detailed description

The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

As shown in the figure, a manual tightener for the inner ring of the mandrel of the pipe gallery anchorage according to the present invention includes an adjusting screw 1, a dial 2, a fixing plate 3 and a force transmission plate 4, and the dial 2 Set vertically, there is a "U" groove 5 under the dial 2, a handle 6 is arranged above the dial 2, a through hole 7 is arranged in the middle of the dial 2, the adjusting screw 1 passes through the through hole 7 horizontally, and the adjusting screw The left side of 1 is fixed on the shifting plate 2 through a lock nut 8, the right side of the adjusting screw 1 passes through the vertically arranged fixing plate 3, the rightmost side of the adjusting screw 1 is provided with a nut 9, and the force transmission plate 4 is arranged on the adjustment Below the screw rod 1 , the right side of the force transmission plate 4 is flexibly connected with the fixed plate 3 through bolts 10 .

A hand-operated fastener for the inner ring of the core mold of the pipe gallery anchor according to the present invention, as shown in the figure, the outer mold 14 and the core mold 15 are arranged on the left side of the anchoring groove, and the steel cable 16 passes through the middle When in use, put the fastener of the present invention into the anchoring groove, the lower end of the fixing plate 3 extends into the right side of the anchoring groove, the "U" groove 5 is stuck on the steel cable 16, and the "U" groove 5 sticks to the core Die 15, now there is a gap between the rightmost nut 9 of the adjustment screw 1 and the fixed plate 3, the connection between the bolt 10 and the right side of the force transmission plate 4 is not tightly connected, the bolt head of the bolt 10 is connected to the side of the fixed plate 3 There is also a gap between them. When in use, hold the handle 6 with the left hand and turn the nut 9 with the right hand to move the upper end of the fixed plate 3 to the middle. When moving to the right, the pressure generated will reversely push the fastener as a whole to move to the left, the left side under the dial 2 presses the mandrel 15, presses the mandrel 15 into the outer mold 14, and locks the steel cable 16. The present invention changes the previous method of man-made oblique knocking. The steel cable 16 has a good tightening effect, saves labor, has a simple and scientific structure, is convenient to use, and is safe and reliable.
