Description

Technical Field

[0001] The invention belongs to the technical field of strength detection of building material boards, and in particular relates to a strength detection device and a detection method for inorganic material building material boards. Background Art

[0002] In the production process of inorganic building material boards, the strength needs to be tested, and impact strength is also one of the strengths that need to be tested for the boards.

[0003] Impact strength testing is a test method to measure the toughness or resistance to fracture of materials under high-speed impact. It is widely used in quality control and performance evaluation of various materials.

[0004] There are two detection methods:

[0005] Pendulum impact method: including the Charpy method and the Izod method. These two methods evaluate the impact strength of a material by measuring the energy absorbed by the material when it is impacted by a pendulum.

[0006] Drop hammer impact method: mainly used for impact performance testing of large components or structural parts, and its impact resistance is evaluated by measuring the response of the material under drop hammer impact.

[0007] The existing drop hammer impact method uses a motor to drive the impact hammer to rise and then fall to perform impact detection. Different impact detections are achieved by changing the height. The impact weight of the impact hammer is changed by adding counterweight blocks to perform different impact detections. When the inventor was performing the drop hammer impact method test, he found that if it was necessary to increase or decrease the counterweight blocks, it was necessary to manually take a certain weight of counterweight blocks to increase or decrease. This method makes the detection process very troublesome, and the detection personnel need to have a certain strength to better replace them, which also affects the efficiency of the impact detection.

[0008] Therefore, the existing structure and defects are studied and improved, and an inorganic material building material board strength detection device and detection method are provided, in order to achieve a more practical purpose. Summary of the invention

[0018] Preferably, there are four mounting holes, and the mounting holes are symmetrically distributed on the counterweight.

[0019] A method for testing the strength of an inorganic material building material board, using the inorganic material building material board strength testing device, comprises the following steps:

[0020] S1 places the plate on the base, controls the extrusion plate to fix the plate, and then controls the impact plate to rise to the set height and then move downward, driving the impact hammer to impact the plate;

[0021] S2 then controls the impact plate to rise, so that the mounting rod moves upward and is inserted into the corresponding limit holes in sequence, and then controls the support rods at both ends of the bottom counterweight to contract, so that the bottom counterweight automatically falls onto the impact plate. When the counterweight is completely placed on the impact plate, the impact plate is controlled to move to the set position, and then falls again to impact the plate. In this way, the number of counterweights is increased in sequence, the impact force of the impact hammer during collision is changed, and the impact effect is recorded in sequence.

[0022] S3 When the number of counterweights needs to be reduced, it is only necessary to control the impact plate to rise to the set height, and control the conveying ring to rotate, so that the support blocks move to the two ends of the counterweights on the upper end of the impact plate, and then control the support rod to extend so that the support rod engages with the support groove, and then control the conveying ring to rotate, so that the number of counterweights can be reduced. In this way, the number of counterweights can be reduced sequentially.

[0023] Compared with the prior art, the present invention has the following technical effects:

[0024] The design of the conveying ring, support block, support rod, counterweight block and support groove can realize the automatic increase and reduction of the counterweight block. This design can solve the problem of manual replacement of the counterweight block when the impact strength of the original plate is realized, which effectively improves the efficiency of the impact test and makes the operation simpler.

[0025] The design of the pressing and telescopic mechanism, pressing gear and pressing groove can utilize the rotation of the conveying ring. When the counterweight blocks are separated, it is only necessary to control the conveying ring to drive the bottom counterweight block to move to the side of the pressing gear. The pressing gear presses the pressing and telescopic mechanism. After pressing, it can automatically drive the support rod to contract, so that the support rod is separated from the support groove. At this time, the fixation of the counterweight block can be released, and the counterweight block automatically falls onto the impact plate, realizing the automatic increase of the counterweight block. When the counterweight block is recovered, it drives the conveying ring to rotate in the opposite direction. At this time, the pressing and telescopic mechanism moves to the pressing gear again, which can drive the support rod to automatically extend. This design method realizes the automatic extension and retraction of the support rod, and can match the increase and decrease of the counterweight block.

[0026] The design of the push rod, baffle, connecting piece and synchronization rod can cooperate with the extension and retraction of the support rod. After the support rod is extended, the push rod can be squeezed and contracted, and the positioning lock tongue can be driven to contract through the connecting piece. At this time, the counterweight block is fixedly installed on the support block through the support rod, and when the counterweight block needs to be separated from the mounting rod, the positioning lock tongue can be driven to contract by the extension of the support rod, so as to release the fixation between the mounting rod and the counterweight block, and then the counterweight block can be driven to separate through the conveying ring. After the support rod is contracted, the elasticity of the reset spring can drive the positioning lock tongue to extend. In this way, when the counterweight block completely falls on the impact plate, the elasticity of the reset spring can drive the positioning lock tongue to be inserted into the mounting hole, thereby realizing the connection and fixation between the counterweight block and the mounting rod, and ensuring the overall stability.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] Example 1, please refer to Figure 1 , Figure 2, a strength detection device for inorganic material building material board, comprising a base 1 and an impact hammer 43, wherein an impact plate 4 that can move up and down is provided above the base 1, and the impact hammer 43 is fixedly installed at the bottom of the impact plate 4, and a plurality of fixedly connected mounting rods 42 are provided at the upper end of the impact plate 4, and a plurality of symmetrically distributed and synchronously reversely rotating conveying rings 3 are provided above the impact plate 4, and a plurality of evenly distributed supporting blocks 33 are provided on the conveying rings 3, and a retractable supporting rod 35 is provided on the supporting blocks 33, and a plurality of evenly distributed counterweights 2 are provided above the impact plate 4, and both ends of the counterweights 2 are provided with supporting grooves 22 corresponding to the supporting rods 35, and the counterweights 2 are arranged above the impact plate 4 in a manner that the supporting grooves 22 are fixed by the supporting rods 35, and the counterweights 2 are also provided with a through-type limiting hole 21 corresponding to the mounting rod 42, and a plurality of extrusion plates 14 that can slide back and forth and are used for extruding and fixing building material boards are provided on the base 1, and an impact hole 12 corresponding to the impact hammer 43 is provided on the base 1.

[0042] The design of the conveying ring 3, support block 33, support rod 35, counterweight block 2 and support groove 22 can realize the automated increase and reduction of the counterweight block 2. Such a design can solve the problem of manually replacing the counterweight block 2 when the impact strength of the original plate is realized, effectively improving the efficiency of the impact test and making the operation simpler.

[0043] See also Figure 2 , Figure 3 and Figure 4 In this embodiment, a plurality of uniformly distributed pressing grooves 34 are provided on the inner side wall of the conveying ring strip 3, the support rod 35 is aligned with the corresponding pressing grooves 34, and a pressing telescopic mechanism 362 is provided in each of the support blocks 33. The telescopic end of the pressing telescopic mechanism 362 is fixedly connected to the support rod 35, and the pressing end of the pressing telescopic mechanism 362 is provided with a fixedly connected pressing plate 263, and the pressing plate 263 is slidably connected in the corresponding pressing groove 34. A rotatable pressing gear 36 for pressing by the pressing plate 263 is provided inside one end of the conveying ring strip 3, and the pressing gear 36 is meshed with the pressing groove 34. The pressing telescopic mechanism 362 adopts the pressing mechanism in the existing field of press-type cylindrical pens.

[0044] The design of the pressing and telescopic mechanism 362, the pressing gear 36 and the pressing groove 34 can utilize the rotation of the conveying ring 3. When the counterweight block 2 is separated, it is only necessary to control the conveying ring 3 to drive the bottom counterweight block 2 to move to the side of the pressing gear 36. The pressing gear 36 presses the pressing and telescopic mechanism 362. After pressing, it can automatically drive the support rod 35 to contract, so that the support rod 35 is separated from the support groove 22. At this time, the fixation of the counterweight block 2 can be released, and the counterweight block 2 automatically falls onto the impact plate 4, realizing the automatic increase of the counterweight block 2. When the counterweight block 2 is recovered, it drives the conveying ring 3 to rotate in the opposite direction. At this time, the pressing and telescopic mechanism 362 moves to the pressing gear 36 again, which can drive the support rod 35 to automatically extend. This design method realizes the automatic extension and retraction of the support rod 35, and can match the increase and decrease of the counterweight block 2.

[0045] See also Figure 4 In this embodiment, a first positioning groove 214 is provided on the side wall of the limiting hole 21, a retractable positioning lock tongue 211 is provided in the first positioning groove 214, and a plurality of evenly distributed mounting holes that are fixedly engaged with the positioning lock tongue 211 are provided on the mounting rod 42.

[0046] The addition of the positioning locking tongue 211 and the mounting hole can make use of the engagement between the positioning locking tongue 211 and the mounting hole so that the counterweight 2 can be engaged and fixed on the impact plate 4, so that the counterweight 2 and the impact plate 4 form a whole, thereby ensuring the impact effect of the impact hammer 43.

[0047] See also Figure 4 In this embodiment, a reset groove is provided on the side wall of the first positioning groove 214, a reset block 212 is slidably connected in the reset groove, and a reset spring 215 is also provided in the reset groove for driving the positioning lock tongue 211 to automatically pop outward, the reset block 212 is fixedly connected to the positioning lock tongue 211, a second positioning groove 222 is provided on the inner wall of the support groove 22, a slidably connected push rod 221 is provided in the second positioning groove 222, the first positioning groove 214 and the second positioning groove 222 are of the same size and are connected to each other, a fixedly connected baffle 23 is provided in the first positioning groove 214, a fixedly connected and bendable connecting piece 213 is provided at the end of the positioning lock tongue 211, an extending end of the connecting piece 213 movably passes through the baffle 23 and is fixedly connected to the inner wall of the second positioning groove 222 above the baffle 23, a synchronization rod is provided above the baffle 23, one end of the synchronization rod is fixedly connected to the push rod 221, and the other end of the baffle 23 is connected to the corresponding connecting piece 213.

[0048] The design of the push rod 221, baffle 23, connecting piece 213, and synchronous rod can cooperate with the extension and contraction of the support rod 35. After the support rod 35 is extended, the push rod 221 can be squeezed and contracted, and the positioning lock tongue 211 can be driven to contract through the connecting piece 213. At this time, the counterweight block 2 is fixedly mounted on the support block 33 through the support rod 35, and when the counterweight block 2 needs to be separated from the mounting rod 42, the positioning lock tongue 211 can be driven to contract by the extension of the support rod 35, and the fixation between the mounting rod 42 and the counterweight block 2 can be released. Then, the counterweight block 2 can be driven to separate through the conveying ring 3. After the support rod 35 is contracted, the elasticity of the return spring 215 can drive the positioning lock tongue 211 to extend. In this way, when the counterweight block 2 completely falls on the impact plate 4, the elasticity of the return spring 215 can drive the positioning lock tongue 211 to be inserted into the mounting hole, thereby realizing the connection and fixation between the counterweight block 2 and the mounting rod 42, and ensuring the overall stability.

[0049] See also Figure 1 and Figure 5 In this embodiment, the base 1 is provided with four symmetrically distributed and fixedly connected columns 11, the upper ends of the columns 11 are provided with fixedly connected cover plates 15, the impact plate 4 is slidably connected to the corresponding columns 11, the inner walls of the columns 11 are provided with slide grooves 13, the impact plate 4 is provided with sliders 44 slidably connected to the slide grooves 13, the sliders 44 are provided with fixedly connected lifting ropes 45, a rotating shaft 46 rotatably connected is provided between two adjacent columns 11, the extending ends of the lifting ropes 45 are respectively fixedly connected to the corresponding rotating shafts 46, and synchronous chains 47 connected are provided between adjacent rotating shafts 46, a fixedly connected lifting motor 41 is provided at the upper end of the cover plate 15, and the output end of the lifting motor 41 is connected to one of the rotating shafts 46 through a chain.

[0050] The design of the slider 44 and the slide groove 13 can ensure the stability of the impact plate 4 when it falls downward. The design of the lifting rope 45 changes the original one lifting rope 45 to four, which can not only maintain the increase and decrease operation of the counterweight block 2, but also realize the up and down movement of the impact plate 4.

[0051] See also Figure 1 , Figure 2 and Figure 3In this embodiment, two groups of symmetrically distributed and rotatable conveying shafts 32 are provided above the impact plate 4. The conveying shafts 32 are used to drive the conveying ring strips 3 to rotate, and the conveying shafts 32 are respectively connected to the corresponding columns 11 for rotation. A fixedly connected conveying motor 31 is provided on the cover plate 15. The conveying motor 31 is connected to one group of conveying shafts 32 through a chain. The two groups of conveying shafts 32 rotate synchronously in opposite directions through gear connection. A fixedly connected connecting shaft 361 is provided between the columns 11, and the pressing gear 36 is connected to the connecting shaft 361 for rotation. It is a prior art that the conveying shaft 32 drives the two conveying ring strips 3 to rotate synchronously in opposite directions through gears. Therefore, this application does not describe too much about the specific gear connection method.

[0052] See also Figure 1 , Figure 6 In this embodiment, the base 1 is provided with two symmetrically distributed guide grooves 143, the cross-section of the guide groove 143 is convex, the guide groove 143 is provided with two symmetrically distributed and slidably connected guide blocks 141, one side of the guide block 141 is provided with an adjustment groove 142, one end of the extrusion plate 14 is slidably connected to the adjustment groove 142, the upper end of the guide block 141 is provided with a threaded adjustment bolt 144, the adjustment bolt 144 passes through the upper inner wall of the adjustment groove 142, and the bottom of the adjustment bolt 144 is rotatably connected to the extrusion plate 14.

[0053] In this embodiment, there are four mounting holes, and the mounting holes are symmetrically distributed on the counterweight 2.

[0054] When this embodiment is used:

[0055] First, place the plate on the base 1, slide the guide block 141 to a suitable position, and then turn the adjusting bolt 144 to drive the extrusion plate 14 to fix the plate;

[0056] Then, the lifting motor 41 is controlled to drive the impact plate 4 to move upward to a set position, and then the impact plate 4 is allowed to fall freely so that the impact hammer 43 impacts the plate, and the impact is observed and recorded;

[0057] When it is necessary to improve the impact effect, first control the lifting motor 41 to drive the impact plate 4 to move upward to the set position, so that the installation rod 42 is inserted into the limit hole 21, and then control the conveying motor 31 to rotate forward, drive the conveying ring 3 to rotate synchronously in the opposite direction, so that the counterweight block 2 automatically moves downward. When the bottom counterweight block 2 moves to one side of the pressing gear 36, the pressing gear 36 presses the corresponding pressing plate 263, and by pressing the telescopic mechanism 362, the support rod 35 can be driven to automatically contract, so that the support rod 35 is separated from the support groove 22. At this time, the bottom counterweight block 2 is As the support of the support rod 35 is lost, the weight block 2 automatically falls onto the impact plate 4 due to gravity. After the weight block 2 contacts the impact plate 4, the top rod 221 loses the squeezing of the support rod 35. Therefore, under the action of the reset spring 215, the positioning lock tongue 211 automatically pops out and is inserted into the corresponding mounting hole, so that the weight block 2 is connected and fixed to the mounting rod 42 to form a whole. In this way, multiple weight blocks 2 can be quickly added; after the weight block 2 is installed, the impact plate 4 is controlled to move to the set position again, and then it is dropped again to impact the plate, and then observed and recorded;

[0058] When the number of counterweights 2 on the impact plate 4 needs to be reduced, the lifting motor 41 is first controlled to drive the impact plate 4 to move upward to the set position, so that the uppermost counterweight 2 on the impact plate 4 is located at the pressing gear 36, and then the conveying motor 31 is controlled to rotate in the opposite direction. At this time, the pressing mechanism that has been pressed once moves to the pressing gear 36 again. The pressing of the pressing gear 36 again can drive the support rod 35 to automatically extend again, so that the support rod 35 is engaged with the support groove 22. The engagement of the support rod 35 with the support groove 22 can squeeze the top rod 221 to contract, and through the transmission of the connecting piece 213, the positioning lock tongue 211 is driven to separate from the corresponding mounting hole, thereby releasing the fixation between the counterweight 2 and the corresponding mounting rod 42; and with the continuous movement of the conveying ring 3, the uppermost counterweight 2 can be driven to move automatically upward, thereby realizing the separation of the counterweight 2. In this way, the sequential separation of the counterweight 2 can be realized.

[0059] A method for testing the strength of an inorganic material building material board, using the inorganic material building material board strength testing device, comprises the following steps:

[0060] S1 places the plate on the base 1, controls the extrusion plate 14 to fix the plate, and then controls the impact plate 4 to rise to a set height and then move downward, driving the impact hammer 43 to impact the plate;

[0061] S2 then controls the impact plate 4 to rise, so that the mounting rod 42 moves upward and is inserted into the corresponding limiting holes 21 in sequence, and then controls the support rods 35 at both ends of the bottom counterweight block 2 to contract, so that the bottom counterweight block 2 automatically falls onto the impact plate 4. When the counterweight block 2 is completely placed on the impact plate 4, the impact plate 4 is controlled to move to the set position, and then falls again to impact the plate; in this way, the number of counterweight blocks 2 is increased in sequence, the impact force of the impact hammer 43 when colliding is changed, and the impact effect is recorded in sequence;

[0062] S3 When it is necessary to reduce the number of counterweight blocks 2, it is only necessary to control the impact plate 4 to rise to the set height, and control the conveying ring bar 3 to rotate, so that the support blocks 33 move to the two ends of the counterweight blocks 2 at the upper end of the impact plate 4, and then control its support rod 35 to extend so that the support rod 35 engages with the support groove 22, and then control the conveying ring bar 3 to rotate, so that the number of counterweight blocks 2 can be reduced. In this way, the number of counterweight blocks 2 can be reduced successively.
