Embodiment Construction

[0048] Refer to attached Figure 1-5 , the main embodiments of the present invention are described in detail here.

[0049] Such as figure 1 As shown, the manual barring device 100 of the present invention includes a barring handwheel 1, a worm 2, a worm wheel 3 and a bracket 4, wherein the worm 2 is installed in the bracket 4, and the barring handwheel 1 is fixedly mounted on on the worm 2, and by manually turning the turning hand wheel 1, the worm 2 can be driven to rotate, and then the worm 2 can drive the worm wheel 3 to rotate.

[0050] The main difference with the technical solution disclosed in the prior art, especially the patent document CN2892785, is:

[0051] In the present invention, the worm gear 3 is installed in the bracket 4; while in the patent document CN2892785, the worm gear is directly installed on the extension end of the motor shaft of the traction machine or on the traction wheel linked with the motor shaft. In the present invention, the transmission...

Abstract

The invention relates to a hand-barring device (100) which comprises a handwheel (1), a worm (2), a worm gear (3) and a support (4) and is characterized in that the worm gear (3) is installed in the support (4), the hand-barring device (100) further comprises at least one transmission pillars (5) and at least one corresponding transmission hole (51), the transmission pillars (5) are connected with the worm gear (3), the transmission holes (5) are correspondingly distributed on a rotary wheel (300) to be driven by the hand-barring device (100), and the hand-barring device (100) can drive the rotary wheel to rotate by inserting the transmission pillars (5) into the corresponding transmission holes (51) and fixing the support (4) on a machine frame (200). The hand-barring device is simple in structure, low in cost, detachable, and capable of realizing self-locking and high torque. The invention further relates to an elevator comprising the hand-barring device.

Description

technical field [0001] The present invention relates to the driving mechanism (B66B 11 / 04) of the elevator, in particular to the manual cranking device of the elevator. The invention also relates to an elevator comprising said manual barring device. Background technique [0002] When the elevator traps passengers in the elevator due to power failure or failure, if the car is not at the leveling position and the trapped passengers cannot be released by opening the landing door, it is necessary to turn the traction sheave by other methods to move the elevator to the leveling position. Release the passengers. One of the methods is to turn the traction sheave through the barring device to manually realize the elevator operation. [0003] The requirement for the manual cranking device in the elevator standard is that the required operating force is not greater than 400N. When the load increases, the operating force required for the cranking will also increase. When the operatin...
