Description

Technical Field

[0001] This utility model relates to the field of experimental platform technology, and in particular to an experimental platform for green high-performance concrete. Background Technology

[0002] The concrete testing platform is also known as a concrete vibration table. The concrete vibration table is mainly composed of a base frame, vibrator and springs. The table and base frame are welded from steel plates and shaped steel. The vibration table is composed of an electric motor and a pair of identical eccentric wheels, which are installed at the center of the table (reverse side) through a pair of hanger couplings. It plays a role in stabilizing and vertically controlling the compaction process. It is suitable for the preparation of test specimens and the compaction of precast components such as slabs, columns and beams in laboratories and on-site construction sites.

[0003] An existing experimental platform for green high-performance concrete (announcement number: CN217725618U) has the following drawbacks: the platform body drives the concrete test block to vibrate, and too much concrete will fall onto the top of the platform body. Since there is no discharge port inside the experimental frame, the fallen concrete will splatter onto the inner wall of the experimental frame, which is not conducive to opening the experimental frame. In addition, the placement plate is fixedly connected to the top of the platform body, making it impossible to conduct experimental testing on multiple poured concrete test blocks.

[0023] Reference Figures 1-4An experimental platform for green high-performance concrete includes a frame 1, a vibration table 2, and a collection box 5. The vibration table 2 is located on top of the frame 1. Several slots 201 are provided on all four sides of the vibration table 2. A cross-shaped insert 3 is provided inside the vibration table 2. The multiple ends of the cross-shaped insert 3 are inserted into the slots 201. The cross-shaped insert 3 is attached to the inner wall of the vibration table 2. A discharge port 202 is provided at the bottom of one side of several slots 201. The discharge port 202 is provided through one side of the vibration table 2. A feeding rack 4 is provided on one side of the discharge port 202. The feeding rack 4 is welded to the outside of the vibration table 2. A positioning groove 101 is provided on one side of the top of the frame 1. The collection box 5 is placed inside the positioning groove 101. The collection box 5 is located at the bottom of the feeding rack 4. A vibrator 203 is provided on one side of the collection box 5. The vibrator 203 is fixedly connected to the bottom of the vibration table 2. Springs 204 are fixedly connected to the four corners of the bottom of the vibration table 2.

[0024] During use, the staff adjusts the cross bracket 3 according to the size and quantity of the test block molds, inserts the cross bracket 3 into the slot 201 on the outside of the vibration table 2 to fix the cross bracket 3 in place, and then places the test block molds between the cross brackets 3 to limit the test block molds. After the concrete is poured into the test block molds, the staff starts the vibrator 203, which vibrates the vibration table 2, causing the test block molds on the top of the vibration table 2 to vibrate and compact the concrete inside the test block molds. Excess concrete falls into the vibration table 2. The bottom of the cross bracket 3 is suspended to facilitate the flow of excess concrete. A discharge port 202 is opened on one side of the vibration table 2, which allows the fallen concrete to flow through the discharge port 202 into the unloading rack 4, and then into the collection box 5 for collection, preventing the excess concrete accumulated inside the vibration table from spreading and increasing the cleaning workload for the staff.

[0025] In this embodiment, the bottom of the vibration table 2 is provided with a base frame 205, which is fixedly connected to the top of the frame 1 by bolts. The bottom end of the spring 204 is fixedly connected to the top circular groove of the base frame 205. Shock absorbers 102 are fixedly connected to the four corners of the top of the inner wall of the base frame 205. The bottom of the shock absorbers 102 is fixedly connected to the top of the frame 1. Several casters 104 are fixedly connected to the bottom of the frame 1. A side sliding groove 6 is opened on one side of the outer side of the frame 1.

[0026] During use, the vibration generated by the vibrator 203 is transmitted to the base frame 205 through the spring 204. At the same time, the shock absorber 102 reduces the vibration on the base frame 205 to prevent the frame 1 from deforming or bending due to long-term vibration.

[0027] In this embodiment, the side slide groove 6 includes a lead screw 601, a pulley 602, and a drive motor 603. Both ends of the lead screw 601 are rotatably connected to the inner wall of the side slide groove 6 and are connected through to the outside of the frame 1. One end of the lead screw 601 is fixedly connected to one side of the pulley 602. The drive motor 603 is fixedly connected to the inside of the frame 1. The other side of the pulley 602 near the lead screw 601 is fixedly connected to the transmission shaft of the drive motor 603. The outer side of the frame 1 is fixedly connected to a housing 7.

[0028] During use, since the pulley 602 is close to the ground, the housing 7 needs to protect the pulley 602 to prevent it from being exposed to the air for a long time, causing sand and gravel on the ground to adhere to the belt groove and cause some wear to the belt. The bottom of the frame 1 is equipped with casters 104 to facilitate the transfer of the experimental platform indoors and outdoors by the staff.

[0029] In this embodiment, the pulley 602 is located inside the housing 7, and a limiting groove 103 is provided on the top of the frame 1. A movable frame 8 is provided on the side of the frame 1 near the side slide groove 6. The movable frame 8 includes a side slide block 801, a limiting block 802 and a crossbar 804. The side slide block 801 is located inside the side slide frame and is threadedly connected to the lead screw 601. The limiting block 802 is located on the top of the side slide block 801. One end of both the side slide block 801 and the limiting block 802 is fixedly connected to the movable frame 8.

[0030] When in use, start the drive motor 603. The drive motor 603 drives the pulley 602 to rotate. At the same time, the pulley 602 rotates and drives the lead screw 601 to rotate. The lead screw 601 drives the sliding block 801 to move in the side sliding groove on one side of the frame 1. At the same time, the sliding block 801 drives the moving frame 8, the crossbar 804 and the sliding frame 9 to move laterally. The sliding frame 9 follows the moving frame 8 to move in position, which facilitates the horizontal pouring of concrete.

[0031] In this embodiment, the bottom end of the limiting block 802 is slidably connected to the inside of the limiting groove 103, the top end of the movable frame 8 is provided with a rotating groove 803, the crossbar 804 is located inside the rotating groove 803, a rotating valve 805 is provided on one side of the movable frame 8, the crossbar 804 is rotatably connected to the inside of the rotating groove 803 through the rotating valve 805, a sliding frame 9 is provided on one side of the movable frame 8, the sliding frame 9 is slidably connected to the crossbar 804, and the sliding frame 9 includes an infusion frame 901, an inner ring groove 902 and an installation tube 903.

[0032] In use, the limiting block 802 increases the connection between the movable frame 8 and the frame 1, while reducing the moving resistance of the sliding block 801. The operator rotates the rotary valve 805, which drives the crossbar 804 to rotate in the rotary groove 803, thereby increasing the distance between the sliding frame 9 and the vibration table 2, making it easier to pour concrete for test block molds of different heights.

[0033] In this embodiment, a rotating ring 904 is fixedly connected to the bottom of the mounting tube 903. The rotating ring 904 is rotatably connected inside the inner ring groove 902. The inner ring groove 902 is opened inside the top of the infusion frame 901. The infusion frame 901 is integrally connected to the side of the sliding frame 9. The sliding frame 9 is located at the top of the vibration table 2. The top of the vibration table 2 is provided with an adjusting valve 10. The rod of the adjusting valve 10 is threadedly connected to the sliding frame 9 and abuts against one side of the crossbar 804.

[0034] In use, the operator connects the discharge pipe of the mixing tank to the installation pipe 903, rotates the installation pipe 903, and the installation pipe 903 rotates in the inner ring groove 902 at the top of the pouring frame 901 by the rotating ring 904, so that the discharge pipe and the installation pipe 903 are threadedly connected. The operator rotates the regulating valve 10 to release the fixed connection between the sliding frame 9 and the crossbar 804. The operator pushes the sliding frame 9, and the sliding frame 9 drives the discharge pipe to move on the crossbar 804, which facilitates the vertical pouring of concrete.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The operator connects the discharge pipe of the mixing tank to the installation pipe 903, rotates the installation pipe 903 to make the discharge pipe and installation pipe 903 threadedly connected, starts the drive motor 603, the drive motor 603 drives the pulley 603 to rotate, and the pulley 602 drives the screw 601 to rotate simultaneously. The screw 601 drives the moving frame 8 to move on one side of the frame 1, and the sliding frame 9 follows the moving frame 8 to move its position, facilitating the horizontal pouring of concrete. The operator rotates the regulating valve 10 to disengage the sliding frame 9 from the crossbar 804, and pushes the sliding frame 9, which drives the discharge pipe to reciprocate on the crossbar 804, facilitating the vertical pouring of concrete. This arrangement is beneficial for pouring concrete from multiple test block molds and allows for the simultaneous pouring of multiple concrete test blocks. In the experimental testing, the staff adjusted the cross brackets 3 according to the size and quantity of the test block molds. The cross brackets 3 were then inserted into the slots 201 on the outside of the vibration table 2 to fix them in place. The test block molds were then placed between the cross brackets 3 to limit their movement. After the concrete was poured into the test block molds, the staff started the vibrator 203, which vibrated the vibration table 2, causing the test block molds on top of the vibration table 2 to vibrate as well. This compacted the concrete inside the test block molds, and the excess concrete fell into the vibration table 2. The bottom of the cross brackets 3 was suspended to facilitate the flow of excess concrete. A discharge port 202 was provided on one side of the vibration table 2, allowing the fallen concrete to flow through the discharge port 202 into the unloading rack 4. From there, the unloading rack 4 entered the collection box 5 for collection, preventing the excess concrete accumulated inside the vibration table from spreading and increasing the cleaning workload for the staff.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
