Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a movable concrete compression test piece manufacturing device. Background Art

[0002] During the construction of bridges and roads, samples of each batch of concrete need to be taken to produce compressive strength test blocks, and the compressive strength test blocks are tested to determine whether the concrete strength of the batch is qualified. The existing concrete mixing and pouring on-site production of compressive strength test blocks usually uses manual molding and manual vibration to compact. For large projects, there are too many batches of concrete mixed per day and many pouring points (that is, concrete will be made on-site in different places). When manual molding and vibration are used, 4-6 people are usually required to operate simultaneously, which is labor-intensive, inefficient, and costly. Summary of the invention

[0003] The present invention aims to provide a movable concrete compression test piece manufacturing device capable of automatic vibration, which is used to replace the manually manufactured compression strength test blocks, so as to solve the problem of time-consuming and labor-intensive manual manufacturing of compression strength test blocks in large projects.

When in use, the conductive concrete production site of the present invention is made through the travel of the locomotive, and then the feed hopper is docked with the discharge port of the concrete mixing mechanism to receive the output concrete, and the concrete enters the concrete compression test piece forming mold. In this process, the concrete compression test piece forming mold is vibrated by the vibrator to make the concrete in the concrete compression test piece forming mold dense.

[0005] Preferably, the concrete compression test piece forming mold comprises a mold shell, and the mold shell is provided with at least three rows and three columns of through holes extending in the up-down direction for forming the concrete compression test piece.

After the concrete compression test piece hardens, it pushes the cavity bottom plate upward so that the concrete compression test piece, together with the cavity bottom plate, the cavity front wall plate, the cavity left wall plate, the cavity rear wall plate and the cavity right wall plate, are released from the through hole. The cavity bottom plate, the cavity front wall plate, the cavity left wall plate, the cavity rear wall plate and the cavity right wall plate are released from the concrete compression test piece to take out the concrete compression test piece. The concrete compression test piece can be easily demoulded without disassembling the concrete compression test piece forming mold. If the compression strength test piece is demoulded by disassembling the concrete compression test piece forming mold, it is inconvenient to demould the middle compression strength test piece when the layout is multi-row and multi-column, and the compression strength test piece is easily damaged when it is squeezed out.

A connecting pin 8 is provided at the lower end of the concrete compression test piece forming mold, and a connecting hole 9 is provided on the upper surface of the support plate. The connecting pin is inserted into the connecting hole in a pluggable manner. The connecting pin and the connecting hole are only matched so that when the support plate descends, the concrete compression test piece forming mold can be pulled down together. The vibrator also includes a left reversing rod 10 whose lower end is connected to the locomotive and a front reversing rod 11 whose lower end is connected to the locomotive; a left elongated guide hole 12 extending in the front-to-back direction is provided on the left side of the support plate, the left elongated guide hole penetrates the support plate in the up-down direction, the left reversing rod is inserted into the left elongated guide hole, and the left reversing rod is inclined with the upper end facing the left; a front elongated guide hole 13 extending in the left-to-right direction is provided on the front side of the support plate, the front elongated guide hole penetrates the support plate in the up-down direction, the front reversing rod is inserted into the front elongated guide hole, and the front reversing rod is inclined with the upper end facing the front.

[0022] The rigid vertical feed pipe 15 is connected to the concrete compression test piece forming mold through a flexible section 14. The flexible section is sleeved on the concrete compression test piece forming mold and is detachably connected together. The rigid vertical feed pipe is provided with an elastic lining layer 16, and an annular air cavity 17 extending along the circumference of the rigid vertical feed pipe is formed between the elastic lining layer and the rigid vertical feed pipe. The annular air cavity is filled with gas so that the elastic lining layer is in a bulging state. The feed hopper is provided with a rigid vertical discharge pipe 18 penetrating the rigid vertical feed pipe. The rigid vertical discharge pipe is penetrating the elastic lining layer, and the elastic lining layer is inflated at the part below the rigid vertical discharge pipe to protrude into the interior of the rigid vertical discharge pipe; when the concrete compression test piece forming mold is lifted or lowered, the rigid vertical feed pipe is driven to lift or lower, and when the concrete compression test piece forming mold is moved in the horizontal direction, the deformation of the flexible section is used to prevent the rigid vertical feed pipe from moving horizontally.

[0023] The concrete compression test piece forming mold comprises a mold shell, and the mold shell is provided with three rows and four columns, a total of 12 through holes extending in the up-down direction for forming the concrete compression test piece. The through holes are movably penetrated with a cavity bottom plate 21 (the cavity bottom plate is directly placed on the support plate), a cavity front wall plate 22, a cavity left wall plate 23, a cavity rear wall plate 24 and a cavity right wall plate 25, and the lower ends of the cavity front wall plate, the cavity left wall plate, the cavity rear wall plate and the cavity right wall plate are all supported on the upper surface of the cavity bottom plate, and the cavity front wall plate, the cavity left wall plate, the cavity rear wall plate and the cavity right wall plate are only abutted together to achieve detachable connection, and the cavity bottom plate, the cavity front wall plate, the cavity left wall plate, the cavity rear wall plate and the cavity right wall plate surround the cavity 20 for forming the concrete compression test piece 19.

[0024] The process of making the compressive strength test block of the present invention is as follows: the feed hopper is connected to the discharge port of the concrete mixer, and the concrete outputted by the concrete mixer is input into the cavity through the feed hopper. After the concrete in the cavity is solidified, the flexible section is separated from the concrete compressive test piece forming mold, the concrete compressive test piece forming mold together with the compressive strength test block is transferred to other places, and then the concrete test block is taken out.

[0025] In the process of inputting concrete into the cavity, the vibrator vibrates the concrete compression test piece forming mold to make the concrete entering the cavity dense. The specific vibration process of the vibrator is as follows: the knocking rod drives the cylinder to drive the knocking rod to move upward to knock the pallet to make the pallet rise, the knocking rod drives the cylinder to drive the knocking rod to move downward and lose the function of lifting the pallet, and the pallet moves downward and resets under the action of the tension spring. The above process makes the concrete compression test piece forming mold vibrate in the up and down directions to make the concrete injected into the concrete compression test piece forming mold dense, and the speed of the knocking rod descending is greater than the speed of the concrete compression test piece forming mold descending. In the process of the knocking rod and the tension spring driving the pallet to rise and fall, the pallet reciprocates in the left and right directions under the action of the left reversing rod and the left long strip guide hole, so that the concrete compression test piece forming mold vibrates in the left and right directions, and the pallet reciprocates in the front and back directions under the action of the front reversing rod and the front long strip guide hole, so that the concrete compression test piece forming mold vibrates in the front and back directions.

[0026] The specific process of taking out the concrete specimen is as follows: after the concrete compression specimen hardens, the cavity bottom plate is pushed upward so that the concrete compression specimen, together with the cavity bottom plate, cavity front wall plate, cavity left wall plate, cavity rear wall plate and cavity right wall plate, are ejected from the through hole; the cavity bottom plate, cavity front wall plate, cavity left wall plate, cavity rear wall plate and cavity right wall plate are separated from the concrete compression specimen to take out the concrete compression specimen. The upper end of the concrete compression test piece is lower than the upper ends of the front wall plate of the cavity, the upper ends of the left wall plate of the cavity, the upper ends of the rear wall plate of the cavity and the upper ends of the right wall plate of the cavity; the method for separating the cavity bottom plate, the front wall plate of the cavity, the left wall plate of the cavity, the rear wall plate of the cavity and the right wall plate of the cavity from the concrete compression test piece is as follows: knocking the rear surface of the upper end of the front wall plate of the cavity forward to separate the front wall plate of the cavity from the concrete compression test piece, knocking the right surface of the upper end of the left wall plate of the cavity forward to separate the left wall plate of the cavity from the concrete compression test piece, knocking the front surface of the upper end of the rear wall plate of the cavity backward to separate the rear wall plate of the cavity from the concrete compression test piece, knocking the left surface of the upper end of the right wall plate of the cavity forward to separate the right wall plate of the cavity from the concrete compression test piece, and knocking the upper surface of the bottom plate of the cavity plate downward beyond the position of the concrete compression test piece to separate the bottom plate of the cavity from the concrete compression test piece.
