Description
Technical field
The utility model relates to the fixture that is embedded in sleeve pipe wherein when a kind of track plate is made in advance.
Background technology
Existing cover pipe fixing device, all be to adopt the sleeve pipe bolt, be that the sleeve pipe bolt passes bed die from track plate bed die below, spin with the service sleeve that is positioned at the bed die top again, this just need dig foundation ditch in advance below bed die, the staff must install bolt from the foundation ditch that is arranged in the bed die below, install very inconveniently like this, and cause construction cost very high, simultaneously, must below track plate bed die, the sleeve pipe bolt removed earlier before the demoulding of track plate, after the demoulding of track plate, reinstall the sleeve pipe bolt again, make operation loaded down with trivial details, repeat, cause production efficiency low.
The utility model content
Based on the defective of prior art, the technical problems to be solved in the utility model is: provide a kind of being convenient to install, be convenient to the demoulding, operation is simplified greatly, the adjustable anchor that production efficiency is high.
The technical solution of the utility model is: a kind of adjustable anchor, comprise the stepped locating shaft that is loaded on the track plate bed die, the lower end of locating shaft is passed track plate bed die and is fixed by nut, locating shaft shaft part near plane on the track plate bed die is up-small and down-big cone structure, the upper end screw thread of locating shaft is connected with the upper end and has the swelling cover of tightening structure, be socketed with the adjustment packing ring on the locating shaft in the swelling cover between the shaft shoulder of side-lower and locating shaft, this swelling cover lower end is provided with at least one longitudinal opening groove.
The described structure of tightening is that swelling cover periphery adopts six sides or tetragonal, and six sides or cubic angle be fillet, and the inwall of fillet and service sleeve is suitable.Be convenient to locating shaft is tightened on the track plate bed die.The periphery of clamp nut adopts this fillet structure, is the better fit of being convenient to service sleeve, helps improving stability of the present utility model.
The outside, termination of the longitudinal opening groove of described swelling cover is provided with the annular knurl that increases frictional force.The longitudinal opening groove of swelling cover lower end has three or four.
The described swelling cover outside is socketed with service sleeve, and the service sleeve lower end is near plane on the track plate bed die, and seals by sealing ring between the contact-making surface on plane on service sleeve and the track plate bed die.Plane and service sleeve contact position are provided with the annular recess that extends along service sleeve lower surface circumferencial direction on the described track plate bed die, and described sealing ring is loaded in the annular recess.
The beneficial effects of the utility model are: easy for installation, need not to remove this positioner during the demoulding, directly extract the track plate, adjustable anchor still is installed on the track plate bed die, only needs new service sleeve is socketed in that swelling puts and can realize building of next track plate; Make the production process of track plate simplify, production efficiency improves greatly.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.

The specific embodiment
Preferred embodiment
Extremely shown in Figure 9 as Fig. 1, a kind of adjustable anchor, comprise the stepped locating shaft 7 that is loaded on the track plate bed die 6, track plate bed die 6 and fixing by nut 5 is passed in the lower end of locating shaft 7, locating shaft 7 shaft parts near plane on the track plate bed die 6 are up-small and down-big cone structure 4, the upper end screw thread of locating shaft 7 is connected with swelling cover 2, the structure of tightening that 2 upper ends have tetragonal 9 is overlapped in swelling, this angle, four directions is fillet 11, fillet 11 is suitable with the inwall 12 of service sleeve 1, be socketed with on the locating shaft 7 in swelling cover 2 between the shaft shoulder 8 of side-lower and locating shaft 7 and adjust packing ring 10, this adjustment packing ring 10 can be controlled the length of swelling cover along the locating shaft backspin, effectively prevent between swelling cover lower end and service sleeve and the locating shaft stuck, in case it is stuck between swelling cover lower end and service sleeve and the locating shaft, anchor can not the demoulding, causes the track plate to damage; This swelling is overlapped 2 lower ends and is provided with four longitudinal opening groove 2-1, the outside, termination of the longitudinal opening groove 2-1 of swelling cover 2 is provided with the annular knurl 2-2 that increases frictional force, swelling is overlapped 2 outsides and is socketed with service sleeve 1, service sleeve 1 lower end is near plane on the track plate bed die 6, and seal by sealing ring 3 between the contact-making surface on plane on service sleeve 1 and the track plate bed die 6, plane and service sleeve 1 contact position are provided with the annular recess 6-1 that extends along service sleeve 1 lower surface circumferencial direction on the track plate bed die 6, and described sealing ring 3 is loaded among the annular recess 6-1.
