Further, the electric push rod is a trapezoidal screw electric push rod.
Further, the hinge shaft connecting rod and the hinge shafts on the first hinge seat and the third hinge seat are integrally formed.
The working principle of the invention is as follows: in the motion process of the elevator stopping, when the elevator moves to a certain landing, the elevator firstly moves to a position higher than the flat layer position of the certain landing, the position 50mm above the flat layer position is stopped slightly, the lead screw of the electric push rod stretches out under the drive of the motor, the hinge shaft connecting rod is driven to rotate through the cam fixed on the hinge shaft connecting rod, the locking rods on two sides of the locking rod connecting rod are driven to rotate to a supporting working position, the electric safety device measures the rotation angle of the hinge shaft connecting rod, and after the locking rod is calculated and judged to rotate to the supporting position of the fixed seat, the elevator moves to the flat layer position at the flat layer speed, and the elevator opens a landing door. The electrical safety device and the technical scheme for measuring the rotation angle of the hinge shaft and the connecting rod thereof all adopt the technical scheme known in the prior art, such as an angle sensor, which is known by those skilled in the art, and are not repeated herein.
In the starting action process of the elevator, when the elevator is started, the elevator firstly runs upwards at the flat layer speed by about 50mm, the electric push rod retracts into the screw rod, the cam fixed on the hinge shaft connecting rod drives the hinge shaft connecting rod to rotate, the locking rods on two sides of the locking rod connecting rod are driven to rotate to a non-working state, and after the electric safety device measures the rotation angle of the hinge shaft connecting rod and judges that the locking rod is positioned at the non-working state position through calculation, the elevator runs upwards or downwards according to the running instruction.
Compared with the prior art, the invention has positive and obvious effects. Through setting up strutting arrangement in car frame underbeam and each layer flat bed position department, the car floor slope problem that the circumstances such as uneven appears is placed because the goods weight is big when having solved the elevator loading condition, this elevator car flat bed position strutting arrangement simple structure, the reliability is high, has effectively ensured the safety of goods and personnel.
