Description

Technical Field

[0001] This application relates to the field of concrete equipment technology, and in particular to a concrete pressure testing machine with a protective device. Background Technology

[0002] With the improvement of construction technology, the country is accelerating the construction of infrastructure projects, and the application of concrete in the construction market is increasing. At the same time, the requirements for project quality and environmental protection are becoming more and more stringent. In construction projects, it is usually necessary to test the performance of concrete regularly. The method is to cast a batch of cubic concrete test blocks of specified dimensions, and then use a concrete compression testing machine to compress these concrete test blocks until they break, and obtain various data values.

[0003] Existing concrete pressure testing machines mainly consist of a base installed on the ground, on which test components and a control cabinet are mounted. The test components include four vertical columns mounted on the base, with mounting seats installed on the columns. The mounting seats are internally threaded with studs, and hydraulic plates are installed at the lower ends of the studs. The control cabinet contains a hydraulic control system and a testing system. During testing, the worker first places the concrete specimen on the base, then rotates the studs to bring the hydraulic plate closer to the concrete specimen, and finally applies pressure to the concrete specimen continuously through the hydraulic plate. The pressure value that the concrete specimen can withstand is obtained from the testing system.

[0004] Regarding the aforementioned technologies, the inventors believe that during the continuous pressure application to concrete, concrete blocks will break and splash out of the testing machine body through the gaps between the columns, thereby reducing the safety of concrete pressure testing and easily injuring the operators in front of the concrete pressure testing machine, which is obviously insufficient. Utility Model Content

[0005] To improve the safety of concrete pressure testing, this application provides a concrete pressure testing machine with protective devices.

[0006] The concrete pressure testing machine with a protective device provided in this application adopts the following technical solution:

[0007] A concrete pressure testing machine with a protective device includes a base, on which a test assembly and a control cabinet are mounted. A protective shell is fixedly mounted on the base. The protective shell includes a placement plate and a protective frame. The protective frame is located on the outer periphery of the placement plate. An opening is formed at the top of the protective frame to allow the hydraulic plate in the test assembly to pass through. A protective door is hinged to the protective frame.

[0008] By adopting the above technical solution, during the test, the worker opens the protective door and places the concrete test block on the placement plate. After the test preparation is completed, the worker closes the protective door and starts the test assembly to conduct the test. Under the enclosure of the protective frame and the protective door, the concrete test block is in a closed test area, thereby blocking the path of concrete fragments splashing to the outside of the machine and improving the safety of the concrete pressure test.

[0009] Optionally, a buffer assembly is provided inside the protective shell. The buffer assembly includes a buffer pad disposed on the inner peripheral sidewall of the protective door and the protective frame. Buffer airbags are disposed on opposite sides of the protective frame. The buffer airbags are disposed between the protective frame and the buffer pads. The buffer pads are disposed on the surface of the buffer airbags facing away from the protective frame. An inflation assembly for supplying gas to the buffer airbags is provided inside the protective shell.

[0010] By adopting the above technical solution, before the test begins, the inflation component inflates the buffer airbag. As the buffer airbag inflates and expands, when the concrete specimen breaks inside the protective shell, the buffer pad first contacts the splashed fragments to reduce the impact. At the same time, the inflated buffer airbag further absorbs the impact force, effectively dispersing and dissolving the impact force. The buffer component reduces the impact force when concrete fragments break and splash, thereby reducing the damage to the protective shell and improving the safety of the concrete test and the service life of the protective shell.

[0011] Optionally, the placement plate has a groove, and the inflation assembly includes an air supply bladder disposed inside the groove. The air supply bladder stores gas, and a support plate is disposed on the upper surface of the air supply bladder. The support plate is slidably connected to the groove. Each buffer bladder is connected to the air supply bladder through an air tube. Both the buffer bladder and the air supply bladder are made of elastic material. When the air supply bladder is not compressed, the surface of the support plate is flush with the surface of the placement plate. A cleaning assembly is disposed inside the protective shell.

[0012] By adopting the above technical solution, when the concrete test block is placed on the bearing plate, the weight of the test block pushes the bearing plate downward, and the bearing plate compresses the air supply bladder. The gas in the air supply bladder is inflated into the buffer bladder through the air tube, and the buffer bladder expands to provide cushioning for the test. After the test, the cleaning component sweeps the fragments out of the bearing plate, the weight on the bearing plate disappears, and the buffer bladder and air supply bladder recover their deformation under their own elasticity. The gas in the buffer bladder flows back into the air supply bladder through the air tube, providing conditions for the buffer preparation work of the next test. The inflation component converts the weight of the concrete test block into the power source of gas flow, eliminating the need for workers to enter the protective shell for additional restart operations, simplifying the test process and improving the convenience of worker operation.

[0013] Optionally, the cleaning assembly includes electric guide rails disposed on opposite sides of the top wall inside the protective frame, a movable plate slidably connected to the two electric guide rails, a receiving groove provided on the movable plate, a sweeping plate slidably connected inside the receiving groove, a retaining spring disposed inside the receiving groove, one end of the retaining spring being disposed on the inner side wall of the receiving groove, and the other end being disposed on the sweeping plate, the elastic force of the retaining spring driving the sweeping plate to abut against the surface of the support plate.

[0014] By adopting the above technical solution, after the test, the workers opened the protective door and then started the electric guide rail. The electric guide rail drove the moving plate to slide along the inner top wall of the protective frame. Under the action of the spring force of the clamping spring, the cleaning plate on the moving plate always kept in close contact with the surface of the bearing plate. As the moving plate slid, the cleaning plate quickly swept the concrete debris remaining on the bearing plate to the outside of the protective shell. In this way, the concrete debris was automatically cleaned, avoiding the safety hazards and inconvenience caused by manual cleaning. At the same time, the clamping spring could adapt to the height change of the bearing plate, ensuring that the cleaning plate and the bearing plate were in full contact, effectively improving the cleaning effect.

[0015] Optionally, a collection box is provided on the outer surface of the base, and the opening of the collection box is located below the protective door.

[0016] By adopting the above technical solution, when the cleaning component sweeps the concrete debris out of the protective shell, the debris falls directly into the collection box, reducing the need for manual bending over to pick it up or additional transfer operations, thereby reducing the labor intensity during the cleaning process.

[0017] Optionally, the outer wall of the support plate away from the protective door and the inner wall of the protective frame enclose a non-working area. A guide slope is provided on the side of the support plate near the non-working area, and a sliding slope is provided on the cleaning plate that slides with the guide slope. The sliding slope and the guide slope have the same inclination.

[0018] By adopting the above technical solution, when the cleaning plate is transferred from the non-working area to the surface of the carrier plate, the sliding ramp can smoothly transition along the guide ramp, reducing the phenomenon of the cleaning plate getting stuck due to height difference or the elasticity of the clamping spring, ensuring that the cleaning plate smoothly transitions to the surface of the carrier plate, and ensuring the normal operation of the cleaning component.

[0019] Optionally, guide grooves are provided on the inner sidewalls of the grooves, and guide blocks that slide in cooperation with the guide grooves are provided on the opposite sides of the bearing plate.

[0020] By adopting the above technical solution, the guide groove and guide block effectively limit the displacement of the bearing plate in the direction other than vertical, reduce the shaking or displacement of the bearing plate when the concrete test block is placed, and thus make the air supply bag uniformly stressed.

[0021] Optionally, a corrugated cover is provided on the inner sidewall of the groove, and the end of the corrugated cover away from the groove is disposed on the guide block.

[0022] By adopting the above technical solution, when the bearing plate slides along the guide groove under the drive of the guide block, the corrugated cover can extend and retract synchronously with the guide block, effectively reducing the possibility of concrete fragments, dust and other impurities entering the groove, thereby ensuring the smooth sliding of the bearing plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a protective shell and buffer components, when the concrete test block collapses inside the protective shell, the buffer pad and the inflated buffer airbag effectively reduce the impact force when the concrete fragments collapse and splash, thereby reducing the damage to the protective shell. At the same time, under the enclosure of the protective frame and protective door, the concrete test block is in a closed test area, thereby blocking the path of concrete fragments splashing to the outside of the machine and improving the safety of the concrete pressure test.

[0025] 2. This application uses an inflation component to convert the weight of the concrete test block into a power source for gas flow, eliminating the need for workers to enter the protective shell for additional restart operations, thus simplifying the testing process and improving the convenience of worker operation.

[0026] 3. This application sets up a cleaning component, which realizes automatic cleaning of concrete fragments, avoiding the safety hazards and inconvenience caused by manual cleaning. At the same time, the clamping spring can adapt to the height change of the support plate, ensuring full contact between the cleaning plate and the support plate, effectively improving the cleaning effect.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a concrete pressure testing machine with a protective device.

[0034] Reference Figure 1 A concrete pressure testing machine with a protective device includes a base 1, on which a test component 01 and a control cabinet 02 are installed. The test component 01, the control cabinet 02, and the operation of performing pressure tests on concrete test blocks are all existing technologies and will not be described in detail here.

[0035] Reference Figure 1 and Figure 2 A protective shell 2 is provided on the base 1. The protective shell 2 includes a placement plate 21 and a protective frame 22. The placement plate 21 is fixedly connected to the base 1, and the protective frame 22 is fixedly connected to the outer periphery of the placement plate 21. An opening 221 is provided on the top of the protective frame 22 for the hydraulic plate in the test assembly 01 to pass through. The size of the opening 221 is larger than the size of the hydraulic plate. A protective door 23 is hinged to the outer surface of the protective frame 22.

[0036] Reference Figure 2 and Figure 3 The protective shell 2 is equipped with a buffer assembly 3. The buffer assembly 3 includes a buffer pad 31 fixedly connected to the inner peripheral side wall of the protective door 23 and the protective frame 22. The buffer pad 31 is made of flexible material. Buffer airbags 32 are fixedly connected to opposite sides of the protective frame 22. The buffer airbags 32 are located between the inner side wall of the protective frame 22 and the buffer pad 31. The surface of the buffer airbags 32 facing away from the protective frame 22 is connected to the buffer pad 31. An inflation assembly 4 is provided inside the protective shell 2 to supply gas to the buffer airbags 32.

[0037] Reference Figure 2 and Figure 3The placement plate 21 has a groove 5. The air supply component includes an air supply bladder 41 fixedly connected to the bottom wall of the groove 5. Both the air supply bladder 41 and the buffer bladder 32 are made of elastic material. The air supply bladder 41 stores gas. The air supply bladder 41 is fixedly connected to a support plate 42 away from the surface of the placement plate 21. The support plate 42 is slidably connected inside the groove 5. Each buffer bladder 32 is connected to the air supply bladder 41 through an air tube 43. When the air supply bladder 41 is not compressed, the air supply bladder 41 is inflated and expanded, and the buffer bladder 32 is in a deflated state. The surface of the support plate 42 is flush with the surface of the placement plate 21.

[0038] Before the test, the worker opened the protective door 23 and placed the concrete test block on the bearing plate 42. The weight of the test block pushed the bearing plate 42 downward, and the bearing plate 42 squeezed the air supply bladder 41. The gas in the air supply bladder 41 was filled into the buffer bladder 32 through the air pipe 43. The buffer bladder 32 was inflated. Then the worker closed the protective door 23 and started the test assembly 01 to conduct the test.

[0039] When the concrete test block breaks inside the protective shell 2, the buffer pad 31 and the inflated buffer airbag 32 effectively reduce the impact force when the concrete fragments fly out, thereby reducing the damage to the protective shell 2. At the same time, under the enclosure of the protective frame 22 and the protective door 23, the concrete test block is in a closed test area, thereby blocking the path of concrete fragments flying to the outside of the machine and improving the safety of the concrete pressure test.

[0040] Reference Figure 2 and Figure 3 The groove 5 has guide grooves 51 on its inner sidewalls facing each other in the vertical direction. The bearing plate 42 has guide blocks 421 that slide with the guide grooves 51 on its opposite sides. The guide grooves 51 and guide blocks 421 restrict the displacement of the bearing plate 42 in the vertical direction, thereby reducing the shaking or displacement of the bearing plate 42 when the concrete test block is placed.

[0041] Reference Figure 2 and Figure 3 A corrugated cover 52 is fixedly connected to the inner wall of the groove 5 away from the air supply bladder 41. The corrugated cover 52 is a telescopic cover. The end of the corrugated cover 52 away from the groove 5 is fixedly connected to the guide block 421. When the bearing plate 42 slides along the guide groove 51 under the drive of the guide block 421, the corrugated cover 52 expands and contracts synchronously with the guide block 421, which effectively reduces the possibility of the concrete test block entering the groove 5 when it breaks, thereby ensuring the smooth sliding of the bearing plate 42.

[0042] Reference Figure 2 and Figure 4The protective shell 2 is equipped with a cleaning component 6. The cleaning component 6 includes electric guide rails 61 fixedly connected to opposite sides of the top wall inside the protective frame 22. The electric guide rails 61 are parallel to the length direction of the protective shell 2. A moving plate 62 is slidably connected to the two electric guide rails 61. The moving plate 62 has a receiving groove 621 on its surface facing the support plate 42. The receiving groove 621 is vertically arranged. A sweeping plate 63 is slidably connected inside the receiving groove 621. A retaining spring 64 is provided inside the receiving groove 621. One end of the retaining spring 64 is fixedly connected to the inner side wall of the receiving groove 621 away from the support plate 42, and the other end is fixedly connected to the sweeping plate 63. The elastic force of the retaining spring 64 drives the sweeping plate 63 to abut against the surface of the support plate 42.

[0043] Reference Figure 2 and Figure 4 The outer wall of the bearing plate 42 away from the protective door 23 and the inner wall of the protective frame 22 enclose a non-working area 7. A guide slope 422 is provided on the side of the bearing plate 42 near the non-working area 7. A sliding slope 631 is provided on the cleaning plate 63, which slides with the guide slope 422. The sliding slope 631 and the guide slope 422 have the same inclination. When the cleaning plate 63 is in a non-working state, the moving plate 62 and the cleaning plate 63 stay inside the non-working area 7.

[0044] Reference Figure 1 and Figure 4 A collection box 8 is fixedly connected to the outer surface of the base 1, and the opening 221 of the collection box 8 is located below the protective door 23.

[0045] After the test, the worker opened the protective door 23 and then started the electric guide rail 61. The electric guide rail 61 drove the moving plate 62 to slide along the length of the bearing plate 42. With the smooth transition between the sliding inclined surface 631 and the guide inclined surface 422, the moving plate 62 drove the cleaning plate 63 to move to the surface of the bearing plate 42. At this time, the cleaning plate 63 was always in close contact with the surface of the bearing plate 42 under the elastic force of the clamping spring 64. As the moving plate 62 slid, the cleaning plate 63 quickly swept the concrete debris remaining on the bearing plate 42 to the outside of the protective shell 2. The concrete debris fell into the collection box 8. In this way, the concrete debris was automatically cleaned, avoiding the safety hazards and inconvenience caused by manual cleaning. At the same time, the clamping spring 64 could adapt to the height change of the bearing plate 42 to ensure that the cleaning plate 63 and the bearing plate 42 were in full contact, effectively improving the cleaning effect.

[0046] After the concrete debris is cleaned up, the weight on the bearing plate 42 disappears, and the buffer airbag 32 and the air supply airbag 41 recover their deformation under their own elasticity. The gas in the buffer airbag 32 flows back to the air supply airbag 41 through the air pipe 43, providing conditions for the buffer preparation work of the next test.

[0047] The implementation principle of a concrete pressure testing machine with a protective device in this application embodiment is as follows: Before the test, the worker opens the protective door 23 and places the concrete test block on the bearing plate 42. The weight of the test block pushes the bearing plate 42 downward, and the bearing plate 42 squeezes the air supply bladder 41. The gas in the air supply bladder 41 is filled into the buffer bladder 32 through the air pipe 43. The buffer bladder 32 is inflated. Then the worker closes the protective door 23 and starts the test assembly 01 to carry out the test.

[0048] When the concrete test block breaks inside the protective shell 2, the buffer pad 31 and the inflated buffer airbag 32 effectively reduce the impact force when the concrete fragments fly out, thereby reducing the damage to the protective shell 2. At the same time, under the enclosure of the protective frame 22 and the protective door 23, the concrete test block is in a closed test area, thereby blocking the path of concrete fragments flying to the outside of the machine and improving the safety of the concrete pressure test.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
