Abstract
The utility model relates to a tower crane becomes width of cloth dolly stop device, including setting up in the frid of the upper and lower side of jib loading boom lower chord, the coupling mechanism who lays through a plurality of interval between two frids is connected, and the both sides end that is located two frids is provided with the blotter respectively. Not only simple structure has overcome moreover and must set up protection canopy or the spacing drawback of gyration when the tower machine is interfered with the high -voltage line.
Description
Technical field
The utility model relates to a kind of tower crane amplitude variation trolley stopping means.
Background technology
In normal conditions, tower crane amplitude variation trolley can be the most movable on crane arm lower boom, part construction
Project is at equipment erection stage, due to tower crane limited height, it is impossible to meet the safe distance of high-voltage line, need to arrange protector.
Typically taking set up protection canopy or tower crane carries out the way of slewing limit, this kind of way is not only time-consuming, and costly, dismounting
Difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of tower crane amplitude variation trolley stopping means, is not only simple in structure,
And overcome the drawback that must set up protection canopy or slewing limit with high-voltage line when tower crane is interfered.
The technical solution of the utility model is: a kind of tower crane amplitude variation trolley stopping means, including being arranged at
The frid of the upper and lower side of weighing arm lower boom, the bindiny mechanism laid through several intervals between two frids is connected, and is positioned at two frids
Two side ends be respectively arranged with cushion pad.
Further, the opposing setting of notch of described frid, two frids are correspondingly arranged on along its length some logical
Hole.
Further, described bindiny mechanism includes from bottom to top through the connecting bolt of the through hole on two frids, described company
It is provided with stop nut on the threaded end of connecting bolt.
Further, described cushion pad is fixed through connector and frid and is connected.
Compared with prior art, the invention have the advantages that and be not only simple in structure, and make tower crane amplitude variation trolley exist
Work under conditions of meeting high-voltage line safe distance, both need not set up protection canopy without carrying out spacing to revolution, overcome tower
Machine must set up the drawback of protection canopy or slewing limit with high-voltage line when interfering.Not only economy but also facilitate, treats that tower crane uses the fullest
During foot high-voltage line safe distance, this device is removed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 10-top boom 20-lower boom 30-brace 40-frid 51-connecting bolt 52-stop nut 60-
Cushion pad.
Detailed description of the invention
For features described above of the present utility model and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below, but the utility model is not limited to this.
With reference to Fig. 1
A kind of tower crane amplitude variation trolley stopping means, including top boom under crane arm 10, lower boom 20, under crane arm
Chord member is connected to form stable triangular structure through the top boom of two braces 30 and crane arm is fixing.Described crane arm lower boom
Upper and lower side is respectively provided with slot plate 40, and the bindiny mechanism laid through several intervals between described two frids is connected, and is positioned at two
The two side ends of frid is respectively arranged with cushion pad 60.
In the present embodiment, the opposing setting of notch of described frid, two frids are correspondingly arranged on along its length some
Through hole.
In the present embodiment, described bindiny mechanism includes from bottom to top through the connecting bolt 51 of the through hole on two frids, institute
State and on the threaded end of connecting bolt, be provided with stop nut 52.
In the present embodiment, described cushion pad is fixed through connector and frid and is connected.
The foregoing is only preferred embodiment of the present utility model, all according to the utility model claim done equal
Deng change and modification, covering scope of the present utility model all should be belonged to.
