Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The embodiment of the present application discloses a telescopic comb carrier.

[0030] Example

[0031] according to Figures 1 to 4 As shown, a telescopic comb carrier includes a base frame 1, a comb frame 2, two travel motors 4, two centering motors 5, a lifting motor 3 and a PLC system. The travel motor 4, the centering motor 5 and the lifting motor 3 are all servo motors, and the PLC system belongs to the prior art. The PLC system controls the operation of the travel motor 4, the centering motor 5 and the lifting motor 3.

[0032] The left and right ends of the chassis 1 are respectively equipped with a travel motor 4 and a gearbox 17. The output end of the travel motor 4 is connected to the output shaft of the gearbox 17. Sprockets A18 are respectively installed at both ends of the output shaft of the gearbox 17. Two travel wheels 20 are respectively installed at the left and right ends of the chassis 1. Sprockets B19 are installed at the shaft ends of the travel wheels 20. The sprockets B19 correspond to the sprockets A18 one by one. The corresponding sprockets B19 and the sprockets A18 are connected through an annular chain D. The travel motor 4 cooperates with the gearbox 17 to drive the travel wheels 20 to rotate, thereby driving the entire chassis 1 to move. Travel wheels 20 are respectively installed on both sides of the middle of the chassis 1.

[0033] The four corners of the base frame 1 are rotatably connected with guide wheels 21 , respectively, and the guide wheels 21 are used for contacting and guiding the side walls of the parking space.

[0034] The top of the base frame 1 is rotatably connected with three bearings 6, and the outer sides of the three bearings 6 are all sleeved and fixed with guide blocks 7, and the outer sides of the guide blocks 7 are provided with two arc-shaped slope grooves 8 along the circumferential direction. The sparse tooth frame is located at the top of the base frame 1, and the comb tooth frame 2 is installed with three pairs of support rods 10, and the three pairs of support rods 10 correspond to the three bearings 6 one by one. The bearings 6 are located between two support rods 10, and the end of each support rod 10 is rotatably connected with a lifting wheel 9, and the two lifting wheels 9 are respectively located in the two arc-shaped slope grooves 8 of the same guide block 7.

[0035] Four transmission gear sets are installed at the bottom of the base frame 1, and the transmission gear sets include a driving gear A13 and two driven gears A14. The driving gear A13 and the two driven gears A14 are distributed in a triangle. Each driving gear A13 and the driven gear A14 in the four transmission gear sets are meshed and connected through an annular chain A15. One of the transmission gear sets is transmission-connected to the lifting motor 3, and the output end of the lifting motor 3 is coaxially connected to the driving gear A13. The remaining three transmission gear sets correspond to three bearings 6 respectively. The driving gear A13 in each transmission gear set is coaxially connected to the inner ring of the bearing 6. The lifting motor 3 realizes the rotation of the three bearings 6 by driving the rotation of one driving gear A13.

[0036] The bearing 6 rotates to drive the lifting wheel 9 to rotate in the arc-shaped slope groove 8, and the lifting wheel 9 rolls along the inclined surface of the arc-shaped slope groove 8, thereby driving the support rod 10 and the comb tooth frame 2 to lift and lower. When the lifting wheel 9 rolls to the lowest point of the arc-shaped slope groove 8, the comb tooth frame 2 is at the lowest point and the descent is completed. When the lifting wheel 9 rolls to the highest point of the arc-shaped slope groove 8, the comb tooth frame 2 is at the highest point and the lifting and lowering is completed.

[0037] The outer side of the guide block 7 is fixedly connected with a limit plate 11, and the base frame 1 is installed with a micro switch 12. When the guide block 7 drives the lifting wheel 9 to roll to the highest point of the arc-shaped ramp groove 8, the limit plate 11 contacts the micro switch 12, and the micro switch 12 sends a signal to the PLC system, and the PLC system alarms. The PLC system controls the lifting motor to stop running and the bearing 6 to stop rotating.

[0038] Two parallel and spaced proximity switches 16 are installed on one side of the chassis 1. The two proximity switches 16 are aligned with the two ends of the metal sheet installed in the parking space. When the entire chassis 1 moves to the parking space, the two proximity switches 16 are aligned with the two ends of the metal sheet installed in the parking space. The proximity switch 16 sends a signal to the PLC system, and the PLC system controls the travel motor 4 to stop working and the travel wheel 20 to stop rotating, that is, the chassis 1 stops moving, so that the chassis 1 moves accurately to the appropriate position of the parking space. The micro switch 12 and the proximity switch 16 are both prior art, and the signal transmission between the two and the PLC system is also prior art, which will not be described in detail here.

[0039] The bottom of the base frame 1 is provided with a first centering gear set and a second centering gear set corresponding to the two centering motors 5. The first centering gear set includes a driving gear B22, a driven gear B23 and a rotating gear B24. The driving gear B22 is coaxially connected to the output end of the centering motor 5. The rotating gear B24 is respectively meshed with two relatively parallel and spaced racks 26 on the comb tooth frame 2. The driven gear B23 is located between the driving gear B22 and the rotating gear B24. The driving gear B22, the driven gear B23 and the rotating gear B24 are meshed and connected through an annular chain B25. The driven gear B23 is located outside the annular chain B25. The lifting motor 3 drives the driving gear B22 to rotate, thereby indirectly driving the rotating gear B24 to rotate. The rotating gear B24 rotates relative to the two racks 26 during the rotation process, so that the two racks 26 move toward or away from each other, thereby driving the two ends of the comb tooth frame 2 to converge or extend.

[0040] The second centering gear set includes a driving gear C27 and two rotating gears C28, wherein the driving gear C27 is located between the two rotating gears C28, and the driving gear C27 and the two rotating gears C28 are meshed and connected via an annular chain C, and the driving gear C27 is coaxially connected to the output end of the centering motor 5, and the two rotating gears C28 are respectively meshed with two relatively parallel and spaced racks 26 on the comb tooth frame 2, and the centering motor 5 drives the driving gear C27 to rotate, thereby indirectly driving the two rotating gears C28 to rotate, and the rotating gear C28 rotates relative to the two racks 26 during the rotation process, so that the two racks 26 move toward or away from each other, thereby driving the two ends of the comb tooth frame 2 to converge or extend.

[0041] Working principle:

[0042] When the chassis 1 needs to be moved to transport the car, the two travel motors 4 are started. The travel motors 4 cooperate with the gearbox 17 to drive the sprocket A18 and the sprocket B19 to rotate through the ring chain D, thereby driving the travel wheel 20 to rotate. The chassis 1 moves under the drive of the travel wheel 20, and the guide wheel 21 guides the movement of the chassis 1 by contacting the side wall of the parking space, thereby improving the accuracy of the movement of the chassis 1.

[0043] When the comb frame 2 needs to be gathered or opened, two centering motors 5 need to be started, one of which drives the driving gear B22 to rotate, and the driving gear B22 drives the driven gear B23 and the rotating gear B24 to rotate through the ring chain B25. The rotating gear B24 rotates relative to the two racks 26 on the comb frame 2 during the rotation process. The two racks 26 move toward or away from each other during the relative rotation with the rotating gear B24, thereby driving the two sides of one end of the comb frame 2 to gather or open; the other centering motor 5 drives The driving gear C27 rotates, and during the rotation process, the driving gear C27 drives the two rotating gears C28 to rotate through the ring chain C. During the rotation process, the rotating gear C28 rotates relative to the two racks 26 on the comb tooth frame 2. The two racks 26 move toward or away from each other during the relative rotation with the rotating gear C28, thereby driving the two sides of the other end of the comb tooth frame 2 to converge or open. The two centering motors 5 realize the convergence or opening of the two sides of the entire comb tooth frame 2, which is convenient for adjusting its own width according to the model of the car, thereby completing the lifting work of the car.

[0044] When the comb rack 2 needs to lift the car, the lifting motor 3 is started, and the lifting motor 3 drives the driving gear A13 connected to it to rotate. The driving gear A13 drives the remaining two driven gears A14 to rotate through the ring chain A15 during the rotation process, and then drives the driving gear A13 and the two driven gears A14 in the remaining three transmission gear groups to rotate synchronously. The three driving gears A13 drive the three bearings 6 to rotate, and the three bearings 6 drive the guide block 7 to rotate by rotating. The guide block 7 pushes the lifting wheel 9 along the inclined surface of the arc-shaped ramp groove 8 in the rotation process. The lifting wheel 9 rotates and rolls. When the lifting wheel 9 gradually rolls from the lowest point of the arc-shaped slope groove 8 to the highest point of the arc-shaped slope groove 8, the support rod 10 drives the comb tooth frame 2 to complete the rise. When the lifting wheel 9 gradually rolls from the highest point of the arc-shaped slope groove 8 to the lowest point of the arc-shaped slope groove 8, the support rod 10 drives the comb tooth frame 2 to complete the descent. The lifting motor 3 drives the driving gear A13 to change its rotation direction, so that the rotation direction of the bearing 6 can be changed, and then the rotation direction of the guide block 7 can be changed, so that the arc-shaped slope groove 8 can drive the lifting wheel 9 to roll in different directions, thereby realizing the lifting and lowering of the comb tooth frame 2.
