The utility model discloses the dismouting is nimble convenient, and the card key card is gone into the corresponding notch of the last flange face of the upper fixed plate of L frame and swing motor simultaneously, and the card key can prevent the impact load that inertia arouses, and the effectual screw of having avoided bears shearing force and moment of flexure.
Description
Technical Field
The utility model relates to an aerial working car accessory technical field, concretely relates to high altitude platform work fence swing motor fixed knot constructs.
Background
The aerial work platform comprises an arm support arranged on the vehicle body and a working column arranged at the tail end of the arm support, workers enter the working column, and the working column and the workers are conveyed to a high position through the arm support to carry out aerial work. In order to better adjust the working column, the working column is connected with the arm support through the swing motor, and when the adjustable working column is used, the working column can rotate left and right, so that the position of the working column is adjusted.
For example, in a fixing structure of a swing motor in a weighing device applied to an aerial work platform of patent No. CN201220281159.1, a fixing form of a conventional swing motor and a swing motor fixing frame is only fixed by a circle of socket head cap screws and a central fixing long shaft, and this fixing form is easy to break a circle of fixing screws because the swing motor sometimes has a relatively high swing speed and a relatively large inertia during operation of loading a working boom, which easily causes impact load during swing, while the fixing screws generally can bear a relatively large pulling force but have relatively weak resistance to shearing force and bending moment, and once subjected to a transverse impact load for a long time, the fixing screws are easy to bend or shear.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide a high altitude platform work fence swing motor fixed knot and construct, the dismouting is nimble convenient, and the card key card is gone into the corresponding notch of the upper fixed plate of L frame and swing motor's last flange face simultaneously, and the card key can prevent the impact load that inertia arouses, and the effectual screw of having avoided bears shearing force and moment of flexure.
The purpose of the utility model is realized like this:
the utility model provides a high altitude platform work bar swing motor fixed knot constructs, includes work bar, L frame and swing motor, L frame sets up the below at the work bar, L frame includes parallel arrangement's upper fixed plate and bottom plate, swing motor arranges in between the upper and lower fixed plate, and the fixed major axis of swing motor center is from last to screw up through flat pad, nut after down passing upper fixed plate, swing motor and bottom plate in proper order, it is equipped with the card key still to overlap on the fixed major axis of swing motor center, the fixed major axis of swing motor center is gone into the corresponding notch of upper fixed plate and swing motor's upper flange face with the card key card simultaneously, the upper fixed plate still is fixed through set screw with swing motor's upper flange face.
Preferably, the clamping key is provided with a plurality of key-shaped bulges.
Preferably, the clamp key is provided with four key-shaped protrusions which are uniformly distributed in the circumferential direction of the clamp key.
The utility model has the advantages that:
the utility model discloses the dismouting is nimble convenient, and in the upper fixed plate of L frame and the corresponding notch of swing motor's last flange face was gone into to the card key while card, the impact load that the card key can prevent inertia and arouse, and the effectual screw of having avoided bears shearing force and moment of flexure, has prolonged the life of screw.
