Description

Technical Field

[0001] The present application relates to the technical field of geotextile detection, and in particular to a geotextile dynamic puncture detection device. Background Art

[0002] The geotextile dynamic puncture test is an important test item, which is used to simulate the ability of geotextile to resist puncture by sharp objects in actual applications. This test mainly evaluates the puncture resistance of geotextile by measuring the diameter of the hole after the geotextile is punctured by a standard steel cone dropped from a certain height.

[0003] The current dynamic puncture detection device fixes the sample by pressing the workpiece with a pressure block (for example, the Chinese utility model patent with announcement number CN205691311U discloses a dynamic load resistance test device for waterproof membrane, which adopts a pressure block to fix the workpiece). There are also other puncture detection devices that place the workpiece between two clamps and then lock the two clamps together through the cooperation of bolts and nuts to clamp the workpiece. This locking method can achieve better positioning and clamping of the workpiece than the pressure block clamping method to prevent the workpiece from moving during the puncture process. However, this method requires drilling holes in the workpiece in advance to facilitate the passage of the bolts, and the nuts need to be manually tightened on the bolts. This fixing method is more troublesome and takes a long time. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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 are within the scope of protection of this application.

[0019] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0020] Example:

[0021] See also Figure 1-4 The present application provides a technical solution: a geotextile dynamic puncture detection device, comprising a base 1 and a bracket 2 fixed on the base 1, a puncture assembly is arranged on the bracket 2, a positioning assembly 7 is arranged on the upper end of the base 1, and the positioning assembly 7 comprises a shell 71 fixed on the upper end of the base 1, a motor 74 fixed inside the shell 71, a movable seat 75 movably connected inside the shell 71, a movable groove 72 provided inside the shell 71, a support rod 77 movably inserted into the movable groove 72, a mounting seat 78 fixed on the upper end of the support rod 77, an upper chuck 79 fixed on the lower end of the mounting seat 78, a screw rod 76 screwed inside the movable seat 75 and fixed at the lower end to the output shaft of the motor 74, and a lower chuck 73 fixed on the upper end of the shell 71. The upper chuck 79 is fixed to the lower end of the mounting seat 78 by a locking bolt 8.

[0022] By setting up the above scheme, the workpiece to be tested is placed on the lower chuck 73, and the motor 74 is controlled to drive the screw rod 76 to rotate. The rotation of the screw rod 76 can drive the movable seat 75 to move downward inside the shell 71. The downward movement of the movable seat 75 can drive the mounting seat 78 and the upper chuck 79 to move downward through the support rod 77, so that the upper chuck 79 is pressed on the workpiece to achieve the clamping and positioning of the workpiece, and then the clamped workpiece is subjected to puncture detection through the puncture assembly.

[0023] See also Figure 4 In this embodiment, a movable groove 12 is opened inside the upper chuck 79, and the inner wall of the movable groove is symmetrically rotatably connected to two side plates 13, and a pressure roller 14 is rotatably connected between the two side plates 13.

[0024] By setting the above scheme, when the upper chuck 79 is pressed on the workpiece, the pressure roller 14 can be pressed on the workpiece, and when the upper chuck 79 continues to move toward the direction of the lower chuck 73, it can push the free end of the side plate 13 and the pressure roller 14 to move in the direction of the movable groove 12, and the pressure roller 14 is rotatably connected to the side plate 13. Therefore, when the upper chuck 79 descends, the workpiece can be flattened by the rotation of the pressure roller 14 and the rotation of the side plate 13, thereby ensuring that the workpiece is pressed between the upper chuck 79 and the lower chuck 73 in a taut state, thereby improving the accuracy of puncture detection.

[0025] See also Figure 2 and Figure 4 In this embodiment, a positioning flange 15 is integrally formed at the lower end of the upper chuck 79 , and a positioning groove 16 for accommodating the positioning flange 15 is formed at the upper end of the lower chuck 73 .

[0026] By setting up the above scheme, when the upper chuck 79 is pressed against the lower chuck 73, the positioning flange 15 can press the workpiece into the positioning groove 16, which can increase the contact area between the workpiece and the upper chuck 79 and the lower chuck 73, making it difficult for the workpiece to move when it is pressed between the upper chuck 79 and the lower chuck 73.

[0027] See also Figure 1 and Figure 2 In this embodiment, a avoidance groove 9 is provided at the upper end of the shell 71, and an exhaust groove 11 connected to the avoidance groove 9 is provided inside the shell 71. A hot air blower 10 is fixedly connected to one side of the shell 71, and the output end of the hot air blower 10 is connected to the exhaust groove 11.

[0028] Hot air can be outputted through the hot air blower 10, and the hot air is discharged from the exhaust slot 11 and blown onto the workpiece pressed by the upper chuck 79 and the lower chuck 73, so as to heat the workpiece, simulate the actual use temperature of the workpiece, and realize the puncture detection of the workpiece at different temperatures.

[0029] See also Figure 1 In this embodiment, the puncture assembly includes an extension frame 3 fixed to the outer surface of the bracket 2, a guide portion 4 fixed to the lower end of the extension frame 3, a puncture rod 6 movably inserted in the guide portion 4 and the extension frame 3, a positioning portion 5 fixed to the upper end of the extension frame 3 for limiting the puncture rod 6, and a conical puncture head fixed to the lower end of the puncture rod 6. The positioning portion 5 is a screw, and the puncture rod 6 is moved inside the guide portion 4 (used to guide the up and down movement of the puncture rod 6). The height of the conical puncture head can be adjusted, and the workpiece is punctured at different heights. Then, the screw is screwed to compress the puncture rod 6 to achieve the limitation of the puncture rod 6. When the precise positioning portion 5 is loosened, the conical puncture head falls freely and punctures the workpiece to achieve the puncture of the workpiece.
