Description

Technical Field

[0001] The utility model relates to the technical field of hydrostatic testing machines, in particular to a splash-proof device for a hydrostatic testing machine. Background Art

[0002] The hydrostatic testing machine is used to test the pressure resistance of materials, such as the pressure resistance failure time or the maximum pressure value of instantaneous failure of various test products such as thermoplastic pipes, composite pipes and aluminum-plastic composite pipes under long-term constant internal pressure and constant temperature. When the test product is destroyed, fragments will fly. The fragments will fly very fast under high pressure and will cause injuries to people. In order to block the flying fragments of the test product, a closed protective cover is set inside the hydrostatic testing machine to block the flying fragments of the test product, but the fragments will still be scattered all over the ground and need to be cleaned up manually one by one. Utility Model Content

[0003] The utility model aims to provide a splash-proof device for a hydrostatic testing machine, which can quickly clean up scattered test product fragments.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a splash-proof device for a hydrostatic testing machine, comprising a workbench and a sealed protective cover covering the workbench surface, wherein the area of ​​the workbench surface covered by the protective cover is divided into a lifting area and a recovery area, and a portion of the lifting area away from the recovery area can be lifted so that fragments of the test product falling thereon can slide to the recovery area, and the recovery area is concave in shape to recover the fragments of the test product.

[0005] Preferably, an observation window is provided on the protective cover for an operator to observe the working conditions inside the protective cover.

[0006] Preferably, a square groove is formed in the lifting area, a pad is embedded in the square groove, and a portion of the pad away from the recovery area can be lifted.

[0007] Preferably, an operating device is provided in the workbench, and when the operating device is operated at the beginning, the end thereof lifts the portion of the pad away from the recovery area.

[0008] Preferably, a receiving cavity is opened inside the workbench obliquely below the square groove, a top portion of the cavity is upwardly connected to a bottom portion of the square groove, and the operating device is located in the receiving cavity.

[0009] Preferably, the backing plate is hinged to the workbench via its first plate edge away from the accommodating cavity.

[0010] Preferably, a notch is provided on the side of the workbench, and the operating device includes an L-shaped member serving as a lever, with the long folded portion of the L-shaped member serving as the end to lift the portion of the pad away from the recovery area, and the short folded portion of the L-shaped member serving as the starting end to be exposed through the notch, and a pressing plate for the operator to press is provided at the exposed portion of the short folded portion. When the pressing plate is pressed, the long folded portion of the L-shaped member is driven to lift the pad upward, so that the pad rotates around the first plate edge and opens upward.

[0011] Preferably, the recovery area is located beside the first plate edge, and comprises a collecting groove forming the concave shape, wherein a removable debris box for collecting debris is embedded in the collecting groove.

[0012] Preferably, a return spring is provided to apply a return force to the short folded portion of the L-shaped member.

[0013] Preferably, one side of the protective cover close to the debris box is made into an openable protective door for people to reach in and take out objects, and the top of the side of the debris box close to the protective door is higher than the notch of the collection tank, serving as a handhold.

[0014] The beneficial effects of the utility model are:

[0015] After the test product is broken, it falls onto the recovery area. The part of the lifting area far away from the recovery area is lifted so that the test product fragments falling thereon automatically slide into the recovery area, that is, the fragments are cleaned up quickly without the need to manually clean up the scattered fragments one by one.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with specific implementation methods.

[0022] Hydrostatic testing machine Figure 1As shown. A hydraulic cylinder frame 2 is fixed on the workbench 1, and a closed protective cover 3 surrounded by four surfaces is provided in the hydraulic cylinder frame 2, and the bottom of the protective cover 3 is fixed to the workbench 1. The hydraulic cylinder (not shown in the figure) is installed on the hydraulic cylinder frame 2, and its hydraulic block is inserted into the protective cover 3. The test product this time is a pipe, and the pipe is covered in the protective cover 2 for testing. When the pressure from the hydraulic block in the cover exceeds the maximum pressure value that the pipe can withstand, the pipe will be instantly destroyed and exploded into fragments. The fragments will fall when they hit the protective cover 3 and scatter inside the protective cover 3, and will not splash outside the protective cover 3. An observation window 9 is provided on the protective cover 3, and the operator can observe the internal working conditions of the hydraulic cylinder frame 2 through the observation window 9.

[0023] Workbench 1 Figure 2 As shown, the area of ​​the tabletop covered by the protective cover 3 is divided into a lifting area and a recycling area. The lifting area is provided with a square groove 4, and a receiving chamber 7 is provided inside the workbench; the receiving chamber 7 is located obliquely below the square groove 4, and its top part is connected to the bottom part of the square groove 4 upward. A pad 5 is embedded in the square groove 4, and the pad 5 is hinged to the workbench 1 through its first plate edge 6 away from the receiving chamber 7. The recycling area is located next to the first plate edge 6, which is a concave collection groove 14 opened on the workbench, and a removable debris box 8 for collecting debris is embedded in it. An operating device is provided in the receiving chamber 7, and the operating device includes an L-shaped member as a lever, and the short folded portion 10 of the L-shaped member is exposed through the notch 11 on the side of the workbench 1, and the exposed part of the short folded portion 10b is provided with a pressing plate 12 for the operator to press; the long folded portion 10a of the L-shaped member lifts the part of the pad 5 away from the collecting groove 14. When the operator presses the pressing plate 12, the long folded portion 10a of the L-shaped member will lift the portion of the pad 5 away from the collecting groove 14 upward, so that the pad 5 rotates around the first plate edge 6 and opens upward. Figure 3 As shown, the pipe fragments will slide down to the fragment box 8, and the fragments cleaning will be completed quickly.

[0024] After the pipe fragments fall into the fragment box 8, the operator releases the pressing plate 12. Figure 4 As shown, the short folded portion 10 b of the L-shaped member is reset upward under the reset force of the reset spring, driving the long folded portion 10 a to fall back downward into the workbench 1 .

[0025] The side of the protective cover 3 close to the debris box 8 is made into an openable protective door for people to reach in and put in objects. The top of the side of the debris box 8 close to the protective door is higher than the notch of the collecting tank, which serves as a handhold 81. After the debris box 8 is full of debris, the operator opens the protective door, reaches into the cover, pinches the handhold 81 of the debris box 8 and lifts it up, and then lifts the debris box 8 from the workbench 1, so that the pipe fragments can be easily processed.

[0026] As mentioned above, the test product in this test is a pipe. Other test products may be valve bodies, cylinder barrels, etc., which are tested using the above-mentioned hydrostatic testing machine.

[0027] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
