[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] At least one embodiment of the utility model provides an adjustment device for an impacted object in an impact test, and the adjustment device 100 includes a base 1, a carrier 2, a support 3 and a plurality of adjustment members 4. The carrier 2 has a bearing surface for bearing the impacted object. The support 3 is connected to the base 1, and the support 3 is configured to support the carrier 2. The carrier 2 is rotatable relative to the support 3 to adjust the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located. The plurality of adjustment members 4 are arranged on the carrier 2, and the plurality of adjustment members 4 are configured to adjust the position of the impacted object. In this way, by utilizing the base 1, the carrier 2 and the support 3 to form an impact angle adjustment assembly, before performing the impact test, the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located is adjusted by rotating the carrier 2 relative to the support 3, thereby achieving the adjustment of the impact angle of the impacted object. In addition, by arranging multiple sets of position adjustment parts 4 on the object carrier 2, and using the object carrier 2 and the multiple sets of position adjustment parts 4 to form an impact position adjustment assembly, before the impact test, the position of the impacted object can be adjusted according to the position required for the impact test through the mutual cooperation between the multiple sets of position adjustment parts 4. The adjustment device provided by the embodiment of the utility model has a simple structure and is easy to disassemble. When performing an impact test, the impact position and impact angle can be adjusted according to the size and required angle of the impacted object, thereby realizing the lifting of the impacted object by a crane, avoiding the safety hazards of manual installation, and can quickly, safely, conveniently and accurately install the impacted object.

[0020] As long as the multiple sets of positioning members 4 can adjust the position of the impacted object, they can be set according to the structure of the impacted object. On this basis, the embodiment of the utility model does not specifically limit the structural design and quantity of the multiple sets of positioning members 4. The structural design of the positioning member 4 is described below with examples in combination with several specific embodiments.

[0021] In at least one embodiment of the present invention, Figure 1 and 2As shown, the positioning member 4 includes a screw 41, a spring 42 and a positioning plate 43. The object carrier 2 and the positioning plate 43 are connected and limited by the screw 41. The spring 42 is passed through the screw 41, and the spring 42 is configured to adjust the distance between the positioning plate 43 and the frame of the object carrier 2 according to the structure of the object to be impacted. In this way, the screw 41 is used to limit the position between the object carrier 2 and the positioning plate 43, and the elastic force of the spring 42 can be used to clamp the object to be impacted, so as to adjust the impact position.

[0022] Each adjustment plate 43 is provided with one or more screws 41, and the number of screws 41 corresponds to the number of springs 42. Figure 1 As shown, each adjustment plate 43 is provided with two screw rods 41 and two springs 42. In this way, the adjustment accuracy of the position of the adjustment plate 43 is higher, which is more conducive to fixing the position of the impacted object.

[0023] The number of the multiple sets of positioning members 4 can be 2 sets, 3 sets, or 4 sets, etc. For example, in some embodiments, Figure 1 As shown, the number of the multiple sets of positioning members 4 is 2 sets, which are respectively located on the left and right sides of the object carrier 2. In this way, the positioning member 4 can move left and right along the object carrier 2, so as to fix the object to be impacted according to its width and adjust the left and right positions of the object to be impacted. The operation is very convenient, and the efficiency of the impact test can be effectively improved, the time can be shortened, and the safety of the workers can be ensured, which has a good application and promotion value.

[0024] For example, the two adjustment plates 43 in the two sets of adjustment members 4 can move left and right along the object carrier 2 , and the spring 42 can adjust the distance between the adjustment plates 43 and the frame of the object carrier 2 according to the width of the impacted object.

[0025] After adjusting the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located, the position of the carrier 2 can be fixed by using the base 1, or the position of the carrier 2 can be fixed by using the support member 3. On this basis, the embodiment of the utility model does not specifically limit the method for fixing the position of the carrier 2.

[0026] The following describes the method of fixing the position of the object carrier 2 with reference to several specific embodiments.

[0027] In at least one embodiment of the present invention, Figure 1As shown, the base 1 is provided with a plurality of bosses 1a parallel to each other. The adjusting device 100 also includes a first pin shaft 5 and at least one angle adjustment rod 6. One end of the angle adjustment rod 6 is connected to the carrier 2 through the first pin shaft 5, and when the other end of the angle adjustment rod 6 is clamped at different boss 1a positions, the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located is different. In this way, by clamping the position of the angle adjustment rod 6 with any one of the multiple bosses 1a provided on the base 1, the position of the carrier 2 is limited, and by adjusting the angle adjustment rod 6 to clamp at different boss 1a positions, the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located is adjusted, so that the angle adjustment rod 6 of the adjusting device for adjusting the impacted object in the impact test cooperates with the multiple bosses 1a on the base 1 to play a role in angle adjustment.

[0028] In at least one embodiment of the present invention, Figure 3 As shown, the end of the angle adjustment rod 6 is provided with a right-angle hook 6a matched with the boss 1a. In this way, according to the angle required for the impact test, the right-angle hook 6a at the end of the angle adjustment rod 6 connected to the carrier 2 can be clamped at the corresponding boss 1a position on the base 1, thereby playing a role in adjusting the impact angle of the impacted object. The right-angle hook design is conducive to improving the stability of the carrier 2 during the impact test.

[0029] Figure 1 The working principle of the adjustment device of the illustrated embodiment is as follows: before conducting the impact test, the adjustment plate 43 is first pushed to both sides, and the object to be impacted is placed on the object carrier 2. In the process of loosening the adjustment plate 43, the adjustment plate 43 is clamped to the object to be impacted by the elastic force of the spring 42, thereby adjusting the impact position. According to the angle required for the impact test, the right-angle hook 6a at the end of the angle adjustment rod 6 connected to the object carrier 2 is clamped at the corresponding multi-stage boss position on the base 1, thereby adjusting the impact angle of the object to be impacted.

[0030] In at least one embodiment of the utility model, a plurality of bosses parallel to each other are provided on the base 1. When the end of the carrier 2 closest to the base 1 is clamped at different boss positions, the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located is different. In this way, any one of the plurality of bosses provided on the base 1 can be directly used to clamp the end of the carrier 2 closest to the base 1, and the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located can be adjusted by adjusting the end of the carrier 2 closest to the base 1 to be clamped at different boss positions.

[0031] In at least one embodiment of the utility model, the base 1 is provided with a plurality of grooves parallel to each other, and the groove is configured to accommodate the end of the carrier 2 closest to the base 1. When the end of the carrier 2 closest to the base 1 is stuck at different groove positions, the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located is different. In this way, any one of the plurality of grooves provided on the base 1 can be used to clamp the end of the carrier 2 closest to the base 1, and the angle between the bearing surface of the carrier 2 and the plane where the base 1 is located can be adjusted by adjusting the end of the carrier 2 closest to the base 1 to be stuck at different groove positions.

[0032] One end of the support member 3 can be rigidly fixed to the base 1, for example, by welding or bolting, and one or both ends of the support member 3 can also be rotatable relative to the base 1, as long as the support member 3 can support the carrier 2. On this basis, the embodiment of the utility model does not specifically limit the structural design of the support member 3. Below, the structural design of the support member 3 is illustrated in combination with several specific embodiments.

[0033] In at least one embodiment of the present invention, the support member 3 includes a door-shaped vertical support member 31, and the adjustment device further includes a second pin shaft 7. One end of the object carrier 2 is rotatably connected to the crossbeam of the vertical support member through the second pin shaft 7. In this way, the object carrier 2 is rotatably connected to the crossbeam of the vertical support member through the second pin shaft 7, thereby realizing that the object carrier 2 can rotate relative to the support member 3.

[0034] In at least one embodiment of the present invention, the support member 3 further includes at least one oblique support member 32 connected to the vertical support member 31. A triangular structure is formed between the vertical support member 31, the oblique support member 32 and the base 1. In this way, by utilizing the triangular structure formed between the vertical support member 31, the oblique support member 32 and the base 1, it is beneficial to improve the stability of the adjustment device during the impact test, thereby improving the accuracy of the test result of the impact test.

[0035] For example, a vertical support member 31 and an oblique support member 32 are pre-welded on the base 1 , and two ends of the oblique support member 32 are respectively welded to the base 1 and the vertical support member 31 to form a stable triangular structure.

[0036] In some embodiments, the vertical support member 31 and the oblique support member 32 may also be provided with one or more cross beams to further improve the stability of the support member 3. In other embodiments, the support member 3 may also only include the oblique support member 32, and the oblique support member 32 directly supports the object carrier 2.
