Description

Technical Field

[0001] This utility model relates to the field of pouring quality testing technology, specifically to a concrete pouring quality testing instrument. Background Technology

[0002] Concrete pouring is a crucial step in construction engineering. It refers to the process of pouring concrete from a mixer into a mold or construction site, followed by vibration, leveling, and curing to create a predetermined shape. To ensure that the poured concrete forms a product with the correct shape and structural strength that meets design requirements, the thickness and levelness of the concrete must be checked during pouring. This testing requires the use of a concrete pouring quality testing instrument.

[0003] The utility model patent with authorization announcement number CN219038902U discloses a concrete pouring quality tester, which can perform concrete thickness detection and levelness detection. However, it still has the following problems: When performing depth detection, the second electric telescopic rod extends and pushes the test rod into the concrete until it is inserted to the bottom. Then, the thickness of the concrete is characterized by the scale lines on the test rod. However, there is no reference surface in this process, which makes it impossible for the test rod to be inserted vertically into the concrete, thus affecting the detection accuracy.

When the first telescopic rod is in its shortest state, the bottom end of the first telescopic rod is flush with the bottom end of the scraper. A leveling plate is arranged parallel to the bottom of the support plate. The leveling plate can move parallel to or away from the support plate. When the leveling plate is attached to the bottom surface of the support plate, the bottom surface of the scraper is flush with the bottom surface of the leveling plate.

[0008] Optionally, the leveling disc is a disc and is coaxially arranged with the support disc. The leveling disc has multiple scraping holes, each corresponding to a scraper cylinder. The scraper cylinder slides with the leveling disc through the corresponding scraping hole, and the diameter of the scraping hole matches the outer diameter of the scraper cylinder.

[0009] Optionally, a connecting cylinder is coaxially protruding from the top surface of the locking disc. The connecting cylinder is rotatably engaged with the base disc. A cylindrical groove is coaxially formed on the top surface of the base disc. The diameter of the groove is larger than the outer diameter of the connecting cylinder. The top of the connecting cylinder is slightly higher than the bottom of the groove. A fixing ring is coaxially embedded in the groove. The outer diameter of the fixing ring matches the diameter of the groove. The fixing ring is coaxially and detachably connected to the top of the connecting cylinder.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] This utility model provides a concrete pouring quality testing instrument. By setting a support plate with multiple first telescopic rods on it and graduation lines at the bottom of the first telescopic rods, the device can perform concrete pouring depth testing. Simultaneously, by setting a slide rail, a sliding plate, second telescopic rods, and a scraper, the device can perform concrete pouring levelness testing. Furthermore, by setting a scraper cylinder with its inner diameter matching the diameter of the bottom of the first telescopic rods, during depth testing, the bottom of the first telescopic rod extends from the scraper cylinder and inserts into the concrete. After testing, it gradually retracts into the scraper cylinder. During retraction, due to the dimensional relationship, the scraper cylinder can scrape off the concrete adhering to the first telescopic rod, thus cleaning it promptly and effectively. During levelness testing, the scraper cylinder can be inserted into the concrete to structurally fix the device to the concrete, preventing slippage during levelness testing and affecting testing accuracy. Furthermore, the shortest retracted first telescopic rod can precisely seal the inner hole of the scraper cylinder, thus preventing concrete from penetrating into the scraper cylinder. In addition, a leveling plate and a lock are added. The device is configured to allow the leveling disc to move parallel to or away from the support disc, with a specific positional relationship between the two. During depth testing, the leveling disc is moved until its bottom surface is flush with the bottom surface of the scraper cylinder and fixed using a locking component. At this point, the bottom surface of the leveling disc is pressed against the concrete surface, providing a horizontal reference plane to ensure the first telescopic rod can be vertically inserted into the concrete. During levelness testing, the locking component is unlocked, allowing the leveling disc to move automatically. The device is then placed on the concrete surface from top to bottom and gradually pressed down, during which the scraper cylinder gradually inserts into the concrete. The leveling plate gradually approaches the support plate until they are in contact, at which point the bottom surface of the leveling plate is also in contact with the concrete surface. At this point, the bottom surface of the scraper is flush with the bottom surface of the leveling plate, i.e., in contact with the concrete surface. The length of the second telescopic rod is then adjusted, and the slide plate slides along the rail to drive the scraper in a circular motion, thus detecting the levelness of the concrete. Through the coordination of these features, this concrete pouring quality tester effectively solves the problem of existing concrete pouring quality testers being unable to guarantee the verticality of the test rod during depth testing.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0028] Example

[0029] Please refer to Figures 1 to 8This embodiment provides a concrete pouring quality testing instrument, including a support plate 10. The support plate 10 has multiple first telescopic rods 11 vertically arranged on it. The bottom sidewall of each first telescopic rod 11 has axially spaced scale lines 111. A slide rail 12 is laid on the sidewall of the support plate 10, and a slide plate 13 is slidably connected to the slide rail 12. The slide plate 13 is connected to a second telescopic rod 14, and a scraper 15 is provided at the outer end of each second telescopic rod 14. The instrument also includes multiple scraper cylinders 20, each corresponding to one of the first telescopic rods 11 and coaxially fitted onto the bottom end of the corresponding first telescopic rod 11. The inner diameter of each scraper cylinder 20 matches the diameter of the bottom end of the first telescopic rod 11. The top end of the cylinder 20 is fixedly connected to the support plate 10. When the first telescopic rod 11 is in its shortest state, the bottom end of the first telescopic rod 11 is flush with the bottom end of the scraper cylinder 20. The third part includes a leveling plate 30, which is arranged parallel to the bottom of the support plate 10. The leveling plate 30 can move parallel to or away from the support plate 10. When the leveling plate 30 is attached to the bottom surface of the support plate 10, the bottom surface of the scraper 15 is flush with the bottom surface of the leveling plate 30. The fourth part includes a locking component, which can fix the leveling plate 30 to the support plate 10. When fixedly connected, the bottom surface of the leveling plate 30 is flush with the bottom surface of the scraper cylinder 20.

[0030] The concrete pouring quality testing instrument provided in this embodiment, by setting a support plate 10, with multiple first telescopic rods 11 mounted on the support plate 10, and scale lines 111 set at the bottom of the first telescopic rods 11, enables the device to perform concrete pouring depth testing. Simultaneously, by setting a slide rail 12, a sliding plate 13, a second telescopic rod 14, and a scraper 15, the device can perform concrete pouring levelness testing. Furthermore, by setting a scraper cylinder 20, with its inner diameter matching the diameter of the bottom end of the first telescopic rods 11, during depth testing, the bottom end of the first telescopic rod 11 extends out from the scraper cylinder 20 and inserts into the concrete for testing. Upon completion and during recycling, it gradually retracts into the scraper cylinder 20. During this retraction, due to the size relationship between the two, the scraper cylinder 20 can scrape off the concrete adhering to the first telescopic rod 11, thereby cleaning the first telescopic rod 11 in a timely and effective manner. When performing levelness testing, the scraper cylinder 20 can be inserted into the concrete to structurally fix the device to the concrete, preventing the device from slipping during the levelness testing process and affecting the testing accuracy. Furthermore, the first telescopic rod 11 at its shortest retraction can precisely seal the inner hole of the scraper cylinder 20, thereby preventing concrete from penetrating into the scraper cylinder 20. Based on this, by setting the leveling plate 30 and... The locking component allows the leveling plate 30 to move parallel to or away from the support plate 10, and sets a specific positional relationship between the two. During depth testing, the leveling plate 30 is moved until its bottom surface is flush with the bottom surface of the scraper cylinder 20 and fixed by the locking component. At this point, the bottom surface of the leveling plate 30 is pressed against the concrete surface, providing a horizontal reference plane to ensure that the first telescopic rod 11 can be vertically inserted into the concrete. During levelness testing, the locking component is unlocked, allowing the leveling plate 30 to move automatically. The device is then placed on the concrete surface from top to bottom and gradually pressed down, during which the scraper cylinder 20 gradually inserts into the concrete. The leveling plate 30 gradually approaches the support plate 10 until it is in contact with the support plate 10. At this point, the bottom surface of the leveling plate 30 is also in contact with the concrete surface, and the bottom surface of the scraper 15 is flush with the bottom surface of the leveling plate 30, i.e., in contact with the concrete surface. Then, the length of the second telescopic rod 14 is adjusted, and the slide plate 13 is slid along the slide rail 12 to drive the scraper 15 to make a circular motion, which can detect the levelness of the concrete. Through the cooperation of the above features, the concrete pouring quality tester can effectively solve the problem that the existing concrete pouring quality tester cannot guarantee the verticality of the test rod when performing depth detection.

[0031] It should be noted that the first telescopic rod 11 and the second telescopic rod 14 mentioned above can be any type of controllable telescopic rod in the prior art, such as pneumatic telescopic rod, hydraulic telescopic rod, electric telescopic rod, etc.

[0032] It should be noted that the cooperation between the slide rail 12 and the slide plate 13 can be any kind of mechanical sliding cooperation in the prior art, or any kind of electromagnetic sliding cooperation in the prior art, as long as the slide plate 13 can slide along the slide rail 12.

[0033] To further describe the specific structure of the locking assembly, the support plate 10 includes a stacked base plate 16 and a locking plate 40, which are coaxially rotatably connected to the base plate 16. A locking pin 41 is coaxially connected to the locking plate 40, with its top end penetrating the base plate 16 and having a handle 411. The locking plate 40 has multiple arc-shaped sliding holes 42, and the scraper cylinder 20 corresponds to and slides with each of the sliding holes 42. The top end of the scraper cylinder 20 is fixedly connected to the base plate 16. The locking plate 40 also has multiple arc-shaped locking holes 43, with the starting width of each locking hole 43 being greater than its ending width. The locking assembly includes multiple locking rods 44, each corresponding to and slidingly engaging with a locking hole 43. The diameter of each locking rod 44 matches the initial width of the locking hole 43. Each locking rod 44 has a locking section 441, the diameter of which matches the final width of the locking hole 43. The bottom end of each locking rod 44 is vertically and fixedly connected to the leveling plate 30, and the top end of each locking rod 44 penetrates the base plate 16 and slidesly engages with it. When the bottom surface of the leveling plate 30 is flush with the bottom surface of the scraper cylinder 20, the locking section 441 is flush with the corresponding locking hole 43.

[0034] With the above setup, by turning the locking pin 41 with the handle 411, the locking disc 40 can be driven to rotate synchronously, thereby driving the sliding hole 42 and the locking hole 43 opened on it to rotate synchronously, while the scraper 20 and the locking rod 44 remain stationary. Therefore, they slide along the sliding hole 42 and the locking hole 43 respectively. When the locking rod 44 is aligned with the beginning of the locking hole 43, the leveling disc 30 can slide freely along the axial direction through the locking rod 44. When the locking section 441 is aligned with the locking hole 43, the locking disc 40 is rotated, causing the locking section 441 to slide to the end of the locking hole 43. At this time, the locking rod 44 can no longer slide along the axial direction, thus locking the position of the locking disc 40.

[0035] In order to clean the concrete adhering to the outer wall of the scraper cylinder 20 after the concrete leveling test, the leveling plate 30 is a disc and is coaxially arranged with the support plate 10. The leveling plate 30 has a plurality of scraping holes 31, each of which corresponds to a scraper cylinder 20. The scraper cylinder 20 slides with the leveling plate 30 through the corresponding scraping holes 31, and the diameter of the scraping holes 31 matches the outer diameter of the scraper cylinder 20.

[0036] With the above settings, after the concrete leveling test is completed, the device is gradually lifted upwards. During the process, the scraper cylinder 20 is gradually pulled out of the concrete. At the same time, the leveling plate 30 slides downwards relative to the scraper cylinder 20 under the action of gravity, thereby scraping off the concrete attached to the outer wall of the scraper cylinder 20.

[0037] It should be noted that when the leveling disc 30 is stuck by the concrete adhering to the outer wall of the scraper 20, the leveling disc 30 can be manually slid back and forth to remove the adhering concrete.

[0038] To further explain the rotating connection structure between the locking disc 40 and the base disc 16, a connecting cylinder 401 is coaxially protruded from the top surface of the locking disc 40. The connecting cylinder 401 is rotatably engaged with the base disc 16. A cylindrical groove 161 is coaxially formed on the top surface of the base disc 16. The diameter of the groove 161 is larger than the outer diameter of the connecting cylinder 401. The top of the connecting cylinder 401 is slightly higher than the bottom of the groove 161. A fixing ring 162 is coaxially embedded in the groove 161. The outer diameter of the fixing ring 162 matches the diameter of the groove 161. The fixing ring 162 is coaxially and detachably connected to the top of the connecting cylinder 401.

[0039] To make the handle 411 easy to apply force and use, the handle 411 is rod-shaped and T-shaped with the locking post 41, and the outer wall of the handle 411 is provided with anti-slip texture.

[0040] To further improve the scraping effect on the inner wall of the scraper cylinder 20, an elastic scraper ring 21 is coaxially sleeved at the bottom end of the scraper cylinder 20, and the bottom end of the first telescopic rod 11 is coaxially slidably sleeved in the elastic scraper ring 21 and is interference-fitted with the elastic scraper ring 21.

[0041] To ensure the stability of the device's position during the levelness detection process, the outer diameter of the scraper cylinder 20 is much larger than the diameter of the bottom end of the first telescopic rod 11.

[0042] To facilitate the insertion of the scraper 20 into the concrete, the bottom end of the scraper 20 is provided with a penetration cone (not shown).

[0043] Preferably, all the first telescopic rods 11 are arranged in a ring at uniform intervals with the axis of the support plate 10 as the axis.

[0044] Preferably, the second telescopic rod 14 is arranged radially along the support plate 10.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
