Abstract

The utility model relates to a connector which is arranged between a piston of concrete conveying pump and a cylinder rod of an oil cylinder, particularly a floating type connector. The utility model is characterized in that a floating sphere is clamped at the middle of a floating disc and a fixing end, the floating disc is installed in a spherical surface cavity of a floating end, and the adjustment of swing amount solves the problem that the centre line of the oil cylinder and the centre line of a concrete cylinder are misaligned to generate the misalignment of the centre line of the piston and the centre line of a concrete cylinder, avoids the fast abrasion and damage of the piston generated by the misalignment and the phenomenon of the sprain and the damage of the inner wall of the oil cylinder and the piston in the oil cylinder, ensures the normal and safe use of a device and enhances service life.

Description

Floating type joiner

The utility model relates to piston and the operating cylinder cylinder rod coupling in a kind of concrete pump mud cylinder, especially a kind of floating type joiner.

Piston in the present various concrete pump mud cylinder, with connecting of operating cylinder cylinder bar all are rigidity, when the mud cylinder does not overlap with the operating cylinder center line, be contained in piston on the operating cylinder cylinder bar and move in the mud cylinder and just can be subjected to the effect of radial force, at this moment will produce two kinds of consequences: a kind of is wearing and tearing (scuffing of cylinder bore) between oil cylinder piston and the oil cylinder casing wall in the main operating cylinder; Another kind is that piston wearing and tearing are too early scrapped in the mud cylinder.These two kinds of consequences cause main operating cylinder to damage and increase the replacing frequency of piston in the mud cylinder, cause very big economic loss on the one hand, have a strong impact on the utilization efficiency and the effect of equipment on the other hand.And the oil cylinder center line not overlap with mud cylinder center line be the phenomenon that often has, this defective just be the original structure joiner can't overcome.

The purpose of this utility model provides a kind of floating type joiner, the various adverse consequencess that it can prevent from the work to be produced effectively, and making rigid joint is adjustable connection, guarantees that device security uses.

The utility model purpose is achieved in that it only needs on the basis of original equipment, is connected a floating type joiner between piston and oil cylinder cylinder bar, so structure is simple especially, and realizes synchronous adjustment easily.Floating type joiner is by floating end, and floating disc, connecting cap, spin, cushion pad, fixed end, Cock screw constitute.Floating end connects with piston, and fixed end connects with oil cylinder cylinder bar by the special-purpose clip that connects.Changed original overall structure, adjusted the piston center line and do not overlap, and realized moving radially, realized rotatablely moving, realized that thus piston moves with respect to the three-dimensional of operating cylinder cylinder bar in the mud cylinder by floating disc by floating end with mud cylinder center line; Adopt spin as the guide way that moves radially, make piston in the mud cylinder around even contact, eliminate the suffered radial force of oil cylinder cylinder bar, the protection oil cylinder alleviates piston wear.

The utility model compared with prior art has following advantage:

1, the utility model is moved radially floating end owing to adopt spin as floating conductor, makes piston even contact in the mud cylinder, guarantees that oil cylinder cylinder bar is not subjected to the effect of radial force, and wall is exempted from scuffing of cylinder bore;

2, the utility model adopts floating disc as the conductor along the axis rotation, and piston integral body is moved with mud cylinder concentric line in the mud cylinder, reduces friction, and reduces resistance, reduces power loss;

3, the utility model is simple in structure, and is easy to manufacture, is easy to promotion and application, and low to mud cylinder and the requirement of oil cylinder installation precision, need not adjust.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is an overall structure schematic representation of the present utility model.

Below in conjunction with accompanying drawing 1 detailed description according to the utility model proposes the details and the working condition of concrete device.

As shown in Figure 1.Floating type joiner is made of floating end 1, floating disc 2, connecting cap 3, spin 4, cushion pad 5, fixed end 6, Cock screw 7.Floating end 1 connects with piston, and fixed end 6 connects with oil cylinder cylinder bar by the special-purpose clip that connects.The floating disc 2 of dribbling face is contained in the sphere chamber of floating end 1, guarantees that the sphere of floating end 1 contacts with the sphere of floating disc 2, adjusts oscillating quantity.On floating disc 2 and fixed end 6, process respectively and the corresponding rounded channels of spin 4 spheres, and spin 4 is clamped in the middle of floating disc 2 and the fixed end 6 in the rounded channels, as the guide way that moves radially, this moment is relative with two faces of rounded channels, two rounded channels is vertical mutually, cushion pad 5 is placed in connecting cap 3 chambeies, reduces friction and impact.Again connecting cap 3 and floating end 1 are passed through scyewed joint,, adopt Cock screw 7 to fix for preventing thread looseness and whole location.Fixed end 6 is contained in the connecting cap 3, and fixed end 6 radially keeps certain clearance with connecting cap 3, and the gap is 2-5mm.

Embodiment:

When the mud cylinder is parallel lines with the center line of oil cylinder (not overlapping), will spin 4 be rolled, thereby floating end 1 is moved radially by piston action in 1 one radial forces of floating end, reach job requirement; When mud cylinder center line intersects with the oil cylinder center line, will be by piston action rotating force on floating end 1, this power makes floating end 1 around floating disc 2 rotations, reaches job requirement; When mud cylinder center line becomes different surface beeline with the oil cylinder center line, more than two kinds of power act on simultaneously, reach job requirement, at this moment piston center line and mud cylinder central lines.
