An electric-driven scissor-type lifting work platform brake release device, including a power supply, the positive and negative poles of the power supply are connected to the motor control mechanism through wires, the motor control mechanism is connected to the PCU, the PCU is connected to the ECU, and the ECU is connected to the right brake branch respectively. Road, brake output branch, left brake branch, and ground wire, the right brake branch and the left brake branch are respectively connected to the first circuit through a resistor, and the end of the first circuit is connected to the motor control mechanism and the PCU. One end of the second loop is connected to the ground wire, and the other end is connected to the negative pole of the power supply; one end of the third loop is connected to the positive pole of the power supply, and the other end is connected to the ground wire. An emergency brake release switch is arranged on the third loop in turn. A brake release branch is provided on the third circuit, and the brake release branch is respectively connected with the first brake coil, the second brake coil, the left brake branch, and the right brake branch. The device can conveniently and quickly release the brake under the condition of low voltage of the whole machine, which greatly improves the use efficiency of the whole machine.
Description
Technical field: [0001] The invention relates to an electric drive scissor lift working platform releasing braking device. Background technique: [0002] At present, the braking device of the electric-driven scissor lift work platform on the market is an integrated structure with the driving motor. When the driving motor rotates, the braking is released, and vice versa, the motor realizes the braking. The principle of releasing the brake is to open the enable button, press the forward or backward button on the handle, the brake coil is in an electrified state, and an axial force is generated to separate the brake spring from the brake pad, and the brake is released. According to this principle, the electric-driven scissor lift work platform can realize the release of the brake function. In this case, the brake can be released only when the voltage of the whole machine meets the walking function. However, when the whole machine cannot walk or is under low pressure in the wor...
