Abstract
The utility model relates to a connection structure of an S-shaped pipe valve transmission axle of a concrete pump. A carbon structure steel axle sleeve is inlaid and sleeved at one end of the prior alloy steel transmission axle through the utility model, the outer circumference of the axle sleeve is positioned and welded with a connection sleeve arranged on a valve seat, and the axle sleeve is interferingly matched with the transmission axle. The utility model has the advantages that the structure simple and reasonable, the structural strength is high, the service life is long, the anti-fatigue strength of the welding of the S-shaped pipe valve transmission axle and the valve seat can be effectively enhanced, the service life of the S-shaped pipe valve transmission axle is effectively prolonged, and the utility model is suitable for industrialized production, and can be used in combination of S-shaped pipe valves with various models.
Description
Technical field
The utility model relates to the concrete construction mechanical field, is meant a kind of linkage structure of Concrete Pump with S pipe valve transmission shaft especially.
Background technique
Concrete pump is by the concrete a kind of concrete construction machinery of pipeline force feed, at present, concrete pump generally adopts the structure of S pipe valve to realize the distribution of material, its working principle is: by swing fast about the S pipe is in filling the hopper of concrete materials, push cylinder with two concrete in turn and dock, thereby realize concrete continuous conveying; At present, the S pipe valve transmission shaft of all S pipe valve concrete pumps and S pipe valve body all adopt the solder joint structure on the market.The general employing of S pipe valve transmission shaft has the high-quality alloy steel manufacturing of high strength, high impact toughness, high-fatigue strength.But the Alloy Constructional Steel welding performance is relatively poor, and it is very sensitive to the welding thermal stress, the fatigue strength of its welding part declines to a great extent after welding, owing to require swing fast about it during the work of S pipe valve, therefore, the alternating action of tensile stress, pressure stress and shearing stress that its transmission shaft and valve body welding part are subjected to changing repeatedly causes S pipe valve transmission shaft and valve body welding part early fracture to occur, influence the stability of equipment work, bring inconvenience for operation, maintenance.
Summary of the invention
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple and reasonable, structural strength is high, the linkage structure of the Concrete Pump with S pipe valve transmission shaft of long service life.
The utility model is to adopt following proposal to realize: at existing alloyed steel transmission shaft one end edge cover one structural carbon steel axle sleeve, sleeve outer circle week and the joint sleeve welding location of being located on the valve seat are interference fit between described axle sleeve and the transmission shaft.
Further improvement of the utility model is: be provided with at least one connecting key between described axle sleeve and transmission shaft, in order to transferring power.
Another improvement of the present utility model is: be provided with a delineation position boss in described transmission shaft end and be complementary with the location concave station of being located at sleeve end, realize axially locating.
The utility model is owing to adopt the said structure form, on the one hand, utilize the interference fit between axle sleeve and the transmission shaft, make axle sleeve become as a whole with transmission shaft, be provided with between axle sleeve and transmission shaft particularly that at least one key is connected and in the transmission shaft end one delineation position boss is set is complementary with the location concave station of being located at sleeve end, further guaranteed the axially locating between transmission shaft and the axle sleeve, make transmission shaft and axle sleeve realize seamless connectivity, in conjunction with tightr, during work, guarantee that each parts is at high load, can bear violent swing impact under the operating conditions of HI high impact and not have the play phenomenon, effectively guaranteed the reliability of transmission shaft work, simultaneously, transmission shaft adopts key to be connected with axle sleeve, has improved the mode of moment of torsion that transmission shaft bears, bearing moment of torsion by the single section in past changes into a plurality of sections and bears moment of torsion jointly, reduce the moment of torsion that single section bore, promoted the S pipe valve and born moment of torsion and impact resistance, prolonged the working life of S pipe valve; On the other hand, because the welding performance excellence of structural carbon steel, insensitive to the welding thermal stress, welding line structure intensity height, be welded as a whole with the joint sleeve that is provided with on the valve seat, the overall construction intensity height has been eliminated the influence of welding heat stress Alloy Constructional Steel transmission shaft, can increase substantially the fatigue resistance of S pipe valve transmission shaft.In sum: the utility model is simple and reasonable, structural strength is high, long service life, can effectively improve the fatigue resistance of S pipe valve transmission shaft and valve seat weld seam, effectively prolong the working life of S pipe valve transmission shaft, be suitable for industrialized production, can use with the S pipe valve deploying cover of various models.
