Abstract
The utility model relates to a variable-angle concrete pump pipe joint which belongs to a device for conveying fluid. The utility model comprises an inner ball cover body and an outer ball cover body which are connected with each other, and both ends of the utility model are respectively provided with a clamping groove connected with a concrete pump pipe. After the inner ball cover body is connected with the outer ball cover body, the inner ball cover body, a regulating ring and a meshing cover together form a cavity body, wherein the cross-sectional shape of the cavity body is accordance with the cross-sectional shape of the outer ball cover body, and the outer ball cover body is arranged in the cavity body to be connected with the inner ball cover body; after the outer ball cover body is arranged in the cavity body, the remaining space is used as an oil cavity which is provided with an oil filling hole. The inner ball cover body which is respectively connected with pump pipes rotates freely in the outer ball cover body so as to reach any angle needed by construction, and the construction trouble of pipe replacement and the hidden trouble are avoided. The utility model has the advantages of convenient operation, high safety, time saving and labor saving, and the oil cavity and the oil filling hole are arranged to have favorable lubricating action.
Description
One, technical field
The utility model relates to a kind of rotary concrete pump pipe joint, belongs to the feedway of fluid.
Two, background technique
In building engineering construction, adopt the towed concrete pump car to carry out concreting at present more.Existing concrete pump pipe joint all is to decide the angle pump pipe union, in construction as change pump line direction, that must remove that original angle changes another specification decides the angle pipe, need frequent translation-angle in the construction, so change very trouble, one will be equipped with the pump pipe union of plurality of specifications, not only to lose time and change joint, also can cause the concrete in the pipe to run off.Its two, concrete pump line internal pressure is bigger during replace tubes, easily whitewashing is hurted sb.'s feelings.Its three, former pump pipe union is to decide angle, and required angle is indefinite in the construction, requires upper and lower, left and right to swing, and can not satisfy the construction needs.
The design's joint also can be applicable to the concrete automotive pump.Original automotive pump front end adopts rubber hose, can satisfy the needs of swing, but flexible pipe is long, and the pipe internal pressure is big, and flexible pipe rocks greatly in the construction, will hold up the operator of pipe to drag down easily.Moreover, cause the accident owing to use the long folding pipe that easily causes of flexible pipe to make the flexible pipe explosion.Rubber is easily aging, changes duty, makes cost up.
Three, summary of the invention
To be solved in the utility modelly be exactly above-mentioned technical problem and a kind of variable-angle concrete pump pipe joint that makes the concrete pump line change direction arbitrarily is provided.The technological scheme that is adopted is as follows: this variable-angle concrete pump pipe joint comprises interconnective endosphere body, ectosphere body, the draw-in groove that is connected with the concrete pump line is respectively established at its two ends, two endosphere bodies form cavity with adjusting to enclose, mesh after cover is connected, the sectional shape of the sectional shape of cavity and ectosphere body adapts, the ectosphere body places and forms in the cavity and being connected of endosphere body, the ectosphere body places that remaining space is an oil pocket behind the cavity, and oil pocket is provided with oil hole.
The other end that above-mentioned outer spheroid overlaps relative draw-in groove is provided with rubber seal, and the endosphere body is provided with rubber seal.
Ectosphere body any rotation in endosphere body of the utility model by connecting pump line respectively can reach the needed any angle of construction, avoids the construction trouble and the potential safety hazard of replace tubes, and be easy to use, safe and reliable, time saving and energy saving; The setting of oil pocket, oil hole can play good lubrication.
Four, description of drawings
Accompanying drawing is the utility model structural representation; Wherein (9), cavity (10) are overlapped in endosphere body (1), endosphere body (2), rubber seal (3), oil hole (4), ectosphere body (5), draw-in groove (6), bolt (7), adjustment circle (8), engagement.
Five, embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, as shown in drawings: this rotary concrete pump pipe joint, the draw-in groove (6) that is connected with the concrete pump line is respectively established at two ends, can snap in pump line during use, the outer sectional shape that one end is established outer spheroid cover (5) the other end of draw-in groove (6) is a cydariform, endosphere body (1), endosphere body (2) connects the back and adjusts circle (8) by bolt (7), engagement cover (9) forms cavity (10) jointly, the sectional shape of the sectional shape of cavity (10) and ectosphere body (5) adapts, ectosphere body (5) places in the cavity (10) and forms and endosphere body (1), the connection of endosphere body (2), it is oil pocket that ectosphere body (5) places cavity (10) back remaining space, oil pocket is provided with oil hole (4), outer spheroid cover (4) the other end of draw-in groove (6) relatively is provided with rubber seal (3), and endosphere body (1) is provided with rubber seal (3).
Claims (3)
1, a kind of variable-angle concrete pump pipe joint, comprise interconnective endosphere body, the ectosphere body, the draw-in groove that is connected with the concrete pump line is respectively established at its two ends, it is characterized in that: endosphere body (1), endosphere body (2), adjust circle (8), engagement cover (9) connects the back and forms cavity (10), the sectional shape of the sectional shape of cavity (10) and ectosphere body (5) adapts, ectosphere body (5) places in the cavity (10) and forms and endosphere body (1), the connection of endosphere body (2), it is oil pocket that ectosphere body (5) places cavity (10) back remaining space, and oil pocket is provided with oil hole (4).
2, variable-angle concrete pump pipe joint according to claim 1 is characterized in that: outer spheroid cover (4) the other end of draw-in groove (6) relatively is provided with rubber seal (3).
3, variable-angle concrete pump pipe joint according to claim 1, it is characterized in that: endosphere body (1) is provided with rubber seal (3).
