A concrete slump test mechanism

Abstract

This utility model discloses a concrete slump testing mechanism, including a connecting frame. A slump cylinder is provided on the outer surface of the connecting frame. A lifting block is slidably connected to the inner sidewall of the connecting frame. A moving plate is slidably connected inside the lifting block. An elastic element is fixedly connected to the upper surface of the lifting block, and the outer surface of the elastic element is fixedly connected to the interior of the connecting frame. A scale is fixedly connected to the outer surface of the connecting frame. This device keeps the connecting frame level by adjusting the length of the telescopic legs and observing the spirit level bubble, preventing cement from slumping to one side. Concrete is poured into the slump cylinder, and a compaction mechanism compacts the concrete. The lifting block slides within the connecting frame, ensuring the moving plate is level with the connecting frame. By illuminating the scale with a laser pointer, the specific slump height can be clearly observed, effectively reducing errors caused by levelness and visual perception, and improving the accuracy of concrete slump testing.

Description

Technical Field

[0001] This utility model relates to the field of building material testing equipment technology, and in particular to a concrete slump testing mechanism. Background Technology

[0002] Concrete is usually made by mixing cement, aggregates, admixtures and water. It has many advantages such as high compressive strength, good durability and strong plasticity. Concrete slump mainly refers to the plasticity and pumpability of concrete. It is an important indicator for measuring the workability of concrete.

[0003] Currently, the main method involves placing a slump cone on a level surface, pouring in concrete, compacting it, moving the cone upwards, and measuring the height of the concrete using a measuring tape to determine the slump. However, when using the measuring tape, it is difficult to keep it level with the bottom surface, which can easily lead to visual errors and affect the accuracy of the concrete slump measurement. Therefore, we propose a concrete slump testing mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a concrete slump testing mechanism to solve the problems mentioned in the background art.

[0011] In a further embodiment, a slide cylinder is fixedly connected to the outer surface of the connecting frame, and a funnel is slidably connected to the inner sidewall of the slide cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device keeps the connecting frame level by adjusting the length of the telescopic legs and observing the level bubble, preventing cement from collapsing to one side. Concrete is poured into the slump cylinder and compacted by the tamping mechanism. The lifting block slides within the connecting frame, ensuring that the moving plate and the connecting frame are on the same horizontal plane. By shining a laser pointer onto the scale, the specific height of the slump can be clearly observed, effectively reducing errors caused by level and visual perception, and improving the accuracy of concrete slump measurement.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model discloses a concrete slump testing mechanism, comprising a connecting frame 1, a slump cylinder 2 on the outer surface of the connecting frame 1, a lifting block 3 slidably connected to the inner side wall of the connecting frame 1, a moving plate 4 slidably connected to the inside of the lifting block 3, an elastic element 5 fixedly connected to the upper surface of the lifting block 3, the outer surface of the elastic element 5 fixedly connected to the inside of the connecting frame 1, a scale 6 fixedly connected to the outer surface of the connecting frame 1, a laser pointer 7 fixedly connected to the outer surface of the moving plate 4, a tamping mechanism 8 fixedly connected to the outer surface of the moving plate 4, multiple telescopic legs 9 fixedly connected to the bottom surface of the connecting frame 1, and a level bubble 10 fixedly connected to the upper surface of the connecting frame 1. By sliding the lifting block 3 within the connecting frame 1, the moving plate 4 can be kept on the same plane as the connecting frame 1. By adjusting the length of the telescopic legs 9 in conjunction with the level bubble 10, the connecting frame 1 can be kept horizontal. By setting the elastic element 5, the lifting block 3 is positioned at the top, avoiding interference with the use of the slump cylinder 2. By illuminating the scale 6 with the laser pointer 7, the change in height can be accurately displayed.

[0023] The compaction mechanism 8 includes a connecting plate 801, a slewing bearing 802 fixedly connected to the upper surface of the connecting plate 801, a motor 803 fixedly connected to the outer surface of the connecting frame 1, a gear 804 fixedly connected to the output end of the motor 803, the gear 804 meshing with the slewing bearing 802, an electric push rod 805 fixedly connected to the upper surface of the slewing bearing 802, and a compaction rod 806 fixedly connected to the output end of the electric push rod 805. The motor 803 drives the gear 804 and the slewing bearing 802 to rotate. After rotating a certain angle, the motor 803 is stopped, and the electric push rod 805 is turned on to drive the compaction rod 806 to move up and down. The motor 803 is turned on again, and the above operation is repeated multiple times to complete the compaction of concrete.
