Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, in particular to a concrete detection device for municipal engineering construction. Background Art

[0002] In municipal engineering construction, concrete is a widely used building material, and its quality and performance are directly related to the safety and durability of the project. Concrete slump is an important indicator for evaluating the fluidity and plasticity of concrete, and is of great significance for ensuring the quality of concrete construction and engineering safety.

[0003] Concrete slump refers to the vertical drop distance of concrete when the mixture expands and reaches a stable state after vibration under standard test conditions. This indicator directly reflects the fluidity and plasticity of concrete and is an important basis for guiding concrete construction and controlling concrete quality. Reasonable slump helps to ensure that concrete is easy to pour, vibrate and compact during construction, avoiding construction difficulties caused by insufficient fluidity and segregation and water seepage caused by excessive fluidity.

[0004] Traditional concrete slump detection is mainly carried out manually, and the specific steps include placing the slump cone, loading, tamping, scraping, lifting the cone and measuring. A problem may be encountered during the tamping process. The slump cone is conical, with a wide bottom and a narrow top. It is not convenient to stir and tamp the bottom side during the tamping process. The purpose of the slump test is to evaluate the fluidity of concrete, and the accurate evaluation of the fluidity depends on the uniform mixing of the various parts of the concrete. If the concrete on the bottom side is not sufficiently mixed, the slump value obtained from the test may not truly reflect the overall fluidity of the concrete, resulting in deviations in the test results. For this reason, a concrete detection device for municipal engineering construction that solves the above problems is proposed. Summary of the invention

[0023] Working principle: During the working process, the staff can bring the device to the workplace, and then place the conical table 2 on the top surface of the supporting plate 1. Then, the staff can start the motor 1304 in the second driving mechanism 13. The output end of the motor 1304 drives the first limit plate 1305 to rotate. Since the first limit plate 1305 is slidingly connected with the first limit groove at the end of the first worm gear 1303, the first worm gear 1303 will rotate accordingly, thereby driving the first rotating rod 601 to rotate.

[0024] In addition, after the concrete mixing is completed, the staff can immediately turn on the electric push rod 902, so that the electric push rod 902 drives the third connecting plate 903 to move upward, thereby driving the movable plate 4 to move upward. At this time, since the first clamping plate 607 and the second clamping plate 608 are in a clamping state on the conical table 2, the conical table 2 will be driven to move upward, making it easier to pour the concrete inside the conical table 2 onto the supporting plate 1.

The inner bottom surface of the third mounting box 1201 is rotatably connected with a third rotating rod 1203 and a third turbine 1204 is installed on one side of an outer wall of the third rotating rod 1203. A second limiting plate 1205 is installed on the top of the third rotating rod 1203. A third limiting groove is configured on the bottom of the second bevel gear 805. A fixing plate 20 is symmetrically installed on the top surface of the limiting ring 3. A connecting groove is configured on the top surface of the fixing plate 20 and an L-shaped plate 21 is slidably connected to the inner wall of the connecting groove. An end of the L-shaped plate 21 away from the fixing plate 20 is fixedly connected to the second mounting box 801. A second mounting groove is configured on one side of an outer wall of the L-shaped plate 21 and a third spring 22 is installed on the inner wall of the second mounting groove.A second limiting rod 23 is installed at one end of the third spring 22 away from the second installation slot, a second limiting hole is configured on one side of the outer wall of one of the fixing plates 20, and one end of the second limiting rod 23 away from the third spring 22 passes through the second limiting hole and the end is located outside the second limiting hole.

[0026] Working principle: During the working process, if the staff needs to move the position of the motor 1304, the staff can press the first limit rod 19. At this time, the first limit rod 19 will drive the first spring 18 to slide along the first mounting groove, thereby disengaging from the first limiting hole, and then move the first connecting plate 15 upward, thereby driving the motor 1304 to move upward. At this time, the second connecting plate 16 slides along the inner wall of the limit box 17 until the first limit rod 19 is on the side of the first limiting hole above. At this time, the first spring 18 will return to its natural state, thereby driving the first limit rod 19 to move in the direction away from the first mounting groove until the first spring 18 returns to its natural state. At this time, the first limit rod 19 is located on the outside of the first limiting hole, thereby fixing the second connecting plate 16 to the inside of the limit box 17, thereby fixing the motor 1304.

[0027] Then the staff can place the second installation box 801 on the top of the conical platform 2, and then align the L-shaped plate 21 with the connecting groove, and then use the fingers to push the scraper 1005 to move in the direction close to the vibrating rod 7. At this time, the second spring 1002 is in a compressed state, and then the scraper 1005 can be placed along the top of the conical platform 2. At this time, the second spring 1002 will restore its natural shape without the resistance of the fingers, driving the rubber piston 1003 and the connecting rod 1004 to move in the direction away from the vibrating rod 7, so that it can stretch out inside the conical platform 2, which is convenient for stirring the cement mortar inside the conical platform 2, increasing the stirring area and intensity, and at the same time, it can also scrape off the concrete attached to the inside of the conical platform 2 (the second spring 1002 restores its natural state, and the scraper 1005 will conflict with the inner wall of the conical platform 2). Here, the upper and lower sides of the end of the scraper 1005 are provided with inclined surfaces, which are in contact with the conical platform 2 is adapted to the inner wall of the L-shaped plate 21. In addition, when the vibrating rod 7 moves downward, the L-shaped plate 21 will move along the connecting groove until the second limiting rod 23 hits the fixing plate 20. Then the staff can press the second limiting rod 23 until the second limiting rod 23 drives the third spring 22 to move along the inner wall of the second mounting groove until the second limiting rod 23 is located inside the second mounting groove. Then, the second mounting box 801 continues to be pressed downward until the second limiting rod 23 is located on the side of the second limiting hole. At this time, the third spring 22 will return to its natural state, driving the second limiting rod 23 to move in the direction away from the second mounting groove until the second limiting rod 23 is located outside the second limiting hole, so that the L-shaped plate 21 can be fixed to the inside of the connecting groove. At this time, when the second mounting box 801 moves downward, it will drive the second bevel gear 805 to move downward until the second limiting plate 1205 is located inside the third limiting groove.

[0028] Then the staff can continue to turn on the motor 1304, so that the motor 1304 drives the third worm 1202 to rotate, thereby driving the third worm wheel 1204 to rotate, thereby driving the third rotating rod 1203 to rotate, thereby driving 1205 to rotate. Since the second limit plate 1205 is slidingly connected to the third limit groove at this time, and the second limit plate is located inside the third limit groove, the second limit plate 1205 will drive the second bevel gear 805 to rotate while rotating, thereby driving the first bevel gear 804 to rotate, thereby driving the second turbine 802 to rotate, thereby driving the vibrating rod 7 to rotate, thereby driving the connecting rod 1004 and the scraper 1005 to rotate, and stirring the concrete inside the conical table 2.

[0029] Embodiment 3: The leveling mechanism 11 includes a screw 1101 threadedly connected to the four corners of the top surface of the supporting plate 1, a handle 1102 is installed at the top of the screw 1101, and a pointed tip is constructed at the end of the screw 1101 away from the handle 1102, and a level bubble 1103 is installed on the four sides of the outer wall of the supporting plate 1.

[0030] Working principle: During the working process, if the staff is testing on an uneven ground, the staff can first determine whether the supporting plate 1 is in a horizontal state by observing the positions of four level bubbles 1103. If the bubbles in the level bubble 1103 deviate from the central position, it means that the supporting plate 1 needs to be leveled. Then, according to the direction in which the bubbles deviate, the staff adjusts its height by rotating the handle 1102 of the screw 1101 at the corresponding position. If the bubble deviates to one side, rotate the screw 1101 on that side to make it rise (or fall, depending on the specific situation) until the bubble returns to the central position of the level bubble 1103. Repeated adjustment and confirmation: During the adjustment process, the staff needs to repeatedly observe the position of the level bubble 1103, and make multiple adjustments as needed until the supporting plate 1 is horizontal in four directions.

[0031] Working step one: during the working process, after placing the supporting plate 1 on the ground, the staff observes the positions of the four level bubbles 1103 to determine whether the supporting plate 1 is in a horizontal state. If the bubble in the level bubble 1103 deviates from the central position, it means that the supporting plate 1 needs to be leveled. Then, according to the direction in which the bubble deviates, the staff adjusts its height by rotating the handle 1102 of the screw 1101 at the corresponding position. If the bubble deviates to one side, rotate the screw 1101 on that side to make it rise (or fall, depending on the specific situation) until the bubble returns to the central position of the level bubble 1103. Repeated adjustment and confirmation: during the adjustment process, the staff needs to repeatedly observe the position of the level bubble 1103 and make multiple adjustments as needed until the supporting plate 1 is horizontal in all four directions.

[0032] Working step two: Then during the working process, the staff can place the conical table 2 on the top surface of the supporting plate 1, and then start the motor 1304 in the second driving mechanism 13. The output end of the motor 1304 drives the first limit plate 1305 to rotate. Since the first limit plate 1305 is slidingly connected with the first limit groove at the end of the first worm 1303, the rotation of the first worm 1303 drives the first turbine 1302 meshing therewith to rotate, thereby driving the first rotating rod 601 to rotate, and the rotation of the first rotating rod 601 drives the spur gear 602 to rotate. Since the spur gear 602 is meshed with the first rack 603, and the spur gear 602 is meshed with the second rack 606, when the spur gear 602 rotates, it will drive the first rack 603 and the second rack 606 to move toward each other, thereby driving the first clamping plate 607 and the second clamping plate 608 to move toward each other to clamp the limit ring 3. It should be noted that the limit ring 3 is installed in the middle of the conical table 2, and the distance from the bottom of the conical table 2 and the distance from the top of the conical table 2 are consistent, so when the staff puts the conical table 2 upside down, the conical table 2 can also be clamped. After clamping, the concrete to be tested can be poured into the inside of the conical table 2.

[0033] Working step three: After the clamping is completed, the staff can move the position of the motor 1304, and the staff can press the first limit rod 19. At this time, the first limit rod 19 will drive the first spring 18 to slide along the first mounting groove, thereby disengaging from the first limit hole, and then move the first connecting plate 15 upward, thereby driving the motor 1304 to move upward. At this time, the second connecting plate 16 slides along the inner wall of the limit box 17 until the first limit rod 19 is on the side of the first limit hole above. At this time, the first spring 18 will return to its natural state, thereby driving the first limit rod 19 to move in the direction away from the first mounting groove until the first spring 18 returns to its natural state. At this time, the first limit rod 19 is located on the outside of the first limit hole, thereby fixing the second connecting plate 16 to the inside of the limit box 17, thereby fixing the motor 1304.

[0034] Working step four: then the staff can place the second installation box 801 above the conical platform 2, and then align the L-shaped plate 21 with the connecting groove, and then use the fingers to push the scraper 1005 to move in the direction close to the vibrating rod 7. At this time, the second spring 1002 is in a compressed state, and then the scraper 1005 can be placed along the top of the conical platform 2. At this time, the second spring 1002 will restore its natural shape without the resistance of the fingers, driving the rubber piston 1003 and the connecting rod 1004 to move in the direction away from the vibrating rod 7, so that it can stretch out inside the conical platform 2, which is convenient for stirring the cement mortar inside the conical platform 2, increasing the stirring area and intensity, and at the same time, it can also scrape off the concrete attached to the inside of the conical platform 2 (the second spring 1002 restores its natural state, and the scraper 1005 will conflict with the inner wall of the conical platform 2). Here, the upper and lower sides of the end of the scraper 1005 are provided with inclined surfaces, which are in contact with the The inner wall of the conical table 2 is adapted to each other. In addition, when the vibrating rod 7 moves downward, the L-shaped plate 21 will move along the connecting groove until the second limit rod 23 hits the fixed plate 20. Then the staff can press the second limit rod 23 until the second limit rod 23 drives the third spring 22 to move along the inner wall of the second mounting groove until the second limit rod 23 is located inside the second mounting groove. Then continue to press the second mounting box 801 downward until the second limit rod 23 is located on the side of the second limit hole. At this time, the third spring 22 will return to its natural state, driving the second limit rod 23 to move away from the second mounting groove until the second limit rod 23 is located outside the second limit hole, so that the L-shaped plate 21 can be fixed to the inside of the connecting groove. At this time, when the second mounting box 801 moves downward, it will drive the second bevel gear 805 to move downward until the second limit plate 1205 is located inside the third limit groove.

[0035] Working step five: Then the staff can continue to turn on the motor 1304, so that the motor 1304 drives the third worm 1202 to rotate, thereby driving the third worm wheel 1204 to rotate, thereby driving the third rotating rod 1203 to rotate, thereby driving the second limiting plate 1205 to rotate. Since the second limiting plate 1205 is slidingly connected to the third limiting groove at this time, and the second limiting plate 1205 is located inside the third limiting groove, the second limiting plate 1205 will drive the second bevel gear 805 to rotate while rotating, thereby driving the first bevel gear 804 to rotate, thereby driving the second turbine 802 to rotate, thereby driving the vibrating rod 7 to rotate, thereby driving the connecting rod 1004 and the scraper 1005 to rotate, and stirring the concrete inside the conical table 2.

[0036] Working step six: After the mixing is completed, the staff can press the second limit rod 23 to make the second limit plate 1205 inside the second mounting groove, and then lift it upward, thereby driving the vibrating rod 7 and the scraper 1005 to move upward. When the scraper 1005 moves upward, it will conflict with the inside of the conical table 2, thereby driving the scraper 1005 to move upward and driving the connecting rod 1004 to move in the direction of the vibrating rod 7 until the scraper 1005 is separated from the conical table 2 and is located above the conical table 2.

[0037] Working step seven: the staff can start the electric push rod 902, so that the electric push rod 902 drives the third connecting plate 903 to move upward, thereby driving the movable plate 4 to move upward. At this time, since the first clamping plate 607 and the second clamping plate 608 are in a clamping state on the conical platform 2, the conical platform 2 will be driven to move upward, so as to facilitate pouring the concrete inside the conical platform 2 onto the bearing plate 1. The staff uses tools such as rulers to measure the height and width of the concrete after collapse, so as to evaluate the fluidity of the concrete.
