Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model, the technical scheme in this utility model is clearly and completely described.
Refer to Fig. 1 and Fig. 2, this utility model provides a kind of prestressed pore passage device for fast detecting, including hollow circular cylinder 1 and the hollow cone 2 that is connected with hollow circular cylinder 1 two ends, hollow circular cylinder 1 and hollow cone 2 are made by iron sheet, and a steel bundle insertion hole 3 inserted for steel strand wires is offered at the tip of hollow cone 2.
At the two ends of hollow circular cylinder 1, hollow cone 2 is set, the design of cone can reduce resistance, increase the device property passed through in duct, two ends all arrange hollow cone 2 can realize two-way drawing, can reversely extract out when forward enters and is obstructed, and by dilatory back and forth can the not high sprue of crushing strength.
The total length of hollow circular cylinder 1 and two hollow cone 2 is 10-15cm, with control its can simulate whole hole steel bundle bending duct in pass through. The thickness of hollow circular cylinder 1 and hollow cone 2 is generally 3-5mm, slightly thicker than managing used by duct. The diameter of hollow circular cylinder 1 5-10mm less of prestressed pore passage internal diameter. The diameter that steel bundle inserts hole 3 is consistent with single steel strand diameter, it is possible to inserted by steel strand wires.
Using method of the present utility model is described below:
Before using, first by the dragline steel strand wires 5 greatest length according to a collection of duct and consider that surplus carries out blanking, first by the Dan Shu of dragline steel strand wires through duct, the steel bundle that then its one end is inserted in one of hollow cone 2 inserts hole 3 (about 50mm), steel bundle and steel bundle are inserted hole 3 periphery and carries out tunneling boring welding, form solder joint 4 (as shown in Figure 3).
Reserve after hauling rope steel strand wires until lashing, the steel bundle of the hauling rope steel strand wires 6 and another one hollow cone 2 for the treatment of lashing is inserted hole 3 periphery and carries out tunneling boring welding, form another one solder joint 4.
Use the other end of chain block rear haulage equipment traction dragline steel strand wires 5, once meet with obstruction in distraction procedure, obstacle location can be positioned according to the scale 8 being located on dragline steel strand wires 5, according to graduation position, such as show and pulled out 40m, so obstacle should near 40m, and according to different radians, suitably some changes. Scale generally can be arranged according to 1m. When this device is drawn through the other end from one section of duct, treat lashing also therewith lashing complete.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any belong to those skilled in the art in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
