[0014] Figure 1 It is an overall structural diagram of the utility model pipe explosion test protection device. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, a pipe explosion test protection device of the utility model comprises a base plate 1, a guide rod 3, a protective cover 5, a side limit plate 2, and a slider 4. The two sides of the base plate 1 are fixedly connected with a side limit plate 2, the two ends of the guide rod 3 are respectively connected to the side limit plates 2, the slider 4 is slidably connected to the guide rod 3, one end of the test piece 6 is connected to the side limit plate 2, and the other end is connected to the slider 4, one end of the test piece 6 is externally connected to a pressure test device, and the protective cover 5 is movably connected to the base plate 1. During the test, the protective cover 5 covers the test piece 6 and is fixedly connected to the side limit plate 2.

[0017] The pipe burst test protection device further comprises a plug 7 , which is connected to the other end of the test piece 6 .

[0018] The bottom plate 1 is used to install and fix the entire tooling. The two side limit plates 2 are respectively installed at the two ends of the bottom plate 1. The distance between the two side limit plates 2 can be set long enough to meet the length of the longest piece of all the test pieces 6. The guide rod 3 is a track to limit the movement of the slider 4. The slider 4 can slide arbitrarily on the guide rod 3 to adapt to the adjustment of test pieces 6 of different lengths. When installing the test piece 6, one end of the test piece 6 can be fixed on the side limit plate 2 on one side first, and the slider 4 is slid to a position close to the other end of the test piece 6, and then the other end of the test piece 6 is fixed on the slider 4. One end of the test piece 6 is connected to the external pressure test equipment, and the other end is installed with a plug 7 to ensure sealing. The protective cover 5 can be flipped relative to the bottom plate 1. Before the test piece 6 is installed and prepared for the test, the protective cover 5 is flipped to cover the outside of the test environment and fixed. In this way, during the pipe burst test, the large amount of energy released at the moment of the burst will be covered by the protective cover 5 to avoid damage to external equipment and personnel.

[0019] The pipe explosion test protection device also includes a limit pin 8. The protective cover 5 is provided with a limit hole 53. The limit pin 8 is connected to the side limit plate 2. After the protective cover 5 covers the test piece 6, the limit pin 8 is connected to the limit hole 53. The limit pin 8 is used to insert the limit pin 8 into the limit holes 53 at both ends of the protective cover 5 when the protective cover 5 is closed. The two ends of the protective cover 5 are fixed and limited, which can prevent the impact force generated during the explosion from easily lifting the protective cover 5.

[0020] The protective cover 5 is divided into two side protective covers 51 and a middle protective cover 52 . The middle protective cover 52 is located between the two side protective covers 51 . The side protective covers 51 and the middle protective cover 52 are respectively hinged on the bottom plate 1 . Both side protective covers 51 are provided with limiting holes 53 .

[0021] A lock 54 and a lock handle 55 are provided on the middle protective cover 52 . The lock handle 55 is connected to the lock 54 . A lock block 11 is provided on the bottom plate 1 . When the middle protective cover 52 is closed, the lock 54 and the lock block 11 are matched and docked.

[0022] The pipe explosion test protection device further includes a protection cover handle 56 , and the side protection cover 51 and the middle protection cover 52 are respectively connected with the protection cover handle 56 .

[0023] The protective cover 5 can be split into three parts, namely, a side protective cover 51 on each side and a middle protective cover 52 in the middle. Splitting the protective cover 5 into multiple parts can avoid the problem that the protective cover 5 is too large and inconvenient to operate. The three parts correspond to different areas on the base plate 1. If one of the areas needs to be operated, it is only necessary to open or close the protective cover 5 of the corresponding area without opening the entire protective cover 5, which makes the operation more flexible.

[0024] When the side shields 51 are closed, the stop pins 8 on the two side stop plates 2 are inserted and fixed, and when the middle shield 52 is closed, the lock handle 55 is moved to make the lock 54 on the middle shield 52 dock with the lock block 11 of the bottom plate 1 and lock and fix, so as to realize the separate fixation of different parts of the shield 5. At the same time, in order to facilitate the personnel to operate the flipping of the shield 5, shield handles 56 are installed on the side shields 51 and the middle shield 52, which are convenient for personnel to hold and use force to operate.

[0025] The side panels of the protective cover 5 are provided with avoidance holes 57 for avoiding the position of the test piece 6. When the protective cover 5 is closed, its side panels will be located on the inner side of the side limit plate 2, and this position is also exactly the installation position of the test piece 6. In order to prevent the protective cover 5 from blocking or colliding with the test piece 6 after closing, the side panels of the protective cover 5 are provided with avoidance holes 57 to avoid the test piece 6.

[0026] The pipe explosion test protection device also includes a slider baffle 41, which is connected to the bottom plate 1 and parallel to the guide rod 3, and blocks one side of the slider 4. Since the guide rod 3 is a cylinder, the slider 4 is prone to lateral rotation after being installed on the guide rod 3, so that the installation position of the test piece 6 on the slider 4 cannot be aligned with the installation position of the test piece 6 on the side limit plate 2, resulting in inconvenience in installation. Therefore, the slider baffle 41 is abutted against the bottom of the slider 4, and the limit slider 4 maintains a vertical shape, so that the installation position of the test piece 6 on the slider 4 is always aligned with the installation position of the test piece 6 on the side limit plate 2.

[0027] The pipe burst test protection device also includes a hinge 9, and the protective cover 5 is hinged to the bottom plate 1 through the hinge 9. The two ends of the hinge 9 are respectively connected to the protective cover 5 and the bottom plate 1. The hinge 9 is convenient to install, and the hinge 9 can realize the flipping operation of the protective cover 5 on the base.

[0028] The operation steps of this pipe burst test protection device are as follows:

[0029] First, open the two side protective covers 51 of the protective cover 5, and then open the middle protective cover 52;

[0030] Second, the sliding block 4 is adjusted to a suitable position on the guide rod 3 according to the length of the test piece 6;

[0031] Third, install the test piece 6, one end of which is connected to the side limit plate 2 and firmly connected to the joint of the external pressure test equipment, and the other end is connected to the slider 4 and sealed by the plug 7;

[0032] Fourth, close the middle protective cover 52, and then close the two side protective covers 51;

[0033] Fifth, the limiting pins 8 are inserted into the limiting holes 53 of the two side protective covers 51 , and the locking heads 54 of the middle protective cover 52 are locked with the locking blocks 11 of the bottom plate 1 to limit the movement trajectory of the protective cover 5 .

[0034] The pipe explosion test protection device can prevent the energy released after the failure of the test piece 6 from damaging the equipment and personnel. At the same time, the joint of the guide rod 3 and the slide block 4 is matched so that the length and size of the test piece 6 are not limited.

[0035] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
