Abstract
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
The invention belongs to mechanical engineering technical field, disclose a kind of lifting trolley device.
Background technology
Lifting trolley device is one of key equipment of revolving furnace sublance.Sublance is fixed on the lift cart, does up-and-down movement by its drive.Lift cart must guarantee sublance operation up and down nimbly and freely, and static organ is adjusted two uniform tension in order in the steel cable at any time; Simultaneously enough safe reliabilities to be arranged, prevent from sublance to be crashed in the smelting furnace, produce serious accident because of the steel rope breaking of lifting truck.Can lifting trolley device safely, work reliably, will directly have influence on the service efficiency of sublance.
The lift cart that uses all is the anti-fall device of voussoir friction-type at present, and owing to reasons such as foozle, transportation distortion, the condition that produces frictional force can not effectively be set up usually.In case fall the rifle accident, gently then oxygen lance damages, and is heavy then smash equipment, fatal accident occurs; Difficult treatment needs more renewal of facing renewal, from new adjusting play etc. afterwards; Lift cart steel cable static organ adopts second lever abroad, and wherein one-level is a set square shape, and rod member is many, complex structure; Two steel cables make lifting wheel and static organ rod member strained condition complexity to swing on one side in the equilibrium process; Equal amount is little.
Summary of the invention
The object of the present invention is to provide a kind of lifting trolley device.This device mainly is made up of static organ and anti-fall device, static organ adopts the lever form, anti-fall device adopts ratchet piece form is installed on the track, the lever of static organ is connected with vehicle frame with fork arm by bearing pin, fork arm is connected with the support bar of anti-fall device by bearing pin, and the support bar middle part is hinged on the vehicle frame with bearing pin.
The present invention realizes in the following way:
Static organ adopts the lever form, and the bearing pin of band perforate is equipped with at the lever two ends, and pull bar penetrates perforate and is connected with steel cable; Anti-fall device stops falling of dolly by ratchet on the track or groove; The structure formation that both and vehicle frame organically combine by bearing pin, hole slot.
Sublance is installed on the vehicle frame, and the steel cable lifting truck moves up and down along fluctuating orbit.Elevator is connected the lever two ends by steel cable, pull bar and is equipped with on the bearing pin with holes, and lever links to each other with vehicle frame with anti-fall device by bearing pin.Be welded with ratchet or process groove on fluctuating orbit, when the disconnected rope of lift cart fell, anti-fall device was opened automatically by ratchet or groove and is blocked, and reaches anti-fall purpose.
The static organ anti-fall device of brand new can guarantee effectively that lift cart is unlikely to crash in the smelting furnace when the unexpected fracture of steel cable.Accident generation aftertreatment accident is simple, hangs up steel cable and can recover works better automatically, at ordinary times can be non-maintaining; In works better, can protect just two steel cable stress balances, but equal amount reaches maximum in unidimensional static organ; The assembling form that both and vehicle frame organically combine makes the body construction compactness; Be in operation and guarantee two steel cable stress balances.
Description of drawings
Accompanying drawing is the synoptic diagram of lift cart.
Among the figure, part 1 is an elevator, and part 2 is a steel cable, part 3 is a pull bar, and part 4 is a track, and part 5 is a wheel one, part 6 is a wheel two, and part 7 is a lever, and part 8 is a bearing pin with holes, part 9 is a vehicle frame, and part 10 is the ratchet piece, and part 11 is a support bar, part 12 is a bearing pin one, and part 13 is a bearing pin two, and part 14 is a fork arm, part 15 is a bearing pin three, and part 16 is a spring.
Embodiment
The present invention is further described below in conjunction with accompanying drawing:
The steel cable 2 of elevator 1 is connected pull bar 3 upper ends, the lower end of pull bar 3 is plugged in bearing pin with holes 8 holes of lever 7 ends, lever 7 is connected with vehicle frame 9 with fork arm 14 by bearing pin 3 15, the top of fork arm 14 is installed with spring 16, the bottom is connected with bearing pin 2 13, fork-join has support bar 11 on the bearing pin 2 13, and support bar 11 middle parts are hinged on the vehicle frame 9 with bearing pin 1; It is by wheel 1 and wheel one 6 guiding that lift cart moves in track 4; Ratchet piece 10 is installed on the track 4.
Sublance is installed on the vehicle frame, and the steel cable lifting truck moves up and down along fluctuating orbit.During works better, elevator 1 drives the upper end that lever 7 is against the vehicle frame elongated hole, drives support bar 11 and rotates around bearing pin 1 by fork arm 14, bearing pin 2 13, and support bar 11 bottoms are narrowed, and less than two ratchet pieces, 10 spacings on the track 4, makes the dolly lifting unaffected; Lever 7 rotates around bearing pin 3 15, makes two steel cables be in symmetric position, the stressed balance that is able to, and maximum equal amount can be provided.
After the unexpected fracture of wireline, the spring elongation, promotion bearing pin 3 15, lever 7 move down with respect to vehicle frame in elongated hole, lean against the lower end of elongated hole, and open support bar 11 bottoms simultaneously, is bearing on the ratchet piece 10, thereby stops the lift cart tenesmus.
Leave groove on the track 4, be bearing on the groove after support bar 11 bottoms are opened, thereby stop the lift cart tenesmus.
This apparatus structure is simple, and is easy to manufacture, and it is little to take up room, and keeps in repair easy.Product cost reduces.The swing of 2 steel cables is equilibrated all the time in the lift cart operational process, and strained condition is stable.The anti-fall device reliable operation, be active in one's movements, accident generation aftertreatment accident is simple, hangs up steel cable and can recover works better automatically, at ordinary times can be non-maintaining.This device can be widely used in steel-making or other similar lifting trolley devices.
