DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Embodiment 1:

[0054] See also Figure 1-14 A switch cabinet trolley transfer device is used to transfer a trolley 2 in a switch cabinet 1. The trolley 2 is provided with a handle 3 and rollers, including:

[0055] A transfer vehicle body 5 is provided with a lifting mechanism 6, a support plate 7 is provided above the lifting mechanism 6, and a through opening 4 is opened on the support plate 7; two guide rail support plates 8 are provided and are symmetrically arranged on the support plate 7; an adjustment mechanism 9 is provided on the support plate 7, and is used to make the two guide rail support plates 8 approach or move away from each other; two connecting clamping plates 10 are provided and are slidably arranged on the two guide rail support plates 8 respectively, and a clamping assembly 11 for connecting with the handle 3 is provided on the connecting clamping plate 10; a transmission mechanism 12 is provided on the support plate 7, and is used to drive the two connecting clamping plates 10 to move back and forth along the guide rail support plates 8.

[0056] During use, when the trolley 2 in the switch cabinet 1 needs to be moved out for inspection and maintenance, the transfer vehicle body 5 of the present application can be moved to the corresponding position of the switch cabinet 1, and the cabinet door at the trolley 2 on the switch cabinet 1 is opened, and then the lifting mechanism 6 is operated to rise. At this time, the lifting mechanism 6 will drive the support plate 7 to rise, so that the guide rail support plate 8 on the support plate 7 is flush with the track in the cabinet body of the trolley 2 of the switch cabinet 1. Then, the transmission mechanism 12 drives the two connecting cards 10 to move along the guide rail support plate 8 toward the trolley 2. After finally moving to the specified position, the card assembly 11 on the connecting card plate 10 will be carded together with the handle 3. Then, the transmission mechanism 12 drives the two connecting card plates 10 to move in the direction away from the switch cabinet 1. At this time, the card assembly 11 of the connecting card plate 10 will drive the trolley 2 to move together, gradually pulling the trolley 2 onto the guide rail support plate 8 of the support plate 7, and the rollers at the bottom of the trolley 2 will slide along the guide rail support plate 8. Finally, the trolley 2 is separated from the switch cabinet 1 and moved onto the support plate 7. At this time, the removal of the trolley 2 is completed, and then the lifting mechanism 6 is operated to lower and drive the trolley 2 to a lower position, and then the transfer car body 5 is moved to drive the trolley 2 to move to the maintenance area for operation; and when the subsequent trolley 2 is overhauled and maintained, the transfer car body 5 drives the trolley 2 is moved to the position of the switch cabinet 1 again, and the lifting mechanism 6 is operated to drive the trolley 2 to rise to the corresponding position, so that the guide support plate 8 on the support plate 7 is flush with the track in the cabinet body of the switch cabinet 1, and then the two connecting clamps 10 are driven by the transmission mechanism 12 to move toward the direction of the switch cabinet 1, that is, the clamping assembly 11 will push the trolley 2 to move it to the inside of the switch cabinet 1, that is, the moving in of the trolley 2 is completed. The operation is simple and convenient, avoiding the current method of manually pulling and pushing the trolley 2 to make it enter and exit, saving a lot of labor and time, significantly improving the working efficiency, and facilitating the elderly and inoperable workers. It can also greatly avoid the situation that may cause workers to be injured during the pulling out and pushing in process, saving operation time, and effectively protecting the personal safety of operators, improving the quality of equipment maintenance, and having broad application prospects.

[0057] Before each use, the adjustment mechanism 9 can be operated according to the different types of trolleys 2. The adjustment mechanism 9 will drive the two guide rail support plates 8 to move closer or farther away from each other, that is, it can change the distance between the two guide rail support plates 8, so that the positions of the two guide rail support plates 8 can be adjusted according to the width of different trolleys 2. It has a wide range of applications and can meet the needs of various types of trolleys 2, avoiding the current need to use transfer vehicles of different models. It not only greatly reduces the procurement cost, but also avoids the situation where multiple transfer vehicles occupy more working space, ensuring that there is enough working space on site in the switch room, with strong flexibility and practicality.

[0058] The opening 4 provided on the support plate 7 can facilitate the inspection and maintenance operations on the bottom of the handcart 2, and effectively prevent the situation where the handcart 2 needs to be lifted sometimes, and the use effect is good.

[0059] In this embodiment, preferably, please refer to Figure 4-6 and Figure 9-11 , the adjustment mechanism 9 comprises:

[0060] The connecting frame 91 is arranged on the supporting plate 7, and a transmission seat 92 is arranged on the connecting frame 91. A first rotating shaft 93 is rotatably arranged on the transmission seat 92, and a first spur gear 94 is arranged on the first rotating shaft 93; two first tooth plates 95 are provided and are respectively connected to the guide rail support plates 8 on both sides, and the two first tooth plates 95 are meshed with the first spur gear 94; a driving assembly 96 is arranged in the transmission seat 92, and is used to drive the first rotating shaft 93 to rotate. Operating the driving assembly 96 will drive the first rotating shaft 93 to rotate, and the first rotating shaft 93 will drive the first spur gear 94 to rotate, and the first spur gear 94 will drive the first tooth plates 95 on both sides to move, and the first tooth plates 95 on both sides move in opposite directions, and the first tooth plates 95 will drive the guide rail support plates 8 to move, that is, the guide rail support plates 8 on both sides will move in the direction of approaching or moving away from each other.

[0061] In this embodiment, preferably, please refer to Figure 4-6 and Figure 9-11 A transmission cavity 14 is defined in the transmission seat 92 , and the driving assembly 96 comprises: a second rotating shaft 961 rotatably disposed on the transmission seat 92 , one side of the second rotating shaft 961 extends into the transmission cavity 14 and is provided with a worm 962 ; a worm wheel 963 meshing with the worm 962 is disposed on the first rotating shaft 93 .

[0062] By rotating the second rotating shaft 961, the worm 962 will be driven to rotate, and the worm 962 will drive the worm wheel 963 and the first rotating shaft 93 to rotate, thereby driving the first spur gear 94 to rotate and the first tooth plate 95 to move. Due to the self-locking property of the worm 962 and the worm wheel 963, the worm 962 can only drive the worm wheel 963 to rotate by rotating the second rotating shaft 961, but not vice versa. Therefore, the stability of the adjusted first tooth plate 95 and the guide rail support plate 8 can be better guaranteed, thereby improving the subsequent movement and support stability of the opponent car 2.

[0063] The support plate 7 is also provided with a matching plate 29, and a turntable 13 is provided at the outer end of the second rotating shaft 961. The turntable 13 is provided with a plurality of limiting holes 28. The matching plate 29 is provided with a plug hole matching the limiting hole 28, and a plug rod 25 matching the plug hole is movably provided on the limiting hole 28. The second rotating shaft 961 can be driven to rotate more by rotating the turntable 13. When it is rotated to the corresponding position, the plug rod 25 can be inserted into the limiting hole 28 and also inserted into the plug hole of the matching plate 29, so that the turntable 13 can be restricted, and the phenomenon of the turntable 13 rotating due to accidental touch and vibration can be prevented, so as to better protect the stability of the subsequent guide rail support plate 8.

[0064] In this embodiment, preferably, please refer to Figure 4-5 and Fig. 9 The support plate 7 is provided with a slide rail 15, and a slider 16 connected to the guide rail support plate 8 is slidably provided on the slide rail 15. The support plate 7 is also provided with a slide groove 17, and the first tooth plate 95 is slidably connected with the slide groove 17. When the adjustment mechanism 9 drives the guide rail support plate 8 to move, the guide rail support plate 8 will drive the slider 16 to move along the slide rail 15, thereby improving the stability and smoothness of the movement of the guide rail support plate 8, and the use effect is good. When the first tooth plate 95 moves, it will slide along the slide groove 17, which can improve the movement stability of the first tooth plate 95.

[0065] In this embodiment, preferably, please refer to Figure 4 and Figure 7-9 , the positioning assembly 11 includes:

[0066] The clamping rod 111 is provided on the connecting clamping plate 10, and an inner displacement groove 112 is provided in the clamping rod 111, and a clamping block 113 is slidably connected in the inner displacement groove 112, and a first elastic member 114 is provided between the clamping block 113 and the inner displacement groove 112; a limit push block 115 is provided between the connecting clamping plate 10 and the clamping block 113; and a release member 116 is provided in the connecting clamping plate 10, and is used to move the clamping block 113 toward the inner displacement groove 112. The first elastic member 114 in the present application can be a spring or other elastic structure.

[0067] When the transmission mechanism 12 drives the two connecting clamps 10 to move toward the trolley 2, the clamping rod 111 and the clamping block 113 move with the connecting clamp 10. When the clamping block 113 begins to contact the handle 3 of the trolley 2, the clamping block 113 will be compressed and move toward the inner displacement groove 112 and compress the first elastic member 114. When the clamping block 113 continues to move beyond the handle 3 with the clamping rod 111, the clamping block 113 is no longer compressed. The rebound force of the first elastic member 114 will drive the clamping block 113 to move out of the inner displacement groove 112 and return to the initial position. At this time, the handle 3 is clamped between the clamping block 113 and the limit push block 115. Thereafter, when the transmission mechanism 12 drives the connecting clamp 10 to move away from the switch cabinet 1, the connecting clamp 10 will drive the clamping rod 111 and the clamping block 113 to move. At this time, the trolley 2 will also be driven to move together by pulling the handle 3. Similarly, when the trolley 2 is subsequently pushed into the switch cabinet 1, the limit push block 115 on the connecting clamp 10 will also push the trolley 2 to move into the switch cabinet 1, so that the trolley 2 can be easily moved out and in, and the use effect is good. After the trolley 2 is moved into the switch cabinet 1, the clamp block 113 can be driven to move into the inner displacement groove 112 by the release component 116. At this time, the handle 3 is no longer clamped, and the connecting clamp 10 and the clamping rod 111 can be moved, and the handle 3 will be separated from the clamping rod 111.

[0068] In this embodiment, preferably, please refer to Figure 7-9 An inner cavity 18 is opened in the connecting clamping plate 10, and the releasing component 116 includes a first rotating rod 1161 and a second rotating rod 1162 rotatably arranged in the inner cavity 18, the first rotating rod 1161 is provided with a first bevel gear 1163 and a first rope drum 1164, the first rope drum 1164 is wound with a first traction rope 1165, the other end of the first traction rope 1165 is connected to the positioning block 113, and the second rotating rod 1162 is provided with a second bevel gear 1166 meshing with the first bevel gear 1163. When the second rotating rod 1162 is rotated, the second bevel gear 1166 will be driven to rotate, and the second bevel gear 1166 will drive the first bevel gear 1163 and the first rotating rod 1161 to rotate. At this time, the first rope drum 1164 on the first rotating rod 1161 will rotate, and the first rope drum 1164 will wind and tighten the first traction rope 1165, and the first traction rope 1165 will pull the first bevel gear 1163 to move toward the inner displacement groove 112.

[0069] In this embodiment, preferably, please refer to Figure 4-5 and Figure 9-11 The internal movable insert of the connecting card plate 10 is provided with a work frame 19, and the transmission mechanism 12 includes:

[0070] The transmission shaft 121 is rotatably arranged on the inner wall of the through hole 4, and a driving member 122 is provided on the support plate 7 and is connected to the transmission shaft 121; a plurality of barrel groups are provided on the transmission shaft 121, and each barrel group includes two second rope drums 123, and the second traction rope 124 and the third traction rope 125 are respectively wound and connected on the two second rope drums 123, and the other ends of the second traction rope 124 and the third traction rope 125 are respectively connected to the two sides of the work frame 19. The driving member 122 in the present application can be a servo motor.

[0071] The driving member 122 will drive the transmission shaft 121 to rotate, and the transmission shaft 121 will drive multiple drum groups to rotate, that is, drive the second rope drum 123 to rotate. When the connecting pallet 10 is moved toward the direction of the switch cabinet 1, the third traction rope 125 will be wound and recovered, and the second traction rope 124 will be released outward and stretched along with the movement of the I-shaped frame 19 of the connecting pallet 10. Similarly, when the connecting pallet 10 moves away from the switch cabinet 1, the second traction rope 124 will be wound and recovered, and the third traction rope 125 will be released outward, which can realize the reciprocating movement of the I-shaped frame 19, that is, the reciprocating movement of the connecting pallet 10 along the guide rail support plate 8.

[0072] The support plate 7 and the transmission seat 92 are both provided with a rotatable steering wheel 27, which can realize the conversion of the direction of the second traction rope 124 and the third traction rope 125, so that the second traction rope 124 and the third traction rope 125 can better apply force to the I-shaped frame 19, making the I-shaped frame 19 move more smoothly and reducing the friction of the second traction rope 124 and the third traction rope 125.

[0073] Embodiment 2:

[0074] See also Figure 2-3 , Figure 9-10 and Figure 12-14 On the basis of the first embodiment, it further includes a support plate 20 arranged on the support plate 7, a retractable baffle 21 is slidably provided on the support plate 20, a plurality of tooth blocks 22 are provided on the baffle 21, and a trigger component 23 for driving the baffle 21 to move downward is provided on the support plate 7.

[0075] When the support plate 7 is moved toward the switch cabinet 1, the baffle plate 21 is driven to move downward along the support plate 20 by the trigger assembly 23. Fig.14When the transfer vehicle body 5 is moved away from the switch cabinet 1, the support plate 7 is also separated from the switch cabinet 1. The trigger assembly 23 is no longer effective, and the baffle plate 21 is retracted upward to the initial state. The baffle plate 21 blocks the rear side of the trolley 2, thereby further limiting the position of the trolley 2 through the baffle plate 21, which can greatly prevent the trolley 2 from moving due to bumps and vibrations during the transfer process, and has good protection for the trolley 2. The displacement of the baffle plate 21 can be achieved without manual operation. The structure is ingenious, practical, and effective.

[0076] In this embodiment, preferably, please refer to Figure 2-3 , Figure 9-10 and Figure 12-14 The trigger assembly 23 includes a fixed plate 231 disposed on the support plate 7, a linkage shaft 232 is rotatably disposed on the fixed plate 231, a second spur gear 233 and a third spur gear 234 are rotatably disposed on the linkage shaft 232, the second spur gear 233 is meshed with the tooth block 22, a trigger rod 235 is movably disposed on the support plate 7, and a second tooth plate 236 meshed with the third spur gear 234 is connected to the trigger rod 235. When the support plate 7 approaches the switch cabinet 1, the trigger rod 235 will be pressed and move toward the inside of the support plate 7, the trigger rod 235 will drive the second tooth plate 236 to move, the second tooth plate 236 will drive the third spur gear 234 and the linkage shaft 232 to rotate, the linkage shaft 232 will drive the second spur gear 233 to rotate, and the second spur gear 233 will drive the baffle 21 to move downward through cooperation with the tooth block 22. When the support plate 7 is removed from the switch cabinet 1 , the baffle 21 will move back up, and finally the trigger rod 235 will move out of the support plate 7 and return to the initial position.

[0077] In this embodiment, preferably, please refer to Figure 3 , Fig.10 and Figure 12-14 , a vertical slot 24 is provided on the support plate 20, a connecting block connected to the baffle plate 21 is slidably connected in the vertical slot 24, and a second elastic member 26 is provided between the connecting block and the inner wall of the vertical slot 24. The second elastic member 26 in the present application can be a spring, and when the baffle plate 21 moves downward, it will drive the connecting block to move downward along the vertical slot 24 and compress the second elastic member 26. When the support plate 7 is removed from the switch cabinet 1, the trigger rod 235 is no longer compressed. At this time, the rebound force of the second elastic member 26 will drive the baffle plate 21 to move back to its original position, and finally the trigger rod 235 will also return to its initial state.
