Abstract
The utility model relates to a load-bearing trolley, in particular to the load-bearing trolley of a tower crane with a car slipping prevention device during rope breaking, which consists of a frame, rolling wheels, a frame cross beam, a pulley block, a traction device and the car slipping prevention device, wherein the rolling wheels are mounted at four corners of the frame, the pulley block is mounted on the frame cross beam, the traction device and the car slipping prevention device are mounted on one side of the pulley block, and the car slipping prevention device consists of a safety gate plate, a stop lever, a balancing weight and the like and is welded on the frame cross beam through an ear plate seat. When a variable amplitude steel wire rope is broken, the load-bearing trolley can lead the stop lever to drive the safety gate plate to turn by 90 degrees, be further erected and be vertical to the frame under the gravity of the balancing weight, thereby leading the safety gate plate to be blocked by a horizontal web member on the bottom side of an arm support and further preventing the load-bearing trolley from slipping. The load-bearing trolley can solve the problem that the existing load-bearing trolley slips forwards under the inertia action and causes production accidents when the variable amplitude steel wire rope is broken, has novel design and simple structure, and is particularly applicable to mounting and use of the tower cranes.
Description
Technical field:
The utility model relates to a kind of load-carrying dolly, is specifically related to a kind of tower crane load-carrying dolly with disconnected rope anti roll device.
Background technology:
Tower crane load-carrying dolly is the vitals on the tower crane tool equipment, and its four jiaos respectively are equipped with four rolling and four side wheels, are wound with two steel ropes that length is different on the luffing mechanism, fix with load-carrying dolly two ends respectively.The load-carrying dolly can seesaw along crane arm brachium direction under the luffing rope traction of lifting luffing mechanism.Tower crane is in the operation that lifts weight, if the phenomenon of disconnected rope appears in the luffing steel rope, the load-carrying dolly can and hang under the effect of thing gravity at inertia and travel forward, and breaks through the block of leading portion, load-carrying dolly integral body is come off and causes industrial accident.
Summary of the invention:
The purpose of this utility model is: a kind of load-carrying dolly that safe flashboard and pin are installed is provided, when load-carrying carriage amplitude varying wire cable rupture, pin loses and supports the back drive safe flashboard tipped upright under the effect of clump weight, makes safe flashboard be subjected to resistance from the horizontal web member in jib bottom side and stops to slip the tower crane load-carrying dolly of the disconnected rope of capable band anti roll device.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of tower crane load-carrying dolly with disconnected rope anti roll device, it is by vehicle frame, roller, cross member of frame, assembly pulley, draw gear and anti roll device constitute, four jiaos of vehicle frame are separately installed with roller, assembly pulley is housed on the cross member of frame, the cross member of frame rear and front end of assembly pulley one side is equipped with draw gear and anti roll device successively, it is characterized in that: described anti roll device is by the safety flashboard, pin, clump weight, ear plate base, bearing pin constitutes, ear plate base is welded on cross member of frame, safe flashboard is installed on the ear plate base by bearing pin, the termination of safe flashboard one end is welded with pin, and the weld of safe flashboard and pin is equipped with clump weight.
The utility model beneficial effect compared with prior art is:
On the tower crane load-carrying dolly of the disconnected rope of this band anti roll device safe flashboard and pin are installed, when the luffing wire cable rupture, pin then loses and supports and drive safe flashboard tipped upright under the effect of clump weight, and safe flashboard is subjected to from behind the resistance of the horizontal web member in jib bottom side and stop to slip row.When having solved existing tower crane amplitude variation steel rope and disconnected rope occurring, the load-carrying dolly is at inertia and hang and slip row under the effect of thing gravity forward, causes load-carrying dolly integral body to come off and causes the problem of industrial accident.The utility model modern design, simple in structure, be specially adapted to tower crane and install and use.
Description of drawings:
Accompanying drawing is the structural representation of the tower crane load-carrying dolly of the disconnected rope of band anti roll device.
Among the figure: 1, vehicle frame, 2, roller, 3, cross member of frame, 4, assembly pulley, 5, draw gear, 6, safe flashboard, 7, pin, 8, clump weight, 9, ear plate base, 10, bearing pin, 11, the luffing steel rope.
The specific embodiment:
The tower crane load-carrying dolly of the disconnected rope of this band anti roll device is made of vehicle frame 1, roller 2, cross member of frame 3, assembly pulley 4, draw gear 5 and anti roll device, four jiaos of vehicle frame 1 are separately installed with roller 2, are used for the load-carrying dolly and seesaw along the brachium direction of jib for tower crane; On the cross member of frame 3 of load-carrying dolly assembly pulley 4 is housed, is used to install hoisting wirerope.Cross member of frame 3 rear and front ends of assembly pulley 4 one sides are equipped with the fixedly draw gear 5 and the anti roll device of luffing steel rope 11 successively.
Described anti roll device is made of safety flashboard 6, pin 7, clump weight 8, ear plate base 9, bearing pin 10, ear plate base 9 is welded on cross member of frame 3, safe flashboard 6 is installed on the ear plate base 9 by bearing pin 10, one end termination of safe flashboard 6 is welded with pin 7, and safe flashboard 6 is equipped with clump weight 8 with the weld of pin 7.
Under the normal condition, pin 7 is in the top of luffing steel rope 11, utilizes the tensile force of luffing steel rope 11 to give 7 one supporting power of pin, makes safe flashboard 6 and pin 7 and luffing steel rope 11 and vehicle frame 1 remain on a horizontal surface.Under abnomal condition, in case luffing steel rope 11 ruptures, the supporting power that pin 7 is subjected to disappears, simultaneously under the action of gravity of clump weight 8, one end of the safe flashboard 6 of pin 7 drives is sagging, and the other end upwarps, and the tipped upright and the vehicle frame 1 that make safe flashboard 6 do 90 ° are vertical configuration.6 on safe flashboard is subjected to stopping of the horizontal web member in jib bottom side, goes thereby prevent the load-carrying dolly to slip, and then has guaranteed production safety.The utility model modern design, simple in structure, be specially adapted to tower crane and install and use.
