Description

Technical Field

[0001] This invention relates to the field of building material testing technology, specifically to a stress testing device for engineering slabs. Background Technology

[0002] Building materials can be categorized into structural materials, decorative materials, and construction materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks, tiles, ceramics, glass, engineering plastics, and composite materials. Decorative materials include various coatings, paints, platings, veneers, colored ceramic tiles, and glass with special effects. For building materials, compressive strength testing is typically required, such as for stone slabs, precast concrete structural slabs, and fire-resistant steel-calcium boards.

[0003] Currently, conventional testing equipment for engineering panels has the following problems: it generally only tests the engineering panel in one direction of stress and cannot test the engineering panel in multiple directions; when the engineering panel needs to be tested in multiple directions, different testing devices are required, and it is not possible to conveniently complete the stress test in another direction on one device.

[0004] Therefore, there is an urgent need for a stress testing device for engineering sheet materials to solve the problem that conventional engineering sheet material testing equipment only tests one stress direction of the engineering sheet material. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a stress testing device for engineering sheet materials, thereby solving the problem that conventional engineering sheet material testing equipment only detects stress in one direction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stress testing device for engineering sheet metal is characterized by comprising a moving mechanism, a testing mechanism A, a testing mechanism B, and a driving mechanism. The moving mechanism includes an installation frame consisting of a support base and an arched mounting frame. The front and rear ends of the arched mounting frame are mounted on the support base. A driving mechanism is installed on the top of the arched mounting frame. The driving mechanism is used to connect a testing bracket located on the arched side of the arched mounting frame and drive the testing bracket to move vertically. Both testing mechanisms A and B are installed on the arched side of the arched mounting frame and are located below and above the testing bracket, respectively. Testing mechanism A allows building materials to be placed horizontally between testing mechanism A and the testing bracket, and the testing bracket allows building materials to be placed vertically between the testing bracket and testing mechanism B.

[0007] To optimize the above technical solution, the specific measures also include: Furthermore, the detection mechanism A includes a circular mounting rod and a movable detection plate A. The front and rear ends of the arched mounting frame are provided with vertical moving slots. The vertical circular mounting rod is set in the moving slot. The front and rear ends of the movable detection plate A are respectively slidably set in the moving slot along the circular mounting rod. A helical spring A is sleeved on the circular mounting rod. The helical spring A is connected between the lower end of the movable detection plate A and the moving slot.

[0008] Furthermore, the middle position of the active detection plate A is concave arc-shaped, and the lower end surface of the middle position is flat.

[0009] Furthermore, the detection bracket includes a first bracket, two second brackets, and two positioning protrusions. The left and right ends of the first bracket are arranged downwards to compress the building materials below. A second bracket is connected to the front and rear sides of the middle section of the first bracket. The upper end of the second bracket is used to connect to the driving mechanism. A positioning protrusion is symmetrically installed on the adjacent side of each of the two second brackets. The two positioning protrusions are used to cooperate with the upper end of the first bracket to vertically install the building materials.

[0010] Furthermore, both ends of the first bracket and the end of the positioning protrusion facing the building material are rounded.

[0011] Furthermore, the detection mechanism B includes a circular guide shaft and a movable detection plate B. The movable detection plate B is provided at the top of the arched side of the arched mounting frame. The upper end of the movable detection plate B is connected to a vertical circular guide shaft. The circular guide shaft can slide up and down through the top of the arched mounting frame. A limit ring is installed at the end of the circular guide shaft extending to the arched back side of the arched mounting frame. A helical spring B is also sleeved on the circular guide shaft. The helical spring B is connected between the upper end of the movable detection plate B and the top of the arched side of the arched mounting frame.

[0012] Furthermore, the top of the arched mounting bracket has an upwardly recessed mounting groove with a gradually decreasing width, and the movable detection plate B is located on the front and rear sides of the mounting groove sidewall, with the same inclination as the mounting groove sidewall.

[0013] Furthermore, the moving mechanism also includes a moving base and a linear electric cylinder A. The upper end of the moving base is provided with a rotating connecting seat. The bottom center of the supporting base is rotatably connected to the rotating connecting seat via a rotating shaft arranged in the front-back direction. Linear electric cylinders A are respectively provided on the moving base and on both sides of the rotating shaft. The output end of the linear electric cylinder A is used to abut against the bottom of the supporting base.

[0014] Furthermore, rollers are installed at the four corners of the bottom of the movable base.

[0015] Furthermore, it also includes a shielding mechanism. A control panel is installed on the arched back side of the arched mounting frame. A pressing bracket is fixedly installed on the side of the detection bracket, facing the control panel and extending to the left and right sides of the arched mounting frame. The shielding mechanism includes an L-shaped mounting frame and a movable shield. There are two L-shaped mounting frames, which are installed parallel to each other on both sides of the control panel. The upper ends of the long sides of the two L-shaped mounting frames are connected by a limiting baffle A, and the lower ends of the long sides are connected by a limiting baffle B. The movable shield is slidably installed on the two L-shaped mounting frames and is located between the limiting baffle A and the limiting baffle B. A helical spring C is also sleeved on the long side of the L-shaped mounting frame. The helical spring C is located between the movable shield and the limiting baffle B. Circular force-bearing rods for contacting the lower end of the pressing bracket extend from the left and right ends of the movable shield.

[0016] The beneficial effects of this invention are: This invention, through the arrangement of an installation frame, detection mechanism A, detection mechanism B, drive mechanism, and detection bracket, allows for convenient testing of building materials under two stress directions by using the drive mechanism to move the detection bracket downwards in conjunction with detection mechanism A. Then, the building materials are placed vertically on the detection bracket, and the drive mechanism moves the detection bracket upwards, simultaneously moving the building materials upwards, and in conjunction with detection mechanism B, to perform stress testing on the building materials on the detection bracket.

[0017] This invention allows workers to easily move the equipment to construction sites, facilitating outdoor testing of building materials. When the output shafts of the two front linear electric cylinders A extend, the output shafts of the two rear linear electric cylinders A retract, causing the mounting frame to automatically tilt at a certain angle. This facilitates the automatic discharge of tested building materials, saving time and improving testing efficiency. This invention enables convenient testing of building materials both horizontally and vertically, improving work efficiency. The two positioning protrusions provide positioning for vertically oriented building materials, preventing them from swaying laterally.

[0018] This invention has the advantage of reminding staff to place building materials vertically between the testing bracket and the movable testing plate B, thus avoiding the situation where building materials are forgotten to be placed; it also solves the problems of not being able to complete the force test in the other direction when the equipment is reset, requiring staff to manually remove the tested building materials, and not being able to automatically remind staff to test the other direction of the building materials.

Detailed Implementation

[0021] The invention will now be described in further detail with reference to the accompanying drawings.

[0022] As attached Figure 1 and attached Figure 2As shown, an engineering plate stress testing device according to an embodiment of the present invention is used to test building material 400. It includes a moving mechanism 100, a testing mechanism A300, a testing mechanism B500, and a driving mechanism 600. The moving mechanism 100 includes a mounting frame 102 composed of a support base and an arched mounting frame. The front and rear ends of the arched mounting frame are set on the support base. The driving mechanism 600 is installed on the top of the arched mounting frame. The driving mechanism 600 is used to connect the testing bracket 602 located on the arched side of the arched mounting frame and drive the testing bracket 602 to move vertically. The testing mechanisms A300 and B500 are both installed on the arched side of the arched mounting frame and are located below and above the testing bracket 602, respectively. The testing mechanism A300 allows the building material 400 to be placed horizontally between the testing mechanism A300 and the testing bracket 602, and the testing bracket 602 allows the building material 400 to be placed vertically between the testing bracket 602 and the testing mechanism B500.

[0023] This invention, through the arrangement of the mounting frame 102, detection mechanism A300, detection mechanism B500, drive mechanism 600, and detection bracket 602, allows for convenient detection of the building material 400 in two directions of stress during use. The drive mechanism 600 drives the detection bracket 602 downwards, cooperating with the detection mechanism A300 to perform stress testing on the building material 400 located on the detection mechanism A300. Then, the building material 400 is placed vertically on the detection bracket 602, and the drive mechanism 600 drives the detection bracket 602 upwards, simultaneously moving the building material 400 upwards. This, in conjunction with the detection mechanism B500, allows for stress testing of the building material 400 located on the detection bracket 602.

[0024] As attached Figure 3 As shown, in a specific embodiment based on the above, the detection mechanism A300 includes a circular mounting rod 301 and a movable detection plate A302. The front and rear ends of the arched mounting frame are provided with vertical moving slots. The vertical circular mounting rod 301 is disposed in the moving slot. The front and rear ends of the movable detection plate A302 are respectively slidably disposed in the moving slot along the circular mounting rod 301. A helical spring A303 is sleeved on the circular mounting rod 301. The helical spring A303 is connected between the lower end of the movable detection plate A302 and the moving slot.

[0025] Specifically, there are four circular mounting rods 301, which are distributed in pairs at both ends. The four circular mounting rods 301 are fixedly mounted on the mounting frame 102. The movable detection plate A302 is slidably mounted on the outside of the four circular mounting rods 301. There are four corresponding helical springs A303, which are sleeved on the outside of the four circular mounting rods 301.

[0026] The movable testing plate A302 has a concave arc shape in the middle, and its lower end face is flat. This facilitates the stress testing of the building material 400 in conjunction with the testing bracket 602. At the same time, the lower flat surface of the movable testing plate A302 can form support with the upper end face of the mounting frame 102.

[0027] As attached Figure 5 and attached Figure 6 As shown, in another specific embodiment based on the above, the detection bracket 602 includes a first bracket, two second brackets and two positioning protrusions 6021. The left and right ends of the first bracket are arranged downwards to compress the building material 400 below. A second bracket is connected to the front and rear sides of the middle section of the first bracket. The upper end of the second bracket is used to connect to the drive mechanism 600. A positioning protrusion 6021 is symmetrically installed on the adjacent side of the two second brackets. The two positioning protrusions 6021 are used to cooperate with the upper end of the first bracket to vertically install the building material 400.

[0028] Thus, by setting up the first bracket, two second brackets and two positioning protrusions 6021, pressure can be applied to the building material 400 below by both ends of the first bracket for detection when the drive mechanism 600 drives it to move downward, and the two positioning protrusions 6021 can cooperate with the upper end of the first bracket to vertically install the building material 400 and carry the building material 400 upward for detection when the drive mechanism 600 drives it to move upward.

[0029] In the above scheme, the drive mechanism 600 can be a linear electric cylinder B601. There are two linear electric cylinders B601. The two linear electric cylinders B601 are fixedly installed on the mounting frame 102. The second bracket of the detection bracket 602 is fixedly installed on the output shaft of the two linear electric cylinders B601 respectively.

[0030] The two ends of the first bracket and the end of the positioning protrusion 6021 facing the building material 400 are all rounded. This facilitates the assembly and disassembly of the building material 400 and reduces wear.

[0031] Specifically, when the output shafts of the two linear electric cylinders B601 extend, the detection bracket 602 drives the building material 400 to move downward. When the building material 400 meets the requirements for lateral force testing, the building material 400 will not break; when the building material 400 does not meet the requirements for lateral force testing, the building material 400 will break. When the lateral stress test of building material 400 meets the requirements, the staff then places building material 400 vertically between the testing bracket 602 and the movable testing plate B502. Next, the output shafts of the two linear electric cylinders B601 are retracted. As the output shafts of the two linear electric cylinders B601 retract, the testing bracket 602 moves building material 400 upwards. If building material 400 meets the longitudinal stress test requirements, it will not break; if it does not meet the longitudinal stress test requirements, it will break. This achieves simultaneous lateral and longitudinal testing of building material 400, improving work efficiency. The two positioning protrusions 6021 position the vertical building material 400, preventing it from swaying left and right.

[0032] As attached Figure 4 As shown, in another specific embodiment based on the above, the detection mechanism B500 includes a circular guide shaft 501 and a movable detection plate B502. The movable detection plate B502 is provided on the top of the arched side of the arched mounting frame. The upper end of the movable detection plate B502 is connected to the vertical circular guide shaft 501. The circular guide shaft 501 can slide up and down through the top of the arched mounting frame. A limit ring 503 is installed at the end of the circular guide shaft 501 extending to the arched back side of the arched mounting frame. A helical spring B504 is also sleeved on the circular guide shaft 501. The helical spring B504 is connected between the upper end of the movable detection plate B502 and the top of the arched side of the arched mounting frame.

[0033] Specifically, two circular guide shafts 501 may be provided, and the two circular guide shafts 501 are slidably mounted on the mounting frame 102. The movable detection plate B502 is fixedly mounted on the bottom of the two circular guide shafts 501. Two corresponding limiting rings 503 are provided, and the two limiting rings 503 are fixedly mounted on the top of the two circular guide shafts 501, with the bottom of the two limiting rings 503 contacting the mounting frame 102. A helical spring B504 is sleeved on the outside of the circular guide shafts 501, and the two helical springs B504 are located between the mounting frame 102 and the movable detection plate B502. The limiting rings 503 are provided to prevent the circular guide shafts 501 from slipping off.

[0034] The arched mounting bracket has an upwardly recessed mounting groove on its arched side top, with the groove gradually narrowing in width. The front and rear sides of the movable detection plate B502, close to the sidewall of the mounting groove, have the same slope as the sidewall. This allows the movable detection plate B502 to be tightly supported by the tapered mounting groove after it moves upward.

[0035] In another specific embodiment based on the above, the moving mechanism 100 further includes a moving base 101 and a linear electric cylinder A103. The upper end of the moving base 101 is provided with a rotating connecting seat. The bottom of the support base is rotatably connected to the rotating connecting seat through a rotating shaft arranged in the front-back direction. The moving base 101 is provided with linear electric cylinders A103 on both sides of the rotating shaft. The output end of the linear electric cylinder A103 is used to abut against the bottom of the support base.

[0036] Specifically, four linear electric cylinders A103 can be provided. The four linear electric cylinders A103 are fixedly mounted in pairs on the movable base 101, located on both sides of the rotating shaft. The output shafts of the four linear electric cylinders A103 are in movable contact with the bottom of the support base. Thus, by synchronously driving one linear electric cylinder A103 to retract and the other linear electric cylinder A103 to extend, the tilt of the support base can be adjusted, thereby conveniently allowing the building material 400 to slide out of the device and adjust its position.

[0037] Among them, the four corners at the bottom of the aforementioned movable base 101 are all equipped with rollers.

[0038] Therefore, rollers are installed at the bottom corners of the mobile base 101, making it convenient for staff to move the equipment to the construction site and to test the building materials 400 outdoors. Furthermore, since the mounting frame 102 is rotatably mounted on the mobile base 101 via a rotating shaft, and four linear electric cylinders A103 are fixedly mounted on the mobile base 101, with the output shafts of the four linear electric cylinders A103 in contact with the mounting frame 102, when the output shafts of the two front linear electric cylinders A103 extend, the output shafts of the two rear linear electric cylinders A103 retract, causing the mounting frame 102 to automatically tilt at a certain angle. This facilitates the automatic discharge of the tested building materials 400, saving the time required to remove the building materials 400 and improving the testing efficiency of the building materials 400.

[0039] As attached Figure 7 Appendix Figure 8 and attached Figure 9As shown, in another specific embodiment based on the above, a shielding mechanism 700 is also included. A control panel 200 is mounted on the arched back side of the arched mounting bracket. A pressing bracket 603 is fixedly mounted on the side of the detection bracket 602, facing the control panel 200 and extending to the left and right sides of the arched mounting bracket. The shielding mechanism 700 includes an L-shaped mounting bracket 701 and a movable shielding cover 702. Two L-shaped mounting brackets 701 are provided, and the two L-shaped mounting brackets 701 are installed in parallel on both sides of the control panel 200. The upper ends of the long sides of the two L-shaped mounting brackets 701 are connected to the control panel 200. The movable shield 702 is connected to the limit baffle A704 and the lower end of the long side is connected to the limit baffle B705. The movable shield 702 is slidably mounted on the two L-shaped mounting brackets 701 and is located between the limit baffle A704 and the limit baffle B705. The long side of the L-shaped mounting bracket 701 is also fitted with a helical spring C706. The helical spring C706 is located between the movable shield 702 and the limit baffle B705. The left and right ends of the movable shield 702 are respectively extended with circular force rods 703 for contacting the lower end of the pressing bracket 603.

[0040] Thus, when the output shafts of the two linear electric cylinders B601 of the drive mechanism 600 are fully extended, the pressing bracket 603 moves down synchronously with the detection bracket 602, and drives the movable shield 702 to move to the button on the control panel 200 to avoid accidental touch; and after the pressing bracket 603 moves up synchronously with the detection bracket 602, it is driven to reset by the helical spring C706 to release the restriction.

[0041] Specifically, because the pressing bracket 603 is fixedly installed on the right side of the detection bracket 602, and the movable shield 702 is slidably installed on the outside of the two L-shaped mounting brackets 701, and the two circular force-bearing rods 703 are fixedly installed on the front and rear sides of the movable shield 702; when the output shafts of the two linear electric cylinders B601 are fully extended, the detection bracket 602 drives the pressing bracket 603 to move downwards, causing the movable shield 702 to move to the button position on the control panel 200, thus shielding the button on the control panel 200. When the operator needs to press the button on the control panel 200, the operator needs to pull the movable shield 702 downwards again, thereby reminding the operator. The operator places the building material 400 vertically between the testing bracket 602 and the movable testing plate B502 to prevent the building material 400 from being forgotten. Since the bottom of the limiting baffle A704 is in contact with the movable shield 702, and the limiting baffle B705 is fixedly installed at the bottom of the two L-shaped mounting brackets 701, and the two helical springs C706 are located between the movable shield 702 and the limiting baffle B705, when the output shafts of the two linear electric cylinders B601 are fully retracted, the movable shield 702 automatically resets under the action of the two helical springs C706, ensuring that the operator does not need to pull the movable shield 702 when the building material 400 is subjected to lateral force testing.

[0042] One specific embodiment of the present invention is as follows: The detection mechanism A300 is installed on the moving mechanism 100 and is used to detect the lateral force on the building material 400; the detection mechanism B500 is installed on the moving mechanism 100 and is used to detect the longitudinal force on the building material 400; the drive mechanism 600 is installed on the moving mechanism 100 and is used to move the building material 400; a control panel 200 is installed on the right side of the moving mechanism 100, and a shielding mechanism 700 is installed on the right side of the moving mechanism 100, and the shielding mechanism 700 is located outside the control panel 200.

[0043] In use, the operator first moves the equipment to the construction materials area at the construction site. Then, the construction material 400 to be tested is placed on top of the movable testing plate A302. Next, the two linear electric cylinders B601 are activated, extending their output shafts. When the output shafts of the two linear electric cylinders B601 are extended, the testing bracket 602 moves the construction material 400 downwards. If the construction material 400 meets the requirements for lateral force testing, it will not break; if it does not meet the requirements for lateral force testing, it will break. Then the staff started the four linear electric cylinders A103. When the output shafts of the two front linear electric cylinders A103 extended, the output shafts of the two rear linear electric cylinders A103 retracted, causing the mounting frame 102 to automatically tilt at a certain angle, which facilitated the automatic discharge of the tested building materials 400, saved the time of removing the building materials 400, and improved the testing efficiency of the building materials 400. When the lateral force test of building material 400 meets the requirements, the worker then places building material 400 vertically between the testing bracket 602 and the movable testing plate B502. Then, the output shafts of the two linear electric cylinders B601 are fully retracted. As the output shafts of the two linear electric cylinders B601 retract, the testing bracket 602 moves building material 400 upwards. If building material 400 meets the longitudinal force test requirements, it will not break; if it does not meet the longitudinal force test requirements, it will break. This achieves simultaneous lateral and longitudinal testing of building material 400, improving work efficiency. The two positioning protrusions 6021 position the vertical building material 400, preventing it from swaying left and right. When the output shafts of both linear electric cylinders B601 are fully extended, the detection bracket 602 drives the pressing bracket 603 to move downwards, causing the movable shield 702 to move to the button position on the control panel 200, thus shielding the button on the control panel 200. When the operator needs to press the button on the control panel 200, the operator needs to pull the movable shield 702 downwards again, which reminds the operator to place the building material 400 vertically between the detection bracket 602 and the movable detection plate B502, preventing the building material 400 from being forgotten to be placed. When the output shafts of both linear electric cylinders B601 are fully retracted, the movable shield 702 automatically resets under the action of the two helical springs C706, ensuring that the operator does not need to pull the movable shield 702 when the building material 400 is subjected to lateral force testing.
