Description
Technical Field
[0001] This application relates to the technical field of steel structure testing devices, specifically a rapid testing device for the quality of building materials. Background Technology
[0002] With the rapid development of the construction industry and the continuous innovation of building materials, the quality and safety of construction projects have received increasing attention from all sectors of society. As an indispensable and important component of construction projects, the quality of building materials directly affects the safety, durability, and service life of the project.
[0003] According to Chinese patent publication number CN221594578U, a building steel structure quality inspection device utilizes clamping components to facilitate the clamping and positioning of steel structures of different sizes by workers, thereby improving the inspection efficiency. Furthermore, the transparent plastic observation window not only allows workers to observe the inspection process but also provides protection for them.
[0004] When performing pressure tests on steel structure materials, this solution mainly utilizes the clamp body and pressure block in the clamping assembly to clamp and fix the steel structure materials. However, this clamping structure is not widely applicable and can only clamp flat, conventional steel plates. When encountering round tube-type steel structure materials, the shape of the round tube is not relatively flat compared to the steel plate, and the use of pressure block fixation cannot guarantee the stability during the pressure test.
[0005] Therefore, this application provides a rapid testing device for the quality of building materials to solve the above problems. Utility Model Content
[0006] This application provides a rapid testing device for the quality of building materials, which aims to solve the problem mentioned in the background art that the clamping device on the existing steel structure quality testing device is not stable enough when clamping round tube steel structure materials.
[0007] To achieve the above objectives, this application provides the following technical solution: a rapid testing device for the quality of building materials, comprising a base and a box mounted on the base, wherein a pressure testing device and a fixing rod are provided inside the box, a servo motor is provided at the lower end of the base, an adjustment device for connecting to the output end of the servo motor is provided inside the base, a box door is hinged to the box, and a clamping mechanism is provided on the fixing rod.
[0008] The clamping mechanism includes a support plate fitted onto a fixed rod. A vertical plate is fixedly installed on the upper end of the support plate. A first movable groove is opened on the vertical plate. An assembly plate is fitted onto the vertical plate. Pressing blocks are symmetrically arranged on the assembly plate. A threaded rod is rotatably connected to one end of the back of the vertical plate. A limit rod is fixedly installed on the other end of the back of the vertical plate. The assembly plate and the threaded rod are threaded together. The vertical movement of the assembly plate is controlled by the linkage between the threaded rod and the limit rod. Combined with the multi-point clamping of the pressing blocks, the round tube can be quickly positioned and stably fixed, improving the detection accuracy and operation efficiency.
[0009] The assembly plate is movably sleeved with the limiting rod, and a first gripping wheel is fixedly installed at the upper end of the threaded rod. The limiting rod and the threaded rod cooperate to eliminate the risk of offset when the assembly plate moves, ensuring linear and precise clamping action.
[0010] Several strip plates are installed at equal intervals on the support plate.
[0011] A bidirectional lead screw is rotatably connected to the assembly plate. A second gripping wheel is fixedly installed at one end of the bidirectional lead screw. A second movable groove is provided on the assembly plate. A slider for connecting with the pressing block is provided on the second movable groove. The slider and the bidirectional lead screw are threaded together. The bidirectional lead screw drives the symmetrical slider to move synchronously, so as to realize the balanced distribution of the symmetrical clamping force of the pressing block and avoid detection errors caused by uneven force on the round tube.
[0012] The slider is symmetrically equipped with limiting protrusions for sliding connection with the second movable groove. The lower end of each slider is fixedly connected to a fixing seat. The pressing block has a round hole and the pressing block is fixedly connected to the fixing seat by bolts.
[0013] A calibration plate is symmetrically mounted on the pressing block, and an arc-shaped groove is provided at the lower end of the pressing block, with toothed blocks evenly distributed in the arc-shaped groove.
[0014] The testing device involves manually rotating the first grip wheel to bring the assembly plate close to the steel tube placed on the strip plate. Then, the positions of the two sliders are adjusted so that the pressing block below the sliders clamps the outer surface of the tube. Once the sliders can no longer be adjusted, the assembly plate is moved downwards until it can no longer move. At this point, the tube is in a state of being pressed and fixed by the pressing block. The pressure testing device can then be used to apply pressure to the tube for testing.
[0015] When construction workers inspect steel round pipes, the arc-shaped grooves on the pressing blocks of this testing device can be customized according to different specifications of round pipes. Corresponding pressing blocks can be installed for different specifications of round pipes, making the entire device more widely applicable. Attached Figure Description

[0023] 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.
[0024] This embodiment provides a rapid testing device for the quality of building materials, such as... Figure 1-5 As shown, the detection device includes a base 1 and a housing 2 mounted on the base 1. The housing 2 is equipped with a pressure detection device 4 and a fixing rod 6. A servo motor 5 is installed at the lower end of the base 1. An adjustment device for connecting to the output end of the servo motor 5 is installed inside the base 1. A door 3 is hinged on the housing 2. A clamping mechanism 7 is installed on the fixing rod 6.
[0025] The clamping mechanism 7 includes a support plate 71 fitted on the fixed rod 6. A vertical plate 73 is fixedly installed on the upper end of the support plate 71. A first movable groove 731 is opened on the vertical plate 73. An assembly plate 75 is fitted on the vertical plate 73. Pressing blocks 78 are symmetrically arranged on the assembly plate 75. A threaded rod 74 is rotatably connected to one end of the back of the vertical plate 73. A limit rod 742 is fixedly installed on the other end of the back of the vertical plate 73. The assembly plate 75 and the threaded rod 74 are threadedly connected.
[0026] The adjustment device inside the base 1 is existing technology, and the existing technology structure in the comparative scheme is adopted. The vertical plate 73 is mainly used to connect the assembly plate 75. The first movable groove 731 opened on the vertical plate 73 is used to adjust the vertical position of the assembly plate 75. When the operator is pressing and clamping the round tube, he only needs to manually rotate the first grip wheel 741 to make the assembly plate 75 close to the steel round tube placed on the strip plate 72, and then adjust the position of the two sliders 77 so that the pressing block 78 below the sliders 77 clamps the outer surface of the round tube until the sliders 77 can no longer be adjusted. Then, the assembly plate 75 is moved downward until it can no longer be moved. The round tube is then in a state of being pressed and fixed by the pressing block 78. At this time, the pressure detection device 4 can be used to apply pressure to the round tube for detection.
[0027] The assembly plate 75 is movably sleeved with the limiting rod 742, and the upper end of the threaded rod 74 is fixedly installed with the first gripping wheel 741.
[0028] The limiting rod 742 is inserted into the assembly plate 75, which improves the stability of the assembly plate 75 when the threaded rod 74 is rotated to adjust its position.
[0029] Several strip plates 72 are installed at equal intervals on the support plate 71.
[0030] There is a certain gap between several strip plates 72, which is mainly used to prevent the round tube from shaking significantly when it is pre-placed. The distance between the strip plates 72 makes it easier for workers to use the pressing block 78 to clamp the round tube.
[0031] A double-acting lead screw 76 is rotatably connected to the assembly plate 75. A second gripping wheel 761 is fixedly installed at one end of the double-acting lead screw 76. A second movable groove 762 is provided on the assembly plate 75. A slider 77 for connecting with the pressing block 78 is provided on the second movable groove 762. The slider 77 and the double-acting lead screw 76 are threaded together.
[0032] A slider 77 is mounted on each of the opposite threaded surfaces at both ends of the bidirectional lead screw 76. After the second gripping wheel 761 rotates, the two sliders 77 can move closer or further away from each other with the pressing block 78, so that the pressing block 78 can clamp the round tube more accurately.
[0033] The slider 77 is symmetrically equipped with limiting protrusions 773 for sliding connection with the second movable groove 762. The lower end of the slider 77 is fixedly connected with a fixed seat 771. The pressing block 78 has a round hole 781. The pressing block 78 and the fixed seat 771 are fixedly connected by bolts 772.
[0034] The limiting protrusion 773 installed on the slider 77 is slidably installed with the second movable groove 762 opened on the assembly plate 75. When the second grip wheel 761 rotates, it can make the slider 77 more stable when moving. The fixed seat 771 installed at the lower end of the slider 77 is mainly used for the detachable installation of the pressing block 78.
[0035] A calibration plate 782 is symmetrically installed on the pressing block 78. An arc-shaped groove is opened at the lower end of the pressing block 78, and toothed blocks 783 are evenly distributed in the arc-shaped groove.
[0036] When the construction worker inspects the steel round pipe, the arc-shaped groove on the pressing block 78 can be customized according to the different specifications of the round pipe. The corresponding pressing block 78 can be installed for the round pipe of different specifications. The toothed block 783 installed on the arc-shaped groove of the pressing block 78 is used to increase the friction when in contact with the surface of the round pipe, thereby improving the stability during the inspection.
[0037] In use, manually rotate the first grip wheel 741 to bring the assembly plate 75 close to the steel tube placed on the strip plate 72, then adjust the position of the two sliders 77 so that the pressing block 78 below the sliders 77 clamps the outer surface of the tube until the sliders 77 can no longer be adjusted. Then move the assembly plate 75 downwards until it can no longer move. The tube is then in a fixed state by the pressing block 78. At this point, the pressure detection device 4 can be used to apply pressure to the tube for detection.
[0038] 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.
