Description
Technical Field
[0001] The utility model relates to the technical field of concrete testing, and specifically relates to an auxiliary device for concrete test sampling in construction monitoring. Background Art
[0002] Concrete is an engineering structural material composed of a binder and aggregates, and it has a wide range of applications in the field of civil engineering. After construction is completed, in order to ensure the quality and strength of concrete, it is usually necessary to supervise and test it. A rebound hammer is a commonly used testing tool that can preliminarily evaluate the strength of concrete. However, when the strength test results do not meet the standards or more accurate data is required, the core sampling test method needs to be adopted.
[0003] The traditional core sampling test method is to manually operate a drilling machine and use a drill bit with a sleeve to drill samples on the concrete surface. This method has some deficiencies: during the cutting process, the drill bit may be unstable due to excessive force, and when the sleeve is pulled out, the concrete sample is likely to fall off, be damaged, or get stuck inside the sleeve, causing difficulties in sample collection.
[0004] To solve these problems, we have designed a new type of auxiliary device for concrete testing in construction monitoring. This device aims to improve the stability of core sampling testing and the integrity of samples, thereby improving the accuracy and efficiency of testing. Summary of the Utility Model

[0008] The concrete test sampling auxiliary device for construction monitoring provided by the present utility model further includes other technical features. Among them, the movable support includes a bottom frame, a fixed rod arranged on the bottom frame, a mounting plate arranged at the top of the fixed rod, and a movable plate sliding on the fixed rod. Upper and lower extension sections are respectively arranged on the side surface of the movable plate.

[0009] The concrete test sampling auxiliary device for construction monitoring provided by the present utility model further includes other technical features. Among them, a clamping groove is formed on the inner edge of the top of the mating plate. A clamping rod is arranged laterally on the movable block, and the clamping rod cooperates with the clamping groove.

[0010] The concrete test sampling auxiliary device for construction monitoring provided by the present utility model further includes other technical features. Among them, the movable support further includes a mounting rod, a restraint cylinder, and a rotating wheel. The mounting rod is in a lead screw structure and penetrates through the mounting plate, the movable plate, and the bottom frame. A through hole with an internal thread structure on the movable plate cooperates with the lead screw of the mounting rod. A through hole without an internal thread on the inner side is arranged on the mounting plate and sleeved and cooperated with the mounting rod. The rotating wheel is arranged at the top of the mounting rod and on the upper side of the mounting plate. By rotating the rotating wheel, the mounting rod is driven to rotate.

When the core drilling cylinder reaches the predetermined depth, the electric push rod will push the connecting rod, so that the buffer block applies pressure to the concrete core to ensure its fixation.
[0016] The clamping block is located on the upper side of the concrete core. When the core drill completes coring and is ready to reset, the clamping connection between the constraint plate and the mating plate is released, and the constraint plate rotates with the core drill under the action of the mating plate, ensuring the stable position of the concrete core inside the core drill and preventing it from falling during the extraction process. After the core drill is reset, pressure is applied to the concrete core through the clamping block, causing it to slide out of the core drill and completing the coring process.
[0017] After coring is completed, the support cylinder, deformation block, and support block in the device work together to support the reset of each structure, enabling the entire device to quickly return to its initial state and facilitating the operator to quickly remove the concrete core. Through the precise cooperation of these components, this device not only ensures the stability of the coring process but also improves the speed and convenience of coring.

Detailed Embodiment
[0024] To make the purpose, principle, and structure of the present invention clearer, the following further elaborates with reference to the drawings and specific embodiments.
[0025] The present invention provides a concrete test sampling auxiliary device for construction monitoring, as Figure 1 - Figure 5As shown in the figure, it includes a chassis 1. The chassis 1 is a rectangular frame with rotatable rollers on its side. The chassis 1 can be driven to move and place through the rotatable rollers. On the upper side of the chassis 1, there is a main body assembly. The main body assembly includes fixing rods 2 symmetrically and fixedly installed on the upper side of the chassis 1. The fixing rods 2 are circular rods. On the upper side of the fixing rods 2, there is an installation plate 3 fixedly installed. The installation plate 3 is a rectangular plate. At the center position of the installation plate 3, there is an installation rod 4 passing through it. The installation rod 4 is a circular threaded rod. On the upper side of the installation plate 3, there is a rotating wheel 5 and the rotating wheel 5 is fixedly connected to the top surface of the installation rod 4. The rotating wheel 5 is a circular wheel, and there is a handle on its circumference. By operating the handle to rotate the rotating wheel 5, the installation rod 4 can be driven to perform a rotational motion. The middle part of the installation rod 4 is threadedly sleeved with a movable plate 6. The two ends of the movable plate 6 are movably sleeved on the fixing rods 2 to achieve vertical up and down sliding. On one side surface of the movable plate 6, there are also an upper extension section 26 and a lower extension section 27 respectively. The upper extension section 26 is fixedly connected to the motor 8, and the lower extension section 27 is fixedly connected to the matching plate 12.
[0026] The installation rod 4 is threadedly engaged with the movable plate 6 and is restricted by the fixing rods 2 to move. On the lower side of the installation rod 4, there is a restraint cylinder 7 movably sleeved and the restraint cylinder 7 is fixedly connected to the chassis 1. The restraint cylinder 7 is a circular cylinder, which is used to limit the movement range of the movable plate 6 on the installation rod 4 and the fixing rods 2.
[0027] On the upper extension section 26 of the movable plate 6, there is a motor 8 fixedly installed. On the lower side of the motor 8, there is a core sampling cylinder 9 fixedly connected to the output shaft of the motor 9. The core sampling cylinder 9 is a hollow cylindrical cylinder. The upper end of the cylindrical cylinder is closed and the lower end is open, and the circumference of the open side is serrated. The motor 8 can drive the core sampling cylinder 9 to perform a rotational cutting motion.
[0028] Furthermore, on the side surface of the core sampling cylinder 9, there is an auxiliary module. The auxiliary module includes: rectangular slots 10 symmetrically opened on the side surface of the core sampling cylinder 9; on the outside of the core sampling cylinder 9 and at the upper end of the slots 10, there is a restraint plate 11 movably sleeved. The restraint plate 11 is an annular plate. On the outside of the restraint plate 11, there is a matching plate 12 movably sleeved and the matching plate 12 is fixedly connected to the movable plate 6 through the lower extension section 27; the matching plate 12 is an annular plate with an "L"-shaped cross section. The restraint plate 11 abuts against the core sampling cylinder 9 and the matching plate 12 but is not fixedly connected, and the restraint plate 11 can be limited in rotation under the abutment of the core sampling cylinder 9 and the matching plate 12 on both sides. There are two cavities on both sides of the restraint plate 11, and there are connecting rods 16, elastic bodies and push rods 21 in the cavities.
[0029] The connecting rod 16 vertically penetrates through the cavity. An active block 17 is sleeved in the middle of the connecting rod 16. The active block 17 is arranged at the upper opening of the cavity and has a width greater than the opening of the cavity, so as to limit the connecting rod 16 in the vertical direction. The connecting rod 16 is slidably sleeved with the active block 17. A control block 25 is fixedly connected to the top of the connecting rod 16. The lower end surface of the control block 25 has the same shape and area as the upper end surface of the active block 17. An elastic support cylinder 18 with a wavy bend is also sleeved between the control block 25 and the active block 17. The support cylinder 18 is composed of an elastic body, which provides a supporting force for the connecting rod 16 in the static state, and can be deformed and compressed when the control block 25 is pressed down, so as to accumulate elastic potential energy to provide an upward sliding driving force for the connecting rod 16 when the device resets. A clamping block 13 is fixedly connected to the bottom of the connecting rod 16. The shape of the clamping block 13 matches the shape of the slot 10. A buffer block 14 is also arranged on the side of the clamping block 13 close to the slot. The buffer block 14 is a rectangular block made of rubber, and the buffer block 14 can squeeze the fixed core column.
[0030] The elastic body includes a deformation block 19 and a support block 20. The deformation block 19 is a hollow structure with a flat surface on one side and an arc surface on the other side. The support block 20 is a polygonal block with a wavy bend. The flat surface of the deformation block 19 abuts against the side surface of the cavity close to the core-taking cylinder 9, and the arc surface abuts against the connecting rod 16. The flat surface is used to increase the friction force between the deformation block 19 and the cavity of the constraint plate 11 to form a limit. The arc surface is used to form a limit by giving a slight friction force to the connecting rod 16, and at the same time, the connecting rod 16 can break through the static friction force under a slight applied force to realize sliding in the cavity. And when the elastic body deforms, the arc surface can be compressed into a flat surface, increasing the friction force on the connecting rod 16 during deformation. The support block 20 is horizontally arranged in the middle of the hollow structure of the deformation block 19, which provides an internal supporting force for the deformation block 19 of the hollow structure to prevent the deformation block 19 from collapsing under slight force. At the same time, the elastic material and wavy bend of the support block 20 ensure that it can be fully compressed and deformed when deformation is required.
[0031] A push rod 21 is also fixedly installed in the constraint plate on the inner wall of the connecting groove 15 of the cavity, which is far away from the deformation block 19. The push rod 21 can be an electric push rod. A matching block 22 is fixedly installed at the end of the push rod 21 close to the connecting rod 16. The matching block 22 is a circular block made of rubber. The push rod 21 can push the matching block 22 to squeeze the side surface of the connecting rod 16. A card slot 23 penetrating through it is opened on the side surface of the matching plate 12 corresponding to the position of the active block 17. The card slot 23 is a circular slot. A clamping rod 24 is fixedly installed on the side surface of the active block 17 and the clamping rod 24 is clamped inside the card slot 23. The clamping rod 24 is a circular rod, and the clamping rod 24 can make the constraint plate 11 and the matching plate 12 be clamped and fixed together.
[0032] Working principle of the utility model:
[0033] During use, the motor 8 drives the core barrel 9 to rotate. The rotating wheel 5 rotates the mounting rod 4 and the movable plate 6 engages in a threaded manner. The mounting rod 4 is restricted by the restraint cylinder 7. When the movable plate 6 moves, the core barrel 9 performs a cutting and coring operation. At this time, the clamping rod 24 is clamped inside the card slot 23, causing the restraint plate 11 and the mating plate 12 to be fixedly clamped together. The restraint plate 11 provides a certain degree of restraint and stability to the core barrel 9. When the core barrel 9 reaches the coring completion position, the push rod 21 then pushes the mating block 22 to squeeze against the side of the connecting rod 16, causing the connecting rod 16 to slide and deform the deformation block 19 and the support block 20 inside the connecting slot 15. The clamping block 13 then moves to the position inside the slot 10. At this time, the buffer block 14 is pressed and fixed to the side of the concrete core. The protruding position of the clamping block 13 is located above the concrete core. At the same time, the clamping rod 24 is pulled out of the card slot 23. The rotation of the core barrel 9 causes the restraint plate 11 to be constrained and rotated by the mating plate 12. The rotating wheel 5 drives the movable plate 6 to move upward to complete the coring operation. Press the clamping block 13 to slide inside the slot 10 to extrude the concrete core out of the core barrel 9, and directly extract the concrete core to complete the operation. Subsequently, under the support of the support cylinder 18, the connecting rod 16 is reset. Rotate the clamping block 13 to make the restraint plate 11 rotate in place inside the mating plate 12. Control the electric push rod 21 to reset, and under the support of the deformation block 19 and the support block 20, the clamping rod 24 is clamped inside the card slot 23 to reset.
[0034] The above is only the specific implementation manner of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by this utility model, according to the technical solution and the new concept of this utility model, with equivalent replacement or change, should be covered within the protection scope of this utility model.
