Description

Technical Field

[0001] The present invention relates to the field of wooden floor detection, and particularly to a device for detecting the mechanical strength of a wooden floor and a detection method thereof. Background Art

[0002] A wooden floor refers to a floor covering material on which people walk, stand, and place furniture and other items. Wooden floors are usually used in indoor spaces, providing a comfortable foot feeling and decorative effect. The strength detection of wooden floors is a common engineering test method used to evaluate the load-bearing capacity and stability of wooden floors. The strength detection of wooden floors is usually divided into pressure detection, impact detection, vibration detection, etc. The strength detection of wooden floors is an essential process before the wooden floors leave the factory. When the existing device for detecting the mechanical strength of a wooden floor is in use, through the mutual cooperation of the material cleaning mechanism and the driving mechanism, it can not only block the outside of the wooden floor during detection to avoid the flying of broken wooden floor debris, but also automatically discharge the broken wooden floors into the collection box after the detection is completed, without the need for the tester to clean. The existing device for detecting the mechanical strength of a wooden floor can also adjust the blanking position of the blanking plate according to the wooden floors of different lengths through the mutual cooperation of structures such as an adjustment frame, a threaded rod, an upper bevel gear, and a lower bevel gear, ensuring that the wooden floors of different lengths can be automatically discharged, improving the application range of the device and increasing the flexibility of the device. When the existing device is in use, although the broken wooden floors can be effectively recycled through the collection box, most of the broken positions of the wooden floors are in the middle of the wooden floors, and it often occurs that the middle position of the wooden floor is broken, but the middle position of the wooden floor is not completely broken, and there is still a little wood bent and connected together at the middle position of the wooden floor. This will cause the broken wooden floors to still rest on the blanking plate and cannot effectively fall into the collection box. Moreover, most of the broken wooden floors that fall into the collection box are half pieces of wooden floors broken in the middle. These half-piece waste wooden floors will quickly fill the collection box, but there will be a large number of gaps between the waste wooden floors, wasting the space of the collection box. Secondly, when recycling these wooden floors, they need to be crushed, which makes it necessary to additionally use a crushing device to crush the waste wooden floors in the collection box when recycling and reusing them, which will affect the work efficiency. For this reason, we propose a device for detecting the mechanical strength of a wooden floor and a detection method thereof. Summary of the Invention

[0005] Preferably: The blanking component includes two groups of connecting plates. The two groups of connecting plates are fixedly installed on the outer wall of the upper box body. Two groups of sliding rods are fixedly installed between the two groups of connecting plates. The two groups of sliding rods both slidably penetrate through the inside of a rack.

[0006] Preferably: The telescopic end of the first hydraulic telescopic cylinder is fixedly connected to a mounting plate. A detection head is fixedly installed at the bottom of the mounting plate.

[0007] Preferably: A high-strength transparent glass is inlaid and installed at the front end of the partition cover. Both ends of the partition cover are open. The open ends of the partition cover are matched with the two groups of fixing plates.

[0008] Preferably: Four groups of guide rods are fixedly installed at the top of the partition cover. The four groups of guide rods all slidably penetrate through the inside of the bracket. Four groups of second springs are arranged between the top of the partition cover and the bracket.

[0009] Preferably: A placing groove is opened on the placing member. A plurality of placing plates are fixedly installed in the placing groove.

[0010] Preferably, the support assembly includes a support connecting member. Two sets of bumps at the lower end of the support connecting member are respectively rotatably connected to a set of hinge seats I. The two sets of hinge seats I are respectively fixedly connected to the telescopic ends of a set of hydraulic telescopic cylinders III. The two sets of hydraulic telescopic cylinders III are respectively fixedly connected to a set of hinge seats II. The two sets of hinge seats II are respectively rotatably connected to a set of fixed seats.

[0011] Preferably, the support connecting member is fixedly installed at the bottom of the lower box body. The two sets of fixed seats are fixedly connected to the support seat, and the support seat is fixedly connected to the outer wall of the upper box body.

[0012] Preferably, two sets of limit sliding grooves are formed in the lower box body. A set of sliders are respectively slidably installed in the two sets of limit sliding grooves. The two sets of sliders are fixedly connected to the extension plate.

[0013] The present invention also provides a detection method for the force-bearing strength detection device of the wooden floor, which is characterized by including the following specific steps:

[0014] S1. During detection, place the wooden floor to be detected in the placement groove and above the placement plate. It should be noted that the exact middle position of the wooden floor is aligned with the detection head. Then start the hydraulic telescopic cylinder I to drive the detection head to move downward. At the same time, under the action of the spring II in the extrusion state, the partition cover will be driven to move downward. Before the detection head contacts the wooden floor, the partition cover will be closed with the two sets of fixed plates, thereby blocking the notch.

[0015] S2. The downward movement of the partition cover cooperates with the two sets of fixing components, so that the four insertion rods are respectively inserted into the four insertion holes formed in the placement member, thereby stably fixing the placement member in the notch.

[0016] S3. When the hydraulic telescopic cylinder I drives the detection head to move downward and contact the wooden floor, the detection head will squeeze and detect the wooden floor downward. After the detection is completed, the broken wooden floor will be in the placement groove. Then the hydraulic telescopic cylinder I drives the detection head and the partition cover to move upward and reset.

[0017] S4. Then, through the blanking component, the placement member is rotated to pour the broken wooden floor in the placement groove into the inner cavity between the upper box body and the lower box body. At this time, start the motor to drive the crushing blade to rotate to crush the broken wooden floor. During crushing, blocked by the placement member, the debris generated by crushing cannot jump out through the notch. Finally, use the support assembly to drive the lower box body to rotate downward to discharge the broken materials.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When the present invention is in use, when the hydraulic telescopic cylinder 1 drives the detection head to move downward, the spring 2 in the extrusion state will drive the partition cover to move downward. When the partition cover moves downward, it will cooperate with the fixing component, so that the four inserting rods can be effectively inserted into the four inserting holes. Moreover, the four inserting rods are horizontally inserted into the inserting holes opened in the placing member, so as to effectively limit and fix and support the placing member, ensuring that the placing member is fixed during detection. By horizontally inserting the four inserting rods into the inserting holes, it is possible to avoid the rotating column alone bearing the downward pressure when the hydraulic telescopic cylinder 1 drives the detection head to move downward, thereby avoiding the fracture of the rotating column due to alone bearing the downward pressure. After detection, when the hydraulic telescopic cylinder 1 drives the detection head to move upward and reset, it can also drive the partition cover and the four inserting rods to complete the reset. Then, through the blanking component, the placing member will rotate 180 degrees, causing the broken wooden floor in the placing groove to fall into the inner cavities of the upper box body and the lower box body, avoiding the situation that the wooden floor that is not completely broken cannot fall into the collection box.

[0020] 2. When the present invention is in use, the motor will drive the crushing blade to rotate. The rotation of the crushing blade will crush the broken wooden floor. And during the crushing process, blocked by the placing member, the crushed debris cannot jump out through the notch. Crushing the broken wooden floor avoids the waste wooden floor occupying a large amount of space in the upper box body and the lower box body, resulting in the operator needing to frequently handle the waste wooden floor in the upper box body and the lower box body. Moreover, the crushed wooden floor waste is also convenient for recycling. BRIEF DESCRIPTION OF THE DRAWINGS

The motor 12 is fixedly installed on the outer wall of the upper box body 1. The upper box body 1 is hinged to a lower box body 13 through a plurality of hinges. A support component 14 is arranged at the bottom of the lower box body 13;

[0031] The fixed component 8 includes a moving member 801, the moving member 801 is fixedly connected to the top end of the partition cover 7, the smooth inclined surface of the moving member 801 is slidably fitted with the smooth inclined surface of the movable member 802, two groups of insertion rods 803 penetrate through the inner side of the movable member 802, the insertion rods 803 slidably penetrate through the inner side of the fixing plate 804 and the inner side of the bracket 5, two groups of first springs 805 are arranged between the fixing plate 804 and the movable member 802, and the insertion rods 803 are matched with the insertion holes 15 formed in the placing member 4.

[0032] The blanking component 9 includes two groups of connecting plates 901, the two groups of connecting plates 901 are fixedly installed on the outer wall of the upper box body 1, two groups of sliding rods 902 are fixedly installed between the two groups of connecting plates 901, both of the two groups of sliding rods 902 slidably penetrate through the inner side of the rack 903, a second hydraulic telescopic cylinder 905 is fixedly installed on one group of connecting plates 901, the telescopic end of the second hydraulic telescopic cylinder 905 is fixedly connected to the rack 903, the rack 903 meshes with the gear 904, the gear 904 is fixedly installed on the outer wall of the rotating column 3, a first limiting ring 906 is fixedly installed on the outer walls of both of the two groups of sliding rods 902, and a second limiting ring 907 is fixedly installed on the outer walls of both of the two groups of sliding rods 902; after the detection is completed, the broken wooden floor is in the placing groove 20. When it is necessary to discharge the broken wooden floor in the placing groove 20 into the inner cavities of the upper box body 1 and the lower box body 13, starting the second hydraulic telescopic cylinder 905 can drive the rack 903 to move. One end of the rack 903 will drive the gear 904 to rotate, the rotation of the gear 904 will drive the rotating column 3 to rotate, the rotation of the rotating column 3 will drive the placing member 4 to rotate until the rack 903 contacts the second limiting ring 907. At this time, the placing member 4 will rotate 180 degrees, and the broken wooden floor in the placing groove 20 will fall into the inner cavities of the upper box body 1 and the lower box body 13; it should be noted that when the rack 903 contacts the first limiting ring 906, the placing member 4 is in a horizontal state. At this time, the four insertion rods 803 can be respectively inserted into the four insertion holes 15 formed in the placing member 4.

[0033] The telescopic end of the first hydraulic telescopic cylinder 6 is fixedly connected to the mounting plate 16, and a detection head 17 is fixedly installed at the bottom of the mounting plate 16; during use, after the detection head 17 moves down to contact the wooden floor, the detection head 17 will squeeze and detect the wooden floor downward. It should be noted that the inspection head 17 is a prior art and is the same as the detection head in a wooden floor stress intensity detection device with the publication number CN118857926B. Therefore, the detailed contact principle of the inspection head 17 will not be described in detail here. For details, refer to the detection head in a wooden floor stress intensity detection device with the publication number CN118857926B.

[0034] The front end of the partition cover 7 is inlaid with a high-strength transparent glass 26. Both ends of the partition cover 7 are open. The openings at both ends of the partition cover 7 are matched with two groups of fixed plates 804. Through the high-strength transparent glass 26, the process of detecting the wooden floor can be observed. When the partition cover 7 moves down and closes with the two groups of fixed plates 804, a cover is formed by the partition cover 7, the two groups of fixed plates 804 and the high-strength transparent glass 26 to prevent the splashing of broken wooden boards during detection from hurting people.

[0035] Four groups of guide rods 18 are fixedly installed at the top of the partition cover 7. All four groups of guide rods 18 slide through the inside of the bracket 5. Four groups of second springs 19 are arranged between the top of the partition cover 7 and the bracket 5. During use, the partition cover 7 moves up and down stably through the guide rods 18. It should be noted that when the bottom of the partition cover 7 touches the top of the upper box body 1, the second spring 19 is still in a compressed state.

[0036] A placement groove 20 is formed in the placement member 4, and multiple placement plates 21 are fixedly installed in the placement groove 20. During detection, the wooden floor to be detected is placed in the placement groove 20 and above the placement plates 21. It should be noted that the middle position of the wooden floor is aligned with the detection head 17.

[0037] The support assembly 14 includes a support connecting member 1401. Two convex blocks at the lower end of the support connecting member 1401 are respectively rotatably connected to a group of first hinge seats 1402. The two groups of first hinge seats 1402 are respectively fixedly connected to the telescopic ends of a group of third hydraulic telescopic cylinders 1403. The two groups of third hydraulic telescopic cylinders 1403 are respectively fixedly connected to a group of second hinge seats 1404. The two groups of second hinge seats 1404 are respectively rotatably connected to a group of fixed seats 1405. When the amount of wood floor debris in the inner cavities of the upper box body 1 and the lower box body 13 reaches a certain amount, the third hydraulic telescopic cylinders 1403 are started to contract. At this time, the lower box body 13 will rotate downward along the upper box body 1, as shown in the appendix Figure 2 shown.

[0038] The support connecting member 1401 is fixedly installed at the bottom of the lower box body 13. The two groups of fixed seats 1405 are fixedly connected to the support seat 22, and the support seat 22 is fixedly connected to the outer wall of the upper box body 1, making the connection structure of the device stable.

[0039] Two groups of limit sliding grooves 23 are formed in the lower box body 13. A group of sliders 24 are respectively slidably installed in the two groups of limit sliding grooves 23. The two groups of sliders 24 are fixedly connected to the extension plate 25. When the lower box body 13 rotates downward, the extension plate 25 can be pulled, as shown in the appendix Figure 2 shown. At this time, the wood floor debris in the lower box body 13 can slide downward along the lower box body 13 and the extension plate 25 and be discharged.

[0040] The present invention also provides a detection method for the wooden floor stress intensity detection device, which is characterized by including the following specific steps:

[0041] S1. During detection, place the wooden floor to be detected in the placement groove 20 and above the placement plate 21. It should be noted that the exact middle position of the wooden floor is aligned with the detection head 17. Then, start the first hydraulic telescopic cylinder 6, which will drive the detection head 17 to move downward. At the same time, under the action of the second spring 19 in the extrusion state, the partition cover 7 will be driven to move downward. Before the detection head 17 touches the wooden floor, the partition cover 7 will be closed with the two groups of fixed plates 804, thereby covering the notch 2.

[0042] S2. The downward movement of the partition cover 7 cooperates with the two groups of fixing components 8, so that the four insertion rods 803 are respectively inserted into the four insertion holes 15 opened on the placement member 4, thereby stably fixing the placement member 4 in the notch 2.

[0043] S3. When the first hydraulic telescopic cylinder 6 drives the detection head 17 to move downward and contact the wooden floor, the detection head 17 will press and detect the wooden floor downward. After the detection is completed, the broken wooden floor will be in the placement groove 20. Then, the first hydraulic telescopic cylinder 6 drives the detection head 17 and the partition cover 7 to move upward and reset.

[0044] S4. Then, the placement member 4 is rotated through the blanking component 9 to pour the broken wooden floor in the placement groove 20 into the inner cavity between the upper box body 1 and the lower box body 13. At this time, start the motor 12 to drive the crushing blade 11 to rotate to crush the broken wooden floor. During crushing, blocked by the placement member 4, the debris generated by crushing cannot jump out through the notch 2. Finally, the support component 14 drives the lower box body 13 to rotate downward to discharge the broken materials.

[0045] Working principle of the present invention: During detection, the wooden floor to be detected is placed in the placement groove 20 and above the placement plate 21. It should be noted that the exact middle position of the wooden floor is aligned with the detection head 17. Then, starting the first hydraulic telescopic cylinder 6 will drive the detection head 17 to move downward. At the same time, under the action of the second spring 19 in the extrusion state, the partition cover 7 will be driven to move downward. The downward movement of the partition cover 7 will drive the two moving parts 801 to move downward. Since the smooth inclined surface of the moving part 801 slides and fits with the smooth inclined surface of the movable part 802, the downward movement of the moving part 801 squeezes the movable part 802, causing the movable part 802 to move in the direction close to the fixed plate 804. The movement of the movable part 802 will drive the insertion rod 803 to insert into the corresponding jack 15. During this process, the first spring 805 is squeezed until the bottom of the partition cover 7 contacts the top of the upper box body 1. At this time, the four insertion rods 803 are effectively inserted into the four jacks 15, and thus the placement part 4 can be effectively limited and fixed; it should be noted that the insertion rod 803, the rotating column 3, the placement part 4 and the placement plate 21 are all made of stainless steel, so that when the detection head 17 squeezes and detects the wooden floor downward, the insertion rod 803, the rotating column 3, the placement part 4 and the placement plate 21 will not be deformed by force, and the second spring 19 and the first spring 805 respectively adopt springs that meet the usage requirements;

[0046] When the bottom of the partition cover 7 contacts the top of the upper box body 1, at this time, the partition cover 7 cannot continue to move downward, and when the partition cover 7 and the two fixed plates 804 are closed at this time, a cover is formed by the partition cover 7, the two fixed plates 804 and the high-strength transparent glass 26 to prevent the broken wooden boards from splashing and hurting people during detection; then start the first hydraulic telescopic cylinder 6 to drive the detection head 17 to continue to move downward. After the detection head 17 moves downward and contacts the wooden floor, the detection head 17 will squeeze and detect the wooden floor downward. After the detection is completed, the broken wooden floor will be in the placement groove 20;

[0047] After the detection is completed, start the first hydraulic telescopic cylinder 6 to drive the mounting plate 16 and the detection head 17 to move upward and reset. When the mounting plate 16 moves upward and contacts the partition cover 7, it will drive the partition cover 7 to move upward and reset. At this time, the squeezed first spring 805 will gradually drive the insertion rod 803 to move back to its original position, so that the insertion rod 803 disengages from the jack 15. After the detection head 17 and the partition cover 7 are reset, start the second hydraulic telescopic cylinder 905 to drive the rack 903 to move. One end of the rack 903 will drive the gear 904 to rotate. The rotation of the gear 904 will drive the rotating column 3 to rotate. The rotation of the rotating column 3 will drive the placement part 4 to rotate until the rack 903 contacts the second limit ring 907. At this time, the placement part 4 will rotate 180 degrees, and the broken wooden floor in the placement groove 20 will fall into the inner cavities of the upper box body 1 and the lower box body 13;

[0048] When a broken wooden floor falls into the inner cavities of the upper box body 1 and the lower box body 13, starting the motor 12 will drive the crushing shaft 10 to rotate. The rotation of the crushing shaft 10 will drive the crushing blades 11 to rotate, and the rotation of the crushing blades 11 will crush the broken wooden floor. During the crushing process, blocked by the placing member 4, the debris generated by crushing cannot jump out through the notch 2. When the amount of wooden floor scraps in the inner cavities of the upper box body 1 and the lower box body 13 reaches a certain amount, start to contract the two groups of hydraulic telescopic cylinders three 1403 at the same time. At this time, the lower box body 13 will rotate downward along the upper box body 1. When the lower box body 13 rotates downward, it can pull the extension plate 25, as shown in the appendix Figure 2 As shown, at this time, the wooden floor debris in the lower box body 13 can slide downward along the lower box body 13 and the extension plate 25 and be discharged.

[0049] It should be noted that the motor 12, the hydraulic telescopic cylinder one 6, the hydraulic telescopic cylinder two 905 and the hydraulic telescopic cylinder three 1403 all belong to the prior art. Among them, the motor is a kind of motor that can convert alternating current electrical energy into mechanical energy. The basic working principle of an alternating current motor is to use the magnetic field generated when the current passes through a conductor to drive the rotor to rotate. When the motor 12 is used, it needs to be connected to a suitable power supply with a special controller to be used. Among them, the hydraulic telescopic cylinder is a common hydraulic actuator, which is widely used in engineering machinery, automation equipment and other fields. It uses the hydraulic principle to achieve telescopic movement. The hydraulic telescopic cylinder one 6, the hydraulic telescopic cylinder two 905 and the hydraulic telescopic cylinder three 1403 all need to be used together with a special hydraulic pump, hydraulic pipeline, etc. It should be especially noted that the two groups of hydraulic telescopic cylinders three 1403 are connected to the same oil source through a synchronous valve, and at the same time, a PLC control system is used to ensure that the two hydraulic telescopic cylinders three 1403 expand and contract at the same moment through programming.

[0050] The above content is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or replacements can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted by the present invention.
