Abstract
The invention relates to a slips mechanism for a trenchless pipe pushing machine. The mechanism comprises a clamping device body capable of being opened or closed; a circular hole through which a pipeline can be mounted is formed in the center of the clamping device in a closed state; a plurality of slips which are uniformly distributed along the circumference direction of the circular hole are mounted on the clamping device body. The mechanism is characterized in that the slips are movably mounted in the clamping device; clamping oil cylinders are arranged on the rear surface of the slips; one of the ends of the clamping oil cylinders is connected with the clamping device body, and while the other one of the ends of the clamping oil cylinder is connected with the rear parts of the slips; the slips can be driven by the clamping oil cylinders to radially telescopically move along the circular hole; the clamping surfaces of the slips are of a circular arc shape which is adapted to that of the peripheral surface of the pipeline, and anti-skid layers are fixedly combined with the clamping surfaces. The mechanism is reasonable in structure and convenient to use; the phenomenon of slipping between the slips and the pipeline can be effectively prevented, and thus the outer surface of the protection pipe can be prevented from being damaged.
Description
Technical field
The present invention relates to the special-purpose member for clamping pipe on no-dig technique ejector sleeve machine, specifically a kind of no-dig technique ejector sleeve machine slip mechanism, belongs to technical field of engineering machinery.
Background technology
In technical field of engineering machinery, during the work of ejector sleeve machine, need pipeline to clamp, at this moment just need to use slip mechanism, slips, as a critical component, plays very important effect.When slip mechanism clamping pipeline, requirement can not damage the surface of pipeline (pipeline especially with corrosion-inhibiting coating), requires relative displacement to occur during clamping pipe simultaneously.For meeting this requirement, specially treated will be carried out in slips surface, makes it anti-skiddingly can either can ensure again that pipe surface does not sustain damage.Current processing mode arranges layer of polyurethane on slips surface, but still there is easy skidding in actual use, and in conjunction with insecure between layer of polyurethane and slips table, easily come off.
summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of no-dig technique ejector sleeve machine slip mechanism, it is rational in infrastructure, easy to use, can effectively prevent from occurring skidding between slips and pipeline, again can protective conduit external surface injury-free.
According to technical scheme provided by the invention: no-dig technique ejector sleeve machine slip mechanism, comprise the holder body that can open or enclose, enclose in the holder body of state and be formed centrally a circular duct loaded for pipeline, holder body is provided with multiple slips uniform along circular duct circumferencial direction, it is characterized in that: described slips is movably arranged in holder body, the back side of each slips is provided with clamping oil cylinder, described clamping oil cylinder one end is connected with holder body, the clamping oil cylinder other end is connected with slips back, slips can move along the radial expansion in circular duct under clamping hydraulic oil cylinder driving, the clamping face shape of described slips is the circular arc of fitting mutually with pipeline outer surface shape, secure bond skid resistant course on clamping face.
As a further improvement on the present invention, described slips comprises arc plate, the inner surface of described arc plate is as the clamping face of slips, described skid resistant course secure bond is on arc plate inner face, the back of arc plate is connected with two pieces of location-plates, be fixed with outer gusset between location-plate and the arc plate back side, connected by vertical rib plate between two pieces of location-plates.
As a further improvement on the present invention, the material of described skid resistant course is rubber, and vulcanization of rubber secure bond is on the clamping face of slips.
compared with prior art, tool has the following advantages in the present invention:
(1) in the present invention, the chucking power of slips to pipeline comes from the radial thrust of clamping oil cylinder, and fixing is more firm, and frictional force is larger, and the clamping face shape of slips and pipeline outer surface shape suitable, friction area is larger, and be not easy to slide, clamping effect is better.
(2) in the present invention slips clamping face on secure bond have skid resistant course, on the one hand rubber antiskid layer increases the frictional force to pipeline; Adopt sulfurization technology secure bond between rubber antiskid layer and slips on the other hand, adhesion is stronger; Rubber antiskid layer also can provide protection by pipe surface in addition, ensures that pipeline external surface does not sustain damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of slips in Fig. 1.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1 and Figure 2, no-dig technique ejector sleeve machine slip mechanism in embodiment forms primarily of holder body 1, slips 2 and clamping oil cylinder 3, described holder body 1 can be opened or enclose, holder body 1 is opened to install on pipeline 4, enclose in the holder body 1 of state and be formed centrally a circular duct, pipeline 4 is contained in this circular duct; Described holder body 1 is installed with multiple slips 2 uniform along circular duct circumferencial direction, described slips 2 is movably arranged in holder body 1, clamping oil cylinder 3 is provided with at the back side of each slips 2, described clamping oil cylinder 3 one end is connected with holder body 1, clamping oil cylinder 3 other end is connected with slips 2 back, and slips 2 can move along the radial expansion in circular duct under clamping oil cylinder 3 drives; The clamping face shape of described slips 2 is the circular arc of fitting mutually with pipeline 4 outer surface shape, secure bond skid resistant course 5 on clamping face.In the embodiment of the present invention, the material of described skid resistant course 5 is rubber, and vulcanization of rubber secure bond is on the clamping face of slips 2.
As shown in Figure 2, in the embodiment of the present invention, described slips 2 is the entirety be welded primarily of arc plate 6, outer gusset 7, location-plate 8 and vertical rib plate 9, the inner surface of described arc plate 6 is as the clamping face of slips 2, described skid resistant course 5 secure bond is on arc plate 6 inner face, the back of arc plate 6 is welded to connect two pieces of location-plates 8, is welded with between outer gusset 7, two pieces of location-plates 8 and is connected by vertical rib plate 9 between location-plate 8 and arc plate 6 back side.
During embody rule, slip mechanism installs to after on pipeline 4, and the piston rod of clamping oil cylinder 3 stretches out, and promote slips 2 and radially-inwardly move, the clamping face of slips 2 holds pipeline 4 tightly.According to the needs of construction operating mode, pipeline 4 can move together along with whole clamper, if clamp not strongly solid, easily loosen and occur skidding, will make to occur relative displacement between pipeline 4 and slips 2, because slips 2 clamping face of the present invention is provided with rubber antiskid layer 5, so both increase the frictional force between pipeline 4 thus avoided the generation of skidding, the external surface that can not damage pipeline 4 in clamping can have been ensured again.
