Description

Technical Field

[0001] The utility model relates to the technical field of concrete compression resistance detection, in particular to a concrete compression resistance test piece curing system. Background Art

[0002] Concrete is one of the most widely used materials in the construction industry, and concrete curing is a crucial step in ensuring that concrete achieves its designed strength and service life. With the acceleration of urbanization and rapid advancements in the construction industry, concrete curing technology faces new opportunities and challenges. Urbanization is driving higher demands for structural safety and service life. Concrete curing is crucial for ensuring the long-term, stable operation of buildings and infrastructure, and as a result, demand for concrete curing is expected to continue to grow.

[0003] The current standard curing process for concrete compressive specimens has a low level of intelligence and automation, requiring significant manpower to move the specimens to the curing room's multi-level shelves of varying heights. For example, a concrete compressive specimen curing rack, as proposed in Chinese Patent Publication No. CN210282682U, requires staff to enter the curing room to select and remove expired specimens after their curing period. Because the curing room's temperature is 20°C ± 2°C and the relative humidity is above 95%, pathogens and other microorganisms can easily breed in this environment, posing a threat to the health and safety of workers. Furthermore, visibility is low and the floor is slippery, making it difficult to remove expired specimens. This can lead to incomplete selection and omissions, resulting in incomplete or erroneous test data. Furthermore, selecting and transporting a large number of specimens within a limited curing space is labor-intensive, resulting in high labor costs and low efficiency. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-8 As shown, the utility model provides a concrete compression specimen curing system, including a curing chamber 1 for providing a certain temperature and humidity curing environment for the concrete compression specimen 10, a handling component for transferring the concrete compression specimen 10 between the curing chamber 1 and the inspection pallet 6, a code scanning system 17 for identifying the identity of the concrete compression specimen 10, a plate chain conveying system 3 for transferring and storing the concrete compression specimen 10 from the entrance to the exit in the curing chamber 1, and a control system for controlling the work of each component to manage the warehousing action, identity information, age information, location information, and outbound action of the concrete compression specimen.

[0027] Observation windows 2 are provided on both sides of the curing room 1 to facilitate observation of the curing status of the concrete compression test piece 10; a number of automatic doors 7 are provided at the front and back of the curing room 1 for entry and exit of the warehouse. The automatic doors 7 are opened or closed by the control system. At the same time, sensors are installed on the doors to determine whether the doors are fully opened or fully closed. The automatic doors and sensors are respectively communicated with the control system and can also be electrically connected. Closing the door can achieve sealing to protect the curing environment inside the curing room.

[0028] The handling assembly includes a robotic arm 5, a compression test piece clamp 9 and a mobile platform, which are used for transporting the concrete compression test piece 10 between the curing room 1 and the inspection pallet 6. The mobile platform 4 is fixed in front of the automatic doors in front and behind the curing room 1. The robotic arm 5 is installed on the mobile platform 4 through a slide rail assembly, and is slidably connected to the mobile platform 4. It can move laterally on the mobile platform 4, thereby expanding the arm span range of the robotic arm 5. A compression test piece clamp 9 is installed at the end of the robotic arm 5, which can grab the compression test piece 10 and place it in a specified position inside the automatic door 7 in front of the curing room 1, or can take out the concrete compression test piece 10 from a specified position in the automatic door 7 behind the curing room 1 and place it in a specified position.

[0029] The concrete compressive specimen identification system includes a positioning platform 16 and a code scanning system 17. The code scanning system 17 is used to identify the identity information of the concrete compressive specimen. The code reading device is installed near the pallet to be inspected. The code on the compressive specimen is identified after the outbound action or before the inbound action. After identification, it is compared with the compressive specimen identity information in the task instruction. If it meets the requirements, the next action is executed. A positioning fixture 22 is provided on the positioning platform 16, and an alignment cylinder 23 is provided under the positioning platform 16. The concrete compressive specimen identity identification system is communicatively connected to the control system and can also be electrically connected.

[0030] The plate chain conveyor system is used to transport and store concrete compression test specimens from the entrance to the exit of the curing room. It includes conveyor chains, sprockets, chain plates, servo motors, reducers, and frames. Several plate chain conveyors are stacked together for use. The compression test specimens are placed sequentially on the chain plates of the plate chain conveyor. The chain plates are C-shaped bends to increase the pressure-bearing strength. The bottom of the chain plates are provided with ventilation holes to ensure that the bottom of the compression test specimens is fully cured. A dust box is installed in the middle layer of the plate chain conveyor to prevent debris from the surface of the compression test specimens from falling into the conveyor and affecting the normal operation and service life of the equipment. A rubber scraper and dust box are installed on the lower side of the tail of the plate chain conveyor to prevent debris from the compression test specimens from falling onto the ground, the lower conveyor, or the compression test specimens.

[0031] The control system can control the communication connections (also electrically connected) of the robotic arm 5, plate chain conveyor, automatic door 7, code scanning device 24, etc., and is used to manage the warehousing action, identity information, age information, location information, and outbound action of concrete compression test pieces.

[0032] During operation: the staff will stick the identity code on the designated surface of the compression test piece 10 in turn, place it in the inspection tray 6 in order, and transport the inspection tray 6 containing the compression test piece to the inspection tray positioning seat next to the robotic arm 5 for positioning. The staff will enter the number of compression test pieces to be cured on the touch screen industrial computer 15 of the control system, check that the system meets the conditions for starting operation, and click to start operation. After the robotic arm 5 clamps the compression test piece 10, it is placed on the positioning platform 16 for secondary positioning. The code scanning device 24 reads the QR code on the surface of the compression test piece 10 and transmits the information of the compression test piece 10 to the control system. The control system can compare the age of the compression test pieces on several plate chain conveyors in the curing room based on this information, select the most reasonable one according to certain rules, and determine the location of the compression test piece. After the work station is determined, the automatic door 7 opens, and the robotic arm 5 puts the compression test piece 10 through the automatic door 7 into the plate chain No. 1 position of this work station. After 6 compression test pieces are placed in sequence, the plate chain conveyor advances one grid. Similarly, after all the compression test pieces of the same age are moved to the plate chain of this station, the automatic door 7 is closed, and the warehousing process is completed.

[0033] Place the empty pallet to be inspected on the outbound positioning seat and complete the positioning. Preferably, the control system can retrieve the age of the compression test pieces at a specified time every day according to the national standard requirements. When a compression test piece with an expired age is found, a command is issued to the corresponding plate chain conveyor. This plate chain conveyor transports the earliest compression test piece on the chain plate entering the curing room to the exit of the curing room. After transporting it to the position, the plate chain conveyor stops running, and the control system issues a command to the automatic door at the end of the plate chain conveyor to execute the door opening action and open the door into place. The robotic arm 5 enters the exit position of the automatic door 7 according to the instructions of the control system, clamps the pressure test piece 10 and places it on the positioning platform 16 for re-positioning. The code scanning device 24 performs the code reading action according to the instructions of the control system. The code reading information is uploaded to the control system and compared with the pressure test piece information of the outbound task. If it meets the requirements, the next step is performed. The robotic arm 5 performs the action of clamping the pressure test piece 10 according to the instructions of the control system and placing it in the designated position on the inspection tray 6 in turn until all the pressure test pieces 10 that need to be shipped out are stacked on the inspection tray 6. At this point, the outbound action is completed.
