DETAILED DESCRIPTION

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] A quick-change rack for supporting wheels, such as Figure 1-Figure 4As shown, it includes a frame 1, a movable panel 2, a sliding member, a lifting member, and a controller 3 fixedly arranged on the frame 1. The movable panel 2 is provided with two mutually symmetrical interlocking grooves 4. The sliding member is provided as a first connector 5 and a second connector 6. The first connector 5 and the second connector 6 are both rotatably provided with a movable wheel group 7, an interlocking wheel group 8 and a driver. The movable panel 2 is provided with a preparatory position 14 and a standby position 15. The preparatory position 14 is provided at one end where the two interlocking grooves 4 are close to each other, and the standby position 15 is provided at the end where the two interlocking grooves 4 are far away from each other. At one end, the first receiving device 5 and the second receiving device 6 need to be respectively set in the preparation position 14 and the standby position 15 area, and set to the initial state of the controller 3. The steps of the quick replacement rack are to first take out the old supporting roller and then load the new supporting roller. In this scenario, the first receiving device 5 is formed to receive the old supporting roller and take it away from the original position. The second receiving device 6 is used for the user to place the new supporting roller. After the old supporting roller is taken away, the second receiving device 6 takes the new supporting roller to the installation position for the user to install the new supporting roller. When installed on the equipment, the position movement of the first adapter 5 and the second adapter 6 is controlled by the controller 3, the driver is configured as an interlocking wheel group 8 plus a first motor 9, and a driving wheel 10 driven by the first motor 9, the first motor 9 and the driving wheel 10 are provided with multiple groups, the interlocking wheel group 8 is configured as an abutting wheel 11 and an interlocking frame 12 that are rotatably connected to each other, the interlocking wheel group 8 is rotatably connected to the first adapter 5 and the second adapter 6 through the interlocking frame 12, a fixing frame 13 is fixedly provided between the interlocking frame 12 and a plurality of first motors 9, and the controller 3 forms corresponding control for different first motors 9, so as to change the position of the first adapter 5 and the second adapter 6 on the movable panel 2. A circuit 16 is formed between the controller 3 and the first motor 9. The circuit 16 penetrates the movable panel 2, the first adapter 5 and the second adapter 6. The controller 3 controls the first motor 9. The circuit 16 forms a connection between the signal and the power supply between the controller 3 and the first motor 9. A battery is arranged in the quick-change rack, which supplies power to the controller 3 and distributes energy by the controller 3.

[0025] The arrangement of the movable wheel group 7, the interlocking wheel group 8 and the driver as a whole on the first connector 5 forms a mirror image with the second connector 6. The first connector 5 and the second connector 6 are respectively embedded in the two interlocking grooves 4 through the interlocking wheel group 8 and the driver arranged thereon, and the two interlocking grooves 4 respectively form displacement path restrictions for the first connector 5 and the second connector 6. The movable wheel group 7 forms an abutment on the movable panel 2. The arrangement of the driver is such that the two interlocking grooves 4 will not cause the movable wheel group 7 to be interlocked with the connector that does not correspond to it, thereby avoiding jamming. At the same time, the embedding of the interlocking wheel group 8 and the driver in the interlocking grooves 4 also guides the displacement of the first connector 5 and the second connector 6.

[0026] A plurality of lifting members are provided and arranged on the frame 1. The plurality of lifting members form displacement control for the movement of the movable panel 2 on the frame 1. The lifting members are configured as a second motor 17, a lead screw 18 and a slider 19. The second motor 17 is fixedly arranged on the frame 1 and drives the lead screw 18. The lead screw 18 and the slider 19 form a lead screw transmission. A plurality of slide grooves 20 for the slider 19 to slide are provided on the frame 1. The slider 19 is fixedly connected to the movable panel 2. The controller 3 controls the second motor 17. The lifting members are provided to adjust the height of the movable panel 2 to adapt to the height of the supporting wheels and enhance the adaptability of the replacement frame.

[0027] The frame 1 is rotatably provided with two fixed wheels 21 and two universal wheels 22, which are respectively arranged at the four corners of the frame 1. The fixed wheels 21 and the universal wheels 22 are arranged so that the user can easily adjust the position of the frame 1.

[0028] The invention also includes a control method of a control system of a quick-change frame of a supporting wheel of the present embodiment, the control method comprising the following steps:

[0029] Step 1: The equipment starts to run, and the controller 3 resets the positions of the first receiver 5 and the second receiver 6. In this step, the controller 3 drives the first motors 9 of the two respectively to push the first receiver 5 to the preparation position 14 and push the second receiver 6 to the standby position 15;

[0030] Step 2: When the controller 3 detects that the first motor 9 is difficult to drive, the controller 3 stops driving the first motor 9;

[0031] Step 3: The user operates the controller 3 to control and drive the second motor 17 to change the height of the movable panel 2;

[0032] Step 4: The user operates the controller 3 to perform subsequent preset operations, the second motor 17 of the controller 3 is driven to lower the control panel, and then the first motor 9 of the first connector 5 is driven to move the first connector 5 to the standby position 15, and the driving is stopped when it is detected that the first motor 9 of the first connector 5 is difficult to drive, and then the first motor 9 of the second connector 6 is driven to move the second connector 6 to the standby position 15, and the driving is stopped when it is detected that the first motor 9 of the second connector 6 is difficult to drive, and finally, the second motor 17 is driven to restore the movable panel 2 to its original height.

[0033] Working principle: During preparation, the user starts the controller 3 to reset the entire device and adjust the height of the movable panel 2, and then the replacement rack can be inserted into the device that needs to replace the supporting roller. The user needs to first align the first adapter 5 with the old supporting roller, unscrew the screws of the supporting roller, and place the new supporting roller on the second adapter 6, and then operate the controller 3 to make the controller 3 execute the operation of step four, and lock the new supporting roller on the equipment after the execution, so as to realize the replacement of the supporting roller.
