Description
Technical field
This utility model relates to Architectural Equipment field, particularly relates to dolly car bumper device and the tower crane comprising this device.
Background technology
Tower crane is paid close attention to by more and more as the main handling equipment of construction, its security performance.Development along with urban construction, the operating mode of construction becomes increasingly complex, especially project near reconstruction of the old city town and power network line, and the barrier such as high-tension bus-bar around construction site is just as a lot of barrier, when construction operation, deal with improperly it is also possible to there is severe safety accident.These potential safety hazards have buried potential safety hazard for production and construction as many time bombs.
When the safe distance of tower crane Yu barrier can not meet code requirement, the range limiter of revolution and amplitude is set by domestic typically taking respectively, i.e. electronic limit mode limits the revolution of tower crane, jib lubbing mechanism, is set revolution and amplitude stop respectively according to field condition and condition.Limit angle of revolution and the operation amplitude of tower crane.Revolution and amplitude stop be safe finally together with barrier.
The poor reliability of above-mentioned stopping means, when the unexpected power-off of emergency situations such as tower crane, brake failure, it is impossible to control effectively.If revolution or amplitude stop are malfunctioning, it is most likely that cause hoist cable or hang thing and touch the danger of high-tension line.In order to keep the safety in production and the safe operation of tower crane, prevent contingency from occurring, it is necessary to take effective feasible safeguard procedures.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of dolly car bumper device and the tower crane comprising this device.Dolly car bumper device simple in construction of the present utility model, dismounting, flexible and convenient operation, can arrange in any amplitude according to field condition, use electronics and the protection of machinery dual luffing fiber, general safety is reliable.
Concrete technical scheme of the present utility model is: a kind of dolly car bumper device, including mounting seat and car bumper frame, described mounting seat is for being connected with the lower main string of the crane arm of tower crane, described car bumper frame is fixed on the upper surface of described mounting seat, described mounting seat is provided with travel switch towards the one side of dolly, and described travel switch is towards the triggering rocking bar being provided with dolly in the one side of dolly.
As preferably, described car bumper frame is provided with cushion pad towards the one side of dolly.The effect of cushion pad is to play cushioning effect, and anti-locking apparatus is damaged.
As preferably, the distance of described cushion pad to dolly is more than the distance of described triggering rocking bar to dolly.It is arranged such and is able to ensure that triggering rocking bar first touches with dolly.
As preferably, described mounting seat is fixed on the lower main string of crane arm by bolt A.
As preferably, described cushion pad is fixed on described car bumper frame by bolt B.
A kind of tower crane, comprises above-mentioned dolly car bumper device.
As preferably, described tower crane is additionally provided with loudspeaker,
Described loudspeaker, travel switch join even with the jib lubbing mechanism of tower crane respectively.When, after dolly touching travel switch, jib lubbing mechanism can control loudspeaker and blow a whistle sound, it is possible to play warning function.
As preferably, under two of the crane arm of described tower crane, on main string, it is respectively provided with a set of described dolly car bumper device.
As preferably, said two set dolly car bumper device is identical with the distance of dolly.Two set dolly car bumper devices are necessary to ensure that alignment, it is ensured that when dolly travels to car bumper, two set car bumper devices are touched in the front end of dolly simultaneously.Two such travel switch can effectively prevent dolly from burning out the danger of motor after being stopped by car bumper device, even if any one is malfunctioning in two travel switches, another can also work.
This utility model operation principles is: when dolly moves to the amplitude of setting, two set dolly car bumper devices are touched in the front end of dolly simultaneously.The touching rocking bar of the travel switch of two set car bumper devices is touched, and program can control jib lubbing mechanism and cut off dolly forward motion, is simultaneously emitted by sound warning of blowing a whistle, but the backward movement of dolly is unrestricted.Two such travel switch can effectively prevent dolly from burning out the danger of motor after being stopped by car bumper device.
This utility model takes bolt connecting mode, convenient and flexible installation on main string under crane arm, does not damage crane arm steel construction, and can install at an arbitrary position.The insurance design of electronic type, mechanical double.Electronic type use two travel switches, one malfunctioning time another also can act.Dolly car bumper device uses frame for movement, can effectively prevent trolley travelling amplitude beyond margin of safety.What the cushion pad on dolly car bumper device can play when dolly is touched with car bumper soft contacts function.More than design simple and reasonable, flexible and convenient operation, can arrange in any amplitude according to field condition, general safety is reliable.
Being compared with the prior art, the beneficial effects of the utility model are:
Device the most of the present utility model can arrange luffing spacing according to on-the-spot actual state at any amplitude, install, dismantle, regulate easy to operate, flexible arrangement.Eliminate safe hidden trouble, provide guarantee for safe construction.
2. use electronics and machinery dual luffing position limitation protection, more safe and reliable.
3. car bumper device uses split design, and bolt connects, do not destroys crane arm steel construction.
