Abstract

The utility model provides a concrete pump S pipe valve, includes S valve tip, S valve main aspects, S valve tip has primary shaft bearing (2), the setting is in first bearing (3) in primary shaft bearing (2), lie in first sealing washer (12) and second sealing washer (13) in first bearing (3) both ends outside respectively, be located the first fender ring (7) and first dust ring (6) in second sealing washer (13) outside in proper order, the cavity that enclose primary shaft bearing (2), first bearing (3), first sealing washer (12) and second sealing washer (13) is through first lubricated oil circuit (1) and lubricating system intercommunication, the cavity that first fender ring (7) and first dust ring (6) encloses passes through second lubricated oil circuit (4) and lubricating system intercommunication. The bearing is lubricated through lubricated oil circuit fuel feeding, and the pressure between bearing seal circle and dust ring is oily for in outside impurity such as concrete are hard to get into the bearing, the life of equipment has been prolonged.

Description

A kind of Concrete Pump with S pipe valve

Technical field

The utility model relates to concrete pump technical field, especially relates to a kind of Concrete Pump with S pipe valve.

Background technique

S pipe valve is widely used in concrete pumping equipment, is mainly used to the distribution realizing material.S pipe valve is the critical component of concrete pump, it is positioned at hopper and connects conveying cylinder and delivery pipe, its working principle is swung fast by S pipe left and right in the hopper filling concrete materials, docks in turn, thus realize concrete continus convergence with two concrete cylinders.S pipe valve is the mechanism coordinating each component actuation, thus directly affects the usability of concrete pump, and directly affects the global design of concrete pump.

In prior art, S pipe valve has bearing support, and its axle is connected with bearing support by bearing, and seal ring is used respectively in the two ends of bearing, baffle ring, wiper seal, prevents outside concrete from entering in bearing.Bearing is by lubricating oil path feed lubrication, but baffle ring or between seal ring and dust ring, do not have lubricating oil path fuel feeding to lubricate it, cause this part easy to wear, concrete outside after wearing and tearing easily enters, and makes the working life of equipment shorter.

Model utility content

In order to overcome the defect of prior art, the purpose of this utility model is: provide a kind of Concrete Pump with S pipe valve, have longer working life.

In order to solve the problems of the technologies described above, the Concrete Pump with S pipe valve that the utility model provides, comprises S valve small end, the large end of S valve, and described S valve small end has clutch shaft bearing seat; Be arranged on the clutch shaft bearing in described clutch shaft bearing seat; Lay respectively at the first seal ring outside clutch shaft bearing two ends and the second seal ring; Be positioned at the first baffle ring outside the second seal ring and the first dust ring successively; The cavity that described clutch shaft bearing seat, clutch shaft bearing, the first seal ring and the second seal ring surround is communicated with lubrication system by the first lubricating oil path, and the cavity that described first baffle ring and the first dust ring surround is communicated with lubrication system by the second lubricating oil path.

As improvement opportunity scheme, the Concrete Pump with S pipe valve that the utility model provides, the large end of described S valve has the second bearing support; Be arranged on the second bearing in described second bearing support; Lay respectively at the 3rd seal ring outside the second bearing two ends and the 4th seal ring; Be positioned at the second dust ring outside the 3rd seal ring; The cavity that described second bearing support, the second bearing, the 3rd seal ring and the 4th seal ring surround is communicated with lubrication system by the 3rd lubricating oil path, and the cavity that described 3rd seal ring and the second dust ring surround is communicated with lubrication system by the 4th lubricating oil path.

The beneficial effects of the utility model: the technological scheme that the utility model provides, bearing is by lubricating oil path feed lubrication, between bearing sealed ring and dust ring, be provided with lubricating oil path fuel feeding to lubricate it, pressure oil between bearing sealed ring and dust ring, make the impurity such as outside concrete be difficult to enter in bearing, extend the working life of equipment.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the structural representation of embodiment's Concrete Pump with S pipe valve;

Fig. 2 is the structural representation of the small end of embodiment's Concrete Pump with S pipe valve;

Fig. 3 is the structural representation of the large end of embodiment's Concrete Pump with S pipe valve.

Embodiment

Concrete Pump with S pipe valve as shown in Figure 1 to Figure 3, comprises S valve small end, the large end of S valve, and S valve small end has clutch shaft bearing seat 2; Be arranged on the clutch shaft bearing 3 in clutch shaft bearing seat 2; Lay respectively at the first seal ring 12 and the second seal ring 13 outside clutch shaft bearing 3 two ends; Be positioned at the first baffle ring 7 and the first dust ring 6 outside the second seal ring 13 successively; Clutch shaft bearing seat 2, clutch shaft bearing 3, first seal ring 12 are communicated with lubrication system by the first lubricating oil path 1 with the cavity that the second seal ring 13 surrounds, and the cavity that the first baffle ring 7 and the first dust ring 6 surround is communicated with lubrication system by the second lubricating oil path 4; The large end of S valve has the second bearing support 9; Be arranged on the second bearing 8 in the second bearing support 9; Lay respectively at the 3rd seal ring 10 outside the second bearing 8 two ends and the 4th seal ring 5; Be positioned at the second dust ring 11 outside the 3rd seal ring 10; Second bearing support 9, second bearing 8, the 3rd seal ring 10 are communicated with lubrication system by the 3rd lubricating oil path with the cavity that the 4th seal ring 5 surrounds, and the cavity that the 3rd seal ring 10 and the second dust ring 11 surround is communicated with lubrication system by the 4th lubricating oil path.

In working procedure, clutch shaft bearing 3, second bearing 8 is respectively by lubricating oil path feed lubrication, lubricating oil path fuel feeding is provided with between the first baffle ring 7 and the first dust ring 6, between the 3rd seal ring 10 and the second dust ring 11, keep on the one hand lubricating it, the pressure oil existed between them on the other hand, make the impurity such as outside concrete be difficult to enter in bearing, thus extend the working life of equipment.

Obviously, the utility model is not limited to above preferred implementation, in the spirit that also can limit in the utility model claim and specification, carry out conversion and the improvement of various ways, can same technical problem be solved, and obtain the technique effect of expection, therefore not repeat.Those of ordinary skill in the art can from content disclosed in the utility model directly or all schemes associated, as long as within the spirit limited in claim, also belong to protection domain of the present utility model.
