Description

Technical Field

[0001] The present invention relates to the technical field related to the impact detection of building materials, and particularly relates to an impact resistance detection device for building material processing. Background Art

[0002] Building materials is a general term for materials used in civil engineering and construction engineering, including wood, bamboo, stone, cement, concrete, metal, bricks and tiles, ceramics, glass, engineering plastics, composite materials, etc. In order to ensure the project quality and use safety, it is also necessary to detect the impact resistance of building materials.

[0003] In the prior art, when detecting small-sized building materials such as bricks and tiles and ceramics, sand is mostly used as the bottom material during the impact detection of building materials. However, after the detection, the surface of the sand pile will become uneven, and some of the debris left after the building materials are broken is difficult to clean up. These will all affect the subsequent detection of building materials, making it difficult to use this economical and convenient detection method when conducting impact detection on a large number of building materials. Summary of the Invention

[0004] The main purpose of the present invention is to provide an impact resistance detection device for building material processing, which can effectively solve the problems of the uneven surface of the sand pile and the difficulty in cleaning the residual debris of building materials.

In the upper part of the horizontal part in the middle of the inner cavity of the rectangular frame-shaped box body, there are two right-angled trapezoidal partitions. The two right-angled trapezoidal partitions divide the upper part of the inner cavity of the rectangular frame-shaped box body into a detection cavity and two storage cavities. The detection cavity is located between the two storage cavities. The inner sides of the detection cavity and the two storage cavities are filled with fine sand used as a padding protection device. At the bottom of the inner cavity of the rectangular frame-shaped box body, there is an electric push rod and two U-shaped hydraulic telescopic components. The electric push rod is located between the two U-shaped hydraulic telescopic components. The output end of the electric push rod extends into the detection cavity and is provided with a second push plate. The telescopic components of the vertical parts of the two U-shaped hydraulic telescopic components away from each other respectively extend into the storage cavity on the same side and are both provided with a first push plate. In the upper part of the inner cavity of the rectangular frame-shaped box body, there are two moving mechanisms for拨动转移细沙 (the specific meaning of this part needs to be further clarified according to the context, tentatively translated as "stirring and transferring fine sand"). In the upper part of the front end of the rectangular frame-shaped box body, there is a control mechanism for controlling the two moving mechanisms to move in a rectangular trajectory. On the upper parts of the left end and the right end of the rectangular frame-shaped box body, there are two first bearing plates on each side. The upper ends of the two first bearing plates on the same side are jointly provided with a screening mechanism for separating the building material fragments mixed in the fine sand.

[0007] Preferably, a receiving groove is formed in the upper part of one end of the right-angled trapezoidal partition close to the screening mechanism.

Two springs are jointly arranged between one end of the baffle away from the screening mechanism and the inner wall of the receiving groove.

[0008] Preferably, the screening mechanism includes a mounting box slidably connected to the first bearing plate. A T-shaped filter screen frame and a horizontally placed rotating rod are arranged inside the mounting box. The horizontal part of the T-shaped filter screen frame passes through the side walls of the mounting box and the H-shaped box body and extends into the receiving cavity on the same side. The side of the horizontal part of the T-shaped filter screen frame away from its vertical part is slidably connected to the receiving groove. Four pressing cams for forcing the T-shaped filter screen frame to vibrate are arranged on the outer surface of the rotating rod. One side of one end of the mounting box close to the H-shaped box body is provided with a first transmission rod. The end of the first transmission rod away from the H-shaped box body extends into the mounting box and is jointly provided with a bevel gear set with one end of the rotating rod.

[0009] Preferably, the protruding parts of the two pressing cams located in the middle position are opposite to the protruding parts of the remaining two pressing cams in terms of orientation.

[0010] Preferably, a second bearing plate is arranged on the outer wall of one side of the H-shaped box body. A motor is arranged at the upper end of the second bearing plate. A gear transmission box is arranged at the output end of the motor and is fixedly connected to the second bearing plate. Transmission rods are arranged on both the left and right sides of the gear transmission box. The motor controls the rotation of the two transmission rods through the gear transmission box. A rectangular telescopic rod is jointly arranged between the ends of the transmission rod and the first transmission rod close to each other, and the telescopic component of the rectangular telescopic rod is a horizontally separable structure.

[0011] Preferably, a spur gear is arranged on the outer wall of the side of the H-shaped box body away from the motor. Rack teeth are arranged at the ends of the two mounting boxes away from each other, and the rack teeth are located on the side of the mounting box away from the first transmission rod. The two rack teeth are respectively located above and below the spur gear, and both rack teeth are meshed with the spur gear.

[0012] Preferably, the operating mechanism includes a rectangular frame slidably connected to the outer wall of the H-shaped box body. Two symmetrically distributed square frames are arranged inside the rectangular frame. An equal-width cam is arranged inside the square frame. A transmission shaft is arranged at one of the corners of the end of the equal-width cam away from the H-shaped box body.

[0013] A gear transmission box connected to the output end of the motor and the two transmission shafts is arranged at the upper end of the second bearing plate. The motor controls the rotation of the two equal-width cams in opposite directions through the gear transmission box and the transmission shafts.

[0014] Preferably, the moving mechanism includes a third push plate located at the upper part of the inner cavity of the rectangular box with a shape like a Chinese character 'Ri'. The bottom of the third push plate is a triangular structure for facilitating insertion into the sand pile.

The horizontal part at the lower part of the U-shaped slide plate is horizontally slidably connected to the square frame on the same side, and a plug bolt for fixing the U-shaped slide plate and the square frame is provided at the bottom of the vertical part of the U-shaped slide plate.

[0015] Preferably, when the third push plate moves down to the maximum distance, the bottom of the third push plate and the top of the right-angled trapezoidal partition are at the same horizontal height.

[0018] By setting up a screening mechanism, a motor and other structures, the present invention facilitates screening fine sand during the process of transferring the fine sand in the detection cavity, removing building material fragments with smaller volume mixed in the fine sand, and at the same time restoring the fine sand to a loose state, minimizing the impact of the fine sand becoming compact due to impact in the detection cavity, thereby improving the accuracy of the detection data.

[0019] By setting up a moving mechanism, an operating mechanism and other structures, the moving mechanism of the present invention can not only act as the side wall of the detection cavity when the building material is subjected to impact detection, reducing the possibility of fragments flying out and hurting the surrounding staff when the building material breaks, but also move in a rectangular trajectory to assist in transferring the fine sand, and at the same time can level the surface of the sand pile in the detection cavity, thereby reducing errors and ensuring the standardization and repeatability of the detection.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0031] like Figure 1-Figure 3As shown in the figure, this embodiment discloses an impact resistance detection device for building material processing, including a box body 1 in the shape of a Chinese character "ri". The top of the box body 1 in the shape of a Chinese character "ri" is an open structure for convenient placement and removal of building materials. At the upper end of the horizontal part in the middle of the inner cavity of the box body 1 in the shape of a Chinese character "ri", there are two right trapezoidal partitions 13. The two right trapezoidal partitions 13 divide the upper part of the inner cavity of the box body 1 in the shape of a Chinese character "ri" into a detection cavity and two storage cavities, so as to make the fine sand in the detection cavity enter the two storage cavities as much as possible by using the top inclined surface of the right trapezoidal partition 13. The detection cavity is located between the two storage cavities. The inner sides of the detection cavity and the two storage cavities are filled with fine sand used as padding to protect the device, so as to avoid the loss of fine sand in the detection cavity when the fine sand in the storage cavity is pushed back into the detection cavity, which affects the accuracy of the data. At the bottom of the inner cavity of the box body 1 in the shape of a Chinese character "ri", there are an electric push rod 11 and two U-shaped hydraulic telescopic components 9, and the vertical parts of the U-shaped hydraulic telescopic components 9 are telescopic structures. The inner sides of the horizontal parts and one of the vertical part pipes of the U-shaped hydraulic telescopic components 9 are filled with hydraulic oil, so as to make the two vertical parts expand and contract in a staggered manner by the flow of the hydraulic oil. The electric push rod 11 is located between the two U-shaped hydraulic telescopic components 9. The output end of the electric push rod 11 extends into the detection cavity and is provided with a second push plate 12. The telescopic components of the vertical parts of the two U-shaped hydraulic telescopic components 9 away from each other respectively extend into the storage cavities on the same side and are both provided with a first push plate 10, as Figure 1 and Figure 2 shown, on the upper parts of the left end and the right end of the box body 1 in the shape of a Chinese character "ri", there are two first bearing plates respectively. The upper ends of the two first bearing plates on the same side are jointly provided with a screening mechanism 4 for separating building material fragments mixed in the fine sand;

[0032] On the outside of the box body 1 in the shape of a Chinese character "ri", there is also an electromagnetic control component 2 for adsorbing metal balls, which is a commonly used existing technology in impact detection, so that the metal balls can suddenly fall from different heights to impact the building materials placed in the detection cavity;

[0033] As can be seen from the above, after placing the building materials on the sand pile in the detection cavity, the electromagnetic control component 2 is used to make the metal balls suddenly fall to impact the building materials. If the building materials are broken, first take out the larger fragments, and then the electric push rod 11 starts to extend, pushing the second push plate 12 upward. Then the first push plate 10 will move downward due to the loss of support, so that the fine sand in the detection cavity can cross the right trapezoidal partition 13 and fall into the storage cavity. During this process, the fine sand will also pass through the screening mechanism 4 to separate the small fragments that are not easy to find, and at the same time make the fine sand become loose again, as much as possible reducing the influence brought by the fine sand becoming compact due to the impact in the detection cavity. Finally, the electric push rod 11 starts to contract, and by using the flow and extrusion of the hydraulic oil, the first push plate 10 starts to move upward to push the fine sand back into the detection cavity, and then level the surface of the sand pile to carry out the subsequent impact detection of the building materials.

[0034] Further, such as Figure 3 and Figure 4 As shown, when the push plate 2 12 moves down the maximum distance, the push plate 10 moves to the corner of the vertical surface and the inclined surface of the right-angle trapezoidal partition 13 to prevent the fine sand in the storage chamber from falling to the lower side of the push plate 10 after the push plate 10 moves up, thereby affecting the return movement of the push plate 10.

[0035] In order to prevent the fine sand from bypassing the screening mechanism 4 and directly entering the storage chamber, a storage groove 14 is provided on the upper part of one end of the right-angled trapezoidal partition 13 close to the screening mechanism 4, and a baffle 16 for blocking the storage groove 14 is provided on the inner side of the storage groove 14, and two springs 15 are provided between the end of the baffle 16 away from the screening mechanism 4 and the inner wall of the storage groove 14;

[0036] Specifically, Figure 5 and Figure 8 As shown, the screening mechanism 4 includes an installation box 41 slidably connected to the carrier plate 1. In order to prevent the subsequent T-shaped filter frame 46 from pushing the installation box 41 out in the opposite direction under the action of the spring 15, the friction between the carrier plate 1 and the installation box 41 can be increased by applying an anti-slip coating on the carrier plate 1, or the installation box 41 and the Japanese-shaped box body 1 can be temporarily fixed together by a locking assembly. This is a simple prior art, so it is not described in detail. The inner cavity of the installation box 41 is provided with a T-shaped filter frame 46 and a horizontally placed rotating rod 44. The horizontal part of the T-shaped filter frame 46 passes through the side walls of the installation box 41 and the Japanese-shaped box body 1 and extends to the storage cavity on the same side. The horizontal part of the net frame 46 is a frame structure with a filter installed, and the filter is located at the bottom of the frame structure to collect small fragments of building materials. In addition, the top of the inner wall of the frame structure is a chamfered inclined surface structure to reduce the residual fine sand. The side of the horizontal part of the T-shaped filter frame 46 away from its vertical part is slidably connected in the storage groove 14, and the outer surface of the rotating rod 44 is provided with four extrusion cams 45 for forcing the T-shaped filter frame 46 to shake. A transmission rod 43 is provided on one side of the installation box 41 close to one end of the Japanese-shaped box body 1. The transmission rod 43 extends from one end of the Japanese-shaped box body 1 to the installation box 41 and is provided with a bevel gear set 42 together with one end of the rotating rod 44.

[0037] Furthermore, the convex parts of the two squeezing cams 45 located in the middle position are in the opposite direction to the convex parts of the remaining two squeezing cams 45, so as to increase the shaking frequency of the T-shaped filter frame 46 and improve the screening efficiency of fine sand;

[0038] Specifically, Figure 2 and Figure 6As shown in the figure, a second bearing plate is provided on one outer wall of the "day"-shaped box body 1. An electric motor 8 is provided at the upper end of the second bearing plate. A gear transmission box 17 is provided at the output end of the electric motor 8. The gear transmission box 17 is composed of three meshing bevel gears and an outer box, which is a commonly used transmission component. The gear transmission box 17 is fixedly connected to the second bearing plate. Transmission rods II 18 are provided on both the left and right sides of the gear transmission box 17. The electric motor 8 controls the rotation of the two transmission rods II 18 through the gear transmission box 17. A rectangular telescopic rod 19 is jointly provided between the ends of the transmission rod II 18 and the transmission rod I 43 that are close to each other. The telescopic component of the rectangular telescopic rod 19 is a horizontally split structure, that is, the screening mechanism 4 can be disconnected from the gear transmission box 7 by moving away from the "day"-shaped box body 1;

[0039] As can be seen from the above, the gear transmission box 7 controls the rotation of the rotating rod 44 through transmission components such as the gear transmission box 17, the transmission rod II 18, the rectangular telescopic rod 19, the transmission rod I 43, and the bevel gear set 42. Then, the rotating rod 44 continuously pushes the T-shaped filter screen frame 46 through the pressing cam 45. At the same time, using the spring 15, the T-shaped filter screen frame 46 can shake at a certain frequency, accelerating the falling of the fine sand, improving the screening efficiency, and reducing the risk of filter screen rupture.

[0040] Furthermore, as Figure 1 and Figure 5 shown in the figure, a spur gear 3 is provided on the outer wall of the "day"-shaped box body 1 away from the electric motor 8. Rack bars 47 are provided at the ends of the two mounting boxes 41 that are away from each other, and the rack bars 47 are located on the side of the mounting box 41 away from the transmission rod I 43. The two rack bars 47 are respectively located on the upper and lower sides of the spur gear 3. The two rack bars 47 are both meshed with the spur gear 3, so as to use the spur gear 3 and the two rack bars 47 to enable the two screening mechanisms 4 to move in opposite directions simultaneously, reducing the operation steps and improving the work efficiency.

[0041] Therefore, the specific implementation method of this embodiment is:

[0042] When the electric push rod 11 controls the push plate II 12 to move upward, the push plate I 10 will also move downward due to the loss of support, so that the fine sand accumulated on the push plate I 10 can move to the lower side of the horizontal part of the T-shaped filter screen frame 46. Then, before the sand pile on the push plate II 12 crosses the right-angled trapezoidal partition 13, it pushes the mounting box 41 to move towards the "day"-shaped box body 1, so that the horizontal part of the T-shaped filter screen frame 46 is inserted into the storage groove 14. Then, the electric motor 8 is started, and the rotating rod 44 is controlled to rotate through transmission components such as the gear transmission box 17 and the bevel gear set 42. Then, the rotating rod 44 continuously pushes the T-shaped filter screen frame 46 through the pressing cam 45. At the same time, using the spring 15, the T-shaped filter screen frame 46 can shake at a certain frequency to screen the fine sand transferred from the detection cavity, thereby accelerating the falling of the fine sand, improving the screening efficiency, and preventing the filter screen from rupturing. Embodiment

[0043] On the basis of the first embodiment, this embodiment adds a moving mechanism 5 and a manipulating mechanism 6 to facilitate the auxiliary transfer of fine sand back and forth between the detection cavity and the two storage cavities, and at the same time level the surface of the sand pile in the detection cavity to avoid affecting the subsequent impact detection of building materials. As Figure 2 and Figure 7 shown, a manipulating mechanism 6 for controlling the two moving mechanisms 5 to move in a rectangular trajectory is provided at the upper part of the front end of the rectangular-shaped box body 1. The manipulating mechanism 6 includes a rectangular frame 61 slidably connected to the outer wall of the rectangular-shaped box body 1. The rectangular frame 61 can only move vertically up and down. Two symmetrically distributed square frames 62 are provided inside the rectangular frame 61. An equal-width cam 64 is provided inside the square frame 62. A transmission shaft 63 is provided at one of the corners at the end of the equal-width cam 64 away from the rectangular-shaped box body 1;

[0044] A gear transmission box 7 connected to the output end of the motor 8 and the two transmission shafts 63 is provided at the upper end of the bearing plate two. The gear transmission box 7 is a commonly used gear transmission component in the prior art, so it will not be described in detail here. The motor 8 controls the two equal-width cams 64 to rotate in opposite directions through the gear transmission box 7 and the transmission shaft 63;

[0045] As can be seen from the above, the motor 8 controls the two equal-width cams 64 to rotate in opposite directions through the gear transmission box 7 and the two transmission shafts 63. Then, the equal-width cam 64 first controls the rectangular frame 61 to move up through the square frame 62, then separately controls the square frame 62 to move horizontally, then makes the square frame 62 and the rectangular frame 61 move down together, and finally separately controls the square frame 62 to move horizontally and reset, so that the square frame 62 moves in a rectangular trajectory under the rotation and pushing of the equal-width cam 64.

[0046] Specifically, as Figure 7 shown, two moving mechanisms 5 for拨动转移细沙 are provided in the upper part of the inner cavity of the rectangular-shaped box body 1. The moving mechanism 5 includes a pushing plate three 51 located in the upper part of the inner cavity of the rectangular-shaped box body 1. The bottom of the pushing plate three 51 is a triangular structure for conveniently inserting into the sand pile. One end of the pushing plate three 51 close to the manipulating mechanism 6 is provided with a U-shaped sliding plate 52. The horizontal part at the lower part of the U-shaped sliding plate 52 is horizontally slidably connected to the square frame 62 on the same side. A plugging bolt 53 for fixing the U-shaped sliding plate 52 and the square frame 62 is provided at the bottom of the vertical part of the U-shaped sliding plate 52. The moving range of the pushing plate three 51 can be changed by changing the position of the U-shaped sliding plate 52 on the square frame 62, so that the U-shaped sliding plate 52 can not only push all the sand piles on the pushing plate two 12 into the two storage cavities, but also push the sand piles in the pushing plate one 10 back into the detection cavity.

[0047] Furthermore, as Figure 8 and Fig. 9 As shown, when the pushing plate three 51 moves down the maximum distance, the bottom of the pushing plate three 51 and the top of the right-angled trapezoidal partition 13 are at the same horizontal height, so that the two pushing plates three 51 can be tightly attached to the right-angled trapezoidal partition 13 to separate the detection chamber and the storage chamber, thereby preventing the fine sand on the pushing plate one 10 from continuing to flow into the detection chamber when the pushing plate two 12 moves to the bottom of the detection chamber, thereby changing the amount of fine sand in the detection chamber and affecting the detection data. At the same time, it can also serve as the side wall of the detection chamber, thereby reducing the possibility of fragments splashing out and injuring surrounding staff when building materials are broken, and all the fine sand on the pushing plate two 12 can be pushed into the two storage chambers, thereby preventing some building material fragments from being left in the detection chamber and affecting the accuracy of the detection data.

[0048] Therefore, the specific implementation of this embodiment is:

[0049] When the motor 8 controls the screening mechanism 4 to perform screening, it also controls the two equal-width cams 64 to rotate in opposite directions through the gear transmission box 7 and the two transmission shafts 63. Then the equal-width cams 64 rotate and push the square frame 62 to move in a rectangular track. After that, the square frame 62 drives the two push plates 3 51 through the U-shaped slide plate 52, first moving up to fit closely, then moving down to insert into the sand pile on the push plate 2 12, and then separating and pushing the fine sand into the two storage chambers for screening.

[0050] When the fine sand is to be pushed back into the detection chamber, when the two pushing plates three 51 are merged together, the U-shaped slide plate 52 is slid to make the two pushing plates three 51 move away from each other, and then the two equal-width cams 64 are controlled to rotate in opposite directions, so that the pushing plates three 51 move in a rectangular trajectory above the storage chamber, and the part of the fine sand located above the horizontal plane of the top of the right-angled trapezoidal partition 13 is pushed back into the detection chamber. After the part of the space in the detection chamber above the pushing plate 10 is filled with fine sand, the U-shaped slide plate 52 is moved back to the initial position from the square frame 62, and then the pushing plates three 51 are continued to be controlled to move in the initial rectangular trajectory, while pushing the excess fine sand in the detection chamber into the storage container, and at the same time flattening the surface of the sand pile, so as to facilitate the impact detection of the remaining building materials and ensure the accuracy of the detection data.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
