[0036] Reference Figures 1 to 4The plastic pipe drop weight impact test device of the first aspect of the present application is applied to the plastic pipe drop weight impact test. The plastic pipe drop weight impact test device includes a base 100, a guide component 200 and a testing mechanism.

[0037] The guide component 200 is arranged on the base 100, and the guide component 200 has a vertical cavity; the test mechanism includes a test bench component 310, an impact component and a drive component 330, the test bench component 310 is arranged on the base 100 and corresponds to the lower end of the cavity of the guide component 200, the drive component 330 includes a pulley assembly 331, a traction rope 332 and a drive member 333, the pulley assembly 331 is arranged on the guide component 200 and is suitable for the traction rope 332 to be wound, and one end of the traction rope 332 is connected to the drive member 333; the impact component includes a release electromagnet assembly The upper end of the release electromagnet assembly 321 is connected to the other end of the traction rope 332, and the lower end of the release electromagnet assembly 321 is used to set the impact head assembly 322. The release electromagnet assembly 321 is suitable for adsorbing or releasing the impact head assembly 322, so that the driving member 333 drives the release electromagnet assembly 321 and the impact head assembly 322 to rise to the preset height position of the cavity, and then the impact head assembly 322 can fall freely in the cavity and act on the test sample of the test bench component 310 by releasing the release electromagnet assembly 321.

[0038] It is understandable that the setting of the pulley assembly 331 can make the impact component move accurately in the vertical direction, thereby ensuring the test accuracy under the premise of simple operation. Among them, the release electromagnet assembly 321 has two working conditions: power-on adsorption and power-off release, which ensures simple structure and easy operation, and has the advantages of easy maintenance and low cost. When testing is required, the release electromagnet assembly 321 adsorbs the impact head assembly 322, and the driving member 333 is used to make the impact head assembly 322 reach the height position required for the test, and then the release electromagnet assembly 321 is controlled to switch to the power-off release state, and the impact head assembly 322 can fall freely and act on the test sample of the test bench component 310 along the cavity of the guide component 200, thereby completing the test.

[0039] In some embodiments, the plastic pipe drop weight impact test device further includes a control device, which can control the release of the electromagnet assembly 321 and the drive member 333, thereby improving the degree of automation and meeting the test requirements.

[0040] In some embodiments, in order to ensure the test accuracy, the inner wall of the guide component 200 used to form the cavity is set to a smooth surface, so as to ensure that the impact component can fall freely in parallel and vertically.

[0041] In some embodiments, a steel wire rope is used to connect the release electromagnet, each turning point of the steel wire rope is suspended on a pulley block, and the other end is connected to a winding, which is directly connected to a motor. The height of the impact component in the guide tube can be adjusted by winding the steel wire rope by the motor.

[0042] Reference Figures 1 to 4 The plastic pipe drop hammer impact test device of the first aspect of the present application embodiment loads the test sample through the test table component 310, utilizes the pulley assembly 331 to ensure that the impact component can move vertically, utilizes the driving member 333 to control the impact component to rise to the height position to be tested, and controls the release of the electromagnet assembly 321 to enable the impact head assembly 322 to achieve free fall movement. The device has the advantages of simple structure, easy operation, easy maintenance and low cost.

[0043] In some embodiments of the present application, the plastic pipe drop hammer impact test device further includes a buffer component 400, which is disposed between the guide component 200 and the base 100. It is understandable that after the impact head assembly 322 completes the test, a reaction force will be transmitted along the base 100 to the guide component 200, and the buffer component 400 is provided to improve the test accuracy and the service life of the device.

[0044] In some embodiments, the buffer component 400 includes a buffer bracket and a buffer spring, the buffer bracket is arranged on the base 100, the guide component 200 is installed on the buffer bracket, and the buffer spring is arranged between the buffer bracket and the guide component 200. It can be understood that the buffer bracket is used to fix and limit the guide component 200, so that the guide component 200 is in a suitable state to ensure that the cavity is vertical, and the buffer spring is arranged on the buffer bracket and acts on the guide component 200, thereby playing a buffering role between the guide component 200 and the base 100.

[0045] In some other embodiments, the buffer component 400 further includes a rubber buffer foot disposed at the bottom of the base 100, or a flexible cushion layer at a specific position of the base 100, so as to achieve buffering.

[0046] In some embodiments of the present application, the testing mechanism includes an adjusting component 340, which is disposed on the base 100 and acts on the test bench component 310, and the adjusting component 340 is suitable for adjusting the relative height position of the test bench component 310. It can be understood that, under the premise that the driving member 333 can adjust the height position of the impact head assembly 322, in order to adapt to different experimental requirements and expand the adjustment range, the test bench component 310 is disposed on the adjusting component 340, and the relative height interval between the test sample on the test bench component 310 and the impact head assembly 322 is adjusted by using the adjusting component 340, so that the experiment can be completed more conveniently.

[0047] In some embodiments, the adjustment component 340 includes at least two groups of screw rods 341, an adjustment wheel 342 and a synchronous belt 343. Each screw rod 341 is arranged on the base 100 and connected to the test bench component 310. The adjustment wheel 342 is respectively connected to each screw rod 341 through the synchronous belt 343, so that the adjustment wheel 342 can synchronously drive the screw rod 341 with the belt 343 to rotate to drive the test bench component 310 to move. It can be understood that the screw rod 341 is connected to the test bench component 310 so that the screw rod 341 can drive the test bench component 310 to rise and fall when it rotates. When adjusting, the adjustment wheel 342 is manually or electrically controlled, and the rotation of the adjustment wheel 342 drives the synchronous belt 343 to move, so that each screw rod 341 moves synchronously to ensure the smooth rise and fall of the test bench component 310 and improve the adjustment accuracy.

[0048] In other embodiments, the adjusting component 340 may also be a commonly used length-adjusting structure such as a telescopic rod.

[0049] In some embodiments of the present application, the base 100 includes an upper base plate 110, a lower base plate 120 and a transparent protective plate. The upper base plate 110 and the lower base plate 120 are arranged at intervals from top to bottom. Each transparent protective plate is arranged between the upper base plate 110 and the lower base plate 120 and encloses a test space. The adjustment component 340 and the test bench component 310 are arranged in the test space. The guide component 200 is arranged on the upper base plate 110 and communicates with the test space. It can be understood that, except for the upper base plate 110 and the lower base plate 120, the other two sides and the front and back of the base 100 are made of transparent organic glass plates, which is convenient for observing the sample and the impact result. The upper base plate 110 is provided with a port connected to the guide component 200, so that the impact head assembly 322 passes through the port after coming out of the cavity of the guide component 200 to act on the test sample on the test bench component 310.

[0050] In some embodiments, the test bench component 310 includes a workbench and a sample holder for loading the test sample. In some embodiments, the sample holder is a 120° V-block with a length of 200 mm. The outer diameter of the sample ranges from 33.4 to 218.8 mm.

[0051] In some embodiments of the present application, the impact component includes a mounting seat 323, a screw 324 and a plurality of weights 325. The top of the mounting seat 323 is used to connect with the release electromagnet assembly 321. The bottom of the mounting seat 323 is provided with a screw 324. Each weight 325 is detachably inserted into the shaft of the screw 324. The impact head assembly 322 is detachably provided at the end of the screw 324. It is understandable that the mounting seat 323 is used to cooperate with the release electromagnet assembly 321 to achieve the switching between the two states of magnetic attraction or release. The screw 324 is used to selectively set the weight 325 to meet different test requirements, and finally the impact head assembly 322 is detachably installed on the screw 324.

[0052] In some embodiments, the impact head assembly 322 is a hardened hemispherical shape with a surface diameter of 25 mm, and impact heads of other diameters can also be provided according to customer requirements. The impact head assembly 322 is installed on the screw 324 through threads. The weight of the impact component without weight is: 1.25KG, and the adjustment range is: 1.25~5.25KG. There is a hole in the center of the weight that can be installed on the screw 324 and pre-tightened by two nuts. The weights are available in three specifications: 0.25KG, 0.5KG, and 1.0KG, and can be combined according to the required weight. It is also possible to configure impact head assemblies 322 and weights of different weights according to the required impact energy.

[0053] In some embodiments of the present application, the guide component 200 includes a guide tube, a guide groove 210 is provided in the guide tube, a door 220 that can be opened and closed is provided on one side of the guide groove 210, and the guide tube and the door 220 are suitable for enclosing a cavity. It can be understood that the guide groove 210 is used to cooperate with the movement of the impact head assembly 322, and the door 220 that can be opened and closed is configured to facilitate operation. When the impact head component needs to be placed, the door 220 can be opened, and after the installation is completed, the door 220 is closed to cooperate with the guide tube to enclose a cavity for testing.

[0054] In some embodiments, a scale 230 is provided on the guide groove 210 to facilitate testing. In some embodiments, the impact guide tube has a diameter of 120 mm and a length of 2.4±0.01 m, and has a vertical guide groove 210. A scale 230 is provided on one side of the guide groove 210, and the scale 230 has a graduation value of 1 mm, which is used to indicate the height of the impact hammer. There is a guide groove 210 and a door 220 baffle connected by two hinges on the side of the guide tube. The door 220 baffle can be opened to load weights on the impact component.

[0055] In some embodiments of the present application, the specific implementation method is as follows:

[0056] 1. Press the "on" button, and use the hand crank to adjust the synchronous wheel, which drives the two screw rods 341 to adjust the height of the workbench so that the impact hammer head can impact the sample after the drop hammer falls;

[0057] 2. Open the door 220 baffle, adjust the weight to get the required impact load weight, press the "up" button on the base, and release the impact hammer head that releases the electromagnet to absorb the load weight to the impact guide groove 210 scale 100 ~ 2400 ± 10mm position, then release the "up" button;

[0058] 3. Click the "drop hammer" button on the base to energize the release electromagnet, and the impact component with load weight will impact the test sample in a free fall state, completing an impact test;

[0059] For multiple tests on the same specimen, adjust the specimen placement so that the impact position is on the next impact line that is equidistant and parallel to the first line. Repeat the above operation to impact different points on the specimen.

[0060] It is understandable that by adjusting the height of the sample holder to adapt to pipes of different diameters, changing the load weight of the impact hammer, lifting it to the specified height, and releasing the hammer to free fall to impact the pipe to complete the test. By opening the door 220 baffle, the load weight can be loaded and unloaded manually, and the height of the impact hammer of the load weight can be directly adjusted by pressing the "up" or "down" button. The test machine is simple to manufacture, low in cost, and easy to operate, and the material testing operation can be achieved with minimal investment; by manually shaking the handle, the screw rod 341 can be driven to adjust the height of the bottom plate of the sample holder, fix the sample holder, and facilitate the adjustment of the sample impact position. The base is lowered to be closed and observable, which can ensure the safety of the test personnel and observe the impact of the sample during the sample impact process; the base has 4 rubber buffer machine feet, which can be used to level the test machine by adjusting the machine foot nuts. When the hammer impacts the sample, the impact force generated by the test equipment can be avoided. Direct damage to the laboratory floor, the use of rubber buffer machine feet also prevents the movement of the test machine. The instrument is easy to operate, simple, safe, easy to maintain, and low-cost. It also meets the requirements of test standards, reduces the inspection costs of manufacturing companies, and creates benefits for the companies.
