Description

Technical Field

[0001] The invention relates to the technical field of compressive strength detection devices, in particular to a compressive strength test device for building waste recycled materials. Background Art

[0002] Domestic research on construction waste mainly focuses on the preparation and mix ratio of construction waste recycled materials and their application in highways, loess foundations, and soft foundation treatment. It focuses more on the research and development of equipment for separating construction waste, research on material mix ratios, particle size, and other aspects, as well as construction technology and quality control of the construction process. Construction waste should be processed and sorted into brick aggregates and concrete aggregates. Brick aggregates can be used for roadbed filling, and concrete aggregates can be used for road base and subbase. Recycled aggregates composed of concrete blocks have very good properties compared with natural aggregates, and can meet the standard requirements of most roads for concrete aggregates. Such recycled aggregates can be added to flexible road base materials. As long as the recycled aggregates produced can meet the quality standards, they can be used as a base or subbase material. The performance of recycled aggregates is completely comparable to that of natural aggregates as base materials; in hot-mix asphalt mixtures, because recycled aggregates can adhere to the surface of hot asphalt liquid, hot asphalt liquid can avoid precipitation. Recycled aggregates are more suitable for hot-mix asphalt concrete road construction projects. Hot-mix asphalt concrete is used in most municipal roads in my country.

[0003] Concrete slabs made from recycled materials from construction waste usually need to be tested for compressive strength before use. The conventional testing method is to place the slab on a testing table and apply pressure to test its compressive strength. However, for recycled materials from construction waste, mixing in different proportions may produce different effects. Therefore, repeated tests are required for different ratios. In actual operation, the slabs need to be prepared in advance and then placed on the testing table. After the test is completed, the slabs and their debris need to be taken out, which is inefficient.

[0006] Furthermore, two slide rails are fixed to the bottom of one side of the opening of the detection platform, a slide frame is fixed to the bottom of the collection frame, and the slide frame can be slidably buckled on the slide rails, and the top of the collection frame is flush with the bottom surface of the detection platform.

[0007] Furthermore, the prefabricated component also includes an insertion rod, two insertion rods are fixed at the outer end of the collection frame, and the insertion rods are slidably inserted into the bottom of the placement frame. Slide grooves are opened on the bottom surfaces of both sides of the placement frame, and the bottoms of both ends of the first clamp slide along the slide grooves.

[0008] Furthermore, slides are fixed at both ends of the second clamping plate, and the slides slide along the outer surface of the first clamping plate. The second clamping plate is composed of two connecting plates and a two-way telescopic plate. Bolts are threadedly inserted on the surface of the slide and at the connection between the connecting plate and the extended end of the two-way telescopic plate.

[0009] Furthermore, plug boards are slidably plugged into the tops of both sides of the placement frame, and contact blocks are fixed on the tops of the plug boards. Springs are fixed on both sides of the bottom of the contact blocks, and the other ends of the springs are fixedly connected to the placement frame.

[0010] Furthermore, a first connecting rod is symmetrically connected to the bottom surface of the contact block via a rotating shaft, and the other end of the first connecting rod is rotationally connected to the first clamping plate via a rotating shaft. A second connecting rod is rotationally connected to the inner surface of the first clamping plate via a rotating shaft, and the other end of the second connecting rod is rotationally connected to the two side extended ends of the second clamping plate.

[0011] Furthermore, the pressure assembly also includes a cylinder, a cylinder is fixed at the bottom of the movable seat, the extended end of the cylinder is fixedly connected to the pressure plate, connecting frames are fixed on both sides of the top of the pressure plate, and a second electric push rod is fixed at the position of the connecting frame corresponding to the contact block.

[0012] Furthermore, a third screw rod is rotatably mounted on both sides of the detection platform through a bearing seat, a base is threadedly sleeved on the surface of the third screw rod, and the bottom of the vertical frame is fixed on the base.

[0013] Furthermore, the pushing assembly also includes a first screw rod, the first screw rod is rotatably installed inside the slide groove through a bearing, and the slide plate is threadedly sleeved on the surface of the first screw rod, and the first screw rod, the second screw rod and the third screw rod are all driven by a motor.

[0014] Furthermore, a first electric push rod is fixed on the top of the slide plate, and a socket is provided at the bottom of the front end of the inserting strip, and the extended end of the first electric push rod can pass through the gap between the movable groove and the slot and be inserted into the socket.

[0015] Beneficial effects of the present invention: 1. In the present invention, the base drives the vertical frame and the pressure plate to move forward and backward through the rotation of the third screw rod, and the position of the pressure plate is adjusted so that the position of the connecting frame corresponds to the contact block. At this time, the center line of the pressure plate corresponds to the center line of the concrete slab inside the prefabricated component. When the cylinder drives the pressure plate to descend, the connecting frame descends at the same time. Because the connecting frame is L-shaped, the contact block is squeezed by the second electric push rod according to the distance between the contact block and the connecting frame before the pressure plate contacts the concrete slab. Because the locking bolt is unlocked in advance, the first clamping plate and the second clamping plate are not fixed to each other. After the contact block is squeezed, the first connecting rod pushes the first clamping plate to both sides to release the clamping limit on the front and rear sides of the concrete slab. At the same time, the bidirectional telescopic plate of the second clamping plate is extended, and as the first clamping plate moves, the second connecting rod drives the second clamping plate to move outward, thereby releasing the clamping effect on the left and right sides of the concrete slab, thereby avoiding interference with the detection of the compressive strength of the concrete slab.

[0016] 2. The present invention uses a two-way telescopic plate and a vertical plate of the second clamping plate to fix the connection with bolts. According to the size of the concrete slab to be prepared, a two-way telescopic plate of relative length is selected, that is, the extended ends at both ends of the two-way telescopic plate are completely retracted to ensure that the four sides of the concrete slab are flat. The two-way telescopic plate only works when the limit is released. By sliding the first clamping plate along the slide groove and then fixing the slide on the outer surface of the first clamping plate with bolts, the first clamping plate and the second clamping plate can form a frame for preparing the concrete slab, and can also limit the concrete slab when it is sent to the inspection table to avoid the displacement of the concrete slab.

[0017] 3. The present invention can push the collecting frame toward one side of the testing platform by sliding the sliding frame at the bottom along the sliding rail. When the collecting frame is aligned with the testing platform, the placing frame at the upper end is pushed. The concrete slab is sent into the testing platform under the action of the placing frame, and the inserting strips on both sides of the placing frame are inserted into the slots. The extended end of the first electric push rod at the top of the slide plate is inserted into the jack of the insert cylinder. Then the first screw rod drives the slide plate to slide along the moving groove. The placing frame and the concrete slab can be assisted to enter the testing platform by the movement of the slide plate to avoid the inconvenience of manual handling. After the test is completed, the placing frame is sent out by the drive of the first screw rod. When the compression test is performed, the concrete slab may be broken. Because the first splint, the second splint and the wrapped placing frame, the broken slag stays in the wrapped frame and can be pushed into the collecting frame to avoid residue on the testing platform and save time for cleaning the testing platform.

[0018] 4. Compared with the prior art, the present invention has a concrete slab located inside a prefabricated component for preparation and testing, which can save time for transportation and fixation. At the same time, it can be used for testing slabs of different sizes. The slab can be conveniently sent into the testing table by pushing the component and maintained in a corresponding position with the pressing plate, which is convenient for subsequent delivery and cleaning of the testing table and improves the test efficiency.

After the concrete slab 5 is formed, it is sent to the detection position through the sliding cooperation of the prefabricated component 2 and the detection platform 1. The surface of the concrete slab 5 is squeezed by the pressure component 3, and the compressive strength of the concrete slab 5 is detected according to the technical method in CN117433912A.

When the collecting frame 21 is aligned with the testing table 1, the placing frame 24 at the upper end continues to be pushed. The concrete slab 5 is sent into the testing table 1 under the action of the placing frame 24, and the inserting strips 27 on both sides of the placing frame 24 are inserted into the slots 12, and the extended end of the first electric push rod 44 at the top of the slide plate 43 is inserted into the insert hole 28 of the insert cylinder. Then the first screw rod 42 drives the slide plate 43 to slide along the moving groove 41. The movement of the slide plate 43 can assist the placing frame 24 and the concrete slab 5 to enter the testing table 1, avoiding the inconvenience of manual handling. After the inspection is completed, the placing frame 24 is also driven by the first screw rod 42 to send it out. During the compression test, the concrete slab 5 may be broken. Because of the action of the first splint 25, the second splint 26 and the wrapped placing frame 24, the debris stays inside the wrapped frame and can be pushed into the collecting frame 21, avoiding residue on the testing table 1 and saving time for cleaning the testing table 1.

[0024] In this embodiment, the bottom surfaces of both sides of the placement frame 24 are provided with slide grooves 29, the bottoms of both ends of the first clamping plate 25 slide along the slide grooves 29, the two ends of the second clamping plate 26 are fixed with slides 213, and the slide 213 slides along the outer surface of the first clamping plate 25, the second clamping plate 26 is composed of two connecting plates and a two-way telescopic plate, the surface of the slide 213 and the connection between the connecting plate and the extended end of the two-way telescopic plate are all threaded with bolts, the top of both sides of the placement frame 24 is slidably inserted with plug plates 215, and the top of the plug plates 215 is fixed with contact blocks 210, the bottom sides of the contact block 210 are fixed with springs 216, and the other end of the spring 216 is fixedly connected to the placement frame 24, and the bottom surface of the contact block 210 is connected by a rotating shaft A first connecting rod 211 is symmetrically rotatably connected, and the other end of the first connecting rod 211 is rotatably connected to the first clamping plate 25 through a rotating shaft. A second connecting rod 212 is rotatably connected to the inner surface of the first clamping plate 25 through a rotating shaft, and the other end of the second connecting rod 212 is rotatably connected to the extended ends on both sides of the second clamping plate 26. The pressure component 3 also includes a cylinder 34, a cylinder 34 is fixed to the bottom of the movable seat 33, and the extended end of the cylinder 34 is fixedly connected to the pressing plate 35. Connecting frames 36 are fixed to both sides of the top of the pressing plate 35, and a second electric push rod 37 is fixed to the position of the connecting frame 36 corresponding to the contact block 210. A third screw rod 38 is rotatably installed on both sides of the detection platform 1 through a bearing seat, and a base 39 is threadedly sleeved on the surface of the third screw rod 38 , and the bottom of the vertical frame 31 is fixed on the base 39. Through the rotation of the third screw rod 38, the base 39 drives the vertical frame 31 and the pressing plate 35 to move forward and backward, and adjusts the position of the pressing plate 35 so that the position of the connecting frame 36 corresponds to the contact block 210. At this time, the center line of the pressing plate 35 corresponds to the center line of the concrete slab 5 inside the prefabricated component 2. When the cylinder 34 drives the pressing plate 35 to descend, the connecting frame 36 descends at the same time. Because the connecting frame 36 is L-shaped, according to the distance between the contact block 210 and the connecting frame 36 before the pressing plate 35 contacts the concrete slab 5, the contact block 210 is squeezed by the second electric push rod 37. Because the locking bolt 214 is unlocked in advance, the first clamping plate 25 and the second clamping plate 26 are not fixed to each other. After the contact block 210 is squeezed, the first connecting rod 211 pushes the first clamping plate 25 to both sides to release the clamping limit on the front and rear sides of the concrete slab 5. At the same time, the two-way telescopic plate of the second clamping plate 26 is extended, and as the first clamping plate 25 moves, the second connecting rod 212 drives the second clamping plate 26 to move outward to release the clamping effect on the left and right sides of the concrete slab 5. The movement range will not be too large, and it is just a simple contact to squeeze the four sides of the concrete to avoid interference with the detection of the compressive strength of the concrete slab 5. The two-way telescopic plate of the second clamping plate 26 and the vertical plate are fixedly connected by bolts. According to the size of the concrete slab 5 to be prepared, a two-way telescopic plate of relative length is selected, that is, the extended ends at both ends of the two-way telescopic plate are fully retracted to ensure that the four sides of the concrete slab 5 are flat. The two-way telescopic plate only works when the limit is released.By sliding the first clamping plate 25 along the slide groove 29 and then fixing the slide 213 on the outer surface of the first clamping plate 25 by bolts, the first clamping plate 25 and the second clamping plate 26 can form a frame for preparing the concrete slab 5, and can also limit the position of the concrete slab 5 when it is sent to the inspection table 1 to prevent the concrete slab 5 from deflecting.

[0025] When the device is used, a concrete slab 5 is prepared according to different proportions of recycled materials from construction waste inside the prefabricated component 2, the size of the concrete slab 5 can be adjusted, the prepared concrete slab 5 is placed on the slide rail 11 together with the prefabricated component 2, and the slide frame 22 at the bottom of the collection frame 21 slides along the slide rail 11, and can be pushed to one side of the detection table 1. When the collection frame 21 is aligned with the detection table 1, the placement frame 24 at the upper end is continued to be pushed, and the concrete slab 5 is sent into the detection table 1 under the action of the placement frame 24, and the insertion strips 27 on both sides of the placement frame 24 are inserted into the slot 12, and the extended end of the first electric push rod 44 at the top of the slide plate 43 is inserted into the socket 28 of the insert tube, and then the first screw rod 42 drives the slide plate 43 to slide along the moving groove 41, and the slide plate 43 can be passed through the slide plate 43 The mobile auxiliary placement frame 24 and the concrete slab 5 enter the interior of the testing table 1 to avoid the inconvenience of manual handling. After the test is completed, the placement frame 24 is sent out by the driving of the first screw rod 42. During the compression test, the concrete slab 5 may be broken. Because of the action of the first clamping plate 25, the second clamping plate 26 and the wrapped placement frame 24, the broken slag stays inside the wrapped frame and can be pushed into the collection frame 21 to avoid residue on the testing table 1 and save time for cleaning the testing table 1. Through the rotation of the third screw rod 38, the base 39 drives the vertical frame 31 and the pressing plate 35 to move back and forth, and adjusts the position of the pressing plate 35 so that the position of the connecting frame 36 corresponds to the contact block 210. At this time, the center line of the pressing plate 35 is aligned with the concrete slab 5 inside the prefabricated component 2. Corresponding to the center line of the concrete slab 5, when the cylinder 34 drives the pressing plate 35 to descend, the connecting frame 36 also descends. Because the connecting frame 36 is L-shaped, according to the distance between the contact block 210 and the connecting frame 36 before the pressing plate 35 contacts the concrete slab 5, the contact block 210 is squeezed by the second electric push rod 37. Because the locking bolt 214 is unlocked in advance, the first clamping plate 25 and the second clamping plate 26 are not fixed to each other. After the contact block 210 is squeezed, the first connecting rod 211 pushes the first clamping plate 25 to both sides to release the clamping limit on the front and rear sides of the concrete slab 5. At the same time, the bidirectional telescopic plate of the second clamping plate 26 is extended, and as the first clamping plate 25 moves, the second connecting rod 212 drives the second clamping plate 26 to move outward to release the clamping effect on the left and right sides of the concrete slab 5. , the moving range will not be too large, it is just a simple contact squeezing effect on the four sides of the concrete, avoiding interference with the detection of the compressive strength of the concrete slab 5, the bidirectional telescopic plate and the vertical plate of the second clamping plate 26 are bolted and fixedly connected, according to the size of the concrete slab 5 to be prepared, a bidirectional telescopic plate of relative length is selected, that is, the two ends of the bidirectional telescopic plate are in a fully retracted state to ensure that the four sides of the concrete slab 5 are flat, and the bidirectional telescopic plate only plays a role when the limit is released, by sliding the first clamping plate 25 along the slide groove 29 and then fixing the slide 213 on the outer surface of the first clamping plate 25 by bolts, the first clamping plate 25 and the second clamping plate 26 can form a frame for preparing the concrete slab 5, and can also limit the concrete slab 5 when it is sent to the testing table 1,To prevent the concrete slab 5 from deflecting, the surface of the concrete slab 5 is pressed by the pressure component 3 to detect the compressive strength of the concrete slab 5.
