tank into the track assembly 200, and then the track docking mechanism 400 is folded. The carrying trolley 100 can transport the trolley in the vacuum tank to the target location. After arriving at the target location, the above-mentioned mechanism is used to send the trolley in the vacuum tank out. There is no need for manual docking, and the degree of automation is high.

[0030] Specifically, the products processed in the vacuum tank are generally carried by the tank trolley, which needs to be sent out and in by the tank transfer trolley outside the tank. In the prior art, the tank transfer trolley outside the tank is generally pushed manually. The connecting rails between the tank transfer trolley outside the tank and the tank trolley are mostly carried manually, which is heavy. Safety accidents may occur during the transportation process, and the labor cost is high. After the connection of the connecting rails is completed, the transfer and conveying mechanism is used to send the tank trolley into the tank transfer trolley outside the tank. The whole process requires a lot of manpower and the degree of automation is low. Therefore, improvements need to be made. In this embodiment, the product in the vacuum tank is carried by the tank trolley. The tank trolley is generally configured as a load-bearing plate with running wheels, and the tank trolley can slide along the track in the tank. When the product needs to be sent out or in, it needs to be transferred by the transfer trolley outside the vacuum tank, and the carrying trolley 100 can travel to the transfer point. In actual use, when the tank trolley needs to be sent out, the carrying trolley 100 travels until the track assembly 200 is aligned parallel to the track in the tank, and then the track docking mechanism 400 is started, and the track docking mechanism 400 is flipped outward from the retracted state. , and the track docking mechanism 400 can be turned over to dock with the track in the tank, so that the track in the tank is connected to the track assembly 200. At this time, the conveying device is started, and the first walking mechanism 310 can drive the connecting mechanism 320 to move toward the trolley in the tank. The specific driving structure of the first walking mechanism 310 is not specifically limited. The first walking mechanism 310 drives the connecting mechanism 320 to reach the trolley in the tank, and it can be sensed in place by sensors such as photoelectric sensing, so that the connecting mechanism 320 can move accurately into place. After it is in place, the connecting mechanism 320 is connected to the trolley in the tank. The connection form of the tank body is not limited. When the connection is completed, the first walking mechanism 310 drives the connecting mechanism 320 to retreat. At this time, the trolley in the tank can slide along the track assembly 200 to the carrier trolley 100. At this time, the track docking mechanism 400 is retracted, and the trolley in the tank is sent out from the vacuum tank. On the contrary, when the trolley in the tank needs to be sent into the vacuum tank, the carrier trolley 100 needs to be driven to the target delivery location, and then the track docking mechanism 400 is started to dock the track in the tank. After the docking is completed, the connecting mechanism 320 remains connected to the trolley in the tank. The first walking mechanism 310 drives the connecting mechanism 320 into the tank. At this time, the trolley in the tank can be driven to the track inside the tank, so as to send the trolley in the tank into the vacuum tank. It can be understood that when the carrying trolley 100 sends the trolley in the tank out of the vacuum tank, it can dock with the track outside the tank, and then start the conveying device to transport the trolley in the tank to the track outside the tank. The track outside the tank can transport the trolley in the tank to the next process. Through the above mechanism, the transfer of the trolley in the tank can be realized, and combined with the electronic control program, it can run automatically without relying on manpower, and has a high degree of automation.

[0031] Reference Figure 1 and Figure 3In some embodiments of the utility model, the first walking mechanism 310 includes a first slide rail 311, a first driving assembly 312 and a first walking arm 313. The first driving assembly 312 is arranged on the carrying trolley 100, the first slide rail 311 is arranged on the carrying trolley 100, and the first slide rail 311 is arranged in parallel with the track assembly 200. The first walking arm 313 is slidably connected with the first slide rail 311, and the first driving assembly 312 is transmission-connected with the first walking arm 313. The first driving assembly 312 can drive the first walking arm 313 to slide along the length direction of the first slide rail 311, and the connecting mechanism 320 is arranged on the first walking arm 313. Through the above structure, the trolley in the tank can be driven to be sent in or out of the carrying trolley 100, and the overall structural setting is relatively simple, and the manufacturing cost is low.

[0032] Specifically, the track assembly 200 can be configured as two guide rails, which are arranged in parallel and at intervals on the top of the carrying trolley 100, and the first slide rail 311 can be arranged between the two guide rails, and the first slide rail 311 is arranged parallel to the guide rails, the first walking arm 313 is slidably connected to the first slide rail 311, and the specific sliding structure is not limited. The first drive assembly 312 can drive the first walking arm 313 to reciprocate in a straight line, and the specific driving structure is not limited. The first drive assembly 312 can be controlled by an electronic control program to achieve automatic operation. The connecting mechanism 320 can be arranged at the end of the first walking arm 313, and the connecting mechanism 320 can also be controlled by an electronic control program. The walking wheels of the trolley in the tank match the guide rails, and the first walking arm 313 in the middle can be connected to the middle part of the trolley in the tank, and the pulling is smoother. Through the above structure, the trolley in the tank can be driven to be sent in or out of the carrying trolley 100, and the structure is simple.

[0033] Reference Figure 1 and Figure 3 In some embodiments of the utility model, the first slide rail 311 has a first slide groove 3111 with an upward opening, the first slide groove 3111 is extended along the length direction of the first slide rail 311, and guide wheels 3131 are provided on both sides of the first walking arm 313, and the guide wheels 3131 abut against the bottom wall of the first slide groove 3111, so that the first walking arm 313 can slide along the first slide groove 3111. This can make the first walking arm 313 run more smoothly.

[0034] Specifically, a plurality of guide wheels 3131 may be provided on both sides of the first walking arm 313, and the number of the guide wheels 3131 is not limited. The guide wheels 3131 abut against the bottom wall of the first slide groove 3111, so that the guide wheels 3131 can roll along the first slide groove 3111, thereby enabling the first walking arm 313 to slide relative to the first slide rail 311, and the sliding resistance is small, so that the first walking arm 313 runs more smoothly.

[0035] It is understandable that a plurality of guide wheels 3131 may be provided, and the load-bearing capacity can be met only by providing a certain number of guide wheels 3131 . The guide wheels 3131 may be provided at intervals along the length direction of the first walking arm 313 .

[0036] Reference Figures 1 to 4 In some embodiments of the utility model, the bottom wall of the first slide groove 3111 is provided with a long first opening 3112, the first opening 3112 is extended along the length direction of the first slide rail 311, and the bottom of the first walking arm 313 is provided with a guide portion 3132, which is inserted into the first opening 3112. The lateral movement of the first walking arm 313 can be limited, so that the movement of the first walking arm 313 is more stable.

[0037] Specifically, the first opening 3112 can be set to be a long strip shape, and the first opening 3112 can extend to the end of the first slide rail 311, the first opening 3112 matches the shape of the guide portion 3132 at the bottom of the first walking arm 313, and the guide portion 3132 is protruded downward so that the guide portion 3132 can be inserted into the first opening 3112, and the side walls of the guide portion 3132 and the side walls of the first opening 3112 restrict each other so that the first walking arm 313 can only slide along a limited direction, thereby making the sliding of the first walking arm 313 more stable and the sliding position more accurate.

[0038] It can be understood that a group of guide wheels 3131 arranged up and down can be respectively provided on both sides of the first walking arm 313, the upper guide wheel 3131 is supported by the bottom wall of the first slide groove 3111, and the lower guide wheel 3131 is supported by the bottom of the first slide rail 311, so that the first walking arm 313 will not separate from the first slide rail 311 upward, making its operation more stable.

[0039] It can be understood that the guide wheel 3131 can be set on a connecting plate, and the connecting plate can be detachably connected to the first walking arm 313. Specifically, it can be connected to the side wall of the first walking arm 313 through fasteners, so that the guide wheel 3131 can be disassembled and replaced for easy maintenance.

[0040] Reference Figures 1 to 4 In some embodiments of the utility model, the first driving assembly 312 includes a first driving motor 3121, a master and slave wheel set 3122 and a transmission chain. The first driving motor 3121 is provided on the carrier trolley 100, the master and slave wheel sets 3122 are transmission-connected to the first driving motor 3121, the transmission chain is provided on the master and slave wheel sets 3122, and the first walking arm 313 is connected to the transmission chain. By adopting the transmission chain transmission, the reliability of the transmission structure can be improved and it is applicable to various working environments.

[0041] Specifically, the master and slave wheel group 3122 can be set to a driving wheel and a driven wheel. The driving wheel and the driven wheel are arranged at intervals along the length direction of the first slide rail 311. The driving wheel is connected to the output shaft of the first drive motor 3121, and a connecting part can be set at the bottom of the first walking arm 313 for connecting to the transmission chain. The first drive motor 3121 can drive the transmission chain to rotate around the master and slave wheel group 3122, thereby driving the first walking arm 313 to move. By adopting a transmission chain drive, the reliability of the transmission structure can be improved and it is suitable for various working environments.

[0042] It should be noted that the first driving assembly 312 is not limited to the above embodiment, and other embodiments may also be adopted. For example, a transmission belt may be adopted to connect the first walking arm 313 to the transmission belt, and transmission is carried out through the transmission belt.

[0043] Reference Figures 1 to 4 In some embodiments of the present invention, the connection mechanism 320 includes a driving member 321 and a pressing block 322. The driving member 321 is disposed on the first walking arm 313, and the pressing block 322 is disposed on the driving member 321. The driving member 321 can drive the pressing block 322 to move up and down. The above structure is relatively simple, which can realize the clamping function and reduce the manufacturing cost.

[0044] Specifically, the driving member 321 can be a cylinder, and the pressure block 322 is arranged on the cylinder output rod, and the cylinder output rod is arranged downward to drive the pressure block 322 to move downward. When the first walking mechanism 310 is in place, the driving member 321 is located above the trolley in the tank, and the pressure block 322 is driven to press the trolley in the tank, and the walking wheels of the trolley in the tank are cooperated to make the trolley in the tank travel onto the carrying trolley 100. It can be understood that the connecting mechanisms 320 can be respectively arranged at both ends of the first walking arm 313, so that the first walking arm 313 can be operated in both directions. The above-mentioned connection structure is simpler than the traditional clamping mechanism, and can achieve the same clamping function, and the manufacturing cost is low.

[0045] It should be noted that the first walking arm 313 may include a long straight arm, with vertically arranged protrusions at both ends of the straight arm respectively, and a driving member 321 may be arranged at the bottom of the protrusion so that the driving member 321 can be located above the trolley in the tank.

[0046] Reference Figures 1 to 3In some embodiments of the present invention, the track docking mechanism 400 includes a driving component 410 and a docking track 420. One end of the docking track 420 is pivotally connected to the carrier 100, and the docking track 420 is arranged corresponding to the track assembly 200. The driving component 410 is arranged on the carrier 100, and the output end of the driving component 410 is connected to the docking track 420. The driving component 410 can drive the docking track 420 to flip. The track docking mechanism 400 can flip and retract, thereby reducing the occupied space of the carrier 100 and facilitating the travel of the carrier 100.

[0047] Specifically, the docking rail 420 can be configured as two parallel and symmetrical guide rails, one end of each guide rail is pivoted to the carrying trolley 100, and the docking rail 420 is configured corresponding to the guide rail of the track assembly 200. The driving component 410 can be configured as a cylinder, the cylinder base end can be pivoted to the carrying trolley 100, and the rod at the other end is pivoted to the middle of the docking rail. The cylinder rod can be extended and retracted to drive the docking rail to flip. When not docked, the docking rail is flipped upward and retracted, which can reduce the occupied space of the carrying trolley 100 and limit the sliding of the trolley in the tank on the carrying trolley 100. When docking is required, it can be flipped outward to realize the docking function and facilitate use.

[0048] It is understandable that a cross bar can be welded between the two guide rails of the track docking mechanism 400. By providing the cross bar, the strength of the docking track 420 can be improved, thereby improving the ability to carry the trolley in the tank, and further enabling the transfer of larger specifications of products.

[0049] Reference Figures 1 to 3 In some embodiments of the present invention, the carrier trolley 100 includes a carrier platform 110 and a driving wheel assembly 120. The driving wheel assembly 120 is disposed at the bottom of the carrier platform 110. The driving wheel assembly 120 can drive the carrier platform 110 to move. The length direction of the track assembly 200 is perpendicular to the travel direction of the driving wheel assembly 120. The inner and outer tracks of the tank can be aligned by driving forward and backward, which is convenient for alignment.

[0050] Specifically, the carrying platform 110 can be welded with channel steel, and the driving wheel assembly 120 can have multiple driving wheels. The driving wheels are at the bottom of the carrying platform 110 to drive the carrying platform 110 to move, and the driving wheel assembly 120 can be driven by a motor, and the motor is output to the driving wheel after transmission with the reducer. The specific transmission method can be a chain drive to realize the electric travel of the carrying trolley 100, so that no human push is required, and the track direction of the track assembly 200 is perpendicular to the travel direction. In actual use, the inner and outer tracks of the tank can be aligned by driving forward and backward, which is convenient for operational alignment.

[0051] It can be understood that the driving wheel assembly 120 can also be configured to be driven by an internal combustion engine, and the specific transmission form can be a shaft transmission or the like.

[0052] Reference Figures 1 to 3 In some embodiments of the utility model, the conveying device further includes a second walking mechanism 330, the first walking mechanism 310 is arranged near one end of the track assembly 200, the second walking mechanism 330 is arranged near the other end of the track assembly 200, the second walking mechanism 330 includes a second slide rail 331, a second driving assembly 332 and a second walking arm 333, the second slide rail 331 is arranged on the carrier trolley 100, and the second slide rail 331 is arranged parallel to the track assembly 200, the second walking arm 333 is slidably connected to the second slide rail 331, the second driving assembly 332 is arranged on the carrier trolley 100, and the second walking arm 333 is transmission-connected to the second driving assembly 332, the second driving assembly 332 can drive the second walking arm 333 to slide along the second slide rail 331, and the second walking arm 333 is provided with a connecting mechanism 320. Both ends of the track assembly 200 have a conveying function, so that different docking situations can be coped with.

[0053] Specifically, the first walking mechanism 310 is arranged at one end of the track assembly 200, and the second walking mechanism 330 is arranged at the other end, so that both sides of the carrying trolley 100 can realize the conveying function. On the one hand, it can improve compatibility, and on the other hand, both sides can simultaneously connect to the tracks inside and outside the tank, thereby realizing simultaneous delivery and entry. The second walking mechanism 330 can be provided with a second slide rail 331, and the second slide rail 331 is arranged parallel to the track assembly 200. The top of the second slide rail 331 has a second slide groove 3311, and the bottom arm of the second slide groove 3311 can be provided with a second opening 3312, and the second opening 3312 is along the length of the second slide rail 331. The second walking arm 333 is extended in the direction, and the second walking arm 333 can be inserted into the second opening 3312 and is slidably connected to the second slide rail 331. The second driving assembly 332 can be connected to the second walking arm 333 through a chain drive, and the second walking arm 333 is provided with a connecting mechanism 320 for connecting to the trolley in the tank. The specific transmission structure of the second walking mechanism 330 is basically the same as the first walking mechanism 310, and is not described in detail herein. Through the above structure, the first walking mechanism 310 can dock with the track inside the tank, and the second walking mechanism 330 can dock with the track outside the tank or dock with the vacuum tank, and can also dock at the same time, which is more convenient to use.

[0054] It should be noted that the second walking mechanism 330 is not limited to the above-mentioned embodiment, and other embodiments may be adopted. For example, the second walking mechanism 330 can be provided with two second slide rails 331 and two second walking arms 333. The track assembly 200 can be provided with two guide rails. The second slide rail 331 can be provided on one side of the corresponding guide rail, and the second driving assembly 332 can be provided with a motor, a transmission shaft and two sets of chain transmission assemblies. The transmission shaft is driven by the motor, and the transmission shaft drives the two sets of chain transmission assemblies at the same time, thereby driving the two second walking arms 333 to slide at the same time, so that the second walking mechanism 330 can enhance the conveying stability, and can avoid the first walking mechanism 310, and the position arrangement is more reasonable.

[0055] Reference Figures 1 to 3 In some embodiments of the present invention, the track docking mechanism 400 is provided in two groups, and the two groups of track docking mechanisms 400 are correspondingly arranged at both ends of the track assembly 200.
