Description

Technical Field

[0001] This utility model relates to the technical field of testing devices for concrete pipes, and in particular to improvements to external pressure testing devices for concrete pipes. Background Technology

[0002] The current concrete pipe manufacturing industry, such as Figure 5-6 As shown, in order to conduct an external pressure test on the produced pipe 9 to test the concrete pipe's ability to resist external loads, a three-point test method is generally adopted. The maximum linear load value of the pipe body is obtained through the transmission of mechanical pressure. The equipment mainly consists of a base 1, a column 2, an upper pressure beam 3, and a lower pressure beam 4.

[0003] When conducting an external pressure test on pipeline 9, the upper pressure beam 3 and the two side columns 2 must first be separated, then the pipeline 9 to be tested is placed in, and then the upper pressure beam 3 and the two side columns 2 are installed before the pressure test begins. However, because the upper pressure beam 3 is equipped with a hydraulic cylinder jacking device and is very heavy, each time the upper pressure beam 3 is hoisted away, then hoisted into the pipeline to be tested, and then hoisted back into place, the entire process is time-consuming, labor-intensive, and extremely inconvenient. Summary of the Invention

[0004] To address the above problems, this utility model provides an external pressure testing device for concrete pipes that can automatically "give way," facilitating the feeding and transporting of the pipe fittings to be tested without the need for frequent disassembly and reassembly of the pressure beam.

[0005] The technical solution of this utility model is as follows: it includes a base, an upper pressure beam, a lower pressure beam, and a pair of columns; a pipeline inspection station is provided on the upper part of the base;

[0006] The pair of columns are movably connected to the base via a hinge shaft. Telescopic arms are provided on the sides of the pair of columns to adjust the working posture of the pair of columns, so that the upper pressure beam and the lower pressure beam are offset from the pipeline inspection position.

[0007] Furthermore, the upper pressure beam is height-adjustable and positioned between the pair of columns.

[0008] Furthermore, a lower pressure beam is provided below the upper pressure beam, and the lower pressure beam is movably connected between a pair of columns;

[0009] The upper pressure beam and the lower pressure beam are connected by a hydraulic cylinder.

[0010] Furthermore, a diagonal bracing rod is provided on one side of the column, one end of which is connected to the side of the column via a pin, and the other end of which is fixedly connected to the foundation.

[0011] Furthermore, the pipeline inspection station consists of a pair of limiting supports.

[0012] Furthermore, the telescopic arm is a hydraulic cylinder.

[0013] This invention changes the traditional "fixed gantry" structure used for external pressure testing of concrete pipes, replacing it with a structure that allows the columns to deflect to create space for the hoisting work. A telescopic arm is used to adjust the working posture of the columns. When the pipe to be tested needs to be placed, retracting the telescopic arm causes the columns to deflect, moving the upper and lower pressure beams away from the pipe testing position, thus "making way." After the pipe is in place, the columns return to an upright position for testing. After testing, the columns deflect again to hoist the tested pipe away, completing one work cycle. This invention eliminates the need to disassemble and reassemble the upper and lower pressure beams to move the pipe in and out, saving testing time, improving testing efficiency, and significantly reducing the workload of operators.

Detailed Implementation

[0021] To make the purpose, technical solution, and beneficial technical effects of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0022] The following is in conjunction with the instruction manual appendix. Figure 1-4 The present invention will be further described below.

[0023] An external pressure testing device for concrete pipes includes a base 1, an upper pressure beam 3, a lower pressure beam 4, and a pair of columns 2; a pipe testing station 5 is located on the upper part of the base 1;

[0024] A pair of uprights 2 are movably connected to the base 1 via hinge shafts. Telescopic arms 6 are provided on the sides of each pair of uprights 2 to adjust their working posture, allowing the upper pressure beam 3 and lower pressure beam 4 to deviate from the pipeline inspection position 5. This facilitates the hoisting of the pipeline 9 to be inspected from the top.

[0025] Furthermore, the upper pressure beam 3 is height-adjustable and positioned between a pair of columns 2. Several positioning holes are provided on the columns 2 for adjusting the upper pressure beam 3 to a suitable position when testing pipes 9 of different diameters, and then fixing the upper pressure beam 3 through the positioning holes on the columns 2.

[0026] Furthermore, a lower pressure beam 4 is provided below the upper pressure beam 3, and the lower pressure beam 4 is movably connected between a pair of columns;

[0027] The upper pressure beam 3 and the lower pressure beam 4 are connected by a hydraulic cylinder. After the upper pressure beam 3 is adjusted to a suitable position, the hydraulic cylinder drives the lower pressure beam 4 to move downward, and the lower pressure beam 4 then presses the pipe 9, thereby performing external pressure detection on the pipe 9.

[0028] Furthermore, a diagonal support rod 7 is provided on one side of the column 2. One end of the diagonal support rod 7 is connected to the side of the column 2 via a pin, and the other end of the diagonal support rod 7 is fixedly connected to the foundation 10. When it is necessary to rotate the column 2, pulling out the pin will disconnect the diagonal support rod 7 from the column 2. After the pipe 9 is placed in place, the telescopic arm 6 pushes the column 2 to stand up and then inserts the pin to fix the diagonal support rod 7 to the column 2, ensuring that the column 2 is in a perpendicular position to the ground during pressure testing.

[0029] Furthermore, the pipeline inspection station 5 includes a pair of limiting supports 8 to prevent the pipeline 9 from rolling. The limiting supports 8 can be designed to be adjustable according to different pipeline specifications.

[0030] Furthermore, the telescopic boom 6 is a hydraulic cylinder.

[0031] The above are merely specific embodiments disclosed in this case, but the scope of protection of this disclosure is not limited thereto. Any modifications made by those skilled in the art to certain technical features based on the content disclosed in this case should be within the scope of protection of this case.
