Description

Technical Field

[0001] This invention relates to the field of cement cover plate testing technology, specifically to a cement cover plate testing device based on new building materials. Background Technology

[0002] After production, cement product covers (such as trench covers, manhole covers, etc.) need to undergo multiple quality tests to ensure that their strength, durability, dimensional accuracy, etc. meet relevant standards. Currently, after the conventional cement product covers are produced, the load-bearing capacity of the sample needs to be tested using a pressure testing machine. Pressure is applied to the sample until it breaks, and the maximum load is recorded.

[0003] In the production process of cement cover plates, pressure strength testing is a crucial step in ensuring product quality. Traditional cement cover plate pressure testing devices typically use hydraulic or mechanical pressure application methods. After fixing the specimen with upper and lower clamps, pressure is applied until the specimen breaks to determine its compressive strength. However, after the test, cement debris easily remains on the surface of the lower clamp, which is inefficient to clean manually, and the residual debris may affect the accuracy of subsequent tests. Summary of the Invention

[0004] The purpose of this invention is to provide a cement cover plate testing device based on new building materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cement cover plate detection device based on new building materials, comprising... A pressure testing machine, used for pressure testing of cement product cover plates; The pressure testing machine consists of a controller and a testing device. The testing device consists of a column, a moving plate, a lower fixed plate, a screw, an upper clamping plate, a base, and a lower clamping plate. The base and the lower clamping plate are equipped with driven devices for cleaning debris from the top of the lower clamping plate. The column is equipped with a protective device to prevent debris from splashing.

[0006] Preferably, the column passes through the movable plate and the lower fixed plate, the column is fixedly connected to the lower fixed plate, the top of the lower fixed plate is fixed with a base, the top of the base is provided with a lower clamping plate, the screw passes through the movable plate and is threadedly connected to the movable plate, and the bottom of the screw is rotatably connected to the top of the upper clamping plate. By placing the cement cover plate to be tested on the top of the lower clamping plate, rotating the wheel at the top of the screw controls the screw to rotate, thereby controlling the upper clamping plate to move downward, so that the upper and lower clamping plates clamp the cement cover plate first. At this time, pressure can be applied to the cement cover plate by simply starting the device through the controller until the cement cover plate is crushed, thus completing the pressure test.

[0007] Preferably, the driven device includes a bracket fixed to the front of the base, a sleeve fixed on the bracket, the sleeve penetrating the bracket, a rotating sleeve rotatably mounted on the outer wall of the sleeve, and a sliding sleeve slidably mounted on the outer wall of the sleeve. Two sets of support rods are fixed to the bottom of the lower clamping plate. The rotating sleeve passes through one set of support rods and is slidably connected to the support rod. The sliding sleeve passes through the other set of support rods and is rotatably connected to the support rod. A vertical slider is slidably mounted on the bottom of the lower clamping plate. A horizontal slider is slidably mounted on the bottom of the vertical slider. A push rod is hinged to the bottom of the horizontal slider, and the push rod is located away from the horizontal slider. One end of the block is hinged to the inner wall of the base. A support spring is fixed to the bottom of the push rod. The end of the support spring away from the push rod is fixed to the inner wall of the base. Limiting components are provided at the bottom of the lower clamping plate and inside the base. When the lower clamping plate is not restricted, under the action of the support spring, the lower clamping plate can rotate at the position connected to the support rod, rotating sleeve and sliding sleeve, so that the lower clamping plate is tilted. The debris at the top of the lower clamping plate can slide down along the lower clamping plate to achieve cleaning and avoid the residue on the top of the lower clamping plate. This would prevent the bottom of the cement cover plate from being blocked by the residue when testing a new cement cover plate, which would affect the normal test results.

[0008] Preferably, the limiting component includes a boss, a vertical rod fixed to the bottom of the boss, the vertical rod passing through and slidably connected to the lower clamping plate, a return spring fixed to the bottom of the lower clamping plate, the end of the return spring away from the lower clamping plate being fixed to the vertical rod, a support rod hinged to the bottom of the vertical rod, the end of the support rod away from the vertical rod being hinged to a locking rod, the locking rod being slidably mounted on the bottom of the lower clamping plate, a limiting rod slidably mounted on the bottom of the lower clamping plate, a connecting spring fixed to the end of the limiting rod near the vertical rod, the end of the connecting spring away from the limiting rod being fixed to the lower clamping plate, a fixing block fixed to the side of the limiting rod near the locking rod, and a fixing rod fixed to the side of the locking rod, the fixing rod passing through... A contact block is inserted and slidably connected to it. A tension spring is fixed to the side of the contact block near the fixed rod, and the end of the tension spring away from the contact block is fixed to the side of the clamping rod. A triangular groove is formed on the side of the contact block near the vertical rod. A contact spring is fixed to the bottom of the lower clamping plate. Three sets of slots are formed on the inner wall of the base. When the cement cover to be tested is placed on the top of the lower clamping plate, the boss is pushed by the cement cover to move the vertical rod downward. The vertical rod can then push the clamping rod to move away from the vertical rod through the support rod, so that the clamping rod is inserted into the slot. During this process, the inclined surface of the contact block abuts against the inclined surface of the fixed block, causing the contact block to move towards the clamping rod. This will not affect the normal insertion of the locking rod into the slot. Together with the limiting rod, it forms a double lock when inserted into the other two sets of slots. When most of the cement cover plate after inspection is removed, the boss is no longer under sufficient pressure. Under the action of the return spring, the vertical rod, carrying the boss, returns to its original position. At this time, the vertical rod can pull the locking rod towards the side closer to the vertical rod via the support rod, causing the locking rod to exit from the slot. Simultaneously, the locking rod moves along with the fixing rod and the contact block. The vertical surface of the contact block abuts against the vertical surface of the fixing block, allowing the contact block to push the fixing block and the limiting rod to move together, causing the limiting rod to exit from the slot, thus releasing the restriction on the lower clamping plate. At this point, the lower clamping plate can fold over as the contact block moves... During the process, after the contact spring is inserted into the triangular groove, as the contact block continues to move, the contact spring is squeezed and folded, allowing it to move towards the side closer to the clamping rod through the contact block. This separates the contact block from the fixing block. At this time, under the action of the connecting spring, the limiting rod can move the fixing block away from the vertical rod. After cleaning, when the staff manually presses the lower clamping plate to reset, the inclined surface of the limiting rod first contacts the base, causing the limiting rod to move slightly towards the vertical rod. When the limiting rod moves to the position of the clamping groove, it can be inserted into the clamping groove under the action of the connecting spring to restrict the lower clamping plate, avoiding affecting the next normal inspection of the cement cover plate, effectively improving the overall inspection efficiency.

[0009] Preferably, the protective device includes a mounting hoop, which is fixed to the outer wall of the column by bolts. A baffle is hinged to the mounting hoop, and a magnet is fixed to the side of the baffle near the base. By using bolts to install the mounting hoop and the baffle to the column, during normal testing, the baffle can effectively prevent the fragments of stone from splashing and injuring the staff by blocking the front. The baffle is temporarily fixed by the magnet adhering to the column, and the staff can easily open or close the baffle. The overall operation is convenient.

[0010] Preferably, the lower clamping plate and the sleeve are provided with an auxiliary device, which includes a piston block connected to the inner wall of the sleeve. A connecting rod is fixed to the right side of the piston block, and the end of the connecting rod away from the piston block is fixed to the side of the sliding sleeve away from the center of the sleeve. A flexible hose is connected to and fixed to the left side of the sleeve, and the end of the flexible hose away from the sleeve is connected to and fixed to a nozzle. The nozzle is fixed to the back of the lower clamping plate. A vibration spring is fixed to the outer wall of the rotating sleeve, and the end of the vibration spring away from the rotating sleeve is fixed to a support rod sliding on the outer wall of the rotating sleeve. A mating protrusion is fixed to the side of the support rod sliding on the outer wall of the rotating sleeve away from the vibration spring. A fixing protrusion is fixed to the outer wall of the sleeve. The nozzle outlet section is designed as a tapered-expanding flow channel, utilizing Bernoulli's principle to enhance the airflow. The high flow rate effectively enhances the cleaning force. When the lower clamping plate is released from its restraints and flips over, it moves along with two sets of support rods. One set of support rods rotates along with the rotating sleeve. At this time, the support rods rotate along with the mating protrusion. When the mating protrusion contacts the fixed protrusion, the lower clamping plate can be moved. With the help of the vibration spring, the support rods move back and forth with the lower clamping plate to create a shaking motion, which can effectively shake off the residue attached to the top of the lower clamping plate, improving the cleaning effect without much manual intervention. While the support rods move back and forth, the other set of support rods moves along with the sliding sleeve. The sliding sleeve pushes the piston block to move back and forth inside the sleeve through the connecting rod, realizing the back and forth blowing of the nozzle through the hose. When the nozzle blows, the residue attached to the top of the lower clamping plate can be blown away, further improving the cleaning effect.

[0011] Compared with the prior art, the present invention provides a cement cover plate detection device based on new building materials, which has the following beneficial effects: 1. This cement cover plate detection device based on new building materials utilizes the elastic potential energy of the support spring when it is released to drive the lower clamping plate to rotate. During this process, the gap between the support rod and the rotating sleeve will form a periodic mechanical collision, thereby generating high-frequency micro-amplitude vibration. This vibration, in conjunction with the airflow pulses ejected from the nozzle, forms a synergistic cleaning mechanism of mechanical vibration and airflow purging. It can not only effectively remove conventional debris, but also has an excellent cleaning effect on highly adhesive, damp, and compacted residues, significantly improving the self-cleaning ability of the equipment.

[0012] 2. This cement cover plate testing device based on new building materials, through the setting of a limiting component, after cleaning, when the staff manually presses the lower clamp plate to reset, the inclined surface of the limiting rod first contacts the base, causing the limiting rod to move slightly to one side of the vertical rod. When the limiting rod moves to the position of the slot, it can be inserted into the slot under the action of the connecting spring to restrict the lower clamp plate, so as to avoid affecting the normal testing of the cement cover plate next time, effectively improving the overall testing efficiency.

[0013] 3. This cement cover plate testing device based on new building materials, through the protective device, can effectively prevent the fragments of stone from splashing and injuring the staff during normal testing by blocking the front of the cover plate. The cover plate is temporarily fixed by magnetic adsorption to the column, and the staff can easily open or close the cover plate. The overall operation is convenient. Attached Figure Description

[0016] like Figures 1-9 As shown, the present invention provides a technical solution: a cement cover plate testing device based on new building materials, comprising a pressure testing machine, which consists of a controller 1 and a testing device 2. The testing device 2 includes a column 21, which passes through a movable plate 22 and a lower fixed plate 23. The column 21 is fixedly connected to the lower fixed plate 23. A base 26 is fixed to the top of the lower fixed plate 23. A lower clamping plate 27 is provided on the top of the base 26. A screw 24 passes through the movable plate 22 and is threadedly connected to the movable plate 22. The bottom of the screw 24 is rotatably connected to the top of the upper clamping plate 25. By placing the cement cover plate to be tested on top of the lower clamping plate 27, rotating the wheel at the top of the screw 24 controls the screw 24 to rotate, thereby controlling the upper clamping plate 25 to move downward, so that the upper clamping plate 25 and the lower clamping plate 27 clamp the cement cover plate. At this time, the device can be started by the controller 1 to apply pressure to the cement cover plate until the cement cover plate is crushed, thus completing the pressure test. The base 26 and the lower clamping plate 27 are equipped with a driven device 3 for cleaning the debris on the top of the lower clamping plate 27, and the column 21 is equipped with a protective device 4 to prevent debris from splashing.

[0017] The driven device 3 includes a bracket 31, which is fixed to the front of the base 26. A sleeve 32 is fixed on the bracket 31 and passes through the bracket 31. A rotating sleeve 33 is rotatably mounted on the outer wall of the sleeve 32, and a sliding sleeve 34 is slidably mounted on the outer wall of the sleeve 32. Two sets of support rods 35 are fixed to the bottom of the lower clamping plate 27. The rotating sleeve 33 passes through one set of support rods 35 and is slidably connected to the support rod 35. The sliding sleeve 34 passes through the other set of support rods 35 and is rotatably connected to the support rod 35. A vertical slider 36 is slidably mounted on the bottom of the lower clamping plate 27. A horizontal slider 37 is slidably mounted on the bottom of the vertical slider 36. A push rod 38 is hinged to the bottom of the horizontal slider 37. The end of the push rod 38 away from the horizontal slider 37 is... Hinged to the inner wall of the base 26, the bottom of the push rod 38 is fixed with a support spring 39. The end of the support spring 39 away from the push rod 38 is fixed to the inner wall of the base 26. The bottom of the lower clamping plate 27 and the inside of the base 26 are provided with a limit component 5. When the lower clamping plate 27 is not restricted, under the action of the support spring 39, the lower clamping plate 27 can rotate at the position connected to the support rod 35, the rotating sleeve 33 and the sliding sleeve 34, so that the lower clamping plate 27 is tilted. The debris at the top of the lower clamping plate 27 can slide down along the lower clamping plate 27 to achieve cleaning. This avoids the residue on the top of the lower clamping plate 27, which would cause the bottom of the cement cover to be blocked by the residue when testing the new cement cover, affecting the normal test results.

[0018] In addition, the limiting component 5 includes a boss 51, with a vertical rod 52 fixed to the bottom of the boss 51. The vertical rod 52 passes through the lower clamping plate 27 and is slidably connected to the lower clamping plate 27. A return spring 513 is fixed to the bottom of the lower clamping plate 27. The end of the return spring 513 away from the lower clamping plate 27 is fixed to the vertical rod 52. A support rod 53 is hinged to the bottom of the vertical rod 52. The end of the support rod 53 away from the vertical rod 52 is hinged to the locking rod 54. The locking rod 54 is slidably installed at the bottom of the lower clamping plate 27. A limiting rod 55 is slidably installed at the bottom of the lower clamping plate 27. A connecting spring 514 is fixed to the end of the limiting rod 55 near the vertical rod 52. The end of the connecting spring 514 away from the limiting rod 55 is fixed to the lower clamping plate 27. A fixing block 56 is fixed to the side of the limiting rod 55 near the locking rod 54. A fixing rod 57 is fixed to the side of the clamping rod 54. The fixing rod 57 passes through the abutment block 58 and is slidably connected to the abutment block 58. A tension spring 59 is fixed to the side of the abutment block 58 near the fixing rod 57. The end of the tension spring 59 away from the abutment block 58 is fixed to the side of the clamping rod 54. A triangular groove 510 is opened on the side of the abutment block 58 near the vertical rod 52. An abutment spring 511 is fixed to the bottom of the lower clamping plate 27. Three sets of slots 512 are opened on the inner wall of the base 26. When the cement cover to be tested is placed on the top of the lower clamping plate 27, the boss 51 is abutted and the vertical rod 52 moves downward due to the gravity of the cement cover. The vertical rod 52 can then push the clamping rod 54 to the side away from the vertical rod 52 through the support rod 53, so that the clamping rod 54 is inserted into the slot 510. Within 12, during this process, the inclined surface of the contact block 58 abuts against the inclined surface of the fixing block 56, causing the contact block 58 to move towards the side closer to the locking rod 54. This prevents the locking rod 54 from being properly inserted into the slot 512. Combined with the limit rod 55 inserting into the other two sets of slots 512, a double locking is formed. When most of the cement cover plate after inspection is removed, the boss 51 no longer experiences sufficient pressure. Under the action of the return spring 513, the vertical rod 52 moves the boss 51 upwards to reset. At this time, the vertical rod 52 can pull the locking rod 54 towards the side closer to the vertical rod 52 via the support rod 53, causing the locking rod 54 to exit from the slot 512. Simultaneously, the locking rod 54 moves together with the fixing rod 57 and the contact block 58. The vertical surface of the contact block 58 and the fixed block 56... The vertical surfaces abut against each other, allowing the abutting block 58 to push the fixing block 56 and move the limiting rod 55 together, causing the limiting rod 55 to disengage from the slot 512 and releasing the restriction on the lower clamping plate 27. At this point, the lower clamping plate 27 can fold over. During the movement of the abutting block 58, when the abutting spring 511 is inserted into the triangular groove 510, as the abutting block 58 continues to move, the abutting spring 511 is squeezed and folded over, allowing the abutting block 58 to move towards the side closer to the clamping rod 54, thus separating the abutting block 58 from the fixing block 56. At this time, under the action of the connecting spring 514, the limiting rod 55 can move the fixing block 56 away from the vertical rod 52. After cleaning, the worker can manually press the lower clamping plate 27 to reset.The inclined surface of the limiting rod 55 first abuts against the base 26, causing the limiting rod 55 to move slightly towards the side of the vertical rod 52. When the limiting rod 55 moves to the position of the slot 512, it can be inserted into the slot 512 under the action of the connecting spring 514 to restrict the lower clamping plate 27, avoiding interference with the next normal inspection of the cement cover plate, and effectively improving the overall inspection efficiency.

[0019] It is worth noting that in this embodiment, the protective device 4 includes a mounting hoop 41, which is fixed to the outer wall of the column 21 by bolts. A baffle 42 is hinged to the mounting hoop 41, and a magnet 43 is fixed to the side of the baffle 42 near the base 26. By using bolts to install the mounting hoop 41 and the baffle 42 to the column 21, during normal testing, the baffle 42 can effectively prevent the fragments from splashing and injuring the staff. The baffle 42 is temporarily fixed by the magnet 43 adsorbing onto the column 21, making it convenient for the staff to open or close the baffle 42. The overall operation is convenient.

[0020] An auxiliary device 6 is provided on the lower clamping plate 27 and the sleeve 32. The auxiliary device 6 includes a piston block 61, which is connected to the inner wall of the sleeve 32. A connecting rod 62 is fixed to the right side of the piston block 61. The end of the connecting rod 62 away from the piston block 61 is fixed to the side of the sliding sleeve 34 away from the center of the sleeve 32. A flexible hose 63 is connected to and fixed to the left side of the sleeve 32. The end of the flexible hose 63 away from the sleeve 32 is connected to and fixed to a nozzle 64. The nozzle 64 is fixed to the back of the lower clamping plate 27. A vibration spring 65 is fixed to the outer wall of the rotating sleeve 33. The end of the vibration spring 65 away from the rotating sleeve 33 is fixed to a support rod 35 sliding on the outer wall of the rotating sleeve 33. A mating protrusion 66 is fixed to the side of the support rod 35 sliding on the outer wall of the rotating sleeve 33 away from the vibration spring 65. A fixing protrusion 67 is fixed to the outer wall of the sleeve 32. The outlet section of the nozzle 64 is designed as a tapered-expanding flow channel, which utilizes Bernoulli's principle to increase the airflow velocity and effectively... To enhance the cleaning force, when the lower clamping plate 27 is released from its restraints and folds over, the lower clamping plate 27 moves together with two sets of support rods 35. One set of support rods 35 rotates together with the rotating sleeve 33. At this time, the support rods 35 rotate with the mating protrusion 66. When the mating protrusion 66 abuts against the fixed protrusion 67, the lower clamping plate 27 can be moved. With the help of the vibration spring 65, the support rods 35 move back and forth with the lower clamping plate 27 to achieve vibration, which can effectively shake off the residue attached to the top of the lower clamping plate 27, improving the cleaning effect without much manual intervention. When the support rods 35 move back and forth, the other set of support rods 35 moves together with the sliding sleeve 34. The sliding sleeve 34 pushes the piston block 61 to move back and forth in the sleeve 32 through the connecting rod 62, so that the nozzle 64 can be controlled to blow back and forth through the hose 63. When the nozzle 64 blows, the residue attached to the top of the lower clamping plate 27 can be blown away, further improving the cleaning effect.

[0021] During testing, the baffle 42 is manually pulled open, and the cement cover to be tested is placed on top of the lower clamping plate 27. At this time, under the gravity of the cement cover, the protrusion 51 is pushed and the vertical rod 52 moves downward. The vertical rod 52 can then push the locking rod 54 to the side away from the vertical rod 52 through the support rod 53, so that the locking rod 54 is inserted into the locking slot 512. During this process, the inclined surface of the contact block 58 abuts against the inclined surface of the fixing block 56, so that the contact block 58 moves closer to the locking rod 54, thus not affecting the normal insertion of the locking rod 54 into the locking slot 512. Together with the limiting rod 55, it is inserted into the other two sets of locking slots 512 to form a double lock.

[0022] The operator manually rotates the wheel at the top of the screw 24 to control the screw 24 to rotate, thereby controlling the upper clamping plate 25 to move downwards. This causes the upper clamping plate 25 and the lower clamping plate 27 to clamp the cement cover plate and close the baffle 42. At this point, the device can be started by the controller 1 to apply pressure to the cement cover plate until it is crushed, thus completing the pressure test.

[0023] After the test is completed, observe and record the values ​​on controller 1. After recording, open baffle 42, place a collection box on top of the lower fixed plate 23, and remove the cement cover plate. At this time, the boss 51 is no longer under sufficient pressure. Under the action of the return spring 513, the vertical rod 52 moves the boss 51 upward to reset. At this time, the vertical rod 52 can pull the locking rod 54 to the side closer to the vertical rod 52 through the support rod 53, so that the locking rod 54 is removed from the slot 512. At the same time, the locking rod 54 moves together with the fixed rod 57 and the contact block 58. The vertical surface of the contact block 58 is aligned with the vertical surface of the fixed block 56. The contact blocks 58 push the fixed block 56 and move the limiting rod 55 together, causing the limiting rod 55 to exit from the slot 512, thereby releasing the restriction on the lower clamping plate 27. During the movement of the contact block 58, when the contact spring 511 is inserted into the triangular groove 510, as the contact block 58 continues to move, the contact spring 511 is squeezed and folded, so that it can move towards the side closer to the locking rod 54 through the contact block 58, so that the contact block 58 is separated from the fixed block 56. At this time, under the action of the connecting spring 514, the limiting rod 55 can move away from the vertical rod 52 along with the fixed block 56.

[0024] When the lower clamping plate 27 is not restricted, under the action of the support spring 39, the lower clamping plate 27 can rotate at the position connected to the support rod 35, the rotating sleeve 33, and the sliding sleeve 34, so that the lower clamping plate 27 is tilted. The debris at the top of the lower clamping plate 27 can slide down along the lower clamping plate 27 to achieve cleaning. During this process, the lower clamping plate 27 moves together with the two sets of support rods 35, and one set of support rods 35 rotates together with the rotating sleeve 33. At this time, the support rods 35 rotate with the mating protrusion 66. When the mating protrusion 66 abuts against the fixed protrusion 67, the movement of the lower clamping plate 27 can be controlled. In conjunction with the vibration spring 65, the control rod 35 moves back and forth with the lower clamping plate 27 to create vibration, which can effectively shake off the residue attached to the top of the lower clamping plate 27, improving the cleaning effect without much manual intervention. When the support rod 35 moves back and forth, another set of support rods 35 moves together with the sliding sleeve 34. The sliding sleeve 34 pushes the piston block 61 to move back and forth in the sleeve 32 through the connecting rod 62, so that the nozzle 64 can be controlled by the hose 63 to blow back and forth. When the nozzle 64 blows, the residue attached to the top of the lower clamping plate 27 can be blown away, further improving the cleaning effect.

[0025] After cleaning, when the staff manually presses the lower clamp 27 to reset, the inclined surface of the limiting rod 55 first contacts the base 26, causing the limiting rod 55 to move slightly to one side of the vertical rod 52. When the limiting rod 55 moves to the position of the slot 512, it can be inserted into the slot 512 under the action of the connecting spring 514 to restrict the lower clamp 27, so as to avoid affecting the next normal inspection of the cement cover plate, effectively improving the overall inspection efficiency and completing a single inspection operation.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
