Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and in particular to a skid-mounted container concrete sample intelligent curing and compression testing system. Background Art

[0002] During highway construction, concrete needs to be cured and sampled in a curing room maintained at a constant temperature and humidity after pouring. Only samples that meet mechanical performance standards can be used. With the continuous introduction of advanced equipment and technology in the highway engineering industry, project quality has been significantly improved and construction progress has been accelerated. Therefore, the efficiency of curing and testing must be matched with the on-site construction schedule to ensure the timeliness of testing and provide timely guidance for on-site construction.

[0003] Traditional concrete curing and inspection systems are centrally located at a fixed location, so the system cannot be moved with the construction site. There is a possibility that the system is far from the construction site, resulting in increased transportation costs for concrete blocks and slowing down the highway construction schedule.

[0004] In order to solve the above problems, there are also some cases of temporarily building concrete curing rooms at the construction site. However, for highway projects, the construction of standard concrete curing rooms on site and the subsequent demolition require a lot of time and cost, and will generate a lot of construction waste. The generation and treatment of construction waste will increase carbon dioxide emissions, which is not friendly to the environment. At the same time, the construction site of highway projects changes quickly, and the temporary concrete curing rooms built on site are actually put into use for a short time.

[0048] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. In addition, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] See also Figures 1 to 3 As shown, the present invention provides a skid-mounted container concrete sample intelligent curing and compression testing system, comprising a plurality of integrated boxes, wherein the integrated boxes include a main box 1 and at least one curing box 2, and a communication port is provided between the main box 1 and the curing box 2;

[0050] The main box body 1 is provided with an entry and exit area 11, a detection area 12 and a central control operation area 13 in sequence in the direction away from the connecting port, and a storage entry area 14 is provided on the side of the entry and exit area 11;

[0051] A curing area 21 is provided in the curing box 2;

[0052] A movable stacker 8 is provided between the detection area 12 and the maintenance area 21. The stacker 8 is provided with an intermediate storage rack 81 for placing samples and a pick-and-place mechanism 82 for taking and placing samples. The samples can be transferred between the intermediate storage rack 81 and the storage area 14, the maintenance area 21 and the detection area 12 through the pick-and-place mechanism 82.

[0053] In the present invention, on the one hand, the various functional areas and related devices of the concrete curing and inspection system are pre-integrated into several integrated boxes. Specifically, the functional areas and related devices such as the storage entry area 14, the storage entry and exit area 11, the inspection area 12, and the central control operation area 13 are integrated into the main box 1. The main box 1 is sequentially provided with the storage entry and exit area 11, the inspection area 12, and the central control operation area 13 in the direction away from the connecting port. The storage entry area 14 is located next to the storage entry and exit area 11. The curing area 21 is integrated into the curing box 2, and a movable stacker 8 is provided between the inspection area 12 and the curing area 21. When in use, it is only necessary to transport the main box body 1 and the curing box body 2 to the construction site, splice the connecting ports of the main box body 1 and the curing box body 2 together, and through the layout of each functional area, the sample can be transferred between the transfer storage rack 81 and the storage area 14, the curing area 21 and the testing area 12 through the pick-up and placement mechanism 82 of the stacker 8, so that the concrete can be cured and tested in real time at the construction site. The system has high integration and strong flexibility, effectively ensuring the timeliness of concrete curing and testing, while reducing the cost of concrete transportation, improving construction efficiency, and avoiding the problems of long construction period, increased cost and increased carbon dioxide emissions caused by the temporary construction of the on-site curing system. On the other hand, the stacker 8 of the present invention is equipped with a pick-and-place mechanism 82 and an intermediate storage rack 81. When transferring samples, multiple samples can be temporarily stored in the intermediate storage rack 81, thereby ensuring that a larger number of samples are transferred at a single time, effectively improving the transfer efficiency, and reducing the number of times the stacker 8 enters and exits the curing area 21 when taking samples, thereby avoiding changes in humidity and temperature in the curing area 21 due to multiple entries and exits, ensuring the stability of the environment in the curing area 21, and ensuring the quality of curing.

[0054] Among them, see Figure 1 、 Figure 4 and Figure 5 As shown, when the system of the present invention is used, different specifications and quantities of curing boxes 2 can be selected as needed. For example, when the number of curing items is small, a smaller curing box 2 can be selected. When the number of curing items is large, a larger curing box 2 can be selected. Alternatively, two curing boxes 2 can be spliced together to form a curing area 21. The overall flexibility of the system is higher.

[0055] In some embodiments, see Figure 1 、 Figure 3 、 Figure 6 and Figure 7 As shown, the in-and-out storage area 11 is provided with a first track 15 for the stacker 8 to slide, and the end of the first track 15 away from the connecting port forms an outbound position 16;

[0056] The testing area 12 is provided with a strength testing device 3 for testing the strength of the sample and a sample entry and exit device 4 for feeding the sample into or out of the strength testing device 3. A storage turntable 5 for a stacker 8 to place the sample is provided between the strength testing device 3 and the sample entry and exit device 4. The strength testing device 3, the storage turntable 5 and the sample entry and exit device 4 are arranged in a vertical direction along the first track 15.

[0057] The outbound turntable 5 includes a conveying platform 51 . The conveying direction of the conveying platform 51 is parallel to the first track 15 . The outbound position 16 is located at a loading end of the conveying platform 51 .

[0058] The process of transferring the sample from the curing area 21 to the testing area 12 (i.e., the outbound process) is as follows:

[0059] After the curing of the sample expires, the stacker 8 takes the expired sample from the curing area 21 to the intermediate storage rack 81, and then the stacker 8 moves to the outbound position 16, and places the sample in the intermediate storage rack 81 on the conveying table 51 through the pick-up and placement mechanism 82. At this time, the conveying table 51 is in the starting state, and moves the sample at its loading end away from the outbound position 16, so that the stacker 8 can load multiple samples only at the outbound position 16.

[0060] The strength test process of the sample is as follows:

[0061] The conveying table 51 conveys a sample thereon to a corresponding position of the sample inlet and outlet device 4 , and then the sample inlet and outlet device 4 pushes the sample into the strength detection device 3 , and then the strength detection device 3 can perform strength detection on the sample.

[0062] After the test is completed, the sample inlet and outlet device 4 pushes the sample out of the strength testing device 3.

[0063] In the present invention, a strength detection device 3, an outbound turntable 5 and a sample entry and exit device 4 are arranged in the detection area 12, and the strength detection device 3, the outbound turntable 5 and the sample entry and exit device 4 are arranged along the vertical direction of the first track 15, so that the stacker 8 can realize the outbound delivery of multiple samples at the outbound position 16. At the same time, the samples after outbound delivery can be smoothly tested through the cooperation between the strength detection device 3, the outbound turntable 5 and the sample entry and exit device 4. The overall layout is compact and the sample turnover is smooth, which is conducive to the smooth progress of the samples in different steps such as outbound delivery and testing.

[0064] In some embodiments, see Figure 1 、 Figure 6 and Figure 7 As shown, the strength detection device 3 includes a test table 31, a pressure head 32 provided above the test table 31, and a driving component for driving the pressure head 32 to move up and down. For example, the driving component can be a cylinder, a hydraulic cylinder, etc.

[0065] A transition table 6 is provided between the conveying table 51 and the testing table 31;

[0066] The sample in-and-out device 4 includes a base frame 41. An end of the base frame 41 facing the strength detection device 3 is provided with a pressure head detection component 44 for detecting the current state of the pressure head 32. The base frame 41 is provided with a pushing component 42 for pushing the sample and a pushing drive mechanism 43 for driving the pushing component 42 to move back and forth in a horizontal direction close to or away from the test table 31. Exemplarily, the pressure head detection component 44 can be an optical detector, such as an infrared detector.

[0067] Before pushing the sample into the test table 31, the sample in-and-out device 4 detects whether the pressure head 32 is currently pressed on the test table 31 through the pressure head detection part 44. If not, the pushing drive mechanism 43 can be started, and the pushing drive mechanism 43 drives the pushing part 42 to push the sample from the conveying table 51 to the transition table 6 to the test table 31, and then the pressure head 32 is controlled to descend to press the sample to detect the strength of the sample.

[0068] After the test is completed, the indenter 32 rises, and the indenter detection member 44 detects that the indenter 32 has left the test table 31 and starts the push drive mechanism 43 , which drives the push member 42 to push the sample out of the test table 31 .

[0069] The present invention ensures smooth progress of sample strength testing through the cooperation between the sample inlet and outlet device 4 and the strength testing device 3 .

[0070] In some embodiments, see Figure 6 and Figure 7 As shown, the pushing drive mechanism 43 includes a first stroke component and a second stroke component. The first stroke component includes a first cylinder 431. The movable end of the first cylinder 431 is connected to the pushing member 42. The second stroke component includes a slide rail arranged in a parallel direction along the movement of the pushing member 42. A sliding seat 433 is movably provided on the slide rail. The cylinder body of the first cylinder 431 is arranged at the bottom of the sliding seat 433. A second cylinder 432 is provided above the sliding seat 433. The movable end of the second cylinder 432 is connected to the sliding seat 433.

[0071] The pushing member 42 pushes the sample from the conveying table 51 to the testing table 31 via the first stroke component. The pushing member 42 pushes the sample from the inside of the testing table 31 to the outside of the testing table 31 via the first stroke component and the second stroke component.

[0072] Specifically, the steps of pushing the sample from the conveying table 51 to the testing table 31 by the pushing member 42 via the first stroke assembly are as follows:

[0073] The movable end of the first cylinder 431 extends outward, driving the pushing member 42 to move, thereby pushing the sample from the conveying table 51 to the testing table 31 .

[0074] The steps of the pusher 42 pushing the sample from the inside of the test table 31 to the outside of the test table 31 via the first stroke component and the second stroke component are as follows:

[0075] The movable end of the second cylinder 432 moves, driving the sliding seat 433 to move along the slide rail toward the test table 31, and the first cylinder 431 and the pushing member 42 are driven to move toward the test table 31. At the same time, the movable end of the first cylinder 431 extends outward, driving the pushing member 42 to move, thereby allowing the pushing member 42 to have a longer moving stroke, thereby pushing the sample from the inside of the test table 31 to the outside of the test table 31.

[0076] In the present invention, through the mutual cooperation between the first stroke component and the second stroke component, the sample inlet and outlet device 4 can also have the function of sending the sample into or out of the strength detection device 3, the system integration is higher, and at the same time, the control of the device is simpler.

[0077] In some embodiments, see Figures 1 to 3 As shown, the central control operation area 13 includes a controller (not shown), and the control method of the controller includes:

[0078] S100. Drive the stacker 8 to execute the warehousing instruction:

[0079] The stacker 8 is driven to move to the side of the storage area 14, and the sample is transferred from the storage area 14 to the intermediate storage rack 81 through the pick-and-place mechanism 82. Then, the stacker 8 is driven to move to the curing area 21, and the sample is transferred from the intermediate storage rack 81 to the curing area 21 through the pick-and-place mechanism 82.

[0080] Record the sample curing information, including curing time, curing temperature, and curing humidity.

[0081] S200. Drive the stacker 8 to execute the outbound instruction:

[0082] After the sample curing expires, the stacker 8 is driven to move to the curing area 21, and the sample is transferred from the curing area 21 to the intermediate storage rack 81 through the pick-and-place mechanism 82. Then, the stacker 8 is driven to move to the outbound position 16, and the sample is transferred from the intermediate storage rack 81 to the conveying table 51 through the pick-and-place mechanism 82.

[0083] The stacker 8 can perform storage and retrieval operations of samples after receiving instructions from the controller, and the system has a high degree of automation.

[0084] In some embodiments, see Figure 2 、 Figure 9 and Figure 10As shown, the stacker 8 includes a frame and a moving mechanism 85 for driving the frame to move, the pick-and-place mechanism 82 and the intermediate storage rack 81 are arranged on the frame, the pick-and-place mechanism 82 is arranged outside the intermediate storage rack 81, and a lifting component 86 for driving the pick-and-place mechanism 82 to rise and fall is provided between the pick-and-place mechanism 82 and the frame, and the pick-and-place mechanism 82 includes a pick-and-place arm 83 that can be retracted inside and outside the intermediate storage rack 81 and a rotating component 84 for driving the pick-and-place arm 83 to rotate in the horizontal direction.

[0085] Taking the stacker 8 executing the outbound instruction as an example, the operation process is as follows:

[0086] The stacker 8 enters the curing area 21 through the moving mechanism 85 and moves to the side of the curing rack 22 where the sample to be taken is placed. The rotating component 84 drives the pick-up and placement arm 83 to turn to the side where the sample is located, and the lifting component 86 lifts the pick-up and placement arm 83 to an appropriate height. Then the pick-up and placement arm 83 takes the sample from the curing rack 22, retracts the pick-up and placement arm 83 and rotates the pick-up and placement arm 83 to the side where the intermediate storage rack 81 is located through the rotating component 84, and then extends the pick-up and placement arm 83 into the intermediate storage rack 81 to place the sample just taken out of the curing rack 22 by the pick-up and placement arm 83 into the intermediate storage rack 81, thereby completing the operation of transferring the sample to the intermediate storage rack 81. The above operation of transferring the sample to the intermediate storage rack 81 can then be repeated multiple times. Then, the stacker 8 that has obtained the sample is transported to the outbound position 16 by the moving mechanism 85, and then the sample is transferred from the intermediate storage rack 81 to the outbound turntable 5 by the pick-up and placement mechanism 82 for performance testing.

[0087] When the stacker 8 executes the warehousing instruction, that is, when the sample is transferred from the warehousing area 14 to the curing area 21, the operation of the pick-up and place mechanism 82 on the stacker 8 is similar to the above operation and will not be repeated here.

[0088] In this embodiment, an intermediate storage rack 81 and a pick-and-place mechanism 82 having a pick-and-place arm 83 that can be retracted inside and outside the intermediate storage rack 81 are provided in the stacker 8, and the pick-and-place mechanism 82 can be rotated and lifted by a rotating component 84 and a lifting component 86, so that the stacker 8 can temporarily store the objects to be transferred in the intermediate storage rack 81 at the picking point, and then take them out from the intermediate storage rack 81 after transporting them to the destination. In this way, the stacker 8 can transfer a larger number of objects to be transferred at a time, effectively improving efficiency, and can effectively reduce the number of times the stacker 8 enters and exits the curing area 21 when taking samples, thereby ensuring the stability of the environment in the curing area 21.

[0089] The moving mechanism 85 can move by driving a gear through a motor and then driving a roller coaxially arranged with the gear, which will not be described in detail here.

[0090] The rotating assembly 84 can realize the rotation of the rotating seat by driving the rotating seat through a rotating motor. The rotating seat is arranged under the pick-and-place arm 83 and will not be described in detail here.

[0091] The lifting assembly 86 can realize the lifting of the lifting seat through mutually meshing gear racks and a lifting motor. The pick-and-place mechanism 82 is provided on the lifting seat and will not be described in detail here.

[0092] In some embodiments, see Figure 2 、 Figures 9 to 11 As shown, the pick-and-place arm 83 includes a fixed rail 831, a support plate 832 slidably disposed on the fixed rail 831, and a telescopic assembly 833 for driving the support plate 832 to extend and retract in the horizontal direction;

[0093] The telescopic assembly 833 includes an extension rail 8331 slidably mounted on the fixed rail 831 , and a support plate 832 slidably mounted on the extension rail 8331 . The pick-and-place arm 83 is further provided with a driving member for driving the extension rail 8331 and the support plate 832 to extend and retract along the length direction of the extension rail 8331 .

[0094] The support plate 832 can support the sample, and combined with the lifting mechanism and the telescopic component 833, the sample can be taken and placed. For example, the telescopic component 833 can include a telescopic cylinder (not shown).

[0095] When in use, the driving member drives the extension rail 8331 and the support plate 832 to extend in the direction away from the fixed rail 831 or to fold in the direction close to the fixed rail 831 along the length direction of the extension rail 8331. The extension rail 8331 can make the support plate 832 extend to a position farther away from the fixed rail 831. Compared with the implementation scheme of simply using the telescopic cylinder to drive the support plate 832 to extend and retract, by arranging the extension rail 8331 between the fixed rail 831 and the support plate 832, the fixed rail 831 and the extension rail 8331 are 8331 and the support plate 832 cooperate with each other to form a three-stage retractable structure, so that the overall length of the pick-and-place arm 83 is shorter in the retracted state, and it is less likely to interfere with the frame when rotating, especially when rotating to the side where the intermediate storage rack 81 is located. At the same time, the extended length of the pick-and-place arm 83 in the extended state is longer, which is conducive to taking out samples located deeper in the curing rack 22, making it more convenient to take and place samples. At the same time, the frame, the intermediate storage rack 81 and the pick-and-place arm 83 can be installed more compactly, and the overall layout of the stacker 8 is more compact.

[0096] In some embodiments, preferably, see Figure 2 、 Figures 8 to 11As shown, the driving member includes a telescopic driving motor 8334, a meshing gear is provided on the fixed rail 831, the meshing gear is connected to the telescopic driving motor 8334, the extension rail 8331 is provided with a transmission rack 8335 for meshing with the meshing gear, and the transmission rack 8335 is arranged along the length direction of the extension rail 8331; the telescopic assembly 833 also includes a transmission chain, and a first rotating wheel 8311 and a first connecting end 8312 are sequentially provided on the fixed rail 831 along the outward extension direction of the support plate 832, and the extension rail 83 A second rotating wheel 8332 and a chain groove 8333 are sequentially provided along the outward extension direction of the support plate 832 on 31. A second connecting end 8321 is provided on the support plate 832. One end of the transmission chain is connected to the first connecting end 8312, and the other end is connected to the second connecting end 8321 by passing through the first rotating wheel 8311, the second rotating wheel 8332, and the chain groove 8333 in sequence. The first rotating wheel 8311, the second rotating wheel 8332, and the chain groove 8333 can limit the reciprocating movement direction of the transmission chain from deviation.

[0097] When the picking and placing arm 83 needs to extend outward, the telescopic drive motor 8334 drives the meshing gear to rotate, and the transmission rack 8335 meshing with it is driven to move outward along the length direction of the extension rail 8331. The extension rail 8331 extends outward, and the second connection end 8321 is driven to move accordingly. The chain segment of the transmission chain from the first connection end 8312 to the second rotating wheel 8332 becomes shorter, and the chain segment of the transmission chain from the second rotating wheel 8332 to the second connection end 8321 becomes longer accordingly, driving the support plate 832 to extend outward relative to the extension rail 8331.

[0098] When the pick-and-place arm 83 needs to retract inward, the telescopic drive motor 8334 drives the meshing gear to rotate, and the transmission rack 8335 meshing with it is driven to move inward along the length direction of the extension rail 8331. The extension rail 8331 moves inward, and the second connection end 8321 is driven to move accordingly. The chain segment of the transmission chain from the first connection end 8312 to the second rotating wheel 8332 becomes longer, and the chain segment of the transmission chain from the second rotating wheel 8332 to the second connection end 8321 becomes shorter, driving the support plate 832 to move inward relative to the extension rail 8331.

[0099] Through the cooperation of the telescopic drive motor 8334, the meshing gear, the transmission rack 8335 and the transmission chain, the same power element can drive the movement of the extension rail 8331 and the support plate 832, the integration of the pick-and-place arm 83 is higher, and the retraction control is simpler.

[0100] Among them, there are two groups of transmission chains, which are respectively arranged on both sides of the width direction of the extension rail 8331, so that the transmission is more stable.

[0101] In some embodiments, a gear set is provided between the telescopic drive motor 8334 and the meshing gear, and the fixed rail 831 is provided with a bar-shaped accommodating groove 8313, which is arranged along the length direction of the extension rail 8331, and the meshing gear and the gear set are arranged in the bar-shaped accommodating groove 8313, and the transmission rack 8335 at least partially extends into the bar-shaped accommodating groove 8313 and meshes with the meshing gear.

[0102] In some embodiments, the transmission chain may include a chain and connecting rods provided at both ends of the chain, and the connecting rods are respectively connected to the first rotating wheel 8311 and the first connecting end 8312, which is beneficial to the stability of the transmission.

[0103] In another embodiment, the driving member includes power elements for controlling the extension and retraction of the extension rail 8331 and the support plate 832 respectively.

[0104] In some embodiments, see Figures 1 to 3 and Figure 8 As shown, the storage area 14 includes a turnover rack 141 for placing samples to be stored, and a size detection device 142 for detecting the size of the samples to be stored is provided on one side of the turnover rack 141 close to the connecting port.

[0105] The samples can be put into storage as a whole through the turnover rack 141, which makes the storage of samples more convenient and quick. The size detection device 142 can preliminarily detect whether the samples meet the size requirements and conduct a preliminary screening of the size qualification of the samples.

[0106] Exemplarily, the dimension detection device 142 can detect the length, width, and height of a specimen using methods such as laser range sensors, visual inspection systems, and three-dimensional coordinate measuring machines. Specifically, the method based on laser range sensors refers to measuring the specimen from different directions using multiple laser range sensors to obtain dimension information such as the length, width, and height of the specimen; the method based on visual inspection systems refers to measuring the dimensions of the specimen by analyzing the image of the specimen using a camera and image processing technology; and the method based on three-dimensional coordinate measuring machines refers to determining the spatial position of the specimen using three mutually perpendicular coordinate axes and obtaining coordinate data by contacting a probe with the specimen surface, thereby accurately measuring the length, width, height, and other geometric parameters of the specimen. These methods will not be further described here.

[0107] Preferably, since most samples are simple and regular rectangular parallelepiped structures, the size detection device 142 can use a laser ranging sensor to achieve size detection, which is lower in cost and simpler in detection.

[0108] In some embodiments, see Figure 1 and Figure 2As shown, the side walls and the top of the curing box 2 are provided with an insulation layer, and a curing rack 22 for placing samples and a second track 23 for the stacker 8 to slide are provided in the curing area 21. The curing rack 22 is provided beside the second track 23 to facilitate the stacker 8 to place the sample on the curing rack 22 or take the sample out of the curing rack 22, and a humidity regulator 24 is provided in the curing area 21. A drying area 17 is provided at one end of the inlet and outlet area 11 near the connecting port, and air curtain devices 7 are provided at both ends of the drying area 17 in a direction parallel to the second track 23.

[0109] The first track 15 may include an upper track and a lower track, and the second track 23 is similar, which will not be described in detail here.

[0110] In the present invention, an insulation layer is provided on the side walls and the top of the curing box 2 to ensure the temperature stability in the curing area 21 and reduce energy consumption. The humidity in the curing area 21 is adjusted by the humidity regulator 24 to ensure that the humidity requirements for curing are met. Exemplarily, the humidity regulator 24 can be a humidifier, and the curing area 21 is further isolated by the air curtain device 7, thereby ensuring the overall stability of the environment of the curing area 21 and ensuring the quality of curing.

[0111] At the same time, a drying area 17 is provided at one end of the inlet and outlet area 11 near the connecting port. Since the humidity in the curing area 21 is relatively high, the stacker 8 is dried in time in the drying area 17 to prevent its parts from getting damp, thereby extending the service life of the stacker 8. In addition, by arranging air curtain devices 7 at both ends of the drying area 17 in a direction parallel to the second track 23, the drying area 17 is isolated, thereby improving the drying effect and reducing energy consumption.
