Description

Technical Field

[0001] The utility model relates to an improvement on an elevator door machine structure, in particular to a door machine structure with an integrated frequency converter. Background Art

[0002] The elevator door machine is a working device used to control the opening and closing of the elevator door. The conventional door machine is driven by a variable frequency motor and drives the anti-slip belt. The operation of the belt drives the door leaves to move towards or relative to each other, realizing the opening and closing function of the door. The conventional door machine structure of the variable frequency elevator requires the motor to be installed on the upper part of the door machine, and the belt and other rotating structures need to be connected to the anti-slip belt. The variable frequency motor needs to work with the encoder, so it occupies a large space on the door machine. In addition, more debugging work is required to adjust the door opening gap, door opening distance, etc. Therefore, the installation process of the conventional door machine structure is relatively complicated. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a door machine structure with an integrated frequency converter.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: the door machine structure is fixed on the door lintel as a whole, including a main drive belt, a synchronous belt, a door panel, a drive connecting plate and an integrated frequency converter, the integrated frequency converter is fixed on the door lintel, the integrated frequency converter has a drive output end, the drive output end is connected to the main drive belt, the main drive belt reciprocates on the door opening distance on one side, the synchronous belt is arranged horizontally and corresponds to the door opening distance of the door panel, the relatively working door panels are fixed on the synchronous belt and are respectively arranged in different driving directions of the synchronous belt, and the door panel on one side is connected to the main drive belt through the drive connecting plate. The main control drive structure of the door machine structure is an integrated frequency converter, which has the function of transmitting power and can be directly installed within the working range of the door machine structure to drive the main drive belt linearly. The working distance of the main drive belt is relatively small, and the driving distance requirement of the integrated frequency converter is small. Therefore, the integrated frequency converter can be reduced in size. The main drive belt mainly drives the movement of the door panel on one side, while the door panel on the other side will also move relatively due to the traction of the synchronous belt to realize the mutual opening / closing of the door.

[0005] Furthermore, the integrated frequency converter includes a box body, a PCB board, a motor, and a frequency converter controller. The motor is fixed in the box body. The PCB board has a display module, a communication module, and a door operation module. The motor is controlled by the frequency converter controller to output the power for opening / closing the door. The door operation module carries a control program and controls the operation of the modules on the PCB board. The integrated frequency converter controls the door opening action of the elevator through multiple functional modules on the PCB board and the control program, which involves controlling the direction and speed of the motor, and can centralize the door opening information to realize the external transmission of information, and can adjust the door opening action, optimize the door opening action, and improve the installation efficiency of the door machine.

[0006] Furthermore, the integrated frequency converter is connected to the door lintel through a fixing plate, the fixing plate and the integrated frequency converter are fixed by screws, and the fixing plate is welded and fixed to the door lintel. The integrated frequency converter can be directly installed at a desired position through the fixing plate to achieve linear power output.

[0007] Furthermore, the driving output end of the integrated frequency converter is a synchronous pulley, and the main driving belt is a toothed synchronous belt. The main driving belt is driven by the synchronous pulley to reciprocate over the distance of the single-side door opening. The output end outputs power through the toothed synchronous belt, which has low energy loss and is suitable for the working state of the door opening.

[0008] Furthermore, a traveling chain is connected between the door panel and the lintel panel, and a traveling cable is inserted into the traveling chain. There are devices such as light curtains on the door panel, which need to be connected to the elevator control system. The cable is inserted into the traveling chain to withstand repeated bending.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is a door machine device with an improved driving mechanism, and the driving connection part of the door machine structure is correspondingly improved, so it is suitable for installing an integrated frequency converter, and the volume structure of the door machine is optimized, so that the electronic debugging and installation of the door machine action can be realized, and daily maintenance is convenient, and the working status of the elevator door can be corrected in time.
