Description

The test requires that silicone or resin sealing materials be applied to the sides of the test piece, and no coatings should be attached to the upper and lower surfaces of the concrete test piece. If there is any coating, it needs to be removed in advance before subsequent vacuum saturation and penetration test steps are carried out.

[0044] Please refer to Figure 1-Figure 6 , this embodiment provides an electric flux test piece sealing device 100, the electric flux test piece sealing device 100 includes a workbench 110, a clamping assembly 120 and a material discharge assembly 130;

[0045] The clamping assembly 120 is used to clamp the two ends of the specimen 10 along the axial direction thereof, and the clamping assembly 120 is rotatably connected to the workbench 110;

[0046] The material discharge assembly 130 is connected to the workbench 110 and is located directly above the test piece 10 clamped by the clamping assembly 120 and is used to guide the fluid sealing material to the outer peripheral surface of the test piece 10;

[0047] The rotation axis of the clamping assembly 120 relative to the workbench 110 and the axis of the specimen 10 are both parallel to the horizontal direction.

[0048] Please refer to Figure 1-Figure 6 The working principle of the electric flux test piece sealing device 100 is:

[0049] The function of the electric flux test piece sealing device 100 is to evenly apply the sealing material to the outer peripheral surface of the test piece 10, and the sealing material can be fluid silicone or resin;

[0050] During operation, the specimen 10 is clamped in the clamping assembly 120, and the workbench 110 corresponding to the clamping assembly 120 rotates, thereby driving the specimen 10 clamped by the clamping assembly 120 to rotate synchronously relative to the workbench 110;

[0051] Since the rotation axis of the clamping assembly 120 relative to the workbench 110 and the axis of the test piece 10 are parallel to the horizontal direction, when the clamping assembly 120 clamps the test piece 10, the two ends of the test piece 10 along the axis direction are clamped, and the peripheral surface of the test piece 10 to be coated with the sealing material is opened;

[0052] Since the material discharge assembly 130 is located directly above the specimen 10 clamped by the clamping assembly 120 and is used to guide the fluid sealing material to the outer peripheral surface of the specimen 10; therefore, as the clamping assembly 120 and the specimen 10 rotate relative to the workbench 110, different positions of the peripheral surface of the specimen 10 can be located below the material discharge assembly 130, and in this way, the sealing material can be uniformly guided to the outer peripheral surface of the specimen 10;

[0053] In summary, the electric flux test piece sealing device 100 can avoid the staff holding the test piece 10 with their hands during use through the above-mentioned structural setting, thereby preventing the sealing material from sticking to the user's hands, and by clamping the two ends of the test piece 10, it can also prevent the sealing material from sticking to the ends of the test piece 10, and further prevent the sealing material from sticking to the area outside the outer peripheral surface of the test piece 10, thereby shortening the preparation period of the test piece 10 and improving the test efficiency; in addition, since the electric flux test piece sealing device 100 adopts the rotating method of the clamping component 120 to coat the sealing material, and since the feeding component 130 is located directly above the test piece 10, the sealing material of the fluid can flow to the peripheral surface of the test piece 10 under the action of gravity, thus, through the rotation of the clamping component 120 and the corresponding structural setting, the sealing material can be quickly applied, thereby further shortening the preparation period of the test piece 10 and improving the test efficiency. At the same time, such a rotating coating method can also improve the uniformity of the sealing material, thereby reducing the adverse effects of the uniformity of the sealing material on the test structure.

[0054] It should be noted that the sealing material in the blanking component 130 is not less than the amount of material required for a single sealing, and after the corresponding sealing is completed, the test piece 10 can be taken out after the sealing material is fixed or it can be taken out simultaneously with the clamping component 120; or with the assistance of the external structure, after the corresponding sealing is completed, the test piece 10 can be taken out together with the clamping component 120.

[0055] For further information, please refer to Figure 1-Figure 6In this embodiment, when configuring the workbench 110, in order to facilitate the installation and placement of the clamping assembly 120 and the specimen 10, the workbench 110 includes a base 111 and two baffles 112, both of which are connected to the base 111, and the two baffles 112 are spaced apart to form an operation area 113 for accommodating the clamping assembly 120. It should be noted that the operation area 113 can be used for the specimen 10 and the clamping assembly 120 to facilitate the installation and removal of the specimen 10 and the clamping assembly 120.

[0056] When configuring the clamping assembly 120, it can be known from the above content that the clamping assembly 120 needs to complete the clamping work of the specimen 10, and needs to cover both ends of the specimen 10, and needs to be rotatably connected to the workbench 110. Based on this, the clamping assembly 120 in this embodiment includes a movable seat 121, a first pressing platform 122, a second pressing platform 123 and two pressing plates 124;

[0057] The movable seat 121 is rotatably connected to one of the baffles 112, the first pressing platform 122 is threadedly connected to the movable seat 121, the second pressing platform 123 is rotatably connected to the other baffle 112, and at least part of the first pressing platform 122 and the second pressing platform 123 are located in the operating area 113;

[0058] The two pressing plates 124 are respectively pressed against the two ends of the test piece 10 and are both located in the operation area 113 and between the first pressing platform 122 and the second pressing platform 123 , and are respectively pressed against the first pressing platform 122 and the second pressing platform 123 ;

[0059] The rotation axis of the movable seat 121 coincides with the rotation axis of the second pressing platform 123 , and both are parallel to the axis of the specimen 10 .

[0060] Through the above-mentioned structural arrangement, the movable seat 121 and the first Titan can be rotatably connected to the two baffles 112, so that the clamping assembly 120 can be rotatably arranged in the operating area 113, and the first press platform 122 can be moved toward or away from the second press platform 123 through the movement of the first press platform 122 relative to the movable seat 121, so that the clamping and releasing of the test piece 10 between the first press platform 122 and the second press platform 123 can be completed; in addition, this embodiment adopts a method in which the rotation axis of the movable seat 121, the rotation axis of the second press platform 123 and the axis of the test piece 10 coincide with each other, and its purpose is to ensure that during the process of synchronous rotation of the wet test piece 10 with the clamping assembly 120 relative to the workbench 110, the distance between the outer periphery of the test piece 10 and the blanking assembly 130 remains unchanged as the rotation proceeds, which is beneficial to improve the coating uniformity of the sealing material.

[0061] It is understandable that a movable first press platform 122 is provided in this embodiment, and during use, the specimen 10 and the clamping assembly 120 need to be disassembled and assembled. Therefore, the space in the operating area 113 can meet the space requirements of the aforementioned clamping assembly 120 and the specimen 10.

[0062] For further information, please refer to Figure 1-Figure 6 In this embodiment, taking the diameter of the specimen 10 as 100 mm and the height as 50 mm as an example, when configuring the pressing plate 124, in order to enable the pressing plate 124 to cover both ends of the specimen 10 and to meet the thickness of the applied sealing material of 2 mm, the diameters of the two pressing plates 124 are both larger than the diameter of the specimen 10, and the difference between the diameter of the pressing plate 124 and the diameter of the specimen 10 is greater than or equal to 4 mm. In order to facilitate the rotation of the specimen 10, the electric flux specimen sealing device 100 further includes a rotating handle 140, which is connected to the movable seat 121 or the second pressing platform 123.

[0063] Please refer to Figure 1-Figure 8 When the rotating handle 140 is operated to drive the specimen 10 to rotate, its function is to make the sealing material evenly coated on the periphery of the specimen 10. Based on this, in order to improve the quality of the coated sealing material, the present embodiment further provides a structure for making it rotate in one direction. Its function is to make the specimen 10 only rotate in one direction under the action of the rotating handle 140 during the coating of the sealing material, so as to prevent it from retreating and causing uneven coating thickness in some areas. There are many structures for achieving its one-way rotation, but the present embodiment adopts that on the basis of connecting the rotating handle 140 with the second pressing platform 123, the electric flux specimen sealing device 100 also includes a rotating disk 151, a limiting tooth disk 152, a movable limiting tooth 153 and an elastic member 154;

[0064] The rotating disk 151 is connected to the second press platform 123, and is located at the outer periphery of the second press platform 123 and is coaxial with the second press platform 123; the limiting toothed disk 152 is connected to the baffle 112 and is sleeved on the outer periphery of the rotating disk 151, and the limiting toothed disk 152 is directly opposite to the inner side of the rotating disk 151 and is configured with a plurality of oblique teeth 155 around its axis; the movable limiting teeth 153 are rotatably connected to the outer peripheral surface of the rotating disk 151, and are used to abut against the oblique teeth 155 to limit the rotation of the rotating disk 151 in one of the clockwise direction and the counterclockwise direction; the elastic member 154 is connected to the rotating disk 151 and the movable limiting teeth 153, and the elastic member 154 is used to make the movable limiting teeth 153 have a tendency to rotate toward the position abutting against the oblique teeth 155.

[0065] Therefore, through the above-mentioned structural setting, the movable limiting tooth 153 can be rotated toward the position of abutment with the bevel tooth 155 under the action of the elastic member 154, and then the rotation in one of the clockwise direction and the counterclockwise direction can be limited by the abutment between the movable limiting tooth 153 and the bevel tooth 155, but at this time, the rotation in the other direction can be carried out smoothly, thereby realizing its unidirectional rotation, preventing the specimen 10 from retreating, and improving the coating quality of the sealing material on the specimen 10.

[0066] Please refer to Figure 1-Figure 8 In this embodiment, in order to facilitate the installation and placement of the two pressing plates 124, two rotating rollers 125 are provided in the operation area 113. The two rotating rollers 125 are rotatably connected to the two baffles 112 and are used to contact the outer peripheries of the two pressing plates 124. The rotating axes of the two rotating rollers 125 are parallel to the axis of the test piece 10. Therefore, by providing the rotating rollers 125, the two pressing plates 124 can be rotated relative to the workbench 110, and the pressing plates 124 can be positioned and installed when the two pressing plates 124 are installed.

[0067] Based on the above structure settings, please refer to Figure 1-Figure 6 In this embodiment, the material discharge assembly 130 may include a frame 131 and a material discharge bin 132; the frame 131 is connected to the workbench 110, the material discharge bin 132 is connected to the frame 131, and a material discharge port 133 is provided at the lower end of the material discharge bin 132, and the material discharge port 133 is directly opposite to the test piece 10. In order to improve the uniformity of the sealing material, the length of the material discharge port 133 along the axial direction of the test piece 10 is greater than or equal to the length of the test piece 10, so that the sealing material can flow from the material discharge port 133 to the test piece 10 and evenly cover the periphery of the test piece 10 along the axial direction of the test piece 10.

[0068] Furthermore, in order to improve the uniformity of the sealing material outside the test piece 10 and avoid the situation where the local thickness is too large during use, the material discharging assembly 130 further includes a scraper 134 connected to the frame 131 or the material discharging bin 132, and the scraper 134 extends toward the test piece 10 and is spaced from the material discharging port 133. Moreover, the distance between the end of the scraper 134 facing the test piece 10 and the surface of the test piece 10 is greater than or equal to 2 mm; and taking the distance between the end of the scraper 134 facing the test piece 10 and the surface of the test piece 10 equal to 2 mm as an example, such a setting can make the sealing material on the surface of the test piece 10 not greater than 2 mm during the rotation of the test piece 10, thereby improving the uniformity of the sealing material outside the test piece 10.

[0069] The above are only preferred embodiments of the present application and are 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.
