Background technology
Oxygen lance lifting bogie is one of key equipment of converter oxygen gun system.The oxygen rifle is fixed on the lift cart, does up-and-down movement by its drive.Will there be enough safety coefficient the vertical position of the necessary strict guarantee oxygen rifle of lift cart simultaneously, prevents from because of the wire cable rupture of lifting truck the oxygen rifle to be crashed in the smelting furnace.Can hoisting appliance safely, work reliably, will directly have influence on the service efficiency of oxygen rifle; And in case fall the rifle accident, gently then oxygen lance damages, and is heavy then smash equipment, fatal accident occurs.
Present oxygen lance anti-fall lift cart, mainly contain double track rail chartered steamer form and the wheel bag rail form of single track, there are the following problems for it: 1) the lift cart safety dropping prevent mechanism adopts voussoir friction-type structure, can not guarantee effective foundation of frictional force, and probability of failure is bigger; 2) for the lift cart of the rail chartered steamer form of double track, its wheel is a swing-in, can not dismantle at the station place.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the lift cart that provides a kind of anti-block rifle to fall.The utility model is safe and reliable to operation, in light weight, Maintenance and Repair convenient, can effectively solve the difficult problem of oxygen lance anti-fall, avoids weighing down the rifle accident and takes place, and can realize the mounting or dismounting of dolly at the station place.
The utility model is realized by such scheme, the lift cart that a kind of anti-block rifle falls, it comprises vehicle frame, be installed in the wheel one of vehicle frame both sides and the elongated hole that wheel two, two ends place the vehicle frame both sides transverse axis and with the friction tight tackleblock of transverse axis; It is characterized in that: screw thread fork arm and support bar are set in vehicle frame, are provided with anti-fall in orbit.
The vehicle frame of above-mentioned dolly has corresponding hole and is used to install wheel one, wheel two for the skeleton construction of welding, side about the vehicle frame and front-back.
For convenience install and remove, keep in repair at the station place, the utility model has adopted outward opening structure that wheel is fixed on the vehicle frame; Wheel one, wheel two respectively have 4; Wheel one, wheel two lay respectively at vehicle frame two outsides up and down; After passing corresponding aperture on the vehicle frame respectively, the axle of wheel one, wheel two wheel is fixed on the vehicle frame with nut; Wherein wheel one is vertical mutually with the axle of wheel two.
The utility model is the wheel bag rail form of double track, this kind structure kept wheel bag rail advantage---producing apparatus is less demanding, precision guarantees easily, install, debug easy, wheel one is responsible for the location, front and back of vehicle frame, wheel two be responsible for vehicle frames about the location, the front and back of controlling dolly respectively tumble and about tumble, guarantee that the oxygen rifle is in vertical position.
In order to prevent the tenesmus of wire cable rupture lift cart, the utility model has adopted Retchet gear type from resetting safety dropping prevent mechanism, and screw thread fork arm, support bar are set in vehicle frame, welds the ratchet piece in orbit.
The through hole that described screw thread fork arm passes the vehicle frame top is arranged in the vehicle frame; This screw thread fork arm middle and lower part has the hole, and the hole that transverse axis passes on the screw thread fork arm places the axle two ends in the elongated hole that the vehicle frame both sides leave along the vertical direction; Screw thread fork arm top is equipped with spring; One end of support bar is connected with screw thread fork arm lower end by bearing pin one, and the other end cooperates with vehicle frame by bearing pin two; The ratchet piece spacing is arranged is welded on two siding tracks.
Described screw thread fork arm top is thin cylinder with the level, and there is screw thread the upper end of cylinder; Screw thread fork arm bottom is flat rectangular parallelepiped; Flat rectangular parallelepiped upper end has manhole and cooperates with transverse axis; Flat rectangular parallelepiped lower end cooperates with support bar, connects by bearing pin one between the two.
The through hole that the vehicle frame top is passed on described screw thread fork arm top cooperates with nut, and nut is suspended on the screw thread fork arm in the vehicle frame, and the screw thread fork arm can move up and down in vehicle frame along the through hole of vehicle frame top.
Described support bar has two, intersects to place; The upper end of two support bars links together by bearing pin one and screw thread fork arm lower end, and the lower end of two support bars cooperates with vehicle frame respectively by bearing pin two; The lower end of two support bars contacts with two siding tracks respectively.
The ratchet piece, is symmetrically distributed on two siding tracks every one of determining deviation welding in the track total length.
Spring is installed in screw thread fork arm upper step place.
The hole that described transverse axis passes on the described screw thread fork arm places two ends in the elongated hole that the vehicle frame both sides leave along the vertical direction, and can move up and down in vehicle frame along this hole.
Under the standard state, wireline is wrapped on the tackleblock, reel pulling rope hoisting tackleblock, it is up with respect to vehicle frame to drive transverse axis, screw thread fork arm, bearing pin one, the while compression spring, and make support bar around bearing pin two rotations, and two support bar lower ends narrow relatively, and it is up in track to make lift cart drive oxygen lance; Otherwise it is descending in track that lift cart drives oxygen lance.When wire cable rupture took place, the lifting force on the rope disappeared, the spring elongation, and gravity promotes the screw thread fork arm and moves down, and the support bar lower end is opened rapidly, is supported on the ratchet piece, stops the lift cart tenesmus.During the processing accident as long as wireline put on connect, hoisting cable, mechanism just automatically resets, and recovers normal.
In order to prevent the lift cart tenesmus, the utility model can also a plurality of grooves be set in orbit or shrinkage pool stops falling of dolly.When dolly dropped, they sup-port stoped the lift cart tenesmus on groove or shrinkage pool.
The utility model has adopted outward opening double track wheel bag rail form and Retchet gear type from resetting safety dropping prevent mechanism, and working accuracy guarantees easily, installs, debugging is easy, convenient in the dismounting of station place, maintenance, and effectively stops and resolving the generation that rope weighs down the rifle accident.Whole apparatus structure is simple, and is in light weight, and cost is low, safe and reliable.
