Description

Technical Field

[0001] This invention relates to the field of polyethylene anticorrosion board testing, specifically to a multi-point anchoring anticorrosion board pull-out performance testing device. Background Technology

[0002] Polyethylene sheets, also known as low-pressure high-density polyethylene, HDPE sheets, PE sheets, HDPE rods, are a type of highly crystalline, non-polar thermoplastic resin. In its original state, HDPE is milky white and, in thin sections, is somewhat translucent. Polyethylene anti-corrosion sheets are a type of anti-corrosion material.

[0003] In the application of polyethylene anticorrosive boards, their pull-out resistance is a key indicator. Traditional pull-out resistance testing devices can often only locate a certain fixed position on the board, and the position and number of fixed points cannot be adjusted, so it is impossible to evaluate the pull-out resistance of the board under different fixing conditions as needed.

[0004] Therefore, there is an urgent need for a multi-point anchoring anti-corrosion board pull-out performance testing device to solve the problem that traditional pull-out performance testing devices are not convenient for evaluating the pull-out performance of boards under different fixing conditions. Summary of the Invention

The positioning mechanism includes two support rails arranged parallel to each other on the support platform on the front and rear sides respectively. The top of the support rails on both sides is a plane, and several sleeve plates are slidably arranged on them. The sleeve plates are all connected to the vertical plate of the L-shaped plate. A vertical second bolt is threaded through the top horizontal plate of the L-shaped plate. The bottom of the second bolt is located between the top horizontal plate of the L-shaped plate and the top of the support rail. The second bolt is used for vertical displacement and pressing against the plate to be tested placed on the top plane of the support rail. The testing mechanism is arranged above the positioning mechanism and is used to test the plate to be tested fixed on the support rails on both sides.

Both ends of the horizontal plates are fixedly connected to the support platform by fixed plates. Two movable sleeves are slidably provided on the horizontal plates on both sides. The top of the movable sleeves is threaded with a vertical first bolt. The first bolt is used to move vertically to press against the surface of the horizontal plate or to loosen it. The tops of the two movable sleeves on the front and rear sides are connected to a support plate. The top of the support plate is used to connect to the support rail.

[0009] Furthermore, a positioning block is connected to the bottom end of the second bolt.

[0010] Furthermore, the detection mechanism includes a vertical plate, a first linear motor, and a second linear motor. The first linear motor is positioned above the positioning mechanism in the left-right direction, and its two ends are connected to the support platform through the vertical plate.

The bottom of the second drive seat on the second linear motor is connected to a vertical electric push rod, and the bottom of the electric push rod is connected to an electric suction cup.

[0011] Furthermore, the surface of the vertical plate is provided with an electrical control box for controlling the first linear motor and the second linear motor, and the surface of the electrical control box is provided with a display screen.

[0012] Furthermore, a tension sensor is provided between the electric suction cup and the electric push rod.

A fixed block is provided in the middle of the side of the fixed tube. A rotatable threaded rod is connected through the fixed block. The two ends of the threaded rod extend to both sides of the fixed block and are threadedly connected to a movable plate. The bottom end of the movable plate slides against the top of the tension sensor. The threaded rod is used to rotate and drive the movable plates on both sides to move closer or further apart. Each movable plate has a locking block on the side near the fixed tube. The fixed tube has corresponding through holes for the locking blocks to be inserted. The bottom of the electric push rod is connected to an insert block that can be inserted into the fixed tube. The opposite sides of the insert block have corresponding slots for the locking blocks to be inserted.

[0014] Furthermore, it also includes a heating mechanism installed on the top of the support platform. The heating mechanism includes a third linear motor and an air supply pipe. The third linear motor is installed on the support platform at the left end of the support rail in the front-back direction.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] As attached Figure 1 and attached Figure 2 As shown, an embodiment of the present invention provides a multi-point anchored anti-corrosion plate pull-out performance testing device, including a support platform 1, a positioning mechanism 2 and a testing mechanism 3 mounted thereon. The positioning mechanism 2 includes two support rails 25 arranged parallel to each other on the support platform 1 on the front and rear sides respectively. The top of the support rails 25 on both sides is a plane, and several sleeve plates 26 are slidably arranged on them respectively. The sleeve plates 26 are all connected to the vertical plates of the L-shaped plate 27. A vertical second bolt 28 is threaded through the top horizontal plate of the L-shaped plate 27. The bottom of the second bolt 28 is located between the top horizontal plate of the L-shaped plate 27 and the top of the support rail 25. The second bolt 28 is used for vertical displacement and pressing against the plate to be tested placed on the top plane of the support rail 25. The testing mechanism 3 is arranged above the positioning mechanism 2 and is used to test the plate to be tested fixed on the support rails 25 on both sides.

[0025] This invention uses a support rail 25 with a flat top, several L-shaped plates 27 slidably mounted on the support rail 25 via sleeves 26, and a second bolt 28 as fasteners. A specified number of fasteners can be selected from both sides of the support rail 25 as needed. The sleeves 26 are slid to a specified position as required, and the second bolts 28 are moved vertically to press and position the test plate placed on the top plane of the support rail 25. This allows for easy adjustment of the number and position of the fasteners on the test plate, improving the flexibility of the test plate's fixation and enabling a comprehensive evaluation of the pull-out resistance of the test plate under different fixing conditions at different fixing positions.

[0026] As attached Figure 3 As shown, in the specific embodiment one described above: The aforementioned positioning mechanism 2 also includes two horizontal plates 20 arranged parallel to each other on the support platform 1 on the left and right sides respectively. Both ends of the horizontal plates 20 are fixedly connected to the support platform 1 by fixed plates 21. Two movable sleeves 22 are slidably provided on the horizontal plates 20 on both sides respectively. The top of the movable sleeves 22 is threaded with a vertical first bolt 23. The first bolt 23 is used to move vertically to press against the surface of the horizontal plate 20 or to loosen it. The tops of the two movable sleeves 22 on the same side at the front and rear are connected to a support plate 24. The top of the support plate 24 is used to connect to the support rail 25.

[0027] In this embodiment, by setting up a horizontal plate 20, a fixed plate 21, a movable sleeve 22, a first bolt 23, and a support plate 24, it is convenient to adjust the position of the support rail 25 through the movable sleeve 22 to adjust the distance between the two support rails 25, thereby enabling the placement of test plates of different specifications; by setting up the first bolt 23, the first bolt 23 can be used to press against the horizontal plate 20 to position and fix the adjusted movable sleeve 22, thereby improving the stability of the movable sleeve 22, or it can be loosened as needed.

[0028] The bottom end of the second bolt 28 is connected to a positioning block 29. Therefore, during use, the bottom of the positioning block 29 contacts the plate to be tested, improving the stability of the fastening.

[0029] As attached Figure 4 As shown, in the second specific embodiment described above: The aforementioned detection mechanism 3 includes a vertical plate 30, a first linear motor 33, and a second linear motor 35. The first linear motor 33 is positioned above the positioning mechanism 2 in the left-right direction, and its two ends are connected to the support platform 1 through the vertical plate 30. The bottom of the first drive seat 34 on the first linear motor 33 is connected to the second linear motor 35. The first linear motor 33 and the second linear motor 35 are arranged in a cross shape. The bottom of the second drive seat 36 on the second linear motor 35 is connected to a vertical electric push rod 37, and the bottom of the electric push rod 37 is connected to an electric suction cup 38.

[0030] In this embodiment, the arrangement of the first linear motor 33, the first drive base 34, the second linear motor 35, the second drive base 36, the electric push rod 37, and the electric suction cup 38 allows for flexible adjustment of the left-right and front-back positions of the electric suction cup 38, improving its flexibility and facilitating pull-out testing of different positions of the test plate as needed. The electric suction cup 38 also facilitates the adsorption of the test plate with high adsorption stability.

[0031] The vertical plate 30 is provided with an electrical control box 31 for controlling the first linear motor 33 and the second linear motor 35. The surface of the electrical control box 31 is provided with a display screen 32.

[0032] In this embodiment, a tension sensor 39 is provided between the electric suction cup 38 and the electric push rod 37. In this embodiment, the tension sensor 39 facilitates the detection of the tension force acting on the electric suction cup 38. In the embodiment combined with the aforementioned control box 31, the detected tension force can be displayed on the screen 32, allowing the testing personnel to view the data intuitively.

[0033] As attached Figure 5 As shown, in a specific embodiment based on the above-described Embodiment 2: The aforementioned tension sensor 39 is mounted on the top of the electric suction cup 38. The top of the tension sensor 39 is connected to a fixed tube 310 with an open top. A fixed block 312 is provided in the middle of the side of the fixed tube 310. A rotatable threaded rod 313 is connected through the fixed block 312. The two ends of the threaded rod 313 extend to both sides of the fixed block 312 and are threadedly connected to a movable plate 314. The bottom end of the movable plate 314 slides against the top of the tension sensor 39. The threaded rod 313 is used to rotate and drive the movable plates 314 on both sides to move closer or further away. Each of the two movable plates 314 has a locking block 315 on the side near the fixed tube 310. The fixed tube 310 has corresponding through holes for the locking blocks 315 to be inserted. The bottom of the electric push rod 37 is connected to an insert block 311 that can be inserted into the fixed tube 310. The opposite sides of the insert block 311 have corresponding slots 316 for the locking blocks 315 to be inserted.

[0034] In this embodiment, the threaded rod 313 is supported by a fixing block 312, which facilitates the stable rotation of the threaded rod 313. By setting the threaded rod 313, the moving plate 314, and the locking block 315, the two locking blocks 315 can be driven to move closer or further apart, so that the locking blocks 315 pass through the through hole of the fixing tube 310 and engage with the locking groove 316, thereby making the fixing tube 310 and the insert block 311 firmly connected together. At the same time, it is convenient to disassemble them, and it is convenient to disassemble and replace the electric suction cup 38, for example, to replace it with a pressure detection head for pressure testing of the board to be tested, which improves the applicability of the testing device.

[0035] In the above embodiment, the threads on both sides of the threaded rod 313 have opposite directions of rotation, and knobs are connected to both the front and rear sides of the surface of the threaded rod 313. By setting the knobs, the contact area with the hand can be increased, making it easier to rotate the threaded rod 313.

[0036] As attached Figure 6 As shown, in the specific embodiment three described above: The system also includes a heating mechanism 4 mounted on the top of the support platform 1. The heating mechanism 4 includes a third linear motor 45 and a gas supply pipe 43. The third linear motor 45 is mounted on the support platform 1 at the left end of the support rail 25 in a front-to-back direction. A third drive seat 46 on the third linear motor 45 is connected to a gas supply pipe 43, which is parallel to the support rail 25 in a left-to-right direction. The gas supply pipe 43 is positioned between the top of the support rail 25 and the support platform 1, and has interconnected air outlet hoods 44 spaced apart on it. The gas supply pipe 43 is connected to a heating box 40 for heating. In this embodiment, there is a gap between the top of the support rail 25 and the support platform 1, allowing the gas supply pipe 43 to extend into and move along the third linear motor 45 in a front-to-back direction.

[0037] In this embodiment, the third linear motor 45 and the third drive seat 46 can drive the air supply pipe 43 to move back and forth, thereby driving the air outlet hood 44 to move back and forth. The heating position of the air outlet hood 44 can be adjusted to facilitate blowing air to heat different positions of the test plate, making the test plate more evenly heated and facilitating better testing of the test plate.

[0038] The bottom of the heating box 40 is connected to the support platform 1, the top of the heating box 40 is connected to the exhaust fan 41, the top of the exhaust fan 41 is connected to the telescopic hose 42, and the end of the telescopic hose 42 away from the exhaust fan 41 is connected to the air supply pipe 43.

[0039] In this embodiment, the heating chamber 40, the exhaust fan 41, the telescopic hose 42, the air supply pipe 43 and the air outlet hood 44 are arranged to deliver hot air into the inner cavity of the heating chamber 40 and blow the hot air onto the surface of the test plate to heat the test plate, thereby testing the pull-out resistance of the test plate at different temperatures.

[0040] The inner wall of the heating box 40 is provided with a heating tube 47 for heating, and a mesh plate 48 is embedded in the window on the surface of the heating box 40.

[0041] In this embodiment, the heating tube 47 can heat the air inside the heating chamber 40, and the mesh plate 48 facilitates the flow of air between the inside of the heating chamber 40 and the outside air.

[0042] One specific embodiment of the present invention is as follows: Fixing the plate to be tested: The movable support rail 25 drives the support plate 24 to move, and the support plate 24 drives the movable sleeve 22 to move, thereby adjusting the distance between the two support rails 25. At a suitable distance, the first bolt 23 is rotated to connect with the movable sleeve 22 by thread, so that the first bolt 23 abuts against the horizontal plate 20 to fix the movable sleeve 22. The plate to be tested is placed on the support rails 25 on both sides. The required number of sleeve plates 26 are selected and moved. The sleeve plates 26 drive the L-shaped plate 27, the second bolt 28 and the positioning block 29 to the required position. The second bolt 28 is rotated to connect with the L-shaped plate 27 by thread, so that the second bolt 28 drives the positioning block 29 to move downward and press the plate to be tested. Tensile detection: The electric push rod 37 is extended, which drives the insert block 311, the fixing tube 310, the tension sensor 39 and the electric suction cup 38 to move downward. The electric suction cup 38 is brought into contact with the plate to be tested and the electric suction cup 38 adsorbs the plate to be tested. The electric push rod 37 is retracted, which drives the electric suction cup 38 to move upward. The tension sensor 39 detects the tension and sends it to the electrical control box 31, and the data is displayed on the display screen 32. Adjusting the position of the electric suction cup 38: Controlling the first linear motor 33 to drive the first drive seat 34 to move left and right, thereby driving the electric suction cup 38 to move left and right, the left and right position of the electric suction cup 38 can be adjusted. By controlling the second linear motor 35 to drive the second drive seat 36 to move back and forth, the front and back position of the electric suction cup 38 can be adjusted, which facilitates adsorption and detection at different positions of the plate to be tested. Heating: The heating tube 47 is controlled to heat the air inside the heating chamber 40. The hot air is delivered by the exhaust fan 41. The hot air inside the heating chamber 40 passes through the exhaust fan 41, the telescopic hose 42, the air supply pipe 43 and the air outlet hood 44 in sequence, and finally blown onto the surface of the test plate to heat the test plate. The temperature of the test plate can be changed. In use, the third linear motor 45 is controlled to drive the third drive seat 46 to move back and forth. The third drive seat 46 drives the air supply pipe 43 and the air outlet hood 44 to move back and forth, thereby adjusting the position of the air outlet hood 44 to facilitate heating different parts of the test plate.
