DETAILED DESCRIPTION
[0018] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0019] like Figure 1 As shown, a tool for rapid concrete density assessment includes a base plate 1, a water bucket 2, a bracket 3, a tensiometer 4, a storage basket 5, a lifting assembly 6, and a translation assembly 7. The water bucket 2 is mounted on the base plate 1 for translational movement via the translation assembly 7. The fixed end of the tensiometer 4 is connected to the movable end of the lifting assembly 6, and the lifting end of the tensiometer 4 is connected to the storage basket 5. The lifting assembly 6 drives the tensiometer 4 up and down, allowing the storage basket 5 to enter and exit the water bucket 2. A liquid level sensor is installed in the water bucket 2 to measure the liquid level. The tensiometer 4, with its wide measurement range, is used to measure the mass of concrete blocks, thereby achieving rapid, accurate, and efficient density measurement of full-size concrete blocks. The liquid level sensor installed in the water bucket 2 is used to measure the liquid level difference during the placement and removal of concrete blocks.
[0020] The bracket 3 includes a horizontal bracket 31 and a vertical bracket 32. One end of the horizontal bracket 31 is fixedly mounted on the top of the vertical bracket 32. The lifting assembly 6 includes a motor 61, a pulley 1 62, a pulley 2 63, and a steel wire rope 64. The pulley 1 62 and the pulley 2 63 are spaced apart at the bottom of the horizontal bracket 31. The motor 61 is mounted on the vertical bracket 32. One end of the steel wire rope 64 is connected to the motor 61, and the other end passes through the pulley 1 62 and the pulley 2 63 and is connected to the fixed end of the dynamometer 4.
[0021] The lifting assembly 6 lifts the basket 5 and concrete block and places them into the water tub 2, eliminating the need for manual handling, reducing workload, and improving testing efficiency. The specific placement and spacing of pulleys 1 62 and 2 63 are variable and should be selected based on actual needs. Preferably, pulley 1 62 is positioned near the vertical support 32, with the vertical section of the wire rope 64 parallel to the axis of the vertical support 32. Pulley 2 63 is positioned so that the basket 5 can be placed into the water tub 2 without colliding with the vertical support 32.
[0022] During the test, pure water with a density of 1.0×10^3 kg / m^3 is filled into the water tub 2. The concrete block to be tested is placed in the storage basket 5. The reading on the dynamometer 4 is read to calculate the mass m of the concrete block. The motor 61 is then driven to completely immerse the storage basket 5 and the concrete block in the water tub 2. The liquid level h1 is measured, and the density of the concrete block is calculated using the formula ρ = m / v. The volume v of the concrete block to be tested is calculated by converting the liquid levels h1 and h2. The liquid level h2 is the liquid level when the empty storage basket 5 is completely immersed in the water tub 2.
[0023] like Figure 1 and Figure 2 As shown, the storage basket 5 is provided with a support assembly 8 comprising side support plates 81, springs 82, and a bottom support plate 83. The side support plates 81 comprise a plurality of sidewalls evenly distributed within the storage basket 5 via springs 82. Each of the side support plates 81 forms a C-shaped surface that curves outward radially along the storage basket 5. The surface of each side support plate 81 facing the inside of the water tub 2 is thinly coated with a layer of rubber 811. The bottom support plate 83 comprises a cross-shaped bottom plate 1 831 and a square frame-shaped bottom plate 2 832 welded to the bottom plate 1 831. The bottom plate 2 832 is positioned centrally on the bottom plate 1 831 and comprises two layers, one inside and one outside.
[0024] In the above structure, the side support plates 81 and springs 82 in the storage basket 5 can elastically fix the irregular concrete block placed therein on the side, preventing the concrete block from suddenly tilting during the measurement process and causing errors in the measurement results; the rubber 811 coated on the side support plates 81 can prevent damage to the surface of the concrete block and affect the measurement results; the bottom support plate 83 at the bottom of the storage basket 5 is convenient for fixing the bottom of the concrete block, preventing the inertia of the water caused by the tilted placement of the concrete block from causing the water in the water bucket 2 to splash out and affect the original weight of the overflowed water, thereby ensuring the accuracy of the measurement results.
[0025] like Figure 1 As shown, the translation assembly 7 includes a slide rail 71 mounted on the base plate 1 and a slider 72 mounted on the bottom of the water tub 2 and adapted to fit within the slide rail 71. At least two sets of slide rails 71 and sliders 72 are provided. A handle 21 is provided on the sidewall of the water tub 2 to facilitate translation of the water tub 2. The translation assembly 7 allows for horizontal movement of the water tub 2, facilitating placement of the storage basket 5 for concrete blocks before testing. Once the storage basket 5 and concrete blocks are raised, the water tub 2 can be moved directly below the storage basket 5 for measurement. After measurement is complete, the concrete blocks can be easily removed. The handle 21 facilitates translation, reducing workload and improving efficiency.
[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
