Description

Technical Field

[0001] This application relates to the field of coating testing equipment technology, specifically a portable on-site testing device for the bonding strength of waterproof coatings. Background Technology

[0002] After construction, waterproof coating needs to be applied to the exterior walls. After the waterproof coating dries, the strength of the bond between the waterproof coating and the concrete needs to be tested.

[0003] The existing testing method involves bonding and fixing the pull plate to the waterproof coating at the construction site, then connecting the adhesive strength tester to the pull plate and testing the adhesive strength of the waterproof coating by operating the adhesive strength tester. With this method, when the test surface is horizontal, the tester can be placed vertically on the test surface, which is convenient for operation. However, when the test surface is vertical, the tester needs to be placed horizontally. In this case, the staff needs to support the tester to keep it level while operating it, which is inconvenient for operation.

[0004] Therefore, this application provides a portable on-site testing device for the bonding strength of waterproof coatings to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a portable on-site testing device for the bonding strength of waterproof coatings, aiming to solve the problems mentioned in the background art, such as the requirement that the testing instrument be placed horizontally when the testing surface is vertical, which requires the operator to support the instrument to keep it level while operating it, thus making the operation of the instrument inconvenient.

[0006] To achieve the above objectives, this application provides the following technical solution: a portable on-site testing device for the bonding strength of waterproof coatings, comprising a testing machine and a pull plate disposed at the output end of the testing machine for bonding with the coating; To facilitate vertical surface testing by the testing machine: a stabilizing component is installed outside the testing machine to assist in horizontal stability; an mounting rod is installed between the stabilizing component and the testing machine for mounting the stabilizing component; a fixing block is installed on the outer wall of the testing machine for connecting the mounting rod and the testing machine; and a connecting component is installed at the end of the mounting rod for connecting with the fixing block. When it is necessary to test the adhesion strength of the coating on the vertical surface, first press the locking block, insert the insert into the slot, and under the action of the spring return force, push the locking block into the locking hole, thereby restricting the movement of the insert and fixing the mounting rod to the fixing block. Then, according to the position of the testing machine, select the usage mode of the hook claw, and by rotating the hook claw, drive the threaded rod to rotate, adjusting the distance between the hook claw and the testing machine. Whether the hook claw is hooked to the top of the wall or supported by contact with the ground, it can ensure the stability of the testing machine when it is in a horizontal testing position, thus eliminating the need for personnel to lift the testing machine and facilitating the operation of the testing machine.

[0007] Preferably, to facilitate adjustment of the distance between the hook claw and the testing machine: the stabilizing component includes a hook claw disposed outside the testing machine to assist in stabilizing the testing machine, and a threaded rod fixedly connected to the side of the hook claw facing the mounting rod for adjusting the distance between the hook claw and the testing machine. By rotating the hook claw, the threaded rod is driven to rotate, and the distance between the hook claw and the testing machine is adjusted under the combined action of the threaded groove and the threaded rod.

[0008] Preferably, to facilitate hooking onto the top of the wall: the hook of the curved claw faces the side of the testing machine, and the top of the mounting rod has a threaded groove for threaded insertion with the threaded rod. The curved shape of the hook claw hooks onto the top of the wall, thereby maintaining the stability of the testing machine.

[0009] Preferably, to facilitate support of the testing machine, the side of the hook claw away from the testing machine has anti-slip grooves to prevent slippage. As the hook claw contacts the ground, the anti-slip grooves increase the friction with the ground, thereby maintaining support for the testing machine and stabilizing it.

[0010] Preferably, to facilitate the disassembly of the mounting rod: the outer wall of the testing machine is fixedly connected to the end of the fixing block facing the testing machine, and the end of the fixing block away from the testing machine has a slot for inserting the connector, and the inner wall of the slot has a locking hole for restricting the movement of the connector. By inserting the connector into the slot, the mounting rod and the fixing block can be quickly connected. When the stabilizing component is not needed, the mounting rod and the fixing block can be separated using the connector.

[0011] Preferably, to facilitate a stable connection between the connector and the fixing block: the connector includes an insert block fixedly connected to the end of the mounting rod facing the testing machine for insertion into the slot; a locking block disposed on the side of the insert block for insertion into the locking hole; a baffle fixedly connected to one end of the locking block for limiting the movement of the locking block; and a spring disposed on one side of the baffle for pushing the baffle. The spring's restoring force pushes the locking block, maintaining the stable insertion and connection between the locking block and the locking hole, and thus maintaining the stable connection between the connector and the fixing block.

[0012] This application, through the design of stabilizers, mounting rods, fixing blocks, and connectors, allows for the following when testing the adhesion strength of coatings on vertical surfaces: first, the mounting rod is fixedly connected to the fixing block; then, depending on the position of the testing machine, the method of using the hook claw is selected; and by rotating the hook claw, the threaded rod is rotated, adjusting the distance between the hook claw and the testing machine. Whether the hook claw is hooked to the wall or supported by contact with the ground, the stability of the testing machine is ensured when it is in a horizontal testing position, thus eliminating the need for personnel to lift the testing machine and facilitating its operation.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] This embodiment provides a portable on-site testing device for the bonding strength of waterproof coatings, such as... Figure 1-6 As shown, the testing device includes a testing machine 1 and a pull plate 2 installed at the output end of the testing machine 1 for bonding with the coating. To facilitate the testing of vertical surfaces by the testing machine 1: a stabilizing component 3 is installed outside the testing machine 1 to assist in the horizontal stability of the testing machine 1; a mounting rod 4 is installed between the stabilizing component 3 and the testing machine 1 for the installation of the stabilizing component 3; a fixing block 5 is installed on the outer wall of the testing machine 1 for the connection between the mounting rod 4 and the testing machine 1; and a connecting component 6 is installed at the end of the mounting rod 4 for the connection with the fixing block 5. When it is necessary to test the adhesion strength of the coating on a vertical surface, first press the locking block 62, insert the insert block 61 into the slot, and under the restoring force of the spring 64, push the locking block 62 into the locking hole, thereby restricting the movement of the insert block 61 and fixing the mounting rod 4 to the fixing block 5. Then, according to the position of the testing machine 1, select the usage mode of the hook claw 31, and by rotating the hook claw 31, drive the threaded rod 32 to rotate, and adjust the distance between the hook claw 31 and the testing machine 1. Whether the hook claw 31 is hooked to the top of the wall or the hook claw 31 is in contact with the ground for support, it can ensure that the testing machine 1 is stable when it is in a horizontal testing position, so that the operator does not need to lift the testing machine 1, which facilitates the operation of the testing machine 1.

[0017] Furthermore, the testing machine 1 is an existing model HCTC-10T coating adhesion tester, and the pull plate 2 is an existing metal plate that is matched with the testing machine 1. The connection method between the testing machine 1 and the pull plate 2 is an existing technical means in the existing field. The pull plate 2 is glued to the coating, and then the testing machine 1 pulls the pull plate 2 to test the adhesion strength of the coating.

[0018] Specifically, to facilitate the adjustment of the distance between the hook claw 31 and the testing machine 1, the stabilizing component 3 includes a hook claw 31 disposed outside the testing machine 1 to assist in stabilizing the testing machine 1, and a threaded rod 32 fixedly connected to the side of the hook claw 31 facing the mounting rod 4 to adjust the distance between the hook claw 31 and the testing machine 1. By rotating the hook claw 31, the threaded rod 32 is driven to rotate, and the distance between the hook claw 31 and the testing machine 1 is adjusted under the combined action of the threaded groove and the threaded rod 32. Two sets of stabilizing components 3 are symmetrically arranged, located at both ends of the same side of the testing machine 1. The contact parts of the hook claw 31 and the threaded rod 32 are welded and fixed, and the outer thread of the threaded rod 32 meshes with the inner thread of the threaded groove.

[0019] More specifically, to facilitate hooking onto the top of the wall: the hook of the curved claw 31 faces the side of the testing machine 1, and the top of the mounting rod 4 has a threaded groove for threaded insertion with the threaded rod 32. The curved claw 31 hooks onto the top of the wall, thus maintaining the stability of the testing machine 1. When the testing position of the testing machine 1 is close to the top of the wall, the curved claw 31 hooks onto the top of the wall to stabilize the testing machine 1.

[0020] More specifically, to facilitate support for the testing machine 1, the hook claw 31 has anti-slip grooves 33 on the side away from the testing machine 1 to prevent slippage. When the hook claw 31 contacts the ground, the anti-slip grooves 33 increase the friction with the ground, thereby maintaining support for the testing machine 1 and stabilizing it. When the testing position of the testing machine 1 is close to the horizontal ground, the hook claw 31 does not hook onto the top of the wall; instead, the testing machine 1 can be flipped so that the part of the hook claw 31 with the anti-slip grooves 33 contacts the horizontal ground, thus providing support and stability. Simultaneously, the anti-slip grooves 33 increase the friction between the hook claw 31 and the ground, preventing slippage.

[0021] Specifically, to facilitate the disassembly of the mounting rod 4: the outer wall of the testing machine 1 is fixedly connected to the end of the fixing block 5 facing the testing machine 1. The end of the fixing block 5 away from the testing machine 1 has a slot for inserting the connector 6. The inner wall of the slot has a locking hole to restrict the movement of the connector 6. By inserting the connector 6 into the slot, the mounting rod 4 and the fixing block 5 can be quickly connected. When the stabilizer 3 is not needed, the mounting rod 4 and the fixing block 5 can be separated using the connector 6. The number and position of the fixing blocks 5 correspond to the number and position of the stabilizers 3, respectively. The contact parts of the fixing blocks 5 with the testing machine 1 are welded and fixed. The slot size matches the size of the insert 61, and the locking hole size matches the size of the locking block 62.

[0022] More specifically, to ensure a stable connection between the connector 6 and the fixing block 5: the connector 6 includes an insert 61 fixedly connected to the end of the mounting rod 4 facing the testing machine 1 for insertion into the slot; a locking block 62 disposed on the side of the insert 61 for insertion into the locking hole; a baffle 63 fixedly connected to one end of the locking block 62 for limiting its movement; and a spring 64 disposed on one side of the baffle 63 for pushing the baffle 63. The spring 64's restoring force pushes the locking block 62, maintaining the stability of the locking block 62's insertion into the locking hole, and thus maintaining the stability of the connection between the connector 6 and the fixing block 5. The insert 61 is welded and fixed to the mounting rod 4 at the contact point. The insert 61 has a cavity inside for accommodating the baffle 63 and the spring 64. The inner wall of the cavity has a hole for sliding the locking block 62. The size of the hole is the same as that of the locking hole. When the connector 6 and the fixing block 5 are installed, the insert 61 is inserted into the slot by pressing the locking block 62 first. When the locking block 62 moves to the locking hole position, the locking block 62 is inserted into the locking hole under the restoring force of the spring 64, thus realizing the quick installation of the connector 6 and the fixing block 5. When the connector 6 needs to be disassembled, the insert 61 is removed from the slot by pressing the locking block 62 out of the locking hole and moving the mounting rod 4 away from the testing machine 1, thus separating the stabilizing component 3 and the mounting rod 4 from the testing machine 1.

[0023] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
