Technical Field

[0001] The utility model relates to a lifting device, in particular to an electroplating crane lifting device. Background Art

[0002] The electroplating crane is an automated device used to transport workpieces to the electroplating station on the electroplating production line and to remove the electroplated workpieces from the electroplating station. It mainly includes a walking device and a lifting device. At present, the lifting device of the electroplating crane mostly adopts a screw structure. The forward and reverse rotation of the screw drives the lifting seat and the plated workpiece to rise and fall. The forward, reverse and stop of the screw are all controlled by a travel switch.

[0003] A travel switch is a commonly used low-current main control electrical appliance. It uses the collision of the moving parts of the production machinery to make its contacts move, so as to connect or disconnect the control circuit and achieve a certain control purpose. Usually, this type of switch is used to control the travel and limit protection of mechanical equipment. However, the current travel switch is generally fixed in position. When the travel height needs to be adjusted, the travel switch needs to be disassembled, adjusted in position, and then reinstalled, which is cumbersome to operate, lacks applicability, and is not conducive to use. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an electroplating crane lifting device, which effectively solves the problem that the current travel switch is generally fixed in position. When the travel height needs to be adjusted, the travel switch needs to be disassembled and the position adjusted and then reinstalled, which is cumbersome to operate, lacks applicability, and is not conducive to use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes parallel support frames arranged on both sides and a crossbeam arranged on the top of the support frame, and also includes a first screw rod, a guide column, a first motor, a first lifting block, a lifting beam, a lifting rod and an auxiliary component, wherein a first screw rod is installed in the middle of the support frame, guide columns are symmetrically fixed on both sides of the first screw rod, a first motor is installed on the top of the first screw rod, a first lifting block is installed on the first screw rod and the guide column, a lifting beam is installed on the first lifting block, a lifting rod is installed on the bottom end of the lifting beam, and auxiliary components are arranged on both sides of the support frame located at the first lifting block;

[0006] The auxiliary component includes a groove, a second screw rod, a second lifting block, a travel switch, a second motor, a second wire hole, a guide hole and a first wire hole. The groove is opened at the edge of the support frame, a second screw rod is installed inside the groove, a second lifting block is installed on the second screw rod, a travel switch is installed on the second lifting block, and a second motor is installed on the top end of the second screw rod.

[0007] Preferably, the bottom end of the lifting rod is connected and fixed to the electroplating crane.

[0008] Preferably, scale lines are provided on the support frame at the edge of the groove.

[0009] Preferably, a second thread hole is formed in the second lifting block at a position corresponding to the second threaded rod.

[0010] Preferably, a guide hole is provided at a position of the first lifting block corresponding to the guide column.

[0011] Preferably, a first thread hole is formed in the first lifting block at a position corresponding to the first threaded rod.

[0012] The lifting of the second lifting block drives the lifting beam and the lifting rod to rise, thereby lifting the electroplating crane (this is the prior art). When the first lifting block is lifted to the upper stroke switch position, the stroke switch controls the first motor to stop working, that is, the lifting height is positioned. When the first lifting block is lowered to the upper stroke switch position, the stroke switch controls the first motor to stop working, that is, the lowering height is positioned. When the height positioning of the crane needs to be adjusted, the second motor works, and the second motor drives the second screw rod to rotate.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 The specific implementation modes of the present utility model are further described in detail.

[0019] Embodiment 1, by Figure 1-3 The utility model provides an electroplating crane lifting device, comprising a parallel support frame 1 arranged on both sides and a crossbeam 2 arranged on the top of the support frame 1, and also comprising a first screw rod 3, a guide column 4, a first motor 5, a first lifting block 6, a lifting beam 7, a lifting rod 8, an auxiliary component 9, a groove 10, a second screw rod 11, a second lifting block 12, a travel switch 13, a second motor 14, a second wire hole 15, a guide hole 16 and a first wire hole 17. The first screw rod 3 is installed in the middle of the support frame 1, and the guide columns 4 are symmetrically fixed on both sides of the first screw rod 3. The first motor 5 is installed on the top of the first screw rod 3, the first lifting block 6 is installed on the first screw rod 3 and the guide column 4, the lifting beam 7 is installed on the first lifting block 6, and the lifting rod 8 is installed on the bottom end of the lifting beam 7. The support frame 1 is provided with auxiliary components 9 on both sides of the first lifting block 6;

[0020] The auxiliary component 9 includes a groove 10, a second screw rod 11, a second lifting block 12, a travel switch 13, a second motor 14, a second wire hole 15, a guide hole 16 and a first wire hole 17. The groove 10 is opened at the edge of the support frame 1, and the second screw rod 11 is installed inside the groove 10. The second lifting block 12 is installed on the second screw rod 11. The travel switch 13 is installed on the second lifting block 12. The second motor 14 is installed at the top of the second screw rod 11, and the travel switch 13 is electrically connected to the first motor 5.

[0021] Specific use: When the utility model is used, the first motor 5 drives the first screw rod 3 to rotate. The first screw rod 3 rotates. The first screw rod 3 rotates and cooperates with the first wire hole 17 opened on the first lifting block 6, so that the first lifting block 6 rises on the first screw rod 3. The rise of the first lifting block 6 drives the lifting beam 7 and the lifting rod 8 to rise, thereby lifting the electroplating crane (this is the prior art). When the first lifting block 6 is lifted to the position of the upper travel switch 13, the travel switch 13 controls the first motor 5 to stop working, that is, the lifting height is positioned, and the first lifting block 6 is lifted to the upper position. When block 6 descends to the position of the upper travel switch 13, the travel switch 13 controls the first motor 5 to stop working, that is, to lower the height positioning. When the height positioning of the crane needs to be adjusted, the second motor 14 works, and the second motor 14 drives the second screw rod 11 to rotate. The rotation of the second screw rod 11 cooperates with the second wire hole 15 opened on the second lifting block 12, so that the second lifting block 12 moves on the second screw rod 11. The lifting and lowering of the second lifting block 12 drives the travel switch 13 to move, so as to achieve the purpose of adjusting the lifting and lowering height of the lifting rod 8, which is convenient for use.
