Description
Technical field
The utility model relates to the special-purpose member for clamping pipe on no-dig technique ejector sleeve machine, and 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 purpose of this utility model is to overcome the deficiencies in the prior art; there is provided 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 outer surface injury-free.
Technical scheme according to the utility model provides: 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 further improvement of the utility model, 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 further improvement of the utility model, 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 the utility model:
(1) in the utility model, 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 utility model 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.

Fig. 1 is the structural representation of the utility model embodiment.
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 utility model is described in further detail.
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 utility model embodiment, 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 utility model embodiment, 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 utility model is provided with rubber antiskid layer 5, so both increase the frictional force between pipeline 4 thus avoided the generation of skidding, the outer surface that can not damage pipeline 4 in clamping can have been ensured again.
