A concrete test block loading device

Abstract

This utility model discloses a concrete specimen filling device, which aims to solve the technical problem that the filling process in the existing technology mainly relies on traditional manual operation or simple filling equipment, requiring repeated movement of the hopper or shovel to fill each mold, resulting in low preparation efficiency. It includes a base plate and a hopper. Two support plates are symmetrically fixedly connected to the top surface of the base plate, and the support plates are fixedly connected to the hopper. Six tapered discharge pipes are fixedly connected to the bottom surface of the hopper, and each discharge pipe has an opening and closing control component on its side wall. A sliding plate is slidably connected to the top surface of the base plate, and a vibration platform is mounted on the top surface of the sliding plate. This utility model, by setting six tapered discharge pipes, can accurately connect to the mold opening. Combined with the opening and closing control components, concrete can fall directly into the mold, significantly reducing spillage. Compared with the traditional manual filling method, this greatly improves the preparation efficiency of concrete specimens.

Description

Technical Field

[0001] This utility model belongs to the field of concrete experimental technology, specifically relating to a concrete test block loading device. Background Technology

[0002] Concrete test blocks are a key carrier for testing the core properties of concrete, such as strength and durability, in building engineering. The quality of their production directly determines the accuracy of the test data, which in turn affects the safety of the engineering structure.

[0003] In the current process of concrete test block production, the filling process mainly relies on traditional manual operation or simple filling equipment. Each time a mold is filled, the hopper or shovel needs to be moved repeatedly, resulting in low preparation efficiency. Furthermore, it is impossible to accurately and fully vibrate the concrete after filling, which leads to large differences in the density of test blocks in the same batch. The subsequent strength test data fluctuates widely and is difficult to reflect the true performance of concrete.

[0004] Therefore, a concrete test block loading device was designed to overcome the above-mentioned technical defects. Utility Model Content

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a concrete test block loading device, including a base plate and a hopper. Two support plates are fixedly connected to the top surface of the base plate symmetrically on the left and right sides. The support plates are fixedly connected to the hopper.

[0022] This specific embodiment is a concrete test block loading device, the structural schematic diagram of which is shown below. Figures 1-4As shown, it includes a base plate 1 and a hopper 2. Two support plates 3 are fixedly connected to the top surface of the base plate 1 on the left and right sides respectively. The support plates 3 are fixedly connected to the hopper 2. Six discharge pipes 4 are fixedly connected to the bottom surface of the hopper 2. Three of the six discharge pipes 4 are set at the front and three at the back. The discharge pipes 4 are conical to facilitate the diversion of concrete and reduce residue. The side walls of the discharge pipes 4 are all equipped with opening and closing control components. A sliding plate 7 is slidably connected to the top surface of the base plate 1. A vibration platform is mounted on the top surface of the sliding plate 7.

[0023] like Figure 2 As shown, the opening and closing control assembly includes a through groove formed on the side wall of the feed pipe 4, a sealing plate 6 inserted into the through groove, and an electric push rod 5 installed on each side wall of the feed pipe 4. The telescopic end of the electric push rod 5 is connected to the sealing plate 6.

[0024] Specifically, when loading the test block mold, the sealing plate 6 at the corresponding position can be opened and closed according to the number and position of the test block mold to meet the needs of different number of test block molds; in addition, a mixing component can be directly set inside the hopper 2, which can achieve the purpose of concrete mixing and prevent concrete from solidifying.

[0025] like Figure 1 and Figure 4 As shown, two sliders 12 are fixedly connected to the bottom surface of the skateboard 7, and two grooves 13 are formed on the top surface of the base plate 1, with the sliders 12 slidably connected to the grooves 13. Two handles 11 are fixedly connected to the front side wall of the skateboard 7.

[0026] The slider 12 and the slide 13 can be replaced by a slide rail, and the handle 11 makes it easy to pull out the test block mold on the vibration platform, increasing the convenience of loading and unloading materials.

[0027] like Figure 3 As shown, the vibration platform includes a base 8 fixedly connected to the top surface of the slide plate 7. Multiple elastic elements 9 are mounted on the top surface of the base 8, and a common placement plate 10 is fixedly connected to the top of each elastic element 9. The placement plate 10 is used to support the concrete test block mold. A vibration motor is also installed on the bottom surface of the placement plate 10 to drive the placement plate 10 to generate vibration force. Since the vibration platform is a mature existing technology, it will not be described in detail in this solution.

[0028] like Figure 3 As shown, the top surface of the placement plate 10 has a concave structure. After the test block mold is placed, the concave structure of the placement plate 10 can, on the one hand, prevent concrete from spilling onto the base plate 1 during loading, and on the other hand, limit the test block mold during the compaction of concrete, preventing the test block mold from falling off the placement plate 10 during vibration.

[0029] Working principle: First, place the test block molds on the placement plate 10 in sequence. Then, pour the mixed concrete into the hopper 2 and start the electric push rod 5. The electric push rod 5 drives the sealing plate 6 to move outward and opens the discharge pipe 4, so that the concrete enters the test block mold through the discharge pipe 4. After filling is completed, the electric push rod 5 drives the sealing plate 6 to reset. Then, start the vibration motor on the vibration platform to synchronously vibrate the test block mold. After that, pull the handle 11 to move the slide plate 7 forward and remove the test block mold, and then carry out the next round of concrete filling.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
