Description
Technical field
The invention belongs to automobile impact test apparatus, be specifically related to a kind of pinion and-rack self-locking rope-grippers.
Background technology
At present, the rope-grippers that adopts of domestic automobile collision experiment can be divided into fixed and two kinds of pulling types; The fixed type rope clip device begins to be fixedly connected with drag rope all the time to end from impact test, can't realize colliding the circulation of line, troublesome poeration.And at the moment of collision and the overtension of traction rope, be prone to the formation accident for fixed rope clip; Can realize collision line realization circulation for traditional pulling type rope-grippers, but its complex structure, rope clip module force also because its structure is restricted, can't further improve; In the present locking mode of understanding, the offset cam locking mode is because its simple structure can lock fast with the latching characteristics of offset cam and in various latch mechanisms, be used widely, but its coupling mechanism force is little, and reliability is not high.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, rope clip module force is big, safe and reliable pinion and-rack self-locking rope-grippers.
Realize that the technical scheme that the object of the invention adopts is: pinion and-rack self-locking rope-grippers comprises base; The bottom of base is provided with one and connects opening; One side of base upper edge pass through openings direction is provided with the hinge slide block that slides in the direction; It is watt corresponding with said pass through openings to be hinged with movable claw on the hinge slide block, and the part that on the base of establishing the hinge slide block, forms said pass through openings watt constitutes with movable claw as fixed claw watt embraces rope parts; Be positioned at the pass through openings opposite side on the base and be provided with the offset cam that cooperates with movable claw watt tooth, offset cam is provided with handle.
Occlusal surface on said fixed claw watt and the movable claw watt is equipped with tusk.
Adopt slide rail chute structure to be connected between said hinge slide block and the base.
Be provided with retracing spring between said movable claw watt and the hinge slide block.
Said base is provided with the reinforcement cover with hinge slide block and movable claw watt parcel.
Adopt the detachable type grip of said structure to have manually clamping and auto lock function in advance.Pass through openings on the bottom is used to place the cable wire of traction impact test automobile; Fixed claw watt and movable claw watt are used for cable wire is embraced folder; Rotate offset cam through handle movable claw watt is applied acting force, movable claw watt is clamped steel cable in advance, steel cable also capable of using is pullled the outside slippage of drive hinge slide block; Make offset cam watt further apply acting force, realize auto-lock function movable claw.The present invention is simple in structure, and rope clip module force is big, and is safe and reliable.
Below in conjunction with accompanying drawing the present invention is described further.

Embodiment
Embodiment 1
See Fig. 1, Fig. 2, pinion and-rack self-locking rope-grippers comprises base, and base comprises left base 9 and right base 1, left and right base 9,1 is connected integrant web joint 6; Web joint 6 is divided into upper and lower web joint 601,602; Form one between left and right base 9,1 bottom and connect opening A, be provided with the hinge slide block 7 that slides in the direction along the left base 9 of pass through openings A direction one side; Adopt dovetail slide rail chute structure 14 to be connected between hinge slide block 7 and the left base 9, left base 9 is provided with dovetail groove 14, and the bottom of hinge slide block 7 is provided with that dovetail groove 141 cooperates on dovetail slide rail 141 and the left base 9; The dovetail slide rail 141 of hinge slide block 7 is provided with spacing hole 15; It is corresponding with said pass through openings A to be hinged with movable claw watts 10 with long pin 13 on the hinge slide block 7, is provided with return torsion spring 12 between movable claw watts 10 and the hinge slide block 7; Constitute with movable claw watts 10 as fixed claw watt and embrace rope parts establishing on the left base 9 of hinge slide block 7 part that forms said pass through openings A; Be equipped with tusk 16 on the occlusal surface of fixed claw watt and movable claw watts 10, to increase interlocking to steel cable 8; Be positioned on the right base 1 of pass through openings A opposite side and be provided with and the movable claw watt offset cam that 10 teeth cooperate 2 through bearing pin 11; Be equipped with tooth 17 on offset cam 2 and the movable claw watts 10; Nearest position, the tool center of circle is provided with a platform 201 on the periphery of offset cam 2, and offset cam 2 is provided with handle 4; Between the web joint 6 of base, be provided with the reinforcement cover 5 of hinge slide block 7, strengthen cover 5 and be provided with the breach corresponding 3 with offset cam with movable claw watt 10 parcels; Lower connecting plate 602 is provided with the breach 602a corresponding with hinge slide block 7, so that hinge slide block 7 can pass in slippages, the spacing hole 15 that also is provided with dovetail slide rail 141 on spacing block set 602b and the hinge slide block 7 cooperates.
Principle of work:
In service at the vehicle impact testing line, require rope-grippers to accomplish two processes that steel cable 8 is clamped and loosens:
Clamping process: the present invention has manually clamping and auto lock function in advance in clamping process.See Fig. 1; Steel cable 8 is placed in the pass through openings A on the base, depress movable claw watts 10, make it to be meshed with offset cam 2 with tooth 17; Drive offset cam 2 rotations through handle 4 being bestowed certain moment of torsion; Because the rotation of offset cam 2 increases its lock radius gradually, simultaneously through the moving movable claw of cingulum watts 10 with hinge slide block 7 do outside sliding motion (rack-and-pinion) with clockwise rotate (hinges) thus hold steel 8 tightly, realize manually clamping in advance; In the process of outside steel cable 8 is stressed, drawing, cross gear pair and be delivered to offset cam 2 lock radius is further increased, realization auto lock function owing to will drive pawl watt 10 further outer Mobile Communication with the friction of movable claw watts 10.
The process of loosening: utilize mechanical hook-up collision handle 4 backward rotation offset cams 2, reduce lock radius rapidly, the elastic force of return torsion spring 12 opens movable claw watts 10 counterclockwise, thereby realizes loosening steel cable 8.When the platform on the periphery of offset cam 2 201 was in movable claw watt 10 mated position, movable claw watts 10 opened fully.
Hinge slide block among the present invention also can adopt the slide rail chute structure of other employing to be connected with left base, and as shown in the figure, the hinge slide block has the slide rail of T shape head, is clipped in the top and the bottom 901 of base 9, between 902 in the chute.
