Description

Technical Field

[0001] The utility model relates to pressure testing equipment for concrete test blocks, belonging to the technical field of concrete testing equipment. Background Art

[0002] Concrete has the characteristics of rich raw materials, good mechanical properties, plasticity and durability, and wide adaptability. It is one of the most important building materials in contemporary times and the most widely used artificial building material in the world. At the same time, as a structural material, concrete must have sufficient strength to resist the destructive effects of various loads. Since the compressive strength is much greater than other strengths, the most important mechanical indicator of concrete is the compressive strength. When concrete is used, it is necessary to use concrete testing equipment to test its compressive strength to ensure the reliability of concrete use. However, the existing concrete testing equipment still has certain shortcomings and deficiencies during use. Since the placement table of the existing concrete testing equipment is too high, the staff needs to lift the concrete test block to the placement table so that the concrete testing equipment can perform compressive strength testing. The weight of the concrete test block is heavy, and multiple workers are required to lift it, which makes the compressive strength testing of the concrete test block time-consuming and laborious, reduces the work efficiency of the test, and the concrete test block is not lifted firmly and is easy to fall and hurt the foot. At the same time, when the concrete test block is impacted, a large impact force will be generated on the placement table, making the concrete testing equipment easy to shake, and also causing the placement table to be compressed and deformed.

[0026] When the placing table 102 is in use, the mounting block 304 at the bottom of the placing table 102 is fixedly connected to the top of the multi-stage telescopic rod b303, so that the mobile base 3, the support platform 301, the lifting cylinder 302, the multi-stage telescopic rod b303 and the placing table 102 form a whole, and the placing table 102 can be driven to move by the moving wheels at the bottom of the mobile base 3. When the placing table 102 is installed on the mobile base 3, it is in a low position. At this time, the worker can lift the concrete test block onto the placing table 102. Since the placing table 102 is arranged in a concave shape, it is convenient to limit the concrete test block on the placing table 102, and push the placing table 102, so that the multi-stage telescopic rod b303 and The mobile base 3 is acted upon by the thrust and moves the placement table 102 to the inside of the box a101.

[0030] When the mobile base 3 is pushed into the box a101, the two sides of the outer end of the mobile base 3 just enter the limit groove 501 inside the limit block 5, so that the mobile base 3 is engaged and connected to the limit block 5. At this time, the brake pedal on the outside of the moving wheel is stepped on to lock the moving wheel, and the mobile base 3 is clamped in cooperation with the limit block 5, so that the mobile base 3 is firmly placed inside the box a101 to prevent the mobile base 3 from shifting.

[0031] Among them, Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a fixing screw hole 502 is provided between the limit block 5 and the inner wall of the box a101, a positioning screw 503 is threadedly connected to the inside of the fixing screw hole 502, a hand crank 504 is welded to the outer end of the positioning screw 503, a positioning screw hole 6 is provided on one side of the outer end of the movable base 3, and the positioning screw 503 passes through the fixing screw hole 502 and extends to the inside of the positioning screw hole 6.

[0032] When the movable base 3 is engaged and connected to the limit block 5, the positioning screw hole 6 at the outer end of the movable base 3 is just connected and tightly fitted with the fixed screw hole 502. At this time, grasp the hand crank 504 to screw the positioning screw 503 from the fixed screw hole 502 into the inside of the positioning screw hole 6, and continue to shake the hand crank 504 until the positioning screw 503 is tightened inside the fixed screw hole 502 and the positioning screw hole 6, thereby increasing the firmness between the movable base 3 and the limit block 5, avoiding the situation where the movable base 3 moves, and ensuring that the placement table 102 has good stability to support the placement of the concrete test block.

[0033] Embodiment 2

[0034] Based on the first embodiment, Figure 2 As shown, the buffer assembly includes: a buffer rod 7, an electromagnet a701, a damper 702, an electromagnet b703, a movable pressure block 704 and a buffer spring 705. Buffer rods 7 are respectively provided on both sides of the bottom of the placement table 102, an electromagnet a701 is provided between the buffer rod 7 and the placement table 102, a damper 702 is provided at the bottom of the buffer rod 7, and the buffer rod 7 runs through the inside of the damper 702, an electromagnet b703 is provided between the damper 702 and the support table 301, a movable pressure block 704 is installed at the bottom end of the buffer rod 7, and a buffer spring 705 is provided between the movable pressure block 704 and the bottom end of the damper 702.

[0035] After the placement table 102 and the concrete test block are transported to the inside of the protection box 2, the electromagnet a701 and the electromagnet b703 are electrically connected to the battery and the controller through wires, and the electromagnet a701 and the electromagnet b703 are powered by the battery. The top of the buffer rod 7 is placed in the electromagnet a701, and the bottom of the damper 702 is placed in the electromagnet b703. Since the electromagnet a701 and the electromagnet b703 are arranged in a concave structure, they can fit and clamp with the top of the buffer rod 7 and the bottom of the damper 702. At this time, through the controller Start the electromagnet a701 and the electromagnet b703 to generate a magnetic field, and magnetically fix the buffer rod 7 and the damper 702 on the placement table 102 and the support table 301 respectively. When the concrete test block is impact tested, an impact force will be generated on the placement table 102. The buffer rod 7 at the bottom of the placement table 102 compresses the buffer spring 705 into the damper 702, thereby reducing a part of the impact force generated on the placement table 102, so that the concrete testing equipment is placed stably, and the placement table 102 can be prevented from being deformed after being subjected to the impact pressure, while also protecting the multi-stage telescopic rod b303.

[0036] Among them, Figure 2 As shown, a box b8 is installed at the bottom of the pressure testing machine 4, a storage cavity 801 is opened inside the box b8, and a box door 802 is rotatably connected to the outside of the box b8 through a hinge.

[0037] After completing the compression test of the concrete test block, the controller turns off the operation of electromagnet a701 and electromagnet b703, so that electromagnet a701 and electromagnet b703 lose their magnetic field, making it easier to remove the buffer rod 7 and the damper 702, and then put the buffer rod 7 and the damper 702 into the storage chamber 801 for easy taking and use. The controller then controls the lifting cylinder 302 to drive the multi-stage telescopic rod b303 to move downward, and the multi-stage telescopic rod b303 drives the placement table 102 and the concrete test block to move out of the protection box 2, so as to facilitate cleaning of the debris on the placement table 102. The hand crank 504 is turned to loosen and remove the fixing screw hole 502 and the positioning screw hole 6 of the positioning screw 503, and the brake pedal on the outside of the moving wheel is lifted, so that the moving base 3 can be moved out of the box a101, so as to facilitate cleaning of the debris inside the box a101.
