Description

Technical Field

[0001] This utility model relates to the technical field of building materials testing equipment, specifically a building materials compressive strength testing device. Background Technology

[0002] Steel pipes are widely used in modern construction projects. Many buildings now use steel pipes, and most modern buildings are multi-story or high-rise. This places higher demands on the compressive strength of steel pipes. If steel pipes with poor compressive strength are used, it will affect the service life of the building at best, and at worst, it will endanger people's lives.

[0003] In the process of testing the compressive strength of steel pipes, a compressive strength testing device for building materials is required. Chinese utility model patent with announcement number CN216899883U discloses a compressive strength testing device for building materials, including a worktable, legs, controller, support mechanism, bracket, cylinder, and pressure block. By setting a support mechanism on the worktable of the testing device, and setting automatic clamps at the front and rear of the support plate of the support mechanism, when not in use, the movable clamping plates of the automatic clamp expand to facilitate the placement of steel pipes into the automatic clamps. When the steel pipe is placed into the automatic clamp, the support member of the automatic clamp is pressed down by the weight of the steel pipe itself. Through the cooperation between the connecting rods, the movable clamping plates retract to clamp the steel pipe, thus automatically completing the clamping of the steel pipe.

[0004] However, the clamping action of the automatic clamp in the building materials compressive strength testing equipment of this utility model relies on the weight of the steel pipe itself to press down on the support. If the steel pipe is too light or the placement position is inaccurate, it may lead to insecure clamping and affect the accuracy of the test results. Therefore, a building materials compressive strength testing equipment is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A compressive strength testing device for building materials includes a workbench, a vertical plate fixedly connected to the top of the workbench, a horizontal plate fixedly connected to the outside of the vertical plate, and a testing mechanism disposed on the lower surface of the horizontal plate. The workbench is provided with a clamping mechanism extending to its upper surface for stably clamping steel pipes, and a shielding mechanism is disposed on the upper surface of the workbench.

[0008] The clamping mechanism includes a forward and reverse motor fixedly installed outside the worktable.

It can quickly adapt to the clamping requirements of steel pipes of different lengths. By rotating the knob to adjust the screw, the moving block and clamping block can be moved, enabling fine adjustment of the spacing between the clamping blocks.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4The compressive strength testing equipment for building materials in this embodiment includes a workbench 1, a vertical plate 2 fixedly connected to the top of the workbench 1, a horizontal plate 3 fixedly connected to the outside of the vertical plate 2, and a testing mechanism 4 disposed on the lower surface of the horizontal plate 3. The workbench 1 is provided with a clamping mechanism 5 extending to its upper surface for stabilizing the steel pipe, and a shielding mechanism 6 is provided on the upper surface of the workbench 1.

[0027] The detection mechanism 4 includes a cylinder 41 that is fixedly installed on the upper surface of the horizontal plate 3 and extends to its lower surface. A pressure sensor 42 is fixedly connected to the output end of the cylinder 41, and a pressure block 43 is fixedly connected to the bottom of the pressure sensor 42.

[0028] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the clamping mechanism 5 includes a forward and reverse motor 51 fixedly installed outside the workbench 1. A bidirectional screw 52 is fixedly connected to the output shaft of the forward and reverse motor 51. Threaded blocks 53 are threadedly connected to the left and right sides of the bidirectional screw 52. A fixing component is provided on the top of the threaded block 53.

[0029] The bidirectional screw 52 is rotatably connected to the inside of the worktable 1. The worktable 1 has a sliding groove inside that matches the threaded block 53, and the outer diameter of the threaded block 53 matches the inner diameter of the sliding groove. A limit block is fixedly connected to the bottom of the threaded block 53, and a limit rod that matches the limit block is fixedly connected inside the worktable 1. The limit block is slidably connected to the outside of the limit rod. The bidirectional screw 52 is driven to rotate by the forward and reverse motor 51, which in turn moves the threaded block 53, enabling coarse adjustment of the spacing between the fixing components and quickly adapting to the clamping requirements of steel pipes of different lengths.

[0030] Specifically, the fixing assembly includes a mounting base 54 fixedly connected to the top of the threaded block 53. An adjusting screw 55 extending outwards is threaded into the interior of the mounting base 54. Moving blocks 57 are threaded onto both the left and right sides of the adjusting screw 55. A clamping block 58 is fixedly connected to the top of each moving block 57. A knob 56 is fixedly connected to the end of the adjusting screw 55 furthest from the mounting base 54. By rotating the adjusting screw 55, the moving blocks 57 and clamping blocks 58 can be moved, allowing for fine-tuning of the spacing between the clamping blocks 58. This ensures that the clamping blocks 58 fit tightly against the surface of the steel pipe, improving the stability and reliability of the clamping, preventing the steel pipe from shaking or shifting during testing, and thus improving the accuracy of the test results.

[0031] It should be noted that the threads on both sides of the adjusting screw 55 are arranged in opposite directions. A slider extending into the mounting base 54 is fixedly connected to the bottom of the moving block 57. The mounting base 54 has a groove inside that matches the slider, and the slider and groove are slidably connected. There are two sets of fixing components, symmetrically distributed on the top of the two threaded blocks 53. The adjustment method combining the bidirectional screw 52 and the adjusting screw 55 of the clamping mechanism 5 allows the equipment to adapt to various sizes and shapes of steel pipes, eliminating the need for frequent clamp changes, improving the equipment's versatility and practicality, and reducing operating costs.

[0032] Please see Figure 1 and Figure 3 In this embodiment, the shielding mechanism 6 includes an electric push rod 61 fixedly installed on the back of the upright plate 2. A connecting lug 62 is fixedly connected to the output end of the electric push rod 61, and a storage base 63 is fixedly connected to the bottom of the connecting lug 62. A baffle 64 extending to the outside is slidably connected inside the storage base 63. The electric push rod 61 drives the storage base 63 and the baffle 64 to move, thereby achieving the function of shielding and protection. It can quickly unfold to form a protective barrier during the detection process, ensuring the safety of the operator and the bidirectional screw 52.

[0033] The storage base 63 and the baffle 64 are slidably connected to the upper surface of the bidirectional screw 52. There are two sets of baffles 64, and the storage base 63 has an internal moving opening that matches the baffle 64. A lever 65 is fixedly connected to the outside of the baffle 64, and anti-slip rubber is fixedly connected to the outside of the lever 65. By setting the baffle 64, it can be stored inside the storage base 63 and can be adjusted according to the size of the steel pipe, further enhancing the adaptability of the equipment.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the steel pipe to be tested is placed on the upper surface of the workbench 1, directly above the clamping mechanism 5. The controller starts the forward and reverse motor 51, driving the bidirectional screw 52 to rotate. The threads on the left and right sides of the bidirectional screw 52 respectively drive two threaded blocks 53 to move towards the center along the sliding groove. The fixing components on the top of the threaded blocks 53 move accordingly, and the clamping block 58 gradually approaches the steel pipe. By rotating the knob 56, the adjusting screw 55 is adjusted, causing the moving block 57 to move left and right on the adjusting screw 55, further adjusting the position of the clamping block 58 to ensure that the clamping block 58 can firmly clamp the steel pipe. The controller activates the extension and retraction of the electric push rod 61. The output end of the electric push rod 61 pushes the connecting ear 62 forward. The baffle 64 inside the storage seat 63 slides to both sides of the steel pipe via the lever 65, which serves to shield and protect the bidirectional screw 52, ​​and at the same time prevent the steel pipe from splashing or slipping during the testing process. The controller activates the extension of the cylinder 41, which drives the pressure sensor 42 and the pressure block 43 to move downward. The pressure block 43 contacts the steel pipe and applies pressure. The pressure sensor 42 monitors the applied pressure value in real time. Based on the degree of deformation of the steel pipe and the reading of the pressure sensor 42, the compressive strength of the steel pipe is determined.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field.
