The railing crosspiece 5-3 is connected between the adjacent telescopic railing posts 5-1, and the design is to protect constructors and prevent falling accidents. The net distance between the bottommost railing crosspiece 5-3 and the upper end face of the platform 5-2 is not more than 230mm, and the railing crosspiece cannot slide out of the maintenance platform 5 even if constructors slide down according to the human engineering design. The protection plate 5-4 is hinged with the platform 5-2, the protection plate 5-4 is arranged on the outer side of the telescopic railing post 5-1, and the protection plate and the telescopic railing post are connected through the protection chain 5-5. Because the distance is reserved between the pier 11 or the guard rail 13 and the maintenance platform 5, the operation of constructors is not facilitated, the arrangement of the guard plates 5-4 and the guard chains 5-5 effectively solves the problem, the guard plates 5-4 can be laid down to be in lap joint with the pier 11 or the guard rail 13 during construction, and the guard plates 5-4 are firmly fixed with the telescopic railing posts 5-1 through the guard chains 5-5 to prevent sliding. Therefore, the distance between the pier 11 or the guard rail 13 and the maintenance platform 5 is provided with an effective platform, and convenience is brought to the operation and construction of constructors.
The balustrade 5-3 is arranged inside the second lifting mechanism 2, which makes the construction personnel safer.
Referring to fig. 1, a protective barrier is additionally arranged on the other side of the stowage bin 3-3, and a warning lamp and a leftward driving indicator lamp are arranged at the top of the protective barrier. The vehicle warning and guiding device can effectively warn and guide passing vehicles, and further protect the safety of construction personnel better.
The utility model discloses a travelling car 3 can remote control operation with maintenance platform 5.
The utility model discloses a use is:
utilize haulage vehicle will the utility model discloses transport to the construction position, the uninstallation the utility model discloses afterwards, haulage vehicle drives away from, effectively reduces the influence to the traffic. Constructor steps on and takes advantage of the utility model discloses afterwards, an operating personnel stays operate on the spot on travelling car 1 the utility model discloses, all the other personnel 2-4 people pass through transfer platform 4 shifts to in the maintenance platform 5. Operate on the spot the utility model discloses, rise first elevating system 1 makes overhaul platform 5 is higher than behind the protection railing, remove left travelling car 3 treats spacing round 3-2 effect back, stop moving, operate on the spot second elevating system 2 descends, makes constructor follow overhaul platform 5 and fall to the construction position, and during the period constructor will flexible railing post 5-1 mentions to protect oneself. And (3) putting down the protection plates 5-4, overlapping the protection plates with the piers 11 or the protection railings 13, fixing the protection plates through the protection chains 5-5, and starting construction after safety is determined.
Retrieve this utility model: remote control operation second elevating system 2 rises, takes constructor shifts to behind the transfer platform, operate first elevating system 1 descends, and personnel shift then to the safety zone, will utility model shifts to behind the transport vechicle, drives away from the construction site.
