Description
Technical field
The utility model relates to a kind of tensioning equipment of carbon cloth, is specifically related to a kind of carbon cloth stretch-draw clamp mechanism.
Background technology
Carbon fiber is the high new material of a kind of intensity, and in recent years, the method that uses carbon fiber tape to paste is carried out structural strengthening, be widely used among structural strengthening, but carbon fiber tape is applied to prestressing force, or an emerging technology.Carbon fiber tape being applied to prestressed method both at home and abroad is at present mainly to adopt fixture anchor stretch-draw carbon cloth method, but in the time applying prestressing force, irony fixture contacts with soft carbon cloth, and when tightening fixture, carbon cloth is easily impaired.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of carbon cloth stretch-draw clamp mechanism, uses this clamp mechanism can ensure that clamping force can effectively avoid again not damaging carbon cloth in the time applying prestressing force.
The technical solution of the utility model is: a kind of carbon cloth stretch-draw clamp mechanism, it is characterized in that mainly being formed by hold-down mechanism, connector and clamp mechanism, described hold-down mechanism comprises handle, rotating shaft and eccentric wheel, wherein eccentric wheel is fixed in rotating shaft, this rotating shaft is articulated with in the circular hole on connector top, and is fixed with handle in a side of rotating shaft; Described clamp mechanism comprises top board and lower platen, wherein lower platen is fixed on the downside of connector, and be provided with the arc groove of axial perforation on the top of lower platen, the both sides of described top board are respectively equipped with projection, this projection is fixed in the central channel of connector, and projection and central channel are slidably matched, in the central channel below projection, be respectively equipped with spring, the bottom of described top board is provided with the arc convex matching with lower platen top arc groove.
Eccentric block in hold-down mechanism described in the utility model is two, is fixed on symmetrically in rotating shaft.
The utility model simplicity of design, easy to operate, be easy to install, in engineering construction process, speed of application is fast, has improved operating efficiency.
Brief description of the drawings

Detailed description of the invention
Describe by reference to the accompanying drawings embodiment in detail.A kind of carbon cloth stretch-draw clamp mechanism, mainly formed by hold-down mechanism 1, connector 2 and clamp mechanism 3, described hold-down mechanism 1 comprises handle 4, rotating shaft 5 and eccentric wheel 6, wherein eccentric wheel 6 is fixed in rotating shaft 5, this rotating shaft 5 is articulated with in the circular hole on connector 2 tops, and is fixed with handle 4 in a side of rotating shaft 5; Described clamp mechanism 3 comprises top board 7 and lower platen 8, wherein lower platen 8 is fixed on the downside of connector 2, and be provided with the arc groove of axial perforation on the top of lower platen 8, the both sides of described top board 7 are respectively equipped with projection 9, this projection 9 is fixed in the central channel 10 of connector 2, and projection 9 is slidably matched with central channel 10, in central channel 10 below projection 9, be respectively equipped with spring 11, the bottom of described top board 7 is provided with the arc convex matching with lower platen 8 top arc grooves.
Eccentric block 6 in hold-down mechanism 1 described in the utility model is two, be fixed on symmetrically in rotating shaft 5, adopt two-wheel hold-down mechanism, impel clamping force more even, adopt eccentric wheel hold-down mechanism to there is auto-lock function, do not need to increase extras, easy to use, time saving and energy saving, simple in structure, cheap and clamping force is larger.
Operating principle of the present utility model is: when compression, turning handle, drives rotating shaft and eccentric wheel to rotate, along with the increase of rotational angle, eccentric wheel external profile diameter strengthens gradually, thereby compression top board, top board is along the central channel down sliding on connector, along with the increase of clamping force, realize and clamp carbon cloth, arrive after certain position, this clamp mechanism can realize self-locking, keeps clamping force.
Claims (2)
1. a carbon cloth stretch-draw clamp mechanism, it is characterized in that mainly being formed by hold-down mechanism, connector and clamp mechanism, described hold-down mechanism comprises handle, rotating shaft and eccentric wheel, wherein eccentric wheel is fixed in rotating shaft, this rotating shaft is articulated with in the circular hole on connector top, and is fixed with handle in a side of rotating shaft; Described clamp mechanism comprises top board and lower platen, wherein lower platen is fixed on the downside of connector, and be provided with the arc groove of axial perforation on the top of lower platen, the both sides of described top board are respectively equipped with projection, this projection is fixed in the central channel of connector, and projection and central channel are slidably matched, in the central channel below projection, be respectively equipped with spring, the bottom of described top board is provided with the arc convex matching with lower platen top arc groove.
