Description

Technical Field

[0001] The utility model relates to the field of support frames, in particular to a synchronous lifting device. Background Art

[0002] Copper tubes in a continuous m shape are distributed at the top of the radiator. If the copper tubes are to be welded to the top of the radiator, it is necessary to ensure that the radiator stands on the chain conveyor line at least at a certain inclination angle, and then use manual labor or welding equipment to weld the copper tubes to the top of the radiator. At present, in order to ensure that the radiator stands on the chain conveyor line at a certain inclination angle, at present, a support frame is installed on one side of the chain conveyor line. One side of the support frame facing the chain conveyor line includes at least two horizontal support rods, which are arranged up and down, and the distances between the two horizontal support rods and the side of the support frame are not equal, thus forming an inclined plane for supporting the radiator, so that it can be ensured that the radiator runs on the chain conveyor line at a certain inclination angle without tipping over. However, at present, at least two horizontal support rods are fixed and locked to the support frame by screws. When the inclination needs to be adjusted, only manual adjustment can be carried out. Since the support frame and the horizontal support rods are arranged along one side of the chain conveyor line and have a long length, if adjustment is needed, it is time-consuming and laborious, and it is difficult to ensure the consistency of the adjusted height of the horizontal support rods.

[0026] Refer to Figures 1-10 As shown, this embodiment discloses a synchronous lifting device, including a base 1, on which a plurality of longitudinal support rods 2 are fixed. On the same side of the plurality of longitudinal support rods 2, an upper horizontal support rod 3 and a lower horizontal support rod 4 are connected. The distance between the upper horizontal support rod 3 and the plurality of longitudinal support rods 2 is less than the distance between the lower horizontal support rod 4 and the plurality of longitudinal support rods 2. The lower horizontal support rod 4 is fixed on the plurality of longitudinal support rods 2. A plurality of upper clamping members 5 are arranged on the upper horizontal support rod 3. The number of the plurality of upper clamping members 5 is the same as the number of the longitudinal support rods 2. A lead screw sleeve 6 is arranged at the free end of each upper clamping member 5. The upper end to the middle of the longitudinal support rod 2 is a lead screw section 2a. The lead screw sleeve 6 is sleeved on the lead screw section 2a and is in threaded cooperation with it. A servo motor 7 for driving the upper horizontal support rod 3 to which the longitudinal support rod 2 is connected to lift is arranged on the base 1.

[0027] In some embodiments, multiple servo motors 7 may be provided, that is, each longitudinal support rod 2 is driven by a servo motor 7. However, this results in a higher cost and it is difficult to maintain consistent synchronization.

[0028] Therefore, in this embodiment, one servo motor 7 is provided, and one servo motor 7 drives multiple longitudinal support rods 2 to rotate synchronously through a synchronous transmission assembly. Specifically, as Figures 7-9 shown, the synchronous transmission assembly includes a main transmission sprocket 8 provided on the output shaft of the servo motor 7, a slave transmission sprocket 9 provided on one of the longitudinal support rods 2, and a first secondary slave sprocket 10 and a second secondary slave sprocket 11 provided on each longitudinal support rod 2. A main transmission chain 12 is sleeved on the main transmission sprocket 8 and the slave transmission sprocket 9, a first secondary transmission chain 13 is sleeved on every two adjacent first secondary slave sprockets 10, and a second secondary transmission chain 14 is sleeved on every two adjacent second secondary slave sprockets 11.

[0029] As Figure 8 、 Figure 9 shown, the lower end of the longitudinal support rod 2 is provided on the base 1 through at least two bearings 15, and the two bearings 15 are distributed at the upper and lower ends of the base 1.

[0032] The working principle of this embodiment is:

[0033] When it is necessary to adjust the upper horizontal support rod 3, start the servo motor 7 to drive the main drive sprocket 8 to rotate. It rotates to the slave drive sprocket 9 through the main drive chain 12. The lower end of the longitudinal support rod 2 installed with the slave drive sprocket 9 drives the longitudinal support rod 2 on one side to rotate synchronously through the cooperation of two adjacent first sub-driven sprockets 10 and the first slave drive chain 13, and also drives the longitudinal support rod 2 on the other side to rotate synchronously through the cooperation of two adjacent second sub-driven sprockets 11 and the second slave drive chain 14, and so on. Then, through the two first sub-driven sprockets 10 and the first slave drive chain 13, and the two second sub-driven sprockets 11 and the second slave drive chain 14, the remaining longitudinal support rods 2 are driven to rotate synchronously, and then force the plurality of screw sleeves 6 to move up and down on their corresponding screw segments 2a. Finally, the height of the upper horizontal support rod 3 is adjusted, and then the angle of the support slope formed by the upper horizontal support rod 3 and the lower horizontal support rod 4 is adjusted to be suitable for the installation of radiators under different working conditions or of different types and sizes.
