Description
Technical field
The present invention relates to a kind of pushing tow pipes, more particularly to a kind of axial pushing tow spigot-and-socket pipe.
Background technique
Existing spheroidal graphite cast-iron pile pipe is to meet pile pipe installation and construction, requirement with face by the conical surface of bell and spigot,
Its interface form is simple, is easily installed, and bellmouth and socket are the conical surface, and tamping force passes through mutual cooperation when carrying out pile pipe construction
Bellmouth the conical surface and socket the conical surface transmitting and auxiliary directional.
The said goods currently on the market are mainly based on small dimension, even if being small dimension product, since it is for holding
The required precision of the socket conical surface is more stringent, and processing cost is also relatively high.
Spheroidal graphite cast-iron pile pipe product has preferable mechanics and antiseptic property, but prior art spheroidal graphite cast-iron pile pipe then faces
Several problems are as specification increases first, and taper precision is difficult to guarantee；Second, if taper is done it is small, socket be easy it is super slotting, lead
It causes socket to be inserted beyond bellmouth and enters straight pipe, so that socket destroys；Third can guarantee socket not if taper is done greatly
It is super slotting, but for common centrifugal casting technique, success rate is lower.
Summary of the invention
Present invention purpose is directed to the shortcomings that prior art spheroidal graphite cast-iron pile pipe, it may be assumed that only small dimension product, and according to
Tamping force transmitting and auxiliary directional when carrying out pile pipe construction by cone match, conical surface required precision is high, and casting is difficult to ensure, if plus

Specific embodiment
As shown in Figure 1, axial pushing tow bell-and-spigot pipe of the invention, connects, direction is beaten vertically or at a certain angle by root socket joint
Enter in stratum.
As depicted in figs. 1 and 2, one end of axial pushing tow bell-and-spigot pipe of the invention is bellmouth, and the other end is socket, an axis
It is inserted into the socket of pushing tow bell-and-spigot pipe in the bellmouth of another axial pushing tow bell-and-spigot pipe, socket includes: in receptacle wall 3 and socket
End face 4, receptacle wall 3 are circle, and bellmouth includes: bellmouth inner wall 1 and bellmouth inner face 2, the cross-sectional circumferential of bellmouth inner wall 1 by
The small arc 6 of the big arc 5 of bellmouth inner wall and bellmouth inner wall intersected together forms, and the center of circle of the small arc 6 of bellmouth inner wall and axial pushing tow are held
The axle center of intubation is identical, and the radius of the small arc 6 of bellmouth inner wall is greater than the radius of receptacle wall 3, and the center of circle of the big arc 5 of bellmouth inner wall is located at
On the crosspoint 7 of the parallel lines in the cambered surface of the small arc 6 of bellmouth inner wall and axial pushing tow bell-and-spigot pipe axle center, the arc of the big arc 5 of bellmouth inner wall
The minimum range in face to axial pushing tow bell-and-spigot pipe axle center is less than the radius of the small arc 6 of bellmouth inner wall, the big arc 5 of bellmouth inner wall in bellmouth
The quantity of the small arc 6 of wall is equal and is respectively not less than 2, such as in Fig. 2, the big arc 5 of bellmouth inner wall and the quantity of the small arc 6 of bellmouth inner wall are
3, the equal length of each arc of the big arc 5 of bellmouth inner wall, the equal length of each arc of the small arc 6 of bellmouth inner wall, bellmouth inner wall
Big arc 5 distance intervals such as in the cross circular section circumferential direction of bellmouth inner wall 1 are distributed, cross of the big arc 6 of bellmouth inner wall in bellmouth inner wall 1
Equidistant intervals are distributed on cross-sectional periphery direction, are inserted into another axial pushing tow socket joint in the socket of an axial pushing tow bell-and-spigot pipe
When the bellmouth of pipe, matching between socket and bellmouth is combined into local interference fit, and socket end face 4 contacts to pass with bellmouth inner face 2
Pass jacking force.
The axial pushing tow principle of axial pushing tow bell-and-spigot pipe of the invention: as shown in Figure 1, the socket for the bell-and-spigot pipe that will be installed
It is inserted into the bellmouth of the bell-and-spigot pipe installed, since bellmouth inner wall is by 6 liang of the big arc 5 of bellmouth inner wall and the small arc of bellmouth inner wall
The cambered surface in section different-diameter or axle center composition, so that in view of the socket in the case of manufacturing tolerance also can be with bellmouth inner wall at least shape
It is interference fitted at two sections, during this is interference fitted in socket insertion bellmouth, so that socket cross sectional shape changes, when slotting
After mouthful being fully inserted into bellmouth, socket inner face 4 will be in contact with bellmouth inner face 2, at this point, bellmouth inner wall and receptacle wall are matched
Conjunction and the cooperation of bell and spigot end face, ensure that the stability in axial pushing tow direction and the reliability of power transmission, realize stability and high efficiency
Axial incremental launching construction.
Above description is explanation of the invention, is not intended to limit the invention, and limited range of the present invention is referring to right
It is required that the present invention can make any type of modification without prejudice to spirit of the invention.
