Abstract
The utility model relates to a counterweight loading and unloading mechanism for the crane, comprising a rotating platform, a left lifting cylinder, a right lifting cylinder. A proximity switch and a sensing block matching with each other are respectively positioned on the rotating platform and the car frame. The left lifting cylinder and the right lifting cylinder are respectively positioned on two sides of the rotating platform, and the piston rods of the left lifting cylinder and the right lifting cylinder is arranged downwards. The tops of the piston rods are respectively provided with a ring-shaped clamping block, and the clamping groove on the counterweight are connected with the ring-shaped clamping blocks in a cooperated manner. The utility model relates to a counterweight loading and unloading mechanism for the full ground crane, and the utility model has the advantages of simple and compact structure, proper layout and high automatization degree and wide applicable scope.
Description
Technical field
The utility model is mainly concerned with the hoisting crane field, refers in particular to a kind of hoisting crane counterweight handing device.
Background technology
Increase along with the wheel crane tonnage, the weight of corresponding counterweight has also increased many, and along with increasing of its operating mode, cooresponding counterweight is also different under different operating modes, owing to the qualification of chassis to allowable load, counterweight is compelled to do into moving counterweight, is not with counterweight when promptly driving a vehicle, and presses required installation during work.Certainly the loading and unloading of the existing counterweight of historical facts or anecdotes (promptly must other vehicle or lifting device assist, wheel crane self can load and unload counterweight), in practical operation, seem especially important for saving time and cost.But at present at home, the counterweight handing device on the outer big-and-middle-sized tonnage hoisting crane, the ubiquity complex structure has designed the mechanical pin device in mechanism, and degree of automation is low, the not high shortcoming of system reliability.
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provide a kind of simple and compact for structure, rationally distributed, degree of automation is high, applied widely, the hoisting crane counterweight handing device that can be fit to the lifting of full ground.
For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of hoisting crane counterweight handing device, it is characterized in that: it comprise turntable, left lift cylinder, right lift cylinder and be installed on respectively cooperatively interact on turntable and the vehicle frame near switch and sensor block, left side lift cylinder and right lift cylinder are installed on the both sides of turntable respectively, the piston rod of left side lift cylinder and right lift cylinder arranges down and is respectively equipped with the ring-type fixture block in the top of piston rod that the draw-in groove and the ring-type fixture block that are opened on the counterweight are connected.
Compared with prior art, advantage of the present utility model just is: adopt hoisting crane of the present utility model counterweight handing device, can make full use of the advantage of full ground hoisting crane vehicle body in handling process, make up and promote convenient and swift, easily be automated, reduce operator's labour intensity.Therefore, the utility model be a kind of safe, reliable, easy operating, low cost of manufacture, manipulation process time short, load and unload hoisting crane counterweight handing device efficiently.

The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As depicted in figs. 1 and 2, hoisting crane of the present utility model counterweight handing device, it comprise turntable 1, left lift cylinder 2, right lift cylinder 3 and be installed on respectively cooperatively interact on turntable 1 and the vehicle frame near switch 7 and sensor block 8, left side lift cylinder 2 and right lift cylinder 3 are installed on the both sides of turntable 1 respectively, the piston rod of left side lift cylinder 2 and right lift cylinder 3 arranges down and is respectively equipped with ring-type fixture block 5 in the top of piston rod that the draw-in groove 6 that is opened on the counterweight 4 is connected with ring-type fixture block 5.Principle of work: counterweight installation method of the present utility model is, accomplishes fluently supporting leg when hoisting crane is in place, after turntable 1 can turn round, just can carry out the installation of counterweight 4.Hoisting crane is by self lifting appliance, by specifying the brachium and the elevation angle, required counterweight 4 is hung on the counterweight bearing of relevant position on the vehicle frame, turntable 1 turning anticlockwise then, make turntable 1 afterbody that is provided with the counterweight handing device forward counterweight 4 tops to, when turntable 1 center and vehicle frame line of centers angle are in 5 °, what be positioned at turntable 1 the place ahead is subjected to 8 one of them triggering of two sensor blocks to signal of system's transmission near switch 7, system is with being about to rotary braking, after again piston rod being stretched out, carefully return back to turntable 1 line of centers and vehicle frame central lines, being subjected in the sensor block 8 another near switch 7 this moment triggers to system and transmits a signal, system is immediately again with rotary braking, at this moment, ring-type fixture block 5 on a left side lift cylinder 2 and the right lift cylinder 3 has snapped onto in the draw-in groove 6 on the counterweight 3, operate left lift cylinder 2 and 3 liftings of right lift cylinder, thereby driving counterweight 4 liftings puts in place, the back system pressure that puts in place is pinned by hydraulic lock, for preventing to let out in the oil cylinder, the radial deformation of left lift cylinder 2 and right lift cylinder 3 is strict controlled in 0.1%.When unloading counterweight 4, otherwise as long as with top process.
