Abstract
Disclosed in the utility model, a kind of simple and easy tunnel point setter, comprises at least two poles, and be threaded connection between adjacent two poles, the one end being positioned at the pole of end is provided with groove.The simple and easy tunnel point setter that the utility model provides, the main detachable two or more pole compositions installed, structure is simple, easy to carry, pole can select waste and old anchor pole or iron and steel to make, cost is lower, and especially a people can complete the work of back fixed point easily, saves manpower and time.
Description
Technical field
The utility model relates to fixed-point apparatus, is specifically related to a kind of simple and easy tunnel point setter.
Background technology
In mine routine work, Di Ce department needs to carry out through at underworkings, the measurements such as wire, underground survey is because pucking distortion is fast, top board is relatively stable, so all take a little upper Alignment measuring i.e. location survey point on back, but the progress along with science and technology and the requirement to safety, present underworkings mostly is large section roadway, wide 4.6 meters, high 3.6 meters, when carrying out measurement operation, often because tunnel is high, not easily to fix a point bracing wire and wasting time, a fixed point needs three people to coordinate, also with tank car or draw ladder just can fulfil assignment, very hard and dangerous.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple and easy tunnel point setter, and a people just can complete easily in the work of back fixed point.
The purpose of this utility model realizes with following technical proposals:
A kind of simple and easy tunnel point setter, comprise at least two poles, be threaded connection between adjacent two poles, the one end being positioned at the pole of end is provided with groove.
When described pole pole is two, there are external thread or internal thread in pole I one end, and pole II establishes one end internal thread corresponding to pole I or external thread, and the pole II other end is provided with groove;
Described pole is steel or ironwork.
The simple and easy tunnel point setter that the utility model provides, the main detachable two or more pole compositions installed, structure is simple, easy to carry, pole can select waste and old anchor pole or iron and steel to make, cost is lower, and especially a people can complete the work of back fixed point easily, saves manpower and time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cut-open view of the present utility model.
Embodiment
The simple and easy tunnel point setter that the utility model provides, as shown in Figures 1 and 2, comprise two poles, there is external thread 3 pole I1 one end, pole II2 establishes one end corresponding internal thread 4, and it is a long fulcrum bar that pole I1 can be connected through screw thread with pole II2, and two poles length of adding up adds that the height of people is wanted to reach head-room, internal thread 4 also can be established in certain pole I1 one end, and pole II2 establishes one end corresponding external thread 3; The pole II2 other end is provided with groove 5; Groove 5 be used for place fixed point cement nail or other object.
When the utility model does not use, two poles can separately be deposited, when needs carry out measurement operation, when needing fixed point bracing wire, two poles are threaded, groove 5 places cement nail, a people lifts pole, exerts oneself to back, cement nail directly can be followed closely on top board, because back has certain hardness, therefore texture material is preferably steel or iron.
It is pointed out that pole also can be and be greater than two, be threaded connection between adjacent two poles, the one end being positioned at the pole of end is provided with groove.Pole is connected successively during use.Pole is more, Vietnamese side's Portable belt, but there is the time taking problem of connection simultaneously, can selectivity use according to demand.
Claims (3)
