But set up in the hemisphere installation cavity through with sliding seat and hemisphere installation cavity looks adaptation and universal rotation, utilize the relative rotation between sliding seat and the fixing base to adjust the axis direction of top piercing jack, make axis direction and stock axis coincidence, can effectively avoid the stock to buckle, can accurately reflect the anti-drawing force of stock, guarantee the authenticity of testing result.
Description
Technical Field
The utility model belongs to the technical field of the detection device technique and specifically relates to indicate an angularly adjustable stock is drawn and is detected counterforce device.
Background
At present, the anchor rod has wide application in slope engineering, foundation pit engineering and tunnel engineering as a main reinforcing mode, the anchor rod drawing detection is a reliable mode for detecting the reinforcing effect, and a penetrating jack and a loading counterforce device are combined to be used as an anchor rod drawing detection device to draw the anchor rod. In the actual detection process, especially in the slope anchor rod detection, the anchor rod and the slope are not perpendicular, but have an included angle, which is generally 60-80 degrees. In the existing anchor rod detection and monitoring technical regulation (JGJ/T401 and 2017), due to the existence of the included angle, the jacking direction of the feed-through jack is not coincident with the axis direction of the anchor rod in the detection process, so that the anchor rod at the exposed section is bent, the anti-drawing force of the anchor rod cannot be accurately reflected, and the detection result is distorted.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model discloses to the disappearance that prior art exists, its main objective provides an angularly adjustable stock draws and detects counterforce device, and it can effectively solve current stock and draw detection device and can make the problem that exposes section stock and buckle in the testing process.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an angle-adjustable anchor rod drawing detection counterforce device comprises a fixed seat and a movable seat; the top of the fixed seat is provided with a hemispherical installation cavity, and the bottom of the fixed seat is provided with a horn-shaped opening communicated with the hemispherical installation cavity; this movable seat is the hemisphere, and the movable seat sets up in the hemisphere installation cavity with hemisphere installation cavity looks adaptation and universal rotation, and the through-hole that supplies the stock to pass is seted up at the center of movable seat.
Preferably, the fixing seat is a steel component.
Preferably, the movable seat is a steel member.
Preferably, the fixing seat is cylindrical.
Preferably, the top surface of the movable seat is a horizontal surface.
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:
but set up in the hemisphere installation cavity through with sliding seat and hemisphere installation cavity looks adaptation and universal rotation, utilize the relative rotation between sliding seat and the fixing base to adjust the axis direction of top piercing jack, make axis direction and stock axis coincidence, can effectively avoid the stock to buckle, can accurately reflect the anti-drawing force of stock, guarantee the authenticity of testing result.
To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Detailed Description
Referring to fig. 1 to 4, a specific structure of a preferred embodiment of the present invention is shown, which includes a fixed seat 10 and a movable seat 20.
The top of the fixed seat 10 is provided with a hemispherical installation cavity 11, and the bottom of the fixed seat 10 is provided with a horn-shaped opening 12 communicated with the hemispherical installation cavity 11; in this embodiment, the fixing seat 10 is a steel member, and the fixing seat 10 has a cylindrical shape.
This sliding seat 20 is the hemisphere, and sliding seat 20 sets up in hemisphere installation cavity 11 with hemisphere installation cavity 11 looks adaptation and universal rotation, and the through-hole 21 that supplies stock 30 to pass is seted up at the center of sliding seat 20. In this embodiment, the movable seat 20 is a steel member, and the top surface of the movable seat 20 is a horizontal surface.
Detailed description the working principle of the present embodiment is as follows:
when the device is used, the fixed seat 10 is fixed on a supporting structure 41, a jack 42 is fixed at the top of the movable seat 20, a steel backing plate 43 is fixed on the jack 42, an anchor 44 is fixed on the steel backing plate 43, a clamping piece 45 is fixed on the anchor 44, the anchor rod 30 sequentially penetrates through the supporting structure 41, the horn-shaped opening 12 of the fixed seat 10, the hemispherical installation cavity 11, the through hole 21 of the movable seat 20, the jack 42, the steel backing plate 43, the anchor 44 and the clamping piece 45, the clamping piece 45 tightly clamps the anchor rod 30, the fixed seat 10 takes the supporting structure 41 as an action surface during detection, the supporting structure 41 can be a side slope lattice beam or a foundation pit side wall concrete surface, and the axial direction of the top center-penetrating jack 42 is adjusted by utilizing the relative rotation between the movable seat 20 and the fixed seat 10, so that the axial direction coincides with the axial line of the anchor rod 30, and the bending of the.
The utility model discloses a design key is: but set up in the hemisphere installation cavity through with sliding seat and hemisphere installation cavity looks adaptation and universal rotation, utilize the relative rotation between sliding seat and the fixing base to adjust the axis direction of top piercing jack, make axis direction and stock axis coincidence, can effectively avoid the stock to buckle, can accurately reflect the anti-drawing force of stock, guarantee the authenticity of testing result.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
