Abstract
The utility model discloses a link device can be dismantled to rotation type for tunnel convergence detects, tie and the inflation screw including link, rectangle steel sheet, steel, the lower surface of rectangle steel sheet middle part is equipped with and expands screw assorted screw hole, and the upper surface bilateral symmetry of rectangle steel sheet is equipped with two horizontal steel pipes, and the top of rectangle steel sheet is equipped with the link, and the link lower extreme is equipped with the connecting rod, and the connecting rod lower extreme is equipped with the steel pipe, the steel pipe is located between two horizontal steel pipes, the steel is tied the middle part and is passed steel pipe and two horizontal steel pipes, and the both ends that the steel was tied are equipped with the end. The utility model discloses a link movable mounting laminates the link energy of rotation during use on the rectangle steel sheet better with the tunnel inner wall, effectively keep measuring accuracy nature, and in tunnel construction process, link and reflection of light piece can effectively be avoided dropping because of the produced deformation of the collision of platform truck, forklift, enrockment damages even, and what assurance detection achievement and tunnel construction worked goes on smoothly.
Description
Technical field
The utility model relates to a kind of tunnel convergence checkout gear, particularly a kind of rotary detachable link device detected for tunnel convergence.
Background technology
In the tunnel convergence testing process of advance geologic prediction, hook need be arranged in same section both sides and top, hole in tunnel, if reflecting piece need be pasted on hook when using total station survey, because tunnel all must carry out convergence measurement every day, and constructing tunnel carries out simultaneously, chassis is had in tunnel, forklift, excavators etc. are operation in hole, ground slag is deposited in again both sides and can not clears up rapidly, cause hooking device and reflecting piece often to be damaged even to drop, and detection person must coordinate chassis to rearrange hooking device when not constructing, make surveying work amount increase and affect unit in charge of construction and complete construction speed on time.In addition, when two lining constructions are carried out, need to arrange water blocking tape water-proof strip, therefore must clear up these outstanding sharp things and prevent from making it damaged, and common one hooking device is difficult to process, even can damage initial support during process.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides that a kind of structure is simple, easy accessibility and the rotary detachable link device detected for tunnel convergence that can reuse.
The technical scheme that the utility model solves the problem is: a kind of rotary detachable link device detected for tunnel convergence, comprise link, rectangle steel disc, steel bolt and setscrew, the screwed hole matched with setscrew is provided with in the middle part of the soffit of described rectangle steel disc, the upper surface bilateral symmetry of rectangle steel disc is provided with two horizontal steel pipes, the top of rectangle steel disc is provided with link, link lower end is provided with connecting rod, connecting rod lower end is provided with steel pipe, described steel pipe is between two horizontal steel pipes, through steel pipe and two horizontal steel pipes in the middle part of described steel bolt, the two ends of steel bolt are provided with termination.
In the above-mentioned rotary detachable link device for tunnel convergence detection, the outer wall of described steel pipe is provided with rectangle bloom, linear vertical rectangle bloom place, connecting rod place horizontal plane.
In the above-mentioned rotary detachable link device for tunnel convergence detection, described link is provided with reflecting piece.
The beneficial effects of the utility model are:
1, link of the present utility model is movably arranged on rectangle steel disc, during use, link is rotated and can fit with tunnel inner wall better, effective accuracy keeping measuring, in constructing tunnel process, link and reflecting piece can effectively be avoided the distortion that collision produces because of chassis, forklift, enrockment even to damage dropping, and ensure carrying out smoothly of testing and constructing tunnel work;
2, detachability of the present utility model protects that to have stopped waterproof tape damaged effectively, and recyclable recycling, has saved cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises link 1, steel pipe 2, rectangle bloom 3, horizontal steel pipe 4, steel bolt 6, rectangle steel disc 7 and setscrew 9, the screwed hole 8 matched with setscrew 9 is provided with in the middle part of the soffit of described rectangle steel disc 7, the upper surface both sides that two horizontal steel pipes 4 are symmetrically welded at rectangle steel disc 7 form an entirety, the top of rectangle steel disc 7 is provided with link 1, link 1 lower end is welded with connecting rod 5, connecting rod 5 lower end is welded with steel pipe 2, link 1, connecting rod 5, steel pipe 2 forms link entirety, the outer wall of steel pipe 2 is provided with rectangle bloom 3, linear vertical rectangle bloom 3 place, connecting rod 5 place horizontal plane, described steel pipe 2 is between two horizontal steel pipes 4, through steel pipe 2 and two horizontal steel pipes 4 in the middle part of described steel bolt 6, the two ends of steel bolt 6 are provided with termination.Described link 1 is provided with reflecting piece.
Specific implementation process of the present utility model is: punch at Tunnel wall with Churn drill, again setscrew 9 is anchored among the wall of hole, again link device is fully connected with setscrew 9 by screwed hole 8, then convergence measurement is carried out with convergence gauge, if use total station survey, then need paste reflecting piece on link 1; During measurement, link integral-rotation link 1, connecting rod 5, steel pipe 2 formed is to vertical with rectangle steel disc 7, now fit in rectangle steel billet 3 lower surface and rectangle steel disc 7 surface, thus play the effect that restriction link 1 continues rotation, make this link entirety keep plumbness in measuring process, after secondary measurement completes, link 1 is broken and fit to rectangle steel disc 7, after detection engineering completes, taken off by link device to carry out two lining constructions, the link device taken off remains to and re-uses next time.
