Abstract

The utility model discloses a rope breaking prevention device for a traveling trolley of a tower crane, and particularly relates to the technical field of mechanical safety devices. The rope breaking prevention device comprises a baffle, an ear plate, a hinge pin, a metal ring and a bolt and is characterized in that the baffle comprises a heavy head end and a light head end, wherein the baffle is mounted on the ear plate through the hinge pin; the ear plate is welded on the traveling trolley; a steel wire rope passes through the metal ring; the heavy head end of the baffle is heavier than the light head end of the baffle; the metal ring is welded on the bolt; the bolt is fixedly connected with the light head end of the baffle. The rope breaking prevention device disclosed by the utility model is simple in structure and convenient to mount, can effectively prevent the problem of sliding of the trolley after rope breaking, and is particularly suitable for a tower crane.

Description

Tower crane amplitude variation trolley Anti-breaking rope device
Technical field
The utility model relates to a kind of mechanical safety device technical field, especially a kind of tower crane amplitude variation trolley Anti-breaking rope device.
Background technology
The steel rope of tower crane amplitude variation trolley is after long work, usually due to wearing and tearing or fatigue again or operator's violation operation, cause amplitude variation trolley wire cable rupture, amplitude variation trolley is at inertia and hanging under the Action of Gravity Field that thing is huge, operation forward, break through block foremost, dolly integral body comes off, and easily causes the accident.The amplitude variation trolley protection device for preventing wire rope breaking using is at present by coupler body; bearing pin; pouring weight forms; effect by gravity makes coupler body hook crane arm web member; in use procedure, coupler body can not well hook crane arm web member sometimes; can not stop trolley travelling by actv.,, there is certain potential safety hazard in job insecurity.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tower crane amplitude variation trolley Anti-breaking rope device.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of tower crane amplitude variation trolley Anti-breaking rope device, comprise baffle plate, otic placode, bearing pin, metal ring and bolt, it is characterized in that described baffle plate comprises baffle plate accent end and the light head end of baffle plate, described baffle plate is arranged on described otic placode by described bearing pin, and described otic placode is welded on amplitude variation trolley, and steel rope passes from described metal ring.
The weight of described baffle plate accent end is greater than the weight of the light head end of described baffle plate.
Described metal ring is welded on described bolt, and described bolt is fixedly connected on the light head end of described baffle plate.
The beneficial effect that adopts technique scheme to produce is: the utility model is when variable-amplitude steel wire rope ruptures, the light head end of baffle plate departs from the restriction of bolt metal ring and steel rope, under the effect of baffle plate accent end gravity, the light head end of baffle plate upwarps, around bearing pin, rotate, the light head end of baffle plate is subject to stopping of crane arm web member, thereby prevents the row that slips of dolly.The utility model is simple in structure, easy for installation, can actv. prevents that dolly from slipping capable problem after disconnected rope, is specially adapted to tower crane and installs and uses.
Below in conjunction with embodiment and accompanying drawing, described in detail, but not as to further restriction of the present utility model.
Accompanying drawing explanation
Fig. 1 is the utility model integral structure schematic diagram;
Fig. 2 is the structural representation of the utility model baffle plate.
As illustrated in figs. 1 and 2: 1 baffle plate, 2 otic placodes, 3 bearing pins, 4 metal rings, 5 bolts, the light head end of 1-1 baffle plate, 1-2 baffle plate accent end.
The specific embodiment
As depicted in figs. 1 and 2, the utility model is a kind of tower crane amplitude variation trolley Anti-breaking rope device, comprise baffle plate 1, otic placode 2, bearing pin 3, metal ring 4 and bolt 5, it is characterized in that described baffle plate 1 comprises baffle plate accent end 1-2 and the light head end 1-1 of baffle plate, described baffle plate 1 is arranged on described otic placode 2 by described bearing pin 3, described otic placode 2 is welded on amplitude variation trolley, steel rope passes from described metal ring 4, the weight of described baffle plate accent end 1-2 is greater than the weight of the light head end 1-1 of described baffle plate, described metal ring 4 is welded on described bolt 5, described bolt 5 is fixedly connected on the light head end 1-1 of described baffle plate.
Under normal mode of operation, be through the rotation that steel rope in bolt metal ring has limited baffle plate, whole baffle plate is in state of equilibrium, and after wire cable rupture, this state of equilibrium is broken, the light head end of baffle plate departs from the restriction of bolt metal ring and steel rope, under the effect of baffle plate accent end gravity, the light head end of baffle plate upwarps, and around bearing pin, rotates, the light head end of baffle plate is subject to stopping of crane arm web member, thereby prevents the row that slips of dolly.The utility model is simple in structure, easy for installation, can actv. prevents that dolly from slipping capable problem after disconnected rope, is specially adapted to tower crane and installs and uses.
