Description

Technical Field

[0001] The invention belongs to the technical field of detection tools, and in particular relates to an on-site hard glue bonding strength detection test tool. Background Art

[0002] There are many large storage tanks in power plants, chemical plants, oil depots and other industries. In order to protect the internal surface of the tank from corrosion for a long time, large storage tanks are usually lined with a layer of rubber. This ensures that the internal surface of the tank is isolated from external factors and achieves corrosion protection without affecting the function of the tank itself.

[0003] During the long-term service of the tank, due to the continuous changes in the internal and external environments of the tank and the potential problems of the rubber material itself, the adhesion of the hard rubber will often decrease to a certain extent, and even worse, it will directly cause the rubber to peel off. This greatly affects the performance of the tank. Therefore, in order to implement the concept of "early detection and early prevention" and improve the efficiency of the use of the tank, it is necessary to regularly take effective tests on it, that is, the hard rubber bonding strength test. Usually, a test plate of the same material as the iron parts on site is made into a 200mm×100mm sample, and the surface is treated according to the construction requirements. The surface cleanliness reaches Sa2.5 and the roughness Rz is not less than 50μm. Take the same rubber plate and adhesive system as the construction site, and complete the test plate pasting process synchronously with the construction under the on-site environment. Vulcanize or vulcanize the body with the construction lining in the vulcanizer to ensure synchronous vulcanization with the lining. Then take the chisel test method to quickly test the bonding strength on the synchronous test plate after vulcanization. However, when testing the surface hard adhesive bonding strength of an already-in-service field storage tank, it is no longer possible to make a test plate under the same conditions for related testing. Only a representative sample surface can be selected locally on the field service tank for testing. Therefore, it is necessary to provide a simple and easy-to-operate, freely adjustable thickness direct-hit field testing tool for hard adhesive bonding strength, so as to facilitate the testing of the hard adhesive bonding strength of the surface of large field storage tanks. Summary of the invention

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This embodiment provides a field hard glue bonding strength testing tool, the structure of which is as follows: Figure 1 and Figure 2 As shown, it consists of a base frame 1, a striking surface 2, a transmission shaft 3, a connecting rod 4, an adjustable chisel tip 5, a rubber anti-slip film 6, a connecting shaft 7 and a chisel tip connector 8.

[0028] The base frame 1 is a rectangular plate. Figure 1 As shown, a groove is opened in the middle to form a "concave"-shaped structure, and the groove is used to install the transmission mechanism and provide support for it; Figure 1 As shown, the inner walls of both sides of the groove are provided with sliding grooves, which match the shape of the chisel tip connector 8 to provide a track for it to move forward and backward. The rubber anti-skid film 6 is adhered to the base frame with an adhesive to fix the relative position of the tool and the surface of the tank. The base frame 1 can be made of stainless steel.

[0029] The striking surface 2 is a square panel. Figure 1 As shown, it provides a point of force for striking during testing.

[0030] The transmission shaft 3, the connecting rod 4, the connecting shaft 7 and the chisel tip connector 8 form a transmission structure, which is used to convert the up-and-down movement of the striking surface 2 into forward and backward movement and transmit it to the adjustable chisel tip 5. Among them, the rotating shaft 3 is installed on the striking surface 2; the connecting shaft 4 connects the striking surface 2 and the chisel tip connector 8, the adjustable chisel tip 5 cooperates with the chisel tip connector 8, and the connecting shaft 7 connects the striking surface 2 and the base frame 1 to play a fixing role on one side and provide relative feeding force on the other side.

[0031] The shape of the transmission shaft 3 is as follows Figure 5 As shown, the groove at the top of the connecting rod 4 and the protrusion at the top of the connecting shaft 7 are passed through, so that the connecting rod 4 and the connecting shaft 7 can rotate along the transmission shaft 3.

[0032] The connecting rod 4 is a rectangular parallelepiped structure. Figure 1 As shown, a groove is formed on the top surface, which matches with the protrusion on the top of the connecting shaft 7; a through hole is formed on the two side walls of the groove along the width direction of the rectangular parallelepiped, which allows the transmission shaft 3 to pass through, so that the transmission shaft 3 can pass through the groove of the connecting rod 4 and the protrusion of the connecting shaft 7. A groove is formed on the bottom surface of the connecting rod 4, which is connected to the chisel tip connector 8 through a rotating shaft or other means, so that the chisel tip connector 8 can move forward under the push of the connecting rod 4.

[0033] The shape of the connecting shaft 7 is as follows Figure 4 As shown, a protrusion for connecting the transmission shaft 3 is provided at the top, and the size and shape of the protrusion match the groove at the top of the connecting rod 4; the bottom is connected to the groove of the base frame 1 through a rotating shaft.

[0034] The shape of the chisel tip connector 8 is as follows Figure 1 As shown, a protrusion matching the groove of the connecting rod 4 is provided at the bottom for connecting to the bottom of the connecting rod 4; a mounting groove is provided at the top for connecting the adjustable chisel tip 5; a long strip slide is provided on the side wall, which cooperates with the slide grooves on the inner walls on both sides of the groove of the base frame 1 and can move back and forth along the inner wall of the base frame 1.

[0035] The shape of the adjustable chisel tip 5 is as follows Figure 3 As shown, it includes a wedge-shaped tip and a mounting handle, which are fixed by conventional bolt and nut connection. A weak magnetic pad 5-1 is provided at the end of the mounting handle, which can not only fix the adjustable chisel tip 5 but also facilitate disassembly and replacement; the forming process of the tip adopts the cutting process in traditional material processing, which is convenient to make and easy to form. The adjustable chisel tip 5 is made of stainless steel with high hardness and strength, which is strong, not easy to break and corrosion-resistant.

[0036] like Figure 6As shown, before construction, the area to be tested needs to be pre-processed, that is, to make a sample surface of the test area, first use a knife to carve a 50mm×25mm square surface, and then use an auxiliary tool flat chisel to chisel out a 25mm×25mm opening groove 4. The remaining part is a 25mm×25mm sample surface 3.

[0037] like Figure 7 As shown, before construction, measure the thickness of the sample surface, select a suitable chisel tip, install the tool, and then put the chisel tip of the testing tool into the pre-opened groove. Stabilize the tool with your hand, and then use a hammer to knock on the knocking surface of the tool. Through the connecting rod and the connecting shaft, transfer the force to the chisel tip to separate the rubber surface from the tank surface, observe the condition of the separation surface, and test the strength of the hard glue bond.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
