Background technology
Be arranged on the guardrail outside bridging crane main beam upper end, in maintenance, the fender guard of necessity during maintenance hoisting crane, guardrail is fixed on the upside of crane girder, its height should meet the fixed value that corresponding national safety standard specifies, in most of hoisting crane, namely the vertex of guardrail is the vertex of hoisting crane, the height that tradition plays bridge-type heavy-duty machine guardrail is generally a fixed value, when using the factory building of hoisting crane not at same absolute altitude, during design, the vertex of guardrail should lower than the minimum absolute altitude on roof, this is just for bring inconvenience when the operation of differing heights factory building, and existing overturn guardrail all needs manually to complete, add the labour intensity of workman, improve maintenance, the expense safeguarded, the operating personnel of some awareness of safety weaknesses in addition, even increasing of guardrail is not carried out when carrying out maintenance work, this just adds safety hazard virtually, therefore provide a kind of convenient to use, simple to operate, time saving and energy saving, adaptable New overhead travelling crane guardrail is just very necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of convenient to use, simple to operate, time saving and energy saving, adaptable New overhead travelling crane guardrail.
The purpose of this utility model is achieved in that a kind of New overhead travelling crane guardrail, it comprises girder, the left and right sides of the side surface upper part of described girder is provided with bearing seat, S. A. is connected with between two described side shaft holders, the middle part of described S. A. is provided with big gear wheel, the lower end of described big gear wheel is connected with the miniature gears be meshed with it, the right side of described miniature gears is connected with drive motor, described drive motor is fixed on the side of girder, the upside of described S. A. is connected with guardrail, read-out is provided with in the top of described guardrail, the left and right sides of the bottom of described guardrail is provided with stop collar, the middle and lower part of described girder is provided with the magnetic block matched with stop collar.
Described read-out is LED display.
Described stop collar is arcuate structure.
Described magnetic block is rectangular configuration.
Described drive motor is connected with retarder.
The quantity of described bearing seat is two.
The beneficial effects of the utility model: the connecting portion of guardrail and girder is arranged on the top of girder side by the utility model, drive motor realizes 180 degree of rotations of S. A. and guardrail by gear transmission, what adopt the stop collar of arcuate structure to match with the magnetic block of rectangular configuration is spacing simultaneously, the guardrail turned down under state can obtain good fixation and not affect the normal operation of crane in bridge type, also the factory building of differing heights can better be adapted to, LED display on guardrail can show the operating condition of hoisting crane and scroll safe poster, improve the safety of crane in bridge type, the utility model has with convenient and swift in a word, simple to operate, time saving and energy saving, adaptable advantage.
