Abstract
The utility model discloses a kind of push-bench slip casting structure, including base（1）, outer-hexagonal bolt（2）, plain washer（3）, rubber washer（4）, outer-hexagonal bolt（2）And plain washer（3）By rubber washer（4）Fix and be covered in base（1）Top surface on；The base（1）For hollow structure, its underpart is mud entrance, after middle part and top increase for the mud pressure in slip casting passage, and the slip casting passage, can open rubber washer by top（4）Carry out slip casting.When push-bench needs to carry out slip casting operation, mud enters slip casting passage by the mud entrance of base bottom, and mud pressure increase, which can be pushed up, holds rubber washer progress slip casting, and mud plays lubrication hence into handpiece case border.
Description
Technical field
The utility model is related to a kind of push-bench slip casting structure, specifically a kind of slip casting of push-bench head jacking
Structure.
Background technology
At present, push-bench belongs to a kind of trenchless engineering machinery, by the way that by head, the laying of pipe of cement is realized in jacking forward
Work, different working conditions can produce different frictional resistance to head shell.Filling system is that push-bench is noted to outside housing
The main device of slurry, currently in long range jacking construction, the application of filling system can substantially reduce jacking resistance, so that
Improve jacking efficiency.
But, existing filling system have impact on efficiency of construction because jacking resistance is larger, while peripheral muddy water is easy
Into inside the head of push-bench, many inconvenience are brought to jacking construction, therefore urgently improve.
The content of the invention
For above-mentioned existing technical problem, the utility model provides a kind of reasonable compact conformation, reliability and construction effect
Rate is high, it is adaptable to the slip casting structure of push-bench head jacking.
To achieve the above object, the utility model provides a kind of push-bench slip casting structure, including base, outer-hexagonal spiral shell
Rubber washer is fixed and is covered on the top surface of base by bolt, plain washer, rubber washer, outer-hexagonal bolt and plain washer；It is described
Base is hollow structure, and its underpart is mud entrance, and middle part and top are the mud pressure in slip casting passage, and the slip casting passage
After increase, rubber washer can be opened by top and carry out slip casting.After said structure, because rubber washer has one-way flow
Function, after slip casting is stopped, can effectively preventing the mud of handpiece case from entering inside head, reliability is higher.
Further, cross slip casting support is connected with the top of the base inner wall.
Further, the rubber washer is cylindrical structural, which is provided with four slip casting holes in cross arrangement,
And four branches of four slip casting holes and above-mentioned slip casting support place correspondingly.
The utility model uses the structure of similar check valve, realizes the slip casting lubricating function of push-bench head shell, has
Effect reduces jacking resistance, improves jacking efficiency, and effectively prevent closure periphery muddy water into inside head, is applied to push pipe
Work brings higher convenience.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 top view；
Fig. 3 is the structural representation of base in the utility model；
Fig. 4 is Fig. 3 top view；
In figure：1st, base, 2, outer-hexagonal bolt, 3, plain washer, 4, rubber washer.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model push-bench includes base 1, outer-hexagonal bolt 2, plain washer with slip casting structure
Rubber washer 4 is fixed and is covered on the top surface of base 1 by the 3, rubber washer 4, outer-hexagonal bolt 2 and plain washer 3.
Wherein, as shown in figure 3, base 1 is hollow structure, its underpart is mud entrance, and middle part and top are slip casting passage.
Also, as shown in figure 4, cross slip casting support is connected with the top of the inwall of base 1.
As shown in Fig. 2 rubber washer 4 is cylindrical structural, four slip casting holes in cross arrangement are which is provided with, and
Four branches of four slip casting holes and above-mentioned slip casting support place correspondingly.
When push-bench needs to carry out slip casting operation, mud enters slip casting passage, mud pressure by the mud entrance of the bottom of base 1
Power increase, which can be pushed up, holds the progress slip casting of rubber washer 4, and mud plays lubrication hence into handpiece case border.This practicality
It is new be particularly suitable for use in long range jacking construction when the larger slip casting handling situations of jacking pressure, effectively mud can not only be noted
Enter to head shell outer ring, additionally it is possible to reduce jacking resistance, improve efficiency of construction.
