Description

A kind of moving with rake plough car is elected to be the vertical column expanding formula hoisting crane in orientation already

Affiliated technical field

The utility model relates to a kind of hoisting and hanging mechanical equipment, is that a kind of column has the frame of joining of telescopic lifting function harrowing the hoisting crane of ploughing on the car body.

Background technology

At present, under the evil time condition of China northeast, Xinjiang Oilfield mining area, forest zone winter subzero 50 degree Celsius, 70 percent lifting transport operation is arranged by manpower and simple apparatus, because hoisting crane the weak point here of common fixed, rail type, truck mounted, train formula is: constant bearing is arranged, fixed line or track are arranged, and lubricated being in entirely of hydraulic pressure, compressed-air controlled parts freeze astringent or styptic treatment for spontaneous sweating state, is difficult to normally start and operate.

Summary of the invention

The utility model provide a kind of column have the telescopic lifting function join frame on rake plough car body hoisting crane, the column of hoisting crane contracts and falls the tailheaviness reduction, the hoisting crane base is joined frame on rake plough body car, take out rake plough car behind the selected operation orientation, the fixed crane base, stretch and rise column, lift transport operation.

The technical scheme that the utility model adopted is: the detent that is provided with and harrows the profiling of plough car body below the base of hoisting crane, be provided with the bolt leg around the base, order is equipped with lower prop above the base, center pillar, upper prop and spiral arm suspender, one cover worm and gear transmission is installed above the lower prop external diameter, the tapped bore inward turning of worm gear is being plugged in a leading screw, with leading screw affixed side by side in the same way a feed rod, at leading screw, change on the adapter plate of feed rod upper end and be inserted with tack collision block or arrow collision block, above the center pillar external diameter with each is fixing the identical dish of structure above the upper prop external diameter, every dish is provided with the location gap, the location articulated a kind of butt of opening position mechanism, butt mechanism is by articulated slab, anchor, bump pawl, pawl pin, the spring pin, spring is formed, the transmission in the hoisting crane, rotate, the antifreeze lubricant of lubricated employing that slides.

Structural principle of the present utility model and operation procedure are:

Elder generation's constant bearing: hoisting crane is with after the selected operator of rake plough car body, screws off the bolt leg around the base, props up base, after rake plough car body is deviate from profiling groove base under, takes out rake plough car, falls base and adjusts and fix.

Stretch again and go up post: plug-in mounting tack collision block on the adapter plate of leading screw, feed rod upper end, center pillar is propped up the last pivotally attached butt mechanism of dish to be unloaded, abdicate the location gap, forward drive worm and gear transmission, leading screw, feed rod rise, the tack collision block rises and passes the location gap that center pillar props up dish, push up upper prop and prop up dish pivotally attached butt mechanism, driving the top upper prop rises, upper prop rises to behind the desired location and between the center pillar and locks, reverse drive worm and gear transmission, leading screw, feed rod decline return, the butt mechanism that center pillar is propped up on the dish loads onto, and stretches to rise for center pillar and prepares.

Stretch again and rise center pillar: forward drive worm and gear transmission, leading screw, feed rod rise, the tack collision block drives and pushes up center pillar and prop up the butt mechanism that has resetted on the dish, driving the top center pillar rises, the upper prop of raise-position locking rises synchronously, and center pillar rises to behind the desired location and between the lower prop and locks, reverse drive worm and gear transmission, leading screw, feed rod decline return, hoisting crane are in the strong attitude of the operation of stretching rise.

After contract and fall column: on the adapter plate of leading screw, feed rod upper end, change and insert the arrow collision block, repeat positive and negative direction and drive the worm and gear transmission, leading screw, feed rod repeat lifting, during rising, when the arrow of arrow collision block rushes open the butt pawl, arrow is lived in cat's paw's interlock, decline pulling along with the arrow collision block, center pillar, the upper prop return that descends step by step screws off the bolt leg around the hoisting crane base then, props up base, send into rake plough car, align the profiling detent under the base, fall base and embed groove, hoisting crane is joined frame on rake plough car body.

The beneficial effects of the utility model are: under the evil time condition of ultralow temperature, the column of hoisting crane contracts and falls tailheaviness and fully reduce, join frame again on the rake plough body, can on frozen soil, weeds, freely move and be elected to be the industry orientation, especially to the selected convenience that provides in the orientation, original place of material, hoisting crane has adopted antifreeze lubricant, overcome common mechanical in the winter lubricated take place freeze astringent or styptic treatment for spontaneous sweating shortcoming.
