Embodiment 1

[0029] refer to Figure 1~4 , in an embodiment of the present invention, a multi-point strength detection device for a cylindrical concrete sample core for construction engineering, comprising a fixed base 1, a limit groove 2 is provided in the middle of the upper end of the fixed base 1, and a limit block 3 is slidably arranged inside the limit groove 2, The limit block 3 can move along the inside of the limit groove 2, thereby ensuring the clamping effect on concrete sample cores of different lengths, and the inside of the limit block 3 is provided with an internal thread that cooperates with the rotating shaft 12 hole, so that the rotary motion of the rotating shaft 12 is converted into the left and right linear motion of the limit block 3, the rotating shaft 12 is installed between the middle parts of the limit block 3, and the right end of the rotating shaft 12 passes through the fixed base 1 and is connected with a rotating handle 13. It is used to drive the rotating sha...

Embodiment 2

[0031] In another embodiment of the present invention, the difference between this embodiment and the above-mentioned embodiment is that several clamping springs 30 are installed at one end of the inner side of the rotating frame 10, and a clamping ring 31 is installed at the other end of the clamping springs 30. Setting the clamping spring 30 and the clamping ring 31 can fix concrete sample cores with different diameters.

[0032]In the present invention, when working, the concrete sample core to be detected is placed between the clamping frames 10, and then the rotating handle 13 is rotated, so that the rotating shaft 12 is rotated, so that the limiting block 3 moves along the direction of the support column 4, and then Realize the clamping and fixing of both ends of the concrete sample core. When the circumferential surface of the sample core needs to be detected, the driving motor 20 is started, and the driving motor 20 drives the driving inclined column 23 to rotate, and t...

Abstract

The invention relates to the technical field of construction equipment, and discloses a cylindrical concrete sample core multipoint strength detection device for constructional engineering. The devicecomprises a fixed base, wherein a limiting groove is formed in the middle part of the upper end of the fixed base, limiting blocks are slidably arranged in the limiting groove, a rotating shaft is mounted between the middle parts of the limiting blocks, a left-hand thread is formed in the middle part of the left side of the rotating shaft, a right-hand thread is formed in the middle part of the right side of the rotating shaft, moving columns are installed at the upper end of the limiting blocks, rotary shafts are installed in the middles of the moving columns through bearings, rotating frames are installed at one ends of the inner sides of the rotary shafts, a supporting column is installed in the middle of the upper end of the fixed base, a supporting ring is installed at the top end ofthe supporting column, hydraulic cylinders are installed on both sides of the upper end of the fixed base, and hydraulic shafts are installed at the top ends of the hydraulic cylinders. According tothe device, up-and-down movement of an extrusion block is achieved, the extrusion effect on a concrete sample core is ensured, meanwhile, through mutual cooperation of the arranged limiting blocks andclamping frames, the clamping and fixing effect on the cylindrical concrete sample core is achieved, and angle rotation can also be achieved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a multi-point strength detection device for cylindrical concrete sample cores used in construction engineering. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics...
