Background

Radiographic testing is a conventional non-destructive testing technique in which the test placement process is critical to radiographic testing quality control. In the past, most of detected products are small, and the detected products can be transferred to a ray machine by one person or at most two persons; at present, large-scale detection products are more and more, the maximum detection product weight reaches one ton, and it is obviously unrealistic to transfer by manpower alone, and the detection product can be transferred to the lower part of the ray machine only by depending on hoisting equipment. However, the detection arrangement process is not simple, the detection product is placed under the ray machine, the detection product has the detection requirements of transillumination position, angle and the like, and if the detection product is a small detection product, the detection requirements can be easily realized by means of manual arrangement; however, the placement and arrangement of a heavy object of one ton is very difficult by controlling the crane, and the swinging of the heavy object of one ton in the falling and moving processes is very difficult to control by two people and can injure operators carelessly, so that the detection and arrangement process of the large-scale engine needs to be very careful and slow, the technical requirements of the detection and arrangement need to be considered, the personnel are prevented from being injured, and the detection efficiency is very low.

SUMMERY OF THE UTILITY MODEL

Arrange the degree of safety in order to improve detection efficiency and operation, the utility model provides a frock is arranged in photographic detection of large-scale rocket engine has effectively solved the technological problem of this process.

The utility model provides a following technical scheme:

a photographic detection arrangement tool for a large rocket engine comprises a roller support and a plurality of film supporting frames, wherein the roller support comprises a support body, universal casters are arranged at four bottom corners of the support body, two guide rails are arranged on the support body, two cross beams are erected between the two guide rails, and two supporting rollers are symmetrically arranged on the cross beams; the film support frame comprises a base with universal casters, a hydraulic lifting mechanism is arranged on the base, a film carrying platform is arranged at the top of the hydraulic lifting mechanism, and two triangular wedge blocks are symmetrically arranged on the film carrying platform.

Furthermore, a sliding groove is formed in the guide rail, a positioning bolt is arranged on the cross beam, and the positioning bolt is connected with the sliding groove.

Further, the film carrying platform is formed by overlapping a lead plate and a steel plate.

Furthermore, the hydraulic lifting mechanism is a jack.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a one set of independent frock that increases on current instrument and equipment.

2. The utility model discloses only need hang the product to the gyro wheel support back with the help of the hoist, whole testing process just can accomplish alone, has reduced intensity of labour, has practiced thrift the human cost.

3. Because there is the utility model discloses a guarantee, not only safe and reliable has greatly improved detection efficiency moreover, by the single detection rate (20 hours/send out) in the past one day night, improves to 10 hours/send out.

4. The utility model discloses can effectively guarantee to detect the uniformity.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

x-ray photography nondestructive testing equipment is mainly a ray machine, a test product is generally placed under the ray machine, and transillumination is carried out by rotating or staggering a certain angle with the ray machine according to the test requirement. For smaller size and lighter weight inspection products (which are moved by ordinary people), the inspection arrangement can be completed only by means of the tape measure and the angle ruler, and fig. 3 is a small-sized equipment inspection arrangement. The detection of large products is completed by means of tools and tools.

Referring to fig. 1 and 2, the photo-taking detection arrangement tool for large rocket engines of the present invention comprises a roller support 1 and a plurality of film support frames 2, wherein the roller support 1 comprises a support body 11, four bottom corners of the support body 11 are provided with universal casters 12, the support body 11 is provided with two guide rails 13, two beams 14 are erected between the two guide rails 13, and the beams 14 are symmetrically provided with two support rollers 15; the film supporting frame 2 comprises a base 21 with a universal caster, a hydraulic lifting mechanism 22 is arranged on the base 21, a film carrying platform 23 is arranged at the top of the hydraulic lifting mechanism 22, and two triangular wedge blocks 24 are symmetrically arranged on the film carrying platform 23.

In this embodiment, the guide rail 13 is provided with a sliding groove 131, the cross beam 14 is provided with a positioning bolt 141, and the positioning bolt 141 is connected with the sliding groove 131. The cross beams 14 move along the sliding grooves 131 on the guide rails 13 through the positioning bolts 141, the distance between the two cross beams 14 can be adjusted according to the length of the bearing equipment, and finally the bottoms of the sliding grooves 131 are pressed and fixed through the positioning bolts 141, so that the roller bracket 1 is more stable in bearing equipment.

In this embodiment, the film stage 23 is formed by stacking a lead plate and a steel plate.

In this embodiment, the hydraulic lifting mechanism 22 is a jack. The universal caster wheels are provided with brake mechanisms.

The photo detection layout flow is specifically as follows:

the method comprises the steps of placing a detection workpiece on a roller wheel bracket (shown in figure 1) through hoisting equipment, and rotating the detection workpiece to an angle position to be detected by a rotating supporting roller;

secondly, moving the two film supports to two ends of a detection workpiece (shown in figure 1), jacking the workpiece through a hydraulic lifting mechanism, withdrawing the roller supports, placing a third film support below the workpiece (shown in figure 2), then decompressing the film supports on the two sides, uniformly distributing the weight of the detection workpiece on the three film supports, and fixing the detection workpiece by using a triangular wedge block without rolling;

in the detection process, the film can be taken out smoothly only by lifting any two film supporting frames without films, then the film supporting frames are replaced with new films, the new films are moved to the next detection position, and the operation of the step 2 is repeated;

and fourthly, after one angle of the workpiece is detected, repeating the step 1.

The utility model discloses a to large-scale solid rocket engine, powder grain and design and development, this frock is hydraulic pressure lift, rotation angle and several partial functions of shift position mainly. After improvement, due to the guarantee of the tool, the problem of errors of transillumination angles is solved (about 200 in the past), and the detection efficiency is doubled.
