Description

Technical Field

[0001] This utility model relates to the field of board material testing technology, and in particular to a density testing device for building engineering boards. Background Technology

[0002] Construction board is a material used in building structures, commonly used in building walls, roofs, floors, partitions, etc. It is mainly made of wood particles, fine wood chips or other fibrous materials and a suitable amount of adhesive. When testing the density of construction board, corresponding testing devices are generally used.

[0003] Currently, the density testing process for engineering slabs typically involves placing them in a container filled with water, allowing some water to overflow into an external collection device. The density is then determined by analyzing the overflowed water. However, after each use, the water in the container overflows, causing the water level to drop. When the slabs are reused, they need to be refilled. Existing testing devices generally use water pumps for this purpose, which can lead to inconsistent water levels due to varying amounts of water injected. This negatively impacts the quality of subsequent engineering slab testing.

[0004] Therefore, it is necessary to provide a device for detecting the density of slabs in building construction to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a density testing device for building engineering slabs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a building engineering slab density testing device, comprising a base, a water tank and a support frame at the top of the base, an electric hydraulic rod fixedly installed at the bottom of the water tank, the telescopic end of the electric hydraulic rod extending movably into the water tank and fixedly connected to an annular frame, an annular frame fixedly connected inside the water tank, a collection frame fixedly connected inside the annular frame, a drain pipe fixedly connected to the bottom of the collection frame, an annular scraper fixedly connected to the top of the collection frame, a rotating component and a winding and unwinding mechanism provided on the support frame, a placement frame fixedly connected to the winding and unwinding mechanism, the support frame being located on one side of the water tank, and the outer surface of the annular frame movably abutting against the collection frame.

[0007] As a further description of the above technical solution:

[0008] A sealing ring is fixedly embedded on the outer surface of the annular frame, and an inclined block is fixedly connected to the bottom of the inner wall of the collection frame. The sealing ring abuts against the annular scraper. By setting the sealing ring, the sealing between the annular frame and the collection frame can be improved, preventing some water from being discharged from the connection and affecting subsequent testing.

[0009] As a further description of the above technical solution:

[0010] A water inlet pipe is fixedly connected to one side of the water tank, and a drain pipe is fixedly connected through the water tank and extends to the outside.

[0011] As a further description of the above technical solution:

[0012] Guide grooves are provided on both sides of the inner wall of the water tank. Guide blocks are slidably connected inside the two guide grooves. The two guide blocks are fixedly connected to the outer surface of the annular frame. The two guide grooves are opened opposite each other.

[0013] As a further description of the above technical solution:

[0014] A sealing block is fixedly connected to the bottom of the inner wall of the water tank. The sealing block is movably sleeved on the outer surface of the telescopic end of the electric hydraulic rod. By setting the sealing block, water inside the water tank can be prevented from being discharged from the connection between the telescopic rod of the electric hydraulic rod and the water tank.

[0015] As a further description of the above technical solution:

[0016] The water tank is equipped with a controller on its front side, and the support frame has an annular groove on its top. The support frame is L-shaped.

[0017] As a further description of the above technical solution:

[0018] The rotating assembly includes a motor and a connecting plate. The motor is fixedly installed at the bottom of the support frame, and the connecting plate is rotatably connected to the top of the support frame through an annular groove. The bottom of the connecting plate is fixedly connected to the output end of the motor, and the winding and unwinding mechanism is fixedly installed at the top of the connecting plate.

[0019] As a further description of the above technical solution:

[0020] Two multi-stage telescopic rods are fixedly connected to the connecting plate. The telescopic ends of the two multi-stage telescopic rods are fixedly connected to the top of the placement frame. The two multi-stage telescopic rods are arranged symmetrically.

[0021] This utility model has the following beneficial effects:

[0022] 1. Compared with existing technologies, this building slab density testing device injects an appropriate amount of water into the water tank through the inlet pipe, and then activates the electric hydraulic rod to move the annular frame downwards. This allows the annular frame to be easily lowered into the water inside the tank, ensuring that the entire annular frame is submerged. This ensures that when the annular frame is subsequently moved upwards, the amount of water injected inside is uniform and the water level is consistent. This solves the problem that existing testing devices, which use water pumps to inject water, are prone to injecting too much or too little water, resulting in inconsistent water levels. This, in turn, improves the quality of building slab testing.

[0023] 2. Compared with existing technologies, this building slab density testing device, through the configuration of a base, support frame, winding and unwinding mechanism, controller, motor, connecting plate and multi-stage telescopic rod, can rotate the placement frame to the front and stably adjust its working height. This not only avoids the water tank from obstructing the up and down operation of the slab, but also improves the loading and unloading efficiency of the slab. Attached Figure Description

[0030] 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.

[0031] Reference Figure 1-4This utility model provides a density testing device for building slabs: It includes a base 1, a water tank 2 and a support frame 3 on the top of the base 1, a water inlet pipe 14 fixedly connected to one side of the water tank 2, an electric hydraulic rod 4 fixedly installed at the bottom of the water tank 2, the telescopic end of the electric hydraulic rod 4 extending movably into the water tank 2 and fixedly connected to an annular frame 5, a sealing block 17 fixedly connected to the bottom of the inner wall of the water tank 2, the sealing block 17 movably fitting on the outer surface of the telescopic end of the electric hydraulic rod 4, an annular frame 6 fixedly connected inside the water tank 2, a collection frame 7 fixedly connected inside the annular frame 6, a drain pipe 8 fixedly connected to the bottom of the collection frame 7, the drain pipe 8 fixedly penetrating the water tank 2 and extending to the outside, and the top of the collection frame 7 fixedly... A ring scraper 9 is fixedly connected to the water tank 2. A controller 18 is installed on the front of the water tank 2. A ring groove 19 is opened on the top of the support frame 3. A rotating component and a winding and unwinding mechanism 10 are installed on the support frame 3. A placement frame 11 is fixedly connected to the winding and unwinding mechanism 10. After injecting an appropriate amount of water into the water tank 2 through the water inlet pipe 14, the electric hydraulic rod 4 is activated to move the ring frame 5 downward. This allows the ring frame 5 to be easily moved down into the water inside the water tank 2, so that the entire ring frame 5 is submerged in the water. This ensures that when the ring frame 5 is subsequently moved upward, the amount of water injected inside is uniform and the water level is consistent. This solves the problem that existing testing devices, which inject water through a water pump, are prone to injecting too much or too little water, resulting in inconsistent water levels. This improves the quality of engineering plate testing.

[0032] A sealing ring 12 is fixedly embedded on the outer surface of the annular frame 5, and an inclined block 13 is fixedly connected to the bottom of the inner wall of the collection frame 7. By setting the inclined block 13, water that moves out into the collection frame 7 can be collected and discharged to prevent water from remaining in the collection frame 7 and affecting the detection quality of the engineering plate.

[0033] Guide grooves 15 are provided on both sides of the inner wall of the water tank 2. Guide blocks 16 are slidably connected inside the two guide grooves 15. The two guide blocks 16 are fixedly connected to the outer surface of the annular frame 5. By setting the guide grooves 15 and guide blocks 16, the annular frame 5 can be guided and limited, improving the stability of the annular frame 5 when it moves up and down.

[0034] The rotating assembly includes a motor 20 and a connecting plate 21. The motor 20 is fixedly installed at the bottom of the support frame 3, and the connecting plate 21 is rotatably connected to the top of the support frame 3 through an annular groove 19. The bottom of the connecting plate 21 is fixedly connected to the output end of the motor 20. The winding and unwinding mechanism 10 is fixedly installed on the top of the connecting plate 21. Through the arrangement of the base 1, support frame 3, winding and unwinding mechanism 10, controller 18, motor 20, connecting plate 21 and multi-stage telescopic rod 22, the placement frame can be rotated to the front and its working height can be stably adjusted. This not only avoids the water tank 2 from obstructing the up and down operation of the engineering board, but also improves the loading and unloading efficiency of the engineering board.

[0035] Two multi-stage telescopic rods 22 are fixedly connected to the connecting plate 21. The telescopic ends of the two multi-stage telescopic rods 22 are fixedly connected to the top of the placement frame 11. The multi-stage telescopic rods 22 can guide and limit the vertical movement of the placement frame 11, thereby improving its vertical movement stability.

[0036] Working principle: When in use, first add clean water into the water tank 2 through the water inlet pipe 14 until the water level reaches half the height of the collection frame 7. Then, place a measuring cup below the end of the collection pipe away from the collection frame 7, start the electric hydraulic rod 4 to retract its telescopic end, and drive the ring frame 5 to move down until the bottom of the ring frame 5 abuts against the top of the sealing block 17 and the top is lower than the collection frame 7, so that the clean water added to the water tank 2 automatically flows into the ring frame 5. Start the electric hydraulic rod 4 again to extend its telescopic end to reset, and drive the ring frame 5 filled with water to move up and reset. Then, start the motor 20 to drive the connecting plate 21, the winding and unwinding mechanism 10 and the placement frame 11 to rotate 90 degrees synchronously. The placement frame 11 can be rotated to the front. After starting the winding and unwinding mechanism 10 to extend the telescopic ends of the multi-stage telescopic rod 22 synchronously, the placement frame 11 can be adjusted to a suitable height to facilitate the placement of the engineering board.

[0037] When the engineering board is placed on the placement rack 11, and with the cooperation of the motor 20 and the winding mechanism 10, the placement rack 11 is reset above the annular frame 5. Then, the winding mechanism 10 is started again, which can smoothly move the placement rack 11 and the engineering board into the annular frame 5, causing the water inside the annular frame 5 to overflow. Under the guidance and interception of the annular scraper 9, the overflowing water falls into the collection frame 7. Then, under the guidance of the inclined block 13, the water inside the collection frame 7 is collected and discharged into the pre-placed measuring cup through the drain pipe 8, which is convenient for subsequent engineering board density measurement and testing.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
