Background technique
Concrete pumping mechanism generally includes conveying cylinder, concrete piston, water tank and master cylinder, and concrete piston is arranged in conveying cylinder, and it is connected with the piston rod of master cylinder, and water tank is then between conveying cylinder and master cylinder.When pumping work, master cylinder drives the to-and-fro motion in conveying cylinder of concrete piston, completes suction and discharge action.
In prior art, the concrete piston that pumping mechanism uses is generally by adpting flange, bolt and main oil cylinder piston bar rigid joint, but after reality processing, assembling, master cylinder is difficult to keep coaxial with conveying cylinder, in order to can normally work, just need to improve machining accuracy.Therefore will ensure very high perpendicularity requirement, these parts machining craft precisions will be made to become large, if slightly deviation, during work, concrete piston will produce larger vibrations, and concrete piston is shortened working life.
In order to solve the problem, the solution of current employing is generally between concrete piston and piston rod, increase an independently floating junction device, one " concrete piston connector of concrete pump " such as disclosed in CN2937555Y, is namely provided with a floating connection bar between concrete piston and main oil cylinder piston bar.But the scheme of this increase independent floating connection set not only structure is comparatively complicated, and the length of water tank and independently link length have conflict, namely water tank length in fact can be shorter than the total length of concrete piston and link, means and moves back the little operation inconvenience of piston rear space.
On the other hand, existing pumping mechanism, the commutation action of piston and move back piston action when changing concrete piston, all needing to realize by arranging a locating oil cylinder, needing a single supporting spacing loop, complex structure.
Model utility content
Technical problem to be solved in the utility model is to provide the concrete pumping mechanism of a kind of structure simply with floating connection concrete piston connection device, and its concrete piston and main oil cylinder piston bar adopt simple to be floating typely connected.
Another technical problem to be solved in the utility model is to provide a kind of concrete pumping mechanism that can realize commutating and moving back the band floating connection concrete piston connection device of piston action without the need to locating oil cylinder, and it can simplify the internal structure of an organization.
For solving the problems of the technologies described above, technical solution of the present utility model is:
With a concrete pumping mechanism for floating connection concrete piston connection device, comprise conveying cylinder, concrete piston, water tank and master cylinder, concrete piston is arranged in conveying cylinder, and the piston rod of master cylinder is connected with concrete piston, and water tank is between conveying cylinder and master cylinder; Described piston rod and concrete piston adopt bulb to be connected, and namely the end of this piston rod is one-body molded bulb, and this concrete piston is provided with semi-spherical grooves, and this bulb is assemblied in this semi-spherical grooves, then is clamped by bulb by a flange plate.
Preferably, described flange plate is made up of the two panels flange plate of symmetrical separated type, and two panels flange plate is bolted on concrete piston.
Preferably, one end that described flange plate contacts with bulb is with spherical shape, and this spherical shape matches with the sphere of bulb.
Preferably, the cylinder body of described master cylinder being provided with three proximity switches, is proximity switch and cylinder bottom portion proximity switch on rear side of proximity switch on front side of cylinder, cylinder respectively.
After adopting such scheme, due to the floating type connecting mode that the utility model adopts, that the one end be connected with concrete piston at main oil cylinder piston bar is machined directly to bulb, at concrete piston joint processing ball groove, sphere also can be processed in flange plate one end, avoid like this being rigidly connected, concrete piston can be made to keep the friction of very low limit with conveying cylinder inboard wall of cylinder block, effectively raising concrete piston working life; And directly processing bulb can reduce structure complexity with ball groove, minimizing cost, and can reduce the total length of concrete piston and piston rod, can not be formed and the conflicting of water tank length, more convenient in operation.
In addition, the utility model installs three proximity switches at three positions of master cylinder, in order to alternative locating oil cylinder, can simplify the internal structure of an organization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
What the utility model disclosed is a kind of concrete pumping mechanism with floating connection concrete piston connection device, as shown in Figure 1, is preferred embodiment of the present utility model.Described concrete pumping mechanism comprises conveying cylinder 1, concrete piston 2, water tank 3 and master cylinder 4, wherein: concrete piston 2 is arranged in conveying cylinder 1, the piston rod 41 of master cylinder 4 is connected with concrete piston 2, master cylinder 4 drives concrete piston 2 reciprocal in conveying cylinder 1 when pumping work, 3, water tank is between conveying cylinder 1 and master cylinder 4.Key of the present utility model is: described piston rod 41 adopts bulb to be connected with concrete piston 2, namely described piston rod 41 end is one-body molded bulb 411, described concrete piston 2 is provided with semi-spherical grooves 21, this bulb 411 is assemblied in this semi-spherical grooves 21, by a flange plate 5, bulb 411 is clamped again, to ensure that piston rod 41 is not separated with concrete piston 2.
Further, described can be made up of the two panels flange plate of symmetrical separated type for the flange plate 5 clamped, and two panels flange plate is connected on concrete piston 2 by bolt 6, and bulb 411 is not separated with concrete piston 2.
More specifically, one end that described flange plate 5 contacts with bulb 411 is with spherical shape, and this shape matches with the sphere of bulb 411, and bulb 411 can effectively be rotated.
Another crucial part of the present utility model is: the cylinder body of described master cylinder 4 is provided with three proximity switches, is proximity switch 72 and cylinder bottom portion proximity switch 73 on rear side of proximity switch 71, cylinder on front side of cylinder respectively.
