Description

Technical Field

[0001] This utility model relates to the technical field of concrete testing devices, specifically a concrete testing device for water conservancy construction projects. Background Technology

[0002] Concrete is an essential material in hydraulic engineering construction, and its strength is a crucial indicator of concrete performance. Therefore, concrete strength testing plays a vital role in hydraulic engineering projects. Generally, the concrete is placed on a detector, and its strength is measured by gradually compressing it using the detector's extrusion device.

[0003] In actual use, if the concrete to be tested is not placed in the exact center of the testing device during the actual use of the current concrete testing equipment in water conservancy construction projects, the force-bearing area may be reduced, resulting in inaccurate test data. At the same time, if the concrete is not fixed before testing, it may move during the force test, which may cause the concrete to deviate from the testing device during the test, resulting in test failure. Utility Model Content

[0004] This utility model provides a concrete testing device for water conservancy construction projects. It can clamp the concrete to be tested from multiple directions by setting up several clamping plates, making the concrete more stable during testing. At the same time, while the clamping plates are clamping and moving, they can push concrete blocks that are not in the center of the test to the center, so that the test data is more accurate.

[0005] To achieve the above objectives, a concrete testing device for water conservancy construction projects is provided, comprising a mounting shell, a fixed plate fixedly connected to the inner wall of the mounting shell, a plurality of sliding grooves formed at equal angles on the surface of the fixed plate, a rotating disk rotatably connected to the bottom surface of the fixed disk, an adjusting groove formed at equal angles on the surface of the rotating disk, a plurality of adjusting grooves formed at equal angles on the surface of the adjusting groove, a movable column slidably connected to the inner wall of the adjusting groove, a sliding block fixedly connected to the upper end of the movable column, the sliding block slidably connected inside the sliding groove, a clamping plate fixedly connected to the upper end of the sliding groove, and a hydraulic cylinder fixedly mounted on the top surface of the mounting shell, the movable end of the hydraulic cylinder passing through the mounting shell and fixedly connected to a pressure sensor. By setting an adjustment groove, the rotating disk rotates and drives the moving column and sliding block to move. While the sliding block is moving, the contact with the sliding block limits the movement of the sliding block, allowing the sliding block to slide along the sliding groove. Then, the sliding block drives the clamping plate to move synchronously towards or away from each other, moving the concrete to the detection center of the pressure sensor and clamping it stably, so that the pressure sensor can perform extrusion detection.

[0006] According to the concrete testing device for water conservancy construction engineering, a plurality of sliding rods are slidably connected inside the clamping plate. A clamping block is fixedly connected to one adjacent end of each sliding rod, and a limiting plate is fixedly connected to the end of each sliding rod away from the clamping block. A spring is sleeved on the outer surface of each sliding rod, and both ends of the spring are fixedly connected to the clamping block and the clamping plate, respectively. By setting the spring, the clamping block can further tighten the concrete, thus enhancing the clamping effect. The limiting plate, in cooperation with the sliding rod, limits the sliding rod, preventing it from detaching.

[0007] According to the concrete testing device for water conservancy construction projects, the clamping block is made of rubber and is trapezoidal in shape, and a testing display is fixedly installed on the top surface of the mounting shell. By setting the clamping block to a trapezoidal shape, the contact area of ​​the clamping block when clamping concrete is reduced, the pressure is increased, and the clamping effect is more stable. The use of rubber material for the clamping block buffers the initial impact with the concrete, preventing damage to the concrete from affecting the testing results.

[0008] According to the concrete testing device for hydraulic construction projects, the outer surface of the mounting shell has a placement opening, and two hinged closing doors are provided on both sides of the placement opening. When closed, the closing doors fit snugly against the outer surface of the mounting shell, and a pull handle is fixedly installed on the outer surface of the closing doors. By setting the closing doors, the mounting shell can be sealed to prevent concrete from splashing around during compression testing and causing injury to the inspection personnel.

[0009] According to the concrete testing device for hydraulic construction projects, the sliding groove and the adjusting groove are positioned correspondingly, and the number of sliding grooves and adjusting grooves is the same. By setting the adjusting groove and the sliding groove to correspond and have the same number, the clamping of the concrete by the rotation of the adjusting groove is more stable.

[0010] According to the concrete testing device for water conservancy construction projects, a protective shell is fixedly connected to the inner bottom wall of the mounting shell, and a motor is fixedly installed on the inner bottom wall of the mounting shell. The motor is located inside the protective shell, and the output end of the motor passes through the protective shell and is fixedly connected to the bottom center of the rotating disk. By setting up the protective shell, the motor is protected from being hit by concrete fragments during inspection, and concrete dust is prevented from entering the motor and thus affecting the normal operation of the rotating disk driven by the motor.

[0011] According to the concrete testing device for hydraulic construction projects, a limiting ring is rotatably connected to the bottom of the rotating disk, and the outer surface of the limiting ring is fixedly connected to the inner wall of the mounting shell. By setting the limiting ring, the rotating disk is limited, thereby reducing its weight and making its operation more stable.

[0012] The beneficial effects of this utility model are as follows: By setting a fixed plate, a rotating plate, and a clamping plate, the rotating plate drives the adjusting groove when it rotates, which in turn moves the moving column along the adjusting groove. The sliding block is limited by the sliding groove, so that the moving column and the sliding block move along the sliding groove. At the same time, the clamping plate moves along the sliding groove, so that the sliding groove makes synchronous opposite or separate movements. The concrete block to be tested is pushed to the center of the test and clamped. By setting a sliding rod, a clamping block, and a spring, the clamping plate makes the clamping block contact the concrete block when clamping it. The spring squeezes the clamping block, thereby further clamping the concrete block and strengthening the clamping effect.

[0024] The clamping plate 6 has several sliding rods 11 slidably connected inside. A clamping block 12 is fixedly connected to one end of the sliding rod 11 adjacent to the clamping block 12. A limit plate 14 is fixedly connected to one end of the sliding rod 11 away from the clamping block 12. A spring 13 is sleeved on the outer surface of the sliding rod 11. The two ends of the spring 13 are fixedly connected to the clamping block 12 and the clamping plate 6 respectively. The springs 13 do not contact each other.

[0025] The clamping blocks 12 are made of rubber and are trapezoidal in shape. The top surface of the mounting shell 1 is fixedly equipped with a detection display 18. The clamping blocks 12 do not contact each other.

[0026] The outer surface of the mounting shell 1 has a placement opening 21. The two sides of the placement opening 21 are hinged with a closing door 19. When the closing door 19 is closed, it fits into the outer surface of the mounting shell 1. A pull handle 20 is fixedly installed on the outer surface of the closing door 19. The pull handle 20 is made of rubber.

[0027] The sliding groove 8 and the adjusting groove 7 are positioned correspondingly, and the number of sliding grooves 8 and the adjusting groove 7 are the same. The bottom surface of the clamping plate 6 is in contact with the end face of the fixed plate 2.
