Specific embodiment
The utility model is described in detail below in conjunction with attached drawing:
A kind of CFG stake machine with modified bridge piece 5 as shown in Figure 1, including rack 1, hoisting system 2, feed
System 3 and construction system 4, rack 1 is arranged by adjustable support leg on ground and L-shaped, also logical in the side of L-type rack 1
It crosses bolt and is fixed with reinforcing rod.Hoisting system 2 includes the hoist engine in rack 1, and hoist engine passes through the steel across pulley blocks
Rope realizes the lifting to construction system.Construction system 4 is connected to rack 1 by the way that hoisting system 2 is liftable.Feeding system 3 is logical
It crosses feed pipe 31 to connect with construction system 4, construction system 4 includes the power device 41 for being connected to hoisting system 2, end with brill
First 43 drilling rod 42, the removable lower section for being fixed in power device 41 in 42 upper end of drilling rod, bridge piece 5 and drilling rod core pipe 44, drilling rod
Core pipe 44 is arranged in drilling rod 42 and the upper end is stretched out from drilling rod 42 upwards to connect above-mentioned bridge piece 45；Bridge piece 5
For steel pipe, including bend loss 51 and straight pipe 52, the sealing of 52 both ends of straight pipe is fixed in 44 middle section of drilling rod core pipe, bend loss 51 1
End is shaped in the side of straight pipe 52, because the mixture of pile rises to oblique entrance from compression at bridge piece 5
Bend loss 51 enters drilling rod core pipe 44 into straight pipe 52, and stress, force direction variation are fast, complicated, is integrally formed so that even
Connecing bend pipe 5 is a stable entirety, improves the job stability and anti-leak result when construction.51 other end of bend loss is set
There is the interconnecting piece 511 connecting with feed pipe 31.
In the present embodiment, feeding system includes sequentially connected concrete pump 32, chute 33 and being stirred backward by feed pipe 31
Machine 34 is mixed, blender 34 is arranged position and is higher than 32 horizontal position of concrete pump, i.e. chute 33 connects blender 34 with an inclination angle
With concrete pump 32, after the completion of the process of stock blend carries out in blender 34, mixture can under gravity directly
It is fallen in concrete pump 32 by chute 33, equipment and the energy needed for reducing raw material transport save construction cost.Feed pipe 31
Including the high tensile flexible pipe 311 being connect with bend loss 51 and the rigid pipe 312 being connect with concrete pump 32, high tensile flexible pipe 311
It is tightly connected with rigid pipe 312, rigid pipe 312 has many advantages, such as intensity height, wear-resistant, by rigid pipe 312 that concrete is defeated
It send to the pipe fitting loss that can be reduced at rack in mixture conveying, reduces maintenance cost and replacement cost, while in rigid pipe
Mixture is delivered to construction system 4 by the high tensile flexible pipe 311 being tightly connected by 312 end, and characteristic flexible is convenient for
Connection installation, while its intensity guarantees that it is hardly damaged.
As shown in Figure 2,3, in the present embodiment, 51 axis line track of bend loss is in half elliptic.Compared to CFG traditional in Fig. 2
Stake machine bridge piece, having with 44 junction of drilling rod core pipe is in downward curve shape rather than horizontal connection, thus in mixture
Straight pipe 52 can be dropped downward under gravity after ascending into bend loss 51 and eventually enters into drilling rod core pipe 44, therefore not
It will appear in traditional bridge piece in horizontal segment because the siltation deposition of mixture occurs in the problems such as insufficient pressure, interruption, guarantee to supply
Construction quality has been effectively ensured the problems such as avoiding because of generation broken pile under feeding, undergauge in the stabilization of doses and feeding speed.
Meanwhile the ellipse short shaft radius of 51 axis of bend loss is 30cm, which is the reasonable curvature obtained by empirical formula
Radius, on the one hand manufacture easy to process, is on the other hand convenient for passing through for mixture.
In the present embodiment, 52 both ends of straight pipe are equipped with sealing flange 521.So that straight pipe 52 passes through with drilling rod core pipe 44
Sealing flange 521 realizes the face connection stablized, sealed.Meanwhile 511 end of interconnecting piece is also sealing flange 521, for
Connecting tube 31 realizes effective sealed connection, while connecting with other pipe fittings and all being realized by sealing flange 521 so that connecting bending
The manufacturing of pipe 5 more standardizes and simplicity.
In the present embodiment, 52 internal-and external diameter of straight pipe is equal with 44 internal-and external diameter of drilling rod core pipe.After mounting, straight pipe 52 and brill
The internal diameter of bar core pipe 44 is identical, the change of conveying capacity will not occurs because of the variation of caliber in mixture conveying, guarantee construction
Stablize.
It is equipped with inspection hole 53 in the present embodiment, at the top of bend loss 51 and seals the removable inspection cover being installed in inspection hole 53
54。
In the present embodiment, distance-transmission pressure gauge 55 is equipped with by the way that screw thread is removable in inspection cover 54.It can by distance-transmission pressure gauge 55
Even if easily to monitor the pressure state in bridge piece 5 consequently facilitating the progress of construction personnel adjusts maintenance accordingly.
Above embodiments are only described preferred embodiments of the present invention, not to the structure of the utility model
Think and range is defined, without departing from the design concept of the present utility model, ordinary people in the field is practical new to this
The all variations and modifications that the technical solution of type is made each fall within the protection scope of the utility model, the utility model request
The technology contents of protection, are all described in the claims.
