Description
Technical Field
[0001] The utility model relates to the technical field of detection, in particular to a multi-station permeable brick strength detection device. Background Art
[0002] Permeable bricks have good water permeability and can make the accumulated water after rain quickly infiltrate through the pores. Therefore, they are widely used in the construction of sponge cities, alleviating the problem of urban waterlogging after heavy rains. In the production process of permeable bricks, there are permeable bricks of poor quality and easy to break. Direct use will cause risks such as building collapse and safety hazards, so it is necessary to conduct strength testing on the permeable bricks after production.
[0003] For example, a multi-station permeable brick strength testing equipment with application number 202020864170.5, the utility model discloses a strength testing device for permeable brick production, including a bottom plate, a switch, a handle, a pressure plate, a first support plate, a second support plate, a top plate and a first cross plate. The motor is rotated to drive the lead screw to rotate, thereby further driving the first support device and the second support device to move toward each other. A baffle is provided to limit the permeable brick to prevent the permeable brick from moving during the strength testing process, thereby ensuring the stability of the testing process. The threaded rod is further rotated by the handle to push the first cross plate to move downward and further drive the pressure plate to move downward until it contacts the surface of the permeable brick. The handle is further rotated to further push the first cross plate to move downward and compress the spring. When the first cross plate moves downward to the lowest position, if the permeable brick is not damaged at this time, it is qualified. The operation is simple and quick.
[0004] The above patent lacks protective measures. During the strength test of multiple permeable bricks, if the permeable bricks are broken due to unqualified quality, the permeable brick fragments may splash and injure the staff, posing a safety hazard. In addition, after the strength test of the permeable bricks is completed, there will be residual broken bricks on the surface of the permeable bricks due to unqualified quality.

[0029] The clamping assembly 3 includes a bidirectional screw 31, which is rotatably connected to the inner wall of the slide groove 11, and one end of the bidirectional screw 31 passes through the inner wall of the slide groove 11 and is fixedly connected to a handle 32.

Each slider 33 is in contact with the inner wall of the slide groove 11 to prevent the slider 33 from rotating during movement and causing an impact. The side walls of each slider 33 are symmetrically fixedly connected with a first spring 34. The two first springs 34 on the same side are jointly fixedly connected with a clamping plate 35. Each clamping plate 35 is an inverted U-shaped structure. By setting the clamping plate 35 to an inverted U-shaped structure, the contact surface between the clamping plate 35 and the permeable brick 4 is larger, thereby making the clamping effect more stable, and in close contact with the side walls of multiple permeable bricks 4, each clamping plate 35 is slidably connected to the top of the detection table 1.
[0030] The detection component 6 includes a connecting plate 61, which is fixedly connected to the inner wall of the protective cover 5.

[0031] In this embodiment: first, a plurality of permeable bricks 4 are horizontally sent to the middle position of the inspection table 1 through the feeding hole 51, and then the hand 32 is turned forward, and the bidirectional lead screw 31 is rotated by the rotation of the hand 32, so that the two sliders 33 threadedly connected to the side walls of the bidirectional lead screw 31 are close to each other along the slide groove 11, until the two U-shaped clamping plates 35 are in contact with the side walls of the plurality of permeable bricks 4, wherein each clamping plate 35 is fixedly connected to the adjacent sliders 33 by a plurality of first springs 34, so that during the clamping process, the elastic effect of the first springs 34 is utilized to avoid damage to the permeable bricks 4 caused by excessive clamping force; after the permeable bricks 4 are clamped and fixed, the first motor 63 is started, and the first motor 63 is operated to drive The rotating shaft 64 and the cam 65 on the side wall of the rotating shaft 64 rotate. During the rotation process, when the raised end of the cam 65 contacts the top plate 67, it drives the top plate 67, multiple slide bars 66, the bottom plate 69 and the detection head to move upward, and compresses the second spring 68 set on the side wall of each slide bar 66. When the raised end of the cam 65 does not contact the top plate 67, under the elastic action of the multiple second springs 68, the top plate 67, multiple slide bars 66 and the bottom plate 69 are driven to move downward, so that the multiple detection heads at the bottom end of the bottom plate 69 collide with the permeable brick 4, thereby performing strength testing. During the testing process, if the permeable brick 4 is not broken, the quality is qualified. On the contrary, if the permeable brick 4 is broken, it means that the quality is unqualified.
[0032] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 4-7 The cleaning component 7 includes a second motor 71, which is fixedly connected to the side wall of the protective cover 5. The output end of the second motor 71 is fixedly connected to a lead screw 72, one end of which penetrates through one side wall of the protective cover 5 and is rotatably connected to the other inner wall of the protective cover 5. A slide plate 73 is threadedly connected to the side wall of the lead screw 72, and a cleaning brush is fixedly connected to the bottom end of the slide plate 73. The inner walls of the two sides of the protective cover 5 are fixedly connected with a limiting rod 74. The limiting rod 74 penetrates and is slidably connected to the side wall of one end of the slide plate 73. By setting the limiting rod 74, the slide plate 73 is prevented from rotating.
[0033] The collecting assembly 9 includes a collecting box 91, which is slidably connected to the inside of the storage slot 12. A cover plate 94 is rotatably connected to the opening of the collecting box 91. An arc rod 95 is symmetrically fixedly connected to the inner wall of one side of the collecting box 91. One end of each arc rod 95 is slidably connected to the side wall of the cover plate 94. A third spring 96 is symmetrically fixedly connected to the inner wall of the collecting box 91. One end of the third spring 96 is in contact with the bottom end of the cover plate 94. Each third spring 96 is sleeved on the corresponding arc rod 95. Under the action of its own gravity, the fragments cause the cover plate 94 to rotate and compress the third spring 96, and then the fragments will enter the inside of the collecting box 91. After the fragments enter the collecting box 91, the cover plate 94 is reset along the arc rod 95 under the elastic action of the third spring 96, so that the fragments are collected.
[0034] The outer wall of the collection box 91 is symmetrically fixedly connected with connecting rods 92, and the two connecting rods 92 are commonly fixedly connected with a pull plate 93. The connecting rods 92 and the pull plate 93 both pass through the through hole 13. The collection box 91 is taken out from the storage slot 12 along the through hole 13 through the pull plate 93, and the fragments in the collection box 91 are poured out, and finally put back into the storage slot 12 through the through hole 13 for subsequent debris collection.
[0035] In this embodiment, after the detection is completed, the second motor 71 is started, wherein the second motor 71 is a forward and reverse motor, and the second motor 71 rotates forward to drive the lead screw 72 to rotate. Under the limiting action of the limiting rod 74, the slide plate 73 is prevented from rotating along the lead screw 72 during its movement. When the slide plate 73 moves close to the second motor 71, the cleaning brush at the bottom of the slide plate 73 is used to clean the debris on the surface of the permeable brick 4. The cleaned debris will enter the collection box 91, and the debris will be covered under the action of its own gravity. The plate 94 rotates and compresses the third spring 96, and then the debris enters the collection box 91. After the debris enters the collection box 91, the cover plate 94 is reset along the arc rod 95 under the elastic action of the third spring 96, so that the debris is collected. Finally, after all the permeable bricks 4 are inspected, the collection box 91 is taken out from the storage slot 12 along the through hole 13 by pulling the plate 93, and the debris in the collection box 91 is poured out, and finally put back into the storage slot 12 through the through hole 13 to facilitate the subsequent collection of debris.
[0036] Working principle: First, multiple permeable bricks 4 are sent horizontally through the feeding hole 51 to the middle position of the inspection table 1, and then the hand 32 is turned forward, and the two-way screw 31 is driven to rotate by the rotation of the hand 32, so that the two sliders 33 threadedly connected to the side wall of the two-way screw 31 are close to each other along the slide groove 11 until the two U-shaped clamping plates 35 are in contact with the side walls of the multiple permeable bricks 4; after the permeable bricks 4 are clamped and fixed, the first motor 63 is started, and the first motor 63 is driven to rotate the shaft 64 and the cam 65 on the side wall of the shaft 64. During the rotation process, when the raised end of the cam 65 is in contact with the top plate After the cam 67 contacts the top plate 67, the top plate 67, the multiple slide bars 66, the bottom plate 69 and the detection head move upward, and the second spring 68 sleeved on the side wall of each slide bar 66 is compressed. When the raised end of the cam 65 is no longer in contact with the top plate 67, the top plate 67, the multiple slide bars 66 and the bottom plate 69 move downward under the elastic action of the multiple second springs 68, so that the multiple detection heads at the bottom end of the bottom plate 69 collide with the permeable brick 4, thereby performing strength testing. During the testing process, if the permeable brick 4 does not break, the quality is qualified. On the contrary, if the permeable brick 4 breaks, it means that the quality is unqualified.
[0037] After the detection is completed, the second motor 71 is started, wherein the second motor 71 is a forward and reverse motor. The second motor 71 rotates forward to drive the lead screw 72 to rotate. Under the limiting action of the limiting rod 74, the slide plate 73 is prevented from rotating along the lead screw 72 during the movement. When the slide plate 73 moves close to the second motor 71, the cleaning brush at the bottom of the slide plate 73 is used to clean the debris on the surface of the permeable brick 4. The cleaned debris will enter the collection box 91. Under the action of its own gravity, the cover plate 94 rotates and compresses the third spring 96. Then the debris will enter the collection box 91. After the debris enters the collection box 91, the cover plate 94 is reset along the arc rod 95 under the elastic action of the third spring 96, so as to collect the debris. Finally, after all the permeable bricks 4 are detected, the collection box 91 is taken out from the storage slot 12 along the through hole 13 by the pull plate 93, the debris in the collection box 91 is poured out, and finally put back into the storage slot 12 through the through hole 13 for subsequent debris collection.
