Description

Technical Field

[0001] The utility model relates to a concrete detection device, belonging to the field of concrete detection. Background Art

[0002] In the construction of building projects, concrete is the key to the building. The quality of concrete is related to the quality of the project. The measurement of concrete slump before concrete pouring is a key method for concrete quality detection. First, the concrete is filled into a conical cylinder, and the conical cylinder is placed on a flat plate. Then the conical cylinder is pulled upward to allow the concrete to collapse freely, and then the collapsed concrete is measured. This method requires the flat plate and the conical cylinder to cooperate with each other. The flat plate is convenient for the collapse and diffusion of concrete. At present, the size of the flat plate is generally fixed and cannot be adjusted according to needs. Larger flat plates are not convenient to carry, and smaller flat plates will cause concrete to spread to the outside of the flat plate. Therefore, it is necessary to design a concrete detection device that can adjust the area of ​​the concrete collapse and diffusion platform. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a concrete detection device to solve the problems raised in the above-mentioned background technology. The utility model makes the area of ​​the concrete collapse diffusion platform adjustable and convenient to carry.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a concrete detection device, including a conical cylinder, the upper end and the lower end of the conical cylinder are both open, and a plurality of mutually plugged bases are arranged on the lower side of the conical cylinder, and the base is a square structure, and slots are opened in the middle of the four sides of the base, and plug plates are inserted in the slots, the length of the plug plates is twice the depth of the slots, and the ends of the plug plates are restricted in the slots by pins, and horizontal adjustment members are installed at the four corners of the upper surface of the base.

[0005] Furthermore, the horizontal adjustment member includes a cylinder, and vertical holes are arranged vertically at the four corners of the upper surface of the base. The cylinder is installed in the vertical hole, and a limit ring is connected and fixed in the lower position of the cylinder. A circular ring is installed in the upper position of the cylinder. The inner surface of the circular ring is processed with an internal thread, and the inner thread of the circular ring is connected with an extrusion screw. A pillar is provided in the cylinder, and the lower end of the pillar is inserted in the limit ring, and the upper end of the pillar is inserted in the circular ring. The outer surface of the upper end of the pillar is sleeved with a slip ring connected and fixed to the pillar, and the slip ring is slidably installed in the cylinder. A spring is provided between the slip ring and the limit ring, and the spring is sleeved on the pillar.

[0006] Furthermore, the slip ring and the pillar are an integrally formed structure, the outer diameter of the pillar is the same as the inner diameter of the circular ring, and the inner diameter of the limiting ring is the same as the outer diameter of the pillar.

[0007] Furthermore, the upper surface of the plug plate is provided with two symmetrically arranged pin holes, the top of the slot is provided with a through hole aligned with the pin hole, and a pin rod is inserted in the channel formed by the through hole and the pin hole.

[0008] Furthermore, two handles are symmetrically provided on the outer surface of the upper end of the conical tube, both ends of the handles are connected and fixed to the conical tube, and the handles are U-shaped structures.

[0009] Furthermore, two symmetrically arranged support plates are connected and fixed to the outer surface of the lower end of the conical cylinder, one end of the support plate away from the conical cylinder is processed with a rounded corner, and the bottom of the support plate is flush with the bottom of the conical cylinder.

[0010] Beneficial effects of the utility model:

[0011] 1. Select a suitable number of bases as needed, and insert the plug plate in the space formed by two aligned slots. At this time, the pin hole on the plug plate is aligned with the through hole in the slot, so that the pin rod is inserted in the channel formed by the through hole and the pin hole, so as to limit the relative position of the plug plate and the base, that is, the relative position of two adjacent bases is restricted, and multiple bases are connected to each other, so that multiple bases form a platform for concrete collapse diffusion, without the need to use large-sized plates, which is convenient for split carrying. At the same time, the area of ​​the concrete collapse diffusion platform can be changed by increasing or decreasing the number of bases as needed.

[0012] 2. When the ground where the platform for concrete collapse and diffusion formed by multiple bases is located is uneven, an extrusion screw is screwed into the circular ring at the outermost corner of the four outermost bases. At this time, the extrusion screw squeezes the pillar, and the pillar drives the slip ring to move downward in the cylinder. At this time, the slip ring and the limit ring work together to squeeze the spring, causing the spring to produce elastic deformation. At the same time, the lower end of the pillar passes through the limit ring and extends to the lower side of the base and contacts the ground under the base. At this time, the four pillars realize horizontal support for the concrete collapse and diffusion platform formed by the multiple bases, avoiding the base being in an inclined state to affect the concrete collapse and diffusion. At the same time, it is convenient to place the base on an uneven ground without leveling the ground. When the extrusion screw is separated from the circular ring, under the action of the spring rebound force, the lower end of the pillar is retracted into the limit ring and the upper end of the pillar is inserted into the circular ring. At this time, the pillar realizes real-time blocking of the thread pattern in the circular ring to prevent small debris from entering the thread pattern of the circular ring. At the same time, the pillar retracts into the limit ring without affecting the stacking of multiple bases. BRIEF DESCRIPTION OF THE DRAWINGS
