Foot-operated lifting system

Abstract

A foot-operated lifting system, installed on a rebar bending machine, includes a base whose bottom surface is connected to the rebar bending machine; a lifting arm mounted on the base with a lifting unit; and a foot switch electrically connected to the lifting unit to raise or lower the lifting arm. This invention allows users to control the picking or unloading of rebars with a foot switch, saving time on manual handling and increasing the efficiency of bending rebars.

Claims

1. A foot-operated lifting system installed on a rebar bending machine, the foot-operated lifting system comprising: a base with its bottom surface connected to the rebar bending machine; a lifting arm mounted on the base with a lifting unit; and a foot switch electrically connected to the lifting unit to lift the lifting arm.

2. The foot-operated lifting system as described in claim 1, wherein the base is further provided with a transverse roller electrically connected to the foot switch, the transverse roller rolling in a direction parallel to the extension direction of a steel bar entering the steel bar bending machine.

3. The foot-operated lifting system as described in claim 2, wherein the rebar bending machine has a stop facing the transverse roller.

4. The foot-operated lifting system as described in claim 1, wherein the rebar bending machine picks up material from above.

5. The foot-operated lifting system as described in claim 1, wherein the lifting arm includes a hook and a lever mounted in the middle of the hook, the lever being higher than the hook, the lever having an inclined surface facing the hook, such that when the lifting arm is raised and the lever lifts at least one steel bar, the steel bar slides along the inclined surface into the tail end of the hook.

6. The foot-operated lifting system as described in claim 1, wherein one end of the lifting arm is pivotally connected to the base, and the lifting unit is disposed between the middle section of the lifting arm and the base, such that when the lifting unit extends or retracts, it causes the end of the lifting arm not pivotally connected to the base to swing up and down.

7. The foot-operated lifting system as claimed in claim 1, wherein the lifting unit is a pneumatic rod containing a solenoid valve, and the foot switch is electrically connected to the solenoid valve.
