Description

Technical Field

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

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it hardens. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. During concrete pouring, the quality of the concrete is very important, as it can not only ensure the quality of the concrete but also prevent engineering quality problems from occurring.

[0003] A concrete testing instrument, as described in application number CN202322561680.1, includes a base plate. Support seats are bolted to the four corners of the lower surface of the base plate. A display is bolted to the front left side of the upper surface of the base plate, and a controller is bolted to the rear left side of the left surface of the base plate. A cable is glued to the connection between the display and the controller. This invention features a first lifting cylinder, a striking rod, and a detector. Activating the first lifting cylinder lowers the striking rod, which strikes the concrete road surface to test the compressive strength of the concrete. Simultaneously, the detector collects the test data, which helps solve the problem of poor concrete bearing capacity testing in existing solutions. However, this testing equipment requires continuous manual striking of the solidified concrete, resulting in high labor costs, low efficiency, and reduced accuracy of the test results. Furthermore, it has limited functionality, as it cannot promptly address protruding solid impurities on the surface of the solidified concrete.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a testing device for concrete pouring. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for concrete pouring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete pouring testing device, comprising a mold and a support frame, wherein the outer surface of the mold is provided with the support frame, and the inner surface of the support frame is fixedly connected with a striking mechanism, the inner wall of the support frame is fixedly connected with a leveling mechanism, and an ultrasonic testing instrument is provided on the top of the mold.

[0007] Preferably, the striking mechanism includes a base plate fixedly connected to one side of the outer surface of the support frame, and a groove is formed on the inner surface of the base plate. A toothed rail is slidably connected inside the groove, and a gear is meshed on one side of the toothed rail. The top of the gear is fixedly connected to the outside of the output end of the servo motor. A striking hammer is fixedly connected to one end of the toothed rail, and a groove is formed inside the right side of the base plate.

[0008] Preferably, the leveling mechanism includes a guide rod fixedly connected to the inner wall of the support frame, and a movable plate is slidably connected to the outer surface of the guide rod, with a scraper fixedly connected to the bottom of one side of the movable plate.

[0009] Preferably, a cylinder is fixedly connected to one side of the movable plate, and a drive rod is connected through the inner surface of the support frame.

[0010] Preferably, the drive rod is externally threaded with a nut seat, and an electric push rod is fixedly connected to the bottom of the nut seat.

[0011] Preferably, the bottom of the electric push rod is provided with an adjustment plate, and one side of the adjustment plate is fixedly connected to the telescopic plate.

[0012] Preferably, the bottom of the adjustment plate is fixedly connected to multiple identical detection heads, and the outer surface of the detection heads is fixedly connected with scale lines.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model replaces the method of manually tapping the outside of the mold when testing the concrete inside the mold by setting up a tapping mechanism and a leveling mechanism. The tapping mechanism can tap the outside of the mold continuously at the same frequency, which can reduce the adverse effects of low manual tapping frequency and weak rebound sound on the concrete strength. The automatic tapping of the tapping mechanism can make up for the deficiencies and improve the testing accuracy of the ultrasonic tester. After the concrete inside the mold has solidified, the leveling mechanism moves from one side of the top surface of the concrete to the other side. During the movement, the leveling mechanism scrapes away impurities and protrusions on the concrete surface, making the top outer surface of the concrete more flat, which not only improves the flatness but also facilitates subsequent engineering construction.

[0015] 2. By setting the drive rod and the scale lines on the outside of the detection head, this utility model allows the ultrasonic detector to move left and right on the top of the mold when the concrete is curing, thus expanding the detection range of the ultrasonic detector on the cured concrete inside the mold. When the concrete is not cured, the detection head can be inserted into the concrete for detection, improving the applicability of this device. The depth of the concrete can be seen intuitively through the scale lines. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 As shown, a concrete pouring testing device includes a mold 1 and a support frame 2. The support frame 2 is provided on the outer surface of the mold 1, and a striking mechanism 3 is fixedly connected to the inner surface of the support frame 2. A leveling mechanism 4 is fixedly connected to the inner wall of the support frame 2, and an ultrasonic detector 13 is provided on the top of the mold 1. Uncured concrete is poured into the mold 1. The support frame 2 consists of two sets of side plates and a top plate. The right side plate has a movable hole. The striking mechanism 3 strikes the outside of the mold 1 through the movable hole. The ultrasonic detector 13 has high accuracy in its test results.

[0023] like Figure 2As shown, the striking mechanism 3 includes a base plate 301 fixedly connected to one side of the outer surface of the support frame 2. The inner surface of the base plate 301 is provided with a groove 302. A toothed rail 303 is slidably connected inside the groove 302. A gear 304 is meshed with one side of the toothed rail 303. The top of the gear 304 is fixedly connected to the outside of the output end of the servo motor 305. A striking hammer 306 is fixedly connected to one end of the toothed rail 303. The right side of the base plate 301 is provided with a groove 302. The top left side of the base plate 301 is rotatably connected to the gear 304. The bottom of the toothed rail 303 is provided with a convex block that is consistent with the groove 302. The toothed rail 303 slides inside the groove 302 through the convex block. The servo motor 305 drives the striking hammer 306 at one end of the toothed rail 303 to strike the outside of the mold 1 at a certain frequency, which is convenient for the ultrasonic detector 13 to detect.

[0024] Furthermore, the leveling mechanism 4 includes a guide rod 401 fixedly connected to the inner wall of the support frame 2, and a movable plate 402 is slidably connected to the outer surface of the guide rod 401. A scraper 403 is fixedly connected to the bottom of one side of the movable plate 402. The guide rod 401 is symmetrically distributed on the inner surface of the movable plate 402, which plays a supporting and guiding role for the movable plate 402. The scraper 403 is triangular in shape, with one side being relatively sharp, to remove impurities from the surface of the cured concrete and keep the surface clean.

[0025] Furthermore, a cylinder 5 is fixedly connected to one side of the movable plate 402, and a drive rod 6 is connected through the inner surface of the support frame 2. A nut seat 7 is threadedly connected to the outside of the drive rod 6, and an electric push rod 8 is fixedly connected to the bottom of the nut seat 7. A driver is provided at one end of the drive rod 6. Under the action of the driver, the drive rod 6 drives the nut seat 7 to move outside the guide rod, ensuring the stability of the nut seat 7 when it moves.

[0026] Furthermore, an adjustment plate 9 is provided at the bottom of the electric push rod 8, and one side of the adjustment plate 9 is fixedly connected to the telescopic plate 10. Multiple identical detection heads 11 are fixedly connected to the bottom of the adjustment plate 9, and scale lines 12 are fixedly connected to the outer surface of the detection head 11. A control rod is provided inside the adjustment plate 9, which can uniformly adjust the extension length of the four sets of adjustment plates 9, so as to expand the detection range of uncured concrete. The detection head 11 detects the uncured concrete, and the outer surface of each set of detection head 11 is provided with the same scale lines, which is convenient for workers to check.

[0027] Working principle: When using this concrete pouring testing equipment, first pour concrete into the mold 1, place the support frame 2 on top of the mold 1, and before the concrete hardens, drive rod 6 moves nut seat 7 left and right. The control rod inside telescopic plate 10 moves the detection head 11 at the bottom of telescopic plate 10 to adjust its position as needed. At this time, electric push rod 8 at the bottom of nut seat 7 moves adjustment plate 9 downward, and detection head 11 enters the concrete to perform testing. The speed of concrete pouring can be visually judged through scale line 12. After confirming that the internal strength of the concrete is normal, the detection head 11 is removed. 1. After a period of curing, the servo motor 305 of the striking mechanism 3 is activated, causing the gear 304 on the top of the base plate 301 to drive the toothed rail 303 to move back and forth. The striking hammer 306 at one end of the toothed rail 303 strikes the outside of the mold 1. The ultrasonic detector 13 detects the concrete through the sound waves emitted by the striking. The results of the test are transmitted to the computer and recorded. Finally, the cylinder 5 is activated to drive the moving plate 402 of the leveling mechanism 4 to move back and forth outside the guide rod 401. The scraper 403 contacts the concrete surface to ensure that the concrete surface tends to be flat. This is the working principle of the concrete pouring testing equipment.
