Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, specifically a device for measuring the thickness of precast concrete blocks. Background Technology

[0002] During concrete construction, it is usually necessary to test the concrete that enters the construction site. The tests include slump testing and test block testing. Test block testing involves making concrete blocks from the concrete to be poured for subsequent testing. When measuring the thickness of the concrete blocks, a precast concrete block thickness measuring device is required.

[0003] Existing precast concrete block thickness measuring devices measure thickness by positioning the precast concrete block on a base and then measuring it with a measuring device. However, some positioning components can only fix one concrete block at a time, resulting in low measurement efficiency when testing a large number of precast concrete blocks. Furthermore, some positioning components have a limited range of concrete block sizes that can be clamped and fixed, making it difficult to position and measure larger concrete blocks, thus limiting the application scope of the precast concrete block thickness measuring device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precast concrete block thickness measuring device, which solves the problems that some positioning components can only fix one concrete block at a time, resulting in low measurement efficiency when testing a large number of precast concrete blocks; and that some positioning components have a limited range of concrete block sizes that can be clamped and fixed, making it difficult to position and measure larger concrete blocks, thus limiting the application range of the precast concrete block thickness measuring device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a precast concrete block thickness measuring device includes a bearing unit and a measuring unit, the measuring unit is disposed on the bearing unit, the measuring unit is used to detect the thickness of the precast concrete block, and a positioning unit is disposed below the measuring unit;

[0006] The positioning unit includes:

[0015] A connecting bolt, which passes through the extrusion block and the base, and is threadedly connected to the clamping block;

[0016] A spring is disposed below the extrusion block and is used for cushioning and resetting the extrusion block.

[0017] Preferably, the clamping block is slidably connected to the base.

[0018] Preferably, sliders are provided on both sides of the extrusion block, and the sliders are slidably connected inside the clamping block.

[0019] Preferably, a cylinder is installed on the bottom end face of the base, and the output end of the cylinder is fixedly connected to the bottom end face of the connecting bolt.

[0027] This utility model discloses a device for measuring the thickness of precast concrete blocks, which has the following beneficial effects:

[0028] This precast concrete block thickness measuring device is equipped with a clamping component and a limiting component. A cylinder drives the connecting bolts to move downwards, which in turn moves the extrusion block downwards.
