Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for detecting the density of building slabs. Background Technology

[0002] Density is an important indicator for measuring the quality of building materials; by testing the density, we can determine the uniformity and internal structure of the material and ensure that it meets the design requirements.

[0003] The density testing methods for building slabs include the water displacement method: the building slab is completely immersed in a known volume of water, the volume of water level rise is measured, the volume of the slab is determined by the amount of water displaced, and then the density is calculated.

[0004] Chinese Patent Publication No. CN222189061 U discloses a density testing device for building slabs, including an outer water storage frame, an inner overflow frame fitted to the inner bottom surface of the outer water storage frame, and several equally spaced overflow holes around the inner overflow frame. A bracket extending above the inner overflow frame is fitted to the top of the outer water storage frame, and a winch is mounted on the end of the bracket surface. A cable passing through the end of the bracket is wound on the winch, and a building slab fixing component is attached to the bottom of the cable. The outer periphery of the outer water storage frame has graduation lines. This invention accurately measures the volume of the building slab by measuring the volume of water discharged when the building slab is immersed in water, without needing to remove the building slab. This effectively avoids the adverse interference of water droplets adhering to the building slab after removal from the water on the volume measurement, thus improving the accuracy of building slab density testing and being relatively simple to use.

[0005] The aforementioned panel fixing component for fixing the building panel is located inside the inner overflow frame and cannot be moved out of the inner overflow frame. As a result, the inner overflow frame will hinder the process of fixing the building panel to the panel fixing component. Utility Model Content

[0006] The main objective of this invention is to provide a density testing device for building slabs, which can effectively solve the problem that the water-containing device used for density testing of building slabs hinders the process of fixing the building slabs in the components used to fix the building slabs.

[0012] Preferably, the hoisting assembly includes an electric telescopic rod, which is fixedly connected to the upper right side of the horizontal portion of the cantilever plate. The lower end of the piston rod at the output end of the electric telescopic rod passes through the upper end of the horizontal portion of the cantilever plate and extends to the lower side of the horizontal portion of the cantilever plate. The lower end of the piston rod at the output end of the electric telescopic rod is fixedly connected to a mounting housing, and a clamping assembly is provided on the inner surface of the mounting housing.

[0013] Preferably, the clamping assembly includes a second motor, which is fixedly connected to the middle of the front end of the mounting housing.

[0014] Preferably, the limiting component includes a limiting plate, which is fixedly connected to the middle of the rear end of the water tank, and a limiting groove is formed at the upper end of the horizontal portion of the limiting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The hoisting component of this utility model facilitates the process of placing and removing the building slab from the water during density testing; the rotating component allows the hoisting component to be moved from above the water tank, ensuring that the water tank does not obstruct the process of fixing the building slab in the clamping component, thus facilitating the density testing process of the building slab.

[0017] 2. The limiting plate set in this utility model limits the downward movement of the installation shell, which ensures that the depth and volume of the clamping component entering the water are the same each time, thereby ensuring that the volume of water displaced by the clamping component after each entry into the water is the same. This prevents the different volumes of water displaced by the clamping component after each entry into the water from affecting the accuracy of the data on the density of the building engineering board.

[0028] In the specific implementation, the pumping component 3 is turned on to pump the external water source to the water tank 2. The scale line in the water tank 2 is observed. After a certain amount of water is injected into the water tank 2, the volume of water in the water tank 2 at this time is recorded as a, which is temporarily set as the initial reference data.

[0029] Start the hoisting assembly 6 to move into the water tank 2.

[0030] Start the hoisting assembly 6 to move out of the water, start the rotating assembly 5 to move the hoisting assembly 6 out of the water tank 2, use the hoisting assembly 6 to fix the building engineering slab for density testing, and then start the rotating assembly 5 to move both the hoisting assembly 6 and the building engineering slab to the position above the water tank 2.

[0031] Observe whether the volume of water in water tank 2 is the same as the initial data a. If it is different, add water to water tank 2 through water pumping component 3 or release water from water tank 2 through water outlet component 4 to adjust the volume of water in water tank 2 to the initial data a.

[0032] Then, start the hoisting assembly 6 to move the building slab into the water tank 2. After it moves to the position where it is blocked by the two limiting assemblies 7, observe the volume of water in the water tank 2 after the water level rises and record the data at this time, tentatively named c. The volume of water displaced after the building slab enters the water is cba.

Figure 2The water pumping assembly 3 includes a water pump 31, which is fixedly connected to the upper right side of the base plate 1.

An inlet pipe 33 is fixedly connected to the output end of the water pump 31. The water outlet assembly 4 includes an outlet pipe 41, which is fixedly connected to and passes through the lower front right side of the water tank 2. A ball valve 42 is fixedly connected to the right end of the outlet pipe 41. A round pipe 43 is fixedly connected to the right end of the ball valve 42.

[0035] Further reading Figure 3 The rotating assembly 5 includes a support column 51, which is fixedly connected to the middle of the left side of the upper end of the base plate 1. A cylinder 55 is rotatably connected to the upper end of the support column 51. A driven gear 56 is fixedly connected to the outer surface of the cylinder 55. A cantilever plate 57 is fixedly connected to the upper end of the cylinder 55. A motor 52 is fixedly connected to the upper rear end of the support column 51. A rotating shaft 53 is fixedly connected to the output end of the motor 52 through a coupling. A drive gear 54 is fixedly connected to the outer surface of the rotating shaft 53. The drive gear 54 meshes with the driven gear 56.

[0036] Further reading Figure 4 The hoisting assembly 6 includes an electric telescopic rod 61, which is fixedly connected to the upper right side of the horizontal part of the cantilever plate 57. The lower end of the piston rod at the output end of the electric telescopic rod 61 passes through the upper end of the horizontal part of the cantilever plate 57 and extends to the lower side of the horizontal part of the cantilever plate 57. The lower end of the piston rod at the output end of the electric telescopic rod 61 is fixedly connected to a mounting housing 62, and a clamping assembly 63 is provided on the inner surface of the mounting housing 62.

[0037] Further reading Figure 5 The clamping assembly 63 includes a second motor 631, which is fixedly connected to the middle of the front end of the mounting housing 62. The output end of the second motor 631 is fixedly connected to a bidirectional integrated threaded rod 632 via a coupling. The rear end of the bidirectional integrated threaded rod 632 passes through the front end of the mounting housing 62 and extends into the mounting housing 62. The front and rear sides of the outer surface of the bidirectional integrated threaded rod 632 are threaded with sliding rods 633. Both sliding rods 633 are slidably connected to the upper side of the inner surface of the mounting housing 62. The lower part of the opposite end of the two sliding rods 633 is fixedly connected to a clamping plate 634. The limiting assembly 7 includes a limiting plate 71, which is fixedly connected to the middle of the rear end of the water tank 2. A limiting groove 72 is opened at the upper end of the horizontal part of the limiting plate 71.

[0038] The aforementioned bidirectional integral threaded rod 632 has threaded grooves on the front and rear sides of its outer surface in opposite directions.

[0039] In the specific implementation, the inlet pipe 33 is connected to the external water pipe, the external water pipe is placed into the external water source, the water pump 31 is turned on to pump the external water source to the water tank 2, the scale line in the water tank 2 is observed, a certain amount of water is injected into the water tank 2, and the volume of water in the water tank 2 at this time is recorded as a, which is temporarily set as the initial water level reference data.

[0040] The electric telescopic rod 61 is activated to extend the piston rod, which drives the mounting housing 62 and the clamping assembly 63 to move into the water tank 2. After moving to the position where the mounting housing 62 is respectively inserted into the two limiting grooves 72 and blocked by the two limiting plates 71, the electric telescopic rod 61 is closed.

[0041] At this time, both clamping plates 634 are submerged in water, and parts of the two sliding rods 633 are submerged in water. Observe the scale line in the water tank 2 at this time, record the water level data at this time, calculate the difference between the water volume data after the water level rises after the part of the hoisting component 6 enters the water and a, tentatively set as b, to be used later.

[0042] When the electric telescopic rod 61 is activated and the piston rod is retracted, the two clamping plates 634 and the two sliding rods 633 are moved out of the water. After the two clamping plates 634 are moved to a position above the two limiting plates 71, the motor 52 is activated to drive the rotating shaft 53 to rotate, which in turn drives the drive gear 54 to rotate, which in turn drives the driven gear 56 to rotate, which in turn drives the cylinder 55 to rotate, which in turn drives the cantilever plate 57 to rotate, which in turn drives the hoisting assembly 6 to rotate, so that the hoisting assembly 6 moves out of the position above the water tank 2. In this way, the water tank 2 will not obstruct the process of fixing the building slab in the clamping assembly 63, thus facilitating the density detection process of the building slab.

[0043] After completing the above operations, start motor 631 to drive bidirectional integrated threaded rod 632 to rotate forward, thereby driving the two sliding rods 633 to move closer to each other until the building slab is clamped and fixed securely.

[0044] Then, the motor 52 is turned on to drive the rotating shaft 53 to rotate, causing the cantilever plate 57 to rotate, thereby moving the hoisting assembly 6 and the building slab back to the position above the water tank 2;

[0045] Observe whether the volume of water in water tank 2 is the same as the initial data. If it is different, inject water into water tank 2 by turning on water pump 31 or drain water from water tank 2 by opening ball valve 42, and adjust the volume of water in water tank 2 to the initial data a.

[0046] Then, the electric telescopic rod 61 is activated to extend the piston rod, which drives the building engineering panel to move into the water tank 2. After it moves to the position where the mounting housing 62 is respectively inserted into the two limiting grooves 72 and blocked by the two limiting plates 71, the electric telescopic rod 61 is closed.

[0047] The volume and depth of the part of the clamping component 63 entering the water are the same as before. After the part of the clamping component 63 enters the water, the volume of water displaced is the same as before. This ensures that the data of b remains unchanged after the clamping component 63 enters the water twice, so that this data will not affect the accuracy of the data for detecting the density of the building engineering board.

[0048] After completing the above operations, observe the volume of water in tank 2 after the water level rises, and record the volume after the water level rises, tentatively named c. The volume of water displaced after the building slab enters the water surface alone is cba.

[0049] It should be noted that the specific installation methods, circuit connection methods, and control methods of the motor 52, electric telescopic rod 61, and motor 631 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0050] The working principle of this utility model is as follows:

[0051] Turn on the water pump 31 to draw out the external water source and deliver a certain amount of water into the water tank 2. Record the volume of water in the water tank 2 at this time, tentatively named a.

[0052] Activate the electric telescopic rod 61 to extend the piston rod, which drives the clamping assembly 63 to move into the water tank 2 until the mounting housing 62 is respectively inserted into the two limiting grooves 72 and blocked by the two limiting plates 71.

[0053] Observe the scale line in water tank 2 at this time, record the water level data at this time, calculate the difference between the water level data at this time and a, and tentatively set it as b, for later use;

[0054] The electric telescopic rod 61 is activated to retract the piston rod, which moves the clamping assembly 63 out of the water. The motor 52 is activated to rotate the shaft 53, which causes the cantilever plate 57 to rotate, thus moving the hoisting assembly 6 out from above the water tank 2. After the building slab is clamped and fixed in place by the clamping assembly 63, the motor 52 is activated to rotate the shaft 53, which causes the cantilever plate 57 to rotate, thus moving the hoisting assembly 6 back to the position above the water tank 2.

[0055] Ensure that the water level in water tank 2 is the same as a. Activate the electric telescopic rod 61 to extend the piston rod, driving the building slab into water tank 2. After moving to the position where the mounting shell 62 is respectively inserted into the two limiting grooves 72 and blocked by the two limiting plates 71, record the volume after the water level rises, tentatively named c. The volume of water displaced after the building slab enters the water surface alone is cba.
