Description

Technical Field

[0001] The utility model belongs to the technical field of storage devices, and in particular relates to a concrete core sample storage device. Background Art

[0002] Concrete core samples are used to test the strength and durability of concrete buildings. Conventional concrete core samples have a diameter of 150mm or 100mm, but in many cases, the diameter of the core sample can also reach other sizes. After coring, the core sample is transported to the laboratory for analysis. During the transportation process, a storage device is required to place the core sample. Existing storage devices can generally only hold core samples of a single size, and the applicable scenarios are relatively limited.

[0003] A Chinese patent with publication number CN214268573U discloses a core storage box, which includes a cylinder and a clamping assembly. The clamping assembly includes a pressure shoe and a plurality of compression springs. The compression springs are located between the pressure shoe and the inner wall of the cylinder. The above scheme places the core between multiple clamping assemblies, and uses the elastic force of the compression springs to push the pressure shoes to press against the core together, thereby achieving the purpose of storing cores of different lengths.

[0004] The above scheme can also be used to store concrete core samples after adjustment. However, when the above scheme is in use, there are gaps between the pressure tiles, and the compression spring is prone to twisting and bending. When external force shakes the storage box, the core sample is easy to escape from the gap between adjacent pressure tiles and collide with the side wall of the cylinder, thereby causing damage, resulting in poor support effect of the above scheme on the core sample. Utility Model Content

[0005] The utility model aims to provide a concrete core sample storage device to solve the problem of poor supporting effect on the core sample in the above-mentioned solution.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A concrete core sample storage device comprises a cylinder, a support plate and a lifting mechanism, wherein the cylinder has an inner cavity, the top of the cylinder is open and a top cover is inserted therein, the support plate is slidably embedded in the inner cavity, a support rod is slidably penetrated through the top of the support plate along its axial direction, a plurality of pressure shoes are also slidably penetrated through the top of the support plate along the circumference of the support rod, the bottoms of the pressure shoes are rotatably connected to connecting rods, one end of the connecting rods is rotatably connected to the bottom of the support rods, the lifting mechanism is arranged in the inner cavity and can drive the support plate to move longitudinally.

[0008] The principle and effect of this technical solution:

[0009] Put the concrete core sample into the inner cavity and place it on the top of the support rod. Under the action of gravity, the concrete core sample pushes the support rod downward, and then drives the pressure shoe to move towards the direction close to the concrete core sample through the connecting rod until each pressure shoe is pressed against the concrete core sample. The placement height of the concrete core sample is adjusted through the lifting mechanism so that its upper edge is lower than the upper edge of the cylinder. Finally, the top cover is inserted into the open position so that the bottom of the top cover is in contact with the top of the concrete core sample.

[0010] Through the above arrangement, the concrete core sample automatically pushes the support rod to drive the pressure tile to press the concrete core sample, and the placement height of the concrete core sample is adjusted by the lifting mechanism so that the top cover abuts against the concrete core sample, so that the utility model can clamp concrete core samples of various sizes and avoid twisting of the pressure tile, thereby solving the problem of poor support effect on the core sample in the above scheme.

[0011] In the utility model, the lifting mechanism includes a screw rod and a driving assembly. The screw rods are provided in two numbers and are respectively rotatably penetrated through the bottom of the cylinder. The left and right ends of the support plate are respectively fitted on the two screw rods, and the driving assembly can drive the two screw rods to rotate.

[0012] In the utility model, the driving assembly includes a base plate, a main gear and a slave gear. The slave gear is provided in two numbers and is respectively fixedly sleeved on the two screw rods below the cylinder. The base plate is rotatably sleeved on the bottom of the cylinder. The main gear is fixedly provided on the top of the base plate and is respectively connected to the two slave gears.

[0013] The principle and effect of this technical solution:

[0014] After placing the concrete core sample on the top of the support rod, the pressure pad automatically clamps the side wall of the concrete core sample, rotates the bottom plate to rotate the main gear, and then drives the two slave gears and the screw to rotate. The support plate moves longitudinally to the appropriate height as the screw rotates.

[0015] Through the above settings, the purpose of adjusting the placement height of the concrete core sample is achieved.

[0016] In the utility model, the lifting mechanism is configured as a telescopic rod, the upper and lower ends of the telescopic rod are respectively fixedly connected to the support plate and the bottom of the cylinder, and the number of the telescopic rods is two and symmetrically arranged on both sides of the support rod.

[0017] The principle and effect of this technical solution:

[0018] After placing the concrete core sample on the top of the support rod, the pressure tile automatically clamps the side wall of the concrete core sample and continues to push the concrete core sample to compress the telescopic rod so that the support plate moves longitudinally to the appropriate height, thereby achieving the purpose of adjusting the placement height of the concrete core sample.

[0019] In the utility model, the lifting mechanism is configured as a first compression spring, and the first compression spring is disposed between the support plate and the bottom of the cylinder.

[0020] The principle and effect of this technical solution:

[0021] After placing the concrete core sample on the top of the support rod, the pressure shoe automatically clamps the side wall of the concrete core sample and continues to push the concrete core sample to compress the first compression spring so that the support plate moves longitudinally to a suitable height, thereby achieving the purpose of adjusting the placement height of the concrete core sample.

[0022] In the utility model, a connecting plate is arranged at the bottom of the support rod, and a tension spring is sleeved between the support plate and the connecting plate. Through the above arrangement, the support rod is automatically reset after the concrete core sample is taken out, thereby pushing each pressure tile to reset, which is convenient for the next storage work.

[0023] In the utility model, a groove is formed at the bottom of the top cover, a top plate is slidably embedded in the groove, and a second compression spring is arranged between the top plate and the top wall of the groove. Through the above arrangement, the top cover can be prevented from over-extruding the concrete core sample and damaging the concrete core sample.

[0024] In the utility model, the top cover is threadedly connected to the cylinder. Through the above arrangement, the purpose of inserting the top cover into the open position is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
