Description

Technical Field

[0001] The present application relates to the technical field of impact testing, and in particular to a steel pipe anti-impact testing device. Background Art

[0002] The steel pipe impact test device is a device used to test the steel pipe's ability to resist fracture when subjected to impact loads. This device plays a key role in evaluating the toughness and strength of steel pipes, especially in key fields such as petroleum, chemical industry, energy, electricity, aerospace, etc. The strength and durability of steel pipes are directly related to the safety and reliability of the entire system.

[0003] For example, the patent with publication number CN217084455U specifically discloses a concrete impact resistance test device. The impact block is fixedly installed, and the impact block can be designed as an integral part of the guide slide. When conducting a concrete impact resistance test, the guide slide can be first raised to the required height and fixed through the slide rail, and the height is recorded through the height scale line. When the impact block makes a free fall, it can slide and guide the limit on the slide rail together with the guide slide. There is no deviation in the motion trajectory during falling, and a directional impact can be performed on the impact point of the test block below, and the test data is more accurate.

[0004] In the above patent, the impact device sets a guide component so that when the test block is subjected to an impact test, it can slide and guide the limit on the slide rail together with the guide slide plate to avoid deviation of the motion trajectory when falling, and accurately obtain the experimental data. However, since the impact block in the device is fixed, the weight of the impact block is not easy to change. When the test block needs to be subjected to impact tests of different weights, the impact block cannot be easily adjusted according to the experimental requirements, resulting in only a limited number of impact test results. This limits the comprehensiveness and representativeness of the experimental data, and may not fully reveal the performance of the steel pipe under different impact loads. Therefore, it is necessary to provide a steel pipe impact test device with freely adjustable weights to solve the above problems.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] like Figure 1-Figure 3 As shown, the present application provides a steel pipe impact test device, including a test mechanism 1, which is arranged in a steel pipe processing plant, and the test mechanism 1 includes a placement component 2, which is arranged on the ground and is used to place the steel pipe to be tested, and an impact component 4 is arranged on the top of the placement component 2, and the impact component 4 is used to perform an impact test on the steel pipe on the top of the placement component 2 to ensure that the size, shape and surface quality of the steel pipe meet the test standards;

[0034] The placement component 2 includes a fixed platform 21, which is fixedly installed on the ground. A connecting seat 22 is fixedly installed on the top of the fixed platform 21, and a slide groove 23 is opened on the top of the connecting seat 22. Two groups of supporting blocks 24 are slidably installed in the slide groove 23, and the two groups of supporting blocks 24 are mirror-set. At the same time, a triangular stopper 25 is also installed on the top of the supporting block 24. The space between the two groups of stoppers 25 forms a receiving groove, which is used to place the steel pipe and limit the movement of the steel pipe.

[0035] In order to allow the placement component 2 to accommodate steel pipes of different sizes, a motor 3 is fixedly installed on the outer side of the fixed platform 21. The output end of the motor 3 passes through the fixed platform 21 and is fixedly installed with a screw 31. In the present embodiment, the screw 31 is a bidirectional screw having two sets of opposite threads. The end of the screw 31 away from the motor 3 is rotatably connected in the fixed platform 21. At the same time, threaded holes are provided in the parts of the support blocks 24 located in the slide groove 23. The two sets of support blocks 24 are respectively installed on two different sets of threads on the screw 31 through the threaded holes, so that when the motor 3 moves, it will drive the screw 31 to rotate, so that the two sets of support blocks 24 are close to or away from each other, so as to adapt to steel pipes of different sizes.

[0036] like Figure 3-Figure 6 As shown, the impact assembly 4 includes a connecting frame 41, which is fixedly arranged on the top of the fixing platform 21 to provide a mounting base for other components. At the same time, a cylinder 42 is fixedly installed on the inner side of the top of the connecting frame 41, and a clamping claw 43 is fixedly installed on the output end of the cylinder 42. The clamping claw 43 is electrically connected to the external control device so that it can be accurately controlled by the external control system to realize automatic operation;

[0037] At the same time, a punching part 5 is also provided on the connecting frame 41, and the punching part 5 is used to apply impact to the steel pipe to achieve the expected processing effect. The punching part 5 includes a base 51, and two sets of rotating wheels 52 are installed at both ends of the base 51. At the same time, a vertical connecting groove is provided on the connecting frame 41, and the two sets of rotating wheels 52 are in contact with the connecting groove and move in the connecting groove, so that the base 51 is suitable for moving on the connecting frame 41 with the cooperation of the rotating wheels 52. At the same time, two sets of springs 44 are also provided at the bottom of the connecting groove, and the springs 44 are used to contact the base 51, so as to buffer the force generated when the base 51 falls, thereby reducing the risk of equipment damage and personal injury;

[0038] At the same time, a fixing block 53 is extended outwardly from one side of the base 51, and a ring 54 is fixedly installed on the top of the fixing block 53. The ring 54 is suitable for cooperating with the clamping jaws 43. When the clamping jaws 43 clamp the ring 54, the base 51 is lifted up as a whole under the drive of the cylinder 42, so as to realize the up and down movement of the stamping part 5.

[0039] A punch head 6 is also provided on the base 51. The punch head 6 includes a mounting seat 61. The mounting seat 61 is fixedly mounted on the bottom of the base 51. A through mounting groove 62 is provided inside the mounting seat 61. A striking head 63 is inserted into the mounting groove 62 to limit the striking head 63 at least in the lateral direction. The striking head 63 includes an impact portion at the bottom and a connecting portion at the top. The connecting portion is inserted into the mounting groove 62. The bottom of the impact portion of the striking head 63 is set to be arc-shaped for contacting with the steel pipe.

[0040] Specifically, clamping grooves are provided on both sides of the installation groove 62 , and corresponding positions on the connecting portion are provided with clamping protrusions, which are inserted into the clamping grooves to limit the impact head 63 vertically.

[0041] At the same time, in order to realize the free proportion of the weight of the stamping part 5, two groups of plug rods 7 are vertically installed on the top of the base 51, and the plug rods 7 are provided with threads. At the same time, multiple groups of counterweights 71 are arranged on the top of the base 51, and the counterweights 71 are provided with through holes adapted to the plug rods 7, so that the counterweights 71 can be quickly installed on the base 51 and kept stable under the cooperation of the through holes and the plug rods 7 during installation. At the same time, a cover plate 72 is also arranged on the base 51, and the cover plate 72 is also provided with through holes. When the counterweight 71 is installed on the top of the base 51 according to the experimental requirements, the cover plate 72 is installed on the top of the counterweight 71, and a nut is arranged on the plug rod 7, so that the counterweight 71 is firmly clamped by the cover plate 72 to avoid falling during the test;

[0042] When a stamping test is required on a steel pipe, the steel pipe is first placed in the receiving groove to fix the position of the steel pipe. The stamping part 5 is then lifted to the top of the connecting part by the clamping jaw 43. The clamping jaw 43 then releases the ring 54 to allow the stamping part 5 to fall freely under the guidance of the connecting groove. At this time, the impact head 63 will contact the steel pipe and impact the steel pipe. At this time, the impact resistance of the steel pipe can be judged by observing the damaged state of the steel pipe. The spring 44 then contacts the base 51 to buffer the force generated when the base 51 falls.

[0043] like Figure 7 As shown, in order to allow the impact head 63 to be quickly replaced after being damaged, two groups of baffles 64 are rotatably connected to the outer side of the mounting seat 61. The baffles 64 are fan-shaped, and a connecting rod is provided between the two groups of baffles 64. When one group of baffles 64 is rotated, the other group of baffles 64 will also rotate accordingly, and a torsion spring (not shown in the figure) is provided at the connection between the baffle 64 and the mounting seat 61, so that the baffle 64 will not rotate at will; the baffle 64 is suitable for returning to its position after the connecting portion is inserted into the mounting groove 62 and is in place to abut against the corresponding longitudinal side of the connecting portion to limit the impact head 63 in the longitudinal direction.

[0044] When the baffle 64 is in the initial state, the baffle 64 will cover part of the mounting groove 62, thereby making the impact head 63 installed inside the mounting groove 62 unable to move. When the impact head 63 is damaged after repeated use and needs to be replaced, one set of baffles 64 can be rotated so that the mounting groove 62 is unobstructed. At this time, the impact head 63 inside it can be quickly replaced. When the replacement is completed, the baffle 64 can be released, so that the baffle 64 can re-cover the mounting groove 62 driven by the torsion spring, so that the impact head 63 remains fixed. This arrangement allows the impact head 63 to be replaced separately without replacing the entire stamping assembly, thereby reducing spare parts costs and maintenance costs and improving the overall economy of the equipment.

[0045] In summary, the device provides a stamping portion 5 and multiple sets of counterweights 71 so that the weight of the base 51 can be freely matched according to experimental requirements. At the same time, by providing a baffle 64 and an installation slot 62, the operator can quickly replace a damaged impact head 63 through a simple rotation action without using complex tools, thereby shortening the replacement time and improving work efficiency.

[0046] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
