FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic view of a portion of the structure of fig. 1.
The reference numerals in the drawings are as follows:
1. A fixing frame; 101. a round bar; 3. a movable frame; 41. a hoist; 42. a pulley; 51. an X-ray machine; 52. receiving an imaging backplane; 54. a probe.
Detailed Description
The utility model will now be described in detail with reference to the drawings and to specific embodiments.
Examples: as shown in fig. 1-2:
the radiographic inspection apparatus includes an X-ray machine 51, a receiving imaging floor 52.
The fixed frame 1 is formed by splicing hollow rods, wherein two hollow rods are parallel to each other and are vertically arranged to form a round rod 101; the windlass 41 is arranged at the top of the fixed frame 1;
The movable frame 3 is spliced by hollow rods to form a lower weight, the receiving imaging bottom plate 52 is arranged at the upper part of the movable frame 3, and the X-ray machine 51 and the probe 54 are arranged at the lower part of the movable frame 3; and the X-ray machine 51 and the receiving imaging floor 52 are both located below the hoist 41;
The pulleys 42 are rotatably connected to the movable frame 3, four groups of pulleys 42 are arranged on the left side and the right side of the upper part of the movable frame 3, the concave outer circumferential surface of each pulley 42 is matched with the shape of the round rod 101, and the pulleys 42 are in linear rolling fit on the round rod 101; the four sets of pulleys 42 are distributed on two opposite sides of the corresponding round rod 101 in pairs, so that the pulleys 42 are always abutted against the round rod 101, and the round rod 101 is limited through the four sets of pulleys 42 under the condition of small contact area.
The rolling fit of the pulley 42 and the round rod 101 is lower in friction force and simpler in structure, so that stability is higher, and the resistance of the sliding block slide rail is easy to be increased due to the fact that small particles enter the sliding block slide rail when the sliding block slide rail is used in an external environment. And even if the pulley 42 cannot rotate due to small particles entering, the contact area of the pulley 42 and the round bar 101 is small, so that the influence on the whole resistance is small.
The roller shaft of the winch 41 is connected with a traction rope, the other end of the traction rope is connected with the movable frame 3, and the winch 41 acts to wind or release the traction rope, so that the traction movable frame 3 can be driven to ascend in a straight line relative to the fixed frame 1 or descend by means of dead weight. In this process, the pulley 42 plays a guiding role with respect to the linear rolling on the round bar 101.
The movable frame 3 is oppositely arranged at the inner side of the fixed frame 1, so that the upper limit and the lower limit of the movable frame 3 are limited by the top wall and the lower wall of the fixed frame 1.
In the process that the radiographic inspection equipment moves relative to the power transmission line, the probe 54 is used for photographing/video recording of the power transmission line, so that appearance inspection of the inspected part of the power transmission line is realized, and accurate positioning basis is provided for horizontal movement and vertical lifting.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
