Problems solved by technology
[0003] The lifting trolleys currently used are all wedge friction-type anti-drop devices. Due to manufacturing errors, transportation deformation, etc., the conditions for generating friction are usually not effectively established.
In the event of a gun drop accident, the oxygen blowing pipe will be damaged in the slightest, and the equipment will be smashed in severe cases, resulting in personal accidents; it is difficult to deal with it afterwards, and the friction plate needs to be replaced, and the gap should be readjusted; The stage is in the shape of a triangular plate, with many rods and complex structure; during the balancing process, the two steel ropes swing to one side, which makes the force state of the lifting wheel and the balancer rods complicated; the balance is small

Embodiment Construction
[0011] Below in conjunction with accompanying drawing, the present invention is further described:
[0012] The steel rope 2 of the winch 1 is connected to the upper end of the pull rod 3, and the lower end of the pull rod 3 is inserted into the hole pin 8 at the end of the lever 7, and the lever 7 is connected with the fork bar 14 and the vehicle frame 9 through the pin 3 15, The top of fork bar 14 is worn with spring 16, and the bottom is connected with pin two 13, and pin two 13 is fork connected with support bar 11, and the middle part of support bar 11 is hinged on the vehicle frame 9 with pin one 12; Running in 4 is guided by wheel one 5 and wheel one 6; Ratchet block 10 is installed on the track 4.
[0013] The auxiliary gun is installed on the frame, and the steel rope lifting trolley moves up and down along the lifting track. During normal operation, the hoist 1 drives the lever 7 to lean against the upper end of the elongated hole of the vehicle frame, and drives th...

The invention belongs to the technical field of mechanical engineering and discloses a lifting trolley device. The device consists of a balancer and a fall preventing device, wherein the balancer adopts a lever mode; the fall preventing device adopts a mode of arranging a ratchet block on rails; the lever of the balancer is connected with a rod jaw and a vehicle frame through pin shafts; the rod jaw is connected with a support rod of the fall preventing device through a pin shaft; and the middle part of the support rod is hinged on the vehicle frame by a pin shaft. The device is simple in structure, easy to manufacture, small in space occupation and convenient in overhaul. The product cost is reduced. During the operation of a lifting trolley, the swinging of two steel ropes are constantly balance and stable in stress state. The fall preventing device is reliable in operation and flexible in action, allows for simple accident handling after an accident happens, automatically restores to normal operation after steel rope is hanged and avoids maintenance in normal time. The device can be widely used as iron making or like lifting trolleys.
Description
technical field [0001] The invention belongs to the technical field of mechanical engineering and discloses a lifting trolley device. Background technique [0002] The lifting trolley device is one of the key equipment of the converter sub-gun. The auxiliary gun is fixed on the lifting trolley, which drives the lifting movement. The lifting trolley must ensure that the sub-gun moves up and down flexibly, and the balancer adjusts the tension of the two steel ropes at any time; at the same time, it must be safe and reliable enough to prevent the sub-gun from falling into the furnace due to the breakage of the steel rope of the lifting trolley. , resulting in major safety accidents. Whether the lifting trolley device can work safely and reliably will directly affect the use efficiency of the sub-gun. [0003] The currently used lifting trolleys are all wedge friction-type anti-drop devices. Due to manufacturing errors, transportation deformation and other reasons, the condit...
