Description

Technical Field

[0001] The utility model belongs to the technical field of pressure resistance detection equipment, and in particular relates to a detection device for the pressure resistance performance of a pipe. Background Art

[0002] Pipes are essential materials for construction projects, and commonly used ones include water pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. After processing, pipes must undergo certain strength and pressure tests, so it is necessary to use a pipe pressure resistance test device.

[0003] The existing patent (publication number: CN213580447U) discloses a device for detecting the pressure resistance of building pipes; it includes a base, a gantry, two groups of first pneumatic cylinders, a placement table, four groups of guide columns, multiple groups of pressurized counterweights and multiple groups of limit pneumatic rods. The gantry is fixedly arranged at the top of the base, and two groups of square mounting grooves are arranged on the base. The two groups of first pneumatic cylinders are fixedly arranged in the two groups of square mounting grooves, and the placement table is provided with an arc-shaped placement groove. The bottom ends of the four groups of guide columns are fixedly connected to the top of the base, and multiple groups of pressurized counterweights can be slid up and down on the four groups of guide columns. Multiple groups of limit pneumatic rods are respectively fixedly arranged at the left and right ends of the gantry. The gantry is provided with through holes, and the left and right ends of the pressurized counterweights are provided with limit jacks.

[0004] The above-mentioned comparative document points out that it does not require manual stacking of pressurized counterweights, reduces mechanical damage, is safe and reliable, can perform static pressure resistance testing and instantaneous impact pressure resistance testing on pipes, and is easy to operate. However, the annular placement groove of the device is small. When placing larger pipes, although the annular placement groove can place the pipe to be tested, it will still cause the outer wall of the pipe to be unable to contact the inner wall of the annular placement groove. Instead, the edges at both ends of the annular placement groove contact the pipe. This situation will directly affect the test results during the test, so a detection device for the pressure resistance performance of pipes is proposed. Utility Model Content

[0007] A frame is fixedly provided on one side of the upper end of the base plate, a threaded rod is provided on the internal thread of the upper end of the frame, the bottom end of the threaded rod is fixedly connected to a second annular extrusion block through a bearing, a cross beam is fixedly designed on the upper end of the base plate, a slide rail is fixedly provided on the side of the cross beam close to the support frame, a slider is slidably provided on the outer wall of the slide rail, and one end of the slider is fixedly connected to a limiting device through a connecting column.

[0008] Through the above scheme, the device sets up structures such as a frame, a threaded rod bearing, a second annular extrusion block, a limit device, a slide rail, a slider and a connecting column.

In this way, the device can measure the pressure of pipes of different sizes. By moving the slider, the distance between the limit device and the frame is adjusted. On the one hand, the pipe can be placed more conveniently. On the other hand, the device can measure the pressure of pipes of different lengths. By setting the first connecting plate, bolts, the second connecting plate and the first annular extrusion block, the first annular extrusion block can be replaced to complete the pressure measurement of pipes of different lengths.

[0009] Furthermore, stoppers are fixedly provided at both ends of the slide rail.

[0010] Through the above solution, the stopper is used to prevent the slider from detaching from the slide rail.

[0011] Furthermore, the limiting device is in abutment with the bottom plate.

[0012] Through the above solution, the abutment is to enable the limiting device to move.

[0013] Furthermore, a protective cover is fixedly connected to one side of the crossbeam via two rotating hinges, and an acrylic plate is fixedly arranged inside one side of the protective cover.

[0015] Furthermore, a handle is fixedly provided on one end of the threaded rod.

[0018] Through the above solution, during the process of squeezing the pipe, the pipe squeezes the second connecting block, thereby contracting the spring and causing the first connecting block to squeeze the pressure sensor, thereby obtaining the pressure borne by the pipe.

[0019] Furthermore, a display screen electrically connected to the pressure sensor is fixedly arranged on one side of the upper end of the bottom plate via a support column.

[0020] Through the above solution, the display screen is used to display the data of the pressure sensor.

[0021] Furthermore, support legs are fixedly arranged around the bottom end of the base plate.

[0022] Through the above solution, the supporting legs are used to support the height of the base plate, making it convenient for workers to operate.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The invention discloses a device for detecting the pressure resistance of a pipe. The device is provided with structures such as a frame, a threaded rod bearing, a second annular extrusion block, a limiting device, a slide rail, a slider and a connecting column. When testing the pipe, the threaded rod is rotated to drive the second annular extrusion block to move, thereby pressing and limiting the pipe.

A crossbeam 18 is fixedly designed on the upper end of the base plate 1, and a slide rail 19 is fixedly provided on the side of the crossbeam 18 close to the support frame 2. A slider 20 is slidably provided on the outer wall of the slide rail 19, and one end of the slider 20 is fixedly connected to the limiting device 13 through a connecting column 22.

[0033] See also Figure 1 , Figure 2 and Figure 3 Blocks 21 are fixedly provided at both ends of the slide rail 19, the limit device 13 is in contact with the base plate 1, a protective cover 24 is fixedly connected to one side of the cross beam 18 through two rotating hinges 23, an acrylic plate 25 is fixedly provided inside one side of the protective cover 24, a handle 12 is fixedly provided at one end of the threaded rod 9, and support legs 27 are fixedly provided around the bottom end of the base plate 1.

[0034] See also Figure 2 , Figure 3 and Figure 4A pressure sensor 14 electrically connected to the display screen 26 is fixedly arranged inside the bottom plate 1, a first connecting block 15 is fixedly arranged on the upper end of the pressure sensor 14, a spring 16 is fixedly connected to the upper end of the first connecting block 15, a second connecting block 17 is fixedly arranged on the end of the spring 16 away from the first connecting block 15, and the second connecting block 17 is on the same axis as the first annular extrusion block 7 and the second annular extrusion block 11.

[0035] See also Figure 1 and Figure 4 A display screen 26 electrically connected to the pressure sensor 14 is fixedly arranged on one side of the upper end of the base plate 1 through a support column.

[0036] In this embodiment, by setting structures such as a frame 8, a threaded rod 9, a bearing 10, a second annular extrusion block 11, a limit device 13, a slide rail 19, a slider 20 and a connecting column 22, when testing the pipe, the threaded rod 9 is rotated, thereby driving the second annular extrusion block 11 to move, and the pipe is compressed and limited. In this way, the device can measure the pressure of pipes of different sizes. By moving the slider 20, the distance between the limit device 13 and the frame 8 is adjusted. On the one hand, the pipe can be placed more conveniently. On the other hand, the device can measure the pressure of pipes of different lengths.

Therefore, there is no need for a fixed structure to fix the position of the slider 20 after the movement.

[0038] The working principle of the above embodiment is:

[0039] When the device is in use, the slider 20 is moved to adjust the distance between the limit device 13 and the frame 8. After the pipe is placed, the threaded rod 9 is rotated to drive the second annular extrusion block 11 to move, compress and limit the pipe, flip the protective cover 24, start the hydraulic push rod 3, and make the first annular extrusion block 7 descend to extrude the pipe. During the extrusion, the pipe squeezes the second connecting block 17, and the spring 16 contracts, so that the first connecting block 15 squeezes the pressure sensor 14, and the data of the pressure sensor 14 is viewed through the display screen 26.
