Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the movable overturning clamp of the present invention comprises a clamping head and a clamping rod 3, wherein the clamping head comprises a clamping portion 1 and a connecting portion 4, a bayonet 7 for clamping an overturning member is provided on the clamping portion 1, a hinge hole 5 is provided on the connecting portion 4, a corresponding hinge hole 5 is provided on the clamping rod 3, a hinge shaft 6 is inserted in the hinge hole 5 of the connecting portion 4 and the clamping rod 3, and the clamping rod 3 is hinged to the connecting portion 4 of the clamping head through the hinge shaft 6; the chuck is provided with a stop block 2, the clamping rod 3 is correspondingly provided with a stop part 9, and the stop block 2 and the stop part 9 are matched with each other to limit the rotation direction of the chuck and the clamping rod 3.
Due to the interaction of the stop block 2 and the stop block 2, the chuck and the clamping rod 3 can only rotate in one direction, and the clamping rod 3 can only rotate in a clockwise direction relative to the chuck and cannot rotate in a counterclockwise direction by taking the example of fig. 1 as an example. As shown in fig. 3, when using the movable overturning clamp, an operator holds the clamping rod 3 by hand, and clamps the bayonet 7 of the clamping head clamping part 1 into the steel member 8, and can arrange a handle on the clamping rod 3 for convenient use, and when clamping, the operator pays attention to that the stress surface of the clamp faces upwards, that is, when the steel member 8 is overturned forcibly, the clamping head and the clamping rod 3 do not rotate relatively under the limitation of the stop structure. The steel member 8 can be turned by lifting the clamping rod 3 with force, and the turning is labor-saving due to the lever action. As shown in FIG. 4, after the steel member 8 overturns over the critical point of gravity, the steel member can be automatically and quickly overturned and fall under the action of gravity, the chuck continues to rotate along with the steel member 8, the operator still holds the clamping rod 3, and the clamping rod 3 can rotate clockwise relative to the chuck, so that the chuck can not influence the clamping rod 3 in the hand of the operator along with the rotation of the steel member 8, and thus, the safety threat to the operator can not be caused.
Wherein, the chuck can adopt current all kinds of chucks, also can adopt the preparation of thick steel plate opening, and clamping bar 3 can adopt steel pipe, billet preparation, and the pin joint is great at upset in-process atress, and in order to guarantee articulated stability, connecting portion 4 of chuck includes the connecting plate of two parallels, the hinged end of clamping bar 3 is located between two connecting plates, and articulated shaft 6 passes two connecting plates and middle clamping bar 3 makes connecting plate and clamping bar 3 articulated mutually.
The stop block 2 of the chuck and the stop portion 9 of the clamping rod 3 are oppositely arranged, and have various specific shapes and positions, for example, the stop block 2 can be connected to two connecting plates to seal the rotation direction of one side of the clamping rod 3. In the embodiment shown in fig. 1 to 4, the stop block 2 is located between the two connecting plates, and the stop portion 9 is the clamping rod 3 extending from the ends of the two connecting plates. I.e. the end of the clamping bar 3 interacts with the stop block 2 in front of it to achieve the limit. The strength of the stop block 2 needs to be guaranteed, the chuck and the clamping rod 3 are well matched in a rotating angle, the stop block 2 is of a triangular structure with an oblique groove, the end portion of the clamping rod 3 is correspondingly provided with the oblique groove serving as a stop portion 9, and the oblique groove of the stop block 2 is matched with the oblique groove of the stop portion 9 to limit the rotating directions of the chuck and the clamping rod 3. The stop block 2 and the stop part 9 are convenient to manufacture, have high strength and are not easy to clamp when relative rotation is needed. The angle of the oblique groove is preferably 30-60 degrees.
Like fig. 1 ~ 4 do the utility model discloses an preferred embodiment, whole anchor clamps overall length 900mm for make things convenient for the operator to use, mostly use 10 ~ 20mm thick steel sheet preparation
First, a steel plate with a clamping part 1 of 100mm multiplied by 90mm multiplied by 40mm is provided with a mouth with a depth of 50mm and a width of 30mm at one end. For catching the grooves of the steel member 8 in operation.
Secondly, the clamping part 1, the stop block 2 (a triangular steel plate with the size of 40mm multiplied by 30mm multiplied by 20 mm) and the connecting part 4 (two steel plates with the size of 40mm multiplied by 30mm multiplied by 20 mm) form a clamping head.
And thirdly, drilling a hinge hole 5 with the diameter phi of 10mm at one end of the connecting part 4. Then, one end of a clamping rod 3 (a steel bar with the diameter of 800mm multiplied by 30mm multiplied by 20 mm) is sawn into an angle of 55 degrees, a hinge hole 5 with the diameter of 10mm is drilled in the middle from the sharp angle to the position of 60mm, and the other end is a holding handle.
Fourthly, the chuck is connected with the clamping rod 3 by a bolt or a pin bolt with the diameter of 10mm multiplied by 60mm to form a movable clamp.
