Problems solved by technology

[0002] At present, in the artificial drilling construction of our spiral anchor foundation, various temporary clamps are usually installed on the spiral anchor bolt. Since the clamps are temporary and have different specifications, it is inconvenient to transport and carry, and reduces the construction drilling. Accuracy seriously affects the life of the screw anchor bolt and brings huge troubles to the engineering construction

Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific embodiments.

[0011] refer to figure 1 , figure 2 , image 3 , the artificial drilling jig is composed of two semicircular clamp rings 2 and a rotating arm rod 1 set up opposite to the anchor rod. The rotating arm rod 1 is welded on the outer circle of the semicircular clamp ring 2, and the rotating arm rod 1 is It is covered with reinforced steel pipes, and there are positioning connecting pieces 3 at both ends of the semicircular clamping ring 2. Corresponding screw holes 4 are arranged on the positioning connecting piece 3, and the two semicircular clamping rings 2 are connected by bolts.

[0012] When in use, place the screw anchor bolts in two semicircular clamp rings 2 so that the corresponding screw holes 4 on the positioning connecting pieces 3 at both ends of the semicircular clamp rings 2 coincide, and then use bolts to pass through the screw holes 4. Hole 4, tighten the tw...

Abstract

The invention relates to an artificial drilling clamp, and belongs to the technical field of mechanical clamps. The artificial drilling clamp consists of two semicircular clamping rings arranged relative to an anchor rod and rotary arm rods, wherein the rotary arm rods are welded on the clamping rings; and the clamping rings are connected through bolts. The artificial drilling clamp has the advantages of flexible use, simple installation, convenience for transportation and carrying and improvement on construction and drilling precision.

Description

technical field [0001] The invention belongs to the technical field of mechanical clamps, in particular to a manual drilling clamp. Background technique [0002] At present, in the manual drilling construction of our spiral anchor foundation, various temporary clamps are usually installed on the spiral anchor bolt. Since the clamps are temporary and have different specifications, it is inconvenient to transport and carry, and reduces the construction drilling. Accuracy seriously affects the life of the screw anchor bolt and brings huge troubles to the engineering construction. Contents of the invention [0003] The purpose of the present invention is to provide an artificial drilling jig that is flexible in use, easy to carry, improves the drilling precision of construction, and prolongs the service life of the anti-corrosion layer on the surface of the spiral anchor. [0004] The artificial drilling jig of the present invention is composed of two semicircular clamp rings...
