Abstract
The invention discloses an anchor bolt drawing instrument connector, wherein the anchor bolt drawing instrument connector comprises an anchor bolt reserved in a rock face, a drawing rod, a supporting base, a hydraulic oil cylinder and a pressure sensor, wherein an anchorage device is arranged at the end part of the anchor bolt outside the rock face, the anchor bolt is in threaded connection with the drawing rod by virtue of the anchorage device, and the supporting base, the hydraulic oil cylinder and the pressure sensor sequentially pass through the drawing rod and are locked on the drawing rod by virtue of fastening nuts. By using the anchor bolt drawing instrument connector, the reserved length of an exposed anchor head of the detected anchor bolt is shortened, the influence of the exposed anchor head to subsequent construction is reduced, and the loss of the material is reduced, so that good popularization value is achieved.
Description
Technical field
The present invention relates to the device of auxiliary anchor pole pull-out test in Geotechnical Engineering, more particularly, relate to a kind of anchor rod drawing instrument connector.
Background technology
Detect the anchor force of anchor pole at present and substantially rely on anchor rod drawing test, anchor rod drawing test needs detected anchor pole anchor head protruded length to reserve 35cm to 40cm usually.Detected anchor pole anchor head protruded length is long just can affect postorder construction, especially in Tunnel Engineering, working space is narrow, anchor head protruded length is long will affect postorder excavation construction, and long anchor head is often hit curved by excavation mechinery equipment or fractures, causing anchor rod drawing to be tested cannot normally carry out.Therefore, how solving the above problems, is problem demanding prompt solution.
Summary of the invention
The object of the present invention is to provide a kind of a kind of anchor rod drawing instrument connector that can shorten anchor pole protruded length.
For realizing above-mentioned object, technical scheme of the present invention is: a kind of anchor rod drawing instrument connector, comprising the anchor pole be reserved in crag, pull bar, supporting seat, hydraulic jack, pressure inductor, anchor pole end outside crag is provided with ground tackle, anchor pole is connected with pull rod screw by ground tackle, and described supporting seat, hydraulic jack and pressure inductor are passed pull bar successively and be locked on pull bar by clamp nut.
Above-mentioned anchor rod drawing instrument connector, is provided with threaded hole in described pull bar, and ground tackle is arranged in threaded hole, its surperficial external thread that is provided with coordinates with threaded hole.
Above-mentioned anchor rod drawing instrument connector, is provided with packing ring between described clamp nut and pressure inductor; Reduce the gap between nut and pressure inductor, make the structure after locking more firm.
Above-mentioned anchor rod drawing instrument connector, is provided with backing plate between described supporting seat and crag; Prevent in the unbalanced situation of crag, supporting seat overstress and insert crag, affect anchor rod drawing test.
Above-mentioned anchor rod drawing instrument connector, is provided with backing plate between described supporting seat and crag, prevents in the unbalanced situation of crag, supporting seat overstress and insert crag, affects anchor rod drawing test.
The present invention adopts above-mentioned structure, anchor pole anchor head to be inserted in threaded hole and the ground tackle be fixed on anchor pole anchor head is threaded with the threaded hole in pull bar, pass through rotating rod, make the relative pull bar of anchor pole anchor head movable in threaded hole, realize the technical purpose shortening anchor pole anchor head protruded length, the present invention is through hole due to the threaded hole in pull bar, can, for the anchor pole anchor head of any length, make the protruded length of detected anchor pole anchor head shorten the requirement tested to meet anchor rod drawing; The present invention not only reduces the impact exposing anchor head and construct on postorder; And decrease the loss of material, there is good promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial enlargement structural representation of Fig. 1.
In figure: 1 is anchor pole anchor head, 2 is pull bar, and 21 is threaded hole, and 3 is supporting seat, and 4 is hydraulic jack, and 5 is pressure inductor, and 6 is clamp nut, and 7 is ground tackle, and 8 is packing ring, and 9 is backing plate, and A is crag.
Embodiment
As depicted in figs. 1 and 2, a kind of anchor rod drawing instrument connector, comprise the anchor pole 1 be reserved in crag A, pull bar 2, supporting seat 3, hydraulic jack 4, pressure inductor 5, anchor pole 1 end outside crag A is provided with ground tackle 7, anchor pole 1 is threaded with pull bar 2 by ground tackle 7, and described supporting seat 3, hydraulic jack 4 and pressure inductor 5 pass pull bar 2 successively and be locked on pull bar 2 by clamp nut 6; Crag A is sprayed concrete face.
Be provided with threaded hole 21 in pull bar 2, ground tackle 7 is arranged in threaded hole 21, its surperficial external thread that is provided with coordinates with threaded hole 21; Certainly, also can be provided with through hole in pull bar 2, the end of through hole is provided with internal thread and coordinates with the external thread of ground tackle 7; At this moment, for preventing ground tackle 7 from rotating excessively, depart from the scope that is threaded of pull bar 2, the endoporus of pull bar 2 is provided with position limiting structure to stop ground tackle 7, position limiting structure be pull bar 2 in reduced bore, spacing place, aperture is less than the width of ground tackle.
Packing ring 8 is provided with between clamp nut 6 and pressure inductor 5; Backing plate 9 is provided with between supporting seat 3 and crag A.
The present invention in the specific implementation, installs ground tackle 7 in detected anchor pole end, after guaranteeing that ground tackle 7 has been fixed on anchor pole 1, and pull bar 2 of screwing on, the length that adjustment anchor pole 1 exposes; Then backing plate 9 contacts with sprayed concrete face A through pull bar 2, after guaranteeing that backing plate 9 is vertical with pull bar 2, pull bar 2 overlaps upper support seat 3, hydraulic jack 4, pressure transducer 5 and packing ring 8 successively, then securing member 6 is screwed on supporting seat 3, hydraulic jack 4, pressure transducer 5 to be locked at the use spanner of pull bar 2, finally connected by pull bar 2 and loading and pressure measuring system, implement to load to anchor pole by compression system, carry out anchor rod drawing test.
In sum, the present invention, as instructions and diagramatic content, makes actual sample and through repeatedly using test, and from the effect using test, provable the present invention can reach its desired object, and practical value is unquestionable.Above illustrated embodiment is only used for conveniently illustrating the present invention, not any pro forma restriction is done to the present invention, have in any art and usually know the knowledgeable, if do not depart from the present invention carry in the scope of technical characteristic, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and do not depart from technical characteristic content of the present invention, all still belong in the scope of the technology of the present invention feature.
