Abstract
The utility model discloses expansion links used in a flaw detection crane. The expansion links used in the flaw detection crane comprises at least two expansion links (1), wherein a shaft sleeve (2) connected with one expansion link (1) is arranged on an inner wall of one end of the expansion link (1), one end of the other expansion link (1) is inserted into the shaft sleeve (2), and a baffle (3) is arranged on the end face of the end. A cross section of the expansion link (1) is round. The expansion links used in the flaw detection crane has the advantages of being simple in structure and convenient to manufacture. The expansion links are enabled to be closely matched, accurate guiding is achieved, and anti-deflection performance is good.
Description
Technical field
The utility model relates to a kind of flaw detection and hangs, particularly a kind of flexible rod that hangs for flaw detection.
Background technique
The existing flexible rod that hangs for flaw detection is comprised of several square tubes or welding box-shaped beam, the square tube that boundary dimension is little is assemblied in the large square tube of boundary dimension, moving linearly between square tube and the square tube, thereby reach the purpose of flexible guiding, although this connection can be played flexible purpose, but, the Telescopic rod structure that this square tube or welding box-shaped beam form, processing is very inconvenient, and when welding, the deviation between square tube and square tube is not easy control, so, so that the steering capability of flexible rod is relatively poor.
The model utility content
The purpose of this utility model just provides the flexible rod that flaw detection is hung that is used for that a kind of convenience is processed, steering capability is good.
The purpose of this utility model is to realize by such technological scheme, a kind of flexible rod that hangs for flaw detection, comprise at least two flexible rods, be provided with the axle sleeve that is connected with this flexible rod on the inwall of one end of a described wherein flexible rod, one end of described another root flexible rod penetrates in the axle sleeve, and the end face at this end is provided with baffle plate, and the cross section of described flexible rod is circular.
In order to prevent that flexible rod from rotating, described to be provided with the guiding of stretching out axle sleeve at axle sleeve strong, is provided with groove at the outer wall of flexible rod, and the strong external part of described guiding is positioned at groove.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to process, adopt it so that cooperate tightly between the flexible rod, can play accurate guiding, anti-bias pendulosity is good.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the zoomed-in view of B section among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, 3, a kind of flexible rod that hangs for flaw detection, comprise at least two flexible rods 1, be provided with the axle sleeve 2 that is connected with this flexible rod 1 on the inwall of one end of a described wherein flexible rod 1, one end of described another root flexible rod 1 penetrates in the axle sleeve 2, and the end face at this end is provided with baffle plate 3, and the cross section of described flexible rod 1 is circular.
In the utility model, the radical of flexible rod is 4, certainly, during use, can increase or reduce according to actual conditions the radical of flexible rod.
In the utility model, flexible rod 1 a large end is connected with trolley frame 6 bottoms, and a little end is connected with suspender or anchor clamps 7, gets final product.Wherein, make free straight line motion by Spielpassung between the flexible rod 1.Because flexible rod 1 is that circular steel pipe forms by cross section, the proportional increase of the diameter of steel pipe, the steel pipe that diameter is little is assemblied in the large steel pipe of diameter, moving linearly between steel pipe and steel pipe, thus reach the flexible purpose that leads, and, the processing of circular steel pipe is comparatively convenient, and guidance quality is good.
Further, described to be provided with the guiding of stretching out axle sleeve 2 at axle sleeve 2 strong 4, is provided with groove 5 at the outer wall of flexible rod 1, and the external part of described guiding strong 4 is positioned at groove 5, do like this, and be in order to prevent that in telescopic process flexible rod 1 rotates.
Claims (2)
1. one kind is used for the flexible rod that flaw detection is hung, comprise at least two flexible rods (1), be provided with the axle sleeve (2) that is connected with this flexible rod (1) on the inwall of a described wherein end of a flexible rod (1), one end of described another root flexible rod (1) penetrates in the axle sleeve (2), and the end face at this end is provided with baffle plate (3), it is characterized in that: the cross section of described flexible rod (1) is for circular.
2. the flexible rod that hangs for flaw detection as claimed in claim 1, it is characterized in that: the described guiding strong (4) of stretching out axle sleeve (2) that is provided with at axle sleeve (2), outer wall at flexible rod (1) is provided with groove (5), and the external part of described guiding strong (4) is positioned at groove (5).
