[0038] Example 1

[0039] The specific embodiment of the utility model as Figures 1-9 Indicated, a kind of applicable to multi-specification pipe receiving and sending ball car, including horizontally arranged rectangular chassis 1, rectangular chassis 1 top is horizontally equipped with the receiving and sending ball support 3 of the half barrel structure of slightly smaller diameter than pipe diameter. The receiving and sending ball support 3 is mainly used to place detector 8. At the same time, in order to send detection equipment when detector 8 and receiving and sending ball support 3 are sent into to send ball barrel, and when recycling detection equipment, detector 8 is dragged back to receiving and sending ball support 3 from receiving ball barrel, rectangular chassis 1 is also equipped with push-pull assembly that can push and pull receiving and sending ball support 3, detector 8 along the axial direction of receiving and sending ball support 3.

[0040] In the receiving and sending ball car, in order to slide type installation receiving and sending ball support 3 on rectangular chassis 1, two slide rails 2 extending in the same direction with receiving and sending ball support 3 are horizontally arranged on the lower side of rectangular chassis 1, and the slide rail 2 and the outer wall of receiving and sending ball support 3 are in sliding contact. In order to make receiving and sending ball support 3 stable on two slide rails 3, the outer wall of receiving and sending ball support 3 is arranged in contact with the upper inclined surface of the opposite side of two slide rails 2. At the same time, in order to make the receiving and sending ball car can be used with a variety of diameter specifications of receiving and sending ball support 3, two slide rails 3 are installed on rectangular chassis 1 with adjustable track gauge. And, the edge of the opposite side of two slide rails 2 on rectangular chassis 1 is equipped with side stop frame 13, and at least two lifting supports 7 are arranged on each side stop frame 13 in sequence along the extension direction of receiving and sending ball support 3. By the lifting adjustment of lifting support 7, the horizontal height of receiving and sending ball support 3 can be adjusted, so as to facilitate the receiving and sending ball work of ball barrel. In the embodiment, the lifting support 7 adopts hand-operated lifting support, which belongs to prior art, specifically, the lifting support 7 adopts the FW2819ED0 supporting leg produced by Guangdong Fuhua Machinery Group Co., Ltd., so the structure thereof will not be described in detail. In addition, in order to facilitate the movement of the receiving and sending ball car, the lower end of the lifting support 7 is connected with universal wheel 71 with brake.

[0041] When the detector 8 is sent into the launching cylinder by the launching-receiving vehicle, first, the launching-receiving vehicle is moved to the launching cylinder, the quick-opening blind plate of the launching cylinder is opened, the height of the lifting support 7 is adjusted, the front end of the launching-receiving vehicle is abutted against the edge of the launching cylinder, the height of the launching-receiving vehicle support 3 is made consistent with the inner wall of the launching cylinder, the launching-receiving vehicle and the launching cylinder are connected by the tension belt, then the detector 8 is placed on the launching-receiving vehicle support 3, the front end of the detector 8 is close to the edge of the launching-receiving vehicle support 3, finally, the detector 8 and the launching-receiving vehicle support 3 are sent into the launching cylinder by the push-pull assembly, and then the launching-receiving vehicle support 3 is pulled out from the launching cylinder, thereby completing the work of sending the detector 8 into the launching cylinder.

[0042] When the detector 8 is recovered from the receiving cylinder by the launching-receiving vehicle, first, it is confirmed that the detector 8 enters the receiving cylinder, then the launching-receiving vehicle is moved to the receiving cylinder, the quick-opening blind plate of the receiving cylinder is opened, the height of the lifting support 7 is adjusted, the front end of the launching-receiving vehicle is abutted against the edge of the receiving cylinder, the height of the launching-receiving vehicle support 3 is made consistent with the inner wall of the receiving cylinder, and the launching-receiving vehicle and the receiving cylinder are connected by the tension belt, finally, the detector 8 is pulled out from the receiving cylinder to the launching-receiving vehicle support 3 by the push-pull assembly, thereby completing the work of taking out the detector 8 from the receiving cylinder.

[0043] The launching-receiving vehicle can stably slide the launching-receiving vehicle support 3 of various radial sizes on the two slide rails 2 by adjusting the track gauge of the two slide rails 2, thereby completing the launching-receiving work of the cylinder of various specifications and sizes, and further cooperating with the pipeline of various specifications and sizes to complete the detection work in the pipeline. Therefore, the launching-receiving vehicle has a large application range, so that the launching-receiving vehicle does not need to be frequently replaced when the detection work in the pipeline of multiple specifications is performed, thereby facilitating the detection work in the pipeline. Meanwhile, the launching-receiving vehicle with a large application range also reduces the purchase demand of the launching-receiving vehicle, thereby also reducing the use cost.

[0044] In the launching-receiving vehicle, in order to adjust the track gauge between the two slide rails 2, as shown in Figure 7 The rectangular chassis 1 below the slide rail 2 is horizontally provided with at least two cross beams 11 for mounting the slide rail 2. The two cross beams 11 are arranged in sequence along the extension direction of the launching-receiving vehicle support 3, and the extension direction of the cross beam 11 is perpendicular to the extension direction of the launching-receiving vehicle support 3. Specifically, in order to mount the slide rail 2 on the cross beam 11, the cross beam 11 below the slide rail 2 is provided with a plurality of groups of fixed screw holes 21 arranged in sequence along the extension direction of the cross beam 11. The slide rail 2 is detachably connected with one of the groups of fixed screw holes 21 by a fixed screw.

When the lower hydraulic cylinder 5 reaches the maximum stroke, the connection between the lower hydraulic cylinder 5 and the ball receiving holder 3 is disconnected, and the lower hydraulic cylinder 5 is retracted. Then, a new push-pull pipe 6 is connected to the lower hydraulic cylinder 5 and the push-pull pipe 6 at both ends, and the process is repeated until the ball receiving holder 3 and the detector 8 are pushed into the pipe connection between the large head and the small head of the ball sending cylinder. Then, a plurality of push-pull pipes 6 are sequentially connected, and the upper hydraulic cylinder 4 is started. At the same time, the two ends of the push-pull pipe group are connected to the upper hydraulic cylinder 4 and the detector 8, respectively, to push the detector 8 and prevent it from retreating.

The lower hydraulic cylinder 5 is extended again to connect to the remaining push-pull pipe 6 closest to the lower hydraulic cylinder 5. The process is repeated to achieve the purpose of withdrawing the ball receiving holder 3 from the ball sending cylinder. Finally, the connection between the upper hydraulic cylinder 4 and the push-pull pipe 6 is disconnected, the upper hydraulic cylinder 4 is retracted to the initial position, and the push-pull pipe group and the detector 8 are disconnected, thereby realizing the work flow of sending the detector 8 into the ball sending cylinder by the push-pull assembly.

[0047] When the detector 8 is recovered from the ball receiving cylinder by the ball sending and receiving vehicle, a plurality of push-pull pipes 6 are sequentially connected, and the upper hydraulic cylinder 4 is started. At the same time, the two ends of the push-pull pipe group are connected to the upper hydraulic cylinder 4 and the detector 8, respectively. At the same time, the lower hydraulic cylinder 5 is started and connected to the end face of the ball receiving holder 3 directly or through the push-pull pipe 6, thereby pushing the ball receiving holder 3 and preventing it from retreating. Then, the upper hydraulic cylinder 4 is retracted to the initial position, and a push-pull pipe 6 connected to the upper hydraulic cylinder 4 is removed. The upper hydraulic cylinder 4 is extended again to connect to the remaining push-pull pipe 6 closest to the upper hydraulic cylinder 4. The process is repeated to achieve the purpose of removing the detector 8 from the ball receiving cylinder.

[0048] In this embodiment, in order to realize the quick release connection between the above-mentioned components, as shown in the figure, the upper hydraulic cylinder 4 and the push-pull pipe 6, and the lower hydraulic cylinder 5 and the push-pull pipe 6 are all connected in a sleeve fitting manner, and are connected in a quick release manner through a connecting bolt 62 vertically penetrating the entire sleeve fitting part.

[0050] A detector connecting tube 65 is provided between the push-pull tube 6 and the detector 8. One end of the detector connecting tube 65 is sleeved onto the push-pull tube 6, and both are quickly connected via a connecting bolt 62 that runs vertically through the entire sleeve. The other end of the detector connecting tube 65 is threadedly connected to a raised portion on the end face of the detector 8 via a tightening sleeve 651.

[0051] A ball-holder connecting tube 64 is installed between the push-pull tube 6 and the ball-holder 3.
