Description

Technical Field

[0001] The utility model belongs to the technical field of building material detection, and in particular relates to a building material compressive strength detection device. Background Art

[0002] In the field of construction, the safety and aesthetics of construction projects are the goals that people pursue. In order to ensure the stability and reliability of the building after completion, it is necessary to use testing equipment to conduct performance tests on various construction materials before construction. Among them, the compressive resistance test of pressure-bearing building materials is crucial.

[0003] A Chinese patent with publication number CN219369410U discloses a concrete block compression resistance detection device, including a shell. The device is provided with a moving motor, gears, a top plate, a limit bar, a limit bar, a slide rail, and a strip groove device, so that during the operation of the device, the user can drive the top plate to move by the cooperation of the moving motor and the gears, and at the same time use a sealing plate to limit the top plate and seal the gap between the top plate and the shell, so as to facilitate the user to directly place concrete blocks or seal the device for detection operations, thereby reducing the user's workload, thereby improving the practicality of the device.

[0004] However, in actual use, the user of this solution can only place or take the concrete blocks through the top of the shell. Due to the limitation of the side wall of the shell, it is inconvenient for the user to take or place the concrete blocks. Moreover, when the concrete blocks are crushed in the shell by the extrusion plate, it is inconvenient for the user to clean the bottom inside the shell. That is, the above solution is not convenient for the user to take or place the concrete blocks. Utility Model Content

[0005] The utility model aims to provide a building material compressive strength testing device to solve the problem in the prior art mentioned above that it is inconvenient for users to take or place concrete blocks.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a building material compressive strength testing device, comprising

[0007] A bottom plate, a side plate with a shape of "7" is installed on the bottom plate, and a pressure detection plate is installed on the bottom plate;

[0008] The pressing mechanism includes a hydraulic cylinder and a pressing block. The hydraulic cylinder is fixed to the top of the side plate. A transmission rod is provided at the output end of the hydraulic cylinder. The pressing block is installed at the bottom of the transmission rod.

[0009] The protection component includes a protection cover and a limit rod. The cross-section of the protection cover is an inverted U-shape. The protection cover is slidably mounted on the transmission rod. The pressure block is located on the inner side of the protection cover. The limit rod is fixed to the top of the protection cover, and the upper end of the limit rod is slidably inserted with the top of the side plate.

[0010] The clamping mechanism comprises two clamping units which are symmetrical with respect to the protective cover. The clamping units are mounted on the bottom plate and are matched with the inner side of the protective cover.

[0011] The principle and effect of this technical solution:

[0012] 1. After placing the concrete block sample on the pressure detection plate on the bottom plate, the sample is clamped by the clamping unit of the clamping mechanism, and then the protective component is driven to move downward by the pressing mechanism to cover the concrete block sample and the outer side of the clamping unit. At the same time, the pressure block presses down the concrete block sample, and then the pressure detection value of the pressure detection plate is recorded, and then the pressure change of the sample during the compression test is collected, thereby playing the function of compression test.

[0013] 2. The transmission rod is driven downward by the hydraulic cylinder, thereby pressing the pressure block downward. The protective cover is slidably mounted on the protective rod. Due to the influence of its own gravity and the downward movement of the pressure block, the protective cover will also move downward until it abuts against the bottom plate. At this time, the protective cover is arranged on the clamping unit and the sample, which plays a protective role during the compression test, and the transmission rod continues to press downward, so that the pressure block can continue to press downward relative to the protective cover, thereby performing a compression test on the sample surface.

[0014] 3. By making the protective cover capable of being raised and lowered relative to the specimen placement location, the concrete block specimen will not be restricted by the protective cover when being taken and placed. Moreover, since the protective cover can be separated from the placement point of the concrete block specimen, the user can conveniently clean the placement surface, making it easy to clean the debris after the specimen is broken during the compression test.

[0015] The utility model is further configured as follows: the protection component also includes a limit block and a pressure spring, the limit block is fixed on the transmission rod and is located above the protection cover, and the pressure spring is sleeved on the transmission rod and is located between the limit block and the protection cover.

[0016] The principle and effect of this technical solution: the setting of the limit block and the pressure spring enables the hydraulic cylinder to drive the transmission rod to press down, and after the protective cover abuts against the base plate, the pressure spring can be compressed by continuing to press down the transmission rod, so that the rebound force of the pressure spring presses the protective cover against the base plate, making the position of the protective cover more stable when it is on the base plate. Compared with the protective cover itself being placed on the base plate by gravity, the method of pressing it against the base plate by the elastic force of the pressure spring is more reliable.

[0017] The utility model is further configured as follows: the protection component also includes a protection block, which is fixed on the transmission rod, located in the protection cover, and located above the pressing block.

[0018] The principle and effect of this technical solution: the setting of the protection block ensures that when the protective cover is driven downward by the elastic force of the pressure spring, it will not press against the pressure block, but press against the protection block, thereby protecting the stability of the pressure block on the transmission rod and ensuring that the use of the pressure block will not be affected by the protective cover.

[0019] The utility model is further configured as follows: the clamping unit includes a fixing plate, an electric push rod and a clamping plate, the fixing plate is fixed to the bottom plate, one end of the electric push rod is connected to a side of the fixing plate close to the protective cover, the other end of the electric push rod is connected to the clamping plate, and the clamping plate is adapted to the inner side of the protective cover.

[0020] The principle and effect of this technical solution: the electric push rod is fixed on the fixed plate, and then the electric push rod can drive the clamping plate to approach and move away from the pressure detection plate, so that the clamping plates on both sides can clamp and center the concrete block samples. At the same time, because the clamping plates are adapted to the inner side of the protective cover, the clamping plates on both sides can slide at both ends of the inner side of the protective cover and provide shielding at the same time, so that when the pressure block is pressed down, even if the concrete block is broken, it will not splash everywhere, avoiding interference and improving safety.

[0021] The utility model is further configured as follows: a control groove is opened on the bottom plate, a control board is slidably fitted in the control groove, the pressure detection board is fixed on the control board, and a handle is installed at one end of the control board away from the side wall of the side plate.

[0022] The principle and effect of this technical solution: the control panel slides in the control slot, and the control panel can drive the pressure detection panel on the control panel to move, making it convenient for users to take or place concrete blocks on the pressure detection panel, and also making it convenient for users to clean the control panel.

[0023] The utility model is further configured as follows: it also includes a locking assembly, the locking assembly includes a locking plate, a telescopic rod, a return spring and a guide rod, a accommodating cavity is vertically opened at the bottom of the control groove away from the side wall of the side plate, the guide rod and the telescopic rod are arranged in the accommodating cavity at intervals, the locking plate is slidably inserted in the accommodating cavity, the bottom of the locking plate is fixed to the top of the telescopic rod, and the upper end of the guide rod is slidably inserted into the locking plate, and the return spring is sleeved on the guide rod.

[0024] The principle and effect of this technical solution are as follows: through the arrangement of the telescopic rod, the guide rod, the return spring and the locking plate, the locking plate can be slid into the control groove under the elastic force of the return spring and the guidance of the guide rod and the accommodating cavity, thereby playing a limiting role on the control plate, so that the position of the control plate is fixed, and the locking plate can be pressed down to compress the return spring, thereby making way for the moving path of the control plate, so that the control plate can slide in the control groove, so that the control plate can be adjusted under control.

[0025] The utility model is further configured as follows: the outer shape of the locking plate is a stepped shape.

[0026] The principle and effect of this technical solution: The stepped locking plate allows the user to have more control panels when controlling the locking plate, so that the user can better apply force to the locking plate, thereby facilitating position control of the locking plate.
