In order to achieve the above purpose, the utility model provides the following technical scheme:
the utility model provides a positioning device for a double-loop hydraulic system, which comprises a bearing plate, a locking plate and a clamping piece, wherein a steel strand sequentially passes through the bearing plate and the locking plate, the clamping piece is embedded on the locking plate and is used for clamping the steel strand, the contact surface of the bearing plate and the locking plate is of a plane structure, the clamping piece comprises a pair of half clamping pieces which are separately arranged, and the half clamping pieces surround an inverted cone-shaped positioning hole.
Furthermore, the locking plate is provided with a mounting hole for mounting the half clamping piece, and when the bearing plate is abutted against the locking plate, the half clamping piece is accommodated in the positioning hole and clamps the steel strand.
Further, an internal thread is arranged in each half clamping piece.
The technical scheme of the utility model has the following beneficial effects:
according to the positioning device for the double-loop hydraulic system, the contact surface of the bearing plate and the locking plate is arranged to be of a plane structure, the half clamping pieces surround the inverted-cone-shaped positioning hole, when the anchorage force is designed in a stretching mode, the hydraulic inner oil cylinder pushes the bearing plate inwards to firmly lock the clamping pieces and the steel strands on the locking plate, so that the anchorage locking is completed, the stability of the anchored force after locking is high, and the pulling force is not easy to lose.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
In the present invention, unless expressly stated or limited otherwise, the terms "connected," "secured," and the like are to be construed broadly, and for example, "connected" may be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In addition, the descriptions related to "first", "second", etc. in the present invention are only for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
Referring to fig. 1 to 6, the present invention provides a positioning device 100 for a dual-circuit hydraulic system, including a bearing plate 10, a locking plate 20, and a clamping piece 30, wherein a steel strand 40 sequentially passes through the bearing plate 10 and the locking plate 20, the clamping piece 30 is embedded on the locking plate 20 for clamping the steel strand 40, a contact surface between the bearing plate 10 and the locking plate 20 is a planar structure, the clamping piece 30 includes a pair of half clamping pieces 31 separately disposed, and the half clamping pieces 31 enclose an inverted cone-shaped positioning hole 32.
